SummaryThe paper presents milk production results in a domestic Balkan goat breed reared in the north-western region of the Sharplanina massif. A characteristic of the domestic Balkan goat is that it is reared under poor conditions where other domestic animals can not find enough food to survive. These goats have a strong constitution, are robust and resistent to contagious and parasitic diseases, tolerant to hot, arid climate, and have modest nutritional requirements. The entire body (except the nose, hoofs, and lower portion of the tail) is covered by hair. Hair color varies. Most often it is reddish or gray, but can also be black, as well as chestnut, brown, patchy, and seldom, white. Body size increases with age, due to the fact that the domestic Balkan goat matures late, reaching full size at about 4 years of age. Mean values for height at withers and body length in mature goats were 66 and 70 cm, respectively. Lactation duration was 238 days, total milk production 178 kg per lactation, milk fat 3.68%. An average of 1.2 kids are obtained per goat annualy. Poor fertility of the domestic Balkan goat is caused by numerous reasons, mainly poor nutrition.

Nine fully recognized and described species of coccidia in goats and also one species not previously described are identified. Size shape, colour, sporulation time, morphology of unsporulated oocysts were the criteria for species identification 30 out of 36 faecal sample were positive form single or mixed infections with 3 samples being pure infections of single species. The unidentified species has a low occurrence and probably is not of importance in clinical coccidiosis in goats. The sporulation time for different species is found to be directly related to the size of the oocysts. As most species sporulate within 48 hours, daily removal of faecal materials form goat pens is recommended

Full textAbstract:
The paper presents results of investigations of the domestic Balkan goat reared in the Sharplanina mountainous region pertaining to phenotypic correlations between the most important production traits (milk production traits for 578 goats), and growth traits of kids (for 710 kids in the suckling period). Research was done in herds of Balkan goats belonging to private farmers, during a two-year period. Simple correlation between mentioned traits were calculated using a PC and the LSMLMW program (Harvey, 1990). Data pertaining to correlation coefficients established between investigated milk production traits of the domestic Balkan goat, reflect existing correlations, which in most cases, were positive and statistically significant (P<0,01). Very strong correlations were established between the 1st and 2nd milk production control, as well as between the daily milk yield and the 2nd milk production control (0.796), as well as the total milk yield (0.870). Established coefficient were also statistically significant (P<0,01). Correlation between birth weight and the weight at specific ages (30, 60 and 90 days) were strong and very strong, while correlations between birth weight and average daily weight gain established by individual months (0.526, 0.553 and 0.384) varied between weak and strong, with an established weakening of correlations with advancing age.

Full textAbstract:
Feral goats (Capra hircus) are increasing in abundance and distribution in the semi-arid and arid rangelands of New South Wales, and elsewhere in the southern rangelands. They present a conundrum for natural resource managers and policy-makers as they can be both an agricultural and environmental pest and an economic resource for landholders. This paper presents an economic analysis of a range of alternative approaches to feral goat management and assesses their implications for natural resource management policies. ‘Opportunistic harvesting’ and ‘value-added’ strategies (the latter involving use of a paddock to increase the liveweight of feral goats before slaughter for meat) returned positive net benefits to landholders, whereas the strategy of ‘no management’ resulted in a negative net benefit if the overall stocking rate was held constant. The erection of goat-proof boundary fencing to enhance production from domestic livestock generated negative net benefits unless increases in stocking rates of domestic livestock could be achieved within the exclusion fencing through improved grazing management. The use of goat-proof fencing to establish an individual paddock for domestic livestock production returned positive net benefit for landholders but also required increases in domestic stocking rate to be competitive with the best feral goat harvesting strategy. The ‘opportunistic harvesting’ and ‘value added’ strategies are thus likely to be adopted by producers without financial incentive and could result in positive resource conservation outcomes if goat prices encourage harvesting. The ‘no management’ strategy will most likely promote resource degradation and should be discouraged. Strategies involving goat-proof fencing are likely to provide positive net benefits for landholders and achieve positive natural resource outcomes if associated with improved grazing management, and reduced density of feral goats outside the exclusion fencing. It is concluded that resource conservation benefits of feral goat control strategies may be positive, negative, or neutral depending on the management strategy adopted, the extent of goat-proof fencing, and the price of meat from feral goats. It is, therefore, difficult to rely on the commercial harvesting of feral goats to achieve resource conservation objectives. Public funds could be better used to support education and training in grazing management and provide incentives for achievement of measurable natural resource outcomes than to support infrastructure establishment for the harvesting of feral goats on private properties.

Dissertação de Mestrado Integrado em Medicina VeterináriaA cabra-montesa (Capra pyrenaica) é uma espécie endémica da Península ibérica, uma das mais emblemáticas do Parque Nacional da Peneda-Gerês. Contam-se 13 anos desde o regresso deste ungulado silvestre a território português depois de a espécie ser considerada extinta em 1890. A presença crescente de gado doméstico e assilvestrado, sobretudo de caprinos, nas áreas ocupadas pelas cabras montesas constitui uma das principais ameaças à conservação da espécie, quer devido ao aumento da prevalência e transmissão de doenças, quer devido à competição pelos recursos naturais. Posto isto, torna-se importante a monitorização e controlo deste tipo de rebanhos. Neste contexto, elaborou-se um estudo sobre a parasitofauna de 27 núcleos de caprinos residentes na área do PNPG através da recolha de 50 amostras de fezes, pertencentes a cabras-montesas (Capra pyrenaica, n=22), cabras domésticas (Capra hircus, n=20) e cabras assilvestradas (Capra hircus, n=8). Em Portugal, é a primeira vez que se realiza um estudo deste género na cabra-montesa. No total das 50 amostras, 98% (n=49) apresentaram formas parasitárias pertencentes a pelo menos um dos 9 géneros/espécies identificados e com as seguintes prevalências: Muellerius capillaris (100%, n=22 cabra-montesa, n=20 cabra doméstica, 75%, n=6 cabra assilvestrada), Nematodirus (100%, n=20 cabra doméstica, 95,5%, n=21 cabra-montesa, 25%, n=2 cabra assilvestrada), Teladorsagia (65%, n=13 cabra doméstica, 22,7%, n=5 cabra-montesa, 12,5%, n=1 cabra assilvestrada) Trichostrongylus (45%, n=9 cabra doméstica, 13,6%, n=3 cabra-montesa, 12,5%, n=1 cabra assilvestrada), Moniezia benedeni (35%, n=7 cabra doméstica, 22,7%, n=5 cabra-montesa, 12,5%, n=1 cabra assilvestrada), Dicrocoelium dendriticum (5%, n=1 cabra doméstica), Trichuris ovis (5%, n=1 cabra doméstica), Eimeria (70%, n=14 cabra doméstica, 59,1%, n=13 cabra-montesa, 37,5%, n=3 cabra assilvestrada) e Cryptosporidium (20%, n=4 cabra doméstica, 13,6%, n=3 cabra-montesa, 12,5%, n=1 cabra assilvestrada). De uma forma geral, a parasitofauna encontrada nas 3 populações foi muito semelhante, tendo-se registado intensidades parasitárias baixas, o que não invalida a necessidade da continuação de estudos de monitorização destas populações de caprinos.
ABSTRACT - Parasitological survey on wild, feral and domestic goat’s populations from Peneda-Gerês National Park - The Iberian ibex is endemic to the Iberian Peninsula, one of the most emblematic species from Peneda-Gerês National Park. Is has passed 13 years since the return of this wild ungulate to Portuguese territory, after this specie be considered extinct at 1890. The increasing presence of livestock, specially domestic and feral goats, at the Iberian ibex’s range, is one of the main threats to ibex conservation, either because of the increase of diseases prevalence and transmission rates, but also due the competition to natural resources. Therefore, it’s important to monitor and control these types of flocks. In this context, a parasitological study was developed in 27 goat’s nuclei inhabiting the national park’s range from the collection of feces bellowing to Iberian ibexes (Capra pyrenaica, n=22), domestic goats (Capra hircus, n=20) and feral goats (Capra hircus, n=8). In Portugal this was the first study of this kind on Iberian ibex. In a total of 50 samples, 98% (n=49) shown to be positive for at least one parasite of the 9 identified genera/species and there were the following prevalences: Muellerius capillaris (100%, n=22 Iberian ibex, n=20 domestic goat, 75%, n=6 feral goat), Nematodirus (100%, n=20 domestic goat, 95,5%, n=21 Iberian ibex, 25%, n=2 feral goat), Teladorsagia (65%, n=13 domestic goat, 22,7%, n=5 Iberian ibex, 12,5%, n=1 feral goat) Trichostrongylus (45%, n=9 domestic goat, 13,6%, n=3 Iberian ibex, 12,5%, n=1feral goat), Moniezia benedeni (35%, n=7 domestic goat, 22,7%, n=5 Iberian ibex, 12,5%, n=1 feral goat), Dicrocoelium dendriticum (5%, n=1 domestic goat), Trichuris ovis (5%, n=1 domestic goat), Eimeria (70%, n=14 domestic goat, 59,1%, n=13 Iberian ibex, 37,5%, n=3 feral goat) e Cryptosporidium (20%, n=4 domestic goat, 13,6%, n=3 Iberian ibex, 12,5%, n=1 feral goat). In general, the parasitic fauna encountered at the three goat’s population was very similar, with low parasitic’s intensity, but it cannot be underestimated the need of continuing the monitoring study’s on these goat’s population.

The purpose of my study is to compare the academic experiences of international students with those of domestic students at the University of New Orleans (UNO). Specifically, I aimed the study towards determining international students’ perceptions and expectations of UNO, and assessing whether or not UNO’s ability to meet their expectations had an impact on student success or failure at UNO. To test this, I asked various international and domestic students to respond to a survey consisting of both open-ended and multiple choice questions. The open-ended questions were designed to capture the student experiences on expectations, academic atmosphere, and overall college life, all of which are likely to vary from one student to the other. The multiple choice questions were on student status, tenure, and other items that can easily be classified into distinct categories. I collected and analyzed the surveys over a period of four months to decide which variables in the international students’ experiences affect their academic career. In addition, I questioned if any of the stated variables aided in campus adjustment or helped meet the student expectations regarding school performance and goals. Results indicate that the majority of students, both domestic and international, feel their academic expectations are being met by what UNO has to offer. Those students who feel their expectations (of what UNO would provide them) are not met indicated their academic performance is reflective of their own efforts, an idea that students feel is fostered by UNO. However, there was no significant factor that may have helped or deterred positive experience overall.

Full textAbstract:
Merino sheep are the most numerous domestic livestock in Australia and feral
goats are wide-spread and locally abundant in many of the regions where sheep
are grazed. Foot and mouth disease (FMD) is a disease of ungulates that causes
severe economic hardship to countries where outbreaks occur or where it has
become endemic. In India, Africa, Greece and recently the United Kingdom and
Eire, sheep and goats have been implicated in the spread and maintenance of
FMD. In Australia, there are contingency plans (AUSVETPLANS) for dealing with
an outbreak of FMD. Included in those plans are strategies for control of the
disease in feral ungulates including feral pigs and feral goats. Modelling has
provided assistance in developing strategies to combat outbreaks in feral pigs and
for controlling outbreaks in domestic livestock. No models have been constructed
to aid decisions about controlling FMD in feral goats where they co-occur with
merino sheep.
In Australia, the greatest densities of free-ranging feral goats and domestic
livestock occur in the high rainfall zone (> 500 mm mean annual rainfall) along the
eastern tablelands and adjacent slopes of the Great Dividing Range. Previous
studies of feral goat biology, population dynamics and behaviour in Australia have
concentrated on arid and semi-arid zones or on islands. Interactions between free
ranging feral goats and merino sheep have not previously been studied in the high
rainfall zone.
My study investigated the ecological and behavioural characteristics of feral goats
and their interactions with sympatric merino sheep at a high rainfall site in central
eastern New South Wales. The population dynamics, biological and behavioural
parameters of feral goats and sheep were then used to model FMD in such an
environment. Deterministic temporal models and a new spatial stochastic model
were used. Of particular interest were the rates of contact within and between
subgroups of feral goats (termed herds and mobs), within and between subgroups
of merino sheep (termed flocks and mobs), and between subgroups of the two
species.
Feral goats at the study site were found to be numerous (mean density = 34.94
goats km-2, from aerial surveys), in good condition, fecund and had high adult
survival and low annual adult mortality (survival= 0.81�1.00) in the absence of
harvesting and hunting. They had an observed instantaneous rate of increase of
0.112 per year. Annual rate of increase was similar to other sites in Australia
without sustained harvesting pressure. Home ranges were small for both males
(3.754 km², s.e. = 0.232, n = 116 goats) and females (2.369 km², s.e. = 0.088, n =
241 goats). From this and other Australasian studies, an inverse power function
was found to be an excellent descriptor of the relationship between mean annual
rainfall and female home range size.
A resource selection function was fitted in a geographic information system to
observational data of feral goats. The habitat selection of feral goats included a
preference for wooded vegetation on eastern and north eastern aspects at higher
elevations. The resource selection function was also used to set the probabilities of
occurrence of feral goats in 1 ha areas of the landscape and these probabilities
were used to generate heterogeneity in a spatial model of foot and mouth disease
virus (FMDV) transmission.
Daily per capita contact rates were estimated from observed contacts in the field
where a contact between individuals was recognised when one approached within
1 body length ([approx] 1m) of another. The contacts between feral goats within herds
were frequent and occurred at a rate of 6.96 (s.e. = 1.27) goat�goat contacts day-1.
Sheep to sheep contacts were slightly less frequent (4.22 sheep�sheep contacts
day-1, s.e. = 0.65) but both estimates were most likely negatively biased because of
observer errors in estimating the number of individual animals coming in contact
with observation subject (focal) animals. Contacts between herds of feral goats
were not common and those between adjacent populations were fewer than 1 per
year. In sheep, flock to flock contact was largely governed by husbandry practices
and occurred at a mean daily rate of 0.0014 flock�flock contacts. Contacts
between sheep and feral goats were less frequent but nonetheless common (2.82
goat�sheep contacts day-1, s.e. = 0.40). In feral goats the size of the mob in which
focal goats were observed was found to be the most important factor in
determining contact rates between individuals and a counter-intuitive inverse
relationship was identified. Contacts were heterogeneous and density was not an
important determinant of contact rates implying that, because of the uniformly high
densities at the site, saturation had occurred.
The temporal models of FMDV transmission showed that the rate of contact within
and between species was such that FMD was predicted to spread rapidly
throughout an infected herd or flock. Control strategies of intense culling of feral
goats at the population level were predicted to allow the disease to persist at low
prevalence, with a small peak corresponding to the annual lambing pulse in sheep.
However, the same level of control (>90% reduction) at the herd level was
predicted to eliminate FMD and allow the safe reintroduction of sheep. Extreme
control that left very small groups (<3 individuals) may be counter productive
because such small groups are likely to join the reintroduced sheep in an effort by
the goats to meet gregarious urges.
The spatial model was more reassuring. It predicted that FMD would die out in a
mixed sheep and feral goat population in less than 90 days because of the low rate
of herd to herd contact and herd to flock contact. For similar environments, the
contingency planning consequences are that an outbreak of FMD introduced into
feral goats from sympatric sheep is likely to be containable by removing all the
sheep, determining the extent and likely range of the feral goats, then removing a
substantial proportion of or eradicating each herd. Feral goats, being relatively
sedentary, are unlikely to spread to adjacent populations and the disease will die
out through lack of contact between herds and populations. Because feral goat
home ranges overlap and are centred on one or two small catchments, a
containment ring of feral goat control, set to encompass the home range of a target
herd and that of adjacent herds, should be adequate to limit spread of FMD.

The primary objective of this study was to determine the species composition of ticks that infest domestic animals in Maputo Province and their geographic distributions. To this end a total of 145 cattle, 129 goats, 132 dogs and 63 dragsamples of the vegetation were examined at 30 localities distributed throughout the province, at each of which the geographic coordinates were recorded and later plotted. A total of 15187 ixodid ticks belonging to 15 species were recovered. These were Amblyomma hebraeum, Haemaphysalis elliptica, Haemaphysalis sp., Hyalomma rufipes, Ixodes cavipalpus, Rhipicephalus (Boophilus) microplus, Rhipicephalus appendiculatus, Rhipicephalus evertsi evertsi, Rhipicephalus kochi, Rhipicephalus longus, Rhipicephalus pravus group, Rhipicephalus sanguineus, Rhipicephalus simus, Rhipicephalus tricuspis and Rhipicephalus turanicus. R. (B.) microplus and A. hebraeum were most abundant on cattle, while H. elliptica was most abundant on dogs. H. elliptica, I. cavipalpus, R. longus and R. turanicus can now be added to the lists of ixodid tick species previously published for Mozambique. The geographic distributions of nine of the 15 tick species were mapped, and A. hebraeum, H. elliptica and R. evertsi evertsi were present throughout the province. No indigenous Rhipicephalus (Boophilus) decoloratus were recovered, whereas the introduced Asian tick, R. (B.) microplus was present in all districts. It would seem that R. (B.) decoloratus has been completely displaced by R. (B.) microplus in Maputo Province. Although R. appendiculatus was recovered at 24 of the 30 localities, it was present at only two of the seven localities in the south of the province. R. sanguineus was present on dogs in the districts of Boane, Naamacha and Manhiça, where the collections were made at the dog owners’ homes. R. simus was present at 27 localities and R. turanicus was collected in the districts of Magude, Boane, Namaacha and Matutuine, in the north, centre and south of the province. Future surveys in Mozambique should focus on determining the extent to which R. (B.) microplus has displaced R. (B.) decoloratus. A further objective of the study was to compare the prevalence of the five major tick species, namely A. hebraeum, R. (B.) microplus, R. appendiculatus, R. evertsi evertsi and R. simus on cattle and goats. It was possible to do this at 21 of the sampling sites, at each of which five cattle and five goats had been examined. These five ticks infested both cattle and goats, but the goats harboured larger numbers of immature ticks and fewer adults of some species, while large numbers of both adult and immature ticks were recovered from cattle. Furthermore, more cattle than goats at more localities were infested with adult ticks of each of the five species. Consideration should be given to including goats in future tick control programmes applied to cattle on the same properties. A total of ten ixodid tick species were recovered from dogs in Maputo Province. Of these H. elliptica, R. sanguineus, R. simus and R. turanicus can be considered major parasites of dogs, while large numbers of immature A. hebraeum and smaller numbers of immature R. appendiculatus infested these animals opportunistically.Dissertation (MSc)--University of Pretoria, 2008.

Full textAbstract:
Feedback and goal-setting interventions were used in two separate studies to reduce residential electricity use in households in Northern Ireland. In Study 1 feedback was provided via a pre-payment keypad electricity meter, and the goal commitment was to reduce electricity use by 20%. Electricity use during a one-month intervention was compared to that during the same period in the previous year. The ten households who received feedback reduced their use by a mean 17.13% (p< .0 I, r = 0.69), and the nine households who signed a goal-setting commitment reduced their use by a mean 7.12% (p < .05, r = .067). Study 2 used wireless energy monitors to provide feedback, in combination with a 20% goal-setting commitment for all participants, but also used alternating orders of presentation of intervention and baseline to explore the longer-term effect of feedback on conservation performance. Group 1 received five months of feedback followed by five months of baseline, Group 2 underwent five months of baseline followed by five months of intervention, and Group 3 experienced alternating two-month periods of intervention and baseline over ten months, using a reversal design. Group 1 saved a mean 9.54% of electricity during the intervention, but Group 2 increased their use by a mean 14.24%. Group 2's increase in electricity use is explained in terms of a potential 'compensation effect', whereby lower level users increase use when given feedback. Group 3 showed a pattern of cumulative reductions over successive interventions, with a mean reduction in electricity use of 33% from the first to the third intervention period. Participants in Group 3 did not show a return to baseline levels of electricity use when the intervention was removed; this was interpreted as supportive of conceptions of feedback as a learning tool, with potential to provide long lasting conservation effects.

Entre los principales impactos y amenazas que sufren hoy las comunidades insulares destacan las bioinvasiones y entre estas sobresalen las de cabras. La mayoría de las islas, reportadas en la literatura, son ecosistemas donde la vegetación evoluciono en ausencia de grandes herbívoros. En la isla de Mallorca se sabe de la presencia ancestral de un ungulado pre-humano endémico, Myotragus balearicus, que hace pensar en los herbívoros como un factor de selección siempre presente para la vegetación de la isla. Su nicho ecológico habría sido ocupado hoy principalmente por dos caprinos, que actualmente comparten hábitat y se hibridan, la Cabra Salvaje Mallorquina y la cabra domestica asilvestrada. La presencia de estas cabras ha generado muchas opiniones sobre su efecto en la vegetación de la isla. Por lo que el objetivo de esta tesis fue caracterizar y comparar la composición botánica de la dieta de la Cabra Salvaje Mallorquina y la cabra doméstica asilvestrada en Mallorca, así como del grado del ramoneo sobre los principales componentes de la vegetación y el uso del hábitat realizado por ambas cabras para indagar sobre posibles diferencias de estructura social y de comportamiento que ayuden a dilucidar el nivel de uso de los recursos, así como encontrar posibles evidencias del cambio climático en la dieta del extinto Myotragus balearicus. El estudio se llevo a cabo en seis zonas de la sierra Tramuntana en Mallorca, donde tres zonas son habitadas por la Cabra Salvaje Mallorquina y tres por la cabra domestica asilvestrada. Se realizaron análisis microhistológicos de heces de cada ecotipo de cabra en primavera, verano e invierno durante dos años, así como la evaluación de disponibilidad e intensidad de ramoneo de las especies mas abundantes de la vegetación. El análisis del comportamiento trófico y de los grupos de ambas cabras se realizo mediante focales en tres estaciones del año. La densidad y el índice estomático de fragmentos de epidermis de Buxus sp. encontrados en coprolitos del extinto Myotragus se compararon con epidermis actuales de Buxus balarica y Buxus semprevirens para detectar una posible manifestación del cambio climático. La dieta de la cabra Salvaje Mallorquina y de la cabra domestica asilvestrada fue muy similar sobretodo en épocas de escases (verano). Por lo que el posible daño sobre la vegetación estaría condicionado a una sobrepoblación de cabras, mas que al ecotipo de cabra. Ambos ecotipos de cabras mostraron un comportamiento en la dieta de carácter selectivo, con claras preferencias y rechazos pero también capaz de adaptarse a la disponibilidad ya que hace uso la mayoría de especies disponibles. Unas pocas especies son ramoneadas intensamente en todos los periodos del año, aunque la intensidad de ramoneo de la mayoría de especies estudiadas se puede considerar como moderada. Se encontraron algunas diferencias en el comportamiento trófico de ambas cabras, sobretodo en el tamaño de los rebaños, lo que sugiere un uso más eficiente de los recursos vegetales en la Cabra Salvaje Mallorquina. La densidad y el índice estomático de B. balearica actual, fue considerablemente menor al encontrado en los coprolitos de Myotragus, lo que podría deberse al incremento de CO2. De este estudio se desprende la importancia de gestionar adecuadamente las poblaciones de ambos tipos de cabras de manera que se asegure la conservación de las especies animales y vegetales.Currently the main impacts and threats to island communities include bioinvasions and standing out the goats between them. Most of the islands reported in the literature, are ecosystems where vegetation evolved in absence of large herbivores. On the island of Mallorca is well known the ancestral presence of a pre-human endemic ungulate, Myotragus balearicus, which suggests that herbivore was a selection factor constantly present to the vegetation in the island. Today, two goats that currently shared habitat and hybridized, have mainly occupied its ecological niche: the Wild Mallorcan Goat and feral domestic goats. The presence of these goats has generated many opinions about its effect on the vegetation of the island. Therefore, the aim of this thesis was to characterize and compare the botanical composition of the diet of the Wild Mallorcan Goat and feral domestic goat in Mallorca. Additionally, the browsing levels on the main components of the vegetation and the habitat use by both goats was evaluated in order to investigate possible differences in their social structure and behavior that help to elucidate the level of resource use and find possible evidences of climate change in the diet of extinct Myotragus balearicus. The study was carried out in six areas of the Sierra Tramuntana in Mallorca; three inhabited by the Wild Mallorcan Goat and three by the feral domestic goats. Microhistological analysis of faeces from each goat ecotype in spring, summer and winter for two years as well as the assessment of availability and browsing intensity of the most abundant species of vegetation were performed. Analysis of the feeding and social behavior in both goat ecotypes was conducted through focal in abovementioned seasons. Stomatal density and index of Buxus sp. epidermis fragments found in coprolites from extinct Myotragus were compared with actual epidermis of Buxus balarica and Buxus semprevirens to detect a possible manifestation of climate change. The diet of the Wild Mallorcan Goat and feral domestic goat was very similar especially in times of scarcity (Summer). Indeed, the possible damage on vegetation would be subject to an overpopulation of goats that goat ecotype itself. Both goat ecotypes showed a selective dietary behavior, with clear preferences and rejections, but also capable to adapt to availability because they use most species available. Few species are heavily browsed in all periods of the year, although the intensity of browsing by almost all studied species can be considered moderate. Some differences in the feeding behavior of the both goat ecotypes were found, especially related with herd size, suggesting a more efficient use of plant resources in the Wild Mallorcan Goat. The current density and stomatal indexes in B. balearica were considerably smaller than those found in Myotragus coprolites, which could be due to increased CO2. This thesis highlights the importance of a properly management of both goat ecotype populations so that ensure the conservation of animal and vegetal species.

Data from 10,238 weekly milk yield records from 388 first lactations of Saanen goats were used to evaluate the persistency of lactation under a random regression model. First, five models were compared (W035, W05, W0565, W068 e W10) generated by modifications of Wilmink function, assuming homogeneity of residual variance along the lactation. The value -0.05 was kept on model W05 while models W035, W0565, W068 e W10 used values -0.035, -0.0565, -0.068 e -0.10, respectively, in replacement to -0.05 value. After choosing the best model, six structures were evaluated for residual variance: homogeneity, two classes, three classes, four classes, five classes and six classes along the lactation. Subsequently, six different measures of persistency of lactation, adapted from those used on dairy cattle, obtained by replacing bovine reference values to goats ones on the expressions. AIC, BIC, ln L criterions and likelihood ratio test (nested models) were used on models evaluation. Model W035 presented the best fit among the evaluated ones. Relating to residual variance, the most indicated by used criterions was the structure of six classes. By presenting less genetic correlation with milk yield until 268 days (0.14), the persistency measure (PS4) obtained by the sum of genetic values, on period from 41st to 240th day of lactation, as deviations of yield at 40 days of lactation may be pointed for genetic evaluations. Because of the low heritability of this measure (0.03), few responses from selection are expected on this herd.
Utilizaram-se 10.238 registros semanais de produção de leite provenientes de 388 primeiras lactações de cabras da raça Saanen na avaliação da persistência da lactação sob modelo de regressão aleatória. Primeiramente, foram comparados cinco modelos (W035, W05, W0565, W068 e W10) gerados a partir de modificações da função de Wilmink, assumindo-se homogeneidade de variância residual ao longo da lactação. No modelo W05, o valor -0,05 foi mantido, enquanto nos modelos W035, W0565, W068 e W10 foram usados os valores -0,035, -0,0565, -0,068 e -0,10, respectivamente, em substituição ao valor -0,05. Escolhido o modelo, foram avaliadas seis estruturas para a variância residual: homogeneidade, duas classes, três classes, quatro classes, cinco classes e seis classes ao longo da lactação. Posteriormente, foram avaliadas seis diferentes medidas da persistência da lactação, que são adaptações de medidas utilizadas em bovinos de leite, obtidas por substituir, nas fórmulas, os valores de referência de bovinos pelos de caprinos. Os critérios AIC, BIC, ln L e teste de razão de verossimilhança (modelos aninhados) foram usados na avaliação dos modelos. O modelo W035 apresentou o melhor ajuste dentre os avaliados. Com relação à variância residual, a estrutura com seis classes ao longo da lactação foi a mais indicada pelos critérios utilizados. Por apresentar menor correlação genética com produção de leite até 268 dias (0,14), a medida de persistência (PS4) obtida pelo somatório dos valores genéticos, no período do 41o ao 240o dia de lactação, como desvios da produção aos 40 dias de lactação deve ser indicada para avaliações genéticas. Em razão da baixa herdabilidade desta medida (0,03), pequenas respostas à seleção são esperadas neste rebanho.

This study was performed with the aim of to evaluate the “in vitro” acaricidal activity of the oil of the seed of andiroba against Boophilus microplus, Rhipicephalus sanguineus and Anocentor nitens; the biological activity of the third stage larvae (L3) of Musca domestica and the activity of the oil of the seed of andiroba on the larval culture of gastrointestinal nematodes of goat and sheep. The acaricidal activity in the related species of tick was carried by means of the engorged females immersion test, using groups of 10 engorged females with three repetitions for treatment; for the test with the third stage larvae (L3) of Musca domestica it had been formed four repetitions with 10 larvae for treatment. Strips of filter paper measuring 8.5 x 1.5cm (L x W) were soaked in 0.3ml of the solutions and controls, and next, they were introduced in test tubes, adding 1.30g of vermiculite, being the tubes closed with absorbent cotton. Daily observations were made for detection of mortality of larvae, formation of pupae and adults emergence. The activity of the oil of andiroba on larval culture of gastrointestinalnematodes was determined by the calculation of the percentages of reduction of infective larvae for gram of faeces, using three repetitions. For each experiment it had been used dilutions of 100%, 50%, 30%, 25% and 10% (T1, T2, T3, T4 and T5 respectively) of the oil of the seed of andiroba, using tween 80 as detergent. Two groups had been formed as controls, one with deionized water and another one with tween 80 + deionized water. For the test of reduction of gastrointestinal infective larvae of nematodes, another group was added as positive control (doramectina). The results showed effectiveness of 100% for all the dilutions tested in the three species of ticks. In the test with L3 of de M. domestica, eight days after the accomplishment of the test, it was observed in the 100% concentration 20.0% of larval mortality and 62.5% of inhibition of emergency of adults, values significantly higher than those got in the other treated groups.In the test of reduction of gastrointestinal infective larvae of nematodes, effective reduction (> 90%) was obtained for 100%, 50% and 30% treatments in goat, and for all the treatments for sheep.
Avaliou-se “in vitro” a atividade acaricida do óleo da semente da andiroba contra Boophilus microplus, Rhipicephalus sanguineus e Anocentor nitens; a atividade biológica do óleo da semente de andiroba em larvas de terceiro estágio (L3) de Musca domestica e a atividade do óleo da semente da andiroba sobre o cultivo de larvas de nematóides gastrintestinais caprinos e ovinos. A atividade acaricida nas referidas espécies de carrapatos foi realizada por meio do teste de imersão de fêmeas ingurgitadas, utilizando-se grupos de 10 fêmeas ingurgitadas com três repetições por tratamento; para o teste com L3 de Musca domestica quatro repetições compostas por 10 larvas de terceiro estágio foram formadas. Tiras de papel filtro medindo 8,5 x 1,5cm (C x L) foram embebidas em 0,3ml das soluções do óleo de andiroba e controles, em seguida, colocadas dentro de tubos de ensaio, acrescentando-se 1,30g de vermiculita, introduzindo-se, então, as 10 larvas e vedando-se com algodão hidrófilo. Fez-se observação diária para detecção de mortalidade de larvas, pupação e emergência de adultos. A atividadedo óleo de andiroba sobre cultivos de L3 de nematóides gastrintestinais foi determinada pelo cálculo dos percentuais de redução de larvas infectantes por gramas de fezes (LPG), utilizando-se três repetições. Para cada experimento empregaram-se diluições de 100%, 50%, 30%, 25% e 10% (T1, T2, T3, T4 e T5 respectivamente) do óleo da semente de andiroba, utilizando-se tween 80 como dispersante. Formaram-se dois grupos controle, um com água destilada e outro com tween 80 + água destilada. Para o teste de redução de larvas infectantes de nematóides gastrintestinais, acrescentou-se um grupo controle positivo (doramectina). Os resultados revelaram eficácia de 100% para todas as diluições testadas nas três espécies de carrapatos. No teste com L3 de Musca domestica, após oito dias da realização do teste, na concentração de 100% obteve-se 20,0% de mortalidade larval e 62,5% de inibição de emergência de adultos, valoressignificativamente superiores aos obtidos nos demais tratamentos. No teste de redução do LPG de nematóides gastrintestinais, os resultados revelaram redução altamente efetiva (> 90%) no número de larvas totais para os tratamentos 100%, 50% e 30% em caprinos e em todos os tratamentos para a espécie ovina.

In this study, the Wood model was adjusted to1069 lactations curve from dairy goats, for three different situations of residual structure. At first, the errors were considered as independent for all lactations, in the second as autoregressives of first order also for all lactations and in the third as independent for lactations that showed no residual autocorrelation and autoregressives of first order for lactations that showed, respectively, according the Durbin- Watson test. These three situations were compared by the percentage of convergence and the average and coefficients of variation of the mean square errors (MSE) and coefficients of determination (R2) adjusted. Subsequently, estimates of the variance components and genetic parameters for total milk yield (MY), for coefficients of the Wood model (a, b and c ) and for milk yield at peak (ymax), time to reach the peak (Tmax) and persistency factor (pers) of each lactation were obtained using the procedure REMLF90 (MISZTAL, 2002), with the objective to determine the influence of residual autocorrelation on heritability (h2) and repeatability (r) estimates and of animals rank according to their breeding values. Two genetic evaluations were made, one for MY with coefficients of the Wood model and other for MY with ymax, tmax e pers. The statistical model included the random effects of animal, permanent environmental and error, the fixed effects of contemporary group (year - season of kidding), number of kids per birth, genetic groups and kidding order, and the days in milk (linear) and age at kidding (linear and quadratic) covariates. In the study of individual fitting of the Wood model to lactation curves differences between the three cases of residual structure were very small, then it was not possible to give a residual structure that results in better fit of the model of Wood. The low values for h2 and r estimates for a, b, c coefficients in this three situations indicated that the gains obtained by selection for the shape of the curve was small. The different residual structures used influence estimates of the parameters h2, r and the correlations between traits. In addition, caused differences in animals rank, based on their breeding values of all traits. Therefore, in applying the Wood model, the correction of errors that are not independent must be done.
Neste estudo o modelo de Wood foi ajustado à 1.069 curvas de lactações de cabras, sob três diferentes situações de estrutura residual. Na primeira, os erros foram considerados como independentes para todas as lactações, na segunda como autoregressivos de primeira ordem também para todas as lactações e na terceira como independentes e autoregressivos de primeira ordem para as lactações que não apresentaram e apresentaram autocorrelação residual, respectivamente, segundo o teste Durbin-Watson. Essas três situações foram comparadas entre si pelos percentuais de convergência, e pelas médias e coeficientes de variação (CV) dos quadrados médios do erros (QME) e dos coeficientes de determinação (R2) ajustados. Posteriormente, as estimativas dos componentes de variância e dos parâmetros genéticos para a produção total de leite (PL), para os coeficientes a , b e c do modelo de Wood e para produção de leite no pico (ymax), tempo para atingir o pico (tmax) e fator de persistência (pers) de cada lactação, foram obtidas utilizando-se o aplicativo REMLF90 (Misztal, 2002), com objetivo de verificar a influência da autocorrelação residual sobre as estimativas de herdabilidade (h2) e repetibilidade (r) e sobre a classificação dos animais de acordo com seus valores genéticos. Foram feitas duas avaliações genéticas multicaracterísticas de PL com a , b e c e PL com ymax, tmax e pers, por meio de um modelo que incluiu como efeitos aleatórios o animal, o ambiente permanente e o resíduo; como efeitos fixos o grupo contemporâneo (anoestação de parto), número de crias por parto, grupos genéticos e ordem de parto e como co- variáveis a duração da lactação (linear) e a idade da cabra ao parto (linear e quadrática). No estudo do ajuste do modelo de Wood às curvas de lactação individuais foram encontradas diferenças muito pequenas entre as três situações de estrutura residual, não sendo possível indicar uma estrutura residual que resulte em melhor ajuste do modelo de Wood. Os baixos valores de h2 e r para os parâmetros a , b e c sob as três situações indicaram que os ganhos obtidos pela seleção para o formato da curva foram pequenos. As diferentes estruturas residuais abordadas influenciaram as estimativas dos parâmetros h2 e r e das correlações entre as características estudadas. Além disso, levaram a diferentes classificações dos animais, baseadas nos valores genéticos de todas as características estudadas. Portanto, ao aplicar o modelo de Wood, a correção dos erros que não forem independentes deverá ser realizada.

The goal of the “Domestic Hot Water Heater Using Air Conditioner (A/C) Waste Heat” design project was to introduce students to designing mechanical systems in the “ETME475-Mechanical Systems Design” course. The design project was assigned to two Mechanical Engineering Technology students as their second design project in the course. Students were asked to do their own literature search and create their own designs. Both of them decided to use a concentric-tube heat exchanger to extract heat from hot refrigerant gas to heat water residing in domestic hot water heater tank. Their literature search led them to some manufacturers. Since delivery time for concentric-tube heat exchanger was too long, we purchased a side-by-side-tube heat exchanger and got it installed on our Heat Pump. Some test runs were conducted to measure the efficiency of the unit and its effect on the Coefficient of Performance (COP) of the Heat Pump when heat pump is operated in A/C mode. Contrary to our expectations, results indicate that, COP values have been reduced by about 22%. Measured efficiency of the unit was about 18%. Students have designed a concentric-tube heat exchanger, turned in their final reports and orally presented their designs to the class.

Full textAbstract:
In early studies addressing national energy/environmental (EE) problems we concluded that co-utilization of domestic fuels can significantly reduce national reliance on imported fuels, mitigate NOx, SOx, CO2 and other undesirable emissions and provide valuable waste disposal services. Co-firing of coal and biomass for steam turbine power generation is a near-term co-utilization approach that can make use of existing facilities with relatively minor modifications. However, co-gasification by providing fuel for more efficient combustion turbines and fuel cells and co-liquification to produce transportation fuels have greater long-term EE potential. The development of optimum thermo-chemical co-conversion systems can be fostered by developing a common systematics for the pyrolysis of biomass and coal. Towards this goal we have used the large data bases from ASTM standard ultimate and proximate analyses for all fuels along natures coalification path from biomass to peat, lignite, bituminous and anthracite coal. With this composite data we find systematics in the weight percentages of carbon, hydrogen, total volatiles, fixed carbon and feedstock HHVs vs the weight percentage of oxygen. To meet the need for knowledge of the volatile constituents we have used sparsely available slow pyrolysis data in the literature and our own data to further develop a plausible semi-empirical model (SEM) that relates feedstock and product compositions. We here extend these analytic correlations to lower temperatures with the help of CCTL measurements of yields from the pyrolysis of rice hulls. We have recently applied this SEM to exam the systematic yields of a short list (SL) of products (five gases and five liquids) vs [O], the weight percentage of oxygen in the feedstock. Here anchored to the rice hull data we use our analytical relationships to estimate the yields of a long list (LL) of products including many organic compounds that are known to be slow pyrolysis products of coals and biomass. These relations are put forth as a heuristic challenge to ourselves and to specialists in biomass and coal pyrolysis to obtain more and better data and to seek improved engineering formulas that are needed to advanced co-utilization technology. Then energy debtor nations could utilize all of their available domestic fuels, including opportunity fuels, to mitigate their national EE problems. These preliminary results point to a path towards the development of a co-utilization science and technology for optimizing feedstock blends in many co-firing, co-gasifying or co-liquifying applications.

The goal of sustainable development through the product innovation is a global challenge that Academia and Industries are addressing. The regulatory pressure and the growing demand of eco-friendly products by consumers are two of its main drivers, especially in the household appliances sector. For this aim, manufactures need to change the design approach in order to extend the boundaries of the benchmark analysis of possible innovations: (i) multi-objective criteria should be taken into account such as the environmental issues, costs, technical performances, etc., and (ii) a life cycle thinking has to be adopted to consider long terms benefits or impacts. However, the literature highlights the lack of structured methods able to support the R&D activity according to these perspectives. For this aim, the present paper provides a systematic approach, which exploits lifecycle and innovation tools to effectively support designers in the development of sustainable solutions in a long term perspective. The proposed approach has been applied in real case study to increase the energy efficiency of a domestic refrigerator. In particular, the insulation module has been redesigned by comparing several alternatives in terms of environmental performances and costs over the product lifespan to effectively evaluate the consistency of the developed eco-innovations.

Fuel cells and photovoltaic cells are two promising technologies for green sustainable societies. Both are technologies that are capable of producing electricity but with different techniques. A solar cell converts light directly into electricity by the photovoltaic effect. On the other hand, a fuel cell converts the chemical energy from the reaction between oxygen and a fuel into electricity and water. The fuel used is hydrogen which can be produced using solar energy. Both devices have different working principles, operation requirements, and efficiencies. However, they share the end goal of producing electricity from a non-fossil clean energy source. The main objective of this work is to investigate whether fuel cells or solar cells are more feasible for domestic use by considering the available technologies and information. The comparison is based on the electricity produced by the two technologies provided the same input of energy from the sun. The research focuses on the electrical output, their efficiencies, and the cost of purchasing, operation, and thus the cost of energy produced from the whole system. A desalination domestic scale system based on Reverse Osmosis (RO) technique was proposed as an application to consume this energy.

Full textAbstract:
The goal of the current research was to evaluate the biological parameters of insects when they were exposed to insecticides for several generations. In the experiments, the adults of the house fly Musca domestica L. were feed with one of two insecticides (chlorfenapyr or fipronil) in each generation. The duration of development stages, fecundity, the weight of larvae, pupa, and adults, as well as the sizes of females and males, were evaluated. The statistical significance of differences in biological parameters was assessed by the non-parametric Kruskal-Wallis and Dunn criteria. The duration of the larva stages lasted 2.2 times more in the fourth generation of chlorfenapyr- and fipronil-exposure strains compared to the control laboratory strain of M. domestica. Increasing the period of preimaginal stages of the insect life cycle can be considered as a sublethal effect of insecticides.

Full textAbstract:
As Developing Nations seek to leverage scarce resources toward the goal of achieving a developed status they must reevaluate past practices and explore available and affordable technologies. Where information and communication infrastructures are weak, use of low-cost, easily distributed technologies have proven effective. Still, many developing nations have failed to incorporate a resource in great abundance, their women, to use these new technologies to greatest advantage. This paper will address the implications of women’s lack of economic and educational parity, and offer examples of how the education of women through the use of information and communication technology can enhance a nation’s gross domestic product (GDP).

Full textAbstract:
The performance of 26 PVT-Systems was analysed and compared in IEA-SHC Task 60. The systems are located in countries with different climatic conditions. The applications range from direct domestic hot water production and heating of public swimming pools to heat pump systems with PVT as the main heat source of the heat pump. The Key Performance Indicators (KPIs) determined for the different PVT solutions give the possibility to compare the systems despite their diversity. The goal was to show the potential of PVT collectors in different fields of application. The results show that the integration of PVT collectors in different kinds of well-dimensioned systems leads to competitive solutions, both from an energy and a financial perspective. Additionally the answers to a survey about control strategies for PVT systems, showing some main problems and possible solutions, are summarised.

Full textAbstract:
Why research Palaeolithic and Mesolithic Scotland? Palaeolithic and Mesolithic archaeology sheds light on the first colonisation and subsequent early inhabitation of Scotland. It is a growing and exciting field where increasing Scottish evidence has been given wider significance in the context of European prehistory. It extends over a long period, which saw great changes, including substantial environmental transformations, and the impact of, and societal response to, climate change. The period as a whole provides the foundation for the human occupation of Scotland and is crucial for understanding prehistoric society, both for Scotland and across North-West Europe. Within the Palaeolithic and Mesolithic periods there are considerable opportunities for pioneering research. Individual projects can still have a substantial impact and there remain opportunities for pioneering discoveries including cemeteries, domestic and other structures, stratified sites, and for exploring the huge evidential potential of water-logged and underwater sites. Palaeolithic and Mesolithic archaeology also stimulates and draws upon exciting multi-disciplinary collaborations. Panel Task and Remit The panel remit was to review critically the current state of knowledge and consider promising areas of future research into the earliest prehistory of Scotland. This was undertaken with a view to improved understanding of all aspects of the colonization and inhabitation of the country by peoples practising a wholly hunter-fisher-gatherer way of life prior to the advent of farming. In so doing, it was recognised as particularly important that both environmental data (including vegetation, fauna, sea level, and landscape work) and cultural change during this period be evaluated. The resultant report, outlines the different areas of research in which archaeologists interested in early prehistory work, and highlights the research topics to which they aspire. The report is structured by theme: history of investigation; reconstruction of the environment; the nature of the archaeological record; methodologies for recreating the past; and finally, the lifestyles of past people – the latter representing both a statement of current knowledge and the ultimate aim for archaeologists; the goal of all the former sections. The document is reinforced by material on-line which provides further detail and resources. The Palaeolithic and Mesolithic panel report of ScARF is intended as a resource to be utilised, built upon, and kept updated, hopefully by those it has helped inspire and inform as well as those who follow in their footsteps. Future Research The main recommendations of the panel report can be summarized under four key headings: Visibility: Due to the considerable length of time over which sites were formed, and the predominant mobility of the population, early prehistoric remains are to be found right across the landscape, although they often survive as ephemeral traces and in low densities. Therefore, all archaeological work should take into account the expectation of Palaeolithic and Mesolithic ScARF Panel Report iv encountering early prehistoric remains. This applies equally to both commercial and research archaeology, and to amateur activity which often makes the initial discovery. This should not be seen as an obstacle, but as a benefit, and not finding such remains should be cause for question. There is no doubt that important evidence of these periods remains unrecognised in private, public, and commercial collections and there is a strong need for backlog evaluation, proper curation and analysis. The inadequate representation of Palaeolithic and Mesolithic information in existing national and local databases must be addressed. Collaboration: Multi-disciplinary, collaborative, and cross- sector approaches must be encouraged – site prospection, prediction, recognition, and contextualisation are key areas to this end. Reconstructing past environments and their chronological frameworks, and exploring submerged and buried landscapes offer existing examples of fruitful, cross-disciplinary work. Palaeolithic and Mesolithic archaeology has an important place within Quaternary science and the potential for deeply buried remains means that geoarchaeology should have a prominent role. Innovation: Research-led projects are currently making a substantial impact across all aspects of Palaeolithic and Mesolithic archaeology; a funding policy that acknowledges risk and promotes the innovation that these periods demand should be encouraged. The exploration of lesser known areas, work on different types of site, new approaches to artefacts, and the application of novel methodologies should all be promoted when engaging with the challenges of early prehistory. Tackling the ‘big questions’: Archaeologists should engage with the big questions of earliest prehistory in Scotland, including the colonisation of new land, how lifestyles in past societies were organized, the effects of and the responses to environmental change, and the transitions to new modes of life. This should be done through a holistic view of the available data, encompassing all the complexities of interpretation and developing competing and testable models. Scottish data can be used to address many of the currently topical research topics in archaeology, and will provide a springboard to a better understanding of early prehistoric life in Scotland and beyond.
