Trial were conducted at 5 farms, on 5 breeds of pigs in itch farm, in a period from 2000 to 2010. To analyzed data, the MME LS model was used to correct FYS and Breed as fixed effect and Sire as random one. Genetic parameters were estimated from half siblings group. Bones had significantly smaller weight in Pietrain pigs compared to all other breeds. Furthermore, daily and life gains at the Pietrain breed were significantly smaller compared to other breeds. Heritability estimates were significantly different for three breeds, higher for bones, higher for meat yield. The pheneotipic and genetic variations were similar for all traits. Economic effect of selection can be analyzed and expected with a positive trend. Genetic correlation showed expected trend. It is possible to use the effect of indirect selection as well.

The objective of the study was to optimize the conditions in a culture medium for the selenium yeild enriched by Saccharomyces sp. III using Plackett-Burman design and Box-Behnken design. The Plackett-Burman multifactorial design was first employed to screen the significant factors in the fermentation for the selenium yeild, and subsequent use of the response surface methodology was further optimized for the selenium yeild by Box-Behnken design. The important factors in the culture medium, identified by the initial screening method of Placket-Burman, were sodium selenite, glucose and the liquid volume. The optimal amounts for maximum selenium yeild were: sodium selenite 15.8 mg/L; glucose 40.2 g/L; the liquid volume 120 mL in 250 mL flask. Using this statistical experimental design, the selenium yeild under optimal condition reached about 1679.32 μg selenium /g dry cell.

Abstract Introduction: The addition of R to dose-dense chemotherapy CHOP and to high-dose chemotherapy seems to improve the outcome of advanced stage DLBCL. Patients and methods: From August 2000 to September 2006, 120 previously untreated patients (pts) <61 years affected by aggressive DLBCL were enrolled into 12 GIMURELL centers. Inclusion criteria were: advanced stage II, III-IV with age-adjusted (aa)-IPI score 2–3 or BM involvement (any aa-IPI score), viral markers negativity. Treatment plan consisted in a dose-dense chemoimmunotherapy R-MegaCEOP (R 375 mg/m2 d1, CTX 1200 mg/m2 + EPI 110 mg/m2 + VCR 1.4 mg/m2 d3 and PDN 40 mg/m2 dd3–7) every 14 days with G-CSF support for 4 courses; pts in CR or PR received two courses of intensified chemotherapy R-MAD (Mitoxantrone 8 mg/m2 + ARA-C 2000 mg/m2/12h + Dexamethasone 4 mg/m2/12h dd1–3 and R 375 mg/m2 d4 and before peripheral blood stem cell harvest as in vivo purging) followed by ASCT with BEAM as conditioning regimen ± IF-RT. All pts received antibacterial and antifungal prophylaxis throughout the whole treatment. In pts with BM and/or CNS risk involvement, 4 IT-MTX 15 mg were planned as intrathecal prophylaxis. Results: All 120 pts were evaluable: median age 47 years (19–60); 65 males and 55 females; 6% were at Low-Intermediate, 52% at Intermediate-High and 42% at High risk according to aa-IPI score; PS ≥2 65%, 27% BM involvement, 48% bulky disease, 80% LDH >normal and stage II/III/IV 8/19/73% respectively. Complete response at the end of treatment was achieved in 98 pts (82%), PR in 5 (4%), 12 (10%) did not respond and 5 (4%) died of toxicity. IF-RT was performed as consolidation of bulky disease or residual disease on 36% of pts. With a median follow-up of 42 months, 4-yr FFS and 4-yr OS rates were: 77% and 80%. In 101 pts (84%), PBSC yeald was good, with a median of 9.7 × 106 cells CD34/kg (range 2.5–56.3). Nineteen pts (16%) were not autografted: 5 because of inadequate PBSC yield, 9 of progression disease and 5 of toxicity. All 101 pts who underwent ASCT achieved a complete hematological engraftment with a median of 9 days (3–27) to neutrophil counts >0.5 × 109/L and a median of 14 days (1–72) to a self-sustaining platelet count >50 × 109/L. Transfusional support was: platelets and red-cell package respectively in 8% and 24% of pts during 4 R-MegaCEOP, 92% and 70% during 2 R-MAD and 96% and 74% during BEAM consolidation. Few severe toxicities (WHO grade 3–4) were reported; most frequent (12%) were infection and mucositis during R-MAD and BEAM phase. Five patients died of toxicity due to: E.coli sepsis in 2 pts respectively after R-MegaCEOP and R-MAD, one of sepsis ndd after R-MAD, one of Staphilococcus pneumonia after R-MAD and one of P.aeruginosa pneumonia after BEAM regimen. There are no secondary MDS or ANLL or solid tumour. Conclusions: This study suggests that Rituximab as adjuvant to dose-dense and high dose chemotherapy with ASCT support is effective and safe in high risk DLBCL.

Full textAbstract:
Yeld is a Scottish/North of England word meaning barren. The practice-based research contradicts binary notions of fertile/unfertile, nature/culture and inside/outside, arguing for a more nuanced entanglement of the human with the non-human animal and the other-than-human environment. The thesis details the productive ‘naturecultural’ relationship between the author and the Badger Stone, a Neolithic cup and ring marked statutory monument on Ilkley Moor. The three key aims of my practice-based research relate to geographical boundaries, the structuring of identity and cultural resistance to issues of power and control. The research tests postcolonial theory as a strategy for reading landscape and investigating geographical boundaries and relates postcolonial theory to phenomenological and other theories about the structuring of identity in relation to performance and place. My research to date has signified a change in emphasis from a definition of postcolonialism as necessarily boundaried and territorial to a potentially new understanding of postcolonialism as signifying a political tactic of resistance to issues of power and control. The primary themes of walking, collecting, mapping and printmaking were the catalyst into performance and land art. Four key performances on the Moor investigated considerations of place in relation to what I term ‘heritage control’ as a strategy for land management and access to scheduled monuments. By intertwining different theoretical ideas and actions, print forms became natural/cultural objects situated somewhere between physical artefacts and ephemeral performance. It is the combination of performance with principles of mapping that form the potentially original contribution to knowledge that this thesis attempts to outline.

Full textAbstract:
[Abstract]: Yield maps provide essential information for the spatial analysis and evaluation of crop production management at a within field level. Technology has been developed to conduct yield mapping in various crops including grain, potatoes and forage, but as yet no technology exists for yield mapping sugar cane. The chopper harvester is the most common form ofmechanical harvester for sugar cane. Therefore, the goal of this research is to develop a yield mapping system for the chopper type sugar cane harvester.After a review, it is proposed that a suitable accuracy goal for the sugar cane mass flow sensor would be ‘less than 5% cumulative measurement error, 95% of the time (2 standard deviations), measured over a 100m2 harvest area’.Existing mass flow sensors for other crops are reviewed.Based on this review four potential techniques are proposed to measure the mass flow rate of sugar cane. These were defined as the chopper power, elevator power and feed roller separation and weigh pad. These weretested simultaneously by placing various sensors on a single harvester and comparing the sensor outputs with the mass flow rate as measured by a weigh truck. In this trial, all techniques offered potential but none produced results close to the accuracy goal. A weighing technique, known as the ‘weigh pad’, offered the most potential for improvement and potential to accurately measure the mass flow rate with a single calibration under all conditions. The weigh pad technique suffered from very small load cell sensitivity to flow rate, drift in baseline readings and susceptibility to mechanical noise/acceleration dynamics.An opportunity arose to install a complete yield mapping system on a harvester within a commercial operation. This opportunity was accepted to assess the potential for applying yield maps to the agronomic management of sugar cane. Because the weigh pad sensor required further development at this stage, chopper and elevator power were used as a measure of mass flow rate. A full yield mapping system was developed. Yield mapping, directed soil sampling and variable rate gypsum application was conducted on a case study field. Economic analysis shows a clear economic benefit when compared with standardmanagement.Analysis is conducted on the weigh pad sensor examining its susceptibility to mechanical noise/acceleration dynamics. Theory is developed to mathematically model the effects of acceleration dynamics on the accuracy of weigh pad sensor. Laboratory bench testing supported the mathematical model. From the theoretical and experimental analysis a number of conclusions are drawn:· The weigh pad should be made as light as possible to minimise the error due todynamic conditions.· Electronic analogue filters should be used to reduce the noise due to externalacceleration.· The weigh pad should be as rigid as possible to maximise its natural frequency.A new weigh pad sensor was designed based on these conclusions. Field trials indicated the effects of external accelerations dynamics were significantly reduced. Baseline drift was then found as the next major factor limiting accuracy. The baseline drift was principally caused by the secondary extractor fan of the harvester inducing a negative pressure on the weighpad. A rubber curtain placed between the weigh pad and the secondary extractor fan reduced the negative force on the weigh pad due to the secondary extractor fan by 74% (from 17 N to 4.4 N). Therefore it is recommended the curtain be used to minimise the impact of the secondary extractor fan on the baseline drift of the weigh pad.A yield mapping system has been developed for the sugar cane chopper harvester incorporating the weigh pad sensor, a ground speed sensor, a DGPS receiver, a yielddisplay/monitor and data logger. Three identical systems have been constructed and installed on three harvesters for the 1998 cane harvest season. The results show sugar cane could be yield mapped using standard yield mapping principles.The level of accuracy being achieved by the yield mapping system is less than 16% error, with 95% confidence, over a measurement area of approximately 1400 m2. Although theaccuracy achieved is not to the desired research goal, yield maps were produced with satisfactory detail to make agronomic management decisions. The reliability of the sugar cane yield mapping system under field condition in a commercial operation was satisfactory. However, two techniques are proposed (“auto-zeroing” and “batch weighing” techniques) to improve the accuracy and reliability of the weigh pad readings during wet or adverseharvesting conditions.After note: At the time of writing the NCEA along with Case Austoft (CNH) were continuing to conduct research and development on the system and are intending to make theyield mapping system available as a standard item on new harvesters and a retrofit unit on existing harvesters in the near future (C. Barret, per. comm. 2001). The proposed “autozeroing” and “batch weighing” techniques are being tested.

Flooding effects mineral composition of pasture grasses, but little is known concerning effects on mineral metabolism and fiber digestibility in animals. Experiments were conducted to investigate effects of flooding and Al-nitrilo-triacetate (Al-NTA) on growth, chemical composition and digestibility of annual ryegrass (Lolium multiflorum, L.). Ryegrass was grown in a greenhouse experiment on Bucks silt loam soil with two soil moisture levels (flooding and 80% field capacity) and two Al rates (0 and 135 mg/kg) as Al-NTA.
Flooding increased Al, Fe, Cu, Ca and fiber and decreased dry matter yield, Mg, K and Zn concentrations. Treatment with 135 mg/kg Al had no effect on Al in plants, but decreased Ca and P concentrations.
Two digestion trials were conducted with meadow voles (Microtus pennsylvanicus) fed forage harvested from the greenhouse experiment. Voles were housed in stainless steel metabolism cages for total collections of feed and feces. A 2-day preliminary, during which voles were fed 100% ryegrass, preceded a 3-day collection period. At the end of the collection period, a blood sample was taken from the animals.
Forage grown under flooding increased apparent absorption of Al, and Ca concentration in urine samples. Apparent absorption of Mg and serum Mg were decreased, and dry matter digestibility tended to decrease.
Grazing forages produced under flooded conditions would increase potential for outbreaks of grass tetany in animals due to reduced Mg intake and absorption. Altered Mg and Ca metabolism appeared related to Al ingestion. Lowered animal performance could result from reduced DM digestibility.Master of Science

Full textAbstract:
Forage kochia (Bassia prostrata, [L.] A. J. Scott) (Synonym = Kochia prostrata [L.] Schrad.) is a perennial semi-shrub that is valued for its forage quality and ability to restore degraded rangeland. However, establishment success of forage kochia plantings in western North America has been erratic. These failures leave the land vulnerable to erosion and invasion of undesirable plants. This research focused on the germination dynamics of forage kochia accessions as it relates to harvest date, planting date, age of seed, and environmental conditions. The effect of planting date, age of seed, and environmental conditions on forage kochia germination was elucidated by planting recently harvested (2010) and year-old, cold-stored seed (2009) monthly, during a four-month period at two locations. Two entries were tested, Immigrant, the standard subspecies virescens cultivar, and an experimental line, Sahsel, of subspecies grisea. Regardless of planting date, location, or age of seed, Sahsel exhibited higher germination percentages than Immigrant. The age of the seed lots used also significantly affected (P<0.05) the germination percentage. Field germination averaged over location and planting date of year-old Immigrant seed was 89.5% less than the current-year fresh seed, and similarly year-old Sahsel seed had 83.6% less germination than current-year seed. Although the two locations were subjected to very different weather patterns, the germination percentage of seeds at each location was not significantly different (P=0.3156). In the year we conducted our study (2011), the germination percentage from planting in February was significantly higher (P<0.05) than January, which was significantly higher (P<0.05) than both March and April. In the final set of trials, different harvest dates were tested by collecting seed in October, November, and December from seven forage kochia accessions. Measurements for total seed yield, 100-seed weight, and germination were collected from seed harvested each month. The month of harvest, accession, and month × accession interaction were significant (P<0.05) for each measurement in the study. Two accessions, Pustsel and KZ6Xsel, matured the earliest and had peak seed production at the October harvest (15.1 and 13.4 g plant-1, respectively). The remaining accessions had maximum yield and viable seed from the November harvest.

L’augmentation des transactions en ligne pose des défis aux entreprises pour gérer les quantités croissantes de données, et leur offre également de nombreuses opportunités avec l’analyse contextuelle des données numériques. Elle modifie considérablement les modes de prise de décision traditionnels et pose des exigences de haut niveau aux décideurs. D’une part, les clients souhaitent partager leurs préférences personnalisées et leurs modes de consommation, et s’attendent à obtenir des produits / services personnalisés et de haute qualité en retour. D’autre part, cette nouvelle tendance conduit également à un besoin d’algorithmes puissants et de meilleurs schémas de représentation des connaissances pour les prestataires de services, ce qui reste un défi pour la plupart des entreprises. Traditionnellement, sans accès aux mégadonnées, de nombreuses entreprises ont tendance à prendre la plupart de leurs décisions importantes sur la base de ce qui est communément appelé «HiPPO» - «the highestpaid person’s opinion». Aujourd’hui confrontées à un environnement à forte intensité de données, elles peuvent utiliser ces énormes quantités d’informations et se tourner vers un mode de décision basé sur les données, ce qui devrait être une clé de leur réussite. Cette thèse vise à étudier les opportunités d’optimisation dans plusieurs industries de services impactées par la révolution numérique. Nos contributions sont à l’intersection de l’analyse commerciale et de la gestion des opérations. Les fournisseurs de services numériques rencontrent plusieurs problèmes opérationnels, qui sont souvent complexifiés par un énorme volume de données, une réponse requise en temps réel, et une échelle de calcul non traitable. Il est donc indispensable d’adapter les modèles d’optimisation déjà connus ou de concevoir de nouvelles approches basées sur les données qui tiennent compte des défis émergents. Nous nous concentrons principalement sur l’optimisation basée sur les données pour les opérations de services numériques. Il s’agira de combiner les quantités croissantes de données avec des méthodologies de programmation mathématique (par exemple, Mixed integer programming, dynamic programming, markov decision process, machine learning) pour concevoir des politiques optimales et prendre des décisions en temps réel. Les résultats doivent aboutir à l’amélioration des performances des prestataires de services. Ce qui suit est un résumé de cette thèse. Dans cette thèse, nous (1) développons des modèles analytiques qui caractérisent le mode de décision stratégique des parties prenantes, (2) concevons des politiques optimales pour soutenir les procédures de prise de décision, et (3) déduisons des conclusions managériales pour aider les directeurs des opérations à prendre de meilleures décisions dans la pratique. Nos résultats théoriques sont testés en pratique. Des prototypes basés sur ces projets ont été partiellement mis en oeuvre dans trois sociétés de services numériques à Bruxelles, Paris et Pékin. Les résultats de nos implémentations ont motivé ces sociétés à nous fournir leurs données pour notre analyse numériqueThis work aims at investigating the optimization opportunities among several typical service industries where the digital revolution occurs. We made a few contributions in the intersection of business analytics and operations management. There are a few operational issues faced by digital service providers, which are often complicated with massive amount of data, real-time response of decisions, and intractable scale of computations. Hence, it becomes extremely important and necessary to tailor the already established optimization models or design new data-driven approaches that account for the emerging challenges occurring in the context of digital service operations. Chapter 2 studies the travel product design problem in an online travel agency by incorporating the diversity of tour packages in order to balance the customer satisfaction and supplier procurement economy-of-scale. Chapter 3 investigates the appointment scheduling problem by considering the geographical visiting distances between sale-visits appointments and the uncertainty in customer preferences. Chapter 4 is motivated by the order assignment operations in online food delivery platforms and the resulting dynamic matching problem, in searching for the appropriate market thickness and the right order driver pairs to establish matches. In the dissertation, we develop analytical models to characterize the strategic decision behavior of stakeholders, design optimal policies to support real-time decision making procedures, and infer managerial insights to help operations managers make better decisions in practice

Resumo: A agricultura é a atividade econômica mais afetada pelo clima. Os fenômenos meteorológicos como a temperatura, precipitação, umidade relativa, velocidade do vento, influenciam tanto na produtividade e qualidade dos produtos agrícolas, quanto nos custos de produção. Uma das ferramentas mais utilizadas para quantificar os efeitos causados pelos fenômenos meteorológicos na produtividade agrícola são os modelos agrometeorológicos. No presente trabalho foi utilizado um modelo agrometeorológico multiplicativo, que se baseia na penalização da produtividade agrícola, em decorrência de fenômenos meteorológicos desfavoráveis ao desenvolvimento da cultura, para a estimativa de safra da soja. O estudo abrangeu um total de 66 municípios nos estados de Goiás, Mato Grosso, Paraná, Rio Grande do Sul e São Paulo. Foram relacionados os municípios que possuíam área plantada de soja superior à 2000 ha, com os municípios que possuíam estações pluviométricas operando entre os anos de 1994à 2000. Utilizou-se mapas pedológicos para diferenciação dos tipos de solos predominantes em cada município, com a finalidade de se obterem informações sobre a capacidade de água disponível no solo (CAD), bem como a média histórica da evapotranspiração potencial (ETP) para o cálculo do balanço hídrico decendial e da evapotranpiração real (ETR). As épocas de semeadura selecionadas foram baseadas no Zoneamento Agroclimático da cultura da soja, elaborado pela Coordenação Nacional do Zoneamento Agrícola. As produtividades estimadas foram comparados com as produtividades reais obtidas através de dados do IBGE. O modelo apresentou correlações significativas entre as produtividades reais e as estimadas,a nível estadual. Os coeficientes de determinação para os estados de Goiás, Mato Grosso, Paraná, Rio Grande do Sul a São Paulo foram respectivamente, 0,5831; 0,6933;0,9162; 0,8504; 0,6426
Abstract: Agriculture is the economic activity more affected by the climate. The meteorologicalphenomena like temperature, precipitation, relative humidity or wind speed have influence in the productivity and agricultural product quality, as well as in the productioncosts.One of the tools more used to quantify the effect caused for the meteorological phenomenain the agricultural productivity is the agrometeorologicalmodel. In the present work an agrometeorologicalmodel for estimate the productivity of the soybean was studied using a total of 66 cities in the states of Goiás, Mato Grosso, Paraná, Rio Grande do Sul and São Paulo. Productivity data of soybean was crossed with rainfall data of pluviometric stations observedbetweenthe years of 1994to the 2000. It was also used pedological maps for differentiation of the types of predominant soil in each city for estimating available water hold capacity of the soil. Historical data was used for estimasting the average of the potential evapotranspiration (ETP) for decendial hidric . balance and evapotranpiration reference (ETR). The selected times for seeding were based on the Agroclimatic Risc Zoning for soybean, elaborated for the National Coordination of the Agricultural Zoning. The calculated produtivities were compared with the data of produtivitiesused by IBGE. The model presented significant correlations between the real produtivities at the leveI of states. The coefficients of determination for the states of Goiás, Mato Grosso, Paraná, Rio Grande do Sul and São Paulo were respectively, 0,5831; 0,6933; 0,9162; 0,8504; 0,6426

Este estudo tem como objetivo avaliar a matéria-prima e sua influência isolada no desempenho do rendimento fermentativo de uma linhagem padrão da levedura CAT-1 testada em 31 meios de cultivos provenientes do processo de fermentação alcoólica da Usina Virgolino de Oliveira – Unidade Catanduva. Os meios foram amostrados e compostos a cada quinzena durante toda as safras 2012 e 2013. O trabalho também tem como finalidade identificar a dinâmica populacional das leveduras do mesmo processo fermentativo, através da diferenciação das linhagens por cariotipagem. As cepas isoladas foram testadas em um meio de cultivo padrão para obtenção das características tecnológicas industriais através da metodologia da Capacidade Fermentativa. Os experimentos de fermentação foram realizados nos laboratórios da Usina Virgolino de Oliveira - Unidade Catanduva em escala reduzida sempre acompanhados de um ensaio padrão utilizando meio de cultivo sintético. O primeiro ponto de estudo consistiu na caracterização da matéria-prima, mosto, e sua capacidade isolada de perturbar o Rendimento Fermentativo. Enquanto que no segundo, onde onze diferentes cepas de levedura foram identificadas ao longo das duas safras, testadas em um mesmo meio de cultivo padrão para obtenção de parâmetros industriais tecnológicos como rendimento em produto (Yp/s), rendimento em célula (Yx/s), Velocidade de consumo do substrato (Vcs), Produtividade (PROD) e Conversão (CONV) e estudada a influência no Rendimento Fermentativo. O terceiro ponto de estudo foi a comparação entre os rendimentos fermentativos obtidos experimentalmente e os rendimentos fermentativos industriais da Planta. O impacto da presença das cepas com maior rendimento em etanol foi estudado em relação aos valores de rendimento fermentativo industrial. Os resultados mostraram diferenças de desempenho da Cepa Padrão na maioria das quinzenas testadas, o que significa que há variação da matéria-prima ao longo da safra e entre as safras capazes de afetar rendimento fermentativo. Diferenças de rendimento também foram observadas entre as onze cepas nativas testadas, porém com oscilações menores e menos consideráveis do que com a matéria-prima. Os resultados obtidos em escala reduzida com base nos balanços de massa se apresentaram valores semelhantes em relação aos números de referência o que sugere que a metodologia usada para avaliar a capacidade fermentativa das cepas e a qualidade da matéria-prima foi adequada. Apesar da forte influência dos fatores estudados, não foi possível afirmar, através destes experimentos, qual deles teve papel determinante no impacto do Rendimento Fermentativo. Isso sugere que outros fatores não estudados neste trabalho estão diretamente relacionados que são capazes de influenciar o Rendimento Fermentativo.
The purpose of this study is to evaluate the sucrose mash and its influence isolated on the performance of the Fermentative Yeld of a standard strain from CAT-1 yeast tested in 31 different culture medium formulation from the Virgolino de Oliveira Plant – Catanduva Unit alcoholic fermentation process. The culture medium formulation were sampled and composed every fortnight during the whole 2012 and 2013 harvest. The work also has as purpose to evaluate the yeasts population dynamics of the same fermentative process, through the differentiation of the strains by karyotyping. The isolated strains were tested in a standard culture medium to obtain the industrial technological characteristics through the Fermentative Capacity methodology. Fermentation experiments were carried out in mill’s laboratories on a reduced scale always accompanied by a standard assay using synthetic culture medium formulation. The first point of study consisted in the characterization of the raw material, sucrose mash, and its isolated capacity to disturb Fermentative Yield. In the second, eleven different strains of yeast identified during the two harvests, they were tested in the same culture medium to obtain industrial technological parameters as Yield in product (Yp/s), Yield in cell (Yx/s), Substrate consumption velocity (Vcs), Productivity (PROD) and Conversion (CONV) and studied their influence on the Fermentative Yield. The third point of study was the comparison between the fermentative yields obtained experimentally and the industrial fermentative yields of the Plant. The impact of the presence of strains with higher Yp/s was studied in relation to industrial fermentation yield values. The results showed differences in performance of the Standard Strain in most of the fortnight tested, which means that there is variation of the raw material during the harvest and between the crops capable of affecting fermentative yield. There were also Yeld difference observed among the eleven native strains tested, but with smaller and less considerable oscillations than with the raw material. The results obtained on a reduced scale based on the mass balances were within the range expected in relation to the reference values, which suggests that the methodology used to evaluate the fermentative capacity of the strains and the quality of the raw material was adequate. Despite the strong influence of the studied factors, it was not possible to prove, through these experiments, which one had a determinant role in the Fermentative Yield impact. This suggests that other factors not studied in this work are directly related that are able to influence Fermentative Yield.

The present study was carried out to determine the proximate composition of green tiger prawn and to select the suitable solvent system for carotenoid extraction. Samples (P. semisulcatus) were purchased from the landsites and transported to the laboratory in an ice box. The whole shrimp were peeled manually, and the residues, consisting head, tail and shells are separated. The moisture content, total lipid, protein, and ash content were quantified using standard methods. Weight of extracted crude of shrimp shells and retention factor (Rf) for the shrimp shell powder were determined using different pure and mixed organic solvents. Moisture content of the fresh shrimp shells was found to be 76.40 ± 0.92 %. In the present study, quantification showed that the shrimp shells are significantly rich in ash content (25.52 ± 0.06 % in dry weight). Significantly (p < 0.05) the highest crude yield of 10.24 ± 0.02 % was obtained from shrimp shells, when the dried shrimp shells powder was dissolved with the mixture of acetone and ethanol (1:1) than the other solvents. The lowest crude yield (2.32 ± 0.01 %) was extracted with ether. The highest Rf was obtained when the shrimp shell crude was dissolved with the mixture of acetone and ethanol (1:1). It can be recommended from our findings that the dried shrimp shells of Peneaus semisulcatus would be directly utilized for formulations of poultry animal feeds and sea cucumber juvenile feeds due to its high ash content. The mixture of the acetone and ethanol (1:1) would be the better choice for obtaining the highest crude yield from the shrimp shells.

Full textAbstract:
Estuaries of the rivers in Bolshoi Sochi district are the most densely populated areas of the Black Sea coastline area in Russian Federation. Study of water runoff and sediment yield in the mouth of the rivers has an important role in applied science, because the frequency of dangerous hydrological processes is very high. Floods and lateral rivers erosion can leads to catastrophic emergencies.
Analysis of hydrological data and physiographic properties of the region help to make several conclusions about water runoff and sediment yield of the region rivers: average annual water and sediment runoff tends to increase, maximum flood discharges increase too.
The mouths of the rivers in Bolshoi Sochi District were classified by natural and anthropogenic factors. In the estuaries district were calculated and ploted on topographic maps flooding areas. Also in the work considered
information of the anthropogenic intervention in the natural environment of the rivers mouths.
