Abstract:
Abstract. The characteristics of ionospheric scintillations at Rajkot in the equatorial anomaly crest region in India are described for the years 1987–1991 by monitoring the 244-MHz transmission from the satellite FLEETSAT. This period covers the ascending phase of solar cycle 22. Scintillations occur predominantly in the pre-midnight period during equinoxes and winter seasons and in the post-midnight period during summer season. During equinoxes and winter, scintillation occurrence increases with solar activity, whilst in summer it is found to decrease with solar activity. Statistically, scintillation occurrence is suppressed by magnetic activity. The characteristics observed during winter and equinoxes are similar to those seen at the equatorial station, Trivandrum. This, coupled with the nature of the post-sunset equatorial F-region drift and h'F variations, supports the view that at the anomaly crest station, scintillations are of equatorial origin during equinox and winter, whilst in summer they may be of mid-latitude type. The variations in scintillation intensity (in dB) with season and solar activity are also reported.

Abstract:
Abstract. The ionosphere is the major error source for the signals of global positioning system (GPS) satellites. In the analysis of GPS measurements, ionospheric error is assumed to be somewhat of a nuisance. The error induced by the ionosphere is proportional to the number of electrons along the line of sight (LOS) from the satellite to receiver and can be determined in order to study the diurnal, seasonal, solar cycle and spatial variations in the ionosphere during quiet and disturbed conditions. In this study, we characterize the diurnal, seasonal and solar cycle variation in observed total electron content (OBS-TEC) and compare the results with the International Reference Ionosphere (IRI-2016) model. We obtained TEC from a dual-frequency GPS receiver located at Birnin Kebbi Federal Polytechnic (BKFP) in northern Nigeria (geographic location: 12.64∘ N, 4.22∘ E; 2.68∘ N dip) for the period 2011–2014. We observed differences between the diurnal variation in OBS-TEC and the IRI-2016 model for all hours of the day except during the post-midnight hours. Slight post-noon peaks in the daytime maximum and post-sunset decrease and enhancement are observed in the diurnal variation in OBS-TEC during the equinoxes. On a seasonal scale, we observed that OBS-TEC values were higher in the equinoxes than the solstices only in 2012. However, in 2011, the September equinox and December solstice recorded a higher magnitude, followed by the March equinox, and the magnitude was lowest in the June solstice. In 2013, the December solstice magnitude was highest, followed by the equinoxes, and it was lowest in the June solstice. In 2014, the March equinox and December solstice magnitudes were higher than the September equinox and June solstice magnitude. The June solstice consistently recorded the lowest values for all the years. OBS-TEC is found to increase from 2011 to 2014, thus revealing solar cycle dependence.

Abstract:
Abstract. The variability of zonal winds and the horizontal wind velocity variance of short period (20–120 min) gravity waves (GWs) in the equatorial mesopause region are studied using medium frequency (MF) radar observations from Pameungpeuk (7.4° S, 107.4° E) during 2004–2010. The zonal winds display a distinct semiannual oscillation (called mesospheric semiannual oscillation, MSAO), with westward winds during equinoxes and eastward winds during solstices. Furthermore, the westward winds during March equinox are larger during 2008 and 2009. The short period GW variance also shows a semiannual oscillation with enhanced activity during equinoxes. A good correlation is observed between the zonal winds and the short period GW variance from 2008–2010, with the winds being westward during the times of enhanced GW activity. Such a correlation, however, is less obvious during 2004–2006. The long period (10–20 h) GW variance, on the other hand, does not show such a correlation throughout the observation period.

Abstract:
Abstract. The study of diurnal and seasonal variations in total electron content (TEC) over Nigeria has been prompted by the recent increase in the number of GPS continuously operating reference stations (CORSs) across Nigeria as well as the reduced costs of microcomputing. The GPS data engaged in this study were recorded in the year 2012 at nine stations in Nigeria located between geomagnetic latitudes – 4.33 and 0.72° N. The GPS data were used to derive GPS TEC, which was analysed for diurnal and seasonal variations. The results obtained were used to produce local GPS TEC maps and bar charts. The derived GPS TEC across all the stations demonstrates consistent minimum diurnal variations during the pre-sunrise hours 04:00 to 06:00 LT, increases with sharp gradient during the sunrise period (∼ 07:00 to 09:00 LT), attains postnoon maximum at about 14:00 LT, and then falls to a minimum just before sunset. Generally, daytime variations are found to be greater than nighttime variations, which range between 0 and 5 TECU. The seasonal variation depicts a semi-annual distribution with higher values (∼ 25–30 TECU) around equinoxes and lower values (∼ 20–25 TECU) around solstices. The December Solstice magnitude is slightly higher than the June Solstice magnitude at all stations, while March Equinox magnitude is also slightly higher than September Equinox magnitude at all stations. Thus, the seasonal variation shows an asymmetry in equinoxes and solstices, with the month of October displaying the highest values of GPS TEC across the latitudes.

Abstract. The temporal variations of the low latitude nighttime spread F (SF) observed by DPS-4 digisonde at low latitude Hainan station (geog. 19.5° N, 109.1° E, dip lat. 9.5° N) during the declining solar cycle 23 from March 2002 to February 2008 are studied. The spread F measured by the digisonde were classified into four types, i.e., frequency SF (FSF), range SF (RSF), mixed SF (MSF), and strong range SF (SSF). The statistical results show that MSF and SSF are the outstanding irregularities in Hainan, MSF mainly occurs during summer and low solar activity years, whereas SSF mainly occurs during equinoxes and high solar activity years. The SSF has a diurnal peak before midnight and usually appears during 20:00–02:00 LT, whereas MSF peaks nearly or after midnight and occurs during 22:00–06:00 LT. The time of maximum occurrence of SSF is later in summer than in equinoxes and this time delay can be caused by the later reversal time of the E×B drift in summer. The SunSpot Number (SSN) dependence of each type SF is different during different season. The FSF is independent of SSN during each season; RSF with SSN is positive relation during equinoxes and summer and is no relationship during the winter; MSF is significant dependence on SSN during the summer and winter, and does not relate to SSN during the equinoxes; SSF is clearly increasing with SSN during equinoxes and summer, while it is independent of SSN during the winter. The occurrence numbers of each type SF and total SF have the same trend, i.e., increasing as Kp increases from 0 to 1, and then decreasing as increasing Kp. The correlation with Kp is negative for RSF, MSF, SSF and total SF, but is vague for the FSF.

Abstract:
Abstract Although the sun crosses the equator 2 times per year at the equinoxes, at times in the past the equatorial insolation has had only one maximum and one minimum throughout the seasonal cycle because of Milankovitch orbital variations. Here a state-of-the-art coupled atmosphere–ocean general circulation model is used to study the effect of such insolation forcing on equatorial surface properties, including air and sea temperature, salinity, winds, and currents. It is shown that the equatorial seasonality is altered according to the insolation with, for example, either maximum sea surface temperature (SST) close to the vernal equinox and minimum SST close to the autumnal equinox or vice versa. The results may have important implications for understanding tropical climate as well as for the interpretation of proxy data collected from equatorial regions.

Abstract:
When were equinoxes first understood? If the notion were as simple as it might seem, it ought not to be difficult to determine; but the controversies around it show that the matter is not so simple. In fact, it is very difficult to establish the equinoxes, and that difficulty led to several revisions of the notion. But with them came a change to the object under discussion changed as well – more profound than one would think given the stability of the term. This article traces the story.

Abstract. Wind data collected by the Maui meteor radar (20.75° N, 156.43° W) are used to study the 8-h tide in the mesosphere and lower thermosphere (MLT) region at a low-latitude station. The data set spans the time interval from 19 May 2002 to 24 May 2007. Our results show that the 8-h tide is a regular and distinct feature over Maui. The meridional component of this wave is significantly larger than the zonal component. The meridional component exhibits a semiannual variation in amplitude, with peaks near the equinoxes, whereas the variation of the zonal component does not show this seasonal characteristic. The strongest wave motions mostly occur in the height range of 92–96 km near spring equinox (March) and at higher altitudes near autumn equinox (October). The vertical variations of 8-h tidal phase at Maui indicate an upward wave energy flux. The vertical wavelengths are ≥54 km in equinox months.

Este trabalho pretende ser um resumo do que na actualidade se debate a nível científico e clínico acerca da fisiopatologia, diagnóstico, tratamento, prognóstico e prevenção de uma patologia muito grave e ainda muito pouco compreendida como é a laminite em equinos. Sendo uma patologia algo frequente e debilitante, com prognóstico de reservado a mau, e embora existam há muitos anos tentativas da comunidade científica em explicar a laminite, de maneira a melhorar o tratamento e a prevenção, estes estudos têm sido muitas vezes contraditórios. Apesar de ter já existido uma grande evolução no estudo desta patologia no entanto o factor desencadeante não foi ainda comprovado cientificamente apesar de existirem algumas teorias a seu respeito. Serão apresentados dois casos clínicos que ocorreram durante o meu período de estágio, com os quais me apercebi não só das dificuldades atrás referidas mas também de outras associadas à clínica de equinos em Portugal, sendo a mais visível a vertente económica.

A Osteoartrite (OA) é a principal causa de claudicação no cavalo de desporto e lazer, sendo uma afecção que tem grandes repercussões económicas. Este trabalho descreve algumas das características importantes da estrutura articular, bem como da sua fisiologia. Define a OA e todas as estruturas envolvidas no seu processo. Os mecanismos fisiopatológicos põem em evidência os factores de risco em causa e que determinam todo o processo de degradação articular. São descritos os vários meios de diagnóstico utilizados, quer os convencionais, quer as recentes técnicas imagiológicas (ressonância magnética, tomografia computadorizada e cintigrafia nuclear) quer ainda os biomarcadores do metabolismo da cartilagem articular e osso. A abordagem terapêutica é diversa incluindo os anti-inflamatórios não esteróides, os corticosteróides, os glicosaminoglicanos polisulfatados, o hialuronato de sódio, o pentosan polisulfato e o ácido tiludrónico, com o objectivo de travar a progressão da doença articular. Também são abordadas novas formas alternativas de tratamento da OA, como a terapia por meio de ondas de choque, a utilização de células estaminais mesenquimatosas e a terapia genética. Este trabalho é complementado pela descrição de dois casos clínicos, onde são abordados o diagnóstico e respectivo tratamento.

It’s physiopathology puts in evidence all the risk factors and all the process of joint degradation associated. Diagnosis methods are mentioned, not only the conventional ones, but also the recent imaging techniques (magnetic resonance imaging, computed tomography and nuclear scintigraphy) and the use of the bone and cartilage biomarkers. Diverse types of treatment are used, as it is the case of non-steroidal anti-inflammatory, corticosteroids, polysulfated glycosaminoglycan, hyaluronan, pentosan polysulfate and acid tiludronic, drugs, achieving to decrease the progression of the joint disease. Also new forms of treatment of the OA are referred as the therapy using shock waves, mesenchymal stem cells and the gene therapy. Two clinical cases are described, where the diagnosis and treatment are boarded.

O presente trabalho constou de três experimentos. O primeiro objetivou verificar a influência de diferentes concentrações de plasma seminal e de dois diluentes na motilidade e na integridade e funcionalidade da membrana plasmática de espermatozóides eqüinos resfriados. Para tanto, foram utilizados 4 garanhões, comprovadamente férteis e em atividade sexual. Imediatamente após a coleta, o sêmen foi avaliado, diluído 1:2 com EDTA-glicose, dividido em oito alíquotas e centrifugado a 600g, por 10 minutos, para remoção do plasma seminal. O pellet de cada alíquota foi ressuspendido com um determinado volume do plasma seminal, previamente removido e acrescido de um determinado volume de um dos dois diluente (leite desnatado UHT ou leite desnatado-glicose) até atingir uma concentração final entre 40 e 50x106 espermatozóides/ml, contendo as seguintes concentrações finais de plasma seminal: 0%, 2,5%, 5% e 10%. Imediatamente após a diluição, o sêmen foi avaliado quanto à motilidade progressiva e total e funcionalidade e integridade da membrana plasmática. A seguir, os oito frascos contendo o sêmen, com um volume aproximado de 12 ml cada, foram resfriados em câmara a +4ºC a uma taxa de resfriamento de 0,3º C/min, sendo o sêmen novamente avaliado às 24, 48 e 72 horas.

Abstract:
Com o objetivo de avaliar o efeito da suplementação com gama-orizanol em equinos submetidos a exercício aeróbio foram utilizados 10 cavalos da raça Puro Sangue Árabe, machos, castrados, com idade média de 35±8,15 meses e peso corporal médio de 375±22,78 kg, ao início do período experimental, divididos em dois lotes de cinco animais cada, denominados grupos \"controle\" e \"gama\". O experimento foi conduzido no Laboratório de Pesquisa em Alimentação e Fisiologia do Exercício de Equinos (LABEQUI), pertencente à FMVZ-USP, no Campus Administrativo de Pirassununga, São Paulo, adotando-se o consumo diário individual de 2% do peso corpóreo, com base na matéria seca, sendo 50% de volumoso composto por feno de gramínea e 50% de concentrado comercial. Em cada refeição, todos os animais receberam 50 mL de óleo vegetal, sendo que apenas o grupo gama recebeu o gamaorizanol (dez gramas diárias). Ambos os grupos foram exercitados em caminhador circular, durante 60 minutos, na velocidade máxima de 12 km/h, cinco vezes por semana. Durante o período experimental de seis meses, os cavalos foram mensalmente avaliados quanto ao ganho de peso, escore de condição corporal, frequência cardíaca e lipídeos plasmáticos (colesterol total e frações HDL-C, VLDL-C, LDL-C; e triglicérides). A cada quarenta e cinco dias foram realizadas mensurações ultrasonográficas da espessura da camada muscular e adiposa do músculo Longissimus dorsi, e da espessura da camada de gordura na região de inserção da cauda. Foi utilizado o delineamento inteiramente casualizado com medidas repetidas no tempo. Em relação ao peso corporal ou às medidas ultrassonográficas não foi observada diferença entre os grupos, porém foi verificada redução do escore corporal, com redução ao longo do tempo (p=0,04) de 10% para o grupo gama quando comparado com o grupo controle (6,5%). A concentração de colesterol total foi maior (p=0,001) para o grupo gama (113,99 mg/dL) do que o grupo controle (108,55 mg/dL). Em relação à frequência cardíaca (FC) foram observados efeitos de tempo para a FC basal (p=0,001), final (p=0,003), e ao final do exercício após 10 (p < 0,001) e 20 (p=0,009) minutos. A FC após 20 minutos também demonstrou interação tempo*tratamento (p=0,05), onde o grupo gama obteve menor média (46,03 bpm) do que o grupo controle (46,21bpm), e ao longo dos 180 dias a média desta variável reduziu em 30% para o grupo gama em relação ao controle (7%). A suplementação com gama-orizanol de equinos submetidos a exercício aeróbio pode proporcionar redução do escore de condição corporal, elevar a concentração de colesterol plasmático e pode melhorar a recuperação da frequência cardíaca após o esforço.
In order to evaluate the effect of supplementation with gamma-oryzanol in horses undergoing aerobic exercise were used ten Purebred Arabian horses, geldings, mean age 35±8.15 months and mean weight of 375±22.78 kg at the beginning of the experimental period, divided into two groups of five animals each, named \"gamma\" and \"control\" groups. The experiment was conducted at the Laboratório de Pesquisa em Alimentação e Fisiologia do Exercício de Equinos (LABEQUI), belonging to FMVZ-USP, at Campus Administrativo de Pirassununga, São Paulo, adopting individual daily consumption of 2% of body weight, based on dry matter, 50% of forage composed of grass hay and 50% commercial concentrate. In each meal, the animals received fifty milliliters of vegetable oil, and only the gamma group received the gamma-oryzanol (ten grams daily). Both groups were trained in electronic walker for sixty minutes at a maximum speed of 12 km/h, five times a week. During the trial period of six months, the horses were evaluated monthly to weight gain, body condition score, and plasma lipids (total cholesterol and HDL-C, VLDL-C, LDL-C, and triglycerides). The every fortyfifth days were performed ultrasonographic measurements of the thickness of muscle and adipose Longissimus dorsi, and the thickness of the fat layer at the insertion of the tail. We obtained heart rates (HR) at baseline, during maximal work (HR peak), final HR and HR at 10 and 20 minutes after the end of the exercise. We used a completely randomized design with repeated measures and significance level was 10 %. In relation to body weight or measure ultrasound there was no difference between the groups, but was observed reduction of body condition score, reducing over time (p=0,04) of 10 % for the gamma group when compared with the control group (6.5 %). The total cholesterol concentration was higher (p=0.001) for the gamma group (113.99 mg/dL) than the control group (108.55 mg/dL). Regarding the heart rate (HR) effects were observed over the time baseline HR (p=0.001), final (p=0.003), and at the end of exercise after 10 (p < 0.001) and 20 (p = 0.009) minutes. The HR after 20 minutes also showed interaction time*treatment (p=0.05) , the gamma group had lower average (46.03 bpm) than the control group (46.21bpm) , and over the 180 days the average this variable reduced by 30 % for the gamma compared to control group (7 %). Supplementation with gamma-oryzanol in horses undergoing aerobic exercise can provide a reduction of body condition score, raising the concentration of plasma cholesterol and can improve heart rate recovery after exercise.

Abstract:
The Gnomon is the oldest object used by man to measure time, manipulated for observations, ancient astronomers could determine time measurement patterns such as solstices and equinoxes. In this perspective, this article aims to show the implementation and construction of an electronic Gnomon using Arduino microcontroller and Light Dependent Resistors (LDR) in order to make the sun's direction available via the internet and store its data for future analysis and pattern comparisons.
