Abstract: a survey on the somatic cell count (scc), fat, protein, lactose and total solids percentages on bulk tank milk samples, from december 1996to july 1998, was used to characterize the milk composition as determined by scc. data of 4785 from the database were classified according to the scc, in four groups (group 1, scc < 500 thousand cells/ml; group 2, 500 < scc < 1.000 thousand cells/ml; group 3, 1.000 < scc < 1.500 thousand cells/ml; group 4, scc > 1.500 thousand cells/ml). a descriptive statistics, analysis of variance and multiple mean tests were applied to the groups. increases on the group classes were associated with increases on concentration and standard deviation and decreases on protein and lactose concentrations. despite of the no significance, the total solids tended to decrease as group classes increase. the bulk tank milk samples with higher scc had greater fat percentages, lower protein and lactose percentages and the same total solids percentages. the significant changes in the milk component contents occur above 1.000.000 cells/ml for fat and 500 thousand cells/ml for protein and lactose. bulk tank groups with greater scc have greater variability in milk component compositions.

Abstract: subclinical mastitis results in the decrease of milk and fat production. this disease is detected using somatic cell counts. the objective of this study was to quantify the relation of somatic cell levels, transformed into linear score (ls), and the production of milk and fat during 305 days of lactation, peak milk production, and the lactation duration time of holstein cattle. data were gathered concerning 147 closed lactations of holstein cows (83 primiparous and 64 multiparous) from a confined herd in the state of s?o paulo, brazil. statistical analyses were performed through the general linear model procedure. the productive characteristics of multiparous, but not primiparous cows, were affected acording to the linear score. an increase in the average linear score during lactation resulted in the decrease of fat and milk production in the 305 days of lactation. the increase in the average linear score at the beginning of the lactation period resulted in a decrease of milk production at the peak of lactation.

Revista Brasileira de Zootecnia , 2000,
Abstract: Foi realizado um levantamento dos dados de contagem de células somáticas (CCS), porcentagens de gordura, proteína, lactose e sólidos totais de amostras de leite de tanques recebidas no período de dezembro de 1996 a julho de 1998, com o objetivo de se caracterizar a composi o do leite segundo sua contagem de células somáticas. Os 4785 dados de análise foram classificados segundo sua CCS, sendo formados quatro grupos (grupo 1, CCS < 500 mil cél./mL; grupo 2, 500 < CCS < 1000 mil cél./mL; grupo 3, 1000 < CCS < 1500 mil cél./mL; grupo 4, CCS > 1.500 mil cél./mL). Aos grupos foram aplicadass técnicas de estatística descritiva, análise de variancia e compara es múltiplas de médias. O aumento da ordem das classes acarretou acréscimo da porcentagem de gordura e dos desvios-padr o e redu o nas porcentagens de proteína e lactose. A concentra o de sólidos totais, apesar de n o-significativa, apresentou tendência de redu o. Concluiu-se que leite de tanques com CCS mais altas apresentaram maior porcentagem de gordura, menor porcentagem de proteína e lactose e igual porcentagem de sólido totais. As mudan as significativas nas concentra es do componentes do leite ocorrem a partir de 1.000.000 cél./mL para gordura e 500 mil cél./mL para proteína e lactose. Grupos de tanques com maiores CCS apresentaram maior variabilidade nas concentra es dos constituintes do leite.

Scientia Agricola , 2001,
Abstract: A mastite subclínica, diagnosticada através da contagem de células somáticas, afeta negativamente a pecuária leiteira diminuindo a produ o de leite e de gordura. Este estudo foi realizado com o objetivo de se quantificar o efeito do nível de células somáticas, transformado para escore linear (EL), sobre a produ o de leite e gordura em 305 dias de lacta o, produ o de leite no pico e dura o da lacta o de bovinos da ra a holandesa. Foram levantadas informa es referentes a 147 lacta es encerradas de vacas da ra a holandesa (83 primíparas e 64 multíparas), de um rebanho confinado do Estado de S o Paulo. As análises estatísticas foram realizadas utilizando-se o procedimento de modelo lineares generalizados. Contrariando a literatura, as características produtivas dos animais primíparos n o sofreram efeito do escore linear. Provavelmente este fato ocorreu devido a quase inexistência de animais primíparos com EL maior que 4,5. O aumento do escore linear médio durante a lacta o levou a diminui o da produ o de leite e gordura em 305 dias de lacta o. O aumento do escore linear médio durante o início da lacta o levou a diminui o da produ o de leite no pico da lacta o.

Also the so-called "social networks" such as Facebook or Twitter.
Multi-Scale Characteristics of Precipitation and Temperature over West Africa Using SMHI-RCA Driven by GCMs under RCP8.5  [PDF]
Abdoulaye Sarr
American Journal of Climate Change (AJCC) , 2017, DOI: 10.4236/ajcc.2017.63024
Abstract: In this paper, we use simulations from the Swedish Meteorological and Hydrological Institute (SMHI) regional climate model (RCM) version 3.5 (SMHI-RCA3.5) following a multi-GCM boundary forcing approach. The model is run at a horizontal resolution of 50 km on the CORDEX-AFRICA domain. Key characteristics of precipitation, mean temperature and its extremes (minimum and maximum temperature) have been investigated over West Africa and on 3 designed sub-domains, the Sahel (SAH), the Senegal-Gambia (SEN) and the Gulf of Guinea (GOG). The analysis covers a historical period 1981-2005 and two future time slices, an intermediate term (IT) 2031-2055 and a fat term (FT) 2071-2095, under the Representative Concentration Pathways 8.5 (RCP8.5). The regional climate model RCA, forced by the reanalysis ERA-Interim, 6 CMIP5 GCMs and their ensemble, reproduces realistically the climatology of precipitation and temperatures over West Africa. Compared to observed datasets GPCP for precipitation and CRU for temperature, the ensemble outperforms both other GCMs and the verification model (ERA-Interim). The major biases in precipitation are the early onset over the Sahel and the little dry season (LDS), from mid-July to mid-September over the Gulf of Guinea, and a few models either overestimate and/or reflect rather poorly. The strong warming in extreme temperatures (minimum and maximum) combined with the drying mainly over Western Sahel (SEN) found in this study will very likely impact notably a vital sector like agriculture, both during the near and far terms.

Abstract: This article deals with the intricate ratification process of the Lisbon Treaty, while focusing on the thorny issues of Euroscepticism and democratic deficit within the European Union in the current institutional context. The study is based on a wide research endeavour, whose purpose has been to encompass multiple points of view on the future of the European Union, seen from the perspective of the Treaty of Lisbon and its reception in all member states. These viewpoints include the ones found in the speciality literature, as well as in the press that published representative articles during the debates on the ratification of the Lisbon Treaty. Useful attempts are made in order to classify the member states of the EU according to various relevant criteria in their attitude germane to the ratification of the Treaty, so as to outline new waves of Euroscepticism, opt-outs and criticism. Apart from an institutional and a legal perspective, this study presents a large number of political, national and even cultural aspects encountered in attitudes and courses of action pertaining to the future of European Construction, seen through the eyes of the reform process carried out by the latest EU major legal document.
Proof Complexity and the Kneser-Lovász Theorem (I)

Computer Science , 2014,
Abstract: We investigate the proof complexity of a class of propositional formulas expressing a combinatorial principle known as the Kneser-Lov\'{a}sz Theorem. This is a family of propositional tautologies, indexed by an nonnegative integer parameter $k$ that generalizes the Pigeonhole Principle (obtained for $k=1$). We show, for all fixed $k$, $2^{\Omega(n)}$ lower bounds on resolution complexity and exponential lower bounds for bounded depth Frege proofs. These results hold even for the more restricted class of formulas encoding Schrijver's strenghtening of the Kneser-Lov\'{a}sz Theorem. On the other hand for the cases $k=2,3$ (for which combinatorial proofs of the Kneser-Lov\'{a}sz Theorem are known) we give polynomial size Frege ($k=2$), respectively extended Frege ($k=3$) proofs. The paper concludes with a brief announcement of the results (presented in subsequent work) on the proof complexity of the general case of the Kneser-Lov\'{a}sz theorem.
