A identificação dos fatores causais da interação genótipo x ambiente (GE) e a quantificação destes sobre a variação residual, não explicada pelos efeitos principais, são elementos-chave para o entendimento da adaptação fenotípica. Nos programas de melhoramento há a necessidade da tomada de decisões, como selecionar as linhagens nos ensaios multiambientais (MET). Métodos analíticos vinculados a protocolos de ambientipagem (caracterização ambiental) possibilitam inferências úteis à tomada de decisão, como a identificação de fatores ambientais e genotípicos determinantes da interação GE, a adaptabilidade e a estabilidade contempladas em função de fatores climáticos, edáficos e bióticos, a localização geográfica e o manejo cultural, a perspectiva de avaliação... |

Rotavirus virus-like particles (VLPs) and MS2 bacteriophages were bioaccumulated in bivalve mollusks to evaluate viral persistence in shellfish during depuration and relaying under natural conditions. Using this nonpathogenic surrogate virus, we were able to demonstrate that about 1 log(10) of VLPs was depurated after 1 week in warm seawater (22 degrees C). Phage MS2 was depurated more rapidly (about 2 log(10) in 1 week) than were VLPs, as determined using a single-compartment model and linear regression analysis. After being relayed in the estuary under the influence of the tides, VLPs were detected in oysters for up to 82 days following seeding with high levels of VLPs (concentration range between 10(10) and 10(9) particles per g of pancreatic tissue)... |

Morphometry is a non-invasive method important to assess the size, proportions, and composition of the human body. Because the prediction is an important subject in almost all life sciences, the aim of this research was to find out the cephalofacial variables that may predict the body height. Three cephalofacial variables and the body height were measured on 288 adult male subjects of the Kosovo Albanian population, aged 1835 years old. Using the procedures of regressive analysis we found that cephalofacial variables: head height, head circumferences, face height, significantly may predict body height, and in this way we derived the specific regression equation for estimation of the body height, based on these cephalofacial variables. The predicted body... |

Cranial capacity exerts a close correlation with the volume of the brain. A large body of evidence shows a clear racial variation in cranial dimensions. Therefore detailed knowledge of the population specific data on biometric features of the cranial cavity is important in the study and comparison of the crania of populations from different racial backgrounds, assessing growth and development of an individual and in the diagnosis of any abnormalities of cranial size and shape. Despite its significance, little is known concerning the cranial capacity in Sri Lankans. Hence, the present study was undertaken to establish the cranial capacity in an adult Sri Lankan population. A total of 210 subjects with an age span of 20-23 years were included in the study.... |

Dimensional relationship between body segments and stature has been the focus of scientists for many years. All such studies were based on the fact that body segments exhibit consistent ratios relative to the stature and these ratios are linked to age, gender and race. Racial characters are best defined in the skull. Therefore, prediction of stature from cranial remains is vital in establishing the identity of an unknown individual. Despite its significance, little is known concerning the cranial dimensions in Sri Lankans. Hence, this study was designed to investigate the relationship and to propose a gender and age specific linear regression model between the cranial dimensions and height of an individual. A total of 400 subjects with an age span of 20-23... |

Multiple logistic regression was applied to milk yield and composition data for 632 records of healthy cows and 61 records of ketotic cows in Hokkaido, Japan. The purpose was to diagnose ketosis based on milk yield and composition, simultaneously. The cows were divided into two groups: (1) multiparous, including 314 healthy cows and 45 ketotic cows and (2) primiparous, including 318 healthy cows and 16 ketotic cows, since nutritional status, milk yield and composition are affected by parity. Multiple logistic regression was applied to these groups separately. For multiparous cows, milk yield (kg/day/cow) and protein-to-fat (P/F) ratio in milk were significant factors (P<0.05) for the diagnosis of ketosis. For primiparous cows, lactose content (%), solid... |

The total length distribution of pink cuskeel Genypterus blacodes catches is difficult to obtain. On the contrary, it is easy to have access to the head length distribution. So, the purpose of this study was to obtain a relationship between a certain head measurement and total length to estimate the length distribution of the catches. Individuals were obtained from bottom-trawl surveys between 39°-47°S and the San Jorge Gulf of the Argentine sea. Sets of measurements of total length (LT), maxillar length (Lmax), head length (Lc),orbital length (Lo), preorbital length (Lpo) and head length-total length ratio (r=Lc/LT) by sex were obtained. The total length was estimated with a regression model using the head length as independent variable. No significant... |

Planktonic ciliates were studied in 17 tropical East African lakes of different salinity and trophic status. Oligotrichs (e.g., Strombidium, Strobilidium and Halteria) and scuticociliates (e.g., Cyclidium, Pleuronema, Cristigera), dominated the ciliate communities. Conductivity and trophic status were the most important environmental variables influencing the distribution of ciliate species in East African lakes. Herbivorous oligotrichs were important in oligotrophic and mesotrophic lakes, as they are in temperate and subtropical lakes, but their importance decreased with increasing chlorophyll a concentration and conductivity. On the other hand, the importance of scuticociliates (primarily bacterivores) increased with increasing chlorophyll a and... |

In 1994 Milk Marketing Boards in the UK were disbanded, their role as milk purchasers was taken by more than 100 licensed organisations. It is shown that this change resulted in an increase in the variation between producers' milk price. The majority of dairy farmers sold milk through the Milk Marketing Boards designated successor; a farmer owned co-operative called Milk Marque. In doing so they accepted a 1.5 ppl milk price penalty. It is shown farmers who adopted this strategy did so because of the perceived financial security of Milk Marque, goodwill and support for the principle of co-operative marketing and in an attempt to protect the milk price over the longer-term. The marketing environment changed once again in 2000 when Milk Marque was disbanded.... |

By selecting me time sequence data concerning influencing factors of rural consumer demand in Hebei Province from 2000 to 2010, this paper uses the principal component analysis method in multiplex econometric statistical analysis, constructs the principal component of consumer demand in Hebei Province, conducts regression on the dependent variable of consumer spending per capita in Hebei Province and the principal component of consumer demand so as to get principal component regression, and then conducts quantitative and qualitative analysis on the principal component. The results show that total output value per capita (yuan), employment rate, and income gap, are correlative with rural residents' consumer demand in Hebei Province positively; consumer... |

This paper tests the hypothesis that the net of extraction cost price of a natural resource does not change with volume. The hypothesis is shown to he a consequence of Hotelling’s theory. The tests are performed on equations estimated by a nonparametric regression (ACE), and we show that the usual least squares estimation techniques are not general enough to successfully perform the test. The test rejects the pure form of the Hotelling theory and shows that it is necessary to adjust sale prices for volume sold. |
