| We present an analysis of time and energy allocation in a day-active caviomorph rodent, the degu, Octodon degus, in central Chile. We quantified components of surface activity in the field on a daily basis in individual degus near the time of the summer solstice, when conditions of heat and aridity were also at a seasonal extreme, in order to answer the following questions. Does the absolute time available for surface activity limit performance? Does the allocation of time and energy for locomotion place a functionally significant limitation on overall energy balance and performance? Degus spent about 2/3 of their above-ground time foraging; they remained stationary about 88 % of the time, walked around slowly about 10 %, and were running rapidly from one... |

| The concept of temporal fit between biophysical systems and institutions has lately received great attention by scholars interested in environmental governance. Although we agree that the concept of temporal fit is a valuable approach for highlighting the temporal challenges of governance systems, we argue that the concept is currently lacking precision with regard to temporal complexity. We build on Barbara Adam’s work on “timescapes” to offer a more nuanced account of temporal fit and misfit. We illustrate the analytical usefulness of our approach by examining the regulation of endocrine-disrupting chemicals (EDCs) within European Union’s Registration, Evaluation, Authorisation, and Restriction of Chemicals... |

| In developed countries the milking collection is done to process in various diary plants situated far away from production areas. There is a problem of cool chain management, which, generally is absent at farm levels. To manage the cool chain in milk transportation system right from farm level it is required that some locally available techniques/materials should be selected and used for milk chilling. The objective of current study is to ascertain mechanism for chilling of milk at farm immediately after milking. The experiments were conducted and the cooling performance was evaluated by noting down the drop in temperature with respect to time using mercury thermometer. The respective regression equation and R2 value were obtained for every run of... |

| BACKGROUND: Nitric oxide (NO) has been shown to be important in sperm function, and the concentration of NO appears to determine these effects. Studies have demonstrated both positive and negative effects of NO on sperm function, but have not been able to provide a clear link between NO concentration and the extent of exposure to NO. To study the relationship between nitric oxide and sperm capacitationin vitro, and to provide a theoretical basis for the use of NO-related preparations in improving sperm motility for in vitro fertilization, we investigated the effects of NO concentration and time duration at these concentrations on in vitro sperm capacitation in both normal and abnormal sperm groups. We manipulated NO concentrations and the time duration of... |

| As milk provides a substantial amount of vitamins and minerals in relation to its energy content, it is considered a nutrient dense food The difference and changes in the nutritional compositions (Protein, fat, carbohydrate, moisture content, ash content, fibre content, magnesium and calcium) of White Fulani, Sokoto Gudali and mixture of the two breeds were investigated before and after autoclaving of milk samples in glass, aluminium and stainless steel containers at various temperatures of 1100C,1210Cand 1300C with autoclaving time of 10minutes, 20 minutes and 30 minutes. The heat treatment was done using MA-DONAX YX-280A Vertical Column Autoclave of 18Litre capacity of pressure of 0.14MPa – 0.165MPa. The results were evaluated using ANOVA at p 0.05.... |

| The behavior of crossbreed cows, milked in the presence or absence of their calves, was analyzed. The trial was conducted on the Dairy Cattle Sector of UESB School of Animal Science in Itapetinga BA Brazil. Twenty crossbreedHolsteinx Gir cows were distributed in a randomized block design with 10 replications for each treatment for the experimental period of 31 days, during lactation. Results were analyzed by nonparametric chi-square test at 5% significance, except the variables time at the milking sector and milk production which were evaluated by analysis of variance and F test at 5% probability. Although cows with the presence of calves during milking had higher reactivity, behavioral activities and more time in the milking sector, milk production was... |

| The soybean has been widely studied due to its constituents and to their application. Authors have pointed out that its composition can vary, with its use frequently taking the form of oil. The oil extraction process, which is in constant application in the market, consists of the use of extraction solvents, with hexane being one of the most used; however the fact that this comes from non-renewable sources has aroused interest in its replacement. As a result, ethanol has been seen as an alternative solvent, despite increasing the cost of the process. This study therefore aims to evaluate the composition of three soybean cultivars planted in the region of Palmas, in the state of Tocantins, Brazil, and to optimise oil extraction from the beans through the... |

| This paper considers the modeling strategies that have been used to incorporate time in revealed and stated preference methods for valuing environmental resources. After reviewing a subset of the economic models for describing time as an input to household production; time in creating habits and persistence in demand for particular services of environmental resources, and time as offering an opportunity for future consumption, the overview suggests that time has been used as a complement in production or consumption to marketed goods in each of these frameworks. The paper suggests two possible alternatives. This structure along with further restrictions to preferences or technology implies that there are other strategies for using revealed preference data... |

| Ecosystem service (ES) trade-offs arise from management choices made by humans, which can change the type, magnitude, and relative mix of services provided by ecosystems. Trade-offs occur when the provision of one ES is reduced as a consequence of increased use of another ES. In some cases, a trade-off may be an explicit choice; but in others, trade-offs arise without premeditation or even awareness that they are taking place. Trade-offs in ES can be classified along three axes: spatial scale, temporal scale, and reversibility. Spatial scale refers to whether the effects of the trade-off are felt locally or at a distant location. Temporal scale refers to whether the effects take place relatively rapidly or slowly. Reversibility expresses the likelihood... |
