This paper shows a comparative analysis of theoretical model for biogas estimations in landfill sites in order to determine reliability, accuracy and efficiency by comparing results with actual data obtained in-situ. The model from the Environmental Protection Agency (EPA) and the Mexican model were selected to estimate biogas generation in a landfill site located in the State of Mexico, Mexico with 36 wells. Both models are based on a first order equation for degradation of organic matter assuming that the biogas generation reaches its maximum after a period of time and then biogas generation decreases exponentially while the organic fraction of waste is consumed. Measurement in-situ, using a landfill gas analyser (GA5000), resulted in values of percentage concentration of landfill gas (CH4, CO2 and O2) with an average Frequency of 35.44 Hz (1/s) and emissions of methane of 3355.99 m3/hr in contrast with 4885.74 m3/hr from EPA model and 6780.56 m3/hr from Mexican model. The experiment evidenced significant variations in estimations versus actual measurements. Authors discuss the aspects and parameters that cause such variations in order to provide a comprehensive analysis which will help decision makers to base waste management strategies in Mexico on reliable data.

Glucocorticoids play a key role in mediating stress responses in vertebrates. corticosterone （cort） is the main glucocorticoid produced in amphibians, birds, and reptiles, and regulates several metabolic functions. The most common methods for quantifying cort are competitive binding immunoassays： radioimmunoassay （RIA） and enzyme immunoassay （EIA）. RIA has been broadly used since the 1980＇s but it requires radioactivity. Commercial EIA kits permit quantifying hormone levels without radioactivity although the requirement for a larger sample volume may be a strong limitation for measurements involving larval amphibians. Here we used Xenopus laevis tadpoles to compare the performance of three commonly used procedures for determination of cort： RIA on a chloroform extract of whole-body homogenate, EIA on plasma, and EIA on supematant of whole-body homogenate. We treated tadpoles with exogenous cort at 0, 25, 50, and 100 nM. RIA could distinguish between 0 and 25 nM, and EIA on plasma between 0 and 50 nM, whereas whole-body homogenate EIA only detected significant differences between 0 and 100 riM. Each procedure presents advantages and disadvantages regarding sensitivity, the use of radioactivity, sample size, handling time, and economic cost. RIA is preferred when studying small-bodied animals from which blood samples cannot be obtained. When cort level differences are intermediate and blood sampling is possible, EIA on plasma is a good non-radioactive alternative. EIA on whole-body homogenates may be useful to assess qualitative changes in cort levels when considerable differences are expected. Finally, we discuss our findings in the context of previous studies on cort in amphibians [Current Zoology 61 （5）： 835-845, 2015].

The industrial obtainment and manufacturing of food cause high levels of pollution because of the generation of waste byproducts. Over the past few years, there has been a significantly increased interest in preserving, restoring and establishing an ecological balance during food production. Many investigators propose biotechnological solutions to the treatment of industrial wastes, especially waste from the dairy industry. The aim of this review is to present biotechnological approaches to the treatment and utilization of wastes from the dairy industry, specifically for milk whey and also discussed biotechnological methods to reduce environmental pollution and obtain chemical compounds with potential applications in the industry.
