This writing is aimed at exploring the models of zakat distribution that might be most applicable in modern era. This is necessary sine the zakat distribution presently doesn’t meet the persons in need maximally. Besides, the unnecessary impacts of zakat sometimes occur such as creating envy and quarreling among the people. Zakat can be distributed in consumptive and productive models. Consumptive models is a model in which zakat is directly give to the people to consume. In the productive models, zakat is distributed in such a way that zakat not is directly consumed at once but it is given to the people for production activity. Productive models involve In Kind, Revolving Fund (al-qard al-hasan), and mudarabah system. In kind system, zakat is distributed in the forms of production equipments. People use those equipment for productive activities so they can do business for their life. In revolving fund (al-qard al-hasan) system, zakat is given similar the the system in al-qard al- hasan, but and quarreling the profit of the business is shared with the zakat management board.

Bovine milk production is carried out in complex productive systems that require constant monitoring of the factors that question them. Likewise, the sector needs to understand the stagnation of annual production at the national level, characterized by a drop in the number of establishments and herds, and a progressive productive efficiency. This entails the study of the determinants of both the economic (EP) and productive (PP) performance of the establishments, what could allow them to improve their competitiveness and, together with other exogenous factors, collaborate to overcome this prolonged stage of productive stability. Starting from a typology of dairy farms in the Pampas Region, the behavior of variables (profitability, cost of production and productivity of the land) and their interrelationship are analyzed. Finally, flexible econometric models that approximate the estimation of the economic and productive performance of the systems under study are formed and analyzed, based on factors that may be decisive for their evolution. The best models resulted from those that used synthetic variables (principal components) as inputs, compared to those that made us and selection of system-specific variables, correcting problems of multicollinearity. The use of instrumental variables could contribute to the resolution of the multicausality present among the factors of the models analyzed.

Purpose As economies with high economic complexity and productive capabilities may easily adapt their productive structure due to product differentiation and innovation, the central variable of competitiveness for these countries is the product quality, not price. On the other hand, the price can be an important determinant of less complex countries, and hence, real exchange rate (RER) misalignments may have long-term impacts. This paper aims to empirically assess variations in the magnitude of the impact in RER misalignments on output growth subject to countries’ economic complexity. Design/methodology/approach The estimation technique used is the generalized method of moments-System estimator as this method is robust to reverse causality. Heterogeneous regressions using interaction models are undertaken to analyze to what extend promoting economic complexity can reduce price competitiveness dependence and allow countries to grow faster without relying on cost competitiveness. Findings Estimates show that economic complexity (which measures technological and productive capabilities) determines cross-country differences regarding the effects of RER misalignments on countries’ long-term growth rates. The results suggest that exchange rate devaluations may not be effective for countries at the top end of the technological ladder while an overvalued RER may damage the long-term growth rate of countries with low levels of economic complexity. Originality/value This paper contributes to the literature by empirically investigating the impact of RER misalignments in countries with distinct technological and productive capabilities based on the recent developments of countries’ economic complexity analysis. It investigates whether more diversified and complex economies are less sensitive to RER misalignments as they can adapt their production, undertake other tasks, create new products and increase the quality of products they produce. Less complex economies, on the other hand, are less capable of innovating because it demands productive capabilities they do not have, and hence, they are more dependent on their current export basket.

Texto completoResumen
Silvopastoral systems can become a development tool, being a form of production where livestock and forestry activities are integrated in the same space. Although forestry activity in Uruguay has evolved steadily with foreign investment, integration with livestock activity has been gradual; the productive and economic aspects and the forms of integration have been scarcely studied. The study of the best forms of integration in the same space can improve competitiveness aspects of both areas. Based on the 2011 agricultural census, a grouping is made that results in four livestock groups and three forestry groups. The use of resources and the productive and social structure are contrasted. Livestock farms forest 21% of the area, with different productive strategies. In a second work, a long-term multi-criteria decision model is structured, taking into account the preferences of a sample of livestock producers. This results in three production and environmental models with results based on the goals to prioritize. When livestock production is prioritized, the best returns from this activity are obtained with the worst results in the environmental goal of carbon balance. The environmental criterion must be considered at higher hierarchical levels in order to achieve positive balance values. This also allows quantifying distances to obtain integrated and sustainable production models. Proposed models and their results can contribute to the quantification of the productive and environmental conflicts and to understanding the advantages and disadvantages of the different integration models, in long term. The future comprehensive development of both activities depends on the knowledge generated about improving the competitiveness of integrated productions. Therefore, this study attempts a contribution that allows identifying and evaluating the different integration models.

Texto completoResumen
Nature-based solutions, principally diverse systems, are increasingly being promoted as the solution to future food production as they are perceived to be more productive, resilient and ecologically based. This ‘paradigm of in-field diversity’ approach is inciting a growing perception that monocultures, the source of most global food production, are ecologically dysfunctional and highly vulnerable to diseases and pests. Our perspective paper clearly shows that natural monodominant vegetation is common in nature and that the ancestral species of major cereals including wheat, barley and rice grew in monocultures maintained by disturbances such as fire or flood. Early farmers mimicked these ecological stresses during field management, favouring annual monodominant crops. We also present well-supported evidence that cereal monocultures are an ancient method of farming founded in the origins of agriculture and that modern plant breeding generates and supports monoculture crops that are inherently genetically diverse and usually resistant to prevailing diseases and pests. Until research has been done on the ecology, agronomy and management of diverse nature-based solutions to future agriculture, the scarce funding to agricultural research for future food production is better targeted at improving monoculture agriculture to be more efficient, productive, resilient and environmentally benign. Monoculture agriculture, particularly for cereals, is a proven natural model for future food production.

In recent years, research on modeling in both the philosophy of science and the social studies of science and technology has undergone an acute transformation. Philosophers and social scientists have begun to realize that science, in the words of Carrier and Nordmann, has increasingly shifted its focus from “epistemic or truth-oriented” research to “application-dominated” research. “Science is viewed today as an essentially practical endeavor” (Carrier and Nordmann 2011, 1) and should be considered in the context of its application. In accordance with this re-orienting of science, research on modeling has also changed. Still considering models as genuinely scientific tools, philosophers and social scientists promoted the “practice turn” that suggests a sharper focus on pragmatic issues and the performative and productive role of modeling. Application of models for the resolution of practice-related problems is viewed as an extension of science.

Introduction. The article deals with mathematical models of two main classes of processes in stochastic productive systems. For a multistage system, conditions of belonging to a “just-in-time” class or a class with infinite support of the time distribution function for productive operations are determined. Materials and Methods. Descriptions and investigations of models are carried out by trajectory (martingale) methods. For “just-in-time” systems and multistage stochastic productive systems, terms and methods of random walks in a random environment and birth and death processes are used. The results are formulated as descriptions of intensity characteristics of equalizers of point counting processes. Results. Two theorems are given and proved; they justify the proposed classification of the mathematical models of productive systems. The criteria of the belonging of the stochastic productive system to the class “just-in-time” are given. A theorem on the incompatibility of groups of “just-in-time” systems and systems infinite support of the time distribution for operations is proved. Discussion and Conclusion. The results show the feasibility of analyzing stochastic productive systems by martingale methods. The descriptions of terms of intensities of the equalizers time of productive processes admit generalization.

Texto completoResumen
Growth and yield models of silviculture applied to four site indices have been drawn up. The data were obtained in 72 plots, installed in 1965 in man made stands of Pinus halepensis Mill., and inventoried in 1965, 1975, 1980, 1988 y 1999. The site index was defined as the top height at age 80 and models were adjusted using the Richards function, obtaining four site qualities: 20, 17, 14 and 11. Following this, silvicultural production models, including two different thinning regimes, were developed for the two higher site qualities sites, with more productive interest (20 and 17) using a simulation with the Hart-Becking rate. For 11 and 14 site quality, only one moderate thinning regime was developed, bearing in mind their most important protection value.

Texto completoResumen
Studies on growth models for productive character of sunn hemp are important to know the behavior of the culture. Therefore, the objective of this research was to adjust non-linear models, Gompertz and Logistic, in the description of productive traits of sunn hemp in two sowing periods. Two uniformity trials were performed. The evaluations began on October the 29th 2014 and December the 16th 2014, totaling 94 and 76 evaluation days for periods 1 and 2, respectively. After the emergence of the seeds of sunn hemp, for first period from 7 days after sowing, and from 2 to 13 days after sowing, on each day, they were collected randomly four plants. The traits: fresh matter leaf, stem, root, shoot, and total, and dry matter leaf, stem, root, shoot, and total. For both models the confidence interval was calculated of parameters a, b and c. The adjustment quality of the Gompertz and Logistic models was verified by the determination coefficient, the Akaike information criteria, residual standard deviation, mean absolute deviation, mean absolute percentage error and mean prediction error. The Gompertz model when compared between the sowing periods through the confidence interval of the parameters, for the productive traits, differs. The same result was found for the Logistic model. The growth models of Gompertz and Logistic presented good adjustment quality.

This research focuses on the productive waqf model in Islamic Boarding School Darunnajah and its impact on the development of educational institutions. Islamic Boarding School Darunnajah, as one of the leading Islamic educational institutions in Indonesia, has adopted various productive waqf models to improve its financial sustainability and infrastructure development. This research aims to analyze the various productive waqf models implemented in Islamic Boarding School Darunnajah, evaluate their effectiveness in supporting the sustainability and improvement of education quality, and formulate recommendations for further development. Using a qualitative approach, data was collected through interviews with Islamic Boarding School managers, field observations, and analysis of relevant documents. The results show that Islamic Boarding School Darunnajah has successfully implemented various productive waqf models, including agricultural land management, commercial property, and financial investment. These models have contributed significantly to increasing the Islamic Boarding School’s income and supporting the development of various educational programs. Based on the findings, this study recommends measures to improve the implementation of productive waqf in Islamic Boarding School Darunnajah, including increased cooperation with the government and the private sector, the development of training programs for Islamic Boarding School managers, and the establishment of strategic partnerships with financial and investment institutions. As such, this study contributes to the understanding of productive waqf practices in Islamic Boarding Schools and offers valuable insights for other Islamic educational institutions interested in developing similar models. The practical implications of this research may help in improving the financial sustainability and quality of education in Islamic Boarding School as well as other Islamic educational institutions in Indonesia.

Texto completoResumen
The implementation of productive arrangements, similar to clusters, in Brazil, has led to the structuring of Local Productive Arrangements (APL). APLs are territorial agglomerations of economic, political, and social agents focused on a specific spectrum of economic activities. The proper structuring of these productive arrangements to incorporate technologies impacts the capacity for transformation and sustainability of the APL, fostering beneficial outcomes on local development and the socio-economic conditions of the territory. Based on the analysis of various models that have been compared by the Sábato´s Triangle and the Technology Habitat Circuit, it is possible to propose a structure of actors/vertices, factors, constructs, and indicators with a view to developing guidelines for the construction of behavioral models of APLs. These models should simulate the dynamic behavior of the arrangement for various compositions, multivariate stimuli, and regional scenarios, allowing for testing proposals aimed at supporting and promoting productive systems.

Materials 16, no. 8 (2023): 3220. http://dx.doi.org/10.3390/ma16083220.
Texto completoResumen
Considering the continuous increase in production costs and resource optimization, more than a strategic objective has become imperative in the copper mining industry. In the search to improve the efficiency in the use of resources, the present work develops models of a semi-autogenous grinding (SAG) mill using statistical analysis and machine learning (ML) techniques (regression, decision trees, and artificial neural networks). The hypotheses studied aim to improve the process’s productive indicators, such as production and energy consumption. The simulation of the digital model captures an increase in production of 4.42% as a function of mineral fragmentation, while there is potential to increase production by decreasing the mill rotational speed, which has a decrease in energy consumption of 7.62% for all linear age configurations. Considering the performance of machine learning in the adjustment of complex models such as SAG grinding, the application of these tools in the mineral processing industry has the potential to increase the efficiency of these processes, either by improving production indicators or by saving energy consumption. Finally, the incorporation of these techniques in the aggregate management of processes such as the Mine to Mill paradigm, or the development of models that consider the uncertainty of the explanatory variables, could further increase the performance of productive indicators at the industrial scale.

Texto completoResumen
The happy-productive worker thesis (HPWT) assumes that happy employees perform better. Given the relevance of teams and work-units in organizations, our aim is to analyze the state of the art on happy-productive work-units (HPWU) through a systematic review and integrate existing research on different collective well-being constructs and collective performance. Research on HPWU (30 studies, 2001–2018) has developed through different constructs of well-being (hedonic: team satisfaction, group affect; and eudaimonic: team engagement) and diverse operationalizations of performance (self-rated team performance, leader-rated team performance, customers’ satisfaction, and objective indicators), thus creating a disintegrated body of knowledge about HPWU. The theoretical frameworks to explain the HPWU relationship are attitude–behavior models, broaden-and-build theory, and the job-demands-resources model. Research models include a variety of antecedents, mediators, and moderating third variables. Most studies are cross-sectional, all propose a causal happy–productive relationship (not the reverse), and generally find positive significant relationships. Scarce but interesting time-lagged evidence supports a causal chain in which collective well-being leads to team performance (organizational citizenship behavior or team creativity), which then leads to objective work-unit performance. To conclude, we identify common issues and challenges across the studies on HPWU, and set out an agenda for future research.

Texto completoResumen
The production ?congestion? phenomenon is widespread in reality although few models nowadays consider its influences. In this study, production congestion is introduced into an environmental efficiency evaluation model and a new data envelopment analysis model that considers both production congestion and undesirable output is established so as to measure environmental efficiency evaluation effectively. On this basis, we divide technological change into productive technological change and energy-savings emission reduction technological change to establish their influences on the congestion phenomenon. The results show that productive technological change cannot relieve the degree of congestion while green technology change that stimulates environmental efficiency improvement can greatly alleviate situations of congestion.

The paper attempts to reveal the most popular word–formation patterns in modern English. The authors make a strong case for pragmatic conditioning of new words. They see the study of the English–speaking community from the perspective of new words as their main goal. The authors’ hypothesis is that these new lexical units direct social actions and allow to forecast most probably the vectors of development of social culture. The paper identifies the major linguistic mechanisms of forming new words. The practical application of the research is that the paper reflects those fragments of social reality which already exist in the language but are not in dictionaries yet. In addition, awareness of new trends in word–formation and its models helps understand new words.

The paper considers the technological cycles of obtaining wax models in automatic molds, in manual molds and by the additive method. The cyclograms of the work of the site for obtaining model blocks consisting of wax models are shown. The dependences of the duration of time cycles for the considered methods of obtaining wax models are presented. It is revealed that the production of wax models in automatic molds is the most productive method, however, this method has the longest cycle of technological preparation of production. The production of wax models in manual molds has a cycle duration comparable to the previous method of technological preparation of production, however, the cycle duration of obtaining wax models for this method is longer. The additive method makes it possible to produce products with a minimum duration of the pre-production cycle. The main operations of manufacturing wax models by the methods under consideration are revealed. The influence of the stability coefficient of operations on the work organization of the site for production wax models is analyzed.

Abstract Pig survival is an economically important trait with animal welfare implications. Although survival is highly affected by the environment, previous studies reported genetic variability of this trait, indicating the opportunity for improvement through selection. Genomic information is currently included in the major commercial pig breeding programs, which can be incorporated by single-step genomic BLUP (ssGBLUP). The objectives of this study were to: 1) estimate (co)variance components for farrowing, lactation, nursery, and finishing survival; and 2) compare the individual breeding value accuracies obtained using traditional pedigree-based BLUP (BLUP) and ssGBLUP methods. Individual survival records were collected for a crossbred pig population, and two-trait threshold models, which included maternal effects, were used for (co)variance components estimation. Direct and maternal breeding values were estimated using BLUP and ssGBLUP methods, and individual accuracies were obtained based on posterior standard deviation. Heritabilities for the four survival phases were low, ranging from 0.04 to 0.12. Pre-weaning survival was controlled by dam and piglet additive gene effects. The additive direct and maternal components were equally important at farrowing, whereas the piglet’s own genetic merit was the most expressive during lactation. Common environment estimates were higher than maternal genetic effects, indicating early life experiences related to the sow, but independent of the maternal genetic component. Nursery and finishing survival showed the same or higher heritabilities compared to pre-weaning stages. The genetic correlation between the pre-weaning phases was high (0.68), whereas the correlation between the post-weaning measurements was moderate (0.42). The incorporation of genomic information through ssGBLUP increased the individual accuracy, on average, from 0.36 to 0.41 for direct and from 0.29 to 0.37 for maternal effects compared to BLUP. Although the heritabilities for survival in different productive stages are low, genetic gains can be obtained, given that breeding values benefit from the inclusion of genomic information.

Texto completoResumen
The paper is positioned in the emerging debate on the technological change brought about by the Fourth Industrial Revolution, often referred to as Industry 4.0. Our analysis is at the local, sub-national level. The aim is to explore what drivers and barriers local productive systems might face when seeking to embark on transitions that reconcile smart, equitable, and sustainable priorities, under enhanced models called Industry 4.0+. The novelty of the paper is to develop such models by designing a conceptual framework that juxtaposes the drivers and the barriers of sustainability transitions with local productive systems. This novel framework suggests possible pathways that local productive systems can initiate to achieve more equitable and green outcomes for their economy and society by directing the development of digital-related solutions.

Abstract. The aim in this study was to estimate variance components and heritability of different longevity measures related to productive life and survival at a specified age, using linear and threshold models, to specify the more appropriate measure to express longevity in Brazilian Holstein cows. Production and reproduction records of Holstein cows were collected from 1991 to 2010, for cows born between 1987 and 2006. Variance components were obtained by restricted maximum likelihood (REML) for measures of productive life and a Bayesian analysis for survival measures. The heritability estimates for longevity measures ranged from 0.06 to 0.09, using the linear model and from 0.05 to 0.18 for traits using the threshold model. This suggests an inexpressive genetic gain using selection for these traits, whereas improvements in environmental factors which affect these animals may lead to greater phenotypic gains. Survival up to 48 months from first calving was the measureing point defined as the most appropriate to be included in future official genetic evaluations of Holstein cattle in Brazil.

Purpose. The aim of the article is to develop dynamic models of the economy taking into account the utilization of industrial and non-industrial pollution products and the control of environmental pollution by unused residues of pollution products. Methodology of research. The following general scientific methods were used in the research process: method of theoretical generalization – for substantiation of theoretical bases and conceptual approaches to revealing the essence of processes of ecological and economic interaction, system approach – for research of economy as integral ecological and economic system, method of mathematical modelling – for formalization of differential models economic dynamics of a single-sector economy, methods of analysis and generalization – to study the parameters of parameterization and modification of models, as well as their practical application. Findings. The result of the work is the developed differential models of ecological and economic dynamics of a one-sector economy, in which the production of basic aggregate products, utilization of industrial waste and pollution products of the non-productive sphere are carried out, and environmental pollution processes are controlled. The dynamics of economic systems reproduced by the models is described in the spaces of social and economic and environmental variables, which include liquid savings of production owners and workers employed in these industries, the price of basic aggregate products, the tariff for pollution emissions and the volume of pollution products unutilized by producers and nature. The models allow extensions and modifications that take into account their applied orientation and the possibility of practical application. Originality. The proposed models formalize ecological and economic dynamics in the conditions of social and economic clustering of society and allow balancing the ecological and social aspects of the economy under study. Practical value. The developed models can be used as a tool for a qualitative and a quantitative analyses of the trajectories of ecological economy both at the regional level and at the macro level, its separate states that can be steady or unstable, low-productive or highly productive which allows to estimate a level of greening the economy and its conformity to ecological standards, etc. and to form thorough expert-analytical base to support appropriate management decisions. Key words: One-sector economy, ecological and economic dynamics, utilization, environmental pollution, model, modelling.

This research examines different productive waqf management models in Indonesia. The study used a qualitative approach, focusing on literature. The findings revealed that the most commonly-implemented productive waqf management model was the productive investment one, which involved land and building rentals. In second place was the profit-sharing financing model, which included collaborations with third parties such as cooperatives, outsourcers, and other institutions. The study also identified the social infrastructure development model, by which buildings such as schools and places of worship were built. The variations in productive waqf management models in Indonesia, as found in this study, were still relatively low when compared to the strategic productive waqf land categorization compiled by the Directorate of Waqf Empowerment. This highlights the need for the Indonesian Waqf Board to develop strategies to increase the ratio of productive waqf at national and sub-national levels, which will eventually lead to the rise of the National Waqf Index.

SUMMARY Data at admission and at surgery were collected on 458 cows with right displacement of the abomasum or abomasal volvulus, to derive multiple logistic regression models for predicting postsurgical outcome (productive, salvaged, or terminal). The derived models contained few and easily obtained variables. The weight associated with each variable was determined objectively. Three admission variables (heart rate, base excess, and plasma chloride concentration), and 5 surgical variables (heart rate, base excess, diagnosis, method of decompression used, and appearance of abomasal serosa) were used in the final models. Predicted outcomes that used the admission and surgical models were closely related with actual outcomes. Total correct classification for satisfactory (productive) versus unsatisfactory outcome (salvaged and terminal) was 78.2% for the admission model and 82.7% for the surgical model. Combining data on cows with productive and salvaged outcomes as satisfactory outcome, and terminal as unsatisfactory outcome, total correct classification was 90.7% for the admission model and 93.2% for the surgical model. Using predicted probabilities, the market value of productive and salvaged cows, and the medical and surgical costs, one can calculate the expected economic value of each outcome. Treatment can be justified if the sum of the expected value of productive and salvaged outcome exceeds the sum of the medical and surgical costs and the expected salvaged value of the cow that was not treated surgically.

Making mathematical models involves translating real-life situations into mathematical expressions. This research, conducted in three Bandung schools with 93 students, focuses on iconic and symbolic mathematical models. Findings reveal that students' abilities using these models are below the expected minimum, with symbolic models being more dominant. The score difference may be influenced by the teacher's role, students' experiences, individual abilities, and specific contexts favoring visual understanding. Students face challenges in making mathematical models, including a lack of comprehensive understanding, difficulty identifying variables, creating context-free models, and struggling with relevant visualizations. Additionally, they encounter issues using formulas and interpreting mathematical results when answering questions. In the validation stage, adjusting temporary results to real situations poses challenges. Internal factors contributing to difficulties include a lack of interest, critical limitations, and low self-confidence. External factors like a limited practical experience in making models also play a role. A holistic solution addressing both internal and external factors is essential for students to overcome challenges and enhance their ability to create mathematical models from real-world contexts. The recommended role of the productive struggle learning approach is crucial in assisting students in achieving the expected milestones.

The production of hybrid maize seeds at the field level can be done by farmers, with the main constraints being limited human resources and capital. For economic recovery during Covid-19 in 2020, the Gunung Mas district government launched a "Cash labor-intensive program" to the community. One of the groups, Sei Kurun farmer group, used it for an innovative and productive hybrid maize seed business. The goal is to grow group as breeder of hybrid maize seed, and empower farmers in a productive and sustainable manner. The method applied is in the form of cooperation and assistance between farmer groups, the Agriculture Service as a partner and prospective buyer of the seeds produced, and AIAT of Central Kalimantan as a companion for the application of technology. The results showed that cash funds for JH 37 hybrid maize seeds can be implemented on 3 hectares, and have produced 1.5 tons of F1 hybrid seeds, which are then sold through the District Agriculture Office program. with a profit of IDR 35,440,000. This farming is feasible with an R/C of 3.08, and becomes a profitable and sustainable farm, as well as a choice of model for using labor-intensive funds.

Texto completoResumen
Viruses, the most abundant microorganisms in the ocean, play important roles in marine ecosystems, mainly by killing their hosts and contributing to nutrient recycling. However, in models simulating ecosystems in real marine environments, the virus-mediated mortality (VMM) rates of their hosts are implicitly represented by constant parameters, thus ignoring the dynamics caused by interactions between viruses and hosts. Here, we construct a model explicitly representing marine viruses and the VMM rates of major hosts, heterotrophic bacteria, and apply it to two sites in the oligotrophic North Pacific and the more productive Arabian Sea. The impacts of the viral processes were assessed by comparing model results with the viral processes enabled and disabled. For reliable assessments, a data assimilation method was used to objectively optimize the model parameters in each run. The model generated spatiotemporally variable VMM rates, generally decreasing in the subsurface but increasing at the surface. Although the dynamics introduced by viruses could be partly stabilized by the ecosystems, they still caused substantial changes to the bacterial abundance, primary production and carbon export, with the changes greater at the more productive site. Our modeling experiments reveal the importance of explicitly simulating dynamic viral processes in marine ecological models.

Texto completoResumen
The prehistoric period of the northern American Southwest is characterized by increased population, increased agricultural production, and regional depopulation. Most current models of evolutionary change that attempt to explain these phenomena are defined at the scale of "culture" or of a specific adaptation, e.g., "Anasazi adaptive system." I suggest that for most purposes these are not productive constructs, and that their application makes useful explanations difficult, if not impossible to formulate. As a further liability, these models ignore the role of natural selection as an explanatory mechanism, preferring instead to seek explanation through the premature application of the concept of adaptation. The application of a selectionist perspective, as opposed to the more popular adaptationist model, leads to the conclusion that the operation of natural selection favoring productive specialization accounts for the characteristics noted above for the prehistoric American Southwest.

The fermentative kinetic properties of different batches from the red yeast mutant strain GL-5 with high productive β-carotene were investigated by using a 5-L fermenter. Based on the Logistic equation and the Ganden classification, the kinetic models for the cell growth, base material consumption and yield of product were obtained. These mathematic models were in good consistent with the experimental values, and could provide theoretic basis for controlling and further pilot fermentative production of β-carotene from this mutant strain GL-5.

The authors showed that large dairy complexes for over 2,000 cows create an increased environmental burden on the environment. The main tasks arising in this case were named: creating an optimal indoor microclimate for different age and gender groups of animals; providing sparing and comfortable modes of technological, veterinary and sanitary care and keeping animals; waste recycling; increasing the productive longevity of cows up to 4-5 lactations. (Research purpose) To develop methodologies for modular construction of an expanded standard-size range of new generation automated and robotic livestock farms. (Materials and methods) The authors proposed the main criteria and indicators for building a "smart" farm: minimum feed costs per unit of production; reduced energy consumption; optimal capital intensity of equipment and engineering structures per one livestock place; the minimum cost per unit of production with its high quality. The authors received the criterion equation for the total functional of the dairy farm. (Results and discussion) The authors analyzed the structural and functional diagrams of various configuration and size dairy farms (T-H-shaped), including combined storage farms, which make it possible to create a combined functional and logistics infrastructure consisting of standard modular units. The authors proposed the concept of building a technological module for a "smart" robotic farm for 400 heads with combined sectional feed and waste storage facilities, a robotic milking parlor, a multifunctional electrified robotic feed loader-pusher-dispenser and equipment for microclimate differentiated provision. (Conclusions) The authors developed methods, models, structural and functional schemes for modular construction of new generation automated and robotic dairy farms of various shapes and sizes. Their following advantages were confirmed: the optimal construction time, a sparing effect on biological objects and the environment, an increase in the production digitalization and automation level, the animal productive longevity, the dairy farming profitability in general.

Estuaries are highly productive habitats that support fisheries production. However, the importance of mangrove carbon to estuarine consumers can differ considerably among systems. In this study, we used stable isotopes (δ13C, δ15N) to investigate the importance of mangrove carbon as an energy source to estuarine consumers in the Atrato River Delta, Colombia, an area where fringing mangroves dominate the coastline and where other productive coastal habitats that may otherwise support the food web are absent. Basal resources and consumers were collected from mangrove and nearshore habitats during the rainy season. Results revealed a food web with a maximum length of 4.6 trophic positions. Bayesian mixing models indicated that most consumers used a mixture of basal sources, which suggests intertwined energetic pathways. However, mixing models also indicated that some species relied more heavily on some basal sources than others and revealed trophic pathways (food chains). Mangrove carbon directly supported herbivorous crabs (Sesarmidae) and indirectly supported planktivorous fish (Engraulidae) and piscivorous fish. Mangrove carbon also contributed significantly to the diet of 2 of the most common fish species in the local artisanal fishery: Centropomus undecimalis (mean: 46%; credibility interval [CI]: 1-80%) and C. pectinatus (mean: 33%; CI: 1-78%). Our findings highlight that mangrove carbon can be an important food source in areas without other productive coastal habitats and can play an important role in sustaining the production of fisheries.
