Alternative methods of insect management are an important field of study for agriculture. The current study aimed to determine the effect of aqueous extracts from Simarouba sp. (AE-S) on the biology of Plutella xylostella and to determine the toxicity of the extract to the nematode Caenorhabditis elegans (an important in vivo alternative assay system for toxicological study). Lyophilized AE-S was chemically investigated by Ultrahigh-performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS). We evaluated the effect of the botanical extract on the life cycle of P. xylostella, from larval stage to adult stage, at concentrations of 10%, 5%, 1%, 0.1%, 0.05%, and 0.01% and a control. Subsequently, we analyzed the toxicity of the extract in an in vivo model. AE-S showed high amount of phenolic and flavonoid compounds. Six compounds were identified based on UHPLC-MS/MS analysis, including flavanone, kaempferol, 4,5-dimethoxycanthin-6-one, 11-acetylamarolide, ailanthinone, and glaucarubinone. The median lethal time for P. xylostella was estimated to be 96 h in all concentrations of AE-S, and at 120 h, 100% of the individuals were dead. Larvae exposed to AE-S at concentrations of 0.01, 0.05, and 0.1% showed a reduction in leaf area consumption, underdevelopment, and reductions in movement and pupal biomass. The lowest concentrations of AE-S (0.1%, 0.05%, and 0.01%) did not cause mortality in nematodes. Thus, the aqueous extract of Simarouba sp. could be an effective control tool because it mainly acts in the larval stage, the stage at which the insect causes damage to brassicaceae.

Authors: Qin Hao , Zou Hua , Ji Huimin
Published: May 2023

The green manufacturing innovation ecosystem provides a critical pathway for the interactive innovation balance between exploratory and exploitative technology innovation for green enterprise manufacturing. Under finite rationality, we construct a three-party evolutionary game model and its dynamic replication equations among the enterprise, scientific research, and support layers. We numerically simulate the decision-making behavior of the three parties with the BYD case study to analyze the influence of each parameter on the evolutionary outcome. The results show that the maturity and innovation degree of green manufacturing exploratory and exploitative innovation technologies can effectively measure the degree of innovation balance of the enterprise. Strengthening the scientific research layer to adopt green manufacturing technology innovation research and development for the enterprise and reducing the “conflict” will promote the enterprise to engage in exploratory innovation, which in turn will encourage the decision of enterprise interactive innovation balance. The support layer actively searches for information and supports the green manufacturing innovation ecosystem with information, funding, and other innovation resources, thus facilitating enterprises to engage in interactive innovation balance.

Authors: Jing Peng , Zha Ye , Pan Kewen , Xue Ying
Published: May 2023

School buses could alleviate the emissions associated with school travel. China is devoted to promoting its school bus service, leaving parents in a dynamic process of change from the original school travel mode to using the school bus service. This study analyzes parents’ switching intentions regarding school buses and decomposes the dimensions of certain critical factors by applying the Push–Pull–Mooring model. We conducted an online questionnaire survey of 463 parents. The measurement model result showed a satisfying prediction power, superior to that of existing theories. The results showed that perceived service quality is the most influential factor in the initial stage of school bus promotion. Among the four dimensions of perceived service quality, parents emphasize reliability and comfort. These results contribute to a deeper comprehension of parents’ intentions to switch to school bus services during the rollout phase and to ensuring sustainable school travel.

Published: May 2023

Sustainable development is present in almost every aspect of today’s life. The European Green Deal is characterized by a holistic approach that covers both energy sectors and other spillovers for European Union countries. Implementing the European Green Deal requires many different activities in three main areas. In the countries of the European Union, policies are being implemented to reduce the negative impact of economic activity on the natural environment, because it also affects human health and may even threaten the vitality of some populations. In this article, the research conducted was aimed at identifying actions taken by businesses in order to implement the guidelines of the European Green Deal and the factors hindering and motivating the implementation of eco-changes. It is a program that should be implemented in countries and visible in the activities of enterprises. However, what is its real impact on the pro-ecological and pro-social activities of enterprises? Answers to the listed questions were obtained on the basis of the opinion of an inter-national group of professionals. The study is international, and is a comparative analysis. Operational activities undertaken by businesses in order to implement the guidelines of the European Green Deal and of environmental protection, as well as factors hindering and motivating the implementation of environmental changes, were identified and then verified in the study.

Authors: He Kun , Qin Dongchen , Chen Jiangyi , Wang Tingting , Wu Hongxia , Wang Peizhuo
Published: May 2023

Driving style has a significant effect on the operating economy of fuel cell buses (FCBs). To reduce hydrogen consumption and prolong the fuel cell life of FCBs, this paper proposes an online adaptive equivalent consumption minimum strategy (A-ECMS) based on driving style recognition. Firstly, driving data from various drivers is collected, and a standard driving cycle is created. Neural networks are then used to identify driving conditions, and three fuzzy logic recognizers are developed to identify driving styles for different driving conditions. The driving style factor is associated with the equivalent factor using an optimization algorithm that incorporates hydrogen consumption cost and fuel cell degradation cost into the objective function. Simulation results demonstrate that the proposed A-ECMS can reduce equivalent hydrogen consumption, prolong fuel cell life, and result in a 6.2% reduction in total operating cost compared to the traditional method.
Life Value Assessment Methods in Emerging Markets: Evidence from China
Authors: Tan Liang , Cao Aochen , Qiu Dongyang , Liang Bolin
Published: May 2023

The paper explores life value assessment methods in China from both the historical and modern perspectives. The historical perspective includes the death penalty ransom approach and government pricing approach, while the modern perspective contains the human capital method and willingness-to-pay method. The human capital method measures the economic value created by people and uses it as their life assessment value, and the willingness-to-pay method evaluates peoples’ life value indirectly through the trade-off between the death risk and benefit. The paper then puts forward improvement ideas for the two modern life value assessment models and proposes possible future research directions, meanwhile providing a reference for such practical issues as compensation policymaking for industrial injuries or deaths for the sustainable development of emerging countries.
Environmental History and Commons for the Colombian Caribbean Challenges
Authors: Herrera Arango Johana
Published: May 2023

Environmental history, as a field of analysis and transdisciplinary study, aims to explore the interactions between society and ecosystems from a deep understanding of how relationships between human groups and natural systems change over defined periods of time. This article seeks to delve into the environmental history of the savannahs of the Cesar department in Colombia, documenting the milestones in the privatization of the commons and the degradation of social–ecological systems. Methodologically, satellite images and aerial photographs are analyzed to determine the changes in land cover that reveal the state of the ecosystems, and an ethnographic approach is used to document the perception and valuation of local Afro-descendant communities in the region. The article shows how, over the last 60 years, land-use planning models have favored individual appropriation practices and agroindustrial models over collective forms of pastoralism and small-scale agrifood systems. It also documents the main socio-ecological impacts and the conflicts implicit in different tenure models that should be taken into account in the various public policies related to sustainability, peace building, and the recognition of territorial rights in the Colombian Caribbean.
Application of Fractional SIQRV Model for SARS-CoV-2 and Stability Analysis
Authors: Öztürk Zafer , Bilgil Halis , Sorgun Sezer
Published: May 2023

Throughout history, infectious diseases have been the cause of outbreaks and the deaths of people. It is crucial for endemic disease management to be able to forecast the number of infections at a given moment and the frequency of new infections so that the appropriate precautions can be taken. The COVID-19 pandemic has highlighted the value of mathematical modeling of pandemics. The susceptible–infected–quarantined–recovered–vaccinated (SIQRV) epidemic model was used in this work. Symmetrical aspects of the proposed dynamic model, disease-free equilibrium, and stability were analyzed. The symmetry of the population size over time allows the model to find stable equilibrium points for any parameter value and initial conditions. The assumption of the strong symmetry of the initial conditions and parameter values plays a key role in the analysis of the fractional SIQRV model. In order to combat the pandemic nature of the disease, control the disease in the population, and increase the possibility of eradicating the disease, effective control measures include quarantine and immunization. Fractional derivatives are used in the Caputo sense. In the model, vaccination and quarantine are two important applications for managing the spread of the pandemic. Although some of the individuals who were vaccinated with the same type and equal dose of vaccine gained strong immunity thanks to the vaccine, the vaccine could not give sufficient immunity to the other part of the population. This is thought to be related the structural characteristics of individuals. Thus, although some of the individuals vaccinated with the same strategy are protected against the virus for a long time, others may become infected soon after vaccination. Appropriate parameters were used in the model to reflect this situation. In order to validate the model, the model was run by taking the COVID-19 data of Türkiye about a year ago, and the official data on the date of this study were successfully obtained. In addition to the stability analysis of the model, numerical solutions were obtained using the fractional Euler method.
Organizational Routines and Digital Transformation: An Analysis of How Organizational Routines Impact Digital Transformation Transition in a Saudi University
Authors: Almatrodi Ibrahim , Skoumpopoulou Dimitra
Published: May 2023

This study was undertaken in response to the current lack of research identifying organizational routine influences that are exerted on organizations, including in relation to digital transition. Digital transformation refers to the integration of digital technologies, such as data analytics and automation, into an organization, engendering changes in its work routines, processes, structure, and culture. However, digital transition is a strategic process involving significant structural and procedural changes in the shift from one technology to another. Therefore, understanding the effect of organizational routines is essential for understanding how digital transformation impacts an organization, and how best to manage this transition. This study explores the impact of organizational routines on digital transition, in order to understand how they can facilitate a successful digital transformation. It employs a single case study of a university that recently implemented digital technologies, including big data analytics and automation, in some of its managerial services for its employees. It marked a significant technological shift for this public university, and the study specifically explores how the organizational routines affected this digital transition, particularly in terms of managerial and administrative issues. In modern times, many universities worldwide have undergone significant changes, and it is therefore essential to document the impact of organizational routines on digital transition, especially in developing countries where universities play a crucial societal role. The complexity of universities as organizations, and the interaction between organizational routines and digital transition highlight the importance of a case study approach for understanding this complexity. The university with which this study is concerned is a leading public university that holds considerable influence and a leadership role within the higher education sector, and which has adopted various technologies and information systems. The success of the digital transformation at this university may have a significant impact on other universities in the region and encourage them to adopt similar approaches to digital transition and digital transformation in the future, if they understand the impact of organizational routines in such transitions. The results show that organizational routines play a leading role in digital transformation transition; moreover, some aspects can explain the ways in which these routines influence digital transformation transition, such as inherited status, the adaptation of technology and changes to current organizational settings, and power. This study can contribute toward the successful implementation of digital transformation and influence the strategies adopted for the transitions required by digital technologies.

Published: May 2023

Seven brands of veterinary rabies vaccines are commercially available in Sri Lanka, but there is no established procedure to test the potency of the vaccines at the local level, especially prior to their release. The aim of this study was to test the potency of these vaccines using a mouse challenge test in collaboration with the EU/WOAH/WHO Reference Laboratory for Rabies, ANSES-Nancy, France. Based on the European Pharmacopoeia, the inactivated rabies vaccines complied with the mouse potency test if the estimated potency is ≥1.0 IU in the smallest prescribed dose. Among the eight tested vaccines, four single-dose preparations (Rabisin™, Raksharab™, Nobivac™ RL, and Nobivac™ Rabies) were compliant, with potencies of 12 IU/dose, 7.2 IU/dose, 4.4 IU/dose, and 3.4 IU/dose, respectively. Three of the single-dose preparations (Canvac™ R, Defensor™ 3, and Rabies killed vaccine) were not compliant, with potency values <1.0 IU/dose. One multidose preparation (Raksharab™ multidose) had a potency of 1.3 IU/dose, even though the test was not validated. Based on these results, it appears that some rabies vaccine batches that are currently available in the local market do not comply with the mouse potency test. Testing the vaccines’ potency before registration and release to the market appears to be an important step to allow good immunization to animals during pre-exposure vaccination programs.

Published: May 2023

(1) Background: As the COVID-19 pandemic enters its fourth year, it continues to cause significant morbidity and mortality worldwide. Although various vaccines have been approved and the use of homologous or heterologous boost doses is widely promoted, the impact of vaccine antigen basis, forms, dosages, and administration routes on the duration and spectrum of vaccine-induced immunity against variants remains incompletely understood. (2) Methods: In this study, we investigated the effects of combining a full-length spike mRNA vaccine with a recombinant S1 protein vaccine, using intradermal/intramuscular, homologous/heterologous, and high/low dosage immunization strategies. (3) Results: Over a period of seven months, vaccination with a mutant recombinant S1 protein vaccine based on the full-length spike mRNA vaccine maintained a broadly stable humoral immunity against the wild-type strain, a partially attenuated but broader-spectrum immunity against variant strains, and a comparable level of cellular immunity across all tested strains. Furthermore, intradermal vaccination enhanced the heterologous boosting of the protein vaccine based on the mRNA vaccine. (4) Conclusions: This study provides valuable insights into optimizing vaccination strategies to address the ongoing challenges posed by emerging SARS-CoV-2 variants.

Published: May 2023

This systematic review and meta-analysis sought to evaluate the acceptability levels for COVID vaccine(s) in various states in India. Published articles in PubMed/Scopus/Cochrane/DOAJ/the Web of Science that focused on assessing COVID-19 vaccine hesitation/vaccine acceptance using a survey/questionnaire were included. After extensive research, 524 records were found, and after screening on the basis of eligibility criteria, only 23 papers were added to this review. Increased vaccine assumption percentage (>70%) among the population was found in two surveys nationwide (92.8%) and in Delhi (79.5%). For pooled estimates of COVID-19 vaccine acceptance and heterogeneity, twenty-three studies (23) consisting of 39,567 individuals reported for acceptance of COVID 19 vaccine in India.. Out of these, 26,028 individuals accepted the COVID-19 vaccine, giving a pooled estimate of 62.6% (95% CI: 55.6–69.4) with considerable heterogeneity (χ2 = 3397.3, p < 0.0001; I2 = 99.40%). The results of this study give a brief insight into the percentage acceptance and hesitancy among the Indian population regarding COVID-19 vaccine immunisation. Future research and vaccine education initiatives can be steered by the findings of this work as a starting point.

Published: May 2023

The purpose of this study was to evaluate the agreement between three methods for measuring pupil size in patients implanted with multifocal intraocular lenses (MIOLs): Keratograph 5M (K5M), Pentacam AXL Wave (PW), and a simple hand ruler. Sixty-nine subjects implanted with MIOLs and measured at the three-month follow-up visit were included in this retrospective analysis. K5M and PW were used to measure the photopic (PP) and mesopic (MP) pupil sizes, and a hand ruler was used to measure the pupil under environmental light conditions (135 lux). The Bland–Altman method with its limits (LoAs) was used to assess the agreement. The median PP was 2.8, 2.95, and 3 mm for K5M, PW, and the ruler, respectively (p < 0.05). Differences in PP were statistically significant for all paired comparisons (p < 0.0005) except between PW and the ruler (p = 0.44). The LoAs for the difference in PP between K5M and PW was 0.63 mm. The mean difference for MP between K5M and PW was 0.04 mm (p = 0.34) with LoAs of 0.72 mm. MP measured with K5M and PW could be considered interchangeable, although a correction of −0.3 mm (IC95%: −0.23 to −0.39) should be applied to PP measured with PW to attain the K5M mean.

Floods are a natural phenomenon that cause damage to structures and property as well as negatively affect human life. Assessing the extent, speed, power, and depth of flooding has always been a challenge for water resource planners. This research developed a hydraulic simulation model for the Cubanicay and Bélico urban rivers embedded in the city of Santa Clara, Cuba. The methodology was based on a one-dimensional model of the Hydrological Engineering River Analysis System (HEC-RAS) and GIS-based methods. The HEC-RAS model (Beta) and three modeling flood tests for scenarios of 1% (100 years), 2% (50 years), and 10% (10 years) of probability for hydrometeorological events were analyzed. Bank lines, flow path lines, and cross-section cut lines were extracted from Digital Elevation Models. Manning’s roughness coefficients were considered for the channel morphology and soil typology. The flood Beta model results were accurate with a difference of ±0.10 m considering the water footprint found in the field. The results showed that the areas near the control section 2 + 87 presented a high risk of flooding. The flood limit map for urban areas could be an important tool for researchers, planners, and local governments for risk assessment and to develop evacuation plans and flood mitigation strategies in order to reduce human and economic losses during a flood.

Foreign biologically active substances that can be contained in milk of cows, which having a negative impact on the health and quality of life of people are antibiotics. Intensive use of antibiotics in veterinary practice contributes to the globalization of micro doses in the environment, accelerates the evolution and spread of resistant forms of microorganisms. The principle of prioritizing the safety of dairy products, based on the mandatory control of raw milk for the content of residual amounts of antibiotics, is implemented in accordance with the requirements of regulatory and technical documents. There is a need to use high-tech laboratory methods of detection of antimicrobial drugs in raw materials and livestock products. The purpose of the research was to control the contamination of raw milk by antibiotics. Raw milk of morning milking from cows of Black-and-White breed was used for the research. Milk was obtained at the zoo station of the Federal State Budgetary Educational Institution of Higher Education “Russian State Agrarian University – Moscow Timiryazev Agricultural Academy”. In the samples residual amounts of antibiotics of diff erent pharmacological groups, most widely used in productive animal husbandry were determined. Sampling of raw milk and their preparation for research was carried out in accordance with State Standard T 26809.1-2014. The determination of residual amounts of antibiotics was carried out by the method of an internal standard for the areas of chromatographic peaks of identifi ed compounds using a calibration characteristic obtained by analyzing calibration solutions of known compounds under similar conditions. It was established that monitoring the health of lactating cows, strict compliance with the rules for the use of veterinary medicines, the exclusion of errors in the technology of production of feed and feed additives, contribute to minimizing contamination of raw milk by antibiotics.

The use of chelated compounds (mineral proteinates) in animal diets has a targeted effect on specific functions and enzyme systems of the body, since they are absorbed intact. The purpose of the work was to study the influence of chelated compounds of trace elements in the composition of the metalloprotein “Belmin” on the blood content of broiler chickens of total protein, its fractions, as well as free amino acids. In order to determine the eff ect of chelated compounds of trace elements in the composition of the metalloprotein “Belmin” on the indicators of protein metabolism in blood serum 9 heads of broiler chickens of 37-day-old age (per 3 heads in each; in the 1st control, 2nd and 3rd experimental groups) were selected. The metalloprotein content in the 2nd experimental group was 0,20 %, in the 3rd experimental group – 0,15 % of the feed weight. It was determined as a result of the studies that the concentration of total protein in the blood serum of chickens of the 1st control and experimental groups was within the normal range, but its higher level was recorded in the 2nd experimental group (47,5 g/l vs 45,6 g/l in the control). The content of blood protein fractions (albumins, α- and β-globulins) responsible for the transport of certain substances in the experimental groups was also higher (52,4 % of albumins in the 2nd experimental group and 42,5 % in the control) the content of protein fractions was calculated as % of the total protein level. Also, in the blood serum of experimental broiler chickens a higher content of free amino acids (both replaceable and nonreplaceable) was observed compared with the control group, which indicates a more intensive protein metabolism in broiler chickens in the 2nd and 3rd experimental groups. The amount of free amino acids in the blood serum of chickens in the 2nd and 3rd experimental groups exceeded the control group by 12,74 and 13,57 mg%, respectively.

One of the trends in meat production is to reduce feed expenditures per unit of live weight gain while simultaneously increasing the growth rate, slaughter yield, muscle yield and reducing the content of internal fat. Reducing the fat content in the carcasses of quails will improve the feed conversion and increase the yield of muscle tissue. One of the ways to reduce the prime-cost of poultry products is the introduction of non-traditional promising feed ingredients. The purpose of the research was to study the use of sorghum grain in feeding quails of meat productivity. The results of the infl uence of complete nutrient-balanced compound feed with the introduction of 10 % sorghum on livestock and economic indicators in the rearing of meat quails have been presented the article. It was found that the live weight of quails in the experimental group increased by 0,46 %, while the average daily feed intake decreased by 4,39 %. Feed expenditures per 1 kg of live weight gain of the experimental group were 5,08 % lower due to better assimilation of feed nutrients. It was found according to the results of physiological (balance) experiment that the digestibility of crude protein increased by 6,92 abs.%, crude fat by 0,73 abs.%, crude fi ber by 0,82 abs.%. It was found when calculating economic indicators that the use of sorghum in compound feed for quails allowed to increase the yield of meat and revenue from its sale by 5,81 %. Despite the increase in the total cost of the feed consumed by the experimental group by 1,43 %, the profi t was received by 58,14 % more. The prime-cost of production of 1 kg of quail meat in the experimental group decreased by 6,20 % compared with the control group.

The purpose of the study is to substantiate the economic efficiency and riskiness of an investment project for laying (restoring) shelterbelts on the example of the municipality Dinskoy district of the Krasnodar Territory, located on the territory of the fifth alluvial-loesslike flat landscape with plowed steppes. An analysis was made using GIS technologies of the current state of the existing field-protective forest belts in the territory under consideration, the areas of their laying and the volume of necessary repair work were determined. A project for laying (restoring) a system of field-protective forest belts has been developed, the amount of necessary capital investments in forest reclamation measures has been determined, and expected indicators of efficiency and riskiness of investments have been calculated. In the course of the study, it was taken into account that without timely work to restore forest belts, the yield of winter wheat, the main agricultural crop in the region, could be reduced by 30–70 % in the long term, which would result in large losses in cash receipts and profits for commodity producers. It has also been proven that for the effective implementation of the proposed project, it is important to provide state subsidies for at least 30 % of the amount of capital investments incurred

In order to accelerate the process of introducing new selection achievements into production, it is necessary to provide agricultural producers with a suffi cient number of original and elite seeds. Therefore, the development of technological methods for accelerating the reproduction of seed material based on the use of chelated micro fertilizers is very relevant. The purpose of the research is to study the variability of quantitative characteristics of pea varieties under the action of chelated micro fertilizers to increase the effi ciency of seed production in the cultivation of original and reproductive seeds. The research material was original seeds from the selection nursery of the fi rst year of three varieties of peas, which were selected by the Federal State Budgetary Institution “Federal Rostov Agrarian Scientifi c Center” such as Aksai usatii 5, Alliance and Ataman. Aksai usatii 5 variety served as a standard. It has been established that in seed production of Aksai usatii 5 and Ataman varieties, it is possible to achieve high yields and increase the reproduction coeffi cient of seeds of higher reproductions, as well as to improve their sowing qualities by using double foliar top dressing of ORMISS containing Cu/B or Cu/Mo. In the seed production of Alliance variety with accelerated reproduction of original seeds to achieve high yields as well as to improve their sowing qualities use ORMISS with boron or molybdenum for seed treatment in combination with the treatment of plants in the 3–5 leaf phase. When choosing pea varieties for introduction into production, along with Aksai usatii 5 variety, preference should be given to Alliance and Ataman varieties, as high-yielding and economically profi table.

En l’espace de neuf mois, de juillet 1991 à avril 1992, la Mauritanie est passée d’un pouvoir militaire passablement autocratique à un ensemble de dispositifs institutionnels inspirés des modèles démocratiques euro-américains. Les conditions de mise en œuvre du processus électoral comme ses résultats montrent qu’il n’a pas essentiellement bouleversé le paysage politique qui lui préexistait. Il a seulement contribué à (r)amener au premier plan, et en quelque sorte à officialiser, l’intervention, dans le champ du pouvoir, des luttes de classement fondées sur l’ethnie et la tribu, qui, en sous-main, en ont toujours constitué un élément déterminant.
Entreprendre au Sénégal après la dévaluation

Business in Senegal after the devaluation.

The devaluation of the CFA franc modifies the entrepreneurs’ financing networks as well as the pressures they come under from their social environment. To make up for the gaps of the banking system and the surge of interest rates, investment committees based on pre-established ties are created. The change in parity reduces the profitability of firms when the community pressures are increasing. The rise in imports encourages manufacturers to equip themselves with second hand technologies. Devaluation can be synonymous with euthanasia for the business world or on the contrary with revitalization.
Zaïre : l’officiel contredit par le réel

In Zaire reality is in contradiction with the state.

Today in Zaire , real life takes place out of the State and its institutions. This grassroot social regulation has made possible the development of new positions of power out of State’ control or substitution of monopoly. These positions of power which correspond to the actual needs of the population are mushrooming in the streets of the country’s main towns. It is the case of the open currency markets and the new communities of prayers.
La guerre dans le «Camp Nord» au Congo-Brazzaville : ethnicité et ethos de la consommation/consumation
Authors: Tonda Joseph
Published: May 2023

Ce n’est pas seulement pour des raisons de mobilisation guerrière qu’une fraction de la classe politique à mis à profit les effets sociaux de la situation de guerre et la dichotomie symbolique du territoire national pour procéder de force à une territorialisation de l’ethnicité. C’est aussi en prévision de futures mobilisations électorales. Cependant, dans un cas comme dans l’autre, la métaphore du camp-Nord reste pertinente, dans la mesure où elle insiste sur les effets coercitifs des univers concentrationnaires, militaires et féodaux sur les univers mentaux en situation de mobilisation. Mais elle est aussi intéressante en ce qu’elle suggère une communauté idéologique d’intérêts qui oblitère les différences de classes.

É incontestável a importância da construção civil para a economia global, com efeitos multiplicadores gera a cada emprego direto, no mínimo quatro indiretos, trazendo efeitos positivos para a balança comercial dos países (ABIKO et al, 2005), por outro lado é uma das indústrias que mais impacta o meio ambiente, sendo responsável por 50% do CO2 lançado na atmosfera e em torno da metade dos resíduos sólidos gerados no mundo. No Brasil com o intuito de melhorar a gestão de resíduos foram criadas legislações específicas através da Resolução CONAMA 307/2002 e da Lei 12.305/2010, trazendo, entre outros, o Programa Integrado de Gestão de Resíduos de Construção e Racionalização dos Processos Produtivos induzindo numa melhoria na qualidade de vida da população, através do controle da poluição e contaminação do ar, da água e do solo provocada pela inadequada remoção, tratamento e destinação final dos resíduos sólidos. O objetivo deste artigo é aplicar um Check-List do Programa de Gestão de Resíduos na Construção Civil, que foi desenvolvido de acordo com a legislação e normas vigentes pela Ambitec-Grupo de Pesquisa de Engenharia Aplicada ao Meio Ambiente da Universidade de Pernambuco. Para tal, foi escolhido um empreendimento em andamento na cidade de Recife na qual foi monitorado e avaliado.

O início da exploração do pré-sal é um dos marcos mais importantes da história geológica e econômica do Brasil. Com a enorme disparidade positiva entre a produção prevista antes e após a exploração do pré-sal, há cada vez mais mobilização por parte de empresas e pesquisadores por estudos caracterizando as rochas-reservatório dessa camada. O presente trabalho tem como finalidade a caracterização petrográfica de amostras de rochas carbonáticas de um reservatório do pré-sal brasileiro na Bacia de Santos, que visa analisar a gênese de seus principais componentes sedimentares e diagenéticos através de descrições macro e microscópicas, além da análise de dados petrofísicos correlacionando valores de porosidade e permeabilidade. O objetivo é definir o potencial de reservatório dessas rochas e correlacioná-las com as principais fácies definidas para o intervalo do pré-sal: (i) Esferulitos; (ii) Shrub-Like Limestone; (iii) Grainstone Intraclástico; (iv) Packstone Intraclástico; (v) Dolostone; e (vi) Mudstone/Siltstone. Acerca de todas as amostras analisadas, esferulitos, shrubs e matriz (argilosa, sílica e/ou carbonática) são elementos comuns, tanto in situ, quanto retrabalhados ou substituídos parcialmente. A cimentação das rochas é de dois tipos: sílica, com chert bordejando os grãos, calcedônia e cristais de quartzo, nessa ordem na direção grão-poro; e carbonática, com a cristalização de calcita e dolomita romboédrica por substituição, pelo processo diagenético de dolomitização. Com a análise estatística aplicada nas lâminas delgadas, foi medido o diâmetro de esferulitos e o comprimento de estruturas shrub preservadas, além de espessuras de fraturamentos. Os esferulitos apresentaram média de diâmetro de 1,60 ± 0,76 mm, com o menor e maior grão com 0,25 e 6,92 mm, respectivamente. O comprimento dos grãos com estruturas shrub apresentaram uma média de 3,05 ± 1,44 mm, com menor e maior estrutura com 0,71 e 12,9 mm, respectivamente. Por fim, as fraturas apresentaram espessura média de 0,16 ± 0,07 mm, com menor e maior intervalo de espessura equivalente a 0,01 a 1,47 mm, respectivamente. As medições permoporosas indicaram porosidade com média de 13,77 ± 5,78 % e permeabilidade com média de 172,63 ± 474,90 mD. De forma geral, os valores de porosidade estão entre 10 e 15% e os valores de permeabilidade são muito dispersos e pouco correlacionados com os respectivos valores de porosidade, sugerindo um sistema poroso complexo e heterogêneo.

Os documentos técnicos, chamados de Diretrizes, Consensos ou Posicionamentos são um norte para prática clínica de profissionais da área da saúde. A diretriz clínica está constituída por afirmações sistematicamente desenvolvidas para auxiliar profissionais de saúde e pacientes na tomada de decisão sobre a forma mais adequada de cuidado com a saúde em condições específicas, incluindo a Nutrição. O objetivo da pesquisa foi mapear os documentos técnicos das especialidades e áreas de atuação médica que descrevem sobre o tratamento não medicamentoso que envolve a nutrição como dietoterapia, intervenções nutricionais de interesse para a prática clínica do nutricionista. A pesquisa destes documentos foi realizada nos sites do Conselho Federal de Medicina e nas respectivas sociedades de especialidades e áreas de atuação médicas, segundo a lista da Resolução CFM nº 2.221/2018. Após localizar o documento (diretriz, consenso ou posicionamento) por especialidade ou área de atuação, foi realizada uma busca minuciosa de termos relacionados à nutrição que foram previamente definidos, tais como: nutrientes, desnutrição, enteral, parenteral, alimento, alimentação, peso, dieta, IMC, refeição, obesidade, padrão de dieta, recomendações nutricionais de macronutrientes e micronutrientes, compostos bioativos e suplementos. Do total de 114 sites de entidades representativas das especialidades (n= 55) e áreas de atuação médica (n= 59), foram encontrados apenas 41 documentos técnicos (36%) que se relacionam diretamente à nutrição. Destes 41 documentos selecionados, 28 são diretrizes (68,29%), 09 consensos (21,95%) e 04 posicionamentos (9,75%).  Assim, percebe-se que menos da metade (41 | 36%) dos sites mapeados abordam a nutrição e não são totalmente completos em recomendações nutricionais, abordagem terapêutica dietoterápica, o que demonstra ser insuficiente para uma prática clínica mais assertiva e com embasamento científico. Por meio deste mapeamento das diretrizes, consensos e posicionamentos disponíveis, conclui-se que, embora o estado nutricional, a alimentação adequada e o tratamento não medicamentoso por meio da nutrição exerce papel fundamental para a saúde da população, as recomendações ainda não são suficientemente profundas para o direcionamento da prática clínica do nutricionista, sendo esta pesquisa de suma importância para que os profissionais da área de Nutrição questionem a necessidade de elaboração de documentos técnicos específicos para a Nutrição, podendo ser amplamente consultados para embasamento da prática clínica.

Com as mudanças verificadas nos hábitos e comportamentos da sociedade nos últimos anos, nota-se também uma preocupação com a origem e procedimento para a obtenção do alimento ingerido. Diante desse conceito, surge a carne in vitro, que, por meio de processos tecnológicos é um alimento que pode ser produzido em laboratório, sem que ocorra o abate animal. Então, o objetivo desse trabalho foi o de, por meio de uma revisão bibliográfica, apresentar o conceito e a composição da carne in vitro, os objetivos e as vantagens da sua produção, bem como a aceitação do produto pelo mercado consumidor.
