La Responsabilidad Social Universitaria busca desarrollar estrategias que permitan gestionar de manera adecuada y sostenible los impactos educativos, cognitivos, sociales y organizacionales que se derivan de sus funciones sustantivas. Esta investigación tuvo como objetivo establecer la brecha que existe entre los sistemas de gestión de la calidad y gestión ambiental de la Universidad Francisco de Paula Santander Ocaña, con respecto al cumplimiento del impacto organizacional enmarcado en el eje campus responsable planeado por François Vallaeys. Se empleó una investigación de tipo transversal descriptivo con enfoque cuantitativo, empleando el software estadístico SPSS para el análisis de los datos obtenidos en el cuestionario tipo Likert aplicado a los líderes de los diferentes procesos con el fin de conocer cómo se encuentra la Universidad frente a su actuar como campus responsable. Entre los resultados obtenidos se encontró que a nivel documental los sistemas de calidad permiten dar cumplimiento a los lineamientos propuestos por la responsabilidad social universitaria, sin embargo, las respuestas del instrumento utilizado sugieren que falta ampliar el ámbito de aplicación y hacer divulgación de estas prácticas; por lo cual se proponen estrategias que permitan aumentar y completar las prácticas de responsabilidad social.

Published: August 2021

In the era of healthcare digitalization, automation of some medical processes becomes extremely crucial, especially in situations where it is not possible to receive support quickly enough, for example, due to long wait for a specialist (queues) or absence of the needed specialist. This approach will help to use healthcare resources effectively. Automated audiometry is an example of automated diagnostic procedure based on algorithms and technical means for recording acoustic threshold in order to determine the hearing conditions. This review describes the process of automated hearing testing technology development in detail and several other system components (software, equipment, acoustic stimulation sources). The authors describe their own experience of using the automatic audiometry system. The results of comparative study of automated and clinical tests are presented.

ABSTRACT Guava decline is a complex disease resulting from the parasitism by Meloidogyne enterolobii (Me), which predisposes the plant to root rot caused by Fusarium sp. Three in vitro experiments were carried out with the aim of: (i) selecting the Fluensulfone dosage capable of causing Me mortality; (ii) verifying the effect of Fluensulfone on Pochonia chlamydosporia and Trichoderma harzianum; (iii) evaluating the effect of Pochonia chlamydosporia and Trichoderma harzianum in pure doses and in association with Fluensulfone on Me mortality. Fluensulfone at 2 L.ha-1 had no effect on fungi. The associated and pure doses of treatments had a significant effect on Me mortality. A field experiment was also carried out in a guava orchard where decline occurred. The following treatments were tested: Fluensulfone; P. chlamydosporia; P. chlamydosporia + Fluensulfone; T. harzianum; T. harzianum + Fluensulfone; Carbofuran, and control. All treatments reduced Me population, since relative efficiency was higher than 80%. Fluensulfone used alone or in combination with biological nematicides provided an increase in guava productivity. Maintaining Me population low in the field is an important option for increasing productivity and reducing the losses suffered by farmers.

Published: August 2021

RESUMO Dentre as doenças fúngicas, a mancha marrom de Alternaria (MMA) é a doença mais importante para tangor “Murcott”, causando desfolha, mancha e queda de frutos e, com isso, acarretando muitos prejuízos. Nesse trabalho foi avaliada a eficiência de trifloxistrobina e tebuconazol, em formulação comercial, combinados com pirimetanil, em duas dosagens, e combinado com cobre solúvel em água, comparado com oxicloreto de cobre, no controle da MMA em pomar de tangor ‘Murcott’, com 15 anos de plantio, em Estiva Gerbi/SP. Os tratamentos foram constituídos pela mistura de tanque de trifloxistrobina e tebuconazole a 0,80 L ha-1 com os seguintes fungicidas (L ou kg de produto comercial 2000 L-1): T1- pirimetanil (1,0); T2- pirimetanil (1,5); T3- sulfato de cobre solúvel (1,0); T4- oxicloreto de cobre (3,60). Foi adotado o delineamento de Split-block, em subparcelas, com três repetições de dez plantas na linha entre as duas linhas adjacentes. Os fungicidas foram aplicados mediante turbopulverizador FM Copling, sendo empregada uma vazão de 100 mL (m3) -1. No total foram realizadas 17 aplicações de fungicidas, em intervalos que variaram de 12 a 15 dias. As avaliações consistiram na determinação dos níveis de severidade dos sintomas nos frutos, determinados em três épocas (S1, S2 e S3) a determinação do número de cicatrizes nos frutos, quando realizada a colheita. Verificou-se que os tratamentos constituídos pelas combinações de trifloxistrobina e tebuconazole e pirimetanil, em duas dosagens, foram eficientes no controle do patógeno, assemelhando-se aos resultados do tratamento padrão, representados pela combinação de trifloxistrobina e tebuconazole com oxicloreto de cobre.
Drying effect on the microstructure of compacted salted silt
Authors: Ying Zi , Cui Yu-Jun , Benahmed Nadia , Duc Myriam
Published: August 2021

In this study, the drying-induced microstructure evolution of compacted silt with different salinities is investigated using mercury intrusion porosimetry and environmental scanning electron microscope. The pore size distribution (PSD) of specimens compacted near optimum (w = 17%) exhibited bimodal characteristics. Upon drying (w = 8%), the PSD changed to a trimodal pattern with the appearance of a new nano-pore population. This suggested the development of nano-fissures, which could occur in the clay fraction and at the interface between clay particles and silt/sand grains due to the clay shrinkage. With further drying (w = 3%), the nano-pores disappeared and the PSD recovered to bimodal characteristics, suggesting that the nano-fissures created were enlarged until they became micro-fissures. The salinity seemed to decrease the frequency of the drying-induced micro-pores due to the enhanced mechanical strength of salted soil by the soil aggregation resulting from the compression of the diffuse double layer and a possible cementation effect produced by precipitated salt. However, the salinity effect was relatively low, owing to: (a) the low clay fraction (15·7%) and the low-activity clay minerals (illite, chlorite and kaolinite); (b) the low specific surface area (24 m2/g), which limited the salinity effect on the diffuse double layer.
Briefing: Calling for a norm-critical perspective of digitalisation
Authors: Carlsson Linnéa
Published: August 2021

A question that becomes important as the level of digitalisation increases in society and businesses is accounting for how one interprets digitalisation. There are positive examples of digitalisation in relation to gender, age and physical ability and how digital technologies can positively enhance a workplace, although the norm-critical perspective is seldom represented. A more dynamic perspective such as the norm-critical is needed to depict potential limiting structures or assumptions interpreted by digitalisation. This briefing paper takes on an interpretative approach using the Swedish manufacturing industry as a case to illustrate the perspectives related to gender, age and physical ability relative to digitalisation. The norm-critical perspective has formed the narrative and viewpoints presented in this paper. The aim is to highlight the norm-critical perspective as a potential analytical lens among researchers and industry professionals alike to understand how digitalisation is negotiated and given value and how digitalisation is manifested and interpreted to that given value.
A legally-binding instrument on business and human rights: Implications for the right to development in Africa
Authors: Atabongawung Tamo
Published: August 2021

SUMMARY This article examines the relationship between business actors and the implementation of the right to development in Africa. It focuses on the implications of a possible (future) international legally-binding instrument on business and human rights. Although there is no guarantee that such an instrument will eventually be adopted and ratified by states in the near future, the article nevertheless critically examines ways in which the clarification of some issues associated with this process could help revitalise the implementation of the right to development in Africa. It concludes that a legally-binding instrument on business and human rights might elucidate certain contested human rights principles such as international cooperation and assistance; extraterritoriality and accountability, which are central to a meaningful implementation of the right to development on the continent. Key words: Africa; transnational corporations and human rights; right to development and accountability; African Charter
Tension between the individual's fundamental human rights and the protection of the public from infectious and formidable epidemic diseases
Authors: Makwaiba Basutu S
Published: August 2021

SUMMARY Emerging infectious and formidable epidemic diseases are a cause for concern and a serious threat to the global health. At the time of writing a number of these diseases have no cure. States in their domestic legislation applicable to matters of public health have come up with approaches to deal with such diseases. Zimbabwe has enacted primary legislation and regulations dealing with public health in an effort to suppress and prevent these diseases. The Zimbabwean Public Health Act, for example, authorises the notification of infectious and formidable epidemic diseases and the inspection of infected premises. The Act further empowers the Minister of Health and Child Care to enact regulations. Through the Public Health Regulations, the government of Zimbabwe declared COVID-19 a formidable epidemic disease. Warranted by the Health Act, the Minister of Health and Child Care made treatment, testing, detention and isolation compulsory during the period in which COVID-19 is declared a formidable epidemic disease. This article seeks to provide a critical analysis of these measures as provided in the Public Health Act and health regulations in light of the constitutionally-guaranteed rights of privacy, freedom of security, liberty and freedom of movement. The question sought to be answered by the author is whether these measures justifiably trumps the rights of individuals. Key words: infectious diseases; formidable epidemic diseases; public health; fundamental human rights; legislation
The protection of individual labour rights in Zimbabwe
Authors: Kasuso Tapiwa G , Madebwe Tinashe
Published: August 2021

SUMMARY The protection of individual labour rights in Zimbabwe is deficient despite the fact that the Constitution protects these rights. In looking to explore how this could be addressed, this article considers the evolution of the state's obligation to protect individual labour rights to this point and relies on individual labour rights protection at a global level with particular insights drawn from the approach taken to the protection of these rights in two jurisdictions, namely, England and South Africa. The approach to the protection of individual labour rights in these two jursidictions has influenced the Zimbabwean approach to highlight that effective protection of individual labour rights is possible only when courts actively look to protect these rights. The article argues that the reason for deficiencies in the Zimbabwean approach is the fact that courts are not doing enough to protect individual labour rights in Zimbabwe. The solution to this issue, therefore, lies in Zimbabwean courts taking a more proactive role in protecting individual labour rights. Key words: labour rights; constitutionalism; individual labour rights; codification; acccess to court
Realising the right of access to water for people living on farms: The impact of the KwaZulu-Natal High Court decision in Mshengu v uMsunduzi Local Municipality
Authors: Chamberlain Lisa , Khunou Kelebogile
Published: August 2021

SUMMARY Access to water is a constitutionally-protected right in South Africa and an energetic flow of laws, policies and programmes have been initiated to address historical inequalities in the supply of water since the dawn of democracy. Yet despite this, millions of people living in South Africa still have inadequate access to water. Access to water is a particular challenge for people living on farms. By providing an analysis of the case of Mshengu & Others v uMsunduzi Local Municipality & Others, decided by the High Court of South Africa, KwaZulu-Natal Division, Pietermaritzburg, this article seeks to make two key contributions. First, it highlights the challenges experienced by farm dwellers in realising their right to water and locates these challenges within a legal framework which places obligations on both municipalities and private land owners to provide access to water on farms. In particular, the mechanism of water services intermediaries envisaged in the Water Services Act 108 of 1997 is explored as a way to delineate and facilitate the role of private land owners in realising the right to water for farm dwellers. Second, drawing on debates around how the value of public interest litigation can be understood, the article interrogates the value of the litigation in the Mshengu case. Key words: right to water; water services intermediaries; farm workers; labour tenants; public interest litigation

American memory war of the protest movement «Black live matter»
Authors: Martynov Andriy
Published: August 2021

Americans as a nation are more focused on the present and the future than on the past. Until recently, various «historical traumas» have not been the subject of current American political discourse. The American dream focuses on the needs of everyday life, not on the permanent experience of the past.

The aim of the article is to highlight the peculiarities of symbolic conflicts over the sites of the Civil War in the United States in the context of the 2020 election campaign.

Research methods are based on a combination of the principles of historicism and special historical methods, in particular, descriptive, comparative, method of actualization of historical memory.

The scientific novelty of the obtained results is determined by the historical and political analysis of the “wars of memory” during the presidential election campaign in the United States in 2020. Radical political confrontation exacerbates the conflicts of collective memory. This process is not prevented by the postmodern state of collective consciousness, the virtualization of political processes, attempts to form a «theater society». The coronavirus pandemic has raised the issue of choosing a strategy for the development of the globalization process as harshly as possible. Current events break the link between the past and the present, which makes the future unpredictable. Developed liberal democracy is considered the «end of history». Multiculturalism has created different interpretations of US history.

Conclusions. Trump’s victory deepened the rift between different visions of the history of the Civil War. The Democratic majority unites African Americans, Latinos, women with higher education, and left liberals. Attacks on the memorials of the heroes of the former Confederacy became symbols of the war of memory. The dominant trend is an increase in the democratic and electoral numbers of non-white Americans. The «classic» United States, dominated in all walks of life by white Americans with Anglo-Saxon Protestant identities and relevant historical ideas, is becoming history. The situation is becoming a political reality when white Americans become a minority. It is unlikely that such a «new minority» will abandon its own interpretation of any stage of US history, including the most acute. This means that wars of memory will become an organic element of political processes.
HOW CAN THE HUMAN RIGHTS LEGAL FRAMEWORK ADDRESS THE VIOLATION OF HUMAN RIGHTS EXTRATERRITORIALLY?
Authors: Lazarenko M. , Chernohorenko I.
Published: August 2021

The armed conflict in Ukraine has been ongoing since 2014. As to date, the total number of recorded deaths has exceeded ten thousands civilians and combatants. Every day, i.e. during the present research, this number has been increasing. As outlined above, the European regional system of human rights protection, epitomised by the ECtHR, addresses this challenge within two interrelated tracks: individual and inter-State applications. The research focuses on landmark decisions of international, regional, and domestic courts in terms of human rights extraterritorially by way of establishing human rights duty-bearer jurisdiction outside states’ boundaries based on effective control test. It scrutinizes the jurisprudence of the ECtHR in terms of inconsistency between Bankovic and Aj-Jedda cases. In turn, the paper aims to model extraterritorial application of human rights law in Ukraine v. Russia inter-State applications (re Crimea and re Eastern Ukraine) based on Loizidou precedent as well as describes new forms of Russia’s violations of human rights in Crimea.
A Ground-Motion Prediction Equation for the Western and the Southwestern Parts of China Based on Local Strong-Motion Records and an Overseas Reference Model for the Vertical Component
Authors: Xing Hao , Zhao John X.
Published: August 2021

A ground-motion prediction equation for the vertical ground motions from the western and the southwestern parts of China (referred to as SWC) is presented in this study. Based on the Xing and Zhao (2021) study, the Zhao et al. (2017) model (referred to as ZHAO2017) for the shallow crustal earthquakes in Japan was used as the reference model. We used a bilinear magnitude-scaling function hinged at a moment magnitude (Mw) of 7.1. The magnitude-scaling rate for events with Mw>7.1 was determined by records from the SWC dataset and the large events in the Pacific Earthquake Engineering Research Center Next Generation Attenuation-West2 dataset. Site classes (SCs) were used as the site response proxy. All other parameters were derived from the SWC dataset only. The magnitude-scaling rates for events with Mw≤7.1 in this study are larger than in the ZHAO2017 model at most periods. The absolute values of the geometric attenuation rates are larger, and the absolute values of the anelastic attenuation rates are smaller than in the ZHAO2017 model. The between-event standard deviations are smaller than in the ZHAO2017 model at short periods, and the within-event standard deviations are larger than in the ZHAO2017 model at all periods. The differences in the between-site standard deviations vary significantly from one SC to another. We also find that the between-event and within-event residuals are almost independent of magnitude and source distance. The response spectrum attenuates less rapidly than in the ZHAO2017 model at distances less than 30 km.
A 3D Optimized Frequency–Wavenumber (FK), Time–Space Optimized Symplectic (TSOS) Hybrid Method for Teleseismic Wave Modeling
Authors: Meng Weijuan , Yang Dinghui , Dong Xingpeng , Ma Jian
Published: August 2021

Although teleseismic waveform tomography can provide high-resolution images of the deep mantle, it is still unrealistic to numerically simulate the whole domain of seismic wave propagation due to the huge amount of computation. In this article, we develop a new three-dimensional hybrid method to address this issue, which couples the modified frequency–wavenumber (FK) method with the 3D time–space optimized symplectic (TSOS) method. First, the FK method, which is used to calculate the semianalytical incident wavefields in the layered reference model, is modified to compute the wavefields efficiently with a significantly low-memory requirement. Second, 3D TSOS method is developed to model the seismic wave propagating in the local 3D heterogeneous domain. The low memory requirement of the modified FK method and the high accuracy of the TSOS method make it feasible to obtain highly accurate synthetic seismograms efficiently. A crust–upper mantle model for P-, SV-, and SH-wave incidences is calculated to benchmark the accuracy and efficiency of the 3D optimized FK-TSOS method. Numerical experiments for 3D models with heterogeneities, undulated discontinuous interfaces, and realistic model in eastern Tibet, illustrate the capability of hybrid method to accurately capture the scattered waves caused by heterogeneities in 3D medium. The 3D optimized FK-TSOS method developed shows low-memory requirement, high accuracy, and high efficiency, which makes it be a promising forward method to further apply to high-resolution mantle structure images beneath seismic array.

Published: August 2021

The innovative development of the primary sector requires accumulation of human capital and technological knowledge. The dynamics of changes and transformations of the innovative potential of the agrarian sector of Ukraine have been analyzed and their status has been estimated. It has been established that Ukraine lacks the strategic vision of the innovative development within agrarian sector of economy, which results in a partial distortion of the essence of scientific, scientific-technical, innovative, and entrepreneurial activities. It has been defined that effective forming and implementation of the innovative potential necessitate the development of mechanisms that would provide regulatory-legal and institutional support to the effective transfer of innovations, proper funding of science and education, material stimulation in the work of scientific and pedagogical staff, renewal of material and technical base necessary for the introduction of scientific-based innovative activity.
Comparison of Abundance of Premolar and Molar Pulp Stones Before and After Orthodontic Treatment Using Panoramic Radiography
Authors: Afsari Erfaneh , Niksolat Elmira , Ostovar Farzaneh , Karimi Shaghayegh
Published: August 2021

Objectives: Pulp stone is a focal calcification in dental pulp, which is often detected on conventional dental radiographs. Pulp stones can complicate easy access to the root canal and pulp chamber in root canal treatment. Orthodontic treatment may be associated with the formation of pulp stones. Therefore, this study examined the number of pulp stones pre- and post-orthodontic treatment.
Materials and Methods: In this retrospective cross-sectional comparative study, 222 digital panoramic radiographs collected from private orthodontic offices in Rasht, were divided into two groups: radiographs of patients undergoing orthodontic and non-orthodontic treatment according to the inclusion criteria. The obtained data were analyzed by SPSS via the Wilcoxon and Mann-Whitney tests (P<0.05).
Results: The difference in the number of pulp stones pre- and post-orthodontic treatment was significant (P<0.0001). The maximum number of pulp stones after orthodontic treatment was observed in second molars (P=0.016). The change in the number of pulp stones in the mandible (P=0.001) was significantly higher than that in the maxilla (P=0.002). This change was also greater in the left side (P<0.0001) than in the right side (P=0.002). The changes in the number of pulp stones was significant in females (P=0.02). Age had an insignificant effect on pulp stone formation (P>0.05).
Conclusion: This study showed the effect of orthodontic treatment on the number of pulp stones. Further studies are required to clarify the underlying mechanisms for this increase and come up with strategies to prevent it.

Authors: Nadafpour Nima , Montazeri Mostafa , Moradi Mehrdad , Ahmadzadeh Sina , Etemadi Ardavan
Published: August 2021

Objectives: This study aimed to compare the colonization of Enterococcus faecalis (E. faecalis), Escherichia coli (E. coli), Streptococcus mutans (S. mutans) and Staphylococcus aureus (S. aureus) isolated from the oral cavity on different suture materials used in oral implantology.
Materials and Methods: Patients scheduled for implant surgery were included in this study. After flap approximation, the surgical site was sutured using silk, nylon, polyglactin 910 (Vicryl®) and triclosan-coated polyglactin 910 (Vicryl® Plus) sutures in a randomized order. Seven days after surgery, the sutures were removed and incubated in bile esculin agar (for E. faecalis), MacConkey agar (for E. coli), mitis salivarius agar (for S. mutans), and mannitol salt agar (for S. aureus) at 37°C for 24 h. The colonies were then counted. Data were analyzed using the Kruskal-Wallis and Mann-Whitney U tests.
Results: Vicryl® sutures showed the highest accumulation of E. faecalis, followed by Vicryl® Plus, nylon, and silk. There was no significant difference between nylon and silk (P=0.5) or between Vicryl® and Vicryl® Plus (P=0.4). Vicryl® Plus sutures showed the highest accumulation of E. coli followed by Vicryl®, silk and nylon (P<0.01). Vicryl® sutures showed the highest accumulation of S. mutans, followed by Vicryl® Plus, silk, and nylon. Vicryl® Plus sutures showed the highest accumulation of S. aureus, followed by Vicryl®, nylon, and silk.
Conclusion: Nylon sutures showed the least microbial accumulation. Vicryl® and triclosan-coated Vicryl® Plus sutures had no advantage over the commonly used silk sutures in decreasing the number of bacteria.
The role and importance of food industry and food systems during the COVID-19 and the possibility of cold plasma technology for inactivation: a review
Authors: Jahangiri Siahmazgi Mahsa , Ramezan Yousef
Published: August 2021

This article reviews the role and importance of food systems during the COVID-19 outbreak, the impact of this pandemic on the food industry and chain, and examining the methods and possibilities of using cold plasma technology to deal with this pandemic. Since food plays an essential role in human health as an integral part of human life, food safety is critical in such cases. It is essential to adopt practical strategies in controlling the COVID-19 crisis. In the current situation, several methods are used to disinfect and control the spread of disease, some of which are ineffective and can also have problems and limitations. Therefore, emerging technologies such as cold plasma (CP) technology can help facilitate the control process and reduce pandemics. The capabilities of this method are disinfection of food, equipment, production surfaces, and indoor with poorly ventilated spaces of SARS‐CoV‐2 through aerosol microdroplets, which can remain in the air for a long time; such as public transportation, production lines, and restaurants where the possibility of transmitting the SARS‐CoV‐2 is high. On the one hand, this review summarizes all available data related to cold plasma technology as an emerging technology to inactivate SARS‐CoV‐2. It then gives us a brief explanation of the role and importance of the food industry and food supply chain during the pandemic.
Nutrient Uptake and Agronomic Efficiencies of Leaf Litter Compost as Nitrogen Source in Vegetable Cowpea (Vigna unguiculata subsp. unguiculata)
Authors: Das Reshma , Isaac Sheeba Rebecca
Published: August 2021

Nutritional security overrides food security and the present day agriculture focusses more on sustainable and regenerative agriculture in which use of organic inputs assumes prime significance. The search for viable alternatives to the chemical sources of nutrients demands production of the organic nutrient inputs in large quantities. Organic nutrition is expensive on account of the low nutrient contents and large quantum needed and hence unless produced in situ, turn out to be highly expensive. Organic wastes in the form of crop residues are available in plenty in agricultural fields. Tree leaf litter is another biowaste considered as menace under off farm situations. Rapid resource recycling techniques offer immense potential for the safe disposal of the litter and conversion to quality manures. In this background an experiment was conducted to assess the efficacy of litter composts as nitrogen sources in vegetable cow pea (Vigna unguiculata subsp. unguiculata) in terms of the agronomic efficiencies and nutrient uptake. The field experiment was conducted in College of Agriculture, Vellayani, Thiruvananthapuram, Kerala Agricultural University during December 2018 to March 2019 in randomized block design with three replications. The treatments included the compost of the two tree species litter prepared by composting with different decomposer organisms and additives and enriched with the biofertilizer, PGPR Mix I. The results of the experiment revealed the highest vegetable yields (7.80 t ha-1) in the treatment involving mango leaf litter composted with glyricidia leaves and earthworms on par with Kerala Agricultural University package of practices recommendation for cowpea and it was 2.7 times that in absolute control. The total nutrient uptake was the highest with mango litter co-composted with poultry manure as nutrient input. Agronomy efficiency indices, in terms of nitrogen were significantly superior for the treatments including mango litter composts and hence prove a suitable nutrient input in vegetable cowpea cultivation.

Background: Legumes and cereals microgreens are consumed both in healthy nutrition and as a natural food against many degenerative diseases due to their rich bioactive content. The research was carried out to determine the biochemical contents of 5 legumes and 7 cereals. Methods: The research was conducted in Van Yuzuncu Yıl University Field Crops Department Laboratory in 2020, in a controlled growing environment, according to the completely randomized experimental design. Total antioxidant activity, total phenolic, total flavonoid and total ascorbic acid contents and total Chlorophyll, Chlorophyll a, Chlorophyll b and Carotenoid contents and correlation between them were determined. Result: The differences between the means of all traits were found to be significant. The biochemical contents of cereals were 1.6-7 times higher than legumes. There was no big difference between the pigment values. In legumes, Bilensoy alfalfa had the highest total antioxidat activity and total flavonoid content, Uzbek lentil total phenolic content and Goynuk bean had the highest Total ascorbic acid. In cereals, Kirklar oat had the highest total antioxidat activity, total phenolic, total flavonoid and total ascorbic acid contents, while Larende barley had the lowest values (except total ascorbic acid content). While total Chlorophyll and Chlorophyll a amounts were highest in Kirklar barley and lowest in Uzbek lentils, the opposite situation occurred in Chlorophyll b and Carotenoid amounts. There was no significant correlation between biochemical parameters in legumes. There was a positive and significant correlation between total phenolic content with total antioxidant activity and between total ascorbic acid with total fenolic content in cereals. There were positive and significant correlations between all pigment parameters in both legumes and cereals.

Ülkemiz, iklim koşulları açısından papatya bitkisinin doğal olarak yetiştirilmesi için elverişli bir coğrafik konuma sahiptir. Papatya, gerek tıbbi olarak gerek aromatik olarak güncel tedavilerde yoğun olarak kullanılan ve modern tıp tarafından da yoğun olarak ilgi gösterilen bir bitkidir. Halk tıbbında da geniş ve kadim bir kullanımı ve karşılığı olan bu bitki, ülkemizde geniş bir alanda yayılım göstermektedir. Bu çalışmamızda tıbbi papatya olarak kullanılan Matricaria chamomilla (L.) bitkisi, 6 farklı bölgeden (Merkez, Siverek, Bozova, Birecik, Halfeti ve Viranşehir) toplanmış ve klorofil, malondiaaldehit (MDA), prolin, antisiyonin miktarları ile enzim (katalaz, glutatyon redüktaz, askorbat peroksidaz ve süperoksit dismutaz) analizleri yapılmıştır. Analizler toplu olarak değerlendirildiğinde Birecik yöresi örneklerinde katalaz, glutatyon redüktaz ve askorbat peroksidaz enzim aktivite miktarı ile klorofil, prolin ve antosiyaninin en yüksek; süperoksit dismutaz aktivitesinin en az olduğu tespit edilmiştir.

Toplu taşıma araçlarının etkin şekilde kullanılması, akıllı şehir konseptine katkı sağlayacak bileşenlerden biridir. Bu bakımdan, toplu taşıma araçlarının kullanımını kolaylaştıran uygulamaların geliştirilmesi önem kazanmaktadır. Bu çalışmada, bu alanda yapılacak uygulamalara destek olabilecek bir bulanık optimal güzergah öneri modeli ve çözüm algoritması geliştirilmiştir. Bu modelin diğer çalışmalardan esas farkı otobüs içi yoğunluk oranını da dikkate alan bulanık güzergah tercih derecesinin tanımlanmasıdır. Günümüz pandemi sürecinde otobüs içi yoğunluğu dikkate alabilen modelin önemi daha da artmaktadır. Oluşturulan modelde, klasik modellerin aksine, her güzergah, bulanık tercih derecesi eşliğinde önerilmektedir. Çözüm algoritması, bulanık ceza değerleri kullanan Dijkstra benzeri bir algoritmadır. İzmir toplu taşıma ağı verileri kullanılarak yapılan simülatif deneyler yapılmıştır. Önerilen bulanık modele uygun olarak hesaplanan optimal çözümlerin, bulanıklık konsepti kullanmayan klasik yaklaşımdan tercih dereceleri daha yüksek olan çözümler ürettiği görülmüştür.

Sakarya Meydan Muharebesi, hem Türk Devletinin tarihi hem de Dünyanın en uzun süreli ve en büyük meydan savaşı olması yönünden oldukça önem taşımaktadır. Bu savaşta Sakarya Nehri doğusunda 1921 yılında Türk Kuvvetleri ile Yunan Kuvvetleri savaşmışlar ve her iki taraftan da çok fazla insan hayatını kaybetmiştir. Doğa Koruma ve Milli Parklar Genel Müdürlüğü’nün 2015 yılında başlattığı kapsamlı çalışmalarla Şehit Defin Alanları ile Siper hatlarının konumları belirlenmektedir. Dönemin şartları göz önüne alındığında ve Bölgesel Jeomorfolojik yapıya uygun olarak siper hatları oluşturulmuştur. Bu hatlar imkansızlıklar ve zaman kısalığından dolayı bir çok bölgede 1-1.30 metre derinliğinde hazırlanmış boy çukuru olabilecek alanlardır. Bu çalışmada savaş esnasında kullanılan ancak savaştan sonra sedimantasyon etkisi ile kaybolmaya yüz tutmuş siper hatlarının yer radarı (GPR) yöntemi ile belirlenmesi amaçlanmıştır. Yüksek frekanslı ve Geniş Band (80-950 MHz) GPR yöntemi ile uydu görüntülerinde takip edilebilen ancak yüzeyde izi kaybolmuş siper hattı boyunca 2 ve 3 boyutlu ölçümler alınarak siper hatlarının devamlılığı ve sedimantasyon sınırları başarılı bir şekilde tespit edilmiştir.
A era Lula, Celso Furtado e a economia política do crescimento com inclusão social
Authors: Lobo Vinicius Gomes , Pateo Felipe Vella
Published: August 2021

Este artigo visa ajudar a compreender melhor a Era Lula, um período em que ocorreu um intenso e surpreendente processo de inclusão social no Brasil. Para tal, são resgatados elementos da obra de Celso Furtado, porque em sua fase pós-estagnacionista a relação entre crescimento econômico e distribuição de renda ganha maior peso na sua análise e porque essa relação e os seus determinantes estiveram na base do processo inclusivo da Era Lula. Esse processo se baseou no aumento da renda ancorado no desempenho do mercado de trabalho, um processo claramente vinculado à dinâmica econômica. Porém, é importante destacar que tal desempenho vinculou-se não só à magnitude, mas sobretudo à forma como se expandiu a produção. É na definição do perfil de expansão (padrão de acumulação) e de sua influência sobre o mercado de trabalho que residem os principais determinantes da relação entre crescimento e distribuição, tão bem mapeados por Furtado.
Tecnologias sociais para políticas públicas de habitação no Brasil
Authors: Andrade Hugo Marcio Vieira de Almeida , Morais Leandro Pereira , Moraes Isaías Albertin de
Published: August 2021

O debate habitacional no Brasil foi retomado em um momento de forte demanda social, com ausência de políticas habitacionais nacionais e estaduais e oferta insuficiente da iniciativa privada para reduzir o déficit habitacional existente. O objetivo do artigo é mostrar que existem experiências importantes em tecnologias de habitação de interesse social (TS) já consolidadas no país e argumentar que as TS oferecem alternativas para o enfrentamento do problema habitacional. O argumento é dividido em duas seções. O primeiro fornece uma breve revisão teórica do conceito de TS; e a segunda trata da questão da habitação e das experiências listadas no Banco de Tecnologias Sociais (BTS) da Fundação Banco do Brasil (FBB). Em última análise, afirma-se que o TS pode aprimorar as estratégias de política governamental nessa área e são feitas considerações sobre os pontos básicos para sua inserção nas ações e políticas públicas de habitação no Brasil.
O ensino agrícola no Rio Grande do Norte (1910-1967)
Authors: Medeiros Neta Olívia Morais de , Lucas Marcelly Kathleen Pereira
Published: August 2021

Este trabalho tem como objetivo analisar as ações do Estado para o desenvolvimento do ensino agrícola no Rio Grande do Norte, bem como a influência das determinações legais nesse processo no período de 1910 a 1967.  Para isso, realizou-se mapeamento e análise documental das mensagens dos governadores do Rio Grande do Norte e dos relatórios do Ministério da Agricultura, os quais se constituem como fontes a esta investigação. O recorte temporal justifica-se pelo Plano Geral do Ensino Agronômico de 1910 e a transferência do ensino agrícola para o Ministério da Educação e Cultura. O referencial teórico baseia-se na concepção de educação profissional conforme Manfredi (2003) e na dimensão da história política de acordo com René Rémond (2003) e José D’Assunção Barros (2005). Com a análise, percebeu-se que o ensino agrícola, no período de 1910 a 1967, era definido pelas determinações do Ministério da Agricultura em suas diferentes denominações e organizações ao longo dos anos. E, no Rio Grande do Norte, as principais ações para o desenvolvimento desse ensino foram a implantação da Escola de Agricultura e Criação, o Campo de demonstração de Macaíba, os cursos ambulantes que eram ministrados no Campo, a Escola Agrícola de Jundiaí, o Curso de Especialização para o Serviço do Algodão, as Semanas Ruralistas e cursos e palestras ministrados nas visitas da Inspetoria Agrícola
