OBJECTIVE

To determine the clinical and pathological findings of rabbits diagnosed with lymphoma.

ANIMALS

16 rabbits.

PROCEDURES

The medical and pathology records database of the Veterinary Medical Teaching Hospital at the University of California, Davis was searched for rabbits diagnosed with lymphoma from 1996 to 2019.

RESULTS

Mean age of the 16 rabbits was 8 years (range, 4.5 to 12 years). Immunophenotyping was performed in 14 cases. Diffuse, large, B-cell lymphoma was most common (n = 7) followed by epitheliotropic, T-cell lymphoma (2); type II enteropathy-associated, T-cell lymphoma (2); marginal-zone, B-cell lymphoma (1); peripheral, T-cell lymphoma not otherwise specified (cutaneous nonepitheliotropic lymphoma; 1); primary, mediastinal (thymic) large B-cell lymphoma (1), and unclassified (cytology only with no immunophenotyping; 2). Multiple chemotherapy protocols were used on the basis of each individual animal’s disease state. Initial clinical improvement was reported for most rabbits receiving chemotherapy (5/6), with diffuse B-cell lymphoma responding most favorably to treatment. The 11 rabbits included in the survival analysis had a median survival time of 60 days (range, 1 to 480 days), and those diagnosed with B- and T-cell lymphoma had a median survival time of 8 and 36 days (range, 1 to 150 and 1 to 90 days), respectively.

CLINICAL RELEVANCE

Rabbits develop a range of lymphoma subtypes and, similar to humans and dogs, diffuse large B-cell lymphoma appears to be the most common. Chemotherapy treatments followed multiple protocols, which were mostly well tolerated and had a highly variable response. Further research into chemotherapy protocols is needed to optimize treatment of lymphoma in rabbits.
Long-term follow-up of a juvenile simple renal cyst in a dog treated by laparoscopic deroofing, fulguration, and omentalization
Authors: Dekerle Bastien , Fabres Virginie , Benchekroun Ghita , Manassero Mathieu
Published: March 2022

CASE DESCRIPTION

A 10-month-old male crossbred dog presented with a 4-week history of polyuria and polydipsia and a 6-month history of vomiting.

CLINICAL FINDINGS

Clinical examination revealed abdominal pain and right-sided nephromegaly. Biochemistry was within normal limits. Diagnostic imaging showed a well-defined, unilateral renal mass containing anechoic fluid consistent with a simple renal cyst (SRC).

TREATMENT AND OUTCOME

The cyst was drained under ultrasonographic guidance but recurred 3 months later, concomitant with recurrence of the previously reported clinical signs. The cyst was then deroofed, fulgurated, and omentalized under laparoscopy by use of a 3-port technique. The resected cystic wall was histopathologically consistent with an SRC, presumptively congenital. The dog showed a good recovery with resolution of clinical signs. Renal function was normal at last follow-up, conducted 2 years postoperatively, without evidence of recurrent disease.

CLINICAL RELEVANCE

To our knowledge, this was the first report of a symptomatic juvenile SRC of presumptively congenital origin in a dog treated successfully by laparoscopic deroofing, fulguration, and omentalization. The polyuria, polydipsia, chronic vomiting, and abdominal pain may all have been related to space-occupying effects of the cyst, as these symptoms resolved post-treatment. Results of long-term follow-up advocate for this durable cure of SRC by use of laparoscopic procedures, especially when compared to simple drainage of the cyst, as the latter initially failed in the present case.
Intestinal barrier disorders and metabolic endotoxemia in obesity: Current knowledge
Authors: Potrykus Marta , Szymański Michał , Kaska Łukasz , Janczy Agata
Published: March 2022

The World Health Organization reports that the prevalent problem of excessive weight and obesity currently affects about 1.9 billion people worldwide and is the fifth most common death factor among patients. In view of the growing number of patients with obesity, attention is drawn to the insufficient effectiveness of behavioral treatment methods. In addition to genetic and environmental factors leading to the consumption of excess energy in the diet and the accumulation of adipose tissue, attention is paid to the role of intestinal microbiota in maintaining a normal body weight. Dysbiosis – a disorder in the composition of the gut microbiota – is mentioned as one of the contributing factors to the development of metabolic diseases, including obesity, type 2 diabetes, and cardiovascular disorders. The human gastrointestinal tract is colonized largely by a group of Gram-negative bacteria that are indicated to be a source of lipopolysaccharide (LPS), associated with inducing systemic inflammation and endotoxemia. Research suggests that disturbances in the gut microbiota, leading to damage to the intestinal barrier and an increase in circulating LPS, are implicated in obesity and other metabolic disorders. Plasma LPS and lipopolysaccharide-binding protein (LBP) levels have been shown to be elevated in individuals with excess body weight. Bariatric surgery has become a popular treatment option, leading to stable weight loss and an improvement in obesity-related conditions. The aim of this study was to characterize the factors that promote the induction of metabolic endotoxemia and its associated health consequences, along with the presentation of their changes after bariatric surgery.
An analysis of lexicogrammatical development in English textbooks in Turkey: A usage-based construction grammar approach
Authors: Gedik Tan Arda
Published: March 2022

This article measures the syntactic development indices in grade 5-12 English textbooks in Turkey. Through a usage-based construction grammar approach, it argues that the textbooks show an inconsistent development in verb-argument constructions (VAC) and other usage-based indices. The study employs an automatic software tool that detects variations in these indices and runs a statistical analysis on a corpus compiled by the author. Statistically significant results demonstrate that textbooks lack lexicogrammatical variation. As such, learners who use these textbooks are likely to experience a limited array of VACs that are limited in lemma-construction combinations. Findings also indicate that learners may not be exposed to the conventional usage patterns and frequencies of VACs when compared against a reference corpus. These findings may have an influence on the learners’ generalization process, their low-proficiency level in English, and poor idiomatic uses of the language.
Intertextuality in media discourse: A reader’s perspective
Authors: Velykoroda Yuriy , Moroz Oksana
Published: March 2022

The article is a part of a research project on how intertextuality is perceived by readers of media texts. The focus of the article is on how intertextual references are recognized, interpreted, and substituted by EFL respondents. Based on the results of the survey, conclusions are drawn to address the following research questions – whether respondents can recognize intertextual references as such in the context, whether they can interpret an utterance despite failing to detect intertextual segments, and whether there exists a correspondence between recognizability of an intertextual reference and attempts at defining and/or replacing it. This paper is an attempt to empirically verify theoretical views on intertextuality. The results of the survey provide insights into how intertextuality is perceived by respondents.
Euphemistic strategies in Algerian Arabic and American English
Authors: Alghazo Sharif , Bekaddour Soumia , Jarrah Marwan , Hammouri Yazeed
Published: March 2022

This study aims to explore the use of euphemistic strategies by Algerians and Americans when dealing with three unpleasant topics: death, lying, and disease. It also examines the effect of degree of formality on the use of euphemistic strategies. To achieve this objective, a discourse completion task (DCT) was distributed to 21 Algerians and 21 Americans. The data were analysed using SPSS. The data analysis revealed that there are some differences and similarities between the two groups. The euphemistic strategies used by the Americans when they deal with death topics are synonyms and part for the whole. The Algerians use part for the whole, overstatement, and synonyms when they deal with death. Regarding the topic of lying, the Americans employ strategies of understatement and deletion, whereas the Algerians use understatement and metaphor. As for the topic of disease, the Americans use vagueness, and the Algerians use vagueness, metaphor, and deletion. These findings reveal that both groups resort to euphemism when dealing with these three unpleasant topics. However, their use of euphemistic strategies is culture-bound.
Provision of periurban zones of small towns of Kyiv region by forests as a factor of eco-stability
Authors: Yukhnovskyi Vasyl , Zibtseva Olha , Henyk Yaroslav
Published: March 2022

Humanity has come to the conclusion about the need for eco-balanced planning of territorial land use at both regional and local levels. The object of research is the periurban areas around 20 small towns of the Kyiv region – the most common category of cities in Ukraine. The provision of periurban areas of small towns with forests is analyzed taking into account three indicators: population in cities, distance to the nearest forests and their size. It was found that forests are absent in the vicinity of most small towns in the region which are mostly surrounded by arable land. Small towns are grouped into four clusters according to the similarity of forest provision of periurban zones with indicators: average (55% of towns); improved (Vyshhorod, Bucha); with the best situation (Irpin); worse (Vyshneve, Myronivka, Uzyn, Skvyra, Tetiiv, Yahotyn). Each such cluster requires the development of certain strategies for the formation of periurban green infrastructure, which will include both protective green stands and recreational areas. Therefore, around the small towns of Kyiv region it is recommended to immediately form periurban recreational and protective zones with a predominance of forests. This will dramatically improve the environmental situation and contribute to the environmental and social sustainability of urban areas.

Authors: O’Hara Jamie , Noone Declan , Kritikou Persefoni , Myren Karl-Johan , Chaplin Steve , Hart Daniel P
Published: March 2022

Background

Increasing survival among people with haemophilia means that more individuals are at risk of developing age-related morbidity. Little is known about morbidity and health-related quality of life (HRQoL) in different age groups within a single large population of people with haemophilia.

Aim

This study aimed to explore the association between increasing age and comorbidity among people with haemophilia and to compare their HRQoL with that of a sample of the general population in England.

Methods

The prevalence of comorbidity recorded in medical records and HRQoL assessed by EQ-5D were compared by age group in participants in the Cost of Haemophilia in Europe: A Socioeconomic Survey study (CHESS) in Europe. HRQoL was compared with that of a sample of the general population taken from the 2012 Health Survey for England (HSE).

Results

Younger adults in CHESS were more likely to have received prophylaxis from an early age. The mean number of affected joints in younger adults was 1.0; participants aged 41–50 (1.25) and 51–60 years (1.41) had the highest mean number of affected joints. The prevalence of comorbidity was 36% in patients aged 18–30, 61% in 31–60-year-olds and 68% in those aged 61+. HRQoL impairment in young adults with haemophilia was comparable with that in the HSE population aged over 60.

Conclusions

Older people with haemophilia have impaired quality of life compared with younger adults and an increasing prevalence of several age-related disorders affecting mental health and cardiovascular and bone health. Young adults with haemophilia report impaired HRQoL comparable with that in a general population aged 61+.
Key challenges for patient registries – A report from the 1st workshop of the EHC Think Tank Workstream on Registries
Authors: Bok Amanda , Noone Declan , Skouw-Rasmussen Naja , Tank Ehc Think
Published: March 2022

Introduction

Patient registries are an invaluable resource for furthering the understanding of rare diseases such as bleeding disorders, providing large, pooled datasets not achievable by other means of data collection. As well as supporting clinical care and research, registries must also be able to answer questions that are important to the wider bleeding disorders community. However, there are challenges associated with the need for secure access, exchange of health data, quality and interoperability, and data delivery.

Identifying key challenges

As part of the EHC Think Tank Patient Registries Workstream, 17 stakeholders representing health care providers, patient groups, research and industry met in October 2021 to identify challenges to managing and utilising patient registries, from each of their stakeholder perspectives. This is a first step in a longer term process aiming to identify or co-create solutions that could improve access and interpretation of patient data. The challenges identified relate to five key categories which are interlinked in various ways: 1. The multiplicity of registries and datasets; 2. Data quality; 3. Data sharing; 4. Expanding the scope of registries; 5. The role of the patient in registries.

The heterogeneity in the way that registries are designed, funded and owned, the type of data collected, and the way data is collected are issues that must be addressed. Good, quality data is needed at all levels to ensure the provision and funding of effective care. Data quality will increase overall if it is possible to merge data from different registries. The value of patient participation in registries must also be acknowledged and built on to help ensure their quality, that they remain fit for purpose, and that data input is sustained over time.

Authors: Saidu Abubakar M. , Fadason Samuel T. , Ochube Gabriel E. , Adamu Sani
Published: March 2022

Standing and lateral recumbency positions have been used as a standard approach for most surgical procedures for large and small ruminants, respectively, without appropriate attention to the associated surgical stress. The study aimed to assess the level of surgical stress in Kano Brown goats (KBGs) based on their serum amyloid A (SAA) profiles by undergoing rumenotomy in lateral recumbency (Rumen Skin Clamp Fixation-RSCF and Stay Suture Rumenotomy-SSR) and a standing position restraint. A total of 24 KBGs were equally allocated by number and sex in groups A, B, C, and D. Groups A and B underwent RSCF and SSR in lateral recumbency, respectively, while group D underwent a rumenotomy in a standing position performed in a custom made mobile small ruminant surgical chute. Animals in groups A, B, and D were diagnosed with rumen foreign bodies, whereas group C was used as a control with a negative diagnosis. At 48 h post-rumenotomy, the mean SAA concentration in group B (137.88±66.87 g/L) was significantly higher (P<0.05) than the value in group C (34.59±0.57 g/L). The females in group B had a significantly higher (P<0.05) mean concentration of SAA at 48 hours (210.15±123.73 g/L) than groups C (35.18±0.08 g/L) and D (48.35±12.15 g/L). In group A, at 24 hours, SAA concentration (115.61±20.96 µg/L) was significantly higher (P<0.05) than that of group B (31.51±2.59 µg/L) and group C (34.86±3.21 µg/L) in males. Rumenotomy in the standing restraint position was associated with minimal surgical stress, hence it’s recommended over the conventional lateral recumbent position techniques.

Published: March 2022

Background/Purpose: Entrepreneurial education can have a positive effect on entrepreneurial intention of university students, yet universities in Jordan still do not direct their attention to invest in Entrepreneurial education. This study aims to investigate the effect of entrepreneurial education and Culture on entrepreneurial intention through psychological empowerment of university students.

Methodology: A questionnaire was distributed to a sample of 220 university students in Jordan who take any course in entrepreneurship. Data were analysed and hypotheses were tested through Structural Equation Modelling (SEM) using Statistical Package for Social Sciences (SPSS).

Results: The analysis of the study showed that; entrepreneurial education has a significant influence on psychological empowerment, psychological empowerment has a significant influence on entrepreneurial intentions, culture has a significant influence on psychological empowerment, entrepreneurial education has a significant influence on entrepreneurial intention and culture has a significant influence on entrepreneurial intention. The results of the study answer the calls of previous research to examine the role of culture and psychological empowerment in entrepreneurial education to affect entrepreneurial intention.

Conclusion: Universities in Jordan should focus more on entrepreneurial education by psychologically empowering students to increase their intentions towards entrepreneurship. This study contributes to the existing literature by providing a better understanding of the relationship between entrepreneurial education and entrepreneurial intention through culture and psychological empowerment.

Authors: Knezović Emil , Smajić Hamza
Published: March 2022

Purpose: The purpose of this article is to examine the relationship between employee participation in the decision-making process (EPDMP) and organizational citizenship behavior (OCB) while considering the mediating role of affective commitment (AC).

Methods: The article is based on primary cross-sectional data collected using questionnaires and applying a convenience sampling method among employees in Bosnia and Herzegovina (B&H). The sample consists of 302 employees from 127 companies across multiple industries.

Results: First, there is a positive relationship between EPDMP and two dimensions of OCB – organizational citizenship behavior directed at individuals (OCBI) and organizational citizenship behavior directed at the organization (OCBO). Second, the findings suggest that AC mediates the relationship between EPDMP and OCBI and OCBO. Furthermore, OCBI is found to mediate the relationship between AC and OCBO.

Conclusion: This article extends the literature by introducing the mediating role of AC in the relationship between EPDM and two dimensions of OCB and the mediating role of OCBI in the relationship between AC and OCBO.
Predicting HR Professionals’ Adoption of HR Analytics: An Extension of UTAUT Model
Authors: Ekka Susmita , Singh Punam
Published: March 2022

Background and Purpose: To scale up HR innovation with HR technology, organizations worldwide are putting effort into adopting HR Analytics (HRA) among HR professionals and the actual use of HRA for organizational decision-making. This study aims to explore the behavioral intention to use HRA from the perspective of HR professionals by using UTAUT.

Methodology: Partial least squares structural equation modeling (PLS-SEM) was employed to validate the model based on data collected via a survey from 270 HR professionals in India.

Results: The result revealed a significant positive impact of performance expectancy, effort expectancy, social influence, and facilitating condition on behavioral intention to use HRA. However, organization culture negatively moderates the relationship between HRA adoption intention and adoption behavior. The establishment of organizational culture as a moderator in Indian organizations is unique.

Conclusion: The study extends the explanatory context of UTAUT and provides feasibility for the organizations to guide HR professionals to adopt HRA from multiple paths of intention and usage behavior. Managers, business leaders, and policymakers can use this finding to assist HRA adoption in their organizations.

Published: March 2022

OBJECTIVES. As a person ages, the mucosal epithelium degenerates over time and the elderly often have complications due to dehydration. Nasal airflow decreases and nasal airway resistance increases. In this review, we discuss the relationship of rhinitis, sinusitis and asthma in elderly patients.

MATERIAL AND METHODS. The literature survey was performed using the search engines PubMed, Google, Proquest Central, and EBSCO at the Kırıkkale University Library.

RESULTS. With the aging process, allergic rhinitis decreases, whereas non-allergic rhinitis, such as drug-induced rhinitis can be observed more. Atrophic rhinitis is often seen in the elderly. Patients with geriatric rhinitis typically complain of constant sinus drainage problems, which may cause sinusitis. In addition, asthma prevalence has also been shown to be higher in elderly patients. Concurrent upper (rhinitis) and lower (asthma) respiratory tract symptoms are defined as Combined Allergic Rhinitis and Asthma Syndrome.

CONCLUSION. Rhinitis and asthma as well as sinusitis and asthma may be present in elderly patients. The incidence of allergic rhinitis has been shown to decrease with age. To achieve good results from treatment, the concurrent rhinitis and asthma as well as sinusitis and asthma should be kept in mind in elderly patients.
Moral Dilemma in Education of Baduy Community
Authors: Nurrochsyam Mikka Wildha
Published: March 2022

Dewasa ini masyarakat Baduy mengalami dilema moral dalam pendidikan. Dilema moral terlihat dari dua pilihan yaitu di satu sisi sekolah ditolak karena dianggap bertentangan dengan adat atau tradisi. Orang Baduy yang bersekolah terbukti banyak yang meninggalkan tradisi dan adat Baduy. Di sisi lain sekolah diterima karena menjadi sarana untuk mencapai kehidupan yang sejahtera. Penelitian ini bertujuan untuk mendeskripsikan dilema moral pendidikan dalam masyarakat Baduy yang terbagi atas masyarakat Baduy Dalam dan Baduy Luar serta merumuskan jenis pendidikan yang sesuai dengan budaya mereka. Penelitian ini merupakan penelitian kualitatif, dengan menggunakan metode studi kasus. Data-data diperoleh dari wawancara mendalam dengan para informan sedangkan analisis penelitian menggunakan analisis kritis. Hasil penelitian menunjukkan bahwa masyarakat Baduy menempati tingkat kesadaran moral konvensional, yaitu moralitas kelompok menjadi ukuran kebaikan, hasil penelitian juga menunjukkan bahwa terdapat orang-orang yang kritis yang menempati tingkat kesadaran pasca konvensional. Berdasarkan atas tingkat kesadaran moral ini maka jenis pendidikan yang sesuai dengan budaya masyarakat Baduy Dalam adalah pendidikan nonformal yang diorientasikan untuk memperkuat adat dan tradisi; dan bagi masyarakat Baduy Luar jenis pendidikan yang sesuai adalah pendidikan formal yang diorientasikan untuk kesejahteraan hidup komunitas.

Baduy community nowadays experiences a moral dilemma in education. The moral dilemma can be seen from two choices, where on one side, the school was rejected because it was considered to be contrary to custom or tradition. Many of the Baduy people who go to school leave the traditions and customs of Baduy. On the other hand, the schools welcomed because they become a means to achieve a prosperous life. This research aims to describe the moral dilemma in the education of the Baduy community, which is divided into Baduy Dalam and Baduy Luar communities, and formulate the types of education following their culture. This is qualitative research using a case research method. The data were obtained by conducting in-depth interviews with informants, while the analysis method used was critical analysis. Results of the research indicated that Baduy people occupied the conventional moral awareness level, namely group morality, as a measure of goodness. The results also indicated that critical people occupied the post-conventional awareness level. Based on this moral awareness level, then the type of education following the culture of the Baduy Dalam community were non-formal education oriented to strengthen the customs and traditions. At the same time, the appropriate type of education for the Baduy Luar community was formal education oriented to the community's welfare.

Published: March 2022

No estado do Ceará, encontram-se definidos três núcleos de desertificação ou Áreas Susceptíveis à Desertificação – ASDs (Sertões de Irauçuba e Centro-Norte, Sertões dos Inhamuns e Sertões do Médio Jaguaribe). Essas áreas são foco de uma série de estratégias voltadas para combater o fenômeno, sendo a mais relevante a elaboração do Programa de Ação Estadual de Combate à Desertificação e Mitigação dos Efeitos da Seca – PAE-CE. Diante disso, o objetivo do estudo é caracterizar a desertificação na região dos Inhamuns. Para tanto, foram utilizados dados primários obtidos por aplicação de formulários, em janeiro de 2018, junto a lideranças de comunidades rurais localizadas nos Municípios de Arneiroz, Independência e Tauá, inseridos na ASD. Como procedimentos metodológicos, inicialmente, foi adotada a metodologia PER (Pressão-Estado-Resposta) para descrever a situação da desertificação na região com suporte em um conjunto de indicadores. Os principais resultados mostraram que os indicadores de estado são os que mais determinam a desertificação na região. A maior parte das comunidades encontra-se em um nível intermediários de desertificação.
INVASÃO DE DADOS POR DISPOSITIVOS ONLINE E ASSISTENTES VIRTUAIS E SUA VALIDADE COMO MEIO DE PROVA NO PROCESSO PENAL BRASILEIRO
Authors: Orsi Ana Claudia Bosrsato , Dorigon Alessandro Morgado
Published: March 2022

Objetivou-se com o presente trabalho analisar se os dados obtidos por dispositivos on-line e assistentes virtuais, estes dotados da inteligência artificial, seriam válidos no âmbito processual penal brasileiro como meio de prova em um processo crime. Embora a virtualidade possa ser enquadrada aos demais ramos do direito, interessou-se desenvolvê-la no processo penal, pois, ao considerar que para seu pleno funcionamento, esses dispositivos devem ficar constantemente ligados e conectados a uma rede de internet, gravando o ambiente à espera de uma palavra de ativação, surgindo a dúvida se essa gravação é válida como meio de prova no processo crime. Nesses termos, por ser um meio de obtenção que viola a intimidade do usuário, tem-se uma linha tênue entre a necessidade da prova e a indispensável proteção de dados. Para tanto, a Lei n°. 13.709/2018, conhecida como Lei Geral de Proteção de Dados, disciplina por meio de normas e princípios a preservação da privacidade virtual. Neste sentido, embora quase não utilizado no direito pátrio, para que os dados obtidos por meio de dispositivos on-line e assistentes virtuais, sejam lícitos como prova, o usuário deve ter pleno conhecimento de sua obtenção, assim como expressamente cedê-los, se comprovado a finalidade e necessidade da prova, deverá ser cedido através da autorização judicial. Para o desenvolvimento do presente, a pesquisa bibliográfica se respaldou doutrinas, artigos, dissertações jurisprudências e textos de lei.
Mejoramiento de las propiedades físico -mecánicas del suelo con incorporación de asfalto para elaborar adobes
Authors: Ramirez Chuquizuta Olinda Llisela
Published: March 2022

El objetivo de la investigación fue evaluar la variación de las propiedades físico-mecánicas del adobe al adicionar emulsión asfáltica al 2%, 4% y 6%. Se elaboraron un total de 96 bloques de adobe (24 adobes tradicionales, 24 adobes con 2% de asfalto, 24 adobes con 4% de asfalto y 24 adobes con 6% de asfalto), dichos bloques fueron sometidos a ensayos a la resistencia a la compresión, resistencia a flexión, absorción y saturación total. De los ensayos de laboratorio se consiguió una resistencia a compresión de 15,34 kg/cm2 correspondiente a las unidades de adobe con 6% de asfalto, en los ensayos de resistencia a flexión se obtuvo un valor máximo de 3,36 kg/cm2; ambos valores superiores con respecto a lo obtenido con los adobes tradicionales. En los ensayos de absorción se registró que las unidades de adobe con 6% de asfalto disminuyó hasta un 29% el porcentaje de absorción sobre los adobes convencionales, se observó también que los adobes con adición de asfalto presentan menor desgaste. Se concluye que la incorporación de asfalto a los bloques de adobes convencionales mejora las propiedades físico-mecánicas de éstas.

Published: March 2022

El objetivo de esta investigación fue evaluar los índices de deforestación ocurridos en el distrito de Yambrasbamba, región Amazonas Perú, entre los años 1987 y 2019, en dos periodos, P1 (1987-2001) y P2 (2001-2019), mediante técnicas de teledetección. Se utilizó material cartográfico, imágenes satelitales y software de sistemas de información geográfica (SIG) y se realizó una clasificación supervisada en la que se consideró las siguientes clases: Áreas artificializadas (AA), pastos y cultivos (PC), tierra desnuda (TI), bosques (BO) y una clase adicional de nubes y sombras (NS). La efectividad de la clasificación fue evaluada con el coeficiente de Kappa para determinar el grado de concordancia que hubo entre los mapas temáticos y la realidad. Mediante matrices de error se evaluaron cambios de uso de suelo, índices de deforestación y las transiciones por cada clase. Los resultados mostraron que hubo un aumento de extensión de las clases AA y PC, producto de actividades antropogénicas lo que originó una considerable disminución de la clase BO. Se concluye que existe la misma tendencia en los dos periodos evaluados.

El objetivo de la presente investigación fue determinar la actividad bactericida del extracto etánólico de Aloysia citridora “cedrón” en bacterias alteradoras de carne. Se utilizó como muestra biológica carne fresca (vacuno, pollo y pescado). Se preparó el extracto etanólico utilizando 100g de hoja triturada con un litro de etanol, macerado por 8 días a temperatura ambiente. El filtrado de la maceración se sometió a evaporación por 72 horas a 42 °C. Se trabajó con un grupo control (10g de carne y 90 ml de agua destilada) y un grupo experimental (10g de carne y 90 ml de extracto etanólico), luego se procedió a las siembras microbianas. Se encontró que el halo de inhibición promedio, de crecimiento para Staphylococcus aureus fue de 12mm, lo que demuestra la propiedad antibacteriana de Aloysia citridora para Staphylococcus aureus, además se observó inhibición de crecimiento bacteriano en agar Macconkey y agar nutritivo, en los grupos experimentales, mientras que en el grupo control se observó crecimiento. Respecto a los recuentos en agar nutritivo el mayor valor fue de 1.21x103 ufc/ml para el grupo control con carne de pollo. Se concluye que el extracto etánólico de Aloysia citridora tiene actividad bactericida en Escherichia coli y Staphylococcus aureus, bacterias alteradoras de carne fresca.

El objetivo de la presente investigación fue determinar los impactos ambientales en fincas de cacao mediante el balance de carbono y nutrientes del suelo, en las provincias de Utcubamba y Bagua en la región Amazonas, Perú. Se realizó una entrevista con el productor cacaotero para obtener información específica del manejo del cultivo de cacao en sus diferentes etapas de producción, proceso y transformación. Se recolectó muestras de suelos para hacer un análisis físico químico y de esta manera demostrar experimentalmente la disponibilidad de nutrientes que tiene las plantaciones de cacao. Se encontró que las fincas cacaoteras emiten 1.83 t CO2/ha siendo la mayor fuente de emisión la mala gestión de sus residuos vegetales (44%), seguido de la aplicación de fertilizantes (33%), el transporte fuera de la finca (17%), uso de energía en el procesamiento (5%) y por último la protección de los cultivos (1%).  Se concluye que los procesos que tienen un impacto positivo en el balance total de emisiones de carbono son los cambios en la reserva de carbono por medio del sistema agroforestal que presentan las fincas, teniendo un flujo de fijación de carbono de 1.48 t C/ha/año.

A novel hit molecule, an alpha-glucosidase inhibitor has been discovered in a set of diarylsulfonylureas (C1- C8). Their syntheses, characterization as well as in vitro bioassay screening data have been reported. Based on the results obtained in kinetic enzymatic studies, compound C2 was identified as a competitive inhibitor with an IC50 value of 22.99 ± 1.08 μM whereas other compounds were found to possess lower order potency, relatively no activity. Compounds C2 that exhibited discriminative potency among the series, might be used for “hit optimization” in our further investigation towards developing powerful antidiabetic agents.

В данной статьеавтор говорит о рациональном использовании дождевых и талых вод, которые почти нигде неиспользуются. Проблемы, связанные с рациональным использованием водных ресурсов, чистой воды и охраны водных экосистем становятся все более острыми по мере исторического развития общества, стремительно увеличивается влияние на природу, вызываемого научно-техническим прогрессом.Известно, то, что годовые осадки различных регионов земного шара составляют от 100мм до 800ммпо вертикальной оси.Это значит, что на 1м2 земли масса дождевых и талых вод в год составляет от 100 до 800 литров. Рассмотрены теоретические предпосылки аккумуляции дождевых и талых вод в местах, которые страдают нехваткой водных ресурсов.

In this article, the author talks about rational use of rainwater and meltwater, which is almost never used. Problems related to the rational use of water resources, clean water and protection of water ecosystems are becoming more acute as the historical development of society, rapidly increasing impact on nature caused by technological progress. It is known that annual precipitation in different regions of the globe range from 100 mm to 800 mm on the vertical axis. This means that 1m2 of the land mass of rain and melt water amounts from 100 to 800 liters. The theoretical accumulation of rainwater and meltwater in areas which suffer from water scarcity.

Trade-off between redox potential and strength of electrochemical CO2 capture in quinones
Authors: Bui Anna T. , Hartley Niamh A. , Thom Alex J. W. , Forse Alexander C.
Published: March 2022

Electrochemical carbon dioxide capture has recently emerged as a promising alternative approach to conventional energy-intensive carbon capture methods. The most common electrochemical capture approach is to employ redox-active molecules such as quinones. Upon electrochemical reduction, quinones become activated for the chemical capture of CO2. The main disadvantage of this method is the possibility of side-reactions with oxygen, which is present in almost all gas mixtures of interest for carbon capture. This issue can potentially be mitigated by fine-tuning redox potentials through the introduction of electron-withdrawing groups on the quinone ring. In this article, we investigate the thermodynamics of the electron transfer and chemical steps of CO2 capture in different anthraquinone derivatives with a range of substituents. By combining density functional theory calculations and cyclic voltammetry experiments, we discover a trade-off between redox potentials and the strength of CO2 capture. We show that redox potentials can readily be tuned to more positive values to impart stability to oxygen, but as a consequence, significant decreases in CO2 binding free energies are observed. This trade-off must be taken into consideration for the design of improved redox active molecules for electrochemical CO2 capture.
Activation of H2O tailored by interfacial electronic states at nanoscale interface for enhanced electrocatalytic hydrogen evolution

Published: March 2022

Despite the fundamental and practical significance of the hydrogen evolution reaction (HER), the reaction kinetics at the molecular level is not clear, particularly in basic media. Here, with ZIF-67 derived Co-based carbon frameworks (Co/NC) as a model catalyst, we systematically investigated the effects of different reaction parameters on the HER kinetics, and surprise found that HER activity was not directly dependent on the type of nitrogen in the carbon framework, but on the relative content of surface hydroxyl and water (OH-/H2O) adsorbed on Co active sites embedded in carbon frameworks. When the ratio of the OH-/H2O was close to 1:1, Co/NC nanocatalyst showed the best reaction performance under the condition of high-pH electrolytes, e.g., with an overpotential of only 232 mV at a current density of 10 mA cm-2 in 1 M KOH electrolyte. We unambiguously identified that, the structural water molecules (SWs) in the form of hydrous hydroxyl complex absorbed on metal centers {OH-∙H2O@M+} were catalytic active sites for enhanced HER, where M+ could be transition and/or alkaline metal cations. Different from the traditional hydrogen bonding of water, the hydroxyl (hydroxide) groups and water molecules in SWs were mainly transiently bonded together through the spatial interaction between the p orbitals of O atoms, showing characteristics of delocalized π bond with dynamic feature. These new formed surface bonds or transient states could be a new weak interaction, which can act as an alternative channel for concerted electron and proton transfer at electrode surface. The capturing of new surface states not only answers pH-, cation- and transition metal- dependent hydrogen evolution kinetics, but also provides completely new insights into the understanding of other electrocatalytic reduction involved by other small moleculesm, including CO2, CO and N2 etc.
