El enredo en las artes de pesca es reconocido como la principal amenaza moderna para las poblaciones de cetáceos a nivel mundial. A continuación, se presenta la primera evidencia de interacciones entre las pesquerías artesanales marino-costeras y los cetáceos a lo largo de la costa del Pacífico de El Salvador. Entre los años 2017 y 2022, se registraron cinco eventos de enredo, dos en especies de delfines oceánicos, Stenella longirostris y S. attenuata, tres casos de ballenas jorobadas, Megaptera novaeangliae, uno de ellos fue una madre y una cría dependiente, enredadas en el mismo arte de pesca. Estos cinco incidentes fueron documentados en el oeste de El Salvador, cerca del Puerto de Acajutla y constituyen el primer informe de enredo de cetáceos en el país, incluyendo un caso que afecta a una población de ballenas migratorias en peligro de extinción y a una especie de delfín amenazada. Cabe destacar que, dos casos de animales vivos enredados involucraron intentos/exitosos de liberación de los animales por parte de pescadores locales voluntarios, guardarrecursos y personal de la fuerza naval no entrenados en el rescate de cetáceos. Este informe destaca la necesidad de gestionar y mitigar las interacciones de la pesca con los cetáceos en El Salvador, incluyendo la formación de los equipos de rescate, para reducir la amenaza de enredo de los cetáceos y el riesgo para la vida humana durante los intentos de rescate.

Este artículo trata de la reconstrucción paleoartística de algunos representantes clave en la historia evolutiva de los cetáceos: Pakicetus attocki, Protocetus atavus, Zygorhiza kochii, Basilosaurus isis y Mystacodon selenensis contrastaron con representaciones antiguas de estos animales para reflejar los cambios que han traído las publicaciones científicas recientes en cuanto a su anatomía y otros aspectos ecológicos que nos ayudan a comprender mejor a estos animales.
Mixomicetes asociados con Avicennia germinans y Laguncularia racemosa en un manglar de El Salvador
Authors: Morales-Hernández Ricardo , Rojas-Alvarado Carlos
Published: March 2023

Los estudios de mixomicetes en ecosistemas de manglar no son comunes; principalmente se han llevado a cabo en Brasil. En esta investigación, se realizó el primer muestreo de mixomicetes asociados a dos especies de plantas de manglar en El Salvador, y por extensión, en Centroamérica. Para ello, se recolectó material vegetal en descomposición en el campo y se aislaron los microorganismos con la técnica de cámara húmeda. Con un esfuerzo de 60 muestras de campo, se registraron 17 especies de mixomicetes, de las cuales 11 no habían sido previamente comunicadas para los ecosistemas de manglar a nivel mundial según la literatura revisada. Estos resultados mostraron que, si bien la presencia de mixomicetes en manglares era previamente conocida, la diversidad de especies asociadas a estos ecosistemas todavía es poco estudiada. Además, el estudio mostró que los manglares centroamericanos albergan especies diferentes a las presentes en los manglares de Sudamérica. Se requieren más estudios en la región centroamericana para evaluar las razones.

Published: March 2023

El presente documento es un resumen de la sustentabilidad bioclimática en el edificio administrativo de la Facultad de Ingeniería y Arquitectura junto con la aplicación de la norma ISO50001. La cual sugiere la utilización de recursos naturales de manera sostenible junto con sistemas de construcción adecuados para conseguir el mínimo impacto ambiental tanto en la naturaleza y en las personas. También, preservando el medio ambiente para futuras generaciones y siendo capaz de autorregularse térmicamente sin necesidad de aparatos tecnológicos. Se realiza un modelaje en SketchUp y simulación en OpenStudio y EnergyPlus para caracterizar el consumo de energía del edificio e identificar y analizar los aspectos de mejora de este. A su vez, se compara dicha simulación con los resultados obtenidos de mediciones de consumo energético en el edificio, corroborando la validez de los resultados de la simulación. Por lo que, con enfoque en la eficiencia energética y el confort térmico, se propone la sustitución de los actuales aires acondicionados por unos de tecnología inverter, la instalación de cortasoles en las fachadas de los edificios, sustitución de luminarias actuales por unas de tecnología LED, siembra y mantenimiento de vegetación circundante al edificio, y la concientización del personal del edificio a través de capacitaciones de gestión y cultura del ahorro de energía. De esta manera, se estima un ahorro significativo de hasta 7,586 kWh anualmente, que puede representar cerca de USD$1,140.00 anuales (tarifa media de cargo de energía de USD$0.15/kWh).

Study of Influential Mechanism of Workplace Loneliness and Knowledge Hiding
Authors: Zhang Xuelin
Published: March 2023

In the digital era, enterprises need a series of innovative practices to stand out in the fierce market competition. The role of unique intellectual resources is particularly important in maintaining competitive advantages compared to other replicable production resources. Knowledge is an intangible asset that requires a people carrier in order to be used and circulated in organizations, innovation is often born in this process. Managers have invested a lot of resources to facilitate knowledge sharing, but to protect their personal interests, employees may implement knowledge hiding to maintain their own assets and unique status, so that making knowledge management practices have little effect in organizations. Knowledge hiding behavior has gradually become a topic of academic concern in the field of knowledge management. In this era, the epidemic has further driven changes in employees' work environment and methods, reducing human contact and giving rise to workplace loneliness. In recent years, domestic scholars have also begun to pay attention to this negative emotional experience in the workplace and have conducted studies on negative work behaviors triggered by workplace loneliness. In this study, we focus on the mechanism of workplace loneliness on knowledge hiding behavior and construct a research model based on the resource conservation theory and the job demands - resources model. Specifically, workplace loneliness is used as the independent variable to influence knowledge hiding through the mediating effect of emotional exhaustion, and high involvement work system is introduced as the boundary condition to verify its moderating effect on the first and second stages of the model.

Authors: Yang Bo , Wei Junjiao
Published: March 2023

In order to better improve the development of logistics industry in provinces and cities along the new land-sea channel under the background of "double carbon", and improve the efficiency of green logistics. Based on the logistics data of 13 key provinces and cities along the new land-Sea corridor from 2011 to 2020, this paper takes carbon dioxide emissions as unwanted output to build a green logistics efficiency evaluation system. Through the super-efficiency SBM model, the annual static green logistics efficiency of the logistics industry in each province and city is obtained, and the dynamic change of the regional green logistics efficiency compared with the previous year is measured by the Malmquist index model. The results show that: from 2011 to 2020, the green logistics efficiency of provinces and cities along the new land-Sea corridor showed a small trend of upward fluctuation, and the differences of logistics efficiency under the constraint of carbon emission were obvious, and the logistics efficiency of western provinces and cities had a large room for improvement. This paper puts forward suggestions to effectively improve the efficiency of green logistics, aiming to provide decision-making basis for the government to develop low-carbon economy in the logistics industry.

Research on Sino-British Trade Efficiency and Potential
Authors: Zhu Xuejun , Ma Dongfen
Published: March 2023

On the basis of analyzing the bilateral trade combination, export concentration and complementarity between China and the UK, a stochastic frontier gravity model is used to measure the trade efficiency and potential between China and the UK, and a realization path for China-UK trade cooperation is proposed. It is found that: the bilateral trade volume between China and the UK is steadily increasing, but the growth of UK exports to China is sluggish and the trade deficit is expanding year by year; the trade links between China and the UK are relatively loose, but there is a trend of strengthening; the trade products are more complementary and the types of trade complementary goods between the two countries do not overlap; but the export concentration is high. The trade potential between China and the UK is expanding year by year, reaching 224.9 billion USD by 2019; trade efficiency is steadily increasing, but is significantly constrained by tariff barriers and average turnaround time of imports, while financial and commercial liberalization can significantly improve the trade efficiency between the two countries. It is recommended to strengthen cooperation with the UK in the financial sector, expand imports of service products to the UK, and promote the construction of a free trade zone between the two countries at an appropriate time.

Authors:   Shri Shankaracharya Technical Campus, Bhilai (Chhattisgarh), India, Yadav Pradeep Singh , Jain Harsha ,   Shri Shankaracharya Technical Campus, Bhilai (Chhattisgarh), India
Published: March 2023

Due to the substantial impact embedded Static Random Access Memory (SRAM)s have on the overall system and their relatively limited design, it is essential to manage embedded SRAM trade-offs strategically. SRAMs have power, performance and density trade-offs in general. In all applications, all three dimensions are necessary to some extent; accordingly, embedded SRAM design must incorporate the most crucial system-specific requirements when developing embedded SRAM. This paper discusses many SRAM factors, including Static Noise Margin (SNM), Read Access Time (RAT),Write Access Time (WAT), Read Stability and Write Ability, Power, Data Retention Voltage (DRV), and Process Control. All these factors are crucial when designing SRAM for embedded memory applications. There has also been a discussion of the parameter comparisons and the literature review of the current papers.

The current study was designed to evaluate the impact of smoking status and cessation in bladder carcinoma patients undergoing radial cystectomy. A prospective study was conducted in the Department of Urology and Radiation Oncology of Shifa International Hospital, Islamabad and MMDC, Multan from January 2022-January 2023. A total of 190 patients with urothelial carcinoma of the bladder undergoing radial cystectomy were included in the study. Smoking history was noted for each patient before radial cystectomy. This history included smoking status, quantity, duration, and cessation in patients with former smoking history. The mean age of patients was 65.3 years. Among 190 patients, 87 were former smokers, 65 were current, and 38 were non-smokers. 58 patients (30.5%) had a pathological tumor stage 3. Multivariate analysis showed that duration of smoking, smoking cessation, and cumulative smoking exposure were predictors of tumor staging. Patients with more than 30 years of smoking were at higher odds of developing advanced tumor stage. Similarly, increased cumulative exposure was associated with greater odds of high tumor stage (p<0.001). Duration of smoking cessation had an opposite relationship with the odds of advanced tumor (p=0.001). Based on the results, it can be concluded that the current smoking status and cumulative smoking exposure are directly associated with disease development and recurrence in urothelial carcinoma of bladder patients. Smoking cessation has the opposite relationship respectively.

Published: March 2023

This study aimed to assess risk factors that predict the length of stay and 30-day mortality in subjects undergoing CAGB to evaluate the impact of IABP support in patients with low ejection fraction. The prospective study was conducted in the Cardiology Department of Punjab Institute of Cardiology Lahore from January 2022 to January 2023. A total of 315 patients were included in the study. The sample was divided into a study group (n=110, having LVEF ≤ 30%) and a control group (n=205, having EF > 30%). Pre-operative and intraoperative data of the patients were recorded. Post-operative complications were recorded, including LOS in the hospital and 30-day mortality. Patients in the study group required more emergency CABG ( P = .005), and IABP was also used more frequently in patients having EF< 30% (P<.001). LOS in hospital (P<.001) and ICU (P<.001) and 30-day mortality (P=.009) were higher in the study group. According to multivariate logistic regression analysis, in the study group history of cerebrovascular disease ( P = .018), peripheral vascular disease ( P = .004), congestive heart failure ( P = .027), and IABP use ( P = .002) were associated with the rate of 30-day mortality. Moreover, the increased length of hospital stay in these patients was associated with an increase in age (P<.001), hypertension (P=.040), and IABP use (P=.009). Based on the results, it can be concluded that the low ejection fraction positively affects increased LOS and 30-day mortality in subjects undergoing CABG; IABP insertion is a significant predictor of increased LOS and 30-day mortality and increases post-operative complications.

Utilizing technology to enhance students' writing skills at the higher education level is now the focus of scholars. One of the most effective nontraditional approaches to enhancing pupils' writing abilities is vlog-assisted language learning (VALL). The university professors who instruct pupils on writing skills never use this VALL. Therefore, the purpose of this study is to compare the academic writing skills of first-year university students taught utilizing the methodology of Bog-Assisted Language Learning (VALL) with those who were not. In addition, this research analyzes how students react to using VALL in teaching and learning writing skills. Thirty university English majors in their third year participated in the research. The research took a quantitative approach to data collection by administering pre- and post-writing examinations and a series of questionnaires to both the experimental and control groups. Evaluation of the gathered data was carried out with the use of descriptive statistics. The findings indicated that pupils who were taught writing utilizing VALL improved substantially more than those that were not. In addition, most student responses on using VALL to teach writing skills were favorable. Since this is the case, the English Department at a university might benefit from implementing VALL into their teaching and learning of writing.
Can I Trust You?

Adolescence is an important developmental period for learning who can and cannot be trusted, and how to adapt one’s trust behavior in response to others’ reciprocal behavior. The main objective of this thesis was to create more insight into the development of adolescent trust behavior and to explain individual differences in trust behavior and the related neural activity. The development of initial trust behavior and the development of adaptive trust behavior were investigated. Furthermore, in the chapters described in this thesis, factors within the individual, e.g., gender, personality traits, symptoms of psychopathology, and perspective-taking abilities, and factors from one’s social environment, e.g., social embeddedness within social networks, were used to predict individual differences in trust behavior.
Collectively, the results presented in this thesis indicate that adolescence is an important developmental period for trust behavior. First, increased levels of initial trust behavior were found throughout adolescence. Second, adolescents showed stronger adaptive trust behavior with age when interacting with untrustworthy others, and they showed age-related increases in average trust behavior when the partner behaved in a trustworthy manner. This suggests that learning who can be trusted and responding adaptively to the partner develops throughout adolescence. Adaptive trust behavior was also elicited by contextual factors, as adolescents showed they were able to overcome incorrect prior expectations about the partner and adjust their trust behavior in response to the partner’s actual behavior. The increased dlPFC and superior parietal gyrus activity that was found when interacting with this partner might tentatively suggest that cognitive control processes underlie these adaptive trust behavior processes. Furthermore, the results of this thesis indicated no support for a relationship between trust behavior and personality traits, symptoms of psychopathology, and perspective-taking abilities. The results did show that individual differences in adolescent trust behavior and the related neural activity can be explained by gender and the position within a social network. Boys showed a stronger developmental increase in initial trust behavior throughout adolescence compared to girls. Furthermore, the centrality of one´s social network position was positively related to levels of initial trust and to caudate activity, tentatively indicating increased expectancy violation when interacting with untrustworthy others.

Artemisia absinthium, also known as wormwood, is used in traditional medicine as anti-parasitic and analgesic. The aim of the present study was to evaluate the effect of four doses of mineral fertilization in two harvest times on the content and composition of the essential oils produced by A. absinthium. The tested doses of mineral fertilization were the following: without fertilization (D0); 50% of the recommended dose (D1); recommended dose (D2); and 150% of the recommended dose (D3). The plants were cultivated in 10 L pots kept in greenhouse. The samples for extracting the essential oils were collected at 60 and 125 days after transplantation (DAT). The essential oils were obtained by hydrodistillation using a Clevenger-type apparatus. Identification and relative percentage of the compounds in the essential oils were performed by GC-MS. The essential oils content varied from 0.04% to 0.41% w/w. The highest essential oil content obtained was 0.41% using the dose D3 at 120 DAT. Myrcene and Z-isocitral were the major constituents of essential oils. According to the results obtained, A. absinthium can be used as a source of myrcene, depending on the dosage of mineral fertilization used and the time of harvest.

The detection of specific DNA sequences by Polymerase Chain Reaction (PCR) has been proven extremely valuable for genetic analysis and diagnosis of a variety of infectious disease pathogens in the veterinary sciences. Genomic techniques applied to veterinary medicine has become fundamental, whether for the detection of pathogens through the use of PCR and its variations or by other techniques that allow the creation and development of recombinant proteins and vaccines for veterinary use. PCR technology has become an indispensable tool in veterinary diagnosis. Other techniques, which play an important prophylactic role for several infectious diseases of veterinary interest, such as recombinant vaccines and sequencing, are important tools in the fight against the most pathogens. In this review, the details of PCR technology are explored, as well as some variations of the technique, such as real-time PCR, as well as other genomic techniques of veterinary interest.

O termo demarketing utilizado há alguns anos como recomendação de redução de produção, problemas de escassez ou baixa demanda, vem ganhando outra conotação ligada a uma visão de produção sustentável e de ações que comunicam um ativismo de marcas. Kotler anunciou um bem-vindo à era do demarketing, considerando o grave problema do excesso de consumo e más políticas de produção. Globalmente, a ONU e diversos governos alinharam-se aos 17 Objetivos de Desenvolvimento Sustentável (ODS’s), bem como o mercado financeiro internacional privilegia os negócios ESG. Mogi das Cruzes, um cinturão verde e econômico da capital paulistana, enfrenta os desafios do êxodo das novas gerações do agronegócio e de como criar ações que agreguem valor aos negócios nos próximos anos. A partir de estudos em andamento, bem como em interações na disciplina de planejamento estratégico na Fatec/Mogi das Cruzes e participações no “Agrofatec Aberta” do curso de Agronegócios, propõe-se aqui a união entre pesquisa e políticas públicas e de empresas que, através da lógica de monetização de ativos ambientais e sociais, tragam engajamento de mídia e parcerias globais, via ações em cadeia de responsabilidade e de uma comunicação integrada que reposicionem o agronegócio. O desafio são as críticas à economia solidária, porém, grandes marcas vêm dando exemplos, projetando ganhos pela mitigação de riscos e monetizações verdes. O presente artigo tem como objetivo introduzir a discussão do demarketing, atualmente tema de estágio pós-doutoral na Eca/USP, como elemento de proposta estratégica para a região de Mogi das Cruzes/SP.
