Influence of Interlayer Soil on the Water Infiltration Characteristics of Heavy Saline–Alkali Soil in Southern Xinjiang
Authors: Liu Hongbo , Wu Bin , Zhang Jianghui , Bai Yungang , Li Xianwen , Zhang Bo
Published: July 2023

Interlayer soil is common in southern Xinjiang, because interlayer can reduce the infiltration rate of soil water. To simulate the interlayer soil in heavy saline–alkali cotton fields, this paper adopted a vertical one-dimensional infiltration test. T1 (315 mm), T2 (270 mm), and T3 (225 mm) and different interlayer positions (T5, 315 mm) and thicknesses of the interlayer (T6, 315 mm) with the same irrigation volume, as well as one perforation and sand filling treatment (T4, 315 mm), were set. The influence of different irrigation amounts, locations, and thicknesses of the interlayer and sand injection on water infiltration was analyzed. The analysis results showed that with the increase in irrigation amount, the water infiltration rate and the migration distance of the wet front increased, but did not penetrate to the bottom soil (90 cm). Under the same irrigation volume, the increase in interlayer thickness (T6) compared with the increase in interlayer position (T5), the change in soil moisture content in the upper and lower layers of the interlayer was greater, and the advance time of wetting front migration and cumulative infiltration were slightly higher. After tunneling and sand filling (T4), the infiltration rate of water was increased, the migration time of the wet front was reduced, and the profile water content of each soil layer was improved. The Kostiakov model could better simulate the water infiltration characteristics of interlayer soil with different profile configurations in heavily saline–alkali land. The results showed that in all of the treatments, only the wet front of the soil moisture reached 100 cm in the T4 treatment, and the maximum was only 87.8 cm in the other treatments, indicating that too little irrigation water or the upward movement and thickening of the interlayer were not conducive to water infiltration. For the interlayer soil area in the heavy saline–alkali land in southern Xinjiang, the appropriate irrigation water should be more than 315 mm. The treatment of drilling first and then filling sand can be used as a simple but effective measure to increase the water infiltration rate of the interlayer soil, and can thus be applied to the layered soil structure in the interlayer position of 60–80 cm.
Natural Drugs: A New Direction for the Prevention and Treatment of Diabetes
Authors: Wu Peishan , Wang Xiaolei
Published: July 2023

Insulin resistance, as a common pathological process of many metabolic diseases, including diabetes and obesity, has attracted much attention due to its relevant influencing factors. To date, studies have mainly focused on the shared mechanisms between mitochondrial stress and insulin resistance, and they are now being pursued as a very attractive therapeutic target due to their extensive involvement in many human clinical settings. In view of the complex pathogenesis of diabetes, natural drugs have become new players in diabetes prevention and treatment because of their wide targets and few side effects. In particular, plant phenolics have received attention because of their close relationship with oxidative stress. In this review, we briefly review the mechanisms by which mitochondrial stress leads to insulin resistance. Moreover, we list some cytokines and genes that have recently been found to play roles in mitochondrial stress and insulin resistance. Furthermore, we describe several natural drugs that are currently widely used and give a brief overview of their therapeutic mechanisms. Finally, we suggest possible ideas for future research related to the unique role that natural drugs play in the treatment of insulin resistance through the above targets.

Improving Extension Programs: Putting Public Value Stories and Statements to Work
Authors: Franz Nancy
Published: July 2023

Extension has begun to embrace the public value movement that originated in public administration circles. The motivation appears to be driven by external accountability rather than internal interest in improving programming and results. The development of public value statements and stories can be used throughout the program cycle and for other program and professional tasks to help address internal and external cries for the articulation of public value. Extension workers should use public value statements and stories in their work on a daily basis in a variety of ways to enhance their effectiveness and the transformative impact of their programs.
불가피성의 윤리와 불가분성의 윤리 - 인간복제의 측면에서 갈등을 중재하기 위한 시도
Authors: KOO Mi-Jung , YANG Jae-Sub
Published: July 2023

복제양 돌리의 출현은 인류 역사에서 하나의 분수령이 된다. ‘바이오테크’ 시대로 접어든 인류는 생명에 대해 전권을 휘두르는 무한한 능력을 소유하게 되었다. 그러나 운전도 할 줄 모르는 어린아이에게 차 열쇠를 맡길 수는 없는 노릇이다. 돌리 출현 직후, 미국에서 인간 복제 연구에 대한 모라토리엄 선언이 나온 배경에는 그러한 우려가 깔려있었을 것이다.
우리나라의 경우, 생명공학기술은 세계 우위를 점하면서도, 생명윤리의식은 후진국 수준을 면치 못하고 있다. 윤리의식의 부재는 기술문명의 파국을 불러올 것이므로, 지금이야말로 ‘인간이후 시대’를 대비하여 올바른 인간관의 정립이 시급하다.
인간복제를 찬성하는 사람들은 어차피 언제 어디선가는 반드시 인간복제가 이루어질 것이라고 말한다. 그들은 여러 가지 이유를 들어 인간복제가 ‘불가피하다’고 강변한다. 이른바 ‘불가피성의 윤리’는 그것에 반대하는 모든 논변을 비웃으면서 사람들 사이에 무기력감과 체념을 유포시킨다. 그러나 우리가 이와 같은 불가피성의 윤리에 사로잡혀 소수의 과학엘리트들이 이끄는 대로 무분별하게 끌려간다면, 인간이 기계와 다를 바가 무엇인가? 현시점에서 우리에게는 숙명론적 혹은 결정론적 불가피성을 넘어서는 일이 우선시된다.
불가피성의 윤리가 과학기술적 정언명령에서 나온다면, ‘불가분성의 윤리’는 직관주의적 각성에서 나온다고 할 수 있다. 불가분성의 윤리가 지시하는 대로 만물의 상호연관성과 상호의존성을 깨닫고 나면, 카우보이식으로 밀어붙이는 영웅주의적 과학행위가 아니라 후세대와 지구생명에 더욱 민감한 책임적 과학행위에 헌신할 수 있다. 여기서 직관주의 윤리가 지속적인 사회적 구속력을 가지려면, 예컨대 현재 유럽 국가들에서 시행되고 있는 ‘합의회의’나 ‘과학상점’등의 시민참여기구가 제도화될 필요가 있다.
새로운 시대로 들어갈 때마다 우리는 인간이란 무엇이며 어떤 종류의 인간성을 키워야 하고 어떤 미래를 열어갈 것인지 끊임없이 고민해야 한다. 어쩌면 21세기에 요청되는 인간개념은 ‘호모 에콜로지쿠스’인지도 모른다. 호모 에콜로지쿠스는 생태학의 법칙에 따라 현재의 위기를 창조적으로 극복하기 위한 하나의 원형(prototype)적 개념이다. 호모 에콜로지쿠스는 기계론적 인간관에 기반한 결정론적 불가피성에 사로잡히지 않고, 오히려 만물의 불가분성을 존중하여 생명윤리에 헌신한다. 만약 우리가 어떠한 윤리적 선택을 함에 있어서 인간 이외의 다른 피조물과 후세대와 생태계 전체의 안녕을 준거로 삼을 수 있다면, 다시 말해, 불가분성의 윤리가 우리의 사고방식과 생활양식 전반을 이끄는 하나의 원천이자 방향이 될 수 있다면, 불가피성의 윤리는 불가분성의 윤리와 화해할 수도 있을 것이다. 왜냐하면 그 때 비로소 우리는 “내가 이것을 행하는 것이 불가피한 까닭은 이것이 만물의 불가분성을 해치지 않고 오히려 증진하기 때문이다”라고 말할 것이기 때문이다.
Factors that Influence Clinical Nurses’ Moral Courage*

Published: July 2023

Although moral courage can play an important role in resolving some of the ethical dilemmas faced by clinical nurses, the concept of moral courage is in need of greater clarification. This study investigates some of the factors that influence moral courage, including moral sensitivity, ethical decision-making confidence, and ethical environment. A total of 148 nurses agreed to participate in an online survey for this study. The collected data were analyzed with Pearson’s correlation coefficient and multiple regression using the IBM SPSS 24 program. The analysis indicates that moral courage has a significant correlation with moral sensitivity (r=.55, p<.001), ethical decision-making confidence (r=.65, p<.001), and ethical environment (r=.66, p<.001). Ethical decision-making confidence and ethical environment were derived as factors that affect moral courage, and the explanatory power of these variables is 52.0% (F=20.94, p<.001). These findings justify the creation of ethical clinical environments in which nurses’ ethical decision-making confidence can be expressed as actual behavior. In addition, it is argued that ethical regulations and guidelines within clinical settings should be clarified in order to establish support systems that protect the well-being of patients and reflect the true value of professional nurses.
The ferroelectric orthorhombic phase formation of Hf0.5Zr0.5O2 thin films on (−201) β-Ga2O3 substrate by atomic layer deposition
Authors: Naito K. , Yamaguchi K. , Yoshimura T. , Fujimura N.
Published: July 2023

The orthorhombic (O) phase formation process of Hf0.5Zr0.5O2 (HZO) thin films on Ga2O3 substrate is demonstrated. As deposited HZO thin film has the O and tetragonal (T) phases together with an amorphous phase and post-metallization annealing suppresses the crystallization into the T phase and promotes the O phase compared to annealing without a top electrode. Positive-up-negative-down measurement reveals that remanent polarization for the downwards (accumulation side) only originates from the ferroelectricity in HZO films on Ga2O3 substrate. Using normal capacitance–voltage (C–V) measurements, a clear capacitance change from accumulation to depletion was observed. However, the C–V results also show clockwise hysteresis by charge injection from the semiconductor. High-speed C–V measurements at a voltage sweep frequency above 3 Hz show counterclockwise hysteresis, and hysteresis width saturates as the applied voltage increases. Based on these results, HZO thin films with O phase on Ga2O3 substrates have ferroelectricity.

Published: July 2023

The study may enhance your mental health by keeping a healthy work-life balance by establishing clear priorities, setting realistic plans and routines, and learning time management skills. To achieve work-life harmony, you must do more than simply pare down your to-do list. The benefits of a well-balanced schedule are not limited to people who have a lot of work to do; in fact, the better mental health that comes from a work-life balance may lead to improved productivity.If you want to keep a good work-life balance, you need to know what that looks like for you, given your unique set of circumstances. Many individuals underestimate the significance of work-life balance because they have erroneous or no perceptions of what it may or should look like.WORK-LIFE BALANCEWork-life balance seems to be the capacity of a person to meet their family and work obligations, as well as other commitments and activities undertaken outside of work hours and during their leisure time. In order to maintain a healthy work-life balance, you don't have to divide time equally between work and personal pursuits. An individual's capacity to retain happiness in both their personal and professional lives while also managing their time and efforts efficiently is known as ‘work-life balance.’
GENTRIFICAÇÃO SUBURBANA, DISPLACEMENT E IDENTIDADE TERRITORIAL : O CASO DE ALMADA
Authors: Cortez Pedro
Published: July 2023

Este artigo explora as expressões contemporâneas da gentrificação na metrópole de Lisboa e, especificamente, a extensão do fenómeno ao concelho de Almada, a partir da questão do displacement. O trabalho de investigação foi realizado entre 2019 e 2022, e baseou-se em observação participante em espaços recentemente requalificados dos territórios de Cacilhas e Cova da Piedade, bem como em entrevistas semidiretivas a residentes e ex-residentes que passaram há pouco tempo por situações de displacement, traduzidas em desalojamentos residenciais e numa diminuição da sua identificação com o lugar. Entre os principais resultados, verificou-se que as pessoas que conseguem permanecer no bairro fazem-no sujeitando-se a piores condições de habitação. Para estes residentes, diminuiu o sentimento de pertença ao lugar, com uma perda de espaços de encontro e consumo em resultado da requalificação dos espaços públicos e da reestruturação do tecido comercial.

The vehicle simulated is a six-passenger side-by-side intermeshing rotor helicopter with hybrid propulsion for air taxi operations, also known as urban air mobility applications. This concept vehicle is intended to focus and guide NASA research activities in support of aircraft development for emerging aviation markets, in particular vertical take-off and landing air taxi operations.
Ni recatadas ni sumisas
Authors: Fuller Osores Norma
Published: July 2023

La presente investigación indaga si los recientes movimientos de critica a las masculinidades hegemónicas han influido en las conductas y nociones de masculinidad de las nuevas generaciones.  Se realizaron entrevistas a una muestra de 40 jóvenes universitarios de las universidades públicas y privadas más prestigiosas de la ciudad de Lima, Perú. Elegimos al medio universitario porque ha sido escenarios de la emergencia de un pujante movimiento feminista. Nos centramos en las relaciones con las mujeres más significativas en la vida de los varones: madres, hermanas, amigas y parejas. Los resultados de la investigación revelan cambios y permanencias. Las mujeres vistas por los jóvenes son independientes y han conquistado el espacio público a través de los estudios y el trabajo. No pocas de ellas critican el modelo de masculinidad tradicional. En cuanto a las permanencias: las madres siguen asociadas al cuidado del hogar y persisten nociones tradicionales sobre la feminidad (fragilidad, necesidad de protección) que legitiman formas de control. La identificación de masculinidad con iniciativa sexual, control de las mujeres y autoridad siguen vigentes. Una proporción de los jóvenes perciben estas ambigüedades y se muestra abierta al cambio. Una minoría se reafirma en nociones aprendidas y rechaza los movimientos que los confrontan.
Inteligencia artificial, autoconciencia y derechos humanos de los sujetos artificiales
Authors: Suárez-Muñóz Flavio
Published: July 2023

La inteligencia artificial como tecnología que imita el comportamiento humano, ha tenido grandes avances gracias al desarrollo tecnológico que sirve de plataforma para el procesamiento de grandes cantidades de información, esto permite que la tecnología conozca a las personas de manera detallada y con ello reproducir emociones y sentimientos de manera artificial. De modo que esta tecnología ha superado a las personas en capacidades como las matemáticas, la predicción y la toma de decisiones, no obstante, la lingüística representa una limitante para esta tecnología, ya que la semántica que es la que da sentido a las palabras, aún no ha sido superada del todo por las máquinas. Por otro lado, la autoconciencia es intrínseca de las personas, esta está impresa de manera biológica en el cerebro para poder ser conscientes del entorno, esta se potencia con la interacción con el entorno, pero a la inteligencia artificial le falta esta red biológica que detona la conciencia interna, por ello, no puede ser autoconsciente, esto nos lleva a que los intentos por reconocerles derechos humanos a estas tecnologías, no prosperen, al menos no en el corto plazo.

Impact of reactive oxygen species on the progression of human diseases by damaging biomolecules
Authors: Pathak Vinay , Kant Ruchi , Kumar Navneet
Published: July 2023

Reactive oxygen species (ROS) are the molecules which have oxygen an atom in its highly reactive form. ROS are formed as a byproduct of normal metabolism and are removed by the antioxidants and enzymes present in the system. But, uncontrolled formation of ROS due to various factors like diseases or stress causes damage to the biomolecules. This oxidation of biomolecules by ROS might help in the progression of human diseases. Understanding the mechanism of development of different human diseases caused due to ROS will help to control the severity of the diseases. Also, on the basis of types of ROS involved, an antioxidant supplement can be selected to mitigate the effect of ROS and ultimately lower the severity of the disease. In this review article, we have tried to summarize the literature available from different sources on ROS formation, biomolecule oxidation and their impact on the progression of various diseases in humans.
Effects of silver nanoparticles on multiple drug-resistant strains of Staphylococcus aureus from periodontal infection: An alternative approach for antimicrobial therapy
Authors: Noori Mahal Shaimaa , Mohammed Turki Ahmed , Hazeim Abdulkareem Elham
Published: July 2023

Introduction and Aim: Most cases of periodontitis are associated with microorganisms. The Gram positive bacteria Staphylococcus aureus is considered as one of the important organisms associated with periodontal infections. This study investigated the effect of silver nanoparticles as well as the antiseptic agent chlorhexidine on multi-drug resistant S. aureus isolated from periodontal infections.
 
Materials and Methods: In this study, with help from dentists, 266 clinical samples were collected from dental patients who had periodontal infection. S. aureus isolated from samples was tested for their antibiotic susceptibility profiles. Silver nanoparticles and chlorhexidine were evaluated for their antibacterial activity against these S. aureus isolates.
 
Results: S. aureus strains isolated from periodontal infection patients in this study were found to be multidrug resistant. AgNPs obtained using E. coli showed high inhibition of S. aureus growth when used in different concentrations (5, 10, 15, 20, 25mM). Chlorhexidine also exhibited antibacterial activity against S. aureus. Combination of AgNPs with penicillin and ciprofloxacin had an increasing significant effect on the sensitivity of S. aureus. Similarly, chlorhexidine in combination with penicillin and ciprofloxacin also showed an inhibitory effect on the growth of S. aureus.
 
Conclusion: AgNPs and chlorhexidine combined with antibiotics used in treatment of S. aureus isolated from periodontal disease showed a good antibacterial effect which suggests its use as an antibacterial agent against periodontitis associated bacteria.
Towards the systematic reconnaissance of seismic signals from glaciers and ice sheets – Part A: Event detection for cryoseismology
Authors: Latto Rebecca B. , Turner Ross J. , Reading Anya M. , Winberry J. Paul
Published: July 2023

Abstract. Cryoseismology is a powerful toolset for progressing the understanding of the structure and dynamics of glaciers and ice sheets. It can enable the detection of hidden processes such as brittle fracture, basal sliding, transient hydrological processes, and calving. Due to the diversity and often low signal-to-noise levels of glacier processes, the automated detection of seismic events caused by such processes can pose a challenge. We present a novel approach for the automated detection of events in glacier environments, the multi-STA/LTA algorithm, with a focus on capturing the many signal types recorded on ice sheet margins. This develops the use of approaches that use the ratio between short and long time averages (sta,lta) of signal amplitude as the means of event detection. Implemented in the open source and widely used ObsPy python package, the algorithm constructs a hybrid characteristic function from a set of sta, lta pairs. We apply the multi-STA/LTA algorithm to data from a seismic array deployed on the Whillans Ice Stream (WIS) in West Antarctica (austral summer 2010–2011), to form an event catalogue. The new algorithm compares favorably with standard approaches, yielding a diversity of seismic events, including all previously identified stick-slip events (Pratt et al., 2014), teleseisms, and other noise-type signals. We investigate a partial association of seismicity with the tidal cycle, and a slight association with ice temperature changes of the Antarctic summer. The new algorithm and workflow has the potential to yield systematic catalogues for further cryoseismology studies: conventional glacier seismology, and those tailored to pattern recognition by machine learning.
Modelling the terrestrial nitrogen and phosphorus cycle in the UVic ESCM
Authors: De Sisto Makcim L. , MacDougall Andrew H. , Mengis Nadine , Antoniello Sophia
Published: July 2023

Abstract. Nitrogen (N) and phosphorus (P) biogeochemical dynamics are crucial for the regulation of the terrestrial carbon cycle. In Earth
system models (ESMs) the implementation of nutrient limitations has been shown to improve the carbon cycle feedback representation and, hence,
the fidelity of the response of land to simulated atmospheric CO2 rise. Here we aimed to implement a terrestrial N and
P cycle in an Earth system model of intermediate complexity to improve projections of future CO2 fertilization feedbacks. The
N cycle is an improved version of the Wania et al. (2012) N module, with enforcement of N mass conservation and the merger
with a deep land-surface and wetland module that allows for the estimation of N2O and NO fluxes. The N cycle module
estimates fluxes from three organic (litter, soil organic matter and vegetation) and two inorganic (NH4+ and NO3-) pools and accounts for inputs from biological N fixation and N deposition. The P
cycle module contains the same organic pools with one inorganic P pool; it estimates influx of P from rock weathering and losses from
leaching and occlusion. Two historical simulations are carried out for the different nutrient limitation setups of the model: carbon and nitrogen
(CN), as well as carbon, nitrogen and phosphorus (CNP), with a baseline carbon-only simulation. The improved N cycle module now
conserves mass, and the added fluxes (NO and N2O), along with the N and P pools, are within the range of other studies
and literature. For the years 2001–2015 the nutrient limitation resulted in a reduction of gross primary productivity (GPP) from the carbon-only value of 143 to
130 Pg C yr−1 in the CN version and 127 Pg C yr−1 in the CNP version. This implies that the model
efficiently represents a nutrient limitation over the CO2 fertilization effect. CNP simulation resulted in a reduction of 11 %
of the mean GPP and a reduction of 23 % of the vegetation biomass compared to the baseline C simulation. These results are in better
agreement with observations, particularly in tropical regions where P limitation is known to be important. In summary, the implementation of
the N and P cycle has successfully enforced a nutrient limitation in the terrestrial system, which has now reduced the primary
productivity and the capacity of land to take up atmospheric carbon, better matching observations.

Published: July 2023

Crosslinking methods have been used to improve the properties of soy protein-based films for various applications, such as meat packaging. Some of the crosslinking methods that have been reported in the literature include boiling soy milk, baking soy protein isolates, adding canola and sorghum proteins, incorporating Plantago major seed mucilage and Anethum graveolens essential oil, adding pine needle extract (PNE), incorporating montmorillonite and citric acid, using xylose as a crosslinker, and crosslinking with glutaraldehyde. The incorporation of additives such as canola and sorghum proteins, Plantago major seed mucilage and Anethum graveolens essential oil, and pine needle extract (PNE) has also been reported to improve the properties of soy protein-based films. In conclusion, soy protein-based films have excellent film-forming properties and many functional characteristics, making them a promising material for food packaging applications. However, their poor moisture barrier properties must be improved to make them more suitable for food packaging applications. Crosslinking methods have been used to improve the properties of soy protein-based films for various applications, such as meat packaging. The incorporation of additives such as canola and sorghum proteins, Plantago major seed mucilage and Anethum graveolens essential oil, and pine needle extract (PNE) has also been reported to improve the properties of soy protein-based films.

La evolución reciente de las exportaciones españolas de servicios no turísticos
Authors: Martín Machuca César , García Coral
Published: July 2023

Motivación

El elevado dinamismo de las exportaciones de servicios no turísticos tras la pandemia ha contribuido significativamente a la recuperación de la economía española, por lo que resulta de interés analizar su evolución reciente.

Ideas principales

•El crecimiento acumulado por las exportaciones reales de servicios no turísticos entre 2020 y 2022 ascendió prácticamente al 50 %, de manera que, en 2022, estas se situaron cerca de un 20 % por encima del nivel de 2019, brecha sensiblemente superior a la de otros componentes de la demanda final.

•La recuperación de las exportaciones de servicios no turísticos tras la pandemia ha intensificado el crecimiento sostenido de esta partida observado en las últimas décadas y se ha apoyado, principalmente, en los servicios empresariales, de transporte y tecnológicos, dirigidos, sobre todo, al área del euro y a América del Norte.

•La capacidad competitiva de las grandes empresas exportadoras en España, que suelen pertenecer a grupos empresariales, podría explicar, al menos en parte, el elevado dinamismo de las exportaciones de servicios no turísticos tras la pandemia.

In this investigation, we report the synthesis of Goethite-NFs/CNTs nanocomposites using hydrothermal method at optimized growth condition. These nanostructured products have been characterized in order to identify their physico-chemical properties by different techniques, such as X-Ray Diffraction (XRD), Raman Spectroscopy, High Resolution Scanning Electron Microscopy (FESEM), Thermal analysis (TGA/DTA) and UV- Vis Spectroscopy. The obtained Goethite nanofibers (NFs) have shown structured triangular base nanofibers with diameter in the range [181 - 363 nm]. Using nested and twisted CNTs (MWNTs type) but fairly homogeneous in diameter around 48 nm, the formation of an assembly of two forms (MWNTs and iron oxide Nanofibers) in nanocomposite configuration confirms the significant improvement of their physico-chemical properties, like the increase in their electrical conductivity proven by their obtained gap energy Eg from 3.12 to 2.50 eV. Consequently, the reached results prove clearly that this kind of iron oxide-NFs/MWNTs based nanocomposites can be excellent candidate as electroactive nanomaterials for energy storage application.
Recent Work on Skepticism in Epistemology
Authors: Ranalli Chris
Published: July 2023

This paper critically surveys 20 years of recent work on radical skepticism. It focuses on three key issues. First, it starts by exploring how philosophers have recently challenged our understanding of radical skeptical arguments. It then unpacks and critically evaluates some influential reactions to radical skepticism: structuralism, knowledge-first epistemology, epistemological disjunctivism, and hinge epistemology. Third, it explores some novel developments of pragmatism, like pragmatic skepticism, gauges its anti-skeptical import, and reflects on the ways in which radical skeptical epistemology and ethics might meet.
Influence of autumn leaf plucking on the growth and yield parameters of mulberry under temperate clmatic conditions
Authors: Mir M. , Kour R. , Isa Md. , Rashid Haroon , Khan M.
Published: July 2023

In the valley of Kashmir, with temperate climatic conditions, the complete leaf fall in Mulberry occurs during November and the plants enter into dormancy. The sprouting of winter buds starts during the last week of March. Growth of Mulberry after the dormant period depends upon the food material accumulated in the stems/stumps during the previous autumn. Mulberry plants when subjected to leaf plucking during autumn exhibited a marked decline in growth and yield in following spring. When 100% leaf plucking was resorted to in autumn, sprouting of winter buds during the subsequent spring decreased by 14.29% and leaf yield per plant got reduced by 30.66% as compared to the plantation where no leaf plucking was done. The decline in yield and growth parameters may be attributed due to insufficient accumulation of food reserves in the plant by virtue of leaf plucking during autumn.

What about the emotional labor of university teachers in teaching? A survey from a Chinese university
Authors: Jiuhua ZHENG , LIU Na
Published: July 2023

Emotional labor is an important factor that affects the teaching effectiveness of teachers, and university teachers are no exception. In order to understand the current status of emotional labor among university teachers, this paper investigated the emotional labor of 253 university teachers from China. The results showed that university teachers have a high perception of emotional display rules, and engage in high levels of emotional labor behavior. They employ more deep acting and naturally felt emotion strategies in emotional labor, and age differences were found in surface acting, which decreases with age. Finally, this paper proposes suggestions for improving the impact of emotional labor at both the individual and organizational levels. University teachers need to continuously improve their own emotional management abilities and intrinsic work motivation, while universities need to create a good educational ecological environment and provide social support for university teachers.
