Abstract Development of insecticides resistance mainly hinge with managements techniques for the control of Jassid, Amrasca biguttutla biguttutla. Five insecticides were applied against field collected and laboratory rared jassid populations during the years of 2017 to 2019 to profile their resistance level against field population of jassid through leaf dip method. Very low resistance level was found in jassid against confidor whereas high level of resistance was observed by pyriproxyfen against other test insecticides. Gradual resistance was observed against diafenthiuron. It is concluded that for the management of Jassid repetition of same insecticide should be avoided. The use of confidor may be reduced to overcome resistance against Jassid.

Abstract Background: In Yemen the epidemiology of COVID19 is uncertain. Yemen received the first batch of AstraZeneca vaccine in April 2021 and the vaccine campaign starts officially on 20 April 2021 with limited utilization. Media play a negative role about AstraZeneca vaccine safety and efficacy.Objectives: to investigate the acceptance of People and health workers in Mukalla city in Hadharmout (at eastern Yemen) toward the COVID-19 vaccine.Methodology: This is a cross-sectional study to collect data from a convenience sample of health workers and other people during the first week of April 2021. Results: A total of 321 persons agree to participate in the study. Only 9% of the participants and 22% of health workers have knowledge about the COVID19 vaccine, only 15% of people and 26% of health workers agree to get the vaccine while 241 participants (75%) hesitated to get the vaccine. The most reasons for vaccine hesitancy were: the vaccine were arrived to Yemen of bad quality (69%), while 48% of hesitated participants said that the vaccine is unsafe, other reasons for unacceptance the vaccine are: regional believes (38%), other countries stop the vaccine (37%) while 16% of refused participants said that the reason is that the virus is subject to mutation so no need to vaccinate. Conclusions: Lack of knowledge about COVID-19 vaccine and high level of vaccine hesitancy were reported, the most frequent reasons for not accepted the vaccine are: bad quality of the vaccine and doubts about vaccine safety.

The common bean is a nutrient-dense food empirically known to have beneficial effects on human health. Many studies have looked at the effects of “pulses” on different health issues, providing general overviews of the importance of each pulse in health studies. This study systematically reviews and provides meta-analyses of the effect of bean extract as a supplement or whole bean on four health issues (cardiovascular diseases, diabetes mellitus, obesity, and cancers) from a dissection of clinical and randomized controlled trials using human subjects. A digital search in PubMed and Google ScholarTM resulted in 340 articles, with only 23 peer-reviewed articles matching our inclusion criteria. Findings indicated that common beans reduced LDL cholesterol by 19 percent, risk of cardiovascular disease (CVD) by 11 percent, and coronary heart disease (CHD) by 22 percent. Besides this, we noted variances in the literature on cancer findings, with some authors stating it reduced the proliferation of some kinds of tumor cells and reduced the growth of polyps, while others did not specifically examine cancers but the predisposing factors alone. However, diabetes studies indicated that the postprandial glucose level at the peak of 60 min for common bean consumers was low (mean difference = −2.01; 95% CI [−4.6, −0.63]), but the difference between the treated and control was not significant, and there was a high level of heterogeneity among studies (I2 = 98%). Only obesity studies indicated a significantly high level of weight gain among control groups (mean difference = 1.62; 95% CI [0.37, 2.86]). There is a need for additional clinical trials using a standardized measure to indicate the real effect of the common bean on health.

Meta-molecules composed of meta-atoms exhibit various electromagnetic phenomena owing to the interaction among the resonance modes of the meta-atoms. In this study, we numerically investigated Fano-like-resonant planar metamaterials composed of meta-molecules at terahertz (THz) frequencies. We present meta-rotamers based only on the difference in the spatial position of their component meta-atoms (C- and Y-shapes) that can be interconverted by rotations and have tunable Fano-like resonance. This is because of the cooperative effects determined by the spatial coupling conditions of the nodes and antinodes of electric-dipole and inductive–capacitive (LC) resonances of the meta-atoms. The findings of this study provide potential options for exploring novel THz devices and for engineering high-level functionalities in metamaterial-based devices.

AbstractIntensive land use (ILU) is a multi-objective optimization process that aims to simultaneously improve the economic, social, and ecological benefits, as well as the carrying capacity of the land, without increasing additional land, and evaluation of the ILU over long time series has a guiding significance for rational land use. To tackle inefficient extraction of information, subjective selection of dominant factor, and lack of prediction in previous evaluation studies, this paper proposes a novel framework for evaluation and analysis of ILU by, first, using Google Earth Engine (GEE) to extract cities’ built-up land information, second, by constructing an index system that links economic, social and ecological aspects to evaluate the ILU degree, third, by applying Geodetector to identify the dominant factor on the ILU, finally, by using the S-curve to predict the degree. Based on the case study data from northern China’s five fast-growing cities (i.e., Beijing, Tianjin, Shijiazhuang, Jinan, Zhengzhou), the findings show that the ILU degree for all cities has increased over the past 30 years, with the highest growth rate between 2000 and 2010. Beijing had the highest degree in 2018, followed by Tianjin, Zhengzhou, Jinan, and Shijiazhuang. In terms of the time dimension, the dominant factor for all cities shifted from the output-value proportion of secondary and tertiary industries in the early stage to the economic density in the late stage. In terms of the space dimension, the dominant factor varied from cities. It is worth noting that economic density was the dominant factor in the two high-level ILU cities, Beijing and Tianjin, indicating that economic strength is the main driver of the ILU. Moreover, cities with high-level ILU at the current stage will grow slowly in the ILU degree from 2020 to 2035, while Zhengzhou and Jinan, whose ILU has been in the midstream recently, will grow the most among the cities.

Objective: To evaluate the effect on the satisfaction of nursing students and the participants of Service-Learning methodology in the development of Health Education workshops. Method: Service-Learning project was designed in four stages: 1) students training in knowledge about Community Nursing and Health Education; 2) development of healthy workshops for its implementation in associations; 3) implementation of the workshops; 4) reflection on Service-Learning impact. An ad hoc questionnaire was developed to assess students’ satisfaction. It was also evaluated the workshops’ participant’s satisfaction.  Results: students reported having a very high level of satisfaction by increasing their scores after improving Service-Learning methodology in the subject. In addition, participants who received health promotion workshops developed by nursing students reported a positive impact on their health. Conclusion: development of Service-Learning methodology associated with health education implies high level of satisfaction in nursing students and a social impact for the community.

The article discusses various approaches to understanding the function of hope in human life. The author attempts to analyze the functional orientation of hope based on its types. The rationale for the study of hope as a multidimensional formation in the context of human life and person's attitude to life is presented. The paper analyzes the conception of hope among Russians, discusses the relationship between different types of hope and valence (positive-negative) of evaluations of different stages of one's life course. It is emphasized that high level of hopelessness combined with negative attitude towards life reduces the psychological security of a person.
