Abstract The sex ratio in the natural population of most Hymenopteran parasitoids is 1 : 1. Females of these parasitoids, however, can regulate the sex of their offspring in response to environmental and biological factors. Under certain circumstances, this may lead to an overproduction of males, which can result in a very negative impact on any control program using these parasitoids. For these reasons, understanding the effect of these factors is very important. In this study, five biological and environmental factors known to affect sex ratio in parasitic Hymenoptera were investigated for Ascogaster quadridentata Wesmael, a parasitoid of Cydia pomonella L. Results showed that food, ambient temperature, and parasitoid age had significant effects on the sex ratio of the offspring of Hymenopteran parasitoids. The percentage of females decreased with lack of food, parasitoid age (when it became 10-days-old or older), and at low (15°C) and high (35°C) temperatures. The effect of host age and density, however, was not significant.

Homosexuality is a phenomenon that has ling existed in human history. It is became the targer of the study to find the contributing factors to the tennets of the Islamic perspective. The desire of homosexuals to change the physical conditions of a male to femare or vice versa is a good convention for sexual purposes or desore to become a mother or father status. The pace and progress of science and technology has helped homesexuals meet their needs, even if the outcome of these treatments may bring much harm to themselves or those around them. High costs of sex change surgeries caused many homosezual stuck to the nature of adultery and leave a negative impact on health. The purpose of this paper is to understand the factor that cause homosexuality: Between law and science. The method used is a qualitative approach and a library. The findidngs of the study showd that the factors that cause the occurrence of homosexuality no only depend on environmental factors such as parents, peers, social and biological factors, but diet and drugs. There is a lack of research on the different schools of taught concerning the change of gender studies, hence it is has become prevalent in the Muslim community. If this is not handled as soon as possible, it not only gives an image that is not healthy within our communities but aslo undermine the development of Islamic civilization.

An automated shower water control system has been implemented to reduce the volume and variability of weak black liquor being sent from the pulp mill to the evaporators. The washing controls attempt to balance the need for consistent and low soda carryover to the bleach plant with consistently high weak black liquor solids being sent to the evaporators. The washer controls were implemented on two bleachable grade hardwood lines (one with oxygen delignification, one without oxygen delignification) and one pine line. Implementation of the control program resulted in an increase in black liquor solids of 0.6 percentage points for the hardwood lines. Significant foam reduction was realized on the pine line since the pine black liquor solids were able to be consistently maintained just below the soap separation point. Low black liquor solids excursions to the evaporators were eliminated. Bleach plant carryover was stabilized and no negative impact on chemical consumption was noticed when controlling weak black liquor solids to recovery.

Education Concept

Abstract Paradoxically, the more educated and wealthier the society is, the greater the negative impact on the environment, because the consumption needs are higher, which leads to an increase in the pollution of the environmental factors. This leads us to the conclusion that, in order to achieve sustainable development, education of the population is not sufficient. The link between sustainable development and education is very complex, and the challenge faced by mankind is to educate the population to become a factor of change.

Steady Increase

Modern crop cultivation technologies have reached the limits of “saturation” both in the ecological (environmental pollution, suppression of the mechanisms of its self-regulation), energy (exponential growth of irreplaceable energy costs for each additional unit of production), and in production. In this regard, environmental factors (air drought, frosts, active temperatures, etc.), which cannot be optimized, are becoming increasingly important in ensuring a steady increase in the yield of cultivated plant forms. In recent decades, more and more attention has been paid to technogenic and biological systems of agriculture, based on the ecologization and biologization of the intensification processes of adaptive crop production. Such approaches are the precision agriculture system (PA) and QTL analysis. Using these approaches allows not only to ensure a steady increase in productivity due to the combined use of the advantages of precision farming and molecular genetic assessment, including the creation of new forms and varieties that are responsive to РА agricultural practices, but also to level the negative impact of abiotic and biotic environmental factors that limit the size and quality of the crop as well as plant productivity. It is shown that the strategy of adaptive intensification of crop production through the use of the TK system and QTL analysis approaches is not alternative to existing farming systems, however, it focuses modern agriculture on the growth of knowledge-intensive agricultural production as a whole. An analysis of the causes under consideration, the current unfavorable trends in modern crop production and agriculture, clearly shows their scale and long-term nature, and therefore the inevitability of the search for new priorities for intensification of crop production and agriculture, providing a qualitatively new stage of their development in the interests of man.

The Impact

The impact of globalization has penetrated throughout the civilization of the nations of the world, running so fast. Especially very influential on changes in various lines of life. Related to this is the issue of increasing narcotics abuse and narcotics illicit trafficking which has created conditions that have hindered the development process and weakened civilization. Eradication of narcotics distribution is a national problem, because it has a negative impact that can damage and threaten the lives of the people, nation and state and can hamper the national development process. The rise of narcotics abuse does not only occur in big cities, but has reached small cities in all ten regions of the Republic of Indonesia, including East Aceh Regency. The increasingly diverse lifestyle of the people due to the influence of globalization also contributes to the increasing circulation of narcotics in East Aceh District. This certainly must receive serious attention, because if we look at what is happening in East Aceh District and several other regions in Indonesia, the crime of narcotics distribution from time to time always increases which in the end is increasingly unsettling the community, so before these things increase In East Aceh District, an effective solution must be found to eradicate it. Factors that cause a person to commit a narcotics crime in East Aceh Regency are due to economic factors where a person needs money to live and the difficulty of getting work, family environmental factors, social environmental factors and availability / lack of supervision factors. Efforts in tackling narcotics circulation in East Aceh district involve many parties, including: firstly, pre-emptive efforts by providing counseling in the community and schools about narcotics carried out by the police in tackling narcotics crime in East Aceh District. Second, preventive measures (prevention) by conducting raids and patrols routinely, providing oversight of the association and positive activities carried out by the police, prosecutors, religious leaders, community leaders and youth organizations. The third repressive effort (action) which aims to provide a deterrent effect on the perpetrators of drug trafficking crimes involving all law enforcement officials ranging from the Police, Attorney and District Courts and Detention Houses.Keywords: Crimonology, Narcotics Circulation.

FACTORS THAT AFFECTING THE TOXICITY OF POLLUTANTS TO AQUATIC ORGANISMS. There are a large number of pollutants in aquatic environment with various characteristics and factors that can modify and affect the toxicity of pollutants in this environment. The major factors affecting pollutant toxicity include physicochemical properties of pollutants, mode of exposure, time, environmental factors, and biological factors. Moreover, organisms in an aquatic ecosystem are seldom exposed to only single pollutant, and most cases the stress of pollution on aquatic ecosystems is related to the interaction and combined effects of many chemicals. The combined effects may be synergistic or antagonistic, depending on the pollutants and the physiological condition of the organism involved.

Ultimate Outcome

This chapter provides an overview of anxiety in general, and child anxiety in particular. A child who is anxious is typically going to overestimate the likelihood of negative events and to downplay the likelihood of positive ones. What is the ultimate outcome of these predictable patterns of thinking? If negative events seem highly probable, while positive events seem less likely, it is not surprising that anxious children tend to veer away from perceived risks and to move toward a more cautious course of action. The chapter then addresses some common questions asked by parents of children with anxiety. Multiple things can contribute to a child’s anxiety level, including internal and biological factors as well as external and environmental factors. Anxiety can also look very different in different children. It is useful to think about a child’s functioning in four separate domains: body, thoughts, behavior, and feelings. Anxiety can impact each domain in various ways.

The Impact

Recently, green innovation efficiency, which considers innovation and environmental factors, is gradually becoming important for the sustainable development of Chinese heavy polluting industries because of the increasing strictness in China’s environmental regulations. Previous studies ignore the impact of external environmental factors on the efficiency of green industry innovation and fail to explain the complex relationship between environmental and technical efficiency fully. Therefore, a non-radial directional distance function-data envelopment analysis (DDF-DEA) three-stage green innovation efficiency evaluation model was constructed to measure the green innovation efficiency of China’s heavy polluting industries objectively and explore the impact mechanism of external factors. Then, the aforementioned model was used to conduct an empirical test on China’s heavy polluting industries. Results indicate that the green innovation efficiency of heavy polluting industries is generally low in China, and the entire industry is in the transitional stage of “effective innovation but not green.” The uncertainty of the effect of the environmental regulation policy, the over-reliance on external technologies, and the scale diseconomies of industries, which are the key factors in improving the green innovation efficiency of China’s heavy polluting industries, have a significant negative impact on green innovation efficiency. The conclusions of this study can provide a useful reference for China and other emerging markets to formulate reasonable environmental regulations and green transition of heavy polluting industries.
