Abstract

The research aims to study this phenomenon for one of the vital streets of the Baghdad city center to verify the psychological, aesthetic and health dimensions, visual and environmental pollution as cognitive outputs of the phenomenon of the spread of health services and transform the streets from vital whole streets to health centers with a single use. Primary research data obtained using a questionnaire as an instrument consisting of 25 questions addressed to 20 people who have been determined according to the expertise and objects of the study. The object of research is the use of land and buildings on Al-Kindi Street in Al-Harithiya, Baghdad City. It popped up in Iraqi cities emerged because of the deterioration of the security situation, the phenomenon of changing land uses from residential to commercial, and some of them have turned into health uses in the form of individual buildings and complexes in city centers, modern urban centers, and commercial streets. Which caused distortions in the urban scene because of the lack of controls regulating these uses and contributed to the mixing of patients with citizens using these places. A difference found in the evaluation of cognitive outputs of the phenomenon of changing street uses, where the psychological dimensions got 85 percent, the health dimensions 90 percent, and the aesthetic dimensions got 40 percent. These results illustrate the dangerous dimensions of this phenomenon on the behavior and health of citizens and society.

Abstract

As our fossil sources of electricity reduce consistently, then looking for alternative electricity solutions turns into crucial. Solar cells often made from expensive materials, which is why much research focused on finding cheaper materials to reduce the overall cost of solar energy. Another way to overcome this problem is to use a solar concentrator - a cheaper light-absorbing material that covers a large area, which absorbs, directs, and focuses the light to a smaller area that contains actual solar cells. The interest in exploiting solar electricity for photovoltaic energy has grown dramatically in the latest years, furthermore essential improvements inside the solar cells? efficiency with luminescent up or down converters have currently anticipated theoretically. While solar cells are still expensive, fewer of them needed to produce a certain amount of electricity because they receive more sunlight. This paper gives, in short, evaluate the usage of luminescent solar concentrator (LSC) as opportunity electricity has low fees and comfortable as compared with photovoltaic solar panels, reviewing extra benefits in actual existence applications primarily in high structures home windows and displays of electronic devices.

Abstract

Viral infections contribute 15?20 percent of all human cancers as a cause. Oncogenic virus infection may spur various stages of carcinogenesis. For several forms for HPV, about 15 associated with cancer. Following successful test techniques, cervical cancer remains a significant public health issue. Prevalence and mortality of per geographic area of cervical cancer were vastly different. The fourth most common cause of death from cancer among women is cervical cancer (CC). Human papillomavirus (HPV) infection in the cervix is the most significant risk factor for forming cervical cancer. Inflammation is a host-driven defensive technique that works rapidly to stimulate the innate immune response against pathogens such as viral infections. Inflammation is advantageous if it is brief and well-controlled; however, it can cause adverse effects if the inflammation is prolonged or is chronic in duration. HPV proteins are involved in the production of chronic inflammation, both directly and indirectly. Also, the age-specific prevalence of HPV differs significantly. Two peaks of HPV positive in younger and older people have seen in various populations. A variety of research has performed worldwide on the epidemiology of HPV infection and oncogenic properties due to specific HPV genotypes. Nevertheless, there are still several countries where population-dependent incidences have not yet identified. Additionally, the methods of screening for cervical cancer differ among countries.

Abstract

The main stages of the primary materials are that feed the furnaces to form the mineral compounds of cement, which are the stage of drying the materials from water at a temperature of 100 degree Celsius and moving to the crystallization area at a temperature of 550 degree Celsius. Thus, the free lime begins to break down the calcium carbonate by interacting with silica and clay compounds to form (C2S) at a temperature 900 degree Celsius. In the transition region at a temperature of 1260 degree Celsius begins the formation of liquid compounds (C3A, C4AF), where the formation of a compound (C2S) continues and begins to form a compound (C3S). When the temperature rises at 1450 degree Celsius, the formation of the vehicles is complete, and this depends on the quality of the blended raw materials that affect the life of the firing blocks and the fuel consumption. As for the silica coefficient, it has a major role in determining the clinker quality, as the best silica coefficient (2.7) was obtained, as well as the best coefficient of alumina (1.38), as well as obtaining the best lime saturation coefficient (0.96) and the percentage of magnesium oxide not exceeding 5 percent, thus stabilizing the ratio Magnesium oxide to form the best burning plants (108). The difference in the concentration of substances leads to an incomplete chemical reaction and this affects the size of the resulting crystals.

Abstract

Energy currently has a crucial role in human life. So far, the primary buffer of energy needs still relies on petroleum. Meanwhile, petroleum is inevitably increasingly scarce and expensive. With the state of the depletion of fossil energy sources, in today's world, there is a shift from the use of non-renewable energy sources to renewable energy sources. Of the many renewable energy sources, the use of energy through solar cells is the most potent alternative to applied in Indonesia. Solar energy is one of the energies currently actively developed by the Indonesian government because as a tropical country, Indonesia has considerable solar energy potential. Solar energy is extraordinary because it is not a pollutant, cannot use up, can trust and does not buy. There are many ways to harness energy from the sun. The electricity we can use today is electricity produced from the process of burning fossil fuels such as coal, oil or natural gas. The combustion results will produce carbon dioxide gas which can damage or adversely affect the environment. Solar electricity can provide electricity continuously because its energy source is a renewable energy source and is also a clean and environmentally friendly energy, to reduce greenhouse gas emissions. Besides, solar electricity can provide electricity quickly and does not require individual costs for maintenance and can provide electricity needs in rural areas, isolated areas, and islands that not electrified by the government.

Abstract

Determination of water quality status based on the pollution index method. Water said to polluted if it cannot use according to its standard designation. The purpose of this research is to identify and find out the level of pollution contained in shallow well water used by communities in urban areas. Water quality index measurements using the Storet Method. This study uses ten samples with techniques Purposive random sampling with well water sources used by people in Makassar, especially in Untia Sub-District, Makassar, South Sulawesi. The number of samples used was 15 water samples taken each week with a total of 10 shallow well water sample points. The parameters measured in the study are Iron (Fe), Manganese (Mn), Total Coliforms, Total Dissolved Solids (TDS). The results of the study showed that the condition of shallow well water quality classified in category D, which heavily polluted which means it not recommended to use before filtering. The increase in parameters that have exceeded the maximum quality standard comes from natural sources and high domestic waste from community activities. Water pollution is a condition in which a water reservoir changes due to human activity ? the change caused by the entry of substances that should not be in the water.
