Can Plant Product be Substitute for Artificial Oral Contraceptive Pills?

Kadam Asha* and Gaykar Balasaheb

Contraceptive methods mean birth control and fertility control methods or devices which used to prevent pregnancy. There are many categories of birth control methods but some having negative influence or risks and some safest and healthiest options. In the present study, we surveyed 269 women from Ahmednagar region and we found that among the 269 women, 179 women were used artificial contraceptives and rest of the women were not used any type of contraceptives. According to the feedback of these women only some having satisfaction and remaining most of women are not satisfactory with these contraceptives, because of high risk of cervical cancer, blood clots, cycle irregularities, irregular bleeding, loss of sexual function, vaginal infection etc. Hence according to survey, we analyse that many women turn to birth control pills because they are not aware that there are safer options available.

Comparative Effect of Petroleum Products and Biomass Fuel Exposure on Serum Lipid profile and Atherogenic Indices of male Albino wistar Rats

Ude Tochukwu*, Meludu Samuel Chukwuemeka, Dioka Chudi Emmanuel, Chikezie Onyebuchi Desmond, Awalu Chimezie Joseph and bekailo Sylvester Nnaemeka

The effects of petroleum products and biomass fuel on serum lipid profile and atherogenic indices were investigated in male wistar rats. Fifty adult male wistar rats were randomly assigned to five groups of ten animals each. Rats in group A served as control (exposed to fresh air). Group B, C, D and E were exposed to inhalation of kerosene, gasoline, liquefied petroleum gas and biomass smoke (wood smoke) respectively. All the exposures were done using whole body exposure chambers 70cm x 60cm x 60cm measurement for six weeks. Five millilitres of fasting blood sample were collected at the end of six weeks and used for analysis of lipid profile using mindray BS 120. Atherogenic indices were calculated using the appropriate formula. Values were analysed statistically using SPSS version 23.0. The result shows significant increase in the serum total, LDL, VLDL cholesterol and triglyceride concentrations of test groups relative to control (p<0.05), while inducing a significant decrease in HDL cholesterol though the effect appear to be more pronounced with kerosene exposure. The exposure also led to significant increase in CRR, AC and AIP (p<0.05). These results suggest that petroleum products and biomass fuel exposure could potentiate the risk of atherosclerosis through elicitation of dyslipidaemia.

Hydrochar for Industrial Wastewater Treatment: An Overview on its Advantages and Applications

Ahmed Hesham, Yasser Awad, Hossam Jahin, Sabry El-Korashy, Shaimaa Maher, Haitham Kalil and Gasser Khairy

Water pollution is one of the environmental challenges facing the world society. Consequently, the pollutants both domestic and industrial wastewater are identified as an environmental threat. Hydrochar (HC) appears as a cost-effective and eco-friendly solution to this environmental threat. HC is the solid produced from the wet pyrolysis process for biomass that is rich in carbon in a sub-critical liquid phase, called the Hydro-Thermal Carbonization Process (HTC). This review aims to address the possibility of using HC as the most effective solution to the industrial wastewater. HTC has proven a greater yield than dry pyrolysis (30%-60% wt). To date, HC is listed as a promising lower-cost alternate adsorbent for removing wastewater pollutants. In Egypt for example, only few studies have been published investigating the properties of HC and its environmental applications. In this review, we will shed light on the preparation, characterization, and previous studies on the development and recent applications of HC. In addition, we will discuss the challenges to produce HC at a commercial scale. To the best of our knowledge, there is only few research studies addressing the HC production in the Middle East countries. Therefore, the door is still opened for more research on developing production techniques on HC from different biomass, and implementation in various environmental applications

Ozone Layer Depletion and its Consequences on Humans: a Review

Sulaiman Bin Abdullah

Ozone (O3) is a stratospheric layer that assumes significant job in offering help to people for their endurance. It is a basic factor for some worldwide, natural and ecological wonders. The ultra-violet (UV) beams discharged from sun are caught by ozone and in this manner give a stable ontological structure in the biosphere. Different anthropogenic exercises, for example, emanations of CFCs, HCFCs and other organoincandescent lamp lead to the exhaustion of ozone. Ozone exhaustion is enabling the UV radiation to earth surface. The introduction to these radiations is seriously influencing all living things on earth, particularly the people. Perpetual or transitory visual deficiency, skin malignancy and insusceptibility concealment are the principle impacts of these radiations revealed by different scientists on people. The possibilities of ozone recuperation are as yet unfamiliar. The present circumstance of ozone portrayal requests dire healing measures to secure lives on this planet. Chlorofluorocarbons, halons and methyl bromide are largely critical ozone exhausting substances controlled under the Montreal Protocol. Satellite perception frameworks help to foresee future changes to the ozone layer. In view of understandings under the Montreal Protocol, the ozone layer is relied upon to recoup toward the center of the twenty first century. Research should be done to evaluate that how different alternatives of cooling agents (chlorofluorocarbons) tend to decrease the emission of chlorine.
