A fixed-bed reactor system was used to study the adsorption capacity as a function of pressure and flow rate. X-ray fluorescence spectroscopy (XRF) was used to determine quantitatively presence of elements. Also the Scanning Electron Microscope (SEM) analysis had been carried out for structure. Results of the experiments showed that the breakthrough adsorption capacity for orange peel powder was 2.604 mmol/g for 5 g and 10 LPH of CO 2 . For orange peel carbon the breakthrough adsorption capacity for 14 LPH for 7 g was 5.0843 mmol/g.

Biofuels are the most important alternative fuels. Manufacturing processes for biofuels have made it possible to reduce greenhouse gas (GHG) emissions from well to wheel. There are a number of popular alternative fuels for use in internal combustion (IC) engines, including biodiesel, bioethanol, and bio methanol. Biodiesel and petroleum diesel fuel blends in compression ignition (CI) engines have received a lot of attention. Biofuel is any liquid fuel derived from "biomass," such as plants and animal waste. Biofuels replace gasoline and diesel. Biofuels are promising because the carbon dioxide (CO2) they emit is recycled through the environment. Biofuel plants collect CO2 from the air and release it when burned. In principle, biofuels can be a "carbon neutral" or "carbon negative" means to power automobiles, trucks, and planes. Biofuels can reduce CO2 emissions without requiring many infrastructural changes. They can be used in existing cars and mass-produced from biomass like chemicals and pharmaceuticals. Future biofuels may be moved using current pipelines. Making carbon-neutral biofuels is difficult. Fermentation, processing energy, transportation, and even plant nutrients can produce CO2 and other greenhouse gases before biofuels are consumed. Biomass agriculture can have climate consequences if it replaces CO2-storing woods. How biofuels are generated and used affects their potential as a climate solution.

In addition to this shortage, which exacerbates the problem is the large increase in the population of Iraq, in addition to the great problems that the country has experienced, especially the fierce confrontation with ISIS terrorist gangs, which drained a lot of Iraq’s human and material energies and negatively affected the energy reality in our country, not to mention the All or most of our electric power plants run on heavy fossil fuels and have old technology tracks. Iraq has power shortages, and there are various obstacles that must be solved in order to keep up with projected demand. Based on the results of this study, it appears that solar, wind, and biomass energy are underutilized at now but have the potential to significantly contribute to Iraq's renewable energy future.

Due to the large quantities of plastic manufactured in different parts of the world and the difficulty of decomposing plastic products, which have a decomposition period of decades. As well as considering the marine environment as one of the most vulnerable ecosystems to pollution with plastic waste, and at the same time, people do not pay attention to this disaster, which directly affects the rest of the environmental systems and causes serious changes to the ecosystem. In this paper, we tried to review some of the direct effects of plastic waste on marine organisms such as coral reefs and sea turtles. As well as review the impact of these organisms' damage on the ecosystem in general. This paper recommends some solutions that will reduce the huge quantities of plastic waste and how to treat it and try to legalize production to control the amount of plastic waste previously produced during the past decades. Contribution/ Originality: This study contributes to add some ideas to existing literature studies in the field of environmental pollution of the marine environment due to plastic, while highlighting some solutions that could contribute to reducing this type of pollution. 1. INTRODUCTION Plastic is considered one of the most harmful substances in the environment and at the same time, it is one of the most consumed materials daily all over the world [1]. Plastic has lightweight, highly durable, strong, and cheap price. According to United Nations UN reports, one million bottles of drinking water are consumed every minute, and five billion plastic bags every year [2]. Half the amount of plastic produced is designed for single use only and thrown after use. Plastic production began in the 1950s till the 1970s was small quantities where waste plastic was

Comparing amphetamine derivatives, METH is stronger and has a more permanent effect on central nervous system in human brain (1). Easy preparation and low price of METH has increased its abuse (2), such that today, we have encountered the unpleasant social consequences of drug abuse in Iran which does not subside (3). There are different reasons of abusing METH such as increasing the strength to bear a long period of a heavy labor (4), for fun and sexual intimacy and also losing weight. It seems that the main users of METH in Iran, abuse it to have fun and develop sexual satisfaction (3). The use of METH among women is significantly associated with an increase in high risk sexual behaviors leading to increased sexual transmission of diseases such as HIV/AIDS and increased abortion rate (5,6). Recently, the adverse effects of METH on the reproduction system has got attention as METH is considered to be a teratogenic and embryotoxic drug (7). Various studies have been done studying the effect of METH on testis tissue and spermatogenesis process, which showed the reduction of spermatogenesis process (8) and also induction of apoptosis in seminiferous tubules in rat testis (9). In another research, the effect of ecstasy, as one of the amphetamine derivatives, on oocyte quality and fertilization rate was studied and the results showed the probable effect of this drug on the oocyte quality and fertilization rate (10). This study was designed to evaluate the effect of short and long-term METH administration on oocyte quality, fertilization rate and the quality of embryo in pre-implantation stage in mice. Materials and Methods All reagents and materials were purchased from Sigma chemical Corporation (St. Louis Mo, USA) except where mentioned otherwise. Also T6 culture medium protocol was obtained from manipulating the Mouse Embryo book.

Initially, its chemical and physical properties were determined before it was used for the removal of Acid Black 1 and Acid Blue 113 dyes. A batch sorption study was carried out in order to obtain the optimum isotherm model. The monolayer maximum saturation capacities of AB1 and AB113 dyes based on Langmuir isotherm model were determined to be 458 mg dye/g carbon and 286 mg dye/g carbon, respectively. Adsorption of dyes was also studied in a continuous-flow state using a fixed-bed column of activated carbon. The effects of operating variables such as flow rate, bed depth, and dye concentration on the column operation were studied. Data confirmed that the breakthrough curves depended on flow rate, bed depth, and initial dye concentration. Column behavior was investigated using Thomas Model and model parameters were determined by a non-linear regression method. The Langmuir and Freundlich isotherm models were used to fit the experimental data. The best fit of the adsorption isotherm data was obtained using the Langmuir model for both dyes. The results showed that Thomas Model was suitable for the description of breakthrough curves under the experimental condition. The column adsorption capacity was also compared with equilibrium adsorption capacities for each dye.
