Proximate Analysis and Determination of Heavy Metals in Three Different Fishes in Ojo River
The aquatic environment is continuously at the mercy of man's negative impact pollution activities. Three tropical species a: Tilapia Fish (Oreochromis niloticus), b: Croaker fish (Micropogonias undulates), c: Catfish (Bagrus bayad) of the fish usually available in Nigeria was purchased, analyzed for proximate and heavy metal composition. The aim of this study is to determine the proximate analysis and heavy metals composition in the three species of fish. The fish samples were cut into chunks using the ratio of 3:1 of HCl and HNO3 to digest it. Inductively coupled plasma optical emission spectrophotoscopy (ICP-OES) was used for heavy metal quantification. The results of the proximate analysis for tilapia fish, Croaker fish and Catfish showed that the crude protein (17.29, 15.34, 11.03) %, ash content (0.88, 0.88, 0.97) %, total carbohydrate (CHO) (15.39, 11.08, 12.50) %, Crude lipid (7.28, 8.79, 10.35) %, and moisture content (59.18, 63.88, 65.17) % respectively. The estimated concentrations of heavy metals analysed for the Tilapia Fish, Croaker fish and catfish are Pb, Ba, Cr, Zn. The concentrations of the heavy metals determined are in order of Pb > Ba > Cr > Zn. The results of the proximate analysis obtained are in close argument with that in the literature which ranges from (0.065, 0.051, 0.051) % (0.046, 0.042, 0.042) %, (0.010, 0. 053, 0.007) % (0.028, 0.001, 0.041) % for crude protein, ash content, total carbonhydrate, and crude lipid respectively. In conclusion, the protein, lipid, CHO, fiber and moisture content in three (3) fish species Oreochromis niloticus, Micropogonias undulates, Bagrus bayad and the heavy metal determined varies among the different fish species and the highest percentage values for Pb, Ba, Cr and Zn are 0.061 %, 0.046 %, 0.053 % and 0.041 % respectively.

Psychological variables in alchoholic abstinent and relapsed people
Substance use disorders include substance abuse and substance dependence. Abuse refers to a maladaptive pattern of substance use not amounting to dependence, but lending to harmful consequences in personal, situational, social and interpersonal areas. The term substance dependence is related to physiological and behavioral symptoms of substance use. It is a cluster of physiological, behavioral and cognitive phenomena in which the use of a substance or a class of substances takes on a much higher priority for a given individual than other behaviors that once had greater value. Substance abuse may lead to addiction or substance dependence. Dependence almost always implies abuse, but abuse frequently occurs without dependence, particularly when an individual first begins to abuse a substance. Dependence involves physiological processes while substance abuse reflects a complex interaction between the individual, the abused substance and society. This study aimed to examine the prevalence of general self-efficacy, stressful events, style of coping and perceived support in a group of treated alcohol dependents but currently having a relapse to determine whether or not they differ from non-relapsed, on any of the measures. In sample, one group consists of forty patients who were diagnosed as ADS according to ICD – 10 criteria and currently either admitted at Alcohol De-addiction Centers, or seen at the OP Clinic for a relapse formed the experimental group (RLPS Group). In second group of forty patients who were met ADS criteria and currently abstinent for more than one year formed the control group (N-RLPS Group). The tools used in this study are Michigan Alcohol Screening Test, The General Self-Efficacy Scale, Presumptive stressful life events scale, Ways of Coping scale (revised) and Multi dimensional Scale of perceived social support were used for both the groups. The results indicated that, statistically significant positive correlation found between social support on self efficacy and significant negative correlation found between social support and stressful life events. It provided further evidence in support of the importance of certain clinical and psychosocial factors in relapse in substance dependence.

Reflection of the concept of martyrs and martyrdom in the sacred defense literature
The concept of martyr in the sacred defense literature of Iran one of the valuable concepts that is links the audience to religious and religious beliefs and flies the spirit of the audience from the depths of the beginning of the universe point and after exalting it take to the moment of again graft and connect at the end point. Looking at the history of the eight years of the imposed war, it can be seen that presence of enthusiastic forces and lover and martyrdom young people is one of the most effective factors in the resistance and victory of eight years of Islamic Iran which sacrificed their lives to defend the territorial integrity of the country and the sacred soil of the homeland and their admirable resistance against the enemies figured unique scenes of sacrifice, martyrdom and love which obvious footprint of writers, poets and authors in recording epics and sacrifices is quite evident at this time and it was essential to do this and tolerance, tolerance and failure in this necessity will have a huge amount of loser.

Remediation of Sanitary Wastewater containing Pb and Cd for Reuse in Irrigation
Heavy metals found in municipal wastewater can cause many problems for human hygiene and environment. So that it should be decontaminated from heavy metals before being used in irrigation. Many materials such as shall, alginate and iron oxide were used to remove heavy metals (Pb and Cd) from municipal wastewater. The results showed that, shall had the highest efficiency than the other materials in removing Pb and Cd from polluted water. Artificial polluted water was prepared by diluting stock solution of Pb and Cd of concentration of 1000 mg/l using distilled water. The prepared Pb and Cd polluted solutions had concentrations of 5, 10 and 50 mg/l. The remedy agents were added to polluted water at ratios of 1:100, 1:1000 and 1:10000. The solutions were gently agitated to equilibrium periods of 2, 6, 12 and 24hr. Generally, the efficiency of remedy agents to remove heavy metals increased as the addition ratio increased. Percentages of Pb removed by mudstone at addition ratio of 1:1000 were 86 and 32.8% for 10 and 50 mg Pb/l, respectively, in a reaction period of 2 hrs. Regarding Cd, the removal % was 84 and 66.4 for 5 and 50 mg Cd/l, respectively, in 2 hrs. On the other hand, the Percentage of Pb removed by iron oxide and alginate were as low as 0 and 30 %, respectively. Generally for all treatments, the removal efficiency decreased as heavy metal concentration in polluted water increased. Shall was the most effective material in decontamination of heavy metals polluted water and it could be recommended to be used to decontaminate wastewater.

Removal of Methylene Blue dye from aqueous solution onto novel adsorbents: Molybdenum dicarbonate-filter paper and Molybdenum dicarbonate-activated carbon composites
Two composites - 1) Molybdenum dicarbonate-filter paper and 2) Molybdenum dicarbonate-activated carbon were synthesized and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray analysis EDX. Using the method of UV-visible spectroscopy, the removal efficiences and adsorption capacities of these composites towards the removal of methylene blue (MB) from aqueous solution were compared. The findings of the MB adsorption with these composites (I and II) indicated equilibrium adsorption in less than 5 minutes. Composites I and II have MB removal efficiencies of 87% and 96.25%, respectively, and their estimated adsorption capacities at 20°C are 432 mg g-1 and 481 mg g-1. The adsorption process of MB onto Molybdenum dicarbonate-filter paper (composite I) suited well with the pseudo-first order and pseudo-second order kinetics and conformed to intraparticle diffusion model for Molybdenum dicarbonate-activated carbon composite (composite II). Adsorption of MB onto composite I aligned with both Freundlich model and Tempkin models due to higher values of correlation coefficients and fitted well with Langmiur model for composite II. Adsorption process was found to be endothermic and spontaneous in nature. The adsorption results revealed that these composites could be employed as effective adsorbents to remove dyes from industrial effluents.

Review on the Black Hole Theory
In this study a quick summary for the back-hole theory was presented. It was presented earlier in from of graduation project at university of Bahri, college of applied and industrial sciences department of physics, Khartoum, Sudan by the second author and under supervision of the first author. Black holes were once a star shining for years, before eventually collapse on their core forming the BH. There are three cases for a star non stable end is either a white dwarf, a neutron star or a black hole which is completely depend on the mass of the previous star which are called a compact star due to their highly condensation states. In this paper a quick summary for the theory was presented.
