Abstract: Female aggression is a serious problem in most societies and is increasing these days in families. Female aggression has a negative effect on women as offender, their partners, children, and society in general. This paper aims to review the articles based on research that have been done on females’ physical aggression. It attempts to show that females are also physically aggressive as males. According to the existing literatures, the rate of females’ physical aggression is equal to those of males, and in some studies it is found to be higher than males. Based on these findings, it is concluded the rate of females’ physical aggression is either equal to or higher than males, but not necessarily less than males. [Report and Opinion 2010;2(4):1-6].

Abstract: Gum arabic is a leguminous tree species that is well adapted to sudan and sahelian agro-ecology of Africa. In Africa, gum arabic plays a significant role both in the rural life and economic activities of the people. The tree is valued for its high quality gum which is a foreign exchange earner. Nigeria is a major producer in the world. Her production declined in recent times from second world producer to third due to some challenges that could be controlled. The reasons for the decline and possible remedies are herein suggested. [Report and Opinion 2010;2(4):7-13]. (ISSN:1553-9873).

Abstract: Forest ecosystem plays very important role in the global carbon cycle. It stores about 80% of all above ground and 40% of all below ground terrestrial organic carbon. Deforestation has many ecological, social and economic consequences, one of which is the loss of biological diversity. The rapid deployment of remote sensing (RS) satellites and development of RS analysis techniques in the past three decades have provided a reliable, effective, and practical way to characterize terrestrial ecosystem properties. The present study focus on the monitoring of deforestation and forest degradation in Ranchi using geospatial approached. The multistage statistical technique incorporated with the satellite data of LISS III (1996 and 2008) gives a precise monitoring of forest degradation. This paper aimed to the analysis involved carrying out post classification change detection. Supervised classification of images of different epochs was carried out and then areas of the resultant classes compared for change detection. [Report and Opinion 2010;2(4):14-20]. (ISSN:1553-9873).

Abstract: Studies were carried out to determine the average grain sizes and evaporation rates of some Nigeria clay at oven drying temperature. The grain sizes were determined by sedimentation analysis using hydrometer method. The drying process was carried out at a temperature range: 80-1100C. The results of the sedimentation analysis show that the average grain sizes of Olokoro, Otamiri and Ukpor clay are 9.8195, 11.6 and 13.98 μm respectively. This implies mathematically that Olokoro Clay Grain Size < Otamiri Clay Grain Size < Ukpor Clay Grain Size. It was found that Olokoro clay has the highest water evaporation rate compared to Ukpor and Otamiri clay though of the three, it has the smallest grain size. This resulted from higher gangue contents of Olokoro clay which were burnt off during drying thereby enlarging existing inter-particle spacing and invariably enhancing the quantity of water lost by evaporation [Report and Opinion.2010;2(4):21-28].

Abstract: The effect of Pb-Sb-Cu alloy casting techniques on its electrical properties was investigated following casting of the alloys using using three different techniques; Technique A, Technique B, Technique C and cooling of the alloys after casting in the furnace and determining their electrical properties. Technique A, involves simultaneous addition of Cu powder and pouring of the molten Pb-Sb into the mould. Techniques B, involves addition of Cu powder intermittently as pouring of Pb-Sb into the mould was going on and Technique C involves pouring a stirred mixture of heated Pb-Sb alloy and powdered Cu into the mould. Copper addition to the base alloy was dispersion of the copper powder within the Pb-Sb matrix. The results of the investigation indicate that the electric current flow, conductivity, power dissipation, electrical resistance and resistivity from Techniques A, B and C alloys show a sinusoidal variation with each technique’s alloy due to different distribution pattern of the added copper. This implies that these electrical properties from each technique’s alloy are lowest and highest at different Cu additions. This is a clear indication that different electrical properties can be obtained on using the three different casting techniques depending on the optimum concentration of Cu required in the matrix to produce Pb-Sb-Cu alloy. Furthermore, the best technique for casting efficiently functional electrical components is dependent on the optimum concentration of Cu required in the matrix to permit achievement of maximum values of the associated electrical properties.

Abstract: Background: Pancreatitis is the most common complication following endoscopic retrograde cholangiopancreatography (ERCP), which can on occasions be severe and life threatening. Aim: To compare the efficacy of diclofenac, allopurinol 300 mg and allopurinol 600 mg for the prevention of post-ERCP acute pancreatitis. Patients and Methods: 130 patients were scheduled for ERCP either for diagnosis and or treatment of obstructive jaundice. Patients were randomized to receive a single dose of either: 100 mg diclofenac suppository immediately after ERCP (40 patients, 25 males, mean age 51.8±14.6 years), 300 mg oral allopurinol one hour before ERCP (30 patients, 16 males, mean age 53.3±11.5 years), 600 mg oral allopurinol one hour before ERCP (40 patients, 24 males, mean age 47.6±14.3 years) or no prophylaxis (control group) (20 patients, 14 males, mean age 46.9± 14.4 years). Serum amylase and lipase were measured immediately before, 4 and 24 hours after ERCP. Pancreatitis was considered when there was abdominal pain consistent with pancreatitis, coupled with the need for unplanned hospital stay or extension of the planned hospital stay by at least 2 days, with rise of serum amylase at least 3 times the upper normal level. Results: None of patients on diclofenac or large dose allopurinol developed post-ERCP pancreatitis, versus one patient on allopurinol 300 mg and two in the control group. Serum amylase and lipase increased significantly after ERCP in the diclofenac, allopurinol 300 mg and the control groups (p<0.05). In the allopurinol 600 mg group, serum amylase increased significantly at 4 hours after ERCP while serum amylase at 24 hours and serum lipase at 4 and 24 hours did not. Conclusions: high dose allopurinol (600mg) prevented the increase in serum amylase at 24 hours and serum lipase at 4, and 24 hours after ERCP. Both diclofenac and allopurinol 600 mg were associated with low incidence of post–ERCP pancreatitis. [Report and Opinion 2010;2(4):41-51]. (ISSN:1553-9873).

Abstract: Chad, a country located between the 7th and 24th degrees north latitude and the 13th and 24th degrees east longitude, presents as many developing countries multiple problems related to managing its water resources. In fact, several political, social, economic and environmental factors hinder their effective management. These factors deal particularly with the passivity of the actors in charge of water problems, an overlap of competences, the lack of financial means, the sectorial approach of solving problems related to water, the unilateral policy, the inefficiency of the main drinking water distributor (STEE), the sociopolitical context characterized by a pseudo instability, the lack of human capacities and the lack of appropriate texts and adequate structures. The consequences are dramatic and affect significantly the development process. Thus, the constant degradation of water quality and its unequal distribution are all tangible signs which indicate a poor water management, and contribute significantly to the population’s impoverishment in terms of health, urbanization, economy and trade. Some bilateral and multilateral actor’s initiatives which are centered on water supply, the irrigation program support, fishing, etc., come light this on the dark board of water management in Chad. The ratification by Chad of various international treaties related to water and its membership at the different organizations in charge of basins management (Niger Basin Authority, Lake Chad Basin Commission) constitute the advantages for national improvement framework of the integrated water resources management. The integrated water resources management (IWRM) is a systematic process for sustainable development, attribution and monitoring of the use of water resources in the context of the social objectives, economic and environmental. It is a very important and strategic framework for a double targeted process for achieving the Millennium Development Goals (MDGs) and the strategy of sustainable development as recommended during the World Summit on Sustainable Development (WSSD) in Johannesburg in 2002. The Governments need to plan the implementation this strategy to achieve the Millennium Development Goals (MDGs). [Report and Opinion 2010;2(4):52-61]. (ISSN:1553-9873).

ABSTRACT: Background: Hypothyroidism is one of the most common problems that develop in the thyroid gland which can be happened to females during pregnancy causing many diseases to the pregnant females and their expecting embryos. The two thyroid hormones levothyroxine (T4) and triiodothyronine (T3) are synthetic hormones used in the treatment of (hypothyroidism). Also another newly herbal medication called, Alvidar is used for the treatment of hypothyroidism which composed of herbal that help in improving the function of thyroid gland without any chemicals or hormones. In fact no adequate studies were been done in the human and animals concerning the mutagenicity of Alvidar, levothyroxine (T4) and triiodothyronine (T3) especially during pregnancy. Aim of the study is to evaluate the cytogenetic and mutagenic effect of Alvidar, (T4) and (T3) on the pregnant females and their embryos. Materials and Methods : Pregnant female mice were administrated orally with a doses (1.3, 0.13) and 0.07 mg/kg/day of Alvidar, T4 and (T3) respectively from day (1 to day 17 of gestation. Cesarean section were completed on (18) day of gestation, cytogenetic analysis micronuclei formation and developmental toxicity were examined. The results showed that Alvidar and triiodothyronine T3 caused a significant increase in the frequencies of chromosomal aberrations fetal toxicity micronuclei formation and fetal toxicity in the pregnant females and their embryos and these toxicity were highly increased in the (T3) group than Alvidar group compared with controls. While in the thyroxine (T4) group no mutagenic or embryo toxic effects were observed in the mothers and their embryos compared with control group. Conclusion: These results indicate that triiodothyronine (T3) hormone and Alvidar (herbal medication) had a cytogenetic and embryotoxic effects when administered orally during pregnancy. While levothyroxine (T4) hormone had no cytogenetic or embryotoxic effects during pregnancy. [Report and Opinion 2010;2(4):62-70]. (ISSN: 1553-9873).
