The prevalence of Pediculosis capitis human head lice, among children is a worldwide public health alarm. The study aimed to assess the prevalence of head lice and associated risk environmental and personal factors among primary school girls. Study sample included 590 students from different primary school grades. The results showed that (12.2%) 72/590 of students were infected with Pediculosis capitis. A high rates of infestation was observed among students, who had a long hair, poor family and illiterate mother’s (30.2, 28.6 and 28.6%, respectively). However, association of pediculosis capitis with socioeconomic and personal factors showed that pediculosis capitis had a significant association with place of residence, school grade, hair length, previous infection, sharing of instruments, income of parents and education of parents level. While no significant differences could be found between infestation and nationality, frequency of hair washing, cleaning materials for hair washing, mother’s occupation, number of children in family and number of people sharing room. The study recommended that the parents and teachers should receive training about the danger of infection and its distribution in family and school in order to prevent it.

This study aims to study the ability application of nonlinear Auto-Regression model with exogeneous inputs (ARX) in forecasting time series monthly temperatures changes in Delta, Egypt for 49 years (1960 to 2009) monitoring data. Three methods are used to estimate the optimal parameters of ARX model identification which are the normalized Least Mean Square (LMS), artificial Neural Network (NN) and Wavenet Neural network (WN). The time series temperature changes from 18 weather stations in Delta are used to compare and estimate the best method for the temperature change models. The models results indicate that the worst case solution for ARX model is LMS while the WN is found to be better than NN in the training period. The NN is found an acceptable performance for training and testing periods. The 95% auto-correlation function for the residuals models shows that there is no loss of information is observed for the applied ARXNN model; however, the ARXNN technique can be successfully used to predict the monthly temperatures of any site at the Delta area in Egypt.

Tropical wetlands are one of the most dynamic natural sources of atmospheric methane (CH4) but the CH4 emission data is still scanty to quantify and elaborate the process of CH4 emissions from natural freshwater tropical wetlands. In view of this, the present study attempts to estimate the CH4 emissions from two natural tropical wetlands of Uttar Pradesh, India to further augment the CH4 emission database for tropical countries for improved understanding of CH4 cycling in tropical wetlands. This study elucidates the importance of temporal, site specific and zone-wise dependence of CH4 emission in a wetland. Significantly higher CH4 flux in the summer season than monsoon and winter season at both the locations (p<0.05 for shallow water, deep water and exposed wetland soil zone) clearly define the importance of temperature, water depth, dissolved oxygen, redox potential, biological oxygen demand and plant biomass in regulating the seasonal CH4 flux. Spatial analysis revealed that higher mean annual CH4 flux from the Nawabganj lake (153.5±23.2 mg mG dayG) as compared to the Keetham lake (80.0±11.8 mg mG dayG), is attributed to enhanced anoxic conditions at Nawabganj lake owing to shallow, static and shrinking water base, high plant mediated CH4 flux and boosted autochthonous organic matter production by dense aquatic vegetation present in the lake chiefly including Eleocharis dulcis, Nelumbo nucifera, Ipomoea aquatica. Zone-wise, shallow water zone contributes maximum to CH4 flux than deep water and exposed wetland soil zones at both the sites due to high biological oxygen demand, heavy vegetation infestation and decreased values for water depth, dissolved oxygen and redox potential.
