In present investigation shows the seasonal changes in RNA : DNA ratio in different tissues of Katelysia opima. The RNA and DNA ratio in the calm was found increased in adductor muscle, gonad and hepatopancreas than gill, mantle, siphon & foot at the time of gametogenesis in early monsoon. Similarly in that period the protein content was also increased in particular tissuses. In monsoon, the gametogenesis was triggered by temperature and the requirement of protein was increased, so the RNA content was also increased during that period and DNA was dependent on the increasing and decreasing content of RNA.

This study was carried out to determine the serum concentration of Creatine Kinase MB in obese subjects attending University of Port Harcourt teaching Hospital. One hundred and eighty five (185) obese subjects of BMI > 30 had their Creatine Kinase MB determined by enzyme linked with immunosorbent assay and compared with 160 age and sex matched controls. There was significant difference in the Creatine Kinase MB concentration of 2.76 ± 0.30 obtained in obese subjects compared with 2.91 ± 0.29 in control (P > 0.005). The result of this study suggests that serum levels of Creatine Kinase MB are lower in obese subjects.

This paper presents the design and implementation of sharpening of maximally flat cascaded integrator comb compensation filters. Cascaded integrator-comb (CIC) digital filters are computationally efficient implementations of low pass filters. No multiplication characteristic makes them popular in hardware devices. The modified sharpened cascaded integrator comb compensation filter is used to improve magnitude response and gain. For narrow and wide-band compensation second-order and fourth-order linear phase filters are considered. Power-of-two decimation factors of CIC filter is M and number of adders are depends upon decimation factor. Closed form equations for the computation of the filter coefficients are provided. The new technique delivers gain and stop band attenuation correction comparable to existing techniques.

Pre-emption, right of possession, and one of the two partners, the property is non-transferable, and pre-emption, the excesses and the pair is strengthened, and the evidence of that agreement, because of tradition and the public, and contrary to nature principle. Conditions, non-transferable, being capable of being divided, joint property, common to transfer shares to buy and sell, buy or sell a joint share transfer of common shares, the limited number of participants, not more than two persons, is due to be Muslim and be able to pay the price . For absent, ignorant, beggars, insane, kids, travelers and headed orphan, is fixed, and for being a neighbor to neighbor, is not constant, and also for those who are devoted to them, not as a pre-emptive . Qualities get it, be immediate, definite and certain to bring about the condition, and the purchase and sale ( the authority and dominance of the demise of the person signing ) flows, and how it is transmitted, is the inheritance, the heir to the size of each share would be before citing the preemption, the client do anything, could be due to demand, and is perfectly in sales, if before the violation, the customer is guaranteed and if a natural disaster, provided both are mediators, the catch and release it, and the difference in the price quote, the customer promises to share, and, in some cases, such as if the intermediary does not claim the power, and the transmission is not part through sales and property usurpation if preemption is void, and survivorship Eghaleh and terminate the transaction can not be canceled and the sales price is the same as the wedding date has been set.

Water resources management is a predominant problem for future development in today’s condition. Development of new technologies has extended the possibilities of wastewater reuse concept. Therefore, reuse of treated wastewater effluents has emerged as a renewable resource that increases in amount with the increase in water use. Inline with that, the wastewater treatment plants have come forth to implement tertiary filtration of secondary treated effluents to improve water quality for possible reuse in irrigation. In this present study, the characteristics of the tertiary treated effluent from granular activated carbon and pressure sand filtration are analyzed. The performances of the tertiary units are also monitored. The tertiary treated effluent is analyzed for applicability in agricultural purposes. The results revealed that treated sewage is applicable for gardening purposes but the removal of microbiological quality of the treated sewage was not at the satisfactory level. For removal of microbiological population, disinfection system such as UV/Ozonation can be installed for improving the quality of treated sewage.

The present paper focuses on the study of cladocera of nira left bank canal and Tarangawadi lake of indapur and baramati region cladocera are fresh water zooplankton inhabiting oll the niches of fresh water bodies. The study of cladocera has being fascinating subject to the biologist. In the digestive tract of most fishes one to ninty percent cladocera are found. Hence in order to increase pisiculture study of cladocerans are important. The water samples were collected between 8 am to 11am during the year Dec 2010 to august 2011. The collected samples were preserved in 4% formalin to study diversity of chydoridae family. The species identified by standard key method. About 17 species have been recorded identification was based on the presence of body parts

A new semi organic nonlinear optical crystal, L-Alanine potassium nitrate has been synthesized and good optical quality single crystals were grown by slow evaporation technique. The growth conditions of the crystals are studied and the grown crystals are confirmed by powder X-ray diffraction studies. The grown crystal was characterized by using powderedXRD, FT-IR, UV–Vis–NIR, EDAX, and TG–DTA. The sharp peaks from powdered XRD spectrum shows high crystalinity of the grown crystal. The presence of various functional groups was confirmed by FT-IR spectroscopic technique. The UV–Vis–NIR spectrum indicates that the crystal has very good absorption in the entire visible and near IR region spectrum suggesting the suitability of the material for NLO applications. The decomposition temperatures and mass loss have been estimated from the thermo gravimetric analysis. The presence of potassium in the compound and composition of grown crystals was confirmed on the basis of energy dispersive analysis of X-ray (EDX).

Learning disability of students is one of the major problems faced by teachers in a normal classroom. Due to learning disability a child needs extra care and attention from the parents and teachers as well for getting proper learning. Present study aimed to investigate the role of teachers in handling learning disable students in a normal classroom at primary education level. The study was conducted on 80 primary school teachers of Abbottabad (Pakistan). It was found that although, in general, according to pedagogies, teachers should consider learning disabilities of students in class room; but teachers face problems in handling these students due to not having proper training in this context.

Many children are refusing to attend school or have problems remaining in the classes for an entire day. Refusal is associated with classroom climate factors and if not managed well they lead to multiple socio-economic risks spanning into adulthood. This study sought teachers’ views on classroom determinants of school refusal behaviour among lower primary schools in Nandi East district with emphasis on class dynamics. The study adopted a descriptive survey research design in which variables were studied as they are in the field without manipulation. The accessible population consisted of all the 282 public lower primary class teachers in the district. The final sample size of 152 was determined by employing Stein’s method. Stratified and simple random sampling methods were used to get the participants. Structured and semi structured survey questionnaire were used to collect data from class teachers. Cronbach’s Coefficient Alpha was used to determine the reliability of research questions; which established a reliability coefficient of .872. Descriptive statistics used to analyze quantitative data were percentages and frequencies. Statistical Packages of Social Science (SPSS) programme version 17 aided in analyses. The findings were summarized and presented in tables and figures. The study established that teachers consider the following dynamics as triggers of refusal: getting poor marks which lead to frustrations, learners inability to bring out their problems well, teachers forcing weak learners to repeat classes and learners getting demotivated because achievement and performance are not praised or rewarded. The study recommends the in -servicing of education stakeholders on nature of school refusal, improving provision of instructional materials to learners with special needs and improving school inspection.

In recent years, increased water use and decreased precipitation have led to increased pressure to groundwater resources, this its quality decrease. Therefore, the main reasons for studying groundwater are potential hazards for groundwater contamination and protect it (ground water) from contamination: te main purpose of this research is the assessment of spatial and temporal trends in ground water quality in Shahr-e-Babak plain to besides of measurement of variation trends, by identifying contaminated regions (for agricultural purposes) issues and problems raised due to contaminates water usage could be prevented for this reason, data related to qualitative parameters of ground water such as EC, SAR, TDS during inventory period 2002-2009 were used. After fitting the best variogram model to empirical model of each of qualitative parameters of Ground water, by Arc GIS 9.3 software and by using Kriging interpolation method. Zoning maps of the region were prepared. Also the water of the region in the view point of agricultural use, was assessed using Wilcox and FAO method results obtained from this research showed that from comparison between Kriging interpolation and inverse distance weighted, Kriging method have the higher precision (based on low RMSE and MAE) than IDW. Also result from water classification based on Wilcox show the increased contamination trend especially in southern parts, and generally in this period the water of the region is classified as moderate-quality water, and also in FAO method contamination trend of waters in this region is increasing and in this method southern parts of this region are classified as the most contaminated parts (water classed with high salinity) of the region. The reasons of contamination of southern parts of the region are the type of Geological of the region and also high agricultural activities.
