Physiochemical parameters of river water and groundwater samples from Morang and Gumani river basin, Jharkhand was assessed to find out their suitability for domestic and irrigation use. Water samples were categorized as Ca2+ – Mg2+ – HCO3- hydro-geochemical facies and cation and anions are mainly derived from the rock. Individual concentration of Na+, Ca2+, Mg2+, K+ , Cl-, F- and SO42+ are within the prescribed limit of WHO and BIS standards. However, NO3- of one groundwater is higher than the permissible limit. River and groundwater is safe for irrigation as per the Soluble Sodium Percentage (SSP) or %Na, Sodium Adsorption Ratio (SAR) and salinity hazard parameter. Magnesium hazard (MH) river water is not suitable for the irrigation and special care needs prior to use.

The purpose of the study was to establish English student teachers’ knowledge of writing strategies to facilitate instruction of writing skills. The specific objectives were: to find out introduction strategies used by participants when writing essays, to establish strategies used by participants to ensure coherence of the written essay and to examine conclusion strategies used by the participants in essay writing. A total of 37 fourth year English student teachers’ were used in the study. The instrument used for data generation was document analysis of written essays. The study revealed that the student teachers lack sufficient knowledge of writing strategies. The study recommends that: English Language Teacher Educators should design a course about communication strategies for effective essay writing to be taught to student teachers specializing in English to equip them with both content and pedagogical knowledge for effective teaching. Examining of the course should include writing essays to motivate students to practice and master writing strategies for effective communication. English language teacher educators should coordinate and ensure that the content courses taught by other schools apart from the school of education are relevant and meet the needs of English Language Teaching in Kenya.

This paper examines the legal framework for copyright protection in Nigeria and the USA. This work critically analyses laws in both countries for copyright protection. The USA and Nigeria Copyright Acts extend protection to computer software by treating software as a literary work. Copyright based industries operating in the country contribute trillions of naira to Nigeria’s gross domestic product. Despite the enormous benefits which the country has derived from computer related products, Nigeria remains the largest piracy destination and markets in the world though these same products are ostensibly protected by the Copyright Act, Similarly, according to a study titled: “Addressing global software piracy” conducted by Microsoft in partnership with the US government agencies and consumers in 2010, software piracy recorded $750 billion dollars in lost revenues and millions of lost jobs in software industries. Causes of piracy and counterfeiting have been discussed and recommendations have been made on how to eliminate them.

Hydrostratigraphic mapping and results of pumping test analysis were used to investigate groundwater occurrence and the hydraulic properties of the aquifer systems in the Wuro Juli well field, near Gombe Metropolis, Gombe Sub Basin. The well field is comprised of a set of 13 deep boreholes developed to improve public water supply to Gombe Township. The delineated aquifers have several formation boundaries that inhibited lateral continuity of groundwater flow. At a discharge rate of between 43.20 m3/day and 613.44m3/day, the specific discharge (q) and Hydraulic Conductivity (K) values varied in the range of 1.17-2.03m3/day and 2.75 x 10-2 - 2.06 x 100 m2/day, respectively. The Application of both Chow’s method of Drawdown Analysis and Jacob’s Residual Drawdown Method to drawdown measured during multiple pumping tests in the well field yielded very low Transmissivity (T) and Storativity (S) values. T and S varied in the range of 3.13 x 10-5 - 3.50 x 10-4 m2/sec and 4.40 x 10-8 - 4.00 x 10-7, respectively. The analysis of the distance-drawdown data indicated that a resultant drawdown due to simultaneous pumping of two wells for about 200 minutes ranged from about 30m near the pumping wells to 0.50m over the more distant segments of the radius of influence. The low Transmissivity (T) and Storativity (S) values of the water supply aquifers in the well field caused very low range of cone of depression, culminating in huge drawdown values within some of the pumped wells. This tight cone of depression would limit the actualization of the projected abstraction rate of 4492.80m3/day (187.20m3/hr) required to temporary solve water supply problems in Gombe Town. Structural discontinuities and in particular very low aquifer recharge through rainfall were other important parameters that contributed to the limitation of the groundwater potentials of Wuro Juli well field.

Visual cryptography is special type of technique for encipher the confidential visual information (e.g. printed text, handwritten notes, and picture) in such a way, that decipher can be performed by human visual system (HVS) without any complex process, providing high security. In this paper a simple but robust visual cryptography scheme is proposed. In this scheme the secret is encrypted using symmetric key encryption algorithm, and then this encrypted data will be hidden into an image file, divided into parts called shares and then they are distributed to the participants. Thus accomplishing both data encoding and hiding. Only piling of shares does not revile the secret until shares are stacked together in a particular fashion and provided with the key. It can be used to hide the original secret information from an intruder or an unwanted user. The shares are very safe because separately they reveal nothing about the secret image. The algorithm proposed by this scheme reduces a considerable time for encryption and decryption in a much easier way and ensures the lossless transmissions of images. The proposed encryption algorithm in this study has been tested on some images and showed good results.

Vermicompost sample was produced by Eudrilus eugeniae in cowdung was collected from the Department of Biology, Gandhigram Rural Institute- Deemed University, Gandhigram. The sample was serially diluted and bacterial cultures were isolated and they were identified based on their characteristics as Micrococcus sp., Alcaligens sp., Tricoccus sp., Azomonas sp., and Paracaccus sp. These five bacterial isolates were subjected to screening for Indole acetic acid (IAA) production and all the bacterial colonies showed positive results for IAA production. Among the five isolates, Alcaligens sp. produced more amount of IAA (10µg/ml) when compared to all the other organisms. Hence Alcaligens sp was chosen for plant growth studies at 1 to 5 ml concentration. The isolate at 5 ml showed improved germination percentage of Vigna unguiculata seeds and it also showed improved shoot length (13.25 cm), root length (4.99 cm), number of leaves (5.0), chlorophyll content of leaves a-(0.0025 mg/g), b-(0.177 mg/g), total chlorophyll (1.351 mg/g), fresh weight (1.07 g) and dry weight (0.08 g) on the 7 day when compared to the control and the lower concentrations (1,2,3,4 and 5 ml).

A survey on fungal diseases shows that vaginal yeast infection is most common fungal disease in Raipur city. A general survey on vaginal infections or urinary tract disorders showed that 75% of ladies suffer from vulvovaginal Candidiasis at some point in their life time. Though Vaginitis is usually not a serious disease but it can be annoying and uncomfortable. The main objective of this paper is to get acquainted with the symptoms, diagnosis, and treatment procedure with some home remedies involved in Vaginitis and to study the main fungus responsible for this disease Candida albicans. As 8 out of 10 women in India according to WebMD and other parts of country get this infection and sometimes if not properly diagnosed takes a serious form which is more dangerous. During survey it was found that 40% of women report to their doctors and 20% of women go for self medications. This infection is less common in girls before puberty and post menopaused women. It is common in women of reproductive age group between 20- 45 years and therefore reproductive hormones, particularly estrogen, is thought to enhance the proliferation and attachment of Candida to the vaginal inner lining. Sometimes however, thrust can occur in post menopausal women if they have uncontrolled diabetes, hormones replacement therapy, severe chronic disease or if they use antibiotics, immunosuppressive agents or Tamoxifer a drug used in breast cancer. Hence it is very important to recognize and differentiate the symptoms and consult your physician. Vaginal yeast infections can be cured with proper diagnosis and treatment. At present time it is not possible to predict reoccurrence of this disease but a comprehensive management plan incorporating medical and immunological care remains the most likely means of providing long term disease control for yeast Vaginitis.

Magnetic resonance Image (MRI) is a medical image method use in radiology to visualize internal body structures like tissues. MRI method provides high-quality contrast effect to visual tissues of brain and MRI contrast is enhancing appearance of tumors in brain. In this survey compared the CLIC, EM, AFCM, Bias Field Estimation, SFKFCM, MFCM and FLGMM methods for accurate brain segmentation in MRI images. CLIC method to evaluate metric tissue classification and estimate bias field minimizing energy, optimal bias field derived smoothness of CLIC method. It’s applied for fully automated applications. AFCM applied on corrupted images in reality accurate in classification and partial volume effect. MR data corrupted truth brightness variation in each component. AFCM implementation is faster than other methods one major problem in AFCM method is to look for clusters of the same shape, size and increased complexity. Bias corrected FCM method with spatial neighborhood regularization period and its time taking; lacks robustness to noise is main problem of the method. In GKFCM method with a spatial bias correlation can automatically learn parameters by prototype driven learning scheme and this method is effective more robust to noise. SFKFCM method for segmenting brain MRI images and correcting spurious variations, to improve the separability of observed data, fast clustering scheme improve speed up process and execution time is reduced improved clustering results. MFCM for adaptive segmentation and intensity correlation of MR images and automation available for the segmentation of MR images into tissues classes correcting interscan intensity inhomogenetics. MFCM leads to increased improvement in quality of 3D brain structures and visualization. GMM voxel intensities in each target region, its lack of taking spatial information and uncertainty data may produce poor segmentation result. To overcome problem in segmentation FGMM concept is proposed for uncertainty data and parameter quality improvement. The integration of the weighted GMM energy functions in the entire image and uses a truncated Gaussian kernel function to incorporate spatial constraints into local GMM employ the fuzzy membership function to balance each GMM segmentation process. FGMM reduced noise, low contrast, bias field and improved segmentation result compared with all other methods proposed by previous researches.

It depending on the size of the business and business network also, every minute downtime can more affect the productivity of the business employee and the business system that use the network. The address this within the adaptive security appliance (ASA) product line, Cisco offers high availability through a series of failover capabilities. When configured, they allow a deployed ASA to be mated with another ASA, which combine to offer little downtime if one of them encounters of failure [1]. This paper introduces the replication of data, it means both units carry data traffic and it also introduces how to secure our interesting traffic over the internet. VPN mainly used for security purpose we use VPN in many thing and many fields. It provides the secure and private network connection through the public internet; the VPN protects our data in many ways. VPN tunnel is an encrypted connection between our device and VPN sever.

Community based tourism is taking its place in the world as an alternative to traditional tourist destinations, especially in developing countries. This form of tourism allows for greater contact with the local community and for the tourist to experience new sensations while enabling the economic and social development of the geographic area. In this paper, the results of fieldwork carried out in the Latpanchar Village (Darjeeling District of West Bengal, India) is presented, assessing the opinion and perception tourists visiting this area have of both the quality of the services offered by community based tourism enterprises, as well as the potential of the tourism resources in the area. The main results of the investigation endorse the quality of services offered to tourists by local businesses and highlight the hospitality of the local community, a key element for the development of this kind of tourism, particularly in different villages of this district. Similarly, it highlights the tourist satisfaction with services received and the need to strengthen the training to tourism staff through aid. The originality of this research comes from analysis of the demand made on a concrete base for Latpanchar, a village which is producing a huge economic development through the community based tourism approach.
