The optimized molecular structure, vibrational frequencies, corresponding vibrational assignments and thermodynamic properties of N-(4-methoxybenzylidene) aniline (N4MBA) have been investigated by using ab initio HF/6-311++G(d,p) and DFT/B3LYP method at 6-311G(d,p) and 6-311++G(d,p) basis sets. The energy and oscillator strength calculated by TD-DFT are in line with experimental findings. Moreover, we have not only simulated HOMO and LUMO, but also determined the energy band gap. The stability of the molecule arising from hyperconjugative interaction and charge delocalization has been analyzed using natural NBO analysis. Besides, Mulliken charges were also calculated. IR and Raman intensities were calculated and TED also has been reported.

Vision based AGV (Automatic Guided Vehicle) with RTOS (uC/OS-II) is designed and developed for controlling two wheeled differential servo motor drive. In order to meet the demand of function, reliability, cost and real time performance compared to its commercial counterpart of general purpose computer the system is implemented with RTOS. The multi-processor embedded system with distributed architecture consists of a main-controller of vehicle management based on the ARM LPC2378, and a sub-controller of vision navigation based on the DSP BF533. The embedded RTOS uC/OS-II is used to construct a software development platform, on which different functions needed are described as several tasks, and a number of system services facilitate software realization. In the practical application of device reformation, a commercial AGV product is upgraded by the embedded vehicular controller we develop, on which a sophisticated algorithm of path tracking is implemented successfully and efficiently. The experimental result demonstrates the effectivity and advantages of the embedded multi-processor controller with the RTOS uC/OS-II presented in this paper versus its commercial competitor.

Abdominal elcetrocardiograms make it possible to dertermne the fetal heart rate and to detect multuiple fetuses and are often used during labor and delivery.the background noise due to muscular activity and feotus motion, however, often had an amplitude equal to or grater than that of fetal heartbeat.A still more serious problem is the mother’s heart beat,which has an amplitude 2 to 10 times grater thatn that of the fetal heartbeat, and often interferes in recording[1]. The Maternal ECG (MECG) is the main source of interference in Fetal ECG (FECG) monitoring. The MECG is detected at all electrodes placed on the mother’s skin (thoracic and abdominal). In the case of multi-fetal pregnancies the traditional adaptive filtering technique provides a “maternal clean“ signal consisting of the two fetal ECG signals. The noise was found to be too strong for the algorithm (and the naked eye) to notice any fetal heart signal[1]. This paper briefs the implementation of Adaptive noise cancellation algorithms such as LMS algorithm and RLS algorithm using MATLAB 6 (R12) suitable for real time implementation, which can be used during measurements, is being developed using VLSI. The best solution in case of multiple fetuses is the BSS filtering which has successfully been implemented in MATLAB.

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.
