Association of Diabetic Neuropathy and Low Serum Calcium Levels in Diabetic Patients[Full-Text ] Suresh Kumar P, T. Ramakrishna, E. SreekumaranDisturbances in Calcium (Ca2+) and phosphorus metabolism were observed in uncomplicated type 1 Diabetes Mellitus and type 2 Diabetes Mellitus patients. Hormones like PTH, calcitonin etc are involved in it. There is a growing body of evidence that sensory neuropathy in diabetes is associated with abnormal calcium signaling in dorsal root ganglion neurons. Abnormal calcium signaling in diabetes has pathologic significance as elevation of calcium influx and cytosolic calcium release has been implicated in other neurodegenerative conditions characterized by neuronal dysfunction and death. Serum Ca2+ levels were assessed and found that 53.1 % males and 46.9 % females, whose calcium was analyzed, are having low serum Ca2+ values. Mean serum calcium values of hyper-insulinemic patients was 8.06 mg%. Males had lower values in both hyper insulinemic (7.94 mg% for male vs 8.26 mg% for female) as well as low insulin groups (8.2 mg% for male vs 8.8 mg% for female). It is essential that we have to look beyond blood sugar and lipids, and that it may be important to assess serum calcium and other relevant micro and macro nutrients levels and to correct any deficiency by supplementing the same.

A review of Homogeneous charge compression ignition (HCCI) engine[Full-Text ] Gowthaman S,Sathiyagnanam A.P Homogeneous charge compression ignition (HCCI) engine uses a relatively new mode of combustion technology. In principle, there is no spark plug or injector to assist the combustion process, and the combustion starts at multiple spots once the mixture has reached its auto ignition temperature. The challenges over the operation of HCCI mode engines are the difficulties of controlling the auto-ignition of the mixture, operating range, homogeneous charge preparation, cold start, controlling knock and emissions of unburned hydro carbon (UHC) and carbon monoxide (CO), and need to be overcome these difficulties for achieve successful operation of HCCI mode engine. This paper reviews the implementation of HCCI combustion in direct injection diesel engines using early, multiple and late injection strategies and reviews the different strategies of Homogeneous mixture preparation by external (manifold injection) and in-cylinder mixture preparation methods. Although this review focus on governing factors in HCCI operations such as injector characteristics, injection pressure, piston bowl geometry, compression ratio, intake charge temperature and exhaust gas recirculation (EGR) are discussed in this review. And also review the effects of design, combustion control technique and operating parameters on HCCI mode engine emissions, particularly NOx and soot are investigated. For each of these parameters, the theories are discussed in conjunction with comparative evaluation of studies reported in the specialised literature. Form this study we will be concluded that the efficient method of homogeneous mixture preparation and will be identified the parameter to achieve the combustion in HCCI mode engine.

BEHAVIORAL DEFICITS IN WISTAR RATS SECONDARY TO ALTERED ANDROGEN LEVELS AFTER TREATMENT WITH CHICKEN FEED AND RAW SOYBEAN[Full-Text ] Saara Ahmad, Iftikhar AhmedChicken meat is the most favorite consumable commodity current days. The eminent demand for the chicken meat is satisfied through the poultry farms operational day and night feeding the chicken feed as a chief basis for the untimely growth and weight growth of the chickens. The aim of the present study was to investigate the consequences of the commercially available chicken feed and raw spinach on mood alteration in rats. Seventy five female albino wistar rats were used in the experiment. Animals were randomly allocated to three groups (n=25), control rats fed on standard rodent chow, chicken feed treated rats and raw soybean treated rats for a period of 6 weeks. Serum androgens levels were estimated before and after the treatment. After 6 weeks behavioral alterations like lateral attacks, biting and muricidal behavior was monitored in rats. Components of chicken feed were analyzed through Pakistan council of scientific and industrial research (PCSIR) laboratories. The present study showed that the behavioral deficits and serum androgen levels of the feed treated group rose significantly as compared to control group and spinach treated group. It was as a result, concluded that the chicken feed treated rats showed increased serum androgen levels with increase in lateral attacks, biting and muricidal behavior. The finding maybe suggested that the potential alterations in mood and behavior are due to chicken feed additives of animal by products that may lead to increase androgen levels in chickens. This finding may be of relevance to the dietary inclination of population more towards chicken products which may lead to alteration in androgen levels and behavioral changes.

Neem fruits were collected from a plantation. Ripe fruits were sorted and neem seeds were obtained by manually depulping the ripe fruits, washed and sundried to about 5.10 % (wb) moisture content. Moisture content adjustment by rewetting was carried out to obtain three levels of 9.95, 14.17 and 18.69 % (wb). Physical properties (length, width, thickness, geometric mean diameter, sphericity, aspect ratio, volume, surface area, 1000-seed mass, true density, bulk density, density ratio and percentage porosity) of the dried seeds and the embedded kernels were determined. Data obtained were statistically analyzed to obtain the descriptive and inferential statistics. Results showed that the seed ranges in values for length (14.15 to 14.51 mm), volume (4.55 to 4.57 mm3), surface area (238.2 to 240.1 mm2), 1000-unit mass (216.2 to 326.9 kg), true density (555.8 to 594.3 kg/m3), bulk density (354.19 to 375.12 kg/m3), density ratio (156.95 to 158.40), while the width reduced from 6.97 to 6.94 mm, thickness 6.7 to 6.6 mm, aspect ratio 49.4 to 47.9, percentage porosity 36.15 to 36.04. Similarly, for the kernel, the length ranged from 11.02 to 11.27 mm, 1000-unit mass 336.0 to 347.4 kg, true density 797.1 to 954.3 kg/m3, density ratio 139.70 to 182.18, percentage porosity 28.29 to 45.02. Likewise, the width decreased from 4.49 to 4.42 mm, thickness 4.2 to 3.9 mm, geometric mean diameter 5.9 to 5.8 mm, sphericity 0.54 to 0.52, aspect ratio 40.9 to 39.4, volume 3.08 to 3.03 mm3, surface area 109.2 to 105.4 mm2 and bulk density 571.4 to 523.6 kg/m3 as moisture increased. However, seed geometric mean diameter (8.7mm) and sphericity (0.6) remained constant. For many of the properties considered, moisture content significance at (p<0.05) but was not uniform on both seeds and kernel.

A Comparison Between Lean Implementation and Critical Chain Management [Full-Text ] Muhammad AlEnzyLean is managed by visual controls that warn and reflect the performance of any process in a firm and the value that is making. Visual controls that can help decision makers or even improvement seekers; to optimize their decisions based on real inputs from those controls and measures which are supposed to be managed with discipline and precision to lead to the targeted “lean” culture and what makes the culture cultivating throughout the process of getting lean is the “reward system” that is complementing the lean culture to sustain the cycle of improvement. However, many tools have been generated from lean systems as a continuous improvement for the lean itself by many experts and scientists. However, one of those outcome tools is the Theory of Constraints (TOC). TOC is enclosing the common idiom "A chain is no stronger than its weakest link" as a new management paradigm. This means that TOC is always looks at the weakest ling in the chain, and by extract the max out of that constraint to improve the delivery of that chain. However, TOC has been developing over years and producing some operations management initiatives such as the Critical Chain Project Management (CCPM).

Treatment of Industrial Wastewater in Sand-based Surface flow Constructed wetland using Typha Orientalis as Macrophyte[Full-Text ] Oladejo Oladipupo. S., Oladiran Bolaji J, Dauda Idris, Oyewale David M, Fasina Tomisin J.A laboratory-scale free water surface-flow constructed wetland was set up at the Department of Civil Engineering, Ladoke Akintola University of Technology (LAUTECH) Ogbomoso, Nigeria in May 2013 to demonstrate the performance of sand- based constructed wetland, using Typha Orientalis as a viable low-cost efficient treatment option for Industrial wastewater from Pharmaceutical Company. The nutrient removal and performance evaluation of the constructed wetland in treatment of kitchen wastewater against retention period of ten days was investigated. During the 10-day retention period, the sand- based constructed wetland set up with Typha Orientalis had improved the wastewater quality significantly as it had reduced the concentrations of BOD5, Nitrate, Sulfite, Magnesium, Turbidity and Oxygen Reduction Potential (ORP) by 46.96%, 50%, 63.63%, 42.96%, 31.03%, 63.63%, respectively on the average, respectively and the initial offensive odour of the raw water was no more noticeable. The final effluent was found to be suitable for non-drinking purposes like crop irrigation and keeping aquatic animals. However, it was noted that a 7- day detention time was optimal for the treatment of domestic wastewater from kitchen. The treatment system was found to be economical, as the cost of construction only was involved and maintenance cost very minimal. It was environmentally friendly as it was free from offensive odour and insect invasion. The prototype scale is recommended for in-situ use, especially for wastewater from kitchen.

APPLICATION OF ARTIFICIAL NEURAL NETWORKS (ANNs) IN REACTIVE POWER OPTIMIZATION[Full-Text ] Kamel A. ShoushThe reactive power optimization problem is one of the most important problems facing dispatching engineers when they are operating large scale power systems. Reactive power optimization is mathematical approach of the power system optimization problem which is to determine the least control movements to keep power system at a most desired state. It is very flexible and powerful tool which can address a wide range of planning and operation circumstances. However the complexity of reactive power optimization often discourages the user. This paper proposes a new artificial neural network-based approach (ANN) for reactive power optimization of interconnected power systems. Feed-forward ANN with Back Propagation (BP) training algorithm is used and the training data is obtained by solving several abnormal conditions using Linear Programming (LP). Considering generator voltages, reactive power sources and transformer taps as control variables, and load bus voltages and generator reactive powers as dependent variables. The relations are derived according to sensitivity relations based on Newton-Raphson load flow equations. The 220 kV network of the Unified Power System of Egypt (UPSE) was used in this paper to test the suggested approach.

A Novel Approach to the Methods for Fostering the Champions in Sport: A New Study and Investigation[Full-Text ] Mostafa KhonsariEach athlete can become a champion if he/she try but, certainly, each champion cannot become a coach. Coaching is a very complicated work. In addition to dominating the technical skills of the considered sport, a coach should be known about how is the teaching method of those skills. Further, a coach should be a psychologist, mentor, and a moral standard for athletes. As it is clearly demonstrated that the behavioral influence of coaches on social character of athletes is inevitable, the personal beliefs of coach and his/her character, behavior and act are played a basic role in this issue. Since the role of coach is not, only, upbringing of champion and a coach is responsible for developing the public sport and character of athletes; he/she needs to a comprehensive program. Usually, coaches have not been a program, firstly, to follow coaching. Coaching is an inherent issue. An educated person will not be necessarily a paramount coach.

Moses in Islamic and Jewish Theosophical Traditions: With Emphasis on Fusus Al-Hikam by Ibn Arabi and Zohar by Moses de Leon[Full-Text ] Masood Ahmadi AfzadiMoses is a great messenger of Abrahamic (or Semitic) religions, especially, Islam and Judaism. Moses has a special stall in holy texts of both religions. Moses, his prophecy and the Israelites (Bani Isra’il) have mentioned, in a particular manner, in exodus, the second book of the Old Testament, and also is various suras of Quran and interpretations related to these holy texts. This reminiscence is not limited to prophetic texts and has a considerable spread in theosophical contexts. Fusus Al-Hikam, by Ibn Arabi, as one of the greatest references of theoretical theosophy in Islam, and Zohar, by Moses de Leon, as the greatest text of Kabbalah, which both have been published, simultaneously, in Andalusia (Spain), are of special attention to Moses. The current research compares the features of Moses in these two theosophical traditions.

Survey on Algorithms for Data Compression in Wireless Computing Systems[Full-Text ] Upasana Mahajan, Dr. Prashanth C.S.RData compression is a technique in which the same amount of data is transmitted by using a smaller number of bits with the help of an algorithm. Different compression algorithms are compared and based on their performance the optimal algorithm is selected. In this paper the different data compression algorithms have been selected and their performance evaluation is done. One of the best and easy algorithms is Huffman’s Encoding but the result of evaluation of performance shows that the Huffman’s algorithm has some drawbacks, and can be overcome by new algorithm named as Selective Huffman’s algorithm. The paper focus on a new technique for compression named as semi-lossless text compression, which states that instead of compressing the whole data if only some portion of the data is compressed the time and space can be saved. The paper also attempted to explore each layer and shows what are different compression techniques can be used in TCP/IP model.

Image Steganography using Non Embedding and Average Technique in Transform Domain[Full-Text ] N Sathisha, K Suresh Babu, K B Raja, K R VenugopalThe steganography is an art and science of hiding information into a given media to ensurethe security of information over the communication channel. In this paper we propose a Image Steganography using Average Technique in Transform Domain (ISATT). The Lifting Wavelet Transform (LWT) is applied on both cover image and payload. The Diagonal band (CD) of cover image and Approximation band (PA) of payload are segmented into N x N blocks. The N x N matrix of PA is divided by N x N matrix of CD to generate resultant matrix based on Non Embedding Threshold Value (NETV) fixed by key. The average value of N x N resultant matrix is calculated and used to divide PA to generate modified CD. The average value of each N x N block are scale downed by key and embedded into corresponding N x N block of horizontal band (CH) of cover image. The inverse LWT is applied on stego object to derive stego image1. The Peak Signal to Noise Ratio (PSNR) is computed between cover image and stego image1 for different NETV values till maximum PSNR is obtained and the corresponding stego image is considered as final stego image. The capacity and PSNR values are high in the case of proposed algorithm compared to existing algorithms since non embedding and average technique is used in transform domain.
