The Medical Education and Best Practice in Orthopedic Patient Care in Poland[View] pp 1-4
Anna Rosiek, Krzysztof Leksowski

The leadership organization focuses on education, teamwork, customer relationship and developing strategy which help in building added value, in managing activities, time and quality. Everyday orthopedic experience shows that medical education is a mixture of: specific knowledge, skills and attitudes of people working together, and that creates effective teamwork in a hospital environment. Apart from the main reason of medical education, teaching about disease treatment and health problem solving, medical education should also concentrate on human factors and behavioral aspects of patient treatment in hospital. Assessment of an organization and medical education process by cultural and teamwork criteria, offers a powerful new way to think about performance at the frontlines of healthcare and in the future it could be gold standard for assessing the success of an organization, and standards in medical education, not only in orthopedics.

Enokela, O.S and Alada P.O

Investigation of the strength characteristic of soil from alluvial deposit of River Benue in makurdi stabilized with coconut fiber as a stabilizer was carried as local building material for farm structure. Processed coconut fibers were mixed with the soil at four different mix ratios of 1% fiber, 2% fiber, 3% fiber and 4% fiber by percentage weight with 0% fiber as control. Compaction test and compressive strength were carried out on the various stabilizing ratio. From the compaction test, the correlation between the maximum dry density and optimum moisture content is a second order polynomial with a coefficient of 63% obtained at 1.91kg/m3 and 20.0% respectively while the compressive strength test shows an optimum failure load of 8.62N/mm2 at 2%fibre:100% soil mix ratio at 2.16 maximum dry density.

Sam, S. M, Udosen, I. R. and Mensah, S. I.

The proximate, minerals, vitamins and anti-nutrients composition of Solanum verbascifolium Linn were determined. The proximate composition showed that moisture content was (85.5%), protein was (32.55%), lipid was (2.90%), ash was (7.20%), fibre was (4.80%), carbohydrate was (52.55%) and caloric value was (366.50%) respectively. This was found to be rich in protein and considerably high amount of carbohydrate. The anti-nutrient composition analysis revealed the presence of hydrocyanide (1.39mg/100g), Oxalate (114.40mg/100g), all of which are below toxic level except for oxalic acid. For mineral and vitamin compositions, potassium was significantly (P>0.05) higher than iron, sodium, calcium and phosphorus while vitamin A retinol was (371.72mg/100g) and vitamin C ascorbic acid (39.99mg/100g). Based on these findings the plant is recommended for consumption and for further investigation as a potential raw material for pharmaceutical industry.

Dr.A.Sudhakaraiah, E. Gnana Deepika, V. Rama Latha , T.Venkateswarulu

Among the various applications of the theory of Restrained domination, the most often discussed is communication network. There has been persistent in the Algorithmic aspects of interval graphs in past decades spurred much by their numerous application of an interval graphs corresponding to an interval family I. A set is a Restrained dominating set of a graph , if every vertex not in is adjacent to a vertex in and to a vertex in . In graph theory, a connected component of an undirected graph is a subgraph in which any two vertices are connected to each other by paths. For a graph , if the induced subgraph of itself is a connected component then the graph is called connected. A Restrained dominating set RDS of a graph is a Non-split restrained dominating set, if the induced subgraph is connected. In this paper we introduce an Algorithm to find a Non-split Restrained dominating set of an interval graph .

Radiological Evaluation of Ambiguous Genitalia with Various Imaging Modalities [View] pp 31-44
Dr.Ravi N, Dr.BindushreeKadakola

Disorders of sex development (DSDs) are congenital conditions in which the development of chromosomal, gonadal, or anatomic sex is atypical. These can be classified broadly into four categories on the basis of gonadal histologic features: female pseudohermaphroditism (46,XX with two ovaries); male pseudohermaphroditism (46,XY with two testes); true hermaphroditism (ovotesticular DSD) (both ovarian and testicular tissues); and gonadal dysgenesis, either mixed (a testis and a streak gonad) or pure (bilateral streak gonads). Imaging plays an important role in demonstrating the anatomy and associated anomalies. Ultrasonography is the primary modality for demonstrating internal organs and magnetic resonance imaging is used as an adjunct modality to assess for internal gonads and genitalia. Early and appropriate gender assignment is necessary for healthy physical and psychologic development of children with ambiguous genitalia. Gender assignment can be facilitated with a team approach that involves a pediatric endocrinologist, geneticist, urologist, psychiatrist, social worker, neonatologist, nurse, and radiologist, allowing timely diagnosis and proper management. We describe case series on ambiguous genitalia presented to our department who were evaluated with multiple imaging modalities.

Dr. Lora Mishra, Dr. Manoj Kumar, Dr. C.V. Subba Rao

Aim: To assess Calcium loss from root canal dentin following EDTA and Tetracycline - HCL Treatment with or without subsequent NaOCl Irrigation and evaluation of microhardness of dentin. Materials and methods: Sixty freshly extracted single rooted premolars were selected.The teeth were sectioned longitudinally into two equal halves along the long axis using Diamond disc. The one half of the specimen is used for the Calcium loss evaluation by ICP-AES technique and the other one half with the acrylic block is used for the micro hardness study. The data was analysed using One - way ANOVA and Post Hoc Tuckey test. Results: The maximum calcium loss was observed in Group V 17% EDTA +2.5% NaOCl (3.88 ± 0.30), followed by Group III 17% EDTA (3.46 ± 0.43 mg/L), Group VI 1% Tetracycline HCl + 2.5% NaOCl (1.71 ±0.28mg/L), Group IV Tetracycline HCl (1.46 ± 0.29mg/L). Group I distilled water (0.17± 0.25mg/L) and Group II 2.5% NaOCl (0.28± 0.05mg/L) had the least calcium loss value with p < 0.001. Dentin Microhardness in Group I (67.6 ± 1.70 VHN), Group II (65.5 ± 3.57 VHN) Group IV and in Group VI (61.5± 1.09) showed significantly higher when compared to the mean values in Group III (59.7 ± 4.3mg/L) and in Group V (55.2±2.53VHN) withp<0.001. Conclusion: Group V 17% EDTA + 2.5% NaOCl resulted in maximum Calcium loss, but has reduced the microhardness. But Group VI 1%Tetracycline HCl + 2.5% NaOCl solution effectively removed Calcium without much altering the microhardness of the root dentin.

Soft Starting Arrangements Availables For Hot Rolling Mills For Energy Conservation[View] pp 51-65
A.M.Bisen, Dr. P.M. Bapat And Dr. S.K. Ganguly

The conventional rolling mills in India are producing a major part of structural steel requirement of the country. The energy conservation in these rolling mills can be achieved mainly by reducing the size of the prime mover i.e. main electric motor. The power consumption per ton can be considerably decreased through proper selection of electric motor since it has been an observation by many surveyors[1] that the selection of electric motor of the rolling mill has been almost five to ten times on the higher side which can be easily verified from the power consumption and motor working data.

Studies on Bee Venom and Its Medical Uses[View] pp 69-83
Mahmoud Abdu Al-Samie Mohamed Ali

Use of honey and other bee products in human treatments traced back thousands of years and healing properties are included in many religious texts including the Veda, Bible and Quran. Apitherapy is the use of honey bee products for medical purposes, this include bee venom, raw honey, royal jelly, pollen, propolis, and beeswax. Whereas bee venom therapy is the use of live bee stings (or injectable venom) to treat various diseases such as arthritis, rheumatoid arthritis, multiple sclerosis (MS), lupus, sciatica, low back pain, and tennis elbow to name a few. It refers to any use of venom to assist the body in healing itself. Bee venom contains at least 18 pharmacologically active components including various enzymes, peptides and amines. Sulfur is believed to be the main element in inducing the release of cortisol from the adrenal glands and in protecting the body from infections. Contact with bee venom produces a complex cascade of reactions in the human body. The bee venom is safe for human treatments, the median lethal dose (LD50) for an adult human is 2.8 mg of venom per kg of body weight, i.e. a person weighing 60 kg has a 50% chance of surviving injections totaling 168 mg of bee venom. Assuming each bee injects all its venom and no stings are quickly removed at a maximum of 0.3 mg venom per sting, 560 stings could well be lethal for such a person. For a child weighing 10 kg, as little as 93.33 stings could be fatal. However, most human deaths result from one or few bee stings due to allergic reactions, heart failure or suffocation from swelling around the neck or the mouth. As compare with other human diseases, accidents and other unusual cases, the bee venom is very safe for human treatments.

Swati A. Barbade, Prabha. Kasliwal

To complement the other types of pollution-free generation wind energy is a viable option. Previously wind turbines were operated at constant speed. The evolution of technology related to wind systems industry leaded to the development of a generation of variable speed wind turbines that present many advantages compared to the fixed speed wind turbines. In this paper the phasor model of DFIG is used. This paper presents a study of a doubly fed induction generator driven by a wind turbine connected to the grid, and controlled by artificial neural network ANN controller. The behaviour of the system is shown with PI control, and then as controlled by ANN. The effectiveness of the artificial neural network controller is compared to that of a PI controller. The SIMULINK/MATLAB simulation for Doubly Fed Induction Generator and corresponding results and waveforms are displayed.

Changes In Germinability And Activities of Polyphenol Oxidase And Peroxidasein Seeds of Pentaclethramacrophylla During Low Temperature Treatment[View] pp 89-98
Udosen, I. R., Nkang, A. E. and Sam, S. M

Activities of peroxidase (POD) and polyphenol Oxidase (PPO) were investigated in seeds of Pentaclethramacrophylla during low temperature treatment. The seeds from the small-sized fruits (variety A) and those of the big-sized fruits (variety B) showed high germination, with maximum germination values ranging between 60 - 90%. Low temperature treatment did not significantly (P< 0.5) affect maximum germination values. Activities of POD and PPO increased initially (2-4 days) but declined with prolonged (6-8 days) low temperature treatment.

Simar Buttar

With the advance of wireless communications, the problem of bandwidth scarcity has become more prominent. Cognitive radio technology has come out as a way to solve this problem by allowing the unlicensed users to use the licensed bands opportunistically. To sense the existence of licensed users, many spectrum sensing techniques have been devised. In this paper, energy detection and cyclic prefix is used for spectrum sensing.The comparison of ROC curves has been done for various wireless fading channels using squaring and cubing operation,the improvement has gone as high as up to 0.6 times for AWGN channel and 0.4 times for Rayleigh channel as we go from squaring to cubing operation in an energy detector. Closed form expressions for Probability of detection for AWGN and Rayleigh channels are described.Nakagami fading channel shows worst results .

CFD Simulation of SDHW Storage Tank with and Without Heater[View] pp 124-134
Mr. Mainak Bhaumik

2D-Single Phase heat and fluid flow analysis of solar domestic hot water (SDHW) storage tank has been carried out by using CFD tools, ICEM for modelling & meshing and FLUENT for analysis. The tank fluid is in static mode. Heat diffusion and convective heat loss from the tank without heater and with the involvement of additional heater is studied. After heating water gets lighter and moves upward in the tank and cold denser water remains at the bottom of the tank. The movement of the water particles are also analysed to find the effect on heat transfer and heat loss. Time transient analysis is focused on for a constant fixed temperature of water inside the tank and the heat drop is captured. Investigation gives guidelines how long the water temperature can be maintain warmer within the tank while the tank is uninsulated. If it is required to maintain temperature constant then the involvement of heater can be useful in what extend.

Swine Flu -A Comprehensive View[View] pp 135-139
Vandana Singh and Dr. Meenakshi Sood

The present article is aimed on comprehensive view of Swine flu. It was first isolated from pigs in 1930 in USA. Pandemic caused by H1N1 in 2009 brought it in limelight. It's a viral respiratory disease caused by viruses that infects pigs, resulting in nasal secretions, barking cough, decreased appetite, and listless behavior. Swine virus consist of eight RNA strands, one strand derived from human flu strains, two from avian (bird) strains, and five from swine strains. Swine flu spreads from infected person to healthy person by inhalation or ingestion of droplets contaminated with virus while sneezing or coughing. Two antiviral agents have been reported to help prevent or reduce the effects of swine flu, flu shot and nasal spray. WHO recommended for pandemic period to prevent its future outbreaks through vaccines or non-vaccines means. Antiviral drugs effective against this virus are Tamiflu and Relenza. Rapid antigen testing (RIDT), DFA testing, viral culture, and molecular testing (RT-PCR) are used for its diagnosis in laboratory.

Flood Vulnerability Analysis of the part of Karad Region, Satara District, Maharashtra using Remote Sensing and Geographic Information System technique[View] pp 140-146
Sumedh R. Warghat, Sandipan Das, Atul Doad, Sagar Mali

Karad City is situated on the bank of confluence of river Krishna & Koyana, which is severely flood prone area. The floodwaters enter the city through the roads and disrupt the infrastructure in the whole city. Furthermore, due to negligence of the authorities and unplanned growth of the city, the people living in the city have harnessed the natural flow of water by constructing unnecessary embankments in the river Koyna. Due to this reason now river koyna is flowing in the form of a narrow channel, which very easily over-flows during very minor flooding.

Injection circuit to the HV GRID using Adaptive Fuzzy Dividing Frequency-Control Method[View] pp 147-156
Mr.Bodha venugopal Reddy, Mr.N.Narender Reddy, Dr.A.Srujana

This paper deals with a hybrid active power filter with injection circuit (IHAPF). It exhibits clear promise in decreasing harmonics and increasing the power factor with a comparatively low capacity active power filter. This paper concludes that the stability of the IHAPF based on spotting supply current is exceptional to that of others. To minimize the capacity of IHAPF, an adaptive fuzzy dividing frequency control method is used, which consists of two control units: a generalized integrator control unit and fuzzy adjustor unit. The generalized integrator is used for dividing the frequency integral control, while fuzzy arithmetic is used for adjusting proportional-integral coefficients timely. And the control method is generally useful and applicable to any other active filters. Compared to other IHAPF control methods, the adaptive fuzzy dividing frequency control shows the advantages of shorter response time and higher control precision. It is implemented in an IHAPF with a 100-k VA APF installed in a copper mill in Northern China. The simulation and experimental results show that the new control method is not only easy to be calculated and implemented, but also very effective in reducing harmonics.

Analytical Study of different types Of network failure detection and possible remedies[View] pp 157-161
Shikha Saxena, Somnath Chandra

Faults in a network have various causes,such as the failure of one or more routers, fiber-cuts, failure of physical elements at the optical layer, or extraneous causes like power outages. These faults are usually detected as failures of a set of dependent logical entities and the links affected by the failed components. A reliable control plane plays a crucial role in creating high-level services in the next-generation transport network based on the Generalized Multiprotocol Label Switching (GMPLS) or Automatically Switched Optical Networks (ASON) model. In this paper, approaches to control-plane survivability, based on protection and restoration mechanisms, are examined. Procedures for the control plane state recovery are also discussed, including link and node failure recovery and the concepts of monitoring paths (MPs) and monitoring cycles (MCs) for unique localization of shared risk linked group (SRLG) failures in all-optical networks. An SRLG failure is a failure of multiple links due to a failure of a common resource. MCs (MPs) start and end at same (distinct) monitoring location(s). They are constructed such that any SRLG failure results in the failure of a unique combination of paths and cycles. We derive necessary and sufficient conditions on the set of MCs and MPs needed for localizing an SRLG failure in an arbitrary graph. Procedure of Protection and Restoration of the SRLG failure by backup re-provisioning algorithm have also been discussed.

Transient Stability Improvement Of Multi-machine Power System Using Fuzzy Controlled Tcsc[View] pp 162-172

Power system is subjected to sudden changes in load levels. Stability is an important concept which determines the stable operation of power system. In general rotor angle stability is taken as index, but the concept of transient stability, which is the function of operating condition and disturbances deals with the ability of the system to remain intact after being subjected to abnormal deviations. A system is said to be synchronously stable (i.e., retain synchronism) for a given fault if the system variables settle down to some steady-state values with time, after the fault is removed.

Post Buckling Behaviour of a Nanobeam considering both the sur-face and nonlocal effects[View] pp 173-177
Rajarshi Maitra,Supratik Bose

Nano-scale beams and plates have been the key components of the sensor and actuator in nanoelectromechnical (NEMS) systems with wide applications in environmental monitoring, medical diagnostics, food processing, mining, bioengineering and defence. Nonlocal and surface effects have been incorporated to find critical load of a nano beam subjected to a transverse loading. The Nonlocal theory, expresses the stress field at a point in an elastic continuum in terms of not only strains at that point but also the strains throughout the body. The governing equation of a normal beam has been modified to achieve the governing differential equation of a nano beam. The post buckling behaviour of a nano beam has been tried to be assessed. The results showed that the surface effects try to delay the buckling process whereas the nonlocal effects contribute to the instability.
