This study aimed to assess the growth pattern of adolescent boys in Mysore city in south India. In this cross sectional study anthropometric profile of 1083 boys aged 10- 18years was measured and compared to 50th centiles of W.H.O standards for height and weight and the measurement of MUAC and SFT were compared to NHANES standard. Self-reporting questionnaire to obtain data related to family socioeconomic status and personal information was implemented. The increase in height exhibited linearity from 10 to 18 years of age, mean height was 141.8?1.56 cms in boys aged 10years while boys aged 18 year had a mean height of 172.2± 7.15 cms The mean weight at age 10 was 31.7± 3.10 kgs and at 18 years the mean body weight was 58.6± 9.04 kg. In this study population the mean BMI was15.63±2.21 at the age 10 and increased to 19.71 ± 2.42 at age 18th year The mean MUAC at the age 10 was 19.6±1.72 cm and skin fold at triceps was 11.07±3.5 mm. These participate boys were shorter and lighter in all the stages of adolescences as compared to reference, although the difference for height was smaller than that seen for weight. BMI, of boys in all age groups was lower as compare to the W.H.O references.

This work proposes a methodology for QoS improvement in MANET based on Medium Access Control (MAC) protocol that takes the above requirements into consideration. This protocol is based on IEEE 802.11 standard, and thus can be easily integrated into existing systems without much difficulty. Here 802.11 and 802.11e with different TCP mechanisms are used to analyze the QoS parameters for MANETs. The proposed system is designed to evaluate the performance of QoS and interaction between Transport layer and the MAC layer protocol operating in a mobile ad hoc network. The system will makes use of IEEE 802.11e MAC mechanism, to improve quality of service in MAC layer, which will improve the quality of service in Transport layer and to suggest a suitable mechanism for improving the quality of service in MANETs.

The soils derived from charnockite in Ekiti State Nigeria were found to be low in zinc and phosphorus. This study was therefore conducted during the rainy seasons of 2006 and 2007 to evaluate growth and yield response of soybean TGX-1440LE from the direct effect and interaction of phosphorus and zinc. Treatments consisted of factorial combination of two levels of P(0,and 30kgPha-1), three levels of Zn(0,2,and 4kg Zns04ha-1) in a randomized complete block design in a soil developed in charnockite in Ekiti State The growth data were collected at 2 weekly intervals while yield components were taken at harvest. Stem girth, number of nodules and nodule weight significantly (P < 0.05) increased with 2kg Zn ha-1 application, which gave 111.2% yield advantage over the control treatment (0kgZn ha-1). Fertilizer rate above 2kgZn ha-1 significantly (p<0.05) decreased P uptake. The 30kgP ha-1 rate produced better growth, which was not significantly different from 0 kgP ha-1 while increase in P and Zn uptake was significant. The P x Zn interaction was significant for grain yield and Zn uptake. The treatment combination that gave the highest yield was 30kgP ha-1 and 2kgZn ha-1.

Harihara is a poet's unique and immense contribution to Kannada literature. He is a representative of the age by depicting all aspects of contemporary life in his works. From Vipra to Anthijana, from the laborer to the king, from the girl to the widow, everyone takes the place of heroes in his works. Basavanna's devotional spirit and Harihara's devotional ecstasy can be felt mutually. This concept of devotion is the embodiment of Basavanna's personality for Harihara. The most attractive and impressive aspect is that Harihara, who paints Basavanna down to the core, reveals the layers of his devotion as if full of poetry.

Effect of pressure on the ground state exciton binding energy and the interband emission energy in a wurtzite GaN quantum dot are investigated. The interband emission energy is computed as a function of pressure with a constant geometrical confinement. All the numerical calculations are performed using variational procedure within the single band effective mass approximation. The internal electric fields comprise the spontaneous polarization and piezo electric polarization are included in the Hamiltonian. Our results show that the effects of pressure and the geometrical confinement have great influence on the optical properties of this wide band gap nitride based group-III quantum dots.

Ready-to-eat breakfast cereal (RBC) containing underutilized legume was made to improve its nutrient and reduce cost. Blends of yellow maize (Zea mays) and African yam bean (AYB) (Sphenostylis stenocarpa) at 100:0, 90:10, 80:20, and 70:30 were used to produce RBC using locally adaptable process. Products were analyzed for proximate, anti-nutritional and mineral contents, as well as sensory test. Highest protein content of 15.98% was obtained in 70:30 AYB supplemented sample. There was no significant (p<0.05) difference in gross energy of the samples which were liked by the panelists. Low technology for producing RBC could improve food security among the poor.

This study was aimed at determining the uptake of heavy metals (Cd, Pb, Ni, Fe and Zn) by plant (Talinum triangulare) if cultivated at some waste dumpsites in Uyo metropolis. Soil samples were taken within 0-15cm and plant samples were collected in triplicate and analysed using Atomic Absorption Spectrophotometer (AAS). Mean results obtained from the soil and plant samples indicated Fe to have the highest concentration (216.29±29.15mg/kg and 243.339±12.622mg/kg respectively) which is significantly higher than its control (124.00mg/kg and 78.375mg/kg respectively). Concentration of Pb in both dumpsite soil and plant samples were below detectable limit. These results when compared with the acceptable standard revealed that all the metal levels in both soil and plant samples were within the acceptable limits accept Cd in soil sample. Transfer factor for Fe was 1.13, while others were below 1. All the metals showed positive relationship except Cd (-0.60).

This research was carried out in Keta Municipality of Volta Region of Ghana to investigate how resources are used in the production of chili pepper. A simple random technique was used to select 100 chili pepper farmers from three communities in Woe, Keta Municipality. The data was collected from December 2010 to January 2011. The Cobb-Douglas production function was used to determine the resource use efficiency of inputs used by the farmers. The findings of the study showed that the farmers were operating in stage two of the production frontier. This was shown from the elasticities of the various inputs, showing diminishing return which is a characteristic of the stage two of the production function. However, the farmers were found not to be efficient in allocating the resources for production in the study area. The ratio of the marginal value product (MVP) and the marginal factor cost (MFC) was found to be less than unity for all the inputs except labour and organic manure. The study recommends that the farmers should reduce the level of those inputs that are being over used. They should rather increase the use of organic manure and maintain the quantity of labour use.

Cryonics-raising the dead: The concept goes like this: When a patient’s heart stops beating, but before the structure of his brain starts to degenerate, the patient is attached to a heart –lung machine and progressively infused with ‘antifreeze’ and other cellular stabilizers and then his body temperature is lowered until the patient is at ‘liquid nitrogen temperatures’. At this point, all molecular change stops indefinitely and the patient are put in storage. When the nanotechnology cell repair devices become available, the fatal disease that caused ‘death is reversed, the anti-freeze toxicity is removed, and the patient is warmed back up alive and well. In cryonics- freezing people fore future – scientists take patients who have been labeled as ‘dead’ by current medical criteria, replace their blood and much of their body water with chemicals to inhibit freezing damage, and preserve them in liquid nitrogen at (-196 Celsius). At that temperature all molecules in the body are locked in solids can no longer move around to react. Thus the individual can remain unchanged for thousands of years. It is possible that frozen patients will repairable and relabeled as ‘potentially alive’ by using nannies

As organizations become aware of the strategic importance of e-commerce they will also become aware of the need of quality Web sites. In early years the World Wide Web was originally designed to present information to Web surfers using simple sites that consists of hyper linked text. But, Modern Web applications run large-scale software applications for e-commerce, information distribution, entertainment, and numerous other activities. The factors that constitute software quality in traditional data processing are well defined. However, it is necessary to have a full understanding about the quality in the context of World Wide Web. This paper identifies a new quality factor, searchability for the World Wide Web with the checklist of enablers. This factor enables the Web site developers and evaluators to create quality Web sites.
