The nutrient and anti- nutrient compositions of the raw and cooked species of Cucurbita maxima fruit consumed in the eastern part of Nigeria were determined. The proximate compositions of the fruit samples showed that the fruit was high in moisture (87.1±0.38%) but low in protein (1.87±0.1%), fat (0.8±0.62%) and carbohydrate (3.96±0.17%). The low fat and protein contents appear to be a common feature of the fruits of the Cucurbitacae family. The fruit of C. maxima sample was found to be poor in the mineral elements. However, it had higher values of magnesium, calcium and phosphorus but very low values of potassium and sodium. The compositions of the mineral elements were also reduced after boiling. The fruit sample had low values of vitamins A (42.39±1.05 mg/100g), E (14.25±0.18 mg/100g) and C (25.67±1.27 mg/100g). Vitamins A and E were not significantly affected by boiling. The fruit sample was found to be rich in some phytochemicals with established medicinal values as well as some anti-nutrients (tannins, HCN and oxalates). However, boiling which is a normal food preparation technique was found to be able to reduce these anti-nutrients to safe levels.

Today, multi-stage compressors serve in many industry branches. The multi-stage compressor design is primarily focused on storage or process conditions. Outside of the guaranteed time that the compressor manufacturer ensures, material fatigue and other mechanical problems that occur during process cause off-design operation of compressors. In this study, the relative Mach number in the discharge and inducer, including the non-dimensional mass flow rate are studied and compared with appropriate available theory.

Produced water represents more than 80% of the volume of waste generated by activities in the oil and gas industry. This is an enormous waste and should be handled and disposed of in a manner that should avoid negative environmental consequences. This paper details laboratory analysis for the removal of some of the harmful chemical and physical properties. Produced water was collected from A-field in the Niger Delta using 250 ml sterile sample bottle. At the end of the analysis, results show that removal of these harmful properties is dependent on the type of treatment proffer as the individual properties have different characteristics of the produced water quality and its origin. Compounds such as aliphatic and aromatic hydrocarbons, polycyclic aromatic hydrocarbon, phenols, and other chemical product which are used to facilitate petroleum production recovery contribute to oilfield water pollution.

This article makes comprehensive literature review and analysis on various scientific experiments and research about the role of age in foreign language learning. Additionally the introduction and analysis of “Critical Period Hypothesis” and its relevant research in second language acquisition has been presented in order to put forward some scientific implications for foreign language learning and instruciton in the context of China.

Now a day’s Security is the main thing. In this paper we focus on distance measures applied to ensure the security of the separate sensitive information. Protecting data security is an key issue in data distribution. Security maintains system in data mining using distance measure techniques typically aim to protect separate security, with minimal impact on the quality of the released data. Now a days, a few of models are proposed to ensure the security protecting and/or to reduce the information loss as much as possible. i.e., they further improve the flexibility of the anonymous strategy to make it more closeness to reality, and then to meet the diverse needs of the people. Different proposals and algorithms have been designed for them at the same time. In this scenario we provide a survey of distance measure techniques for security preserving. We discuss the distance measure methods, the major achievement ways and the strategies of distance measure algorithms, and summarize their advantage and disadvantage. Then we give a demonstration of the work finished. Finally conclude further research directions of distance measure techniques by analyzing the existing work.

Traumatic hip dislocation in children is a rare disease .We report the case of a child aged 11 years old male who presented a posterior pure dislocation of the left hip after a sports accident. A reduction in emergency was performed with a perfect radiological control. Subsequent treatment consisted of pulling stuck for 45 days. The child was seen with a decline of 1 year. Hip was considered normal. This entity is exceptional in small children It may be secondary to minimal trauma as coxa valga or excessive femoral neck anteversion or ligamentous laxity may explain a predisposition to this dislocation. His prognosis is very good if urgent care is performed.

An Ad-hoc network is a collection of mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administer. Because of limited communication range among mobile nodes in ad-hoc network, several network hopes may be needed to deliver a packet from one node to another node in the wireless network. In such a network each node acts as an end system as well as a relay node (or router). Most of the routing algorithms designed for MANET such as AODV and DSR are based on the assumption that every node forwards every packet. But in practice some of the nodes may act as the selfish nodes. These nodes use the network and its services but they do not cooperate with other nodes. Such selfish nodes do not consume any energy such as CPU power, battery and also bandwidth for retransmitting the data of other nodes and they reserve them only for themselves. The original AODV and DSR routing algorithms can be modified to detect such selfish nodes. In this paper, we survey innovated techniques as well as proposed techniques to detect Selfish Nodes for MANET. Finally we provide some directions for further research.

Tablet is defined as solid pharmaceutical dosage form containing drug substance generally with suitable diluents and prepared by either compression or molding methods. Tablets remain popular as a dosage form because of the advantages afforded, both to the manufacturer (e.g. simplicity and economy of the preparation, stability, and convenience in packing, shipping and dispensing) and the patient. Because of their composition, method of manufacture or intended use, tablets present a variety of characteristics and consequently there are several categories of tablets. Tablet formulation and design may be described as the process where by the formulator ensures that the correct amount of the drug in the right form is delivered at or over the proper time at the proper rate and in the desired location, while having its chemical integrity protected to that point. Latest concepts and regulations focus on bioavailability, bioequivalence and validation etc. impact formulation designing and manufacture.
