Energy as electromagnetic waves has primary and secondary effects. Certain shapes have affect the secondary effect either positively or negatively. BioGeometry is dealing with shapes which affect positively on energy. BioGeometry has principles of designs which used during design shapes. Fashion designs also have elements and principles which used during clothing designs. The human body has an open energy system that is in instant exchange on the subtle energy level just as it is in other levels. The first boundary between the body's energy system and environment is on the level of what we aware, as a bounday our clothes affect the energy exchange in both directions. The object of this research is to study how this boundary can affect the quality of energy exchange in order to bring harmony within the human subtle energy system and have positive effect on the vitality, emotional and mental levels. In this research fashion design sketches were drawn. Their energy determined qualitatively, one sketch selected and modified by BioGeometry design principles and then , ten creative fashion designs applied which principles and elements of both BioGeometry and fashion design are analyized. Further studies needed to complete full observation.

Electroplating sludge contains huge of Ni. Bioleaching is found to be the best method to remove heavy metals. But, the temperature play vital role. In the present study, the influence of temperatures on the removal of Ni from electroplating sludge was investigated using bacteria, Acidithiobacillus ferrooxidans. Results showed that the maximum of 90.5% Ni was removed from the sludge under the temperature maintained at 37 °C. It was found that the rate constants obtained for Ni bioleaching at 37 °C was high.

Intramedullary metastasis is extremely rare, this report describes a case of a women aged 52, with a metastatic breast cancer spreads to brain, spine (vertebrea) and bones under chemotherapy. The patient consults for weakness and troubles walking. MRI has shown intra medullary metastasis. Our goal through this report is to describe a new case of a breast cancer intra medullary metastasis knowing that the most common primitive tumor was related to lung cancer.

The main contributions of the present work include the design of a computer-aided detection (CAD) system for the segmentation and classification of breast cancer. A comparison of segmentation and classification methods of both masses and micro-calcifications, tapping of a new entropy function called Hanmandlu and Anirban entropy function. The new entropy function outperforms over the Shannon’s entropy and drastically improved the classification accuracy by 5%. Next is development of a modified rough set quick reduct algorithm for the reduction of dimensionality in the feature selection prior to the classification. On the average the reader’s sensitivity can be increased by 10% with the assistance of our CAD system. Our finding indicated the potential of CAD to reduce the false negative rates by 50-75%. The average execution time is 5 seconds per image.

Peripartum cardiomyopathy is a rare disease accountable for giving a heart failure, which affects women in the last month of pregnancy or within the first 5 postpartum months. Early signs and symptoms of heart failure may not be seen, they are often considered as a normal part of pregnancy. When such symptoms and signs are not diagnosed or managed accurately, the consequences can be deleterious for the patient. We are going to briefly report a case of a 28-years-old woman, without any preexisting structural heart disease. The woman, after 3 months of vaginal delivery following normal pregnancy, was admitted for cardiogenic shock and distal lower Limb Necrosis secondary to peripartum cardiomyopathy. Such complications are uncommon, and the management was not easily accepted by the patient.

The chemical composition of the essential oils from the leaves of Acalypha hispida and Acalypha wilkesiana obtained by hydro distillation, were analyzed by Gas chromatography linked with Mass spectrometry. The main constituents of the essential oil from A. hispida were neral (11.04%), citral (12.87%), 6,10,14, trimethyl-2-pentadecanone (13.43%) and n-hexadecanoic acid (14.69%) while neral (30.66%) and citral (36.10%) which are monoterpenes were the major compounds in the oil of A. wilkesiana. The essential oils were tested for toxicity against brine shrimps larvae (Artemia salina) and showed LC50 values of 122.28µg/mL and 212µg/mL respectively while their activity against Anophelis gambiae reveal LC50 values of 125µg/mL and 83.33µg/mL respectively.

Security threats for the network services have been constantly increasing day by day. Distributed denial of service (DDoS) attack is one such kind of security threat which involves multiple systems generating a large amount of traffic towards a target machine and thereby making any service from that target machine or server unavailable to its clients. This threat by nature needs no control over the target system. Traditional methods of detecting DDoS attacks are mostly centralized in nature and highly disadvantageous. To overcome the disadvantages of those schemes, we propose a distributed methodology which involves installing the attack detectors at various parts of the network. Each router in the network will monitor the traffic flowing through it and if any anomaly in the traffic pattern is detected, it will raise an alarm to the nearby routers. The alarm propagates to all the routers through which the attack flows. By this way a tree like construct is made, which will have information about number of alarms raised and the path of the attack flow. If the construct shows any converging pattern then it is declared as DDoS attack.

 Colonialism has been conceived as a policy and practice of a strong power extending its control territorially over a weaker nation or people. So, a colonial territory is that political entity over which a stronger power exercises political control. From around the mid 19th to about the mid 20th century, what we know today as the Nigerian nation-state was a classical colonial territory. Without bothering to obtain their consent or allow indigenous centripetal leaders emerge, a stronger British power proceeded not only to extend its control over the territorial space, but railroad its diverse peoples and cultures into a commonwealth they neither understood nor bargained for. What followed was a struggle of one group against the other, or others, either to ingratiate itself with the colonizing power, or assert itself against its pretensions. When the later disposition failed or became forlorn, all groups settled more or less for the former. In the midst of this novel social setting, the various cultural norms of transparency and sublime modesty in public affairs began to give way for new social ethos of competition and graft. The emerging urban areas provided a perfect arena not only for the social contact of the various culture groups, but one that saw to the flowering of seeds of dichotomy and discrimination amongst the people. This paper seeks to situate the so-called “culture of corruption” in Nigeria within the colonial environment, and posits that the aphorism, ‘culture of corruption’ is actually alien to indigenous Nigerian peoples. It contends that if the current so-called ‘War against Corruption’ must be successfully pursued, then the sublime virtues of indigenous cultures need to be propagated and adopted as national ethos. Key words: Colonialism, Corruption, Nigeria, Indigenous Culture, National Ethos.

In this paper, we have studied the photoluminescence spectroscopy of several HEMTs AlGaN/GaN high electron mobility transistors produced by molecular beam epitaxy growth. The heteroepitaxy of the nitrides of elements III is made on substrates of different nature: Silicon, Si [111]), Sapphire Al2O3 and Free-standing GaN. We thus observed constraints during growth, related to the disagreements of the mesh parameters. The EA activation energy of the free exciton A, measured by photoluminescence, varies linearly with the biaxial strain ?xx, obtained by X-ray diffraction. In addition we noticed that an evolution of the aluminum assay of 0.5% from one sample to another 5% reveals a shoulder that evolves respectively to a plateau, reproducible at different levels of excitation. This is how we interpret this phenomenon as a manifestation of 2D gas on the photoluminescence spectrum

Teachers are the back bone of society. Public and private schools are directly related with student achievements. A good school uses different strategies for student achievement. If the teachers are competent and teach students in better way, then they can achieve their goals in every field of life. This paper attempts to study the comparison of students’ achievement between public and private schools. This study shows that students’ achievement is based on quality education. Some factors affect the students achievement such as parent background, involvement of parents, low income, environment of a school and physical facilities.In this way this study shows that what influence the academic difference of public and private schools on students achievement. This study will be descriptive in nature therefore descriptive survey method of research will be used. The population of this study will comprise of all the secondary school students of distric Vehari. The sample of twenty secondary (private & public) schools will be selected from tehsil Vehari. Out of 1000 students 280 will be selected by using simple random technique. Questionnaire will be used to collect data from respondents. The collected data will be analyzed statistically by using (SPSS) software.
