 Abstract

In order to verify risk factors, clinical, bacteriological and therapeutic characteristics of ecthyma gangrenosum in the pediatric population. We retrospectively reviewed all cases diagnosed with ecthyma gangrenosum from January 2013 to September 2019 at Mohammed VI University Hospital in Marrakech. We report eleven cases (six girls and five boys, aged between 5 days and 15 years). Medical history showed two cases of primary immunodeficiency, a case of acquired immunodeficiency, two cases of malignant hemopathy, a premature newborn, a case with reccurent infections. All patients presented at the emergency department for skin lesions associated with fever. Bacteriology of skin sample isolated Pseudomonas aeroginosa in all cases. All patients received combined antibiotic therapy. Nine patients evolved favorably and two patients died from septic shock. Ecthyma gangrenosum was the presenting manifestation of chronic granulomatous disease in one case. Ecthyma gangrenous is a serious infection, early and appropriate antibioc therapy is primordial to improve the prognosis. Immunological evaluation is recommanded to rule out unkowen immune deficiency.

Abstract:: The maximum amount of sensor energy is consumed during communication. To prolong the Network Lifetime of a Wireless Sensor Network (WSN), there is a need of optimum utilization of sensor energy. Scheduling in MAC layer plays an important role in the design of WSN to avoid collision and conserve more energy. Distributed energy aware MAC protocol (DE-MAC) is one such efficient MAC Protocol that addresses the energy management problems in WSN. This paper proposes an extension of DE-MAC technique by allocating varying time slots to the nodes based on their residual Energy level. Energy of all the nodes is exchanged at regular intervals and accordingly the nodes with lesser energy are allocated lesser time-slots for transmission and are made to sleep more. Simulation results for Average residual energy, Throughput and Packet delivery ratio are compared with DE-MAC for performance analysis.

 Abstract

Language teaching in elementary schools throughout Indonesia has become a matter of obligation. The Covid-19 pandemics has been transforming characteristics in language learning, since it needs online learning to prevent Covid-19 clusters. The purposes of this study are mapping (1) digital native characteristics in indonesian elementary schools during covid-19 pandemics, and (2) second language teaching for young learners in indonesian elementary schools during covid-19 pandemics. Method that uses in this study is educational ethnographic research. The results show that (1) there is a socio-cultural gap in language teaching during Covid-19 pandemics, and (2) language teaching is should be based on learning community. In conclusion, the learning community have to be developed based on online activities in virtual classroom on language teaching.

 Abstract

Electronic Navigational Charts (ENC) is the human modern science navigation equipment technology that converts nature geographical physical information features to electronic date sets information features is the display picture system that supports all marine navigation. In addition, enabling the mariner to operate and execute all navigation planning, control and monitoring for safety navigation from one place to another. ECDIS equipment complying with SOLAS requirements can use as an alternative to paper charts. The key point is to reduce the navigational workload compared to using the paper chart. The paper assessed the safety setting such as safety contour Setting, Shallow contour settings, deep contour setting and analyses The main common navigation equipment failures such as ECDIS which tend to loose position (position of cursor) because of power interruption and an untimely chart update also cause the vessel to deviate from control vessel sailing along desired track. In addition, paper recommended the navigator should transfer navigation to the back-up system. The actions to taken in the case of an ECDIS Failure and solutions in order to keep the system running. The future ECDIS functions should be providing information support for the full realization of navigation automation.

 Abstract

The last few years have seen increasing usage of cold formed steel sections as load bearing members as opposed to secondary systems. In this context a study is being made to analyse Coupled Channel sections to arrive at design strength criterion in compression. The direct strength method of design for cold formed steel sections has been validated over the years through research and the same has been incorporated in the standard codes of practice in the countries like USA and Australia. ABAQUS and CUFSM has been extensively used to perform Finite Element analysis and Finite Strip method of thin walled cold formed steel sections and the results are compared to each other. Hence the analysis is being done on CUFSM and ABAQUS. The design strength curves will be arrived at using direct strength method. In this study, the behavior of Coupled Channel sections under the action of axial loads has been carried out. In ABAQUS, the loads are applied on both ends. The simply supported and clamped end conditions are considered.

 Abstract

Women education can create a peaceful society, where every individuals (men and women) would be loved and peacefully co-operate with each-other in the world. In a small word we say that to we educate a girl child means to educate a family. In general concept every person believes that educated women are able to play a vital role in developing India. The research used document analysis method for data collection, and show that how women education can set up a non-violence, truthful sustainable, women empower and valuable in society. Unfortunately we find different barriers of women education in India educational area.

 Abstract

In the present study fractals are grown using the bacteria colony. For this purpose cell is designed and the growth processes are studied using this cell. Different colonies are studied at different temperatures. There are large number of parameters which control the growth process. In the on going process images are photographed with the help of video camera. Fractal dimensions of these shapes are calculated using computerized box counting method. The results obtained are compared and discussed. It was seen that the growth satisfy the Laplace equation.

 Abstract

The formation of clusters and cluster heads in wireless sensor network(WSN) leads to overhead. Such overhead is reduced by using proper medium access control design . Reliability and sleep scheduling of nodes is achieved by such protocols. There are two types of Medium Access control protocol, they are contention and contention free based protocol. The contention based protocols are CSMA/ CA. There is heavy contention of nodes for channel access [1]. When node density and network traffic are moderate or high, they suffer high collision rates because of concurrent channel access, which in turn increases the packet drop rate. As a result, for large networks contention based protocols are not suitable. This drawback is overcome by using contention free protocol such as TDMA [2] [3]. In such schemes, a specific time slot to is assigned by the cluster head to each node in the cluster, and the node uses that time slot to transmit. The sleep time of nodes increases by using TDMA. The reliability and the energy efficiency of the network are also improved. In many of the clustering techniques that utilized TDMA hop selection and probability of packet failure was not considered. Packet loss introduces an overhead for both intra and inter cluster communication. This makes network unreliable as energy consumption increases. This aspect is studied by determining packet failure probability. Here an energy optimization technique and a packet failure likelihood estimation technique are presented. The proposed energy efficient model performs better than the existing LEACH in term of lifetime of network. When the number of nodes are increased, results show that proposed model performs better than LEACH(Low Energy Adaptive Clustering Hierarchy)
