Companies need project portfolio management (PPM) to deal with the increasing number of projects and used it to ensure strategic arrangement and adequate use of available resources. Moreover, customers were demand more attention from their suppliers. The management of a project portfolio and the corresponding customers, supplier’s engagement signified a link between PPM and external stakeholder’s engagement. Supplier engagement in project portfolio management success had become an increasingly popular technique for improving project capability and project performance in PPM. By defining the range of PPM, this study hypothesized a connection between external stakeholders like customers and supplier’s engagement and project portfolio management success. The results were based on a cross-sectional sample of 100 well known Software Houses in Lahore, Pakistan. Study employed Pearson’s correlation and step wise hierarichal regression to find the results. Study found a significant relationship between customers and supplier’s engagement and PPM success. While moderating effect of role clarity showed partial moderation.

The study was under taken to find out the effect of different organic manure on the yield and carbon sequestration potential of fodder cowpea. Result revealed that green fodder yield were significantly (P<0.01) higher in improved farmyard manure, vermicompost and enriched farmyard manure application. Similarly carbon sequestration potential was significantly higher in improved followed by vermicompost and enriched methods. It was concluded that the application of vermicompost, improved and enriched manure increased fodder yield and sequestered higher carbon from the atmosphere than other treatments.

In today`s global scenario the demand of Wireless communication service is growing rapidly. In order to serve a high user population in a limited spectrum, using dense grids of microcells and picocells is one of possible schemes. While small cells relieve the capacity problem, frequent movements of mobile users across cell boundaries pose a big network control challenge: handover In personal communication networks (PCN) supporting network-wide handovers, new and handoff requests compete for connection resources in both mobile and backbone networks. Due to limited range of transceivers, mobile users can communicate only with base station that reside within the same microcell at any instant of time. The number of handovers during a call will increase, as the cell radii decreases, thus affecting Quality of Service (QoS). As the handoff rate increases, bandwidth management and traffic control strategy (call admission control, handover procedures etc) become more challenging problems in wireless ATM networks. Thus in a wireless environment, we need to consider two additional QoS parameters; dropping probability of handoff calls and blocking probability of new calls. Handoff calls require a higher congestion related performance i.e., blocking probability relative to new calls because forced call terminations due to handoff call blocking are generally more objectionable than new call blocking. In general, most of the previously proposed schemes for radio channel allocation in cellular networks reduce handoff call blocking probability substantially at the expense of increasing the new call blocking probability by giving higher priority to handoff calls over new calls in admission control. This reduces the total admitted traffic and results in inefficient utilization of wireless channels. The tradeoff between the new and handoff calls blocking probabilities should be defined. In this paper, a modified Hybrid scheme has been proposed for handover in ATM-based PCN, which combines reservation and queuing schemes for handoff calls. Also , the scheme assigns the handoff reserved channels to new calls depending on the locality principle in which the base station with the help of location estimation algorithm in the mobile location centre predicts the position of the mobile terminal. Here the FIFO and Measurement Based Priority Scheme (MBPS)queuing scheme are used. Thus the modified Hybrid Scheme is designed to have a remarkable reduction in forced termination Probability (FTP) along with to improve channel utilization while satisfying the QoS of the calls.

Intra-orbital foreign corps is relatively rare cause of consultation in neurosurgical and ophthalmologic emergencies. Anatomical contiguity between the orbit and the middle cranial fossa is the reason why a neurosurgical approach could be necessary, for the extraction of a foreign body. This case report is about a06 years old girl, admitted to ophthalmologic emergencies, for intra-orbital foreign body, through a wound located at the inner corner of the left eye. The extraction, of a pencil of 06 cm, has been carried out jointly by neurosurgeons and ophthalmologists by a sub-conjonctival approach. The medium-term follow up is 12 months, a surgical wound healed, but no functional recovery of vision or eye movement. Foreign intra-orbital corps are rare in neuro-ophtalmological emergencies, require vigilance in clinical diagnosis as they may go unnoticed. Adequate imaging, and relevant therapeutic approach aimed at “surgical” extraction, are necessary, because, foreign corps are exposed to the infection, panophtalmitis, brain abscess, or even very serious complications).

Synovialosarcoma is one of the most common soft tissue sarcomas. Despite its name, the synoviolosarcome does not seem to be of synovial origin, but is rather derived multipotent cells. Paradoxically, the more often it is tumors that are within distance joints. Synovialosarcoma is in order of frequency the third histological type among soft tissue sarcomas. Complete surgical removal of the tumor is the basis of traitement.la adjuvant radiotherapy for appears beneficial residual tumor. As for chemotherapy, it remains to be explored its role.

Galeazzi fracture involves a fracture of the radial shaft and a distal radioulnar dislocation (RCD). RCD lesions are almost always associated with isolated fractures of the radius. They often go unnoticed and their ignorance strike prognosis, because disorders pronosupination and the potential impact on the entire wrist. It was described by Sir Astley Cooper in 1866 for the first time. Judet in 1913 and in 1929 Schneck also described this injury but it is only since 1934 following the publication of 18 cases by Ricardo Galeazzi lesion that bears his name. This fracture is rare and only occurs in 6.8% of fractures of the forearm according to the review of 1934 fractures Moore.

Good governance and human rights are mutually reinforcing. Human rights principles provide a set of values to guide the work of Governments and other political and social actors. They also provide a set of performance standards against which these actors can be held accountable. Moreover, human rights principles inform the content of good governance efforts: they may inform the development of legislative frameworks, policies, programmes, budgetary allocations and other measures. However, without good governance, human rights cannot be respected and protected in a sustainable manner. The implementation of human rights relies on a conducive and enabling environment. This includes appropriate legal frameworks and institutions as well as political, managerial and administrative processes responsible for responding to the rights and needs of the population. Good governance is the exercise of authority through political and institutional processes that are transparent and accountable, and encourage public participation. Whereas human right refers to the standards set out in the Universal Declaration of Human Rights. Good governance led by human rights values create avenues for the public to participate in policymaking either through formal institutions or informal consultations. They also establish mechanisms for the inclusion of multiple social groups in decision-making processes. They may encourage civil society and local communities to formulate and express their positions on issues of importance to them. In the realm of delivering State services to the public, good governance reforms further human rights when they improve the State’s capacity to fulfil its responsibility to provide public goods which are essential for the protection of a number of human rights, such as the right to education, health and food. Reform initiatives may include mechanisms of accountability and transparency, culturally sensitive policy tools to ensure that services are accessible and acceptable to all. In context of rule of law, human rights-sensitive good governance initiatives reform legislation and assist institutions ranging from penal systems to courts and parliaments to better implement that legislation. Good governance initiatives may include advocacy for legal reform, public awareness-raising on the national and international legal framework, and capacity-building or reform of institutions. Anti-corruption measures are also part of the good governance framework.

Public concern for ecological issues has shown an increase over the past three decades. In this modern era of social marketing, ethics in business have become strategic decisions in marketing. Marketers have started responding to consumers’ growing ecological consciousness by developing environment friendly products. Consumers have positive attitudes towards green buzz but this positive attitude in environment issues is not translated fully into the interest consumer show in their scrutiny behaviours. This study determines to find the impact of demographic factors upon green perception. A survey was conducted to gather responses from respondents of Amritsar and Jalandhar region (Indian cities). A total of 119 respondents, responded to a 10 questions questionnaire. The result indicated that Gender plays a significant role in formation of green perception.

Several compression for 3-D medical images have been proposed in the past year, some of which proved resolution and quality scalability up to lossless reconstruction. A novel 3-D scalable compression method for medical images with optimized volume of interest (VOI) coding were presented in this paper. The method is presented within the framework of interactive telemedicine applications, where different remote clients may access the compressed 3-D medical imaging data stored on a central server and request the transmission of different VOIs from an initial lossy to a final lossless representation. The VOI are decoded at the highest quality possible at any bit-rate, while allowing for the decoding of background information. The objective and subjective quality evaluation on various medical volumetric datasets shows that the proposed algorithms provide competitive lossy to lossless compression. The modified version of the embedded block coder with optimized truncation (modified EBCOT), tailored according to the characteristics of the data, encodes the residual data generated after prediction to provide resolution and quality scalability. The Digital watermarking is the process of embedding information into a digital signal which may be used to verify its authenticity or the identity of its owners, in the same manner as paper bearing a watermark for visible identification. Performance evaluations based on real 3-D medical imaging data showed that the proposed method achieves a higher reconstruction quality, in terms of the peak signal-to-noise ratio, than that achieved by 3D-JPEG2000 with VOI coding, when using the MAXSHIFT and general scaling-based methods.

The present study aimed to map irrigable lands in Bugesera Agro Ecological Zone (AEZ) in the Eastern Province of Rwanda, using spatial information’s. The related Concerns were to determine the suitable area for irrigation that can include all different parameters which influence irrigation. The methodological approach consisted of processing Aster Landsat and DEM; gathered by Radar Satellite acquired at CGIS/NUR, using appropriate packages-software ILWIS 3.3, Erdas8.7 and ArcGIS 9.2. Satellite image was used to determine land use and land cover classification of the study area and the DEM to determine slope classification. The results showed maps that are describing different type of layers classified according to purpose of irrigation, slope, water proximity, percentage of clay and sand and type of land use. Those maps helped to produce a model design that conducts us to determine the most suitable area for irrigation. The model designed would be used as a planning tool to optimize agriculture in the Eastern Region of Rwanda.
