Abstract: This study illustrates the classification of the rock mass and evaluation of rock squeezing, rock burst potential, deformation modulus along the proposed tunnel alignment of small hydropower in Swat Valley, Khyber Pakhtunkhwa (KP), Pakistan. The field and laboratory studies were conducted to classify the rock mass by using geomechanical classification systems i.e. Rock Mass Rating (RMR), tunneling quality index (Q), Rock Mass Index (RMi). The empirical relations classified the ground as non-squeezing and minor to non-squeezing conditions, respectively. Whereas, other methods depict minor to medium bursting potential along chainage 1+000 to 4+000 m, while results along chainage 2+400 - 2+800 m present medium to high bursting potential. Furthermore, numerical analyses were carried out by RS3 for elastic and plastic conditions in order to assess the total displacement of each section in unsupported and supported conditions. The results gave maximum displacement along chainage 2+400 - 2+800 m (19.2 mm in unsupported and 16mm in supported condition) and minimum displacement along chainage 0+876 - 1+000 m (1.4 mm in unsupported and 1.3 mm in supported condition). Hence, the estimated support by empirical methods has been optimized by using numerical analyses for the stability of rock mass along the tunnel.

Abstract: The Northern segment of Pakistan, especially Balakot city is affected up to large extent by the landslides. Tectonically, it lies in the proximity of Hazara Kashmir Syntaxis and other two active regional faults: Main Boundary and Hazara Frontal Thrusts that traversing right through the Balakot town. This study focuses on the evaluation of slopes near Balakot town in static and pseudo-static condition. A geological map is produced at 1:24,000 scale to separate various rock and soil units. During reconnaissance study, two slopes were selected which seem prone to sliding. The procured data on condition of natural slope, properties of material entailed, structural setting, and vegetation cover distribution was gathered. Discontinuity Surveys of slopes were carried out to collect discontinuity parameters. Kinematic analyses were performed on DIPS v. 7.0 to assess mode of failures based on joints data. Limit equilibrium analyses were carried out at Slide v. 7.0 to check factor of safety at different conditions. The study concluded that the slopes were affected by the plane, wedge and toppling failures, while although in seismically active zone, circular failure is not likely.

International Journal of Science and Engineering , 2010, DOI: 10.12777/ijse.v1i2.1231
Abstract: Membranes are being increasingly used as a valuable separation tool in laboratory as well as in industrial processes. Continual development of new membrane materials is crucial to sustain and expand the growing interest in this technology and modern polymer chemistry is highly proficient in tailoring polymers with desired properties such as increased mechanical, thermal and chemical stability. Cellulose acetate (CA) is one of the membrane polymers that has been used for aqueous based separation and used as both reverses osmosis (RO) and ultrafiltration (UF) membranes. This paper presents investigation of influence of casting machine speed in membrane preparation. CA is used in this study. That was CA-398-30 with average acetyl content 39.8 wt %. Non solvent used is water and the solvent is 99.7 % organic Dimethyl Sulfoxide (DMSO). The homogenous CA/DMSO solutions were prepared by dissolving CA in DMSO solvent. The CA concentration were varied 13 and 16 % while casting solution speed were varied from 20 to 80 mm/sec with distance cutting machine were fixed at 14 cm. In addition, non solvent in coagulation bath also were varied by 100 % water and 10 % DMSO in water. The results of this experiment describe effect of casting machine speed to water permeability. The effect of CA concentration to water permeability shows the adversative result between 13 and 16 % CA in 100 non solvent water. The similar result also observed in 10 % DMSO in water.

Abstract: The sexual Fus3 MAP kinase module of yeast is highly conserved in eukaryotes and transmits external signals from the plasma membrane to the nucleus. We show here that the module of the filamentous fungus Aspergillus nidulans (An) consists of the AnFus3 MAP kinase, the upstream kinases AnSte7 and AnSte11, and the AnSte50 adaptor. The fungal MAPK module controls the coordination of fungal development and secondary metabolite production. It lacks the membrane docking yeast Ste5 scaffold homolog; but, similar to yeast, the entire MAPK module's proteins interact with each other at the plasma membrane. AnFus3 is the only subunit with the potential to enter the nucleus from the nuclear envelope. AnFus3 interacts with the conserved nuclear transcription factor AnSte12 to initiate sexual development and phosphorylates VeA, which is a major regulatory protein required for sexual development and coordinated secondary metabolite production. Our data suggest that not only Fus3, but even the entire MAPK module complex of four physically interacting proteins, can migrate from plasma membrane to nuclear envelope.

Abstract: Reincarnation is one phenomenon that has always generated great controversies. While some people, based on personal experiences, are convinced of its possibility, some others outrightly denounce it. The Yoruba Muslims with regards to belief in reincarnation are divided into two; a section among them believes in the phenomenon, another section, however, opposes it and denies its occurrence. This study, contextualising the phenomenon within the framework of Islamic orthodoxy, attempts reconciliation between the two opposing views of Yoruba Muslims on reincarnation.

Abstract: The efficient use of energy is of prime importance in all sector of the economy. Energy cost is a significant factor in economic activity on par with factors of production like capital, land and labor [1]. The imperative of an energy shortage situation calls for energy conservation measure, which essentially means using less energy for the same level of activity. A comprehensive energy audit of Vitamalt Nigeria Plc, Agbara was carried out using portable thermal and electrical instruments with the objective of studying the present pattern of energy consumption and identifying the possibilities of saving energy in the plant. Collected, was a five year (2000-2004) data on energy consumption of Vitamalt Nig. Plc. The data were evaluated and analyzed to determine the present energy performance level of the firm. A complete energy balance of the factory was carried out to relate energy input, conversion efficiency with production output in order to identify areas of energy wastages/losses and savings that can be achieved. Energy performance parameters such as Energy intensity, Energy productivity and Normalized performance indicator (NPI) were used as a measure of assessing the energy performance of the plant. The NPI calculated over the span of five years gave an average of 1.2 GJ/m2 indicating a FAIR range in energy performance level classification (1.0 - 1.2) while significant savings and improvement in energy usage is achievable. Maximizing efficiency of existing system, optimizing energy input requirement and significant capital investment in procuring new energy conserving equipment must be made for the energy performance level to fall into a good range classification (less than 0.8).

Abstract: Rural poverty is a major socio-economic issue of many of the developing countries including Pakistan. Different strategies are being used to combat with rural poverty including disbursement of micro-credit by different state or non-state institutions in the country. In order to find out the impact of micro-credit on livelihoods of rural poor in the Punjab province of Pakistan, the present study was designed. Survey research design using mix method approach to data collection was used. Both probability (simple random) and non-probability sampling procedure was adopted for the selection of study objects. The total sample size of study was 150 (both male and female recipients of micro-credit). Descriptive (Frequency, %, mean, SD) and inferential statistics (multiple regression) was used for the interpretation of data through SPSS. It was concluded from the results that majority of the recipients of micro-credit was belong to young age category (mean age 36 Years) with low educational status. The educational level of rural women is very low compared to men. A large majority (78.0%) of the micro-credit recipients were female having low monthly income (119USD). Disbursement of micro-credit was one of the major strategies to cope with the issues of rural poverty. The average loan size as received by respondents was continuously increasing every year. In the research area illiteracy was on the top among other reasons of poverty with highest mean value (4.49/5.00). Majority of the respondents reported that micro-credit had significant impact in uplifting their livelihoods. It was suggested that micro-credit disbursement to the poor is not a sustainable solution to reduce poverty. The state should start other income generation activities in rural areas.

Journal of Software Engineering and Applications (JSEA) , 2017, DOI: 10.4236/jsea.2017.1012049
Abstract: With continuous evolution in software industry, security is becoming very important in software projects. However, in many development methodologies, security is thought to be added in the project at later stages of the development lifecycle. There are also many proposed methodologies where the security measures are considered at requirement engineering stage of the development lifecycle, but many of them still do not seem adequate for applicability due to the reason that these approaches do not provide sufficient support for mapping the security requirements to the later stages of development. So, we are in need of a software requirement engineering approach, which is not only helpful in security requirement specification at requirement engineering stage but also provides support for using the specified security requirements at later stages of development. To meet this requirement, we introduce a new method Secure and Traceable Requirement Engineering Process (STREP). This method also helps the non-security-expert requirement engineers to specify requirements in such a way that the specified requirements can be used to derive security related test cases. STREP method not only deals with security issues of the system at requirement engineering stage, but also makes the security requirements more traceable to be used at later stages of development lifecycle, and as a result, secure systems are produced that are also usable as the customer wishes.

Abstract: Since, 2003 when hostilities broke out in Darfur region of Western Sudan, the African Union has been leading international community efforts at restoring peace to this trouble region. The organization deployed ceasefire monitoring commission, peacekeeping force and under Nigeria leadership broker peace agreement between the warring parties. From all indications the Darfur Peace Accord [DPA], brokered in Abuja, Nigeria has not resulted into the normalization of the security and political situation in Darfur as was envisaged. The apparent lack of robust capacity by the African Union Mission, AMIS to stabilize the security situation in Darfur reinforces the call for the United Nations to intervention. With a robust mandate, secure resource base and better logistic capabilities, the African Union-United Nations Hybrid Mission in Darfur, UNAMID has been proactive in enhancing the protection of its personnel, bases and equipments and greater capacity in the provision of security for safe delivery of humanitarian assistance and protection of civilians. Much as the deployment of UNAMID mission has brought semblance of security, there continue to exist challenges that are undermining security and militating against the achievement of durable peace in Darfur this paper argued. Key words: African Union; Conflict; Darfur; Peacekeeping; Security Résumé Depuis 2003, lorsque les hostilités ont éclaté dans la région du Darfour au Soudan occidental, l’Union africaine a dirigé les efforts de la communauté internationale à rétablir la paix dans cette région trouble. L’organisation a déployé commission de suivi cessez-le-maintien de la paix la force et sous la direction du Nigeria courtier accord de paix entre la guerre parties. de toutes les indications de l’Accord de paix sur le Darfour [DPA], négocié à Abuja, au Nigeria ne s’est pas traduite dans la normalisation de la situation sécuritaire et politique au Darfour comme cela a été envisagé. le manque apparent de forte capacité par la Mission de l’Union africaine, la MUAS à stabiliser la situation sécuritaire au Darfour renforce l’appel à l’Organisation des Nations Unies à l’intervention. Avec un mandat robuste, base de ressources en sécurité et de meilleures capacités logistiques, l’Union africaine- Nations Unies au Darfour, la MINUAD a été proactif dans le renforcement de la protection de son personnel, des bases et des équipements et une plus grande capacité dans la fourniture de sécurité pour une livraison s re de l’aide humanitaire et la protection des civils.
