This paper investigates academic supervision that is pivotal for the development of academic research and the evolution of higher studies. One of the main difficult challenges that teachers encounter is supervising their candidates. This process requires a lot of patience, hard work and perseverance. Similarly, the fact of being supervised students creates a lot of pressure on the part of the supervisees in which they should prove themselves as researchers who deserve a particular academic qualification. Although the academic virtues of supervision imply guiding the supervisees, helping them to locate data that is relevant to their topic and improving the quality of their work, there may exist several problems and sensitivities between the supervisor and supervisee. This study aims at identifying the factors, which contribute to the low-quality of the academic works, such as dissertations and theses. In order to investigate the issue, questionnaires were administered to 83 participants, namely 30 teachers (supervisors), 3 Doctorate candidates and 50 Master 2 students involved in different specialties at Mohamed Kheider University of Biskra in Algeria. Through these questionnaires, it was attempted to diagnose some of the factors behind the difficulties encountered in the supervision process and the reasons that lead to problems in the supervisory relationship. The latter revealed that the superviseesí deficiency and supervisorsí inefficient supervisory skills are the main inducements for the failure of the supervisory process, which may influence in many cases the quality of the studentís graduation work.

The study was planned to carry out the molecular epidemiology of PPR. The data (n=143) were collected from two village goat and a market of Shibgonj, Bogra, Bangladesh and nasal swabs (n=72) were collected from clinically suspected goats from twelve Veterinary Hospitals of seven districts during July-October 2012. The virus was detected by RT-PCR technique in which PPRV: F1b & F2d; NP3 & NP4 primers were used to detect and F gene of three isolates (Named PPRV/BD/Rajshahi-1/2012, PPRV/BD/Rajshahi-2/2012 and PPRV/BD/Bogra/2012) were sequenced and phylogenetic analyses were performed. The survey resulted that the overall morbidity and mortality were 19.79 and 11.51 % respectively in the post outbreak period as well as the molecular study confirmed that 33.33 % samples were diagnosed as positive and this can be interpreted as, the goat were suffering from high fever with or without diarrhea still incubating the disease, the highest morbidity and mortality were found in male goats and in goats of age between 4-12 months. The N gene was revealed 100% confirmatory diagnosis in comparison with F. The findings of the nucleotide sequences of F gene fragments revealed that each of the isolates belonged to Lineage IV and most closely related to the others obtained from Gene Bank. PPRV/BD/Bogra/2012 has 100% homology in terms of partial sequence, 289bp of F gene with the viruses- Narayangonj/2009(Ac.No.JX094440), Dhaka/2009(Ac.No.JX094438) and BAU/Mymensingh/2010 (Ac.No.JX094436).

An integrated approach which involve interpretation of Landsat ETM+, aero-magnetic and aero-radiometric data was undertaken over the eastern flank of Ilesa-Ijesha schist-belt, Nigeria, with an objective of delineating structural and lithological features that favour mineral deposition within the study area. The analysis of Landsat ETM+ data revealed four distinct lineament trending NNE Ė SSW, NNW Ė SSE, NWW Ė SEE and NE Ė SW. The lineaments density ranges between 0 and 2.67 m-2; higher over and around lithological contacts and areas underlain by felsic rocks. The application of analytic signal, tilt derivative and 3D-euler filters on aeromagnetic data allow identification of series of anomalies suspected to be lithological contacts, alteration zones, magnetic source anomalies and overall basement characteristics. The primary trend of structural features producing magnetic anomalies is generally NE Ė SW, which corroborate the Landsat ETM+ result. The analysis of radiometric datasets revealed geochemical information on potassium (K), thorium (Th) and uranium (U) concentrations, and results obtained was used to identify impacts from alteration and rock contacts and define bedrock lithology within the study area. The ternary-image generated form radiometric data interpretation show distribution of the radiometric intensity which correlated well with geological structures and lithology in the area.

A weed survey was carried out in seven hamlets in Dongola area namely:, Eldoum Elawazma, El Selaim basin, Elatroona, Irtidi, Elmasakeen, Kawa and Agja during the winter season of 2015/2016 to determine the most common and prevalent weed species associated with garlic (Allium sativum L.) and onion (Allium cepa L.). For each crop, a stratified random sampling procedure was adopted, whereby, each hamlet was divided into fields of which 10 were randomly selected. Number of individual weed species was determined in 10 quadrates each 1 m2. The field density, field frequency, field uniformity, relative field density, relative field frequency, relative field uniformity and relative abundance of the species were determined. Data revealed the presence of 26 species of annual and perennial weeds belonging to 15 families in garlic and 28 species belonging to 15 families in onion. The highest number of species occurred in Elmasakeen and Irtidi hamlets whilst the lowest was recorded in Kawa hamlet in both crops. In all parameters measured, the dominant weed species prevailed at higher values in garlic than in onion. Sinapis arvensis, Cynodon dactylon, Malva palviflora, Convolvulus arvensis, Chenopodium album and Sorghum arundinaceum displayed the highest relative abundance in both crops. Trigonella hamosa also occurred at high relative abundance in onion. Species with moderate relative abundance in garlic included Cyperus rotundus, T. hamosa, Eruca sativa, Chenopodium murale and Sinapis alba. Whilst C. murale, Datura stramonium, Gynandropsis gynandra, E. sativa, Sonchus oleraceus and Amaranthus graecizans were moderately abundant in onion.

Bioavtur plays an important role in the development of world energy security because most of the aviation demand has not been fully met from fossil energy production. The development of Bioavtur itself is still hampered by the fulfillment of the aircraft's very strict fuel technical qualifications. The use of Bioavtur in the CO2 gas recycling cycle, the reduction of exhaust emissions can be generated not only from physical properties and production processes alone using the process of HEFA, ATJ and FT, where Bioavtur does not contain sulfur but CO2 generated from combustion can also be absorbed by Plants that produce raw materials for Bioavtur. Methodology used secondary and primary data collection to obtain economic simulation. To generate and achieve goals in this activity, of course require data. The types of data used in this study are primary and secondary data. Stages of data collection / survey in this study include data collection both qualitative and quantitative to aspects related to economic simulation by calculating NPV, IRR, ROI, B / C ratio and PBP. Calculation of economic simulation with first scenario with BAU scenario (Business as Usual), this scenario contains the calculation condition for raw material price and product selling value adjusted to current market price condition. The second scenario is made so that this study can produce the economic quantity that feasibility. Especially for this second scenario will be adjusted to the price of raw materials in order to provide a decent economic value. The result of analysis with BAU scenario with raw material price of CPO $ 688.5 / Ton and product selling price as shown in table 2. Generating an unfeasible economic quantity, this is indicated by the value of NPV $. -245.108.330, the value of the ratio B / C -13.55, this is because the value of production costs is higher than the value of sales of its products. The value of production costs because the price of CPO is higher than the selling value of products, especially bioavtur as the main product. After analyzing the sensitivity on CPO price of $ 531.29 / Ton with 3% price increase, the price of CPO becomes $ 547.23 / Ton. The results of economic analysis with such conditions indicate that the parameters of NPV, IRR, B / C and PBP have improper values. This means that this investment is very sensitive to rising raw materials.

Open pit design and scheduling problem is a large-scale optimization problem that has attracted considerable attention during the last 45 years. With development of the mining model, a pit design tool that facilitates the best overall theoretical cash flow mining sequence through the deposit could be applied. The mine design tool is referred to in the mining industry as "Optimizer" and is based on algorithm developed by Learchs and Grossman. The development of the "know-how" to improve economics of open pit mining projects through the use of mathematical optimization techniques goes back to early 1960's. Unfortunately, up until recently, many of these "optimizing algorithms" could not be implemented due to the limited capacity of the computer hardware used in many mining operations. During the last 15 years, advancements in the computer hardware technology along with developments in software technology allowed open pit mines to have powerful desktop computers that can solve complex optimization problems on site. Western Goldfield Group Nigeria has implemented an optimization and scheduling of its coal mine using Minex Open Pit Optimizer Programme (MOPOP) to schedule their entire mine and production, resulting in significant process cost savings. This paper outlines open pit optimization techniques that were utilized in mine planning of Okobo Coal Reserve, Located in Enjema District of Ankpa Local Government Area, Kogi State, Nigeria, as a strategy to improve the economics of the open pit mining projects.

There are two approaches to view-based query processing, called query rewriting and query answering. Query rewriting is one of the most important reasoning techniques for answering queries on data represented utilizing ontologies or ontology-based data access applications. The last years a wide variety of query rewriting systems has been proposed, including the research about ontology change. In this paper, we present the discussion of the utilization of query rewriting on ontology change. We divide the use of query rewriting in this paper into 3 parts i.e. proposing a new algorithm, research development in Description Logics (DL) family and complexity of conjunctive query. Furthermore, we also present a brief description of the advantages and disadvantages of using query rewriting algorithm only on 3 types of ontology, ontology contraction, ontology evolution and ontology change. Finally, we show the list of query rewriting algorithm publication based on their approaches.

Ex-situ conservation of the Citrus has been considered as problematic and early reports have found that Citrus was a sub orthodox species and cannot be stored at low temperature. Field genebanks are difficult to maintain due to pest, disease and climate hazards. In-vitro culture methods also provide only short-term storage but this is difficult and time-consuming. For a long-term storage of plant germplasm, cryopreservation is currently the best option. Therefore a cryopreservation protocol needed to be developed to conserve Citrus germplasm for long-term. 2, 3, 5-Triphenyl tetrazolium (TTC) test was used for an assessment of cell survival after cryopreservation at 490nm. The shoot tips were encapsulated and osmoprotectant on a shaker at 100 rpm with two sucrose concentrations (0.5M & 0.75M). Subsequently, encapsulated beads were dehydrated under laminar air flow and silica gel for 6 hours. The encapsulated beads were plunged directly into liquid nitrogen for a minimum of 48 hours. Encapsulated beads were thawed at 400C for 2 minutes and rehydrated using liquid MS for 10 minutes. The beads were transferred to re-culture media optimized in experiment 2. Then cultures were kept in dark for 2 days and 1 day in semi light condition to avoid photo-oxidative stress. High viability could be seen when used mature shoots & encapsulated using 4% sodium alginate. The best condition for the encapsulation-dehydration of Citrus aurantium was obtained when beads were pretreated with the osmoprotection medium for 20 hours and dehydrated for 6 hours. Beads were pretreated with 0.75M sucrose and dehydrated under laminar air flow recorded the maximum survival (21.6%). MS medium supplemented with 2mg/l BAP was used as a re-culture medium with 56.5% survival. Finally, beads were pretreated with 0.75M sucrose and dehydrated under laminar air flow method was appropriate to cryopreservation of Citrus aurantium within the tested range.
