Laboratory experiment was carried out using ‘PKM 1’ chilli (Capsicum annuum L.) seed to standardize bioprimed seeds under moisture stress condition inorder to improve seed germination and seedling vigour. To induce the moisture stress, optimize the different concentration of water holdings capacity viz., 80, 60, 40 and 20% were used for best bioprimed seed treatment (biocontrol agents (Pseudomonas fluorescens 60% 12 h, Trichoderma viride 60% 9 h) and liquid biofertilizers (Azospirillum 10% 9 h and Phosphobacteria 15% 9h )) along with hydroprimed seed and control seed. Seed bioprimed with Pseudomonas fluorescens 60% for 12 h improved the germination percentage ( 82), root length (14.2 cm), shoot length (6.2 cm), dry matter production (0.0489 g 10 seedlings-1) and vigour index (1673) compared to control seed. Seed biopriming with  Pseudomonas fluorescens 60% for 12 h can be adopted to improve seed germination and seedling vigour under moisture stress condition upto 20%.

Current Journal of Applied Science and Technology, Page 1-7
DOI: 10.9734/cjast/2019/v34i330129

In this study, we propose a hybrid Question Answering (QA) system for Arabic language. The system combines textual and structured knowledge-Base (KB) data for question answering. It make use of other relevant text data, outside the KB, which could enrich the available information. The system consists of four modules. 1) a KB, 2) an online module, and 3) A Text- to-KB transformer to construct our own knowledge base from web texts. Using these modules, we can query two types of information sources: knowledge bases, and web text. Text-to-KB uses web search results to    identify question topic entities, map question words to KB predicates, and enhance the features of the candidates obtained from the KB. The system scored f-measure of .495 when using KB. The system performed better with f-measure of .573 when using both KB and Text-to-KB module. The system demonstrates higher performance by combining knowledge base and text from external resources.

Current Journal of Applied Science and Technology, Page 1-17
DOI: 10.9734/cjast/2019/v34i330130

The study utilized the exhaust gas from a diesel engine to preheat water in the constructed shell and tube heat exchanger.

The theoretical analysis of the heat exchanger was carried out using the Log Mean Temperature Difference (LMTD) method. The Volumetric flowrate of the water was manipulated using a valve and the resulting output temperature of water leaving the heat exchanger was recorded. Experimentation was carried out to determine the effects of volumetric flow rate on the output temperature and the effectiveness of the heat exchanger. After the test and data analysis, it was discovered that that at flow rate of 3.0 Liter per minute (LPM) the effectiveness of the heat exchanger was peak at 43.34%. The volumetric flow rate of water is inversely proportional to the output temperature of water and it was also established that the effectiveness of the heat exchanger depends on output temperature of and the mass flow rate of the water. Also it was proven that by preheating water before it enters the boiler of the Rankine cycle the efficiency of the cycle increases.

DOI: 10.9734/cjast/2019/v34i330131

This paper examines the concept of reorder point model of an inventory in an imperfect manufacturing system. The essence of the study is to know the point at which manufacturing firms should place an order for their raw materials. A model is developed which addresses the availability of raw materials in cases of variable demands and variable production lead times. The numerical data of innoson and bodex firm were obtained and used in testing the validity and robustness of the model. The result also showed the quantity to reorder provided the service level of the firm is known. This raw materials are made available via this model developed before manufacturing processes starts so as to avoid zero or excess stock. During production, defective items are produced with finished goods and as such rework process is necessary to convert those defectives into finished goods or products. Finally, this research is recommended for manufacturing industries in Nigeria for optimum performance.

The aim of this study was to investigate the effects of land degradation on agricultural land use, planning and management in Kalama Division, Machakos County; and specifically determined farmers’ considerations of land suitability for selected types of agricultural land uses in varying cropping zones, investigated farmers’ local environmental knowledge of land degradation indicators and finally documented farmers’ land management strategies and practices for soil and water conservation. Data was collected using a questionnaire, along a road transect cutting across upper, middle and lower zones (parts) of a slope. A total of 40 households along the transect on the three zones were interviewed. Results obtained revealed that crop farming, livestock, poultry, farm forestry and bee keeping were the major agricultural land use activities carried out in the study area. Overall, steep slope was the most important factor considered for farm forestry (17%) (5.29 STDEV). Bee farming was the least land use practice accounting for only 1% of total land use. Most land degradation (15%) was reported in the middle zone while lowest land degradation (7%) was reported in the upper zone. The study found out that most households were aware of land degradation indicators in their local environment and described them using their indigenous environmental knowledge. The smallholder farmers prevented further land degradation by use of their local or traditional ways such as application of organic manure, planting of trees, crop rotation, use of gabions and stone lines. Different zones had different land use and management practices due to differences in terrain and other physical and biophysical characteristics. Overall, the major land management practices included tree planting (23%) (4.04 STDEV) and water conservation and gabion making (10%) (2.52 STDEV). This study clearly established an existence of smallholder farmers’ indigenous knowledge, perceptions, and beliefs of the local environmental factors of land condition which are necessary for the farmer’s decision-making on land use planning and management. On the basis of these findings, the study argues for place-based analysis and understanding of the landscape structure and local micro-environments in enhancing understanding of local-level decision-making on land use planning and management by smallholder farmers in maintaining livelihood security. Even though the study is limited to the local scope, it can provide a basis for designing policies aimed at rural livelihood security improvement and inform and facilitate targeting of outside interventions such as land use planning and management programs which can be built on existing indigenous knowledge.

Wireless Sensor Networks (WSNs) are networks of small, cheap, independent battery-powered sensor nodes, finds applications in agriculture, health care, intrusion detection, asset tracking, habitat monitoring and in many other fields.

It is sometimes necessary to disseminate data via wireless links after the deployment of sensors so as achieve the objectives of sensors configurations parameters adjustment or distribution of commands management and queries to sensors. The present study considered how Shortest Path Minded Sensor Protocols for Information via Negotiation (SPIN)-Recursive (SPMS-Rec), reduces the energy dissipated in the event of failures by requiring intermediate relay nodes to try alternate routes, is suitable for data dissemination. Despite to the power constraints and memory limitations of sensory nodes, ‘Instantly Decodable Network coding’ (IDNC) was considered because of its practicality, relevance and numerous desirable properties such as instant packet recovery, simple XOR-based packet encoding and decoding, and zero buffer memory to store un-decoded packets. The paper concludes with reference and suggestions of possible future research areas.

We are interested by studying the influence of two drying methods: in the shade and solar energy, on phytochemical composition. For this, we choose the rhizomes of the plant Equisetopsida Asterales, a species that can be found in the poor soil of Provence and Corsica. It prefers dry, sunny places in the Mediterranean. It is native to Southwest Asia, the East and spread in North Africa (Algeria, Morocco, Tunisia, Libya), Australia and the Americas, and Europe (Greece, Italy, France, Portugal, Spain). Equisetopsida Asterales rhizomes are used in Algeria as a traditional cream, which contributes to the disappearance of scars generated by burning. The antimicrobial properties of medicinal and aromatic plants have been known since antiquity. However, it was not until the early 20th century that scientists are beginning to show interest. It is known that the treatment of microbial infection is mainly based on the use of antibiotics, several work is devoted to the study of the antimicrobial power of essential oils.

After some experiences in this work, the important result was obtained, time of Equisetopsida Asterales by solar energy is better than shade; and yield of essential oil extracted is better from the rhizomes dried by solar energy.
