Modelling climate change impact and mitigation actions: a case study of rice productivity in West Africa based on panel data analysis

This paper investigated how climate change can affect paddy rice productivity and proposed a mitigation measure that may be undertaken. The analysis first explores the potential impacts of climate variables on rice yields by using panel data covering the period 1980-2016 for seven countries members of the West African Economic and Monetary Union (WAEMU). It then went on to calculate the investments needed in R&D for...

Path analysis for the evaluation of climate variables on Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) development phases in tomato crop

The objective of this study was to evaluate the influence of climatic variables on the population dynamics of the tomato moth Tuta absoluta (Meyrick, 1917), (Lepidoptera:Gelechiidae) through correlations and path analysis, discovering their effects on the main variable in organic and conventional tomato crops (Solanum lycopersicum L.; Solanaceae). We studied the effects of the pheromone on insect phase sampling in two...

Linear and nonlinear properties of heartbeat time series in obesity

In previous studies, the property of ‘complexity’ was suggested as a systemic profile of a human cardiovascular system. A loss of complexity in heartbeat time series is a significant bio-marker for assessing the aging and dysfunctions of a cardiac system. In different approaches by phase-rectified signal average (PRSA), a low deceleration capacity (DC) in heart rate variability (HRV) demonstrated a high risk of cardiac...

Interaction of salicylic acid and fungi on polyphenols compounds in chickpea seedling

The present study was carried out to evaluate beneficial effect of low level of exogenous salicylic acid (SA) treatment on different response of chickpea (Cicer arietinum L) cultivars, under biotic stress effects seedling stage. In this frame, seeds of chickpea cultivars (ILC 3279) were treated with a range of salicylic acid concentrations (0.05 and 0.5 mM) and subjects to Fusarium oxysporium f. sp. ciceris for eight...

Comparison of network topologies of time series in different frequencies

Complex network theory has stimulated the study of complexities in various kinds of fields. By the algorithm of visibility graph, weekly and daily time series of Shanghai stock index was converted into networks to analyze their characteristics. The overall properties of networks remain similar, while details are different with different levels of details provided by different frequency data. The findings provide evidences...

Bacteriophages and phage products: Applications in medicine and biotechnological industries, and general concerns

Since their discovery in 1928 antibiotics have transformed medicine and saved millions of lives; however, the current global appearance of antibiotic resistance and absence of new antibiotics commercialization to the health sector return to the post-antibiotic era. Today, scientists are working to revive a century old technique of using bacteriophage as an option to currently available antibiotics in management of...

Evaluation of a local petroleum cement for oil well cementing operations in Algeria

The cementing of oil wells is done using special cement called Class G cement, whose properties meet the requirements of the American Petroleum Institute (API). Although cements are not the ideal material for good sealing in drill holes, there is currently no alternative material available. Algeria, which ranks high among the oil and gas producing countries, has recently begun production of petroleum cement. The aim of...

Metal contamination characteristics of water bodies in Ilaje, a riverine community of Ondo State, Nigeria

The study investigated the impact of pollution on surface water bodies in Ilaje area of Ondo state. Water-ways in four communities, namely, Araromi, Ayetoro, Igbokoda and Ugbonla located within Ilaje were selected for the study with the specific aim of establishing information on the metal contamination characteristics of the water bodies. Water samples were collected along the waterways from three sampling points per...

Heavy metal studies of commonly consumed food crops (maize, sorghum, potato, yam and cassava) in southwestern Nigeria

Heavy metal accumulation in soil is of concern in agricultural productions due to its adverse effect on food quality and crop growth. This study, therefore, examines the heavy metal concentrations of some commonly consumed foods collected in some parts of southwestern Nigeria. Five food samples (potato, sorghum, maize, yam and cassava) were collected from five different locations and analyzed for metals using standard...

Comparative performance evaluation of different animal drawn improved seeding equipment for black gram under terrace condition-A case study of Sikkim, India

The black gram in Sikkim is sown in 5960 ha with average yield of 880 kg-ha-1. The sown area (2410 ha) of black gram is maximum in west Sikkim (Gyalshing) district. The black gram sowing (manual practice of broadcasting of seeds) is mostly done in July-August in terraces of Sikkim. The two row animal drawn improved zero till seed drill (weight: 23.7 kg, unit price: Rs. 2700, overall dimension: 730 * 940*735 mm) was tested...

Solar energy and food preservation in Nigeria

As the world population increases geometrically, world food production is not sufficient in meeting the demand of the ever increasing population. Africa is not left out in the increase in food demand, especially Nigeria being the most populous African country. Most times, it is not that food is not available, but how well are we able to preserve the ones available so that they do they perish. Most food preservation methods...
