Abstract White Guinea yam ( Dioscorea rotundata Poir.) is indigenous to West Africa, a region that harbours the crop's tremendous landrace diversity. The knowledge and understanding of local cultivars’ genetic diversity are essential for properly managing resources, conservation, sustainable use their improvement through breeding. This study aimed dissect phenotypic molecular white cultivars fr...

This study aimed to compare the diversity of birds between protected and non–protected areas that are similar in climatic geographical features. The was carried out three different habitat types (Forest, Agricultural land Wetland Sundarijal Non-protected Changunarayan. Field data were collected using a “Point Count Approach” transects which laid & Wetland). Shannon-Wiener Margalef Diversity...

Building inland waterways affects the natural structure, formation, and extent of riverbed riparian zone. It alters hydrology sediment deposition conditions hence damages aquatic ecosystem. To address effects construction on riverine biome, benthic macroinvertebrate communities were compared at different building stages along a gradient shipping traffic density two montane rivers in China. The ...

Butterflies are considered bioindicators of a healthy and diversified ecosystem. Endosulfan was sprayed indiscriminately on large plantations in the Rewa district Madhya Pradesh, causing serious threat to In this study, we surveyed butterflies for their abundance diversity three areas differentially affected by endosulfan, i.e., Govindgarh-highly area, Jayanti Kunj-moderately Kothi Compound-una...

Phlebotomine sandflies were captured in rural settlement and periurban areas of the municipality of Guaraí in the state of Tocantins (TO), an endemic area of American cutaneous leishmaniasis (ACL). Forty-three phlebotomine species were identified, nine of which have already been recognised as ACL vectors. Eleven species were recorded for the first time in TO. Nyssomyia whitmani was the most abu...

In this paper, the use of the MaxInf Principle in real optimization problems is investigated for engineering applications, where the current design solution is actually an engineering approximation. In industrial manufacturing, multibody system simulations can be used to develop new machines and mechanisms by using virtual prototyping, where an axiomatic design can be employed to analyze the in...

Methods are described for extracting the trend from an economic data sequence and for isolating the cycles that surround it. The latter often consist of a business cycle of variable duration and a perennial seasonal cycle. There is no evident point in the frequency spectrum where the trend ends and the business cycle begins. Therefore, unless it can be represented by a simple analytic function,...

Abstract. Proportional-integral-derivative (PID) control is the most popular control architecture used in industrial problems. Many techniques have been proposed to tune the gains for the PID controller. Over the last few years, as an alternative to the conventional mathematical approaches, modern metaheuristics, such as evolutionary computation and swarm intelligence paradigms, have been given...
