This paper investigates the system performance of hybrid time-power switching based relaying (TPSR) energy harvesting enabled in the multisource half-duplex relaying network over the Rayleigh fading channel. The outage probability (OP) of the proposed system model with implementing maximal ratio combining (MRC) and selection combination (SC) technique at the receiver is presented and analyzed.

This study investigated the influence of culture media and culture time on the antioxidant and α-glucosidase inhibitory activities of the methanol extract obtained from the mycobiont of Graphis handelii. Different culture media, including MIX, PDA, and SAB4%, were employed to culture the mycobiont, and the biomass was harvested during different culture periods (4, 8, and 12 weeks).

Currently, cricket farming is becoming more and more popular since it brings high economic efficiency to farmers. Crickets can be raised in a small area, are easy to care for, have a short harvest time, and have no pollution problem. This paper provides insight into the effects of three types of food on the growth and development of crickets (Gryllus bimaculatus) and proposes the rearing process of crickets.

CdTe-based quantum dots (QDs) have been used as active materials in various applications, such as sensing, imaging, and light-harvesting devices where the QDs are continuously illuminated by suitable lights. Passivation of CdTe QDs with stable inorganic layers to form core/shell or core/multiple-shell structures has been demonstrated to improve the stabilities of QDs against illumination.

In the 6G mobile networks, ensuring low latency and low energy consumption is paramount. This study explores a novel approach for addressing these issues in a backscatter communication (BC) - based multiple user unmanned aerial vehicle (UAV) - enabled mobile edge computing (MEC) Internet of Things (IoT) network.

Aquaculture, also known as aquafarming, is the farming of aquatic organisms such as fish, crustaceans, molluscs and aquatic plants.[1][2] Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish.[3] Mariculture refers to aquaculture practiced in marine environments and in underwater habitats.

The objectives of the current study are to develop a methodology to estimate the optimal size of the rainwater tank at a particular location considering the local rainfall, roof area, demand for water and the reliability of supply (supply security) required; to quantify the rainwater volume that could be harvested at site using domestic rainwater tanks to minimise pressure on the potable water supply secured from traditional catchment sources until the desalination plant is commissioned in 2013; to analyse the efficacy of rainwater tanks to reduce the stormwater runoff and improve the quali...

The aim of this thesis is investigate and design a small antenna which can be embedded onto a Polyethylene substrate (used for making roof tiles). The antenna can be used to harvest ambient energy by connecting it to a rectifier. Due to the dimensional constraints of a roof tile as well as the materials used, there are limitations imposed on the antenna size, and thus the radiation efficiency and bandwidth often become a limiting factor in the overall performance of the system.

An experiment was conducted to study the effect of edible coating and packaging material on physiological and sensory quality of litchi fruits. For this, mature litchi fruits were harvested from HRC, Patharchatta and the selected fruits were treated with Guar Gum, Xanthan Gum and Methyl cellulose (low viscosity and high viscosity)as edible coating at different concentration (0.5%, 1.0%, 2.0%, 2.5%) and stored at 4 ± 1 °C under 90 ± 5% RH.
