Many countries promote food security through agricultural policies to boost productivity without looking at the effect of such on sustainability. This study investigates and land ownership adoption sustainable practices in Nigeria. A structured questionnaire was used for data collection from a survey 288 smallholder farmers November 2018. The results Logistic Regression Model revealed that prog...

There are many useful cryptographic schemes, such as ID-based encryption, short signature, keyword searchable encryption, attribute-based encryption, functional encryption, that use a bilinear pairing. It is important to estimate the security of such pairing-based cryptosystems in cryptography. The most essential number-theoretic problem in pairing-based cryptosystems is the discrete logarithm ...

The 1986 Chernobyl fallout had dramatic consequences for traditional reindeer husbandry in central and southern Norway, and also for many farmers in these areas. In end July 1986 the Government therefore passed a principal resolution stating that every producer should be economically compensated for all losses due to measures introduced by the authorities because of the Chernobyl deposition. By...

Ferrofluids (FFs) are stable colloidal suspensions composed of single-domain magnetic nanoparticles dispersed in a carrier liquid. And it is an intelligent material, exhibiting normal liquid behaviour coupled with superparamagnetic properties. Since the properties and the location of these fluids can easily be influenced by a magnetic field, FFs have recently attracted many scientific, industri...

In this paper we estimate the welfare associated with the Medicare HMO program, now known as Medicare+Choice. We find that the Medicare HMO program contributed over $5.8 billion (1998 dollars) to consumer and producer surplus from 1993 to 1998. We estimate that the HMO program generates positive net societal welfare as long as the cost of treating HMO enrollees in the Medicare fee-for-service (...

plant tissue culture refers to growing and multiplication of cells, tissues and organs of plants on defined solid or liquid media under aseptic and controlled environment. micropropagation allows rapid production of high quality, disease-free and uniform planting material. the micropropagation of high quality planting materials of ornamentals, and forest and fruit trees has created new opportun...

In recent years, precision agriculture (PA) has become an important issue in agriculture. Wireless sensor networks (WSNs) might be a great tool to monitor plant growth in greenhouses, because they can provide spatiotemporal sensing data converted from real world physical/analog signals with high-resolution. In Taiwan, there are many small contracting greenhouse producers who operate their busin...

PURPOSE To determine the relationship between the American Medical Association's (AMA) functional vision score (FVS) and vision-specific quality of life in retinitis pigmentosa (RP) patients using the National Eye Institute's Visual Functioning Questionnaire (NEI-VFQ 25). METHODS One hundred eight patients with RP participated in the study. We measured best-corrected visual acuity, conducted ...
