Crop pests and diseases are ranked as some of the world’s leading threats to agricultural productivity. The need to improve adoption of digital solutions prompted a review on the applicability of emerging digital solutions in large-scale surveillance of crop pest and diseases. This study presents findings on key requirements for achieving digitized large-scale pest surveillance, fitness for purpose of common autonomous biosecurity surveillance technologies, and prospects of smartphones as an alternative surveillance solution. Firstly, the research identified appropriateness of the solution, availability of supporting infrastructure and level of stakeholder involvement in solution formulation as some of the key determinants of digital solution adoption. Although most common autonomous biosecurity surveillance technologies are promising, their adoption in developing nations are limited by operational costs, legal requirements, skillsets, and operational environments among others. Thirdly, recent advancements in smartphones and wide spread ownership among farmers provide a unique opportunity for advancing Mobile Crowd-Sensing solutions in achieving large-scale pest surveillance. Lastly, we recommend designing an incentive mechanism to motivate farmers’ participation in a surveillance solution.

The presence of aliphatic hydrocarbons in sediments at the bottom of the platform and the continental margin of the northeastern tip of the Antarctic Peninsula and its natural escapes, leads us to infer about the likely effects they may have on the Antarctic environment, particularly on changes off average in surface temperatures and seawater. Methane leaks recorded in shallow waters of the region are compatible with the destabilization of gas hydrates in the marine substrate and with changes in average surface temperatures and seawater, suggesting a probable environmental impact such as a consequence of this process, based on the hypothesis of the “clathrate rifle”, the scientific theory of Gerry Dickens and James Kennet, which argues that the rise in sea temperature can lead to a sudden release of methane from the clathrate deposits located in the ocean bottoms, as happened in the Eocene.

We present the energy bands and the DOS, the forbidden energy and total energy of the crystalline compound of AlAs, calculated with the LMTO orbital method within the framework of density functional theory (DFT). Se solved the Schrödinger equation with a potential in the local density approximation (LDA) that uses the Barh-Hedin approximation for the term exchange and correlation. Potential calculated with a small homogeneous fraction of electron charge in the empty spheres and an electronic charge similar to that of the free atom in the atomic spheres of the crystal lattice. The structure of the energy bands presented an indirect forbidden energy gap of 0.160Ry or 2.18 eV with a minimum total energy of -18.10 Ry that fit well with the experimental results
我们介绍了在密度泛函理论(DFT)框架内用 LMTO 轨道法计算的 AlAs 晶体化合物的能带和 DOS、禁能和总能。Se 利用局部密度近似(LDA)中的电位求解了薛定谔方程,该近似使用巴赫-海丁近似来计算交换和相关项。计算时,空球中的电子电荷只占很小的均质部分,而晶格原子球中的电子电荷与自由原子的电子电荷相似。能带结构呈现出 0.160Ry 或 2.18 eV 的间接禁止能隙,最小总能量为 -18.10 Ry,与实验结果非常吻合。
