Road dust can degrade agricultural produce, affect health, reduce road safety, increase wear and tear on vehicles, and increase the rate of deterioration of the roadway. In October 1996, Australian Road Research Board Transport Research completed and published a study of various dust-control techniques. That report encompassed a worldwide literature search on various measures to control dust and a survey of municipal councils and other road authorities across Australia and New Zealand to ascertain what experiences people have had with the use of dust suppressants. The outcome of this study is to provide a guide to the reported effectiveness of particular dust suppressants under given circumstances and other methods to better control dust emissions.

Context: Recently, the incidence and prevalence of multiple sclerosis (MS) have increased drastically in different regions of the world, including Asia. The present study aimed to systematically review the recent MS epidemiology in Asia, New Zealand, and Australia. Methods: A systematic literature search was performed in Medline and Embase databases to retrieve the available studies regarding MS epidemiology in Asia, New Zealand, and Australia. Results: Most of the studies were performed in hospital settings. The female-to-male ratio in the sample populations varied from 1.5:1 in Turkey to 5:1 in Malaysia. The total mean age at the onset of MS varied from the minimum of 28 years in Hong Kong to the maximum of 36 years in the United Arab Emirates. Among 16 pertinent studies in this regard, seven addressed the incidence rate of MS, and 13 addressed the prevalence of the disease. The highest prevalence rate was reported to be respectively 124.2 and 148.06 in Australia and Iran versus 2.73 in Malaysia (06 per 100,000 population), while a higher incidence rate was estimated at 6.88 and 6.7 per 100,000 population in Kuwait and Australia, respectively compared to the lower incidence rate per 100,000 population in China (0.2 in females, 0.12 in males). Conclusions: According to the results, the prevalence of MS has increased in Asia, while the prevalence of MS in this continent is lower compared to the rates reported in Australia, Europe, and North America.

Dust pollution is a key issue that contractors ought to address in the sphere of sustainable construction. Governments on behalf of the public assume part of the responsibilities for minimizing dust emissions on construction sites. However, the measures that are useful for governments to fulfill such a responsibility have not been explored explicitly in previous studies. The aim of this research is to map out China’s practices in this area with the intention of filling the knowledge gap. Using a combination of research methods, five categories of governmental measures are proposed: technological, economic, supervisory, organizational, and assessment-based. Data from 37 major cities in China are collected for analysis. While the proposed categories of measures are demonstrated in China, the data analysis results show that governments prefer technological and organizational measures, and institutional guarantees and technological innovation are a prerequisite for dust-free construction. This research provides a comprehensive examination of construction dust control from the perspective of governments, and it can assist governments in improving the performance of dust management in the construction context.

The most important losses in agricultural production which involve the greatest costs on the farm economy occur postharvest. It is estimated that worldwide between 10 and 40% losses of agricultural produce occur postharvest. Losses are more severe in developing than developed nations of the world. Several species of fungi and in some cases bacteria participate in postharvest deterioration and rots of tubers and agro- produce. These include species of Aspergillus, Fusarium, Colletotrichum, Macrophomina, Penicillium and Rhizopus amongst several others. In a bid to control these storage diseases several control techniques including physical, biological, and chemical and in recent times plant-based pesticides are employed. Chemical control has been identified as the most popular and most effective means of controlling plant diseases. However, it is being de-emphasized due largely to mammalian toxicity occasioned by chemical residues in crops. This in addition to many other demerits on ecological health and build-up of pathogens’ resistance to some of the most effective fungicides have prompted search for alternatives. Recently in plant pathology many tropical plants are being screened for fungitoxic properties. This review presents highlights of the different control techniques for control of myco- induced storage rots of tubers and agricultural products in the tropics.
