A huge gas explosion occurred on 13 June 2021 in Shiyan City, China, resulting in 25 casualties and serious injuries to 37 people. The main victims of this explosion were stall keepers and customers buying breakfast and fresh vegetables in the food market. There is a continuous need to enhance the understanding of such unfortunate events, given the dangers they pose. This study analyzes the causes of this accident considering the general background and scenes of the explosion, and then describes the rescue operations undertaken. The investigation results revealed that the explosion was caused by the poor maintenance of gas facilities and negligence of safety regulations. It is, therefore, recommended that the control of these two main aspects be strengthened to reduce the recurrence of such unfortunate accidents.

Nowadays, people worldwide are leading to fast lifestyles due to their official work and childrens’ education. The situations compel almost every earning member who does not have enough time to buy fresh vegetables and other essential food ingredients for cooking good foods both in the lunch and dinner at home. For the last two decades, mainly office goers are dependent on convenience foods called ready-to-eat foods. Disposable income, taste preferences, working stress, and psychological tenacity are the significant factors of the growing demand for fast food or ready meals among the middle-class urban population. Recent trend shows that the global convenience food market is expected to reach a 4.4% compound annual growth rate at the end of 2025. India is also supposed to be a significant contributor among other developed countries. The country is expected to reach the compound annual growth rate (CAGR) tentatively 17%-19% (approximately $655 million) by 2025. Small-scale industries (SSI) play significant roles by engaging themselves with excellent investment in the convenience food market. The increasing demand for food products is the main reason sourced from the millions of consumers worldwide. Hence

AbstractMany people living in Mwanza, Tanzania, provision themselves through urban agriculture—the planting of crops and raising of animals in urban and peri-urban areas, as well as in the countryside. This article compares Mwanza's urban farmers with those in Kenya, Zambia, Zimbabwe and Ghana. Like Zimbabwe's urban agriculturalists, more and more of Mwanza's are not among the poorest of the poor. Much like Ghana's urban farmers, those in Mwanza are often middle and upper-class males with access to scarce land and inputs. Urban cultivators in Mwanza differ from those in Kenya and Zambia with regard to gender, socio-economic class and the factors motivating their farming activities. These findings suggest that even though socio-economic differentiation is on the increase in Tanzania it has not reached the levels of divergence found in Kenya and Zambia. Many of Mwanza's wealthier males continue to face enough job/income insecurity to choose to plant crops to support themselves and their household in lean times. They may also engage in urban agriculture because they are unable or unwilling to take advantage of more profitable investment opportunities outside the food market, or because they desire to spread risk across a number of different investments.

Even though many early workers had suggested the use of lower voltages to increase topographic contrast and to reduce specimen charging and beam damage, we did not usually operate in the conventional scanning electron microscope at low voltage because of the poor resolution, especially of bioligical specimens. However, the development of the “in-lens” field emission scanning electron microscope (FESEM) has led to marked inprovement in resolution, especially in the range of 1-5 kV, within the past year. The probe size has been cumulated to be 0.7nm in diameter at 30kV and about 3nm at 1kV. We have been trying to develop techniques to use this in-lens FESEM at low voltage (LVSEM) for direct observation of totally uncoated biological specimens and have developed the LVSEM method for the biological field.

A number of papers have appeared recently which purport to have carried out x-ray microanalysis on fully frozen hydrated samples. It is important to establish reliable criteria to be certain that a sample is in a fully hydrated state. The morphological appearance of the sample is an obvious parameter because fully hydrated samples lack the detailed structure seen in their freeze dried counterparts. The electron scattering by ice within a frozen-hydrated section and from the surface of a frozen-hydrated fracture face obscures cellular detail. (Fig. 1G and 1H.) However, the morphological appearance alone can be quite deceptive for as Figures 1E and 1F show, parts of frozen-dried samples may also have the poor morphology normally associated with fully hydrated samples. It is only when one examines the x-ray spectra that an assurance can be given that the sample is fully hydrated.

Computer synthesized vowels of 50- and 300-ms duration were presented to normal-hearing listeners at a moderate and high sound pressure level (SPL). Presentation at the high SPL resulted in poor recognition accuracy for vowels of a duration (50 ms) shorter than the latency of the acoustic stapedial reflex. Presentation level had no effect on recognition accuracy for vowels of sufficient duration (300 ms) to elicit the reflex. The poor recognition accuracy for the brief, high intensity vowels was significantly improved when the reflex was preactivated. These results demonstrate the importance of the acoustic reflex in extending the dynamic range of the auditory system for speech recognition.
