Low-intensity pulsed ultrasound (LIPUS) is a promising therapy that has been increasingly explored in basic research and clinical applications. LIPUS is an appealing therapeutic option as it is a noninvasive treatment that has many advantages, including no risk of infection or tissue damage and no known adverse reactions. LIPUS has been shown to have many benefits including promotion of tissue healing, angiogenesis, and tissue regeneration;inhibition of inflammation and pain relief;and stimulation of cell proliferation and differentiation. The biophysical mechanisms of LIPUS remain unclear and the studies are ongoing. In recent years, more and more research has focused on the relationship between LIPUS and stem/progenitor cells. A comprehensive search of the PubMed and Embase databases to July 2020 was performed. LIPUS has many effects on stem cells. Studies show that LIPUS can stimulate stem cells in vitro;promote stem cell proliferation, differentiation, and migration;maintain stem cell activity;alleviate the problems of insufficient seed cell source, differentiation, and maturation;and circumvent the low efficiency of stem cell transplantation. The mechanisms involved in the effects of LIPUS are not fully understood, but the effects demonstrated in studies thus far have been favorable. Much additional research is needed before LIPUS can progress from basic science research to large-scale clinical dissemination and application.

This paper describes a freely-available spread-sheet that has been developed to simulate the conditions of reaction rate, core acceleration and velocity, energy generation, and pressure within a detonating fission-bomb core. When applied to a model of the Hiroshima Little Boy bomb, the spreadsheet predicts a yield of 12.7 kilotons, a figure in reasonable agreement with published values.

Frontiers of History in China 2018年第2期13卷 259-264页

作者： Christopher A. reed The Ohio State University

Shuge Wei＇s News Under Fire is a fascinating, intricate, and well-written addition to scholarship on Republican China＇s print-based media, Nanjing Decade （1928-37） party politics and institution building, and Sino-Japanese diplomacy, propaganda, and war. Only rarely does a book appear that changes the reader＇s long-held beliefs about one topic, much less three. News Under Fire is such a book. Persuasively influenced by multiple English- and Chinese-language historiographies, the core of this book is grounded in Wei＇s own painstaking research in some fifteen archives, twenty-six newspapers and journals, and many libraries.

Canopy air curtain （CAC） technology has been developed by the National Institute for Occupational Safety and Health （NIOSH） for use on continuous miners and subsequently roof bolting machines in underground coal mines to protect operators of these machines from overexposure to respirable coal mine dust. The next logical progression is to develop a CAC for shuttle cars to protect operators from the same overexposures. NIOSH awarded a contract to Marshall University and J.H. Fletcher to develop the shuttle car CAC. NIOSH conducted laboratory testing to determine the dust control efficiency of the shuttle car CAC. Testing was conducted on two different cab configurations： a center drive similar to that on a Joy 10SC32AA cab model and an end drive similar to that on a Joy 10SC32AB cab model. Three different ventilation velocities were tested-0.61, 2.0, 4.3 rrds （120, 400, and 850 fpm）. The lowest, 0.61 m/s （120 fpm）, represented the ventilation velocity encountered during loading by the continuous miner, while the 4.3 m/s （850 fpm） velocity represented ventilation velocity airflow over the shuttle car while tramming against ventilation airflow. Test results showed an average of the dust control efficiencies ranging from 74 to 83% for 0.61 m/s （120 fpm）, 39%-43% for 2.0 m/s （400 fpm）, and 6%-16% for 4.3 m/s （850 fpm）. Incorporating an airflow spoiler to the shuttle car CAC design and placing the CAC so that it is located 22.86 cm （9 in.） forward of the operator improved the dust control efficiency to 51%-55% for 4.3 m/s （850 fpm） with minimal impact on dust control efficiencies for lower ventilation velocities. These laboratory tests demonstrate that the newly developed shuttle car CAC has the potential to successfully protect shuttle car operators from coal mine respirable dust overexposures.

Testing was completed on an earlier roof bolter CAC that used slots to provide a perimeter airflow. NIOSH tested it due to its unique design that differed from canopies that provided uniform airflow. Based upon NIOSH recommendations from the earlier testing, a 3rd generation roof bolter CAC has been developed by J.H. Fletcher & Co. The changes to this CAC involve design modifications to the plenum outlets, using a single row of outlets on the perimeter and a different material for the plenum. This laboratory testing was a continuation of the original perimeter slotted CAC design. Using gravimetric and instantaneous sampling of respirable dust concentrations underneath and outside of the CAC. the laboratory testing was completed using three different blower fans that delivered differing airflows. The maximum plenum airflow velocities ranged from 2.34 to 3.64 m/s (460-716 fpm). Results showed plenum respirable dust concentrations ranging from 34.6% to 49.3% lower than respirable dust concentrations outside the plenum protection zone, thus showing an improvement in protection for the roof bolter operators.

Agricultural land has conventionally been perceived primarily as a production factor. For this reason the highest and best use （HBU） of such land was considered to be agricultural production for income purposes. The transition towards a multifunctional agricultural land market, where alternative uses--such as for lifestyle purposes--is evident, has challenged this view. Lifestyle buyers of farms often focus on a variety of characteristics of agricultural land which are not necessarily related to income but usually more intangible and subjective, which pose a measurement problem for valuers. The continued use of familiar traditional farming characteristics when valuing agricultural properties where lifestyle motivations are present, and the exclusion of less measurable characteristics, means that the market sales comparison method cannot be executed accurately. This study used a mixed methods research strategy to determine whether valuers use characteristics mainly related to agricultural production as HBU in valuations of agricultural properties bought for lifestyle purposes, and to identify the value attributes of farms that attract lifestyle buyers （and whether these differ from production oriented buyers）. This was done in an intensive and extensive agricultural area within the Western Cape Province of South Africa. Results indicate that valuers use familiar production related characteristics when valuing farms bought for lifestyle purposes, while lifestyle and production oriented buyers also interpret the value attributes of agricultural properties differently. For this reason a multiple perspective approach to agricultural land valuations where the HBU is uncertain is proposed.
