Ever wondered why bread rises? Or why dough needs to rest? From cakes and biscuits to flat breads and standard loaves, the diversity of products is remarkable and the chemistry behind these processes ...is equally fascinating. The Science of Bakery Products explains the science behind bread making and other baked goods. It looks at the chemistry of the ingredients, flour treatments, flour testing and baking machinery. Individual chapters focus on the science of breads, pastry, biscuits, wafers and cakes. The book concludes with a look at some experiments and methods and goes on to discuss some ideas for the future. The Science of Bakery Products is an interesting and easy to read book, aimed at anyone with an interest in everyday chemistry.

Additionally, fuel treatments on federal lands still fail to address the most important areas in the WUI: the immediate surroundings of individual homes on private land. ...despite increased focus on these treatments, these policies likely will achieve few of their intended results. ...the resource use argument ignores important economic and ecological considerations that would prevent it from succeeding.
While the Healthy Forests Restoration Act (HFRA) and Consolidated Appropriations Act of 2018 seek to address the problem by directing funds toward fuel treatment in the WUI and streamlining National ...Environmental Policy Act (NEPA) review processes in WUI areas, this is not enough. The public debate around fire too often leaves out the impact of the WUI and focuses on the past and present policies of the federal government-in particular, its early efforts to increase timber production and eradicate wildfire on public lands for most of the 20 th century and its shift over the past 30 years to decrease logging while allowing some fires to burn. ...the resource use argument ignores important economic and ecological considerations that would prevent it from succeeding.

The oxygen consumption rate of CF1 male mice was determined before, during, and after sham- and microwave-irradiation at environmental temperatures of 20 degrees C, 24 degrees C, 30 degrees C, and 35 ...degrees C, relative humidity of 55%, and air flow rate of 78 ml/min. Five forward power levels ranging from 0.09 to 3.3 W, which resulted in corresponding average dose rates ranging from 1.2 to 45.1 mW/g were used. The values of the oxygen consumption rate were converted to those of the specific metabolic rate (SMR). The result indicates that with high levels of microwave dosing (greater than 10 mW/g) the specific metabolic rate of mice decreased in some cases, in the environmental temperatures of 20 degrees C and 24 degrees C. However, the decreased SMR values were not lower than the SMR values of the sham-irradiated group in 30 degrees C. In the case of 35 degrees C, the high level dosing with microwave radiation caused increases in the SMR value over the sham value. A possible trend towards increased SMR value during and after irradiationwith low level (1.6 mW/g) microwave radiation in the environmental temperatures of 24 degrees C and 30 degrees C suggests further experiments with low level microwave radiation to determine possible effects of low level microwave radiation in stimulating increases in specific metabolic rate.
A right circular cylindrical cavity designed to resonate at 380 MHz was developed to irradiate a monkey head with little or no radio frequency exposure to other tissues. The system is used in studies ...of the behavioral effects of the absorption of radiant power. Dose-rate measurements were made with an electrically equivalent calorimetric load, consisting of a saline-filled plastic cylinder whose geometry and position in the cavity reproduced cavity and transmission line parameters measured with a test animal. Since integral dose rate P/sub m/ (total power absorbed) is proportional to the net power transmitted to the cavity P/sub t/ the constant of proportionality K/sub m/= P/sub m/ / P/sub t/ must account for the absorption of field energy by the tissue. K/sub m/ was determined by comparing the temperature rise produced in a fixed time period by the dissipation of dc power to the temperature rise produced by RF radiation in the same time period. It was found that, at an ambient temperature of 25/spl plusmn/2/spl deg/C and a relative humidity of 55 /spl plusmn/ 5 percent, K/sub m/ was 0.62.
