Coke oven, which is a large industrial furnace, is complex in structure. A two-dimensional structure diagram can hardly help one observe the inner structure of a coke oven or master its working principle comprehensively. In order to solve this problem, a complete 3D digital model of a coke oven is generated by assembling the three-dimensional models of coke oven components created with SketchUp...

Two experiments were conducted to evaluate whether fermentation end products in silage affect intake and digestion in beef cattle. Six rumen-cannulated Nellore steers were randomly assigned to a replicated 3 × 3 Latin square design with 14-d periods. Each period consisted of 9 d for adaptation and 5 d for sample collection. Steers were housed in a tie-stall barn and individually fed once daily ...

The door to a microwave oven forms part of the heating cavity, allowing access to the oven interior. The seal around the door is never perfect, so electromagnetic fi elds will leak out of the oven, potentially interfering with other electrical equipment or exceeding safety limits for power levels in human operators. Oven designs have to meet legal requirements for the amount of power which can ...

The authors report on a rubidium atomic magnetometer designed for use in a shielded environment. Operating in the spin-exchange relaxation-free regime, the magnetometer utilizes parametric modulation of the z-magnetic field to suppress noise associated with airflow through the oven and to simultaneously detect x- and y-field components, using a single probe beam, with minimal loss of sensitivit...

The aim of the study was to evaluate the efficiency of an ultrasonic pretreatment at different amplitudes and extraction times, on the content of antioxidant compounds (phenolics, anthocyanins, ascorbic acid) and total antioxidant capacity of black currant fruits. Additionally, the influence of sample preparation (frozen storage/drying) was evaluated. Extraction was performed in 60% ethanol wit...

Grapefruit (Citrus paradisi Macf.) is an important cultivar of the Citrus genus which contains a number of nutrients beneficial to human health. The objective of the present study was to evaluate changes in bioactive flavonoids, antioxidant behaviour, and in vitro cytoprotective effect of processed white and pink peels after oven-drying (45°C-60°C) and freeze-drying treatments. Comparison with ...

The vacuum oven-drying method (60#{176}C) was compared with the freeze-drying method. By the former method, 72.85 ± 0.0374 (SD) % moisturewas removed, by thelatter, 81.04 ± 0.050%.The feces were from the same source. With the freeze-drying method total moisture removed is clearly greater, and the time required was only 16 h, as compared with 48 h required by the vacuum oven-drying method. There...

Decoction of Kampo medicines plays an important role in clinical practice, especially in individualized treatment, while the inconvenience and a long time requirement of the decocting process are impediments to its widespread use in Japan. In this study, we improved the decocting method by using a microwave oven such as those found in most kitchens. To validate the feasibility and safety of thi...

Burn-in faces significant challenges in recent CMOS technologies. The self-generated heat of each IC in a burn-in environment contributes to larger currents that can lead to further increase in junction temperatures, possible thermal run away, and yield-loss of good parts. Calculations show that the junction temperature is increasing by 1.45X/generation. This paper estimates the increase in jun...

Breadfruit (Artocarpus altilis) is a traditional staple crop grown for its starchy fruit throughout Oceania. This study therefore investigated the effect of maturity and different drying methods on some rheological and physicochemical properties of reconstituted breadfruit flour (Artocarpus altilis) (amala). Freshly harvested breadfruits (mature and immature) were washed in clean water to remov...
