I use the simulations of cosmological reionization to quantify the effect of the gas fraction suppression in the low density objects due to photoionization. I show that the Jeans mass does not match the characteristic mass scale below which the gas is efficiently expelled from the shallow potential wells, and which can be orders of magnitude lower that the Jeans mass. Instead, the filtering mas...

Silicosis is a fibrotic disease of the lungs caused by inhalation, retention, and pulmonary reaction to crystalline silica. Crystalline silica exposure is widespread, and silica sand is an inexpensive and versatile component of many manufacturing processes. Its use and the incidence of silicosis are increased in industrial operations by the mechanization and the use of sandblasting, drilling, p...

Our universe is magnetized and its constituents are the electrons, anti-electrons (positrons), ions and dust particles. Our objective here is to discuss the formation of large scale plasma structures based on a model associated with the Jeans instability in a self-gravitating multi-component fully ionized magnetoplasma. Assuming that the plasma particles are magnetized and charged dust grains f...

enim Jeans finishing is one of the most important value added activities in the washing plant to meet buyer requirements. It is done by creating numerous effects on it. Potassium Permanganate (PP) is a strong oxidizing agent used to make vintage look with acid stone wash. This present investigation deals with the simultaneous effect of processing time and concentration of PP on the physical and...

The belt loop is an important part of a standard five-pocket jeans, integrating functionality and aesthetics. Because common problems such as skewed loop, unequal lengths, improper slackness, double lines at the front pocket cover, exposed bottom asymmetry, too low or high position no light in back, we tracked sewing jeans production line, analyzed causes problems, came out with targeted soluti...
