Pregled upotrebe plovućca i eko kamena u industriji pranja denima u slučaju održivosti

In denim washing industry pumice stone is a very popular material in enzyme or jumping process. Pumice stone is less costly and that's the only reason behind it's higher application. But pumice stone creates more sludge in ETP & requires more water in process which is not sustainable. Also for usage of pumice stone there is a higher possibility of damage issue in case of very light wash. In this study Eco Stone were used instead of Pumice stone to observe it's all kinds of outcome against Pumice stone with its sustainability. Because Eco stone require less water and create less sludge as its corrosion is lesser than Pumice stone. And for its smooth surface the possibility of physical damage of garments is lower.

Impact of Washing Process on the Physical Properties of Denim Fabric (Twill and Dobby)

The study was focused on investigating the impact of different washing processes (dark shade, medium shade, light shade) on various properties of denim fabric. Two different types of fabrics with twill and dobby weave constructions were produced from cotton, spandex, and polyester yarn, and different types of washing processes were applied. Dimensional stability, tensile strength, tearing strength, EPI and PPI, weight, colorfastness to rubbing, colorfastness to perspiration (acid and alkaline), and colorfastness to water was investigated and comparisons were made statistically between the before washed sample and after washed sample. It is found that the process result shows better tear and tensile strength in case of dark & medium shade wash than light shade wash. On the other hand, weight and EPI & PPI have shown better result for light wash than other wash. Colorfastness to rubbing, Colorfastness to water, and Colorfastness to perspiration (acid and alkaline medium) are similar. The shrinkage% is higher especially in the weft direction of the fabric for light wash than the dark wash.

Radionuclide content of selected root vegetables as influenced by culinary preparation

A greenhouse study involving root vegetables (carrot, red beet, and turnips) was conducted primarily to evaluate the effect of culinary processing (light washing, scrubbing, and peeling) on the radionuclide content of the edible portions. In terms of concentration ratio of the radionuclides left in roots after peeling, the trend follows: 90 Sr> 137 Cs⪢ 234 U≅ 238 U⩾ 238 Pu . The actinide contents in the roots were apparently due to surface adherence of the contaminated soil particulates as indicated by the diminution of the contents upon brushing the surface, which were further decreased by peeling the skin. Rigorous culinary processing of roots, such as scrubbing or peeling, could substantially diminish the contents of the actinides, but not of the more mobile 90 Sr and 137 Cs .

A chariot larnax from Mycenae

The two unusual fragments illustrated in Plate 14 and Fig. I were found at Mycenae in 1950, but were not identified until 1957, when the pottery from the Cyclopean Terrace Building Area was being restudied for the publication which appears in this volume. They come from the East Trench which ran east-west immediately east of the east wall of the Cyclopean Terrace Building proper and which disclosed the drain marked in the plan. They were found at a depth of more than 2·40 m., i.e. below the level of the drain. It seems likely that the fill of this area dates mainly from the period of the building of the Cyclopean Terrace Building (when the drain also must have been built) in the early part of L.H. IIIB, but the pottery in all layers of this trench was contaminated by stray sherds of later Mycenaean, Geometric, and Hellenistic wares. Therefore, though a date in the period preceding early L.H. IIIB is very likely, it cannot be assured.The pieces, which are 0·02 m. thick, are made of a heavy buff clay with considerable grit and chaff covered with a light wash through which the grit shows, giving the appearance known as ‘oatmeal’. The paint is a semi-lustrous red-brown. This fabric is similar to, though heavier than, that of the stirrup jars from the nearby House of the Wine Merchant. It is clear from the scene on the outside that the two fragments are not adjoining, but come from the opposite sides of the same vessel. The shape, fabric, and schemes of decoration seem to indicate that these are fragments of a bath larnax (FS 1).
