The ecological pollution by the harmful substances has become the significant worry globally. A wide scope of harmful pollutants are brought into the amphibian climate because of expanded industrialization, innovative turn of events, developing human populace and abuse of normal assets, agrarian and homegrown squanders run-off.
Nanochemistry is a branch of nanoscience that deals with the chemical applications of nanomaterials in nanotechnology. It involves the study of the synthesis and characterisation of materials of nanoscale size.
Coordination chemistry is the field which is concerned with the chemical interaction of organic and (or) inorganic ligand with transition and late transition group metal centres.
Brookhaven Lab scientists identified an enzyme (PHBMT1) that transfers p-hydoxybenzoate (green) to lignin building blocks in poplar. The resulting conjugate is then incorporated into the nascent lignin polymer, leading to p-hydoxybenzoate-decorated lignin. The discovery may enable scientists to engineer plants to accumulate more of this important industrial chemical building block. Credit: Brookhaven National Laboratory
The cost of manufacturing and distribution of apparel products are highly depended on the sewing thread consumption. Thus, the calculation of sewing thread consumption has to be done accurately using effective methods. Due to the inefficiency of the existing formulae, the predictions of thread requirement became inaccurate. The consumption calculations exhibit significant error percentages due to the ignorance of important parameters which effect on thread consumption. This study investigates on correlation of many parameters such as GSM, seam width, SPI, frequency, thickness of fabric and yarn count to thread consumption of over-lock stitch 514. The existing thread consumption formulae are optimized by considering new parameters, using regression analysis and geometrical modelling techniques. For the over-lock stitch 514, results indicate that above parameters significantly affect in determination of the thread consumption. This particular method addresses the following issues: In accurate consumption calculation, Excess seam length or inaccurate seam length, Use of predefined thread consumption factors and use to calculate thread consumption by only considering machine type. The error analysis of proposed formulae was performed to indicate that the proposed formulae more accurate compared to the current method of predicting sewing thread consumption. Therefore, the proposed formulae are expected to be a better approach to calculate thread consumption of over lock stitch 514.
