Coir pith, a by-product of industry, renewable sourceis dark brown in color, fibrous in condition. The physical properties and anatomical studies of various ages of coir pith were done to determine the efficiency of formation of primary and secondary cell wall in fresh and old coir pith.The cell wall structure, lignin composition and the anatomical view in the collected coir pith were examined ...

The location of the pith is an important feature of cross sections from tree logs. Images of log ends can be taken at little cost and at almost every stage in the log processing chain. Analysing images of rough log ends automatically requires robust pith estimation. This work evaluates two pith estimation algorithms using four different local Fourier Spectrum analysis methods. Proving that size...

Activated carbon (AC) has been prepared from raw coconut pith and coconut pith impregnated with H3PO4 and NaOH solutions separately. AC was characterized with SEM, particle size analyzer and proximate analyzer. Adsorption studies were carried out using UV and atomic absorption spectrophotometer to find its effectiveness. AC obtained from coconut pith treated with phosphoric acid was found compa...

Drying kinetics of coir pith was studied and the properties of compressed coir pith discs were analyzed. Coir pith particles were oven dried in the range of temperatures from 100 to 240 °C and the rehydration ability of compressed coir pith was evaluated by finding the volume expansion. The optimum drying temperature was found to be 140 °C. Hot air drying was carried out to examine the drying k...

PURPOSE We previously reported on a staging system and prognostic index (PITH) for portal vein tumor thrombosis (PVTT) in hepatocellular carcinoma (HCC) patients treated with radiotherapy (RT) at a single institution. The aim of this study is to validate the PITH staging system using data from patients at other institutions and to compare it with other published staging systems. MATERIALS AND...

Pith tissue from Nicotiana tabacum L. cv ;Maryland Mammoth' or ;Wisconsin 38' was isolated, free of vascular tissue, and cultured on a medium containing auxin but no cytokinin. Explants from the apical 1 cm of stem, within the pith rib meristem, initiated callus growth with 100% efficiency. Macroscopically visible callus was evident 5 days after the tissue was isolated, and the cultures grew pe...

Ethylene increases the pith peroxidase activity of intact tobacco plants (Nicotiana tabacum) but not of excised pith, either at atmospheric or reduced pressures. In the intact plant, the increased activity involves augmentation of the two constitutive anodic isoperoxidases. In the excised pith, ethylene strongly represses one injury-induced isoperoxidase, while not markedly affecting other isoz...

Coir pith is an organic matter which originates from the tropical hemisphere, especially from southeast Asia where coconut oil production is extensive. For professional oil winning companies, the husk of the nut is a waste product. These coconut husks mainly consist of coir pith and coir fibers. Initially, coir pith was considered a waste but now research has established widespread applications...

this study was conducted to compare fungi and whole rumen microorganisms (wrm) digestibility of treated sugarcane pith by fungi and of buffalos and holstein cows. dry matter (dm), neutral and acid detergent fiber (ndf and adf) digestibilities of steam treated sugarcane pith (stp) by fungi and wrm were compared with a two-steps digestion technique, gas production (gp) and specific rumen fungi cu...

WRKY proteins are one of the largest transcription factor families in higher plants and play diverse roles in various biological processes. Previous studies have shown that some WRKY members act as negative regulators of secondary cell wall formation in pith parenchyma cells. However, the regulatory mechanism of pith secondary wall formation in tree species remains largely unknown. In this stud...
