Lignin is a complex biopolymer which forms the hard part of woody tissues. It’s high molecular weight and rigid nature makes it recalcitrant for digestion. Lignin is exudated to access other compounds like cellulose, hemicellulose etc., for industrial production of bioethanol, paper etc., Paper pulp industries being one of the major wood processers remove lignin through various thermochemical methods like sulphonation, chlorination etc., to give a soft texture for paper.

The regeneration of roots and shoots through leaf cuttings is a feasible technique for plant clonal propagation, using a quite available organ, which can be collected without great damage to the plant. A protocol of propagation through leaf cuttings was defined to Piper hispidum, a plant whose compounds have great potential use in medicine and agriculture. Leaves of three sizes were used, according to their length: small (4-6 cm), medium (7-9 cm) and large (10-12 cm). The leaves were cut in halves (apical and petiolar) by transverse cutting in the middle of the leaf blade.

This paper addresses the application of robots to aid in the physical rehabilitation of patients. The objective is to present the design of a pneumatically driven robotic workbench with force control for rehabilitation of upper and lower limbs. Recently, the research in the mechatronic systems field is being developed to assist the physical rehabilitation of people who have suffered some form of serious physical injury.

In the last 10 years, the Cassava Brown Streak Disease has spread across Africa from the east coast of Africa to central Africa. Similar root necrosis to cassava brown streak disease have also been identified in the Democratic Republic of Congo where the first symptoms were identified in 2002 in Kinshasa and Central Kongo province. In 2012, the presence of cassava brown streak disease was confirmed in eastern Democratic Republic of Congo. All attempts since 2002 in western Democratic Republic of Congo to identify the cause of these root necrosis failed.

We propose, with the writing of this text, the accomplishment of a survey of data in the bibliographical field, that makes possible to construct a dialogue between the thematic technical formation of young people of the field and their relation with the human ecology. Therefore, the main objective of this work is to carry out a systematic review, which we call bibliographic mapping, as a way to broaden the debate and strengthen the discussion about the technical formation of young people in the construction of a dialogue with Human Ecology.

A field experiment was conducted at research and demonstration block of Research Institute on Organic Farming, UAS, GKVK, Bengaluru during 2016 and 2017 to study the effect of different proportions of organic manures viz., compost, vermicompost and poultry manure on growth and yield of okra. The experiment was laid out in Randomised Completely Block Design. There were twelve treatments consisted with different proportions of organic manures and these were replicated thrice.

The study was conducted to identify some different helminth parasites infecting Rock pigeons in Qena province. The gastro-intestinal tracts of 32 specimens of pigeon (Columba livia) were dissected parasitologically for detect helminthes infection. Of these, 11 (34.3%) were infected by 3 species of helminths, comprising 2 species of cestodes and one species of common nematodes Ascaridia columbae 8 (25%), The infection with cestode species was 5(15%) in the two families Dilepididae Dilepis undula Schrank,1788; and Anoplocephalidae Atriotaenia minuta n. spp.

Introduction: Field experiments were conducted for two years in sandy clay loam soil to study the effect of organic sources and mineral nitrogen on growth parameters, yield attributes and yield of rice. The treatments consisted of addition of different organics viz., composted coir pith (CCP), green manures (GM), sugarcane trash compost (STC), vermicompost (VC), poultry manure (PM) and FYM applied at 100% RDN and combination of above organics @50% N and urea@50%N besides 100% RDN as urea and control.

This study was designed to examine the possible effects of instructional strategies on mathematical discourse. The effectiveness, retention, application and the usefulness of teacher-centered instruction were in question. To obtain data, questionnaire, classroom observation, and semi-structured interviews were used. A total of one hundred fifty-six teachers and five hundred sixteen students from the entire sample schools were selected using simple random sampling technique for the questionnaire and classroom observation. Twenty teachers and thirty-five students were interviewed.

Objective: To analyze the perception of patients with Chronic Renal Disease related to hemodialytic treatment. Method: This is a qualitative, descriptive and exploratory study developed with nine patients on hemodialysis treatment followed in a renal clinic. The data collection took place in March and April of 2017 through a characterization questionnaire and focused interview. The data were submitted to thematic analysis. Results: There were three categories: the sodium and Chronic Renal Disease; Diabetes Mellitus in chronic renal patients and patient acceptance of hemodialysis.
