Moving towards sustainable agriculture implies exploring the interconnections between farming and the environment, and soil is a key component of sustainability. Mulching is one of the methods to protect and enhance the productivity of the soil. We studied here the effect of mulching applied to mandarin tree rows for weed control in two localities near Tortosa, Spain, to compare its performance...

(2R,3R)-2,3-Diaminobutane-1,4-diol 6 and its dibenzyl ether 7 were efficiently synthesized starting from L-tartaric acid 1a. The crucial step, debenzylation of intermediate dibenzyloxydiazide 4, was accomplished in good yield by boron trichloride–dimethyl sulfide complex. The enantiomeric series was similarly obtained starting from D-tartaric acid. c 1997 Elsevier Science Ltd

Tartaric acid modified wheat bran was utilized as adsorbent to remove methyl blue, a basic dye from aqueous solution. Batch experiments were carried out to study the effect of various experimental parameters such as initial solution pH, contact time, initial dye concentration and adsorbent dosage, on dye adsorption. The results showed that the modification of wheat bran by tartaric acid signifi...

Adsorption behavior of chromium, Cr(VI) from wastewater has been investigated using clarified sludge (a steel plant waste material), rice husk ash and sawdust as non-conventional adsorbents. The studies were carried out at room temperature (30C) following batch adsorption technique in a reciprocating shaker. Factors affecting the adsorption characteristics such as agitation time, initial metal ...

Agricultural waste ashes are used as resource materials to synthesize new glass and glass-ceramics. The as-prepared materials are characterized using various techniques for their structural and dielectric properties to check their suitability in microelectronic applications. Sugarcane leaves ash exhibits higher content of alkali metal oxides than rice husk ash, which reduces the melting point o...

Soil stabilization is the alteration of property of locally available soil to improve its engineering performance. Stabilization can increase the shear strength of soil and control shrink – swell properties of soil, thus improving the load bearing capacity of a sub grade to support the pavements and foundation. The objective of this paper is to expose the possibilities of paper sludge and rice ...

The present paper deals with the development and validation of analytical method based on a single column high performance Ion chromatography with cation suppressed conductivity detection, developed for quantitation of tartaric acid. The diluent used for the preparation of sample solution was water and injected into a standard chromatographic system connected with 250mm length, 4.0 mm ID and 5....

The first stage in the preparation of rice for food is the threshing of the harvested crop to yield paddy rice. This consists of the rice berry (or grain) enclosed in a rough, fibrous and silicious husk. Further preparation consists of hulling to remove this husk, followed by milling which removes the outer bran layer of the berry. For some time before beriberi was shown to result from a defici...

In this work, after carbonization of two biomass wastes, rice husk and coconut husk, they were modified by hydrothermally synthesized cryptomelane manganese prepared into a solar interfacial evaporation system to explore their performance stabilization cadmium. The results demonstrate that the cryptomelane-modified biochar can obtain an rate 1.247 kg m−2 h−1 photothermal conversion efficiency 8...
