Disposal and storage of raw poultry manure has become an environmental problem because of the associated air, water and soil pollution. Poultry manure begins to decompose immediately after excretion giving off ammonia which, in high concentrations, can have adverse effects on the health and productivity of birds as well as the health of the farm workers. Application to land is the most common w...

ABSTRACT-The influence of intensive crop rotation on the distribution of potassium forms and clay mineralogy was assessed under a Mediterranean condition in the Piranshar region, northwest of Iran. For this purpose, surface soil samples in relation to six soil sub-groups from crop rotationfiled (sugar beet, wheat, pea, and barley) over five decades and the adjacent uncultivated lands were descr...

Abstract Several countries have implemented the use of biodiesel as a diesel fuel blend. Indonesia currently implements highest percentage biodiesel, reaching 30% (B30), starting from 2020. Strict quality standards been worldwide, such ASTM D6751 (USA), EN 14214 (EU), JASO M360 (Japan), and SNI 7182:2015 (Indonesia). Prior to blending with diesel, must comply specification. One most concerning ...

We studied dynamic processes in drying drops of model protein-salt solutions, using an uncoated quartz resonator as a biosensor. To measure these processes we developed a method based on recording the dynamics of the Acoustic-Mechanical Impedance (AMI) of a drop as it dried on the surface of a quartz resonator oscillating at a resonant frequency of 60 kHz. The aim of this work was to highlight ...

Fuel blending is a widely used approach in biomass combustion, particularly for feedstocks with low calorific value and high moisture content. In on-site sanitation technologies, fuel blending is proposed as a pre-treatment requirement to reduce moisture levels and improve the physiochemical properties of raw faeces prior to drying. This study investigates the co-combustion performance of wood ...

The effect of pretreatment methods (soaking in water, potassium metabisulphite solution, and blanching) and drying methods (sun and oven) on some quality attributes of flour from ten varieties of sweet potato roots were investigated. The quality attributes determined were chemical composition and functional properties. Data obtained were subjected to descriptive statistics, multivariate analysi...

Potassium titanate, K2TiO3, with a chain structure of TiO5 polyhedra was exfoliated in an aqueous nitric acid solution of pH ≤ 1 and Tyndall scattering due to the colloid formed by the exfoliation was observed. The colloidal particle size measured by dynamic light scattering was approximately 300 nm. The stripe pattern observed by transmission electron microscopy for the aggregated grains after...

We were able to produce the first ever meltderived bioactive glass scaffold that met the requirement of an ideal bone scaffold by using the gel-cast foaming process and a new glass composition. However, initially a small fraction of sodium potassium sulfate crystals formed during processing. The purpose of this work was to study and prohibit the growth of those crystals, which was the result of...

Both fetal and adult human corneas were subjected to a variety of histochemical techniques for the demonstration of catecholamines. The techniques included both sodium-potassium-glyoxylic acid-induced fluorescence (SPG) and formaldehyde-induced fluorescence after freeze-drying (FIF) procedure. In fetal corneas the presence of adrenergic nerve fibers could be demonstrated by both SPG and FIF tec...
