Sampah daun pohon ketapang merupakan sampah organik, karakter adalah meranggas atau menggugurkan daunnya secara massal dua kali dalam setahun bertujuan untuk mengurangi penguapan, sehingga dimungkinkan terjadinya penumpukkan jumlah yang banyak. Limbah plastik polypropylene (PP) tidak mudah terurai (non-biodegradable) waktu singkat dapat mencemari lingkungan. Penelitian ini dilakukan sebagai alt...

Heterotrophic activity was measured through a vertical profile in Halifax Harbor sediments using 14C labeled glucose, glutamate, and lactate as substrates. A modified heterotrophic potential method was used to detect the amount of label that was converted to low molecular weight metabolites as well as the amounts respired to CO, and incorporated into cellular material. For all three substrates,...

Two field experiments were conducted for two years with the aim of studying the effects of deep tillage and straw returning on soil microorganism and enzyme activity in clay and loam soil. Three treatments, (1) conventional tillage (CT), shallow tillage and straw returning; (2) deep tillage (DT), deep tillage and straw returning; and (3) deep tillage with no straw returning (DNT), were carried ...

Microalbuminuria is a marker of generalized endothelial dysfunction resulting from arterial stiffness or insulin resistance, and brachial-ankle pulse wave velocity (baPWV) is a good measure of arterial stiffness. We aimed to investigate whether elevated baPWV is independently associated with microalbuminuria. This study included 1,648 individuals aged over 40 who participated in the baseline Mu...

A field experiment was conducted during Kharif season-2019 at Agricultural Research Station, Chintamani, Karnataka. The consisted of four levels spacing (45 × 15, 45 30, 60 and 30 cm) three fertilizer (40:20:20, 60:40:40 80:60:60 kg NPK ha-1). arranged in a statistical design Factorial Randomized Complete Block Design (FRCBD) with replications to determine the influence different on growth, yie...

The soils affected by the spill of a pyrite mine were analysed in 100 sampling points at three depths (0-10, 10-30, and 30-50 cm) in 1998 (after the tailings were removed), 1999 (after the cleaning of the highly contaminated areas), and 2004 (after the tilling of the upper 20-25 cm). The comparative study reveals that the removal of the tailings left a heterogeneous distribution pattern of the ...

Forty percentage of UK peatlands have been drained for agricultural use, which has caused serious peat wastage and associated greenhouse gas emissions (carbon dioxide (CO2) methane (CH4)). In this study, we evaluated potential trade-offs between water-table management practices minimizing emissions, while seeking to sustain romaine lettuce production: one the most economically relevant crop in ...

PURPOSE The purposes of this study were to demonstrate the feasibility and accuracy of single-source dual-energy (DE) computed tomography (CT) with sequential data acquisition and a coregistration motion correction algorithm for urinary stone characterization and to evaluate the value of iterative reconstructions (IRs) in DE imaging. MATERIALS AND METHODS Thirty-five urinary stones were place...

BACKGROUND In patients with acute lung injury (ALI)/acute respiratory distress syndrome (ARDS), the use of alveolar-recruitment maneuvers to improve oxygenation is controversial. There is lack of standardization and lack of clinical studies to compare various recruitment maneuvers. Recruitment maneuvers are closely linked to the selection of positive end-expiratory pressure (PEEP), which is als...
