Utilization of organic-residues as potting media: Physico-chemical characteristics and their influence on vegetable production.

Soilless agriculture is acknowledged worldwide because it uses organic leftovers as a means of supporting intensive and efficient plant production. However, the quality of potting media deteriorates because of lower nutrient content and excessive shrinkage of most organic materials. A current study was undertaken to identify the optimal blend of locally available organic materials with desirable qualities for use as potting media.

Cyclic and linear trajectories of ecosystem evolution on sand dunes in Siberian taiga: A comprehensive analysis.

Extensive unforested sandy areas on the margins of floodplains and riverbeds, formed by dunes, barchans, and accumulation berms, are a ubiquitous feature across northern Eurasia and Alaska. These dynamic landscapes, which bear witness to the complex Holocene and modern climatic fluctuations, provide a unique opportunity to study ecosystem evolution. Within this heterogeneous assemblage, active dunes, characterized by their very sparse plant communities, contrast sharply with the surrounding taiga (boreal) forests common for the stabilized dunes.

Polycyclic Aromatic Hydrocarbons (PAHs) and Metals in Diverse Biochar Products: Effect of Feedstock Type and Pyrolysis Temperature.

Biochar's agricultural and environmental benefits have been widely demonstrated; however, it may cause environmental contamination if it contains large amounts of pollutants such as polycyclic aromatic hydrocarbons (PAHs) and heavy metals (HMs). Therefore, this study aimed to assess the contents of PAHs and HM in a range of biochars generated from different sources and pyrolysis temperatures. A range of feedstock was converted to biochar, including sewage sludge (SS), olive mill pomace (OP), feather meal (FM), soft offal meal (CSM), chicken manure (CM), and date palm residues (DPR).

Concomitant Mitral Valve Repair vs Replacement During Surgical Ventricular Restoration for Ischemic Cardiomyopathy.

There is no consensus regarding mitral valve management during surgical ventricular restoration (SVR) for ischemic cardiomyopathy. We compared the impact of SVR with mitral valve repair (MVr) vs replacement (MVR) on postoperative outcomes and long-term survival in ischemic cardiomyopathy and mitral regurgitation patients. This study included 112 patients who underwent SVR from 2009 to 2018 with MVr (n = 75) or MVR (n = 37).

Extracorporeal membrane oxygenation for postcardiotomy cardiogenic shock after valve replacement.

Background: Limited data evaluated the outcomes of extracorporeal membrane oxygenation (ECMO) in patients with prosthetic valves. This study aimed to compare the outcomes of ECMO support for postcardiotomy cardiogenic shock in patients with mechanical versus bioprosthetic valves.

Methods: This retrospective study included patients with ECMO support for postcardiotomy cardiogenic shock after valve replacement.

Mesoporous Activated Carbon from Leaf Sheath Date Palm Fibers by Microwave-Assisted Phosphoric Acid Activation for Efficient Dye Adsorption.

Remazol Brilliant Blue R (RBBR) is a common dye used in the industry, and its presence in wastewater and discharge into the environment can create a serious concern for the ecosystem and human health. Activated carbon produced from crop residues has emerged as a promising technique for removing contaminants from wastewater. In this study, leaf sheath date palm fiber-based activated carbon (LSDAC) was synthesized via phosphoric acid, HPO, treatment, followed by a microwave-induced carbonization process.

Myocardial recovery in a patient with dilated cardiomyopathy after short-term biventricular assist device support.

Management of patients with end-stage heart failure is still challenging. We report a case of idiopathic dilated cardiomyopathy who went through a challenging course. The case was presented as acute heart failure syndrome, which rapidly declined into cardiogenic shock and cardiac arrest that required an extracorporeal membrane oxygenator, then biventricular assist device implantation for circulatory support.

Physio-chemical characterization of indigenous agricultural waste materials for the development of potting media.

Organic residues are an important factor that directly affects fruiting tree seedlings' health at earlier stages. It provides a suitable environment for seedling growth by providing better nutrient ions, water, and aeration. However, low organic contents and high shrinkage of most organic materials mostly deteriorate ideal potting media characteristics.
