Abstract:
A right module <em>M</em> over an associative ring <em>R</em> with unity is a <em>QTAG</em>-module if every finitely generated&nbsp;submodule of any homomorphic image of <em>M</em> is a direct sum of uniserial modules. Motivated by the <em>h</em>-purity and <em>h</em>-purifiability, we study strongly <em>h-</em>purifiability in <em>QTAG</em>-modules and obtain several characterizations. Also, some new&nbsp;invariants of <em>QTAG</em>-modules are highlighted with the help of h-purifiable submodules and <em>h</em>-pure hulls. It is found&nbsp;that a strongly <em>h</em>-purifiability to be an int

Abstract:
AbstractThe aim of this study was to determine the in vitro digestibility and in sacco disappearance of dry matter (DM) and neutral detergent fibre (NDF) in total almond hulls (TAH), pure almond hulls (PAH) or Debris. The TAH were used because there are no data on the effect of debris (non-hull material) on the nutritional value of almond hulls. Twelve samples of commercial almond hulls were used, with one subsample representing the TAH and the other subsample hand sorted to separate the hulls (PAH) from Debris. Gas production and Ankom Daisy method were used to determine in vitro digestibilit

Abstract:
The article presents the results of experimental studies of an arable unit consisting of a 409KW Challenger-865V tractor and a towed combined plough-ripper COMBI-7. The ripper plough consists of a frame on which four rows of working bodies are placed frontally to the direction of movement, the first two with ripping housings, the last two with chisel housings. The trailed gun is equipped with an arable land surface leveler. The gripping width of the ripper plough is 7 m. Field studies of the operation of the Challenger-865B+COMBI-7 unit were carried out in arid conditions of the Left-bank zone

Abstract:
<strong>Introduction:</strong> Agriculture fields such as wood, bast fibers, gasses, along with aquatic animals, algae, fungi, etc. are a major source of component nanocellulose and also a major source of industrial waste which is utilized as adsorbents (1). Rice straw act as a good adsorbent for heavy metal removal due to the presence of binding sites cellulose, hemicellulose, and lignin (2). Chemically modified nano-cellulose is processed with 5% NaOH, sodium chlorite for bleaching purposes which is further followed by hydrolyzing the material along with ultrasonication (3).

Abstract. HUmic-LIke Substances (HULIS) have been identified as major contributors to the organic carbon in atmospheric aerosol. The term HULIS is used to describe the organic material found in aerosol particles which resembles the humic organic material in river and sea water and in soils. In this study two sets of filter samples from atmospheric aerosols were collected at different sites. One sample was collected at the K-puszta rural site in Hungary, about 80 km SE of Budapest, and a second set of samples was collected at a site in Rondônia, Amazonia, Brazil, during the LBA-SMOCC biomass bu

<strong>ABSTRACT</strong> Free radicals or highly reactive oxygen species are capable of inducing oxidative damage to human body. Antioxidants are the compounds which terminate the attack of reactive species and reduce the risk of diseases. <em>Hemidesmus indicus</em> is used in treatment of various disorders in humans. The study was conducted to determine the antioxidant properties of<em> Hemidesmus indicus</em> leaf and root extracts in methanol. The antioxidant activity of this medicinal plant was evaluated by measuring reducing ability, free radical scavenging activity by DPPH and ABTS.&nb

Abstract:
The corrosion of steel structures in aggressive marine environments is a vital issue that induces significant degradation of their performance and lifespan. Herein, three arc-sprayed ZnAl coatings with varied Al contents of 0 wt.%, 15 wt.%, and 50 wt.% were deposited onto a hull steel substrate. The effect of Al content on the long-term corrosion protection performance of ZnAl coatings left in a chloride-containing solution for 840 h was systematically investigated.

Abstract:
Fouling is an adverse problem for ship. Fouling itself is some kind of marine biota like shells, mussels, or barnacles, which grow and live on the surface of ship’s hull or inside the ship’s piping system. Many methods have been applied to prevent fouling. Impressed Current Anti Fouling (ICAF) was developed and applied as an alternative in mitigation of fouling. The aim of the research was to determine the effects of electrical current, duration time, salinity on Anadara granosa death in simple ICAF system. The simple ICAF reactor was operated in electric current of 1.5 A, and duration time (1

We evaluated two unmanned aerial systems (UASs), namely the DJI Phantom 4 Pro and DJI Mavic Pro, for 3D forest structure mapping of the forest stand interior with the use of close-range photogrammetry techniques. Assisted flights were performed within two research plots established in mature pure Norway spruce (Picea abies (L.) H. Karst.) and European beech (Fagus sylvatica L.) forest stands. Geotagged images were used to produce georeferenced 3D point clouds representing tree stem surfaces. With a flight height of 8 m above the ground, the stems were precisely modeled up to a height of 10 m,
