Influence of Low-Temperature Plasma Treatment on The Liquid Filtration Efficiency of Melt-Blown PP Nonwovens in The Conditions of Simulated Use of Respiratory Protective Equipment

Filtering nonwovens produced with melt-blown technology are one of the most basic materials used in the construction of respiratory protective equipment (RPE) against harmful aerosols, including bioand nanoaerosols. The improvement of their filtering properties can be achieved by the development of quasi-permanent electric charge on the fibres. Usually corona discharge method is utilized for this purpose. In the presented study, it was assumed that the low-temperature plasma treatment could be applied as an alternative method for the manufacturing of conventional electret nonwovens for the RPE construction.
Materials genomics‐guided ab initio screening of MOFs with open copper sites for acetylene storage

Discovering high-performance metal-organic frameworks (MOFs) with open metal sites has become an increasingly hot research topic in the field of safe storage and transportation of acetylene. Following the concept of Materials Genomics proposed recently, a database of 502 experimental MOFs was built by searching the structures deposited in the CSD with the dicopper paddle-wheel node Cu2(COO)4 as the characteristic materials gene. On the basis of the developed ab initio force field, a high-throughput computational screening was conducted to examine the property-performance relationships of MOFs containing Cu-OMS for C2H2 storage at ambient conditions. The optimal ranges of the structural and energetic features for the design of such MOFs were suggested. From our computational screening, three potentially promising MOFs were identified which exhibit a performance outperforming those MOFs reported experimentally so far with record high gravimetric C2H2 uptakes, both in the total and deliverable adsorption capacities.

Reducing VOC off-gassing during the production of pelletized steam-exploded bark : impact of storage time and controlled ventilation

Volatile organic compound (VOC) off-gassing behavior of thermally treated biomass intended for bioenergy production has recently been shown to be vastly different from that of untreated biomass. Simple measures to reduce emissions, such as controlled ventilation and prolonged storage time, have been suggested but not yet studied in detail. In the present study, we monitored how VOC off-gassing was reduced over time (24–144 h) in enclosed storage with and without ventilation. Steam-exploded bark was collected directly from a pilot-scale steam explosion plant as well as before and after subsequent pelletizing. Active Tenax-TA absorbent sampling of VOCs was performed from the headspaces of a bench-scale sample storage setup. The impact of storage time and ventilation on VOC levels was evaluated through multivariate statistical analysis. The results showed that relative VOC concentrations in the headspace were reduced by increased storage time, with heavier VOCs reduced at a higher rate. VOC composition was n.

Rumen Methanogens Diversity Analysisin Indian Buffaloes Using PCR-DenaturingGradient Gel Electrophoresis

Buffaloes with a global population of 206.6 millions remain an important ruminant species throughout the world [1]. India harbours 109.85 million buffaloes [2], which is about 53% of the global buffaloes population. Although, buffaloes are one of the important sources of animal origin food in the country, nevertheless enteric methane emission from them always remains an important concern. In addition to the contribution in global warming, enteric methane from the ruminants also epitomizes a significant loss of feed energy [3]. The annual enteric methane emission from the global buffaloes is about 11.05 Tg (teragram), whereas Indian buffaloes contribute 2.91 Tg [4]. Methanogens are unicellular organism belong to the domain Archaea and phylum Euryarchaeota [5]. Methane is a metabolic by-product produced by methanogens in strictly anaerobic conditions. Till date, 155 methanogens species belonging to 29 genera, 14 families and 6 orders have been isolated from the different ecosystems [6]. Methanogens are present in the rumen between an abundance of 107-1010 per gram of rumen content [7]. The substrate requirement of rumen methanogens is diverse, and majority of the archaea utilize carbon dioxide and hydrogen, while some of them prefers methanol, and methylamines [8] or formate [9] as substrate. Isolation of the archaea from rumen always remains a tedious task and that is why only limited (~10) species have been isolated till now [10,11]. Due to the culturing difficulties, it is likely that major fraction of the rumen methanogens is still to be identified [12,13]. Understanding of the rumen archaea is of utmost importance to develop the effective enteric methane mitigation strategies.

Assessment of Helicobacter pylori Infection as a Risk Factor for Coronary Artery Disease in Gaza Strip

Background: Coronary artery disease (CAD) is a common form of cardiovascular disease (CVD). It caused by atherosclerosis, which restricts blood flow to the heart, and when the blood flow completely cut off, the result is heart attack. Cardiovascular disease remains the leading cause of death in the world as well as in Palestine. Helicobacter pylori (H. pylori) infection believed to be associated with CAD. Objective: Assessment of H. pylori infection as a risk factor for CAD in Gaza strip. Material and methods: This case-control study comprised 62 CAD patients (Cases: 31 males and 31 females) and 62 healthy controls (31 males and 31 females). Questionnaire interview was applied. Blood samples were collected, processed and analyzed. Serum H. pylori IgG, cholesterol, triglycerides, low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), creatinine phosphokinase (CK) and creatinine phosphokinase MB (CKMB) were determined. White blood cell (WBC), red blood cell (RBC), hemoglobin (Hb) and platelet (PLT) were also determined. Data were analyzed using SPSS version 18.0. Results: Coronary artery disease was more prevalent among less educated and unemployed individuals, families with low income, individuals with family history of the disease as well as among smokers. The number of cases who had diabetes mellitus, hypertension and peptic ulcer was significantly higher than that of controls. The BMI was significantly higher in cases compared to controls (31.7±4.8 vs 27.6±4.4, % difference=13.8 and P=0.000). There were significant elevations in the activities of serum AST and LDH in cases compared to controls (36.3±24.5 and 540.8±310.7 U/L vs 18.6±6.0 and
Development and Quality Evaluation of Ready to Serve (RTS) Beverage from Cape Gooseberry (Physalis peruviana L.)

This study aimed to develop a process for the development of ready to serve (RTS) beverages from enzyme liquefied (pectinase) Cape gooseberry juice with additives and preservatives. Storage stability of the RTS beverage at both refrigerated temperature (LT: 4 ± 1 °C) and room temperature (RT: 27 ± 2 °C) were evaluated for 90 days for microbial, sensorial and physicochemical quality parameters. The stability of RTS beverage stored at LT (4 ± 1 °C) was excellent with a retention of the primary quality attributes ascorbic acid (15.44 mg/100 mL), total phenolic content (15.50 mg GAE/100 mL), total carotene (1.07 mg/100 mL), β-carotene (0.78 mg/100 mL), high viscosity (30.29 cp), and with high sensory scores of the product (8.3) up to 90 days as compared to the overall acceptability (6.5) of RT stored RTS for 60 days. Additionally, both the LT and RT stored RTS beverages had microbial counts within the permissible limits. Therefore, both beverages were safe to consume at the end of storage duration. In conclusion, the RTS beverage developed from Cape gooseberry could be served as functional health drink alternative to synthetic soft drinks due to its unique features (high nutritive values, high organoleptic values and high stability) of the product.
Egress and invasion machinery of malaria: an in-depth look into the structural and functional features of the flap dynamics of plasmepsin IX and X

Plasmepsins, a family of aspartic proteases expressed by Plasmodium falciparum parasite, have been identified as key mediators in the onset of lethal malaria. Precedence has been placed on this family of enzymes due their essential role in the virulence of the parasite, thus highlighting their importance as novel drug targets. A previously published study by our group proposed a set of parameters used to define the flap motion of aspartic proteases. These parameters were used in the study of Plm I–V and focused on the flap flexibility as well as structural dynamics. Recent studies have highlighted the essential role played by Plm IX and X in egress and invasion of the malarial parasite. This study aims to close the gap on the latter family, investigating the flap dynamics of Plms IX and X. Molecular dynamics simulations demonstrated an “open and close” mechanism at the region of the catalytic site. Further computation of the dihedral angles at the catalytic region revealed tractability at both the flap tip and flexible loop. This structural versatility enhances the interaction of variant ligand sizes, in comparison to other Plm family members. The results obtained from this study signify the essential role of structural flap dynamics and its resultant effect on the binding landscapes of Plm IX and X. We believe that this unique structural mechanism may be integrated in the design and development of effective anti-malarial drugs.
Carbon dioxide capture under postcombustion conditions using amine-functionalized SBA-15: Kinetics and multicyclic performance

ABSTRACT In this work, ordered mesoporous SBA-15 was synthesized and functionalized by polyethyleneimine (PEI). The morphological properties were characterized by N2 adsorption/desorption, field–emission scanning electron microscopy (FE-SEM), high–resolution transmission electron microscopy (HR-TEM) and Fourier transform infrared (FTIR) spectroscopy methods. The carbon dioxide (CO2) uptake on the sorbents, kinetics of CO2 adsorption/desorption and long-term multicycle stability of PEI-impregnated sorbent were measured. An optimal amine loading of 50 wt. % showed a CO2 adsorption capacity ~3.09 mmol g−1 using 10% pre-humidified CO2 at 75°C. The presence of moisture in flue gas showed a promoting effect in CO2 sorption capacity. The temperature swing adsorption/desorption cycles showed excellent multicycle stability over 60 cycles during 65 h of operations under humid CO2.
Magnetically Induced Low Adhesive Direction of Nano/Micropillar Arrays for Microdroplet Transport

A kind of superhydrophobic magnetic nano/micropillar array (MNA) with optimized intrinsic dynamic wetting property has characteristics of magnetically induced dynamic tilt‐angle changes, which achieves the controlling of the directional droplet transport effectively. It is revealed that MNA has a low adhesive gradient along the direction of magnetically induced tilt‐angles. A tilt‐angles of nano/micropillars in the range of 0°–59° is realized by controlling the magnetic field intensity (0–490 mT), so that a droplet (10 µL) can be transported on MNA from one pillar to the next along the tilt‐angle direction. It is proposed that the continuous changes of magnetically induced dynamic tilt‐angles on MNA induce a gradient driving force to act on the droplet, in addition to cooperation with the low adhesive direction that results from unidirectional gradient discontinuous solid–liquid–gas three phase contact lines. The finding offers insight into designing of surface materials that can be extended into microfluidics for controlling of droplet motion and others.
Influence of selenium on carbohydrate accumulation in developing wheat grains

ABSTRACT The present investigation reports the effects of different doses of sodium selenate and sodium selenite on its uptake, carbohydrate composition, and sucrose and starch metabolizing enzymes in flag leaf and developing grains of wheat grown under greenhouse conditions. Selenium (Se) concentration increased significantly in leaves and developing grains of Se-treated plants compared to control at different intervals post-anthesis. Total soluble sugars and sucrose concentrations in developing grains increased due to various Se treatments. Different selenite treatments increased sucrose synthase activity from 10 to 20 days post-anthesis and increased starch accumulation compared to control plants. Lower starch accumulation in selenate than control and selenite treatments was observed. The activities of α, β and total amylase, invertase and sucrose synthase increased whereas sucrose phosphate synthase declined. Results indicated that Se accumulation causes disturbances in carbohydrate metabolism that is dependent on Se concentration, form and the development stage of the plant.

There is a lack of literature studies examining the relationship between Lessig’s four modalities and the challenges of big data analytics adoption. This study assesses the implementation of Lessig’s Four Modalities for the adoption of big data analytics in Malaysia SMEs based on literature review findings. To identify the challenges of applying big data analytics in Malaysian SMEs, a comprehensive literature search was conducted using databases, journals, Google Scholar, and IEEE publications. This research provides practical insights into the challenges of dealing with big data in SMEs. It is envisioned that Lessig’s four modalities proposed in this study, namely legal, architecture, social, and market factors, can be applied by Malaysian SMEs to adopt big data analytics.
Rational Synthesis of Fullerenes

Fullerenes are a unique family of carbon-based cage molecules, which attract interest because of their remarkable properties and potential applications. Most effort so far has been focused on the study of C60 and C70, whereas other members of the huge fullerene family remain poorly explored. One of the main challenges in this field is the developing of the synthetic methods, which are suitable for the production of these unique materials in isomer-pure form in macroscopic amounts. Here, we review studies toward the rational synthesis of fullerenes from molecular precursors that have been published to date. The scope and limitation of the zipping strategy are discussed. The relevance and prospects for construction of the fullerene cages and related carbon-based nanostructures via cyclodehydrofluorination (C─F bond activation) are highlighted.
Effect of Some Chloride Salts on Swelling Properties of Expansive Soil

Chemical stabilization has been increasingly adopted for improving the properties of expansive soils in recent years. The use of chloride salts to stabilize expansive clays has been investigated by many researchers. In this regard an attempt has been made to evaluate the influence of adding three chloride salts (AlCl 3 , FeCl 2 , NH 4 Cl) to an expansive clay of high swelling potential on its swelling properties. Laboratory tests conducted on natural and treated soils include Atterberg's limits, free swell, swell potential, and swell pressure tests. Various amounts of each salt (0%, 5%, 10%, and 15%) were added to the soil to study their effect on plasticity and swelling characteristics. Comparing the results obtained for the natural and treated soils, the increase in the percentage of the salt decreased the liquid limit and plasticity index of the soil. The reduction in the plasticity index values of the treated soil with addition of 15% salt is more than 78% of the virgin soil. A significant decrease in the free swell index, swell potential and swell pressure of the treated soil was experienced. The tests results indicated that among the three chloride salts tested, ammonium chloride showed promising results. It can be concluded that the chloride salts studied had shown great potential to improve swelling properties of expansive soils.
Global collisional-radiative model for optical emission spectroscopy of argon and argon-containing plasmas

Stos-Strahlungsmodelle (SSM) werden in der Niedertemperatur-Plasmaphysik verwendet, um die Eigenschaften der Elektronen des Plasmas aus optischen Emissionsspektren zu bestimmen. In dieser Dissertation wurde ein SSM fur Argon-Plasmen entwickelt und evaluiert. Verschiedene Prozesse wie Elektronenstos-Anregung und Elektronenenergieverteilung, Strahlungsreabsorption und Diffusion von metastabilen Atomen wurden im Detail untersucht. Parameter und Inputdaten wie Elektronenstos-Wirkungsquerschnitte und Einsteinkoeffizienten werden diskutiert und ihr Einfluss auf die Ergebnisse der Modellierung wird explizit gezeigt. Um die Ergebnisse des SSM zu evaluieren, werden experimentelle Daten verschiedener Entladungen bei unterschiedlichen Bedingungen herangezogen. Das Argon-SSM wird zudem zur Analyse reaktiver Plasmen eingesetzt, indem Argon in kleinen Mengen beigemischt wird. Bei hoherem Druck verandert sich das SSM deutlich, wie anhand eines Wasserstoff-Silan-Argon-Plasmas gezeigt wird.
Protecting Growth - A Quantile Vector Autoregression to Evaluate the Power of Monetary Policy in Mitigating the Transmission of Financial Stress on GDP Growth

This paper investigates the eﬀectiveness of monetary policy in reducing Growth at Risk during ﬁnancial stress scenarios. For this analysis a quantile vector autoregressive (QVAR) model is used due to its nonlinear properties. Using quantile regressions in a VAR setting allows to explore the dynamics between economic growth, monetary policy and ﬁnancial stress in all parts of the distribution of the variables. The analysis shows that a loosening in monetary policy eﬀectively reduces the risk to GDP growth caused by shocks in ﬁnancial stress. Moreover, monetary policy seems to be more eﬃcient in times of tight ﬁnancial conditions. The results suggest nonlinear interactions along several dimensions between GDP growth, ﬁnancial stress and the change in monetary policy. These ﬁndings indicate that not only linear VARs, but also frequently used threshold VARs might miss important features of the data. Including monetary policy uncertainty (MPU) leads to insigniﬁcantly better distribution predictions for GDP growth, which are, however, overshadowed by a reduced sample size. views this thesis author not necessarily supervisor,
A report of 42 unrecorded actinobacterial species in Korea

actinobacteria are generally described as aerobic, high-G + c-content, Gram-staining-positive bacteria and contain morphologically diverse groups that ranged from coccoids or rods to hyphal forms. The branched, filamentous hyphae may either remain stable or split into smaller fragments (lechevalier & lechevalier, 1981). in many mycelium-forming actinobacteria, the hyphae are differentiated into aerial mycelia, as well as vegetative mycelia, that bear spores that may by located on the tips of filaments or inside sporangia (lechevalier, 1989; ensign et al., 1992; prescott et al., 2002). The phylum Actinobacteria (ludwig et al., 2012) consists of classes Actinobacteria, Acidimicrobiia, Coriobacteriia, Nitriliruptoria, Rubrobacteria and Thermoleophilia based on 16S rrna gene sequences. among these, the class Actinobacteria contains 15 orders: Actinomycetales, Actinopolysporales, Bifidobacteriales, Catenulisporales, Corynebacteriales, Frankiales, Glycomycetales, Jiangellales, Kineosporiales, Micromonosporales, Micrococcales, Propionibacteriales, Pseudonocardiales, Streptomycetales and Streptosporangiales. Members of these bacteria are widely distributed in nature and occur in both terrestrial and marine habitats such as soil, fresh or sea water, plants, insects, Journal of Species Research 7(1):36-49, 2018
