A Quantitative Survey of Twitter's Influence on Online Business
Authors: Sipos Dario
Published: November 2023

The advancement of technology and people's interactions virtually over social media has created many opportunities for online businesses to expand their scope and maintain their cost efficiencies by targeting customers on social media platforms. Twitter is one of the businesses’ actively used social media platforms to reach customers. Businesses seem to shift their scope more towards the online side because this is where they can reach customers. Social media platforms facilitate businesses in reaching out to customers and developing their brand image through marketing strategies. The features that attract users towards using Twitter are the word-of-mouth communication generated on it and the freedom of expressing and sharing opinions. This paper investigates how Twitter has played its role in shifting the scope of businesses online and developing their brand image using it as a platform. Additionally, it aims to ascertain how online business activities have impacted customers on Twitter. We used the quantitative method to discover the influence of Twitter activities on online business, and data were collected from 80 respondents. The results have been further analysed using the Likert scale analysis, and to determine the relationship between the variable and to test the hypotheses, multiple regression has been used. The study's results showed a significant relationship between the business's engagement online on Twitter and the customer's loyalty to the brand.
”Varför tycker du man ska ha dödsstraff, då?” Ett sociologisk-didaktiskt verktyg för analys av klassrumsdebatter
Authors: Norlund Anita
Published: November 2023

Debates, as the discursive curriculum activities they are, are occasionally arranged in classrooms. Here, the aim is to offer a tool for analyses of such activities. By adopting a sociological‐didactical perspective, this article takes Basil Bernstein’s conceptual pair vertical and horizontal discourse as its starting point. The ‘vertical discourse’ is roughly speaking school‐oriented whereas the ‘horizontal discourse’ is more often played out in informal contexts. These two central concepts will be specified in particular relation to the classroom debate as curricular content. Two contrasting authentic classroom debates were intentionally selected in order to try out the analytical tool. Both the debates deal with the same topic, i.e. death penalty. The debates, however, also differ from each other; they are put into practice in remarkably different ways and in different contexts, although they are both collected from, in a sociological perspective, supposedly less advantaged areas. I argue that the tool offered is a needed and fruitful way of capturing what happens in classroom debates.

The biocomposite foam made from tapioca and glucomannan still has weaknesses such as hydrophilicity and low mechanical strength. This research aimed to determine the effect of polyvinyl alcohol and magnesium stearate concentrations on the characteristics of biocomposite foam made from tapioca and glucomannan, as well as to determine the optimal concentration of polyvinyl alcohol and magnesium stearate to produce the best characteristics of the biocomposite foam. This study used a randomized group design with two factors. Factor I was the concentration of polyvinyl alcohol consisting of three levels, namely 20%, 30%, and 40%. Factor II was the concentration of magnesium stearate consisting of three levels, namely 10%, 15%, and 20%. The variables observed were tensile strength, density, tear resistance, fixed compressive strain, thickness, thickness expansion, and biodegradation time. The data obtained were analyzed for their variability and followed by Duncan's test. The results showed that the concentration of polyvinyl alcohol and magnesium stearate had a very significant effect on tensile strength, tear resistance, fixed compressive strain, swelling, and biodegradation, but had no significant effect on density and thickness. The interaction between treatments had a very significant effect on tensile strength, tear resistance, fixed compressive strain, and biodegradation, but had no significant effect on density, thickness, swelling, and biodegradation time. The optimal concentration of polyvinyl alcohol was found to be 40%, and the optimal concentration of magnesium stearate was found to be 20%, which resulted in the best biocomposite foam with a tensile strength of 2.10 N/cm2, tear resistance of 1.50 N/cm2, density of 0.40 g/ml, fixed compressive strain of 2.89%, thickness of 3.59 mm, swelling of 0.61%, and biodegradation time of 17.33 days

Indonesia is known as a country that has a high biodiversity, but the available data are still very limited. One of the biodiversity that is owned by Indonesia is Kesambi (Schleichera oleosa). This plant has considerable potential, therefore supporting data is needed for further development both for the benefit of medicinal plants and for others. Anatomical character identification research aims to determine the important characteristics of plant species originating from various growing habitats. The anatomical characters of the leaves observed included xylem and phloem thickness, cuticle thickness, epidermal thickness, trichome type, average trichome length, stomata type, stomata length and width. Based on the results of the study, it can be concluded that the Kesambi tree that grows both in the lowlands and highlands in Malang City and in Nganjuk Regency has the same anatomical character, namely the type of trichomes and stomata. While the other characters show differences in size. The higher the place where the kesambi tree grows, the thinner the phloem and xylem on the stems are observed. While the other parameters did not show the pattern formed on the size of the characters observed in both the leaves and stems.

Lipid Profile Of Wistar Rat (Rattus norvegicus Berkenhout, 1769) With Ulva lactuca L. Treatment
Authors: Islahi Annisa Nur , Mulyati Mulyati
Published: November 2023

Lipid profile is an overview of lipids in the blood that can be used as an indicator of cardiovascular disorders. Changes in lipid metabolism can be caused by modification of lipid and lipoprotein that are correlated with free radical production. Free radicals can be induced by various things including heavy metal contamination. In a previous study, it was stated that heavy metals levels in Ulva lactuca L. originating from the coast in Gunung Kidul were above the threshold value by BPOM for vegetable foods. There was an attempt to decontaminate heavy metals in Ulva lactuca L. by immersing the thallus of Ulva lactuca L. using bilimbi fruit sequestrant. These attempts were made to improve the quality of Ulva lactuca L. so it becomes safe for consumption and has a positive effect on the physiology, especially the lipid profile. This research aimed to determine the lipid profile of white rats (Rattus norvegicus Berkenhout, 1769) after being treated with Ulva lactuca for 30 days. In this research, after obtaining Ethical Clearance with No.00020/04/LPPT/VII/2022 12, white rats 10 weeks old were divided into 3 groups each comprise four rats, i.e. group I (control), group II (treatment of natural Ulva lactuca), and group III (treatment of Ulva lactuca decontamination). Data on total cholesterol, triglyceride, LDL-C, and HDL-C levels were analyzed using one way ANOVA at 95% confidence interval. The results showed Ulva lactuca treatment at 1000 mg/kgBW/day for 30 days could decrease triglyceride, cholesterol total, LDL, and HDL levels in white rats (Rattus norvegicus Berkenhout, 1769) Wistar strain with the highest decrease occurring in triglyceride levels.

Published: November 2023

Pollution of fat waste into the aquatic environment originating from industrial food processing, restaurants and kitchens or by accidental oil spills is currently being found more and more. PUPS results for 2020 found 3 bacterial strains, namely Bacillus licheneformis, Bacillus coagulan and Pseudomonas diminuta. The microbial consortium is a mixture of microbial populations in the form of communities that have cooperative, commensal, and mutualistic relationships. Field tests need to be carried out to test whether the results of the degradation of fats and oils from the three bacteria above can be applied to waste fats and oils in the environment. The purpose of this study was to find media formulations and proper applications from molasses-based bacterial consortia and to determine the effectiveness of molasses-based media formulations. This study used the Sequence Batch Reactor (SBR) method, physical, chemical and biological parameters including measurement of total fat, Dissolve Oxygen/DO Test, BOD5 Test (Biological Oxygent Demant), Nitrate Test, Nitrite Test Total dissolved solids (Total dissolve solid/TDS), and TPC Microbial Count, (Total Plate Count). The results showed a decrease in the treatment of bacterial consortium of 80 ml/2lt (40 ml/lt) of waste fats and oils on measurements of BOD5, TDS, total fat, nitrite and nitrate and the bacterial population remained high on the 5th day after treatment. This study demonstrated the ability of a molasses-based bacterial consortium to be used as a starter agent for processing fat waste in an environment polluted by fat and oil waste.
Role of Catecholamine Hormone to Increase the Virulence of Aeromonas hydrophila
Authors: Widiantari Ni Putu , Ramona Yan , Julyantoro Pande Gde Sasmita
Published: November 2023

Extreme environmental conditions have been widely reported to trigger stress in exposed living organisms, and such conditions affect their homeostatics. Sress conditions lead vertebrates to release stress hormones, such as catecholamine Norepinephrin (NE) and Dopamine (Dopamine), which involve the hypothalamus-sympathetic-chromaffin (HSC) axis and the hypothalamus-pituitary-interrenal axis (HPI axis). These two axis systems produce catecholamine hormones (including adrenaline, noradrenaline, and dopamine) and corticosteroid hormones (especially cortisol). The presence of these two groups of hormones in the circulatory system of the hosts can act as a signal for pathogenic bacteria, such as Aeromonas hydrophilla commonly found in aquaculture, to start their infection process. These two types of hormones play a role in the expression of Aeromonas hydrophila genes encoding formation of flagella (allowing bacterial cells to swim rapidly to their host), pilli, toxin production, and activation of biofilm formation process. The stress conditions experienced by fishes (which triggers the secretion of catecholamine hormones) can significantly reduce the fish's immune system to function, and this will be exploited by Aeromonas hydrophila to increase its metabolic rate, growth, and virulence in such stressed fish. Specifically, catecholamine hormones can also act as a signal for the Aeromonas hydrophila to activate the ferric uptake regulator gene (fur gene), allowing this pathogenic bacterium to optimally chelate ions of iron (Fe3+) from its environment, resulting in the excessive growth of the pathogen and an increase in its pathogenicity.

Reactive voltage control strategy of distribution network considering the reliability of photovoltaic power supply
Authors: Liang Jifeng , Li Tiecheng , Zhang Rui , Dong Liangyuan
Published: November 2023

Photovoltaic power actively regulates the reactive power of the active distribution network, leading to the increase of output current of the photovoltaic inverter. Consequently, the temperature rise significantly impacts the maximum junction temperature of the Insulated Gate Bipolar Transistor (IGBT), leading to fluctuations in the junction temperature. To realize the active support of the reactive power of the photovoltaic power supply and ensure its reliable operation, a reactive voltage control strategy of the active distribution network considering the reliability of the photovoltaic power supply is proposed. Considering the reactive power support capability of the distributed photovoltaic power, a multi-objective reactive power optimization model for active distribution networks is established based on IGBT maximum junction temperature, distribution network losses, and photovoltaic active power reduction. The effectiveness of the proposed strategy in enhancing the minimum lifetime, average lifetime, and reliability of photovoltaic power sources is verified using the IEEE 33-node standard distribution system. The results show that under the strategy proposed in this paper, the average junction temperature and junction temperature fluctuation of IGBT are effectively reduced, and the minimum lifetime and average lifetime of all IGBTs are increased by 8 years and 4 years respectively.

Production practices and processing for value-added goat meat,
Authors: McMillin K. W. , Brock A. P.
Published: November 2023

This review discusses adding value to goat meat, with an emphasis on the properties of goat meat and processed products. Goat meat value may be increased through production practices or meat processing. Decreasing the market channel steps or distribution costs and marketing animals in uniform or consistent groups will generally increase live animal value. Processing of meat into more palatable and usable forms or providing meat at times of higher purchaser demand will usually increase the price of the meat. Age, breed, and diet influence tenderness, juiciness, and flavor, with higher fat in carcasses and cuts from goats fed concentrate diets. The meat from kid and yearling goats of low conformation could be distinguished by goat meat consumers from the meat of goats with medium and high conformation. Ethnic groups that purchase goat meat have high levels of population growth and are increasing their buying power. Higher income populations desire value-added food products, which have been changed in form, function, or grouping to increase their economic value and/or appeal; however, lower income groups have a supply of imported frozen goat meat at a price lower than domestic sources. Food service operations purchase uniform cuts and sizes of meat, which are provided through USDA Institutional Meat Purchase Specification descriptions for goat meat. Goat meat also may be processed with unit operations similar to those for other meat species. Tenderness of domestic goat meat was improved with postmortem goat carcass aging, electrical stimulation of goat carcasses, and blade tenderization of goat cuts. The addition of α-tocopherol increased the oxidative stability of goat meat patties, whereas the addition of oat trim or oat bran decreased fat and shear force. Smoked and fermented goat meat sausages were acceptable to consumers, but they are more expensive per unit weight than sausages from other species. Emulsification capacity of goat meat proteins is high, and the palatability of frankfurters was increased with the use of mechanically separated goat mince. Goat meat was distinguishable from other species in plain and seasoned meat loaves, chili, curries, and patties. Specific organic acids are associated with goat meat flavor, and oxidized flavors develop more rapidly in cooked goat meat than in meat from other species. More convenient product forms and the availability of goat meat would increase the value and penetration of goat meat in ethnic and nontraditional consumer markets.

In dieser Arbeit wird untersucht, in wieweit sich Prozesse des Dokumentenmanagements in zwei Low-Code Plattformen abbilden lassen, wenn die eigentlichen Funktionen des Dokumentenmanagements uber ein Backend in Form eines SAP-ERP Systems in mittels Services implementiert werden. Insbesondere soll die Art der technischen Anbindung zwischen den jeweiligen Plattformen und dem Backend untersucht werden; speziell das Zusammenspiel zwischen Funktionen in Front- und Backend. Ein weiterer Aspekt der Fragestellung ist dann auch wie die Low-Code Plattformen die Entwicklung der Funktionen des Dokumentenmanagements und deren Einbettung in den Geschäftsprozess unterstützen, was insbesondere auch durch einen Prototypen validiert werden soll. Als Untersuchungsgrundlage dienen die beiden Low-Code Plattformen Bizagi und Mendix. Es wurde ein Prozess des Dokumentenmanagements betrachtet, da hier die Parametrisierung der Aufrufe zum Backend besonders komplex sind, denn es sind statt der sonst üblichen Parameter (z.B. Werke, Materialnummern und Kunden) die Identikation der Dokumente und dabei insbesondere auch Originale der Dokumente zu ubertragen - somit ist das hier Untersuchte leicht auf einfachere Falle von Backend Services übertragbar.
Vibrational spectra of highly anharmonic water clusters: Molecular dynamics and harmonic analyses revisited with constrained nuclear-electronic orbital methods
Authors: Zhang Yuzhe , Wang Yiwen , Xu Xi , Chen Zehua , Yang Yang
Published: November 2023

Vibrational spectroscopy is widely used to gain insights into structural and dynamic properties of chemical, biological and material systems. Thus, an efficient and accurate method to simulate vibrational spectra is desired. In this paper, we justify and employ a microcanonical molecular simulation scheme to calculate the vibrational spectra of three challenging water clusters: the neutral water dimer (H4O2), the protonated water trimer (H7O3+), and the protonated water tetramer (H9O4+). We find that with the accurate description of quantum nuclear delocalization effects through the constrained nuclear-electronic orbital framework, including vibrational mode coupling effects through molecular dynamics simulations can additionally improve the vibrational spectrum calculations. In contrast, without the quantum nuclear delocalization picture, conventional ab initio molecular dynamics may even lead to less accurate results than harmonic analysis.

In a recent paper [J. Phys. Chem.B 127, 7983-7987 (2023)] , we have shown that for molecular dynamics (MD) simulations using orthorhombic periodic boundary conditions with "magic" box length ratios of $L_z/L_x=L_z/L_y=2.7933596497$, the self-diffusion coefficients $D_x$ and $D_y$ in $x$- and $y$-direction are independent from the system size. They both represent the true self-diffusion coefficient $D_0=(D_x+D_y)/2$, while the shear viscosity can be calculated from diffusion coefficients in $x$-,$y$- and $z$-direction, using $\eta=k_\mathrm{B}T\cdot 8.1711245653/[3\pi L_z(D_{x}+D_{y}-2D_z)]$. In this contribution, we test this "OrthoBoXY"-approach by its application to a variety of different systems: liquid water, dimethyl ether, methanol, triglyme, water/methanol mixtures, water/triglyme mixtures, and imidazolium based ionic liquids. The chosen systems range from small-sized molecular liquids to complex mixtures and ionic liquids, while spanning a viscosity range of almost three orders of magnitude. We assess the efficiency of the method for computing true self-diffusion and viscosity data and provide simple formulae for estimating the required MD simulation lengths and sizes for delivering reliable data with targeted uncertainty levels. Our analysis of the system-size dependence of statistical uncertainties for both the viscosity and the self-diffusion coefficient leads us to the conclusion that it is preferable to extend the simulation length instead of increasing the system size. MD simulations consisting of 768 molecules or ion pairs seem to be perfectly adequate.

Nanosized cerium oxide (CeO2) has been extensively used as an oxygen storage component in automotive emission control systems. However, the possible involvement of atomically dispersed cerium (Ce) has not been explored. Here, we demonstrate the controllable transformation of CeO2 nanoparticles into isolated Ce1 cations on the surface of gamma-type alumina (γ-Al2O3) via reductive atom trapping, achieving over half-monolayer coverage. Supported single-atom rhodium (Rh1) surrounded by dispersed Ce1 shows superior performance to Rh1 on bare Al2O3 or crystalline CeO2 in catalyzing NO reduction, exhibiting a striking one-order-of-magnitude increase in turnover frequency. Dispersed Ce1 also exhibits greatly enhanced oxygen transfer capability and introduces a modified reaction mechanism that involves adjacent Rh1-Ce1 dual-sites, resulting in a greatly decreased activation barrier (96 vs. 192 kJ/mol). The understanding of reductive atom trapping of Ce1 as well as its structure-property relationships obtained in this work could be implemented in the rational design of Ce1-promoted catalysts for many other applications. Benefiting from the greatly enhanced OSC, activity enhancements are also seen with Ce1-promoted platinum nanoparticles for the oxidation of CO and hydrocarbons. Additionally, dispersing Ce1 on Al2O3 results in modified surface properties, which could be further utilized to explore the field of acid-base catalysis
A contribution to the systematics of Xylopia (Annonaceae) in the New Guinea region
Authors: Johnson D.M.
Published: November 2023

In the New Guinea region, including the Solomon Islands and Halmahera, three species of the pantropical genus Xylopia L. have been previously recognised: X. calosericea Diels, X. papuana Diels, and X. peekelii Diels. In recent floristic tabulations the genus has thus comprised a minor component of the Annonaceae flora. Here we present descriptions and illustrations of 14 new species of the genus from the region: Xylopia aenea D.M.Johnson & N.A.Murray, X. ampla D.M.Johnson & N.A.Murray, X. brunneola D.M.Johnson & N.A.Murray, X. bullata D.M.Johnson & N.A.Murray, X. chlorosperma D.M.Johnson & N.A.Murray, X. cornuta D.M.Johnson & N.A.Murray, X. corrugata D.M.Johnson & N.A.Murray, X. makiraensis D.M.Johnson & N.A.Murray, X. musella D.M.Johnson & N.A.Murray, X. pachysericea D.M.Johnson & N.A.Murray, X. rogstadii D.M.Johnson & N.A.Murray, X. sulangwane D.M.Johnson & N.A.Murray, X. takeuchii D.M.Johnson & N.A.Murray, and X. vulcanicola D.M.Johnson & N.A.Murray. We distinguish the 17 species in a diagnostic key. The region includes Xylopia species that are among the tallest in this genus of c. 220 species, one with the largest leaves and another with the largest fruit, as well as several species with distinctive cataphyll-covered resting buds. The genus has undergone multiple dispersals both to and within the region, with higher diversity on smaller islands than on New Guinea. Its presence on oceanic islands indicates over-water dispersal.

Published: November 2023

Background: End-stage renal disease is the final stage of chronic kidney disease in which irreversible deterioration in renal function occur and the body fails to maintain fluid and electrolyte balance, this need regular hemodialysis (HD) a process that removes accumulated solute from a patient with near-total renal function loss. Arteriovenous fistula (AVF) is the vascular access of choice for patients who require hemodialysis. AVF thrombosis is a major issue in hemodialysis patients, which increase their morbidity and lessen HD efficiency. Objective: To assess plasma level of ADAMTS-13 in HD patients and its association with AVF thrombosis, and to correlate the plasma level of ADAMTS-13 with age, duration of dialysis, certain hematological parameters and estimated GFR. Patients and Methods:This Cross_sectional study done on 60 patients with ESRD on regular HD sessions, 20 healthy persons were included as a control . The patients subdivided into two subgroups with and without AVF thrombosis. Plasma samples were freezed until the test for the level of ADAMTS-13 was done. Results: The plasma ADAMTS-13 level was significantly lower in HD patients compared to control group (P < 0.001), and was a significantly lower in patients with a history of AVF thrombosis than HD patients without a history of AVF thrombosis. HD patients with AVF thrombosis had significantly lower eGFR compared to patients without a history of AVF thrombosis. There was a positive correlation of plasma ADAMTS-13 level with the mean of eGFR , platelet count and negative correlation with MPV. Conclusion: Significant differences between HD patients and control regarding eGFR and hematological parameters . Plasma ADAMTS-13 level was significantly lower in patients compared to controls and significantly lower in patients group with AVF thrombosis than HD group without thrombosis.

Published: November 2023

Background: Iraq had the third-greatest neonatal mortality rate in the Middle East in 2021 with 14 fatalities per 1,000 live births. Objective: To investigate factors contributing to poor outcomes in the neonatal intensive care unit. Patients and Methods: A retrospective cohort study conducted between 1 April to 31 September 2022 involved 632 neonates. Required data and outcomes were collected using predesigned forms. Results: The mortality rate in NICU was 23.9%, with 64.9% of deaths occurring within the first six days. The overall mortality rate was 38.5 per 1000 live births. Deceased neonates had significantly lower gestational age and birth weight (P<0.001). Prematurity, respiratory distress syndrome, and congenital anomalies contributed to 94%, 73.5%, and 20.5% of deaths respectively. Mortality was significantly higher in patients with RDS 111(56.3%; P<0.001), pulmonary hemorrhage nine (100%; P<0.001), sepsis 26 (74.3%; P<0.001), and chorioamnionitis nine (100%, P=0.002). Newborns delivered vaginally had a 4.11 times higher likelihood of poor outcomes compared to cesarean deliveries. Conclusion: Most NICU deaths resulted from prematurity and respiratory distress syndrome. Enhancing healthcare personnel skills, standardizing protocols, and evidence-based practices for preterm and respiratory 0distress syndrome management can help reduce neonatal mortality rates in Iraq.
