Authors: Irwan Mahakam Lesmono Aji  , Syaputra Maiser Syaputra
Published: June 2023

Sugar palm (Arenga pinnata), a multi-purpose tree species (MPTS), has significant ecological and economic benefits. However, the imbalance between the benefits of this plant and its development is a concern. After reaching 50 years of age, the sugar palm tree can no longer reproduce, necessitating the need for cultivation. The primary challenge in cultivating this plant is its hard seed coat. While acidic ingredients have been used to break seed dormancy, natural ingredients are not commonly utilized. This study employed an experimental method with a completely randomized design (CRD). The study design included three factors: maturity level (K), soaking solution treatment (B), and soaking time (L). The parameters assessed in this study were maximum growth potential, germination capacity, leaf length, leaf area, number of leaves, stem diameter, stem length, primary root length, number of roots, and apical shoot length. The results indicate that soaking treatment did not significantly affect the parameters, except for root length. The maturity level treatment also did not significantly impact the parameters. However, K2 seeds (uniform yellow) showed better results in all parameters than other maturity levels, and B3 (100% coconut water) was the soaking solution that yielded positive results

OF ELEMENTS IN SOLID SAMPLES
Authors: Oreshkin Valentin N. , Tsysin Grigory I.
Published: June 2023

A design is proposed for a crucible electrothermal atomizer with a vertical arrangement of evaporation, condensation, and atomization zones in graphite cylindrical blocks with transverse heating. In such a cylindrical column, heat treatment was carried out – the evaporation of a solid sample and the condensation of vapors, and then the evaporation of the condensate into the atomization zone, in which vapors are filtered through the porous medium of the graphite filter into the analytical zone. Due to the separation of matrix components and the reduction of interference, the metrological characteristics of the determination of elements in solid organomineral samples are improved.

To determine the effect of the surface potential of dielectric samples on the yield of positive ions during
ion irradiation, we studied the dependence of the current of secondary particles on the thickness of dielectric
films. It is shown that the yield of positive secondary particles increases significantly with increasing thickness
if the film charging potential does not exceed the breakdown value determined by the electrical strength of
the film. An indirect confirmation of the film charging in these experiments is the time dependence of the
current from the sample holder. An experimental evaluation of the apparatus effect caused by the emission of
secondary electrons from a hemispherical collector has been carried out. Possible mechanisms of the observed
phenomena are discussed.

Published: June 2023

Vegetais minimamente processados são produtos de praticidade submetidos a um processamento por meio de operações unitárias que podem levar a uma rápida deterioração do produto. Nanoemulsões (NEs) são sistemas heterogêneos formados a partir de dois líquidos imiscíveis em que um líquido se encontra disperso no outro em pequenas gotículas, estabilizadas por tensoativos, as quais podem ser utilizadas como nanocarreadores de diferentes compostos. O objetivo desta revisão é apresentar os avanços na utilização de NEs na conservação de vegetais minimamente processados. Além disso, serão abordados tópicos envolvendo composição, métodos de obtenção, caracterização, propriedades e estabilidade de Nes. Em geral, os métodos mais utilizados para a obtenção das NEs foram homogeneização a alta pressão e ultrassonicação. Os estudos demonstraram redução microbiana, controle do escurecimento, menor redução da firmeza e da perda de massa, bem como redução da taxa respiratória nos vegetais minimamente processados revestidos com diferentes NEs, não apresentando impactos indesejáveis nos atributos sensoriais como cor e aparência. A aplicação de NEs contendo compostos antioxidantes e antimicrobianos em vegetais minimamente processados torna-se uma alternativa promissora para preservar as características destes produtos.

Published: June 2023

Purpose: libraries may become obsolete in the twenty-first century unless they begin to harness new technology and improve information and service delivery. This paper examines the potential application and implications of artificial intelligence for contemporary library services in Nigeria. Methods: this paper adopts the expository research approach to evaluate the application and implication of artificial intelligence in contemporary library services in Nigeria. Through systematic analysis of literature, the study addresses how academic libraries can utilize artificial intelligence to support innovative library services.  Findings: the column emphasizes that, academic libraries in Nigeria have not yet adopted and applied AI, in spite of the potential that it holds for libraries. Given that there has been relatively little study linking artificial intelligence (AI) to librarianship, this may be because there is a low degree of awareness and adoption of AI's importance in libraries.Conclusions: this column is the original idea from the authors and does not reflect on any copyrighted materials. The column recommended that, academic libraries in Nigeria should fully embrace artificial intelligence like chatbots, barcodes, RFIDs, and robots for delivering quality services and libraries should also leverage on the opportunities presented by artificial intelligence to reconnect their remote users, and consequently re-establish their relevance among the user community

Context: Ruta angustifolia Pers. has been used as a traditional herb among counties. The ethanol extract of R. angustifolia has proven active as an anti-hepatitis C virus in vitro. Due to the potency of this plant, a safety evaluation is necessary. Aims: To examine the acute and sub-chronic toxicity of ethanol extract of R. angustifolia leaves in rats. Methods: An acute toxicity study was done by treating 70% ethanol extract of R. angustifolia (doses of 5, 50, 300, and 2000 mg/kg of BW), while the control group received 1% Tween-80. Toxicity signs and mortality of rats for 14 days were observed. While sub-chronic (28-days repeated dose) toxicity was evaluated with 4 groups, both males and females. The three groups were treated with 70% ethanol extract of R. angustifolia at doses of 50, 500, and 1000 mg/kg BW daily for 28 days, and one group served as a control group. Biochemical, hematological, and histopathological parameters were measured after the period of treatment. Results: The acute toxicity was no demonstrated toxicity signs or mortality effects up to 14 days of the experiment. Therefore, the LD50 value of the extract was estimated to be higher than 2000 mg/kg BW. The sub-chronic assay revealed no mortality and toxicity effects, including behavior parameters, relative body weight, hematology, and biochemical at 50 and 500 mg/kg BW doses. However, a significant change was seen in the testis of all doses and the liver of the male rats treated at 1000 mg/kg BW. Histopathology assay observed the presence of activated Kupffer cells, sinusoidal dilatation, and infiltration of lymphocytes at the portal vein in the liver with 1000 mg/kg BW. Those may indicate possible toxicity in the liver at the dose of 1000 mg/kg BW. However, no toxic effect at the lower doses tested. Conclusions: These results suggest that the use of Ruta angustifolia leaves ethanolic extract is relatively safe. The application of high doses needs to be evaluated.

"Establishing the technology for hot processing of some steels with special destination is connected in the first place to defining the warming conditions, depending on their technological characteristics. The choice of optimal regime is made, most of the times, relying on the practical experience because the analytical calculation methods give relative alues. This paper proposes to compare the data obtained from industrial experiments with theoretical calculation methods for their approximation. The key innovation introduced in this paper is represented by analytical solutions to determine the evolution of the ingot mass temperature. We focused on presenting an analytical solution to determine the evolution of temperature in the ingots’mass and comparing it with the data resulted from experiments. The proposed analytical procedure successfully substitutes for hard-to-perform experiments, in conditions of the current practice. The usage of the proposed mathematical technique also assures the shortage of the total heat duration with economic effects generated by the reduction of fuel quantity and by the increase of productivity of the deep furnaces.

"Low head hydro power plants are generally plants equipped with Kaplan or bulb turbines.They can process a discharge of the order of tens of m3 /s (Fughiu HPP, Zăneşti HPP, Golesti HPP) or hundreds of m3/s (Ipoteşti HPP, Robeşti HPP) and have a gross head generally between 10 ... 30 m. In order to make a good determination of the efficiency of a hydro unit that equips a low head hydro power plants, it is necessary to perform performance tests periodically by measuring the actual operating parameters of the hydro unit in situ. Among the parameters of a hydro power or hydro-unit, the parameter whose measurement poses the most difficult problems is the turbine discharge. Determining the turbine discharge requires a complex measurement methodology. The present paper aims to present and analyze the main methods of determining the discharge that can be used in the case of low head small hydro power plants. "

A new definition of the measure units in Physics by using the concept of cardinal number and by considering universal physical constants is proposed. Another idea is to start from the moment of the creation of the Universe (BIG BANG or better said BIG FLASH). n this way, along with the speed of light in vacuum CV, the Planck constant h and the total energy of the Universe, EU are introduced. As regards the measure unit for temperature, the Boltzmann constant kB is considered. For the electrical charge, the electron charge is taken as a constant. In this way the sustenability of evaluation of technical parameters is increased. For example, the lowest sustenability is for unitts like (feet;pounds) instead of (meters; kgs).

Catalytic ozonation of the azo dye Acid Yellow 23 was investigated in the presence of Montmorillonite K10 and its chemically modified counterpart with Cobalt and Nickel (Co-Ni-K10). The material thus obtained were characterized by BET, XRD and TGA analysis. The effects of different variables were studied, such as: catalyst dose, ozone dose, ozonation time and pH. Clay-catalysed reactions are strongly dependent on the adsorption of the reactant, which in turn should depend on acid-base, electrostatic and hydrophilic-organophilic interactions. The basicity of the clay catalyst surface is expected to favour the interactions with the acidic groups of the studied organic molecule. The interactions involved in adsorption are determined by the pKa values of each group in each organic molecule.

Solvent extraction process is frequently used to obtain chemical compounds used in the nuclear field. In order to make nuclear energy a safe, clean and cheap energy source, one has resorted to the identification of new, innovative methods in the immediate transfer of the laboratory results to an industrial scale. A method is described for the design of liquid extraction columns by scaling up from the results of small scale plant tests. Such a method was applied for scaling up a pulsed column with sieve trays using the dimensions of an experimental model column. The scale-up method is based on the assumption that the height of the column is independent of column diameter, and that increased backmixing accounts entirely for differences in performance on small and large scales. This paper uses the results obtained on an experimental model column for the purpose of designing a high capacity column. The final result consists in determining the diameter and height of a scaled up column by using like parameter the number of transfer units corresponding to a compartment, a value that will stay the same for the laboratory-scale column and for the large-scale (pilot or industrial) column.

Background: The precise identification of attention deficit-hyperactivity disorder (ADHD) is one of the challenging clinical processes. Disorganizations in functional neural networks revealed via functional magnetic resonance imaging have recently been contributing. Machine learning approaches, particularly classification methods, have commonly been employed as a framework for diverse data analysis, indicating promising medical diagnosis results. However, as the neuroimaging data are high-dimensional with a low sample size (the current dataset), this study aimed to evaluate the classification performance of the models by considering the specific contribution of the sparsity of data matrices. Methods: This cross-sectional study analyzed the preprocessed data from the 2011 ADHD-200 Global Competition. A total of 768 and 171 data items were considered training and test, respectively. The diagnosis status was used as a response variable. Age, gender, hand dominance, and activity relationship between 116 brain regions derived from inverse covariance matrix and inverse sparse covariance matrix were used as predictive variables. Accordingly, this study compared the performance of three models, namely support vector machine (SVM), distance-weighted discrimination (DWD), and data maximum dispersion classifier (DMDC) for ADHD categorization. Results: The highest value for the total accuracy was reported for the SVM model on the sparse covariance matrix. Moreover, the highest values for the balanced classification rate (BCR) (59%) and sensitivity (64%) were reported for DMDC on the sparse covariance matrix. The best level of specificity (99%) was obtained from DWD using the sparse covariance matrix. The highest levels of the values (i.e., total accuracy and BCR) were achieved through the model fitting on the sparse matrices. Among the six models, the DMDC model on sparse covariance matrix was the most optimal algorithm due to the superiority of the two indices (i.e., accuracy: 60% and BCR: 60%) and the favorable balance between sensitivity and specificity values. Conclusions: Among the current studied three models, DMDC performance, applying the sparse data, remarkably improved the results of classification processes. Based on the present findings, the neuronal connectivity among subcortical structures comprising parts of the basal ganglia and cerebellum provides a distinction between ADHD subjects and healthy controls.

Introduction: Fibrocartilaginous embolic myelopathy is a non-progressive injury in the spinal cord that can cause infarction in veins of spinal parenchyma which leads to ischemia and necrosis.

Case report: Fibrocartilaginous embolic myelopathy was diagnosed in a 4-year-old, female, Spitz dog using the clinical neurological examination. The dog was hospitalized, and the treatment including supportive treatment and Cortone was set up for three weeks. Then Diazepam and Methocarbamol were added to the prescription and treatment continued for two weeks. A general improvement was noted after three weeks, and the dog could stand perfectly after 5 weeks.

Conclusion: Three weeks of supportive treatment, Cortone therapy as well as the addition of Diazepam and Methocarbamol to the treatment could help the dog to stand on its feet. However, cannot be ignored that knowing about the history of the dog played an important role in its treatment procedure.
