Published: July 2021

Currently, companies are required to improve supply chain performance. One of the main problems in the supply chain is the proper supplier selection. Supplier selection has an essential role in improving supply chain management performance. Supplier selection requires the proper criteria. However, the relationship between criteria is rarely considered in the selection of suppliers in the textile industry. This study tries to propose integrating the Decision Making Trial and Evaluation Laboratory (DEMATEL) and the Analytic Network Process (ANP) for supplier selection in the textile industry. Both methods are multi-criteria decision making (MCDM) tools DEMATEL is used to assess the relationship between criteria. Furthermore, ANP is used to evaluate and weigh the importance of criteria and suppliers. A case study was carried out in a textile company located in Indonesia. The results show that this procedure can identify the relationship and effect of each criterion. The results show that the product price criteria are the criteria that have the most significant weight. The criteria for conformity to specifications and consistency of quality are in second and third place. Finally, suppliers are selected based on weight assessment on each criterion by ANP.

Mangrove plants as traditional medicine have long been used by the society for the therapy of anticancer diseases. So far, the potency of mangrove plants as anticancer has not been studied intensively. The methanol extract of R. mucronata stem bark has cytotoxic activity on myeloma cells. This study aims to determine the isolates of the ethyl acetate fraction of the methanol extract of the stem bark of R. mucronata and R. apiculata, and to examine the potency of cytotoxic activity against MCF-7 and T47D cells. The powder of the stem bark of R. mucronata and R. apiculata were extracted with methanol by maceration, and then the methanol extract was fractionated consecutively using n-hexane, ethyl acetate, and methanol. Ethyl acetate fraction was then purified by column chromatography with a diameter of 2 cm and a height of 30 cm with a static phase in the form of silica gel 60 (0.063-0.2 mm) Merck 7734 and eluent n-hexane:ethyl acetate (6: 4, 5: 5, 6: 4, 7: 3, 8: 2, 9: 1) and n-hexane: methanol (9,5: 0,5) 10 ml each. The eluates that produce the same number and pattern of stains were combined into one isolate. Then the eluate was evaporated at room temperature. Then the purification results of the extract R. mucronata were isolated using preparative TLC with 0.25 mm GF254 silica gel as static phase and n-hexane mobile phase: ethyl acetate (6: 4), while the apiculata extract with n-hexane mobile phase: ethyl acetate (5: 5). The results of the stain separation of the compound were scraped off and separated from the static phase using a solvent. The purity of isolates compound was examined using TLC in the static phase of silica gel GF254 0.25 mm. The qualitative test results of the ethyl acetate fraction of R. apiculata stem bark with an NMR spectrophotometer showed a composition of cis-3- (3,5-dihydroxyphenyl) acrylic acid, while the ethyl acetate fraction of R. mucronata stem bark contained n-hexan-3-ol compounds. The cytotoxicity test of ethanol extract, n-hexane fraction, ethyl acetate fraction and ethanol extract was carried out on MCF-7 and T47D cells using the MTT method. The results proved that the ethanol extract, n-hexane fraction, ethyl acetate fraction and ethanol fraction from the ethanol extract of R. mucronata and R. apiculata stem bark, based on cytotoxic activity, were inactive against MCF-7 and T47D cells.

Cosmetics that are sold in the market are in great demand by many women. The type of cosmetics that is often used is a whitening cream. This cream can provide a whitening effect on facial skin so that it can increase self-confidence. One of the ingredients that have skin whitening properties and is often added to whitening creams is hydroquinone. This material has the effect of inhibiting the formation of melanin so that it can whiten the skin. The use of hydroquinone without medical supervision is not allowed because it can have negative effects such as allergies, skin redness, and a burning feeling. In this paper, we will report the identification results of the hydroquinone content in the whitening cream which is not a distribution license number from the BPOM (Indonesia Food and Drug Supervisory Agency) which is marketed in the Banjarnegara Region area. Samples were taken from the Banjarnegara area and the analysis was carried out at the Pharmacy Laboratory of the Universitas Muhammadiyah Yogyakarta. The analytical method used was the identification of the hydroquinone content carried out by the TLC-densitometry method. Qualitative analysis used TLC, where the stationary phase used was silica GF254 while the mobile phase used was toluene - glacial acetic acid at a ratio of 8: 2. Samples were dotted using a microsyringe of 25 µL after extraction. Furthermore, the spot identification was carried out under 254 nm UV light and then the Rf value was calculated. Quantitative analysis was used. It was carried out by densitometry by looking at the area produced by the spots on TLC. In this analysis, the level calculation was carried out by comparing the area of the hydroquinone sample with the area of the positive control hydroquinone multiplied by the known hydroquinone level in the positive control. The results of the qualitative analysis showed that of the 21 samples, there were 6 samples or 28.57% of the samples containing hydroquinone. Quantitative analysis shows the levels in the six samples containing hydroquinone, namely sample no.11: 7,12%, sample no.12: 3.69%, sample no.15: 0.06%, sample no.16: 11.18%, sample no.18: 4.67%, and sample no.19: 1.07%. Based on the results of the analysis, several preparations contain hydroquinone exceeding a safe level of 5%, so it is necessary to regularly check testing and supervision from the authorized institution so that the circulating whitening cream is safe for use by the public.

Published: July 2021

It is an inevitable fact that the applications of machine learning and artificial intelligence technologies in agricultural biotechnology approaches, whose applications are increasing rapidly in almost every field, will have an important place in determining the future fate of agriculture. Applications in which artificial intelligence is adapted to biotechnological processes such as breeding, in vitro culture studies, germplasm preservation, disease-free plant production, genetic transformation, and other genetic analyzes are becoming increasingly common. In the current study is highlighted the potential benefits between artificial intelligence and agricultural technologies.  As with many plant species, viral diseases have negative effects on fruit yield, life span, and quality of olive varieties, which are important in economy. Elimination of viruses from the plant with traditional methods is quite laborious, takes a lot of time, and often fails to produce successful results. However, new protocols have been developed to eliminate persistent pathogens. These protocols include techniques such as heat application (thermotherapy), chemical therapy (chemotherapy), tissue culture methods (meristem culture). When these techniques are applied alone or together, it may be possible to obtain anti-virus plants.  Artificial intelligence technology will make it possible to benefit from the method to be used in the most efficient way by revealing which of these biotechnological methods can be used in the most effective and optimal conditions, and the possible advantages and disadvantages as a result of comparing with others.

Authors: Thang Nguyen Manh
Published: July 2021

This study examines the impact of using outsourced services on the performance of small and medium enterprises (SMEs) in Vietnam. The primary data used to analyze this study's main objectives were collected by the survey with the structured questionnaire and the expert interview with semi-structured interview guidelines. A total of 742 SMEs using outsourced services in the study area participated in the survey. The study employs Cronbach’s alpha test, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), structural equation modelling (SEM), and multiple-group analysis for variables measurements and model testing. The study also investigates the influences of the degree of outsourcing on the enterprise’s performance. The results show that the degree of outsourcing has a low impact on financial performance, particularly ROS, ROE, and ROA (R2 = 0.013). Also, the degree of outsourcing has impacts on non-financial performance. The multiple-group analysis results indicate the different influences of the outsourcing degree on the different types of enterprises’ performance. The degree of outsourcing has a stronger impact on micro-enterprises' performance than the small and medium-sized enterprises. The commercial and service enterprises have higher performance when outsourcing than others. The outsourcing degree has a stronger impact on the performance of the enterprises that operated for more than nine years than others. The results show that there are different influences of the outsourcing degree on the performance of the enterprises that have different outsourcing situations. According to the findings, this study proposes the three main managerial implications to improve outsourcing effectively, such as strengthening outsourcing risk management, deciding on outsourcing depend on the enterprises’ characteristics, and managing the relationship between stakeholders.
The Impact of Maternal, Perinatal, and Early Infancy Period on the Eruption Timing of the First Primary Tooth
Authors: Georgiadou Aikaterini I. , Ritsas Athanasios , Arhakis Aristidis
Published: July 2021

Aim: The aim of this study is to identify and review the literature on effect of perinatal and early infancy factors on the eruption chronology of the first deciduous tooth.

Materials and methods: A PubMed database literature survey regarding the influence of maternal, perinatal and early infancy period factors on eruption timing of the first primary tooth covering the period from January 1964 to 2020 was conducted.

Results: Maternal factors such as smoke exposure during pregnancy, gestational age or even Vitamin D levels could possibly affect the eruption timing. Strong association was evident between some perinatal factors like infant’s birth weight or ethnicity and primary teeth eruption chronology, as opposed to infant’s birth length or sex. Many studies indicated that prematurity could lead to delayed eruption timing, while other studies do not confirm that allegation. Additionally, weight gain during early infancy period seems to have a great effect on eruption timing, whereas feeding method’s impact is not clarified yet.

Conclusion: Eruption timing of the first primary tooth is not influenced by only one specific factor. Several conditions may act together and increase the risk of delayed or accelerated teeth eruption, occurring additively or even synergistically. The association between perinatal and early infancy factors and eruption timing of the first primary tooth needs further controlled studies as well as research in a wider spread of ethnicities.

Authors: Mohamadi-Shad Alireza , Niakan Hamed , Manzour Hasan
Published: July 2021

In this paper we proposed a new variable neighborhood search (VNS) for solving the location- routing problem with considering capacitated depots and vehicles. A set of capacitated vehicles, a set of depots with restricted capacities, and associated opening costs, and a set of customers with deterministic demands are given. The problem aims to determine the depots to be opened, fleet assignment to each depot, and the routes to be performed to satisfy the demand of the customers. The objective is to minimize the total costs of the open depots, the setup cost associated with the used vehicles, and transportation cost. We proposed a new VNS which is augmented with a probabilistic acceptance criterion as well as a set of efficient local searches. The computational results implemented on four well-known data sets demonstrate that the proposed algorithm is competitive with other well- known algorithms while reaching many best-known solutions and updating six best new results with reasonable computational time. Conclusions and future research avenues close the paper.

Published: July 2021

The wastewater treatment plant (WWTPD) located in Durrës, responsible for a treatment area of 205,000 inhabitants, employs the tertiary advanced wasterwater treatment to generate biogas from activated sludge for self use. The biogas collected from the anaerobic digestion tank feed the boiler and the co-generation unit which is then transformed to power its own energy grid. In order to evaluate the quality of biogas produced by anaerobic digestion of WWTPD’s sludge, is measured the percentage of CH4 and CO2 from the biogas production during a three years period (2016 – 2018).

From the performed analyses has resulted a percentage of CH4 up to 75% and 25% CO2 in 2016. While the lowest percentage of CH4 in 2018 with respectively 70% CH4 and 30% CO2.

Based on the value measurements, qualitative results of biogas parameters show that physicochemical and biochemical processes are performed under strict conditions and anaerobic digestion is performed according to standards.

Authors: Zakharov Igor , Botsiura Olesia , Semenikhin Valerii
Published: July 2021

Calibration of electrical resistance measures is considered by the indirect method, which is realized through measuring the voltage drop across the series-connected reference and calibrated resistors. The biases of the estimates of the measurand and the combined standard uncertainty due to the nonlinearity of the measurement model were calculated. The distribution laws of the input quantities in the calculation of the expanded uncertainty were taken into account by the kurtosis method. An example of measurement uncertainty evaluating during calibration of single-size electrical resistance measure R331 with a nominal resistance of 1000 Ω by comparing its value using a potentiometer R345 with the value of the calibrated reference standard is considered. Estimates of the measurand and its standard and expanded uncertainties obtained using the proposed method showed good agreement with the estimates obtained using the Monte Carlo method.
Reliable instrumental metering of natural gas is the key to Ukraine’s energy independence
Authors: Kovalenko Alina
Published: July 2021

By virtue of geographical and historic factors, Ukraine has been playing an important role in oil and natural gas deliveries to European energy markets. Such status is basically attributed to the fact that West and Central European countries, while being rather big consumers of natural hydrocarbons, have shortage in their own energy resources.

On the other hand, major natural gas and oil reserves are concentrated in the Russian Federation, Caspian region and the Gulf area. Currently Ukraine has become a major juncture in the transit of gas and oil from Russia and Kazakhstan to European markets. The expected increase in consumption of natural hydrocarbon resources, as well as their uneven distribution make Ukraine, owing to its suitable geographical location and the developed gas and oil network, an “energy bridge” between the exporting countries and consumers in the industrialized Europe.

In the article the author considers the modern gas supply system of Ukraine. The author carried out a study on the technical feasibility of calibration of flow meters on the environment of natural gas under pressure. Currently in Ukraine calibration is performed only in the air. This does not make it possible to reduce the error in the instrumentation of natural gas. Given the volume of natural gas consumption in the country (about 20 billion m3/year), this leads to huge non-production losses, negative impact on economic performance and inflated cost for end users. The European experience was analyzed: PTB, DNV, PIGSAR, SICK, INOTECH. Modernization of the gas industry of Ukraine is proposed.

Authors: Made Indira Dianti Sanjiwani  , I Made Widianantara
Published: July 2021

Uterine fibroids or leiomyomas are benign neoplasms that occur in the uterus and still become a health problem among women of reproductive age. Predominantly, uterine fibroids are found at productive age but some cases are found after menopause. Based on previous studies, there were 145 cases of uterine fibroids in 2014 and 69.7% were found in women over 40 years. Patients with uterine fibroids show a decreased quality of life with symptoms such as heavy uterine bleeding, pelvic pain, and loss of pregnancy. The pathogenesis of uterine fibroids is still unknown, but genetic factors, cytokines, growth factors, and steroid hormones are weak and play an important role in the development of uterine fibroids. Several studies have shown the effect of resveratrol that can be obtained from grape skins. Resveratrol can reduce extracellular matrix deposition and uterine fibroid cell proliferation. Looking at the induced events then resveratrol is effective in preventing the progression of uterine fibroids.

Authors: Mahardhika Gembong Satria
Published: July 2021

Abstract—COVID-19 is a major emerging disease that affects any certain condition. However, a recent report suggests the occurrence of hyperglycemia without any present diabetes in COVID-19 patients. This study aimed to systematically review recent evidence on hyperglycemia in COVID-19 patients. Literature research was done using four search engines, consist of Google Scholar, PubMed, ScienceDirect, and ProQuest, and limited to English manuscript only and published from February 2020 to September 2020. SARS-CoV-2 could damage the pancreas by causing the destruction of the β-cell structure that leads to impairment of glucose metabolism and worsen pre-existing diabetes or determine the appearance of hyperglycemia in non-diabetes. Inflammation also plays a major important role in hyperglycemia related to COVID-19.  Hyperglycemia increased the vulnerability of the lung, by promoting and facilitating the entry of the SARS-CoV-2 into the host cells, and decreasing lung function. Moreover, the mortality and morbidity rate conceivable increased due to hyperglycemia. The presence of high glucose levels is linked with the progression of COVID-19 severity. Thus, the glucose level should be concerned, either in a patient with present diabetes or without any presence of diabetes. Examination and monitoring of glucose levels might be a useful tool to prevent the seriousness of COVID-19

Authors: Fateye Tosin Babatola , Odunfa Victoria O. , Ibisola Abayomi S. , Ibuoye Ayodele A.
Published: July 2021

The study examined the community-based approach to finance basic public infrastructures in residential neighborhoods. The primary objectives of the study were to determine the condition of public infrastructures, the level of community engagement, the modalities of financing and the prominent influencing factors. The study adopted convenience sampling and questionnaire survey techniques. A total of 120 questionnaires were administered to residents of selected high-income communities (HICs) and low/medium-income communities (L/MICs), out of which 48 (80%) and 52 (86.67%) were retrieved, respectively, and analyzed. The study deployed descriptive statistics of mean and standard deviation models and mean weighted score to analyze the data. The study found that the residents were satisfied with the security of the neighborhoods but deplored the state of the public potable water infrastructure in both communities. However, the residents in the HICs enjoy a better condition of road infrastructure compared with L/MICs. The residents in both communities indicated a high level of involvement in the financing of public infrastructures, with major engagement in security and waste disposal/management infrastructures. However, the HICs engaged more in road grading/maintenance, while the provision of community potable water was given as a priority by the L/MICs. The major mode of financing basic communal infrastructures is through membership levy/contribution, and prominent influencing factors are cooperation among members, fundraising and income status. Therefore, while private-sector support funds, such as from the CDAs, help in cushioning the effects of basic infrastructure decay, governments at all levels should provide an enabling environment that will motivate mutual communal relationships through integrated infrastructure policies.

Flood risk analysis is the instrument by which floodplain and stormwater utility managers create strategic adaptation plans to reduce the likelihood of flood damages in their communities, but there is a need to develop a screening tool to analyze watersheds and identify areas that should be targeted and prioritized for mitigation measures. The authors developed a screening tool that combines readily available data on topography, groundwater, surface water, tidal information for coastal communities, soils, land use, and precipitation data. Using the outputs of the screening tool for various design storms, a means to identify and prioritize improvements to be funded with scarce capital funds was developed, which combines the likelihood of flooding from the screening tool with a consequence of flooding assessment based on land use and parcel size. This framework appears to be viable across cities that may be inundated with water due to sea-level rise, rainfall, runoff upstream, and other natural events. The framework was applied to two communities using the 1-day 100-year storm event: one in southeast Broward County with an existing capital plan and one inland community with no capital plan.

The discourse on the legality of alcohol in Indonesia has become a hot topic of controversy among various community. The supporters claim that the legality of alcohol is part of local wisdom so it deserves to be legalized. Meanwhile, the majority of Indonesian muslims have rejected this policy with various approaches. This turmoil is interesting to study in order to ground the Qur’an which has long forbidden khamar to be traded. This study used a phenomenological method which is based on the interpretation of the Qur'an, especially the thematic comparisons by the Tafsir Al-Maraghy, Al-Misbah, and Al-Qurthubi. There were three concluding phases of this study; First, the process of forbidding khamar in the Qur'an has certain phases and levels before it is totally prohibited. Second, the most dominant advantage of khamar is only in terms of trading, while the rest has more disadvantages. Third, khamr still applies to emergencies such as medical needs, alchemy, medicine and perfumes. In essence, the legality of alcohol which is to be consumed (drunkenness) is forbidden in Islam.
¿Una nueva forma de hacer política? Modos de gobernanza participativa y Ayuntamientos del cambio en España (2015-2019)
Authors: Mérida Juan , Tellería Imanol
Published: July 2021

Este artículo analiza las transformaciones en los modos de gobernanza a raíz de la implementación de nuevos mecanismos de participación introducidos por los “Ayuntamientos del Cambio” de cuatro ciudades españolas, Zaragoza, Valladolid, A Coruña y Pamplona durante el periodo 2015-2019. En un contexto de urbanismo de austeridad (Peck, 2012), y desde el Enfoque Estratégico Relacional (EER) (Jessop, 2017) que entiende el Estado como una relación social, la investigación analiza a partir de un marco operativo innovador de qué manera las políticas participativas introducidas por dichos ayuntamientos modifican la selectividad estratégica heredada. Es decir, si se establece una nueva red de políticas públicas (policy network) más inclusiva y participativa. Demostramos como la  apuesta municipalista supone una ruptura con la etapa neoliberal de austeridad generada entre 2003-2007 en España, la cual habría erosionado las prácticas y culturas participativas que afloraron en la década de los noventa y comienzos de los dos mil (Davies y Blanco, 2017).

Bradycardia during the early period following heart transplantation frequently occurs with an incidence of 14 to 44% and it is usually self-limited. The incidence of late bradycardia (from 30 days to more than 5 or 6 months after transplantation) has been reported to be 1.5%. A 33-year-old male patient with a history of orthotopic heart transplantation in 2013 presented with complaints of dizziness and near syncope. A DDDR permanent pacemaker was implanted for sinus pauses exceeding 3 seconds recorded on Holter examination. Shortly after the procedure, he developed sudden cardiovascular collapse. Cardiopulmonary resuscitation was performed and a pulse steroid treatment (2 grams of methylprednisolone) was given. After 2 days, the patient was extubated. While making preparations for re-transplantation, cardiopulmonary arrest developed again and he died. Sinus pause may be a clue for rejection and is an important finding in predicting clinical course.

Published: July 2021

The influence of anodization time with the electrochemical cell design on the fabrication process of porous silicon (PS) nanostructures based on two electrochemical anodization cells (designed single tank cell and double tank cell) with two anodization times (10 and 30 minutes) was studied. Atomic force Microscopy (AFM) characterization had revealed three types of pores, mesopores, mesopore fill of mesopores, and macropore fill of mesopores were obtained from designed single tank cell with (10 and 30 minutes) of anodization time, whilst for double tank cell has not revealed precise information about the size and type of pores. Pores formation have been further approved by current-voltage (I-V) measurement and photoluminescence emission by ultraviolet-lamp (254-366) nm for both electrochemical cells.

3D geological model for each reservoir unit comprising the Yamama Formation revealed to that the formation is composed of alternating reservoirs and barriers. In Subba and Luhais fields the formation began with barrier YB-1 and four more barriers (YB-2, YB-3, YB-4, YB-5), separated five reservoirs (YR-A, YR-B, YR-C, YR-D, YR-E) ranging in thickness from 70 to 80 m for each of them deposited by five sedimentary cycles. In the Ratawi field the formation was divided into three reservoir units (YR-A, YR-B, and YR-C) separated by two barrier units (YB-2 and YB-3), the first cycle is missing in Ratawi field.  

The study involves 1 well in Luhais field (Lu-12), 3 wells in Subba field (Su-7, Su-8, and Su-9), and 5 wells in Ratawi field (Rt-3, Rt-4, Rt-5, Rt-6 and Rt-7), the Luhais, Subba, and Ratawi fields located in the Mesopotamia zone (Zubair subzone).

The reservoir units (YR-C and YR-D) in Subba oil field, and YR-B in Ratawi oil field represent the major reservoir units that characterized by the best Petrophysical properties (the highest porosity, the lowest water saturation, and the best Net Pay Thickness), Luhais oil field has poor to moderate Petrophysical properties and low oil bearing in YR-A, YR-B and YR-C units, and produce heavy oil and salt water from YR-D and YR-E as indicated by low resistivity log reading, and according to the Drill Steam Test (DST) with the description of cutting in final geological reports.

Heavy metals concentration in the soils and sediments has increased worldwide during the last century as a result of the rapid increase in population which combined by an increase in human activity as agriculture,  industrial and many other activities. Ten soil and three river sediment samples were collected from 10 main sampling stations at Shatt Al-Hilla River from Sada area to Dora Bridge in Babylon province. The chemical analysis of the sedimentation sample in the laboratory included pH calculation, electrical conductivity (EC) (Cation Exchange Capacity (CEC), organic matter (OM), and heavy metals as (Mn, Ni, Cr, Zn, Cu, Co, Pb, Cd, As and Fe). Indirect geochemical background (IGB) of heavy metal was calculated by the iterative 2 standard deviations (SD) method.

The results of enrichment factor for heavy metals of the soil and sediment show that the all heavy metals in the studied samples were within Ef<2 indicate to depletion to minimal enrichment (i.e. no or minimal pollution). While Cd in the sample (5), Co in the sample (7), Cr in the sample (8) and Mn in the sample (1S) are within 2 â‰¤ EF < 5 indicate to Moderate enrichment. Contamination factor (Cf) for heavy metals of soil and sediment show that the all heavy metals in the studied samples were within Cf < 1 -Low contamination. While Sample "2" (Cd, Fe), sample "3" (Ni, Cr, Pb, and Cd), sample "4" (Mn, Fe) and sample "8" (Cr) are within 1 â‰¤ Cf < 3 moderate contamination.

Pollution load index result of all the soil and sediment samples are less than one indicate that  "no pollution" are present, except sample 3 where the PLI value higher than 1 indicates the samples have been "polluted ". The modified degree of contamination (mCd) data indicate nil to a low degree of contamination for all of the soil and sediments samples.
