Published: September 2022

Cases of bullying in schools are still a major problem in many countries and must be resolved immediately because they are closely related to student morale. So far, schools are still focused on strategies to overcome bullying, but have not focused on exploring the right measurement model to identify bullying. This study aims to identify bullying systematically in schools. This is a quantitative research using principal component analysis (PCA). The questionnaire was developed based on the findings of previous studies. Internal factors and consistency were examined by involving 96 students from senior high schools in Indonesia. This study concludes that the model for measuring bullying in schools is measured by four indicators, namely setting, bullies, reasons for bullying and forms of bullying. This measurement model is measured by a total of 21 items that have been tested through PCA.

Keywords: PCA, bullying measurement, schools.

<p>An aerator is a device that utilized to produce dissolved oxygen in water through a diffusion process. Generally, the aerators employed by farmers are operated manually by an operator. The design and utilization of a smart device such as the Zelio Smart Relay is one of the objectives of this article. With the use of smart relays, it is expected that the presence of operator can be eliminated and able to reduce operational cost. The type of aerator discussed in this article is a dual turbine aerator. Each turbine has 6 blades. In order to have the smart relay to operate properly, at least 2 (two) sensors are needed as inputs, namely the light intensity and the temperature sensor. Furthermore, dissolved oxygen levels in water are categorized as high (30 mg / L) if the light intensity is higher than 100,000 lux and the temperature lower than 35<sup>0</sup> C. It shows in the results that the implementation of aerator has the capabilty to increase dissolved oxygen from 8 mg / L - 14.4 mg / L in 45 minutes, therefore the quantity and the quality of dissolved oxygen required by shrimp farming can be fulfilled properly.</p><p><em><br /></em></p><p><strong>BAHASA INDONESIA ABSTRACT</strong><em><strong>: </strong></em><em>Aerator</em> adalah salah satu alat bantu yang berfungsi untuk memproduksi oksigen terlarut dalam air melalui proses difusi. Sampai saat ini, aerator yang dimanfaatkan oleh para petani pada umumnya masih bersifat manual dengan cara dioperasikan dan dikendalikan oleh tanaga operator (manusia). Perancangan dan pemanfaatan teknologi cerdas seperti <em>Zelio Smart Relay</em> merupakan salah satu bahasan pada artikel ini. Dengan adanya pemanfaatan <em>smart relay</em> tersebut diharapkan pekerjaan operator pada pertanian tambak udang dapat dipermudah dan mampu menekan biaya operasional. Jenis aerator yang dibahas pada artikel ini adalah aerator turbine ganda yang memiliki 6 buah sudu di tiap tiap kincirnya. Agar sistem kendali yang dirancang pada smart relay beroperasi dengan baik, maka diperlukan sedikitnya 2 (dua) buah sensor yaitu sensor intensitas cahaya dan sensor suhu yang terukur pada kolam (air). Selanjutnya kadar oksigen terlarut dalam air dikategorikan tinggi (30 mg/L) apabila intensitas cahaya &gt; 100.000 lux dan untuk suhu &lt; 35<sup>0</sup> C. Dari hasil penerapan aerator di kolam dapat diketahui bahwa aerator dengan penambahan <em>Zelio Smart Relay </em>ini dapat bekerja sesuai dengan perancangan, yaitu dapat meningkatkan oksigen terlarut dari 8 mg/L – 14.4 mg/L dalam 45 menit, dengan demikian kuantitas oksigen terlarut yang dibutuhkan oleh pertanian udang dapat dipenuhi dengan baik.</p><p> </p>

Published: September 2022

Background: Carbamazepine is an antiepileptic drug used to treat trigeminal neuralgia and pain associated with neurological disorders. The drug belongs to class II of the Biopharmaceutical Classification System (BCS), which has low solubility. Hence, dissolution is a rate-limiting step. Objective: This study aimed to determine the best formula for carbamazepine nanoparticles based on physical characteristics and determine the effect of chitosan and Na-TPP concentration variation on nanoparticle characterization. Methods: The carbamazepine chitosan nanoparticles were prepared using ionic gelation method with a concentration of 0.1% w/v carbamazepine and the ratio of chitosan and Na-TPP concentrations of 0.2%:0.1% (F1), 0.2%:0.2% (F2), and 0.3%:0.1% w/v (F3). The parameters evaluated included particle size, polydispersity index, zeta potential, particle morphology, and entrapment efficiency. Statistical analysis was conducted on the evaluation data using One Way ANOVA. Results: The results showed that the effect of increasing the concentration of chitosan reduced particle size (p<0.05), increased zeta potential (p<0.05), and had no effect on the value of entrapment efficiency (p>0.05). Furthermore, F3 had a particle size of 169.8±13.71 nm with a polydispersity index of 0.378±0.02, the zeta potential of +28.80±2.44 mV, entrapment efficiency of 84.3±7.50%, and spheric particle morphology which was measured using Transmission Electron Microscope (TEM). Conclusion: Therefore, F3 with the ratio of chitosan and Na-TPP concentrations of 0.3%:0.1% was the formula that provided the best characteristics of chitosan carbamazepine nanoparticles.

Published: September 2022

Introduction. Birth weight is one of the most important factors determining neonatal well-being. From an epidemiological viewpoint, a neonatal reference chart provides a picture of the health status of a population. Global customized growth charts seem to be the most practical in multicultural settings, allowing adjustment for ethnicity. However, regional charts might be a valuable contribution to reliable growth assessment. Our study aims to establish a reference tool for growth assessment and visualize the local potential, by creating standard charts based on the data from the tertiary center with the highest number of deliveries per year in Poland.
Material and Methods. We retrospectively analysed 31,353 records from the electronic database of singleton births from a five-year period from a tertiary hospital in Poznań, Poland. We excluded pre-term deliveries and high-risk pregnancies basing on well-known factors influencing fetal growth, bringing the number of records to 21,379. The data were processed separately by gender (females n=10,312, 48.2% and males n=11,067, 51.8%). Percentiles were calculated for each week of gestational age. Means and standard deviations were determined.
Results. Standard growth charts (including 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentiles) are presented. Descriptive data of population distribution are shown.
Conclusions. In conclusion, obtaining standard growth charts for mature newborns has created the opportunity for a more actual and adequate assessment of the Polish neonatal population. It should allow for the implementation of new standards in future research on perinatal care.

Authors: Kekana Tebogo Johannes , Montle Malesela Edward 
Published: September 2022

The objects of this research are, First, to highlight the unfair language practice that is still persisting in the South African Judicial System despite the provisions contained in the democratic constitution of equitable use of all official languages. Second, to explore the variables that contribute to this appalling state of affairs where English is predominately used in the South African Judicial System. Third, to suggest possible measures that could be applied to lessen or circumvent the situation.
The researcher investigated the following problem, The inadequate use of the official indigenous languages in the South African Judicial System, the reasons behind this practice and its consequences.
The main results of the research are, first, English is still the predominately used language in the South African courts of law and minimal use of official indigenous languages in the judicial system is still continuing unabated. Second, language policy regarding the South African Judicial System need to be reviewed with the aim of putting emphasis on the use of official indigenous languages for various activities in the judicial system, secondly, benefits derived from adequate use of official indigenous languages in the judicial system need to be explored more so that maximal participation of people who speak these languages can be achieved. Third, the study has shown that the reason for this inadequate use of the official indigenous languages is as a result of various intertwined variables such as globalisation, economic factors, negative attitudes towards African languages and a lack of existing inclusive language policies regarding the SA judicial system. Fourth, the use English language for various purposes in the judicial system is a linguistic injustice, it portrays the South African judicial system as still not transformed but still colonised.
The area of practical use of the research results are, all citizens who seek justice through South African judicial System, Law practitioners in South Africa, human rights organisations, university students and staff members of the criminal justice department.

Authors: Keci Erjola , Pepa Bledar , Paparisto Anila , Lazo Pranvera 
Published: September 2022

Abstract
Compliance with the Water Framework Directive has not yet been met by Albania, and further efforts are needed to achieve this goal, including the implementation of an extensive programme of monitoring of surface and groundwater bodies. Benthic macroinvertebrates are an integrated element of this monitoring programme whose results are being used to assess the achievement of the Water Framework Directive objectives. This study has been carried out strictly following protocols and methodologies of the Water Framework Directive. The biological assessment took place in 2017 at 11 monitoring stations along the Drin River in Albania. Sampled specimens have been used to assess the water quality along the Drin River Basin through a set of indices’ calculations per each group of indicators. A total of 41 benthic invertebrate taxa were used to calculate the biotic indices, finding out only 3 monitoring stations with a good status of water out of 11 monitoring stations assessed in our study; water quality in 8 monitoring stations is classified as a moderate or poor status. Statistical analysis has been carried out to identify the trend of benthic invertebrates from one sampling point to another and the factors influencing the similarity between monitoring stations and benthic invertebrate families.
The influence of projection angle on nappe stability at low energy heads over the weir crest
Authors: Khodier Mohanad A. , Tullis Blake P. 
Published: September 2022

Abstract
Under certain low head hydraulic conditions, weir discharge under gravity flow can produce an oscillating nappe characterized by horizontal waves and audible low-frequency acoustic energy, which in some cases can have a significant impact on the local environment. In an effort to better understand the mechanism behind nappe oscillation, an experimental investigation was conducted using a linear weir (1.83 m wide, 1.10 m in height, and 0.076 m in thickness) with four different crest shapes (rectangular, quarter-round upstream, half-round, and quarter-round downstream) at a wide range of unit discharge ranging from 8×10−3 m2/s to 36×10−3 m2/s. Using Particle Image Velocimetry (PIV) techniques, differential pressure measurements, and water surface profiles, the influence of Weber number, angle at which the nappe hits the downstream pool (angle of impact), and nappe projection angle on the nappe oscillation are reported. No significant relationship was found between the Weber number and nappe instability. The results suggest that the nappe is stable for unit discharge between 20×10−3 and 24×10−3m2/s regardless the shape of the weir crest. Also, the stable projection angle is −17° for rectangular and quarter-round upstream weirs and −35° for half-round and quarter-round downstream weirs for the specific tested weir.

Abstract
Contamination of water resources with various pollutants and therefore lack of clean water resources are major problems that threaten many human societies. The need to develop efficient methods and materials to decontaminate water resource is an undeniable fact. Metal-organic frameworks (MOFs), as new class of highly crystalline porous solids, have attracted a great deal of attention in different research fields, especially in adsorptive removal and purification. In this study, MIL 101(Cr) MOF decorated with graphene oxide nano-layers (GO/MOF) was synthesized by a simple one-pot hydrothermal method. Scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and electron dispersion energy (EDS) were utilized to approve the growing of Cr-MOF on graphene oxide nano-layer. The synthesized nano-composite was used as a potential adsorbent for the removal of a pesticide, 2, 4-dichlorophenoxyacetic acid (2,4 D). The adsorption performance, kinetic and mechanism of 2,4 D adsorption onto GO/MOF were studied. The highest adsorption capacities of 476.9 mg g−1 was obtained at room temperature, pH 6.0 using 0.6 gL−1 of GO/MOF which was 34% higher than that of pristine Cr-MOF. The kinetics and isotherm data fitted well with pseudo-second kinetic and Langmuir isotherm model, respectively. The reusability and stability analyses showed that the synthesized GO/MOF nanocomposite kept 89% of sorption capacities for 2,4 D after four adsorption–desorption cycles. GO/MOF nano-composite was successfully applied to remove 2,4 D from agricultural waste. The results approved that the synthesized nano-composite could introduce as a stable and high performance adsorbent for adsorptive removal of selected pesticide.

Authors: Ayoub Mohamed 
Published: September 2022

AbstractThe present study intends to investigate the performance of the Fenton reaction as one of the most efficient (AOPs) in a batch mode for treating wastewater effluent from the edible oil industry, as well as the parameters that influence the reaction, such as pH, hydrogen peroxide (H2O2), and ferrous sulfate heptahydrate (FeSO4.7H2O) doses at various reaction times. The response surface methodology (RSM) was applied with a central composite design (CCD) for optimizing the responses of pollutant removals. The obtained results indicated that the authenticated response to the chemical oxygen demand (COD) removal was 93.52%, at optimum values of pH, FeSO4.7H2O dose, H2O2 dose, and reaction time of 3, 1 g/L, 8.38 g/L, and 50 min, respectively. Furthermore, the authenticated response to oil and grease (O&G) removal was 99.8%, at optimum values of pH, FeSO4.7H2O dose, H2O2 dose, and reaction time of 3, 0.71 g/L, 8.7 g/L, and 37.4 min, respectively. Under these conditions, the residual COD and O&G after Fenton oxidation become 155.4 mg/L and 10 mg/L, respectively.
