Abstract
The photocatalytic degradation and mineralization of Reactive Orange 30 on NiO/CuO/TiO2 ternary composites have been studied using solar light irradiation. The NiO/CuO/TiO2 ternary composites were prepared by producing ethanolic dispersions containing varied amounts of NiO and CuO/TiO2 (3wt% to 15wt.%), followed by annealing at 300 °C. SEM, UV- Vis DRS, PL, XRD and FTIR analysis have been used to characterize the unary (parent photocatalysts), binary and ternary composites. Under solar light irradiation, NiO/CuO/TiO2 ternary composites exhibited an excellent photocatalytic activity in degradation of reactive orange 30 in aqueous solution, whereas the NiO/TiO2, CuO/TiO2 and bare photocatalyst such as NiO, CuO, TiO2 showed lower activities. It was deduced that the remarkable visible-light absorption phenomenon and band gap reduction of the NiO/CuO/TiO2 ternary composites taking place. It paves way for the photogenerated electron transfer between CB of the NiO, CuO, TiO2 semiconductors and also holes shifting between VB of above mentioned materials. The NiO/CuO/TiO2 ternary composite shows good photostability and the photocatalyst retains 94% of its initial activity in the seventh cycle, respectively.

Abstract

Introduction: This study attempts to assess the concentration of intracellular matrix metalloproteinase (MMP-9) before and after the treatment of depressive episodes with ECT therapy and also to correlate the concentration of this enzyme with the use of commonly used general anaesthetics.

Materials and methods: The study group comprised of 37 patients hospitalized in the Department of Adult Psychiatry in Poznan, with a diagnosis of episodes of drug-resistant depression during the course of bipolar and unipolar affective disorders, and who were being treated using electroconvulsive therapy. For the purpose of inducing anaesthesia during the procedure propofol was used in 10 cases, thiopental in 9 cases. Propofol was alternated with ketamine in a further 10 cases and thiopental was alternated with ketamine in another 9 cases. In order to assess the intensity of depression symptoms, the 17 point Hamilton depression scale was used, immediately before commencing ECT therapy, and one day after its completion. The serum concentration of MMP-9 was determined before and after the series of ECT treatments. In order to assess the serum concentration of MMP-9, an ELISA immunoenzymatic method was applied.

Results: In this study, a significant reduction of MMP-9 concentration was noted after therapy, relative to the starting concentration, in the serum of patients suffering from depressive episodes resulting from either unipolar or bipolar affective disorders. These results correlated with improved psychiatric state, as assessed by the Hamilton scale. A significantly lower MMP-9 concentration was noted in the serum of patients given alternating thiopental and ketamine anaesthesia.

Conclusions: This study suggests the importance of the enzyme as a biological marker for the effective treatment of depression. Furthermore, the choice of general anaesthetic applied during ECT also plays a role.
Use of a Carbon Dioxide Measurement System to Control the Process of Obtaining Breathing Air for Hyperbaric Oxygen Conditions
Authors: Woźniak Arkadiusz 
Published: April 2022

Abstract
Maintaining a stable carbon dioxide content in the process of producing breathing air is important both for the safety of divers performing underwater work and for avoiding financial losses resulting from poor product quality. This paper deals with the implementation of safety measurement systems for online control of the breathing air production process. On the basis of a qualified control system, the capability of the rationalised process was assessed, identifying both its current status and its potential for improvement in terms of eliminating defects caused by excessive carbon dioxide content. For process reasons, the effectiveness of online process monitoring was evaluated against the previously used periodic sample control by means of laboratory methods of instrumental analysis. The analysis was conducted at KTPP AMW1 for the compressed air supply system of the DGKN - 1202 complex.

Abstract
The impact of the Coronavirus disease 2019 (COVID-19) pandemic varies as each country has a different capacity to stop the virus transmission and apply social distancing. A densely populated country, such as Indonesia, tends to face challenges in implementing social distancing due to population characteristics. The Indonesian government focuses on the medical aspect as this virus is new and has been deadly with a high transmission rate. Meanwhile, the non-medical risk during the pandemic is still unclear. The main objective of this study is to assess the non-medical risk at the village level in two agglomeration cities of Central Java: Greater Surakarta and Surabaya. The methodologies use a risk index, derived from the risk reduction concept. The hazard refers to the death toll, while the vulnerability relates to parameters such as disaster, social and public facilities, health facilities, economics and demography. Further, the parameters were weighted based on expert judgement derived using analytical hierarchy process (AHP). The study found that the disaster aspect had the highest weight (0.38), followed by health facilities (0.31), economics (0.17), social-public facilities (0.11) and demography (0.04). The standard deviations of those parameters were relatively low, between 0.12 and 0.25. A low vulnerability index (0.05–0.36) was observed to be dominant in both study areas. There are 11 villages in Greater Surakarta and 30 villages in Greater Surabaya with high vulnerability index. Disaster-prone areas, low economic growth, lack of health facilities and aged demographic structure significantly added to this vulnerability. Further, a high-risk index (0.67–1.00) is observed in three villages in Greater Surabaya and one village in Greater Surakarta. These villages are relatively close to the city centre and have good accessibility. Furthermore, these four villages experienced the severest impact of the pandemic because the furniture and tourism sectors were their primary industries.

On Liberty and Cruelty: A Reply to Walter Block
Authors: Huemer Michael 
Published: April 2022

Abstract
A standard argument for ethical vegetarianism contends that factory farming – the source of nearly all animal products – is morally wrong due to its extreme cruelty, and that it is wrong to buy products produced in an extremely immoral manner. This article defends this argument against objections based on appeal to libertarian political philosophy, the supposed benefit to animals of being raised for food, and nonhuman animals’ supposed lack of rights.

Published: April 2022

Abstract
Multiple sclerosis is a chronic inflammatory demyelinating disease of the central nervous system characterized by multiple disseminated lesions. The pathogenesis of this disease is still insufficiently clarified, and the course of the disease is unpredictable. It happens that severe relapses do not respond to drug therapy and in such cases it is recommended therapeutic plasma exchange (TPE).
We present a young man with severe motor relapse, weakness of the left leg, pronounced tremor of the right arm, unstable gait and bilaterally reduction of vision. Brain magnetic resonance imaging showed a large number of chronic demyelinating lesions of the white mass, numerous were merged, with signs of brain reduction. The patient underwent five cycles of TPE, which were conducted every other day. Although TPE led to a disturbance of the hemostasis status and some biochemical parameters, the patient’s response to the applied therapy was good. The improvement of the patient’s condition was reflected through the return of vision and a moderate reduction in neurological deficit.
Despite the fact that therapeutic plasma exchange can cause some complications, it should be considered when drug therapy does not lead to improvement in these patients.

Cytotoxic effects of CeO2 NPs and β-Carotene and their ability to induce apoptosis in human breast normal and cancer cell lines
Authors: Al-Ali Ali A.A. , Alsalami Khalid A. S. , Athbi Ahmed Muhssin 
Published: April 2022

Cerium Oxide Nanoparticles (CeO2 NPs) and β-carotene are natural-source products that have recently gained an increased interest as pharmaceutical additives because of their effectiveness in living systems, but the behavior of these substances varies according to factors and conditions. The above mentioned materials were evaluated in breast normal (HBL-100) and cancer cell lines (CAL-51 and MCF-7 ) by different techniques ; MTT assay for studying cytotoxic effects, morphological changes, sqPCR, including gene expression of caspases 8 and 9, and P53. All experiments were conducted on cell lines by the use of the materials alone as well as their combination.
The results of the MTT assay showed that the two materials (CeO2 NPs and β-carotene) had a toxic effect on the cell lines, and the toxicity of the materials was concentration-dependent. The half maximal inhibitory concentration (IC50) values of CeO2 NPs and β-Carotene, as observed by the effects in all cell lines, have significant differences.
Our findings showed that CeO2 NPs has a higher toxicity on the HBL-100 and MCF-7 cell lines compared with β-Carotene. The toxic effects of each material alone and combined together were reflected on cell morphology by the appearance of irreversible cytopathic changes in the treated cells. The two materials had the ability to cause cellular death and DNA damage, inducing the external pathway of apoptosis. A significant increase in the gene expression of caspase 8 appeared at P≤0.05. Collectively, the CeO2 NPs and β-Carotene have an inhibitory effect on both breast cancer and normal cell lines. We conclude the both materials have genotoxic effects on normal and cancer cell lines.
Mean Latin Hypercube Runge-Kutta Method to Solve the Influenza Model
Authors: Mohammed Shatha Jabbar , Mohammed Maha A. 
Published: April 2022

In this study, we propose a suitable solution for a non-linear system of ordinary differential equations (ODE) of the first order with the initial value problems (IVP) that contains multi variables and multi-parameters with missing real data. To solve the mentioned system, a new modified numerical simulation method is created for the first time which is called Mean Latin Hypercube Runge-Kutta (MLHRK). This method can be obtained by combining the Runge-Kutta (RK) method with the statistical simulation procedure which is the Latin Hypercube Sampling (LHS) method. The present work is applied to the influenza epidemic model in Australia in 1919 for a previous study. The comparison between the numerical and numerical simulation results is done, discussed and tabulated. The behavior of subpopulations is shown graphically. MLHRK method can reduce the number of numerical iterations of RK, and the number of LHS simulations, thus it saves time, effort, and cost. As well as it is a faster simulation over the distribution of the LHS. The MLHRK method has been proven to be effective, reliable, and convergent to solve a wide range of linear and nonlinear problems. The proposed method can predict the future behavior of the population under study in analyzing the behavior of some epidemiological models.

Published: April 2022

Mixed spinel Mg1-xZnxFe2O4 ferrites (where x = 0, 0.2, 0.4, and 0.6) nanoparticles were synthesized by using microwave-assisted combustion route. As-synthesized powdered samples were checked by XRD analysis, field emission-scanning electron microscopy, and vibration sample magnetometer to investigate the structural, morphology, and magnetic properties, respectively. XRD results exhibited that the crystallite size increases with the decrease of Zn+2 ion concentration for series of mixed spinel Mg1-xZnxFe2O4 ferrite expect x=0.2. All the mixed spinel Mg1-xZnxFe2O4 ferrite has different grain sizes with uniform distribution also presence voids in the samples. Pure magnesium ferrite has a lower net magnetization value but when magnesium ions (Mg+2) are replaced by zinc ions (Zn+2) then the value of saturation magnetization increases.
