Authors: Zaki M,
Published: July 2022

This paper discusses the concept of caliphate which is one of the substances of Islamic education learning in Islamic School, and the development of its paradigm toward a form of contextualization of the vision, mission and strategy of national education development. This study focuses on several changes in the content of the Islamic Education Studies and Arabic Studies which included in KMA 183 in 2019, the lesson of caliphate has been moved from the Fiqh subject to Islamic Cultural History. This study uses an interpretive descriptive approach, which is a method and approach in the study of beliefs, ideas and discourses that are developing around the  KMA 183 policy. This study produces a conclusion about policy-making from various aspects, one of them is an effort to contextualize the Islamic Education Studies. and Arabic Studies in order to be “in tuned” with the vision and mission of the national education strategy. The author concludes that the reconstruction of khilafah’s term from the context of Islamic law to Islamic civilization actually builds a new wave of Islamic political treasures which not only touch the cognitive area, but also become a reflection as well as actualization in the dimensions of social life.

Penulisan ini bertujuan untuk mengetahui bagaimana pemikiran politik islam Al-Maududi dalam dinamika politik kontemporer serta mengetahui bagaimana konsep pemikiran politik Islam Al-Maududi. Dalam penelitian ini, penulis menggunakan metode penelitian deskriptif kualitatif yang menjelaskan fakta-fakta dengan memanfaatkan data sekunder, yakni data yang diperoleh dari jurnal, artikel, dan website. Al-Maududi adalah salah satu pemikir muslim yang berasal dari Pakistan. Sejak berusia muda, Al-Maududi sangat tertarik dengan persoalan politik di negaranya. Dikarenakan situasi dan suhu politik yang sedang terjadi di negerinya, secara langsung atau tidak langsung mempengaruhi dan mencuri perhatiannya. Maka dari itu, muncullah pemikiran politik Islam Al-Maududi. Pemikiran politik Al- Maududi mencita-citakan terwujudnya negara Islam yang berdasarkan pada Al-Qur’an dan Hadist. Oleh karena itu, ia merumuskan sebuah kerangka aturan tentang negara Islam tersebut. Ia tidak dapat menerima bentuk serta model negara lainnya. Namun yang terpenting menurutnya ialah kedaulatan yang dianut adalah kedaulatan Tuhan (Theo-Demochracy) sebagai ciri negara Islam. Tidak seperti model negara Republik pada umumnya yang memakai system kedaulatan rakyat atau demokrasi.

The problem on food health is the high amount of bacterial contamination of food served by food industries. The quality of beef can be affected by the level of bacterial contamination in meat. Coliform is a group of bacteria used as a sanitary hygiene indicator. The purpose of this study is to measure the value of MPN Coliform in beef at Krian’s abattoir of district Sidoarjo. Thirty samples were taken from the abattoir of Krian, Sidoarjo. Most Probable Number was used to determine the level of Coliform's contaminate beef. The results showed that all beef samples at abattoir were contaminated with Coliform. The average contaminant levels was 706,76 MPN/g. Twenty six samples exceed the maximum limit of Coliform bacteria contamination in accordance with Indonesian National Standard (SNI). The highest Coliform MPN value is ≥ 1600 MPN / g, whereas the lowest MPN Coliform value is 8 MPN/g.
NON-MUSLIM PERCEPTION OF ISLAMIC BANK: IS RELIGIOSITY MORE IMPORTANT THAN LOCATION, PROMOTION, & PRODUCTS
Authors: Hadziq M. Fuad , Ismiyanti Nina
Published: July 2022

From a societal perspective, religion is one variable that contributes to economic growth. Islamic banks' brand image remained limited to Muslims, not to other consumers worldwide. Therefore, the point of this study is to examine the impact of religiosity on non-Muslims' perceptions of Islamic banks when compared to internal characteristics such as location, advertising, and product. This research applies a quantitative approach, analyzing numerical data from non-Muslim community demographic descriptions. The causal and contributory relationships between variables are estimated. This research employed a route analysis approach—a questionnaire with a Likert scale was utilized in conjunction with in-depth interviews. The sample was selected from Palangka Raya, Central Kalimantan, a multi-ethnic, multi-cultural, and primarily multi-religious city with 370 non-Muslims. The analysis method used path analysis that helped by SPSS 17.0. The sample was selected using a mix of area sampling and convenience sampling. The findings indicated that religion had little influence and made a negligible contribution to non-Muslims' perceptions of Islamic banking. The marketing mix elements of location, promotion, and product have a more significant effect on how Islamic banks are perceived. Islamic banks are not widely perceived as being exclusively for Muslims. Religious considerations are not the primary element in choosing a bank. Non-Muslims are typical sensible buyers.

Authors: Jamil Mohd Atif , Khanam Sidra
Published: July 2022

Rolling element bearings are crucial components of rotating machinery used in various industries, including aerospace, navigation, machine tools, etc. Therefore, it is essential to establish suitable techniques for condition monitoring and fault diagnosis of bearings to avoid breakdowns and damages during operation for overall industrial sustainability. Vibration-based condition monitoring has been the most employed technique in this perspective. Many researchers have investigated the vibration response of rolling element bearings having inner race defects, outer race defects, or rolling element defects using conventional techniques in past decades. However, Machine Learning (ML) has emerged as another way of bearing fault diagnosis. In this work, fault signatures of ball bearings are classified using a total of 6 (with 24 subcategories) ML models, and a comparative performance of these models is presented. The ML classifiers are trained with extracted time-domain and frequency-domain features using open-source Case Western Reserve University (CWRU) bearing data. Two datasets of different sample size and number of samples of vibration data corresponding to a healthy ball bearing, a defective bearing with inner race defect, a ball defect, and an outer race defect, running at a particular set of working conditions, are considered. The accuracy of ML models is compared to identify the best model for classifying the faults under consideration.

The Association of Partner Type Instability with Sexual Orientation Incongruity among Sexual Minorities in Britain: Findings from the National Survey of Sexual Attitudes and Lifestyle 2010-2012
Authors: Sullins D. Paul , James Steph
Published: July 2022

Background: Previous study of sexual minorities has documented both instability in the sex of sex partners and incongruity among all three dimensions of sexual orientation (attraction, behavior and identification), but no attempt has been made to relate the two. How, if at all, does past change affect present incongruity? This study attempts, for the first time, to examine this question. Method: Using a representative probability sample of the British population (n = 15,162), the current dimensions of sexual orientation were compared across changes in sex partner type—opposite-sex only (O/Sex), same-sex only (S/Sex), or both opposite-sex and same-sex (B/Sex)— over three time periods—before 5 years ago (Time 1), 5 years to 1 year ago (Time 2), and the past year (Time 3)—for the nonheterosexual population. Differences and trends in population-weighted percentage frequencies stratified by sex were assessed by t-test or inspection of 95% confidence intervals. Results: Overall incongruity and instability were high: 74% of men and 85% of women did not report congruent lifetime sexual attraction, behavior and identification; of persons reporting any same-sex sex partners at Time 1, 82% reported a different partner type at Time 3. Most change (80% for women, 84% for men) involved a single partner type transition (transience) rather than multiple changes (fluidity) and movement toward increased heterosexual orientation (69%; 65% to O/Sex partners. From Time 1 to Time 3, 19% of persons with S/Sex partners moved to O/Sex partners; 0.1% of persons with O/Sex partners moved to S/Sex partners. Instability moderately reduced already high incongruity for the majority moving toward increased heterosexual orientation, but increased already low incongruity for the minority moving toward increased same-sex orientation. Among presently S/Sex partnered persons (comprising 12% of sexual minorities), incongruity was reported by 1.4% of persons with stable partnership history and 11% of persons with unstable partnership history (p=.0052). For all except presently S/Sex partnered persons (comprising 88% of sexual minorities), incongruity was reported by 97% of persons with stable partnership history and 86% of persons with unstable partnership history (p=.0000). Conclusion: For most sexual minority persons, partner type instability contributed to a modest reduction of high sexual minority orientation incongruity after moving toward increased heterosexual practice. Among current S/Sex partnered persons, however, instability strongly increased incongruity between identification and behavior or attraction. These results are consistent with minority stress theory but inconsistent with homosexual immutability, and counsel caution regarding legal restrictions on support for sexual minority persons moving toward increased heterosexual partnership.

Authors: Becker Catherine , Davis Justine , Byrd Daiyonna , Colley Anna , Martin Scott , Barrett Tyler
Published: July 2022

Management of diabetic foot ulcers (DFUs) presents challenges to even the most experienced wound care providers. Because of the chronic, non-healing nature of many DFUs, advances in the treatment and care of this disease process are particularly relevant. This case study aims to report the efficacy of the application of dehydrated amniotic membrane allograft (DAMA) to a diabetic foot ulcer. The patient in this study is a 44-year-old male who presented with an aggressive infection on his right foot, which resulted in an open wound of 18 months duration. This patient received weekly applications of dual-layer DAMA over seven weeks. Upon examination at the initial application, the wound was classified as a Wagner grade 3 with necrosis of the underlying muscle. Upon inspection at the final visit, the wound was closed entirely. The results that were shown include improvements in the size, depth, edges, necrotic tissue amount, and epithelization of the wound. This case study demonstrates that the ap-plication of DAMA has the potential to augment the body’s natural DFU healing response; however, future nonrandomized and randomized controlled trials are needed to establish its efficacy further.

Situbondo is one of the best mango producer city with a distinctive mango taste compared to other regions in East Java. Mango production in Situbondo in 2015 reached 222,471 quintals. One of the damage to post-harvest mango products is due to anthracnose disease. The purpose of this study was to determine the effect of hot water treatment in inhibiting anthracnose disease and maintaining the quality of mangoes. The study was conducted at the Plant Clinical Laboratory in January 2019 at the Faculty of Agriculture, University of Jember. The study design used was a completely randomized design with two factors, namely washing temperature (59 ± 1 ° C, 53 ± 1 °C, normal water temperature) and storage temperature (15.1 ± 1 ° C and 18.1 ± 1 ° C). Washing with a temperature of 53 ± 1 ° C can be used to clean fruit. Treatment with low temperature (15.1 ± 1 ° C and 18.1 ± 1 ° C) resulted in inhibiting changes in weight loss, fruit hardness, acid content (total titrated acid), and total dissolved solids while another treatment, 53 ± 1 ° C washing temperature with storage temperature 15.1 ± 1 ° C gives a good appearance that suppress the development of anthracnose, and inhibit fruit discoloration.
SARS-CoV-2 Intermittent Virulence as A Result of Natural Selection
Authors: Rubio-Casillas Alberto , Redwan Elrashdy M. , Uversky Vladimir N.
Published: July 2022

For the first time in history, we have witnessed the origin and development of a pandemic. To handle the accelerated accumulation of viral mutations and to comprehend the virus' evolutionary adaptation in humans, an unparalleled program of genetic sequencing and monitoring of SARS-CoV-2 variants has been undertaken. Several scientists have theorized that, with the Omicron surge producing a more contagious but less severe disease, the end of COVID-19 is near. However, by analyzing the behavior shown by this virus for 2 years, we have noted that pandemic viruses do not always show a decreased virulence. Instead, it appears there is an evolutionary equilibrium between transmissibility and virulence. We have termed this concept “intermittent virulence”. The present work analyzes the temporal and epidemiological behavior of SARS-CoV-2 and suggests that there is a high possibility that new virulent variants will arise in the near future, although it is improbable that SARS-CoV-2´s virulence will be the same as was seen during the pandemic phase.

In videos, the human's actions are of three-dimensional (3D) signals. These videos investigate the spatiotemporal knowledge of human behavior. The promising ability is investigated using 3D convolution neural networks (CNNs). The 3D CNNs have not yet achieved high output for their well-established two-dimensional (2D) equivalents in still photographs. Board 3D Convolutional Memory and Spatiotemporal fusion face training difficulty preventing 3D CNN from accomplishing remarkable evaluation. In this paper, we implement Hybrid Deep Learning Architecture that combines STIP and 3D CNN features to enhance the performance of 3D videos effectively. After implementation, the more detailed and deeper charting for training in each circle of space-time fusion. The training model further enhances the results after handling complicated evaluations of models. The video classification model is used in this implemented model. Intelligent 3D Network Protocol for Multimedia Data Classification using Deep Learning is introduced to further understand space-time association in human endeavors. In the implementation of the result, the well-known dataset, i.e., UCF101 to, evaluates the performance of the proposed hybrid technique. The results beat the proposed hybrid technique that substantially beats the initial 3D CNNs. The results are compared with state-of-the-art frameworks from literature for action recognition on UCF101 with an accuracy of 95%.
Alternative Paradigms in Animal Health Decisions: A Framework for Thinking beyond Money
Authors: Noguera Z. Liz Paola , Hartnack Sonja , Torgerson Paul R.
Published: July 2022

Zoonoses are diseases transmitted from (vertebrate) animals to humans. Control and prevention of these diseases require an appropriate way to measure health for prudent and well-balanced decisions in public health. We propose a framework that aims to explore, understand and open up a conversation about the non-monetary value of animals through environmental and normative ethics. As an example of its application, participants can choose what they are willing to give in exchange for curing an animal in hypothetical scenarios selecting a human health condition to suffer, the amount of money, and lifetime as a tradeoff. We believe that considering animals beyond their monetary value in public health decisions will contribute to a more rigorous assessment of the burden of zoonotic diseases, among other health decisions. This method might help us complement the existing metrics in health, adding more comprehensive values for animal and human health for the “One Health” approach.

Published: July 2022

As solar energy is a low-cost and clean energy source, there has been a great deal of interest in how to harvest it. To absorb solar energy efficiently, we have designed a broadband metamaterial absorber based on the principle of Fabry–Pérot (FP) cavity and surface plasmon resonances (SPRs). We propose a broadband perfect absorber consisting of a four-layer structure of silica-tungsten-silica-titanium (SiO2-W-SiO2-Ti) for the incident light wavelength range of 300–2500 nm. The structure achieves perfect absorption of incident light in the wavelength range of 351.8–2465.0 nm (absorption >90%), with an average absorption of 96.3%. The advantage of our proposed structure is that it combines the characteristics of both high and broadband absorption and has a high overall absorption efficiency for solar radiation. It is also independent of polarization and insensitive to incident angle. We investigated how absorption was affected by different structures, materials, geometrical parameters, and refractive indices for different dielectric materials, and we explored the reasons for high absorption. This structure is refractory and ultra-thin, and it offers a good trade-off between bandwidth and absorption. It therefore has premium application prospects and value.
Pharmacotherapy for the Secondary Prevention of Suicide: Leads from the Social Pain Hypothesis
Authors: Rajkumar Ravi Philip
Published: July 2022

Suicidal behaviour is a public health problem whose magnitude is both substantial and increasing. Since many individuals seek medical treatment following a suicide attempt, strategies aimed at reducing further attempts in this population are a valid and feasible secondary prevention approach. An evaluation of the available evidence suggests that existing treatment approaches have limited efficacy in this setting, highlighting the need for innovative approaches to suicide prevention. Existing research on the neurobiology of social pain has highlighted the importance of this phenomenon as a risk factor for suicide, and has also yielded several attractive targets for pharmacological preventive strategies. In this paper, the available evidence related to these targets is synthesized and critically evaluated. The way in which social pain is related to the “anti-suicidal” properties of recently approved treatments, such as ketamine and psilocybin, is also examined. Such strategies may be effective for the short-term reduction of suicidal ideation and behaviour in individuals who have made a suicide attempt suicide prevention, particularly in cases where social pain is identified as a contributory factor. These pharmacological approaches may be effective regardless of the presence or absence of a specific psychiatric diagnosis.
Indoor Scene Recognition via Object Detection and TF-IDF
Authors: Heikel Edvard , Espinosa-Leal Leonardo
Published: July 2022

Indoor scene recognition and semantic information can be helpful for social robots. Recently, in the field of indoor scene recognition, researchers have incorporated object-level information and shown improved performances. This paper demonstrates that scene recognition can be performed solely using object-level information in line with these advances. A state-of-the-art object detection model was trained to detect objects typically found in indoor environments and then used to detect objects in scene data. These predicted objects were then used as features to predict room categories. This paper successfully combines approaches conventionally used in computer vision (YOLO) and Term Frequency-Inverse Document Frequency (TF-IDF). These approaches could be further helpful in the field of embodied research and dynamic scene classification, which we elaborate on.

Authors: Fahlefi Rizal
Published: July 2022

Utilizing Zakat through a variety of productive programs can improve the welfare of the Muslim community and foster a sense of mental independence among them. Through the Boerka Superior Goat Breeding Center Program in Tanah Datar Regency, West Sumatra, this study aims to investigate how zakat is utilized based on the local geographical potential. Case study methodology is used as the qualitative research approach. Interviews and observations are employed as data collection techniques. The data analysis was conducted using the interactive data analysis model. According to the findings, the model consists of three phases: planning, implementation, and monitoring and evaluation. Several activities comprise the preparation of the program, including the formation of a management team, the selection of areas and mustahiks, and the provision of goats, forage seeds, and mentors. As part of the program's implementation, selected mustahiks will receive assistance in the form of training in recording, pen construction, disease prevention, and feed processing. During the monitoring and evaluation phase, the team conducted routine and ongoing monitoring and assessed the program's progress. This new basis in the utilization of zakat must be considered and implemented by zakat institutions, as it is insufficient to consider only the human factor, as local potential factors, including geographical potential, are also important in the utilization of zakat. Using zakat in a manner that prioritizes local geographical potential is anticipated to significantly enhance the quality of life for mustahiks.

Effect of Water on Mechanical Properties and Fracture Evolution of Fissured Sandstone under Uniaxial Compression: Insights from Experimental Investigation
Authors: Song Cheng , Feng Guorui , Qian Ruipeng , Cui Jiaqing , Wang Kai , Wen Xiaoze , Bai Jinwen
Published: July 2022

Preexisting discontinuities and the water affect the fracture evolution process as well as the rock stability the most extensively. To ensure operational safety, the effects of water on the mechanical properties of fissured rock masses must be understood well. In this study, a series of uniaxial compressive tests is conducted on both dry and saturated fissured specimens with varying fissure angles. Real-time acoustic emission and digital image correlation are applied to monitor the fracture evolution process. The failure mode is investigated by identifying the types of cracks present in the ultimate failure forms of the fissured specimens. The results indicate that (1) the saturated and dry specimens exhibit significantly different strengths and stiffnesses, wherein the saturated specimens exhibit weaker strength by 25.64%–32.59% and a lower elastic modulus by 20.30%–29.22%. (2) The fissure angle and water jointly control the failure mode of fissured sandstone. (3) The observed fracture evolution processes can be classified into six distinct stages to facilitate the understanding of rock failure mechanisms. (4) The presence of water accelerates the nucleation of microcracks at the tips of the prefabricated fissures, enlarges the range of microcrack coalescence, and facilitates the emergence of unstable cracks owing to an increase in pore water pressure and a decrease in the friction resistance of crack surfaces.
Pressure Transient Behaviors of Discretely Fractured Reservoirs Using a Numerical Discrete Fracture Model
Authors: Chen Zhiming , Zhou Biao , Zhang Shaoqi , Yu Wei
Published: July 2022

The conventional dual-porosity model (Warren and Root 1963) may not apply to naturally fractured reservoirs (NFRs), which have poorly connected fractures. To narrow this gap, a new discrete fracture model (DFM)-based numerical well-testing model is developed for pressure transient analysis in vertical wells interacting with natural fractures (NFs). The numerical model is based on a DFM and unstructured perpendicular bisector (PEBI) grid system.

The accuracy and practicality of the proposed model have been demonstrated by model verifications with a commercial numerical software. The results show that the flow regimes of the vertical well interacting with NFs can be divided into wellbore storage and skin effects, bilinear flow, linear flow, radial flow, NF effect, and boundary-dominated flow. This is the radial flow of the formation before pressure propagates to NFs, which is virtually quite different from that in the conventional dual-porosity model. However, there are no bilinear and linear flow stages in the vertical well interacting with no NFs. It is found that the vertical well interacting with NFs has a lower pressure depletion. It is also found that the “V-shape” caused by the NF effect in the pressure derivative curve becomes deeper when there are more NFs, longer NFs, and higher fracture conductivity. Furthermore, the “V-shape” appears earlier, and the duration of the NF effect is longer as the number of NFs increases. Besides, with the decrease of the distance between the fracture and the well, the impacts of NFs on pressure transient behaviors of the vertical well are more significant. This work provides a meaningful way to understand the pressure transient behaviors of discrete NFs.

Authors: Tolani Manoj , Bajpai Ambar , Balodi Arun , Sharma Sunny , Singh Rajat Kumar
Published: July 2022

This work proposes an energy-efficient duty-cycle-based hybrid medium access control protocol. The proposed protocol optimally adjusts the turn-on and off time of the trans-receiver radio to save energy consumption. Both cluster head and sensing devices save energy by estimating the utilization of slots. In reserved slot duration, each sensor device checks its buffer status in a regular interval and turns off its radio when the buffer becomes empty. Each sensor device transmits a slot utilization status to the cluster head device. Cluster head device also turn-on and off its radio based on slot utilization status of sensing devices. A duty cycle approach is proposed for optimal energy consumption. The proposed protocol uses less energy than existing equivalent protocols, according to the mathematical and simulation results. For simulation study, the network is analysed for low, medium, and high data traffic conditions. Simulation results depict, exactly similar results of analytical and mathematical analysis prove the validity of the work.

Introduction: The burden of hernia is disproportionately high in low-to-middle income countries, due to the lack of fundamental resources needed to effectively diagnose and manage cases. This study explored the patterns of hernia, haematological profile, and predictive ability of blood cell indices. Methods: Fifty-four subjects: 27 hernia patients and 27 healthy controls were included in this single-centre, unmatched case-control study. Hernia was diagnosed using physical examination and ultrasound scan. Haematological indices of each subject were measured with an automated blood cell counter. Results: Herniae recorded were 92.59% inguinal, and 3.7% each of epigastric and uterine prolapse. Hernia was prevalent in males (85.2%, p = 0.008) and older subjects ≥ 53 years (48.1%, p = 0.004). HgB (p = 0.006), MCHC (p ≤ 0.001), and RDW-CV (p = 0.042) were significantly elevated in strangulated than non-strangulated hernia and controls, while Abs GRAN (p = 0.024) was decreased in non-strangulated than strangulated hernia and controls. MCHC (AUC = 0.947 [0.895–0.999], p ≤ 0.001) was the most sensitive predictor of herniation followed by age (AUC = 0.750 [0.610–0.889], p = 0.002); HgB (AUC = 0.718 [0.580–0.857], p = 0.006); and RDW-CV (AUC = 0.700 [0.559–0.840], p = 0.012). Also, MCHC (AUC = 0.831 [0.723–0.938], p ≤ 0.001); HgB (AUC = 0.738 [0.590–0.887], p = 0.005); and RBC (AUC = 0.671 [0.502–0.840], p = 0.045) respectively, were significant predictors of strangulation. Conclusion: Gender and age were significantly associated with hernia. Inguinal hernia and strangulation were common in the study setting, especially, among males. Also, there were significant variations in erythrocyte- and leucocyte indices among hernia patients. Erythrocyte indices were significant predictive biomarkers for hernia and strangulation. CBC is a useful test for early detection of herniation and strangulation.

Authors: Mueller Sandy , Fink Madeleine , Hense Joerg , Comino Maria Rosa Salvador , Schuler Martin , Teufel Martin , Tewes Mitra
Published: July 2022

Background.
Despite that early integration of palliative care is recommended in advanced cancer patients, referrals to specialisedana palliative care (SPC) frequently occur late. Well-defined referral criteria are still missing. We analyzed indicators associated with early (ERs) and late referral (LRs) to SPC of a high volume outpatient unit of a German comprehensive cancer center.
Methods.
Characteristics, laboratory parameters and symptom burden of 281 patients at first SPC referral were analyzed. Timing of referral was categorized as early, intermediate and late (> 12, 3–12 and < 3 months before death). Ordinal logistic regression analyze was used to find factors related to referral timing. Kruskal-Wallis test was used to determine symptom severity and laboratory parameter in each referral category.
Results.
LRs (50.7%) had worse scores of weakness, loss of appetite, drowsiness, assistance of daily living (all p < 0.001) and organisation of care (p < 0.01) in contrast to ERs. The mean symptom sum score was significantly higher in LRs than ERs (13.03 vs. 16.08; p < 0.01). Parameters indicative of poor prognosis, such as elevated LDH, CRP and neutrophil-to-lymphocyte ratio (NLR) (p < 0.01) as well as the presence of ascites (p < 0.05), were significantly higher (all p < 0.001) in LRs. In univariable analyzes, psychological distress (p < 0.05) and female gender (p < 0.05) were independently associated with an ER.
Conclusion.
A symptom sum score and parameters of poor prognosis like NLR or LDH might be useful to integrate into palliative care screening tools.

Objects from the Thamar regional museum in Yemen were used in the investigation. In addition to a thick layer of light-green/brown corrosion result, they also had a rust-colored black and brown layer with tiny pieces and a scattering of pale green. Corrosion and its products will be examined in-depth in this study, which will assist us in better understanding the corrosive causes and degradation processes, as well as to identify the metals that comprise the chosen objects produced during long-term entombment. Both items' samples were investigated using Metallographic Microscope (ME) and Scanning Electron Microscope (SEM) for this purpose, while corrosion products were evaluated by using x-ray diffraction (XRD), while the bulk elements of the objects were determined using x-ray fluorescence (XRF). Copper, atacamite, and paratacamite have been identified by XRD analysis as the corrosion products of the leaded bronze alloy. Microscopy shows that the two items have been damaged in certain areas. Chemical cleaning was selected for the treatment of the artifacts based on the information gathered. To investigate the synergistic impact of adding 25 ppm of potassium iodide (KI) to the stock solution of the corrosion inhibitor sodium (Z)-4-oxo-4-p-tolyl-2-butenoate, in this work, the effect of potassium iodide as an improvement chemical was examined (SOTB). For the preservation of old leaded bronze items, this combination has been tested. Synergistic effects between KI and the chosen inhibitor were shown to be beneficial.

Published: July 2022

Background: Tumor mutation burden (TMB) has been considered biomarker for using of immune checkpoint inhibitors(ICIs), but whole exome sequencing(WES) and cancer gene panel(CGP) based on next generation sequencing for TMB detection are costly. Here, we use transcriptome data of TCGA to construct a model for TMB prediction in gastrointestinal tumors.Methods: Transcriptome data, somatic mutation data and clinical data of four gastrointestinal tumors from TCGA, including esophageal cancer (ESCA), stomach adenocarcinoma (STAD), colon adenocarcinoma (COAD) and rectal adenocarcinoma (READ). Using R, we performed visual analysis of somatic mutation data, differentially expressed genes (DEGs) function enrichment analysis, gene set enrichment analysis (GSEA), and estimated the value of TMB in clinic. Finally, a deep neural network (DNN) model was constructed for TMB prediction.Results: Visualization of somatic mutation data summarized the classification of mutation, frequency of each mutation type, and top-mutated genes. GSEA showed the enrichment of CD4+/CD8+ T cells in the high TMB group and the activation of tumor suppressing pathways. Single-sample GSEA (ssGSEA) found that the high-TMB group had higher level of multiple immune cells infiltration. In addition, distribution of TMB was related to age, M stage, N stage, AJCC stage, and overall survival. After model optimization with the genetic algorithm, in the training set, validation set, and testing set, the Pearson relevance coefficient r between predicted values and actual values reaches 0.98, 0.82, and 0.92, respectively; the coefficient of determination R2 is 0.95, 0.82, and 0.7, respectively. Conclusion: TMB correlates with clinicopathological parameters in gastrointestinal carcinoma, and patients with high TMB have higher levels of immune infiltration. In addition, the DNN model based on 31 genes predicts TMB of gastrointestinal tumors in a high accuracy.

Eggshell is environmental waste that is used daily, inexpensively, and has no economic feasibility in recycling, so, it is regarded as one of the ecologically beneficial additions to improve the physical and mechanical characteristics of polymers. In this work copolymer of (p-phenylenediamine/glycerol) was created via chemically oxidative polymerization with potassium persulfate as an oxidant at different ratios of 1:1, 1:2, and 2:1. The prepared copolymers were treated with eggshell nano, carbon nanotube, and (eggshell nano + carbon nanotube) with altered concentrations of 0.02gm (1%) and 0.04 gm (2%). These prepared samples were described using FT-IR, Raman spectra, H1NMR, and XRD. The morphology has been deliberate by TEM. It is observed that the presence of (eggshell nano + carbon nanotube) enhanced the thermal stability of the copolymers. The conductivity with a ratio of 1:2 of (p-phenylenediamine/glycerol) was 8.46x 10− 6 which is the highest value of the other ratios. The copolymers in presence of 0.04gm (2%) of (eggshell nano + carbon nanotube) for ratio 1:1, 1:2 and 2:1, reaches to 5.46x 10− 4, 1.2x 10− 3 and 1.8x10− 5 respectively. The hardness value increases in the weight of 0.04 gm (2%) (eggshell nano + carbon nanotube) more than the weight of 0.02 gm (1%) for all ratios of the copolymers. The hardness value in presence of (eggshell nano + carbon nanotube) at load 1Kg was high and out of the scale.

During the process of the high-speed urbanization in Chinese cities, traditional districts renewal is attracting more and more attention. Up to now, the social, economic, political status, and the interaction between each factor have been seriously discussed on urban traditional districts. However, the effects on urban microclimate and the residential living conditions in traditional districts are not well discussed. However, it is strongly related to the living comfort and citizens’ well-being. In this research, two typical traditional districts in Xi’an are selected as case study. According to the original situation of building functions and the community characteristics, two renewal plans are proposed by adding vegetation in open spaces (V), and adding vegetation combined with building redevelopment (V&B), in order to balance the living convenience and thermal environment. Via ENVI-met simulation, the effects of the district renewal plans on thermal environment includes wind speed, air temperature, and mean radiant temperature are evaluated. This study provides method of environmental evaluation for traditional districts renewal, which contributes to sustainable urban planning in historical districts, and provides recommendations for related policy development.

Published: July 2022

The aim of the study was to compare the efficiency of pharmaceuticals and personal care products (PPCP) removal in the waterworks Káraný (Czech Republic) and Dresden-Hosterwitz (Germany). Both waterworks use a similar technology of drinking water production (combination of bank filtration and artificial recharge) and have similar river water quality (Jizera and Elbe river). A comparison of two-years monitoring results shows a high efficiency of removing PPCP contained in river water. However, at both waterworks there are groups of substances for which natural treatment steps alone are not sufficient. In the case of Káraný it is Benzotriazole, Sulfamethoxazole and Methylparaben, in the Dresden waterworks it is Oxypurinol, Sulfamethoxazole, Carbamazepine and Lamotrigine.

Sustainable wastewater management in an industry is required to avoid widespread water scarcity problems. In this study, chitosan zinc oxide nano-adsorbent was synthesised and obtained a particle size of 88.35 ± 2.89 d.nm. Chitosan zinc-oxide nano-adsorbent coated sand filter bed was developed by coating CZnO with sand, and characterised by considering its adsorption properties as well as its surface morphology, crystallinity, and functional groups. Batch adsorption experiments were conducted to optimise the process parameters such as CZnO coating dosage, contact time, pH, and initial concentration of biological oxygen demand and chemical oxygen demand. Adsorbent efficiency was studied in treating simulated and real milk processing industry wastewater. The percent reduction efficiency of organic pollutants was found to increase with the increase in contact time and coating dosage of chitosan-zinc oxide nano-adsorbent. Adsorption was rapid and occurred within 140 min with different coating dosages. The percent reduction of biological oxygen demand and chemical oxygen demand increased with an increase in pH. The optimum solution pH for adsorption of both the pollutants from synthetic solution was 6.0. The equilibrium concentration of synthetic solution reached 200 mg/L and 250 mg/L for both pollutants. Four regeneration cycles could be applied without compromising the adsorption efficiency of the filter bed. The performance of the filter bed was compared with previous studies, and it was found to have excellent adsorption efficiency. Hence, chitosan zinc-oxide nano-adsorbent coated sand could be used as a promising filter bed for the removal of organic load from milk processing industry wastewater.
