Protection for teachers means an effort to avoid them from any kind of violence, threat, discrimination, injustice, criminalization, and deviant treatment coming from whether students, parents, or society. This study aims to examine three forms of protection for teachers in serving the job as educators namely in the realm of law, profession, and intellectual properties. It uses a juridical-sociological method in the qualitative data compilation technique. The data was obtained through in-depth interviews and desk study. Meanwhile, the data analysis is through reduction and conclusion making. It results in three conclusions. 1) The law protection for teachers comes in the form of advocacy, law dissemination, protection from any type of violence, friendly students’ education format, students' character building, and good communication with students' parent. 2) The protection for teacher in the realm of profession is through reasonable earning and freedom of speech. 3) The protection for teachers' intellectual property is through motivating them to be productive even though the results have not been well patented.

Legal Mismatch on Illegal Sand Mining in Indonesia: an Example in Sleman, Indonesia
Authors: Putri Paramitha Susanti , Raharjo Trisno 
Published: January 2022

The purpose of this study was to determine the implementation of regulations on illegal sand mining activities in Sleman Regency. The approach used is a legal regulation approach.
The results of the study found that the implementation of regulations in illegal sand mining activities in Sleman Regency had not been implemented properly. In fact there are many violations committed by miners in running their businesses, and many mining activities are carried out illegally without having a mining business permit. In addition, the obstacle faced in implementing the regulation is that the miners believe that the sand they take is a blessing due to the eruption of Mount Merapi, so they assume that they can mine in large quantities. In addition, there are limitations to regional budgets that often become obstacles in implementing reclamation as an act of restoring environmental damage carried out by the Environment Agency both at the provincial and district / city levels as well as the limited number of personnel and experts.

Published: January 2022

Summary
Produced water is a major challenge in the oil and gas industry, especially with the aging of oil fields. Proper treatment of produced water is important in reducing the environmental footprint of oil and gas production. On offshore platforms, hydrocyclones are commonly used for produced-water treatment. However, maintaining the efficiency of hydrocyclones subjected to plant disturbances is a difficult task owing to their compact nature. This paper describes a new experimental test rig built at the Department of Mechanical and Industrial Engineering at the Norwegian University of Science and Technology for testing industrial-scale hydrocyclones. The test setup can emulate first-stage separation and create plant disturbances, such as changes in flow rate, oil concentration, and oil droplet distribution at the inlet of the hydrocyclones. Also, the setup is capable of testing different control algorithms, which helps to maintain the efficiency of hydrocyclones in the presence of such disturbances. The test rig is equipped with various instruments that can monitor such parameters as pressure, flow, temperature, and oil concentration. A typical pressure drop ratio (PDR) control scheme for hydrocyclones is tested in the test rig, which can control the disturbances in the inflow rate. The PDR control scheme does not detect disturbances in the inlet oil concentration and changes in droplet distribution, and these scenarios are shown experimentally in this paper.
Experimental Study of Proppant Bridging in a Model of a Hydraulic Fracture

Published: January 2022

SummaryIn this article, we investigate formation of the local clogging (bridging) of proppant in a channel with gradually narrowing walls. The experimental facility allows us to simulate the process of the proppant transport in a hydraulic fracture by reproduction of the characteristic channel width, velocity of slurry, rheology of fracturing fluids, and typical concentrations of proppant. The goal of the study is to give qualitative description of the dynamics of the congestion of the proppant up to the complete blockage of the flow. In contrast to common practice of imposing bridging criteria by postulating certain threshold value of the width to proppant size ratio, we demonstrate that the bridging process involves several stages: clogging of two to three particles, growth of stable “islands,” connection of the islands by arches, and, finally, the total sandout of the cell by the bridged proppant. The observations of the paper gives better understanding of the bridging process giving the directions for more precise numerical simulations.

Abstract
BackgroundResults from recent clinical trials on bone marrow mononuclear cell (BM-MNC) transplantation show that this intervention can help reduce the incidence of heart failure (HF) after acute myocardial infarction (AMI). However, no study has evaluated the effect of the transplantation of mesenchymal stem cells (MSCs) on a clinical endpoint such as HF.MethodsThis single-blinded, randomized, multicenter trial aims to establish whether the intracoronary infusion of umbilical cord-derived Wharton’s jelly MSCs (WJ-MSCs) helps prevent HF development after AMI. The study will enroll 360 patients 3 to 7 days following AMI. Only patients aged below 65 years with impaired LV function (LVEF < 40%) will be included. They will be randomized (2:1 ratio) to either receive standard care or a single intracoronary infusion of 107 WJ-MSCs. The primary outcome of this study is the assessment of HF development during long-term follow-up (3 years).DiscussionData will be collected until Nov 2024. Thereafter, the analysis will be conducted. Results are expected to be ready by Dec 2024. We will prepare and submit the related manuscript in accordance with the SPIRIT guidelines. This study will help determine whether or not the infusion of intracoronary WJ-MSCs in patients with AMI will reduce the incidence of AMI-induced HF.Trial RegistrationClinicalTrials.gov, NCT05043610, Registered 14 September 2021 - Retrospectively registered, https://clinicaltrials.gov/ct2/show/NCT05043610
Serotonin regulation of behaviour via large-scale neuromodulation of serotonin receptor networks
Authors: Salvan Piergiorgio , Fonseca Madalena , Winkler Anderson , Beauchamp Antoine , Lerch Jason , Johansen-Berg Heidi 
Published: January 2022

Abstract
Although we understand how serotonin receptors function at the single-cell level, what role different serotonin receptors play in regulating brain-wide activity and, in turn, human behaviour, remains unknown. Here, we developed transcriptomic-neuroimaging mapping to characterise brain-wide functional signatures associated with specific serotonin receptors: serotonin receptor networks (SRNs). Probing SRNs with optogenetics-fMRI and pharmacology in mice, we show that activation of dorsal raphe serotonin neurons differentially modulates the amplitude and functional connectivity of different SRNs, showing that receptors’ spatial distributions can confer specificity not only at the local, but also at the brain-wide, network-level. In humans, using resting state fMRI, different sets of SRNs are linked to different behavioural phenotypes. These results provide compelling evidence that heterogeneous brain-wide distributions of different serotonin receptor types may underpin behaviourally-distinct modes of serotonin regulation. This suggests that dorsal raphe serotonin neurons may regulate multiple aspects of human behaviour via modulation of large-scale receptor networks.

Published: January 2022

Abstract
Purpose
Determine health professionals’ (HPs’) perceptions of oral mucositis (OM), including clinical presentation of chemotherapy (CT)-induced vs radiation therapy (RT)-induced OM, its assessment and management.
Methods
HPs involved in the care of head and neck cancer (HNC) patients receiving RT to the oral cavity/oropharynx and haematopoietic stem cell transplantation (HSCT) patients receiving mucositis-inducing CT regimens were invited to participate in a customised 20-question survey. Themes included OM presentation, assessment and management.
Results
Survey response rate was 81.4%. Most were nurses (33%) and specialist doctors/dentists (25%). Majority (45%) identified as part of the haematology service, followed by radiation oncology (32%). Most haematology and radiation oncology HPs (89% and 70%, respectively) agreed/strongly agreed that OM impacted patients’ ability to complete treatment. There was a significant association (p<0.01) between HPs’ specialty and their perceptions of OM manifestations. Most radiation oncology (85%) and all oral medicine HPs agreed/strongly agreed that clinical manifestations of CT-induced OM and RT-induced OM were different, whereas haematology HPs varied in their perceptions (11% disagreed, 41% were neutral and 48% agreed/strongly agreed). There was uncertainty regarding differences in management of CT vs RT-induced OM: 30% of haematology HPs and 45% of radiation oncology HPs agreed/strongly agreed but most (52% and 45%, respectively in each group) responded “neutral.”
Conclusion
OM was recognised to adversely impact HSCT and HNC RT patients’ ability to complete treatment. There were differences in HPs’ perceived understanding of OM manifestations and management. Interventions to address these may reduce unwanted variations in patient care and outcomes.

Abstract
Superconductors and magnetic materials, including molecules, are key ingredients for quantum and advanced spintronic applications. However, only a little is known about how these materials are mutually influenced at their interface in hybrid architectures. Here, we show that a single layer of magnetic molecules, the Terbium(III) bis-phthalocyaninato (TbPc2) complexes, deposited on a superconducting Pb(111) surface is sensitive to the topology of the intermediate state of the superconductor, namely to the presence and evolution of superconducting and normal domains due to the magnetic field screening and penetration. The evidence of this sensitivity is found in the magnetisation dynamics of the TbPc2 sub-monolayer in its paramagnetic regime showing the fingerprint of the topological hysteresis of the superconducting substrate. This study reveals the great potentialities hold by thin layers of magnetic molecules for sensing local magnetic field variation in hybrid molecular/superconductor architectures, including spin resonators or spin injection devices for spintronics applications.
A Machine Learning Analysis of COVID-19 Mental Health Data
Authors: Rezapour Mostafa , Hansen Lucas 
Published: January 2022

Abstract
In late December 2019, the novel coronavirus (Sars-Cov-2) and the resulting disease COVID-19 were first identified in Wuhan China. The disease slipped through containment measures, with the first known case in the United States being identified on January 20th, 2020. In this paper, we utilize survey data from the Inter-university Consortium for Political and Social Research and apply several statistical and machine learning models and techniques such as Decision Trees, Multinomial Logistic Regression, Naive Bayes, k-Nearest Neighbors, Support Vector Machines, Neural Networks, Random Forests, Gradient Tree Boosting, XGBoost, CatBoost, LightGBM, Synthetic Minority Oversampling, and Chi-Squared Test to analyze the impacts the COVID-19 pandemic has had on the mental health of frontline workers in the United States. Through the interpretation of the many models applied to the mental health survey data, we have concluded that the most important factor in predicting the mental health decline of a frontline worker is the healthcare role the individual is in (Nurse, Emergency Room Staff, Surgeon, etc.), followed by the amount of sleep the individual has had in the last week, the amount of COVID-19 related news an individual has consumed on average in a day, the age of the worker, and the usage of alcohol and cannabis.

Published: January 2022

Abstract
The stock-recruitment relationship (SR), customarily used in fisheries assessment, can be used to analyze demographic data of sea turtles to infer changes in hatchling production (R) as a function of nester abundance (S), recruitment rates and the influence of environmental conditions on these population features. The SR Cushing model (R=aS^b), where a and b are the model parameters) is well-suited for representing the dynamics of recovering populations, such as the green turtle (Chelonia mydas) in Campeche, Mexico. This study aimed to explore the SR Cushing model using a time series of the abundance of nesters and hatchlings (1984–2020). By applying local regressions (9-yr moving windows), we found that the time series of parameter b (the change in R as a function of S) and the recruitment rate (hatchlings per nester) were inversely correlated with a 26-yr cycle of the Atlantic Multidecadal Oscillation –sea surface temperature (SST), over the Atlantic– (r^2=0.83) and (r^2=0.64), respectively, at a 3-yr lag). Model diagnostics using the time-dependent Cushing model substantiated that the log-normal distribution of hatchlings of C. mydas in Campeche depends on the abundance of nesting females and on a low frequency SST signal (r^2=0.98). The positive trend in nester numbers of green turtles in Campeche during the past 44 years may be the result of persistent conservation efforts, while the drastic and sporadic changes in the growth rate of annual arrivals and hatchling production are suggestive of population dynamics driven by low frequency, basin-wide environmental signals.

Abstract
Perinatal hypoxia-ischemia (HI) is a major health issue with no effective therapies beyond head cooling. Notably, male infants are at a greater risk for HI and exhibit more extreme deficits than females. Extensive clinical evidence indicates that perinatal HI impacts the developing cerebellum, yet this region has been largely ignored in preclinical models. Using a modified version of the Rice-Vannucci rat model for HI injury at postnatal day 10, we find reductions in dendritic complexity of Purkinje neurons in males one week later. Females exhibited modest but opposite effects, with slight increases in dendritic complexity, based on Sholl analysis. A custom-made NanoString panel for quantifying mRNAs associated with development, inflammation, and sex differences found almost no commonality in the response to HI in males versus females, with males up-regulating genes associated with microglia activity whereas females increased expression of a protective complement protein, but also of enzymes associated with endocannabinoids and prostaglandins. Both sexes exhibited a reduction in the GABA-synthetic enzymes, GAD-65 and GAD-67, after HI, suggesting increased excitotoxicity, but why males suffered more damage to the Purkinje neurons is unknown.
