In the face of the climate crisis, sustainability education must include a focus on understandings of socio-ecological systems (SES) and applying systems thinking (ST) skills. This study investigates a Community and Citizen Science (CCS) program designed for elementary school students to collect forest data to better understand their SES and gain insights into wildfire management in a California region recently ravaged by wildfires. We examine the development of fourth-grade students’ systems thinking skills and understandings of SES, seeing these as crucial components toward fostering agency with science to support climate resilience. We found that students were capable of recognizing the intricate impacts of wildfires on interconnected human and ecological systems and demonstrated varying levels of proficiency in systems thinking skills. This place-based CCS program cultivated knowledge and skills in young learners that may contribute to better socio-ecological resilience and proactive sustainability efforts.
Ferric Oxyhydroxylsulfate Precipitation Improves Water Quality in an Acid Mining Lake: A Hydrogeochemical Investigation
Authors: Sultan Khawar , Faraj Turki Kh. , Zaman Qamar uz
Published: December 2023

Hydrogeochemistry of a lignite pit lake in Lusatia, Germany, was investigated. Anoxic groundwater from the dump aquifer rich in FeII (average ~5911 µmol/L) and SO4 (average ~14,479 µmol/L) contents enter the lake as subsurface inflow; oxidation and subsequent precipitation of poorly crystallized Fe-oxyhydroxysulfate (schwertmannite) occurs and causes acidification (pH~2.8). However, the removal of dissolved loads as solid phases significantly improves the groundwater quality of the downgradient as an outflow. The rainwater isotopic values (δD ~−8.88‰ and δ18O ~−65.86‰) closely matched with the groundwater showing very little isotopic modification, which points to a short residence time of groundwater. The displacement of δD and δ18O values (slope = 5.3) from the meteoric water line reflected the evaporative enrichment of the lake water. The isotopic signature also revealed longer residence times of epilimnion than the hypolimnion waters which are dominated by groundwater. The lake is dimictic and showed abrupt changes in physicochemical parameters along the interface (~0.30 m thick) when separating the epilimnion (upper 4 m) from the hypolimnion (bottom 1.5 m). Lake sediments were found to be dominated by clay size fraction occurring as laminations (thickness: 1~0.5 mm) that reflect seasonal sedimentation. Higher schwertmannite formation in the south as compared to the north (recharge side) also serves as a scavenger of potentially toxic elements which is probably a natural solution to man-made problems. Schwertmannite transformation to goethite releases sulfate which is reduced and fixed as secondary sulfide minerals over time. Overall, waters are of a Ca–SO4 to Ca–Mg–SO4 type with distinct inflow (FeII/FeIII > 2.5) and outflow (FeII/FeIII < 0.5) of groundwater.

This article explores the role of creatine supplementation in the processes of oxidative stress during exercise. Oxidative stress is the result of an imbalance between the formation and elimination of reactive oxygen species (ROS), which degrade biogenic substances: deoxyribonucleic acid (DNA), proteins, lipids, and can lead to tissue damage. In the course of physical activity, there is a physiological increase in the processes of oxidative stress. Although intense exercise contributes to oxidative damage to muscle fibers, regular physical activity enhances the ability of cells to eliminate excess ROS. Moderateintensity exercise has been shown to increase antioxidant protection. Endogenous antioxidants cannot completely prevent oxidative damage under physiological and pathological conditions (high-intensity and elevated training). The latter can cause endogenous antioxidant imbalance and increase oxidative stress. Scientific studies show the presence of an antioxidant effect in creatine and demonstrate that the use of creatine supplements increases adaptation to physical activity.

Learning to navigate uncertainty in primary care: a scoping literature review
Authors: Gardner Nick P , Gormley Gerard J , Kearney Grainne P
Published: December 2023

Background

Clinical practice occurs in the context of uncertainty. Primary care is a clinical environment that accepts and works with uncertainty differently from secondary care. Recent literature reviews have contributed to understanding how clinical uncertainty is taught in educational settings and navigated in secondary care, and, to a lesser extent, by experienced GPs. We do not know how medical students and doctors in training learn to navigate uncertainty in primary care.

Aim

To explore what is known about primary care as an opportunity for learning to navigate uncertainty.

Design & setting

Scoping review of articles written in English.

Method

Using a scoping review methodology, Embase, MEDLINE, and Web of Science databases were searched, with additional articles obtained through citation searching. Studies were included in this review if they: (a) were based within populations of medical students and/or doctors in training; and (b) considered clinical uncertainty or ambiguity in primary care or a simulated primary care setting. Study findings were analysed thematically.

Results

Thirty-six studies were included from which the following three major themes were developed: uncertainty contributes to professional identity formation (PIF); adaptive responses; and maladaptive behaviours. Relational and social factors that influence PIF were identified. Adaptive responses included adjusting epistemic expectations and shared decision making (SDM).

Conclusion

Educators can play a key role in helping learners navigate uncertainty through socialisation, discussing primary care epistemology, recognising maladaptive behaviours, and fostering a culture of constructive responses to uncertainty.
A Comprehensive Microservice Extraction Approach Integrating Business Functions and Database Entities
Authors: Bajaj Deepali , Goel Anita , Gupta Suresh
Published: December 2023

Cloud application practitioners are building large-scale enterprise applications as microservices, to leverage scalability, performance, and availability. Microservices architecture allows a large monolithic application to be split into small, loosely coupled services. A service communicates with other services using lightweight protocols such as RESTful APIs. Extracting microservices from the monolith is a challenging task and is mostly performed manually by system architects based on their skills. This extraction involves both: 1) Partitioning of business logic, 2) Partitioning of database. For partitioning of business logic, the existing research studies focus on decomposition by considering the dependencies in the application at the class-level. However, with the passage of time, monolith application classes outgrow their size defying the Single Responsibility Principle (SRP). So, there is a need to consider the code within the classes when identifying microservices. Current studies also lack the partitioning of database and ignore the mapping of Database Entities (DE) to the microservices. In this paper, we present a Comprehensive Microservice Extraction Approach (CMEA) that considers: 1) Both classes and their methods to define and refine microservices, 2) Associate the DE to microservices using newly devised eight guiding rules handling ownership conflicts. This approach has been applied to three benchmark web applications implemented in Java and one in-house application implemented in both Java and Python. Our results demonstrate better or similar software quality attributes in comparison to the existing related studies. CMEA improves software quality attributes by 22%. System architects can easily identify microservices along with their DE using our approach. The CMEA is generic and language-independent so it can be used for any application
A Dual-Objective Approach for Allocation of Virtual Machine with improved Job Scheduling in Cloud Computing
Authors: Sutar Sandeep , Byranahallieraiah Manjunathswamy , Shivashankaraiah Kumarswamy
Published: December 2023

In Cloud Computing (CC) environment, requests of user are maintained via workloads that are allocated to Virtual Machines (VMs) using scheduling techniques which primarily focus on reducing the time for processing by generating efficient schedules of smaller lengths. The efficient processing of requests also needs larger usage of resources that incurs higher overhead in the form of utilization of energy and optimization of cost utilized by Physical Machines (PMs). Assignment of VMs optimally in the environment of CC for jobs submitted by users is a challenge. In order to obtain better solution involving scheduling of jobs to VMs, considering two parameters utilization of energy and cost, we present a dual-objective approach for VM allocation with improved scheduling of jobs in CC environment. The proposed work aimed to build a dual-objective scheduling model for improved job scheduling, focusing on minimization of cost and utilization of energy at a time. For evaluating performance of dual-objective approach, we utilized two types of benchmark datasets and compared with existing approaches such as Whale, Artificial Bee Colony (ABC), Particle Swarm Optimization (PSO) and Metaheuristic Dynamic VM Allocation (MDVMA) techniques. The results obtained from simulation demonstrated that dual-objective approach performs better in the form of minimization of utilization of energy and cost
Healthcare Data Security in Cloud Storage Using Light Weight Symmetric Key Algorithm
Authors: Devi Parthasarathy Vimala , Viswalingam Kalaichelvi
Published: December 2023

Now-a-days, healthcare monitoring system is very much important system in the medical field to know the patient‘s health status immediately. In the proposed system, the sensors are fixed over the patient’s body or placed at some distances around the body to collect patient’s significant parameters like blood pressure, temperature, heart beat rate, etc. These parameters are collected by the healthcare professionals through some connectivity mechanisms like Bluetooth, ZigBee, etc. These significant data will be outsourced to the cloud storage in a secure way to avoid attack from the attackers. So, we need some protection mechanism to safeguard this information. This article proposes a light weight cryptographic algorithm (symmetric key) via random number key generation using Diffie-Hellman key exchange based on Elliptic Curve (ECDH) cryptography. As a result of substituting bytes (S-box) and folding (horizontal and vertical) operations, the proposed symmetric key algorithm achieves the foremost properties of cryptography such as confusion and diffusion quite well. Experimental results showed that the overall execution time of the proposed algorithm is superior to the standard Advanced Encryption Standard (AES) algorithm. The throughput rate of the proposed algorithm is 20.525095 KB/seconds whereas for the standard AES algorithm throughput rate is 18.727215 KB/seconds. So, the proposed algorithm is faster than the existing AES algorithm. Moreover, the construction of S-box, IS-box and the key generation procedures are entirely different in the proposed algorithm so, it increases the complexity for the attacker and it will create confusion to the attacker

Published: December 2023

Саркома Капоши (СК) – системное опухолевое многоочаговое заболевание сосудистого генеза с преимущественным поражением кожи, лимфатических узлов и внутренних органов. СПИД-ассоциированная СК чаще встречается у людей с низким уровнем CD4+ лимфоцитов и определяемой вирусной нагрузкой. Локализация на коже является типичной, однако СПИД-ассоциированная СК может поражать практически все внутренние органы. Данные об особенностях влияния COVID-19 на манифестацию и течение оппортунистических инфекций при ВИЧ-инфекции, и в том числе саркомы Капоши, в настоящий момент ограничены. В работе представлено описание клинического случая сочетанного течения двух заболеваний: коронавирусной инфекции COVID-19 и ВИЧ-ассоциированной саркомы Капоши. СК у пациентки дебютировала с агрессивного поражения желудочно-кишечного тракта (ЖКТ) и легких, а после присоединения COVID-19 молниеносно распространилась на кожные покровы. Поздняя диагностика ВИЧ-инфекции, отсутствие антиретровирусной терапии, выраженная иммуносупрессия способствовали неблагоприятному исходу.

Kaposi’s sarcoma (KS) is a multifocal neoplasm of lymphatic endothelium-derived cells with a primary lesion of the skin, lymph nodes and internal organs. AIDS-associated KS is more common in people with low CD4+ cell count and detectable viral load. Localization on the skin is typical, but AIDS-associated KS can affect almost all internal organs. Data on the features of the impact of COVID-19 on the manifestation and course of opportunistic infections in HIV infection, including Kaposi’s sarcoma, are currently limited. The work presents the description of a clinical case of a combined course of two diseases: coronavirus infection COVID-19 and HIV-associated Kaposi’s sarcoma. KS in the patient debuted with an aggressive lesion of the gastrointestinal tract and lungs, and after the addition of COVID-19, it quickly spread to the skin. Late diagnosis of HIV infection, lack of antiretroviral therapy, severe immunosuppression contributed to the poor outcome.

Introduction: Osteoporosis is a skeleton disease with reduction in bone mass and disruption of the bone microstructure. A rare secondary form is pregnancy-associated osteoporosis. The standard method for determining bone density is DEXA measurement (dual X-ray absorptiometry). With the radiofrequency echographic multi spectrometry (REMS) method this is done using ultrasound without radiation exposure. Osteoporosis often leads to pathological fractures of the vertebrae. In case of severe pain and immobilization vertebroplasty is considered standard procedure. However, it can have side effects such as cement leakage into surrounding tissue, pulmonary embolism and adjacent fractures.

Case: We present a 27-year-old female patient with compression fractures of the Th8 and Th12 5 months after labour. DEXA measurements showed values of the T-score at hip neck -2,5 SD (total) and -3,5 SD (L1-L4) at spine. The fractures of the Th8 and Th12 were then treated with vertebroplasty. A post-operative CT showed cement leakage and extravasation, as well as bilateral cement embolism of the proximal branches of the pulmonary arteries and progression of the height loss of Th5, Th7 and L1.

Discussion: Pulmonary cement embolism is a rare complication of vertebroplasty. Cement leakage is more frequent complication, although most of the time asymptomatic. These risks of complications make the alternative conservative treatment worth considering before proceeding to surgical interventions. Only after failure to achieve adequate pain management kyphoplasty or vertebroplasty should be considered, due to the risks of prolonged immobilization of the patient leading to further bone and muscle loss.

Conclusion: Pregnancy associated osteoporosis is very rare.  The radiation free REMS method is suitable for pregnant women. Vertebroplasty offers pain relief and rapid mobilization of the patient. However, it poses a risk of numerous complications. The osteoporotic fractures of the vertebrae are usually stable and a conservative treatment prior to surgical interventions should always be considered.

Published: December 2023

Here is the overview of the seismicity of the territory of the Republic of Armenia and surrounding countries for 2018 and 2019. More than 4000 local earthquakes have been processed. N=1417 earthquakes for 2018 and N=1416 earthquakes for 2019 were included in the catalogue of the earthquakes of the Republic of Armenia. Within the Republic the highest level of seismic activity is fixed in the north, and in the source zone of the Spitak earthquake 1988, MLV=6.9, I0=10. Analysis of earthquake recurrence graphs for 2018, 2019 showed that the slope of the earthquake recurrence graphs (2018=0.47 and 2019=0.42 respectively) is slightly lower in absolute value than its average value for 1993–2017 (=0.49). Earthquakes felt on the territory of Armenia for 2018 and 2019 are described.

In 2018–2019, the monitoring of seismicity in the Kopetdag region was carried out by a network of 34 seismic stations of the Institute of Seismology and Atmospheric Physics of the Academy of Sciences of Turkmenistan, of which 20 are stationary and 14 are mobile. For two years, 348 earthquakes with KR≥8.6 were registered, for 62 events the focal mechanisms were determined. More than 20 earthquakes were felt in the settlements of Turkmenistan, but only a part of them were localized directly within its borders. The earthquake of January 7, 2018 with KR=12.1 (mb=4.8), located in the Balkhan-Caspian area, was felt with maximum intensity on the territory of Turkmenistan and caused shaking in the city of Turkmenbashi with an intensity of Ii=3–4, and in the city of Balkanabat Ii=2–3. Among seismic events outside Turkmenistan, the earthquakes that occurred in Afghanistan on May 9, 2018 (Mw=6.3) and December 20, 2019 (Mw=6.2) stand out with the highest magnitude and macroseismic manifestations in the territory of Turkmenistan. The shaking intensity from the first event in the nearest settlements of Tajikistan and Afghanistan was Ii=5, and in the Turkmen city of Magdanly (483 km) – Ii=2–3. The second event was felt in Dushanbe (Tadjikistan) up to Ii=4, and in Magdanly (Turkmenistan, =418 km) – up to Ii=2. Among the seismically active areas of the Kopetdag region, the maximum amount of seismic energy in 2018 was released on the territory of the Turkmen-Khorasan area, and in 2019 – in Eastern Turkmenistan. For the Kopetdag region as a whole, seismic activity and corresponding parameters of the seismic regime in 2018 and 2019 decreased significantly compared to their long-term averages.

The seismicity review of Kamchatka and surrounding territories for 2018–2019 is given. In the Kamchatka earthquake catalogue, the minimum local magnitude of completeness is MLmin=3.8, and for the Kamchatka seismically active region (latitude = 50.5–56.5° N, longitude = 156.5–167° E) MLmin=3.7, and for earthquakes with h≥350 km under the Okhotsk sea MLmin=3.8. The Kamchatka earthquake catalogue for 2018–2019, published in the Appendix to this article, includes 3646 events with ML≥3.5; 228 earthquakes with ML=3.65–7.3 were felt in Kamchatka and surrounding areas with seismic intensity I of 1–2 to 6–7 according to the Seismic Intensity Scale-2017 (Russian state standard). For 134 events with ML≥5.0 that occurred in 2018–2019 within the area of responsibility of Кamchatka branch of Geophysical Survey RAS, an attempt to calculate the seismic moment tensor (SMT) was made. The SMT and depth h of the equivalent point source were calculated for 67 earthquakes in 2018 with a range of ML=5.0–7.3, and for 67 events in 2019 with a range of ML=5.0–6.45. The level of seismicity according to the "SOUS'09" scale in 2018 corresponded to the “background increased”, but within the assessment accuracy – “high”; for 2019 it was the “background average”. On December 20, 2018, there was a strong earthquake with Mw=7.3, named “the Angular Uplift earthquake”. This earthquake was the strongest intraplate event, which belongs to the region south of the junction zone of the Kamchatka and Aleutian trenches The earthquake was accompanied by a large number of aftershocks.
