Authors: ÇALIŞIR Vahit
Published: September 2022

Assuming that people are aware that climate change will result in disasters, it is reasonable to suppose their current behavior will alter to avoid this destruction. Studies about climate change have been conducted for a long time trying to raise people's awareness practically everywhere in the world. From this perspective, this study aims to see if people are aware of climate change and if they are struggling to address their worries. The Iskenderun area is a coastal city experiencing the worst effects of climate change. As a result, the research The content of which was mentioned above.was applied to people of all ages, genders, and educational levels, and a survey to 330 people was conducted N=330). According to the study, individual awareness of the potential effects of global climate change in Iskenderun district is as strong as it is in the rest of the globe. However, even though the association between participant awareness and solution initiatives is positive and significant, the coefficient r = 0.310 does not indicate a strong relationship. Even though support is low (about %10), it appears that scientific methods can be used to persuade the people of Iskenderun and boost support for a sustainable city. Another suggestion is to direct public resources into the development of communication methods to increase awareness.

This study was carried out to evaluate the effect of pre-treatment technique (blanching) and temperature on the drying characteristics of the red date variety. Thin layer drying experiments were conducted at varying drying temperatures of 50, 60 and 70 °C using electrical laboratory oven and cabinet dryer with a constant air velocity of 1.4 m/s. Other sets of samples were blanched at 50 °C for 2-, 5- and 10-minutes before being dried at varying drying temperatures of 50, 60 and 70 °C respectively under the same drying conditions. The drying process took place mainly in the falling rate period indicating that the mechanism that governed moisture movement in the samples was diffusion. The drying curve showed that blanched red date fruits had higher drying rate than the un-blanched samples. The result is useful for farmers, researchers, and the processing industry in designing a reliable machine for processing red date fruit which will boost the small and medium scale production of the fruit in Nigeria.

Comparison of Dexmedetomidine Vs Buprenorphine as Adjuvants to Intrathecal Bupivacaine for Bilateral Total Knee Replacement Surgeries - Randomised Controlled Trail
Authors: Bansal Dr. Ishan , Kaur Dr. Jasleen , Goyal Aman
Published: September 2022

Introduction: The duration of analgesia produced by local anaesthesia is limited if administered alone. Therefore, supplementation of local anaesthetics with adjuvants helps to improve the efficacy of the sub-arachnoid block, especially in long-duration surgeries like bilateral total knee replacement. The most preferred drugs used are opioids, but due to new drug development like dexmedetomidine has been introduced and proved to be effective adjuvant. Aim: This study was conducted to evaluate and compare the characteristics of subarachnoid blockade and hemodynamic stability. The VAS was used pre-operatively, after intrathecal, immediately post-operatively, and on the basis of the need for rescue analgesia or epidural. Materials and Methods: A total of 150 patients were taken aged between 30-80 years classified as American Society of Anesthesiologists (ASA) undergoing bilateral TKR under neuraxial anaesthesia were included in the study. The patients were randomly allotted to two groups to receive 4.0 mL of 0.5% hyperbaric bupivacaine with 0.2 mL of dexmedetomidine (5 μg) intrathecally (Group D; n = 75) and another group to receive 4.0 mL of 0.5% hyperbaric bupivacaine with 0.2 mL of buprenorphine (60 μg) intrathecally (Group B; n = 75). Results: There was no significant difference between groups regarding demographic characteristics, no significant difference in hemodynamic variables. The motor, sensory, blockade, and time of rescue analgesia were significantly prolonged in Group D compared to Group B. Hence, Group D was far better than Group B in terms of duration of analgesia, time of onset of sensory block, time for maximum levels of sensory block, and modified bromage score. Conclusion: Intrathecal dexmedetomidine, compared to intrathecal buprenorphine, causes prolonged anaesthesia and analgesia with a reduced need for sedation and rescue analgesics. Also, reduced adverse effects are seen with intrathecal dexmedetomidine. Complications with Group D ............

Published: September 2022

Mucoceles of the paranasal sinuses are benign expansive pseudo-cystic lesions, affecting mainly adults. These rare lesions are usually evolving at low noise and are most often revealed by neurological or ophthalmological complications. We report a case of a recurrent fronto-ethmoidal mucocele with orbital extension. This was a 69-year-old patient with a previous history of endoscopic marsupilization of mucocele by a private practitioner 10 years back, who presented frontal headaches associated with a left-sided forehead swelling and chronic left proptosis evolving for 3 years, in whom clinical examination revealed fluctuant swelling present in the forehead region above the left eye and unilateral left sided proptosis. Cranio-facial computed tomography (CT) and magnetic resonance imaging (MRI) were in favor of a left fronto-ethmoidal mucocele with homolateral intra-orbital extension. The patient was operated by an endoscopic surgical approach. The outcomes were favorable with regression of headaches and resolution of proptosis. The fronto-ethmoidal mucocele, although benign, has an aggressive potential in the absence of treatment either towards the endocranium or the orbit. Imaging plays a crucial role in the diagnosis, preoperative planning and monitoring of mucoceles and CT and MRI should be used as complementary investigations of sino-nasal pathology. Treatment of mucoceles is surgical and recurrences are uncommon. Although the fronto-ethmoidal is a benign lesion, it is may be responsible for complications involving the functional or even vital prognosis. An early diagnosis and treatment allow to improve mucoceles outcomes.

Retroperitoneal paraganglioma is a rare neoplasm that develops from chromaffin cells that secrete catecholamines in the sympathetic ganglia. They are frequently functional and may be benign or malignant depending on the presence of metastasis and/or the occurrence of recurrence. Different imaging modalities play a crucial role in detecting these tumors. The typical CT appearance of PG is that of a well limited isodense mass with an intense contrast enhancement. On MRI, the mass presents an isosignal or hyposignal in T1 and hypersignal in T2 with an early and intense enhancement. The final diagnosis is based on histological and immunohistochemical findings and the surgical excision is the mainstay of the treatment. However, these tumors are often difficult to diagnose and treat. We report a case of a 30-year-old female patient who presented with a 3 months history of constipation, revealing on computed tomography (CT) a retroperitoneal mass lateralized on the right with a close connection to the inferior vena cava. Urine normetadrenaline (metanephrine) was elevated at 451 ug/24h. Neck and chest CT scan and scintigraphy with 123-I labeled metaiodobenzylguanidine (MIBG) were negative. Complete resection of the tumor was performed. The histological examination and immunohistochemical analyses concluded the diagnosis of a paraganglioma.

Through advances of Internet-of-Things (IoT) technologies, smart home concepts have become increasingly prevalent, and they are gradually being adapted in society. Apart from cost efficiency and user convenience, implementing monitoring and control in a smart home has the potential to also increase energy efficiency. In this paper, a web-based monitoring and temperature control for an air conditioning (AC) system is proposed. The long-ranged AC control system consists of three ZigBee devices that enable wireless communication between the temperature, remote, and router modules which sends data over the internet using ESP8266. A web-based interface was also developed to display room temperature, last temperature of the AC, and a button to activate/deactivate the AC. The results showed that the prototypical system fulfilled the expected functionality, and that ZigBee is a robust choice of communication protocol.

Authors: Hasan Md. Kamrul
Published: September 2022

Solar energy is a renewable source of energy. Usage of this energy can reduce the carbon emissions on the environment. To store electric energy produced from solar panels, a battery is used named solar battery. The capacity of storing electricity depends on the active materials of the battery cells. Normally the capacity of a lead acid battery depends on active materials, size of the plates, gravity of the acid, construction of the grid of the plates. In this research, all other variables responsible for battery capacity (gravity of acid, size of the plates, construction of grid etc.) are constant and only one variable is active materials of the plates. 4 batteries containing different amounts of active material are used to identify the best combination which gives the highest value of active mass utilization coefficient.

Bullous pemphigoid (BP) is an autoimmune sub-epidermal bullous disorder with a complex etiopathogenesis, predominately affecting the elderly. We report a case of COVID vaccination- induced BP, in a 30-year-old previously healthy Indian male who presented with a 1month history of itchy generalized vesiculo-bullous eruption that developed 3 days after receiving the first dose of the COVID vaccination. Histological examination and direct immunofluorescence study showed a sub-epidermal blister with a dermal inflammatory infiltrate and linear epidermal staining of IgG and C3 along the basement membrane zone in an n-serrated pattern. Treatment with oral prednisolone and oral doxycycline resulted in significant improvement in his condition. To our knowledge, there are limited case reports to date particularly in the Middle-East, which describe BP triggered by COVID vaccination.

Published: September 2022

Number of risk factors has been associated with pelvic inflammatory disease, such as age, previous sexually transmitted infection, previous PID, multiple sexual partners, or an intrauterine contraceptive device. Women who use an intrauterine device for contraception are at least 2-4 times more likely to develop PID than non-users. Women who have had PID are twice as likely to develop the infection as those who have never had it. A history of a prior uncomplicated gonococcal infection is more common among women with PID than among women without disease. The present cross- sectional study was conducted in J.N. Medical College and Hospital (J.N.M.C.H.), Aligarh Muslim University, Aligarh. Permission for doing the study was taken by the Board of Studies in the Department of Community Medicine, Jawaharlal Nehru Medical College, Aligarh Muslim University, Aligarh. The study was carried out for a period of one year, from 1st August 2001 to 31st July 2002. The present study was carried out among ever married females in the reproductive age group of 15 to 49 years. Women, who gave positive history of PID, were asked to give their consent for the study. Their refusal was taken as exclusion criteria. Females with PID who were menstruating or who had taken antibiotic within the previous month were also excluded from the study. A total of 350 ever married females were selected from the Gynaecology OPD of J.N. Medical College Hospital (n=170), Urban Health Training Centre (n=100) and Rural Health Training Centre (n=80).A detailed clinical history and clinical examination were recorded on a pre-formed and pre tested proforma. All the females under study were subjected to per vaginal examination. The percentage of those female was more who used any cloth during menstruation. Out of 350 patients, 7.4% ga ve history of T.B, 24% gave history of previous episodes of PID, 12.0% gave history of MTPs/D&Cs. 5.1% had adopted IUCDs as a method of family planning.1.71% cases gave history of removal of IUCDs because of some complications. 75.0% of 80 cases (who adopted family planning) used IUCDs, OCPs and ligation. IUCDs, OCPs, ligation and irregular use of condoms probably increase chances of PID.

Published: September 2022

The inter-critical heat affected zone (ICHAZ) appears to be one of the most brittle sections in the welding of high-strength micro-alloy steels (HSLA). Following multiple heating cycles in the temperature range between Ac1 and Ac3, the ICHAZ undergoes a strong loss of toughness and fatigue resistance, mainly caused by the formation of martensite-austenite constituent (MA). The presence of micro-alloying elements in HSLA steels induces variations in the formation of some microstructural constituents, more or less beneficial, which allow to improve the mechanical performance of a welded joint. The behavior in the inter-critical region of a S355 grade steel with 0.1wt% V addition is reported in this paper.  Five double-pass welding thermal cycles were simulated using a dilatometer, with the maximum temperature of the secondary peak in the inter-critical area, in the range between 720 ° C and 790 ° C. The residual austenite dependence on inter-critical temperature is analyzed and related to the hardness behavior.

Published: September 2022

This work is devoted to the thermal stability and thermal expansion of dual-phase AlFeCoNiCu as-cast high-entropy alloy of equiatomic composition. The mix FCC + BCC phases is in AlFeCoNiCu high entropy alloy. According to characterized by EDS-analysis, Fe and Co are almost uniformly distributed in both phases in comparison with other elements. The BCC phase is rich in Ni and Al, and the FCC phase is Cu. Our measurement results of hardness and elastic modulus values for inter dendrites (FCC phase) and dendrites (BCC phase) of as-cast AlFeCoNiCu alloy showed the difference between there. Hardness values for inter dendrites and dendrites: 3.4±0.4GPa and 4.1±0.6GPa. Elastic modulus values for inter dendrites and dendrites: 130.5±2.0GPa and 166.5±5.6GPa. The thermal stability of the phases presented in AlFeCoNiCu as-cast high-entropy alloy has been studied with dilatometry and differential scanning calorimetry (DSC). The DSC thermogram shows an endothermic peak at 1000K. The coefficient of thermal expansion (CTE) curve shows linear increment from room temperature up to 1370K from (10.6 ± 0.3)×10-6K−1 to (27.7 ± 0.3) ×10-6K−1. The CTE temperature curve also shows the peak at 1000K. The peaks in the CTE temperature and the DSC curve suggest a phase transformation with increasing temperature up to~1000K.

Published: September 2022

The present work deals with analysis of mechanical performance and microstructural appearance of quenched and tempered SS-304 welded joints made by MIG welding technique. Since welding involves a critical solidification and thereby lots of internal stresses. Hence, heat treatment becomes important for removing stresses. In the present work, two SS-304 welded plates were heat treated. First plate was in quenched condition, and another was in tempered state. In both the plates, mechanical properties like tensile strength, impact strength, and hardness were analyzed. In addition, the microstructural attributes of base metal, heat affected zone and welded joints in both the welded plates were analyzed through optical microscope. The fractography analysis was also carried out in this study to get information about failure characteristics of samples after tensile testing. A significant change in mechanical properties, such as, 150% improvement in toughness, 7% reduction in weld-zone hardness, 3% improvement in yield strength and 6% reduction in ultimate tensile strength was obtained after tempering work. Also, the tempering process had reformed the grain structure by creating twins in base metal, and lathy δ ferrite & γ+δ lamella in HAZ. The martensite formed in quenched specimen had been completely recovered into fine γ+δ matrix.
NbC TRANSFORMATION DURING AGING IN HP40-Nb HEAT RESISTANT ALLOY
Authors: Sosa Lissarrague Matías Humberto , Lanz César Armando
Published: September 2022

In this work, the evolution of MC-type Nb-rich primary carbides in a 35Ni-25Cr-Nb-type refractory alloy, commonly known as HP40-Nb, and its transformation into Ni-Nb silicide known as G-phase (Ni16Nb6Si7), has been studied. For this purpose, the experimental technique of scanning electron microscopy was used together with X-ray microanalysis to detect changes in the chemical composition of niobium carbide over time and at a given aging temperature. The microstructure of the studied alloy, in its as-cast condition, consists of an austenitic matrix strengthened by a network of primary eutectic-like carbides rich in chromium and niobium of the M23C6 and MC types, respectively. During aging of the alloy at high temperatures, microstructural changes take place such as the secondary precipitation of M23C6 type carbides and the transformation of the primary Nb-rich carbide towards the Ni-Nb-rich silicide. It has been found that the transformation begins at the interface of the niobium carbides with the matrix, progressing towards their interior with the development of aging.

The welding processes were done at 1400 rpm and 2000 rpm rotational speeds with two different frictional loads 2000 N and 2500 N for 5 sec and 7 sec welding times. The welded joints were subjected to tensile and hardness tests. The heating-cooling cycles through the welding process were monitored. The microstructure investigation was performed using optical and scanning electron microscopes (SEM). The effect of welding conditions on the ultimate tensile strength (UTS) results of AA 6061 and AA 6061/GNPs were completely studied in details. There is no big detectable variation in the mean hardness values due to the GNPs addition. The best welding conditions for achieving the highest mechanical properties were defined. The presence of GNPs in the welded joints results in lower heating at the welded joint at the same welding conditions. Finer grain structure and homogeneous distribution for the GNPs within the welding zone were observed.

BACKGROUND: Chronic inducible urticaria is a group of diseases that is characterized by the development of wheals, angioedema, or both in response to specific triggers for 6 weeks. According to global scientific international literature, the occurrence of chronic inducible urticaria is 0.5% in the general population and approximately 20%30% in all chronic urticarias. The prevalence of chronic inducible urticaria has no statistical data in the Russian Federation.
AIM: This study aimed to evaluate the region-specific epidemiology of different forms of chronic inducible urticaria.
MATERIALS AND METHODS: The analysis is based on the number of unique cases extracted from the medical care records in the adults segment of the digital platform United medical information and analytical system (UMIAS) (outpatient forms) in Moscow from 2017 to 2021, including keyword search.
RESULTS: This study indicated that the prevalence of chronic inducible urticaria in Moscow is correlated with published global epidemiological data. Among patients with chronic inducible urticarial, females predominate (74.2%), and the median age was 43.8 years (37 years in males and 46.4 in females). The most common form in all verified cases of chronic inducible urticaria is symptomatic dermographism (11.12%), followed by contact urticaria (5.36%), cholinergic urticaria (2.28%), cold urticaria (1.92%), delayed pressure urticaria (0.36%), vibratory urticaria (0.11%), aquagenic urticaria (0.1%), and heat urticaria (0.08%). Chronic inducible urticaria rates in Moscow are high, which increase as in global practice. This research has limitations, including the lack of ubiquitous implementation of standard protocols of provocation testing in outpatient units and the low percentage of using validated questionnaires in the routine management of patients with chronic inducible urticaria.
CONCLUSIONS: Further studies dedicated to this topic are greatly necessary to answer a wide spectrum of questions, including the diagnosis process and evaluation of the severity of chronic inducible urticaria, comorbid conditions, and optimization of the treatment protocols adapted for the particular phenotype.

Depression is a psychiatric condition characterized by a persistent sense of sadness and dullness. It is also known as a severe burdensome problem or clinical sorrow, and it impacts how a person feels, thinks, and behaves and triggers a slew of emotional and physical issues. Various components are liable for this issue, and many related sicknesses are expanding because of this infection. It is not just at risk for well-being perils, yet also produces perilous social offense, like self-destruction and family misuse. In this study, we used machine learning methods such as Random Forest (RF), Logistic Regression (LR), and Naive Bayes (NB). We also used accuracy, precision, recall, and F1-score to survey the exhibition assessment of arrangement results. These machine learning algorithms developed and analyzed Confusion matrices through data augmentation to assess the classification performance. This study used machine learning technologies to predict depression and revealed the significance of the trait. Then we have tried to utilize an oversampling technique that shows the distinction in model execution. Indeed, we wanted to see how well the recommended machine learning algorithms performed before and after rebalancing standardized data. In our suggested framework, the RF classifier performed better with 89% accuracy and 90% precision than other models.

Potassic alteration is a common feature in hydrothermal ore systems, and both its occurrence and degree can be important features applicable to ore deposit exploration. Here we report results from optical cathodoluminescence (CL) and chemical composition investigations on K-feldspar of different origins in and around the Early Cretaceous lode gold deposits in the Xiaoqinling area, located along the southern margin of the North China Craton.

We focus on K-feldspars from an Early Cretaceous biotite monzogranite (G-Kfs), a Paleoproterozoic migmatite (M-Kfs), and a hydrothermal alteration zone of Early Cretaceous gold deposits (H-Kfs). The grain size of G-Kfs ranges from 1 to 4 mm, usually exhibits tartan twinning, and occasionally shows evidence of exsolution. Part of the M-Kfs exhibits tartan twinning, and the grain size shows wide variation (from tens of microns to several centimeters), while the H-Kfs shows no twinning, and the grain size is generally less than 0.5 mm.

Optical CL analyses show that the G-Kfs exhibits two emission bands at around 466–472 and 708–713 nm which occur in multiple, alternating dark red and blue zones. The M-Kfs exhibits blue, red, and/or violet-red luminescence resulting from two emission bands at 446–465 and 694–701 nm. The H-Kfs displays a distinct greenish-yellow luminescence resulting from an emission band at 545–550 nm.

Electron probe microanalyses show that among the three K-feldspar types, the G-Kfs contains higher Na2O (average: 0.71 wt.%) and Al2O3 (average: 18.79 wt.%) and lower K2O (average: 15.62 wt.%), whereas the H-Kfs shows higher K2O (average: 16.31 wt.%) and lower Na2O (average: 0.45 wt.%) and Al2O3 (average: 18.61 wt.%). The K2O, Na2O, and Al2O3 contents of the M-Kfs are intermediate between those of the G-Kfs and H-Kfs. In transitioning from the G-Kfs, M-Kfs, to H-Kfs, it is noted that the concentrations of Sr, Ba, and Pb decrease progressively, whereas W, V, Zn, Mn, Sc, Ge, and Ga gradually increase. Concentrations of La, Ce, and Eu in the H-Kfs are lower than in the G-Kfs and M-Kfs, and the Cr and Cu concentrations in the G-Kfs are the lowest. Scatter diagrams constructed with Sr, Ba, Pb, and Rb concentrations show that the three types of K-feldspars fall into different fields. These, as well as the CL and spectral properties of K-feldspar, can clearly distinguish the K-feldspars of magmatic, metamorphic, and hydrothermal origin in the study area.
