A dual port Cylindrical Dielectric Resonator Antenna (CDRA) has been demonstrated for K band (22 GHz) applications in this work. The antenna offers polarization diversity which is introduced by degenerating HE11δ modes in a single CDRA. Orthogonal feed lines produce two modes which are perpendicular so they don’t interfere with each other and offer excellent linear polarization diversity in orthogonal planes. Since the CDRA size is compact, the feed lines have been modified to assure the generation of desired modes. A detailed investigation into the generation of resonant modes along with parametric analysis is presented. Measured results show fractional bandwidth of 9.5% and 18.18% for both port 1 and port 2 respectively. Isolation of better than 32 dB has been measured between the two ports through transmission coefficient. Difference of about 20 dB between co-polarization and cross polarization in both planes for broadside direction has been measured which endorses the polarization diversity performance of the antenna. Different MIMO performance parameters including envelope correlation coefficient, total active reflection coefficient, channel capacity loss and mean effective gain have been measured to assess the performance of the design.

Recent advances in wearable electronics have been propelled by the rapid growth of microelectronics and Internet of Things. The proliferation of electronic devices and sensors relies heavily on power sources, predominantly batteries, with significant implications for the environment. To address this concern and to reduce carbon emissions, there is a growing emphasis on renewable energy harvesting technologies, among which textile‐based triboelectric nanogenerators (T‐TENGs) stand out as an innovative and sustainable solution due to having the interesting characteristics like large contact area, lightweight design, flexibility, comfort, scalability, and breathability. T‐TENGs can harness mechanical energy from human movement and convert it into electric energy. However, one of the challenges is low electric power output, which can be addressed by meticulous selection of material pairs with significant differences in work function and optimizing contact areas. The incorporation of carbon‐based nanomaterials, such as carbon nanotubes and graphene, emerges as a key strategy to enhance output. This review delineates recent progress in T‐TENGs incorporating carbonaceous nanofillers, comprehensively addressing fundamental classification, operational mode, structural design, working performance, and potential challenges that are hindering commercialization. By doing this, this review aims to stimulate future investigations into sustainable, high‐performance smart wearables integrated with T‐TENGs.

Background: Otomycosis is a superficial mycotic infection of the external auditory canal. Clinical presentation, along with otoscopic findings, is sufficient to make the diagnosis in most of the cases. Treatment includes aural cleaning followed by the instillation of anti-fungal ear drops. In the recent years, there has been an increasing trend of antifungal resistance for the commonly used antifungals such as fluconazole and clotrimazole. Drug sensitivity patterns have also shown variability from one region to another. Aims and Objectives: To evaluate the clinico-mycological profile along with antifungal susceptibility pattern and treatment outcome of primary otomycosis. Materials and Methods: A total of 230 clinically diagnosed patients of primary otomycosis were included in this prospective study. Microbiological causes were evaluated by KOH wet mount and culture of samples collected from external auditory meatus using sterile swabs. Fungal culture was done on Sabouraud dextrose agar with chloramphenicol at 25°C and 37°C. Anti-fungal susceptibility test was done by disk diffusion method using medium Muller-Hilton agar with glucose and methylene blue. All the patients were treated with the removal of fungal debris with topical clotrimazole instillation and were followed up after 7 days. Non-responders were treated with topical itraconazole. Results: Male-to-female ratio in study participants was 1:1.3. The most frequently observed risk factor was the instillation of oil in the ear (20%). Ear itching was the commonest symptom (70.9%). Positive fungal growth was seen in 203 (88.3%) cases. Aspergillus was present in 185 (91.1%) cases, followed by Candida in 18 (8.9%) cases. Voriconazole had the highest sensitivity followed by itraconazole. 167 (83.3%) patients responded to primary treatment (topical Clotrimazole), 36 (16.7%) patients were non-responders. Conclusion: All the clinically suspected patients should be evaluated for fungal positivity, which may further guide in the selection of appropriate anti-fungal agents. Awareness regarding the predisposing factors for otomycosis in the general population may result in a significant drop in the incidence of otomycosis.

Failure investigation was conducted on magnetic drive centrifugal sealless pumps that had only been operating for six months and were already struggling to rotate. It was discovered that hydrocarbon sludge and other debris had blocked the lubricating channel, which is meant to provide pathways for cooling and lubricating the pump's inner magnetic and containment shell. Further investigation revealed that service water had contaminated the process fluid, precipitating calcium carbonate upon contact with the amine solution and clogging the flushing line. An additional duplex strainer was installed on the repaired pumps, and adequate precautions were taken to prevent water contamination.

The contraction rates of weft knitted plain jersey fabric and some patterned single jersey fabrics with respect to machine gauge were determined. Fabric samples were knitted using cotton yarn at various stitch length values on a positive feed based multi feeder circular weft knitting machine. Widthwise contraction rates of the resulting fabric samples were then calculated using the values of wales per inch and needles per inch. It was discovered that when stitch length increased, the value of the contraction rate decreased. Additionally, it was found that the knitted stitches (knit, tuck and miss) greatly impacted how much the fabric contracts. Fabric with miss stitches showed higher contraction than fabrics knitted with tuck stitches. However, knit-miss based single jersey fabrics showed less contraction than plain single jersey fabrics while all courses are knitted at the same course length value. It was also observed that contraction rates also change due to different positioning of tuck and miss loops in the patterned structures.

Weft knit fabrics are popular for traditional wear because of their elastic and light structures, gentle smoothness, low production costs, and high productivity. However, due to asymmetrical loop formation, spirality causes serious dimensional problems in single jersey fabrics (SJF). This study investigates the effects of various parameters on spirality, including yarn count, yarn tension, tightness factor, stitch length, fabric weight per unit area, machine speed, needle gauge, and number of feeders. All the sample fabrics were knitted with Z-twisted, combed, 100% cotton yarns and went through a scouring, bleaching, and whitening process before being dried in the same conditions. Fabric spirality was found to increase as stitch length, number of feeders, yarn count, and twists per unit length in constituent yarn increased whereas the tightness factor and needle gauge, on the other hand, had opposite effects on spirality. The test results were analyzed statistically, and a significant impact was discovered.

Introduction Diabetes has become a global epidemic. Hearing loss has been long associated with diabetes. Brainstem Evoked Response Audiometry (BERA) is an objective, non-invasive, electro diagnostic test that not only evaluates the functional integrity of the subcortical auditory pathway but also provides topo-diagnosis of hearing loss. This study aims to identify the role BERA in detecting hearing loss early in diabetic patients. Materials and Methods In this study a total of 210 patients were taken and subjected to blood glucose levels followed by PTA were divided into two groups. Group I (n=105) consisted of diabetic patients with sensorineural hearing loss (SNHL) and Group II (n=105) had age and sex matched non-diabetics with SNHL. All the patients were evaluated with BERA. Results All the patients were subjected to Brain Stem Evoked Response Audiometry (BERA). Absolute latency of Wave I, III, V, I-III, III-V and I-V were assessed for both the ears. In both ear Absolute latency were significantly higher in diabetics as compared to non-diabetic patients Conclusion The findings of present study showed that the severity of hearing loss was significantly higher in diabetic patients as compared to non-diabetic controls. Level of glycemic control showed a possible link with severity of hearing loss.

Combination of alumina (Al2O3) and zirconia (ZrO2) as cutting tool have been established themselves as a dominant in ceramic category for dry machining. The mechanical properties of Al2O3-ZrO2 cutting tool were critically dependent on its density and hardness, which affected by the powder preparation and sintering processes. This paper present the effect of sintering temperature on density, hardness and tool wear of Al2O3-ZrO2 cutting tool. Specific composition of 80-90 wt% Al2O3 and 10-20 wt% ZrO2 powders were mixed and ball milled for 12 hours. These powders then were compacted in the form of RNGN120600 designated cutting tool by using manual hydraulic press before undergone secondary compaction by Cold Isostatic Press. The compacted powders then were sintered from 1200oC to 1400oC at constant 9 hours soaking time. For each sintered cutting tool, evaluation has been made based on the density and hardness. By using AISI 1045 as a workpiece material, the wear performance of the selected cutting tools were evaluated within 200-350 m/min cutting speeds, 0.1 mm/rev feed rate and 0.5 mm depth of cut. The results shows that the sintering temperature at 1400oC and 9 hours soaking time produced maximum relative density and hardness for 90 wt% Al2O3 and 10 wt% ZrO2 at 94.17% and 63.4 HRC respectively. Cutting tool contained with 80 wt% Al2O3 and 20 wt% ZrO2 contributed maximum relative density of 97% and hardness of 70.07 HRC. Maximum tool life recorded was 156s at 200 m/min cutting speed. Wear mechanisms of fabricated cutting tool dominated by the notch and flank wear at the early stage of machining and formation built up edge at the end of machining process.

Antimicrobial resistance has emerged as a global health crisis and, therefore, new drug discovery is a paramount need. Cannabis sativa contains hundreds of chemical constituents produced by secondary metabolism, exerting outstanding antimicrobial, antiviral, and therapeutic properties. This paper comprehensively reviews the antimicrobial and antiviral (particularly against SARS-CoV-2) properties of C. sativa with the potential for new antibiotic drug and/or natural antimicrobial agents for industrial or agricultural use, and their therapeutic potential against the newly emerged coronavirus disease (COVID-19). Cannabis compounds have good potential as drug candidates for new antibiotics, even for some of the WHO’s current priority list of resistant pathogens. Recent studies revealed that cannabinoids seem to have stable conformations with the binding pocket of the Mpro enzyme of SARS-CoV-2, which has a pivotal role in viral replication and transcription. They are found to be suppressive of viral entry and viral activation by downregulating the ACE2 receptor and TMPRSS2 enzymes in the host cellular system. The therapeutic potential of cannabinoids as anti-inflammatory compounds is hypothesized for the treatment of COVID-19. However, more systemic investigations are warranted to establish the best efficacy and their toxic effects, followed by preclinical trials on a large number of participants.
