    Here we consider the results of direct measurements of muons in extensive air showers with zenith angles θ45\theta \le 45^{\circ} and energy above 101710^{17} eV, obtained at the Pierre Auger Observatory and Yakutsk array. In both experiments muons were registered with underground scintillation detectors with 1.0×secθ\approx 1.0 \times \sec\theta GeV energy threshold. Measured density values were compared to theoretical predictions calculated within the framework of the QGSJet-II.04 hadron interaction model. They differ by factor 1.53±0.131.53 \pm 0.13(stat). We demonstrate that this difference is due to overestimation of muon densities by 1.22 times and underestimation of primary energy by 1.25 times in the Auger experiment.Comment: 9 pages, 11 figures, 3 tables.

    In-medium properties of the light and heavy-light mesons in a light-front quark model

    Full text link
    We investigate the in-medium properties of pseudoscalar and vector mesons with the light-light and heavy-light quarks in a light-front quark model, using the in-medium quark properties computed by the quark-meson coupling model. Both models are constructed on an equal footing with the constituent quark degree of freedom. Here, we particularly focus on the weak decay constants and distribution amplitudes (DAs) of the mesons in symmetric nuclear matter. We find that the weak decay constants decrease as nuclear density increases for π\pi, KK, DD, and BB pseudoscalar as well as ρ\rho, KK^{*}, DD^{*}, and BB^* vector mesons, where their properties in free space have good agreement with the available experimental and lattice QCD data. A larger reduction is found for the light-light quark pseudoscalar mesons, while a smaller reduction is found for the heavy-light quark vector mesons, in particular, with the bottom quark. We discuss the effect of the vector potential on the weak decay constants and present our predictions for the in-medium modifications of DAs. Also, a comparison with the free space lattice QCD data is made.Comment: 17 pages, 11 figure

    Crack development in a changing environment is the controlling factor for the stability and strength of expansive soils. Expansive soils exhibit large volumetric changes with changes in their moisture conditions that may occasionally lead to reduced bearing capacity and foundation failures. This study purports to model crack initiation and its spatial progression in relation to the moisture content and drying period, respectively. Volumetric soil shrinkage is determined using high-definition digital camera imaging and Vernier scale methods, while the soil settlement under vertical shrinkage deformation could be captured through a tensile stress model for soils. It was revealed that a small change in suction could trigger crack initiation, which would propagate further under different environmental conditions. Furthermore, it was observed that the crack volume increased rapidly at specific moisture content and could penetrate as deep as 1 m after nearly 1.5 months that is fully consistent with the current model predictions. A comparison between the performance of the model proposed in this study and that of two existing models shows that the former predicts the vertical shrinkage strain values in closer agreement with those observed experimentally and is less conservative than those predicted by both models. Nevertheless, the findings from this study could be used to quantify the detrimental behavior of expansive soil present in pavement subgrades and shallow foundations for lightweight structures

    The article is devoted to analysing activities of the infectious disease unit of a medical institution in one of Ukrainian regions. The unit is designed for intensive care of patients. The study main goal is to develop a strategy for further development of this unit to improve quality of its services and patient satisfaction. During the research, the initial conditions for the in-patient medical care provision were discussed. A comprehensive analysis of activities and structural problems within the infectious unit was carried out. Based on the study results, a strategic plan for further development was generated to enhance the unit efficiency and quality of its provided medical services. During analysing the infectious unit work, it was found that the in-patient care provision meets the worldwide infectious care norms. In the conditions of reforming the Ukrainian medical industry, many issues remain unresolved (in particular, restructuring and improvement of the healthcare system as a whole and that of the infectious disease unit). The latter plays an important role in creating a high-quality national program for medical service provision by healthcare institutions. Therefore, we succeed in improving resilience in the face of public health threats and risks. The analysis showed current positive trends in understanding the importance of this structural unit activities within the healthcare system. Besides, new ways of its modernisation are found. The authors substantiate this area development requires the national quality control indicators, the marketing policy improvement as well as the strengthened organisational and methodological role of the infectious disease service in healthcare institutions. Specific recommendations were formulated regarding ways to develop the infectious disease unit. They will help raise service satisfaction among patients of medical institutions. The obtained results are of practical importance and can be used in managing healthcare institutions at the national and regional levels

    Head Lice Eradication Efforts in a Group Home Environment: Yayasan Griya Asih Orphanage – A Case Study

    Children living in orphanages are generally vulnerable to close-contact transmission diseases, including head lice infestation. The clinical manifestation of head lice infestation was relatively mild, such as itchy scalp, and hence it is often overlooked as a community health issue. Education plays an essential role in preventing re-infection and eradicating head lice infestation. The treatment options include chemical treatment using pediculicides and physical management by shaving the head and manually removing the parasite. This community service activity aimed to eradicate head lice from Yayasan Griya Asih Orphanage. A series of three activities were conducted at Yayasan Griya Asih Orphanage in Central Jakarta. Each activity was done around one month apart to evaluate the effectiveness of treatment. Firstyear medical students were recruited to participate in these activities to familiarize them with real-world community health problems. Student volunteers helped applied pulse doses of Permethrin 1% shampoo and provided health education activity. Fiftyfive Yayasan Griya Asih Orphanage residents joined this activity from mid-October until December 2022. Residents were instructed not to share their personal items to prevent re-infection. Health education activities were done using one-to-many followed by a one-on-one format. In conclusion, head lice infestation screening is essential in crowded environments, and permethrin 1% pulsed dose followed by personalized health education activities and pest control effectively broke the disease transmission chain and eradicated the head lice infestation

    Effect of fermented sarco oyster extract on age induced sarcopenia muscle repair by modulating regulatory T cells

    Sarcopenia is an age-related, progressive skeletal muscle disorder involving the loss of muscle mass and strength. Previous studies have shown that γ-aminobutyric acid (GABA) from fermented oysters aids in regulatory T cells (Tregs) cell expansion and function by enhancing autophagy, and concomitantly mediate muscle regeneration by modulating muscle inflammation and satellite cell function. The fermentation process of oysters not only increases the GABA content but also enhances the content of branched amino acids and free amino acids that aid the level of protein absorption and muscle strength, mass, and repair. In this study, the effect of GABA-enriched fermented sarco oyster extract (FSO) on reduced muscle mass and functions via Treg modulation and enhanced autophagy in aged mice was investigated. Results showed that FSO enhanced the expression of autophagy markers (autophagy-related gene 5 [ATG5] and GABA receptor-associated protein [GABARAP]), forkhead box protein 3 (FoxP3) expression, and levels of anti-inflammatory cytokines (interleukin [IL]-10 and transforming growth factor [TGF]-β) secreted by Tregs while reducing pro-inflammatory cytokine levels (IL-17A and interferon [IFN]-γ). Furthermore, FSO increased the expression of IL-33 and its receptor IL-1 receptor-like 1 (ST2); well-known signaling pathways that increase amphiregulin (Areg) secretion and expression of myogenesis markers (myogenic factor 5, myoblast determination protein 1, and myogenin). Muscle mass and function were also enhanced via FSO. Overall, the current study suggests that FSO increased autophagy, which enhanced Treg accumulation and function, decreased muscle inflammation, and increased satellite cell function for muscle regeneration and therefore could decrease the loss of muscle mass and function with aging
