Published: March 2024

Abstract
This research presents the effect of carbon fiber-reinforced polymer (CFRP) on a strength of concrete containing rice husk. Two shapes of columns (circular and square) were used to compare these two types in terms of resistance axial loading. Twelve concrete columns were casting; six are square and others are circular cross-section. All columns of each shape were divided into three groups, and each group consisted of two columns: the first group without CFRP, the second group covered with one layer of CFRP, and the last group covered with two layers of CFRP. The dimensions of the square columns were 300 mm × 300 mm and the height was 900 mm, with reinforced 4–6 mm steel bars. The circular columns were 300 mm in diameter with same height 900 mm and reinforced with 6–6 mm steel bars. Burnt rice husks are added at a rate of 10% of the amount of cement that should be added to the concrete mix. The test results showed the circular columns were the strongest and most resistant to axial loading than square columns. Also, the CFRP wrapping is very effective in strengthening circular concrete columns but significantly less effective in strengthening square concrete columns because the latter have sharp corners and flat sides.

Abstract
The present research work is focused on analyzing the tribological and corrosion impacts of introducing a new metal/bioceramic (Ti/HA) compound into the matrix of the Mg–3Zn alloy. The hybrid composites were developed using the squeeze casting method. The density, microhardness, and microstructure of the developed composite materials were examined. A pin-on-disk tribology meter was used to conduct the tribological study under a phosphate-buffered saline (PBS) lubricating medium. Studies on electrochemical corrosion were carried out in the PBS medium. Incorporating hybrid Ti/HA particles into the Mg–3Zn alloy matrix significantly increased the density and microhardness of the composites. Optical microscopy demonstrates a refined grain size and uniform distribution of reinforced particles, showcasing improved structural integrity. Scanning electron microscopy analysis further confirms the α-Mg and β-Mg–Zn phases. According to the findings of wear tests, the Ti/HA inclusion in the Mg–3Zn (MZ0) matrix increased the resistance to wear behavior. Abrasion, delamination, oxide layer formation, and severe delamination features were observed at the worn surfaces. Abrasive wear happened along with all other wear mechanisms and served as a wear initiator. Potentiodynamic polarization experiments revealed that the corrosion resistance of hybrid composites was increased with the inclusion of 1.5 % HA.

Abstract

Objectives
To assess the effects of an exercise training program combining power-oriented resistance training (RT) and high-intensity interval training (HIIT) on metabolic syndrome (MetS) markers in older people with COPD.

Methods
Twenty-nine older people (66–90 years old) with COPD were randomly assigned to 12 weeks of exercise training (ET; power-oriented RT + HIIT) or a control group (CON). Waist circumference, diastolic (DBP) and systolic blood pressure (SBP), and serum fasting glucose, triglycerides and HDL cholesterol levels were assessed at baseline and after 12 weeks. Linear mixed-effects models were used to assess the effects of the intervention, and data were reported as mean and 95 % confidence interval values.

Results
Waist circumference increased in the CT group, but not in the ET group (2.0 [0.2, 3.7] vs. 1.0 [−1.3, 3.2] cm, respectively). No changes in fasting glucose (−4.1 [−10.3, 2.1] vs. −1.0 [−8.7, 6.7] mg dL−1), triglycerides (3.9 [−13.4, 21.3] vs. −13.9 [−35.6, 7.7] mg dL−1) or HDL cholesterol (1.0 [−3.4, 5.4] vs. 2.9 [−2.6, 8.4] mg dL−1) were found in the CT or ET group, respectively. The ET group exhibited decreased DBP (−5.2 [−9.5, −0.8] mmHg) and SBP (−2.7 [−22.7, −2.7] mmHg), while no changes were found in the CT group (0.3 [−3.2, 3.7] and −3.5 [−11.4, 4.5] mmHg). MetS z-score declined in ET but remained unchanged in CT (−0.88 [−1.74, −0.03] vs. 0.07 [−0.62, 0.76], respectively).

Conclusions
A 12-week exercise training program led to a reduction in blood pressure and MetS z-score in older people with COPD.

Published: March 2024

In brief
In light of the increasing age of first-time fathers, this article summarizes the current scientific knowledge base on reproductive aging in the male, including sperm quality and health impacts for the offspring. The emerging role of NAD decline in reproductive aging is highlighted.

Abstract
Over the past decades, the age of first-time fathers has been steadily increasing due to socio-economic pressures. While general mechanisms of aging are subject to intensive research, male reproductive aging has remained an understudied area, and the effects of increased age on the male reproductive system are still only poorly understood, despite new insights into the potential dire consequences of advanced paternal age for the health of their progeny. There is also growing evidence that reproductive aging is linked to overall health in men, but this review mainly focuses on pathophysiological consequences of old age in men, such as low sperm count and diminished sperm genetic integrity, with an emphasis on mechanisms underlying reproductive aging. The steady decline of NAD levels observed in aging men represents one of the emerging concepts in that regard. Because it offers some mechanistic rationale explaining the effects of old age on the male reproductive system, some of the NAD-dependent functions in male reproduction are briefly outlined in this review. The overview also provides many questions that remain open about the basic science of male reproductive aging.
The Failure of Poseidon, ‘Averter of Disaster’ and the Mythical Geography of Isaiah 23:1–14
Authors: Scolnic Benjamin 
Published: March 2024

AbstractThe nostos, the return home in Greek mythology, is most often a journey over the sea, and it is the god Poseidon who rules the sea, both ensuring the safe passage of fishermen and sailors and causing disasters to individuals like Ajax son of Oileus, sometimes through obstacles like his daughter Charybdis. Most famously, he uses his power to hinder the nostos of Odysseus, all the while knowing he cannot prevent him from reaching home. This example illustrates how a god who may once have been the most powerful deity can no longer control ultimate results. As his power declines over the centuries, that of Zeus increases.It is also by sea that we see the ships in Isaiah 23, attempting to return to their homes in Sidon and Tyre on the eastern Mediterranean coast. In this Biblical passage from the eighth century BCE, the ships wail when they see that their seaport homes have been destroyed; there are no homes to which they can return. The great god of the Sea and the epichoric gods have failed to protect the cities which are considered their progeny. The Israelite prophet mocks their powerlessness and celebrates the power of his One God. There is no nostos, no homecoming for ships because they no longer have homes. Just as Poseidon could not prevent Odysseus from his nostos, the so-called Averter of Disaster has not prevented the disaster that has befallen his children.
Background Seismic Noise Levels among the Caribbean Network and the Role of Station Proximity to Coastline

Abstract
The amplitude and frequency content of background seismic noise is highly variable with geographic location. Understanding the characteristics and behavior of background seismic noise as a function of location can inform approaches to improve network performance and in turn increase earthquake detection capabilities. Here, we calculate power spectral density estimates in one-hour windows for over 15 yr of vertical-component data from the nine-station Caribbean network (CU) and look at background noise within the 0.05–300 s period range. We describe the most visually apparent features observed at the CU stations. One of the most prominent features occurs in the 0.75–3 s band for which power levels are systematically elevated and decay as a function of proximity to the coastline. Further examination of this band on 1679 contiguous USArray Transportable Array stations reveals the same relationship. Such a relationship with coastal distance is not observed in the 4–8 s range more typical of globally observed secondary microseisms. A simple surface-wave amplitude decay model fits the observed decay well with geometric spreading as the most important factor for stations near the coast (&lt;∼50 km). The model indicates that power levels are strongly influenced by proximity to coastline at 0.75–3 s. This may be because power from nearshore wave action at 0.75–3 s overwhelms more distant and spatially distributed secondary microseism generation. Application of this basic model indicates that a power reduction of ∼25 dB can be achieved by simply installing the seismometer 25 km away from the coastline. This finding may help to inform future site locations and array design thereby improving network performance and data quality, and subsequently earthquake detection capabilities.

: Rituximab is a humanized chimeric anti-CD20 monoclonal antibody that quickly lowers blood serum levels of anti-desmoglein autoantibodies, causing pemphigus lesions to heal. To evaluate the efficacy of Rituximab in treating pemphigus vulgaris. : We identified and included 14 patients (3 males and 11 females), in the age group of 14 years to 67 years, of severe pemphigus vulgaris from 2016 to 2022 treated at our institution with rituximab infusion in our retrospective case study. Baseline anti-desmoglein antibodies 1 and 3 levels were elevated in all the patients. 12 of these patients received rituximab infusion as first-line treatment. 11(out of 14) patients received two doses of rituximab (1 gram in each) as intravenous infusions, as per the rheumatoid arthritis protocol; whereas, 3 (out of 14) received a single dose of intravenous rituximab infusion (1 gram). These patients were kept on maintenance dose of prednisolone/ mycophenolate mofetil post rituximab infusion. : 14 patients of pemphigus vulgaris were enrolled in the study. The follow-up period ranged from 2 months to 6 years. All 14 patients responded well to therapy. No serious adverse events were observed. 10 (71.4%) of the 14 patients exhibited complete remission; whereas, 4 (28.6%) showed partial remission. Those with partial remission experienced relapse but the subsequent episode was less severe than the first episode. However, 2 patients who were non-responders to high doses of systemic steroids expired. : For treating patients with pemphigus vulgaris, rituximab infusion was found to be safe and effective. Hence, it should be considered as first-line for management of pemphigus vulgaris.

Background: Pseudorabies virus (PRV), responsible for pseudorabies, is one of the most important pathogen in swine industry. PRV infection suppresses interferon-β (IFN-β) and tumor necrosis factor-α (TNF-α) expression, which consequently results in an immune escape in the host. Methods: In this study, distribution of peripheral blood T and B cell sub-populations was analyzed by flow cytometry after infecting mice with 1×105 TCID50 PRV. Result: We found that the levels of CD3+ T, CD4+ T and CD8+ T lymphocyte in infection group were significantly decreased at 24 hpi (p less than 0.01) and remained at a low level until 72 hpi compared to the control group. Interestingly, the levels of CD19+ T lymphocyte were significantly lower after 24 hpi (p less than 0.01) and lasted until 48 hpi, then increased sharply and then dropped at 96 hpi. Collectively, these results indicated that PRV infection could play a negative role in adaptive immunity in mice by decreasing the levels of B and T lymphocytes.

Aim: The aim of this study is to examine the satisfaction levels of individuals using public recreation areas and their expectations from these areas.
Methods: A total of 350 individuals aged between 18 and 61 participated in the study voluntarily . The data in the study were obtained by applying the demographic information form prepared by the researcher and the satisfaction scale of the recreation services of the municipalities developed by Çoban (2002). The obtained data were analyzed in SPSS program.
Results: As a result of the analysis; participants generally; are male (57.7%), the age range is concentrated between 35-50 (36.3%), the participants generally have a university education (58.9%), the majority (54.3%) do not do sports regularly, and the services of the municipalities are not sufficient. It was determined that those who did not find it were in the majority (57.1%). It was determined that the average score of the participants' satisfaction scale was 3.5±0.6. While there was no statistically significant difference in this score when the gender, age range, and working years of the participants were taken into account, it was determined that there were significant differences when the education level and levels of finding the services were sufficient.
Conclusion: Based on these findings; It was determined that the participants did not find the recreation areas provided by the municipalities sufficient. According to this, it can be said that this situation can change by arranging the recreation areas in accordance with the purpose and increasing the number of them.
