Bir Kurşun Madeninde Titreşim ve Gürültü Maruziyetlerinin Araştırılması
Bu çalışma Marmara Bölgesi’nde bir kurşun madeninde fiziksel risk etmenlerinden olan gürültü ve titreşimin iş sağlığı ve güvenliği yönünden uygunluğunu belirlemek amacıyla 2021 ve 2023 yıllarında gerçekleştirilmiştir. Kurşun madeninde, A Galeri-si’nde gürültü, iç ortam gürültü ölçümleri ve titreşim ölçümleri alınmış, elde edilen sonuçlar ilgili standartlar ile karşılaştırılmış ve çeşitli tablo ve grafikler yardımı ile yorumlanmıştır. Kişisel gürültü ölçüm sonuçları 2023 yılında 2021 yılana göre oransal olarak azalmış fakat standartların üzerinde olduğu saptanmıştır. İç ortam gürültü düzeyi de 2021’den 2023’e artış göstermiş ve 2023 yılında standartların üze-rine çıkmıştır. Titreşim ölçüm sonuçları incelendiğinde 2021 yılına göre 2023 yılında artış olduğu görülmüştür. Hem gürültü hem de titreşim değerlerini standartların altına düşürülmesi çalışanlarda ciddi sağlık ve güvenlik risklerini en aza indirmek için çok önemli olup, gerekli kontroller, eğitimler, çalışma yöntem değişimleri, uygun koru-yucu donanımlar ve yeni teçhizatlar ile gerekli önlemleri almak mümkündür.

Barrow holographic dark energy models in Lyra and general relativity theories
This study investigates the Barrow holographic dark energy (BHDE) matter distribution in the Bianchi I universe model in Lyra and General Relativity Theories. To this end, it obtains exact solutions by Hubble parameter, conservation equation, and BHDE energy density equation and supports them with graphics. The results show that the solutions are in harmony with the functioning of the universe and the nature of dark energy. It finally discusses the need for further research.

Investigation of dark energy scenarios in f(Q) gravitation theory
In order to solve the mystery of the accelerating and expanding universe model first, various dark energy candidates, such as Quintessence, Tachyon, k-essence, Phantom and DBI-essence, were investigated in detail in the [ ] modified symmetric teleparallel gravitation theory for homogeneous and isotropic FRLW universe model. The [ ] model is used to obtain solutions in [ ] theory. Also, the physical behaviors of some cosmological parameters such as pressure and density were studied. Dark energy candidates were analyzed for different values of n with various graphs.

FLRW cosmological models with quark and strange quark matters in f(R,T) gravity
In this paper, we have studied the magnetized quark matter (QM) and strange quark matter (SQM) distributions in the presence of $ f(R,T)$ gravity in the background of Friedmann--Lema\^itre--Robertson--Walker (FLRW) metric. To get exact solutions of modified field equations we have used $f(R,T) = R + 2 f(T)$ model given by Harko et al. with two different parametrization of geometrical parameters \textit{i.e.} the parametrization of the deceleration parameter $ q $, and the scale factor $ a $ in hybrid expansion form. Also, we have obtained Einstein Static Universe (ESU) solutions for QM and SQM distributions in $f(R,T)$ gravity and General Relativity (GR). All models in $f(R,T)$ gravity and GR for FRW and ESU Universes with QM also SQM distributions, we get zero magnetic field. These results agree with the solutions of Akta{\c{s} and Ayg\"un in $f(R,T)$ gravity. However, we have also discussed the physical consequences of our obtained models.Open AccessFLRW cosmological models with quark and strange quark matters in f(R,T) gravity

The exact solutions of the field equations are obtained under bilinear and special form of time varying deceleration parameter (DP). Firstly we have considered two specific form of bilinear DP with a single parameter of the form: $q=\frac{\alpha(1-t)}{1+t}$ and $q=-\frac{\alpha t}{1+t}$, which leads to a function with constant or linear nature with respect to the choice of constant $\alpha$. Second one is the special form of the DP as $q=-1+\frac{\beta}{1+a^{\beta}}$. From obtained results, we could say that in the early universe the magnetic flux has more effects and it gradually reducing its effects in later. For $t\rightarrow \infty$, we get $p\rightarrow -B_c$ and $\rho\rightarrow B_c$. So the strange quark matter along with magnetic epoch gives an idea of accelerated expansion of the universe as per the observations of the type Ia Supernovae.Open AccessMagnetized strange quark matter in $f(R,T)$ gravity with bilinear and special form of time varying deceleration parameterIn this paper, we have studied homogeneous and anisotropic, locally rotationally symmetric (LRS) Bianchi type-I universe model with magnetized strange quark matter (MSQM) distribution and cosmological constant $\Lambda$ in $f(R,T)$ gravity.

- Open AccessMagnetized strange quark model with Big Rip singularity in $f(R,T)$ gravityLRS (Locally Rotationally symmetric) Bianchi type-I magnetized strange quark matter cosmological model have been studied based on $f(R,T)$ gravity. The exact solutions of the field equations are derived with linearly time varying deceleration parameter which is consistent with observational data (from SNIa, BAO and CMB) of standard cosmology. It is observed that the model start with big bang and ends with a Big Rip. The transition of deceleration parameter from decelerating phase to accelerating phase with respect to redshift obtained in our model fits with the recent observational data obtained by Farook et al. in 2017. The well known Hubble parameter $H(z)$ and distance modulus $\mu(z)$ are discussed with redshift.Open AccessMagnetized strange quark model with Big Rip singularity in $f(R,T)$ gravityLRS (Locally Rotationally symmetric) Bianchi type-I magnetized strange quark matter cosmological model have been studied based on $f(R,T)$ gravity.
