This study aims to explore predictors of performance ascertaining the optimal body composition for world-level arm wrestlers in a competitive environment. Athletes underwent body composition assessments and their final competition classifications were noted. Athletes had a pairwise comparison percentile groups for relative fat mass (FM%), scattered by country, fat-free mass (FFM%) clustered by final classification, and comparison of the final classifications, grouped by country. A total of 220 elite, male competitors from 33 countries showed a mixed classification by country for FM% percentiles (p = .089) with values ranging from the 10th percentile (FM = 7.1%) to above the 90th percentile (FM = 16.1%). Extreme values (FM = 4.5%) and country of origin did not predict the classification of the athletes, although the athletes´ ranking <75th did suggest a tendency towards classification (FFM% = 27.3%). Thus, world-level arm wrestlers revealed nutritional issues concerning values for body composition components in a competition environment.

O artigo científico proposto examina as diretrizes ambientais em vigor no Brasil em relação à minimização dos impactos ambientais da agroindústria. O direito ambiental tornou-se um campo separado no Brasil após a promulgação da Constituição Federal de 1988, que estabeleceu que o Estado e a sociedade devem cuidar do meio ambiente. A agroindústria é uma atividade econômica que é regulamentada por normas ambientais, incluindo a utilização de recursos hídricos, a gestão de resíduos sólidos, a preservação da biodiversidade e a responsabilidade por danos ambientais. A agroindústria envolve o tratamento, modificação, acondicionamento e embalagem de produtos agrícolas. Esta atividade está alinhada com os princípios de desenvolvimento sustentável. O estudo consiste em uma revisão de literatura das normas ambientais brasileiras, caracterizada como uma pesquisa qualitativa que emprega o método dedutivo, partindo de premissas gerais (normas) para casos específicos. Utiliza-se de pesquisa documental (legislação internacional/nacional e dados secundários) e bibliográfica (doutrina, monografias, dissertações e artigos científicos nacional/internacional). Assim, notou-se que A legislação ambiental brasileira é complexa e abrangente, mas reflete o esforço contínuo do país para equilibrar as demandas econômicas com a preservação ambiental, reconhecendo a importância da agroindústria para o desenvolvimento do país e reconhecendo a necessidade de práticas sustentáveis e responsáveis no setor.

Atualmente, a lei ambiental do Brasil tem vários níveis, incluindo leis federais, decretos, resoluções e regulamentos. Tal legislação é revisada e atualizada para atender às novas realidades e desafios gerados pela dinâmica da relação entre atividades humanas e o meio ambiente, principalmente na agroindústria. No entanto, existem algumas lacunas que impedem que as políticas públicas destinadas à conservação dos recursos naturais e à redução dos efeitos prejudiciais que a atividade agroindustrial tem sobre o meio ambiente. Não obstante, o objetivo deste estudo é examinar as lacunas legais na legislação ambiental agroindustrial do Brasil e sugerir soluções para os problemas que surgem nesses dispositivos legais. Portanto, o estudo atualmente é uma revisão da literatura sobre as lacunas nas normas ambientais brasileiras. Por outro lado, este estudo é uma investigação que emprega o método dedutivo, começando com pressupostos gerais (normas) e passando por casos concretos (casos específicos), e uma abordagem qualitativa. O objetivo da pesquisa é determinar as discrepâncias legais e seus principais efeitos, utilizando técnicas de pesquisa documental (legislação e dados secundários internacionais e nacionais) e bibliográfica (doutrina, monografias, dissertações e artigos científicos internacional/nacional). Com efeito, uma reforma completa e integrada das normativas ambientais é a única maneira de encorajar a transição do setor agroindustrial brasileiro para um modelo verdadeiramente sustentável que possa conciliar a produtividade com a conservação dos recursos naturais e reduzir os impactos ambientais.

Contemporary directions in the therapy of sensory hearing loss
Authors: Rzepakowska Anna , Borowy Aleksandra , Siedlecki Eryk , Wolszczak Marta , Radomska Katarzyna
Published: August 2024

Introduction: More than 5% of the world’s population experience hearing impairment. The most common form is presbycusis (age-related hearing loss; ARHL). It affects almost one in three people over the age of 65. The hair cells of the cochlea play an important role in the process of sound registration. Genetic mutations, aging and environmental factors can cause damage that contributes to the hearing loss.Methods and results: The currently explored research directions include drug treatments, gene therapies, and stem cell therapies. To date, no significant differences in the therapeutic effect depending on the route of corticosteroid administration have been demonstrated in patients with moderate to severe hearing loss. New dexamethasone-containing hydrogel formulations, as well as lipid formulations, thermosensitive polymers, and nanoparticles, have been developed to achieve high drug concentrations in the inner ear structures. Otoprotective effects of antioxidants or substances that modify the toxic effects of e.g. cisplatin, are also being studied. Attempts at auditory cells’ regeneration seem promising in hearing loss research. Substances that regulate the central mechanisms of the Notch and Wnt pathways are being explored to this end. The genetic determinants of presbycusis suggest that interference at the level of specific genes may be a promising option for the treatment of this condition. With the CRISPR/Cas9 technology, the functions of inner ear genes can be effectively studied by disrupting normal gene alleles. The CRISPR/Cas9 complexes developed to target specific genes are delivered using cationic lipids, proteins, and viral vectors. They are then transported through the round window membrane by diffusion, without the need to surgically disrupt the inner ear. The potential of using antisense oligonucleotides to treat hereditary deafness caused by hair cell degeneration has also been established. Another research direction is related to stem cells being used for the development of in vitro 3D models of the human inner ear. Studies are also pursued to identify the mechanisms underlying the formation of cochlear organoids from pluripotent cells as well as determine the critical time points and events for cochlear sensory epithelial development and targeted hair cell differentiation.Conclusions: In summary, significant progress has been made over the past decade in the search for novel therapies for sensory hearing loss. This line of research remains an ambitious and important area for further exploration.

Published: August 2024

The waters of Peropaare part of the water area in South Kaledupa District, Wakatobi Regency, Southeast Sulawesi. This research is needed to determine the components of hydro-oceanography, namely tides, bathymetry, currents and waves. Tidal conditions were obtained through analysis using the Admiralty Method from tidal data for 15 days, resulting in a semidiurnal mixed tide prevalling type with the highest tide of 3.16 m and the lowest low tide of -0.29 m. The bathymetry measurement method uses hydroacoustic principles via a single beam echosounder instrument, obtaining a depth of 10 m closest to the coastline at a distance of 70 m in the northwest part of the research area and at a distance of 20 m in the southeastern part of the research area. Conditions for the movement of ocean currents and waves are carried out using a hydrodynamic model approach. Based on the results of the ocean current model, the direction of the current tends to follow the coastline with the dominant flow direction moving east and north at high tide and south and west at low tide, with a current speed range of 0.075-0.13 m/s at the highest tide and 0.04 -0.1 m/s at lowest ebb. The wave heights that occur in the research area range from less than 0.75 m to 2.5 m.

Study Of The Potential Effect Of Bovine Colostrum On Some Physiological Parameters In Male Rats Receiving Etoposide Therapy
Authors: Alsudani Arjwan A
Published: August 2024

Both radiation and chemotherapy are vital treatments for cancer patients, but they have some disadvantages, for example, a greater chance of adverse effects, limited accessibility, and the non-selective character of chemotherapy drugs. The current study's objective was to look at the function of different concentrations of bovine colostrum in enhancing and activating the immune system, reducing immune suppression, and mitigating the effects of the chemotherapy Etoposide on some physiological and immune parameters in male albino rats. Eight groups, consisting of the control group (C) and several treatment groups (T1-T7), were created from forty adult male rats. After a 4-week experimental period, the animals were anesthetized, and blood was directly drawn from the heart for necessary tests. The tests included blood tests (Red blood cell count, Hemoglobin concentration, packed cell volume PCV), immune parameters (C-reactive protein, Interleukin 12, platelet count), and tests for some liver and kidney parameters (Urea, Creatinine, ALT, AST, ALP). Additionally, antioxidant and oxidant tests (MDA, SOD, CAT, GLU) were conducted. According to the findings, the normal values of the parameters that were tested significantly changed when etoposide was used in group T1. However, the use of colostrum at different concentrations with Etoposide for groups T2, T3, and T4 resulted in improvement in the values of the measured parameters, approaching the control group in some cases, especially in group T4 exposed to a dose of colostrum and Etoposide of 1500 IU/kg. On the other hand, groups treated with colostrum alone (T5, T6, T7) indicated results similar to the group under control, and no unfavourable side effects were noticed. In conclusion, the use of chemotherapy Etoposide has negative effects on some physiological and hematological parameters and affects the vital functions of treated rats. Conversely, the study demonstrates the positive role of using colostrum at various concentrations in enhancing immunity and preventing or reducing oxidative stress and inflammation resulting from Etoposide on the vital functions of male albino rats.
Effects of cowpea (Vigna unguiculata (L.) Walp.) as a fishmeal replacer in diet on growth performance of catfish Clarias gariepinus (Burchell, 1822) reared in tanks
Authors: Badji Luc Bonaventure , Ndao Aliou , Gueye Moussa
Published: August 2024

The aim of this study was to test the substitution of fish meal by cowpea meal Vigna unguiculata in order to improving access for local fish farms to a high-performance feed at low cost. The experimental system consisted of two tanks, each containing 30 Clarias gariepinus individuals. In tank T1, the fish were fed with imported fishmeal feed, while in tank T2, they were fed with feed made locally from cowpea meal. During the three-week experiment, mean temperature in the tanks varied between 25±.27 and 26±19, and pH between 7±10 and 8±.09. These values were close to the optimum growth conditions for C. gariepinus fry. Growth data were obtained by evaluating various growth parameters. Data on average length and weight gains showed that the T1 feed had the best results with an increase of 5.83cm and 13.69g, compared with 2.58 cm and 7.02 g for the T2 diet. In terms of feed conversion ratio, the fishmeal-based feed had the lowest value (1.4 compared with 2.32 for local food), which also means that it's the diet most likely to promote weight gain in fish. Similarly, the T1 diet also showed the best Specific Growth Rate (1.61% / day) compared with the T2 diet (0.76% / day). These results suggested that cowpea meal could be used as a feed component in clarias farming, but appears less efficient when used to replace fishmeal entirely.

Authors: Atani Shahabaddin Ebrahimi
Published: August 2024

Since ideals in rings and semirings are closely related, two-sided $k$-ideals occur frequently in semiring theory. Let $R$ be a commutative semiring. For an ideal of $R$, the notion of $k$-weakly primary ideals is defined. It is shown that this notion inherits most of the essential properties of the weakly primary ideals of a commutative ring (see [1], [4]). For example, it is proved that a $k$-weakly primary ideal $A$ of $R$, that is not primary, satisfies $A^{2} = 0$ and rad ($A$) = rad (0). Also, it is shown that an intersection of a family of $k$-weakly primary ideals, that are not primary, is $k$-weakly primary.

On a Functional Equation Related to the Determinant of Symmetric Two-By-Two Matrices
Authors: Houston Kelly B. , Sahoo P. K.
Published: August 2024

The present work aims to find the solutions $f,g,h, \ell , m : \mathbb{R}^2 \to \mathbb{R}$ of the functional equation $f( ux - vy , \, uy - vx ) = g(x, y ) + h(u, v) + \ell (x , y ) \, m(u , v)$ for all $x, y, u, v \in \mathbb{R}$ without any regularity assumptions on the unknown functions. This equation is a generalization of a functional equation which arises from the characterization of the determinant of symmetric matrices.

On Foci and Asymptotes of Conics in the Isotropic Plane
Authors: Beban-Brkić J. , Šimić M. , Volenec V.
Published: August 2024

The paper shows that every conic with foci in the isotropic plane can be represented by the equation of the form $y^2=\epsilon x^2+x$, where $\epsilon \in \{-1, 0, 1\}$ for an ellipse, a parabola and a hyperbola with foci respectively. Using this equation some important properties of the foci are proved. According to duality the properties of asymptotes of the hyperbola in the isotropic plane are valid as well.

Properties of Nehari Disks
Authors: Miller-Van Wieren Leila
Published: August 2024

Let $D$ be a simply connected plane domain and let $B$ be the unit disk. The inner radius of $D$, $\sigma (D)$ is defined by $\sigma (D) = \sup \{a:a \geq 0,||S_f||_{D} \leq a$ implies $f$ is univalent in $D$ . Here $S_f$ is the Schwarzian derivative of $f$, $ \rho_{D}$ the hyperbolic density on $D$ and $ || S_{f} ||_{D} = \sup_{z \in D} |S_{f} (z)|\rho_{D}^{-2} (z) $. Domains for which the value of $ \sigma (D)$ is known include disks, angular sectors and regular polygons as well as certain classes of rectangles and equiangular hexagons.
When the inner radius for the above-mentioned domains, except non convex angular sectors, is computed it is seen that $ \sigma (D) = 2- || S_h ||_{B}$, where $ h:B \longrightarrow D $ is the Riemann mapping and $B$ the unit disk, a fact that yields a convenient method for computing $\sigma(D)$. We introduce the name Nehari disks for domains with the above property.
In this paper we generalize some results by Gehring, Pommerenke, Ahlfors and Minda that were proved in the unit disk, to analogous results for Nehari disks.

Some Results on the Composition of Distributions
Authors: Ege Inci
Published: August 2024

Let $F$ be a distribution, $f$ be a locally summable function and $F_{n} = (F * \delta_{n})(x)$, where $\delta_{n}(x)$ is a certain sequence converging to the Dirac delta-function $\delta(x)$. The distribution $F(f)$ is defined as the neutrix limit of the sequence $\{ F_n(f) \}$, provided its limit $h$ exists in the sense that $$ \Nn \int_{-\infty}^{\infty} F_{n}(f(x))\varphi (x) dx = \la h(x) , \varphi (x) \ra $$ for all test functions $\varphi(x)$ in ${\mathcal D}(a,b)$. The composition of the distributions $x_{-}^{-s}\ln x_{-}$ and $x_{+}^{r}$ is evaluated for $r=0,1, \ldots$ and the composition of the distributions $x_{-}^{-s}\ln^{m} x_{-}$ and $H(x)$ is evaluated for $s,m=1,2,\ldots\,$.

Global Dynamics of Certain Non-symmetric Second Order Difference Equation With Quadratic Term
Authors: Garić-Demirović M. , Hrustić S. , Moranjkić S.
Published: August 2024

We investigate global dynamics of the equation\begin{equation*}x_{n+1}=\frac{x_{n-1}+F}{ax_{n}^2+f},\text{ \ }n=0,1,2,...,\end{equation*}where the parameters $a,F$ and $f$ are positive numbers and the initial conditions $x_{-1},x_{0}$ are arbitrary nonnegative numbers such that $x_{-1}+x_{0}>0$. The existence and local stability of the unique positive equilibrium are analyzed algebraically. We characterize the global dynamics of this equation with the basins of attraction of its equilibrium point and periodic solutions.
An Equivalent Form of the Prime Number Theorem
Authors: Reddy G. Sudhaamsh Mohan , Rau S. Srinivas , Uma B.
Published: August 2024

A simple proof is given that $\sum\limits_{n}\frac{\mu(n) d(n)}{n}=0$ using the Prime Number Theorem. It is shown that this is equivalent to the estimate $\sum\limits_{n\leq x}\mu(n)d(n)=\circ(x)$ and to the Prime Number Theorem.

Authors: Çınar Selin , Demirci Kamil
Published: August 2024

In the present paper, we extend the Korovkin type approximation theorem via $%\mu -$statistical $\mathcal{A}$-summation process onto the double sequences of positive linear operators in a modular space. We apply our new result to bivariate Mellin-type operators in Orlicz spaces. Then we discuss the reduced results which are obtained by special choices and the matrix sequences.
On the LPA model with $\mu_a$ = 1
Authors: Jamieson William T. , Merino Orlando
Published: August 2024

In this article we establish conditions for the local stability of the positive fixed point for the structured population model of Dennis, Desharnais, Cushing, and Costantino (or LPA model) where no adults survive longer than a single time step and when there is a specific one-parameter bifurcation. Also, we study local and global behavior of orbits for which at least one component is equal to zero, and establish conditions for the existence of a curve contained in the union of the coordinate planes which is invariant for the map associated with the model.

Slant Lightlike Submanifolds of Semi-Riemannian Product Manifolds
Authors: Kumar Tejinder , Kumar Sangeet , Kumar Pankaj
Published: August 2024

The aim of the present paper is to investigate geometric characteristics of slant lightlike submanifolds of semi-Riemannian product manifolds. We obtain characterization theorems for the existence of slant lightlike submanifolds of semi-Riemannian product manifolds. We also find a necessary and sufficient condition enabling the induced connection on slant lightlike submanifolds of semi-Riemannian product manifolds to be a metric connection. Then, we establish some results for the integrability of distributions associated with this class of lightlike submanifolds. Consequently, we investigate totally umbilical slant lightlike submanifolds of semi-Riemannian product manifolds. In particular, we prove that every totally umbilical slant lightlike submanifold of a semi-Riemannian product manifold is always totally geodesic.
