Published: August 2024

Sektor property dan real estate memiliki peran penting bagi ekonomi dan pembangunan Indonesia. Peranan sektor tersebut dapat digunakan untuk melihat peningkatan ekonomi negara. Dalam perkembangan dunia sekarang ini dapat kita lihat maju atau berkembangnya suatu negara berdasarkan bangunan yang terdapat di kota-kota besar dalam suatu negara jika bangunannya modern dan diisi dengan bangunan yang modern dan banyak gedung menjulang tinggi maka dapat kita ambil kesimpulan bahwa negara itu merupakan negara yang maju dan berkembang. Tujuan setiap perusahaan adalah menghasilkan tingkat laba yang tinggi dengan memanfaatkan ketersediaan sumber daya baik melalui modal sendiri maupun menggunakan hutang guna meningkatkan profitabiltas yang telah direncanakan dan diharapkan oleh perusahaan, akan tetapi belum tentu dengan adanya pertambahan modal ataupun hutang akan meningkatkan laba perusahaan, bisa jadi kebalikannya atau malah tidak berpengaruh sama sekali. Penelitian ini bertujuan untuk mengertahui dan menganalisis pengaruh hutang dan modal terhadap profitabilitas perusahaan property dan real estate yang terdaftar di Bursa Efek Indonesia. Indikator untuk mengukur rasio profitabilitas menggunakan Net Profit Margin (NPM), Hutang menggunakan Debt to Equity Ratio (DER) sedangkan Modal menggunakan Proprietary Ratio (PR). Metode Penelitian penelitian ini adalah kuantitatif. Populasi dalam penelitian ini adalah 79 perusahaan dan diteliti selama 4 tahun jadi total pupulasinya adalah 316, Sampel yang digunakan 10 perusahaan selama 4 tahun mulai dari tahun 2018 sampai tahun 2021, sampling yang digunakan adalan Purposive sampling. Dari hasil penelitian dapat ditarik kesimpulan berupa hutang memiliki pengaruh negatif terhadap profitabilitas yang artinya semakin banyak hutang akan mengurangi profitabiltas, kemudian modal memiliki pengaruh positif dengan profitabilitas yang artinya semakin banyak modal maka akan semakin meningkatkan profitabilitas. Serta Berdasarkan Uji F diketahui bahwa secara simultan hutang dan modal memiliki pengaruh secara signifikan terhadap profitabilitas.

Authors: Garima Singh  , Pammi Gauba  , Garima Mathur  
Published: August 2024

Cellulose is a naturally occurring polysaccharide that is produced by both plants and micro-organisms. It is one of the most prevalent organic substances in the natural world. Compared to plant cellulose, bacterial cellulose (BC) exhibits superior physicochemical properties such as high purity, crystallinity, biocompatibility, biodegradability, and water holding ability, making it an excellent choice of material for various industrial and biomedical applications. However, large scale production and utilization of BC suffers from limitations related to its low yield and high production cost. In this research, an attempt was made to investigate the effects of different carbon sources on the bacterial cell growth kinetics, BC yield and physicochemical characteristics of Acetobacter aceti MTCC 2623. The results showed variations in growth kinetics and BC yields under different conditions. Among the selected carbon sources, Hestrin and Schramm (HS) medium supplemented with glucose gave highest BC yield of 2.89±0.18 g/L, whereas glycine resulted in the lowest BC yield, which was 0.089±0.17 g/L. FTIR spectral analysis showed no significant variations in the characteristic vibrational bands for BC prepared using different carbon sources. DSC results indicated the superior thermal stability of BC samples over commercial cellulose. Our findings suggest that BC production by A. aceti using glucose as C-source in HS media may be scaled up for enhanced production of BC. The improved physicochemical characteristics of BC compared to commercial cellulose point to the importance of BC as a potential candidate for several biomedical and industrial applications.

A toxoplasmose é uma zoonose cosmopolita causada pelo protozoário Toxoplasma gondii. Embora os felinos sejam frequentemente associados à doença, as principais vias de infecção em seres humanos são por meio da ingestão de alimentos ou água contaminados com oocistos esporulados do protozoário, e a forma de transmissão de maior relevância é a vertical, quando aconteceda mãe para feto durante a gestação, pois pode causar aborto e diversos alterações neurológicas no recém nascido, por isso a importância de educação da população sobre quais as principais formas de transmissão da doença e que o gato doméstico não transmite a infecção ao ser humano pelo contato direto. Assim, visto que a educação em saúde desempenha um papel essencial na prevenção de doenças, o presente trabalho tem o objetivo de relatar as experiências do projeto de extensão “Abrace seu gato: acariciar o animal não transmite a toxoplasmose”. O projeto vinculado à Pró-reitoria de Extensão (PROEX) da Universidade Federal de Sergipe – Campus Sertão contou com a participação de discentes da graduação, pós-graduação e docentes da graduação em medicina veterinária. Foram desenvolvidas ações educativas com o intuito de desmistificar a forma de transmissão da doença através do contato direto com o gato e instruir a população sobre os cuidados necessários para evitar a infecção. Ao todo foram realizadas quatro ações na Semana Acadêmica da UFSSER e nas campanhas de castração e de vacinação antirrábica da Prefeitura de Nossa Senhora da Glória. Nessas ações, o público-alvo era instruído sobre as principais formas de transmissão da doença e as medidas de prevenção e controle, através da realização de atividades lúdicas, como jogos de perguntas e repostas e quebra-cabeças, além disso, houve a entrega de folders com informações sobre o tema. O projeto contribuiu de forma ativa na orientação e na sensibilização do público alvo, também para o entendimento dos discentes em relação aos desafios a serem enfrentados como futuros profissionais da área da saúde.

Measurability – Preserving Weakly Mixing Transformations
Authors: Fatkić Huse 
Published: August 2024

In this paper we investigate measure-theoretic properties of the class of all weakly mixing transformations on a finite measure space which preserve measurability. The main result in this paper is the following theorem: If $\phi $ is a weakly mixing transformation on a finite measure space $( S, \mathcal A , \mu )$ with the property that $\phi (\mathcal A ) \subseteq \mathcal A ,$ then for every $A, B $ in $\mathcal A$ there is a subset $J(A,B)$ of the set of non-negative integers of density zero such that $\lim _{m \to \infty ,m \notin J(A,B)} \mu (A \cap \phi ^m(B)) = (\mu (A) / \mu (S))\lim _{n \to \infty } \mu \,(\phi^n(B)).$ Furthermore, we show that for most useful measure spaces we can strengthen the preceding statement to obtain a set of density zero that works for all pairs of measurable sets $A$ and $ B.$ As corollaries we obtain a number of inclusion theorems. The results presented here extend the well-known classical results (for invertible weakly mixing transformations), results of R. E. Rice [17] (for strongly mixing), a result of C. Sempi [19] (for weakly mixing) and previous results of the author [8, 10] (for weakly mixing and ergodicity).

Authors: Udovičić Zlatko 
Published: August 2024

By using the quadratic interpolating spline a new class of the quadrature rules was obtained. Those formulas are modifications of the well known trapezoidal rule. The basic characteristic of those formulas is a free parameter. With appropriate choice of that parameter, accuracy of the trapezoidal rule can be improved up to $O(h^4).$ Besides this, by using this nonstandard techniques some well known quadrature rules were also obtained.

We also consider the case of an unbounded domain.

Two Results on the Commutative Product of Distributions and Functions
Authors: Fisher Brian 
Published: August 2024

Let $f$ and $g$ be distributions and let $f_n=(f*\delta_n x)$ and $g_n =(g*\delta _n)(x)$, where $\delta _n(x)$ is a certain sequence converging to the Dirac delta-function. The product $f .g$ of $f$ and $g$ is defined to be the limit of the sequence $\{f_ng_n\}$, provided its limit $h$ exists in the sense that $$\lim _{n \to \infty} \langle f_n (x) g_n (x),\vphi (x) \rangle =\langle h(x), \vphi (x) \rangle $$ for all functions $\vphi$ in ${\mathcal D}.$ It is proved that \begin{align*}(\sgn x|x| ^{-r} \ln ^p |x|). ( |x| ^\mu \ln^q|x|)&=\sgn x |x| ^{-r +\mu } \ln ^{p+q}|x| ,\\(|x| ^{-r} \ln ^p |x|). (\sgn x |x| ^\mu \ln ^q|x| ) &=\sgn x |x| ^{-r +\mu } \ln ^{p+q}|x|\end{align*}for $-2<-r+\mu< -1,$ $r=1,2, \ldots$ and $p,q =0,1,2. \ldots .$

Sheaves of Paragraded Rings
Authors: Ilić-Georgijević Emil , Vuković Mirjana 
Published: August 2024

In this paper we deal with sheaves of the category of paragraded rings with the same set of grades $\Delta,$ in short, the category of paragraded rings of type $\Delta,$ denoted by $R^P_\Delta.$ The definition of a sheaf of category $R^P_\Delta$ is the same as for any other category, but we are interested in the paragraded structure sheaf, as we named it here, and so, in some way we introduce the theory of paragraded structures into algebraic geometry. For this purpose we need to deal with homogeneous ideals, particularly, we need to introduce the prime spectrum of $R\in\mathrm{obj}(R^P_\Delta)$ and to analyze the localization of $R$.

Existence of Periodic Solutions for Totally Nonlinear Neutral Differential Equations With Variable Delay
Authors: Ardjouni Abdelouaheb , Djoudi Ahcéne 
Published: August 2024

We use a modification of Krasnoselskii's fixed point theorem introduced by T. A. Burton (see $\left[ 1\right] $ Theorem $3$) to show that the totally nonlinear neutral differential equation with variable delay\begin{multline*}x^{\prime }(t)=-a(t)x^{3}(t)+c(t)x^{\prime }(t-g(t))Q^{\prime}\left( x\left( t-g(t)\right) \right)\\ +G\left(t,x^{3}(t),x^{3}(t-g(t))\right) ,\end{multline*}has a periodic solution. We invert this equation to construct a sum of a compact map and a large contraction which is suitable for applying the modification of Krasnoselskii's theorem. The results of $\left[ 5\right]$ are generalized. Finally, an example is given to illustrate our result.
