CRIMES E MULHERES VÍTIMAS DE VIOLÊNCIA DOMÉSTICA
Authors: Nunes Evelyn Silva , Nascimento Maria Nívea Rocha Rodrigues do
Published: November 2024

Neste artigo será abordada a questão dos crimes cometidos contra mulheres vítimas de violência doméstica, com foco no impacto socioeconômico, cultural, psicológico e nas respostas do sistema jurídico brasileiro, com ênfase na Lei Maria da Penha. A pesquisa tem como objetivo avaliar a efetividade das políticas públicas e medidas protetivas diante dos desafios que as vítimas encontram no processo de denúncia e recuperação. A violência doméstica ainda representa uma das principais formas de violação dos direitos humanos, prejudicando a vida de mulheres de diferentes épocas e camadas sociais. A criação da Lei n.º 13.104/2015, que tipificou o feminicídio como crime autônomo, representou um marco na legislação brasileira. O feminicídio, caracterizado como o assassinato de uma mulher por razões de gênero, trouxe maior punição aos agressores e visibilidade ao problema. Contudo, a efetividade dessa lei depende de sua aplicação consistente e de uma mudança cultural que desafie as raízes do patriarcado. A legislação foi um avanço crucial, mas é necessário um esforço conjunto entre o Estado, o sistema de justiça e a sociedade para erradicar a violência de gênero de maneira eficaz.
AS IMPLICATURAS SÃO APLICÁVEIS AO DIREITO?
Authors: Abdo Bianca Maria Marinoni
Published: November 2024

O presente artigo dedica-se à análise da possibilidade de aplicação das implicaturas à interpretação da legislação. Em um primeiro momento, apresenta-se os conceitos de implicitura, implicatura convencional e implicatura conversacional, com as suas distinções essenciais. Depois, reconhece-se a existência de implicituras e implicaturas convencionais no direito, baseando-se em dispositivos legais vigentes. Com as implicaturas conversacionais, apresenta-se os problemas da definição dos integrantes de uma comunicação jurídica, da definição do seu contexto para fins de extração de implicaturas e, enfim, das dificuldades de enquadramento de implicaturas nas teorias atuais sobre interpretação e argumentação jurídica. Posteriormente, apresenta-se um exemplo de implicatura conversacional já em uso pelo direito processual civil, no que se refere à eficácia da coisa julgada sobre questão em benefício de terceiros. Por fim, conclui-se reconhecendo a ocorrência de implicituras, implicaturas convencionais e implicaturas conversacionais no Direito, mas pontuando a necessidade de definição de parâmetros para a utilização desses conceitos de forma adequada.

Published: November 2024

This research aims to determine and empirically test the influence of tax burden, intangible assets and foreign ownership on transfer pricing policies in energy sector companies listed on the Indonesia Stock Exchange (BEI) during the 2018 2022 period. This type of research is descriptive quantitative which uses secondary data sourced from the company's financial reports that have been published by the company on the Indonesia Stock Exchange (BEI). This research consisted of 84 companies and the number of samples used was 9 companies as research objects for five years. The data analysis technique for testing this hypothesis uses E-views 12 software. Panel data regression analysis is used as the mechanism in this research. The research results show that the tax burden has a significant effect on transfer pricing. Meanwhile, intangible assets and foreign ownership do not have a significant effect on transfer pricing. This is because companies can consider tax burdens, intangible assets and foreign ownership in transfer pricing policies
Mimimal graphs for completely independent spanning trees and completely independent spanning trees in complete t-partite graph
Authors: Hong Xia
Published: November 2024

Let $T_{1},T_{2},\dots,T_{k}$ be spanning trees of a graph $G$. For any two vertices$u,v$ of $G$, if the paths from $u$ to $v$ in these $k$ trees are pairwise openly disjoint, then we say that $T_{1},T_{2},\dots,T_{k}$ are completely independent spanning trees. In this paper, we give the definition of Minimal graph for $k$ completely independent spanning trees and we characterized all Minimal graphs for $k$ completely independent spanning trees. Finally, we obtain the number of completely independent spanning trees in complete $t(t\geq 2)$-partite graph $K_{n_{1},n_{2},\cdots,n_{t}}$, which is generalize the known result.
On characterization and recognition of proper tagged probe interval graphs
Authors: Paul Sanchita , Ghosh Shamik , Chakraboty Sourav , Sen Malay
Published: November 2024

Interval graphs were used in the study of the human genome project by the molecular biologist Benzer. Later on probe interval graphs were introduced by Zhang as a generalization of interval graphs for the study of cosmid contig mapping of DNA. Further research in this area required more useful and cost-effective tools. The concept of tagged probe interval graphs is motivated from this point of view. In this paper, we consider a natural subclass of it, namely, the class of proper tagged probe interval graphs. In this paper, we present a characterization theorem and a linear time recognition algorithm for proper tagged probe interval graphs. Also, we discuss the interrelations between the classes of proper tagged probe interval graphs and tagged probe interval graphs with probe interval graphs and probe proper interval graphs.
The Fractional Local Metric Dimension of Graphs
Authors: Javaid Imran , Benish Hira , Murtaza Muhammad
Published: November 2024

The fractional versions of graph-theoretic invariants multiply the range of applications in scheduling, assignment and operational research problems. For this interesting aspect of fractional graph theory, we introduce the fractional version of local metric dimension of graphs. The local resolving neighborhood $L(xy)$ of an edge $xy$ of a graph $G$ is the set of those vertices in $G$ which resolve the vertices $x$ and $y$. A function $f:V(G)\rightarrow[0, 1]$ is a local resolving function of $G$ if $f(L(xy))\geq1$ for all edges $xy$ in $G$. The minimum value of $f(V(G))$ among all local resolving functions $f$ of $G$ is the fractional local metric dimension of $G$. We study the properties and bounds of fractional local metric dimension of graphs and give some characterization results. We determine the fractional local metric dimension of strong and Cartesian product of graphs.

Authors: Andiyappan Shanmuga Vadivu , Muthusamy Appu
Published: November 2024

Let $K_n,$ $C_{n}$, and $P_{n}$ respectively denote the complete graph, cycle and path on $n$ vertices. Uniformly resolvable decomposition of $K_n$ is a decomposition of $K_n$ into subgraphs which can be partitioned into factors containing pairwise isomorphic subgraphs.
In this paper, we determine necessary and sufficient conditions for the existence of uniformly resolvable decomposition of $K_n$ into $P_4$ and $C_k,~ k\geq3.$
Multicolor compositions and conjugation of N-color compositions
Authors: Alanazi Abdulaziz , Archibald Margaret , Munagi Augustine
Published: November 2024

We introduce $n$-multicolor compositions which generalize the $n$-color compositions that Agarwal first defined twenty-two years ago.
A summand may bear a set of many integer-valued colors which it bounds from above.
We enumerate such multicolored compositions using generating functions. Then we isolate the conjugable class of multicolored compositions known as cracked compositions. A concise exposition of the conjugation of $n$-color compositions is presented in the classical tradition of Percy Alexander MacMahon (1854 - 1929). Our set of conjugable $n$-color compositions turn out to be considerably larger than previously known ones.
Some results about star-factors in graphs
Authors: Zhou Sizhong , Xu Yang , Sun Zhiren
Published: November 2024

For a set $\mathcal{S}$ of connected graphs, a subgraph $F$ of a graph $G$ is defined as an $\mathcal{S}$-factor of $G$ if $F$ satisfies that $V(F)=V(G)$ and every component of $F$ is isomorphic to an element of $\mathcal{S}$. If every component of $F$ is a star, then $F$ is said to be a star-factor. A star-factor with size at most $n$ may be written for a $\{K_{1,t}: 1\leq t\leq n\}$-factor. A graph $G$ is called a $\{K_{1,t}: 1\leq t\leq n\}$-factor deleted graph if $G-e$ has a $\{K_{1,t}: 1\leq t\leq n\}$-factor for every $e\in E(G)$. The sun toughness of a graph $G$ is denoted by $s(G)$ and defined as follows :$$ s(G)=\min \big\{\frac{|X|}{sun(G-X)}: X\subseteq V(G), \ sun(G-X)\geq2 \big\} $$ if $G$ is not a complete graph, and $s(G)=+\infty$ if $G$ is a complete graph, where $sun(G-X)$ denotes the number of sun components of $G-X$. In this paper, we prove that (1) if $G$ is a connected graph, and its sun toughness satisfies $s(G)\geq\frac{1}{n}$, then $G$ admits a $\{K_{1,t}: 1\leq t\leq n\}$-factor; (2) if $G$ is a $(k+1)$-connected graph, and its sun toughness $s(G)>\frac{k+1}{n+1}$, then $G-Y$ admits a $\{K_{1,t}: 1\leq t\leq n\}$-factor for any $Y\subseteq V(G)$ with $|Y|=k$; (3) if $G$ is a 2-edge-connected graph, and its sun toughness $s(G)\geq\frac{1}{n-1}$, then $G$ is a $\{K_{1,t}: 1\leq t\leq n\}$-factor deleted graph. Furthermore, it is shown that our results are sharp.
The interlacing properties of generalized Narayana polynomials
Authors: Zhao James Jing Yu
Published: November 2024

In this paper, we obtain two new interlacing properties on the zeros of a type of generalized Narayana polynomials arising in the study of the infinite log-concavity of the Boros$-$Moll polynomials. Our tools include a criterion established by Liu and Wang and two new recurrence relations for these Narayana polynomials. The new recurrences are verified with the help of ${\tt Maple}$ package ${\tt APCI}$ given by Hou.
Our results also imply the real-rootedness of these Narayana polynomials.
note on total co-independent domination in trees
Authors: Cabrera Martinez Abel , Hernández Mira Frank A. , Sigarreta Almira José M. , González Yero Ismael
Published: November 2024

A set $D$ of vertices of a graph $G$ is a total dominating set if every vertex of $G$ is adjacent to at least one vertex in $D$. The total dominating set $D$ is called a total co-independent dominating set if $V(G)\setminus D$ is an independent set and has at least one vertex. The minimum cardinality of any total co-independent dominating set is denoted by $\gamma_{t,coi}(G)$. In this paper, we show that, for any tree $T$ of order $n$ and diameter at least three, $n-\beta(T)\leq \gamma_{t,coi}(T)\leq n-|L(T)|$ where $\beta(T)$ is the maximum cardinality of any independent set and $L(T)$ is the set of leaves of $T$. We also characterize the families of trees attaining the extremal bounds above and show that the differences between the value of $\gamma_{t,coi}(T)$ and these bounds can be arbitrarily large for some classes of trees.
Business model innovation in real estate: Applying the business model navigator to conventional and Tokenised models
Authors: Fuensanta Galindo-Reyes , María De la Varga-Salto José
Published: November 2024

This study explores the application of the Business Model Navigator framework to enhance business models within the real estate sector, particularly in response to recent technological advancements and shifting market dynamics. By analyzing two case studies—a traditional luxury property developer and a blockchain-based tokenisation platform—the research demonstrates how selected BMN patterns can drive value creation, improve operational efficiency, and enhance scalability. The traditional luxury real estate model, while excelling in delivering high-end properties and tailored customer experiences, faces significant scalability challenges due to its capital-intensive nature. In contrast, the blockchain-based tokenised model offers improved liquidity and broader market accessibility by enabling fractional ownership, though it encounters obstacles related to regulatory compliance and market acceptance of blockchain technology. This research concludes that both models can significantly benefit from the strategic incorporation of BMN patterns, which enhance adaptability and competitiveness in an evolving real estate landscape. The findings offer strategic recommendations for both traditional and innovative real estate companies seeking to optimise their business models through the use of BMN patterns.
Parametric self-excitation in the dynamic cutting system

Published: November 2024

The problem of ensuring the stability of tool-forming motion trajectories relative to the workpiece, taking into account parametric self-excitation, is considered. The factors causing periodic changes in the parameters of the dynamic cutting system are analyzed. These factors are related to the spatial anisotropy of elasticity properties in the processed workpiece subsystem, variations in the allowance around the perimeter of the workpiece rotation, kinematic disturbances from the mechanical parts of the machine tool’s drive units, and periodic processes in the cutting zone. A generalized dynamic model of the system with periodically varying parameters is presented. The influence of periodically changing parameters on the stability of the trajectories is studied. The specific features of stability loss in dynamic cutting systems are revealed. In particular, it is shown that due to parametric effects, as cutting speed increases and spindle rotation frequency rises, there is always a critical frequency at which the system loses stability.

Isolasi dan Identifikasi Bakteri Brucella sp. pada Darah Kambing di Desa Air Joman Kecamatan Air Joman Kabupaten Asahan
Authors: Sinaga Sabariah , Manalu Kartika , Nasution Rizki Amelia
Published: November 2024

Brucellosis adalah penyakit menular yang disebabkan oleh bakteri Brucella sp., yang dapat menginfeksi berbagai jenis hewan ternak dan manusia. Penyakit ini sering kali menimbulkan masalah serius dalam peternakan dan kesehatan masyarakat karena kemampuannya untuk menyebar melalui kontak dengan hewan yang terinfeksi atau produk-produk hewani yang terkontaminasi. Tujuan dari penelitian ini adalah untuk mengisolasi dan mengidentifikasi bakteri Brucella sp. yang menjadi penyebab Brucellosis pada kambing. Metode yang digunakan mencakup isolasi bakteri menggunakan media TSA (Tryptic Soy Agar) dan uji RBT (Rose Bengal Test), serta analisis data penelitian dilakukan secara kualitatif. Hasil dari isolasi bakteri menunjukkan bahwa dua sampel dari jumlah total sampel darah kambing yang diperiksa menunjukkan hasil positif terhadap bakteri Brucella sp. dengan kode isolat KB1 dan SdJ2 dengan media TSA. Identifikasi dilakukan berdasarkan pertumbuhan koloni yang khas pada media kultur, serta analisis pewarnaan gram yang mengungkapkan karakteristik mikroorganisme di bawah mikroskop. Namun, hasil uji RBT menunjukkan hasil yang kurang memuaskan dalam mendeteksi Brucella sp., dengan tidak adanya penggumpalan dan ketidakkonsistenan warna ungu kemerahan pada serum. Perbedaan ini menyoroti tantangan dalam menggunakan metode tes tunggal untuk diagnosis yang akurat, karena adanya kemungkinan hasil negatif palsu atau rendahnya sensitivitas tes. Oleh karena itu, untuk memastikan diagnosis yang lebih akurat dan dapat diandalkan, disarankan untuk menggunakan lebih dari satu prosedur tes lanjutan, seperti ELISA (Enzyme-Linked Immunosorbent Assay) dan PCR (Polymerase Chain Reaction). Kombinasi metode ini dapat meningkatkan kepekaan dan spesifisitas diagnosa Brucellosis pada hewan ternak.

Published: November 2024

Magnetic flocculants were synthesized on the basis of nanosized magnetite, which acts as a core coated with a protective organic layer - natural polysaccharide (citrus pectin and chitosan), in the structure of which there are specific functional groups that provide highly selective separation and isolation of especially pure products in biochemistry, pharmaceuticals and medicine. The obtained magnetic flocculants were studied by dynamic light scattering. The influence of the concentration and flocculating behavior of magnetic nanocomposites on the sedimentation process of bentonitic clay suspension under the influence of an external magnetic field was analyzed quantitatively in the mode of hindered settling. The opposite sign of the charge of bentonite clay particles and chitosan macromolecules in the composition of the magnetic flocculant indicates a primarily neutralization mechanism of flocculation. During sedimentation of bentonite clay with the participation of citrus pectin, a bridge flocculation mechanism is put into effect. The increase in the size of aggregates is associated with the sequential introduction of polymer additives and the formation of secondary floccules, exceeding the primary ones in size and settling at a higher rate. When the maximum degree of clarification is reached, the precipitate is transformed into a heterophase system in a liquid aggregate state with strongly swollen bentonite clay particles, which shows high adsorption activity with respect to the extracted components. Low values of sediment density and an increase in the compaction constant for systems with individual biopolymers and magnetic flocculants based on them were noted in comparison with a suspension of bentonitic clay without additives. The obtained regularities allow predicting the efficiency and directionality of sedimentation processes of suspensions with the participation of magnetic flocculants.

Nowadays, due to the ever-increasing pollution of water basins, the problem of utilization of process solutions of electroplating plants, in order to reuse them in production, is extremely acute. By qualitative composition, process solutions of electroplating plants contain heavy metals hazardous for the environment. Widely used for the separation of galvanic wastewater gravity sedimentation technology is outdated and does not provide the necessary degree of purification. Constant growth of industrial production scales leads to increase of waste both getting into the environment and placed on waste storage landfills. To prevent environmental pollution by heavy metals it is proposed to supplement the technological process of galvanization with a combined electromembrane unit for treatment of contaminated wastewater. The scheme includes a fine filter, electrodialysis and electron nanofiltration units, evaporator. Application of the above equipment in the structure of the plant allows to receive at the output purified water suitable for reuse in galvanization technology, and sludge with low water content, which is a commercial product for the construction industry. Implementation of the unit in the technological process will allow to reduce the amount of generated toxic waste by 60% in comparison with the classical method of sedimentation. Capital investments for development, installation and operation of the proposed purification scheme are estimated. The efficiency of purification of traditional and electromembrane technologies and the costs of plant operation are compared. It is shown that the funds spent on implementation of combined electromembrane wastewater treatment will be recouped in two years of operation, due to the reduction of payment for environmental pollution and waste disposal, lower cost of plant operation, additional profit from the sale of a mixture of metals (dried renetant).

Renewable energy is becoming more apparent as a key solution to climate change, energy challenges, and economic challenges. As a result of the abundance of solar irradiance, photovoltaic power generation remains one of the most promising energy sources. Despite the wide spectrum of solar irradiance, PV solar cells are only able to convert a small part of it into electricity. The remainder of the spectrum is lost as heat waste, which increases the temperature of the PV panels. As the temperature rises, both the efficiency and lifespan of solar PV panels are reduced. To mitigate the aforementioned issue, thermoelectric generators (TEGs) are used in conjunction with solar PV systems. A TEG is a device that converts thermal energy (heat) into electricity based on the thermoelectric effect caused by a temperature gradient across the thermoelectric module. This paper presents an overview of studies on hybrid PV-TEG systems. In addition to hybrid PV-TEG systems, PV and TEG systems are briefly described. PV-TEG systems are compared with individual PV systems in terms of their major operational parameters, including temperature and power generation efficiency. Finally, an update on recent developments in PV-TEG systems is provided.

Authors: Xin Wee Sherlyn Cheryl May , Lee Hui En , Chua Hong Siang
Published: November 2024

This paper presents an overview of the global vanilla industry, emphasizing vanilla’s status as the second most costly spice and the most extensively used flavoring worldwide. To satisfy global demand, there is an increasing reliance on synthetic methods for flavor extraction, raising concerns about quality and health risks due to widespread adulteration with cheaper synthetic vanillin, often misrepresented as "pure." To tackle adulteration effectively and economically, this study proposes employing a single-stage classification model trained using the transient response of an electronic nose (e-nose) equipped with four metal oxide semiconductor (MOS) gas sensors with Principal Component Analysis (PCA) and machine learning classification models to sample vanilla from various countries (Indonesia & Madagascar) and grades (Grade A & B). 33 classifiers were trained and compared based on classification and validation accuracy. Through trial and error, it was determined that the sensor response times at the 20s, 60s, and 90s marks, using Weighted KNN, contributed to 100% classification accuracy and 80% validation accuracy. A second analysis method was attempted where the sensor transient response was processed using the Wavelet Time-Frequency Analyzer. When training classification models using the processed data, the bilayer neural network yielded the highest classification accuracy of 100% and validation accuracy of 70%.

Lipid bioaktif merupakan nutrisi – nutrisi penting dalam makanan yang berkontribusi terhadap kesehatan manusia. Namun, penggunaan senyawa lipid bioaktif dalam formulasi produk pangan fungsional memiliki keterbatasan, yakni kelarutannya dalam air dan stabilitas yang rendah selama pemrosesan, penyimpanan, serta ketika berada dalam saluran pencernaan sehingga dapat mengurangi bioavailabilitasnya. Enkapsulasi berbasis nanoteknologi mampu mengatasi keterbatasan tersebut dengan cara memfasilitasi penanganan, stabilitas, serta bioavailabilitas lipid bioaktif. Oleh karena itu, ulasan ilmiah ini bertujuan untuk membahas tentang kemajuan terbaru dalam proses enkapsulasi senyawa lipid bioaktif berbasis nanoteknologi. Teknologi nano untuk enkapsulasi lipid bioaktif yang akan dibahas adalah nanoemulsi dan nanostructured lipid carrier. Nanoemulsi adalah emulsi yang memiliki rata-rata ukuran droplet sekitar 20-500 nm. Nanostructured lipid carrier adalah sistem pembawa berbasis lipid yang menggunakan matriks berupa lipid padat dan lipid cair yang distabilkan dengan penambahan surfaktan, sehingga menghasilkan rata-rata ukuran droplet sekitar 10-500 nm. Pembentukan nanoemulsi dan nanostructured lipid carrier dapat diformulasikan dengan menerapkan teknik homogenisasi tekanan tinggi yang akan menghasilkan ukuran droplet yang kecil (skala nanometer) dan memiliki kemudahan dalam pengoperasian alat pada skala industri.

Kalimantan Utara merupakan salah satu Provinsi penghasil rumput laut di Indonesia dimana dari 5 Kabupaten/Kota yang ada di Kalimantan Utara terdapat dua Kabupaten/Kota yang membudidayakan rumput laut yaitu Kabupaten Nunukan dan Kota Tarakan yang diolah menjadi rumput laut kering. Untuk menangani hasil rumput laut ini diperlukan sebuah metode pengeringan yang sesuai dan mudah digunakan oleh masyarakat dan perlu untuk diketahui apa saja metode pengeringan rumput laut dan dampak pengeringan tersebut terhadapat kualitas mutu yang ada di masyarakat terutama masyarkat Kelurahan Nunukan Barat. Berdasarkan hasil observasi yang dilakukan masyarakat setempat memiliki 4 jenis metode pengeringan yang digunakan, yakni metode pengeringan dengan alas, metode pengeringan gantung, metode pengeringan para- para dan metode pengeringan Dome Dryer. Dari ke-4 metode pengeringan tersebut metode pengeringan gantug merupakan metode pengeringan yang memiliki hasil pengeringan yang baik karena dalam proses pengeringannya tidak melakukan pemotongan terhadap pangkal/batang rumput laut walaupun demikinan metode ini kurang diminati oleh masyarakat setempat dan lebih memilih metode pengeringan para-para yang dinilai lebih efektif oleh masyarakat. Untuk metode pengeringan dengan alas memiliki permasalahan dalam segi higenitas dan proses pengeringan yang tidak merata sedangkan metode pengeringan Dome dryer dinilai tidak efektif oleh masyarakat karena dapat merusak rumput laut yang dikeringkan.
