Published: June 2024

Bangladesh, with its dense population and diverse ecological landscape, embodies a unique environmental tapestry. This study explores the intricate interplay between tree phenology, seed dispersal seed germination, and biometric characteristics within the context of Bangladesh's rich biodiversity. Through field research conducted from 2020 to 2023 in the Chittagong division, we investigated species such as Artocarpus chama, Avicennia officinalis, Terminalia arjuna, Terminalia bellirica, and Terminalia chebula. The findings reveal significant variations in seed morphology, phenology, germination, and ecological roles among these species. Furthermore, through dendrogram analysis and principal component analysis (PCA), we elucidate the underlying patterns and relationships governing biometric variability. These insights provide valuable contributions to our understanding of ecological processes and inform conservation strategies aimed at preserving Bangladesh's forest tree biodiversity.

Published: July 2024

Internet of Things (IoT) connected devices will be reaching people seamlessly in future days. The security aspects for the IoT domain have always been open feld of research and analysis. Each of the IoT protocols have its own strength and vulnerabilities. The Message Queue Telemetry Transport (MQTT) application layer IoT protocol is widely used in present day’s context. Since, MQTT standard has no mandatory requirements regarding the security services; therefore, manipulating the security issues in MQTT platforms seems very easy. This work looks into the security analysis of this protocol. Basing on the analysis, a security enhanced Message Queue Telemetry Transport (MQTT) protocol is proposed. The proposed protocol is based with added cryptographic primitives to ofer security services for IoT system. Mutual authentication between subscriber and broker, mutual authentication between publisher and broker, authentication with key distribution, use of only symmetric key cryptography are the few salient features of the proposed enhanced MQTT protocol. This work also conducts a formal verifcation for the proposed MQTT protocol to prove that the proposed protocol satisfes the intended security attributes. The ProVerif result validates that the proposed protocol ensures the secrecy property of the cryptographic credentials and hence, operates securely.

Authors: Özyüksel Mihrioğlu İlke , Kalfa Murat
Published: June 2024

Genç ve nitelikli bireylerin, kariyerleriyle ilgili geniş bir anlayışa sahip olmaları sağlıklı bir süreç geçirilmesi açısından önemlidir. Son dönemde sadece tek bir mesleğe yönelimin yer aldığı kariyer olgusundan çok uzun vadede bireyin gelişimine odaklı bir şekilde katmanlı bir yapı olarak karşımıza çıkan çift yönlü kariyer yaklaşımına rastlanmaktadır. Çift yönlü kariyer, her iki meslek alanında özel uzmanlık ve deneyim gerektirirken, bu yaklaşımın bireye farklı alanlarda statü, unvan ve kariyer yolları sunmaktadır. Bu yaklaşımla hem eğitim hayatını hem de kariyerini sürdüren bireylerin bir bölümünü de sporcular oluşturmaktadır. Hem spor kariyeri hem de eğitim hayatı devam eden öğrenci sporcular akademik başarı elde etmeye çalışmanın yanı sıra yoğun antrenman ve maç programları, kamplar ve okul takımında yer alma gibi çeşitli sorumlulukları eş zamanlı olarak yürütmektedir. Spor dallarına göre değişiklik göstermekle birlikte, hem biyolojik faktörlerin etkisiyle spor kariyerinin belli bir yaşa kadar devam etmesi, hem de sürekli bir sakatlık riskinin varlığı, çift yönlü kariyerin spor sonrası yaşam için önemini artırmaktadır.

Published: June 2024

The organic salts are a broad class of ionic chemicals with a variety of properties. Scientists have an interest in violurate salts because of their bright color and crystal structure.  In this study, 4-chloroanilinium violurate salt was synthesized and identification using infrared spectroscopy, 13C NMR spectroscopy and Electrospray ionization (ESI). Density functional theory (DFT) calculations have been performed using B3LYP/6-31++G**, and CAM-B3LYP/6-31++G** levels of theory. Practically, chloroanilinium ion (M+H)+ has a relative abundance of 100% in ESI+, indicating its excellent stability. The protonation formula for violuric acid (VA+H)+ shows instability, despite the observation of a low abundance of the (VA+3H)3+ ion. DFT calculations demonstrate the exothermic nature of the salt formation reaction. The calculated enthalpy change is -26.861kJ in the B3LYP/6-31++G** level of theory and -31.82kJ in the CAM-B3LYP/6-31++G** level of theory
Role of malic acid in enhancing the efficiency of barley (Hordeum vulgare L.) and alfalfa (Medicago sativa L.) plants for phytoremediation of salt affected soil
Authors: Radhi Sara F. , Abdul-Qadir Luma H.
Published: June 2024

Soil salinization is a growing global problem that inﬂuences plant growth and crop productivity. Most of the reclamation efforts in the past have focused on the installation of surface drainage systems. Other  management approaches, such as excessive leaching and chemical amendments, have also been used on a limited scale to enhance the productivity of these soils. Phytoremediation can be cost-effective and environmentally sound technology.A laboratory experiment was carried out to study the role of malic acid which is low molecular weight organic acid (LMWOA) in enhancing the efficiency of barley and alfalfa plants for the phytoremediation of salt-affected soil. Seeds of barley and alfalfa were cultured in pots and irrigated with full strength Hoagland nutrient solution with three concentrations of seawater (SW) (10%, 20% and 30%) and a mixture of seawater with malic acid (MA) at 2, 4 and 6 mM l-1 (MA+SW), Hoagland solution was used as control. After twelve weeks, plants were harvested, and three types of soils (barley soil, alfalfa soil, and plant-free soil) were subjected to physical and chemical analysis for EC (electrical conductivity), TOC (total organic carbon), pH, potassium, sodium, and chloride ions. Results indicated a significant decrease was recorded in soil EC, pH, potassium, sodium, and chloride ions and a significant increase in soil TOC in barley and alfalfa soil compared with plant-free soil. Treatments with (MA+SW), especially at (2+10%) resulted in a significant increase in ions availability and phytoremediation activity in barley and alfalfa soils comparing with plant-free soil.
Adoption of Bloom Filter and Firebase Framework to Enhance Authentication Time for Healthcare Systems Based on Blockchain Technology
Authors: Al-ali Mowafaq , A.Yassin Ali , Ali Abed AL-Asadi Hamid
Published: June 2024

Healthcare offers several advantages for actual-time smart healthcare.  security concerns are growing due to its constrained computing power, storage capacity, and self-defense capabilities. The tamper-resistant decentralized architecture of more recent blockchain-based authentication solutions gives them significant security features, but they come with a high resource cost because they need a lot of processing power, additional storage, and lengthy authentication processes. Therefore, these challenges offer impediments to achieving the optimal degrees of temporal efficiency and scalability, which are critical for the effective operation of large-scale, time-sensitive IoHT systems. Our work provides an authentication solution specifically created for healthcare systems to address these issues. We work in three phases: initializing, registering, logging in, and authenticating. The suggested system combines blockchain technology, Firebase Framework, Bloom Filter, Multi-Factor authentication, and other elements to improve security and efficiency at the same time. We use the Python programming language to simulate the work, and our findings indicate that the Bloom filter decreases the amount of time it takes to determine whether a person is in the system compared to the previous way. Moreover, using Firebase may reduce transaction numbers by up to 73%. Using the Scyther tool, a security analysis of the proposed scheme proved that the suggested plan is safe from possible threats and maintains the IoHT system's scalability

Authors: Shaker Hala , Al-Darraji Salah
Published: June 2024

The growing prevalence of face recognition technology in various applications, including mobile devices, access control, and financial transactions, highlights its importance. However, the vulnerability of face recognition systems to attacks has been demonstrated, underscoring the necessity of addressing potential weaknesses that attackers may exploit. The paper delves into face presentation attack detection (PAD) within biometric systems, which is crucial for ensuring the reliability and security of face recognition algorithms. To address this issue, the paper proposes a method for face presentation attack detection using ResNet-50 in conjunction with multi-modal data, incorporating RGB, depth, infrared (IR), and thermal channels. The method explores diverse strategies to combine results from each modality, investigating various fusion techniques such as majority voting, weighted voting, average pooling, and a stacking classifier. The system has been tested on the WMCA dataset. It exhibits strong performance compared to existing methods, notably achieving an impressive ACER ratio of 0.087% with the stacking classifier. This approach proves effective by consolidating multiple modalities without requiring individual scenario-specific models, indicating promise for real-world applications

A morphological comparative study of proboscis sensilla between Pierinae and Coliadinae (Lepidoptera: Pieridae)
Authors: Mengi Yagmur , Seven Çalıskan Selma
Published: June 2024

Pontia edusa (Linnaeus, 1758) and Colias croceus (Geoffroy, 1785 in Fourcroy), which are in different subfamilies within Pieridae, feed on nectar. In this study, we tested the hypothesis that sensilla differ in the subfamily category. For this purpose, we investigated the ultrastructural structure of proboscis and sensilla in Pontia edusa (Pierinae) and Colias croceus (Coliadinae) by scanning electron microscopy (SEM). The composition of the wall of proboscis, their surface structure, the shape and distribution of different types of sensilla were compared. Three sensillum types are located on the proboscises of both species, sensilla chaetica, sensilla basiconica, and sensilla styloconica being most common in Lepidoptera. It was determined that the size and distribution of sensilla and especially the structure of sensilla styloconica differ in two species. The results will contribute to studies on food and proboscis morphology of Lepidoptera, and will also be beneficial in further studies on the significance of proboscis and sensilla structure in classification

Authors: Ms. REKHA
Published: June 2024

George Orwell's novella Animal Farm, published in 1945, is a masterpiece of political satires. The book is a fable which sets in the animal farm of Mr. Jones of England. The book is symbolic as it targets the socialism in Russia under Stalin's leadership. The animals of the Manor Farm inspired by the words of Old Major the oldest boar, revolt against the tyranny of Mr. Jones and expel him out of the farm. After the rebellion, the hold of farm comes in the hands of two senior boars Snowball and Napoleon. Snowball is a vivacious, quicker in speech and more inventive while Napoleon is large, fierce-looking and with habit of getting his own way. Napoleon being more ambitious rears puppies secretly. At every point he shows his disagreement with Snowball. In the matter of windmill, the hostility reaches on the highest point when Napoleon lets his dogs to attack over Snowball and compels him to leave the farm forever. With the help of Squealer and dogs, Napoleon becomes the dictator. He including other pigs enjoys luxury and distorts all the commandments that were established just after rebellion. Thus, the power that was at first in the hands of one tyrant i.e., human being now transfers into the hands of another tyrannical dictator i.e., Napoleon, the boar. The paper analyses how power hunger leads to the depravation and subjugation of fellow beings.

Authors: Jannah Raudlatul , Quthny Abu Yazid Adnan , Nugroho Irzak Yuliyardy
Published: June 2024

Fulfillment of divorced children: Most fathers do not carry out their obligations to support their children and there are no sanctions for fathers who have carried out these obligations. This is the background to the issues raised, namely what are the legal sanctions for fathers who do not carry out their support obligations towards their children after divorce and what are the provisions on the father's support obligations towards children from the perspective of Islamic law and positive law in Indonesia. This type of research is library research, with primary legal materials and secondary legal materials and then analyzed as expected based on normative descriptive analysis. From the results of this research, it shows that the legal sanctions for fathers who do not support their children after divorce from an Islamic legal perspective have disparity, namely the opinion of Hanafi scholars that the child's previous support becomes the father's debt even though the father is poor, so that by the time the father is able to then father must replace it. However, if the father is capable but refuses or even does not provide support for the child, the judge is obliged to force the father to pay the support. According to the opinion of the Syafi'i Hambali and Maliki Schools, the child's past documents are invalid unless there is a decision from a judge, whereas according to positive law in Indonesia, legal sanctions for a father who neglects his obligations, namely supporting children after divorce, can be subject to civil and criminal law sanctions.
How influential is politics for Indonesia?
Authors: Naswa Nabila
Published: June 2024

The relationship between law and politics, as discussed in the field of legal studies, examines how law operates within a specific political context. The term "legal politics" consists of two words: politics and law. Etymologically, the relationship between politics and law in the context of legal politics can be explained as follows: In the Dutch language, the term for legal politics is "rechtspolitiek." Rechtspolitiek is a compound word consisting of "recht" (law) and "politiek" (politics). The word "recht" refers to the system of rules that govern behavior in society, known as law. On the other hand, "politiek" or "beleid" means politics (policy). Legal politics is the exercise of power with rights and authority over a law. It serves various purposes: 1) In the socio-political sphere, legal politics aims to ensure justice in society. It strives for the application of fair rules for the community, avoiding any biases or favoritism, both in laws and other regulations, 2) Legal politics is beneficial in maintaining legal certainty to create a sense of security and tranquility in society. All rules, whether new or existing, should be based on reliable and logical sources. Rules should be used appropriately and in accordance with the law dan 3) In concrete social life, legal politics aims to regulate genuine interests. This is applied, for example, when the government enacts laws that align with the collective aspirations of society and support them.
