Defending a wireless LAN against ARP spoofing attacks using a Raspberry Pi
Authors: Nasser Hiba Imad , Hussain Mohammed Abdulridha
Published: January 2023

The Address Resolution Protocol (ARP) is a protocol that converts Internet Protocol (IP) addresses to Media Access Control (MAC) addresses. Due to a security issue known as "Man in the Middle," identity theft is feasible using the ARP protocol. ARP spoofing is one of the weaknesses in wireless networks when an attacker effectively masquerades as a legitimate one. Spoofing attacks will reduce network performance and break several security measures. In networks that use MAC address-based filtering to verify clients, all a spoofer needs is an actual MAC address from an authorised client to gain an unfair advantage. The research recommends developing a security system recognising and preventing ARP spoofing attacks. This system detects ARP spoofing attempts by comparing the static MAC address of the original router to the router's MAC address in the ARP cache table. After detecting the attack using information collected from the router's MAC address in the ARP cache table, the system will conduct a de-authentication attack against the attacker's MAC address. If the attacker is disconnected from the WLAN, they cannot perform ARP spoofing attacks. This system is operated using a Raspberry Pi Model B. Most ARP spoofing attacks can be detected in 0.93 seconds, and responding takes 3.05 seconds.

The reliability of the electric power system is very important in the continuity of the supply of electrical energy to the load. One of the important parts in the electric power system is the transformer. Maintaining the reliability of the transformer is an effort to make electrical energy channeled properly. For this reason, efforts are needed to evaluate whether the transformer is in good condition or not by using the Weibull distribution. By looking at the average failure rate, the MTTF value is used as a benchmark for reliability. It is based on the number of disturbances that cause the transformer to fail to operate. The results of the reliability analysis with the Weibull distribution on distribution transformers in the Rungkut ULP area during the time span from 2019, 2020, 2021 obtained an average failure rate of 18.321894% per year, with an MTTF value of 0.054579 per year, so the value reliability obtained 0.981. So according to Croanbach alpha, this value belongs to a very reliable level.

Often electronic equipment is damaged due to a sudden power outage. This often happens due to uncertain natural conditions, forcing PLN to carry out maintenance on its electricity distribution equipment. In addition, many electrical equipment can be damaged by sudden power outages. To be able to overcome this, people usually use generator to overcome supply failures manually. Based on this background, the author created an Automatic Transfer Switch (ATS) – Automatic Main Faillure (AMF) based on the STM32F103C8T6 microcontroller which is applied to generators when there is a power outage. The ATS – AMF device is made using Relays, PZEM004T Voltage Sensors, magnetic contactors, Miniature Circuit Breakers, stepdown circuits, LCD TFT and STM32F103C8T6 as control systems. This system uses the Fault Tolerance method so that the system can continue to run even if there is damage to the main battery by adding a backup battery as a backup. The results of this study, the Automatic Transfer Switch (ATS) circuit found that the average time needed for the generator to start is 2.5 seconds and the time needed for the generator to produce a stable voltage is 5.7 seconds, thus this time is used as the author's reference in determining the right time to switch the load on the microcontroller so that the load is not damaged due to unstable generator voltage. Whereas in the Automatic Main Failure (AMF) it was found that the Stepdown circuit used to detect whether or not PLN electricity was very responsive because the stepdown circuit was installed in parallel at the PLN source and can be proven by the results in the Arduino application.

Published: January 2023

In running a business, companies are required to have good governance or commonly referred to as good corporate governance. Good corporate governance is a set of rules, practices, and control processes of a company to maximize the value creation of the company as an economic entity based on the application of general basic principles. This article will discuss the concept of good corporate governance with agency theory. Agency theory is the most appropriate basis for understanding corporate governance. Agency theory is a theory that explains the relationship that occurs between the management of the company as an agent and the owner of the company as the principal. Agency relationship is a contract in which one or more people (principals) instruct another person (agent) to perform a service on behalf of the principal and authorize the agent to make the best decisions for the principal.

Sobre el papel de la phantasia en el teatro y en la novela
Authors: Richir Marc , Posada Varela Pablo
Published: January 2023

Traducimos al español el artículo de Marc Richir «Du rôle de la phantasia au théâtre et dans le roman», publicado en la revista Littérature, n.º 132 en diciembre de 2003. El artículo empieza conceptuando la diferencia fenomenológica entre phantasia e imaginación según Husesrl. Más adelante, el autor se detiene en el examen de la llamada phantasia «perceptiva», distinta tanto de la percepción como de la imaginación. La phantasia «perceptiva» le permite a Richir, junto a Husserl, abordar el análisis fenomenológico del teatro y de sus paradojas, necesario preámbulo al análisis de lo que está en juego, fenomenológicamente, tanto en la escritura como en la lectura de una novela.

Buscamos, dando a Eikasía este manuscrito de los tutoriales y distintas pre-prologías de un Quijote N+7 (cuyo «prolongamiento» sin estos paratextos saldrá, plausiblemente, en relativa sincronía en Impossibilia: http://impossibilia.org/index.php/impossibilia/article/view/306/325) lo que Balzac ya denominaba la necesidad de «en dire la pensée, d’en raconter l’origine, d’en expliquer brièvement le plan, en essayant de parler de ces choses comme si je n’y étais pas intéressé». Lo damos, pues, tal cual: echándolo al olvido, poniéndolo en escena, dejándolo al albur de variopintos hermanamientos. Y en una escena esta, por añadidura, donde la rumia se establece escribiendo contra el propio texto in fieri. Otra manera (sintomática, fenomenológica y dialéctica), en suma, de querer introducir un poco de Gründlichkeit en el capriccio.

El diálogo que aquí se transcribe discurre por Sevilla y el pensamiento de Ortega y Gasset. Se va hablando de la razón topográfica, de cosmopolitismo y de Don Juan, figura objeto de una reflexión filosófica que imita los métodos de dos escuelas antiguas: el diálogo socrático y el paseo peripatético. Partiendo del parque de María Luisa, la conversación recorre el centro de la capital hispalense hasta el barrio de la Macarena, sigue el curso del Guadalquivir, recala en Casa Robles y termina frente a la Maestranza. En última instancia, no se hace sino poner en perspectiva o situación algunas meditaciones magistralmente escritas por Ortega y tirar del hilo. Con ello actualizamos dos claves orteguianas que consideramos fundamentales: la concepción de la vida como diálogo con el contorno y la condición dramática del pensar

Alcune riflessioni sulla teologia sottostante la filosofia linguistica
Authors: Arias Navarro Javier
Published: January 2023

Nel 1929 avviene a Davos il famoso incontro tra Ernst Cassirer e Martin Heidegger che rappresenta il dibattito tra le correnti filosofiche dominanti nel mondo di lingua tedesca in quel momento, mentre ci si focalizza, nella sua risoluzione, sull’immediato futuro politico che avrebbe dovuto riguardare l'Europa, con i soliti mitmachen dell'università e della stragrande maggioranza dei suoi intellettuali, tra cuianche buoni sacerdoti e i barbieri di Cervantes, che bruciavano libri.

Esattamente quattro secoli fa, tra gli altri, Lutero e Zwingli hanno discusso nel cosiddetto Colloquio di Marburg, sul sacramento dell’Eucaristia, prendendo posizioni inconciliabili riguardo alla questione della presenza reale di Cristo in essa.

Il presente documento intende dimostrare l'identità strutturale tra la discussione di Davos e quella del colloquio di Marburg, rivelando le sue dimensioni teologiche, che avranno, conosciute o meno, un enorme impatto sull'ulteriore sviluppo di discipline come la linguistica.
Lógica, corporeidad y cuidado de sí: Foucault y los estoicos antiguos
Authors: Pascual Summers Jaime
Published: January 2023

En la medida en que se hace cada vez más evidente que la generalización de la lectura y la escritura en las sociedades de la información, la construcción mediática de identidades y la acción automática de los algoritmos de búsqueda como elementos restrictivos de la imagen del mundo constituyen elementos que afectan al desarrollo moral de individuos y comunidades, entendemos que las concepciones rectoras tanto de las acciones como de la comprensión que de sí tienen los individuos remiten a un pensamiento acerca del sujeto, del lenguaje y del ser que difieren con respecto al funcionamiento real de nuestra cultura, aunque parecen resultar indispensables como señuelos que lo hacen posible. El propósito de este texto es apuntar algunas líneas de lectura que expliciten cómo el asunto del cuidado de sí dispone un conjunto de prácticas orientadas a la construcción de la individualidad que suponen una concepción del signo y de la enunciación que conducen a una alternativa con respecto al modo habitual en el que la subjetividad es comprendida en nuestra época.
visage de l’inimitié politique
Authors: Bez Micol
Published: January 2023

Quelles sont les conditions pour une rencontre éthique avec l’autre? Cet article porte sur une question précise, à savoir si les spécificités historiques d’un ordre ontologique donné ―comme le colonialisme― peuvent empêcher la possibilité d’une telle rencontre. Est-ce qu’une relation éthique est toujours possible, lorsque l’autre se trouve être réifié, ontologiquement amoindri, voire dépourvu de son humanité? L’auteure propose d’affronter ce problème en instituant un dialogue entre la philosophie de Franz Fanon et celle d’Emmanuel Levinas.

Dans un premier temps, l’article explique la difficulté que la pensée de Fanon pose à l’éthique levinassienne; ensuite, il tâche de montrer comment l’éthique levinassienne pourrait fonctionner dans le cadre (ou au-delà du cadre) de l’ontologie négative de Fanon. Dans un troisième temps, une critique de certains aspects de la philosophie levinassienne de l’altérité nous amènera à interroger le problème du tiers et de l’ennemi, afin de réfléchir sur les limites de la réponse éthique au problème proprement politique de Fanon: l’inévitabilité de la cruauté et de la violence politique.

Published: January 2023

: Globally, due to lifestyle changes, type 2 diabetes is rampant causing a serious health concern and more so in developing countries. The disorder threatens to reach pandemic levels if actions are not taken and the situation is critical in Kenya, since diabetes prevalence is on the rise which threatens the health of general public and national economy. Unfortunately, little progress has been achieved in the management of diabetes regardless of numerous initiatives. This predisposes patients to complications and mortalities which can be averted. Dietary practices play a fundamental role in managing type 2 diabetes mellitus whereby it reduces blood sugar levels that help in both prevention and management of type 2 diabetes mellitus. Moreover, dietary practices help in weight loss that would otherwise lead to overweight and obesity which predisposes individuals to insulin resistance. The study, for that reason, sought to assess dietary practices and blood sugar level among adults (19-60 years) with type 2 diabetes attending Meru Teaching and Referral Hospital. A cross-sectional analytical study design was applied on a comprehensive sample of 157 type 2 diabetes mellitus adults attending the hospital. Data were collected using a semistructured questionnaire, focus group discussion guides and key informant interviews. Glycated hemoglobin was used to test for the blood glucose levels while dietary diversity score, 24-hour dietary recall Questionnaire, food frequency questionnaire was used to determine dietary practices. Data obtained was coded, cleaned, entered in Ms-Excel and analyzed using Statistical Package for Social Sciences Software version 20. Noteworthy, 86.6% had high glycated hemoglobin with a mean of 9.7±2.64. In addition, energy intakes (1971 kilocalories) were below the recommended values in both males and females. Pearson correlation for carbohydrate was (P-value <0.014) which was significant among other selected nutrients (Table 6). Adhering to good dietary practices have positive influences on the blood glucose levels of participants. Therefore, there is need for informed and up to date facts and coordinated information by health care stakeholders to the diabetic adults to ensure they grasp the correct information.

Authors:   University of Nairobi, Muthike Caroline , Imungi Jasper ,   University of Nairobi, Kogi_ Makau Wambui ,   University of Nairobi
Published: January 2023

: Globally, 18.1 million new cancer cases out of which 9.6 million deaths occurred due to cancer in the year 2018. Consumption of vegetables and adopting a healthy lifestyle has been shown to be the way to reduce the risk of preventable cancer. The mechanisms in which vegetables prevent cancer occurrence, progression and survival are areas that have limited information hence knowledge gaps. The objective of this review is, therefore, to establish if African leafy vegetable could have chemoprevention potential against various types of cancers. The study selection was based on defined keywords (cancer chemoprevention and African leafy vegetables). A search was carried out on PubMed to retrieve all publications on cancer chemoprevention and African leafy vegetables. Only studies that met the search criteria were retrieved and the required data obtained. Data were synthesized by obtaining eight studies that met the criteria. The publications were analysed to establish whether African leafy vegetables could prevent cancer and the mechanisms of prevention. Amount or doses of the vegetable extracts used were also noted. The articles reviewed indicated that African leafy vegetables had a cytotoxic effect, or the vegetables contain anticarcinogenic effect in both human cancer cell lines and animal models. African leafy vegetables that had cytotoxic of anticarcinogenic effects were: Amaranthus, mustard, Ethiopian kale and Nauclea pobeguinii. Sweet potato leaves showed some compelling evidence of anti-cancer properties.

In Kenya, it remains a major problem regardless of ways being availed to tackle this. The research was carried out to determine the relationship between culture and child nutrition in Kakamega County, Kenya with the focus being on Sheywe ward, Lurambi Sub-county. The target population was children under 5 years and their caregivers. The objectives for this study were; to determine the impact of aspects of culture on child nutrition, to establish the negative cultural practices that impact on nutrition and feeding practices of children, to find out the cultural interventions used to avert malnutrition in children and to investigate the mother’s sources of information with regard to infant and young child feeding. The study adopted the analytical cross-sectional study design. Sampling technique used was simple random sampling. A total of 59 households with children of age 0-60 months participated in the study. An interviewer-administered questionnaire was used to assess if breastfeeding was practiced exclusively, the type of complementary foods given to the infant, maternal nutritional knowledge and sources of nutritional knowledge. The study identified factors such as educational level(p=0.029) impacted on understanding of exclusive breastfeeding. Findings established that complimentary feeding started at an early age among a larger majority of the respondents. This study aimed to inform programmes targeting nutrition education among mothers and caregivers in the rural and urban setting.

INDUCTION OF SPECIFIC BIOCHEMICAL PATHWAYS IN PLANTS FOR PEST MANAGEMENT
Authors:   G.S. Gill Research Institute, Guru Nanak College, Chennai 600 042, Tamil Nadu, India., Sanjayan K P
Published: January 2023

ABSTRACT The biochemical pathways encompassing induced resistance involve oxidizing enzymes such as PPO (Polyphenol Oxidase), PO (Peroxidase) and LOX (Lypoxygenase). Increased activities of these enzymes in plants serve as markers for visualizing induced resistance. Induced resistance, being an active defense mechanism, results from the expression of PR-proteins, low molecular weight compounds like phytoalexins and proteinase inhibitors. This paper highlights on the spatial induction, variability and persistence of induced defenses responses in Lycopersicon esculentum Mill. using lepidopterans, aphids and mechanical wounding as elicitors. The early signally events upon wounding by an insect resulting in the release of elicitors JA, Ethylene, Glycans and Absisic acid and the transmission of signals through unwounded sites is described. The practical utility of induced resistance is discussed based on the results of the systematic small scale laboratory essays.

ABSTRACT In the process of host location and selection several cues associated with host’s play a major role. Volatile compounds emitted by plants as a consequence of herbivore activities are often attractive to insect natural enemies including the Hymenopteran egg parasitoids, Trichogramma species. We studied the plant - parasitoid interactions where the plant surface chemicals act as infochemicals that attract or arrest the parasitoids for egg parasitization and strategically help in preventing the pest infestation. The leaf surface chemicals of R. communis, damaged due to the feeding of the host, Achaea janata (L) (castor semilooper) (Lepidoptera: Noctuiidae), and a non – host, Serpentine leaf miner Liriomyza trifolii (Burgess) (Diptera: Agromyzidae) were evaluated for their influence on host location, host acceptance and ovipositional behavior against the egg parasitoid, T. chilonis in laboratory bioassays. The A. janata damaged leaf emissions had synomonal effects on the parasitoid and induced orientation and oviposition, whereas, the surface chemicals from the plant infested with non-host L. trifolii ceased to produce any such effects. The maximum egg parasitization was observed in A. janata infested castor leaf extracts compared to the leaf miner infested or normal healthy castor leaf extracts. The results are interesting in the context of tritrophic interactions between the pest, parasite and the host plant and are useful in biological control of insect pests.

ABSTRACT Plant parasitic nematodes are parasitized and preyed by a variety of soil organisms which includes predatory nematodes, fungi, bacteria, viruses, protozoans, turbellarians, tardigrades, mites and other microarthropods. One such spore forming and an obligate parasite is Pasteuria penetrans. The major limitation in the use of Pasteuriaspp. is their inability to grow in the absence of host nematodes. In vivo systems although proven are unlikely to be adopted for large scale application in most farming systems. Attempts were made to culture the organism in in vitro. Among the symbiotic bacteria used for mass production co-culturing with Enterobacter proved to be successful in culturing this obligate organism in a specially developed medium for mass multiplication.

The insecticidal activity of crude extracts and fractions of Argemone mexicana L. (Papaveraceae)was investigated against Spodoptera litura Fab. (Noctuidae: Lepidoptera). The different treatments differed significantly in their efficacy. Pupation was nil in chloroform extract and acetone extract, while water extract treated larvae resulted in least pupal weight and maximum malformed adults. The adult life span was least in acetone solvent followed by hexane and petroleum ether extracts. Most of the treatments resulted in nil fecundity. Among the chloroform fractions, the first fraction arrested the pupation. In addition, disturbed moulting, larval-pupal intermediates and malformed moth emergence/dead pupae were also observed.

Ten plant products were evaluated against Henosepilachna vigintioctopunctata. They were: Azadirachta indica (Neem) leaf extract (@ 5.0 %), Calotropis gigantea leaf extract @ 5.0 %, Lantana camera leaf extract @ 5.0 %, Neem cake extract @ 5.0 % neem oil @ 2.0 %, Nimbecidine®@ 2 ml /lit %, Pongamia glabra (Pungam) leaf extract @ 5.0 %, Prosopis juliflora L. leaf extract @ 5.0 %, Vitex negundo(Notchi) L. leaf extract (@ 5.0 %), and Allium sativum (Garlic) extract (@ 5.0 %. The standard check, carbaryl (Sevin 50 WP) (@ 0.1%) and an untreated check were included. The plant products were able to bring about higher reduction in population of H. vigintioctopunctata from 87.86 to 71.97 % on the third day after spray. However, the efficacy was reduced with the increase in days after spray. Higher reduction in population of H. vigintioctopunctata was observed in neem oil and was on a par with C. gigantea , Nimbecidine and L. camera ; P. glabra neem cake extract and V. negundo stood next. However, the plant products were less effective than the standard check carbaryl but better than the untreated check.

The study was conducted both in the greenhouse and field from August 2003 to August 2004. Trathala flavoorbitalis is an efficient parasitoid of both Brinjal shoot and fruit borer (BSFB) and Rice leaffolder (RLF) but its parasitism efficiency on BSFB larvae is higher than that of RLF larvae. The highest parasitism rate by T. flavoorbitalis on BSFB larvae in August is 36% & July is 47% and on RLF larvae in November is 26% & Mid March-April is 28%. The parasitism rate of T. flavoorbitalis was always significantly higher in BSFB larvae than that of RLF. The parasitism of BSFB larvae was 1.52 to 2.14 folds higher than that of RLF. In the confined condition of cage or microplot, when T. flavoorbitalis was given a choice to parasitize BSFB and RLF larvae, they preferred more BSFB larvae

The knowledge on diversity and distribution of spiders in Rajasthan is sparse as compared to other regions. There is a dire need of research regarding species composition, distribution pattern so that their role in controlling insect pests could be ascertained. Present study examined a novel approach for documenting the diversity of spider fauna in arid and semi- arid (Ajmer and Jodhpur) region of Rajasthan, India. A regular survey of spider faunal complex was conducted in four major habitats namely, woodland, wetland, pasture and caves/crevices/rocky area. Maximum number of spiders was found in woodland habitat and the minimum number of spiders were collected and identified from caves/crevices/rocky area with 31.86 and 17.61 relative abundance, respectively. Similarly, diversity indices viz., richness, evenness, Shannon-Weiner and Simpson indexalso indicated the maximum species richness in woodland and minimum in caves/crevices/rocky area. In woodland, Araneidae and Oxyopidae were found as most abundant families with 41.44 and 15.78 percent of total spider fauna while Lycosidae wasfound as the most abundant family in wetland but was at par with Araneidae in pasture habitats. In Caves/crevices/rocky area, family Pholcidae was found as the most abundant.

In an endeavour to explore secondary metabolites as an important and safe means of pest management, we investigated the effects of pyrogallol, a phenolic compound, on the growth and development of Spodoptera litura (Fab.). It is a serious pest of a large number of economically important crops. Different concentrations viz., 1, 5, 25, 125, 625, 3125 ppm of pyrogallol were incorporated in artificial diet of larvae and the antibiosis influence was ascertained by feeding second instar larvae on this diet. The larval and total development period increased significantly with increase in concentration of the pyrogallol. Inhibitory effects of the compound were observed on per cent pupation, per cent emergence and adult longevity. All nutritional indices were also significantly affected. Thus it can be considered as a promising substance to be used as a biopesticide against the insect pest.

Plant diseases caused by fungi are one of significant destructive pathogens to economiccrops of Thailand and worldwide. The most common plant pathogenic fungi infectedcrops in Thailand are Pyricularia oryzae Cavara., Rhizoctonia solani (J.G Kuhn),Phytophthora palmivora Butler., Sclerotium rolfsii Sacc., and Colletotrichum gloeosporioides Penz. and Sacc. Control of these pathogens is by using syntheticfungicides which are expensive and harmful to environment. This study aims at investigating the efficacy of the extract of five plants - Hydnocarpus anthelminthicus Pierre ex Laness., Crateva magna (Lour.) DC., Caesalpinia sappan L., Xanthophyllum lanceatum J. J. Sm., and Carallia brachiata (Lour.) Merr. to inhibit the growth of five plant pathogenic fungi in in vitro conditions at various concentrations. At the 10,000 ppm concentration H. anthelminthicus fruit extracts exhibited reduction in antifungal potential to growth inhibition, and recorded 100 % growth inhibition against P. oryzae, P. palmivora and R. solani followed by S. rolfsii at 96.33 % when compared with water control. X. lanceatum fruit extract that logged excellent inhibitory activity against P. oryzae. Antifungal potential was observed with the extract of C. sappan, which recorded the best inhibitory activity against P. palmivora and S. rolfsii at 88.89 and 78.89 % respectively. Results from this study demonstrated that the ability of some plant extracts viz., H. anthelminthicus, X. lancelatum and C. sappan could be used to control the growth of plant pathogenic fungi and may be applied as an alternative method to reduce fungicide
