Authors: Radhakrishnan Rekha P , Janam Presanthila , Nayar Bindu Radhakrishnan , Jayasree Lekshmi A
Published: December 2023

The ultimate aim of periodontal therapy is regeneration. Traditionally, many techniques and agents were used. The therapeutic outcome in treatment of intra bony defects can be augmented with the use of growth factors alongside bone grafts. The present clinical trial was designed to assess the efficacy of an alloplastic composite graft and the combination of autologous platelet rich fibrin with the graft in the management of intra bony defects.

A total of 45 systemically healthy patients with intra bony defects indicated for flap surgery were selected from the outpatient department of periodontics. The patients were divided into three groups with the help of a computer generated random number table. Age, sex, and periodontal parameters (probing pocket depth, clinical attachment level, gingival marginal level, plaque index, modified sulcus bleeding index) and presence of intra bony defects were recorded. The defects in group I patients were treated with autologous PRF along with the graft, group II with graft, and group III with open flap debridement alone. All the patients were recalled at 3, 6, 9 months after surgery, and the periodontal parameters were recorded in each recall.

The baseline parameters were compared with 9 month post op periodontal parameters by non parametric test for ANOVA (Kruskal Wallis). Maximum pocket depth reduction (5.86±1.03) maximum gain in attachment (4.64± 1.08), reduction in modified sulcus bleeding index were seen in group I, which is statistically significant between the groups. Though change in gingival marginal level is minimum for group I (1.21± 0.42), it was not statistically significant. Group I showed the maximum percentage of sites with bone fill (92.9%) which was also statistically significant when analyzed by the chi-square test.

The Combination of autologous PRF with the hydroxy apatite bioglass graft in the management of intra bony defects showed improved clinical and radiographic outcome.
Interdisciplinary management of horizontal root fracture in middle third with osseous bone defect – A clinical report
Authors: Srivastava Ruchi , Gautam Anju , Verma Pushpendra Kumar
Published: December 2023

Dental trauma are the main cause of emergencies in dental practice. Amongst these, root fractures are relatively uncommon but comprises about 0.5 to 7% of all injuries affecting permanent dentition. Most commonly, root fracture occurs from a horizontal impact mostly in oblique direction. The incidence is more common at the mid-third of the root rather at the apical and cervical thirds. Such hideous injury must be restored to normal as early as possible to retain the dental health and appearance. This report records the case of horizontal root fracture of upper anterior tooth, treated with Mineral Trioxide Aggregate (MTA) and fractured root fragments were unified with the aid of a stainless steel reamer after an endodontic treatment. Alloplastic bone graft and GTR membrane were used for osseous bone defect. Mineral trioxide aggregate (MTA) has several impending & forthcomin clinical applications owing to its grander sealing property and biocompatibility. A 12 months follow-up revealed a well stabilized assembly of the root fragments and periodontal healing.
Management of major recurrent aphthous ulcers with 5% amlexanox oral paste and rebamipide tablets- A case report with a brief literature review
Authors: Hasan Shamimul , Mohd. Faisal Siddique
Published: December 2023

Recurrent aphthous stomatitis (RAS) is a common chronic inflammatory oral mucosal disorder marked by the presence of painful, recurring ulcers, occurring either as solitary lesions or in multiple clusters. While the clinical features of this condition are easily recognizable, the precise etiology remains obscure. The disorder manifests in three forms, of which minor RAS are the commonest and heal within 10-14 days. Major RAS presents as larger, painful chronic ulcerations and heals with scarring in 6-8 weeks. A comprehensive medical history and a thorough systemic examination can aid the physician in determining whether the condition is idiopathic or linked to a underlying systemic disorder. The management of oral aphthous ulcers poses a significant challenge and there is no established and defined therapeutic regimen available for RAS.

We present a case of major RAS in a 37-year-old patient who was unresponsive to topical and systemic steroid therapy. 5% Amlexenox paste and rebamipide tablets were used in the present case. The patient showed favourable healing within a week therapy with no recurrences during the 6-month follow up.

Published: December 2023

Chronic periodontitis has been associated with many systemic diseases and many times chronic systemic diseases result in periodontal manifestations. An association between cardiovascular disease and periodontitis has been observed based on the current literature. The present case shows a rare finding of chronic periodontitis in a male patient as a result of an inflammatory disease of the blood vessel called Takayasu arteritis, which itself is a rare finding in a 31-year-old male patient. This case report attempts to highlight the role of diagnosis and understanding the etiology behind periodontal disease as a result of a rare systemic inflammatory disease, such as Takayasu arteritis.

Authors: Duarte Julio Enrique , Fernández Morales Flavio Humberto , Moreno Sereno Mauricio
Published: December 2023

La caracterización de dispositivos que modifican su estructura geométrica exige disponer de una técnica de medida precisa, fiable, eficiente y que se ajuste a los requerimientos experimentales. En este sentido, se ilustra el Interferómetro de Michelson como dispositvo para la medición de deflexiones en micromembranas de silicio actuadas termoneumaticamente. Se obtuvieron los anillos de interferencia debido a las modificaciones de la superficie de las membranas los cuales, al ser contabilizados, permiten establecer el comportamiento dinámico de la membrana. La estructura de prueba tiene un área de 4000 μm2, 14 μm de grosor y una cavidad de actuación con una profundidad de 300 μm.

LOS CUADERNOS DE JULIO GARAVITO UNA ANTOLOGÍA COMENTADA
Authors: Sánchez Clara H.
Published: December 2023

Julio Garavito Armero es sin duda uno de los más renombrados científicos colombianos del siglo XIX y comienzos del XX. Conocido como matemático y astrónomo, una buena parte de su obra publicada fue reproducida en la Revista de la Academia Colombiana de Ciencias cuando su primer presidente, Jorge Álvarez Lleras, su alumno, se propuso reproducir la obra de "científicos del pasado", entre los cuales se privilegió a Garavito. En el Observatorio Astronómico donde fue director desde 1891 hasta poco antes de su muerte en 1920 se encuentran una serie de cuadernos en los cuales existen algunos de los borradores de sus publicaciones, y de otros artículos que se quedaron inéditos, y estudios de temas de su interés en diversas áreas. Los temas que allí se encuentran son muy variados y en ellos podemos apreciar los múltiples intereses de Garavito y algunas de las notas que tomó de fuentes que se usó en sus cursos de cálculo infinitesimal y de mecánica analítica en la Universidad Nacional. Una antología del contenido de estos cuadernos es lo que hacemos en este trabajo.
MODELACIÓN NUMÉRICA DE EVENTOS TSUNAMIGÉNICOS EN LA CUENCA PACÍFICA COLOMBIANA - BAHÍA DE BUENAVENTURA
Authors: Restrepo Juan C. , Otero Luis J.
Published: December 2023

Se evaluó la amenaza por tsunami en el municipio de Buenaventura considerando diferentes escenarios de marea, magnitud y epicentro del sismo precursor. Los resultados indican que la variación de la magnitud del sismo precursor (Mw) genera cambios significativos en las áreas afectadas por inundación, y en la altura y tiempo de llegada del tren de olas. Un sismo de Mw= 8.6 produce un tsunami con alturas de ola superiores a 3.0 m., independientemente de la localización del sismo precursor. El tiempo de llegada del tsunami varía entre 56 y 92 minutos. Sin embargo, también se encontró que la configuración de la línea de costa y la morfometría de la bahía de Buenaventura reducen en un ~40% la altura del oleaje generado por un tsunami.
PSICOLOGÍA EN EL CONTEXTO DE LAS CIENCIAS NATURALES, COMPORTAMIENTO Y EVOLUCIÓN
Authors: Ardila Rubén
Published: December 2023

La psicología ha sido considerada a lo largo del desarrollo de la cultura occidental como el estudio de la psique, como el estudio de la mente y en el siglo XX y en el XXI como el estudio científico del comportamiento de los organismos. Se presentan los desarrollos de la psicología como área de conocimiento científico, a partir de 1879 con la fundación del primer laboratorio de psicología experimental en la Universidad de Leipzig (Alemania). Se señalan los dilemas que ha tenido que enfrentar la psicología, en lo que respecta a su objeto de estudio, su metodología, su inserción como ciencia natural y/o ciencia social, y la relación entre ciencia y profesión. Se enfatiza la importancia de utilizar un contexto evolutivo y el enfoque de ciencia natural. La investigación sobre “mente” y cognición animal y en general sobre el desarrollo filogenético de los procesos psicológicos, se presenta desde la perspectiva de la ciencia contemporánea.

Published: December 2023

El género Microtityus Kjellesvig-Waering, 1966 es un grupo de escorpiones que presenta un origen continental suramericano. Sus representantes actuales se conocen en gran parte de las islas del Caribe. En la porción continental suramericana este género se encuentra representado por un número menor de especies, distribuidas en Venezuela y Brasil. Recientes muestreos en la región Caribe de Colombia, permitieron detectar una población de Microtityus. Este nuevo hallazgo permite predecir que esta no es la única especie de Microtityus en Colombia, ya que muchas localidades en la región Caribe se encuentran sub muestreadas.
ON-GAUSSIANITY AND LOOP CORRECTIONS IN A QUADRATIC TWO-FIELD SLOW-ROLL MODEL OF INFLATION. PART I
Authors: Rodríguez Yeinzon
Published: December 2023

I am showing in this paper that it is possible to attain very high, including observable, values for the leve! of non-gaussianity f N L in a particular quadratic two-field slow-roll model of inflation with canonical kinetic terms. This is done by taking care of loop corrections both in the spectrum Pζ and the bispectrum Bζ; of the primordial curvature perturbation ζ. Sizable values for f N L arise even if ζ is generated during inflation. Five issues are considered when constraining the available parameter space: 1. we must ensure that we are in a perturbative regime so that the ζ series expansion, and its truncation, are valid. 2. we must apply the correct condition for the (possible) loop dominance in Bζ and/or Pζ. 3 we must satisfy the spectrum normalisation condition. 4. we must satisfy the spectral tilt constraint. 5. we must have enough inflation to sol ve the horizon problem.
HACIA UNA ONTOLOGÍA RELACIONAL DEL ESPACIO-TIEMPO
Authors: CalaVitery Favio Ernesto
Published: December 2023

En este artículo argumento --en contra de la opinión más generalizada--- que la Teoría General de la Relatividad recibe su interpetacíón natural como una teoría relacional sobre el espacio-tiempo. Para ello me apoyo en tres argumentos: i) La ausencia de identidad primitiva para los puntos del espacio-tiempo en teorías covariantes. ii)El hecho de que el tensor métrico, al tener una estructura genuinamente dinámica, se entiende mejor como un objeto material en toda regla. iii)La posibilidad tanto hipotética como concreta de formular alternativamente -en el contexto de la dinámica clásica- la geometría y la inercia como estructuras relacionales y no como estructuras intrínsecamente sustantivalistas.

Authors: Vargas Jiménez Carlos Alberto
Published: December 2023

Una evaluación sistemática sobre los diferentes estudios previos para estimar el potencial geológico asociado a los hidrocarburos convencionales en las cuencas sedimentarias de Colombia permite identificar un amplio espectro de resultados.

En este trabajo se presenta una síntesis de los rasgos sobresalientes de las cuencas sedimentarias, así como su potencial derivado de aproximaciones probabilísticas. Los resultados de OOIP para los percentiles P10 – P90 son del orden de 1.368.621,4 – 569.024,4 MBPE con un valor promedio de 930.758,8 MBPE. Bajo escenarios conservadores estos rangos con riesgo geológico máximo del 30% y factor de recobro máximo de 20% podrían sugerir un recurso prospectivo recuperable en el rango de 82.117,3 y 34.141,5 MBPE.

Published: December 2023

Los accidentes por mordeduras de serpientes venenosas producen más de 50 mil muertes al año, particularmente en los trópicos donde se han convertido en un problema de salud pública. Estos accidentes producen, entre otros síntomas, hemorragias (SVMPs), mionecrosis (PLAs) y dolor, y las seroterapias convencionales son solo parcialmente efectivas y pueden producir efectos inmunes adversos. Por todo esto, recientemente se están investigando proteínas antiveneno naturales de mamíferos [DM43 (antihemorragina) y DM64 (antimiotóxica) de la zarigüeya] que han demostrado ser más efectivas. Adicionalmente las SVMPs y PLAs venosas tienen sus contrapartes endógenas normales no venenosas (MMPs y PLAs), y cuando el balance entre estas últimas y sus inhibidores se rompe, se producen patologías como: artritis, arterioesclerosis, asma, diabetes, choques sépticos, neoplasias, inflamaciones, psoriasis, reumatismo, etc. Por todo esto se hizo una aproximación in silico y por homología a la estructura 3D de DM64, con el sistema Swiss Model-Deep View. Además de obtener un modelo similar al previamente logrado por otro grupo para DM43, este proceso permitió estandarizar esta técnica de modelamiento de proteínas como una herramienta muy útil en nuestro medio por su eficiencia y bajo costo (SM-DV se puede utilizar gratuitamente).

Se pudo observar ectoparásitos y endoparásitos que podrían afectar su sobrevivencia.
EVALUACIÓN RÁPIDA DE PECES ARRECIFALES Y SU RELACIÓN CON LA ESTRUCTURA DEL SUSTRATO EN LAS ISLAS DEL ROSARIO, ÁREA MARINA PROTEGIDA DEL CARIBE COLOMBIANO
Authors: Delgadillo-Garzón Oscar , Zapata-Ramírez Paula
Published: December 2023

Se evaluaron las comunidades de peces y se realizó una caracterización del sustrato arrecifal en las islas del Rosario por medio de censos visuales, para determinar la posible relación entre estas dos variables. Se registraron un total de 106 especies de peces y cinco unidades ecológicas de paisaje coralino (UEPC), con algunas diferencias entre las estaciones insulares y los bajos externos, debido a variaciones en la estructura del sustrato, factores ambientales e influencia antrópica. Los valores más altos de riqueza, abundancia y diversidad se encontraron en una combinación de las UEPC Corales mixtos (Cmix), Montastraea (Mon) y Octocorales-Corales mixtos (Oct-Cmix), observadas principalmente en el Bajo Tortugas. Una mayor investigación es necesaria para ampliar el conocimiento sobre la diversidad de peces en los ecosistemas costeros y los factores ecológicos que condicionan su distribución.

Authors: Restrepo L Juan Camilo , Otero D Luis , López I. Sergio A.
Published: December 2023

Para determinar el comportamiento del oleaje en el delta del río Mira se propagaron dos series de datos de oleaje (1979-2000) desde aguas profundas, la primera se obtuvo de la base de datos mundial de oleaje visual ICOADS y la segunda fue generada por medio del modelo de tercera generación Wave Watch III. Se estimó la altura del oleaje durante su tránsito hacia aguas someras después de sufrir los efectos de asomeramiento, refracción-difracción, disipación por fricción con el fondo y rotura del oleaje. Además, se obtuvieron datos de oleaje in-situ recolectados en el frente deltaico del río Mira utilizando un correntómetro AWAC ADCP (600 kHz). El clima de oleaje en aguas profundas se caracteriza por un oleaje proveniente del SW y SSW, con alturas significativas que se encuentran entre 0.29 y 2.23 m, y periodos pico que varían entre 5.0 y 23.0 s. Los procesos de refracción-difracción y asomeramiento ocasionan diferencias significativas en la altura de la ola de una región a otra, generando alturas superiores a 3.0 m en proximidad a la línea de costa cuando el oleaje incidente proviene del NNW y presenta periodos pico del orden de 18 s.

EL PERIODO CÁLIDO MEDIEVAL Y LA PEQUEÑA EDAD DE HIELO EN EL NEOTRÓPICO
Authors: García Castro Yuri Carolina , Martínez José Ignacio
Published: December 2023

En el Neotrópico existen registros paleoclimáticos marinos y continentales que sugieren la ocurrencia de condiciones relacionadas con el Período Cálido Medieval (MWP, ~800-1300 AD) y la Pequeña Edad de Hielo (LIA, ~1300-1800 AD). Sin embargo, la falta de sincronicidad en los eventos paleoclimáticos entre algunos registros (e.g. costeros y de los Andes), reflejan una respuesta geográfica variable al cambio climático. Se discuten aquí: (1) la complejidad de factores climáticos que modulan el clima tropical, (2) la diversidad de respuestas paleoclimáticas, (3) el sesgo debido al escaso número de registros paleoclimáticos en el Neotrópico, (4) las limitaciones de los métodos de datación y, (5) los impactos de los eventos del MWP y la LIA a escalas regionales. Finalmente sugerimos áreas prospectivas para futuros estudios.
Managing Diversity and Inclusion in Nursing Homes: Practices and Regulations
Authors: Lindheim Tone
Published: December 2023

Changing demographics and a rising number of immigrants entering the labor market have posed new challenges to managers in work organizations.Within this context, Norway has been noted to have a highly regulated work sector that is considered beneficial for minorities and marginalized groups.  Through a case study of three nursing homes in Norway, this paper analyzes how managers engage with diversity-related regulations when addressing their everyday challenges, and how their enacted practices affect the inclusion of immigrants in the workplace. The study applies a practice-theoretical approach and contributes to diversity management research by identifying how managers’ differing enactments of inclusion-related practices are connected to competing institutional logics. The analysis shows how the co-existence of multiple institutional logics in this context represents an arena for political struggle.

Published: December 2023

Spontaneous paracentesis is a life-threatening complication of liver cirrhosis. Importance of precise and early identification cannot be overstated, as early treatment improves the prognosis and survival. A 78-year-old woman with cirrhosis presented with ascitic fluid gushing out from an umbilical hernia. The patient received intravascular repletion with intravenous albumin, antibiotics, and rapid umbilical herniorrhaphy. Post-operatively, the patient experienced acute kidney injury and portal vein thrombosis, which was corrected with electrolyte replacement and transjugular intrahepatic portosystemic shunt with thrombectomy. The patient recovered completely and was discharged without difficulty.
Dynamic Power Consumption in Base Transceiver Station in Urban and Rural Setting in Awka, Nigeria using Multi-Attribute Decision-Making Technique
Authors: C.S. Okafor , V.N. Okorogu,
Published: December 2023

The goal of this paper was to lower base transceiver station (BTS) dynamic power consumption. A multi-attribute decision-making technique was implemented that reflects the stochastic nature of cellular networks and guarantees cost-effective traffic generation and improved BTS power consumption performance. Every related candidate or attribute that is taken into consideration to help reduce power consumption is given a utility function, and the candidate with the highest utility value is chosen to meet the target. The Utility function that the Technique selects is the weighted sum of the normalized attributes. In contrast to the works of other authors, which lowered consumption by 20%, the developed dynamic power consumption model cut consumption to 25.14 percent. The two BTS of interest were measured, and the results showed that Mgbakwu BTS has two Peak (Busy) Hour periods: in the morning, 9.55Erlangs from 7.30am to 8.30am, and in the evening, 10.7Erlangs from 8.30pm to 9.30pm. The BTS is located in a rural/residential area. The BTS measurement and analysis for the UNIZIK temporary site revealed that it is located in a commercial/business setting with a morning peak (busy) hour period of 19.1 Erlangs between 10 and 11 a.m. 14.6 Erlangs is the afternoon peak hour, which runs from 3.30 to 4.30 p.m. The traffic generated in the BTS under various load situations is reflected in the relevant Power Consumption for both BTS.
Evaluation of the performance of the internal audit function in Libyan banks: A study on Libyan commercial banks.
Authors: Abdoullah Omar Ikryim Ali , Boumedien Prof. Emna
Published: December 2023

This study aimed to evaluate the performance of the internal audit function in Libyan banks and to explore the role of demographic information in determining this evaluation. It provides an insightful look into the performance and this relationship through the opinions of the respondents. The study utilized a quantitative descriptive-analytical approach to collect data and answer the posed questions. The study population consisted of employees in the Libyan commercial banking sector. The study distributed 350 questionnaires to Libyan banks, and after about three weeks, 345 were collected, of which 333 were valid for analysis. Survey results indicated that respondents largely agreed that the performance of the internal audit function was high, as most scores were rated high. However, there were some items that respondents indicated as average, meaning they did not agree with their content. Hence, it should be noted that internal auditing should provide recommendations to improve the internal control system when necessary, tables of committee meeting agendas and related key information should be circulated before meetings, and the audit committee should monitor the selection of accounting policies and principles. The study also revealed that there was no statistically significant effect of demographic information on the evaluation of the performance of the internal auditor, with the exception of the age variable. Thus, the study recommends addressing the challenges faced in adopting the International Financial Reporting Standards (IFRS) by providing a high-quality set of internationally recognized accounting standards that achieve transparency, accountability, and efficiency for financial markets worldwide.
A Qualitative Study of Disability in Minority Veterans and Their Utilization of the VA Health System
Authors: Aristide Gibson
Published: December 2023

Over time, as the United States army increased, white and minority citizens joined the military forces. This led to the establishment of the Veterans Bureau, and later the Veterans Administration, to care for the wounded soldiers. Although the nation had developed a system to provide services to veterans since the late 1700s, there has been a decline in utilization of y veteran service members in the modern day. The purpose of this phenomenological study is to investigate the causes behind the limited use of the mental health services provided by the VHA by minority veteran service members and to propose ways to improve these services. Additionally, another purpose was to examine any cases of discrimination against minority veteran service members based on interviews with participants and previous empirical literature. After conducting multiple interviews, the status of patient satisfaction, degree of reliance on VHA medical facilities, perception of efficiency of services, and patronage XIII were analyzed. In summary, previous empirical literature had indicated that minority veteran service members were more likely to face discrimination because of racial bias. However, today, that is not largely the case. Rather, most of the minority veteran service members interviewed did not face discrimination and they were content with the health services offered. While some of the interviewees did claim that they faced some acts of discrimination, the overwhelming majority did not. These findings suggest that most minority veteran service members do not face discrimination and that they are actively interested in seeking VH healthcare services. Nevertheless, understanding minority veteran service members may enable healthcare providers to provide them with customized healthcare sections.

Caractéristiques Dendrométriques de Boscia Senegalensis (pers.) Lam. Ex poir et Variabilité Morphométrique de ses Fruits Suivant la Toposéquence dans la Zone Nord du Ferlo (Sénégal)
Authors: Cissé Khady , Diatta Sékouna , Sagna Moustapha Bassimbé , Diallo Rabiyatou
Published: December 2023

L'objectif de cette étude est d'évaluer la variabilité morphométrique des fruits et de la population de Boscia senegalensis en fonction de la toposéquence (plateau, versant et bas-fond) dans la région du Ferlo, au nord du Sénégal. Quinze individus de l'espèce ont été choisis au hasard, cinq par niveau topographique. Des mesures ont été effectuées sur les paramètres dendrométriques (hauteur et diamètre du houppier) des individus et sur les descripteurs morphométriques des fruits (diamètres transversaux du fruit et de la graine et nombre de graines, longueur du pédoncule, masses du fruit, de l'épicarpe et de la pulpe visqueuse). L'analyse en composantes principales et l'analyse factorielle discriminante ont montré l'existence d'une variabilité morphométrique des fruits en fonction du niveau topographique, ce qui n'est pas le cas pour le nombre de graines par fruit. Aucune corrélation n'a été observée entre les deux types de descripteurs évalués (<20%). Par contre, les variables fruits, fortement corrélées avec les unités topographiques (>50%), contribuent significativement à l'explication des variabilités observées. En effet, la pente est plus favorable au développement du pédoncule (1,30cm) et à la croissance du poids des fruits (2,33g et 1,23g) alors que la plaine est plus favorable au développement des dimensions des fruits (15,38mm et 16,75mm). L'étude a montré l'existence de morphotypes chez les individus de l'espèce en fonction de la toposéquence. Les résultats de cette étude pourraient être utiles dans le cadre d'un programme de sélection variétale et d'amélioration génétique de l'espèce, mais aussi pour sa conservation et son utilisation durable au Sahel.

Published: December 2023

Blighia sapida est une espèce très domestiquée au Bénin et dont les fruits riches sur le plan nutritionnel sont utilisés pour des raisons alimentaire, phytothérapeute et cosmétique. Malgré son niveau de domestication, l’espèce se trouve aujourd’hui dans une situation de régression progressive dans les agro-forêts. Les causes majeures pourraient être la sélection de provenances moins performantes et l’usage des semences de mauvaises qualités dues à la viabilité très limitée dans le temps des graines de Blighia sapida si elles ne sont pas bien conservées. Face à ce fléau, au fil des générations, les communautés locales ont développé des connaissances endogènes sur des techniques de conservation moins couteuses ayant révélé leurs utilités dans le processus de régénération de l’espèce. Cette étude a porté sur la caractérisation des traits morphologiques des graines de Blighia sapida, ses pratiques de conservation et de dissémination suivants les régions agro écologiques du Bénin. Pour cela, il a été procédé à la sélection dans chaque phytodistrict, des arbres sur lesquels des fruits murs ont été récoltés puis mis en sachet étiqueté et conservé dans un sac glacière muni de gels réfrigérants. Avec l’usage d’un pied à coulisse et d’une balance électronique de précision, les paramètres morphométriques ont été collectés sur les graines extraites des fruits. Les résultats obtenus ont montré qu’au Bénin, sur le plan statistique, il n’y’a pas de variabilité significative des graines entre les provenances étudiées. Cependant, la provenance nord a obtenu les meilleurs résultats sur le poids (59,36 g ± 14,68), l’épaisseur (16,136 mm ± 2,671) et la largeur (20,658 mm ± 2,965) des graines. Ces dernières récoltées en saison sèche, peuvent être conservées au soleil, à la température ambiante ou au frais pour une durée comprise entre 10 et 30 jours. D’après les communautés locales, B. sapida se régénère naturellement (82,5%) ; néanmoins la multiplication par semis de graines (17,5%) se pratique le plus souvent au nord du pays. A la sortie de cette étude, il s’avère indispensable d’élargir ces activités à toutes les zones agro-écologique du Bénin afin de pouvoir affirmer ou infirmer ces informations et de pouvoir sélectionner une meilleure semence qui sera destinée aux programmes de développement.

Mobile devices such as smartphones, tablets, iPads, and laptops have become increasingly used in the workplace, bringing new cybersecurity challenges to organizations where they have been connected to the company's network. Bring Your Own Devices (BYOD) practice, which allows employees to use their personal devices for work purposes from anywhere and at any time. Although BYOD offers benefits, it also has drawbacks in the workplace. So, its adoption is a source of concern. This study's objective is to know which of the fourteen BYOD potential security concerns mentioned in the questionnaire were faced before by the IT department staff and how they ranked these BYOD potential security concerns depending on their experience from low to very high. A descriptive methodology was employed in this study. A questionnaire was used to collect data from forty people in the IT department at Aden Refinery Company. The results show that some BYOD potential security concerns have been faced by all the staff in the IT department, for instance (viruses and malware infections). Also, the results indicate that organizations need to create more awareness regarding BYOD security due to the IT department staff having faced more than one of the BYOD potential security concerns.
Notary’s Liability for the Cancellation of the Deed of Establishment of A Foreign Investment Limited Liability Company due to Violation of the Notary Profession

Published: December 2023

AbstractThe need for notary services, especially in terms of the preparation of deeds of establishment of limited liability companies is increasing, along with the rapid development of the business world, which is also supported by the development of information technology. The establishment of a limited liability company according to Article 7 paragraph (1) and paragraph (2) of the Limited Liability Company Law, is based on an agreement between 2 (two) or more persons, by obliging each founder to take a share and stated before a Notary in a deed of establishment in Indonesian language containing the company's articles of association. In addition to requiring a deed of establishment, the establishment of a limited liability company also requires capital. The capital can come from domestic or foreign/foreign sources. Therefore, the type of limited liability company based on the type of capital is divided into 2 (two), namely Domestic Capital Limited Liability Company (PMDN) and Foreign Capital Limited Liability Company (PMA). The type of research in this legal research is normative or doctrinal legal research conducted by examining secondary data consisting of primary legal materials, secondary legal materials, and tertiary legal materials. In practice, problems sometimes arise, especially in Limited Liability Foreign Capital Companies (PMA), as in the case decided by the Denpasar District Court Decision Number: 485/Pdt.G/2015/PN.Dps. The Panel of Judges of the Denpasar District Court decided that Deed No. 52 concerning the Establishment of PT Mexicano Asia made before Notary I Putu Chandra, S.H., was declared null and void.Keywords: deed cancellation, notary; limited liability company establishment; foreign investment.

Patients with cancer are at risk of death. There has been a lack of research on cancer-related training for health cadres. Meanwhile, they can potentially prevent cancer deaths because of their proximity to the community. This study aimed to determine the effectiveness of cancer educational videos on cadres’ knowledge and self-efficacy in Yogyakarta. This was quasi-experimental research with a nonequivalent control group design. The purposive sampling technique was used to obtain data from 61 health cadre respondents. The inclusion criteria: older than 19 years old, a woman, and uses WhatsApp. The Cancer Knowledge and General Self-Efficacy Scale Questionnaires measurement instruments were used. Data analysis was conducted using an independent sample t-test, repeated ANOVA, and paired comparison post hoc. There was a significant difference in respondents' knowledge in the control and intervention groups (p<0.05). The intervention group’s knowledge increased, and there was a moderate increase in knowledge in the control group. There was no significant change in cadres’ self-efficacy in the intervention group (p>0.05), but there was a significant increase (p<0.05) in the control group. Therefore, cadres’ training using cancer educational videos is effective for increasing cadres' knowledge only and not self-efficacy.

The synthesis of anethole-lauryl methacrylate (LMA) copolymer had been carried out by cationic polymerization using BF3O(C2H5)2 as the initiator without the use of solvent at room temperature (28-30 °C) over atmospheric N2 conditions. Polymerization was conducted by varying LMA concentration i.e. 2%, 4%, and 6%, (w/w) with respect to the anethole weight. Structural determination of co-poly(anethole-LMA) was done using FTIR and 1H-NMR spectrophotometer. The relative molecular weight (Mv) of co-poly (anethole-LMA) was measured by an Ostwald Viscometer at room temperature. Morphological characterization and surface area analysis of co-poly(anethole-LMA) was performed using SEM and SAA, respectively. The successful synthesis of co-poly(anethole-LMA) was proven by the disappearance of vinyl group absorption at 1696, 1638, 965, and 938 cm-1 of the FTIR spectra, as well as the loss of vinyl group proton signals at 6.4-5.5 ppm in the 1H-NMR spectra. Increasing the weight of the LMA affected the characteristics of co-poly(anethole-LMA). The relative molecular weight of co-poly(anethole-LMA) was found to rise by increasing the weight of LMA. The Mv of co-poly(anethole-LMA) 2%, 4%, and 6% were 32378.62, 50611.05, and 65133.79 g/mol, respectively. The morphology of co-poly(anethole-LMA) showed that the surface distance between particles was getting tighter and the highest surface area in co-poly(Anethole-LMA) 6% was 233.80 m2/g.

Ketoprofen is a medicinal compound derivative of phenyl alkanoic acid that works as an anti-inflammatory, antipyretic, and analgesic. In the Biopharmaceutical Classification Systems, ketoprofen is a class II drug with high permeability but low solubility. Due to its low solubility, the absorption and bioavailability of ketoprofen are very limited, which can affect its therapeutic effectiveness. This study aimed to increase ketoprofen's solubility by forming multicomponent solids using 2,5-dihydroxybenzoic acid coformer with adding hydrophilic polymers ((hydroxypropyl)methylcellulose, polyvinylpyrrolidone K90, and polyethylene glycol 4000). The results showed that ketoprofen with 2,5-dihydroxybenzoic acid coformer prepared using the solvent evaporation method formed a eutectic mixture. Adding hydrophilic polymers to the ketoprofen - 2,5-dihydroxybenzoic acid multicomponent solid increased the crystallinity and decreased the melting point of the multicomponent solids. The multicomponent solids of ketoprofen - 2,5-dihydroxybenzoic acid with the addition of hydrophilic polymers had solubility and dissolution efficiency significantly higher (p<0.05) than the ketoprofen - 2,5-dihydroxybenzoic acid multicomponent solids without hydrophilic polymers.

Published: December 2023

Beta-casein in milk is known to be a bioactive peptide producer because of its amino acid sequence. Bioactive peptides have prospected molecules that can adhere with SARS-CoV-2 spike protein, so they can inhibit the virus from hooking up with human cell receptor protein. The research is aimed to find any peptides from goat’s milk beta-casein that are prospective candidates as SARS-CoV-2 spike protein inhibitors. Goat’s milk beta-casein was simulated as being digested by the digestive tract. Pepsin, trypsin, and chymotrypsin enzymes cut the beta-casein amino acids sequence into small peptides. Then, their bioavailability was predicted by Lipinski’s Rules of 5 (Ro5), any most fitted peptides to the rules will be simulated to dock to SARS-CoV2 spike protein besides Curcumin as the control ligand. Peptides with the best bind activity with the spike protein will be selected as inhibitor candidates. Peptide QPK is selected as a SARS-CoV-2 inhibitor candidate because it has better affinity energy than Curcumin or other selected peptides.

Published: December 2023

This research studied kinetics of thermal degradation of polystyrene (PS), and sulfonated polustyrene (sPS) which were synthesized from styrofoam waste. The thermal study was conducted by thermogravimetric analysis (TGA) at various  heating rate of 10, 15, 20 and 25 dpm. The kinetics parameters were determined by Coats Redfern (CR), Friedman (FM), Kissinger-Akahira-Sunose (KAS) and Ozawa-Flynn-Wall (OFW) models. TGA result found that PS has range thermal stability of 274 – 415 oC, but sPS has range thermal stability of 175 – 582 oC. Kinetic study to PS shows that the activation energy increases by the increasing of fraction conversion for all kinetics parameters with a regression value close to 1. While in sPS, the CR method shows an increase in activation energy value with an increasing fraction convertion. On the other hand, CR-FM-KAS and OFM methods obtained an increase in activation energy, then decreased at the fraction convertion above 0.6, and received negative activation energy. The kinetics model successfully explains the degradation of PS and sPS. In addition, the high thermal stability of sPS from styrofoam waste shows that this material has good potential as polymer electrolyte materials.

The significance of cholesterol and ergosterol (provitamin d2) in biological systems has prompted interest in these compounds as pharmaceuticals. It has been reported on the effective straightforward synthesis of Schiff base modifications of cholesterol aldehyde and ergosterol aldehyde and their assessment as possible agents against cancer (esophagus natural cell lines and human cancer cells). Through a process called Steglish esterification, the initial cholesterol and ergosterol are converted into their respective aldehyde derivatives, by reacting with amines such as 2-amino 6-fluoro benzothiazole, carbohydrazide, and thiosemicarbazide, these aldehyde derivatives are transformed into the appropriate Schiff base derivatives, and then their anticancer activity is checked using the MTT (Microculture Tetrazolium Assay) assay method. For the purpose of analyzing their cytotoxic effects, these compounds were tested on cancerous (SK-GT-4, human esophageal adenocarcinoma) and normal (normal cell line, Rat Embryonic fibroblast (REF)) cell lines. The MTT assay results revealed that the compounds (a1, a2, c1, c2, compound 1) were more harmful to human esophageal cancer cell line than to healthy cell line other than compounds (t1, t2, compound 2, ergosterol and cholesterol alone). Overall, our research indicated that provitamin D2 (ergosterol), a1, a2, c2, t2, compound 1, had a growth-inhibiting effect on both cell lines compared to c1, t1, compound 2, and cholesterol alone.
