Des terroristes au nom du Jihâd ! Et pourquoi pas une fonction β au service d‘éléments bêta ?
Authors: Papazian Berdj
Published: October 2023

La montée des fondamentalismes et des attaques terroristes islamistes donne en ce moment de la fièvre au monde occidental. Une hypothèse strictement psychanalytique pourrait rendre compte d’une partie de ce phénomène sociopolitique. L’auteur s’appuie sur les théories du premier Bion pour cerner le fonctionnement psychique des jeunes radicalisés qui rejoignent le Jihâd. Quelque soit leur extraction sociale, ces recrues se caractérisent peu ou prou par un trouble identitaire narcissique. W. R. Bion nomme les impressions sensorielles qui ne sont pas intégrées « éléments bêta » et « écran-bêta » l’accumulation de ces émotions brutes qui ne cherchent pas qu’à s’évacuer mais aussi à se lier. L’« écran-bêta » génère tantôt une hallucinose, tantôt une confusion mentale, toutes deux défensives d’angoisses d’annihilation. C’est surtout dans ce deuxième cas que leur évacuation par identification projective pathologique échoue même à soulager les sujets dont l’esprit sature d’éléments bêta. Une idéologie sectaire de type État Islamique peut offrir une solution attrayante à ses états confusionnels sous forme de contenant d’écrans-bêta, quitte à attiser des passions identitaires. C’est la fonction β proposée par l’auteur, une fonction de liaison rassemblant des appareils psychiques gouvernés par la déliaison. Contrairement à la fonction α, la fonction β ressortit au fonctionnement de groupe et sert la pulsion de destruction.
Les flottements identitaires dans l’informé de la cure
Authors: Boucherat-Hue Valérie
Published: October 2023

Dans les cliniques contemporaines de l’informe , qui gagnent à ce que soit repris dans le setting analytique le vécu corporo-psychique primitif, se fait sentir la nécessité d’aménager le dispositif psychanalytique classique. Il s’agit d’une part de mobiliser le processus précisément au niveau ultra-régressif qu’il appelle dans ces pathologies de l’excitation, et d’autre part d’encadrer fermement la régression par la butée perceptive. Seront proposés deux fragments de travail clinique avec des patients aux lourdes fragilités narcissiques-identitaires mais sans psychose organisée, pour lesquels une psychothérapie sensoripsychique d’orientation psychanalytique a été engagée. Inspirée du dialogue sensorimoteur et tonico-émotionnel de J. de Ajuriaguerra avec les enfants, et du travail d’énaction de S. Lebovici avec les bébés, cette approche facilite avec les adultes les mouvements de liaison psychocorporelle. C’est une médiation qui repose sur l’attention conjointe et soutenue aux infimes états du corps du patient en séance et sur leur mise en forme figurative dans le travail associatif de co-pensée. Elle s’appuie sur l’élaboration par l’analyste des co-sentis qui traversent son contretransfert-sensoriel, ce dernier servant d’incubateur au travail de transformation psychique qui précède la traduction interprétative faite aux patients.
L’enfant donneur ou le sublimateur du genre : un transfert prématurément interrompu

Published: October 2023

Désireux de s’émanciper de la maltraitance clinique ainsi que de l’arrogance théorique à l’égard d’une population aux identifications de genre atypiques, l’auteur de cet article se propose de restituer son expérience, ses épreuves et ses doutes, à partir de l’écoute offerte par un adulte confronté aux problématiques transidentitaires. Il aborde ainsi dans une perspective interactionniste les enjeux intrapsychiques et les normes socioculturelles qui participent à la souffrance du patient suivi en institution, ainsi que les fragilités du/de la thérapeute et les obstacles contretransférentiels qu’il/elle rencontre.
L’hallucination négative dans la clinique
Authors: de Vriendt-Goldman Claire , Faoro-Kreit Blandine , Lecoq Arlette
Published: October 2023

Cet article a pour intention d’approcher la pluralité du concept d’Hallucination négative élaboré par A. Green par des illustrations puisées dans nos situations cliniques. L’Hallucination négative présente deux pôles, le structurel et le défensif. Il y a celui qui œuvre à la création de la structure encadrante, assise du narcissisme primaire et matrice des représentations et identifications futures, et celui qui préside à l’effacement, plus ou moins drastique, des perceptions inconciliables ou insupportables pour le psychisme. Elle contribue de la sorte à l’économie pulsionnelle de la psyché depuis le commencement.
Improved results for testing the oscillation of functional differential equations with multiple delays
Authors: Essam Amira , Moaaz Osama , Ramadan Moutaz , AlNemer Ghada , Hanafy Ibrahim M.
Published: October 2023

In this article, we test whether solutions of second-order delay functional differential equations oscillate. The considered equation is a general case of several important equations, such as the linear, half-linear, and Emden-Fowler equations. We can construct strict criteria by inferring new qualities from the positive solutions to the problem under study. Furthermore, we can incrementally enhance these characteristics. We can use the criteria more than once if they are unsuccessful the first time thanks to their iterative nature. Sharp criteria were obtained with only one condition that guarantees the oscillation of the equation in the canonical and noncanonical forms. Our oscillation results effectively extend, complete, and simplify several related ones in the literature. An example was given to show the significance of the main results.
Effect of the Degree of Filling on Mechanical Properties of Polymeric Specimens from Polyethylene Terephthalate Glycol and Polylactic Acid Produced by 3D Printing
Authors: Dantas Gabriel Da Motta , dos Santos Danielle Ferreira
Published: October 2023

Based 3D printing has become very popular in recent years due to the emergence of projects for low-cost machines, making the technology very accessible. In view of this, some polymers, in general, in thermoplastic filaments, are placed on the market for application in this type of printing technique, making it increasingly necessary to develop research for the characterization of materials to provide information on physical, thermal and mechanical properties. For the development of this work, the polymer poly(ethylene glycol terephthalate) (PETG) was used for a comparative study in relation to poly(lactic acid) (PLA). PETG is obtained by adding modified glycol to the material composition during the polymerization process. It consists of a polymer with a glass transition temperature close to 80°C, with mechanical properties similar to those of PET, with the advantages of notable tenacity, flexibility, and high processing capacity, and PLA is a polymer synthesized from corn sugar, potatoes, and sugar cane, through bioconversion and polymerization. PLA presents biocompatibility, biodegradability, and biological absorption, presenting good mechanical properties, processability, thermal stability and low environmental impact. Mechanical tests of compressive strength and flexural strength were carried out. In the compressive strength test, the specimen with 100% filling presented a deformation 76% greater than the specimen with 50% filling. This can be attributed to the mechanical property of the PETG polymer, as it is very ductile, thus facilitating the processability of this artifact. The mechanical flexural strength tests carried out with the PLA polymer with the highest filling percentages (100% and 50%) showed less deformation until failure, characterizing them as more ductile materials. On the other hand, specimens with 30% filling showed ~215% greater deformation than specimens with 100% filling. With this, it can be seen that PLA has greater flexibility and tenacity for fillings of low percentages, due to the internal spacing absorbing the impact of loads. The PLA polymer showed better mechanical properties, such as Young's modulus, ductility and more satisfactory resistance when compared to the PETG polymer. As well as the synthesis of PLA, it characterizes the process in a more sustainable way, as it is a biopolymer, in addition to its excellent processability.

Authors: Lorenzo John Kristoffer , Andal Alexander Romig , Morales Aldwin Jeffrey , Davantes John Joshua , Taguba Manny Anthony M.
Published: October 2023

Concrete is recognized as the most commonly used man-made material in the world. But because of all the modern developments in the building industry, this leads to compromises that worsen the environment. The third-largest source of anthropogenic CO2 emissions in the world is the cement sector. Alternately, cement-like substances known as geopolymer concrete could be produced from pozzolan material. A form of concrete known as geopolymer concrete uses silica and aluminum-rich geopolymeric elements in place of cement entirely. This new technology is gaining popularity, offering a more environmentally friendly alternative. This study focuses on characterization of coconut husk ash using Scanning Electron Microscopy (SEM) coupled with Energy Dispersive Spectroscopy (EDS), and Fourier Transform Infrared (FTIR) Spectroscopy in order to investigate its efficiency as a potential substitute for fly ash in geopolymer concrete.
The Study of Velocity Field in Front Opening Unified Pod by CAE
Authors: Lin Yao Tsung , Hwang Shyh Shin , Zhu Jun An
Published: October 2023

The front opening unified pod (FOUP) is a packing box for contamination control for semiconductor wafer transport. As the wafer fabrication process developes towards nanoor atom level, the semiconductor wafer storage device should advance from the particle prevention function into the airborne molecular contamination (AMC) removal function. Therefore, it is necessary to design/redesign a function for removing AMC or moisture inside the FOUP. This study used the design of leading diffuser tubes in the FOUP and pores in the surfaces of diffuser tubes to generate gas diffusion. This is to achieve a uniform distribution of the wafer surface velocity field and a uniform dehumidification function of the wafer surface. Based on the analysis results, when circular diffuser tubes are introduced in the FOUP and the intake air flow was set at 0.2-0.3 m3/hr, the interlayer wafer surface in the FOUP could achieve uniform distribution of velocity field. As a result, the humidity difference among various zones of wafer surface could be reduced, and the yield and quality of the wafer cutting process could be controlled.
Unmanned aerial vehicle and proximal sensing of vegetation indices in olive tree (Olea europaea)
Authors: Roma Eliseo , Catania Pietro , Vallone Mariangela , Orlando Santo
Published: October 2023

Remote and proximal sensing platforms at the service of precision olive growing are bringing new development possibilities to the sector. A proximal sensing platform is close to the vegetation, while a remote sensing platform, such as unmanned aerial vehicle (UAV), is more distant but has the advantage of rapidity to investigate plots. The study aims to compare multispectral and hyperspectral data acquired with remote and proximal sensing platforms. The comparison between the two sensors aims at understanding the different responses their use can provide on a crop, such as olive trees having a complex canopy. The multispectral data were acquired with a DJI multispectral camera mounted on the UAV Phantom 4. Hyperspectral acquisitions were carried out with a FieldSpec® HandHeld 2™ Spectroradiometer in the canopy portions exposed to South, East, West, and North. The multispectral images were processed with Geographic Information System software to extrapolate spectral information for each cardinal direction’s exposure. The three main Vegetation indices were used: normalized difference vegetation index (NDVI), normalized difference red-edge index (NDRE), and modified soil adjusted vegetation index (MSAVI). Multispectral data could describe the total variability of the whole plot differentiating each single plant status. Hyperspectral data were able to describe vegetation conditions more accurately; they appeared to be related to the cardinal exposure. MSAVI, NDVI, and NDRE showed correlation r =0.63**, 0.69**, and 0.74**, respectively, between multispectral and hyperspectral data. South and West exposures showed the best correlations with both platforms.
Evaluation of Vitamin D level in thalassemia patients: The experience of a single center
Authors: Al-Rubae Alaa M. , Ansaf Ahmed I. , Faraj Safa A.
Published: October 2023

BACKGROUND:

Beta-thalassemia, a hereditary blood disease transmitted through families, has become increasingly relevant with rising life expectancies, leading to bone disease being a significant cause of morbidity. Among the symptoms observed in these patients, bone pain and back pain are frequently reported. Vitamin D is believed to play a crucial role in reducing these symptoms.

AIM:

The objective of this study was to assess the Vitamin D levels in thalassemic patients and investigate potential correlations with other factors.

PATIENTS AND METHODS:

A cross-sectional study was conducted, involving a random selection of 48 patients with beta-thalassemia (major and intermediate types) aged 7 years and above. The patients were registered at the Hereditary Blood Disease Center in Wasit province, located in the South of Iraq, during the period from January to May 2022. Demographic data, including age, sex, address, diagnosis, type of chelation therapy, and frequency of blood transfusions, were collected from patients’ files. Biochemical data, such as mean hemoglobin, mean serum ferritin, mean serum calcium, and Vitamin D levels at the time of the study, were also recorded. Vitamin D levels below 30 ng/ml were considered low level or deficiency, whereas 30 ng/ml and above were considered normal, as indicated by the kit manufacturer. Furthermore, the height, weight, and body mass index were evaluated in the studied patients with their written consent. SPSS version (23) was employed for data management and statistical analysis, utilizing a significant P = 0.05 and the Pearson’s correlation.

RESULTS:

The study revealed that 42 patients (87.5%) had low Vitamin D levels (below 30 ng/ml). The mean Vitamin D level was 18.23 ng/ml, with a maximum reading of 45 ng/ml. It was observed that Vitamin D deficiency was more prevalent in younger patients and those with higher ferritin levels, although the differences were not statistically significant.

CONCLUSION:

Vitamin D deficiency is common in patients with B-thalassemia, as indicated by this study.
99mTechnetium-Ubiquicidin Scan with Single-Photon Emission Computed Tomography/Computed Tomography in Skull Base Osteomyelitis
Authors: Vatakara Arunraj , Damle Nishikant Avinash , Khurana Aditi , Sagar Sambit , Kumar Rajeev , Verma Hitesh
Published: October 2023

Malignant otitis externa (MOE) with skull base osteomyelitis (SBO) is an aggressive infection that predominantly affects elderly, diabetic, or immunocompromised patients, and is associated with high disease-specific mortality. Pseudomonas aeruginosa is the most isolated microorganism. External otitis associated with granulation tissue and pain is the most common presenting feature; a biopsy is obtained to rule out malignancy. A proper consensus is lacking regarding the best imaging modality for early initial diagnosis and follow-up. 99mTechnetium (99mTc)-labeled ubiquicidin (UBI) 29–41 is a bacterial attaching peptide that does not bind to activated leukocytes. We report a case of SBO initially misdiagnosed as a chronic otitis media, but later proved to be a case of MOE. 99mTc methylene diphosphonate bone scan and 99mTc-UBI 29–41 scan with single-photon emission computed tomography/computed tomography scans were performed to corroborate the clinical diagnosis. SBO remains a great challenge due to its increasing prevalence and high morbidity are difficult to diagnose and are often confused with cholesteatoma and neoplastic process. The UBI scan could be an auxiliary noninvasive diagnostic alternative in early diagnosis.
Tc-99m MDP Scan with Unusual and Isolated Skeletal Metastasis in Skull Bone in a Case of Testicular Seminoma
Authors: Jain Sanchay , Singh Deepa , Jain Suruchi
Published: October 2023

Seminomas are common germ cell tumors (GCT) that may arise in the testes as well as in extra testicular locations such as mediastinum with/without testicular tumor. Testicular tumors are usually detected early due to their location and presentation as testicular mass. The overall prognosis of the seminomatous GCTs is good with surgery as the mainstay of treatment in localized disease. Bone metastases, especially when present in isolation are exceedingly rare in seminoma. Here, we present a rare case of skull bone metastasis in a case of testicular seminoma which was detected on technetium-99m labeled methylene diphosphonate bone scintigraphy with single-photon emission computed tomography with computed tomography.

A 67-year-old man is presented with complaints of chest pain and productive cough for 1½ years. Chest X-ray was suggestive of right upper lobe Koch’s lesion. Sputum was positive for mycobacterium tuberculosis. His symptoms got relieved partially by antitubercular treatment but the patient had an aggravation of symptoms for which he was evaluated. Computed tomography (CT) thorax revealed an endobronchial lesion in the right upper lobe bronchus. Bronchoscopy showed a mass in the right main bronchus and biopsy was suggestive of moderately differentiated squamous cell carcinoma (SCC). 18Fluoro-deoxy-glucose positron emission tomography/CT was performed for staging. There would have been chances of coexisting tuberculosis with SCC.

Authors: Konsam Meena , Praharaj Samir Kumar , Panda Sunita , Shetty Jyothi , Ravishankar N. , D’Souza Sonia R. B.
Published: October 2023

Background:

Pregnant women experience increased sleep disturbances during the third trimester of their pregnancy, which may result in the development of psychological issues in the perinatal period. There is a dearth of interventional studies that combine health literacy and the provision of music for the benefit of pregnant women in South Asia.

Aim:

To determine the effectiveness of a combination of Comprehensive Health literacy And Relaxing Music (CHARM) interventions on quality of sleep and risk for antenatal depression among women visiting antenatal outpatient departments of a tertiary hospital in South India.

Methods:

A four-arm parallel-group randomized controlled trial was adopted; 128 low-risk primigravid women were recruited and randomly assigned to the four groups using block randomization. The interventions included relaxing music interventions, comprehensive health-literacy interventions, combinations of both as CHARM interventions, and standard antenatal care. All the interventions were provided for four weeks. The quality of sleep among pregnant women was assessed using the Pittsburgh Sleep Quality Index Scale at baseline and after four weeks of intervention. Women at risk of developing antenatal depression were screened using the Edinburgh Postnatal Depression Scale-Antenatal Version.

Results:

Pregnant women who received CHARM interventions had significant improvement in quality of sleep when compared with other interventions (F
(3,124) =15.0, P < .001, effect size η
p
2
= 0.27). Also, 38 (29.6%) of the included pregnant women were at risk of developing antenatal depression, which was reduced to 21 (16.4%) following the intervention.

Conclusion:

CHARM intervention could promote quality sleep and reduce the risk of developing antenatal depression, thereby improving perinatal mental health.

Authors: Sharma Sanya , Sidana Ajeet , Mehta Shivangi , Bajaj Manoj Kumar
Published: October 2023

Background:

Schizophrenia causes significant neurocognitive impairment. Treatment with antipsychotics leads to improvement in psychopathology and neurocognitive functions.

Aim:

To see comparative effectiveness of aripiprazole and olanzapine on neurocognitive profile of patients with schizophrenia.

Materials and Methods:

This was a comparative, prospective, and interventional study. Patients with schizophrenia as per the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), were assessed on Brief Psychiatric Rating Scale (BPRS), Positive and Negative Syndrome Scale (PANSS), and neuropsychological tests at baseline. Patients were randomly assigned to aripiprazole (10–30 mg per day, orally) and olanzapine (5–20 mg per day, orally) groups on the basis of computer-generated random table number. Patients were reassessed at 10 weeks.

Results:

A total of 40 patients completed the study duration of 10 weeks. At baseline, the majority of patients showed significant impairment in one or more domains of neurocognition. Both aripiprazole and olanzapine led to improvement in psychiatric symptoms as well as neurocognitive profile. Aripiprazole treatment leads to significant improvement in mental speed as compared to olanzapine. A highly significant decrease in the value of the Stroop effect indicates improvement (P= 0.000**) with aripiprazole and visual–spatial constructive ability (P< 0.001). The olanzapine group showed highly significant improvement in performance of category fluency (P< 0.01) and verbal fluency (P< 0.01).

Conclusion:

The study concludes that aripiprazole and olanzapine have strong potential to improve specific domains of neurocognitive profile.
Engine Efficiency and Emissions Improvement in a Parallel-Series
PHEV
Authors: Jankord Gregory , Modak Aditya , Dalke Phillip , Midlam-Mohler Shawn
Published: October 2023

While there is a continued push toward mass adoption of electric vehicles
globally, internal combustion engines seem posed to continue to play a key role
in the mobility industry even as electrified powertrains continue to increase in
market share. For internal combustion engines to continue to propel people and
goods, engine technologies need to continuously improve in both efficiency and
emissions. This paper will explore six technologies to increase the efficiency
and reduce the emissions output of an engine in a plug-in hybrid-electric
vehicle (PHEV). The technologies employed on this prototype vehicle include
deceleration fuel cutoff, start–stop, increasing the mean engine operating
temperature, preheating the engine oil, implementing an electrically heated
catalyst, and air–fuel ratio control. Each of these technologies have been well
studied and have demonstrated robustness through decades of deployments on road.
However, pairing these technologies with a PHEV architecture will enable the
benefits of these technologies to be fully exploited. It will be demonstrated
that the combined application of these six technologies increased the
experimental vehicles miles per gallon gasoline equivalent by 22% and reduced
greenhouse gas emissions by 32% over a real-world driving emissions baseline.
This paper will explore the background and anticipated impacts that these
technologies should have, as well as demonstrate their implementation on the
experimental vehicle. Emphasis will be placed on the way each of these
technologies were tested and the environment that they were tested in. The
testing environments include an engine dynamometer, a chassis dynamometer, and
real-world driving emission tests. In all these settings, the efficiency and
emissions were measured. The final test involves a real-world driving emissions
test. The vehicle in question is an experimental PHEV developed by students at
The Ohio State University. Results and conclusions are drawn from the data
collected for how each of these technologies impacted engine operation in the
PHEV.
'We need to offer something better to the scholars of the future.' Which way forward for heterodox economics?
Authors: Heise Arne
Published: October 2023

After the global financial crisis, hopes were high that there would be a pluralisation of the economics discipline and a boost for heterodox economics that challenged dominant economic models. However, mainstream economics once again proved its enormous resilience and the future of alternatives to this mainstream is anything but certain. Geoffrey Hodgson's new book on this issue has sparked fresh discussions about the stunted development of heterodox economics and proposals for possible ways forward. This article will argue that the crucial factor for the future of heterodox economics is not converging on a single unified paradigm or raising the quality of research, but rather gaining access to different kinds of capital, first and foremost professorial positions at universities. Such access is severely restricted under present conditions as a result of epistemological and ontological discrimination. Heterodox economics can only flourish if the epistemic community of economists embraces paradigmatic pluralism as part of their academic culture, or if regulations are put in place to secure access to such capital and so to academic freedom.
A Plea for Pluralism
Authors: Marglin Stephen
Published: October 2023

Mainstream economics is one way of understanding how the economy works, but mainstream economists argue much more: that mainstream economics is the onlyway of understanding the economy. Mainstream economists should embrace pluralism for reasons suggested by John Stuart Mill: as a guard against the tyranny of the majority, a tyranny that fortifies itself against doubt not by reason but by power; even if the majority is right and the doubters wrong, engaging with doubt is a way to strengthen correct arguments; and, most likely, according to Mill, there is partial truth on the side of heterodoxy as well as on the orthodox side. The two elements of the power of mainstream economists are related: the police power over what is and what is not published in the major journals, and the role of publication in these journals in the tenure process. Pluralism is not an issue of concern to academics only. Economists of all stripes may try to construct the economy in the image of their theories, but for some time the mainstream has had the upper hand, just as it does in the academy. The push to deregulate the economy, which began in the United States during the Carter presidency, had its full flowering in the financial crisis of 2008.What will it take to allow heterodoxy into the academy? If history is any guide, innovations in economics take root when they are allied to successful political movements. One case in point is the symbiosis between Keynes’s General Theory and the New Deal and social democracy. Another is the resurgence of pre-Keynesian theory dressed up in the high-tech mathematics of New Classical theory and the coming to power of the apostles of neoliberalism in the 1980s. It’s a good bet that for a new economics to take hold in this century, it will do so in partnership, however tacit, with a new politics.
Mechanical Competencies and Fluid Absorption Profiles of Electrospun Polylactide Nanocomposite Fibres for Tissue Engineering and Regenerative Medicine Applications
Authors: V. Diwe Ihuoma , K. Aworinde Abraham , Ajewole Titus O. , Adeosun Samson O.
Published: October 2023

The mechanical, morphological and fluid permeability tendencies of agro-waste-reinforced Polylactic acid (PLA) composite fibres were explored. Treated and untreated rice husk fillers were composited with PLA pellets in dichloromethane and virgin and rice husk-reinforced composite fibres of PLA were produced through solution electrospinning. The samples were subjected to mechanical, morphological and fluid imbibition tests. The porous beads-in-string structures of reinforced PLA as seen from the morphological analyses were considered responsible for the greater fluid absorption capacity of the composites. The morphology was also found to dictate the mechanical properties of the samples with bead-free virgin PLA fibres showing stronger mechanical tendencies, but low fluid imbibition capacity. Two-way analysis of variance indicated that, unlike the effect of filler structural strength, due to alkali treatment, which statistically affected impact energy (p = 9×10-4) and ductility (p = 2.12×10-4), the effect of filler weight per cent showed no statical significance. Statistically, the fluid imbibition capacity was found to be significantly affected by both the filler structural strength and the filler weight per cent. The competencies displayed by the fibres show that they can find applications in wound dressing and tissue engineering purposes.
A forgotten Roman marble base in the National Museum of Archaeology
Authors: Wilson Roger  J. A.
Published: October 2023

A badly damaged Roman marble base now in Valletta, Malta, was first published in 1647 and then in 1787. It has been neglected since, mainly because there have been doubts about whether or not it is a genuine antiquity. This study argues for its authenticity, and contextualizes the relief sculpture that decorates three of its sides. The front carries a depiction of Sicilia, the personification of the Roman province of Sicily to which the Maltese Islands belonged. The image is set in context within the small group of known personifications of Sicilia elsewhere. Identical side panels each show a man with what is interpreted here as a turtle balanced on his knee, an apparently unique depiction of these creatures in Roman sculpture. It is suggested that turtles, now scarce in the Mediterranean, were once plentiful in the waters off both Malta and Sicily. In a secondary period, perhaps in the late eighteenth century, the base was badly mutilated during its conversion for use as a fountain. Whether it ever functioned as such is uncertain.
Análisis del Derecho a la intimidad personal y familiar en la difusión de videos e imágenes de ebrios consuetudinarios y toxicómanos en redes sociales
Authors: Villa Aucapiña Jonnathan Vinicio , Calle Masache Nube Catalina
Published: October 2023

El Derecho a la Intimidad Personal es reconocido constitucionalmente por la legislación ecuatoriana y los Tratados Internacionales sobre Derechos Humanos, el cual prohíbe la publicación sobre datos concernientes a la vida íntima de una persona. El objetivo del estudio es analizar el derecho a la intimidad en la publicación de videos e imágenes de toxicómanos y ebrios consuetudinarios en redes sociales tomando en consideración que en algunas ocasiones son utilizadas de manera inadecuada. El método investigativo utilizado es cualitativo mediante la revisión de doctrina y jurisprudencia sobre el tema en estudio, destacando la necesidad en el Ecuador de implementar una normativa clara y específica sobre el uso de internet y redes sociales, pues varios individuos como en el caso de toxicómanos y ebrios consuetudinarios ven expuesta su enfermedad a través de estos medios. Por tal razón, se concluye que, es necesario implementar programas de educación y concientización sobre los riesgos y consecuencias de compartir contenido sensible en las redes sociales.
A Literature Review of Pruritus in Elderly
Authors: Silvestri Silvestri , Noviandini Anggraeni
Published: October 2023

Pruritus is a relatively common symptom that anyone can experience at any point in their life and is more common in the elderly. Pruritus in elderly can be defined as chronic pruritus in a person over 65 years old. The pathophysiology of pruritus in elderly is still unclear, and the quality of life is reduced. Generally, itch can be clinically classified into six types: Itch caused by systemic diseases, itch caused by skin diseases, neuropathic pruritus, psychogenic pruritus, pruritus with multiple factors, and from unknown causes. Senile pruritus can be defined as a chronic pruritus of unknown origin in elderly people. Various neuronal mediators, signaling mechanisms at neuronal terminals, central and peripheral neurotransmission pathways, and neuronal sensitizations are included in the processes causing itch. A variety of therapies are used and several novel drugs are being developed to relieve itch, including systemic and topical treatments.

Published: October 2023

Aluminium alloys of the Al-Si and Al-Mg-Sc systems, which are promising for nuclear power generating facilities, were studied. The AK9 aluminium casting alloy and the 1545 wrought alloy were selected as the study materials. Modification of aluminium alloys with a multicomponent nanodispersed modifier based on Mg2Si and SiC was proposed. Grain grinding of modifying alloys by 1.5–2 times, strength properties increasing by 12…18%
and corrosion resistance improving were achieved. The mechanism of action of the multicomponent nanodispersed modifier in an aluminium melt was proposed. The use of such modifiers facilitates the technological process, is environmentally safe, and leads to a uniform distribution of the introduced nanocompositions, which increases the
strength and stability of alloys. The results achieved showed the effectiveness of modification aluminium alloys with nanodispersed compositions.

The effectiveness of the use of magnesium potassium phosphate cements (MKPC) as protective matrices for radioactive waste was investigated in this work from the point of view of the main elements leaching. Fly ash and blast-furnace slag were used as MKPC fillers. Leaching tests were performed on monolithic MKPC samples according to ANSI/ANS 16.1 test. Based on the obtained data, the cumulative leaching fractions, leaching
mechanisms, effective diffusion coefficients and leaching indices K, Mg, P, B, Si, Al, and Ca were determined. The values of the calculated leaching indices (>10) of the constituent elements indicate that the characteristics of the studied MKPC matrix are acceptable for radioactive waste immobilization.

This review presents an examination of various studies investigating the impact of deposition process conditions and structural characteristics of TiN-based vacuum-arc coatings on their ability to withstand cavitation erosion in water. The structural and phase composition of TiN coatings is influenced by two key technological parameters: the nitrogen pressure in the vacuum chamber and the substrate bias potential. However, it has been observed that vacuum-arc alloy coatings such as TiSiN and TiAlYN exhibit notably lower resistance to cavitation erosion. Additionally, research on multilayer Ti-TiN coatings with varying numbers and thickness ratios of layers has not shown an improvement in resistance to cavitation wear when compared to single-layer coatings deposited under optimal conditions. On the other hand, single-phase stoichiometric TiN coatings deposited at a higher nitrogen pressure of 2 Pa and a bias potential of up to -300 V have demonstrated remarkable resistance to cavitation wear. These coatings could be effectively utilized to protect the titanium alloy Ti-6Al-4V against cavitation damage.

Background: A new Ultra performance liquid chromatographic analytical method was developed and validated for estimation of Quercetin in bulk powder. The reverse phase chromatographic elution using UPLC was carried out in gradient mode on C-18 column (Phenomenex Luna 5 µm, 150 mm X 4.6 mm) as stationary phase utilizing a mobile phase composed of Acetonitrile: 0.1 % formic acid buffer (50:50 v/v) with a flow rate of 1 ml/min and injection volume of 10µl.  The analysis was performed at temperature of 400C and detection of eluent was carried out using photo diode array at 371 nm. The newly developed Ultra performance liquid chromatography method was validated in terms of linearity and range, system suitability, specificity, precision, sensitivity, robustness, ruggedness and accuracy as per ICH guidelines. Results: The retention time of quercetin was found to be at 3.9 min with total run time of analysis is 7 minutes. The linearity was observed between the concentration ranges from 0.5 to 16µg/ml with correlation coefficient 0.999. The precision assays values were found to be less than 2% for both the drugs. The Limit of Detection and Limit of Quantification were 0.47µg/ml and 1.44µg/ml for Quercetin. The mean percentage recovery values were found to be within the range of 90-110 %. Conclusion: The proposed method was found to be simple, specific, precise, sensitive, robust, rugged and accurate and can be used for routine quality control analysis of Quercetin.

Apabahuka (Frozen shoulder-FS) is a disease that affects the shoulder joint. Frozen shoulder is also known as adhesive capsulitis, it is characterized by pain and stiffness in the shoulder joint and upper arm muscles with restricted mobility. Apabahuka is a Vataj vyadhi associated with Kapha dosha. The prevalence of FS varies from 11.4% to 19% in India. FS is commonly found between 40 to 70 years and most common in females. Various modalities are available to treat FS such as nonsteroidal anti-inflammatory drugs, corticosteroids, physiotherapy, ultrasound therapy, arthroscopic surgery, or a combination of treatments done still no satisfactory results are found. In the present case report, a 50-year-old female patient consulted with the chief complaints of pain, stiffness, restricted mobility of shoulder joint and pain while lifting weight along with disturbed sleep. Patient was diagnosed as a Abhighatjanya Apabahuka (Traumatic FS). The patient was assessed on the basis of Visual Analogue Scale (VAS), Stiffness Gradation, Tenderness Gradation and range of movements using Goniometer. Patient was treated with Panchakarma therapies and internal medication. The outcome of Ayurvedic management of FS was encouraging to reduce subjective and objective parameters.

In production activities, the problem of inventory is one thing that must be considered in order to avoid waste in the production process. This study shows the control of raw material inventory in a production to get the optimal level of inventory. The just in time (JIT) method reduces the amount of inventory so that it can reduce costs as efficiently as possible. Inventory control with the just in time (JIT) method is the development of the economic order quantity (EOQ) method by reducing shipping lots. Based on this research, it is known that with the same data, using just in time (JIT) the costs incurred are smaller than the costs incurred previously. Costs previously incurred were Rp. 14,019,680.00 using economic order quantity (EOQ) the costs incurred were Rp. 8,497,593,00 while using just in time (JIT) the costs incurred were Rp. 3,800,239, 00 From these results it can be seen that with the just in time (JIT) method the production costs incurred are more efficient. The solution using the just in time (JIT) method is done with the help of MATLAB software.

A ideia de sistema se generalizou na sociologia, e foi a concepção de sistema social aberto de Parsons, que enfatiza a troca de elementos (energia, pessoas, informação) entre os sistemas, em Luhmann encontramos uma mudança radical de perspectiva que considera, a exemplo dos organismos vivos, que os “sistemas sociais operam fechados sobre sua própria base operativa, diferenciando-se de todo o resto e, portanto, criando seu próprio limite de operação. Luhmann, considera que o elemento básico de reprodução no sistema social é o processo de comunicação. Relativamente a cultura organizacional em um grupo corporativo ou estrutura de negócios de holding, o grupo inclui duas ou mais empresas diversificadas sob um único poder de controlo, governança e liderança.
