Community Local Wisdom and Efforts to Create Quality Marine Tourism
Authors: Arismayanti Ni Ketut
Published: December 2021

Marine tourism has the potential to develop various activities because it is supported by nature, culture and tourist activities. However, coastal and marine areas are vulnerable to damage and over exploitation. Various problems encountered in coastal and marine areas, such as garbage, damage to coral reefs, excessive fish management, social problems, conflicts of interest or limited governance. Local wisdom has a fundamental role as a way of life for people in preserving civilization. Likewise, the roles and efforts of stakeholders to participate in contributing to monitoring and providing protection for coastal and marine areas so that they can provide sustainable benefits. This research uses a mix of quantitative and qualitative methods, especially the explanatory sequential mixed method. Data were analyzed using descriptive qualitative, Importance Performance Analysis and Customer Satisfaction Index. Data were collected by observation, questionnaires, and interviews by raising several cases in Indonesian territory related to local wisdom from a cultural perspective, the role of NGOs from a nature conservation perspective, and tourism assessment from a tourist market perspective. Local wisdom from a cultural perspective, a community that has potential and a central role in conservation and preservation efforts, resource development and science and technology that can be passed on to the next generation based on knowledge, values, skills, resources, decision-making and local solidarity. Stakeholders in terms of nature protection have a major role and potential contribution by supporting, implementing, advocating, engaging and influencing, and having a high commitment to realizing responsible and sustainable tourism. From a tourism point of view, it has several weaknesses related to the quality of tourist attractions in indicators, management, amenities and value for money, so that efforts are needed to improve the quality and variety of products, professional management, and various tourism activity innovations that have the value of novelty and meaningfulness for tourists.

Authors: Wiązek Paweł
Published: December 2021

Artykuł poświęcony jest dziejom regulacji prawnych dotyczących stanów nadzwyczajnych w XVIII-wiecznej rewolucyjnej Francji. Od stuleci stanowią one specyficzne reżimy prawne stosowane w państwach w okresach poważnego zagrożenia powszechnego bezpieczeństwa. Wielu historyków uznaje, że genezy nowożytnych rozwiązań prawnych w tym zakresie upatrywać należy we francuskim prawie publicznym przełomu XVIII i XIX wieku. Tym właśnie tropem podążył autor, podejmując się analizy francuskich regulacji normatywnych czasów Wielkiej Rewolucji, poświęconych specyfice instytucji określanej jako l'état de siège. Eksplorując problem, korzystał z różnorodnych instrumentów metodologicznych, głównie egzegezy tekstu prawnego oraz komparatystyki prawniczej.
Olena Haleta, Joanna the Wife of Chuza by Lesya Ukrainka as a New Model of Communication in Modern Ukrainian Literature [Joanna, żona Chuzy Lesi Ukrainki jako nowy model komunikacji w modernistycznej literaturze ukraińskiej]re
Authors: Haleta Olena
Published: December 2021

This article examines the drama Joanna the Wife of Chuza (1909) by Lesya Ukrainka, who is one of the defining figures in the history of modern Ukrainian literature. This work is considered an example  of creating a new communicative model, introducing the poetics of an open work in the Ukrainian literature and establishing a new relationship between writer and audience. The incompleteness of the central image of this work, and therefore of the corresponding behavioral model and worldview, leads to the absence of a plot ending which would be the final solution to the conflict. In this way, Ukrainka establishes a new reading practice, not limited to experiencing the ‘life world’ of the author’s work. As reference to the history of thetext shows, it corresponds to the author’s conscious instruction, with which the composition of the work agrees: the events take place in a special period of time, when the previous story has already ended and the new one has not yet begun (after the crucifixion of Christ, but not after the resurrection). At the same time, the spatial organization of the work emphasizes the position of readers, turning them from interested witnesses to active searchers. The example of Joanna is all the more telling because it undermines the hegemony of the novel in twentieth-century literature and draws attention to literary forms that correspond to a particular literary situation, especially that of ‘submerged population groups’ (Frank O’Connor). The change introduced by Lesya Ukrainka at the level of a separate work is also a change within the genre as a way of communicating between an author and a reader; it is also a change in the very notion of literature as a certain type of aesthetic experience and as a culturally established way of cognitive and rhetorical response to a certain type of situation.
Dramatyczność kolorów historii
Authors: Kosicka-Pajewska Aleksandra
Published: December 2021

The drama of Katyń. The theory of colors, Julia Holewińska based on Józef Czapski’s Old Bielsko Memories, although largely processed. The protagonist of the play is Józef Czapski, a painter-capist, writer, intellectual, prisoner of Starobielsk, Pawliszczew Boru, Griazowiec, who builds his paintings in the performance with colors. The setting for these events is Kozielsk, where the artist was not held, which proves that this is not Czapski’s biography, nor is it a documentary account of camp life. The playwright, on the basis of a harsh and humiliating reality, showed human sensitivity. In Holewińska’s drama, Czapski acts as a guide through the camp experience through the eyes of a colorist. In each sequence, the artist expresses his view of color in art. There are two more allegorical characters in the drama: Our Lady of Kazan, who embodies three beings: Our Lady of Kazan (The Blessed Virgin of Kazan) – as the sacred, the real pilot Janina Lewandowska, and femininity in general. The second allegorical figure is the great Katyń liar, who personifies the whole apparatus of repression and oppression of the NKVD. The background for the conversations between these characters is a two-person choir – one out of a thousand and the Second of thousand. Art of Katyń. The theory of colors is devoted to painful historical events, despite the fact that it is subject to various playwriting procedures, it is moving in its meaning.

Published: December 2021

In an age when the global dissemination of digital information is transforming the way we read and write by foregrounding the interdependence of visual/verbal elements and languages, the reconstruction of identity and history in digital environments challenges binary translation processes. From this perspective, we interrogate the integration of visual and verbal elements in three Wikipedia articles, written in Polish, English, and Portuguese, about the topic “Polish death camp”. What is the role of translation in the semiotic construction of historical discourses in these articles? What are the conflicts generated by translated denominations? How do Wikipedia communities engage with the production of these cognitiverepresentations? This paper attempts to answer these questions.
Radioactive nuclei forβ+γPET and theranostics: selected candidates
Authors: Matulewicz Tomasz
Published: December 2021

Positron emission tomography (PET) is an established medical diagnostic imaging method. Continuous improvements are aimed at refining image reconstruction, reducing the amount of radioactive tracer and combining with targeted therapy. Time-of-flight (TOF)-PET provides the localization of the tracer through improved time resolution, nuclear physics may contribute to this goal via selection of radioactive nuclei emitting additional γ-rays. This additional radiation, when properly detected, localizes the decay of the tracer at the line of response (LoR) determined by two detected 511 keV quanta. Selected candidates are presented. Some are particularly interesting, as they are strong candidates for theranostic applications.
Updated picture of SARS-CoV-2 variants and mutations
Authors: Lippi Giuseppe , Mattiuzzi Camilla , Henry Brandon M.
Published: December 2021

The worldwide burden of coronavirus disease 2019 (COVID-19) is still unremittingly prosecuting, with nearly 300 million infections and over 5.3 million deaths recorded so far since the origin of the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) pandemic at the end of the year 2019. The fight against this new highly virulent beta coronavirus appears one of the most strenuous and long challenges that humanity has ever faced, since a definitive treatment has not been identified so far. The adoption of potentially useful physical preventive measures such as lockdowns, social distancing and face masking seems only partially effective for mitigating viral spread, though efficacy and continuation of such measures on the long term is questionable, due to many social and economic reasons. Many COVID-19 vaccines have been developed and are now widely used, though their effectiveness is challenged by several aspects such as low uptake and limited efficacy in some specific populations, as well as by continuous emergence of new mutations in the SARS-CoV-2 genome, accompanying the origin and spread of new variants, which in turn may contribute to further decrease the effectiveness of current vaccines and treatments. This article is hence aimed to provide an updated picture of SARS-CoV-2 variants and mutations that have emerged from November 2019 to present time (i.e., early December 2021).

Authors: Muleta Negasa , Badar Altaf Q H
Published: December 2021

Electricity is the most sought after resource in this world and is crucial for the development of any community. The power system structure has been changing according to the evolving scientific technologies. A novel concept in this direction is a Microgrid (MG) which is a small power system having generation and distribution with negligible presence of transmission. A MG can operate in off-grid (standalone) or grid-connected mode. The objective of this study is to perform techno-economic analysis and to design a MG model for the purpose of rural electrification. The region being considered has different resources which are capable of providing reliable supply to the load. The proposed model is compared economically with the option of grid extension. The study considers power system reliability and economic feasibility as the primary objectives for MG modelling. The village of Jarre which is located in the eastern part of Ethiopian, Somali region, is selected for this study. Particle Swarm Optimization is implemented for obtaining the most economic and reliable MG having Hybrid Renewable Energy Sources (HRES). The simulation is performed using MATLAB and Homer.
Geochemical characterization of the source rock intervals, Beni-Suef Basin, West Nile Valley, Egypt
Authors: Edress Nader A. A. , Darwish Saudy , Ismail Amir
Published: December 2021

Geochemical and lithological investigations in the WON C-3X well record five organic-matter-rich intervals (OMRIs) of effective source rocks. These OMRIs correspond to moderate and good potentials. Two of these intervals occurred within the L-Kharita member of the Albian age represent 60.97% of the entire Albian thickness. The rest of OMRIs belongs to the Abu-Roash G and F members of the Late Cenomanian–Santonian age comprising 17.52 and 78.66% of their total thickness, respectively. The calculated heat flow of the studied basin is high within the range of 90.1–95.55 mW/m2 from shallower Abu-Roash F to deeper L-Kharita members. This high-heat flow is efficient for shallowing in the maximum threshold expulsion depth in the studied well to 2,000 m and active source rock depth limit to 2,750 m. Thermal maturity and burial history show that the source rock of L-Kharita entered the oil generation from 97 Ma till the late oil stage of 7.5 Ma, whereas the younger Abu-Roash G and F members have entered oil generation since 56 Ma and not reached peak oil yet. Hence, the source rock intervals from Abu-Roash F and G are promising for adequate oil generation.

Published: December 2021

Backgrounds

Hepatocellular carcinoma (HCC) is a diversity of hepatocellular neoplasms and is more prevalence in people with chronic liver disease and cirrhosis. It has been revealed that modification in miRNA regulation possibly will be elaborated in HCC pathogenesis.

Materials and methods

In this research 40 samples of HCC subjects and 40 samples of healthy liver were considered. Total RNA was obtained from paraffin-embedded tissue blocks and miR-515, miR-623 and miR-1272 gene expression levels were quantified by Real-Time Quantitative Reverse Transcription PCR. Likewise, the Notch protein quantity was assayed in ffpe materials by immunohistochemistry.

Results

Our study disclosed that Notch protein deals was ominously elevated in cancer cells than healthy cells (p<0.05). Data analysis also displayed that miR-515, miR-623 and miR-1272 expression levels were 3.8, 4.7, and 2.9 fold in normal tissues, respectively (p<0.05). Furthermore, it was found that expression levels of these genes are not dependent by hepatitis B and hepatic cirrhosis and it could be used as a marker of high specificity and sensitivity for the diagnosis of HCC.

Discussions

Our study demonstrated main role of miR-515, miR-623 and miR-1272 in HCC pathogenesis and similarly disclosed that these genes expression could be utilized in HCC prognosis.

Authors: Aleksandraviciute Laima , Malinauskiene Laura , Cerniauskas Kestutis , Chomiciene Anzelika
Published: December 2021

Background

Chronic urticaria is a common disease. Plasmapheresis is an alternative treatment that can be appropriate for patients who are resistant to treatment with 2nd generation antihistamines or for whom treatment with omalizumab is unsuitable.

Objective

To investigate the effect of plasmapheresis treatment in chronic urticaria.

Methods

A retrospective analysis was performed based on the data of 98 patients suffering from refractory chronic urticaria who received plasmapheresis as an alternative treatment in Vilnius University’s Hospital Santaros Clinics from 2000 to 2020. The efficiency of the treatment was evaluated by clinical judgment.

Results

58.2% of the patients exhibited a complete or significant response; of these, 37.8% had temporary relief of symptoms and 20.4% achieved disease remission; 41.8% showed no response to the plasmapheresis. Men (34.8%) had a tendency to achieve disease remission more often than women (16%) (p < 0.05). One patient did not finish the plasmapheresis treatment due to the symptoms’ exacerbation and treatment with omalizumab was initiated.

Conclusion

Plasmapheresis is a safe and effective alternative treatment when traditional treatment is unavailable or does not relieve symptoms completely. Our data showed that plasmapheresis was effective in more than half of our patients.
Controlling asymmetric transmission phase in planar chiral metasurfaces

Published: December 2021

Metasurfaces with ultrathin artificial structures have attracted much attention because of their unprecedented capability in light manipulations. The recent development of metasurfaces with controllable responses opens up new opportunities in various applications. Moreover, metasurfaces composed of twisted chiral structures can generate asymmetric responses for opposite incidence, leading to more degrees of freedom in wave detections and controls. However, most past studies had focused on the amplitude responses, not to mention using bi-directional phase responses, in the characterization and light manipulation of chiral metasurfaces. Here, we report a birefringent interference approach to achieve a controllable asymmetric bi-directional transmission phase from planar chiral metasurface by tuning the orientation of the metasurface with respect to the optical axis of an add-on birefringent substrate. To demonstrate our approach, we fabricate planar Au sawtooth nanoarray metasurface and measure the asymmetric transmission phase of the metasurface placed on a birefringent sapphire crystal slab. The Au sawtooth metasurface-sapphire system exhibits large oscillatory behavior for the asymmetric transmission phase with the tuning parameter. We confirm our experimental results by Jones matrix calculations using data obtained from full-wave simulations for the metasurface. Our approach in the characterization and light manipulation of metasurfaces with controllable responses is simple and nondestructive, enabling new functionalities and potential applications in optical communication, imaging, and remote sensing.
Nanomechanical and dynamic mechanical properties of rubber–wood–plastic composites
Authors: Zhou Yonghui , Hui David , Wang Yuxuan , Fan Mizi
Published: December 2021

This article presents the assessment of bulk and in situ mechanical properties of rubber–wood–plastic composites (RubWPC) and their correlations, aiming to obtain a thorough understanding of mechanical behaviour of RubWPC, which is an essential prerequisite in realising their optimal design and applications. Dynamic mechanical analysis results showed that the composites treated with multiple coupling agents (combination of maleic anhydride polyethylene [MAPE] and bis(triethoxysilylpropyl)tetrasulfide and combination of MAPE and vinyltrimethoxysilane) exhibited greater storage modulus than both the untreated and single coupling agent treated composites owing to their superior interfacial bonding quality. The shift of relaxation peak and T
g towards higher temperatures observed in the treated composites confirmed the enhancement of interfacial interaction and adhesion. Nanoindentation analysis suggested that the composite with optimised interface (MAPE and Si69 treated) possessed better nanomechanical property (elastic modulus) due to the resin penetration into cell lumens and vessels and the reaction between cell walls and coupling agents.
Synthesis and encapsulation of iron oxide nanorods for application in magnetic hyperthermia and photothermal therapy
Authors: Mona Lijo P. , Songca Sandile P. , Ajibade Peter A.
Published: December 2021

The synthesis, characterization, and applications of iron oxide nanorods have received attention in recent years. Even though there are several studies on the biological applications of iron oxide nanoparticles, recent studies have shown that rod-shaped iron oxides are effective in magnetic hyperthermia (MHT) as therapeutic technique to treat cancer. This review focused on the synthesis and encapsulation of magnetic iron oxide nanorods (MIONRs) and their use in (MHT) and photothermal therapy (PTT) for cancer cells. Among the synthetic methods that have been used to prepare MIONRs, some could be used to precisely control the particle size of the as-prepared magnetic iron oxide nanoparticles (MIONs), while others could be used to prepare monodisperse particles with uniform size distributions. Some of the results presented in this review showed that magnetic oxide nanorods are more potent in MHT than polyhedral-shaped MIONs. The review shows that mixtures of polyhedral- and rod-shaped MIONs resulted in 59 and 77% cell death, while monodisperse MIONRs resulted in 95% cell death. It could thus be concluded that, for magnetic iron oxide to be effective in MHT and PTT, it is important to prepare monodisperse magnetic oxide nanorods.

Published: December 2021

This study investigated the effects of mixing Moringa oleifera seed oil with soybean (Glycine max) seed oil in enhancing the physical and chemical properties of soybean oil during repetitive frying. Different blends (100:0, 50:50, and 70:30) of soybean and M. oleifera seed oils were formulated, while soybean oil served as control. All these oil samples were used for frying potato (Ipomoea batatas) slices. The quality of the fried oil samples was evaluated by determining the smoke point, refractive index (RI), viscosity, colour, peroxide value, iodine value, and free fatty acid (FFA). The range of values obtained were smoke point (158.7–172.3°C), RI (1.46–1.49°C), colour (6.0–9.42), viscosity (0.41–2.13 mm2/s), peroxide value (0.93–5.16 meq/kg), iodine value (87.16–64.71 mg/100 g), and FFA (0.3–1.95%), for different blends of soybean and M. oleifera seed oils and control. In terms of changes in the chemical and physical properties, during frying, soybean/M. oleifera seed oil mix of 70:30 had the lowest reduction in iodine value (87.56–68.73 mg/100 g), lowest increase in peroxide value (0.93–1.86 meq/kg) and FFA value (0.3–0.65%), while no changes in RI (1.47°C) was observed. The study revealed that mixing of soybean seed oil with M. oleifera seed oil at a ratio of 70:30 enhanced the physical and chemical properties of the soybean oil after two repetitive frying.

Authors: Romano Alicia , Kaski Juan Pablo , Dahlgren Jovanna , Kelepouris Nicky , Pietropoli Alberto , Rohrer Tilman R , Polak Michel
Published: December 2021

Objective

The study aims to assess the cardiovascular safety of growth hormone (GH) treatment in patients with Noonan syndrome (NS) in clinical practice.

Design

The study design involves two observational, multicentre studies (NordiNet® IOS and the ANSWER Program) evaluating the long-term effectiveness and safety of GH in >38,000 paediatric patients, of which 421 had NS.

Methods

Serious adverse events, serious adverse reactions (SARs) and non-serious adverse reactions (NSARs) were reported by the treating physicians. Cardiovascular comorbidities at baseline and throughout the studies were also recorded.

Results

The safety analysis set comprised 412 children with NS (29.1% females), with a mean (s.d.) baseline age of 9.29 (3.88) years, treated with an average GH dose of 0.047 (0.014) mg/kg/day during childhood. Cardiovascular comorbidities at baseline were reported in 48 (11.7%), most commonly pulmonary valve stenosis (PVS) and atrial septal defects. Overall, 22 (5.3%) patients experienced 34 safety events. The most common were the NSARs: headache (eight events in seven patients) and arthralgia (five events in three patients). Two SARs occurred in one patient (brain neoplasm and metastases to spine). No cardiovascular safety events were recorded in patients with NS. Five cardiovascular comorbidities in five patients were reported after initiation of GH treatment: three cases of unspecified cardiovascular disease, one ruptured abdominal aortic aneurysm and one PVS.

Conclusions

GH treatment had a favourable safety profile in patients with NS, including those with cardiovascular comorbidities. Prospective studies are warranted to systematically assess the safety of GH treatment in patients with NS and cardiovascular disease.
DAR LA MANO: LA POLÍTICA COMO AMISTAD
Authors: Rivera Víctor Samuel
Published: December 2021

El presente texto intenta dar unos alcances iniciales para un enfoque constructivista de la filosofía política y la organización social basado en el hecho de la amistad; particularmente en el saludo tomado como un acontecimiento de amistad. El mero saludo, el acercamiento más básico de empatía, sería el acontecer de un mundo, de un mundo entero caracterizado por su exigencia de ser, de ser realizado y conservado. Esta exigencia procedería de un fondo arcaico insondable, que sería accesible en la idea del número de los amigos. Se trata de una aporía que muestra a la vez el carácter abierto, pero no infinito, de un grupo de referencia basado en la ternura de algo común.
DECISIÓN COMO CURSO, MITO COMO RECURSO. UNA CRÍTICA AL DECISIONISMO SCHMITTIANO
Authors: Morro Delgado Joan
Published: December 2021

El decisionismo schmittiano es uno de los tópicos principales de la filosofía política contemporánea. Es a menudo recurrido entre quienes critican el liberalismo político, sea en su forma parlamentaria o mecanicista. El objetivo de este artículo es explicitar los cimientos, las implicaciones y las tesis más problemáticas de este decisionismo desde un planteamiento alternativo al de la fe. Se intenta mostrar tanto la presencia de Kierkegaard como el rechazo de Hegel en el reto que Schmitt presenta a la filosofía política, así como reinterpretar sus concepciones del mito y la soberanía en un marco crítico con el pensamiento liberal. Concluyo sosteniendo que los sesgos conceptuales de Schmitt comportan un absolutismo político no menos criticable.
Folk Liturgies and Narratives of Holy Wells among the Yoruba of Southwest Nigeria
Authors: Raheem Oluwafunminiyi
Published: December 2021

Building on Celeste Ray’s extensive research on Ireland’s holy wells, I show how folk liturgies underlie meanings that are closely related to some of the practices that manifest around holy wells among the Yoruba in southwest Nigeria – meanings that are often neglected in the holy wells literature. I adapt some holy wells terms as they appear in existing studies for illustrative as well as for comparative purposes. Their interpretation and analysis will, however, focus on the liturgical narratives that best fit the article’s perception of what is local to holy wells among the Yoruba. With a focus on two holy wells, Olokun and Ori Aye, the article draws on the testimonies of local knowledge, close research encounters of ritual practices and performances and readings from extant literature to open the window through which holy wells and their various manifestations in the socio-cultural life among the Yoruba could be properly assessed and adequately understood.

Published: December 2021

OBJECTIVE

To describe challenges in inpatient pediatric quality and safety during the coronavirus disease 2019 (COVID-19) pandemic.

METHODS

In a previous qualitative study, our team sought to broadly describe changes in pediatric inpatient care during the pandemic. For both that study and this ancillary analysis, we purposefully sampled participants from community and children’s hospitals in the 6 US states with the highest COVID-19 hospitalization rates from March to May 2020. We recruited 2 to 3 participants from each hospital (administrators, front-line physicians, nurses, caregivers) for semistructured interviews. We used constant comparative methods to identify themes regarding quality and safety challenges during the pandemic.

RESULTS

We interviewed 30 participants from 12 hospitals. Participants described several impacts to clinical workflows, including decreased direct clinician-patient interactions and challenges to communication, partly addressed through innovative use of telehealth technology. Participants reported changes in the discharge and transfer process (eg, discharges, difficulties accessing specialized facilities). Participants also described impacts to hospital operations, including changes in quality monitoring and operations (eg, decreased staff, data collection), increased health risks for clinicians and staff (eg, COVID-19 exposure, testing delays), and staff and supply shortages. Participants voiced concerns that negative quality and safety impacts could include increased risk of preventable safety events and hospital readmissions, and decreased patient engagement, education, and satisfaction.

CONCLUSIONS

We identified several impacts to clinical workflows and hospital operations during the pandemic that may have affected inpatient pediatric care quality and safety. Our findings highlight potentially important areas of focus for planning pandemic recovery, preparing for future pandemics, and conducting future research on inpatient pediatric quality and safety.

Published: December 2021

The prevalence of dyslipidaemia has been increasing in the Asia-Pacific region and this is attributed to dietary changes and decreasing physical activity. While there has been substantial progress in dyslipidaemia therapy, its management in the region is hindered by limitations in awareness, adherence and healthcare costs. The Asian Pacific Society of Cardiology (APSC) developed these consensus recommendations to address the need for a unified approach to managing dyslipidaemia. These recommendations are intended to guide general cardiologists and internists in the assessment and treatment of dyslipidaemia and are hoped to pave the way for improving screening, early diagnosis and treatment. The APSC expert panel reviewed and appraised the evidence using the Grading of Recommendations Assessment, Development, and Evaluation system. Consensus recommendations were developed, which were then put to an online vote. The resulting consensus recommendations tackle contemporary issues in the management of dyslipidaemia, familial hypercholesterolaemia and lipoprotein(a) in the Asia-Pacific region.
Delito y prosperidad: una paradoja latinoamericana
Authors: Bergman Marcelo
Published: December 2021

En este trabajo se argumenta que la actual ola delictiva latinoamericana tiene características singulares vinculadas a procesos sociales, políticos y económicos que contribuyeron a la expansión del delito en la región. Se muestran aspectos poco estudiados y que han contribuido fuertemente a este crecimiento de la criminalidad. Se sostiene en primer lugar, que la criminalidad es un problema regional que afectó a todos los países. En segundo lugar, que el crimen se ha convertido en un “negocio rentable” asociado a la expansión de mercados ilícitos. En tercer lugar, que existen dos tipos de crecimiento delictivo (equi- librios) y que es necesario comprender sus dinámicas para distinguir entre delincuencia contenida y criminalidad fuera de control. Se avanza con hipótesis para describir por qué la capacidad disuasiva de los estados es moderada en los primeros y colapsa en los segundos.
Criminalidad homicida, capitalismo y democracia
Authors: Gómez Albarello Juan Gabriel , Corzo Salamanca Jimmy Antonio
Published: December 2021

En este artículo revisamos el debate acerca de un tipo particular de criminalidad, los homicidios, y me- diante un modelo estadístico de análisis de componentes principales y un agrupamiento de 44 países basado en esos componentes, proporcionamos evidencia acerca de su carácter multicausal. Las variables incluidas en el modelo son, además de la tasa de homicidios, los niveles de impunidad de cada país; los niveles de desigualdad, medidos por el Índice Palma; así como la confianza en la policía y en la justicia, y la percepción de que el gobierno atiende las demandas de sus ciudadanos, como proxies de la legitimidad de las autoridades. El modelo logra dar cuenta de aproximadamente el 80 % de la variación observada. Con base en la discusión acerca de los mecanismos causales que subyacen a esa variación, postulamos que los niveles de criminalidad son en gran parte una función del tipo de capitalismo y de democracia existente en cada sociedad. Este artículo también destaca el hecho de que la discusión acerca de las causas de la violencia se superpone con otras discusiones: una, teórica, acerca de los modelos de la acción social y otra, normativa, acerca de cuál podría ser la forma de organización social más justa.

Os resultados obtidos desvelam questões importantes sobre os objetivos do AEE a serem alcançados pelas crianças com autismo, bem como aos planos de intervenções desenvolvidos tomando como base suas necessidades. Além de descrever a organização dos atendimentos e as práticas pedagógicas desenvolvidas pela docente preconizadas pela metodologia TEACCH (Tratamento e Educação para Autistas e Crianças com Limitações), buscou-se compreender a adequação do comportamento e o processo de socialização para favorecer a construção da autonomia, de acordo com suas particularidades. Ademais, a presente investigação evidencia a relação entre professor do AEE, professor da rede regular de ensino e família da criança com TEA, e também os materiais pedagógicos e recursos multifuncionais utilizados nos atendimentos. Por fim, conclui-se que o trabalho pedagógico desenvolvido pela docente na sala do AEE está em consonância com os documentos nacionais que preconizam a inclusão, portanto decorrem da tentativa de romper as barreiras impeditivas à construção do conhecimento e à ocorrência de relações dialógicas e alteritárias entre os indivíduos.

In the present paper the change of measures technique for compound mixed renewal processes, developed in Tzaninis and Macheras [ArXiv:2007.05289 (2020) 1–25], is applied to the ruin problem in order to obtain an explicit formula for the probability of ruin in a mixed renewal risk model and to find upper and lower bounds for it.
Effect of pack carburizing with chicken egg shell powder agent and vibrator quenching on the mechanical properties of AISI 9310 steel
Authors: Sinarep Sinarep , Darmo Sujita
Published: December 2021

The effects of vibrator quenching (QV) on the carbon content, microstructure, and mechanical properties (surface hardness number, wear resistance) in the pack carburizing of AISI 9310 steel were studied. The aim of this research is to increase the surface hardness and improve the wear resistance of AISI 9310 steel. The problem that often occurs in the quenching treatment after pack carburizing is that the thick cooling medium does not evenly wet the surface of the specimen, so that the cooling rate is not uniform, the impact is the distribution of the specimen surface hardness is not the same. Therefore, it is necessary to research the implementation of the vibrator in the quenching treatment. 
The specimens were treated with pack carburizing at a temperature of 875 °C, soaking time for 3 hours. The carburizing agent consisted of chicken egg shell powder (CESP) and rice husk charcoal (RHC) with various weight ratios of 5 %:95 %, 15 %:85 %, and 30 %:70 %. Followed by quenching treatment using a 10 % cane molasses cooling medium and vibrator. Hardness testing was carried out using a Vickers microhardness tester, wear resistance test using the pin-on-disc method, and a scanning electron microscope (SEM-EDX) was used to observe changes in the microstructure and carbon elemental content on the specimen surface.
The results showed that the application of VQ caused the formation of a small martensite microstructure while without VQ it was large martensite and a few of residual ferrite. The highest surface hardness number is 685 kg/mm2, the wear resistance is 0.32 cm/mg for pack carburizing, using carburizing agent 70 % RHC, 30 % CESP and VQ. VQ causes a more even distribution of the thick cane molasses cooling medium so that the cooling rate of the specimens is uniform.

This paper reports a series of experimental studies to establish regularities of the integrated effect exerted on the specific heat capacity of polymer nanocomposites by such factors as the temperature regime of their production, the value of the mass fraction of the filler, and the temperature of the composite material. The studies were conducted for nanocomposites based on polypropylene filled with carbon nanotubes. When obtaining composites, the method of mixing the components in the melt of the polymer was used. During the studies, the temperature of nanocomposites varied from 295 to 455 K, the mass fraction of the filler ‒ from 0.3 to 10 %. The basic parameter of the technological mode for obtaining composite materials, the value of overheating the polymer melt relative to its melting point, varied in the range of 10...75 K.
It is shown that the temperature dependence of the specific heat capacity of the considered composites is sensitive to changes in the overheating of the polymer melt only in the region maximum values of the specific heat capacity. Concentration dependences of the specific heat capacity of the considered nanocomposites at different values of their temperature and the level of overheating of the polymer melt have been built.
The studies have been carried out to identify the effects of the influence of the above parameters on the coefficient of thermal diffusivity of nanocomposites. It has been established, in particular, that an increase in the level of overheating the polymer could lead to a very significant increase in the coefficient of thermal diffusivity, which is all the more significant the higher the proportion of filler and the lower the temperature of the composite material. It is shown that the level of overheating the polymer melt relative to its melting point is a parameter that can be used as the basis for the creation of polymer composite materials with specified thermophysical properties.

This paper considers features related to manufacturing the chromium oxide-based tool material. The process involved ultra-dispersed powders made of aluminum nitride. It has been established that the destruction of chromium oxide at high sintering temperatures is prevented through the reaction sintering of chromium oxide (Cr2O3) and aluminum nitride (AlN).
It was established that the structure of the composite depends both on the temperature and the duration of hot pressing. Thermodynamic calculations of the interaction between Cr2O3 and AlN showed that this interaction begins at a temperature of 1,300 °C. In contrast to hot pressing in the air, no СrN and Сr2N compounds were formed in a vacuum. With increasing temperature, the content of Al2O3 in solid solution becomes maximum at a temperature of 1,700 °C in the case of hot pressing in the air while in vacuum the content of Al2O3 remains unchanged within the entire temperature range of 1,300–1,700 °C. When increasing the time of hot pressing to 30 minutes, the size of individual grains reaches 10 μm. It has been shown that in the sintering process involving Cr2O3 and AlN, the plasma-chemical synthesis produces the solid solution (Cr, Al)2O3 at the interphase boundary, which improves the mechanical properties of the material.
The influence exerted on the quality of the machined surface of tempered hard steel when machining by the devised tool material based on chromium oxide with an optimal admixture of 15 wt % of ultra-dispersed aluminum nitride powder was investigated. It was determined that the quality of the machined hard steel surface improved compared to standard imported tool plates.
It was established that the resulting tool material, in addition to relatively high strength and crack resistance, also demonstrates high thermal conductivity, which favorably affects the quality of the machined steel surface, given that lubricants and coolants are not used during the cutting process.
