Kapraunia silviae (Rhodomelaceae, Rhodophyta), a new species from the South Atlantic Ocean
Authors: Brito Jhullyrson O.F. de , Cassano Valéria
Published: July 2024

Kapraunia is a genus recently segregated from Polysiphonia sensu lato, with only four species so far known. However, no species have been found on the South Atlantic coast. Recent collections in southwestern Brazil revealed specimens morphologically similar to Kapraunia spp. To investigate the identity of these specimens, we carried out a morphological and molecular study based on COI-5P and rbcL sequences. Phylogenetic analysis placed our samples within the genus Kapraunia as a new species with full support, described here as Kapraunia silviae sp. nov. K. silviae is recognizable by a combination of characters such as attachment by a basal disc and a prostrate system, branches developing laterally to the trichoblasts, 5–6 pericentral cells, rarely 4. The species differs from K. pentamera by the attachment form, segment proportions and tetrasporangial dimensions, and from K. schneideri by the number of pericentral cells, branch development and tetrasporangial arrangement. Re-examination of herbarium samples from Brazil in older collections also revealed misidentifications of K. silviae as “Carradoriella denudata”. This new species seems to be restricted to the Brazilian coast, being found only on the northern coast of São Paulo state. Our results reinforce the need for revision of Polysiphonia s.l. species on the Brazilian coast.

Objectives

GH-releasing peptide-2 (GHRP2) can be used for provocative growth hormone testing (GHT). Since it acts as a powerful stimulus for GH secretion, cut-off peak GH level in GHRP2 loading test (GHRP2T) is higher than in other GHT. Nevertheless, data on response at adolescents are limited. This report aimed to investigate peak GH levels in GHRP2T in adolescents.

Methods

Clinical data of adolescents after onset of puberty who underwent GHRP2T at our institution from May 2010 to March 2023 were collected retrospectively. Subjects were classified into three groups according to underlying diseases.

Results

A total of 23 patients were included: 12 in organic or genetic GHD (o/gGHD) group, three in idiopathic GHD (iGHD) group, and eight in short stature (SS) group. The median GH peak levels were 3.4 ng/mL in o/gGHD group, 88.9 ng/mL in iGHD group, and 90.1 ng/mL in SS group, indicating a robust response of GH peak levels in iGHD and SS groups. Two patients exceeded the cut-off for GHRP2T but below for other GHT, indicating the current cut-off for GHRP2T may miss some GHD patients.

Conclusions

The GH response to GHRP2T in adolescents except the o/gGHD group may be robustly responsive. For the correct diagnosis of GHD, the cut-off peak GH levels in GHRP2T in adolescents may require revisiting.
The most common graphicons in Mexican Spanish speaking WhatsApp communities composed of school parents
Authors: Flores-Salgado Elizabeth
Published: July 2024

The present study examined the pragmatic functions of graphicons used in six different WhatsApp communities created by and for school parents, written in Mexican Spanish, which had the purpose of sharing information relating to daily classroom concerns. A total of 4,824 WhatsApp messages written by these 143 school parents were analyzed using the taxonomy proposed by Herring and Dainas (2017, Nice picture comment! Graphicons in Facebook comment threads. In: Proceedings of the Fifthieth Hawaii International Conference on System Sciences. IEEE Press, pp. 2185–2194. http://hdl.handle.net/10125/41419). The findings revealed that emoji were the most common graphical device used and they were always visually connected to the verbal content of the speech acts they accompanied. Another result showed that photos were the second most preferred multimodal. These photos were impersonal and as well as emoji, they fulfilled requested tasks as this was a task-oriented group. The findings further suggested that the low frequency of the occurrence of stickers, videos, and GIFS was probably due to the particularities of this community of practice. Thus, the use of emoji and graphicons were constrained by the requested tasks of these communities.
Gaze and Arrows: Does the Gaze-Following Patch in the Posterior Temporal Cortex Differentiate Social and Symbolic Spatial Cues?
Authors: Görner Marius , Ramezanpour Hamidreza , Dicke Peter , Thier Peter
Published: July 2024

The gaze-following patch (GFP) is located in the posterior temporal cortex and has been described as a cortical module dedicated to processing other people's gaze-direction in a domain-specific manner. Thus, it appears to be the neural correlate of Baron-Cohen's eye direction detector (EDD) which is one of the core modules in his mindreading system—a neurocognitive model for the theory of mind concept. Inspired by Jerry Fodor's ideas on the modularity of the mind, Baron-Cohen proposed that, among other things, the individual modules are domain specific. In the case of the EDD, this means that it exclusively processes eye-like stimuli to extract gaze-direction and that other stimuli, which may carry directional information as well, are processed elsewhere. If the GFP is indeed EDD's neural correlate, it must meet this expectation. To test this, we compared the GFP's BOLD activity during gaze-direction following with the activity during arrow-direction following in the present human fMRI study. Contrary to the expectation based on the assumption of domain specificity, we did not find a differentiation between gaze- and arrow-direction following. In fact, we were not able to reproduce the GFP as presented in the previous studies. A possible explanation is that in the present study—unlike the previous work—the gaze stimuli did not contain an obvious change of direction that represented a visual motion. Hence, the critical stimulus component responsible for the identification of the GFP in the previous experiments might have been visual motion.
Who Needs Privacy? Exploring the Relations Between Need for Privacy and Personality
Authors: Dienlin Tobias , Metzger Miriam
Published: July 2024

Privacy is defined as a voluntary withdrawal from society. While everyone needs some degree of privacy, we currently know little about who needs how much. In this study, we explored the relations between the need for privacy and personality. Personality was operationalized using the HEXACO personality inventory. Need for privacy was measured in relation to social, psychological, and physical privacy from other individuals (horizontal privacy); need for privacy from government agencies and companies (vertical privacy); as well as need for informational privacy, anonymity, and general privacy (both horizontal and vertical privacy). A sample of 1,550 respondents representative of the U.S. in terms of age, gender, and ethnicity was collected. The results showed several substantial relationships: More extraverted and more agreeable people needed substantially less privacy. People less fair and less altruistic needed more psychological privacy, social privacy, and anonymity, lending some support to the ‘nothing to hide-argument’. Emotionality and conscientiousness showed varied relations with need for privacy. More conservative respondents needed more privacy from the government.
How property relations shape experiences and transformative potential of urban growing spaces: Connecting land, food, and Earth justice perspectives
Authors: Holligan Bonnie , Howe Helena
Published: July 2024

This study uses both socio-legal and theoretical methods to examine the ambivalent role of property regimes in food system transformation. Combining an Earth justice perspective with a small-scale empirical study of how property and land-use laws affected experiences of growing spaces in an English city that included some element of collective ownership or management, we argue for greater diversity in formal legal structures (e.g., tenancy models), but also in concepts of land relationships. Our discussion diverts attention from individual entitlements to allocation of responsibilities and opportunities for human and interspecies collaboration. Growers’ experiences were shaped by productivist property narratives but provide a material basis to think beyond individual entitlement, reframing issues of security of tenure and public access in terms of responsibility and connection.

Kompleksinės kliūtys vyresnio amžiaus asmenų užimtumui: įveikimo priemonės ir jų tobulinimo galimybės
Authors: Moskvina Julija
Published: July 2024

In the context of the rapidly ageing Lithuanian society, it is important to create the conditions for the effective use of the potential of older people, including the sphere of employment. Although the employment rate of older Lithuanians is higher than the EU average, older people remain a vulnerable group of workers, especially in the face of labour market crises. The withdrawal from the labor market is attributable to inadequacies in qualifications or education that fail to align with the exigencies of the labor market, compromised health, adverse working conditions, and assorted factors concomitantly diminishing employment prospects. Reintegration into the labor market poses a formidable challenge for older individuals who have previously disengaged from it. The complex causes of older people’s exit from the labour market imply a comprehensive solution, but so far the country’s policies for older people have not sufficiently developed an integrated approach to enhancing employability, and the application of pesonalised measures is the responsibility of particular institutions.
The aim of the article is to assess the capacities of the current institutional infrastructure of public employment policies to respond to complex obstacles to the employment of elderly individuals and to identify relevant directions for the development of institutional collaboration in this sphere. Based on the latest statistical and analytical information, the paper identifies the current trends in employment and unemployment of the country’s elderly population and identifies the main factors determining their vulnerability in the labour market. It analyses the employment measures implemented by the Public Employment Service for currently unemployed older people. Based on the analysis, proposals are presented for the improvement of the measures in place, with particular emphasis on the development of institutional cooperation in the provision of comprehensive integration services.

На основі чисельно-аналітичної методики з використанням апроксимації функцій дискретними рядами Фур’є, в просторовій постановці, проведено чисельний аналіз напруженого стану нетонких еліптичних циліндричних оболонок, виготовлених з неперервно-неоднорідного матеріалу, який має квадратичний закон зміни модуля пружності по товщині та тришарових оболонок з ізотропними шарами за умови контакту шарів без проковзування та відриву. При цьому зовнішній та внутрішній шари мають модуль пружності, який за величиною дорівнює значенню для неперервно-неоднорідного матеріалу на зовнішній, внутрішній та серединній поверхнях оболонки відповідно. Оболонки знаходяться під дією нормального внутрішнього тиску і мають певні граничні умови на торцях. Досліджено вплив степеня еліптичності, закону зміни модуля пружності та наявність шаруватої структури на напружений стан розглядуваних оболонок. Результати проведеного чисельного модулювання показують, що використання неперервно-неоднорідних матеріалів істотно впливає на розподіл полів нормальних переміщень та напружень по товщині.

The article presents the results of the study of the effect of hot deformation on the structure and phase composition of the synthesized aluminum matrix composite of the Al-TiC system. The nature of the distribution of deformations and relative density over the volume of the porous workpiece during its hot deformation in a semi-closed die was established based on the results of computer simulation. Based on the obtained data, the impact of the stamping scheme on the phase and structure formation during the production of axisymmetric forgings from the dispersion-strengthened alumino-matrix composite was established. Modeling of the hot stamping process was carried out using the finite element method using the DEFORM 2D/3D software complex. The analysis of the obtained modeling results showed that at the final stage of the process, the intensity of deformations is almost uniform throughout the volume of the forging, while characteristic zones of difficult deformations are formed in the upper and lower parts of the section. A detailed analysis of the component deformations showed that the formation of stagnant zones is directly influenced by the radial component of the deformations. In turn, the analysis of the results of experimental studies showed that, despite the presence of stagnant zones, the given hot deformation scheme provides a uniform structure and phase composition of alumino-matric composites of the Al–TiC system, and the in-situ process of titanium carbide formation allows it to be evenly distributed throughout the volume of the composite . The uniformity of the structure and phase composition ensures low anisotropy of properties over the stamping volume, and therefore the proposed stamping scheme can be used to obtain semi-finished products with specified physical and mechanical properties. Keywords: hot forging, deformation, modeling, alumomatrix composites.

The use of powerful industrial heat pumps (HP) is a fairly effective means of rational and environmentally friendly use of energy resources both in individual households and in district heating (DH), as well as in production processes in various industries. Powerful HPs are used in Ukraine much less than in developed European countries. In fact, these are isolated cases. The post-war reconstruction of destroyed cities with their district heating systems gives Ukraine a unique chance to use modern energy-efficient technologies, including HP. As a result, efficiency will improve and DH competitiveness will increase due to the low cost of thermal energy for consumers. Almost all developed countries of the world have government financial support for the HP implementation. The purpose of this study is to determine the level and form of government financial support for projects to implement HP in DHs of Ukraine. Financial modeling of the implementation of heat pump plants shown that they are more expediently to be used in the mode of generating thermal energy than in the mode of regulating the electric load of power systems. It is shown that the projects of heat pump plants, which use the heat of flue gases as a source of low-potential heat (LPH), are the most economically attractive and practically do not require government financial support. Projects of heat pump plants, which use air, ventilation emissions, waste water, soil and groundwater, sea, rivers, and waste heat of technological processes as LPH, are not financially attractive without government financial support, and some of them are even unprofitable. The most appropriate comprehensive financial support is tax incentives and interest compensation on the loan. Sensitivity analysis showed that projects for the implementation of heat pump plants may be the most sensitive to the amount of generated thermal energy, the price of natural gas and electricity. Keywords: heat pumps, low-potential heat sources, district heating, financial obstacles, tax incentives, grants.

The purpose of this study is to develop methods and tools for long-term forecasting of electricity consumption based on an improved integrated method for predicting electricity demand, taking into account the peculiarities of electric use of the Kyiv Metro and its impact on the city's electricity consumption. The scientific novelty of the results obtained is the consideration of technological potential with measures for electric saving, pouring into Level II and Level III in the energy consumption model, which takes into account both the overall potential of electric saving (from structural and technological shifts) in the country as a whole, and the features at the regional level (the city of Kyiv) in the types of economic activity in the provision of transport services (Metro). During the work, material was collected on measures for electricity saving in the metro and forecasts for the development of this type of service provision (passenger transportation). To achieve sufficient energy consumption, it is important to introduce energy-efficient technologies that will reduce electricity costs without losing productivity and passenger service quality. Bimetallic contact rails are more efficient in terms of transmitting electric current and reducing energy losses. This innovation opens up new opportunities for the sustainable development of urban transport and contributes to the creation of more efficient and convenient conditions for city residents. Measures are provided to protect the structures and equipment of the section that is being designed and built, the metro line from electric corrosion. Calculation of electricity saving potentials at the regional level (Kyiv) made it possible to more accurately take into account the volume of implementation of energy saving measures, since such programs are developed at the regional level. These estimates are used to determine the technological potential of energy saving. The technological potential of electricity saving will reach the level of 600 million kWh by 2040, while maintaining the pace of economic development in Kyiv. Keywords: Metro, electric saving, electric saving potential, forecasting, energy efficiency, electricity.

The work presents the calculations of the control characteristics of the full-bridge resonant converter with a series resonant LLC circuit and frequency control by two methods - the first harmonic method and the superposition method. The theoretical results were verified by the analytical-structural modeling method. The power circuit of the resonant converter for the analysis of electromagnetic processes is replaced by a linear T-shaped circuit with two series resonant RLC-circuits and equivalent generators of rectangular voltages, which simulate a transistor inverter and a diode rectifier in the quasi-continuous current mode. Analytical-structural modeling method consists in partly analytical and partly structural ways of building a numerical model of the resonant converter in the form of the simulation model in the MATLAB-Simulink environment. Linear structural links of the model are created on the basis of integral equations of circles. Non-linear links are created based on the non-linear functions and causal relationships. The structural model based on these links takes into account the nonlinearity of the elements of the power circuit of the resonant converter and is based on simpler mathematical expressions compared to the equivalent mathematical model of the resonant converter. The structural model corresponds to the idea of the resonant converter in the form of the resonant circuit with independent equivalent voltage generators and allows to adjust the magnetic coupling coefficient between the transformer windings and simulate processes with arbitrary control functions of equivalent generators. The peculiarity of the use of the superposition method for calculating the static characteristics of the resonant converter is the need to match the voltage phases of the equivalent generators of the equivalent circuit during the changes of the operating frequency or relative load voltage. The dependence of the input voltage of the rectifier, which is simulated by the second equivalent generator, on the processes of the power circuit of the real resonant converter, determines the conditions for matching (adjusting) the phases of the equivalent generators.

The torque of a magnetoelectric torque motor with surface-mounted permanent magnets on the rotor was studied. The sinusoidal current supply mode is considered. The torque was calculated according to the static model of the magnetic field. It was determined that the sixth harmonic makes a significant contribution to the torque ripple. To reduce the sixth harmonic it is proposed to use a winding with a shortened pitch, for which it is necessary to make this winding in two layers. The optimal values of the number of pole pairs, the angular width of the magnets of the magnetic field exci-tation system, and the shortening of the winding pitch were determined. It was found that shortening of the winding pitch decreases the torque ripple by 2 ... 2.5 times. References 7, figures 6, tables 3.

Published: July 2024

Abstract. The phenomenon of violence in democratic countries such as Indonesia introduced a new angle in contextualizing modern Islamic political thought. The argument of mainstreaming fasad (violence or conflict) and islah (reconciliation) embedded in Islamic political thought preached by Azyumardi Azra as a part of the moderate Islam project (Islam wasathiyah) is considered a democratization process. This article seeks to examine Azyumardi Azra's thoughts in interpreting the concept of moderate Islam in the context of Indonesia's democratization, particularly regarding non-violence and social harmony. This article uses an interdisciplinary approach combining the interpretation of Islamic political thought, Middle-path political theory, and democratization analysis. It examines the Islamic revitalization formulating an anti-violence stance mainstreamed by Azyumardi that mediates the absolutist dogmatic beliefs and extremist political streams inciting violence. Finally, this article demonstrates how political thought embedded in Islam mainstreamed by Azyumardi benefits to strengthening democratization in Indonesia, moving away from violence.Keywords: Democratization, Middle-path Politics, Anti-violence, Revitalization of Islam, Wasatiyyah Islam.Abstrak. Kajian ini berfokus pada diskusi tentang pemikiran Azyumardi Azra dalam memaknai politik Islam jalan tengah (Islam wasathiyah) dalam upaya demokratisasi Indonesia, khususnya mengenai antikekerasan dan harmonisasi sosial. Dengan pendekatan Islam jalan tengah, ia berupaya mencari cara efektif mengatasi praksis kekerasan di Indonesia. Kajian ini menggunakan metode penelitian kualitatif dengan merujuk pada data-data primer melalui esai-esai dan buku-buku Azyumardi. Penelitian ini berhasil menganalisis pemikiran Azyumardi dalam merumuskan sikap antikekerasan sebagai gagasan revitalisasi Islam dengan menengahi keyakinan dogmatis absolut dan praksis politik ekstrem yang mendelegitimasi kekuasaan. Penelitian ini menyimpulkan, revitalisasi Islam yang dikemukakan Azyumardi merupakan cara efektif untuk mengatasi terjadinya kekerasan sebagai problematika demokrasi di Indonesia, kini dan di masa-masa mendatang. Kajian ini diharapkan dapat berkonstribusi bagi penguatan demokratisasi di Indonesia, yang jauh dari kekerasan.Kata Kunci: Politik jalan tengah, Islam wasathiyah, demokratisasi, revitalisasi Islam, antikekerasan.

During the baby’s well exam, he acutely decompensated and required resuscitation and transfer to the emergency department, where he was intubated for frequent apneic events. He was admitted to the NICU for management and further workup. Physical examination and initial laboratory tests were unremarkable. An EEG demonstrated electrographic and clinical seizures. His initial MRI was unremarkable, and infection studies revealed the diagnosis. We review the patient’s initial presentation, evaluation, hospital course, and the long-term implications of his diagnosis.
Los múltiples rostros de la democracia viajera. De Tracy y Tocqueville en Venezuela y Latinoamérica, 1824-1840
Authors: Perrone Galicia Luis Daniel
Published: July 2024

Objetivo: analizar las recepciones e interpretaciones que se hicieron en Venezuela, entre 1824 y 1840, de las nociones de democracia planteadas por Destutt de Tracy en su Comentario sobre el Espíritu de las Leyes y por Alexis de Tocqueville en La democracia en América, en comparación con las lecturas efectuadas en otros países latinoamericanos como Chile y México. Metodología: para ello se han tenido en cuenta los preceptos metodológicos de la historia intelectual y del pensamiento político de carácter contextualista, específicamente en lo atinente al estudio de las recepciones y traducciones internacionales de conceptos y argumentos. Originalidad: con este estudio procuramos cubrir parcialmente un vacío en la historiografía política venezolana, ya que no se ha prestado suficiente atención a las fuentes intelectuales de los conceptos de democracia empleados por los actores y pensadores políticos durante el siglo XIX y mucho menos a las semejanzas y diferencias en relación con el discurso político presente en otros países por la misma época. Conclusiones: sobre este aspecto en particular, nuestro trabajo no solamente demuestra la presencia de los conceptos formulados por De Tracy y Tocqueville en el pensamiento político venezolano, sino que además resalta la singularidad de las lecturas que se realizaron de esos autores en Venezuela, condicionadas por el predominio de sentimientos favorables a los gobiernos populares.

Published: July 2024

The teaching practice of noticing students’ thinking includes both attention to students’ mathematical strategies and interpretation of their mathematical understanding. This practice is further complicated when students are engaged with mathematical action technologies
while learning mathematics content because, in these contexts, teachers must also notice how the students’ engaged with the technology to develop their mathematical understanding. For this cross-institutional study, we focus on how preservice secondary mathematics teachers (PSMTs) coordinated
their noticing of students’ mathematical thinking and engagement in a technology-mediated environment. The PSMTs viewed artefacts of high school students working with a Desmos task focused on rational functions, specifically locating vertical asymptotes, and noticed the students’
mathematical thinking. Results showed it was easier for PSMTs to attend to and interpret the students’ spoken and written responses than for them to attend to and interpret the students’ engagement with the technology. Further, it was even more difficult for the PSMTs to coordinate
the students’ spoken and written responses with their technology engagement.
Russian Banks Financial Stability Loss Diagnostic: Multidimensional Logit-Model Approach
Authors: Shershneva Elena G. ,   Ural Federal University named after the First President of Russia B.N. Yeltsin, Hao Min Zhou ,   Qingdao University
Published: July 2024

The financial stability of the banking sector characterizes the "economic health" at the national and global levels and its deterioration is a cause of financial crises. Improving the toolkit for early diagnosis of financial problems is a key element of monitoring and forecasting banking risks. The purpose of the study is to examine the specific features of intrabank factors influencing the risk of financial stability loss in Russian banks. The research hypotheses are as follows: 1) the highly significant predictors of bank's financial instability risk are return on assets and overdue loans; 2) the impact degree of financial stability factors differs for medium- and long-term horizons of risk forecasting. The authors present multidimensional logit models for estimating the probability of the loss of financial stability by banks for 6 and 12 months based on four variables: capital adequacy ratio, overdue loans fraction over 90 days, return on assets, current liquidity ratio. It was revealed that a growth of return on assets has a positive significant effect on financial stability, and an increase in overdue loans has a negative significant effect on a bank's "financial immunity". It is shown the impact degree of financial stability factors is varied for different forecast horizons: the return on assets is a more relevant factor for 6 months, and the overdue loans fraction is more important for a 12 month period. The theoretical significance consists in better scientific understanding of factors impacting on a bank's financial stability. The practical significance lies in the possibility for commercial banks to use econometric models and conclusions in analytical and risk-predictive algorithms.

Published: July 2024

Technology is meant to give people a platform to express themselves. Therefore, network neutrality is a creation for platform where contents, applications, services are to move on the internet without any form of restrictions. It is worrisome to some that internet providers are beginning to give unfair advantage to some data streams thereby making it almost difficult for smaller content creators and to grow. Network neutrality is the principle that internet provider and the Government should treat internet traffic the same. It connotes putting policy and regulatory measures in place to ensure open access and fair treatment of all internet users. This paper discusses the concept of network neutrality according to Tim Wu. It also considers the advantages and disadvantages of network neutrality. It discusses network neutrality in the United States and also the provisions of the Draft code released by the Nigerian Communication Commission in 2017. Hence, a doctrinal methodology was adopted using primary and secondary sources
DOMESTIC VIOLENCE: CRIMINOLOGICAL PROFILES, PREVENTION AND VICTIM PROTECTION
Authors: Peluso Pasquale
Published: July 2024

One of the reasons for the high dark number that characterizes domestic violence is that women often fail to recognize violence especially in the forms of psychological or economic violence, which, however, through the humiliations, denigrations with which it is substantiated annihilates women's personalities. Often women decide to turn to an anti-violence center only after they have suffered physical violence, and there they discover, then, that they have also been victims of other forms of violence that had not, however, been experienced as such, despite the outcry raised by the media.

HISTORICAL ASPECTS OF THE EVOLUTION OF NATIONAL SECURITY IN THE REPUBLIC OF MOLDOVA
Authors: Gordilă Dianu
Published: July 2024

National security represents a fundamental pillar of the rule of law, which has gone through a long path throughout history and has undergone a series of geopolitical and economic changes. After gaining independence in 1991, the Republic of Moldova gradually developed its institutions in the field of national security to ensure the protection of its interests and state sovereignty. Following the dissolution of the Soviet Union, during the post-independence transition period, the Republic of Moldova faced significant challenges related to its national security system, including political instability, external pressures, ethnic and territorial conflicts. In this context, the creation and consolidation of institutions in the field of security has been and continues to be an important step for the Republic of Moldova in maintaining state sovereignty and democracy. Throughout its history, the Republic of Moldova has joined international organizations, which is an integral part of efforts to strengthen national security and promote the democratic values of the rule of law.
رِوايةُ نُقّادِ المُحدِّثِينَ الحَدِيثَ أَو بَعضَهُ بالمَعنى شعبة بن الحَجّاج في قوله: «كأنه كَرِه ذلك» نَمُوذجًا
Authors: Karabelli M. Kamel
Published: July 2024

شاع لدى عدد من ثقات الـمُحدّثين قضيّةُ رواية الحديث بالمعنى، وكان من أهم أسباب ذلك هو اعتماد أولئك الـمُحدّثين على حفظِهم، أو تأخيرهم كتابةَ ما سمِعُوه، ولا شَكّ أنه بعد طُول العَهدِ بذلك الـمَسمَوع فربما يَنسَى الـمُحدِّثُ بعض الحروف التي سمعها، فيَستبدِلُها بعبارات أخرى من عنده، تقوم مقام تلك العبارات التي جاءت في الروايات المسموعة. وقد جوّز النُّقّاد مثل ذلك بشروطه، ولم يَعُدّوا ذلك التصرف مُؤثِّرًا في ثقةِ الناقِلِ بالمعنى.
وكان مِن جملة ما وقَع من ذلك للإمام شعبة بن الحَجّاج الحافظ الناقد عبارةٌ أُثِرَت عنه، وهي قولُه: «فكأنه كَرِه ذلك» خلالَ بعض أحاديثه، وقد تبيّن لنا من خلال مقارنة الروايات الأخرى مع روايته أنه يقول ذلك على سبيل الرواية بالمعنى؛ ومن القرائن الدالة على ذلك أن يَروِي غيره الحديث فيذكر اللفظ المسموعَ كما هو، ومن تلك القرائن الدالّة أيضًا أن يَترُك شعبةُ نفسُه تلك العبارةَ أحيانًا، فلا يَذكُرها، ولو كانت هي اللفظَ الـمَسموعَ نفسَه في أصل الرواية لما تَركَه البتّة، ومن قرائن معرفةِ ذلك أيضًا اختلافُ ألفاظِه في التّعبير بذلك، وهي وإن كانت في إطارٍ واحدٍ، إلا أن ذلك التعدُّدَ يَدُلّ على روايتُه لها بالمعنى.
ويُلحَق بمسألة الرواية بالمعنَى: ما يقوله شُعبةُ خلالَ الحديث على سبيل الاستنباط من بعض ألفاظ النبيّ صلى الله عليه وسلم، وسبيل معرفة ذلك يكون ببعض القرائن السابق ذكرها أيضًا.
فكان الهدف من هذا البحث إثبات أن قضية الرواية بالمعنى مما سَوَّغَه النُّقّاد مِن المحدِّثِين، ليس بإقرارهم ذلك من غيرهم مِن الثقات فقط، بل بتَطبيقِهم ذلك بفِعلِهم أنفسِهم.
IMPROVING THE ACCURACY OF CALCULATING THE SUPER-COMPRESSIBILITY COEFFICIENT OF HELIUM BASED ON STATE EQUATIONS

Published: July 2024

To date, the Russian gas industry is developing a large number of deposits with a high helium content in the composition of the extracted gas, such as Chayandinskoye, Kovyktinskoye, Yaraktinskoye oil and gas condensate fields. Helium has never before been the object of detailed study during gathering and treatment, but today helium is an important resource that is used in many fields: military industry, medicine, shipbuilding, laser technology, space technology. The high demand for the component of the extracted gas has created requirements for the creation of a technology for separating it from gas. In addition, helium is a «cold» gas due to the weak interaction of its molecules, so it is difficult to model phase equilibrium at extremely low temperatures. As a result, improving the simulation of condensation of a helium mixture is undoubtedly an urgent task of the industry today. The purpose of the study is to increase the accuracy of calculating the thermodynamic properties of helium based on one of the modifications of the Peng-Robinson equation of state for thermobaric conditions corresponding to helium liquefaction processes.As the methods used in this work, a software module for calculating the selection of the Peneloux correction in the Java programming language was implemented. The results are tested on known experimental data, as well as a specialized software product for calculating the thermodynamic properties of fluids.The features of calculating the superconductivity coefficient of helium based on the cubic equation of state are presented. The optimal range of the Peneloux correction for the Peng-Robinson equation of state has been found, as well as an approximation formula that allows us to find the correction in the low temperature region. The results obtained will allow us to calculate the thermodynamic properties of helium with high accuracy. This will allow us to predict the volume of production and condensation of helium from natural gas, which is certainly an important task for the development of the country's economy.
¿Reinserción social en las cárceles concesionadas? Estudio de caso del Centro de Cumplimiento Penitenciario (CCP) Biobío
Authors: Norambuena-Conejeros Felipe
Published: July 2024

Este artículo expone los resultados de una investigación del año 2022 sobre el modelo de reinserción de la cárcel concesionada CCP Biobío localizado en la región chilena que lleva ese mismo nombre. La investigación se enfoca en un estudio de caso, por medio de la metodología de análisis documental, que examina cómo las políticas y los programas se constituyen en el marco mediante el cual se trabajan los procesos de reinserción social. Dentro de los hallazgos se identificaron serias deficiencias del modelo, que cuestionan la posibilidad de alcanzar la reinserción social en el sistema penitenciario licitado. Ello revela, en primer lugar, la necesidad de realizar ajustes significativos para lograr procesos efectivos de resocialización, además, demuestra cómo la gestión mediante licitación limita la flexibilidad y ralentiza los cambios. Finalmente, se propone redefinir las perspectivas de reinserción al incorporar paradigmas más amplios que involucren la colaboración entre actores gubernamentales, políticas sociales y entidades privadas, como eje fundamental para mitigar el daño que causa la privación de libertad.
