A utilização de produtos químicos pelos jovens continua sendo um problema em todo mundo. O sistema de ensino brasileiro utiliza normas e parâmetros para levar temas sociais importantes para o ambiente escolar, alterando sua forma de abordagem ao longo dos anos. A partir das novas orientações da Base Nacional Comum Curricular (BNCC) sobre o uso abusivo de substâncias químicas, foi investigado o padrão esperado para tratar o tema em ambiente escolar. Levando em consideração que nas últimas décadas o corpo tornou-se alvo de uma atenção redobrada, influenciado pela sociedade de consumo que eleva a importância da aparência corporal, o uso abusivo de esteroides anabolizantes tem sido crescente e gera preocupação, principalmente com jovens, sendo necessária uma atenção especial para prevenção do uso destas substâncias. A política de Redução de Danos, se apresenta como um possível caminho pedagógico para trabalhar a temática educação sobre drogas e mais especificamente os anabolizantes. Nesse caminho, foram avaliados trabalhos que utilizam essa abordagem e sinalizam um caminho promissor para levar temas sensíveis da sociedade para a escola e que contribuam com o ensino, utilizando a educação popular como forma de oportunizar a troca de saberes cotidianos e dialogar com os saberes científicos.

Published: May 2023

Objectives: This study aimed to compare the quality and quantity of bone at intraoral autogenous graft donor sites in type II diabetes mellitus (DM) patients versus healthy controls using cone-beam computed tomography (CBCT). Materials and methods: This case-control study was conducted on CBCT scans of 50 DM patients and 50 healthy controls between 20-70 years. Maximum height, width, length, and volume of harvestable bone at the symphysis, ramus, palate, and tuberosity were measured bilaterally. The Hounsfield unit (HU) was also calculated to assess bone quality. The two groups were compared regarding the quality and quantity of harvestable bone using an independent t-test. The effect of confounders was analyzed by the regression model (alpha = 0.05). Results: DM patients had significantly lower harvestable bone volume at the symphysis, ramus, and tuberosity than healthy controls (p < 0.001) but this difference was not significant at the palate (p = 0.957). Also, bone quality was significantly lower at the symphysis, ramus, palate, and tuberosity in DM patients (p < 0.001). Conclusion: Diabetic patients had significantly lower bone quality and quantity at intraoral graft donor sites than healthy controls. Mandibular symphysis had higher bone volume and density than ramus, palate, and tuberosity for graft harvesting in diabetic patients.

Аналіз відомих методів побудови мережевих стеганографічних каналів передачі даних показав, що технічна можливість використання особливостей протоколів моделі OSI з метою прихованої передачі даних існує в багатьох випадках. Найбільш ефективними методами, є методи, які засновані на протоколах моделі OSI від транспортного рівня і вище, що обумовлюється високою ресурсоємністю їх стегоаналізу. При розробці методу стеганографічної передачі даних основними вимогами стали:  висока скритність процесу передачі повідомлень; достовірність доставки переданих повідомлень; достатня стеганографічна надмірність використаного базового каналу передачі даних; простота реалізації методу. Таким вимогам відповідає протокол транспортного рівня – TCP (Transmission Control Protocol – протокол управління передачею). При використанні протоколів канального та мережевого рівнів моделі OSI, як технологічної основи для організації прихованого каналу передачі даних, приховування здійснюється за рахунок розміщення даних, факт передачі яких повинен бути прихований, у видимих полях заголовків відповідних протоколів, тобто у відкритому вигляді. У зв’язку із тим, що технологія IP-шифрування охоплює лише корисне навантаження протоколів мережевого рівня, то доцільним є використання протоколів транспортного рівня моделі OSI. На даному рівні найпоширенішим є протокол TCP, при цьому він стандартизований і використовується протиборчими сторонами, в тому числі й у військовій сфері. Достовірність доставки повідомлень досягається за рахунок процедури трьохетапного встановлення з'єднання і звітування факту доставки фрагментів. В основу розробленого методу покладено механізм генерації початкового номера послідовності (ISN – Initial Sequence Number) кожного TCP-з'єднання і кореляції байтів переданих (відкритих) даних і байтів повідомлень. Реалізація отриманих результатів забезпечить покращення показників ефективності заходів щодо прихованості управління при передачі даних в інформаційній телекомунікаційній мережі за рахунок розробки стеганографічного методу передачі даних, що використовує особливості протоколів транспортного рівня моделі мережевої взаємодії.

Alloying with nitrogen allows one to substantially increase the strength of steels, especially of the austenitic steels, in which the equilibrium nitrogen content can reach 0.4 – 0.7 wt % depending on their chemical composition. Nitrogen stabilizes austenite and enhances its corrosion and wear resistance. For this reason, nitrogen-containing austenitic steels are advantageous structural materials, in particular, for heavy loaded welded structures. However, wrong choice of the welding method, regime, or filler for high-nitrogen steels can cause critical defects such as pores and cracks in the welded joints and substantially decrease their mechanical properties and corrosion resistance compared to those of the base metal. More than hundred literature sources have been considered for the analysis of welding types and methods for austenitic steels containing ≥ 0.4 wt. % nitrogen, the criteria for their weldability, and the causes for potential negative phenomena occurring upon their welding. For such steels, information is provided on the welding filler materials as well as on the modes and parameters of the welding process (supplied heat, presence/absence of a protective atmosphere, its composition, etc.). The structure, phase composition, and properties of the resulting welded joints are considered. The examples are given on the effect of the subsequent processing of welded joints (heat treatment and thermal deformation processing for the elimination of the resulting distortion) on their basic properties.

Using X-ray photoelectron spectroscopy, the change in the chemical composition of the polyketon films surface as a result of treatment by the low-pressure direct current discharge was studied. The films were placed at the anode and cathode, and filtered atmospheric air was used as the working gas. The formation of a significant amount of oxygen-containing groups on the polymer surface was shown. Using atomic force microscopy, it was found that plasma treatment leads to a significant increase in the surface roughness of the films. Such changes improve the contact and adhesion properties of polyketon films.

The carbon material was synthesized from polymer raw materials (MC-032). He MC-032 has been characterized by various methods, including N2 adsorption-desorption at 77 K, X-ray diffraction analysis, Fourier transform IR spectroscopy, and Raman spectroscopy. The resulting adsorbent has a well-developed porous structure (SBET = 2722 m2/g; VDFT = 1.08 cm3/g). The adsorption of methane was studied in a wide range of pressures at temperatures above the critical one. The maximum adsorption value is ~ 14 mmol/g at 298.15 K and 100 bar. Experimental data on methane adsorption on MC-032 were analyzed using the Dubinin–Radushkevich adsorption model in the temperature range 298.15 – 323.13 K and pressures up to 100 bar. It has been established that the average relative deviations between the experimental results and the results obtained using the Dubinin-Radushkevich model are less than 4 %. It is shown that the differential molar heats of methane adsorption decrease from ~ 25 to ~ 10 kJ/mol. The calculated characteristic adsorption energies are in the range of 5.88 – 6.21 kJ/mol, which indicates that the process of methane adsorption on MC-032 belongs to physical adsorption. MC-032 carbon material has strong adsorption capacity for methane and has good prospects for controlling methane emissions and reducing greenhouse gases.

The features of the formation of the microstructure of welded joints of sheets of aluminum alloy V-1381 of the Al – Mg – Si – Cu system, obtained with various parameters of automatic argon-arc welding, were studied. Welding modes were selected that provide a high-quality welded joint and strength at a level not lower than 0.8 of the strength of the base metal. It has been established that welding without filler wire leads to cracking without applying tensile deformation, the use of Sv1221 filler wire compared to SvAMg61 and SvAK5 leads to an increase in the strength characteristics of welded joints by 15 – 20 %. Corrosion resistance of welded joints of sheets from V-1381 alloy was determined. Various experimental modes of laser welding were tested, the microstructure and mechanical properties of welded joints were studied. Parameters have been selected that ensure high quality of welds. The possibility of using laser welding for semi-finished products from alloy V-1381 has been established. The new V-1381 alloy can be recommended for use in aircraft fuselage structural elements, including as an alternative to less corrosion-resistant non-weldable alloys of the D16 type, which will increase the weight efficiency of structures both due to increased strength and through the use of welded joints instead of riveted ones.

The mathematics teacher and curriculum change

Authors: Kilpatrick Jeremy
Published: April 2023

One of the most compelling lessons of the new math reform era —from the mid 1950s to the mid 1970s— concerned the pivotal role of the mathematics teacher in effecting curriculum change. Recent efforts to change the school mathematics curriculum are rediscovering that old lesson: The teacher is the key to change. Consequently, when teachers are confronted with arguments against the direction that proposals for curriculum change are taking, it is important for them to analyze and discuss the proposed changes. Recent experiences in the United States, which does not have the same centralized curriculum organization as Portugal but which is experiencing some of the same proposals and arguments against them, may be helpful in understanding the role that teachers can play in the social process of creating a curriculum. El profesor de matemáticas y el cambio de currículo Una de las lecciones más destacadas extraídas de la era de la reforma de la matemática moderna hacía referencia al papel esencial que el profesor de matemáticas desempeñaba en el cambio del currículo. Los recientes esfuerzos por cambiar el currículo de las matemáticas escolares están redescubriendo esta vieja lección: El profesor es la clave para el cambio. Consecuentemente, cuando los profesores argumentan en contra de las propuestas de cambio curricular, es importante que analicen y discutan los cambios propuestos. Las experiencias recientes en Estados Unidos, donde no existe la misma organización curricular centralizada de Portugal pero que experimenta parte de las mismas propuestas y argumentos contra ellas, puede ser útil para comprender el papel que los profesores pueden jugar en el proceso social de creación de un currículo.Handle: http://hdl.handle.net/10481/3511Nº de citas en WOS (2017): 8 (Citas de 2º orden, 7)Nº de citas en SCOPUS (2017): 9 (Citas de 2º orden, 27)

We are examining actions that teachers take to convert tasks into learning opportunities. In this paper, we contrast ways that three teachers convert the same task into lessons, and the way that their lessons reflect their intent. We found that the teachers did what they intended to do, that this was connected to their appreciation of the mathematics involved, and directly influenced the learning opportunities of the students. To the extent that the potential of the task was reduced, this seemed due to the lack of mathematical confidence in the case of two of the teachers. Exploración de las relaciones entre tarea, acciones del profesor y aprendizaje del estudiante Examinamos las acciones que los profesores llevan a cabo para convertir tareas en oportunidades de aprendizaje.

Encontramos que los profesores hicieron lo que pretendían hacer, que esto estaba relacionado con su percepción de las matemáticas que estaban implicadas y que esta relación influyó directamente en las oportunidades de aprendizaje de los estudiantes. En el caso de dos profesores, la reducción en el potencial de la tarea parece deberse a su falta de confianza matemática.Handle: http://hdl.handle.net/10481/4449Nº de citas en WOS (2017): 2 (Citas de 2º orden, 0)Nº de citas en SCOPUS (2017): 7 (Citas de 2º orden, 9)

Kur’ân’ı anlama ve hayata geçirme faaliyeti ilk dönemde anlama ve uygulama olarak müslümanlar arasında cereyan etmiş, ilerleyen dönemde Kur’ân âyetlerinin kast ettiği manalar ve bunların yorumlarına dair anlayış ve bilgi birikimi yazıya aktarılmıştır. Zamanla yaygınlaşan ve sistemleşen bu birikim tefsir ilmi olarak adlandırılmıştır. Geçmişten günümüze tefsir ilmine dair yapılan çalışmalar neticesinde elimizde son derece büyük bir külliyat bulunmaktadır ve bu alana dair çalışmalar günümüzde de tüm yoğunluyla devam etmektedir. İslam’ın farklı coğrafyalarda ve bu coğrafyada yaşayan farklı kültürlerden insanlar arasında yayılmaya başlaması tefsir ilmini de etkilemiştir. Farklı kültürlere ve farklı bilgi birikimlerine sahip müslümanların Kur’ân’a yaklaşımları, onu algılamaları ve açıklamaları da farklı olmuş ve böylece âyetlerin ifade ettiği anlamlar farklı açılımlar kazanmıştır. On dört asrı aşkın bir süreç içerisinde oluşan bu tefsir birikimi, günümüz tefsir çalışmaları açısından da son derece önemlidir. Nitekim geçmişte Kur’ân’ın hangi dönemde, hangi şartlar altındaki müslümanlar tarafından nasıl anlaşıldığını ve onların kendi dönemlerindeki problemlere Kur’ân’dan nasıl cevaplar bulduklarını bilmek, günümüzde Kur’ân’ın anlaşılmasına ışık tutan önemli bir konumdadır. İslam tarihinin neredeyse yarısına tekabül eden yaklaşık altı yüzyıllık bir dönemde geniş bir coğrafyada hüküm süren ve bu süreçte müslümanların en büyük gücünü temsil eden Osmanlı Devleti döneminde de tefsir ilmine dair pek çok eser telif edilmiştir. Bu çalışmada Osmanlı Devleti’nin son ve Türkiye Cumhuriyeti’nin ilk yıllarında yaşamış olan Osmanlı âlimi ve müderrisi Sivaslı Hacı Mehmet Necip Efendi’nin (ö. 1347/1929) hayatı ve eserlerine yer verildikten sonra kendisinin kaleme aldığı Aʿẓamü’t-Taʿẓîmât fî Tefsir-i Sûreti’l-Ḥucurāt adlı tefsîrinin yazma nüshasının latin harflerine aktarımı yapılacak ve sonuç bölümünde eserle ilgili değerlendimelerde bulunulacaktır. Mehmet Necip Efendi hakkında yapılan çalışmalarda ve kendisinden bahsedilen birtakım eserlerde bu çalışmaya konu olan tefsirden hiç bahsedilmemiş olması, makalenin özgünlüğünü ortaya koymaktadır.
Differential expression of NAMPT in cancer of the cervix.
Authors: Mamoor Shahan
Published: May 2023

Almost all cervical cancers are caused by infection with high-risk human papillomaviruses (HPVs) (1-3); the transcriptional features that distinguish the gene expression programs of HPV-induced cancers from that of cancers resulting from non-viral abrogation of tumor suppression remain incompletely defined. We mined published and public microarray datasets (4, 5) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with the most common type of cervical cancer, cervical squamous cell carcinoma. We found significant differential expression of the gene encoding nicotinamide phosphoribosyltransferase, NAMPT, when comparing tumor tissue from the human cervix to the tissue of origin. NAMPT mRNA was present at significantly higher quantities in tumors of the cervix as compared to normal tissues from the cervix. Analysis of human survival data revealed that expression of NAMPT in tumors of the cervix was correlated with overall survival in patients with cervical cancer. NAMPT expression changes may be important for the initiation or progression of cancer of the cervix in humans.

Attentional Scope and Atomic Energy Levels: An Analogical Comparison.
Authors: Dolatabadi Mohsen
Published: May 2023

The article draws an analogical comparison between the electron arrangement in atoms and the attentional scope in human cognition. The Bohr atomic model and the orbital levels in quantum mechanics are compared to the different stages or levels of information processing in the brain. The contraction and expansion of attentional scope are related to the movement of electrons between energy levels in atoms. The abstractness of language is compared to the energy level of electrons near the valence level of particles. Finally, the concept of electropositivity in atoms is related to sociability in human interaction, while the effect of positive mood states on the cognitive scope is analogized to the behaviour of electrons across atoms or Ion radius.

Differential expression of ISLR in cancer of the cervix.
Authors: Mamoor Shahan
Published: May 2023

Almost all cervical cancers are caused by infection with high-risk human papillomaviruses (HPVs) (1-3); the transcriptional features that distinguish the gene expression programs of HPV-induced cancers from that of cancers resulting from non-viral abrogation of tumor suppression remain incompletely defined. We mined published microarray datasets (4, 5) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with the most common type of cervical cancer, cervical squamous cell carcinoma. We found significant differential expression of the gene encoding immunoglobulin superfamily-containing leucine-rich repeat, ISLR, when comparing tumor tissue from the human cervix to the tissue of origin. ISLR mRNA was present at significantly lower quantities in tumors of the cervix as compared to normal tissues from the cervix. Analysis of human survival data revealed that expression of ISLR in tumors of the cervix was correlated with overall survival in patients with cervical cancer. ISLR expression changes may be important for the initiation or progression of cancer of the cervix in humans.
Keynote prescription in children in common ailments with the aid of repertory.
Authors: Verma Anurag
Published: May 2023

During early days repertory was not so advance. There was an urgent need ofadopting an easy, simple quick method to choose similimum or near to similimum.Dr.H.N.Guernsey, an American homoeopath, observed certain symptoms in each medicinewhich were present in most of the provers or cases and were the main stem of the medicine around which all symptoms revolve. It is practically impossible to exactly match the thousand symptoms of medicines with patient’s symptoms, moreover, all symptoms are not presented by the patient at a given time. At present time there are more than five thousand medicines so wehave to choose a repertory even for keynote prescribing.

Differential expression of SMARCD3 in cancer of the cervix.
Authors: Mamoor Shahan
Published: May 2023

Almost all cervical cancers are caused by infection with high-risk human papillomaviruses (HPVs) (1-3); the transcriptional features that distinguish the gene expression programs of HPV-induced cancers from that of cancers resulting from non-viral abrogation of tumor suppression remain incompletely defined. We mined published microarray datasets (4, 5) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with the most common type of cervical cancer, cervical squamous cell carcinoma. We found significant differential expression of the gene encoding SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily d, member 3, SMARCD3, when comparing tumor tissue from the human cervix to the tissue of origin. SMARCD3 mRNA was present at significantly lower quantities in tumors of the cervix as compared to normal tissues from the cervix. Analysis of human survival data revealed that expression of SMARCD3 in tumors of the cervix was correlated with overall survival in patients with cervical cancer: this correlation was positive in patients whose tumors were relatively depleted of regulatory T cells, while it was negative in patients whose tumors were relatively enriched with regulatory T cells. SMARCD3 expression changes may be important for the initiation or progression of cancer of the cervix in humans.
Exploring chemistry Language through the Framework of Cognitive Grammar01
Authors: Dolatabadi Mohsen , کامبوزیا عالیه کرد زعفرانلو
Published: May 2023

Cognitive Grammar can be applied to better understand the language used to describe chemistry by analyzing prepositional meanings, roles of trajectors, cognitive metaphors, concepts of thing and relation, immediate scope, and prototypes. The ideas of elaboration and extension show that language is crucial for developing and communicating scientific concepts in chemistry. Overall, the framework of Cognitive Grammar can enhance communication and understanding in chemistry. Here we present some innovative ideas for processing chemistry based on cognitive Grammar.
When Half is At Least 50%: Effect of “Framing” and Probability Level on Frequency Estimates
Authors: Mandel David R. , Kelly Megan O.
Published: May 2023

Expert judgment often involves estimating magnitudes, such as the frequency of deaths due to a pandemic. Three experiments (Ns = 902, 431, and 755, respectively) were conducted to examine the effect of outcome framing (e.g., half of a threatened group expected to survive vs. die), probability level (low vs. high), and probability format (verbal, numeric, or combined) on the estimated frequency of survivals/deaths. Each experiment found an interactive effect of frame and probability level, which supported the hypothesis that forecasted outcomes received by participants were implicitly quantified as lower bounds (i.e., “at least half”). Responding in a manner consistent with a lower-bound “at least” interpretation was unrelated to incoherence (Experiments 1 and 2) and positively related to numeracy (Experiments 1 and 3), verbal reasoning (Experiment 3), and actively open-minded thinking (Experiment 2 and 3). The correlational results indicate that implicit lower bounding is an aspect of linguistic inference and not a cognitive error. Implications for research on framing effects are discussed.
The P300, the LPP, context updating, and memory: What is the functional significance of the emotion-related late positive potential?
Authors: Fields Eric C
Published: April 2023

The emotion-related late positive potential (LPP) of the event-related potential (ERP) has been the topic of many studies over the previous two decades, but the function of this component (the cognitive process that it reflects) is very much an open question. In this paper, I build on frameworks that suggest a close relationship between the LPP and the P300 component of the ERP to argue that the classic context updating account of the P300 may provide insights into the function of the LPP. I then review broader connections between the LPP and memory, and I connect the LPP to research and theory in the area of emotional memory. I argue that while a relationship between the LPP and attention has been widely noted in the literature, connections to memory have been overlooked and that a memory-related process should be considered as one candidate for the function of the LPP.
Self-Censorship Appears to be an Effective Way of Reducing the Spread of Misinformation on Social Media

There is increasing pressure on social media companies to reduce the spread of misinformation on their platforms. However, they would prefer not to be the arbiters of truth as the truth can be subjective or otherwise hard to determine. Instead, they would prefer that social media users themselves show better discernment when deciding which information to share. Here we show that allowing people to share only those social media posts that they have indicated are true significantly improves sharing discernment, as measured by the difference in the probability of sharing true information versus the probability of sharing false information. Because it doesn’t require social media companies to be the arbiters of truth, this self-censorship intervention can be employed in situations where social media companies suspect that individuals are propagating misinformation but are not sufficiently confident in their suspicions to directly censor the individuals involved. As such, self-censorship can usefully supplement externally imposed (i.e. traditional) censorship in reducing the propagation of false information on social media platforms.

Published: May 2023

The purpose of this meta-analytic review is to investigate the relation between statisticallearning (SL) and language-related outcomes, and between SL and reading-related outcomes. Acomprehensive search of peer-reviewed published research resulted in 42 articles with 53independent samples and 201 reported effect sizes (Pearson’s r). Results of our robust varianceestimation correlated effects model revealed a significant, moderate relation between SL andlanguage-related outcomes, r = 0.236, p < .001, and a significant, moderate relation between SLand reading-related outcomes, r = 0.239, p < .001. Moreover, age, the writing system of thelanguage, and SL paradigm moderate the strength of the association between SL and reading.Age is the only significant moderator on the strength of the association between SL andlanguage. The findings from this meta-analysis shed light on the contribution of multiple factorsthat impact how SL relates to language and reading outcomes, with important implications fordeveloping effective instructional practices that emphasize statistical regularities of oral andwritten materials in the classroom. Theoretical implications of these findings for language andreading development are discussed.
CONTROLLING WATER LEVEL BY USING MODIFIED MODEL FREE ADAPTIVE CONTROLLER
Authors: Mohammed Yousra Abd , H. Karam Ekhlas , N. Kadhim Nahida
Published: May 2023

This paper investigates a simple mathematical model for a water level system, which consists of a DC motor (water pump), and a Speed to Height transformation block, that relates the speed of the motor, to the height of the water level. The input signal is the applied voltage to the armature of the DC motor, while the output signal is the rotational speed of the shaft.  A simple modified model-free adaptive controller is suggested, to control the level of water, by adjusting the rate of the incoming water flow to the container, by changing the speed of the water pump, that fills the container. The suggested controller consists of a conventional model free adaptive controller, combined with the proportional integral derivative controller. The parameters of the controller are tuned using two methods. The overall controlled water level system is simulated through MATLAB R2015a software. The results show the efficiency of the suggested controller, when compared to the tuned PID and the MFAC, due to its least fluctuation peak, fast response with a small settling time, and zero steady-state error.

Published: April 2023

Since the emergence of the internet and open science in the 1990s, “predatory journals,” or “predatory publishing,” have attracted the increasing attention of scholars. Research on the topic has grown at a rapid rate, particularly in the last five years. This article serves as the first bibliometric review on the topic of “predators in the scientific publication” and draws on 869 published articles from the Scopus database between 2012 and 30 March 2022. These papers were produced by a total of 1586 authors, coming from 101 countries, representing 1538 organizations, and published in 501 journals. Research disciplines mostly covered the fields of medicine, social sciences, and nursing. This study also reveals the complexity of issues and research trends around the topic of predatory scientific publications, including the review process for scientific journals, publication fees and article processing charges, open science and open-access publications, and the like and related topics such as the impact on scholars in developing countries and academic ethics. Finally, this article provides several recommendations, namely, the need for more efficient criteria to evaluate the quality of scientific journals, more public communication on the importance of ethics in research and publication, and a greater awareness among scholars and organizations of the implications of the “predator” issue in scientific publishing.
