Identidad escolar y la diferencia: una apuesta desde el PEI para pensar los procesos de inclusión
Authors: Mosquera Mosquera Carlos Enrique , Ramírez-Martínez Jorge Enrique
Published: August 2021

Este artículo deviene de los diálogos entre pares y disertaciones de la tesis doctoral titulada El proyecto educativo institucional y la formación de la subjetividad política para un escenario de posconflicto: memoria colectiva del conflicto armado e identidad escolar. Su objetivo consiste en pensar la identidad escolar reconociendo la diversidad de la subjetividad en el marco de los procesos educativos, teniendo en cuenta el proyecto educativo institucional (PEI). La metodología elegida fue la historia oral, y como enfoque se optó por el hermenéutico. Un hallazgo sobresaliente fue la necesidad de que la escuela instaure procesos educativos con asiento en el PEI, respetando la diferencia y la diversidad de la subjetividad y evitando la ceguera pedagógica y administrativa. Cuando la escuela se aleje de modelos y metodologías totalizantes, y cuando maestros y directivos diversifiquen sus prácticas, la verdadera identidad escolar se configurará en el alumno cuando este sienta el deseo de adscripción a la escuela, dadas la acogida que recibe y las experiencias que vivencia en su interior. Se necesita que la escuela tenga una comprensión amplia del alumnado a partir de los principios lógicos de exclusión e inclusión, porque el alumno es logo-razón, pero también un ser instintivo.
El rol docente en la atención a la diversidad en Chile
Authors: Silva-Cid Elena
Published: August 2021

Se observan contradicciones entre las máximas educativas chilenas, el marco legal, el currículum y la evaluación que se realiza para establecer grados de calidad y ordenación de las escuelas. En los cuerpos legales se establece la importancia del reconocimiento, la valoración y la atención de la diversidad, pero el sistema funciona a partir de un currículum homogeneizante y de evaluaciones altamente estandarizadas. La brecha en los resultados obtenidos entre los grupos socioeconómicos altos y los más desposeídos evidencia que la calidad en educación no se alcanza para todos en la misma medida. En este contexto, se buscar reflexionar sobre la importancia del rol docente en la atención a la diversidad. El profesorado puede, a partir de un desempeño caracterizado por la autonomía y la responsabilidad profesional, considerar el capital cultural del alumnado como una riqueza posible de incorporar al currículum escolar y al trabajo docente en aula. El profesorado puede acercar el currículum al estudiantado y hacerlo pertinente; sin embargo, la evidencia muestra que la práctica docente en Chile se caracteriza por un desempeño centrado en el currículum oficial que desconoce las particularidades del alumnado.

Published: August 2021

Background:

Hydrophilic Hydroxypropyl Methylcellulose (HPMC) matrix tablets are
the standard role model of the oral controlled-release formulation. Nevertheless, the HPMC kinetics
for the mechanistic understanding of drug release and hydrodynamic behaviors are rarely investigated.
This study aims to investigate the release behaviors of both HPMC and paracetamol
(model drug) from the hydrophilic matrix tablet.

Methods:

Two different viscosity grades of HPMC were used (Low viscosity: 6 cps, High viscosity:
4,000 cps). Three different ratios of drug/HPMC (H:38.08%, M:22.85%, and L:15.23% (w/w)
of HPMC amounts in total weight) matrix tablets were prepared by wet granulation technique. The
release profiles of the drug and HPMC in a matrix tablet were quantitatively analyzed by HPLC
and 1H-Nuclear Magnetic Resonance (NMR) spectroscopy. The hydrodynamic changes of HPMC
were determined by the gravimetric behaviors such as swelling and erosion rates, gel layer thickness,
front movement data,and distributive Near-Infrared (NIR) chemical imaging of HPMC in a
matrix tablet during the dissolution process.

Results:

High viscosity HPMC tablets showed slower release of HPMC than the release rate of
drug, suggesting that drug release preceded polymer release.Different hydration phenomenon was
qualitatively identified and corresponded to the release profiles. The release behaviors of HPMC
and drug in the tablet could be distinguished with the significant difference with fitted dissolution
kinetics model (Low viscosity HPMC 6cps; Korsmeyer-Peppas model, High viscosity HPMC
4000cps; Hopfenberg model, Paracetamol; Weibull model) according to the weight of ingredients
and types of HPMC.

Conclusion:

The determination of HPMC polymer release correlating with drug release, hydrodynamic
behavior, and NIR chemical imaging of HPMC can provide new insights into the drug release-
modulating mechanism in the hydrophilic matrix system.

Published: August 2021

Introduction:

Dementia becomes a major public health challenge in both the Czech Republic
and worldwide. The most common form of dementia is Alzheimer’s disease (AD).

Objective:

We conducted two successive epidemiological projects in 2012-2015 and 2016-2019. Their
aim was to study the effect of selected potential genetic, vascular and psychosocial risk factors on the
development of AD by comparing their frequencies in AD patients and controls.

Methods:

Epidemiological case-control studies were conducted. In total, data from 2106 participants
(1096 cases, 1010 controls) were analyzed.

Results:

Three times more females than males suffered from AD. The highest proportion of cases were
those with primary education, unlike controls. There were statistically significantly more manual
workers among cases than among controls. Of selected vascular risk factors, coronary heart disease
was found to be statistically significantly more frequent in cases than in controls. The onset of hypertension
and diabetes mellitus was earlier in controls than in cases. As for hobbies and interests, there
were statistically significant differences in physical activity, reading and solving crosswords between
the groups, with these activities being more common in controls.

Conclusion:

The prevalence of chronic neurodegenerative diseases, in particular AD, is currently increasing.
Given the aging of the population, these conditions may be expected to rise in prevalence.
Potential risk of AD needs to be studied, analyzed and confirmed; a detailed knowledge of the risks of
AD and early detection of the pathology may therefore be very beneficial for prevention and early
treatment of this condition.

Authors: Katoch G.
Published: August 2021

Many researchers are interested in investigating ceramic materials because of the potential for their use in nanotechnology. Spinel ferrites are a diverse group of materials with many applications. Electronic devices such as inductors, power, information storage, microwave, and induction tuners are only a few examples. As ferrite materials exhibit super-paramagnetic activity, their potential for biological applications such as drug delivery, hyperthermia, and resonance magnetic imaging. As a result, super-paramagnetism is a highly desirable property in spinel ferrites. Due to the size dependence, the methodologies used to synthesis of these materials have emerged as a critical step in achieving the desired properties. Many synthesis strategies have been developed in this regard such as sol-gel, co-precipitation, solid-state, solution combustion method and so on. As a result, this study provides a historical overview of spinel ferrites, as well as key principles for comprehending their various characterization techniques and properties. Recent developments in the synthesis and applications of spinel ferrites are also discussed.

Authors: Kaur A.
Published: August 2021

Nanotechnology, when this word comes in mind, it gives deep thought of new development in communication, medical science, intelligent transport system and many more. Ferrites nanoparticles have great significance owing to their amazing chemical and physical properties. In modern era we are developing materials for microwave applications and communication devices. Before the discovery of semiconductor memory chips, ferrites were the major form for electronic memory used in computers. Scientist have been studying and working with nanoparticles in magnetically guided drug delivery. The reactivity of material increases by the use of nanoparticles of that material. The dielectric characteristics of ferrites lean on diverse factors for instance methods of preparations and chemical composition. In various studies it has been found that their conductivity has dependence on temperature, composition and frequency. Among the various kinds of ferrites, Ni–Zn ferrites are viewed as the most adaptable ferrites as a result of their novel characteristics for applications at high frequency. The Ni-Zn ferrites are exploited as core materials in a variety of EM devices as well as have broad range of industrial applications e.g. inductors, microwave devices, power supplies, high and low frequency transformer cores, electromagnetic interference (EMI) suppressions and antenna rods. These broad ranges of applications are owing to their high resistivity, low eddy currents, high saturation magnetization, chemical stability and high Curie temperature. In view of this, the present chapter deals with the research progress on nickel-zinc ferrites in the bulk as well as nano size.

Authors: Verma R.
Published: August 2021

The wurtzite structured materials possess the inner-crystal piezopotential which comprehensively tune or control the charge carrier generation, separation, transportation, and recombination in optoelectronic devices. The piezo-phototronic effect provides a new working principle to the current traditional devices. Its effect on solar cells progresses made by the eminent scientists, and researchers in the field of piezo-phototronic modulated solar cells such as semiconductor-based, perovskite-based, multiple quantum-well (MQW) based and core/shell based. It has been described that the piezo-phototronic effect has improved the power conversion efficiency (PCE) of the solar cells, and the effect of temperature on the piezo-phototronic devices. Ferrite-based materials have emerged as a viable candidate for use in solar cells. As a result of this research, ferrite-based nanomaterials can now be used in solar cell applications, as well as the piezophototronic effect on these materials can be investigated. The piezo-phototronic effect is a novel subject that offers a new platform for material science and electronics to investigate.

Burden and Help-Seeking Behaviors Linked to Problem Gambling and Gaming: Observational Quantitative and Qualitative Analysis
Authors: Luquiens Amandine , von Hammerstein Cora , Benyamina Amine , Perney Pascal
Published: August 2021

Background

Models based on the uniqueness of addiction processes between behavioral addictions are highly contentious, and the inclusion of gaming disorder in the addiction nosography remains controversial. An exploratory approach could clarify a hypothesized common and subjectively identifiable process in addictive behaviors and the necessarily different expressions of the disorder due to behavior specificities, in particular the sociocultural characteristics and profiles of users.

Objective

The aim of this study was to describe the nature of contacts to a help service by exploring commonality and specificities of burden and help-seeking for problem gambling or gaming.

Methods

This was an observational quantitative-qualitative study. We included all contacts (ie, online questions and contacts by phone or chat when the helper completed a summary) to a helpline for gamers, gamblers, and relatives over a 7-year period. We constituted a text corpus with online questions and summaries of contacts by phone or chat. We collected basic sociodemographic data, including the device used to contact the service (phone or internet), contacting the service for oneself (“user”) or being a relative of a user and type of relative, gambling (yes/no), gaming (yes/no), and age and sex of the gambler/gamer. We describe the corpus descriptively and report the computerized qualitative analysis of online questions, chat, and summary of phone calls. We performed a descendant hierarchical analysis on the data.

Results

A total of 14,564 contacts were made to the helpline, including 10,017 users and 4547 relatives. The corpus was composed of six classes: (1) gaming specificities, (2) shared psychological distress and negative emotions, (3) the procedure for being banned from gambling, (4) the provided help, (5) gambling specificities, and (6) financial problems.

Conclusions

Negative emotions and shared distress linked to gambling and gaming support current scientific consensus that these behaviors can produce psychological distress in se; however, meaningful differences were observed in core symptoms of addiction between gamers and gamblers, beyond specificities related to the behavior itself: loss of control was elicited in the class corresponding to gambling specificities and not by gamers and their relatives.
COVID-19 and Vitamin D Misinformation on YouTube: Content Analysis (Preprint)
Authors: Quinn Emma K , Fenton Shelby , Ford-Sahibzada Chelsea A , Harper Andrew , Marcon Alessandro R , Caulfield Timothy , Fazel Sajjad S , Peters Cheryl E
Published: August 2021

BACKGROUND

The “infodemic” accompanying the SARS-CoV-2 virus pandemic has the potential to increase avoidable spread as well as engagement in risky health behaviors. Although social media platforms, such as YouTube, can be an inexpensive and effective method of sharing accurate health information, inaccurate and misleading information shared on YouTube can be dangerous for viewers. The confusing nature of data and claims surrounding the benefits of vitamin D, particularly in the prevention or cure of COVID-19, influences both viewers and the general “immune boosting” commercial interest.

OBJECTIVE

The aim of this study was to ascertain how information on vitamin D and COVID-19 was presented on YouTube in 2020.

METHODS

YouTube video results for the search terms “COVID,” “coronavirus,” and “vitamin D” were collected and analyzed for content themes and deemed useful or misleading based on the accuracy or inaccuracy of the content. Qualitative content analysis and simple statistical analysis were used to determine the prevalence and frequency of concerning content, such as confusing correlation with causation regarding vitamin D benefits.

RESULTS

In total, 77 videos with a combined 10,225,763 views (at the time of data collection) were included in the analysis, with over three-quarters of them containing misleading content about COVID-19 and vitamin D. In addition, 45 (58%) of the 77 videos confused the relationship between vitamin D and COVID-19, with 46 (85%) of 54 videos stating that vitamin D has preventative or curative abilities. The major contributors to these videos were medical professionals with YouTube accounts. Vitamin D recommendations that do not align with the current literature were frequently suggested, including taking supplementation higher than the recommended safe dosage or seeking intentional solar UV radiation exposure.

CONCLUSIONS

The spread of misinformation is particularly alarming when spread by medical professionals, and existing data suggesting vitamin D has immune-boosting abilities can add to viewer confusion or mistrust in health information. Further, the suggestions made in the videos may increase the risks of other poor health outcomes, such as skin cancer from solar UV radiation.

Authors: Mupfururirwa Wilson , Nembaware Victoria , Morrice Jack , Mnika Khuthala , Mazandu Gaston Kuzamunu , Wonkam Ambroise
Published: August 2021

BACKGROUND

The impact of mobile phones and their applications in healthcare (mobile health) is well established for a range of diseases and cross-cutting complications, such as pain. While numerous mobile health (mHealth) pain interventions have been established, an evaluation of their prevalence, adequacy and distribution remains limited.

OBJECTIVE

This study aims at reviewing and comparing current pain management mHealth tools in high- versus low-income countries.

METHODS

A literature and application (app) store search was conducted in May 2021 using combinations of the following keywords: “pain management”, “pain”, “mobile health”, “telemedicine”, and “app”. Literature searches were conducted in PubMed, Scopus, Cochrane Review Library, and Google scholar. App store searches were conducted in Google Play and Apple App Store. Data characteristics descriptive analysis was performed using R software to summarize different datasets and compute p-values (P) for testing the significance of different hypotheses with the significance level set to 0.05.

RESULTS

The search identified 40 publications (literature search) and 230 mHealth applications (app store search), revealing a non uniform distribution of search categories (χ2= 133.7, P < 0.004) with a ratio approximating 1:6 (OR = 5.730, 95%CI:3.745-8.909, P < 0.004). About 86.7% of these 270 applications (apps) are from high-income countries, showing a statistically significant non uniform distribution of country categories: high- and low-income (χ2= 145.2, P < 0.004) approximating the theoretical distribution of a 7:1 ratio (OR = 6.476, 95%CI:4.180-10.222, P < 0.004). Moreover, there is no significant difference in the proportion of search categories between country categories ( χ2= 0.113, P = 0.737) and the difference in pain app prevalence in high- versus low-income countries is not statistically significant. Finally, we have observed that pain-tracking apps are significantly more prevalent in developed countries in comparison to low-income countries.

CONCLUSIONS

As expected, pain management app prevalence is higher in high-income countries. However, more research is required to readily comprehend the effectiveness of these apps.

The platform has been piloted and tested by health departments in four European countries, each focusing on different region-specific health challenges and related data sources.

RESULTS

A novel health data platform solving the needs of Public Health decision-makers was successfully implemented within the four pilot regions connecting heterogeneous healthcare datasets and open datasets and turning large amounts of previously isolated data into actionable information allowing for evidence-based health policy-making and risk stratification through the application and visualization of advanced analytics.

CONCLUSIONS

The MIDAS platform delivers a secure, effective and integrated solution to deal with health data, providing support for health policy decision-making, planning of public health activities and the implementation of the Health in All Policies approach. The platform has proven transferable, sustainable and scalable across policies, data and regions.
Exploring Older Adults’ Adoption and Use of a Tablet Computer During COVID-19: Longitudinal Qualitative Study (Preprint)
Authors: Kim Sunyoung , Yao Willow , Du Xiaotong
Published: August 2021

BACKGROUND

As mobile computing technology evolves, such as smartphones and tablet computers, it increasingly offers features that may be particularly beneficial to older adults. However, the digital divide exists, and many older adults have been shown to have difficulty using these devices. The COVID-19 pandemic has magnified how much older adults need but are excluded from having access to technologies to meet essential daily needs and overcome physical distancing restrictions.

OBJECTIVE

This study sought to understand how older adults who had never used a tablet computer learn to use it, what they want to use it for, and what barriers they experience as they continue to use it during social isolation caused by the COVID-19 pandemic.

METHODS

We conducted a series of semistructured interviews with eight people aged 65 years and older for 16 weeks, investigating older novice users’ adoption and use of a tablet computer during the nationwide lockdown due to COVID-19.

RESULTS

Participants were gradually yet successfully accustomed to using a tablet computer to serve various daily needs, including entertainment, social connectedness, and information-seeking. However, this success was not achieved through developing sufficient digital skills but rather by applying the methods they were already familiar with in its operation, such as taking and referring to instruction notes.

CONCLUSIONS

Our findings imply that older adults without digital literacy can still benefit from a digital device for quality of later life if proper traditional methods they are already familiar with are offered in its use.
Natural Language Processing Accurately Categorizes Indications, Findings and Pathology Reports From Multicenter Colonoscopy (Preprint)
Authors: Vadyala Shashank Reddy , Sherer Eric A.
Published: August 2021

BACKGROUND

Colonoscopy is used for colorectal cancer (CRC) screening. Extracting details of the colonoscopy findings from free text in electronic health records can be used to determine patient risk for CRC and colorectal screening strategies. We developed a deep learning model framework to extract information for the clinical decision support system to interpret relevant free-text reports, including indications, pathology, and findings notes.

OBJECTIVE

We developed and evaluated the accuracy of a deep learning model framework to extract information for the clinical decision support system to interpret relevant free-text reports, including indications, pathology, and findings notes.

METHODS

The Bio-Bi-LSTM-CRF framework was developed using Bidirectional Long Short-term Memory (Bi-LSTM) and Conditional Random Fields (CRF) to extract several clinical features from these free-text reports including indications for the colonoscopy, findings during the colonoscopy, and pathology of resected material. We trained the Bio-Bi-LSTM-CRF and existing Bi-LSTM-CRF models on 80% of 4,000 manually annotated notes from 3,867 patients. These clinical notes were from a group of patients over 40 years of age enrolled in four Veterans Affairs Medical Centers. A total of 10% of the remaining annotated notes were used to train hyperparameter and the remaining 10% were used to evaluate the accuracy of our model Bio-Bi-LSTM-CRF and compare to Bi-LSTM-CRF.

RESULTS

Bio-Bi-LSTM-CRF test set accuracy was 93.5% for indications reports, 88.0% for findings reports, 96.5% for pathology reports, 85.0% for number of polyps’ entity, 81.0% for size of polyps’ entity, 94.0% for locations of polyps entity, and 92.0% for poly removal procedure entity, and 96.5% for colon location of polyps. The accuracy of the Bio-Bi-LSTM-CRF methods between facilities ranged from 92.0% to 94.0%. The Bio-Bi-LSTM-CRF model's overall accuracy was between 8.0% and 13.0% points higher than the Bi-LSTM-CRF method in entity identification. The Bio-Bi-LSTM-CRF model achieved a higher accuracy for all outcomes for all four facilities.

CONCLUSIONS

Our experiments show that the bidirectional encoder representations by integrating dictionary function vector from Bio-Bi-LSTM-CRF and strategies character sequence embedding approach is an effective way to identify colonoscopy features from EHR-extracted clinical notes. The Bio-Bi-LSTM-CRF model creates new opportunities to identify patients at risk for colon cancer and study their health outcomes.

Authors: Tsai Chan-Hen , Chen Pei-Chen , Liu Ding-Shan , Kuo Ying-Ying , Hsieh Tsung-Ting , Chiang Dai-Lun , Lai Feipei , Wu Chia-Tung
Published: August 2021

BACKGROUND

A panic attack (PA) is an intense form of anxiety accompanied by multiple somatic presentations, leading to frequent emergency department visits and impairing the quality of life. A prediction model for PAs could help clinicians and patients monitor, control, and carry out early intervention for recurrent PAs, enabling more personalized treatment for panic disorder (PD).

OBJECTIVE

This study aims to provide a 7-day PA prediction model and determine the relationship between a future PA and various features, including physiological factors, anxiety and depressive factors, and the air quality index (AQI).

METHODS

We enrolled 59 participants with PD (Diagnostic and Statistical Manual of Mental Disorders, 5th edition, and the Mini International Neuropsychiatric Interview). Participants used smartwatches (Garmin Vívosmart 4) and mobile apps to collect their sleep, heart rate (HR), activity level, anxiety, and depression scores (Beck Depression Inventory [BDI], Beck Anxiety Inventory [BAI], State-Trait Anxiety Inventory state anxiety [STAI-S], State-Trait Anxiety Inventory trait anxiety [STAI-T], and Panic Disorder Severity Scale Self-Report) in their real life for a duration of 1 year. We also included AQIs from open data. To analyze these data, our team used 6 machine learning methods: random forests, decision trees, linear discriminant analysis, adaptive boosting, extreme gradient boosting, and regularized greedy forests.

RESULTS

For 7-day PA predictions, the random forest produced the best prediction rate. Overall, the accuracy of the test set was 67.4%-81.3% for different machine learning algorithms. The most critical variables in the model were questionnaire and physiological features, such as the BAI, BDI, STAI, MINI, average HR, resting HR, and deep sleep duration.

CONCLUSIONS

It is possible to predict PAs using a combination of data from questionnaires and physiological and environmental data.

Published: August 2021

A vinhaça é um efluente gerado no processo de produção do etanol a partir da cana-de-açúcar, e devido ao teor de matéria orgânica e nutrientes presentes na vinhaça, esta tem sido utilizada na fertirrigação dos solos, porém também pode apresentar alto potencial poluidor quando utilizada inadequadamente. Este trabalho teve como objetivo avaliar as alterações das características químicas e microbiológicas do solo fertirrigado com vinhaça em diferentes sistemas de cultivos. Para isto foram coletas amostras de solo em áreas de cana-de-açúcar e pastagem que possuem um histórico de fertirrigação com vinhaça. Essas coletas foram realizadas em dois tempos distintos, 15 dias e 2 anos após a última aplicação de vinhaça. Como controle foi utilizado amostras de solos cultivados com pastagem e cana-de-açúcar, que nunca receberam aplicações de vinhaça. As características químicas analisadas foram: pH, Al, CO, P, N mineral, K, Ca, Mg, Cu e Zn. As características microbiológicas avaliadas foram: RBS (Respiração Basal do Solo), BMS-C (Carbono da Biomassa Microbiana), mineralização do N, qCO2 (quociente metabólico) e qMic (quociente microbiano). A aplicação de vinhaça no solo influenciou nas características químicas e microbiológicas do solo, com efeitos diferentes para cada cultura e ao longo do tempo subsequente a aplicação.

Abstract: In this communication, we report identification of lung cancer with the help of a new image processing technique. To start with, we compare the results obtained from our proposed method with those obtained from the original Sobel edge detection method. The comparison is done by creating a confusion matrix and considering various parameters such as True Positive, True Negative, False Positive, False Negative, Accuracy, Misclassification Rate, Precision, Recall, Specificity, F Score, Matthews Correlation Coefficient (MCC), F Measurement (FM), Z score, T Score, and P Score. Our proposed method gives better total accuracy than the normal Sobel edge detector. Keywords: Neural network, statistical learning, edge filters, deep learning, image processing

Abstract: Welcome to steady die casting solutions. We are at steady die casting solutions keep on continue to give die casting solutions. In this paper we will discuss how we can predict flash location in die and how we can correct before die making or after die making. We also discuss how we can calculate individual tie bar load when we load a die, tie bar load will change on each die changeover because of it’s center of gravity. We discuss how casting shot centroid will effect tie bar load which directly responsible for flash. All this things we try to explain with an example, I hope it will be help full. Thank you very much, “keep learning till death”. Keywords: Flash, tie bar, machine tonnage, machine center, die, hpdc, casting defect and clamping force

This article is the result of research on the heart article in the 3 Constitutional Court Decisions which canceled the entire contents of the law, namely the Constitutional Court Decision Number 001-021-022/PUU-I/2003 which canceled Law Number 20 of 2002 concerning Electricity, Constitutional Court Decision 006/PUU-IV/2006 which canceled Law 27 of 2004 concerning the Truth and Reconciliation Commission, Constitutional Court Decisions 11-14-21-126 and 136/PUU-VII/2009 which canceled the Law Number 9 of 2009 concerning Legal Education Entities, and the Constitutional Court Decision 85/PUU-XI/2013 which canceled Law Number 7 of 2004 concerning Water Resources. The term 'heart article' is the term coined by the Constitutional Court and used as the main reason for canceling the entire contents of the law. Unfortunately, in these decisions, the Constitutional Court did not elaborate further on the concept and characteristics of an article categorized as the heart article. Departing from this issue, this research aims to find out what are the concepts and characteristics of the "heart article" of a law that was completely canceled by the Constitutional Court? To help answer this question, this research employed a normative method intended to trace all legal materials, both of the Constitutional Court decisions, statutory regulations, to the literature supporting the research. The importance of this research is to give meaning to the concept of the heart article, which, in the development of legal science, is still rarely discussed. Moreover, it can serve as a reference for petitioners to conduct the judicial review and to identify whether the article being tested is the heart article.

Combretum micranthum (kinkeliba) is one of the most used medicinal plants in Senegal. However, its commercialization is poorly studied. The objective of this study is to analyze the commercialization of Combretum micranthum in Senegal. The study was carried out in two main regions of kinkeliba marketing in Senegal: Dakar, where kinkeliba is marketed; and Thies, where kinkeliba is produced and marketed.

Structured and unstructured surveys were administered to different categories of stakeholders: herbalists / traditional practitioners, collectors/ suppliers, retailers and consumers. Production sites that supply Dakar include the following: Diass, Sindia, Kiniabour, Pout, Thies Lalane.

The main sales points in Dakar are the Thiaroye and Grand Yoff markets. The kinkeliba marketing chain has short channels and women are the main stakeholders. Procurement is done by harvesting in the natural environment and by purchase for herbalists / traditional practitioners. The benefits and added value derived from the marketing of kinkeliba are positive and are increasingly evolving from producers to retailers. The kinkeliba chain, with its constraints and especially its strengths, requires better structuring and to be better known.

Nanotechnology: A novel approach for treatment of skin disorder
Authors: Tamanna , , Singh Harmeet
Published: August 2021

Skin, the integument system; pertaining to our body which consists of mainly three layers (i) Epidermis (ii) Dermis (iii) Subcutaneous Tissue. It acts as a protective barrier against many diseases and infections. Skin disorders vary greatly in symptoms and severity. Some may be attributed to situational causes while others may be genetic like atopic dermatitis, melanoma, acne vulgaris, wound healing and psoriasis. Conventional therapies are used to analyze various topical disorders suffers from many limitations i.e. less efficacy, poor patient compliance, and poor bioavailability. Therefore, novel approaches should be investigated for the development of better treatment of the disease. Novel carriers such as Liposome, Niosomes, Ethosomes, Silver nanoparticles, Solid lipid nanoparticles are utilized through almost all the routes of administration to treat dermatological disorders. These Nano systems are used to provide targeted drug delivery and a site-specific delivery of dosage form at a particular receptor site and thus enhance the uptake of poorly soluble drugs and overcome the issues related to poor bioavailability. The root cause for the development of such carriers lies on making the existing drugs more effective and safe for the patients.

Trade treaties of Russian and British empires with Yattishar: historical and legal study
Authors: Pochekaev Roman Yu.
Published: August 2021

The relations of the Russia and Britain with the self-declared state of Yettishar was a striking example of different approaches of two empires to the states and peoples of the Central Asian regions within so called Great Game, i.e. Russo-English rivalry in the 19th c. The trade treaties of Yattishar with the Russian Empire of 1872 and with the British Empire in 1874 became a legal reflection of these approaches and are of great interest within the context of the historical experience of the legal status of unrecognized states and positions of the rival world powers towards such states. The purpose of the article is a historical-legal analysis of above-mentioned treaties and comparative-legal analysis of them with the similar treaties signed by Russia and England with other Central Asian states during the same period. Author attempts to clarify if treaties of 1872 and 1874 confirmed recognition by both empires of Yettishar as a subject of international relations and how these legal documents reflected confrontation of Russia and England in the region. The study is mainly based on the formal-legal, historical legal and comparative-legal methods. Also author used the methods of legal anthropology and general history. The results of the research to a certain extant correlate with modern approaches in the policy of Russian and western powers in Central Asia in terms of political situation in the region as well as political, legal and cultural traditions of Central Asian states and peoples.
