Authors: EFEOĞLU Ebru , TUNA Gürkan
Published: November 2021

Detection of hazardous liquids used in explosive production is important in terms of public safety and health. Because many threats can be prevented by detecting these liquids at security controls points. As existing methods have some disadvantages in terms of accuracy, practicality or reliability, there is a demand for new methods for hazardous liquid detection. In this paper, a circular patch antenna for hazardous liquid detection was designed and by connecting to a vector network analyzer a group of measurements was made. Then, this dataset was used by hierarchical clustering algorithms employed in this study to detect hazardous liquids. The results show that high classification accuracy can be achieved when Ward linkage method is preferred.

“The Fatherland is not in Geography...”: on the Issue of the Evolution of Traditional Spiritual and Political Values of Russian Civilization*
Authors: Perevezentsev Sergey V. , Puchnina Olga E. , Strakhov Alexander B. , Shakirova Adelina A.
Published: November 2021

The article is devoted to the study of Russian traditional basic values. On the basis of the traditionalist-conservative approach, the authors investigate the origin and substantial evolution of the concept of “fatherland” in the public consciousness of the Russian people. The study of a large number of various sources on Russian intellectual history allows to conclude that the concept of “fatherland” began to appear in chronicles, literary and spiritual-political monuments relatively early – already from the 10th century, but then it had the meaning of “hereditary property”, “ancestral possession”. Meanwhile, already in the 12th–17th centuries, the use of the concept «fatherland» in the meaning of “homeland”, “native land” were found sometimes, and since the 18th century the notion “Fatherland” was finally entrenched with the value content of patriotic love and service for the benefit of one's native country. In the 19th century in Russia, the notion of “love for the Fatherland” received a variety of interpretations, enriched with new meanings and contexts, but retained its significance as one of the most important social values and civic virtues. The authors of the article conclude that despite the cardinal transformations of the social, economic and political structure of Russia in the beginning of the 20th century, the concept of “Fatherland” as a value has retained its basic significance for Russian civilization, since it is a fundamental spiritual and political ideal and is directly related to the formation of political identity.
The Notion of Power and Liberalism Evolution
Authors: Matveychev Oleg A.
Published: November 2021

The author of the article makes the attempt to explain the evolution of liberalism and even broader, of human history not through the evolution of the notion of freedom, that became the philosophic mainstream already at the time of Hegel and was convenient for liberalism itself, but on the basis of the notion of power analysis that is interpreted by the liberals as opposite to freedom. Proceeding from the linguistic and political history data, the author demonstrates the multi-components character of the notion of power that is interpreted as: 1) some intriguing and “charming” authority ensuring harmony and order; 2) the source of legal violence; 3) the promise of advantages that leads to voluntary assuming certain responsibilities; 4) dependence on the source of want satisfaction; 5) passion, irrational dependence. The present notion of power structure is coherent to the Varna system specific for Indo-European nations; each Varna has its own, specific only for it, understanding of power. In various epochs and in various societies we find a specific governing notion of power. So, in Russia since ancient times the worldview of Kshatriyas prevailed and it still determines to a large extent its civilizational specifics. The classic western liberalism was characterized by the Vaishyas ideology dominance, i.e. the bourgeois class; on the contrary modern liberalism, libertarianism share the world view of the “classless society” of the Dalits (“gone astray”), whose dominance deprives the world of controllability and destructs all vertical hierarchy. The way out of the universal crisis is possible only on the basis of new historical grounds that will become, according to Heidegger, “the new beginning of history”.

Presence of analyst before IPO and underpricing: a Meta-analysis.
Authors: Karnatak Udayan , Malik Chirag
Published: November 2021

The effect of analyst presence on underpricing has shown a contrasting result. By synthesizing the result using meta-analysis for twelve studies with more than 20400 firms we found conclusive evidence of the relation between analyst presence and underpricing of IPOs. With the increase in analyst presence by 1% the IPO underpricing increases by 4.9%. Moreover, meta-regression between effect size and moderator variables found the significant and positive role of the reputed underwriter to increase underpricing when the IPO has coverage of analysts. Our results are striking for the US market IPOs in which reputed underwriters as moderator affect underpricing significantly and positively which shows reputation increase information asymmetry. Whereas in emerging markets IPOs reputed underwriters increase market efficiency and information symmetry.

O que pode a escola pública diante das desigualdades?
Authors: Almeida Maria Isabel de , Salces Claudia Dourado de , Fernandes Tiago Rufino
Published: November 2021

Este artigo objetiva problematizar a função social da escola pública no enfrentamento da desigualdade, compreendida como uma categoria estrutural para o entendimento da sociedade brasileira e possuidora de expressões em diferentes campos, razão pela qual se caracteriza como sendo de natureza multideterminada. Sua existência e permanência foram abordadas em uma de suas formas fundamentais – a educacional –, elencando-se as desigualdades educativas no escopo da desigualdade como marcador estrutural. Realizou-se um breve percurso histórico do papel da escola pública, evidenciando como os modos de escolarização possuem uma relação direta e explícita com políticas educacionais forjadas nacional e internacionalmente, além de destacar os desafios que permitem formular um diagnóstico do quadro histórico atual em matéria educativa. Evidenciou-se que a desigualdade escolar, atrelada a um projeto político, além de ser o resultado da ineficácia das políticas públicas, é, também, o produto dessas. Em face dessas contingências, foram aventados alguns desdobramentos responsivos da escola em face, sobretudo, do currículo e da formação de professores. Em termos metodológicos, trata-se de uma pesquisa bibliográfica de caráter conceitual, que problematiza a desigualdade como conceito multidimensional. A referência teórica, embasada em uma perspectiva crítico-transformadora, com o auxílio de uma sociologia crítica, buscou uma aproximação com orientações que vislumbram a superação das desigualdades escolares.
Assessing the burden of dengue among household members in Alaminos, Laguna, the Philippines: a prospective cohort study
Authors: Capeding Maria Rosario , de Boer Melanie , Damaso Silvia , Guignard Adrienne
Published: November 2021

Background

The incidence of dengue is increasing rapidly and is a challenging health issue in the Philippines. Epidemiological data are largely based on a passive-surveillance reporting system, which leads to substantial under-reporting of cases.

Objectives

To estimate dengue infection and disease incidence prospectively at the community level in an endemic area of the Philippines using an active surveillance strategy.

Methods

We implemented active surveillance in the highly endemic community of Alaminos, Laguna. The study consisted of a 1-year follow-up with 2 visits scheduled at the start and end of the study, as well as regular active surveillance in between and unscheduled visits for suspected cases. Blood samples were collected and analyzed to detect dengue during the first scheduled visit and all unscheduled visits, and clinical examination was performed at all visits (registered at clinicaltrials.gov NCT02766088).

Results

We enrolled 500 participants, aged from 6 months to 50 years; 76.2% were found positive for immunoglobulin G (95% confidence interval [CI], 71.9–80.0), with 92.0% among those aged 9–17 years. Active (weekly) surveillance identified 4 virologically confirmed cases of dengue (incidence proportion 0.8; 95% CI 0.3–2.1); all in participants aged ≤14 years.

Conclusions

Routine surveillance programs such as sentinel sites are needed to characterize the entire clinical spectrum of symptomatic dengue, disease incidence, and transmission in the community.
Classification of Open-End Investment Funds Using Artificial Neural Networks. The Case of Polish Equity Funds
Authors: Perez Katarzyna , Szczyt Małgorzata
Published: November 2021

In this study we utilise artificial neural networks to classify equity investment funds according to two fundamental risk measures—standard deviation and beta ratio—and to investigate the fund characteristics essential to this classification. Based on a sample of 4,645 monthly observations on 37 equity funds from the largest fund families registered in Poland from December 1995 to March 2018, we allocated funds to one of the classes generated using Multilayer Perceptron (MLP) and Radial Basis Function (RBF). The results of the study confirm the legitimacy of using machine learning as a tool for classifying equity investment funds, though standard deviation turned out to be a better classifier than the beta ratio. In addition to the level of investment risk, the fund classification can be supported by the fund distribution channel, the fund name, age, and size, as well as the current economic situation. We find historical returns (apart from the last-month return) and the net cash flows of the fund to be insignificant for the fund classification.
Feature and Tendency of Technology Transfer in Z-Park Patent Cooperation Network: From the Perspective of Global Optimal Path
Authors: Guan Jun , Xu Jingying , Han Yu , Wang Dawei , Xing Lizhi
Published: November 2021

Purpose

This study aims to provide a new framework for analyzing the path of technology diffusion in the innovation network at the regional level and industrial level respectively, which is conducive to the integration of innovation resources, the coordinated development of innovative subjects, and the improvement of innovation abilities.

Design/methodology/approach

Based on the Z-Park patent cooperation data, we establish Inter-Enterprise Technology Transfer Network model and apply the concept of Pivotability to describe the key links of technology diffusion and quantify the importance of innovative partnerships. By measuring the topologically structural characteristics in the levels of branch park and the technosphere, this paper demonstrates how technology spreads and promotes overall innovation activities within the innovation network.

Findings

The results indicate that: (1) Patent cooperation network of the Z-Park displays heterogeneity and the connections between the innovative subjects distribute extremely uneven. (2) Haidian park owns the highest pivotability in the IETTN model, yet the related inter-enterprise patent cooperation is mainly concentrated in its internal, failing to facilitate the technology diffusion across multiple branch parks. (3) Such fields as “electronics and information” and “advanced manufacturing” are prominent in the cross-technosphere cooperation, while fields such as “new energy” and “environmental protection technology” can better promote industrial integration.

Research limitations

Only the part of the joint patent application is taken into account while establishing the patent cooperation network. The other factors that influence the mechanism of technology diffusion in the innovation network need to be further studied, such as financial capital, market competition, and personnel mobility, etc.

Practical implications

The findings of this paper will provide useful information and suggestions for the administration and policy-making of high-tech parks.

Originality/value

The value of this paper is to build a bridge between the massive amount of patent data and the nature of technology diffusion, and to develop a set of tools to analyze the nonlinear relations between innovative subjects.

Eleven dogs with meningiomas were treated surgically for 5 years. All tumors except one were resected radically (Simpson 2). Localization of tumors mirrored that of human meningiomas.

Results:

Two dogs died in direct relation to surgery. One died 14 months after surgery due to tumor regrowth. Three dogs died of unrelated causes 10–36 months after tumor resection and five dogs are alive and tumor-free 2–42 months after surgery.

Conclusion:

Radical surgery in dogs is as effective as in humans. Thus, we propose that it should be implemented as first-line treatment. The article is meant to please all those overly curious neurosurgeons in the world.

Background:

Castleman’s disease (CD) is a rare lymphoproliferative disease of unknown origin which rarely affects the spine. Here, we present CD involving a lytic, destructive C3 lesion with extension into the spinal canal contributing to upper cervical cord compression. Notably, the lesion mimicked other primary bone lesions, metastatic tumors, and/or lymphoma.

Case Description:

A 52-year-old male presented with progressive quadriparesis (i.e. weakness, instability of gait) and loss of dexterity in both hands over 2 weeks. The MRI, X-ray, and CT scans revealed a destructive lytic lesion involving the C3 vertebral body (i.e. including both anterior and posterior elements). The patient underwent a C3 total and C4 partial laminectomy followed by a C2-C4/5 instrumented fusion (i.e. included C2 pedicle screws/laminar screws, and C4/C5 lateral mass fixation). Histopathology showed a lymphoproliferative disorder with follicles of different sizes, central abnormal germinal structures, and a Mantle zone (i.e. expanded germinal centre with concentric layering with an “onionskin” appearance). These findings were all consistent with the diagnosis of CD (i.e. hyaline-vascular type).

Conclusion:

CD, a rare lymphoproliferative disease of unknown origin rarely affects the spine. Here, we presented a 52-year-old male with a C3 lytic lesion resulting in C3/4 cord compression that favorably responded to a C3/4 laminectomy with posterior instrumented fusion.

Разбирается проблематика изучения городищ раннеславянского круга культур третьей четверти I тыс. н. э. – псковских длинных курганов, тушемлинско-банцеровской и колочинской. Среди проблем – культурная принадлежность отдельных памятников и целых групп, датировка, интерпретация городищ. Из числа упоминаемых в литературе 258 городищ указанных культур на карту нанесено 64 пункта, керамика и другие находки из которых известны и могут быть атрибутированы.

The paper explores the issues pertaining to the studies of hillforts attributed to the cultures of the early Slavic circle and dated to the third quarter of the first millennium, i. e. Pskov long kurgans, the Tushemlya-Bantserovshina culture, and the Kolochin culture. One of the issues is cultural attribution of specific sites and entire groups of sites, dating and interpretation of hillforts. Out of 258 fortified sites of these cultures mentioned in the literature, 64 locations from where ceramics and other finds had been retrieved and that could be attributed to certain cultures are shown on the map.

Виноградная выжимка – вторичный продукт переработки винограда – богата биологически ценными веществами. Представляет интерес выбор фракций порошка из виноградной выжимки, наиболее перспективных для обогащения кондитерских изделий. Исследованы физико-химические показатели 7 образцов различных фракций порошка из выжимки винограда сорта Мерло. Выжимки были высушены с использованием инфракрасной сушилки при температуре 45–50°C до влажности 8–9%, измельчены по инновационной технологии на мельнице молоткового типа до размера частиц 0,3–1,0 мм и разделены на фракции в классификаторе инерционного типа ГИЛ 21. Массовую долю моно- и дисахаридов (общих сахаров) в образцах виноградного порошка определяли по методу Бертрана, содержание общих полифенолов – колориметрическим методом. Установлено, что наибольшее количество общих сахаров (4,6%) содержится в образце 5 – готовом продукте, отобранном со второго уровня классификатора, где клетчатка, протопектин, гемицеллюлоза и другие вещества разрушаются до моносоединений. По содержанию полифенолов из всех образцов наибольшим количеством (6622,8 мг/100 г) выделяется образец 3, находившийся в классификаторе минимальное количество времени. Эти фракции обеспечивают максимальную ценность выжимки при использовании для производства кондитерских изделий. При конструировании рецептур пищевых добавок в зависимости от цели их использования необходимо варьировать сочетание различных фракций виноградного порошка.

Grape pomace – a secondary product of grape processing – is rich in biologically valuable substances. The choice of fractions of grape pomace powder, the most promising for enriching confectionery products, is of interest. Physico-chemical parameters of 7 samples of various fractions of powder from the pomace of Merlot grapes investigated. The pomace was dried using an infrared dryer at a temperature of 45–50°C to a humidity of 8–9%, crushed using an innovative technology in a hammer-type mill to a particle size of 0,3–1,0 mm and divided into fractions in an inertia-type classifier. The mass fraction of mono- and disaccharides (total sugars) in the samples of grape powder was determined by the Bertrand method, the content of total polyphenols was determined by the colorimetric method. It was found that the largest amount of total sugars (4,6%) is contained in sample 5 – a finished product selected from the second level of the classifier, where fiber, protopectin, hemicylose, etc. are destroyed to monocompounds. According to the content of polyphenols, the largest amount of all samples (6622,8 mg/100 g) is allocated to sample 3, which was in the classifier for the minimum amount of time. These fractions provide the maximum value of the squeeze when used for the production of confectionery products. The combination of different fractions of grape powder must be varied when designing recipes for food additives, depending on the purpose of their use.

Рост числа больных с алиментарно-зависимыми заболеваниями во многих странах делает необходимым расширение ассортимента продуктов для диетического питания. Исследована возможность применения полисахаридов микробного и растительного происхождения в качестве структурообразователей в рецептуре творожного суфле для безглютенового питания. Предложена замена глютенсодержащего сырья – пшеничной муки на полисахариды (ПС) ксантан и гуаран. Объектом исследования были образцы творожного суфле с внесенным ксантаном или гуараном в количестве 0,3; 0,5; 0,7 и 1,0% от массы сырья взамен пшеничной муки. Контролем служил образец суфле из творога, приготовленного по стандартной рецептуре, без замены пшеничной муки ПС. Установлено, что после выпечки консистенция изделий с ксантаном не соответствовала требованиям, предъявляемым к суфле: оно было плотным и не обладало ярко выраженной характерной пористостью. Наивысшую органолептическую оценку получил образец суфле с содержанием 0,3% гуарана со структурой и вкусом, характерными для контрольного образца. Исследованные физико-химические показатели и пищевая и энергетическая ценность разработанного творожного суфле для безглютенового питания сопоставимы с аналогичными показателями контрольного образца. Рассчитано, что при годовом объеме выработки разработанной продукции 35,3 т срок окупаемости составит 0,33 года при рентабельности 50%.

The increase in the number of patients with alimentary-dependent diseases in many countries makes it necessary to expand the range of products for dietary nutrition. The possibility of using polysaccharides of microbial and plant origin as structure-forming agents in the formulation curd souffle for gluten-free nutrition has been investigated. Replacement of gluten-containing raw materials – wheat flour with polysaccharides (PS) xanthan and guaran is proposed. The object of the study was samples of cottage cheese souffle with xanthan or guaran added in the amount of 0,3; 0,5; 0,7 and 1,0% of the mass of raw materials instead of wheat flour. The control was a sample of a souffle made of curd prepared according to a standard formulation, without replacing wheat flour with PS. It was found that after baking, the consistency of products with xanthan did not meet the requirements for the souffle: it was dense and did not have a pronounced characteristic porosity. The highest organoleptic rating was given to a souffle sample containing 0,3% guaran, which had the structure and taste characteristic of the control sample. The studied physical and chemical parameters and the nutritional and energy value of the developed curd souffle for gluten-free nutrition are comparable with similar indicators of the control sample. It is calculated that with an annual output of 3,3 tons of developed products, the payback period will be 0,33 years with a profitability of 50%.
