RESUMO:O presente artigo examina a proposta do Estado Plurinacional, enquanto projeto  político alternativo ao Estado Nacional. Primeiramente, contextualizamos o assunto, com uma breve exposição do novo constitucionalismo latino-americano, onde se desenvolveu e se levou a cabo a proposta do Estado Plurinacional. Em seguida, relacionamos as características do Estado Nacional, enquanto construto da Modernidade que busca uniformizar vidas e visões de mundo, na persecução cega da conformação da realidade a condições ótimas para o desenvolvimento de um sistema econômico, o capitalismo. O Estado Nacional nega a pluralidade de corporalidades, espacialidades e territorialidades, gerando exclusão, marginalização e extermínio. Prosseguindo, apresentamos a proposta do Estado Plurinacional, através de uma revisão da Teoria Geral do Estado e, com achegas da Sociologia, traçaremos suas características. O Estado Plurinacional deve reconhecer a diversidade cultural que abriga e acolher as lutas por reconhecimento advindas dessa mesma diversidade. Deve, também, reconhecer que não mais monopoliza a produção do direito e a regulação da vida social. Finalmente, faremos um apanhado dos pressupostos do Estado Plurinacional, sistematizando-os. ABSTRACT:This paper examines the proposal of the Plurinational State, as an alternative political project to government. First, this article contextualize the issue, with a brief exhibition of the new Latin American constitutionalism, where it has been developed and carried out the proposal of the Plurinational State. Then, this article relate the characteristics of the National-State, showing it as a herald of modernity, which standardize lives and world-views, in the blind pursuit of shaping reality in optimal conditions for the development of an economic system, capitalism. The National State denies the plurality of corporeality, spatiality and territoriality, generating exclusion, marginalization an d death. Proceeding to the proposal of the Plurinational State, through a review of the General Theory of State, and with subsides in Sociology, this article will trace its main features. The Plurinational State must recognize the cultural diversity that houses and embrace the struggles for recognition which arise out of that diversity. The Plurinational State should also recognize that the State no longer monopolizes the production of law and the regulation of social life. Finally, it will make an overview of the prerequisites of the Plurinational State, systematizing them.

Resumo:  O objetivo da presente abordagem é afirmar o espaço público como indispensável para a expressão e interação dos indivíduos na formação da cidadania e, assim, compor a democracia no contexto contemporâneo. A garantia de direitos e a sua efetivação no cotidiano da convivência humana são as referências mais elementares e condição para a sua legitimidade. Tradicionalmente, as formas de participação e decisão dependiam exclusivamente de eleições que garantiam a alternância do poder. Esse é um modelo limitado e insuficiente, considerando a complexidade das sociedades hodiernas que pressupõe a existência de uma nova dinâmica. Os conflitos de representação e decisão impulsionam a proposição de novos paradigmas para a interação e efetivação de direitos. Os movimentos sociais, as formas de interação e a expressão da pluralidade existente na sociedade, demandam um modelo de participação intersubjetiva, indicando a cidadania como espaço de interação e vociferação de direitos, especificamente os direitos das culturas, a superação das desigualdades, os novos instrumentos de decisão e as condições efetivas de integração dos povos, ampliando as condições de justiça. Afirmar valores e princípios como a tolerância, a legalidade, a dignidade humana, a sustentabilidade e o compromisso com as futuras gerações, representa a capacidade de evolução da democracia e a necessidade de novos referenciais.Abstract: he objective of this approach is to affirm the public space as essential for the expression and interaction of individuals in the formation of citizenship and thus compose democracy in the contemporary context. The guarantee of rights and its effectiveness in everyday human coexistence are the most basic references and condition for its legitimacy. Traditionally, the forms of participation and decision relied solely of elections that guaranteed the alternation of power. This is a limited and insufficient model considering the complexity of today's society that presupposes the existence of a new dynamic. Conflicts of representation and decision boost to propose new paradigms for interaction and enforcing rights. Social movements, forms of interaction and expression of the existing plurality in society, require a model of inter-subjective participation, indicating citizenship as a space for interaction and vociferation rights, specifically the rights of cultures, overcoming inequalities, the new instruments decision and the actual conditions of integration of peoples, expanding the conditions of justice. Affirming values and principles such as tolerance, legality, human dignity, sustainability and commitment to future generations, is the evolution of the capacity of democracy and the need for new standards.

Resumo: O presente artigo analisa a relevância da atividade cafeeira no Brasil e sua histórica relação com a degradação do meio ambiente. Diante da função socioambiental da propriedade rural, estabelecida pela Constituição Federal de 1988, não se pode admitir, hodiernamente, que o cultivo e a plantação de café sejam prejudiciais ao meio ambiente ecologicamente equilibrado. Constata-se que a as questões ambientais foram e continuam sendo inerentes à cafeicultura e procura-se aferir se, efetivamente, poder-se-ia imputar responsabilidade civil a eventuais degradadores. Buscou-se compreender o problema por meio de raciocínio dedutivo, com vertente metodológica jurídico-teórica, alicerçando-se na análise de doutrinas e artigos relacionados ao tema proposto.Abstract: This article analyzes the relevance of the coffee industry in Brazil and its historical relationship with the degradation of the environment. Given the socio-environmental function of rural property, established by the 1988 Federal Constitution, it is unacceptable, in our times, the cultivation and the coffee plantation be harmful to an ecologically balanced environment. It notes that the environmental issues have been and are involved in coffee production and seeks to assess whether, in fact, power would impute liability to any degrading We tried to understand the problem through the deductive method, basing on the analysis of doctrines and articles related to the proposed topic.

Résumé: Cet article discute la utilisation du nom peuple dans les discours politiques et dans les textes normatifs, mise en question à quel point dans l'imaginaire collectif des démocraties occidentales (au moins) et dans la construction de cet imaginaire par le droit, le fonctionnement du droit, la légitimité de l'autorité politique, et l'idée de peuple sont liés. Réfléchie sûr la question de la mise en exergue du peuple transcende maintes oppositions idéologiques, et s’accommode de toutes les justifications, même les plus inacceptables. Dit que le peuple ne signifie rien de réel. Nommer qu'il existe un peuple, et déduire que l'Etat dont la constitution nomme est l'Etat d'un peuple, c'est fondre les différences réelles dans un collectif unitaire, et c'est ainsi nier toutes différences. Il y a dans le recours au peuple une dimension holistique qui participe efficacement de ce juridisme formel.Resumo: O presente artigo discute a utilização do nome do povo nos discursos políticos e textos normativos pondo em questão a que ponto no imaginário coletivo das democracias ocidentais e na construção desse imaginário pelo direito, o funcionamento do direito, a legitimidade da autoridade política e a ideia de povo estão ligadas. Reflete sobre o fato de que a colocação em evidência do povo transcende várias oposições ideológicas e se adapta a todas as justificações, mesmo as mais inaceitáveis. Afirma que povo em realidade não diz nada. Conclui que nomear um povo e deduzir que o Estado cuja constituição nomina é o Estado de um povo, é fundir as diferenças reais num coletivo unitário e negar as diferenças. Há no recurso ao povo uma dimensão holística que participa eficazmente do juridicísmo formal.Abstract: This article discusses the use of people’s name in political speeches and normative texts, calling into question to what extent in the collective imaginary of western democracies and in the construction of this imaginary by law, the functioning of law, the legitimacy of political authority and the idea of people are all linked. It reflects on the fact that the evidence of people transcends various ideological oppositions and adapts to all justifications, even the most unnaceptable ones. It also affirms that people do not really say anything. In the end, it concludes that to name some people and to deduce that the State which the constitution nominates as the state of the people, is to merge the real differences into a unitary collective and deny the differences. In the use of the people, there is a holistic dimension that effectively participates in formal juridicism.

Resumo: Busca-se investigar acerca da existência de um novo modelo de Constituição Econômica no Novo Constitucionalismo Latino-Americano, em especial, nas recentes Constituições do Equador (2008) e da Bolívia (2009). São examinados alguns aspectos econômicos presentes nessas Constituições, em especial: o pluralismo jurídico-econômico, a democracia econômica, a soberania econômica, a distribuição socioambiental dos resultados econômicos, o desenvolvimento do mercado interno, a natureza como recurso econômico e a vedação ao monopólio e oligopólio. Num exame crítico, arremata-se que, embora essas cartas constitucionais examinadas permaneçam afirmando um modelo desenvolvimentista, de fato, elas apontam para uma nova proposta de desenvolvimento, baseada no pluralismo econômico, mediante a imposição maiores restrições de cunho socioambiental para a livre iniciativa.Abstract: It intends to investigate on the existence of a new model of Economic Constitution within the New Latin American Constitutionalism, especially in the recent Constitutions of Ecuador (2008) and Bolivia (2009). Some economic aspects in these constitutions are examined, particularly: the legal-economic pluralism, economic democracy, economic sovereignty, environmental distribution of economic results, the development of the internal market, the nature as an economic resource and prohibition of monopoly and oligopoly. In a critical analysis, it concludes that, although these constitutions remain stating a developmental model, in fact, they point to a new development proposal based on economic pluralism by imposing greater socio-environmental restrictions for free enterprise.

Decolonization and Denazification: Student Politics, Cultural Revolution, and the Affective Labor of Remembering
Authors: Schuhmann Antje
Published: July 2017

In 2015 students in South Africa mobilized to decolonize universities and to struggle for free higher education. This article discusses these developments in the context of contemporary theories of remembrance, repression and denial and current debates around decolonization and “talking race” in post-apartheid South Africa. The current South African student movement(s) challenge apartheid legacies and white colonial culture, contending that campuses are still dominated by racist symbolic and economic orders. They argue, “As we learn we need to unlearn and develop new epistemologies.” This article analyses this process as it unfolds and looks at the unfolding intergenerational tensions and discusses how a lack of affirmative labor of remembrance on the side of the white South African population complicates notions of decolonization in relation to a gendered black nationalism. A point of conceptual reference is the 1968 student protest movement in West Germany, which forcefully broke the silence surrounding fascist continuities within the newly democratized institutions (and society) that was “unable to mourn” and remember.
Race Trouble and the Impossibility of Non-Racialism
Authors: Durrheim Kevin
Published: July 2017

What is the compulsion that keeps race and racism in play? This article considers how the struggle for non-racialism, color blindness, and post-racialism can work to keep racism alive. Ironically, ideas about racism are often kept current by attempts to avoid or criticize racism. In previous work, the author has defined race trouble as the “implicit or explicit use of constructions of ‘racism’ for accountable conduct.” We use ideas about racism to conduct ourselves accountably in racialized worlds. Ideas about what constitutes racism help us to live as decent human beings, criticizing racism and avoiding acting like racists. This article will provide an analysis of a high-profile and widely condemned archetypal incident of racism in post-apartheid South Africa, namely, the video made by students at the Reitz Residence at the University of the Free State in 2007, which depicted scenes of abuse against black cleaners by white male students. It will use these materials to show how racism can be perpetuated by antiracist discourse, thus making the argument reflected in the article title.
¿El fin de una tipología? Expectativas de las estructuras laminares en el panorama actual.
Authors: Humanes Cisnal Alberto
Published: July 2017

Las estructuras laminares, como las realizadas por Eduardo Torroja y Félix Candela, han supuesto un salto cualitativo en la concepción espacial de la arquitectura del siglo XX. El que hoy esta tipología se encuentre en desuso es un hecho interesante, ajeno a las consideraciones meramente resistentes. La aparición y desaparición de sistemas estructurales, siempre va ligado a cambios históricos, que nos permiten entender los razonamientos que rigen la actividad humana, enfrentando el futuro con el peso de la consciencia técnica e histórica. Desde la tesis de la que forma parte este estudio, se busca comprender estos factores y la incidencia de las capacidades materiales, técnicas y de cálculo, en la concepción proyectual y en especial en las arquitecturas de grandes luces, como ámbito extremo de referencia.

Está información da las bases para entender cómo funciona la gestión de color a nivel nacional y además permite identificar posibles estrategias para implementar control y comunicación del color en la industria de Retail textil nacional.
The Olympic Games Barcelona '92, an Early and Very Successful Experience in Design Management. A Talk With Jaume Masferrer
Authors: Calvera Anna
Published: July 2017

Ya pasaron 25 años desde la celebración de los juegos olímpicos en Barcelona. Por lo que concierne al diseño, se tomaron decisiones que llamaron la atención internacionalmente por la calidad de las propuestas y los riesgos adoptados. A parte de los muchos edificios singulares y la reforma urbanística de la ciudad, se diseñó hasta el más mínimo detalle, desde las señales hasta los souvenirs y los atrezos de las pruebas deportivas. Pero lo que es más importante, tuvo lugar en una época en la que recién comenzaba a hablarse de la gestión del diseño como actividad complementaria y paralela al diseño. El objeto de este artículo es mostrar cómo se llevó la gestión de esta política y los éxitos alcanzados explicado por Masferrer, uno de las personas a cargo de esta gestión. Se trata por lo tanto de un ejercicio de recolección de datos a la manera de la Historia Oral aplicada al Design Management como nueva especialidad del diseño.
Nature and Dynamics of Industry-Based Workplace Learning for South African TVET Lecturers
Authors: van der Bijl Andre , Taylor Vanessa
Published: July 2017

This article reports on the findings of an industry workplace experience project involving lecturers in South Africa's technical and vocational education and training (TVET) colleges, against the backdrop of new legislation and the realization that college lecturers' industry-related skills are in question. Its focus is on the nature of TVET lecturer industry-based workplace learning and the internal dynamics of its implementation in the college and employer systems. The article provides background on workplace-based learning for TVET lecturers and contrasts this form of workplace learning with forms used for students. After providing a critical analysis of methods used to theorize workplace-based learning, a model is employed to describe and analyse lecturers' experiences, with the aim of informing national and international knowledge and practice. The study supports the argument that workplace-based learning for TVET lecturers is not the same as for students. While students are exposed to workplaces to provide them with orientation and initial skills for future careers, workplace-based learning for lecturers is designed to improve knowledge development competencies. TVET lecturers undertake workplace-based learning to improve their knowledge of practice and so improve their theorization and teaching skills. The article points to the need for further research on and theorizing of industry-based workplace learning for lecturers.

Authors: Zhou Jian , Yang Yue-hua , Sun Zhi-ming , Li Ying
Published: July 2017

Objectives: Analysis of the risk factors related to ectopic pregnancy (EP) among intrauterine device (IUD) users in order to reduce the risk of EP from IUD users and to safeguard women’s health.Methods: A total of 29 EP cases were collected and 1:1 matched controls in IUD users by case-control study.Results: The data showed that pregnancies had significant association with EP, two pregnancies and three or more pregnancies were increased the risk of EP, adjusted odds ratio AOR = 14.39, 95% CI: 2.37, 87.49 and AOR = 14.87, 95% CI: 2.27, 97.38 respectively. The risk of EP in women of previous abdominal or pelvic surgery was also significantly increased (AOR = 4.43, 95% CI: 1.04, 18.92). While no significant association have been seen with age, first or second time use IUD, periods of insertion, types of IUD, and copper surface area of IUD.Conclusion: The results suggest that the number of pregnancies significantly increase the risk of EP, there is no significant association between the risk of EP and copper surface area or shape of IUD used. Therefore, a woman’s individual risk factors will lead to a rise in the risk of EP, there is a need to the suitability of her contraceptive. It is beneficial to reduce the risk of EP by the prevention of unwilling pregnancy and induced abortion.
Previously Unknown Physical Formulas which Hold in a Hydrogen Atom and are Derived without Using Quantum Mechanics
Authors: Suto Koshun
Published: July 2017

It is thought that quantum mechanics is the physical science describing the behavior of the electron in the micro world, e.g., inside a hydrogen atom. However, the author has previously derived the energy-momentum relationship which holds inside a hydrogen atom. This paper uses that relationship to investigate the relationships between physical quantities which hold in a hydrogen atom. In this paper, formulas are derived which hold in the micro world and make more accurate predictions than the classical quantum theory. This paper concludes that quantum mechanics is not the only theory enabling investigation of the micro world.
Volatility and Causality in Strategic Commodities: Characteristics, Myth and Evidence
Authors: Chang Youngho , Fang Zheng , Hamori Shigeyuki
Published: July 2017

Commodity prices have fluctuated sharply and Brent oil has been considered the most volatile commodity in price. This paper aims to reveal the true characteristics of the price volatility of six commodities, namely, Brent oil, gold, silver, wheat, corn and soybean and to verify the existence of a long-run relationship and causation among each pair of commodity prices. It finds that there has been persistent volatility in prices of all six commodities from 1986 to 2010. Contrary to the common belief, however, Brent oil appears not to be the most volatile in price. Rather the prices of precious metals and agricultural commodities have been more volatile than Brent oil for some time periods. It also finds that there has been a long-run relationship between the prices of Brent oil and soybean, of Brent oil and wheat, and a bilateral causality relationship between them, which implies that there has been a simultaneous impact on the price trajectories of these commodities.

Authors: Lingjuan Xu , Yanjun Wang , Huailei Zhu
Published: July 2017

The paper takes Jiangsu province as example in Yangtze River Delta, which is economically developed regions. According to previous research and characteristics of rural banks in Jiangsu Province, the input indexes are selected as the number of employees, the number of outlets, total deposits, business and management fees. And the output indexes include total loans, net interest income and net profit. Using DEA model to analyze the operating efficiency of the 65 rural banks in 2016, the paper compares the operating efficiency in different regions and different types of originating bank. The analysis shows that, compared with the central and northern Jiangsu, operating efficiency of rural banks in southern Jiangsu is generally high. The comprehensive technical efficiency value of sample banks that originated by the state-owned banks and joint-stock banks is significantly higher than that originated by rural commercial banks and city commercial banks. Finally, the paper puts forward some suggestions on how to improve the operating efficiency of rural banks.

Published: July 2017

Periodontitis and gingivitis, a prevalent oral diseases, have been connected to several systemic health changes. The aim of this investigation was to review the effects of menopause on periodontal tissue. Epidemiologic studies have identified a number of risk factors and risk indicators for periodontal attachment loss, including demographic, socioeconomic, behavioral, genetic, and systemic factors. Menopause has also been associated with destructive periodontal disease in older women. The homeostasis of the periodontium involves complex multifactorial relationships. Oestrogen and progesterone are responsible for physiological changes in women at specific phases of their life. Menopause is associated with significant adverse changes in the orofacial complex.

Selective Determination of Human Growth Hormone (Somatropin) in the Presence of Its Chemical Degradation Products
Authors: Rezk Mamdouh R , Mohamed Marwa F , Fathalla Faten Abdelaziz , Shehata Mostafa A
Published: July 2017

A rapid and sensitive HPLC method was developed and validated for selective determination of the human growth hormone (hGH) somatropin in the presence of its deamidated and oxidized degradation products. Reversed-phase chromatography with an acetonitrile and ammonium bicarbonate mobile phase in gradient elution mode was used. A short run time of 15 min allowed rapid and cost-effective analysis, with an average retention time of 7.4 min for native hGH, 6.2 min for its deamidated form, and 4.3 and 6 min for its oxidized variants. The method was validated for selectivity, linearity, and intra- and interday variations according to International Conference on Harmonization guidelines. The proposed method was successfully applied for rapid evaluation of the quantity of hGH during downstream processing, formulation, and storage.

Este artigo apresenta e discute os resultados da análise de viabilidade econômica da produção familiar de alimentos, inserida na feira livre e nos mercados institucionais (Programa de Aquisição de Alimentos - PAA e Programa Nacional de Fortalecimento da Agricultura Familiar - PNAE) de Alegre-ES. Foram incluídos na pesquisa quinze alimentos: abóbora, agrião, alface, almeirão, banana prata, cebolinha, chuchu, couve, inhame, jiló, mandioca, palmito, quiabo, taioba e tomate. O custo operacional de produção e comercialização, a renda líquida operacional e o índice benefício/custo operacional foram os indicadores econômicos considerados. Verificou-se que alface, banana prata, cebolinha, couve e tomate foram os alimentos que apresentaram renda líquida operacional total positiva nos três mercados enfocados, sendo que os maiores índices benefício/custo foram alcançados pela cebolinha, no PNAE, e pela couve, no PAA. No extremo oposto ficaram a abóbora e o almeirão. A inserção dos agricultores familiares no PNAE foi, na maioria das vezes, a mais vantajosa, ao contrário do PAA, visto que oito dos quinze alimentos enfocados tiveram situação de inviabilidade econômica no mesmo.
The Usefulness of Surgical Treatment in Slow-Flow Vascular Malformation Patients
Authors: Kang Gyu Bin , Bae Yong Chan , Nam Su Bong , Bae Seong Hwan , Sung Ji Yoon
Published: July 2017

Background Many difficulties exist in establishing a treatment plan for slow-flow vascular malformation (SFVM). In particular, little research has been conducted on the surgical treatment of SFVMs. Thus, we investigated what proportion of SFVM patients were candidates for surgical treatment in clinical practice and how useful surgical treatment was in those patients.

Methods This study included 109 SFVM patients who received care at the authors’ clinic from 2007 to 2015. We classified the patients as operable or non-operable, and analyzed whether the operability and the extent of the excision varied according to the subtype and location of the SFVM. Additionally, we investigated complications and self-assessed satisfaction scores.

Results Of the 109 SFVM patients, 59 (54%) were operable, while 50 (46%) were nonoperable. Total excision could be performed in 44% of the operable SFVM patients. Lymphatic malformations were frequently non-operable, while capillary malformations were relatively operable (P=0.042). Total excision of venous malformations could generally be performed, while lymphatic malformations and combined vascular malformations generally could only undergo partial excision (P=0.048). Complications occurred in 11% of the SFVM patients who underwent surgery; these were minor complications, except for 1 case. The average overall satisfaction score was 4.19 out of 5.

Conclusions Based on many years of experience, we found that approximately half (54%) of SFVM patients were able to undergo surgery, and around half (44%) of those patients were able to fully recover after a total excision.

Among the patients who underwent surgical treatment, high satisfaction was found overall and relatively few complications were reported.
Reconstruction of Large Facial Defects via Excision of Skin Cancer Using Two or More Regional Flaps
Authors: Lee Dong Min , Bae Yong Chan , Nam Su Bong , Bae Seong Hwan , Choi June Seok
Published: July 2017

Background Free-flap surgery and skin grafting can be used to reconstruct large facial defects that may result after skin cancer removal by Mohs micrographic surgery (MMS). However, these two methods may produce low postsurgical patient satisfaction with aesthetics, and free-flap surgery may produce an undue burden for the majority of skin cancer patients, who are of advanced age. Hence, the authors examined outcomes of large facial defect reconstruction using multiple flaps.

Methods Among patients undergoing MMS for skin cancer at Pusan National University Hospital between January 2013 and December 2015, we evaluated 7 patients (2 males, 5 females; average age, 73.14 years) treated for large facial defects from basal cell carcinoma. Based on operative and follow-up records, we investigated the number and type of flaps used, postsurgical complications, and patients’ post-surgical satisfaction.

Results Two and 3 types of flaps were used for 5 and 2 patients, respectively. Most frequently used were nasolabial flaps (7 times in 6 patients) and forehead flaps (once in each of 4 patients). The average follow-up period was 14 months, with no complications—including necrosis, hematoma, or wound dehiscence—observed. Post-surgical satisfaction averaged 4.4 out of a maximum of 5 points.

Conclusions Reconstruction using two or more flaps for large facial defects after skin cancer removal using MMS produced satisfactory outcomes while preventing aesthetic problems. Practitioners should consider using multiple flaps when choosing a reconstruction method for large facial defects following skin cancer removal.

Published: July 2017

Background Lipedema is a condition consisting of painful bilateral increases in subcutaneous fat and interstitial fluid in the limbs with secondary lymphedema and fibrosis during later stages. Combined decongestive therapy (CDT) is the standard of care in most countries. Since the introduction of tumescent technique, liposuction has been used as a surgical treatment option. The aim of this study was to determine the outcome of liposuction used as treatment for lipedema.

Methods Twenty-five patients who received 72 liposuction procedures for the treatment of lipedema completed a standardized questionnaire. Lipedema-associated complaints and the need for CDT were assessed for the preoperative period and during 2 separate postoperative follow-ups using a visual analog scale and a composite CDT score. The mean follow-up times for the first postoperative follow-up and the second postoperative follow-up were 16 months and 37 months, respectively.

Results Patients showed significant reductions in spontaneous pain, sensitivity to pressure, feeling of tension, bruising, cosmetic impairment, and general impairment to quality of life from the preoperative period to the first postoperative follow-up, and these results remained consistent until the second postoperative follow-up. A comparison of the preoperative period to the last postoperative follow-up, after 4 patients without full preoperative CDT were excluded from the analysis, indicated that the need for CDT was reduced significantly. An analysis of the different stages of the disease also indicated that better and more sustainable results could be achieved if patients were treated in earlier stages.

Conclusions Liposuction is effective in the treatment of lipedema and leads to an improvement in quality of life and a decrease in the need for conservative therapy.

Published: July 2017

We present the case of a patient with severe postoperative scarring from surgical treatment for gastroschisis, with the intestine located immediately under the dermal scar. Although many patients are unsatisfied with the results of scar repair treatment, few reports exist regarding severe or difficult cases involving the surgical repair of postoperative scar contracture. We achieved an excellent result via simulation involving graph paper drawings that were generated using computed tomography images as a reference, followed by dermal scar deepithelialization. The strategy described here may be useful for other cases of severe postoperative scar contracture after primary surgery for gastroschisis.

The aim of this study was to investigate the enzymatic activity of 21 bacteria isolated from refrigerated raw buffalo milk, as well as to evaluate the production of biofilm by these bacteria. Proteolytic, lipolytic and lecithinase activity, as well as the production of exopolysaccharides were evaluated at different temperatures. For all of the psychrotrophic bacteria, biofilm formation on microtiter plates was evaluated at different temperatures and in the presence of residual buffalo and bovine milk. All cultures showed a proteolytic profile while 9 cultures showed lipase activity. Lecithinase production was found in 7 of the evaluated psychrotrophic bacteria. The ability to produce exopolysaccharides was found in 12 bacteria. Of the 21 bacterial isolates, 16 were biofilm producers at 7°C. At 23°C, 20 isolates were found to be biofilm producers. At a temperature of 37°C, biofilm formation by 17 isolates was weak. In the presence of residual buffalo milk, 7 were biofilm producers, while 16 bacteria produced biofilm in residual bovine milk. The results of this study show that many isolates of psychrotrophic bacteria from raw buffalo milk have the potential to produce extracellular enzymes as well as biofilm. This deserves special attention when considering the best practices to recommend during the collection of raw milk in establishments which process milk.

Published: July 2017

In the present work the reactions of basic interaction of 5,10,15,20-tetra(4-OH-phenyl) porphyrin in acetonitrile with the perchloric acid are studied by the method of spectrophotometric titration. And the chemical kinetics of ligand with zinc acetate in the dimethylformamide was carried out. The constant of the basic dissociation of the protonated acids of 5,10,15,20-tetra(4-OH-phenyl) porphyrin and kinetic parameters of the reaction of the formation of the zinc complex was obtained. The comparative analysis of our own obtained data and literature data according to the basic and coordination properties of 5,10,15,20-tetra(4-OH-phenyl) porphyrin and 5,10,15,20-tetrapheny porphyrin in acetonitrile and dimetilforamide in the range of 298-333K was carried out, which made it possible to draw a number of the interesting conclusions, which are concerned with the stabilization of the ionic forms of ligand in the acetonitrile and the dimethylformamide and the influence of solvent on the depth of the protonation of ligand and the kinetic rate of the formation of the corresponding zinc complexes. It is shown that the stabilization of the ionic forms of ligand upon transfer from the acetonitrile to dimethylformamide reduces the depth of the protonation of ligand, which is reflected in the decrease of the values of the dissociation constants of the cation forms of porphyrin, and the kinetic rate and the corresponding power expenditures for the reaction of the formation of ZnT(4-OH-Ph)P. It is shown that reactivity of ligand in the dipolar proton-free medium can be regulated by a change in the properties of this medium, which makes it possible to forecast the processes of the synthesis of compounds with the assigned properties.Forcitation:Plotnikova A.O., Ivanova Yu.B., Mamardashvili N.Zh.

At joint grinding of components with different strength the particles of more strong material are of larger size than the particles of less strong material. The size classification of such mixture allows enriching the objective component in the end product. The scientifically grounded choice of technological conditions for effective separation of a mixture of materials of different strength is an actual problem for chemical and other industries. The computational research was done using the conception of chemical processes modeling based on the discrete analogues of the Boltzmann equation. A special program for experimentations and experimental data treatment obtained at a lab-scale fluidized bed jet mill was developed. A model to describe the grinding kinetics for each component of a mixture was developed. It allows estimating the efficiency of enrichment of the end product by the objective component. A method to solve the equations of the selective model of grinding and the computer algorithm for its realization was developed as well. The experimental data on grinding of binary mixture of components at their different content in the fluidized bed jet mill hold-up were obtained. These data were used to identify the model with respect to the parameters that characterized the grindability of each component. The model adequacy was checked using the data on joint grinding of mixtures with different content of components. These data were not used for the model identification. Comparison of calculated and experimental data showed the model adequacy and possibility of its usage to estimate the efficiency of components separation. The investigation allowed generalizing the conceptions of chemical processes modeling based on the discrete analogues of the Boltzmann equation to the case of selective grinding of a mixture of components with different strength. The computational analysis showed that the model allowed describing the process with acceptable for engineering practice accuracy, practical estimating the possibility of components enrichment and defining the optimal technological conditions for their separation.Forcitation:Zhukov V.P., Osipov D.А., Otwinowski H., Urbaniak D.

Research results of influence of volume mass of crosslinked and foamed sorbents on the basis of secondary high-impact polystyrene with bitumen and zinc stearate upon their sorption capacity are represented. The mechano-chemical synthesis of foamed polymeric sorbents was carried out on the extruder with a three zone material cylinder. Azodicarbonamide was used as foaming agent and dicumyl peroxide was used as crosslinking agent. Foam polymer sorbents have a high buoyancy and hydrophobicity. This circumstance contributes to increasing the selectivity of sorption process of oil and oil products from water surface. The sorption capacity was determined by gravimetric method according to difference between sorbent weights before and after sorption. It was shown that petroleum are better sorbed on foamed polymeric sorbents with low volume weight and greater diameter of closed-celled structures. In the same time the diesel fuel sorbed well on sorbents with relatively high volume weight and accordingly lesser diameter of pores and cells. Petroleum oils are most effectively sorbed on foamed polymeric sorbents which volume weight and cells diameter are interim in comparison with sorbents for sorption of petroleum and diesel fuel. It was determined that rate of sorption processes increases with rising of temperature of aqueous medium independently on pores and cells diameter. In this case changing in sorption capacity occurs according to certain regularity depending on sorbate type, volume weight of sorbent and medium temperature. It was shown that obtained sorbents are characterized by capability to multiple regeneration at keeping of high buoyancy, hydrophobicity and sorption capacity on petroleum and oil products.
