Intervenção Federal - Municípios - Estado-Membro
Authors: Brindeiro Geraldo
Published: May 2018

- O cumprimento das decisões judiciais irrecorríveis impõe-se ao poder público como obrigação constitucional inderrogável.- A exigência de respeito incondicional às decisões judiciais transitadas em julgado traduz imposição constitucional, justificada pelo princípio da separação de poderes e fundada nos ostulados que informam, em nosso sistema jurídico, a própria concepção de Estado Democrático de Direito.- O dever de cumprir as decisões emanadas do Poder Judiciário, notadamente nos casos em que a condenação judicial tem por destinatário o próprio Poder Público, muito mais do que simples incumbência de ordem processual, representa uma incontornável obrigação institucional a que não se pode subtrair o aparelho de Estado, sob pena de grave comprometimento dos princípios consagrados no texto da Constituição da República.- A desobediência à ordem ou à decisão judicial pode gerar, em nosso sistema jurídico, gravíssimas conseqüências, quer no plano penal, quer no âmbito político-administrativo (possibilidade de impeachment), quer, ainda, na esfera institucional (decretabilidade de intervenção federal nos Estadosmembros ou em Municípios situados em Território Federal, ou de intervenção estadual nos Municípios).- Impossibilidade e decretação de intervenção federal em Município localizado em Estado-membro.- Os Municípios situados no âmbito dos Estados-membros não se expõem à possibilidade constitucional de sofrerem intervenção decretada pela União Federal, eis que, relativamente a esses entes municipais, a única pessoa política ativamente legitimada a neles intervir é o Estado-membro. Magistério da doutrina.- Por isso mesmo, no sistema constitucional brasileiro, falece legitimidade ativa à União Federal para intervir em quaisquer Municípios, ressalvados, unicamente, os Municípios "localizados em Território Federal ...

Bioethanol production using vegetable peels medium and the effective role of cellulolytic bacterial (Bacillus subtilis) pre-treatment
Authors: Promon Salman Khan , Kamal Wasif , Rahman Shafkat Shamim , Hossain M. Mahboob , Choudhury Naiyyum
Published: May 2018

Background: The requirement of an alternative clean energy source is increasing with the elevating energy demand of modern age. Bioethanol is considered as an excellent candidate to satiate this demand.

Methods:Yeast isolates were used for the production of bioethanol using cellulosic vegetable wastes as substrate. Efficient bioconversion of lignocellulosic biomass into ethanol was achieved by the action of cellulolytic bacteria (Bacillus subtilis).  After proper isolation, identification and characterization of stress tolerances (thermo-, ethanol-, pH-, osmo- & sugar tolerance), optimization of physiochemical parameters for ethanol production by the yeast isolates was assessed. Very inexpensive and easily available raw materials (vegetable peels) were used as fermentation media. Fermentation was optimized with respect to temperature, reducing sugar concentration and pH.

Results:It was observed that temperatures of 30°C and pH 6.0 were optimum for fermentation with a maximum yield of ethanol. The results indicated an overall increase in yields upon the pretreatment ofBacillus subtilis; maximum ethanol percentages for isolate SC1 obtained after 48-hour incubation under pretreated substrate was 14.17% in contrast to untreated media which yielded 6.21% after the same period. Isolate with the highest ethanol production capability was identified as members of the ethanol-producingSaccharomycesspecies after stress tolerance studies and biochemical characterization using Analytical Profile Index (API) ® 20C AUX and nitrate broth test. Introduction ofBacillus subtilisincreased the alcohol production rate from the fermentation of cellulosic materials.

Conclusions:The study suggested that the kitchen waste can serve as a raw material in ethanol fermentation.
A multi-center prospective cohort study to evaluate the effect of differential pricing and health systems strengthening on access to medicines and management of hypertension and diabetes in Ghana: A study protocol
Authors: Mobula Linda Meta , Sarfo Stephen , Arthur Lynda , Burnham Gilbert , Plange-Rhule Jacob , Ansong Daniel , Gavor Edith , Ofori-Adjei David
Published: May 2018

Background: There is evidence to suggest that the prevalence of non-communicable diseases (NCDs), in particular cardiovascular diseases and diabetes, are being recognized as forming a substantial proportion of the burden of disease among populations in Low- and Middle-Income Countries (LMICs).  Access to treatment is likely a key barrier to the control and prevention of NCD outcomes.  Differential pricing, an approach used to price drugs based on the purchasing power of patients in different socioeconomic segments, has been shown to be beneficial and leads to improved access and affordability.

Methods: This is a quasi-experimental study, with a pragmatic trial design, to be conducted over the course of three years. A mixed methods design will be used to evaluate the effects of health systems strengthening and differential pricing on the management of diabetes, hypertension and selected cancers in Ghana. A public private partnership was established between all sites that will receive multi-level interventions, including health systems strengthening  and access to medicines interventions.

Study populations and sites: Study participants will include individuals with new or previously diagnosed hypertension and diabetes (n=3,300), who present to two major referral hospitals, Komfo Anokye Teaching Hospital and Tamale Teaching Hospital, as well as three district hospitals, namely Kings Medical Centre, Agogo Presbyterian District Hospital, and Atua Government Hospital.

Discussion: The objective of this study aims to test approaches intended to improve access to drugs for the treatment of hypertension and diabetes, and improve disease control. Patients with these conditions will benefit from health systems strengthening interventions (education, counseling, improved management of disease), and increased access to innovative medicines via differential pricing.

Pilot programs also will facilitate health system strengthening at the participating institutions, which includes training of clinicians and updating of guidelines and production of protocols for the treatment of diabetes, hypertension and cancer.
Oscar PR Girl: How interconnected social media platforms humanized the Oscar de la Renta brand identity
Authors: Smith Kaitlyn M. , McClain Jordan M. , Lascity Myles Ethan
Published: May 2018

This project examines how the social media persona Oscar PR Girl was constructed and humanized as a luxury brand identity for Oscar de la Renta. To understand this issue, the article considers branding literature focused on luxury brand marketing via social media, then details a textual analysis of Oscar PR Girl content across three social media accounts (Instagram, Twitter and Pinterest) between 1 February and 31 March 2015. The findings of this analysis address how Oscar PR Girl’s messages on various social media accounts interacted with each other to become a unified branding tool. This exploration comes at a time when luxury marketers grapple with how to participate in social media platforms without diminishing brand identity and exclusivity.

Développé: Katherine Dunham’s diasporic dance
Authors: Olmstead Amanda
Published: May 2018

This piece focuses on the dance style and methodology developed by Katherine Dunham combining African diasporic dance traditions with Eurocentric dance traditions. Dunham was able to use this new choreographic technique to subvert the white-patriarchal gaze and create a space that forever changed the Broadway stage. In the early 1930s, she travelled to the Caribbean to complete ethnographic research on African-rooted dance styles on the islands. She was then able to bring these back to the United States and slowly integrate them into the choreography for her concert dance piece La’Ag’ya (1938) and her choreography for the hit musicals Pins and Needles (1940) and Cabin in the Sky (1940). Her innovation discovered and exploited the possibilities for subversion or transgression within dance using a hybrid movement style performed by black bodies in order to create an opportunity for an authentic black musical theatre.
Hematological parameters and remission induction of childhood acute lymphoblastic leukemia
Authors: Perdani Roro Rukmi Windi , Sudarmanto Bambang
Published: May 2018

Background High-risk acute lymphoblastic leukemia (ALL) is one of the most common childhood malignancies in Indonesia. Many factors can inhibit the induction of remission. Hematological parameters are usually not normal. Identification of corresponding factors is important to increase the likelihood of successful inductions.Objective To assess for associations between hematological parameters and induction of remission in children with acute lymphoblastic leukemia.Methods Data were collected from medical records of ALL patients hospitalized in the Pediatric Ward at Dr. Kariadi Hospital from May 2014 – May 2016. Dependent variables were hemoglobin, leukocytes, platelets, and absolute neutrophil count (ANC) levels; the independent variable was induction of remission.Results Out of 55 patients, 33 (60%) had anemia, 6 (10.9%) had leukocytosis, and 1 (1.8%) had hyperleukocytosis, whereas 9 (34.5%) had leukopenia and 29 (52,7%) had normal leukocyte levels. Thirty-one subjects (56.4%) had thrombocytopenia, 15 (27.3%) had thrombocytosis, and only 9 (16.4%) patients had normal platelet counts. There were 29 (52.7%) with absolute ANC > 500, whereas 26 (47.3%) had ANC level ≤ 500. Most patients (80%) experienced remission induction, while 20% did not. There were significant associations between ANC level and induction of remission (P=0.010) as well as between platelet level and induction of remission (P= 0.033). Regression logistic test revealed that ANC level ≤ 500 was associated with a 7-fold lower remission event compared to ANC level > 500 (RR 7.147; 95%CI 1.38 to 37.14).Conclusion Lower ANC level (≤ 500) was significantly associated with lower remission compared to higher ANC level (> 500).

Abstrakt: Přehledová studie mapuje vybrané výzkumy predikční validity zkoušek zakončujících středoškolské vzdělávání a přijímacích testů na vysoké školy. Predikční validita je důležitou vlastností testu a vyjadřuje jeho schopnost předpovídat budoucí úspěch. Mezi nejužívanější prediktory patří právě výsledky v přijímacích testech a hodnocení ze středních škol, přičemž porovnávání jejich vlivu je jedním z často diskutovaných témat. Ač existuje několik kritérií akademického úspěchu, nejčastěji je využíván studijní průměr během prvního ročníku studia, postup do druhého ročníku nebo úspěšné dokončení studia. Analyzované studie jsou rozděleny do kapitol podle jejich hlavního cíle, od studií zaměřujících se na středoškolské zkoušky ke studiím zjišťujícím predikční validitu přijímacích zkoušek. Dalším kritériem řazení je země původu dat. Samostatná část je věnována výzkumům v České republice. Ze studií jednoznačně vyplývá, že využití přijímacích testů i prospěchu ze střední školy je v rámci přijímacích řízení na vysoké školy opodstatněné. Oba tyto parametry dokáží předpovědět, zda student bude ve studiu úspěšný i zda studium zdárně dokončí, přičemž nejlepších výsledků bývá dosaženo při zohlednění obou těchto parametrů současně.Klíčová slova: predikční validita, průměr známek, středoškolský prospěch, přijímací testy, prediktor, akademický úspěch, prospěch na VŠ.
Shadows Between the Signs
Authors: Howard David Brian
Published: May 2018

The following experimental text is drawn from my most recent research project War Machines: Utopia and Allegorical Poetics in the Twenty-First Century. The project is an adaptation of the allegorical poetics developed by the French poet Charles Baudelaire in his scathing attacks on the sweeping transformation of Paris being conducted by Napoleon III’s right-hand man, Baron Haussmann. This small excerpt from my new book is a demonstration of my critical and poetical re-framing of Benjamin’s work that orients itself more towards the overlooked elements of Benjamin’s Marxism, as well as his “weak messianic” perspective, in order to re-assert a more radical orientation of his poetics and critical method with the utopian perspectives found in the work of that other great Marxist outlier of the twentieth century, Ernst Bloch, especially as outlined in his book, The Principle of Hope. Thus, unlike the postmodern appropriation of Baudelaire and Benjamin, I want to propose the possibility of bridging the gap between allegorical poetics, Marxism, and utopianism once again as a rigorous, critical option in the twenty-first century.

Authors: Krishnaraja A. R. , Kandasamy S.
Published: May 2018

This study focuses to develop a new hybrid Engineered Cementitious Composite (ECC) and assesses the performance of a new hybrid ECC based on the steel short random fiber reinforcement. This hybrid ECC aims to improve the tensile strength of cementitious material and enhance better flexural performance in an RC beam. In this study, four different mixes have been investigated. ECC with Poly Vinyl Alcohol (PVA) fiber and PolyPropylene (PP) fiber of 2.0% volume fraction are the two Mono fiber mixes; ECC mix with PVA fiber of 0.65% volume fraction hybridized with steel fiber of 1.35% volume fraction, PP fiber of 0.65% volume fraction hybridized with steel of 1.35% volume fraction are the two additional different hybrid mixes. The material properties of mono fiber ECC with 2.0 % of PVA is kept as the reference mix in this study. The hybridization with fibers has a notable achievement on the uniaxial tensile strength, compressive strength, Young’s modulus, and flexural behavior in ECC layered RC beams. From the results, it has been observed that the mix with PVA fiber of 0.65% volume fraction hybrid with steel fiber of 1.35% volume fraction exhibit improvements in tensile strength, flexural strength, and energy absorption. The PP fiber of 0.65% volume fraction hybridized with steel of 1.35% volume fraction mix has reasonable flexural performance and notable achievement in displacement ductility over the reference mix.

Is the genus Potamophylax (Trichoptera: Limnephilidae) highly polymorphic?
Authors: Oláh János
Published: May 2018

The present deprived state of taxonomy gives no appropriate resources for taxonomists to apply more sophisticated phenomic tools and to carry out more appropriate population sampling. Without fine structure analysis of large population samples there is no hope to discover speciation traits and there is no chance to delineate young incipient sibling species with subtle but stable shape divergences. Phylogenetic species complexes of these incipient species are frequently mistaken with species polymorphism. However, historical polymorphism is a sympatric phenomenon based on discontinuous variation inside a panmictic population and not between geographically isolated populations. I continue to consider Potamophylax mista (Navas, 1918) a valid species following the evidence given by Oláh et al. (2013).

Published: May 2018

The main scope of the article is the development of a computer system, which should give advices at problem of cooper alloys manufacturing. This problem relates with choosing of an appropriate type of bronze (e.g. the BA 1044 bronze) with possible modification (e.g. calcium carbide modifications: Ca + C or CaC2) and possible heat treatment operations (quenching, tempering) in order to obtain desired mechanical properties of manufactured material described by tensile strength - Rm, yield strength - Rp0.2 and elongation - A5. By construction of the computer system being the goal of presented here work Case-based Reasoning is proposed to be used. Case-based Reasoning is the methodology within Artificial Intelligence techniques, which enables solving new problems basing on experiences that are solutions obtained in the past. Case-based Reasoning also enables incremental learning, because every new experience is retained each time in order to be available for future processes of problem solving. Proposed by the developed system solution can be used by a technologist as a rough solution for cooper alloys manufacturing problem, which requires further tests in order to confirm it correctness.

Some characterizations of super-strongly clean rings are given.
On a Generalization of Weakly Supplemented Modules
Authors: Nişanci Türkmen Burcu , Türkmen Ergül
Published: May 2018

In this paper, over an arbitrary ring we define the notion of weakly radical supplemented modules (or briefly wrs-module), which is adapted from Zöschinger’s radical supplemented modules over a discrete valuation ring (DVR), and obtain the various properties of these modules. We prove that a wrs-module having a small radical is weakly supplemented. Moreover, we show that a ring R is left perfect if and only if every left R-module is wrs. Also, we prove that every wrs-module over a DVR is radical supplemented.

The influence of a radiated heat exchanger surface on heat transfer
Authors: Morel Sławomir
Published: May 2018

The experiment leads to establish the influence of radiated surface development heat exchangers on the values of heat flux transferred with water flowing through the exchangers and placed in electric furnace chamber. The values of emissivity coefficients are given for the investigated metal and ceramic coatings. Analytical calculations have been made for the effect of the heating medium (flame) – uncoated wall and then heating medium (flame) – coated wall reciprocal emissivity coefficients. Analysis of the values of exchanged heat flux were also realized. Based on the measurement results for the base coating properties, these most suitable for spraying the walls of furnaces and heat exchangers were selected, and determined by the intensification of heat exchange effect. These coatings were used to spray the walls of a laboratory waste-heat boiler, and then measurements of fluxes of heat absorbed by the cooling water flowing through the boiler tubes covered with different type coatings were made. Laboratory tests and calculations were also confirmed by the results of full-scale operation on the metallurgical equipment.

Authors: Dražić Gordana , Aranđelović Mirjana , Milovanović Jelena , Jureková Zuzana , Marišová Eleonóra
Published: May 2018

In accordance with priorities of sustainable development in Serbia, production and use of biomass is crucial for provision of annually renewable national sources of energy and for environmental quality conservation. Rural development has typically focused on improving agricultural production and promoting market orientation, however, as the examples of other countries in the EU accession process have shown (e.g. Slovakia), such an approach could threaten the survival of rural population. Biomass production is one of the key sectors with significant potential for diversification of rural economy. The results of multiannual research work supported by the Ministry of Education, Science and Technological Development of the Republic of Serbia through national scientific projects and several international initiatives are summarized in this paper. The research activities focus on Miscanthus × giganteus Greef et Deu. The production potentials of miscanthus on fertile and degraded soils were investigated since 2009 in experimental plots established on moderate and extremely degraded lands in Serbia, applying various agrotechnical measures in different ecological conditions. The results show that fertile agricultural land as well as moderate degraded areas provide suitable conditions for miscanthus biomass and viable rhizomes production for energy and ecoremediation purposes.
Criteria For Felling Maturity Of Poplar Clones Grown For Energy Use
Authors: Petráš Rudolf , Mecko Julian , Petrášová Viera
Published: May 2018

Poplar clones reach a big advantage over other forest tree species in the production of large amounts of above-ground biomass in a relatively short time. To increase the efficiency of production during their short life cycle, it is necessary to optimize age of their felling maturity. It should be carried out in the stands age when its average production is highest. Mathematical models of yield tables were used to derive this production. Above-ground biomass production was expressed in natural units, volume (m3 ha−1) and the capacity of calorific value (GJ ha−1), but also in financial yield (€ ha−1) from the sale of timber assortments including energy chips from smallwood. In terms of financial yield, Robusta stands are mature between 23 and 35 years and I-214 stands between 18 and 32 years. Main financial yield per year, on average 200–1900 € ha−1, is expected from the production of assortments designed for classic industrial processing. Its increase by 50 to 100 € ha−1 is expected to be achieved by supplemental smallwood processing to energy chips. In terms of volume production and capacity of combustion heat, stands are mature about 5–7 years earlier.

We present a case of a 51 year old multiple myeloma patient due to the complexity of his disease. After prior high dose therapy with cardiotoxic cytostatic drugs patient developed cardiac arrest due to a ventricular fibrillation. Cardiopulmonary resuscitation was successfully but the hematologist stopped the cytostatic treatment due to the high cardiac risk.

The only way to control his myeloma was an autologous transplantation but this also had a very high cardiotoxic potential due to the high dose of Melphalan administered as conditioning treatment.

We present the difficulties and the results of this complex case. It also arises the potential beneficial effects of the megadose of stem cells on the myocardium but this needs further studies.

Published: May 2018

In this study nutritional values and seasonal availability of 43 local feed ingredients for pigs in Uganda, were estimated based on nutrient analyses and literature values, information needed to develop low-cost balanced rations for pigs on smallholder farms. Parameters considered were: concentration of ash, neutral detergent fibre (NDF), crude protein (CP), calcium (Ca), phosphorous (P), ether extract (EE), total lysine (Lys), standardized ileal digestible (SID) Lys, standardized total tract digestible (STTD) P (all as % of dry matter [DM]); digestible energy (DE), (kcal kg−1 of DM); and DM concentration. Concentration of DE, total Lys, SID Lys, and STTD P were estimated. Ingredient seasonal availability and relative importance were identified. Ground sun-dried fish (Rastrineobola argentea) had highest estimated DE concentration and Napier grass (Pennisetum purpureum) had lowest (4209 and 535 kcal kg−1 of DM, respectively). Ground sun-dried fish had highest CP and estimated total Lys concentration (59.9 and 6.7% of DM, respectively) and banana peel (Musa sapientum), had lowest (5.21 and 0.08% of DM, respectively). Milled ingredients sampled here had higher ash than in the literature (e.g. ground sun-dried fish 58.1 vs 15.9% of DM) likely indicating sand contamination. There were 3 seasons of availability of ingredients. Banana peel, maize bran, and sweet potato vine (Ipomoea batatas) were ranked highest; and commercially-prepared ration, and kale/collard greens (Brassica oleracea var. acephala), were ranked lowest as potential feed ingredients. Ingredients with nutritional profiles suitable for pigs are available but some only in certain seasons. Estimated nutritional values may assist in ration formulation.

Published: May 2018

Milk consumption is important in the diet of all age groups because it provides important nutrients that are essential for humans. Children are the largest consumers of milk, thus, it’s very important that milk is free of toxic compounds that can be harmful for humans. Aim of the study was to determine the physico-chemical characteristics of some samples of milk powder for different stage of baby growing and for some samples of fresh milk: raw cow’s milk, milk trade and UHT type. The following physico-chemical properties: density, pH, acidity, the presence of acetone, enzymes, antiseptics, dry substance, the ash, total fat, saponification and peroxide index, total nitrogen and protein content were determined. Comparing the values of acidity for analyzed samples it can be concluded that the powder milk acidity value is much lower than the fresh milk. The presence of antiseptics and acetone was not identified, and amylase and peroxidase were found only in raw cow's milk. The highest protein content was found for milk powder (27.22%).
Kinetics of the thermal decomposition of pine needles
Authors: Dhaundiyal Alok , Gangwar Jitendra
Published: May 2018

A kinetic study of the pyrolysis process of pine needles was examined using a thermogravimetric analyser. The weight loss was measured in nitrogen atmosphere at a purge flow rate of 100 ml/min. The samples were heated over a range of temperature of 19°C–600°C with a heating rate of 10°C/min. The results obtained from the thermal decomposition process indicate that there are three main stages: dehydration, active and passive pyrolysis. The kinetic parameters for the different samples, such as activation energy and pre-exponential factor, are obtained by the shrinking core model (reaction-controlled regime), the model-free, and the first-order model. Experimental results showed that the shrinking model is in good agreement and can be successfully used to understand degradation mechanism of loose biomass. The result obtained from the reaction-controlled regime represented actual values of kinetic parameters which are the same for the whole pyrolysis process; whereas the model-free method presented apparent values of kinetic parameters, as they are dependent on the unknown function ϕ(C), on the sum of the parameters of the physical processes, and on the chemical reactions that happen simultaneously during pyrolysis. Experimental results showed that values of kinetic constant from the first-order model and the SCM are in good agreement and can be successfully used to understand the behaviour of loose biomass (pine needles) in the presence of inert atmosphere. Using TGA results, the simulating pyrolysis can be done, with the help of computer software, to achieve a comprehensive detail of the devolatilization process of different types of biomasses.

Authors: Adorján Anna , Fáczányi Zsuzsanna , Sipos Andrea
Published: May 2018

Our PhD researches include brownfield revitalization,1 the application of the methods of interim utilizations on greeneries,2 and the formation background and potential of community gardens.3 We compared our systems of criteria in hope of extensive research conclusions. In order to trace the urban development possibilities in Budapest, we analysed brownfield revitalizations where the interim utilizations included allotment gardens, too. We concluded that such developments are likely to create environmental and social added value. Early results of the valorization process are important by themselves, but the perpetuation of interim land utilization holds even greater values.
Postmodern landscape architecture: theoretical, compositional characteristics and design elements with the analysis of 25 projects
Authors: Eplényi Anna , Oláh-Christian Brigitta
Published: May 2018

This paper endeavours to highlight three aspects of postmodern landscape design: theoretical basis, composition and design elements. Postmodern theories, philosophy influenced the language of the postmodern landscape architecture and got materialized in the use of narratives, eclecticism, the Rhizome-principle. Postmodern landscape composition can be associated with anti-hierarchy, unusual structures, landforms, and playful moods. Postmodern design elements consist of the strong graphical use of colour and pavements, bizarre water features, unusual structures and buildings, postmodern sculptures and thematic garden details. 25 analysed projects try to capture the essence of postmodernism in landscape architecture as well as to reveal points of intersection within these projects.

The aim of the research was to record the recollections of the still living eyewitnesses of the events in the fall of 1944 in Cluj and its surroundings, in settlements that belonged to the southern part of Transylvania during World War II. Several hours of interviews were made in the villages of the regions of Ţara Călatei (Kalotaszeg) and the Transylvanian Plain (Mezőség), and the lecture presents a synthesis of these interviews. They address issues like deportation, atrocities, fleeing, arm usage, Soviet and Romanian detention camps, adventurous escapes, etc.
Fibonacci words in hyperbolic Pascal triangles
Authors: Németh László
Published: May 2018

The hyperbolic Pascal triangle HPT
4,q (q ≥ 5) is a new mathematical construction, which is a geometrical generalization of Pascal’s arithmetical triangle. In the present study we show that a natural pattern of rows of HPT
4,5 is almost the same as the sequence consisting of every second term of the well-known Fibonacci words. Further, we give a generalization of the Fibonacci words using the hyperbolic Pascal triangles. The geometrical properties of a HPT
4,q imply a graph structure between the finite Fibonacci words.
