Published: August 2019

Information on the state of the Federal budget (surplus or deficit) is insufficient for an adequate, complete assessment of the state of the country’s economy. The budget deficit does not always speak only about the negative impact on the economy. From the point of view of economic theory, a budget surplus does not always mean that the policy of the state is successful and competent. The budget surplus indicates that the state has left free money that was not used to Finance important projects, which means the underutilization of potential. It is necessary to analyze the Federal budget deficit: what exactly is its cause, and most importantly — what sources of funding are attracted.

BACKGROUND

The Islet Autoantibody Standardization Program (IASP) aims to improve the performance of immunoassays measuring type 1 diabetes (T1D)-associated autoantibodies and the concordance of results among laboratories. IASP organizes international interlaboratory assay comparison studies in which blinded serum samples are distributed to participating laboratories, followed by centralized collection and analysis of results, providing participants with an unbiased comparative assessment. In this report, we describe the results of glutamic acid decarboxylase autoantibody (GADA) assays presented in the IASP 2018 workshop.

METHODS

In May 2018, IASP distributed to participants uniquely coded sera from 43 new-onset T1D patients, 7 multiple autoantibody-positive nondiabetic individuals, and 90 blood donors. Results were analyzed for the following metrics: sensitivity, specificity, accuracy, area under the ROC curve (ROC-AUC), partial ROC-AUC at 95% specificity (pAUC95), and concordance of qualitative and quantitative results.

RESULTS

Thirty-seven laboratories submitted results from a total of 48 different GADA assays adopting 9 different formats. The median ROC-AUC and pAUC95 of all assays were 0.87 [interquartile range (IQR), 0.83–0.89] and 0.036 (IQR, 0.032–0.039), respectively. Large differences in pAUC95 (range, 0.001–0.0411) were observed across assays. Of formats widely adopted, bridge ELISAs showed the best median pAUC95 (0.039; range, 0.036–0.041).

CONCLUSIONS

Several novel assay formats submitted to this study showed heterogeneous performance. In 2018, the majority of the best performing GADA immunoassays consisted of novel or established nonradioactive tests that proved on a par or superior to the radiobinding assay, the previous gold standard assay format for GADA measurement.

Published: August 2019

The aim of the study was to evaluate the influence of different surface post-etching treatments in flexural strength, contact angle and surface roughness of a lithium disilicate ceramic. 60 bars (16x2x4mm) were divided in six groups (n=10): C, no treatment; HF, hydrofluoric acid for 20s (HF) + washing (60s), drying (30s); HFL, HF + washing (60s), drying (30s) and luting; HFNL, HF + washing (60s) + neutralization with sodium bicarbonate (SB) for 40s + washing (5s), drying (30s) and luting; HFUL, HF + washing (60s) + ultrasonic bath (UB) for 4 min, drying (30s) and luting; HFNUL, HF + washing (60s) + SB (40s) + UB (4 min) and luting. The bars were submitted to three-points flexural strength test. To analyze roughness and contact angle 25 ceramic blocks (12x7x7 mm) were divided into five groups (n=5): C - no treatment; HF - HF ; HFU - HF and UB for 5 min ; HFN - HF and SB; HFNU - HF, UB and SB. A scanning electron microscope (SEM) analysed the surface of the samples. ANOVA one-way statistical analysis was done for comparison of results. There was no statistical difference for flexural strength (p-value=0.15) and for surface roughness (p-valor=0.15). However, it was obtained statistically significant difference for contact angle (p-valor=0.00). SEM images showed precipitates after the acid etching, which were removed by post-etching treatments. It can be concluded that the different post-etching surface treatments did not increase the flexural strength, surface roughness and ceramic wetting, but it influenced the SEM images.

Published: August 2019

Aim: To investigate the prevalence of the early unitary loss of deciduous and the need for space maintainer in the posterior region, of the band-loop type. Methods: The clinical examination of 568 children between 6 and 12 years of age in mixed dentition was performed in two municipal schools. After the diagnosis of premature loss of one or two deciduous molars (unilateral, one or both arches, respectively), without successors initiating the eruptive process in the oral cavity, the child was referred to the Clinical School of Dentistry of UESPI (CSD ) for installation of the band-handle space maintainer. Results: The prevalence of early molar loss was 4.04%, the etiological factor of which was dental caries for all sample. Only 13 attended the CEO for detailed examination. After radiographic examination, it was verified that 8 did not need space maintainers because they were approximately 2/3 of the permanent successors root formation. In 5 children was placed the maintainer of space, band-handle, who are being supervised every 3 months until the eruption of the permanent successors. Conclusion: The prevalence of early premolar molar loss was 4.04% with no statistical difference between genders. The use of space maintainers after the early loss of a deciduous tooth is a preventive measure of malocclusion, being the band-loop appliance an excellent choice after loss of the deciduous unilateral molar.

Published: August 2019

The objective of this study was to evaluate the alteration of the optical properties of bulk Fill resin-based composites after 2 years of simulated toothbrushing. Three high-viscosity bulk fill resin composites and one conventional sculptable resin composite (control) were analyzed. Five specimens of each resin composite were prepared, and roughness, color, translucency and gloss were evaluated initially and after one and two years of simulated toothbrushing. The specimens were submitted to electric simulated toothbrushing (14600 strokes/100g) using a commercially available toothbrush with soft fibers and toothpaste slurry in a proportion of 1:2 by weight. The brushing scheme was of 40 cycles per day (2 cycles per second / 280 cycles in a week). The optical properties and the roughness data were analyzed by a multifactor analysis of variance (MANOVA) and a Tukey post hoc test. The baseline and final values of Ra and Sa were submitted to linear regression analyses, all of which were performed at a significance level of p=0.05. Gloss and roughness presented statistical differences between the resin-time interactions in all composite resins. The gloss (72.5%) and roughness (89.4%) worsened significantly after brushing, but the authors didn’t find statistically significant differences when evaluating translucency and color. Based in the results, it could be concluded that the simulated brushing degraded the brightness and roughness of the used high-viscosity bulk fill composites.
Barths »Tambacher Vortrag« und Bonhoeffers »tiefe Diesseitigkeit«. Bahnbrechende Impulse für Kirche und Gesellschaft noch heute
Authors: Welker Michael
Published: August 2019

This paper examines two ingenious theological contributions by Karl Barth and Dietrich Bonhoeffer: the famous Tambach lecture by Barth, given 100 years ago, and the concept of the »deep worldliness« (tiefe Diesseitigkeit) of the Christian faith developed by Bonhoeffer in his prison letters. It shows why even today both contributions have orienting power for church and society in situations of radical transition and change. Both contributions derive their strength from the fact that they have a clear theological and at the same time realistic orientation, Christologically and implicitly also pneumatologically founded. On this base they link a serious theology and a vigilant critical contemporaneity.

Published: August 2019

This study evaluated the variations in temperature and dry matter content in Tifton 85 bermudagrass and Wrangler grass hay stored under different environmental conditions. The fungal and mycotoxin populations in the hay production area were also evaluated. Fifty samples (30 hay bales, ten samples of organic matter [OM], and ten samples of grass [G] before baling) were used in a completely randomized design and factorial scheme with ten treatments (a combination of two classes of G: Tifton 85 bermudagrass and Wrangler grass) and three storage systems: a covered shed without side walls, covered with a clear tarp; an open environment covered with a double-sided tarp; and a ventilated closed shed. Four additional treatments, five replications, and one sample per experimental unit completed the study design. The environment influenced the temperature of the Tifton 85 bermudagrass and Wrangler grass bales, and the dry matter content of the bales during the evaluated period was above the recommended limit (800 g kg-1). The genus Penicillium occurred with the highest frequency in the Wrangler grass stored under a double-sided tarp (6.13 log CFU g-1). In the additional treatment, the OM deposited in the soil of the Wrangler grass production area exhibited a greater occurrence of the fungus Fusarium (4.66 log CFU g-1) and of the mycotoxin zearalenone (ZEA; 594.2 μg kg-1). The hay stored in the shed with a clear tarp exhibited more aflatoxin (AFLA) and deoxynivalenol (DON). The concentration of mycotoxins varied across the storage environments and between the stored species; however, the shed storage system used in hay production might also be a source of hay contamination via the incorporation of decomposing OM with mycotoxins in the hay.

The State of Rio Grande do Sul is a major producer of grapes in Brazil, highlighting the Serra Gaúcha as the main producing region. In the pursuit of good quality in grapes it is essential the control of pests, especially insects. This study highlights the incidence of wasps, which cause serious damage at harvest time. This study aimed to characterize the community of social wasps (Hymenoptera, Vespidae) through faunal analysis and to examine the relationship of these insects with injuries to the grape berries in vineyards of Bento Gonçalves, Rio Grande do Sul State. Therefore, active search were made in January and February 2014, followed by analysis of frequency, constancy, abundance, dominance and diversity. Ten species of wasps were able to use grape berries as food. The two dominant species were Polybia ignobilis and P. minarum, however, Synoeca cyanea has greater ability to break the intact berries. Other three species, Polistes cavapytiformis, P. versicolor and Brachygastra lecheguana, were also able to break the skin of grapes, but of damaged berries.

Published: August 2019

Some areas of knowledge are usually related to a high degree of abstraction involved in the object studied. In the case of the embryology study, for instance, the students’ learning difficulties are recurrent due to a lack of didactic resources, which may aid the interpretation process of the figures presented in related literature. Based on the motivation to improve university education, specially  in the area of biological sciences, the present work aims to represent in three dimensions, stages of the human embryological development. SolidWorks 3D modeling software was used, as well as didactic material related to the subject of embryology, conception and human development, such as books, atlases and scientific papers. There were designed, in 3D software, models representing the stages of human embryonic development. This means of production allowed the elaboration of exclusive anatomic models, with low cost (less than R$100,00 for more than 10 parts) and ease of visual interpretation. The models were designed in scale, such that it was possible to compare models that represent distinct periods of ontogenic development. It was possible to contribute to an improvement in the understanding of the topic of embryology for students with major related to health, through the visualization, in three dimensions, of models that are sometimes very expensive as physical pieces, or even nonexistent in market.

Direito Fundamental à Liberdade Religiosa de Crianças e Adolescentes
Authors: Provin Alan Felipe , Borteze Audrey Pongan
Published: August 2019

O presente artigo objetiva a análise do direito à liberdade religiosa de crianças e adolescentes, tendo em vista que este é consagrado com um dos direitos fundamentais previstos na Constituição Federal de 1988. A pesquisa possui como problemática o questionamento acerca da possibilidade de atribuir o fundamento da liberdade de convicção religiosa às crianças e adolescentes, ainda que em conflito com o direito à vida, considerando a incapacidade civil dos menores. Ademais, analisa também os direitos constitucionais e princípios aplicados aos menores à luz da doutrina da proteção integral, bem como expõe o conflito entre direitos fundamentais e aborda as posições dos Tribunais quanto ao tema. Em termo de metodologia, utilizou-se a pesquisa qualitativa, indutiva e bibliográfica. Ao final dos estudos, concluiu-se que, em que pese o direito à vida e a liberdade religiosa serem direitos fundamentais, com hierarquia idêntica, há casos em que é permitida a relativização de um direito em prol do outro, devendo ser analisado cada caso em concreto.

Acceso de los Consumidores a la Justicia en la Unión Europea y Mercado Globalizado
Authors: Palao Moreno Guillermo
Published: August 2019

El consumidor europeo cuenta con una desigual atención, por parte del legislador de la Unión Europea, a la hora de tutelar su acceso a la justicia en relación a las controversias transfronterizas en las que pudiera verse involucrado. Una protección que, aunque atendida de cara a su acceso a la justicia al respecto de las situaciones conectadas con el mercado interior UE, no es tan evidente en relación con los casos extra-europeos, que además se han visto multiplicados tras la irrupción de la Sociedad de la Información. En este sentido, el presente artículo tiene por finalidad, en primer lugar, poner de manifiesto esta situación de desigual tutela, tanto con respecto al recurso a los tribunales ordinarios (competencia judicial internacional), como al respecto de los mecanismos alternativos de resolución de controversias, en esta materia (i.e. mediación y arbitraje). Junto a ello, este artículo igualmente realiza propuestas concretas que, al margen de destacar la importancia que tiene en este ámbito la acción de la codificación internacional, señala las opciones con las que cuenta el legislador europeo y que permitirían facilitar el acceso a la justicia de los consumidores cuando actúan en un mercado globalizado.

Published: August 2019

This study aims to investigate the formation process slang of Australian English. This research employs a qualitative-descriptive approach. The data of this research are conversation transcripts of Australians consisting three males and one female and being analysed analytically to find the use of slang. Observational technique was used to gather the data. The researcher taped the conversation and transcribed them to make the data analysis easier. Slang is formed into a morphological and semantic process. The morphological processes consist of derivation, clipping, blending, acronym, and alliteration. The semantic process consists of generalization, metaphor, specialization, and arbitrary process. The use of slang affects the society in terms of social and communication function. Knowing this intensely helps non natives to get close and increase more understanding in communicating with Australians.

The study investigated the integration of information communication and technology (ICT) with library instruction (LI) in Clifford University Owerrinta (CLU), Abia State, Nigeria. The study adopted total enumeration method with a population of 124 first year students of 2016/2017 academic session. Two instruments were developed and validated by two professors in the field of Library and Information Science with a reliability result of 0.82 and 0.84 respectively using Cronbach alpha procedure. The instruments were administered face-to-face to the same respondents who registered for the course in the first and second semesters with 100 per cent participation. The finding showed that a change from the traditional method of instruction to an inclusive LI with ICT integration has a significant effect on students’ use of ICT tools and related IT facilities in private university. The study recommended that ICT-based courses should be inculcated in LI curriculum; ICT tools such as projector, interactive board, computers, laptops and Internet connection should be made available for use during LI course while librarians should support and instruct students to acquire ICT skill in order to use ICT-based library information resources effectively.

Published: August 2019

Renewable biomass resources could reduce the dependency on the fossil fuels by conversion of its lignocellulose into bio-fuels and other valuable chemicals. Depolymerisation of lignocellulose, hydrolysis of cellulose to monomer glucose and its subsequent dehydration results 5-hydroxymethyl furfural (HMF). HMF is an important platform chemical for fuels and various other applications. The hydrogenation of HMF results 2, 5-dimethylfuran (DMF), which may be a biofuel with 40 per cent greater energy density than that of ethanol. The homogeneous catalytic method is preferred for lignocellulosic biomass conversion to cellulose, its hydrolysis and further dehydration to HMF. The Cu-Ru/C and related catalysts are preferred for hydrogenation of HMD to 2, 5-dimethylfuran. This review is an attempt to summarise the current research and developments in the field of lignocellulose derived HMF and further conversion to DMF as a potential biofuel.

Published: August 2019

The trans-Himalayan Ladakh region remains cut-off for over six months in a year due to heavy snowfall. Availability of locally grown fresh vegetables is restricted to summer months and therefore, there are seasonal differences in dietary intake of food. Passive solar greenhouse has played a significant role not only in production of leafy vegetables in sub-zero temperature during winter months but also helped in extending the growing season in Ladakh. It is now a common practice to raise vegetable nurseries in spring and grow leafy vegetables during winter months in the greenhouse. Each year an average of 733 greenhouses covering 44313.4 m2 area are being established in Leh district. Passive solar greenhouse structures such as Ladakhi greenhouse, trench, polytrench, polyench, polycarbonate, FRP and polynet have been designed and tested in the inhospitable environment of trans–Himalaya. The greenhouse is used mainly during winter, and majority of farmers (91.7 %) do not use the structures in summer. Insect-pest, irrigation in winter and frequent replacement of cladding materials are the major problems being faced by the farmers in the region. There is a need to improvise the greenhouse design to make it economically viable and technologically feasible to grow a variety of crops, especially during winter months.
Rapid Transfer Alignment of SINS with Measurement Packet Dropping based on a Novel Suboptimal Estimator
Authors: Dai Hongde , Li Juan , Tang Liang , Wang Xibin
Published: August 2019

Transfer alignment (TA) is an important step for strapdown inertial navigation system (SINS) starting from a moving base, which utilises the information proposed from the higher accurate and well performed master inertial navigation system. But the information is often delayed or even lost in real application, which will seriously affect the accuracy of TA. This paper models the stochastic measurement packet dropping as an independent identically distributed (IID) Bernoulli random process, and introduces it into the measurement equation of rapid TA, and the influence of measurement packet dropping is analysed. Then, it presents a suboptimal estimator for the estimation of the misalignment in TA considering the random arrival of the measurement packet. Simulation has been done for the performance comparison about the suboptimal estimator, standard Kalman filter and minimum mean squared estimator. The results show that the suboptimal estimator has better performance, which can achieve the best TA accuracy.
Assessing the Performance of Nano Lubricant on Zinc Aluminium Alloy
Authors: Murugaveni S Parimala , Thyla P R
Published: August 2019

In the field of tribology, Zinc Aluminium (ZA) alloys have been widely investigated for their superior wear characteristics. They were found to be suitable alternatives for bearing bronzes for the operating conditions of high mechanical load and moderate sliding speeds. Addition of nano-particles in the lubricating oil (base oil) to enhance the characteristics of the base oil is known as nano lubrication. In this study, sliding wear behaviour of ZA27 was investigated under dry, base oil and nano oil lubrication conditions, by varying load, sliding distance and sliding speed. With the base oil as SAE 40, nano graphite was added in two step method which was further used to identify the lubrication regime under different lubrication conditions. From the limited study of single melt samples, the results appear that the wear behaviour of ZA27 alloy improved under nano lubrication conditions with reduction in operating temperature. It could be observed from SEM images that the presence of nano-particles reduced scarring and wear, leading to enhancement in the tribological performance of ZA27 alloy.
Behavioural Fault tolerant control of an Omni directional Mobile Robot with Four mecanum Wheels
Authors: Mishra Swati , Sharma Mukesh , Mohan Santhakumar
Published: August 2019

This paper analyses the four-mecanum wheeled drive mobile robot wheels configurations that will give near desired performance with one fault and two faults for both set-point control and trajectory-tracking (circular profile) using kinematic motion control scheme within the tolerance limit. For one fault the system remains in its full actuation capabilities and gives the desired performance with the same control scheme. In case of two-fault wheels all combinations of faulty wheels have been considered using the same control scheme. Some configurations give desired performance within the tolerance limit defined while some does not even use pseudo inverse since using the system becomes under-actuated and their wheel alignment and configurations greatly influenced the performance.
Kłopoty z pamięcią – obraz Bośni i Hercegowiny w przekładzie opowiadania Gurbet ze zbioru Drugi pocałunek Gity Danon Miljenka Jergovicia
Authors: Maćkowiak-Kruczek Maja
Published: August 2019

The paper discusses the issue of cultural memory in a translation of literary text. Based on material of Miljenko Jergović’s story Gurbet and its Polish translation, the article shows how elements of source cultural memory present in the original text are being “lost” when translated to other language and culture. The term of “losing memory” is used figuratively to present the consequences of a translator’s (conscious and/or unconscious) decisions on which specific features of source culture are to be preserved (foreignization) or not (domestication) in the target text. These decisions influence the image of source culture that the reader of the translation can “produce” in the wake of reading. For instance, Polish translation of the story “Gurbet” only partly preserves the memory of Christian-Islamic and Slavic-Ottoman intercultural (or even transcultural) coexistence in the region of Bosnia and Herzegovina, which is one of the main topics and motifs of Miljenko Jergović’s works. As a result, Polish reader cannot produce the same image of the source culture as the reader of the original.
Critical growth elliptic problems involving Hardy-Littlewood-Sobolev critical exponent in non-contractible domains
Authors: Goel Divya , Sreenadh Konijeti
Published: August 2019

The paper is concerned with the existence and multiplicity of positive solutions of the nonhomogeneous Choquard equation over an annular type bounded domain. Precisely, we consider the following equation

$$\begin{array}{}
\displaystyle
-{\it \Delta} u = \left(\int\limits_{{\it\Omega}}\frac{|u(y)|^{2^*_{\mu}}}{|x-y|^{\mu}}dy\right)|u|^{2^*_{\mu}-2}u+f \; \text{in}\;
{\it\Omega},\quad
u = 0 \; \text{ on } \partial {\it\Omega} ,
\end{array}$$

where Ω is a smooth bounded annular domain in ℝN(N ≥ 3),
$\begin{array}{}
2^*_{\mu}=\frac{2N-\mu}{N-2}
\end{array}$, f ∈ L∞(Ω) and f ≥ 0. We prove the existence of four positive solutions of the above problem using the Lusternik-Schnirelmann theory and varitaional methods, when the inner hole of the annulus is sufficiently small.

Authors: Zimmermann Dennis , Beutler Andreas , Brozio Matthias , Freutel Simon , Kosse Philipp , Neumann Cornelius
Published: August 2019

The transition between the light and dark areas of the luminous intensity distribution of a headlamp needs to fulfil statutory regulations. For projection headlamps, adjusting the transition is done by adding a scattering structure to the lens surface. The requirements for the transition are pointed out, and typical problems are presented. A procedure to create such scattering structures in computer-aided design is shown. Improvements to the controls of turning machines for manufacturing are discussed. A reverse engineering process using a high-precision cylindrical coordinate measuring instrument with an optical probe for quality assurance is presented.
A reciprocal branching problem for automorphic representations and global Vogan packets
Authors: Jiang Dihua , Liu Baiying , Xu Bin
Published: August 2019

Let G be a group and let H be a subgroup of G. The classical branching rule (or symmetry breaking) asks: For an irreducible representation π of G,
determine the occurrence of an irreducible representation σ of H in the restriction of π to H. The reciprocal branching problem of this classical branching problem
is to ask: For an irreducible representation σ of H, find an irreducible representation π of G such that σ occurs in the restriction
of π to H. For automorphic representations of classical groups, the branching problem has been addressed by the well-known global Gan–Gross–Prasad conjecture.
In this paper, we investigate the reciprocal branching problem for automorphic representations
of special orthogonal groups using the twisted automorphic descent method as developed in [13]. The method may be applied to
other classical groups as well.

This paper proposes a standardized format for the preparation of process green synthesis reports that can be applied to chemical syntheses of active pharmaceutical ingredients (APIs) of importance to the pharmaceutical industry. Such a report is comprised of the following eight sections: a synthesis scheme, a synthesis tree, radial pentagons and step E-factor breakdowns for each reaction step, a tabular summary of key material efficiency step and overall metrics for a synthesis plan, a mass process block diagram, an energy consumption audit based on heating and cooling reaction and auxiliary solvents, a summary of environmental and safety-hazard impacts based on organic solvent consumption using the Rowan solvent greenness index, and a cycle time process schedule. Illustrative examples of process green synthesis reports are given for the following pharmaceuticals: 5-HT2B and 5-HT7 receptors antagonist (Astellas Pharma), brivanib (Bristol-Myers Squibb), and orexin receptor agonist (Merck). Methods of ranking synthesis plans to a common target product are also discussed using 6 industrial synthesis plans of apixaban (Bristol-Myers Squibb) as a working example. The Borda count method is suggested as a facile and reliable computational method for ranking multiple synthesis plans to a common target product using the following 4 attributes obtained from a process green synthesis report: process mass intensity, mass of sacrificial reagents used per kg of product, input enthalpic energy for solvents, and Rowan solvent greenness index for organic solvents.

An understanding of wood’s moisture-dependent viscoelastic properties under various temperature conditions is important for assessing its utilization and product quality. In this study, we investigated the influence of moisture content (MC) on the orthotropic viscoelasticity of Chinese fir wood (Cunninghamia lanceolata [Lamb.] Hook.) during quenching ranging from 20 to −120°C. The storage modulus (E′) and loss factor (tan δ) of the longitudinal (L), radial (R) and tangential (T) specimens were determined for nine MC levels ranging from 0.6 to 60.0%. The results showed that E′ generally decreased with increasing amount of bound water in all orthotropic directions, regardless of the temperature. In contrast, a sharp increase in E′ was observed at temperatures below 0°C when free water was present, due to the formation of ice within the cell lumens. The γ-relaxation and β-relaxation were observed in the temperature spectrum. A comparison demonstrates that the β-relaxation showed evident grain orientation. When only bound water was present in the wood cell wall, one clear γ-relaxation was found for all orthotropic directions. In contrast, only the high-temperature side of the γ-relaxation was observed in the three anatomic directions in specimens with free water, which might be related to the amorphous wood cell wall coupling with the frozen free water during the quenching process. In addition, the differences in peak temperatures of the γ-relaxation among the three main directions diminished with increasing bound water.
A molecular model for reversible and irreversible hygroscopicity changes by thermal wood modification
Authors: Willems Wim , Altgen Michael , Rautkari Lauri
Published: August 2019

Heat treatment (HT) is a well-known means to reduce the equilibrium wood moisture content (EMC) at a specified relative humidity (RH). EMC is profoundly decreased by the loss of accessible hydroxyl groups (OHacc) in the wood matrix by thermochemical reactions. However, the obtained EMC reduction after HT can be partly reversible, depending on the ability of the wood matrix polymers to fully mechanically relax during HT. We discuss the results of our earlier experimental study on the OHacc content and the associated EMC decrease at 93% RH by a relaxation inhibiting dry-HT vs. a relaxation enabling wet-HT. New experimental results, showing that OHacc does not significantly change during reversible EMC changes, are added to the discussion. This study quantitatively supports a molecular explanation of the reversible EMC, in which wood moisture is principally bound at sorption sites, composed of two functional groups, constituting a hydrogen-donor/acceptor pair, involving at least one OHacc group. The irreversible part of EMC reduction is assigned to the thermochemical removal of OHacc from the wood matrix. The reversible part is attributed to a process of wood polymer conformal rearrangements, bringing an isolated OHacc group in proximity of another free hydrogen-bonding functional group, creating a site for water sorption.

Background

Gongronema latifolium Benth. (family Apocynaceae) leaves (GL) has interesting medicinal properties. The effects of extracts from G. latifolium on blood pressure (BP) and the possible mechanisms of action were also investigated.

Methods

The ultrahigh resolution liquid chromatography orbitrap MS analysis was used to identify the phytochemicals present. Normotensive Wistar rats were anesthetized with sodium pentobarbitone (40 mg/kg) intraperitoneally, and the jugular vein was cannulated for infusion of drugs while the carotid artery was cannulated for direct BP measurement. GL extract (5–20 mg) alone or with nifedipine (10 mg/kg), atropine (2 mg/kg), L-NAME (5 mg/kg), methyl blue (3 mg/kg) and propranolol (1 mg/kg) were administered intravenously to Wistar rats and direct BP measurements were carried out.

Results

Systolic and diastolic BP levels (128/90 mm Hg; MAP 103 ± 3 mm Hg) and heart rates were all significantly (p < 0.01) decreased after GL administration. Raised mean arterial pressure (MAP) and heart rate by atropine, L-NAME and methyl blue were significantly (p < 0.01) reduced after GL administration, while propranolol significantly (p < 0.01) inhibited hypotension caused by GL. Infusion of GL reduced MAP (95 ± 3 mm Hg) comparable with nifedipine (93 ± 2 mm Hg), a calcium channel blocker. The phytochemicals identified were 34 compounds, including oleanolic acid derivatives, flavonoids, antioxidant fatty acids, 2 coumarins and 2 iridoids.

Conclusions

These results suggest that G. latifolium has hypotensive properties mediated by the synergistic activity of the compounds, probably via the β-adrenergic blockade mechanism.
Inverse problems for a class of linear Sobolev type equations with overdetermination on the kernel of operator at the derivative

Published: August 2019

The purpose of this work is to obtain sufficient conditions of a solution existence and uniqueness for a class of inverse problems for linear evolution equations with a degenerate operator at the derivative and with an unknown element in the right-hand side of the equation, which depends on the time variable. The overdetermination condition is given on the kernel of the operator at the derivative, the initial condition have the Cauchy form or the Showalter–Sidorov form.
The obtained abstract results are applied to the investigation of linear inverse problems for the Sobolev system of equations and for the linearized Oskolkov system with overdetermination on the pressure gradient function.

The assumption that short-PIP is hard was challenged by Campbell, Groves and Shepherd.
They proposed an approach for solving short-PIP that proceeds in two steps: first they sketched a quantum algorithm for finding an arbitrary generator (not necessarily short) of the input principal ideal.
Then they suggested that it is feasible to compute a short generator efficiently from the generator in step 1.
Cramer et al.
validated step 2 of the approach by giving a detailed analysis.
In this paper, we focus on step 1, and we show that step 1 can run in quantum polynomial time if we use an algorithm for the continuous hidden subgroup problem (HSP) due to Eisenträger et al.

During a systematic survey of the small mammals in the relatively unexplored north-western regions of the Tibetan plateau in India, we captured and identified the desert hamster Phodopus roborovskii using molecular phylogenetic methods. We also provide revised distributional estimates for this species using niche modelling (Maxent and 19 bioclimatic variables), taking into account sampling bias. We evaluated suitable habitats for the species, identifying regions in the Trans-Himalayas that may harbour this species. This study improves the knowledge of the desert hamster’s range and is a new record and an addition to the Indian sub-continental mammalian fauna, ~750 km southward extension from its known range.
