Published: December 2019

Background

Long-term rotary tillage has led to the deterioration of cotton production in northern China. This deterioration is due to the disturbance of topsoil, a dense plough pan at the 20–50 cm depth, and the decreased water storage capacity. A 2-yr field experiment was performed from 2014 to 2015 to explore a feasible soil tillage approach to halting the deterioration. The experiment consisted of four treatments: replacing the topsoil from the 0–15 cm layer with the subsoil from the 15–30 cm layer (T1); replacing the topsoil from the 0–20 cm layer with the subsoil from the 20–40 cm layer and subsoiling at the 40–55 cm layer (T2); replacing the topsoil from the 0–20 cm layer with the subsoil from the 20–40 cm layer and subsoiling at the 40–70 cm layer (T3); and conventional surface rotary tillage within 15 cm as the control (CK).

Results

The results indicated that the soil bulk densities at the 20–40 cm layer in T2 were 0.13 g·cm− 3 and 0.15 g·cm− 3 lower than those obtained from CK in 2014 and 2015, respectively. The total nitrogen (N) and the available phosphorus (P) and potassium (K) contents from the 20–40 cm layer in T2 and T3 were significantly higher than those in CK and T1. The amount of soil water stored in the 0–40 cm layer of T2 at the squaring stage of cotton was 15.3 mm and 13.4 mm greater than that in CK in 2014 and 2015, respectively, when the weather was dry. Compared with CK, T2 increased cotton lint yield by 6.1 and 10.2 percentage points in 2014 and 2015, respectively, which was due to the improved roots within the 20–60 cm layer, the greater number of bolls per plant and the higher boll weight in the T2 treatment.

Conclusions

The results suggested that soil replacement plus subsoiling would be a good alternative to current practices in order to break through the bottleneck constraining cotton production in northern China. Replacing the topsoil in the 0–20 cm layer with the soil from the 20–40 cm layer plus subsoiling at the 40–55 cm layer would be the most effective method.

Published: December 2019

Background

We sought to determine whether there was a difference in the posterior condylar offset (PCO), posterior condylar offset ratio (PCOR) and clinical outcomes following total knee arthroplasty (TKA) with anterior referencing (AR) or posterior referencing (PR) systems. We also assessed whether the PCO and PCOR changes, as well as patient factors were related to range of motion (ROM) in each referencing system.

Methods

This retrospective study included 130 consecutive patients (184 knees) with osteoarthritis who underwent primary posterior cruciate ligament (PCL)-substituting fixed-bearing TKA. The difference between preoperative and postoperative PCO and PCOR values were calculated. Clinical outcomes including ROM and Western Ontario and McMaster University (WOMAC) scores were evaluated. Furthermore, multiple linear regression analysis was performed to determine the factors related to postoperative ROM in each referencing system.

Results

The postoperative PCO was greater in the AR group (28.4 mm) than in the PR group (27.4 mm), whereas the PCO was more consistently preserved in the PR group. The mean postoperative ROM after TKA was greater in the AR group (129°) than in the PR group (122°), whereas improvement in WOMAC score did not differ between the two groups. Preoperative ROM was the only factor related to postoperative ROM in both groups.

Conclusions

There was no difference in postoperative PCO in AR and PR group and the PCO was not associated with postoperative ROM. PCO was more consistently preserved after surgery in the PR group. The postoperative PCO and PCOR changes did not affect the postoperative ROM. Furthermore, similar clinical outcomes were achieved in the AR and PR groups.

Trial registration

Retrospectively registered (Trial registration number:06-2010-110).
Comparison of the postoperative analgesic effect for infiltration between the popliteal artery and the capsule of the posterior knee and that of periarticular multimodal drug injection in total knee arthroplasty: retrospective study in the immediate postoperative period
Authors: Jung Dae-Won , Shon Won-Yong , Seo Seung-Suk , Kim Ok-Gul , Lee In-Seung
Published: December 2019

Background

The aim of this study is to compare the postoperative analgesic effect of infiltration between the popliteal artery and the capsule of the knee (IPACK) and the effect of periarticular multimodal drug injection (PMDI) in addition to adductor canal block (ACB) after total knee arthroplasty.

Methods

Among patients who received total knee arthroplasty from June 2017 to December 2017, 50 who underwent ACB with additional IPACK and 50 who received ACB with additional PMDI were selected for this study. We compared the postoperative pain numerical rating scale (NRS), the number of times patient-controlled analgesia was administered and the amount administered, the total amount of opioids given, and complications associated with the procedure between the two groups.

Results

NRS measured at rest and 45° knee flexion at days 1 and 2 after surgery was significantly lower in the IPACK group than in the PMDI group. The resting NRS measured at day 3 after surgery was also significantly lower in the IPACK group than in the PMDI group, and the NRS at 45° knee flexion measured from day 3 to day 5 showed a significant reduction in the IPACK group. No complications relating to the procedure occurred.

Conclusions

IPACK may be a better option than PMDI for controlling acute phase pain in patients undergoing total knee arthroplasty.
Lactalbumin, Not Collagen, Augments Muscle Protein Synthesis with Aerobic Exercise
Authors: OIKAWA SARA Y. , MACINNIS MARTIN J. , TRIPP THOMAS R. , MCGLORY CHRIS , BAKER STEVEN K. , PHILLIPS STUART M.
Published: December 2019

Introduction

Protein ingestion and the ensuing hyperaminoacidemia stimulates skeletal muscle protein synthesis in the postexercise period. This response facilitates muscle remodeling, which is important during intensified training. The aim of this study was to determine whether supplementation with α-lactalbumin (LA), with high leucine and tryptophan contents, would improve responses to short periods of intensified aerobic training compared with supplementation with an isonitrogenous quantity of collagen peptides (CP).

Methods

Endurance-trained participants (5 male, 6 female, 24 ± 4 yr, V˙O2 = 53.2 ± 9.1 mL·kg−1·min−1, peak power output = 320 ± 48 W; means ± SD) consumed a controlled diet (1.0 g·kg−1·d−1 protein) and refrained from habitual training for 11 d while taking part in this double-blind randomized, crossover trial. The two intervention phases, which consisted of brief intensified training (4 × 4-min cycling intervals at 70% of peak power output on 3 consecutive days) combined with the ingestion of LA or CP supplements after exercise (20 g) and before sleep (40 g), were separated by 4 d of washout without protein supplementation (i.e., the control phase). In response to each phase, myofibrillar (MyoPS), sarcoplasmic protein synthesis (SarcPS) rates (via 2H2O ingestion) and parameters of sleep quality were measured.

Results

LA ingestion increased plasma leucine (P < 0.001) and tryptophan concentrations (P < 0.001) relative to CP. Intensified training increased MyoPS and SarcPS above the washout phase in LA- and CP-supplemented phases (P < 0.01), with increases being 13% ± 5% and 5% ± 7% greater with LA than CP for MyoPS (P < 0.01) and SarcPS, respectively (P < 0.01).

Conclusions

Despite an isonitrogenous diet, protein synthesis was enhanced to a greater extent when trained participants consumed LA compared with CP during intensified aerobic training, suggesting that protein quality is an important consideration for endurance-trained athletes aiming to augment adaption to exercise training.
Optimal Taxation with Behavioral Agents
Authors: Farhi Emmanuel , Gabaix Xavier
Published: December 2019

This paper develops a theory of optimal taxation with behavioral agents. We use a general framework that encompasses a wide range of biases such as misperceptions and internalities. We revisit the three pillars of optimal taxation: Ramsey (linear commodity taxation to raise revenues and redistribute), Pigou (linear commodity taxation to correct externalities), and Mirrlees (nonlinear income taxation). We show how the canonical optimal tax formulas are modified and lead to novel economic insights. We also show how to incorporate nudges in the optimal taxation framework, and jointly characterize optimal taxes and nudges. (JEL D62, D91, H21)
Using synthetic datasets to bridge the gap between the promise and reality of basing health-related decisions on common single nucleotide polymorphisms
Authors: Wood Thomas R. , Owens Nathan
Published: December 2019

Background: While the academic genetic literature has clearly shown that common genetic single nucleotide polymorphisms (SNPs), and even large polygenic SNP risk scores, cannot reliably be used to determine risk of disease or to personalize interventions, a significant industry of companies providing SNP-based recommendations still exists. Healthcare practitioners must therefore be able to navigate between the promise and reality of these tools, including being able to interpret the literature that is associated with a given risk or suggested intervention. One significant hurdle to this process is the fact that most population studies of common SNPs only provide average (+/- error) phenotypic or risk descriptions for a given genotype, which hides the true heterogeneity of the population and reduces the ability of an individual to determine how they themselves or their patients might truly be affected.

Methods: We generated synthetic datasets generated from descriptive phenotypic data published on common SNPs associated with obesity, elevated fasting blood glucose, and methylation status. Using simple statistical theory and full graphical representation of the generated data, we developed a method by which anybody can better understand phenotypic heterogeneity in a population, as well as the degree to which common SNPs truly drive disease risk.

Results: Individual risk SNPs had a <10% likelihood of effecting the associated phenotype (bodyweight, fasting glucose, or homocysteine levels). Example polygenic risk scores including the SNPs most associated with obesity and type 2 diabetes only explained 2% and 5% of the final phenotype, respectively.

Conclusions: The data suggest that most disease risk is dominated by the effect of the modern environment, providing further evidence to support the pursuit of lifestyle-based interventions that are likely to be beneficial regardless of genetics.
Petra – Holy City from the Perspective of Art, Architecture, inscriptions and Other Features
Authors: Almasri Eyad , Alawneh Firas
Published: December 2019

Scholars who have written about the city of Petra have concentrated on the history and archaeology of the city. And, while some of them have written about Nabataean religion, only few of them mentioned information about the holiness of the city; specifically, if it was worshiped as a deity. The aim of this study is to fulfil a gap in Nabataean religion in general and, in particular, re-examine the status of Petra in their religion. In addition to the archaeological evidence, such as buildings, art, and features, the study is based on written resources, such as historical sources and Nabataean inscriptions found in Petra and other cities.

Kinetic, Thermodynamic and Isotherm Studies for the removal of Acid Red 88 from Aqueous Medium by Polyaniline-CuCl2 Composite
Authors: Dhanagopal Anusha , Dheenathayalan Lingeswari , Thiyagarajan Vimala
Published: December 2019

The metal salt doped polyaniline has been used as adsorbent for the removal of synthetic dye. The influence of experimental parameters like association time, adsorbent dosage, agitating speed, pH and electrical conductivity on adsorption of Acid Red 88 was systematically investigated. More than 95% of Acid Red 88 was removed after 55 minutes of adsorbent/adsorbate contact time for 0.3g/L of PANI-CuCl2. Calculations have been carried out to analyse the impact of weight of PANI-CuCl2 composite and concentration of Acid Red 88 on the percentage of decolourisation. Kinetics and isotherm analysis were also carried out to describe the adsorption process. Electrical conductivity, SEM and FTIR technique were used to characterize the adsorbent before and after adsorption. The thermodynamic parameters like changes in free energy, enthalpy and entropy were also evolved to predict the nature of adsorption. The adsorbent is stable, easy to prepare and suitable to remove Acid Red 88 from effluent.
The impact of a patient’s engagement in their health on the magnitude of limitations and experience following upper limb fractures
Authors: Jayakumar Prakash , Teunis Teun , Vranceanu Ana Maria , Williams Mark , Lamb Sarah , Ring David , Gwilym Stephen
Published: December 2019

Aims

Patient engagement in adaptive health behaviours and interactions with their healthcare ecosystem can be measured using self-reported instruments, such as the Patient Activation Measure (PAM-13) and the Effective Consumer Scale (ECS-17). Few studies have investigated the influence of patient engagement on limitations (patient-reported outcome measures (PROMs)) and patient-reported experience measures (PREMs). First, we assessed whether patient engagement (PAM-13, ECS-17) within two to four weeks of an upper limb fracture was associated with limitations (the Quick Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH), and Patient-Reported Outcome Measurement Information System Upper Extremity Physical Function computer adaptive test (PROMIS UE PF) scores) measured six to nine months after fracture, accounting for demographic, clinical, and psychosocial factors. Secondly, we assessed the association between patient engagement and experience (numerical rating scale for satisfaction with care (NRS-C) and satisfaction with services (NRS-S) six to nine months after fracture.

Methods

A total of 744 adults with an isolated fracture of the proximal humerus, elbow, or distal radius completed PROMs. Due to multicollinearity of patient engagement and psychosocial variables, we generated a single variable combining measures of engagement and psychosocial factors using factor analysis. We then performed multivariable analysis with p < 0.10 on bivariate analysis.

Results

Patient engagement and psychosocial factors combined to form a single factor (factor 1) accounting for 20% (QuickDASH, semi-partial R2 = 0.20) and 14% (PROMIS UE PF, semi-partial R2 = 0.14) of the variation in limitations six to nine months after fracture. Factor 1 also accounted for 17% (NRS-C, semi-partial R2 = 0.17) of variation in satisfaction with care, and 21% (NRS-S, semi-partial R2 = 0.21) of variation in satisfaction with services. Demographic factors (age, sex, work status) and measures of greater pathophysiology (type of fracture, high-energy injury, post-surgical complications), accounted for much less variation.

Conclusion

Patients who actively manage their health and demonstrate effective emotional and social functioning share a common underlying trait. They have fewer limitations and greater satisfaction with care during recovery from upper limb fractures. Future efforts should focus on evaluating initiatives that optimize patient engagement, such as patient education, coaching, and a communication strategy for healthcare professionals.

Polyethylene manufacturing characteristics have a major effect on the risk of revision surgery in cementless and hybrid total hip arthroplasties
Authors: Davis Edward T. , Pagkalos Joseph , Kopjar Branko
Published: December 2019

Aims

The aim of this study was to identify the effect of the manufacturing characteristics of polyethylene acetabular liners on the survival of cementless and hybrid total hip arthroplasty (THA).

Methods

Prospective cohort study using linked National Joint Registry (NJR) and manufacturer data. The primary endpoint was revision for aseptic loosening. Cox proportional hazard regression was the primary analytical approach. Manufacturing variables included resin type, crosslinking radiation dose, terminal sterilization method, terminal sterilization radiation dose, stabilization treatment, total radiation dose, packaging, and face asymmetry. Total radiation dose was further divided into G1 (no radiation), G2 (> 0 Mrad to < 5 Mrad), G3 (≥ 5 Mrad to < 10 Mrad), and G4 (≥ 10 Mrad).

Results

A total of 5,329 THAs were revised, 1,290 of which were due to aseptic loosening. Total radiation dose, face asymmetry, and stabilization treatments were found to significantly affect implant survival. G1 had the highest revision risk for any reason and for aseptic loosening and G3 and G4 the lowest. Compared with G1, the adjusted hazard ratio for G2 was 0.74 (95% confidence interval (CI) 0.64 to 0.86), G3 was 0.36 (95% CI 0.30 to 0.43), and G4 was 0.38 (95% CI 0.31 to 0.47). The cumulative incidence of revision for aseptic loosening at 12 years was 0.52 and 0.54 per 100 THAs for G3 and G4, respectively, compared with 1.95 per 100 THAs in G1. Asymmetrical liners had a lower revision risk due to aseptic loosening and reasons other than aseptic loosening compared with symmetric (flat) liners. In G3 and G4, stabilization with vitamin E and heating above melting point performed best.

Conclusion

Polyethylene liners with a total radiation dose of ≥ 5 Mrad, an asymmetrical liner face, and stabilization with heating above the melting point demonstrate best survival. Cite this article: Bone Joint J 2020;102-B(1):90–101

Contribution to the Knowledge of the Genus Proceratium Roger (Hymenoptera: Formicidae: Proceratiinae) in the New World
Authors: Fernandes Itanna Oliveira , Delabie Jacques Hubert Charles , Fernández Fernando Castiblanco
Published: December 2019

The genus Proceratium Roger comprises rare ants that are irregularly distributed in tropical and temperate regions of the world. Despite this global distribution, these ants are rarely collected, likely due to their cryptobiotic lifestyle. In the New World, the genus comprises 22 known species distributed from Southern Canada to the South of Brazil, and in some Caribbean islands. The taxonomy of the genus Proceratium is here updated for South America. We describe P. amazonicum sp. nov, from Rondônia state and provide distribution data for P. brasiliense, P. convexipes, and P. silaceum. We also present, for the first time, high-resolution images of the P. colombicum type and P. ecuadoriense, and provide a new record of P. micrommatum from Peru, and comment about its morphological variation and distribution. A key for the workers of the P. micrommatum clade is also provided. The species we describe belongs to P. micrommatum clade and represents the second species recorded from Brazil after 60 years, since only P. brasiliense was known previously in the country.
Morphometric Variability among Populations of Euglossa cordata (Hymenoptera: Apidae: Euglossini) from Different Phytophysiognomies

Published: December 2019

Geometric morphometrics is a tool capable of measuring the response of organisms to different environmental pressures. We tested the hypothesis that E. cordata wing morphometry, as an indicator of response to environmental pressure, it would vary depending on habitat changes, in the Atlantic Forest, Savanna and dry forest (Caatinga). For analysis of wing shape and size, 18 landmarks were digitized at the intersections of the wing veins 348 individuals. Except for the two populations sampled in Chapada Diamantina, the wing shape had significant statistical variations among the populations (p < 0.05). The wing size variation was also statistically significant among populations (p < 0.05).  Although E. cordata is a species tolerant to different environments, the observed morphometric variability may be related to population adaptations to the conditions of each phytophysiognomy.
Music for mothers and babies: A view from alternative theoretical perspectives
Authors: Young Susan
Published: December 2019

This article is based on a recently completed review of mother and baby music programmes that draws mainly on the various written sources associated with those programmes. The review looked primarily at programmes in the United Kingdom with some examples from other English-speaking countries. The review process revealed that the rationales and theories that underpin these programmes are highly psychologized, drawing on a reinvigoration of attachment theory that has become interwoven with recent ideas from neuroscience. It also revealed that the written sources do not acknowledge or reflect upon the wider social, cultural and political context which drives and shapes this rapidly expanding area. Drawing on alternative theoretical perspectives from parenting culture studies, post-feminist theory, sociology, biological anthropology and feminist musicology, I develop a discussion that explores how mother and baby music resides on a powerful blend of mothering ideology and psychological theory. This blend and the practices it has given rise to, reinforce intensive mothering practices that do not ameliorate but rather perpetuate and reinforce gendered, racialized and classed inequalities. Intensive mothering in a neo-liberal society supposedly offers choice, autonomy and fulfilment as a mother, but in reality requires unrealistic levels of investment and self-regulation by the mother that can result in conflicted feelings of guilt and anxiety.

A New Organic Dye Cordia sebestena Sensitized Solar Cell with Current-Voltage Characteristics
Authors: Rekha M. , Kowsalya M.
Published: December 2019

Titanium dioxide nanoparticles have been synthesized by a novel modified sol-gel for the fabrication of natural dye sensitized solar cells. The natural photo sensitizer extracted from Cordia sebestena flower was mixed with the precursor solution. The flower dye has put the effort of a surfactant which has resulted colourized TiO2 instead of white TiO2. Whencompared to the conventional sol-gel method, this modified process has enhanced the properties of TiO2 like, morphology, uniformity in dye
absorption. It has reduced the agglomeration of TiO2 and dye aggregation significantly. The optimized molecular geometry of sebestenoid D, the major pigment of Cordia sebestena and HOMO-LUMO plot are found using density functional theory. The TiO2 nanoparticles were subjected to structural, optical, spectral and morphological studies which showed improved properties in modified sol-gel process. Ecofriendly and low-cost natural dye sensitized solar cells (DSSC) were fabricated using conventional and pre-dye treated TiO2 sensitized by Cordia sebestena flower extract. The I-V studies
showed the solar light photon to electron conversion efficiencies of 0.87 and 1.28 % for sol-gel and modified sol-gel methods, respectively. There has been an enhancement in efficiency by 47 % in modified sol-gel method which is very much promising in terms of efficiency for natural dye sensitized solar cells.

Authors: Tongbram Sujata , Singh S. Dorendrajit , Tongbram Binita , Sharma B. Indrajit
Published: December 2019

In this work, pure SrAl2O4 phosphor is synthesized using precipitation method annealed at 1000 ºC and characterized by XRD, FTIR, UV-visible, Raman, SEM, EDX, TEM, SAED and photoluminescence spectroscopy. The XRD pattern reveals the unit cell structure of SrAl2O4 as monoclinic. The SEM and TEM images show a non-uniform shape with agglomeration, and its size varies from 10 to 80 nm. The SAED pattern confirms polycrystalline and single crystal in the different selected area with different magnification. Photoluminescence emission shows a peak at 467 nm (blue)
when excited at 272 nm wavelength. The electronic structure calculation with the density functional theory (DFT) shows a band gap of 4.4 eV, which is nearly equal to 4.46 eV obtained from the experiment optical absorption spectrum. The findings would be beneficial for furthermore investigations on doping in the pure SrAl2O4 phosphor to enhance its high luminescent intensity and long-lasting for a future technological purpose.

Design and Selection Criteria of Main Parachute for Re entry Space Payload
Authors: Pratap Mahendra , Agrawal Anil Kumar , Kumar Swadesh
Published: December 2019

Parachutes are used as a decelerator in the re-entry, descent, and landing of space recovery payloads, providingstability and desired descent rate for a safe landing. The selection of the main parachute is the most critical andimportant part of the space module recovery system. Parachute size is restricted by the required landing speed,materials, and weight of the payload. Parachute materials are selected based on the various forces experienced bythe parachute. An investigation has been carried out to design a parachute system which gives less impact velocity, less angle of oscillation and less impact load for the landing of a crew module. Therefore, in this paper, selection criteria for the main parachute have been discussed considering recovery of re-entry space payload of 500 kg (unmanned) and 3500 kg (manned) class. Based on analysis carried out on the parachute size, canopy filling time, velocity reduction, peak deceleration, and opening shock, authors have proposed a unique type of solid canopy with slots (slots of the minimum area equivalent to geometry porosity) for the main parachute rather than a complex ringsail or disk-band type canopy. With this new concept, the parachute has been designed, developed and qualified through testing, trials and maiden flight of space capsule in LEO and is propose to use in the next manned space mission program.

Technological advancements in the field of chemical threat have made it possible to create extremely dangerous chemical warfare agents (CWA). Hence, the effective protection of personnel is very important in a chemical warfare scenario amidst the current climate of terrorism awareness. In particular, body protection plays a substantial role in the chemical defence considering the urgency of situation in the nuclear, biological and chemical environment. Activated carbon spheres (ACS) based permeable chemical protective clothing (coverall) was developed for protection against CWA. The adsorbent material i.e, ACS used in this protective clothing provided higher adsorption capacity (1029 mg/g in terms of iodine) and low thermal burden (34 °C WBGT index) compared to earlier indigenously developed NBC suit. This article focuses on the extensive evaluation of chemical protective clothing against sulfur mustard (HD), a CWA. The results revealed that the developed protective clothing provided more than 24 h protection against HD. This chemical protective suit is light weight (< 2.75 kg for XL size). It also has higher air permeability (> 30 cm3/s/cm2) as well as less water vapour resistance (< 9.6 m2Pa/W). With continued innovations in materials and attention to key challenges it is expected that advanced, multifunction chemical protective suit will play a pivotal role in the CWA protection scenario.

Published: December 2019

Antimicrobianos estão entre os medicamentos mais utilizados na atenção primária. Contudo, as prescrições ocorrem de forma não adequada, pondo em risco a segurança do paciente, podendo gerar impactos clínico e econômico. No presente estudo foram avaliadas prescrições de antimicrobianos de todas as unidades básicas de saúde de Caicó, RN, Brasil. Trata-se de estudo retrospectivo, descritivo, exploratório com abordagem quantitativa. Foram analisadas 1046 prescrições de antimicrobianos elaboradas durante o ano de 2016 e arquivadas nas Farmácias das unidades básicas de saúde. Todas as prescrições 1046 (100%) estavam não conformes com a legislação. Os itens não conformes mais frequentes foram: ausência de carimbo e assinatura do farmacêutico atestando dispensação (100%), seguido de sexo (96,5%) e idade do usuário (96,5%), duração do tratamento (40,8%), via de administração (35,7%), informações que permitiam contatar o prescritor (20,1%) e concentração (17,0%). Os antimicrobianos mais prescritos foram penicilinas com espectro estendido 347 (31,5%), macrolídeos 218 (19,8%) e cefalosporinas de primeira geração 185 (16,8%). O estudo mostrou a necessidade de instituir medidas de sensibilização dos prescritores sobre a importância de uma prescrição clara e sem ausência de itens fundamentais para que se possa imprimir segurança no uso do medicamento.

O uso das plantas como fonte medicinal tem grande relevância socioeconômica na qualidade de vida das comunidades de baixa renda, devido sua alta disponibilidade, baixa toxicidade, risco mínimo de efeitos colaterais e, principalmente, aos baixos custos e/ou sem ônus, quando comparados aos medicamentos industrializados. Contudo, estes produtos estão susceptíveis a contaminação desde a coleta até manipulação. Portanto, o presente estudo teve como objetivo avaliar os aspectos legais e a qualidade do produto à base de graviola, obtidos em diferentes farmácias do município de Cuité, PB, Brasil. Os aspectos legais foram avaliados utilizando as resoluções específicas da Agência Nacional de Vigilância Sanitária (Anvisa). A contagem de microrganismos viáveis foi realizada pelo método de contagem em placa em profundidade e a identificação dos patógenos, por semeadura das amostras em meios de cultura seletivos, seguida de confirmação por meio de provas bioquímicas. Foi realizada, ainda, a técnica de microcultivo e análise microscópica para identificação de fungos filamentosos. O produto apresentou não-conformidades do ponto de vista legal. Do ponto de vista microbiológico, as amostras estavam dentro dos limites aceitáveis pela Farmacopeia Brasileira para fungos e bactérias, sendo identificados fungos do gênero Cladosporium spp., e Fonsecae pedrosoi. Assim, há necessidade de uma maior e mais eficiente fiscalização para este tipo de produto, para uma maior garantia de segurança ao paciente.

Для уравнений идеальной газовой динамики в цилиндрической системе координат с произвольным уравнением состояния рассматривается одна двумерная подалгебра из оптимальной системы 11-мерной алгебры Ли операторов дифференцирования первого порядка. Базис операторов рассматриваемой подалгебры состоит из оператора галилеева переноса и оператора движения по спиральным линиям. Инварианты операторов задают представление решения: вид компонент вектора скорости, функции плотности и функции энтропии. После подстановки представления решения в дифференциальные уравнения газовой динамики вводится предположение о линейной зависимости радиальной компоненты скорости от пространственной координаты. Записаны преобразования эквивалентности, которые допускает система уравнений газовой динамики после подстановки представления решения. Для уравнения состояния политропного газа найдены все четыре решения в зависимости от показателя адиабаты. Для каждого случая записаны уравнения мировых линий движения частиц газа. Найден якобиан перехода от эйлеровых переменных к лагранжевым. По значению якобиана определены моменты времени коллапса частиц газа. В результате полученные решения описывают прямолинейный разлет частиц газа с поверхности геликоида. Движения частиц по логарифмическим спиралям, лежащим на параболоиде и движения по гиперболическим спиралям, лежащим на конусе.
Задача Дирихле для уравнения смешанного типа с характеристическим вырождением
Authors: Сабитова Юлия Камилевна , Sabitova Yuliya Kamilevna
Published: December 2019

Для уравнения смешанного эллиптико-гиперболического типа с характеристическим вырождением исследована первая граничная задача в прямоугольной области. Установлен критерий единственности решения задачи. Ранее при доказательстве единственности решений краевых задач для уравнений смешанного типа использовали принцип экстремума или метод интегральных тождеств. Единственность решения данной задачи установлена на основании полноты системы собственных функций соответствующей одномерной спектральной задачи. Решение задачи построено в виде суммы ряда по системе собственных функций. При обосновании сходимости полученного ряда возникает проблема малых знаменателей более сложной структуры, чем в известных работах, относительно параметра, зависящего от длин сторон прямоугольника из гиперболической части области и показателя степени вырождения уравнения.
В связи с этим установлены оценки об отделенности от нуля с соответствующей асимптотикой в случаях, когда данный параметр представляет собой натуральное, рациональное и алгебраическое иррациональное число степени два.
Если данный параметр не является алгебраическим иррациональным числом степени два, то решения задачи в виде суммы ряда не существует. С помощью полученных оценок обоснована равномерная сходимость построенного ряда в классе регулярных решений при некоторых достаточных условиях относительно граничных функций. Также доказана устойчивость решения задачи относительно граничных функций в нормах пространства суммируемых с квадратом функций и в пространстве непрерывных функций.

Проблемы распространения трещин в полосах привлекают внимание в основном из-за их важности для приложений:
вычисление коэффициентов интенсивности напряжений для стандартных тестов, таких как трех- и четырехточечный изгиб; изучение разрушения в тонких слоистых структурах; изучение отслоения покрытий.
Задача о нагружении полосы с центральной трещиной особенно интересна из-за ее относительной простоты, позволяющей анализировать и выделять существенные особенности процессов распространения трещин в структурах подобного типа.
В работе получено точное аналитическое решение для задачи об ортотропной полосе с центральной полубесконечной трещиной, нормально нагруженной самоуравновешенной системой сил. Нагрузки приложены достаточно далеко от вершины трещины, что позволяет рассматривать нагрузку, как приложенную на бесконечности. Общее решение представлено как суперпозиция решений для двух случаев: симметрично приложенными моментами и поперечными силами с компенсирующими их моментами. Цель исследования состоит в нахождении коэффициентов при сингулярностях поля напряжений вблизи вершины трещины, то есть коэффициентов интенсивности напряжений. Решение задачи о раскрытии трещины получено для произвольного значения параметра анизотропии с помощью преобразований Лапласа для уравнений, связывающих усилия, действующие вдоль линии трещины, и производные относительных смещений берегов трещины. Коэффициент интенсивности напряжений для нагружения моментами совпадает с элементарным решением теории пластин. Коэффициент интенсивности напряжений для нагружения силами получен в виде функции одного параметра, выраженного в виде однократного интеграла.
Сравнение с имеющимися численными результатами продемонстрировало хорошее согласование решения в диапазоне параметра анизотропии, для которого были получены численные решения. Полученное решение охватывает все термодинамически допустимые значения параметров анизотропии.
