Desempenho Termoenergético de Edificações Sob a Ótica das Mudanças Climáticas: Uma Revisão Sistemática
Authors: Guarda Emeli Lalesca Aparecida da , Durante Luciane Cleonice , Callejas Ivan Julio Apolonio
Published: April 2020

Este artigo parte da premissa de que as alterações climáticas registradas são consequências do aquecimento global, sendo seus efeitos passíveis de mensuração no ambiente construído. As condições internas de conforto e habitabilidade nas edificações têm sido estudadas com amparo de simulação computacional de cenários futuros, tomando-se por base arquivos climáticos que incorporam os efeitos do aquecimento. O objetivo deste trabalho é elaborar um panorama das publicações científicas acerca das projeções de aumento da temperatura interna e do consumo de energia elétrica em edificações, considerando os parâmetros do Quarto Relatório (AR4) do Painel Intergovernamental sobre Mudanças Climáticas (IPCC). Utilizou-se da metodologia de revisão sistemática para reconhecer os critérios considerados no estabelecimento dos cenários futuros (2020, 2050 e 2080) e a distribuição espacial dos estudos sobre o tema. Os resultados apontam para uma grande variabilidade da demanda de energia, justificada pelas diferenças nos critérios adotados, nas tipologias construtivas e na localização dos edifícios pesquisados. Um recorte para o setor residencial brasileiro, revela que apesar das disparidades entre as demandas previstas nos cenários de aquecimento global, todas as provisões indicam elevação de consumo energético para manutenção da habitabilidade nas zonas bioclimáticas brasileiras, sendo, portanto, indispensável considerar a resiliência das edificações como forma de estratégia de adaptação.

Authors: Faria Albert Willian , Souza Eduardo Matiola , E Silva Rodrigo Alves
Published: April 2020

The present study develops a 3D numerical model of the concrete pavement system of aerodromes in contact with the main landing gear of aircrafts using Finite Element Method (FEM). The pavement system used in the analysis consisted of six concrete slabs overlaying a subgrade medium with stiffness k. Doweled bars are considered for the pavement transverse joints while aggregate interlocks are considered for longitudinal joints. A parametric study was conducted to validate the model numerically, as well as to investigate the influence of the doweled bars, aggregate interlocks and subgrade stiffness on the pavement deflections when it is subjected to a dynamic load. About 77% decrease in deflection was attained due to the presence of doweled bars. This study additionally presents a methodology for designing the pavement thickness and the compressive strength of concrete based upon the Mohr-Coulomb’s failure criterion. It is found that for a pavement thickness of 0.305m the minimum compressive strength of concrete should be 28 MPa.
Twister Generator of Poisson Random Numbers with the Use of Cumulative Frequency Technology
Authors: Deon A.F. , Dmitriev D.D. , Menyaev Yu.A.
Published: April 2020

The widely known generators of Poisson random variables are associated with different modifications of the algorithm based on the convergence in probability of a sequence of uniform random variables to the created stochastic number. However, in some situations, this approach yields different discrete Poisson probability distributions and skipping in the generated numbers. This paper offers a new approach for creating Poisson random variables based on the complete twister generator of uniform random variables, using cumulative frequency technology. The simulation results confirm that probabilistic and frequency distributions of the obtained stochastic numbers completely coincide with the theoretical Poisson distribution. Moreover, combining this new approach with the tuning algorithm of basic twister generation allows for a significant increase in length of the created sequences without using additional RAM of the computer

Published: April 2020

Methods are considered of generating signals in a radar sensor receiver provided with a colocated antenna system of Multiple Input Multiple Output (MIMO) configuration when synthesizing virtual antenna arrays. Review of the basic spectral methods used in beamforming with digital automobile radars, such as Capon method, MUSIC and ESPRIT was carried out. Spatial spectra obtained by various methods were constructed for a radar signal model, and comparative spectra characteristic by angular resolution is provided. Output heatmaps in the angle-distance coordinate were constructed to represent methods operation according to the real target situation based on data sampling from the front-mounted automobile radar. Advantages of decomposition methods based on MUSIC and ESPRIT algorithms in solving the problem of a signal emitter localization are presented
Features of the Heating Process in Ultrasonic Welding of Polycarbonate Products under Independent Pressure
Authors: Volkov S.S. , Remizov A.L. , Pankratov A.S.
Published: April 2020

This paper presents a mechanism of formation of a hard-to-weld polycarbonate joint by ultrasonic welding. The method utilizes internal and external friction occurring in the welded joint area on abutting surfaces due to shear vibrations of the end of the upper part relative to the lower part. A layer of the heated welded material is formed, localized by thickness, in which predominant absorption of the ultrasonic vibrations occurs, which allows one to obtain high-quality and durable welded joints without significant deformation due to the concentration of thermal energy in the welding zone. The effect of independent welding pressure on the strength of the welded joint of polycarbonate is considered. A new method of ultrasonic welding under the conditions of independent pressure is proposed. The method consists of dividing the static welding pressure into two components: the pressure of the acoustic contact in the zone of contact of the waveguide with the product, and the welding pressure that compresses the welded products, with the latter component being lower than the former. In order to obtain high-quality welded joints made of polycarbonate and to prevent displacement of the welded edges during the welding process relative to each other, a special preparation of the welded edges is developed, which allows one part to be moved vertically relative to the other during the welding process. It is established that the quality of welding depends on the speed of movement and the angle of cutting the edges.
Analysis of numerical calculation of elastic-plastic shell collapse with growing instability
Authors: Novoseltsev А.S. , Babkin A.V.
Published: April 2020

The paper presents research of the collapse of the elastic-plastic shell under external surface forces simulating explosive loading by mathematical simulation using numerical methods. The problem was solved in two-dimensional curved geometries as a non-stationary problem of continuum mechanics. We applied the Wilkins Lagrangian method. The instability of the shell was initiated by harmonic surface perturbations on the outer or inner surfaces. The characteristics of the explosive loading were also changed: the maximum pressure, pressure fall time constant, and the time of application of the explosive load. The size of instability was determined by the deviation of the disturbed surface or the boundary of the jet-forming layer from the cylindrical one. We have established the parameters of the shell and the impulse loading on the shell, which affect most strongly the growth of instability during collapse.
On the sensitivity of large precision space structures of high-modulus fibrous polymer composite materials to microdynamical effects
Authors: Sayapin S.N.
Published: April 2020

The paper considers the problem of sensitivity of large precision space structures made of high-modulus fibrous polymer composite materials to external and internal microdynamic effects. This problem is related to the extent of structure forming elements, as well as to an abrupt increase in the elastic modulus of the material when passing the threshold of low stresses. It is found that under low loading in the orbital flight conditions the calculated values of the elastic modulus of large precision space structures made of high-modulus fibrous polymer composite materials may be higher than the real ones by more than 20 times, which must be taken into account in the calculations. Possible ways to reduce the sensitivity of such space structures made of high-modulus fibrous polymer composite materials to external and internal microdynamic effects are shown.

Authors: Gordienko E.S. , Simonov A.V. , Khudorozhkov P.A.
Published: April 2020

The paper discusses the design of a mission for delivering lunar soil to the Earth. The analysis of its main stages is carried out. These stages include possible flight pattern selection, analysis of the flight from the Earth to the circular orbit of the Moon artificial satellite, determination of trajectories of removal from lunar surface into the reference orbit, the search for return paths that depart from the Moon and fall into a given area on the Earth’s surface. A variant of determining the initial approximation for the method of return paths constructing is proposed. It is based on solving a two-parameter boundary value problem in the central field of the Earth. Varying the duration of the flight from the Moon to the Earth and the time of the spacecraft approach to the Earth, pointing return trajectory into vicinity of the polygon P is achieved for a given perigee radius. The article presents the main characteristics of the mission obtained using this technique.

W artykule omówiono wybrane przedstawienia Tadeusza Kościuszki pędzla Michała Stachowicza (1768–1825) – krakowskiego malarza, rysownika i grafika, znanego głównie jako twórcę scen upamiętniających ważne wydarzenia historyczne, w szczególności związane z insurekcją kościuszkowską. Artysta ten stworzył kilkadziesiąt prac (obrazy olejne, gwasze, rysunki) ukazujących postać Naczelnika, powielanych wielokrotnie w różnych ujęciach. Są to zarówno portrety (indywidualne i grupowe), jak i sceny zbiorowe o charakterze historycznym, batalistycznym oraz alegorycznym. Na wszystkich tych kompozycjach Kościuszko jawi się jako wódz, bohater narodowy, obrońca ojczyzny, człowiek niezłomny.
Elżbieta Zawacka (1909–2009) – zasłużony żołnierz i aktywna „feministka”
Authors: Marcinkiewicz-Kaczmarczyk Anna
Published: April 2020

Elżbieta Zawacka, już w okresie przedwojennym, poświęciła się zarówno działalności wojskowej, jak i pedagogicznej, czynnie angażując się w działalność Przysposobienia Wojskowego Kobiet i pełniąc m.in. funkcję Komendantki PWK Rejonu Śląskiego. W ramach tej działalności m.in. organizowała i prowadziła szkolenia dla młodzieży. Po ataku wojsk niemieckich czynnie uczestniczyła w kampanii wrześniowej, a następnie wstąpiła do armii podziemnej, podejmując służbę najpierw w łączności, a potem kurierską. W ramach tej ostatniej przewiozła pocztę do Sztabu Naczelnego Wodza w Londynie, gdzie również prowadziła rozmowy na temat łączności oraz uregulowania prawnego służby wojskowej kobiet. Z Londynu powróciła na ziemie polskie, wykonując skok spadochronowy z cichociemnymi, a następnie uczestniczyła w powstaniu warszawskim. Po zakończeniu wojny poświęciła się pracy naukowej i pedagogicznej. Jedną z jej zasług w okresie powojennym było utworzenie Fundacji Generał Elżbiety Zawackiej, Archiwum i Muzeum Pomorskiego Armii Krajowej oraz Wojskowej Służby Polek.

Za swoje zasługi w działalności militarnej, a także na polu naukowym, pedagogicznym i społecznym E. Zawacka otrzymała nagrody i wyróżnienia. Jeszcze w okresie wojny została odznaczona m.in. Krzyżem Walecznych, Krzyżem Zasługi i Krzyżem Armii Krajowej, a po wojnie, w 2006 r. otrzymała stopień generała brygady. Oprócz tego w 1995 r. odznaczono ją Orderem Orła Białego, a w 2002 r. Prezes IPN nadał jej tytuł Kustosza Pamięci Narodowej.

Przez całe swoje życie E. Zawacka łączyła pracę militarną, społeczną i pedagogiczną. Jej postawa świadczyła o tym, że umiała walczyć o swoje prawa, nie rezygnowała z obranego celu i niezależnie od okoliczności kontynuowała karierę zawodową. W tym kontekście można ją nazwać zarówno zasłużonym żołnierzem, jak i „feministką”.
Przywracanie i utrwalanie pamięci w społeczeństwie polskim o żołnierzach formacji granicznych Drugiej Rzeczypospolitej poległych w walkach obronnych z niemieckimi i sowieckimi wojskami we wrześniu 1939 roku
Authors: Łach Halina
Published: April 2020

Artykuł prezentuje refleksję nad potrzebą utrwalania pamięci społecznej o żołnierzach formacji granicznych Drugiej Rzeczypospolitej, którzy podczas kampanii polskiej w 1939 r. toczyli bohaterską walkę z wojskami niemieckimi i sowieckimi. Żołnierze oddziałów Korpusu Ochrony Pogranicza (KOP) i Straży Granicznej (SG), wchodząc do związków taktycznych, walczyli w obronie Wielunia, Helu, Węgierskiej Górki, Szacka i Wytyczna. Po wojnie historia wydarzeń z Września i pamięć o żołnierzach KOP i SG była ukrywana. Ważne fakty dotyczące zmagań i bojów żołnierzy zostały wyparte ze zbiorowej świadomości Polaków czy też celowo były pomijane. Dopiero po 1989 r., w nowej rzeczywistości polityczno-gospodarczej pojawiło się w społeczeństwie zainteresowanie pamięcią o żołnierzach KOP i SG, którzy w wojnie obronnej zginęli bądź przeżyli gehennę obozów jenieckich. Głównym celem poszukiwań badawczych było ukazanie miejsc walk obronnych żołnierzy formacji granicznych we wrześniu 1939 r. oraz przedstawienie w czasach obecnych działań jednostek samorządu, organizacji społecznych i organów Straży Granicznej Rzeczypospolitej Polskiej w przywracaniu i utrwalaniu pamięci w społeczeństwie polskim. Rozważania w artykule konkretyzują się na postawionej tezie, która brzmi: Utrwalanie i upamiętnianie w społeczeństwie polskim miejsc walk żołnierzy formacji granicznych we wrześniu 1939 r. stanowią trwałe wartości dla dziedzictwa narodu i państwa polskiego, które należy popularyzować w procesie wychowania i kształcenia w szczególności młodego pokolenia.
HIV Prevention Programming for Older African American Women: The Impact of a Faith-Based and Behavioral Science Partnership on Depressive Symptoms
Authors: Ebor Megan T. , Jackson Aurora P.
Published: April 2020

Objective: The current study sought to test the effect of an HIV prevention interven­tion on depressive symptoms in a sample of older African American women.Design, Setting and Participants: A pretest-posttest randomized control group design was conducted in a mega-church in Los Angeles with a sample of 62 older African American women, aged ≥50 years, 29 of whom were randomly assigned to the experimental condition and 33 to the comparison/control condition.Measures: A measure of psychological wellbeing (CES-D) was utilized to test the effect of the four-session group interven­tion vs the one-session informational group intervention on change in depressive symp­toms from pretest to posttest. Demographic characteristics included: measures of age in years; relationship and employment statuses (coded 1 for yes, 0 for no); and educational attainment.Results: Participation in the study was as­sociated with a significant improvement in the women’s psychological wellbeing from baseline to time 2; ie, decreased depres­sive symptoms. This change was greater for women in the four-session experimental group than for those in the one-session comparison group, due in part to a margin­ally significant interaction between time and experimental conditions.Conclusions: This study demonstrates the utility of faith-based/behavioral-scientist partnerships in HIV programming. Findings contribute to the evidence on interventions that might reduce depressive symptoms and HIV risk among older African American women. Ethn Dis. 2020;30(2):287-294; doi:10.18865/ed.30.2.287
An Examination of Factors Deterring the Pursuit of Advanced Degrees Among Alumni of a Minority Research and Training Program
Authors: Schneider Burton Gretchen , Vicente Maria da Graça H.
Published: April 2020

Minority research and training (MRT) programs utilize interventions aimed at increasing student persistence toward the completion of undergraduate degrees and continuation into doctoral degrees. Numerous studies identify these support interventions as essential components for positive outcomes among underrepresented students, including research experiences, social integration, mentorship, and financial support. Many of these previous studies utilize quantitative design involving current program participants or program alumni who continued into graduate programs. This pilot study employed a multiple case study with a narrative approach involving partici­pants of an MRT program who completed a BSc degree but did not subsequently ma­triculate into a doctoral program. The cross-case analysis identified perceived barriers deterring continuation into doctoral degree programs among former MRT participants. Results from this study add student voice to the current literature and provide recom­mendations to better serve underrepresent­ed students in the STEM disciplines.

Perspective: Black Resilience - Broadening the Narrative and the Science on Cardiovascular Health and Disease Disparities
Authors: Taylor Herman A. , Washington-Plaskett Tulani , Quyyumi Arshed A.
Published: April 2020

The health of African Americans has been largely described in terms of deficits, disease and death. Little attention has been histori­cally given to the fact that African Americans as a population show the sustained ability to survive an evolving array of social, eco­nomic and environmental adversities that date back to more than a century before the founding of the United States. While these inequities have indeed taken (and continue to take) a devastating toll, there is also wide heterogeneity in outcomes, suggesting the existence of substantial individual and col­lective resilience among African Americans.This Perspective aims to stimulate discus­sion and research that explores resilience in a population in which “overcoming” and “bouncing back” from adversities (ranging from minor incidents to legally ordained, chronic and horrific oppression) has been a requirement for survival. Rigorous scientific exploration of Black resilience may yield important insights into the phenomenon of human resilience that transcend race. Ethn Dis. 2020;30(2):365-368; doi:10.18865/ ed.30.2.365

Agresivno vedenje v procesu dolgotrajne rehabilitacije po pridobljeni možganski poškodbi: pregled izkušenj iz prakse
Authors: Šemrov Maša
Published: April 2020

Agresivno vedenje posameznika s pridobljeno možgansko poškodbo (PMP) pogosto ovira pri uspešnem vračanju v okolje, pri čemer se vzroki za pojavljanje in oblike agresivnega vedenja med posamezniki s PMP razlikujejo. V prispevku predstavljamo tiste posledice PMP, za katere v procesu dolgotrajne rehabilitacije opažamo, da se povezujejo s pojavljanjem agresivnega vedenja in ovirajo njegovo obravnavo. Izpostavljamo predvsem težave z inhibicijo odziva, zmanjšanim uvidom, sprejemanjem lastnega stanja in z njim povezanimi čustvenimi težavami ter osebnostne in vedenjske spremembe. Pri obravnavi agresivnega vedenja v procesu dolgotrajne rehabilitacije uporabljamo individualno prilagojen pristop, ki nudi podporo in posamezniku s PMP omogoča razvijanje bolj učinkovitih načinov spoprijemanja z lastnimi zmanjšanimi zmožnostmi. Napredki so omejeni na konkretne situacije, zato ni verjetno, da se agresivno vedenje ne bi več pojavljalo. Kljub temu pa poznavanje problematike lahko pripomore k zmanjševanju tako pojavnosti agresivnega vedenja kot tudi vpliva na življenje posameznika s PMP.

Published: April 2020

Aim: In this work, seven strains of Starmerella bacillaris were analysed for their ability to release polysaccharides during alcoholic fermentation (AF), both in single-strain and in sequential AF together with Saccharomyces cerevisiae.Methods and Results: A synthetic polysaccharide-free must was used to characterise the mannoproteins (MPs) released. The MPs were quantified, characterised in terms of carbohydrate composition, and tested to assess their ability to reduce protein and tartrate instabilities and their ability to affect the foaming properties of wine.Conclusions: All the tested strains in sequential AF increased the total MPs production. Moreover, the strains affected the MPs properties in different ways regarding tartaric and protein stabilities. The MPs released in sequential AF by some S. bacillaris strains showed a significant effect on protein stabilisation and tartaric stability. An effect on the foamability was found for MPs obtained in single-strain AFs of S. bacillaris.Significance and impact of the study: An improvement in wine stability can be achieved using the sequential AF.
Gravity as An Explanation of Spin Measurement in Quantum Entanglement: Possible Timeless State of the Universe
Authors: Farag Ali Ahmed
Published: April 2020

We investigate the matching point between non-inertial frames and local inertial frames. This localization of gravity lead to an emergence of a timeless state of the universe in a mathematically consistent way. I find a geometric interpretation of the speed of light and mass. I find also a relation between every mass measured and the black hole entropy which introduces an information-matter equation from gravity. The experimental evidence of the timeless state of the universe is the quantum entanglement. Since the spin measurement is the manifestation of quantum entanglement measurement. Therefore, the spin of quantum particle can be understood as a relative gravitational red-shift. Therefore the spin quantum number is understood as a quantum gravity measurement in local inertial frames. We introduce also guidance that leads to the least computations of gravitational measurement which is achieved when the ratio equal to the difference.
Inducing Angiogenesis, A Key Step in Cancer Vascularization, and Treatment Approaches
Authors: Saman Harman , Raza Syed Shadab , Uddin Shahab , Rasul Kakil
Published: April 2020

Angiogenesis is a term that describes the formation of new blood and lymphatic vessels from a pre-existing vasculature. This allows tumour cells to acquire sustenance in the form of nutrients and oxygen and the ability to evacuate metabolic waste. As one of the hallmarks of cancer, angiogenesis has been studied extensively in animal and human models to enable better understanding of cancer biology and the development of new anti-cancer treatments. Angiogenesis plays a crucial role in the process of tumour genesis, because solid tumour need a blood supply if they are to grow beyond a few millimeters in size. On the other hand, there is growing evidence that some solid tumour exploit existing normal blood supply and do not require a new vessel formation to grow and to undergo metastasis. This review of the literature will present the current understanding of this intricate process and the latest advances in the use of angiogenesis-targeting therapies in the fight against cancer.
Can Compact Optimisation Algorithms Be Structurally Biased?
Authors: Kononova Anna V. , Caraffini Fabio , Wang Hao , Bäck Thomas
Published: April 2020

In the field of stochastic optimisation, the so-called structural bias constitutes an undesired behaviour of an algorithm that is unable to explore the search space to a uniform extent. In this paper, we investigate whether algorithms from a subclass of estimation of distribution algorithms, the compact algorithms, exhibit structural bias. Our approach, justified in our earlier publications, is based on conducting experiments on a test function whose values are uniformly distributed in its domain. For the experiment, 81 combinations of compact algorithms and strategies of dealing with infeasible solutions have been selected as test cases. We have applied two approaches for determining the presence and severity of structural bias, namely a visual and a statistical (Anderson-Darling) tests. Our results suggest that compact algorithms are more immune to structural bias than their counterparts maintaining explicit populations. Both tests indicate that strong structural bias is found only in one of the algorithms (cBFO) regardless of the choice of strategy of dealing with infeasible solutions and cPSO mirror. For other test cases, statistical and visual tests disagree on some cases classified as having mild or strong structural bias: the former one tends to make harsher decisions, thus needing further investigation.

In the present work, the state of the art of the most common additive manufacturing (AM) technologies used for the manufacturing of complex shape structures of graphene-based ceramic nanocomposites, ceramic and graphene-based parts is explained. A brief overview of the AM processes for ceramic, which are grouped by the type of feedstock used in each technology, is presented. The main technical factors that affect the quality of the final product were reviewed. The AM processes used for 3D printing of graphene-based materials are described in more detail; moreover, some studies in a wide range of applications related to these AM techniques are cited. Furthermore, different feedstock formulations and their corresponding rheological behaviour were explained. Additionally, the most important works about the fabrication of composites using graphene-based ceramic pastes by Direct Ink Writing (DIW) are disclosed in detail and illustrated with representative examples. Various examples of the most relevant approaches for the manufacturing of graphene-based ceramic nanocomposites by DIW are provided.
Open Obturator Hip Dislocation
Authors: Medda Suman , Araiza Edgar T. , Pilson Holly T.
Published: April 2020

Case:

An open obturator dislocation with associated pelvic ring injury and perineal wound underwent fixation and aggressive debridement. Despite this, the patient proceeded to infection requiring additional debridements and prolonged intravenous antibiotics. At 18 months postinjury, the patient developed avascular necrosis and significant heterotopic ossification; however, she was able to ambulate.

Conclusions:

Open obturator dislocations of the hip require a multidisciplinary team. Despite prompt antibiotic therapy and aggressive debridement, patients are at high risk of infection because of the microbial environment in this region. Open obturator hip dislocations are at significant risk of avascular necrosis despite timely reduction.

Published: April 2020

Background: Study older adults’ quality of life is becoming increasingly important in the assessment, quality improvement and allocation of health and social care service. The purpose of this study was to enhance knowledge on the relationship between modifiable (psychological variables) and non-modifiable variables (sociodemographic), and quality of life in elderly, regarding psychological and social variables in Portuguese context.Methods: This is a cross-sectional study, including 604 older adults from general community. 63.6% of the sample was composed by female gender with a mean age of 71.6(SD=4.81). Participants completed the following instruments: Barthel Index to assess functionality; Satisfaction with Social Support Scale to assess social support; The Spiritual and Religious Attitudes in Dealing with Illness to assess spirituality and Short Form Health Survey 36, to assess mental and physical quality of life.Results: A path analysis model was performed where the presence of a chronic disease, age and functionality has a direct effect on physical quality of life and spirituality had a direct effect on mental quality of life. Social support mediated the relationship between functionality and mental quality of life, and in turn, functionality mediated the relationship between age and physical quality of life.Conclusions: Results reinforce the effect of age and chronic disease as non-modifiable variables as well as functionality, spirituality and satisfaction with social support as modifiable variables, in the quality of life of older people. Social support, health and education programs in the community should be promoted in order to improve quality of life in this population. Strategies to promote functionality and enhance the social support network, especially in the elder with chronic illness, should be a priority.

Background: A few previous studies have investigated patient satisfaction following total hip arthroplasty (THA) according to the degree of pelvic deformity. This study compared patient-reported outcomes following primary THA for Crowe types Ⅲ, Ⅳ and I dysplasia.Methods: This was the retrospective case-control study assessed patients who underwent primary THA by a single surgeon at a single institution from 2008 to 2016. We sent postal questionnaires to 38 patients with Crowe type III and IV dysplasia. Among the questionnaire respondents, 23 patients, excluding cases with a follow-up period of less than 1 year, were enrolled as the H group. The control group included 46 patients with Crowe type I, matched for sex, age, body mass index and surgical approach. To investigate the influence of femoral shortening osteotomy, the H group was divided according to whether or not femoral shortening osteotomy was performed. Ten patients underwent THA with femoral shortening osteotomy (FO group), while 12 patients underwent THA without femoral shortening osteotomy (N-FO group). Patient demographics, average follow-up period, surgical information, pre- and postoperative leg length discrepancy (LLD), and perioperative complications were investigated. Clinical evaluations were performed using the Japanese Orthopaedic Association (JOA) scores, 36-item short-form survey (SF-36), net promotor score (NPS), visual analogue scale (VAS), and questionnaires. The VAS and SF-36 was acquired at only final follow-up. Results: The H and control groups were not significantly different in the postoperative JOA scores and SF-36. In the H group, VAS at the final follow-up was significantly higher, and significantly more patients felt that postoperative rehabilitation was serious, expressing that they underwent THA for LLD correction. Additionally, VAS in the FO group was higher than those in the N-FO group. Postoperative LLD was significantly greater in the H group than in the control group. Each group had the NPS of over 50.Conclusion: The postoperative VAS was higher in Crowe type Ⅲ and Ⅳ dysplasia than in Crowe type I dysplasia, but there were no significant differences in the postoperative satisfaction, JOA score and SF-36. The findings may help explain the effects of THA preoperatively to patients with Crowe type Ⅲ and Ⅳ dysplasia.Level of Evidence: Therapeutic Level 3b

Published: April 2020

Background:The aim of this study was to examine the relationship between psychological characteristics and physical activity levels, measured as the average number of steps per day, in people with knee osteoarthritis (OA).Methods: This study analysed baseline data from a randomized controlled trial (Australian New Zealand Clinical Trials Registry reference: ACTRN12612000308897). A total of 167 adults aged over 50 years, with knee pain rated as four or more on an 11-point numeric rating scale, and knee OA diagnosed using American College of Rheumatology clinical criteria, were recruited from the community (62 men and 105 women; mean age, 62.2 ± 7.5 years). The average number of steps per day over seven consecutive days was measured using an accelerometer-based device. Psychological characteristics evaluated were: depressive symptoms (Depression Anxiety Stress Scale), self-efficacy (Arthritis Self-Efficacy Scale for pain and other symptoms), fear of movement (Brief Fear of Movement Scale for Osteoarthritis), and pain catastrophizing (Pain Catastrophizing Scale). The association between the average number of steps per day and psychological characteristics was analyzed using a multiple linear regression analysis, with the average number of steps per day as the dependent variable, adjusting for each psychological characteristic separately, and age, sex, body mass index, and pain entered as covariates.Results: There was evidence that the amount of physical activity was associated with fear of movement (coefficient [B]: -117, 95% confidence interval [95%CI]: -227 to -8) and with pain catastrophizing (B: -44, 95%CI: -86 to -1). The association with self-efficacy was similar (B:117, 95%CI: -12 to 246). However, the direction of the association with depressive symptoms was less clear (B: -59, 95%CI: -138 to 19).Conclusions: The results of this study revealed that the relationship was such that lower fear of movement and lower pain catastrophizing may be associated with more steps per day. It may be hypothesized that fear of moving and pain catastrophizing lead to activity avoidance and that strategies to improve these disease-related psychological aspects may be useful in enhancing physical activity participation, although this hypothesis is highly speculative and needs further testing given the cross-sectional design of this study.

Published: April 2020

Background: Consensus on tibial rotation in total knee arthroplasty (TKA) remains controversial. The present study aimed to investigate the closest anatomical reference to surgical epicondylar axis (SEA) among 10 tibial markers in Chinese adults.Methods: This study included examination of 122 normal lower extremities. Briefly, 10 axes were drawn on the axial sections: transverse axis of tibia (TAT), axis of medial edge of patellar tendon (MEPT), axis of medial 1⁄3 of patellar tendon attachment (M1/3), Akagi line, Insall line, axis of medial border of tibial tubercle (MBTT), and axis of anterior border of the tibia 1-4 (ATC1-4). The mean angles between TAT and SEA and that between other axes and the line perpendicular to SEA were measured. Pairwise differences among the 10 tibial axes were examined by applying one-way analysis of variance (ANOVA) and paired t-test.Results: In all the knees, the mean angles of M1/3, Akagi line, Insall line, MBTT, ATC1, ATC2, ATC3, and ATC4 axes were compared to the line perpendicular to the projected SEA and found to be 10.2 ± 5.1°, 1.4 ± 5.0°, 11.9 ± 5.4°, 3.6 ± 4.8°, 12.0 ± 6.9°, 7.2 ± 8.6°, 7.1 ± 10.4°, and 6.6 ± 13.5° external rotation, respectively, and the MEPT axis was 1.6 ± 4.5° internal rotation. The mean angle for TAT was 4.1 ± 5.3° external rotation. The M1⁄3 and Insall line were significantly more externally rotated than Akagi line, MEPT, MBTT, TAT, ATC2, ATC3, and ATC4 axes. No significant differences were noted between the TAT axis and the MBTT axis and among the ATC2, ATC3, and ATC4 axes.Conclusion: The Akagi line, MBTT, and TAT showed good consistency with SEA in the axial femorotibial alignment with knee in extension. The middle segment of the anterior tibial crest also demonstrated good alignment consistency with SEA for the axial femorotibial alignment. Hence, these markers can be used as reliable references for rotational alignment of the tibial component in TKA.

Published: April 2020

The brain lacks a conventional lymphatic system to remove metabolic waste. It has been proposed that fluid movement through the arterial paravascular space (PVS) promotes metabolite clearance. We performed simulations to understand how arterial pulsations and dilations, and brain deformability affect PVS fluid flow. In simulations with compliant brain tissue, arterial pulsations did not drive appreciable flows in the PVS. However, when the artery dilated as in functional hyperemia, there was a marked movement of fluid. Simulations suggest that functional hyperemia may also serve to increase fluid exchange between the PVS and the subarachnoid space. We measured blood vessels and brain tissue displacement simultaneously in awake, head-fixed mice using two-photon microscopy. Measurements show that brain deforms in response to fluid movement in PVS, as predicted by simulations. Our results show that the deformability of the brain tissue needs to be accounted for when studying fluid flow and metabolite transport.

Objective
Post-harvest shrimp losses are a big problem due to the proliferation of spoilage bacteria. Presence and multiplication of these bacteria promotes the emergence of food-borne illnesses. This study was carried out to characterize specifics spoilage bacteria from tropical brackish water shrimp and black tiger shrimp shrimps stored in ambient temperature (25 °C).
Result
22 Bacillus spp; 09 Coagulase negative staphylococci (SCN) and 04 enterobacteria such as 01 Pantoea genus; 01 Serratia plymutica and 02 Serratia rubidaea have been identified. Resistance and virulence genes were searched. All isolates expressed resistance to at least three of antibiotics tested. 03 strains of enterobacteria were succeptible to cetfazidim and Amoxycyclin-Clavulanic Acid. Bacillus showed complete succeptibility to Cefixim, ertapenem and cetfazidim. Staphylocococci were susceptible to clyndamycine. Pantoea spp was resistant to all antibiotics but exhibited intermediate succeptibility to Amoxycyclin-Clavulanic Acid. 04 strains of staphycolocci were positives to mecA resistances genes. None enterobacteria were positives to tetracycline resistance genes. All the strains of Bacillus contained enterotoxin genes, high prevalence of 21 strain to hemolytic enterotoxins and 17 strains to cell-lyse factor production like sphingomyelinase activities. The majority of Bacillus strains present in the study poses a potential risk of food poisoning due to the prevalence of toxin genes found.
