Concavity properties for quasilinear equations and optimality remarks

In this paper we study quasiconcavity properties of solutions of Dirichlet problems related to modified nonlinear Schrödinger equations of the type $$-{\rm div}\big(a(u) \nabla u\big) + \frac{a'(u)}{2} |\nabla u|^2 = f(u) \quad \hbox{in $Ω$},$$ where $Ω$ is a convex bounded domain of $\mathbb{R}^N$. In particular, we search for a function $φ:\mathbb{R} \to \mathbb{R}$, modeled on $f\in C^1$ and $a\in C^1$, which makes $φ(u)$ concave. Moreover, we discuss the optimality of the conditions assumed on the source.

EFL teaching practicums in Vietnam: The vexed partnership between universities and schools

The teaching practicum is an integral part of any pre-service teacher training programme. It is when trainee teachers move from university studies to actual school teaching practice under field supervision. However, the partnership between universities and schools in organising the practicum has been questioned. This paper reports on a study investigating the effectiveness of the teaching practicum for English as a foreign language (EFL) trainee teachers at three universities in Ho Chi Minh City as manifested in the training programme, the practicum arrangements and the mentoring practices. Data were collected by means of interviews with key practicum stakeholders including six university academic staff members, six university mentors, six school mentors and twelve EFL trainee teachers. Documents related to the teaching practicum from the three institu-tions also provided a rich source of qualitative data together with questionnaire data obtained from 141 final-year EFL trainee teachers. Some interesting differences were found in the way the individual universities worked with the host schools although a consistent theme emerged that showed a low level of university-school collaboration in supporting pre-service English language teachers during the practicum. Implications for EFL teacher education and the reinforcement of partnerships between universities and schools in prepar-ing EFL teachers are discussed.

Studies of High Solidity Ratio Hydrofoil Impellers for Aerated Bioreactors. 2. Air—Water Studies

Abstract This second part of a four‐part series of papers reports on the hydrodynamic and power characteristics of two commercial, high solidity ratio, hydrofoil impellers, the Prochem Maxflo T and the Lightnin A315, in an air—water system. Studies were conducted primarily in a mixing vessel of diameter 0.56 m. The influence of operating conditions (impeller speed and gas flow rate) and sparger position and geometry on bulk flow patterns, gas filled cavity formation, and power consumption have been investigated in detail. In the turbulent Reynolds number region, the unaerated impeller power numbers are constant with average values of 1.30 for the Prochem and 0. 76–0.84 for the A315, depending on impeller position relative to the base of the vessel. Gassed power consumption is closely linked to cavity type and flow pattern. In particular, the development of large cavities causes a significant reduction in power drawn, impeller pumping capacity, and gas dispersion capability. As with downward pumping mixed flow impellers, two characteristic gas loading regimes, direct and indirect loading, can be identified. Under certain conditions, severe hydrodynamic instabilities over the transition between the two regimes give rise to very large torque and power fluctuations. Changes in reactor geometry can have a significant effect on impeller performance. Thus, sparger type and position have a strong influence on relative power drawn, gas handling capability, power required to disperse gas and stability of operation. Of the configurations studied, the use of a large ring sparger ( D S / D = 0.8 D ) at a large sparger—impeller separation is suggested, since relative power drawn, gas handling capability, and energy efficiency in dispersing gas are all enhanced.

Modeling of the tumor microenvironment to highlight nonlinear interactions between chemotherapeutic response and macrophage polarization state.

e24120 Background: The influence of tumor microenvironment characteristics on cancer progression and efficacy of chemotherapy has been the focus of intensive research. In particular, macrophages are a dynamic cell population that can assume various phenotypes based on tumor microenvironment characteristics. The influence of macrophage phenotype on therapeutic efficacy remains poorly understood. Macrophages can either aid or hinder tumor growth, with disease prognosis hinging on the proportion of pro-inflammatory and anti-tumorigenic M1 vs. anti-inflammatory and pro-tumorigenic M2 phenotypes. Repolarization of macrophages in the tumor microenvironment from the M2 to M1 phenotype has emerged as a potential approach that harnesses the body's own immune system to fight cancer. Methods: Understanding the complex interactions between chemotherapy and macrophage populations in the tumor microenvironment could benefit from mathematical and engineering principles. We implement a modeling framework to evaluate tumor response to chemotherapy, including the effect of macrophage phenotypes in the tumor microenvironment on tumor growth and therapeutic outcome. M1 and M2 phenotypes are integrated into a model of tumor growth representing a metastatic lesion in a highly vascularized organ such as the liver. Behaviors simulated include M1 release of cytotoxic nitric oxide and M2 release of growth-promoting factors. Results: We simulate a hypothetical therapy-induced macrophage repolarization regimen from the anti-inflammatory M2 phenotype to the pro-inflammatory M1 phenotype in conjunction with chemotherapy administration. Surprisingly, the model predicts that chemotherapy applied in a tumor microenvironment that contains mixed M1 and M2 macrophage phenotypes is more effective than with only M1 macrophages. Conclusions: Fine-tuning the ratio of macrophage phenotypes in the tumor microenvironment during chemotherapy may be therapeutically beneficial. A proposed mechanism is that M2 macrophages potentiate the chemotherapy effect by promoting tumor cell proliferation that sensitizes these cells to agents acting on dividing cells.

Quantum three-body scattering problem in the adiabatic hyperspherical representation

The adiabatic hyperspherical (AH) approach to the quantum three-body problem is considered. It is proven that the AH harmonics are complete and differentiable with respect to the hyperradius for a large class of two-body potentials. For the case of short-range potentials, the scattering theory is studied in the framework of the AH approach. The asymptotics of the AH potential curves, harmonics, and coupling matrix elements are derived, as well as the structure of the three-body wave operators and, the S-matrix in the AH representation is investigated.

Spatiotemporal Evolution Patterns and Driving Factors of Synergistic Development of Culture, Sports, and Tourism Industries: The Case Study of China

Synergistic development of the culture, sports, and tourism industries is an emerging trend in China, providing new formats for industrial evolution and fresh momentum for industrial upgrading. Therefore, building a robust framework to evaluate the synergistic development is relevant to China’s economic and social development. This study used a coupling coordination model to calculate the coupling coordination degree of the three industries, for 31 provinces in China from 2013 to 2017. Subsequently, it employed spatial autocorrelation techniques and GeoDetector to identify factors affecting the synergistic development from global and local perspectives before discussing the driving mechanisms. The results showed that (1) the synergistic development of the three industries was generally stable with a slight imbalance. (2) The development level varied across regions. The general spatial pattern was low in northeastern and western China, stable and average in the central region, and high in the eastern region. (3) The synergistic development has a prominent “proximity dependence” effect reflected by a notable spatial agglomeration feature and positive spatial autocorrelation trend and (4) twenty-one indicators of six driving factors (industrial pulling force, population supporting force, consumer purchasing power, transportation pushing force, resource attraction force, and economic driving force) affected the synergistic development.

Strength Performance of Blended Ash Based Geopolymer Mortar

Geopolymer is a based on inorganic alumino-silicate binder system. Geopolymeric materials are formed using materials that containing silica and aluminium such as fly ash and rice husk ash, which activated by alkaline solution. This paper presents the study on the effect of replacement of SSA in RHA based geopolymer, types of curing and different molarity of NaOH used on the strength of Sewage Sludge Ash (SSA) and Rice Husk Ash (RHA) based geopolymer mortar incorporating with three (3) different mix proportions. Based geopolymer mortar was synthesized from treated sewage sludge and rice husk undergoing incineration process in producing ashes, activated with sodium silicate and sodium hydroxide solution by ratio of 2.5:1 and solution to ash ratio of 1:1. Molarity of 8M and 10M NaOH were used. The percentages of SSA replacement were 0%, 10% and 20% by weight. Compressive strength was conducted at age 7, 14 and 28 days to see the development of strength with two curing regimes, which are air curing and oven curing (60°C for 24 hours). From the research conducted, the ultimate compressive strength (6.28MPa) was obtained at zero replacement of SSA taken at 28 days of oven curing with 10M of NaOH. This shows that RHA, which is rich in silica content is enough to enhance the strength of geopolymer mortar especially with high molarity of NaOH.

Sound field synthesis of arbitrary moving sources using spectral division method

The spectral division method (SDM) is one of several sound field synthesis techniques of spatial sound reproduction. The synthesis accuracy of SDM is usually higher than that of wave field synthesis (WFS). However, existing SDM-based sound field synthesis methods are developed for virtual sources moving uniformly along a straight trajectory. This Letter proposes a 2.5-dimensional SDM driving function for arbitrary moving sources. Numerical simulations have validated the driving function. The results indicate that the synthesis error of the SDM with the proposed driving function is lower than that of WFS, especially when the virtual source is close to the secondary sources.

Clinical application of a rapid and practical procedure of transabdominal ultrasonography for determination of pregnancy and fetal viability in cows

To apply a rapid and practical procedure of transabdominal utlrasonography for determination of pregnancy and fetal viability in cows. The study was carried out on 104 clinical cases of cows. The cows were examined by rectal palpation and transabdominal ultrasonography in a standing position. Results showed that determination of pregnancy and fetal viability were obtained significantly faster using transabdominal ultrasonography than rectal palpation. The accuracy, sensitivity and specificity of rectal palpation were 67.4%, 84.8% and 48.8% for detection of pregnancy, and 33.3%, 90.4% and 1.9% for determination of fetal viability, respectively. While these three parameters for transabdominal ultrasonography were 100% for both pregnancy and fetal viability determination. The pregnancy diagnosis was very fast at five months of gestation, and a significant negative but rather good correlation (r= −0.707) was observed between the gestation period and the required time for pregnancy diagnosis. The fetal viability was determined easily and fast at four months of gestation, and there was a significant positive correlation (r=0.32) between the gestation period and the required time for finding the fetal viability. Transabdominal ultrasonography is a reliable procedure for determination of pregnancy and fetal viability especially for cows between fourth and sixth months of gestation.

Count Freducci's Nautical Charts, Papal Cartography, and Trasmission: A Reply to Article by Chrt Van Duzer (2017)

The comment on my paper concerning Conte di 'Ottomano' Freducci by Professor Chet Van Duzer is welcome for a number of reasons. Chet Van Duzer, in his BLJ article, 'Nautical Charts, Texts, and Transmission: The Case of Conte di OttomanoFreducci and Fra Mauro' (pp. 1-4), points out the inherent biases one encounters in interpreting descriptive legends on non-traditional nautical charts, and he reiterates a point I made: namely, that the recondite nature of some of the new information that nautical charts by Count Freducci include are of particular interest to shed light on the process of commissioning and creating nautical charts in Medieval and Renaissance Italy

Evaluation of conditions for quality logistic services in the area of refrigerated transport

Logistic services are evaluated primarily by measuring customer satisfaction. A satisfaction measurement provides information on the operations of an organization and how effective it is in meeting the customers’ needs. The aim of this paper is an evaluation of the organizational conditions of the customer satisfaction level regarding the quality of logistic services within three groups of transport of food products. In turn, the range of the conducted research involved aspects of organizational conditions, such as: effects of the cooperation with a provider of logistic services in the field of transport of food products and the usefulness of the compulsorily implemented management systems in an enterprise. The studies were carried out based on a research survey questionnaire addressed to purchasers of logistic services. The study subjects were companies that use services for refrigerated transport. The χ2 test was used to define the relationship between the effects of the cooperation with a service provider and the spatial range of their activities, the respondents’ job seniority and education, as well as to estimate the dependence of the evaluation of usefulness of the compulsorily implemented management systems in a company on the spatial range of their activities.

[West Nile arbovirus antibodies with hemagglutination inhibition (HI) in residents of Southeast Anatolia].

937 sera collected from different persons in Southeast Anatolia were studied for antibodies against West Nile - Virus by HI test. 763 out of 937 sera were from the research area, 42 from the neighboring districts and 21 from soldiers recently come to the research area, the features of the remaining 111 sera, except the ages of 4 could not be recorded. In the sera from the research area the West Nile antibodies were positive in 41.80%. The positive ratios were 40.49% in Diyarbakir, 47.83% in Mardin, 44.82% in Siirt, 38.09% in Urfa and 41.17% in Elâziğ. In 916 sera, the positive ratio was 40.06%. The ratio increased with the age, 5 out of 21 sera from soldiers were positive. It seems that in research area an active West Nile virus or a closely related one is found. We think that in neighboring areas some active foci of West Nile wirus are found.

A semiquantitative assay for CD8+ T-cell-mediated suppression of human immunodeficiency virus type 1 infection

A reproducible, semiquantitative assay was developed to measure the level of the anti-human immunodeficiency virus type 1 (anti-HIV-1) suppressive activity of CD8+ T cells. The assay had a wide dynamic range and could be applied to a relatively small number of fresh and cryopreserved peripheral blood mononuclear cells and purified CD8+ T cells. The suppressive activity was not due to cytolytic activity and was not major histocompatibility complex class I restricted. Suppression of HIV-1 infection by CD8+ T cells was consistently demonstrable with both endogenously infected autologous CD4+ T cells and exogenously infected allogeneic CD4+ T cells. This assay can be used to monitor the level of antiviral activity of CD8+ T cells in a retrospective and prospective manner in studies of the natural history of HIV-1 infection and of subjects receiving anti-HIV-1 therapy and vaccines.

Definition, Incidence and Psychopathological Consequences of Child Abuse and Neglect

In children and adolescents, child abuse and neglect can produce a decline in their biologi‐ cal, psychological and social functions. Child maltreatment in childhood and adolescence is recognised as an important psychopathological risk factor and is associated with poor psy‐ chological function in childhood and adolescence and adulthood. In this respect, we empha‐ sise that it is wrong to believe that current knowledge has enabled the identification of clearly differentiated consequences for each type of child maltreatment. There is a high de‐ gree of co-morbidity among the different types, in such a way that many children experi‐ ence more than one form of maltreatment and display common consequences. Moreover, it still needs to be clarified whether child abuse and neglect produces a general vulnerability towards psychopathology, in such a way that other factors would be responsible for the form finally adopted by psychopathology.

Identification Analysis of Influencing Factors of Construction Business Success: A Case of the Malaysian Construction Industry

Although the construction industry is one of the important components of the nation’s economic development, nevertheless, a nation can only fully benefited from the construction activities if it has an efficient and effective construction industry. Against the traditional conceptions of success in the construction industry, this paper attempts to explore the factors that influence the success of the construction enterprise from the viewpoint of an entrepreneurship perspective. In this regard, the importance factors to the construction enterprise success were determined based on the entrepreneurship literature and experts’ opinions, and categorized into four dimension and eighteen factors. Then, the Decision Making Trial and Evaluation Laboratory (DEMATEL) technique was applied to explore the causal relationships among the factors. The results revealed that three factors were of great importance to the success of the construction enterprise, namely ‘Business and Management Competencies’, ‘Technical Competencies’, and ‘Technological Competencies’. It is advised that if the construction enterprises desire to obtain high potential in business success, they should focus on these factors by enhancing their practice in this areas.
