ON THE STABILITY OF A SELF-GRAVITATING INHOMOGENEOUS FLUID IN THE FORM OF TWO CONFOCAL ELLIPSOIDS CARRYING DEDEKIND-TYPE INTERNAL CURRENTS

The second order virial equations are employed to analyze, in a rst approximation, the stability of a self-gravitating uid made up of two confocal ellipsoids carrying internal currents of dieren tial vorticity, which allow their equilibrium. These Dedekind-type gures result because some of the members of a series of inhomogeneous rotating spheroids have null frequencies, from which they bifurcate in sequences of xed ", the body’s relative density. We nd that such sequences have each an instability regime, which is wide at low ", and becomes gradually narrower as " increases. Instability persists|even for very large "|at the nal portion of the sequences, where the gures whose internal ellipsoid has the most prominent equatorial attening are located.
Avoiding dangerous climate: results from the AVOID2 programme

The AVOID2 programme provided evidence for UK Government on what might constitute dangerous climate change and the feasibility of avoiding it. The programme quantified some of the benefits of moving from a world that warms by around 4–5°C to one limiting global warming to below or well below 2°C. Whilst there is evidence that this transition is feasible, it will require early action to reduce emissions and to develop the potential for large‐scale deployment of a range of low carbon technologies.
Design and simulation of a membranes-based acoustic sensors array for cochlear implant applications

In this work we present the design and simulation of an acoustic sensors array for detecting specific frequencies in a range, and allowing their identification from a complex audio signal in order to develop an application for cochlear implants. The sensitivity is obtained when a membrane resonates when stimulated by an audio signal which behaves as a mechanical wave. The structure of each sensor is designed with the concept of MEMS capacitive microphones, formed by a flexible membrane between two rigid backplates. The variation of the distance between the membrane and backplates generates a capacitance change that can pass to an electronic readout circuit. The structure has been designed as a mass-spring system where a set of springs, with the same elastic properties, holds the flexible membrane.
Affordances and Emergence of Concepts

In this paper, we used the a � ordance formalization framework (Sahin et al; Adaptive Behavior, 15(4), 447-472, 2007) to link the concepts represented by verbs and nouns in language to the a � ordance relations that a robot acquires through its interaction with the environment. First, we argued that a verb is linked not to a speciﬁc behavior of the robot, but to a speciﬁc e � ect that di � erent behaviors may generate. We showed how demonstrations made by a human can allow the robot to learn an e � ect prototype in its own sensory-motor space, and use this to command the robot to achieve desired goals. Second, we investigated how the a � ordance relations of objects can be used to create noun concepts (to name objects) and how multi-task learning can utilize the learned object concepts to facilitate the learning of new a � ordances. The re-sults are demonstrated on an iCub humanoid robot platform.
Determinantal Representation of Outer Inverses in Riemannian Space

Starting from a known determinantal representation of outer inverses, we derive their determinantal representation in terms of the inner product in the Euclidean space. We define the double inner product of two miscellaneous tensors of rank 2 in a Riemannian space. The corresponding determinantal representation as well as the general representation of outer inverses in the Riemannian space are derived. A non-zero {2}-inverse X of a given tensor A obeying ρ(X) = s with 1 ≤ s ≤ r = ρ(A) is expressed in terms of the double inner product involving compound tensors with minors of order s, extracted from A and appropriate tensors.
AUGMENTATION OF EFFICIENCY OF SOLID STATE FERMENTATION BY MODIFYING THE CONVENTIONAL REACTOR DESIGN

Considering the limitations of the conventional solid state fermentation in trays (SSF-T), a process modification in the form of solid state fermentation in stacked layers (SSF-SL) was constituted and compared with the former. The later was furnished with a newly devised drying treatment and a replacement of trays by metal gauzes which probably were responsible for an increase of 38.9 % in the production of fungal pectinase under optimized conditions. Univariate optimization of important process parameters of SSF-SL was done to determine their optimum levels which were then used to design the experiments in central composite design (CCD). The fit summary analysis suggested the use of quadratic model and the F-test showed that the model was highly significant at p=0.0001 with high regression coefficient of 0.933. Curvature in the response surfaces demonstrated the nature of interactions between independent variables. The interactions involving the duration of drying treatment suggested the sensitivity of the method to the parameter and its significance in the enhanced productivity.

High-Level Features Organize Perceived Action Similarities

Other people’s actions fill our visual worlds – we watch others run, dance, cook, and laugh on a daily basis. Together, these make up a repertoire of visual actions that we can recognize and reason about. How is this repertoire organized in our minds, so that some actions appear more similar than others? To answer this, we measured the perceived similarity among a large set of everyday actions. We then used a modeling framework to explore which kinds of features predict that similarity. We found that the mental action similarity space is organized primarily by relatively high-level features relating to semantic category and body part involvement. Further, neural similarity within regions that tile the visuo-motor cortex does not predict these judgments well, suggesting that they do not directly support this higher-level space. These results echo recent findings that human similarity judgments in the object and scene domains are best predicted by highlevel feature spaces not grounded in the ventral visual stream (Groen et al., 2017; Jozwik et al., 2017), a pattern that has now been observed across three domains of vision and may reflect a broader principle of the perceptual system.
Privatization of Public Enterprises in Bangladesh: Problems and Prospects

The performance of the public enterprise sector in Bangladesh is poor. The inefficiency of public enterprises places a fiscal burden, diverts limited resources from growth-enhancing public spending to unproductive subsidies, and affects the country's industrial competitiveness. This paper identifies the prospects, problems, and pitfalls of privatization program and policies in Bangladesh. Firstly, the stylized facts about public enterprises are provided and the basic issues in privatization policy as it relates to Bangladesh are discussed. Secondly, the preconditions for efficiency gains arising from privatization are evaluated. Thirdly, the role of public enterprises in the labor market in Bangladesh is examined. Finally, the political and the economic factors that can offset the potential efficiency gains from privatization in Bangladesh are critically analyzed.

Stock Prices: Are Intuitive or Deliberate Persons Better Forecasters?

When it comes to financial decision-making like predicting stock price movements, it would be conceivable that rational people had an advantage over intuitive people. An experiment was conducted to test this hypothesis. Participants of the experiment provided repeated estimates for different shares and it was expected that rational people would end up with more ‘correct’ answers than intuitive people. Additionally, all participants of the experiment (N=59) completed a PID scale questionnaire (Betsch, 2004; Schunk & Betsch, 2006) to evaluate their preferences for deliberate or intuitive decision-making. The PID scale provided four categories to group people according to their preferences. In summary, it was concluded that intuitive people were slightly, but not significantly, better with financial decisionmaking than were rational people. A higher significance was observed from a direct comparison of the four PID categories. Predictions of PID-S-plus participants were significantly more accurate.
Early Life Experience, Maternal Separation, and Involvement of GABA and Glutamate Transporters

The physiological response initiates with activation of the hypothalamic-pituitary- adrenal axis, the autonomic nervous, and the immune systems. All actions promoted cellular adaptive changes in cells and tissues that protect the body and promote their survival. Diverse protocols of maternal separation (MS) in rodents presented alterations in central nervous system (CNS) such as learning disabilities, voluntary alco- hol intake, and neurochemical changes. It is believed that the properties of these early life procedures are mediated by the high plasticity of the developing CNS. During critical development stage, brain regions, mainly those related to aggressive conditions, can have advancement abnormalities occasionally irreversible and thus adjust emotional processing when they grow to be adults. Early postnatal period and relationship between mother and infant are essential of normal stress response and emo- tional behavior. Probably, it involves the activation of intracellular signaling pathways, genome adaptations, adjusts in gene expression, and neural action. The objective of this article is to provide an overview of the current state of knowledge in the field focused on the maternal separation model, early life experience of postnatal stress, and the involvement of γ-aminobutyric acid (GABA) and glutamate transporters.
Effect of Antecedent Rainfall Patterns on Rainfall-Induced Slope Failure

Rainfall-induced slope failure occurs in many parts of the world, especially in the tropics. Many rainfall-induced slope failures have been attributed to antecedent rainfalls. Although it has been identified as a cause of rainfall-induced slope failure, the pattern or distribution of the antecedent rainfall has not received adequate attention. In this study, parametric studies were performed by using three typical rainfall patterns, identified by analysis of available rainfall data for Singapore and two different soil types to represent high- and low-conductivity residual soils of Singapore. Antecedent rainfall patterns were applied on soil slopes and a transient seepage analysis was conducted. The computed pore-water pressures were used in stability analyses to calculate the safety factor of the slope. Results indicated that antecedent rainfall affected the stability of both high-conductivity (HC) and low-conductivity (LC) soil slopes. However, the stability of the LC soil slope was more significantly af.
Issues of a Combination of Ultrasonic Doppler Velocity Measurement with a Venturi for Multiphase Flow Metering

Multiphase flowmeters (MPFMs) available today are mostly based on a combination of differential pressure measurement, provided by at least one flow constriction, such as a Venturi device, with phase holdup measurement based on nuclear techniques, electromagnetic techniques, or both. This paper investigates the issues of combining the ultrasonic Doppler velocity measurement with the differential pressure measurement for multiphase flow metering. The intention is to measure at least one “useful” velocity of the flow, such as the bulk liquid velocity or the homogeneous mixture velocity, which can then be combined with a measured differential pressure across a “constriction” device, such as a Venturi, to derive parameters needed to calculate liquid and gas flow rates. An ultrasonic Doppler velocity sensor has been tested in combination with a Venturi under multiphase flow conditions. The results show that, due to the effect of gas bubbles in the liquid phase, the interrogation depth of the ultrasonic wave is often limited to a shallow liquid region near the pipe wall. As a result, the ultrasonic Doppler sensor cannot reliably measure the bulk liquid velocity, or the homogeneous velocity. It is generally difficult to interpret the
The Future Potential of Internet of Things

Purpose: To define the Internet of things and to analyze it as a background for the internet of services. Design/methodology/approach: The article discusses potential possibilities and problematic issues concerning the Internet of things (IoT) and Internet of services (IoS). The debates concerning IoT and its possible application fields have continued for more than ten years. The technological background is there and the fields of application are broad. However, there is still a lack of understanding about the possible benefits that technology could give to various bodies if applied correctly. This article is based on comparison and analysis of scientific articles, research papers and case studies related to the potential for IoT and its implementation in IoS. Theoretical findings: IoT is a logical evolutionary step for the internet. Despite the technological background, the concept of objects which are aware of their surroundings, allow to manipulate them by defining different rule patterns and ensuring interaction possibilities with other objects or human beings. The necessity for web-based services is increasing along with the technological gadgets which support them. Applying things, which are connected in a network, could revolutionize many industry and service sectors and create new service provision and administration methods based on information technology. However, there are many problematic issues and research challenges related to the IoT. Few of the most significant are related to standardization of technology, legal regulation and ethical aspects concerning the IoT technology. Research limitations/implications: The IoT is a popular trend promoted by the business sector and governmental bodies. There are few comprehensive studies and projects which talk about the benefits that business and society could gain from the IoT. There is a lot less information about the possible risk and problematic aspects, and a lack of agreements between the developers of technologies. In the scientific community arguments are also varied depending on the technologies used and regulation models adopted. For that reason it is possible to review the topics only focusing on narrow, but most comprehensively analyzed spectrum of problematic issues. Practical implications: Theoretical framework for future research in the field was developed.
BIOMECHANICS OF MUSCULOSKELETAL SOFT TISSUES

The musculoskeletal system has four primary soft tissues: skeletal muscles, tendons, ligaments and articular cartilages. Skeletal muscles are contractile, and their primary function is to shorten and produce force and so cause movements at joints. Muscle contraction occurs through cyclic interactions of myosin-based cross-bridges with actin. Contractions are fuelled by the hydrolysis of adenosine triphosphate (ATP). Tendons connect muscles to bones. Because of their nearly elastic properties, they are excellent for storing and releasing energy during cyclic movements and they affect the contractile conditions, and thus the properties of muscles in the human body. Ligaments connect bones across joints. Ligaments guide the movements of joints, they keep the articulating surfaces aligned for optimal congruence and they are associated with providing feedback about the orientation of the bones that make up a joint. Articular cartilage is a thin, avascular, aneural, layer of connective tissue covering the surfaces of bones in synovial joints. The primary functions of cartilage include the transmission of forces across joints, the distribution of forces across the joint surfaces, and the provision of smooth surfaces for optimal joint function.

Secure and Efficient Way of Handling MedicalRecords in Cloud

Personal health records (PHRs) are touted as a new convenience technology for consumers. It enables the patients to create a health information of their own in a centralized way, which alleviate the storage, access and sharing of health data in the cloud environment. By storing the health information in the cloud various security issues should arise such us authorization, key management and efficient user revocation, therefore, before outsourcing the PHR in the cloud, it is a promising method to encrypt the PHR using Attribute Based Encryption. Existing cryptographic schemes are planned for single owner settings, here, dealt with multiple owner scenarios which reduce the key management complexity for owners and users. Enhancing the MA-ABE scheme to handle efficient and ondemand user revocation, and prove its security. The experimental results will show the security and efficiency of the proposed system.
Ciddi yanık travması olan hastalarda hastane kaynaklı idrar yolu enfeksiyonu sıklığı ve risk faktörlerinin araştırılması

BACKGROUND This study aimed to investigate the prevalence and risk factors for hospital-acquired urinary tract infections in patients with severe burn injuries. METHODS In this study, patients treated due to their burn injuries of greater than 20% between August 2009 and April 2012 in Bozyaka Training and Research Hospital Burn Center were assessed retrospectively. Sixty nine patients (30 [43.5%] males, 39 [56.5%] females; mean age 40.1±16.7 years) were included into the study. RESULTS DM, duration of the catheter and catheter care showed a statistically significant correlation with hospital-acquired urinary tract infections (p<0.005). DISCUSSION A large number of hospital-acquired urinary tract infections are associated with urinary catheterization. In addition, removing urinary catheter within the shortest time possible is another issue to be considered for the prevention of these infections. If the catheter has to remain for a longer time, regular catheter care is recommended.
Reconocimiento de caras en la esquizotipia

Title: Face recognition in schizotypy. Abstract: Studies suggest disturbances of self in schizophrenia and in schizotypy, and unusual perception of own and other faces in schizotypy. The purpose of this study was to explore possible differences between high and low scores on schizotypal questionnaires and self and others-face rec- ognition, and confirm whether the cognitive-perceptual and disorganiza- tion dimensions of schizotypy, but not the interpersonal dimension, sig- nificantly correlated with such disturbances, as observed in previous stud- ies. A sample of 219 nonclinical adolescent and young subjects (53% fe- males) completed the Self-Face Recognition Questionnaire (SFRQ), the Schizotypal Personality Questionnaire-Brief (SPQ-B), and the Oviedo Schizotypy Assessment Questionnaire (ESQUIZO-Q). Mean age of the participants was 16.3 years (SD = 1.18). Comparisons between those par- ticipants scoring high and low in schizotypal traits offer further support that positive (Cognitive-perceptual and Disorganization) traits significantly correlate with face recognition difficulties; demonstrating girls more distur- bances than boys in face recognition, probably due to higher scores in the Cognitive-perceptive dimension.
Adsorption of Amaranth Dye onto Alumina Reinforced Polystyrene

Adsorptive removal of toxic amaranth dye by alumina reinforced polystyrene (ARP) composite was studied as a function of contact time, pH, initial dye concentration, and temperature. The results indicated that adsorption was strongly dependent on pH and temperature of the dye solution. The adsorption was favored at low pH with the maximum removal at pH 2.0. Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich (D-R) models were used for the description of adsorption equilibrium data and the best interpretation for the experimental data was given by the D-R model. The adsorption kinetics was tested using pseudo first order, pseudo second order, Elovich, intraparticle, and film diffusion models and the removal by ARP followed a pseudo second order kinetics. Thermodynamic studies revealed that both adsorption and desorption was spontaneous and endothermic in nature. From the exhausted adsorbent, about 70 and 96% desorption was obtained with (99%) CH 3 OH and 0.1 M NaOH, respectively.
Returns to Education and the Mankiw-Romer-Weil result.

Mankiw, Romer and Weil [1992] found that, by adding a measure of school enrolment to capital and labour, a cross-country regression displays income convergence. However, their assumption that this derives from an augmented Solow model requires implausible differences in educational productivity across countries. By contrast, if educational productivity is constant, their fitted equation would be consistent with AK-type spillovers in goods production, but where educational costs damp growth. The MRW result suggests that endogenous growth theorists can be right about either technological spillovers or rising educational productivity, but not about both.
A Moderating Effect of Leadership Tenure on the Relationship between Leadership Self-Efficacy and Effective Leadership Behaviour

This study aims to examine the influence of leadership self-efficacy on effective leadership behavior with a moderating effect of leadership tenure in Nigerian commercial banks. Based on the existing literature review conducted, a conceptual framework was developed based on suggestions for future studies to test this relationship. Self-efficacy theory was used to explain the relationship among the constructs considered in this conceptual model. The study used a survey design which was aided by the use of questionaire. A sample of 358 branch managers of the Nigerian commercial banks was drawn through a stratified random sampling. A combination of descriptive and inferential statistics were used to analyse the data collected using the Statistical Package for Social Science (SPSS) for Windows. The findings of this study reveald that leadership self-efficacy has a significant positive relationship effective leadership behaviour. In the same vein, further investigation using hierarchical multiple regression shows that the moderating effect of leadership tenure on the leadership self-efficacy and effective leadership behavior relationship was found not to be significant. Finally, discussion, managerial and policy implications, recommendations and suggestion for future research were also highlighted in the study.
