A Study of Fnac of Cervical Lymph Nodes in Tertiary Hospital,Kurnool

Background: Fine Needle Aspiration Cytology (FNAC) is a reliable and least expensive method suitable for developing countries like India for the investigation of lymphadenopathy. Knowledge about the pattern oflymphadenopathy is useful in pathological reporting as well as in many clinical settings with diagnostic dilemma. This is a baseline study to investigate the pattern of cervical lymphadenopathy by lymph node FNAC . Methods: A retrospective study was conducted byanalyzing the case reports on cervical lymph node FNAC from five years records (July 2010 to June 2015) at Department of General Surgery,Government General Hospital,Kurnool.Review of all cytological reports were done according to standard guidelines and the diagnosis wasclassified and correlated with patients’ age and ethnicity to explore the pattern and association. Results: Of 508 cervical lymph node FNAC cases, 50.4% was reactive non-specific, 22.4% was tubercular, 4.8% malignant, 10% chronic granulomatous and the remaining was acute suppurative (12.4%). Highest incidence ofmalignancy was seen in the fifth decade (50%). Whereas, tubercular lymphadenopathy was found with increasingfrequency through childhood (10.5%) and adolescence (21.7%) to young adulthood (30.4%), probably indicativeof waning immunity of BCG vaccination. Conclusion: The relationship of malignant and tubercular lymphadenopthy with age and ethnicity deserves furtherstudy. Efforts at preventing tubercular and early diagnosing malignant lymphadenopathy and reducing morbidity ingeneral will find great usefulness in such associations.
Are Computer Experience and Anxiety Irrelevant? Towards a Simple Model for Adoption of E-Learning Systems

Massive growth of technology based e-learning systems is enabling student access to academic content from higher education institutions around the world. This study explores the antecedents of behavioral intention of students to use e-learning systems in university education to supplement classroom learning. A quantitative approach involving a structural equation model is adopted and research data collected from 358 undergraduate students is used for analysis. The study framework is based upon the technology acceptance model (TAM) and three external factors are proposed to influence the behavioral intention of students to use e-learning. Frequently used external factors in previous researches like computer experience and anxiety were not used and alternate factors were explored. Results show that self-efficacy, enjoyment and results demonstrability have a significant positive influence on perceived usefulness and on perceived ease of use of the e-learning system. The study contributes to understanding such contributory factors from the viewpoint of a student by suggesting that these factors hold well in the Pakistani academia culture where sufficient relevant empirical evidence did not exist due to lack of prior studies.
Teachers' Experiences towards Usage of Learning Management System: CANVAS

The automated way of learning and interacting with students bids a lot of advantages that can be accomplished through different system. Among them, the most popular approach is the use of a learning management system. Canvas, the world's most reliable LMS is a platform being introduced in universities of the Philippines. This research aims to examine the experiences of instructors towards usage of Canvas according to the UTAUT (Unified Theory of Acceptance and Use of Technology) model. A total of 130 instructors teaching different courses and are exposed to the use of CANVAS participated in this study. An adopted and modified set of questionnaire based on UTAUT used to collect data which is then descriptively analyzed using SmartPLS 3. Results of this study encourage teachers to maximize the use of technology. Significant results and information were also obtained for administrators, instructors and students on how to improve effective usage of the system.
Low-Cost Photovoltaics by Electrodeposition of Silicon PN Junctions

The goal of this research was to develop a new approach to produce Si-based photovoltaics for solar energy conversion to electricity. This process should be less expensive and environmentally friendlier than the current Siemens process based on reduction of SiO2 with carbon at high temperature: SiO2 + C à Si + CO2. Our major successes are: 1. The only demonstrated electrochemical deposition of Si films on carbon that show photo activity. 2. The development of a photoelectrochemical method for testing Si electrodeposits without producing a solid-state p-n junction. 3. The only Si synthesis process described that does not produce CO2, i.e. SiO2 à Si + O2. 4. The first preparation of solid-state p-n junctions by electrodeposition. Reliable energy supplies that are cost-effective and environmentally-friendly are critical for sustainable energy development, especially in developing countries. Billions of people, especially in India, Africa and South America, have no to very limited access to electricity. Solar photovoltaics (PV) provide promising solutions. Crystalline-silicon solar cells have dominated the PV market for the past several decades and are most likely to continue to be the primary technology for the PV industry in the future. However, high cost and energy consumption, and the presence of a carbon footprint during PV module production prevent widespread promotion of solar PV throughout developing countries. Our major successes address these obstacles through judicious design, synthesis, and characterization of electrodeposited silicon for solar energy PVs as described briefly.
ON THE FINITE DEFORMATIONS OF TWO DROPS DUE TO ELECTRIC FIELD

In this paper we investigate the finite deformations of two drops due to electric field. The fluids are homogenous, incompressible and Newtonian. Reynolds’ number is assumed small enough to investigate the problem in quasisteady Stokes’ approximation. It is also supposed that the initial form of the drops are spherical, but could be with different radii and different fluid phases. The electric and hydrodynamic problems are separated and the electric one has influence on the hydrodynamic with the boundary conditions. The Maxwell’s equations are turned to Laplace’s equations, and together with Stokes’ equations are solved by semianalytical-seminumerical method. We use boundary-integral type of these equations to solve them by the method of boundary elements. The kinematics condition gives the new form to the particles. The results obtained indicate that interactions between two and three fluid phases due to electric field lead to deformations of the drops. Parametrical analysis of the deformations of some dimensionless parameters of the problem has been given graphically.
MIDDLE MIOCENE CARNIVORA OF NEW MEXICO (TESUQUE FORMATION): SPECIES PATTERNS, RICHNESS, AND FAUNAL TURNOVER

Recent field work and research call for a new look at the carnivorans from the middle Miocene of New Mexico. Here changes in carnivoran guilds through time within the Tesuque Formation as well as the carnivoran diversity in each member are described. The Tesuque Formation in New Mexico contains fossiliferous layers of strata that span the late Hemingfordian through the Clarendonian (and potentially into the earliest early Hemphillian). Borophagines were the dominant carnivorans, and presumably the dominant predators, during the middle Miocene in New Mexico. However, when borophagines become less abundant, canines become more abundant, showing an inverse relationship and perhaps leading to instances where members of these groups utilize similar niches. Hesperocyonines are only present in the early Barstovian, while the large amphicyonids are found only in the late Barstovian, potentially filling an open niche left by the hesperocyonines. While carnivoran diversity drops after the Barstovian, mustelids persist in the early Clarendonian. Felids tend to become less numerous through time, perhaps allowing mustelids to fill the role of the small predators in place of Pseudaelurus (among others), and these may have in turn been replaced by small canines. In addition, this study records the first occurrences of several carnivorans in distinct members, or in the Tesuque Formation as a whole, including the first occurrence of mustelids (non-mephitine mustelids) in the formation. While the carnivoran fauna from the middle Miocene of North America is more diverse, it is noted that the Tesuque carnivoran fauna has a higher percentage of canids, and a lower percentage of mustelids and procyonids. Statistical analyses show each carnivoran group is found in most of the members and so do not cluster differently with the exception of Hesperocyoninae. The Barstovian Skull Ridge and Pojoaque members are the most statistically similar in terms of their carnivoran diversity.
Acceptance and Use of Information Technology: Understanding Information Systems for Indonesia’s Humanitarian Relief Operations

Disaster management includes distributing logistical assistance to disaster victims. The implementation of this distribution must occur at the right time, at an appropriate location, on target and be appropriate to the needs of the victims. This research aims to design an information system to improve the performance of disaster relief operations by managing the information while monitoring and evaluating humanitarian relief operations.Consequently, understanding the primary determinants of user acceptance behavior has become a vital aspect in the successful implementation of the information system. The Unified Theory of Acceptance and Use of Technology (UTAUT) model is a tool to investigate and give a better understanding of the factors that affect the potential users’ acceptance and use of an information system. This research used 131 different informants from different groups of potential users to measure performance expectancy, effort expectancy, social influence, and facilitating conditions. The results have shown strong relationships between four aspects of the measurements for the acceptance of all parties involved in humanitarian relief operations.
The effect of Task Repetition with Dictation Intervention on the Development of Chinese University Minority EFL Students’ Spoken English: A Case Study of Honghe University in Yunnan Province

The current paper shows and discusses the findings of a quasiexperimental study with a group of first-year minority students (N=12) at Honghe University in Yunnan province, China, which investigated the application of TR with post-task intervention (dictation) on minority university students’ spoken English fluency. In this regard, a speaking practice (4/3/2 technique) with dictation intervention including 16 monologue topics, a pre-test and a post-test were conducted to explore the development of the minority students’ spoken English fluency under the TR with dictation intervention. Also, a focus-group discussion was adopted to explore the effects of TR with dictation intervention on the improvement of the spoken fluency from the students’ perspectives. The results show that the students’ spoken fluency was developed through the calculation of four variables, including the mean length of the run (MLR), phonation time ratio (PTR), average pause length (ALP) and repair per 100 syllables (R100).

Original hardware-software method for treatment of infected superficial wounds in a liquid environment

Aim ― development of a hardware-software system allowing to treat infected superficial wounds in a liquid environment, designed to provide continuous flow of various irrigation solutions (depending on the wound healing stage) under airtight and waterresistant film tightly fixed over the wound. Methods ― in this experiment wound irrigation with antiseptic, oxidizing antiseptic and osmotically active agents with subsequent exposure and drainage was performed using the novel device. Efficacy of the proposed hardware-software system was evaluated by comparing it with standard wound dressings by planimetry and wound biopsy results. Results ― according to study results the novel device reduces the time of wound healing by 26.1%, while the time to wound proliferation is 1.7 times shorter when compared with standard wound dressings. Conclusion ― the proposed method stimulates wound repair and limits purulent inflammation in infected wounds. Using the novel method of superficial wound management helps to prevent the development of re-infection and suppuration.
INFLUENCE OF THE SUBSTRATE GEOMETRY ON THE ONSET OF PARTICLE MOTION AT LOW PARTICLE REYNOLDS NUMBERS

Using a standard rheometer and a camera equipped with a macro objective, we study the critical conditions for incipient motion of a single spherical particle deposited on a regular substrate under laminar flow conditions. The substrates are triangular and quadratic arrangements of identical glass spheres of same size. For the latter, the distance between the substrate spheres is varied, resulting in a partial shielding of the deposited particle to the shear flow. We find that for particle Reynolds numbers in the range between 3x10 and 3, the critical Shields parameter is independent from the particle density and from the particle Reynolds numbers but it depends significantly on the geometry of the substrate. We show how it is affected by the geometrical arrangement, the distance between the substrate spheres, and by the angle of orientation of the substrate with respect to the main flow direction.
Intercultural sensitivity: A comparative study among Business English Undergraduate Learners in two Countries of Iran and China

One of the major aspects of intercultural communication competence is intercultural sensitivity which is gaining increasing attention in different disciplines. Intercultural sensitivity is important because it reduces cultural barriers between people interacting from different cultures. This paper focuses on the importance of intercultural sensitivity and shares the results of a comparative study on the intercultural sensitivity among two countries of Iran and China. For this purpose, 40 Iranian and 40 Chinese male and female undergraduate Business English students completed the intercultural sensitivity questionnaire comprising five factors with 24 items developed by Chen and Starosta (2000). The results showed that in all five dimensions of the intercultural sensitivity including “Interaction Engagement”, “Respect for Cultural Differences”, “Interaction Confidence”, “Interaction Enjoyment”, and “Interaction Attentiveness”, Iranian participants had greater scores compared to Chinese participants. For both countries by increasing the age, the scores of all five dimensions of intercultural sensitivity increased too. Also, the results indicated that both Iranian and Chinese male participants had greater level of intercultural sensitivity in dimensions of “Interaction Engagement”, “Respect for Cultural Differences”, and “”Interaction Confidence” compared to female ones. However, gender did not have any impact on two intercultural sensitivity dimensions of “Interaction Enjoyment” and “Interaction Attentiveness”.
Timisoara Journal of Economics and Business

The relationship between liquidity and profitability is one of the most interesting topics in the corporate finance research. Having in mind that the pharmaceutical industry is one of the most competitive sectors globally and that its substantial investments in research and development make this industry a key asset for a country’s economic well-being, this paper examines the liquidity-profitability trade off in pharmaceutical sector of RNM. The empirical research engages the secondary annual financial report data of the two pharmaceutical companies listed on Macedonian Stock Exchange (MSE) over the period from 2006-2016. Current ratio (CR), quick ratio (QR) and cash ratio (CAR) were used as measures of liquidity while return on assets (ROA) and return on equity (ROE) were used to measure profitability as a dependent variable. The statistical tests used to evaluate the effects of liquidity on profitability involved descriptive statistics, correlation and regression analysis. The findings suggest that there is no significant relationship between profitability and liquidity determinants of the listed North Macedonian pharmaceutical firms. Regarding practical implications, these findings can help managers overcome dilemmas with respect to the liquidity and profitability tradeoff. Furthermore, this study contributes to the existing research base in this field and represents one of the pioneer attempts in the case of RNM. The results gained from the research are very important for companies themselves, but they can also serve as a starting point for future research to eliminate financial and other corporate issues related to the relationship between profitability and liquidity determinants.
Prevalência de úlcera por pressão em pacientes acamados, cadastrados na Estratégia de Saúde da Família: um estudo de enfermagem

Study described a quantitative approach, aimed to estimate the prevalence of pressure ulcers (UPP) and to investigate the sociodemographic, clinical and risk for injury in bedridden patients under home care at the Family Health Strategy in Teresina. We evaluated 30 patients, aged between 18 to 108 years, 80% elderly, 76.7% female, 70% mixed ethnicity, 86.7% were illiterate, 44.90% 20.41% hypertension and diabetes. 50% of patients bedridden due to degenerative diseases, 59.99% were at risk for UPP. The prevalence of UPP was 13.33% and 40% of stage I, and the anatomical regions of highest incidence were: coccygeal sacral (70%), malleolus, and trochanter, both with 25%. Whereas the majority of elderly and low socio economic UPP prevalence was lower than that found in studies at home, although most present high risk for development of UPP.

LTCS–Report Using model theory to ﬁnd ω -admissible concrete domains

Concrete domains have been introduced in the area of Description Logic to enable reference to concrete objects (such as numbers) and predeﬁned predicates on these objects (such as numerical comparisons) when deﬁning concepts. Unfortunately, in the presence of general concept inclusions (GCIs), which are supported by all modern DL systems, adding concrete domains may easily lead to undecidability. One contribution of this paper is to strengthen the existing undecidability results further by showing that concrete domains even weaker than the ones considered in the previous proofs may cause undecidability. To regain decidability in the presence of GCIs, quite strong restrictions, in sum called ω -admissiblity, need to be imposed on the concrete domain. On the one hand, we generalize the notion of ω -admissiblity from concrete domains with only binary predicates to concrete domains with predicates of arbitrary arity. On the other hand, we relate ω -admissiblity to well-known notions from model theory. In particular, we show that ﬁnitely bounded, homogeneous structures yield ω -admissible concrete domains. This allows us to show ω -admissibility of concrete domains using existing results from model theory.
Sociodemographic influences on Australian urban water practitioners’ risk perceptions towards stormwater harvesting and quality treatment systems

Risk assessment of traditional stormwater systems has focused on flooding issues but, for stormwater harvesting and quality treatment systems, risk management is likely to involve a broader range of risks. Although risk perceptions are acknowledged in ranking management priorities, covert risk perceptions need to be understood to allow critical reflection on their wider influence in risk management activities and their outcomes. However, risk perceptions might not be shared amongst practitioners but vary with such personal and professional attributes as field of study or organisational affiliation. Thus, this study explores the influence of various sociodemographic attributes on water practitioners’ risk perceptions of stormwater harvesting and quality treatment systems. Analysis of risk perception data collected from Australian urban water practitioners (N=620) in a national on-line survey revealed that a practitioner’s work area, stakeholder group and/or primary qualification can influence perceptions of general risk of stormwater harvesting systems, of specific risks that might be associated with stormwater harvesting and treatment systems, i.e. environmental risk, flooding risk, aesthetic risk, technological risk, public health risk, political risk and risk of loss of reputation, and of risk of drinking or showering with treated stormwater. These different risk perceptions are likely to be unacknowledged in urban water management but could contribute to reluctance by some to implement alternative urban stormwater systems.
Pilot Design for BEM-Based Channel Estimation in Doubly Selective Channel

This paper investigates pilot design for enhanced channel estimation in single carrier communication systems over doubly-selective channels (DSC). Our contribution is twofold: first, we propose to use Huffman sequences as pilot clusters with low peak-to-average power ratio (PAPR), yet with good channel estimation performance when periodic pilot placement is adopted; second, we propose a low-complexity pilot placement strategy based on the analysis of the complex-exponential basis expansion model (CE-BEM) of the DSC. The latter leads to improved channel estimation performance with useful insights for pilot placement.
An empirical study on the perceived fairness of realistic, imperfect machine learning models

There are many competing definitions of what statistical properties make a machine learning model fair. Unfortunately, research has shown that some key properties are mutually exclusive. Realistic models are thus necessarily imperfect, choosing one side of a trade-off or the other. To gauge perceptions of the fairness of such realistic, imperfect models, we conducted a between-subjects experiment with 502 Mechanical Turk workers. Each participant compared two models for deciding whether to grant bail to criminal defendants. The first model equalized one potentially desirable model property, with the other property varying across racial groups. The second model did the opposite. We tested pairwise trade-offs between the following four properties: accuracy; false positive rate; outcomes; and the consideration of race. We also varied which racial group the model disadvantaged. We observed a preference among participants for equalizing the false positive rate between groups over equalizing accuracy. Nonetheless, no preferences were overwhelming, and both sides of each trade-off we tested were strongly preferred by a non-trivial fraction of participants. We observed nuanced distinctions between participants considering a model "unbiased" and considering it "fair. " Furthermore, even when a model within a trade-off pair was seen as fair and unbiased by a majority of participants, we did not observe consensus that a machine learning model was preferable to a human judge. Our results highlight challenges for building machine learning models that are perceived as fair and broadly acceptable in realistic situations.
