Estrategia metodológica de la enseñanza de la programación para la permanencia de los alumnos de primer año de Ingenieria Electrónica

espanolLa programacion es una disciplina de las Ciencias de la Computacion con muchas aplicaciones, incluyendo problemas no triviales cuya resolucion constituye un desafio intelectual. La verdadera dificultad no reside en expresar la solucion del problema en terminos de instrucciones elementales de un lenguaje de programacion especifico, sino en la resolucion del problema propiamente dicha. El proceso de encontrar una solucion adecuada a un problema provoca en el alumno un conflicto cognitivo pues no dispone de un sistema de estrategias que le permitan responder de manera satisfactoria. Del analisis de la realidad aulica que se viene presentando con los alumnos ingresantes a la carrera de Ingenieria, se ha detectado que el rendimiento academico de los estudiantes es cada vez menos satisfactorio sumado a la complejidad propia de los contenidos de la asignaturaEn este trabajo se presenta la experiencia realizada durante el dictado del primer curso de programacion que reciben los alumnos de primer ano en la carrera de Ingenieria Electronica de la Facultad de Ciencias Fisico-Matematicas y Naturales, de la Universidad Nacional de San Luis. EnglishProgramming is a computer science discipline that has many applications in the real world including the resolution of nontrivial problems that involve great intellectual challenge. The main difficulty lies not in expressing the solution in terms of elementary instructions, but in solving the problem.

Owner attitudes and dog behaviour problems

In the treatment of dog behaviour problems, assessment of the owner's attitude is usually an essential part of the diagnostic process. Questionnaire studies of groups of owners reveal wide variation in both degree and kind of owner attachment. Individual-centred methods such as the Kelly Repertory Grid demonstrate the complexity of such attachments. It is suggested that the psychoanalytic concept of projection can often best explain their irrational aspects: experimental evidence is adduced and clinical examples discussed. With regard to particular types of behaviour problems, there is evidence of an association between dominance aggression in the dog and the anthropomorphic involvement of the owner; also between over-excitement and displacement activities in the dog and anxiety in the owner. Owner anxiety is not associated with a higher incidence of phobias in the dog; a dog's phobia, however, does tend to cause greater distress to a more anxious owner.
Stability Analysis of 2D Discrete Linear System Described by the Fornasini-Marchesini Second Model with Actuator Saturation

This paper proposes a novel antiwindup controller for 2D discrete linear systems with saturating controls in Fornasini-Marchesini second local state space (FMSLSS) setting. A Lyapunov-based method to design an antiwindup gain of 2D discrete systems with saturating controls is established. Stability conditions allowing the design of antiwindup loops, in both local and global contexts have been derived. Numerical examples are provided to illustrate the applicability of the proposed method.
Graft Engineering and Adoptive Immunotherapy: New Approaches to Promote Immune Tolerance After Hematopoietic Stem Cell Transplantation

Allogeneic hematopoietic stem cell transplantation (HSCT) is a curative therapeutic option for a wide range of immune and hematologic malignant and non-malignant disorders. Once transplanted, allogeneic cells have to support myeloid repopulation and immunological reconstitution, but also need to become tolerant to the host via central or peripheral mechanisms to achieve the desired therapeutic effect. Peripheral tolerance after allogeneic HSCT may be achieved by several mechanisms, though blocking alloreactivity to the host human leukocyte antigens while preserving immune responses to pathogens and tumor antigens remains a challenge. Recently uncovered evidence on the mechanisms of post-HSCT immune reconstitution and tolerance in transplanted patients has allowed for the development of novel cell-based therapeutic approaches. These therapies are aimed at inducing long-term peripheral tolerance and reducing the risk of graft-vs-host disease (GvHD), while sparing the graft-vs-leukemia (GvL) effect. Thus, ensuring effective long term remission in hematologic malignancies. Today, haploidentical stem cell transplants have become a widely used treatment for patients with hematological malignancies. A myriad of ex vivo and in vivo T-cell depletion strategies have been adopted, with the goal of preventing GvHD while preserving GvL in the context of immunogenetic disparity. αβ T-cell/CD19 B-cell depletion techniques, in particular, has gained significant momentum, because of the high rate of leukemia-free survival and the low risk of severe GvHD. Despite progress, better treatments are still needed in a portion of patients to further reduce the incidence of relapse and achieve long-term tolerance. Current post-HSCT cell therapy approaches designed to induce tolerance and minimizing GvHD occurrence include the use of (i) γδ T cells, (ii) regulatory Type 1 T (Tr1) cells, and (iii) engineered FOXP3+ regulatory T cells. Future protocols may include post-HSCT infusion of allogeneic effector or regulatory T cells engineered with a chimeric antigen receptor (CAR). In the present review, we describe the most recent advances in graft engineering and post-HSCT adoptive immunotherapy.
IRNSS Satellite Parameter Estimation using Combination Strategy

Indian regional Navigation Satellite system (IRNSS) is going to be an independent, indigenous navigation satellite system fully controlled by India, planned by ISRO. A system was designed of regional navigation satellite constellation, as an alternate to GPS constellation, for providing space based navigation support to various land, sea and air navigation users over the Indian region. The proposed IRNSS constellation consists of 7 satellites (3 in GEO and 4 in inclined GSO with 29 deg inclination). The continuous visibility of GEO and GSO satellites for near-equator regions provides a promising alternative for regional navigation. The Signal In Space (SIS) broadcasts satellite ephemeris in quasi keplarian elements and satellite clock coefficients which forms the primary navigation parameters generated from navigation software located at INC (ISRO Navigation Centre), bylalu, India. The determination of these parameters is performed by two types of technique, batch least square (BLS) and Extended Kalman Filter (EKF).
Knowledge exchange roles and EKR performance impact: extending the theory of knowledge reuse

Abstract Organisations are spending considerable resources on electronic knowledge repositories (EKRs) that should have a positive effect on employees’ EKR performance impact. Seeking to build on and extend the theory of knowledge reuse, this paper focuses on the various roles individuals play in knowledge exchange, and how the knowledge exchange role mediates the effect of previously studied individual perceptual variables (perceived time pressure, extrinsic and intrinsic rewards, and knowledge contribution self-efficacy) on EKR performance impact. In order to identify the various knowledge exchange roles, we simultaneously consider both knowledge contribution process (embedded vs. separate activity) and knowledge reuse (internal EKR, external EKR, colleagues, manuals, knowledge self-reliance). When work is highly specialised and technical as in the context of system administrators, we observed four roles: Self-reliant Contributors, Detached Moderates, Involved Brokers, and Reluctant Limited Users. Results indicate that the effects of intrinsic rewards and knowledge contribution self-efficacy on EKR performance impact are fully mediated by knowledge exchange role. Perceived time pressure does not influence either knowledge exchange roles or EKR performance impact. Overall, the paper provides insights into roles individuals play in knowledge exchange, and extends the theory of knowledge reuse.
Influences of isomeric butanol addition on anti-knock tendency of primary reference fuel and toluene primary reference fuel gasoline surrogates

The anti-knock tendency of blends of butanol isomers and two gasoline surrogates (primary reference fuels and toluene primary reference fuels) was studied on a single-cylinder cooperative fuel research engine. The effects of butanol molecular structure (n-butanol, i-butanol, s-butanol and t-butanol) and butanol addition percentage on fuel research octane numbers were investigated. The experimental results revealed that butanol addition to either PRF80 or TPRF80 increased research octane numbers, and the research octane numbers of fuel blends showed higher linearity with the molar percentage than with the volumetric percentage of butanol addition. Furthermore, the research octane number boosting effects of butanol isomers were observed to change with the fuel compositions, that is, i-butanol >s-butanol >n-butanol >t-butanol for primary reference fuels and i-butanol >s-butanol >t-butanol >n-butanol for toluene primary reference fuels. In addition, butanol/primary reference fuel blends exhibited higher research octane numbers than butanol/toluene primary reference fuel blends. We thereafter tried to elucidate the underlying fuel combustion kinetics for the observed anti-knock quality of different butanol/gasoline surrogate blends. It was found that the measured research octane numbers of fuel blends showed the best correlation with the calculated ignition delay times at the thermodynamic condition of 770 K and 2 MPa, and the reaction sensitivity analysis in auto-ignition at this condition revealed that the H-abstraction reactions of butanol isomers by OH radical suppressed fuel reactivity, thus elevating the fuel research octane numbers when butanol was added to the gasoline surrogates. Compared with the butanol/primary reference fuel blends, the positive sensitive reactions related to n-heptane were of higher importance, while the inhibitive effects of sensitive reactions related to butanol and iso-octane decreased for the toluene primary reference fuel/butanol blends, thus leading to lower research octane numbers of the toluene primary reference fuel/butanol blends than those of the butanol/primary reference fuel blends.
Barriers in Reporting Medication Administration Errors as Perceived by Nurses in Saudi Arabia

Patient safety continues to be threatened because of medication administration errors (MAEs). This study aimed to assess why medication administration errors are not reported as perceived by nurses in a large government-owned tertiary hospital in Saudi Arabia. A cross-sectional survey was conducted among 307 nurses assigned to various service units. Data were analyzed using SPSS v.17 software. The results indicated that nurses in this setting perceived administrative response (M=4.04) as a factor why medication administration errors were not reported. Blaming (M=4.2) and focusing on the individual rather than looking at the systems as potential cause of error (M=4.12) were the top two perceived reasons why medication administration errors were not reported. More than half of the nurses (181/307; 58.96%) reported actual errors between 0% and 20% suggesting that there is under-reporting. Not reporting actual medication administration errors is a complicated issue that involves nurses' paradigm, leadership style and organizational culture as evidenced in this study. Further studies are needed in order to understand and find out what really are the underlying reasons why medication administration errors are not reported. Individual, Administration, organizational and cultural peculiarities are needed to be considered in formulating organization-specific strategies to address non-reporting of medication administration errors that will result in improved patient safety.
Development and Launch of a Comprehensive Fish and Wildlife Reporting Mobile Application

This paper describes the conception, development, launch, marketing, and maintenance of the Florida Fish & Wildlife Conservation Commission Reporter (FWC Reporter), a mobile application (app) that the public can use to report fish and wildlife and environmental concerns to appropriate state agency offices. The FWC Reporter, launched in February 2018, is the first comprehensive reporting app developed by a fish and wildlife agency in the United States that we are aware of. On the basis of a consumer concept test and library research, the app's design incorporates elements of fast and frugal heuristics and inductive decision theory. The FWC developed this version of the app in-house with an open-source development package, and involves primarily email and telephone to send reports and facilitate communication with agency staff. From February 2018 through December 31, 2018, the FWC recorded over 1,000 downloads on Android and 4,308 on Apple devices, and 258 emailed reports. Since fish and wildlife reporting apps do not provide clear benefit to the user (low value proposition), it is crucial that offices receiving reports are proactive in building and maintaining their own reporting constituency. Engagement with the public is not only through active recruitment of app users, but also following up after a report is made so that the users know their efforts are appreciated. Two FWC programs demonstrated successful engagement, horseshoe crabs Limulus polyphemus and fish kills, as they received the most email reports. Other topics for any conservation or fish and wildlife agency to consider when developing their own reporting mobile app include download intention, adoption, continuance, habit formation, public and organizational acceptance, and marketing.
Mathematical studies of a mechanobiochemical model for 3D cellmigration

This work presents the development, analysis and numerical simulations of a model for cell deformation and movement, which couples biochemical reactions and biomechanical forces. The way that cells move is key to the creation and development of most organisms on earth. Consequently a deeper understanding of cell motility is likely to have significant applications to medicine. We propose a mechanobiochemical model which considers the actin filament network as a viscoelastic and contractile gel. The mechanical properties are modelled with a force balancing equation for the displacement. The pressure and contractile forces are influenced by actin and myosin and we model these with a system of reaction-diffusion equations. The model consists of highly non-linear partial differential equations. To analyse the model, we carry out linear stability analysis to determine key bifurcation parameters and find analytical solutions close to bifurcation points. We then approximate the equations and produce numerical solutions in multi-dimensions, using an evolving finite element method. The solutions predicted from linear stability theory are replicated in the early stages of cell movement. Subsequently, both simple and complex deformations, such as expansions, protrusions, contractions and translations of the cell are observed. This theoretical and computational framework allows the study of more complex and experimentally driven reaction kinetics involving, actin, myosin and other molecular species that play an important role in cell movement and deformation.
Cocaine content and adulterants in street samples seized in the city of S. Paulo, Brazil.

Street cocaine samples (233) seized in the ilegal market of the city of S. Paulo, SP, Brazil were examined. Both cocaine content and the presence of pharmacological active adulterants were determined for each sample. Adulterants were found in only ten samples: lidocaine (8) and procaine (2). Cocaine contents varied from 10 to 964.2 mg/g of powder; 76.82 per cent of the samples analyzed were constituted by no more than 300 mg/g and only 3.86 per cent had more than 800 mg/g of cocaine
Blind Star Identification Algorithm

In this paper, a new algorithm called blind star identification is presented to identify the stars in night sky images without using the intrinsic parameters of the star sensor camera (focal length, principal point, and pixel size), and in lost in space mode. The accuracy and reliability of the proposed algorithm were successfully validated by using the real night sky images and Monte Carlo simulations. Accordingly, the proposed algorithm was successfully able to identify in more than 90% of the images containing more than five stars and no wrong identification was observed in the Monte Carlo simulations. On the other hand, the rotation around the optical axis, which cannot be estimated using vector observations, should be minimized in the process of designing and manufacturing the star sensor and carefully measured in the ground calibration, like as the aberration and lens distortion. Ultimately, another advantage of this algorithm is the simultaneous use of planar and interstellar angles. This advantage leads to data redundancy and greater reliability of the algorithm so that the performance of the algorithm is guaranteed under severe error conditions.

Keris and Other Malay Weapons

A keris (or kris) is a unique knife or sword that has been constructed for magical as well as practical purpose. Its creation is a long and complicated ritual in which magical ingredients are blended with the metal and a powerful jinn ('genie') spirit is invoked into the blade. After the keris has been created, the spirit is continually fed, so it gradually grows more powerful. They are often passed down from generation to generation: the oldest examples go back to the 8th century, and are considered extremely potent. A new edition of a classic on Malay weaponry and war originally published in 1936, and now virtually impossible to find. In this work, Gardner illustrates (photos & drawings), describes and catalogues the entire corpus of Malay weaponry. He pays close attention to the origins of the Kris and its close association with the Occult in Malaya - an interest that was to have a huge affect upon him later in life. On return to England, he focussed all his energies on the study of Western witchcraft and the occult, and is considered by many to be the Father of the modern Wicca movement.
Factors Affecting the Dry Period Length and Its Effect on Milk Production and Composition in Subsequent Lactation of Holstein Cows

The study aimed to determine factors affecting the dry period length and effect of dry days on milk yield, milk composition and lactation length in the next lactation of dairy cows. Data used for analysis included 7264 lactation records collected from 2012 to 2016 on 4737 Holstein cows raised in 152 herds. The statistical model used to determine the factors influencing the dry period length showed that multiparous cows had a dry period 3.7 days longer than primiparous cows, and cows that calved from October to February had a dry period 2.5 days shorter than that of cows calved from March to September. The mixed model used to evaluate the influence of dry period on milk yield, milk composition and lactation length showed that the dry period influenced significantly milk yield and composition in the next 305 d lactation, but not the lactation length (P>0.05). Milk, fat and protein yields in the subsequent lactation were maximized with a 41 to 60-d dry period, whereas dry periods less than 20 d result in very pronounced losses in subsequent lactation yield. Fat and protein percentages were highest with the dry period classes greater than 80-d and less or equal than 20 d, respectively. The interaction between parity and dry length period was not significant (P>0.05) for any studied trait, indicating that dry days effects on milk yield and composition were consistent across lactations. It was concluded that dry period of 40 to 80 dry days does provide maximal performance in Holstein cows.
Multicenter questionnaires on the current management of atopic dermatitis in Korea

Purpose: The effective management of atopic dermatitis (AD) adjusted to individual clinical courses and demands can be challenging to both patients and physicians. Understanding of actual situations, experienced and perceived by patients with AD and their caregivers, is essential to improve clinical outcomes and satisfaction in real practice.Methods: This multicenter survey was conducted in patients with AD or their caregivers from 9 centers with questionnaires on diagnosis and management of AD.Results: A total of 324 patients and caregivers participated in the study. Most of the AD cases were initially diagnosed by physicians (80.6%), followed by self-diagnosis. Patients and caregivers thought that allergic substances, such as house dust mites, food, and pollutants, are responsible for AD development; moisturization, environmental control, and improvement of the body constitution are important for AD management. Allergy tests were performed in 194 patients (59.9%), but allergen avoidance strategy was instructed in only 81 subjects (41.8%). Major topical medications were steroids (81.8%) and topical immunomodulators (34.3%), while systemic medications were steroids (42.6%), antihistamines (36.4%), and cyclosporins (2.8%). One hundred eighty-one subjects (55.9%) had received complementary alternative medicine, including Oriental medicine. Many subjects desired to receive individualized management, use of specialized institutions for AD as well as evidence-based, effective, sustainable treatment.Conclusion: Our findings suggest that there may still be an unmet need for patients with AD in real practice. Personalized, evidence-based, and multidisciplinary approaches, including patient education, should be implemented for good outcomes. (Allergy Asthma Respir Dis 2016:4:271-275)
