Research on satellite selection algorithm in ship positioning based on both geometry and geometric dilution of precision contribution
Authors: Zhang Pengfei
Published: February 2019

With the networking of four Global Navigation Satellite Systems, the combination of multi-constellation applications has become an inevitable trend, and there will be more and more visible satellites that can be participated in ship positioning. However, the computational complexity increases sharply, which greatly improves the load capacity of the receiver’s data processor and reduces the output frequency of the positioning result. To achieve the balance between positioning accuracy and computational complexity, a new fast satellite selection algorithm based on both of geometry and geometric dilution of precision contribution is proposed. Firstly, this article analyzes the geometry characteristics of the least visible satellites has minimum geometric dilution of precision that meet the positioning requirements and makes clear the layout of their elevation angles and azimuth angles. In addition, it derives the relationship of geometric dilution of precision and the visible satellites layout and gets geometric dilution of precision contribution of each satellite. Finally, based on the observation data of JFNG tracking station of the Multi-Global Navigation Satellite System (GNSS) Experiment trial network, the positioning error and the elapsed time of GPS/Beidou Satellite Navigation System and GPS/Beidou Satellite Navigation System/Russian Global Orbiting Navigation Satellite System (GLOANSS) are compared. Simulation results show that the algorithm solves the problem that there are a lot of matrix multiplications and matrix inversions in the traditional satellite selection algorithm, and the new algorithm can reduce computational complexity and increase receiver processing speed.
Retinal Artery Occlusion in Young Patients: A 6-Year Review
Authors: Xia Tian , Zarbin Marco A. , Bhagat Neelakshi
Published: February 2019

Purpose:

This article describes the characteristics, management, and etiology of retinal artery occlusions (RAOs) in young patients.

Methods:

A retrospective chart review of patients <50 years of age with ophthalmic and RAOs was conducted. Data were collected on demographics, clinical presentation, laboratory and imaging evaluation, management, and outcome.

Results:

Seventeen eyes of 15 patients younger than 50 (mean age, 34±8 years; 71% male, 29% female) with RAOs were identified. AOs included: 8 (47%) central RAOs (CRAOs), 5 (29%) branch RAOs (BRAOs), 3 (18%) ophthalmic AOs (OAOs), and 1 (6%) combined CRAO and vein occlusion (CRAO/CRVO). Logarithm of the minimum angle of resolution visual acuity (VA) at presentation was 2.6±4 (Snellen range 20/15 to no light perception). Systemic diseases in patients with BRAO included Susac disease (n = 1), sickle cell disease (n = 2), patent foramen ovale (PFO) (n = 1), and HIV (n = 1). CRAO was diagnosed in 4 patients after invasive surgery (3 after neurosurgery and 1 after cardiac surgery). Other patients had hypertension (n = 3), hypercoagulability due to uterine cancer (n = 1), and PFO (n = 1). OAOs were noted in 1 patient with Saturday night retinopathy and in 1 with ruptured internal carotid aneurysm at the level of the ophthalmic artery. Two eyes with CRAO were treated with tissue plasminogen activator (1 intraophthalmic artery through catheterization and 1 intravenously) without any change in final VA. In these patients, VA remained poor (VA hand motions – counting fingers) at 6 months or greater follow-up visits.

Conclusion:

RAO in young patients is uncommon. In this series, one-fourth of occlusions were seen during the perioperative period. A significant number of patients had concurrent uncontrolled hypertension. Other associated systemic findings included PFO, hypercoagulability, sickle cell disease, Susac disease, and HIV.

PURPOSE

To provide resource-stratified, evidence-based recommendations on the treatment and follow-up of patients with early-stage colorectal cancer.

METHODS

ASCO convened a multidisciplinary, multinational Expert Panel that reviewed existing guidelines and conducted a modified ADAPTE process and a formal consensus process with additional experts for one round of formal ratings.

RESULTS

Existing sets of guidelines from 12 guideline developers were identified and reviewed; adapted recommendations from six guidelines form the evidence base and provide evidence to inform the formal consensus process, which resulted in agreement of 75% or more on all recommendations.

RECOMMENDATIONS

For nonmaximal settings, the recommended treatments for colon cancer stages nonobstructing, I-IIA: in basic and limited, open resection; in enhanced, adequately trained surgeons and laparoscopic or minimally invasive surgery, unless contraindicated. Treatments for IIB-IIC: in basic and limited, open en bloc resection following standard oncologic principles, if not possible, transfer to higher-level facility; in emergency, limit to life-saving procedures; in enhanced, laparoscopic en bloc resection, if not possible, then open. Treatments for obstructing, IIB-IIC: in basic, resection and/or diversion; in limited or enhanced, emergency surgical resection. Treatment for IIB-IIC with left-sided: in enhanced, may place colonic stent. Treatment for T4N0/T3N0 high-risk features or stage II high-risk obstructing: in enhanced, may offer adjuvant chemotherapy. Treatment for rectal cancer cT1N0 and cT2n0: in basic, limited, or enhanced, total mesorectal excision principles. Treatment for cT3n0: in basic and limited, total mesorectal excision, if not, diversion. Treatment for high-risk patients who did not receive neoadjuvant chemotherapy: in basic, limited, or enhanced, may offer adjuvant therapy. Treatment for resectable cT3N0 rectal cancer: in enhanced, base neoadjuvant chemotherapy on preoperative factors. For post-treatment surveillance, a combination of medical history, physical examination, carcinoembryonic antigen testing, imaging, and endoscopy is performed. Frequency depends on setting. Maximal setting recommendations are in the guideline. Additional information can be found at www.asco.org/resource-stratified-guidelines .

NOTICE

It is the view of the American Society of Clinical Oncology that health care providers and health care system decision makers should be guided by the recommendations for the highest stratum of resources available. The guidelines are intended to complement but not replace local guidelines.
Death Wish
Authors: Huneke Samuel Clowes
Published: February 2019

This article analyzes the relationship between suicide and homosexual discourses in modern Germany. Considering literature, gay periodicals, mainstream newspapers, letters, plays, and poetry, it asks how authors came to correlate homosexuality so strongly with a propensity to commit suicide. In particular, the article makes out a dialectical relationship among three discursive tropes of gay suicide. Doctors and activists of the nineteenth century, including the sexologist Magnus Hirschfeld, employed gay suicide to call for the abolition of Germany’s ban on male sodomy. In opposition thereto, masculinist writers depicted gay suicide sympathetically. Weimar-era literature synthesized these diametric trends into a ubiquitous narrative of gay suicide, which would color mainstream representations of homosexuality and perpetuate the stereotype that gay people are destined to have tragic lives of misery and self-inflicted death. This article argues that the suicide stereotype played a significant role in the formation of modern gay discourses and that its influence remains strong even today.
Sunlit Dancers
Authors: Satterthwaite Tim
Published: February 2019

The German photo-illustrated magazine UHU, launched in 1924, was known for its risqué photography of the female nude. These photos offered, however, more than mere titillation: images of pastoral nudes, and of naked dancers, were a sublime expression of UHU’s cult of youth and physicality and of visual beauty in the natural and manmade world. Significantly, the magazine’s eclectic visual culture—which also embraced images of male gymnastics and of children—inflected the ideological conflicts that centered on the unclothed body in this period. The article describes how contrasting ideas of the body, and of social order, are symbolically expressed in poses and pictorial settings. In particular, the grouping of figures, in geometric and informal “human patterns,” speaks to a fundamental dichotomy in Weimar modernism: the divide between machine-based (rationalist) ideologies and “spiritualized” visions of an organic social order. UHU’s sunbathers and expressive dancers embodied the dynamic tensions of the new technological society—tensions that would resolve, with drastic consequences, in the following decade.

Published: February 2019

A novel selective and sensitive chemosensor, (E)-1-((((1H-benzo[d]imidazol-2-yl)methyl)imino)methyl)naphthalen-2-ol (BIN), was developed for fluorescence detection of Zn2+. The compound BIN acts as a fluorescent “turn-on” detector for Zn2+. The limit of detection (2.26 µM) for zinc ion is well below the WHO standard (76.0 µM). Probe BIN can be chemically reversible with ethylenediaminetetraacetic acid (EDTA). The binding mechanism of BIN with zinc ion was demonstrated by fluorescence, UV-visible, electrospray ionization mass spectroscopy, 1H NMR titration and calculations. Importantly, probe BIN could be applied to determine zinc ion in water samples and living zebrafish.
Selective Extraction of Zr(IV) over Hf(IV) from Aqueous Hydrochloric Acid with p-tert-Butylcalix[4]arenediphosphonic Acid
Authors: Morohashi Naoya , Kato Yutaka , Sumida Sahoko , Kurusu Yu , Hattori Tetsutaro
Published: February 2019

p-tert-Butylcalix[4]arenediphosphonic acid (L) extracts Zr(IV) and Hf(IV) from aqueous HCl, H2SO4, and H3PO4. In the extraction from aqueous HCl of different concentrations, the percentage of extraction (E%) of Hf(IV) decreases notably with an increase in acid concentration (96% at 0.5 M HCl and 12% at 7 M HCl), whereas the E% of Zr(IV) remains at a moderate level (90% at 0.5 M HCl and ∼60% at 7 M HCl). Thus, selective extraction of Zr(IV) over Hf(IV) is achieved from high-concentration HCl solutions. The separation factor (SZr) reaches 24 when using two molar equiv of L to Zr(IV) at 7 M HCl. Mechanistic studies indicate that L extracts Zr(IV) from high-concentration HCl solutions by a solvation mechanism by forming a 1:1 complex, LZrCl4. Back extraction of Zr(IV) proceeds quantitatively by treating the organic phase with 5 M H3PO4 after the extraction of Zr(IV).

Published: February 2019

India has an estimated 12 million people affected with glaucoma; however, no organised screening programme exists. Cases are usually detected opportunistically. This study documents the protocol for detecting glaucoma in suspects in cataract camps conducted by Shroff Charity Eye Hospital in North India. We report a prospective study design from patients attending cataract camps where glaucoma screening will be integrated. The eligible population for glaucoma screening is non-cataract patients. Patients will undergo glaucoma screening by a trained optometrist using a pre-determined glaucoma screening algorithm. Specific diagnostic cut-off points will be used to identify glaucoma suspects. Suspected patients will be referred to the main hospital for confirmatory diagnosis and treatment. This group will be compared to a cohort of patients arriving from cataract camps conducted by the institute in similar areas and undergoing examination in the hospital. The third arm of the study includes patients arriving directly to the hospital for the first time. Cost data will be captured from both the screening components of cataract-only and glaucoma screening-integrated camps for screening invitation and screening costs. For all three arms, examination and treatment costs will be captured using bottom-up costing methods at the hospital. Detection rates will be calculated by dividing the number of new cases identified during the study by total number of cases examined. Median, average and range of costs across the three arms will be calculated for cost comparisons. Finally, cost-effectiveness analysis will be conducted comparing cost per case detected across the three arms.This is the first such study conducted in India. The study protocol will be useful for researchers and practitioners for conducting similar economic evaluation studies in their context. The protocol publication will be a good step to ensure transparency of methods of reporting of economic evaluation studies in LMICs.
Using a Monte Carlo Simulation Exercise to Teach Principles of Distribution: An Enhanced Version of the Classic Transportation Problem
Authors: Weltman David , Tokar Travis
Published: February 2019

This paper explains a Monte Carlo simulation workshop applied to an extended version of the classic transportation problem. It is designed to be conducted in a classroom or laboratory where students have access to a Monte Carlo simulation tool, such as Oracle Crystal Ball. The hands-on exercise builds on the classic transportation problem by allowing students to develop cost-efficient solutions when demands are uncertain and follow multiple types of patterns. Students develop a distribution plan by considering transportation, inventory-holding, and stock-out costs. Through simulation, students are able to see the consequences of their proposed policies and revise them until reaching a satisfactory solution. The Monte Carlo method is deployed because traditional deterministic optimization models do not exist for our scenario that we believe to be realistic and widely applicable. Students gain valuable experience using an important modeling tool applied to a classic operations-management problem.

Oral and dental management for people with lymphoma
Authors: Abed Hassan , Nizarali Najla , Burke Mary
Published: February 2019

Abstract: A lymphoma is a solid neoplasm that arises in lymphoid tissues and spreads to distant lymphoid glands and organs. Functional lymphocytes circulate the body in the lymphatic system as a part of the immune system. In lymphoma, proliferated abnormal lymphocytes collect in the lymphatic glands and organs with variant signs and symptoms based on the affected site. There are two main types of lymphoma: Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL), with different subtypes. The major aetiology is still unknown. Varying treatment modalities are available including monoclonal antibodies, chemotherapy, radiotherapy, corticosteroids and haematopoietic stem cell transplant (HSCT). These have acute and longer-term side-effects that affect clinical decision-making for dental treatment. Therefore, people with lymphoma benefit from a pre-treatment dental assessment and should have regular follow-up in primary care.

CPD/Clinical Relevance: This paper aims to provide dental care providers in the primary care setting, community dental service or hospital dental setting with knowledge to manage patients diagnosed with lymphoma.
A case of florid pregnancy gingivitis
Authors: Hua Lewis , Locke Matthew
Published: February 2019

Abstract: The aim of this case is to demonstrate an exaggerated appearance and subsequent management of a florid combination of pregnancy gingivitis and multiple pregnancy epulides. Pregnancy-associated periodontal conditions constitute benign overgrowth that histologically may be indistinguishable from pyogenic granulomata. The literature has described presentation from the first trimester, peaking in the third trimester before an amount of spontaneous resolution post-partum. This paper describes a 26-year-old woman at 33 weeks of gestation who was referred for significant generalized enlarged gingivae with accompanying soreness and discomfort in oral function. Florid gingivitis and epulis represents important periodontal manifestations during pregnancy and can be troublesome in providing meaningful immediate pain relief.

CPD/Clinical Relevance: The dental clinician should be aware of pregnancy-associated gingivitis/epulis, the aetiology, presentation and be able to provide necessary steps for diagnosis, treatment and referral pathways in the primary care setting. These lesions should always be included in the differential diagnosis of oral mucosal soft tissue masses.

Published: February 2019

The light source in tissue culture is often one of the punctual factors for the adequacy of plant production. For this, light emitting diodes (LEDs) have been used in order to increase the growth and development of the plants propagated in vitro. The objective was to evaluate the in vitro propagation of cultivars of Alpinia purpurata ‘Red Ginger’ and ‘Pink Ginger’ in two different light sources (fluorescent or LEDs tubes). The experiment was conducted in a completely randomized design, factorial scheme (2x2), totaling four treatments with ten replicates, and the experimental unit composed of one flask containing five explants. After 55 days, white LED and the ‘Red Ginger’ provided the highest number of shoots. For the number of leaves, the cultivar ‘Red Ginger’ and white LED lamps provided superior results. For shoot length (cm), the cultivar ‘Red Ginger’ kept under fluorescent lamps was superior, and ‘Pink Ginger’ presented superiority when cultivated under LED lights. Thus, even with differentiated responses among genotypes, the use of white LED lamps in the in vitro propagation of Alpinia purpurata ‘Red Ginger’ and ‘Pink Ginger’ cultivars is suggested.
Is the Measles Virus Indeed Involved in Carcinogenesis? – Commentary
Authors: Benharroch Daniel
Published: February 2019

Objectives:
An association between the measles virus and Hodgkin lymphoma has been disclosed by our laboratory in Beer-Sheva, starting in 2003. We question the refutation of our study and the absence of interest among experts.

Methodology:
It was based on immunohistochemistry with commercial, as well as experimental anti-measles antibodies. It relied also on RT-PCR and in situ hybridization evidence of measles virus RNA.

Key Results:
At this stage (2004), the link between the virus and the lymphoma was essentially descriptive. The first and last response to our challenge appeared in 2007, in the form of doublet articles, in the same issue of a major cancer journal. The two European research groups responding, rejected categorically our findings by proposing different arguments.

Major Conclusion:
As reservations to these reactions became soon apparent, a series of papers from our laboratory were published. These articles concerned the evidence of a relationship between the measles virus and additional categories of cancers. Different malignancies in which this virus was not expressed at all, were also described. A further study suggested a mechanism by which the measles virus may activate lymphomagenesis in classic Hodgkin lymphoma. To our dismay, and in spite of repeated calls to verify the various results, no further response was obtained from international experts.

The incremental contribution of social capital over psychological capital in explaining employees’ performance and wellbeing in the Indian Banking sector is explored. Data was collected from 101 clerical employees, using standardised questionnaires and they have adequate reliability coefficients. Data was analysed by hierarchical regression method. None of the demographics variables predicted any of the outcome variables. Self efficacy was the only psychological capital which emerged as the significant predictor of both performance and wellbeing. Bonding capital emerged as a significant predictor of job performance. Bridging capital caused a negative variance in both job performance and well being. Results were discussed in the light of existing theories and frameworks

Effect of Biological Rhythm on Cognitive Performance
Authors: Yadav Ravinder , Singh NP
Published: February 2019

Biological rhythm has contributed in evolution process of humankind and has created certain distinct capabilities and preferences in shaping his phycho-psychological reactions. On the basis of behavioural activities, reactions, preferences and performances during the day-night cycle, individuals are classified in chronotype as morning type (M type) and evening type (E type). Such a differentiation has been hypothesised to contributing to individual differences at the cognitive, affective and conative levels. The present study was an attempt to further study such differentiation in terms of neuro cognitive performance by using the most advanced psycho-physiological measures. The participants of both chronotypes, morning and evening were classified and later subjected to cognitive testing by using the Cambridge Neuropsychological Test Automated Battery in the morning and the evening session under repeated measure design. The study revealed that performance on neuro cognitive functions; Planning and working memory, Decision-making and response control, and Motor skills get effected differently by their biological rhythm cycle and thus under performance in these functions can be attributed to maladaptation of biological rhythm termed as biological dysrhythmia. The study also highlights the role of this behavioural maladaptation in moderating operational efficiency of soldier in combat situation.

Cell Permeabilisation, Microstructure and Quality of Dehydrated Apple Slices Treated with Pulsed Electric Field During Blanching
Authors: Chauhan Om Prakash , Shayanfar Shima , Topefl Stefan
Published: February 2019

ABSTRACTEffect of pulsed electric field as a blanching pretreatment on cell permeabilization, microstructure and quality of dehydrated apple slices was studied. Apple slices were pulsed electric field pretreated (1.0, 1.5 and 2.0 kV/cm using 25 and 75 pulses) at a temperature of 60 and 80°C in water followed by dehydration at 60°C in a cabinet dryer. Cell disintegration index was found to increase significantly (p<0.05) with increase in the electric field strength, number of pulses and blanching temperature and thereby reducing the drying time. The dehydrated slices showed lower hardness and higher lightness (L*) values for the samples treated at higher electric field strength for longer durations. Scanning electron microscopic studies of samples revealed better retention of cellular integrity when pre-treated at a low level of PEF (1.0 kV/cm using 25 pulses) and blanched at low temperature (60°C). However, the samples treated to a level of 1.5 kV/cm and 75 pulses of PEF with subsequent blanching temperature 80°C was found to yield optimum cell permeabilization. The study suggests that PEF can be used as an effective blanching pretreatment for achieve good quality dehydrated apple slices in less drying time.

Published: February 2019

Abstract Airborne fungi may cause a variety of health problems in human and animals. In this study, a survey of fungal bioaerosols was done for three years during 2007-2009 in Central India. Air samples were collected from four different locations at Gwalior, Central India on monthly basis. Results showed that fungal bioaerosols concentrationranged from 550 to 7363 CFU/m3 at different sites. Significant higher bioaerosols content was observed during the year 2008 and 2009 than 2007. Highest mean fungal concentration (2687.86 CFU/m3) was found at a public garden, whereas lowest mean concentration (1722.72 CFU/m3) was observed at civil hospital. A seasonal rhythm was observed in the level of airborne fungi. Maximal fungal count was observed in winter followed by monsoon and lowest in summers. Among meteorological factors, statistically significant negative correlation was found with temperature and wind speed. During the study, a total of 41 fungal species belonging to 21 genera were identified. Alternaria, Aspergillus, Cladosporium, Curvularia, Fusarium, Penicillium, Phoma and Trichothecium were the dominated genera. Several identified fungal species viz. Alternaria alternata, Aspergillus flavus, Aspergillus niger,Penicillium citrinum, Penicillium chrysogenum, Fusarium moniliforme, Trichoderma harzianum and Rhizopus stolonifer from the studied area are well known for causing allergy or production of mycotoxin.

Bacteriophages play an important role in bacterial control in natural niche however a little is known about Bacillus sp. phages prevailing in cadaver affected soils. In the current study, the Bacillus sp. phage was isolated from the equine cadaver disposal site and characterised to gain an insight into the issue of role of phages in biological dynamics of manure thus formed over years. Firstly, the host bacterium was isolated and identified as Bacillus cereus group member as assessed by phylogenetic analysis and secondly it’s corresponding phage from same soil sample was also enriched and characterised. The phage (VTCCBPA38) was found to belong to family Myoviridae and was active within the temperature range of 4°C - 45°C. As assessed by biological sensitivity by spot test, the phage was active against 6/19 (31.6 %) Bacilli tested including Bacillus cereus from goat mastitis. Thus the phagemay find potential use in biocontrol of diseases caused by Bacillus sp. Furthermore, this report is valuable as the first study for investigation of Bacillus sp. phage in carcass burial sites.

The current study was undertaken to determine the effect of HS on liver microstructure and function in rats. A heat simulation chamber with ambient temperature (Ta) 45 ± 0.5 °C and relative humidity (RH) 30 ± 5 per cent was used to expose animals to HS. Rats were categorised as moderately heat stressed (MHS, Tc = 40 °C) and severely heat stressed (SHS, Tc = 42 °C) group. We observed that with rise in core temperature (Tc) alanine aminotransferase(ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) levels were increased but glucose level was decreased in both plasma and liver tissue. Significantly elevated levels of reactive oxygen species (ROS) and nitric oxide (NO) were detected in liver of MHS and SHS animals. Additionally, glutathione disulfide and glutathione (GSSG and GSH) ratio was found to be increased with rise in Tc which suggested saturation in antioxidant capacity of tissue. Furthermore, levels of heat shock proteins (HSPs) and caspases were upregulated upon HS. Results of histological examination indicated extensive loss of cells in liver parenchyma leading to disorganisation of lobular structure. Thus, biochemical and histological studies in experimental animals demonstrates that HS may severely altered structural and biochemical functions of liver.

Experimental measurement of intense light induced refractive index is demonstrated using Fizeau interferometer. Refractive index is induced in a specific region of the sample with intense light pulse of a linearly polarized, Q- switched Nd:YAG laser at 1064nm wavelength. The respective change in optical path difference (OPD) is measured using Fizeau interferometer. The OPD so obtained is mapped in terms of change in refractive index in the area of interaction of pump beam and sample. The measured induced refractive index is then used to calculate thermo-optic coefficient of the ZnPc embedded polymeric sample.
Methodology for Integrating Computational Tree Logic Model Checking in Unified Modelling Language Artefacts A Case Study of an Embedded Controller
Authors: Kochaleema KH , Santhoshkumar G.
Published: February 2019

A unified modelling language (UML) based formal verification methodology that can be easily integrated into an embedded system software development life cycle is suggested. The approach augments UML diagrams with formal models through an interfacing domain and adds semantics to these diagrams. The suggested methodology; commences from functional specification and use case modelling, selects the most critical behaviour where formal verification can add value to the development cycle, analyses the selected behaviour using UML state transition diagram, derives a state chart matrix from the same, and a high level language software translates the state chart matrix to a labelled transition system. Safety properties are derived from system specifications and are expressed as computation tree logic (CTL) formulae. CTL model-checking algorithm from the literature is used for model- checking. The applicability of the suggested approach is established using a safety critical embedded controller used for deployment and recovery of sensor structures from an airborne platform.

In this study, a wideband circularly polarised (CP) antenna is developed and demonstrated. The antenna comprises of two-layered substrates, the top layer holds a driven patch and eight surrounding parasitic patches of similar dimensions, and substrate integrated waveguide (SIW) based feeding topology is designed at the bottom layer. The driven patch is excited through coupling mechanism using a cross-slot carved on the upper clad of the SIW. The corners of the driven patch are curtailed and arms of the coupling slot made unequal, which constructively generates the CP wave. Moreover, the proposed antenna is prototyped, and experimentally verified. The antenna shows measured impedance and axial-ratio (AR) bandwidths of 1.29 GHz (21 per cent) and 460 MHz (7.35 per cent), respectively, while maintaining the high gain of ~8 dBic over the operating CP region. This design aids the favorable characteristics such as light weight, wide impedance and (AR) bandwidths, high-gain as well as lenience of production, and integration.

Daniel Goleman, best known for his worldwide bestseller “Emotional Intelligence,” is most recently co-author of “Altered Traits: Science Reveals How Meditation Changes Your Mind, Brain and Body.” A meditator since his college days, Goleman has spent two years in India, first as a Harvard Predoctoral Traveling Fellow and then again on a Post-Doctoral Fellowship. Dr. Goleman’s first book, “The Meditative Mind: The Varieties of Meditative Experience,” is written on the basis of that research, offering an overview of various meditation paths. Goleman has moderated several Mind and Life dialogues between the Dalai Lama and scientists, ranging from topics such as “Emotions and Health” to “Environment, Ethics and Interdependence.” Goleman’s 2014 book, “A Force for Good: The Dalai Lama's Vision for Our World,” combines the Dalai Lama’s key teachings, empirical evidence, and true accounts of people putting his lessons into practice, offering readers guidance for making the world a better place. Having worked with leaders, teachers, and groups around the globe, Daniel Goleman has transformed the way the world educates children, relates to family and friends, and conducts business.
Determinación de la incertidumbre del método de análisis de aflatoxinas por HPLC en pasa de uva
Authors: Martínez Nora Dolores , Rodríguez Ana María , Gutiérrez Aída Rosa , Di Carlo Vitolino Marina Daniela , Durán Analía De los Ángeles
Published: February 2019

Contexto: En este trabajo se presenta la determinación de las incertidumbres de los métodos de análisis de aflatoxinas B1, B2, G1 y G2 en pasa de uva por HPLC-FLD. La incertidumbre de un método es uno de los parámetros requeridos por la norma IRAM 301-ISO/IEC 17025:2005, de aplicación en la República Argentina y acreditada por el Organismo Argentino de Acreditación (OAA). Forma parte de la validación del método analítico. Es un requisito necesario para ampliar el alcance de acreditación del Laboratorio de Análisis de Productos Regionales de Ingeniería Química (LAPRIQ), perteneciente al Instituto de Ingeniería Química de la Universidad Nacional de San Juan.

Metodología: El procedimiento utilizado es el denominado bottom up, basado en una sucesión de etapas de cálculo que tienen en cuenta los errores provenientes de cada una de las operaciones analíticas descompuestas en actividades primarias. La etapa inicial consiste en la identificación de las fuentes de error que pueden afectar el resultado del análisis. Se tomño como base para la determinación de las fuentes de error, y su incidencia en la incertidumbre final del proceso, el procedimiento de espina de pescado de Ishikawa. Definidos los factores que suman al error en la medición, se realizaron todos los ensayos de calibración del HPLC, índice de recuperación y verificación del instrumental para la determinación de la incertidumbre estándar de los subcomponentes. Se calculó luego la incertidumbre combinada teniendo en cuenta los aportes individuales. Posteriormente se sumaron las incertidumbres combinadas, ponderadas según la importancia de su contribución a través del coeficiente de sensibilidad. Por último, se determinó la incertidumbre expandida usando un factor de cobertura K = 2, que implica un porcentaje de confianza del 95 %. Con este factor se puede esperar que se incluya la mayor fracción de la distribución de los valores atribuidos al mesurando.

Resultados: Se detectaron seis fuentes de error, correspondientes a las mediciones de: masa de la muestra, volúmenes de extracción, elución y alícuota para clean up, detección en HPLC e índice de recuperación del método. Las incertidumbres expandidas calculadas de las cuatro aflatoxinas son AFB1= 0,7mg/kg, AFB2= 0,2mg/kg, AFG1 = 0,9 mg/kg y AFG2 = 0,3 mg/kg.

Conclusiones: Los valores de las incertidumbres expandidas se informan en el certificado de análisis, junto con el resultado del ensayo por HPLC, como una de las pruebas de la validación del método.
Simulación numérica CFD de la estructura de control y del sistema de compuertas radiales - represa El Quimbo

Published: February 2019

Contexto: Describir matemáticamente el comportamiento hidráulico en estructuras de control conlleva a ecuaciones diferenciales acopladas no lineales, las cuales no cuentan con solución analítica en la mayoría de los problemas de ingeniería. No obstante, es posible obtener soluciones aproximadas a partir del método de volúmenes finitos (FVM). Este método convierte un medio continuo con variables infinitas en un medio discreto con geometrías establecidas y condiciones de contorno determinadas.

Método: Se desarrolló un modelo numérico en 2D sin considerar el efecto de las pilas y los estribos en el azud, a escala 1:70, bajo condiciones de flujo permanente de la estructura de control y del sistema de compuertas radiales de la represa El Quimbo, a partir de la implementación el software Ansys Fluent 17.0. El análisis hidrodinámico de la estructura se realizó bajo condiciones de superficie libre y con diferentes cargas hidráulicas, para aperturas de 704 msnm, 706,9 msnm, 709,4 msnm, 712 msnm y 724,6 msnm Posteriormente, se validó el modelo numérico a partir de la comparación de los resultados numéricos con los datos teóricos realizados por Ingetec y los datos de las pruebas realizadas en el modelo físico desarrollado por la Universidad Nacional de Colombia (sede Manizales).

Resultados: Para un periodo de retorno de 100 años, el modelo numérico estimó una lámina de 0,0306 m que corresponden a 2,143 m en la estructura El Quimbo. Con esta disposición, ingresó al volumen de control un total de 80,7996 L/s y salieron 80,7324 L/s, originando una variación de caudal de 0,08316 %. La mayor variación de lámina de agua del modelo numérico con respecto a la lámina observada es de 3,1 % (0,258 m), la cual corresponde a la creciente máxima probable para una apertura de compuertas con cota (724,6 msnm) y con una descarga de 290 L/s. De igual forma, las mayores velocidades desarrolladas por el flujo en el vertedero se originan en la salida del deflector, correspondiente a la abscisa K0+ 5,19 m. Según el modelo numérico, se determinó que el impacto del chorro en el canal se hace con una velocidad máxima de 6,15 m/s.

Conclusiones: La relación entre la carga hidráulica con respecto a la carga de diseño no debe superar 1,33, lo cual a su vez concuerda con lo recomendado por la USBR. Asimismo, la condición de cavitación encontrada en la rápida puede ser considerada cavitación incipiente. En el diseño de vertederos, la relación H/HD incide de manera directa en la aparición de fenómenos de cavitación sobre la estructura, en el desarrollo de altas velocidades en la rápida, en el deflector y en la capacidad de descarga del vertedero.

Fenomena plagiarisme dalam dunia akademik bukanlah hal yang baru di Indonesia, perguruan tinggi di Indonesia sudah cukup lama dicemari oleh tindak plagiarisme. Dengan didukungnya kemajuan teknologi yang semakin canggih, salah satunya jaringan internet yang mendunia, memudahkan, cepat, praktis dan murah. Sehingga banyak orang lebih memilih menggunakan internet untuk menyelesaikan  tugasnya seperti membuat karya ilmiah dengan cara copy-paste karya orang lain dari internet tanpa menyebutkan sumber yang digunakan untuk menyelesaikan  tugasnya. Hal tersebut bisa diatasi secara dini menggunakan metode n-gram untuk mengambil potongan karakter huruf  pada dokumen yang akan dicocokan dan Jaccard similarity untuk menghitung berapa persen  kesamaan pada sebuah dokumen yang diproses menggunakan algoritma winnowing. Algoritma winnowing merupakan algoritma yang digunakan untuk mencocokan karakter huruf atau angka pada dua dokumen dengan teknik hashing. Kata kunci: N-gram, Jaccard Similarity, Algoritma Winnowing.
