The Truth About Honesty
Authors: Wells Dominic D. , Molina Anthony D.
Published: December 2017

This article examines the ethics of honesty and deception in public administration. Building on previous research showing that public administrators rank honesty as an essential public service value but also sometimes use deception while carrying out their duties, semi-structured interviews with public employees were conducted to explore this apparent tension. Specifically, this study asks: Why is honesty important for public administrators? What is honesty and dishonesty? Under what circumstances is the use of deception by public administrators legitimate? The American Society for Public Administration (ASPA) Code of Ethics is used as an analytical framework to assess the cases and examples provided by participants. The article concludes with a discussion of some important implications that this research has for public administration practice, teaching, and research.

O impacte do sistema de Gestão do Desempenho nas relações laborais no contexto da Administração Pública | Perspetivas encontradas na literatura
Authors: Marques Andreia Fernandes , Rodrigues Ana Cláudia
Published: December 2017

No âmbito da modernização da Administração Pública portuguesa foi estabelecido o Sistema Integrado de Gestão e Avaliação do Desempenho na Administração Pública, (SIADAP), que “visa contribuir para a melhoria do desempenho e qualidade de serviço da administração pública, para a coerência e harmonia da ação dos serviços, dirigentes e demais trabalhadores e para a promoção da sua motivação profissional e desenvolvimento de competências” (artigo 1.º, Lei n.º 66-B/2012, de 31 de dezembro).A investigação científica tem estudado vários aspetos dos sistemas de gestão e avaliação de desempenho, no entanto, há uma temática ainda pouco explorada: a das consequências reais destes sistemas. O presente trabalho visa atualizar a tipologia idealizada por Franco-Santos, Lucianetti e Bourne (2012), com as novas perspetivas da literatura, procurando caracterizar as consequências da implementação dos sistemas de avaliação de desempenho ao contexto da Administração Pública.
VASCULAR PATHOLOGY OF AN EYE AND THE THREAT OF DEVELOPING AGE-RELATED MACULAR DEGENERATION AFTER RADIATION EXPOSURE
Authors: Fedirko Pavlo , Sakovich Vasiliy , Garkava Natalia
Published: December 2017

On the contrary to the previous expectations, the most common Chornobyl catastrophe victim’s pathology was the vascular pathology of an eye. The work is devoted to the assessment of changes in capillary tubes, arterioles and venules, which were irradiated as a result of Chornobyl catastrophe and those who have been exposed to radiation while working in the Chornobyl exclusion zone.

The results of eye vascular system examination is presented by 615 persons: 358 Chornobyl clean-up workers, inspected in 1993–1994, 2007–2008 and 257 participants of works at the «Shelter» object, that were inspected in 2007–2008 and in 2017.

Microcirculatory damages in conjunctiva are the most early ionizing radiation induced eye damage. Dose dependence from microcirculatory damages in conjunctiva has been proved. The conjunctiva index, which characterizes the evaluation degree of microcirculatory abnormalities value for individuals irradiated at a dose of up to 10 mSv was 5.33±0.34, at a dose of 10 to 30 mSv – 9.71±0.93. Thus, a significant (t=4.42, p<0.05) increase in the display of microcirculatory abnormalities in conjunctiva was revealed with an increase in the dose load. In the correlation analysis, there was found a direct connection, r = 0.48, between the conjunctiva index and the dose of irradiation.

The expressive tendency to correlate the negative dynamics of the macular zone with the degree of deterioration of microcirculation shows the effect of microcirculatory disorders on the development of age-related macular degeneration. At the correlation analysis, there was found a direct connection of significant decreased number of functioning capillaries with the deterioration of the macular zone of the retina (r=0.37). It is also advisable to appoint prophylactic complexes of lutein and zeoxanthine to patients in the case of microcirculatory disorders.

Authors: Nyzhnyk Taras
Published: December 2017

Titanium compounds are very perspective reagents for water treatment because of their many outbreaking benefits compared to traditional coagulants – smaller dosage, lesser pH-dependency, they are biologically inert, work at low water temperature. But they have some technological issues, preventing them from wide use. One of the ways to overcome this issues shown in this article. Results of use of nanoencapsulation of Ti(IV) salts into solvable cells shown. This way allows to overcome problem with too quick hydrolysis and evenly distribution of coagulant in treated water. Also titanium coagulant was practically compared to traditional coagulant to show benefits of titanium-based coagulants
Do coherent risk measures identify assets risk profiles similarly? Evidence from international futures markets
Authors: Mozumder Sharif , Humayun Kabir M. , Dempsey Michael
Published: December 2017

The authors consider Lévy processes with conditional distributions belonging to a generalized hyperbolic family and compare and contrast full density-based Lévy-expected shortfall (ES) risk measures and Lévy-spectral risk measures (SRM) with those of a traditional tail-based unconditional extreme value (EV) approach. Using the futures data of leading markets the authors find that ES and SRM often differ in recognizing the risk profiles of different assets. While EV (extreme value) is often found to be more consistent than Lévy models, Lévy measures often perform better than EV measures when compared with empirical values. This becomes increasingly apparent as investors become more risk averse.
Discriminación, pobreza y vulnerabilidad: los entresijos de la desigualdad social en México
Authors: Ordóñez Barba Gerardo
Published: December 2017

En este artículo se presenta un acercamiento al estudio de la relación entre la discriminación y la pobreza en México. Con las bases de datos de la Encuesta nacional sobre discriminación de 2010, se cuantifica la importancia de la pobreza sobre las actitudes y comportamientos discriminatorios que sufre la población en general, y también los grupos de mujeres, adultos mayores, jóvenes, personas con discapacidad, minorías religiosas, minorías étnicas, minorías sexuales y personal doméstico, considerados por el Consejo Nacional para Prevenir la Discriminación, como poblaciones en situación de discriminación. Para ello se construyó un indicador de pobreza y un índice que mide su importancia relativa como factor de discriminación, en el ámbito de las percepciones y en lo referente a las experiencias de los individuos como víctimas. La evidencia muestra que la discriminación tiene mayor incidencia entre las personas en condición de pobreza, y que se repite para la mayoría de los grupos vulnerables.
Nutritional Assessment of Under Five Children Attending Pediatric Clinic in a Tertiary Care Hospital in the Capital of Nepal
Authors: Chhetri Uma Devi , Sayami Sujan , Mainali Prabha
Published: December 2017

Introduction: There has been a decreasing trend in malnutrition (stunting, wasting, and under-weight) in Nepal from 2001 till 2016 according to Nepal demographic health survey 2016. We tried to study whether these national survey data equally reflect the nutritional status of children visiting hospitals in the capital city of our country. The objective of the study was to evaluate the nutritional status of children less than five years of age brought to a hospital in Kathmandu.
Methods: Anthropometric measurements (height/length and weight), other demographic details, and morbidity of all children, six months to five years of age, visiting the hospital over the period of three months were collected from the out-patient register. Height-for-age, weight-for-height, and weight-for-age were calculated and expressed as standard deviation units as compared to the median of reference data taken from WHO Multicentre Growth Reference Study Group (2007). Association between morbidity and various anthropometric values were calculated.
Results: A total of 424 children were included in the study. There were 2.1% severely stunted, 8% stunted, 2.8% tall, and 1.7% very tall children. Similarly, 6.4% were severely wasted, 14.4% wasted, 4.7% severely under-weight, and 12.3% under-weight. The anthropometric values were significantly associated with morbidity (acute Vs chronic) but not associated with whether they were from within Kathmandu or form outside, and individual morbidity.
Conclusion: Wasting and severe wasting in under five children from and nearby Kathmandu of Nepal is higher while stunting and severe stunting is lower as compared to previous National reports.
El comercio intra-industrial mexicano con algunas economías latinoamericanas representativas (2000-2016)
Authors: Jaime Camacho Daniel David
Published: December 2017

La economía mexicana es considerada una de las economías exportadoras de manufacturas más exitosas en el mundo, sin embargo, a pesar de la cantidad de tratados y acuerdos que existen con los países de la región, su desempeño comercial con Centroamérica y Sudamérica ha sido tradicionalmente pobre. El trabajo examina de manera empírica el comportamiento del comercio intra-industrial (CII) mexicano con las economías más representativas de la región latinoamericana a través de la estimación del índice Grubel-Lloyd (IGL). Este índice, sin ser catalogado como una medida perfecta, ha sido valorado como un buen indicador de la integración de la industria manufacturera en las economías desarrolladas. Las estimaciones realizadas con base en la Clasificación Uniforme de Comercio Internacional (CUCI) para este grupo de países concluyen que existe evidencia favorable para presumir que el comercio intra-industrial de México con los países de la región se ve influenciado por el nivel de desarrollo económico e industrial de los países participantes más que por cuestiones de acercamiento regional

Análisis del ajuste del área inundable obtenida mediante una evaluación integrada de la peligrosidad de inundación y peligros asociados
Authors: Perles Roselló María Jesús , Gallegos Reina Antonio , Cantarero Prados Francisco
Published: December 2017

En el texto se analiza el ajuste de distintas estrategias metodológicas para la evaluación del área inundable. Para ello se compara la extensión de la lámina de inundación en un evento real concreto, con la predicción de la misma obtenida a partir de dos modelos de simulación de la inundación. En un caso, la predicción se realiza mediante el programa HEC-RAS, y en el segundo caso este modelo se ve modificado a través de la evaluación integrada de la inundación y otros peligros que inciden directamente en la expansión de la lámina de agua (erosión hídrica y movimientos gravitacionales). Se ha utilizado como caso de análisis la inundación producida en las cuencas de los arroyos Gallegos y Las Piletas (costa oriental de la provincia de Málaga) en los días 27 y28 de marzo de 2004, a partir de un evento pluviométrico de 229 mm en 24 h. Los resultados muestran un desfase considerable entre la realidad y las predicciones según ambos modelos, aunque se observa que la evaluación integrada de peligros asociados proporciona un mejor ajuste del área inundable.

Authors: Castro Higueras Antonio , Monedero Morales Carmen del Rocío , Luengo Benedicto Juan Tomás
Published: December 2017

El uso de las Tecnologías de la Información y la Comunicación (TIC) como herramientas de enseñanza se ha consolidado como una alternativa dentro y fuera del aula que permite el desarrollo de procesos de aprendizaje significativo y colaborativo y en los que se da una mayor interacción entre el estudiante y el objeto de estudio. A partir de esta premisa, un grupo de profesores de la Facultad de Ciencias de la Comunicación de la Universidad de Málaga han puesto en marcha un proyecto de innovación educativa consistente en la realización de vídeotutoriales sobre los distintos equipos presentes en los laboratorios audiovisuales, así como de ciertas habilidades comunicativas generales útiles para la superación de asignaturas enmarcadas en los grados en Periodismo, en Publicidad y Relaciones Públicas y en Comunicación Audiovisual. Tras la realización, bajo la supervisión del tutor de la materia, de los vídeotutoriales por parte de los alumnos se les asociaron códigos QR ubicados en los equipos y en las aulas. Este artículo analiza el proceso de desarrollo de la primera fase del proyecto, así como los resultados de dos cuestionarios de detección de necesidades de aprendizaje enviados a los alumnos y al profesorado de la Facultad, en los que se revelan tanto la demanda de implementación de este tipo de metodologías por parte del alumnado, como la actitud positiva hacia su uso por parte de los docentes.

Published: December 2017

Podocin protein is encoded by the NPHS2 gene is largely responsible for resistance to corticosteroid in pharmacological treatment of nephrotic syndrome. Therefore, we have constructed the genotyping test of NPHS2 polymorphisms on 149 pediatric patients with primary nephrotic syndrome. Main methods consisted of DNA extraction from peripheral blood samples, polymerase chain reaction (PCR) and Sanger sequencing. In my study, 251 SNPs from 6 exons and 2 new mutations have detected by genotyping test. These results will provide helpful tool and data for further research to determine the role of NPHS2 polymorphisms with corticosteroid response in the treatment of nephrotic syndrome.
A instantes
Authors: Cardona Álvaro Andrés
Published: December 2017

A instantes (2017) materializa el afán de ver la si­tuación de los presos políticos –hombres y muje­res- en las cárceles de Colombia después de la fir­ma del Acuerdo de Paz. El proceso de creación de la obra entreteje dos lenguajes: el audiovisual y el fotográfico. La metodología gira entorno a una fo­tografía instantánea que toma una compañera de la cárcel y, enseguida de su toma, la foto se ubica en la mano del retratado para dejar que la cámara au­diovisual documente desde lo invisible la figura de esa persona que está “a instantes” de recuperar la libertad. A partir del performance alrededor de la foto instantánea se genera un trabajo paralelo que nace desde los símbolos, elementos del entorno que insinúan anhelos, que muestran las precariedades del sistema carcelario y que se combinan en el cuer­po y el espacio lo que hay más allá de las paredes. Este trabajo se realizó con el apoyo de la coalición de organizaciones “Larga vida a las mariposas” y el realizador audiovisual Luis David Acosta.

Published: December 2017

Acorde a la hipótesis de Warburg, las células cancerígenas, seleccionan la glucólisis aerobia, como la principal forma de metabolizar la glucosa en lugar de la fosforilación oxidativa, debido a ello las células tumorales captan más moléculas de glucosa, para generar acido láctico, necesario para mantener el micro ambiente celular.

Hoy en día, los procesos de reprogramación metabólica, han llevado al estudio de diversos oncogenes y genes supresores, que se encargan en las células proliferantes de la reprogramación del metabolismo mitocondrial.

Así, la acidosis láctica tipo B, los fenómenos metabólicos de reprogramación, la sobre expresión de hexoquinasa II y alteraciones en la pirofosfato de tiamina, (PPT) entre otras, causan elevaciones del lactato, que han sido pobremente descritas.

Con lo antes mencionado, intentamos adentrarlos, en esta revisión, al conocimiento del lactato y el cáncer.
Omega-3 in the Prevention of Cardiovascular Diseases
Authors: Cerón Sandoval Martha Izbeth , Sandoval Gallegos Eli Mireya
Published: December 2017

In the last years, Mexico has experimented changes in the epidemiological and nutritional transition. There is a decrease of communicable diseases and an increase of chronic diseases, becoming the main causes of death, mainly cardiovascular diseases. Experimental, epidemiological and interventional studies have demonstrated the beneficial cardiovascular effects of eicosapentaenoic acid (EPA) and docosahexanoic acid (DHA), which have antiatherosclerotic, antithrombotic, antiarrhythmic and anti-inflammatory effects. The American Dietetic Association recommend an ingestion of 250 to 1000 mg/day of omega 3. This paper mentions the functional characteristics, biosynthesis and mechanisms of omega-3 fatty acids. This paper also reviews the clinical evidence that support their role as a cardioprotective factor. Derived from the analysis of the reviewed studies, it is concluded that taking into account the benefits of omega-3 fatty acids in the prevention and treatment of cardiovascular diseases, it is necessary to increase the consumption of foods rich in these fatty acids.

Bu çalışmada kontrollü koşullarda büyütülen I. tinctoria (çivitotu) bitkisinin çevresel stres koşullarına
toleransı ve dışsal poliaminlere tepkisi araştırılmıştır. İlk aşamada
bitkiler dört farklı tuz derişimindeki (0, 50, 100 ve 200 mM) NaCl solüsyonu
ile sulanarak tuz stresine maruz bırakılmıştır. Bitkiler genelde artan tuz
dozlarını tolere ederken, 200 mM’lık
tuz konsantrasyonundan etkilenmiş ve indigo da dahil olmak üzere verim
düşmüştür. İkinci aşama olarak fideler kuraklık stresine maruz
bırakılmış ve 3., 7. ve 10. günde kuraklığın etkileri incelenmiştir. Kuraklıkta
geçen gün sayısı arttıkça indigo ve
verimde azalma olmuş, en düşük değerler 10. gündeki verilerden elde edilmiştir.
Üçüncü aşama olan poliamin uygulamasında spermin, spermidin ve putresin
poliaminleri dört farklı konsantrasyonda (0, 0.1, 1 ve 2 mM) yapraktan
uygulanmıştır. Uygulamada tüm
poliaminler indigo ve fide verimini arttırmış, en iyi sonuç putresinden elde

Authors: Dhital Saroj Prasad , Koirala Udaya , Karki Kushal , Joshi Bijendra Dhoj , Upadhyaya Amit Mani
Published: December 2017

Background: Emergency appendectomy is the commonest emergency surgical procedure being performed for many years. Till now, the dictum is that it should be done as soon as possible from the onset of attack.Objectives: To evaluate immediate surgical outcome in cases undergone appendectomy after hospital delay of more than 12 hours duration compared with appendectomy done immediately within 12 hours of presentation.Methods: This is a retrospective study of 118 patients on whom appendectomies were done between 1st June 2008 to 31st August 2010. These patients were divided into two groups on the basis whether the appendectomy was done ≤ 12hours or >12 hours from the time of presentation in the hospital and intergroup comparison was made regarding length of hospital stay, rate of perforation and post operative complications.Results: A total of 118 patients were included in the study. Out of which 71(60.2%) were male and 47(39.8%) were female. Mean age of patients was 30.97 ± 12 years. Mean duration of hospital stay was 4.35 ± 1.75 days. In comparison of two groups of ≤ 12 hours or >12 hours from the time of presentation in the hospital, there were no statistically significant difference in length of hospital stay (4.29 vs 4.4 days, p=0.7), rate of perforation of appendix (9.25% vs 10.93%, p=0.3) and post-operative wound infection (16.66% vs 17.18%, p = 0.9).Conclusion: Delaying an appendectomy for a valid reason can be considered. Prospective trials are required to establish findings of this study.Journal of Kathmandu Medical College, Vol. 5, No. 4, Issue 18, Oct.-Dec., 2016, Page: 112-115

OBJECTIVE

Multiple sclerosis (MS) is a chronic autoimmune disease that causes demyelination and axonal loss. Walking difficulties are a common and debilitating symptom of MS; they are usually caused by spastic paresis of the lower extremities. Although intrathecal baclofen (ITB) therapy has been reported to be an effective treatment for spasticity in MS, there is limited published evidence regarding its effects on ambulation. The goal of this study was to characterize ITB therapy outcomes in ambulatory patients with MS.

METHODS

Data from 47 ambulatory patients with MS who received ITB therapy were analyzed retrospectively. Outcome measures included Modified Ashworth Scale, Spasm Frequency Scale, Numeric Pain Rating Scale, and the Timed 25-Foot Walk. Repeated-measures ANOVA was used to test for changes in outcome measures between baseline and posttreatment (6 months and 1 year). Significance was set at p < 0.05. Descriptive data are expressed as the mean ± SD, and results of the repeated-measures ANOVA tests and the Wilcoxon rank-sum test are expressed as the mean ± SEM.

RESULTS

There was a statistically significant reduction in the following variables: 1) aggregate lower-extremity Modified Ashworth Scale scores (from 14.8 ± 1.0 before ITB therapy to 5.8 ± 0.8 at 6 months posttreatment and 6.4 ± 0.9 at 1 year [p < 0.05]); 2) Numeric Pain Rating Scale scores (4.4 ± 0.5 before ITB, 2.8 ± 0.5 at 6 months, and 2.4 ± 0.4 at 1 year [p < 0.05]); 3) spasm frequency (45.7% of the patients reported a spasm frequency of ≥ 1 event per hour before ITB therapy, whereas 15.6% and 4.3% of the patients reported the same at 6 months and 1 year posttreatment, respectively [p < 0.05]); and 4) the number of oral medications taken for spasticity (p < 0.05). Of the 47 patients, 34 remained ambulatory at 6 months, and 32 at 1 year posttreatment. There was no statistically significant change in performance on the Timed 25-Foot Walk test over time for those patients who remained ambulatory.

CONCLUSIONS

In this retrospective study, the authors found that ITB therapy is effective in reducing spasticity and related symptoms in ambulatory patients with MS. Because the use of ITB therapy is increasing in ambulatory patients with MS, randomized, prospective studies are important to help provide a more useful characterization of the effects of ITB therapy on ambulation.
Reduction of hyperthermia in pediatric patients with severe traumatic brain injury: a quality improvement initiative

Published: December 2017

OBJECTIVE

Severe traumatic brain injury remains a leading cause of morbidity and mortality in the pediatric population. Providers focus on reducing secondary brain injury by avoiding hypoxemia, avoiding hypotension, providing normoventilation, treating intracranial hypertension, and reducing cerebral metabolic demand. Hyperthermia is frequently present in patients with severe traumatic brain injury, contributes to cerebral metabolic demand, and is associated with prolonged hospital admission as well as impaired neurological outcome. The objective of this quality improvement initiative was to reduce the duration of hyperthermia for pediatric patients with severe traumatic brain injury during the initial 72 hours of admission to the pediatric intensive care unit.

METHODS

A retrospective chart review was performed to evaluate the incidence and duration of hyperthermia within a preintervention cohort. The retrospective phase was followed by three 6-month intervention periods (intervention Phase 1, the maintenance phase, and intervention Phase 2). Intervention Phase 1 entailed placement of a cooling blanket on the bed prior to patient arrival and turning it on once the patient’s temperature rose above normothermia. The maintenance phase focused on sustaining the results of Phase 1. Intervention Phase 2 focused on total prevention of hyperthermia by initiating cooling blanket use immediately upon patient arrival to the intensive care unit.

RESULTS

The median hyperthermia duration in the preintervention cohort (n = 47) was 135 minutes. This was reduced in the Phase 1 cohort (n = 9) to 45 minutes, increased in the maintenance phase cohort (n = 6) to 88.5 minutes, and decreased again in the Phase 2 cohort (n = 9) to a median value of 0 minutes. Eight percent of patients in the intervention cohorts required additional sedation to tolerate the cooling blanket. Eight percent of patients in the intervention cohorts became briefly hypothermic while on the cooling blanket. No patient required neuromuscular blockade to tolerate the cooling blanket, experienced an arrhythmia, had new coagulopathy, or developed a pressure ulcer.

CONCLUSIONS

The placement of a cooling blanket on the bed prior to patient arrival and actively targeting normothermia successfully reduced the incidence and duration of hyperthermia with minimal adverse events.
Design and Testing of a 2D Optical Fiber Sensor for Building Tilt Monitoring Based on Fiber Bragg Gratings
Authors: Chao Chung-Ru , Liang Wei-Lun , Liang Tsair-Chun
Published: December 2017

In this paper, a new type of optical fiber tilt sensor based on fiber Bragg grating (FBG) is presented for 2D dual-axis tilt angle sensing. The tilt sensor is composed of two cylindrical floats suspended in water, connected with FBG. When the external environment causes the tilting of the sensor, the surface of the liquid within the container will form a new balanced liquid surface plane due to the gravity and change the height of the liquid at different locations in the container. So the buoyancy force of the cylindrical floats of the sensor will vary with the depth of liquid, thus the changed FBG strain will cause the FBG reflection central wavelength shift. According to the measured central wavelength shift by the optical spectral analyzer (OSA), we can obtain the two-axis tilt angle of the sensor. The proposed sensor can detect a tilt angle range of −5 degrees to +5 degrees and achieve a sensitivity of 0.1° with optical spectrum analyzer resolution of 0.01 nm. Due to its good sensing linearity, the proposed sensor can be applied in building tilt measurement.

Classification of a series of Australian beers was performed using synchronous scanning fluorescence spectroscopy and emission-excitation matrices based on the IR fingerprint regions. The results indicate that synchronous scanning fluorescence spectroscopy is a robust and valuable method to discriminate between Australian lager beers based on their brand name. In addition, a subsequent spoiling study revealed that when beers are opened and stored at 4 °C for 4 weeks, the results demonstrated that the beers were not statistically different. The methods and techniques outlined may be of interest to brewing companies and microbrewers to determine the unique beer spectrum.
An Improved Approach to Estimate Three-Phase Relative Permeability Functions for Heavy-Oil Displacement Involving Instability and Compositional Effects

Published: December 2017

Simultaneous three-phase flow of gas, oil and water is a common phenomenon in enhanced oil recovery techniques such as water-alternating-gas (WAG) injection. Reliable reservoir simulations are required to predict the performance of these injections before field application. However, heavy oil displacement by gas or water can lead to viscous fingering due to the unfavorable mobility ratio between heavy oil and the displacing fluid. In addition, the injection of partially dissolvable gases such as CO2 can result in compositional effects, which can bring about a significant reduction of oil viscosity and hence can cause variations of the mobility ratio. Estimations of three-phase relative permeability under such conditions are extremely complex, and using conventional techniques for the estimation can lead to erroneous results. We used the results of four coreflood experiments, carried out on a core, to estimate two-phase and three-phase relative permeability. A new history matching methodology for laboratory experiments was used that takes into account the instability and the compositional effects in the estimation processes. The results demonstrate that a simultaneous CO2 and water injection (CO2-simultaneous water and gas (SWAG)) can be adequately matched using the relative permeabilities of a secondary gas/liquid and a tertiary oil/water. In heavy oil WAG injection, the injected water follows the CO2 path due its lower resistance as a result of the CO2 dissolution in the oil and the resultant reduction of the oil viscosity. This is contrary to WAG injection in conventional oils, where gas and water open up separate saturations paths. It is also important to include capillary pressure (Pc), even in high permeable porous media, as we observed that the inclusion of capillary pressure dampened the propagation of the viscous fingers and hence helped the front to become stabilized, leading to a more realistic simulated sweep efficiency.
Optimizing the Structure of the Straight Cone Nozzle and the Parameters of Borehole Hydraulic Mining for Huadian Oil Shale Based on Experimental Research
Authors: Wen Jiwei , Chen Chen
Published: December 2017

Oil shale is a kind of potential alternative energy source for petroleum and has attracted the attention of energy researchers all over the world. Borehole hydraulic mining has more prominent advantages than both conventional open-pit mining and underground mining. It is very important to attempt to use the borehole hydraulic mining method to exploit underground oil shale. The nozzle is the key component of borehole hydraulic mining and reasonable mining parameters are also crucial in exploiting underground oil shale efficiently. The straight cone nozzle and the oil shale of Huadian area will be taken as the research objects. The self-developed, multifunctional, experimental device can test both the jet’s performance as well as the breaking of oil shale by the high-pressure water jet using the straight cone nozzle and varying structural parameters. Comprehensive analysis of the results of an orthogonal experimental design, including range analysis and variance analysis, demonstrate the optimal structural parameters of a straight cone nozzle as follows: the outlet diameter is 4 mm, the length to diameter ratio is 2.5, and the contraction angle is 60°. In addition, in order to maximize the efficiency of borehole hydraulic mining for Huadian oil shale, the non-submerged jet should be placed parallel to the oil shale bedding. These results can provide scientific and valuable references for borehole hydraulic mining of oil shale.

Ashes derived from the combustion of vegetal and animal biomass still represent a mostly unexplored secondary raw material for the production of alkali-activated materials, given their peculiar chemical nature. In this work, calcium phosphate biomass ashes were successfully used as partially reactive fillers in a metakaolin-based geopolymer composite to produce, by direct foaming, sustainable and lightweight boards with thermal insulating properties. The investigated materials were obtained by activating a blend of metakaolin and biomass ash in a weight ratio of 1: 1 and foamed with the addition of H2O2 in measure of 5 wt. %, to maximize the volume of disposed ash and ensure adequate properties to the material at the same time. The obtained geopolymer composite was characterized by microstructural, chemical-physical, mechanical and thermal analysis: the obtained results showed that biomass ash and metakaolin well integrated in the microstructure of the final porous material, which was characterized by a density of about 310 kg/m3 and a thermal conductivity of 0.073 W/mK at a mean test temperature of 30 °C, coupled with an acceptable compressive strength of about 0.6 MPa. Dilatometric and thermogravimetric analysis, performed up to 1000 °C, highlighted the thermal stability of the composite, which could be regarded as a promising material for low-cost, self-bearing thermal insulating partitions or lightweight cores for thermostructural sandwich panels.
