Cost and Time Effective Stimulation Technique in Horizontal Cemented Liner Application in Carbonate Reservoir With HPCT Hydrajetting Tools
Authors: Alfayiz Mohammad , Alaithan Monaf , Alharbi Abdulaziz , Khan Faisal
Published: March 2019

Tight carbonate gas reservoirs require stimulation in order to establish commercial viability. In order for the development plan to be considered effective and successful, two main parameters have to be studied and evaluated, time, and cost. The conventional method to stimulate tight carbonate reservoirs is bull heading acid fracturing treatment, which is costly and time consuming for multi stages wells, not excluding the high treatment pressure requirement and risk associated with it. Conventional plug and perf technique includes e-line operations to perforate with guns, acid fracturing treatment by bullheading, and e-line operations to set plugs for every single stage.

A novel acid-soluble abrasive material, was implanted and tested as an economical and time effective alternative solution. The technique involves perforating through cemented liners utilizing the abrasive material flowed by low volume acid surgesqueeze. By using this technique time and cost associated with the conventional plug and perf technique, can be reduced and achieve even better result with less cost and time.

The wells that were stimulated with this technique, were tested and proven superior in terms of production rate over the conventional plug and perf technique in the short term. More evaluation to be done on the wells over the long term and evaluate if they are going to sustain the production over time.

This paper provides a brief summary about the technique. Also, will discuss in details, the cost and time effectiveness, the short term result, and compare it with the conventional plug and perf technique.
Effects of Pre-Existing Fractures on Carbonate Matrix Stimulation Studied by Large-Scale Radial Acidizing Experiments

Carbonate reservoirs host a significant amount of hydrocarbon reserves in the Middle East and worldwide. In matrix acidizing stimulation, hydrochloric acid (HCl) is commonly injected into the well at pressures less than fracturing pressure to dissolve the carbonate rock and create high-conductivity channels, known as wormholes. Wormholes propagate through the damaged near-wellbore zone connecting the well with the reservoir. In this work, we aim to study the effects of pre-existing fractures on wormhole development.

Matrix acidizing processes were reproduced in controlled laboratory experiments where a 15% HCl solution was injected into a borehole drilled in a carbonate block sample containing pre-existing fractures, allowing the acid to penetrate radially into the rock sample. The experiment was conducted inside a polyaxial load frame to accommodate large block samples (20×16×16 in.). Prior to acid injection, the block was fully saturated with water and taken to 2,000-psi pore pressure and 4,000-psi confining stress to simulate downhole conditions. To evaluate the created wormholes, the tested block was cut open along the fractures followed by X-ray CT scanning of selected zones.

Here we report experimental results for matrix stimulation of one Indiana limestone block containing a series of parallel pre-existing fractures. Acid was injected at a constant rate through the 1-in. diameter borehole containing an 8-in.-long openhole section in the center of the block. Although the acid injection pressure was maintained below the pressure required to open the fractures, acid breakthrough was found to be governed by the pre-existing fractures. Indeed, unlike similar radial acidizing experiments in intact blocks, there were no indications of wormholes exiting the outer faces of the block. Moreover, the post-test evaluation of the central fracture along the openhole section clearly revealed the wormholes that etched the fracture faces. However, a closer look into the stimulated openhole section showed that the wormholes initiated in other directions inside the matrix as well. An X-ray CT scan of a 4-in. diameter cored borehole regions allowed us to compare the density and characteristics of the wormhole growth along the fracture and into the matrix.

Although radial acidizing experiments describe more closely real conditions of matrix acidizing, few cases have been published, particularly for large-block experiments. The large-scale block experiments presented in this study provide new insights on the impact of pre-existing fractures on wormholing mechanisms.
Tiempo e interpretación en la teoría de la relatividad
Authors: Simesen de Bielke Martín
Published: March 2019

En la teoría de la relatividad se presenta el problema de la realidad o irrealidad de los fenómenos relativistas relacionados con el espacio-tiempo (dilatación de la duración, contracción de la longitud, quiebre de la simultaneidad provocada por el movimiento de escalas y relojes). En la primera parte de este artículo se esboza el marco de la discusión en relación con este punto de controversia. Luego de que el marco ha quedado establecido, se toman en consideración algunos experimentos mentales de Einstein para demostrar por qué el tiempo relativista no puede ser caracterizado ni como algo real ni como mera apariencia. A lo largo del análisis crítico, la función de la expresión «como si» juega un rol importante en la comprensión de por qué el tiempo es interpretación, antes que una «cosa» real o una «ilusión».

Published: March 2019

Background:

In this study, the essential oil composition and cytotoxic activities of five Artemisia species were determined.

Methods:

The collected plants were water-distilled separately to obtain oils which were then subjected to gas chromatography (GC) and gas chromatography/mass spectrometry GC/MS analyses to identify their compositions. Cancer cells were exposed to different concentrations of samples and cell viability was measured using AlamarBlue® assay. Apoptotic cells were analyzed by propidium iodide (PI) staining and flow cytometry.

Results & Conclusion:

To study the amount of pro-apoptotic proteins and the apoptosis mechanism, Western blot method was used. Although all samples were cytotoxic at the highest concentration, the oil of A. kulbadica showed the strongest activity among other plants. Carvacrol (IC50 21.11 μg/ml) had the most cytotoxic effects among other components. Carvacrol, 1,8-cineole and 4-terpineole caused an increase in the amount of Bax protein and cleaved peroxisome proliferator-activated receptors (PPAR) and caspase proteins in DU 145 cells.
The Role of Vitamin D and Sunlight Incidence in Cancer
Authors: Camara Alice B. , Brandao Igor A.
Published: March 2019

Background:

Vitamin D (VD) deficiency affects individuals of different ages in many countries. VD deficiency may be related to several diseases, including cancer.

Objective:

This study aimed to review the relationship between VD deficiency and cancer.

Methods:

We describe the proteins involved in cancer pathogenesis and how those proteins can be influenced by VD deficiency. We also investigated a relationship between cancer death rate and solar radiation.

Results:

We found an increased bladder cancer, breast cancer, colon-rectum cancer, lung cancer, oesophagus cancer, oral cancer, ovary cancer, pancreas cancer, skin cancer and stomach cancer death rate in countries with low sunlight. It was also observed that amyloid precursor protein, ryanodine receptor, mammalian target of rapamycin complex 1, and receptor for advanced glycation end products are associated with a worse prognosis in cancer. While the Klotho protein and VD receptor are associated with a better prognosis in the disease. Nfr2 is associated with both worse and better prognosis in cancer.

Conclusion:

The literature suggests that VD deficiency might be involved in cancer progression. According to sunlight data, we can conclude that countries with low average sunlight have high cancers death rate. New studies involving transcriptional and genomic data in combination with VD measurement in long-term experiments are required to establish new relationships between VD and cancer.

Authors: Muhammad Zeinab A. , Alshehrei Fatimah , Zayed Mohie E.M. , Farghaly Thoraya A. , Abdallah Magda A.
Published: March 2019

Background:

bis-heterocycles especially those containing pyrazole moiety display much
better antibacterial activity than mono heterocycles.

Objective:

Herein, we synthesised a series of new bis-pyrazoles and investigated their antimicrobial
agents.

Methods:

A novel series of bis-pyrazole derivatives have been synthesized in good yield by coupling
reaction of cyanoacetic acid 4-[(2-cyano-acetyl)-hydrazonomethyl]-benzylidene-hydrazide with a
number of diazonium salts of aromatic amines in DMF in the presence of NaOH. Refluxing of the produced
hydrazones with hydrazine-hydrate in ethanolic solution afforded the respective bis-pyrazoles.
On the other hand, the reaction of bis(cyanoacetic acid hydrazide) derivative with a diversity of hydrazonoyl
chlorides in dioxane under reflux gave bis-pyrazoles.

Results:

The structures of all the products were discussed and assured from all possible spectral data as
well as for the elemental analysis. In addition, the results of the antimicrobial activity examination of
selected derivatives revealed a high strength of some tested compounds compared to standard bactericides
and fungicides utilized. Molecular docking of the newly synthesized compounds into the Enoyl
ACP reductase active site supported the in vitro antimicrobial activity. All the tested compounds could
fit in the enzyme binding pocket with significant binding affinities (-7.040 to -9.141 Kcal/mol).

Conclusion:

The good results of the antimicrobial examination of the newly synthesized bis-pyrazoles
comprise the considerable evidence of the importance of bis-heterocyclic compounds which encourages
us to continue designing and synthesising a novel series with potent biological activity in the future.
A Comprehensive Review on the Screening Models for the Pharmacological Assessment of Antiulcer Drugs
Authors: Mishra Abhinav P. , Bajpai Ankit , Chandra Suresh
Published: March 2019

Background:

Due to inappropriate diet, smoking, alcohol consumption, regular use of drugs like NSAIDs and sedentary lifestyle, one may feel upper abdominal pain which may be the predictor of the gastrointestinal disorder called Peptic Ulcer. When an imbalance occurs between the defensive factor and aggressive factor of the stomach, ulcer formation in the esophageal lining, stomach, or duodenum takes place. This leads to the formation of small sores that cause pain. Another condition that synergizes the abdominal pain is vomiting materials which look like coffee grounds, blood in the stool, black or tarry stools. This pain may increase after lunch or dinner. This problem persists, that often leads to the gastroenterologist's consultation.

Objective:

There are many antiulcer screening models present for the determination of antiulcer activity of the drug molecule. The main objective of this study is to find which model is best for the determination of antiulcer activity.

Methods:

A literature search was conducted on the databases namely Science direct and PubMed with the help of different keywords such as "Anti-ulcer", "In-vitro models" and "In-vivo models". The search was customized by applying the appropriate filters so as to get the most relevant articles to meet the objective of this review article.

Result:

There are different research and review papers based on the antiulcer screening models for the determination of antiulcer activity of new drug molecules.

Conclusion:

On the basis of our study, we found some useful models for the antiulcer activity of drugs and suggested that, if we use in-vitro and in-vivo methods together, then we may obtain the most relevant result in our research area.

Authors: Demir Meral , Akarsu Emel O. , Dede Hava O. , Bebek Nerses , Yıldız Sevda O. , Baykan Betül , Akkan Ahmet G.
Published: March 2019

Objective:

We aimed to determine the therapeutic drug monitoring (TDM) features and
the relation to Brain-Derived Neurotrophic Factor (BDNF) of frequently used new antiepileptic
drugs (NADs) including lamotrigine (LTG), oxcarbazepine (OXC), zonisamide (ZNS) and lacosamide
(LCM). Moreover, we investigated their effect on the quality of life (QoL).

Methods:

Eighty epileptic patients who had been using the NADs, and thirteen healthy participants
were included in this cross-sectional study. The participants were randomized into groups. The
QOLIE-31 test was used for the assessment of QoL. We also prepared and applied "Safety Test".
HPLC method for TDM, and ELISA method for BDNF measurements were used consecutively.

Results:

In comparison to healthy participants, epileptic participants had lower marriage rate
(p=0.049), education level (p˂0.001), alcohol use (p=0.002). BDNF levels were higher in patients
with focal epilepsy (p=0.013) and in those with higher education level (p=0.016). There were negative
correlations between serum BDNF levels and serum ZNS levels (p=0.042) with LTGpolytherapy,
serum MHD levels (a 10-monohydroxy derivative of OXC, p=0.041) with OXCmonotherapy.
There was no difference in BDNF according to monotherapy-polytherapy, drugresistant
groups, regarding seizure frequency. There was a positive correlation between total health
status and QoL (p˂0.001). QOLIE-31 overall score (OS) was higher in those with OXCmonotherapy
(76.5±14.5). OS (p˂0.001), seizure worry (SW, p=0.004), cognition (C, p˂0.001),
social function (SF, p˂0.001) were different in the main groups. Forgetfulness was the most common
unwanted effect.

Conclusion:

While TDM helps the clinician to use more effective and safe NADs, BDNF may assist
in TDM for reaching the therapeutic target in epilepsy.

Authors: Fedakâr Atiye
Published: March 2019

Objective:

Maternal vitamin D deficiency is an important risk factor that causes infantile rickets in the neonatal and infantile period. The aim of this study was to review the prevalence, clinical characteristics, and treatment of vitamin D deficiency and the follow-ups with infants and their mothers by the neonatal intensive care unit of Afiyet Hospital in Turkey.

Methods:

Calcium (Ca), phosphorus (P) and 25 (OH) vitamin D were studied and prospectively recorded in infants and their mothers detected to have hypocalcemia during routine biochemistry tests performed on the third postnatal day of the patients follow up and treated with different diagnoses.

Results:

A total of 2,460 infants were admitted into the neonatal intensive care unit between August 2014 and January 2018. Of the infants included in the study, 324 (66.1%) were male and 166 (33.8%) were female, and 366 (74.6%) of them had been delivered by cesarean section (C/S), 124 (25.3%) of them had been delivered by Normal Spontaneous Delivery (NSD). Hypocalcemia was detected in 490 (19.9%) of the infants. In a total of 190 (38.7%) infants and 86 mothers (17.5%), the levels of 25 (OH) vitamin D were found to be below the laboratory detection limit of <3 ng/ml. When vitamin D deficiency + insufficiency is assessed by season, 151 of them were found to be in summer (30.99%), 118 in spring (24.18%), 117 in the winter season(23.87%), and 93 in autumn(18.97%), respectively. There was a statistically significant positive correlation of 78.7% between the vitamins D values of the mothers and the infants (p: 0.000, p<0.05).

Conclusion:

This study conducted that a positive correlation of between the vitamin D values of the mothers and the infants. In order to prevent maternal vitamin D deficiency, the appropriate dose of prophylaxis providing optimal levels of vitamin D and should be given by according to the levels of 25 (OH) D vitamin during pregnancy.
A Study on Effect of Sol Aging Time on Optical Properties of ZnO Thin Films: Spectroscopic Ellipsometry Method
Authors: Aghkonbad Ehsan Motallebi , Aghgonbad Maryam Motallebi , Sedghi Hassan
Published: March 2019

Background:

Due to wide band gap and large excitonic binding energy, being inexpensive,
abundance in nature and easy synthesis ZnO is a promising candidate in many applications such as solar
cells.

Experimental:

In the current work a series of ZnO thin films were deposited on glass substrates using
sol-gel method to investigate the change in optical behavior of the film with sol aging time (asprepared,
8, 16, 24 and 32 hours) and the annealing temperature (300ᵒC and 500ᵒC). The optical properties
of thin films were explored using spectroscopic ellipsometry method including the real and imaginary
part of refractive index, real and imaginary part of dielectric function and band gap energy of
the layers in the 300-900 nanometer wavelength range.

Results:

It can be deduced from the results that sol aging time and annealing temperature, affect the optical
properties of the samples. Using single oscillator energy model of Wemple and Di Domenico parameters
such as free charge carrier concentration ratio to effective mass, and plasma frequency, were calculated.

Conclusion:

The films prepared using 24 h aged solution, had the highest transmittance and the largest
band gap energy.
Burrows Wheeler Transform and Wavelet Tree Based Retrieval of Genome Sequence in an Indexed Genome Database
Authors: Kumar Sanjeev , Agarwal Suneeta , Ranvijay
Published: March 2019

Background:

New generation sequencing machinery such as Illumina and Solexa can
generate millions of reads from given genome sequence on a single run. There is a need for suitable
data structure, efficient with respect to memory as well as time to align these enormous reads into
reference genome. There are a number of existing techniques of indexing and reads alignment, such
as MAQ, Bowtie, BWA, BWBBLE and Kart. Memory efficient versions of these techniques are 10-
20% slower than their respective normal versions.

Objective:

A new approach for efficient indexing and retrieval of large genomic data.

Methods:

In this paper, we propose an efficient method based on Burrows Wheeler Transform and
Wavelet Tree (BWIT) for genome sequence indexing and reads alignment. Both types of alignments
(exact and approximate) are possible by the proposed approach (BWIT).

Results:

The performance of BWIT is experimentally found to be better than existing ones with respect
to both memory and speed. Experimental work shows that proposed approach performs best in
case of protein sequence indexing. All the existing read alignment approaches depend upon the size
of index used. In general, time required increases with reduction in index size used. Experiments
have been done with Bowtie, BWA & Kart by taking index size as 1.25N, 1.05N, .98N, where N is
the size of the text (reference genome). In our approach BWIT index size is .6N which is lesser than
index size used in all other approaches. It is observed that even using smallest index size alignment
time in our approach is least.

Conclusion:

An innovative indexing technique is presented to address the problem of storage,
transmission and retrieval of large DNA/Protein Sequence data.
Codeine Addiction and Internet Forum Use and Support: Qualitative Netnographic Study
Authors: Lee Eleanor , Cooper Richard J
Published: March 2019

Background

The use of codeine as an analgesic is well-recognized, but there are increasing concerns that for some individuals continued use may lead to misuse, dependence, and fatalities. Research suggests that those affected may represent a hard-to-reach group who do not engage with formal treatment services.

Objective

This study sought to explore the experiences of people with self-reported addiction to codeine and, specifically, how a social media forum is used to communicate with others about this issue.

Methods

Using a qualitative netnographic methodology, the social media forum Mumsnet was used, with permission, and searches were undertaken in 2016 of any posts that related to codeine and addiction. A total of 95 relevant posts were identified; a purposive sample of 25 posts was selected to undertake subsequent six-stage thematic analysis and development of emerging themes. These 25 posts were posted between 2003 and 2016 and comprised 757 individual posts.

Results

Individuals created posts to actively request help in relation to usually their own, but occasionally their partner’s or relative’s, problems relating to codeine use and self-reported “addiction.” Varying levels of detail were provided in narratives of problematic codeine use. There were both positive and negative descriptions of side effects emerging, problems experiencing withdrawal, and failed attempts to discontinue codeine use. Mainly positive and supportive responses to posts were identified from those with either self-reported health profession experience or lay respondents, who often drew on their own experiences of similar problems. Treatment advice emerged in two main ways, either as signposting to formal health services or to informal approaches and often anecdotal advice about how to taper or use cold turkey techniques. Some posts were more critical of the original poster, and arguments and challenges to advice were not uncommon. Shame and stigma were often associated with users’ posts and, while there was a desire to receive support and treatment advice in this forum, users often wanted to keep their codeine use hidden in other aspects of their lives. Distinctly different views emerged as to whether responsibility lay with prescribers or patients. Some users expressed anger toward doctors and their prescribing practices.

Conclusions

This study provides a unique insight into how a public internet forum is used by individuals to confirm and seek support about problematic codeine use and of the ways others respond. The pseudonymous use of internet forums for such information and variation in treatment options suggested by often lay respondents suggest that increased formal support and awareness about codeine addiction are needed. There may be opportunities for providing further support directly on such online forums. Improvements in prescribing codeine and in the over-the-counter supply of codeine are required to prevent problematic use from occurring.

ESTE ARTÍCULO EXAMINA LOS ORÍGENES DE LOS TESTIGOS DE JEHOVÁ EN MÉXICO, DESDE LA ORGANIZACIÓN DE SU PRIMERA CONGREGACIÓN EN LA CIUDAD DE MÉXICO EN 1919 HASTA LAS GRANDES ASAMBLEAS QUE REALIZARON EN 1944. TAMBIÉN SE OCUPA DE DOS MOVIMIENTOS RELIGIOSOS QUE SE ESCINDIERON DE LOS TESTIGOS: EL GRUPO ORGANIZADO EN TORNO AL TEMPLO "EL ÁNGEL JEHOVÁ", FORMADO POR LOS SEGUIDORES MEXICANOS DEL LÍDER RELIGIOSO SUIZO ALEXANDRE FREYTAG; EL OTRO ES LA EFÍMERA ASOCIACIÓN NACIONAL DE ESTUDIANTES DE LA BIBLIA. TAMBIÉN PROPONE QUE LOS TESTIGOS DE JEHOVÁ, UNA MINORÍA RELIGIOSA NUEVA Y DE ORIGEN EXTRANJERO, PUDO IMPLANTARSE EN MÉXICO GRACIAS A QUE APROVECHÓ LAS OPORTUNIDADES QUE LE BRINDÓ EL CONFLICTO ENTRE LA IGLESIA Y EL ESTADO, ASÍ COMO LA PROTECCIÓN QUE LOS GOBIERNOS REVOLUCIONARIOS OTORGARON A LAS ORGANIZACIONES CRISTIANAS NO CATÓLICAS.

ESTE ARTÍCULO ANALIZA LA FORMACIÓN Y LA CONDICIÓN POLÍTICA DE LOS POBLADOS DE HACIENDA Y SU LUCHA POR OBTENER EL ESTATUTO DE MUNICIPIOS Y PUEBLOS EN SAN LUIS POTOSÍ. DICHO ESFUERZO, EXPLICA, TENÍA EL OBJETIVO DE ACCEDER A LOS DERECHOS CORPORATIVOS DE QUE HABÍAN ESTADO EXCLUIDOS, TALES COMO EL INGRESO A TIERRAS DE USO COMÚN Y LA CONFORMACIÓN DE SUS PROPIOS AYUNTAMIENTOS. MUESTRA CÓMO LA LEY LERDO, QUE PROHIBÍA A LOS PUEBLOS Y AYUNTAMIENTOS LA POSESIÓN Y ADMINISTRACIÓN DE BIENES COMUNALES, AFECTÓ A LOS POBLADOS DE HACIENDA DE SAN LUIS POTOSÍ QUE SE ERIGIERON COMO MUNICIPIOS EN ESTA ÉPOCA, PARTICULARMENTE EN SU PROPÓSITO DE OBTENER TIERRAS COMUNALES PARA INDEPENDIZARSE DE LAS HACIENDAS EN QUE SE ENCONTRABAN.

EL TEXTO ABORDA UNA DE LAS ETAPAS MÁS IMPORTANTES EN LA VIDA DEL PINTOR DAVID ALFARO SIQUEIROS, LA QUE TRANSCURRIÓ MIENTRAS ESTUVO EXILIADO EN LAS CIUDADES DE LOS ÁNGELES, MONTEVIDEO Y BUENOS AIRES DURANTE 1932 Y 1934 EN NUEVA YORK EN 1936 Y POR ÚLTIMO A RAÍZ DE SU PARTICIPACIÓN EN EL ATENTADO EN CONTRA DE LEÓN TROTSKY EN 1940, EN LA CIUDAD CHILENA DE CHILLÁN, DE 1941 A 1943. LA AUTORA PROPONE QUE ESTE PERIODO NO SÓLO SELLÓ DE MANERA PERMANENTE LA RELACIÓN ENTRE LA CARRERA ARTÍSTICA DE SIQUEIROS Y SU ACTIVIDAD POLÍTICA, SINO QUE LES DIO, EN SUS CONTENIDOS E IMPACTO, UN AMPLIO CARÁCTER INTERNACIONAL Y TRANSCULTURAL. ANALIZA LOS ANTECEDENTES DE LA LABOR ARTÍSTICOPOLÍTICA DE SIQUEIROS Y SU REPERCUSIÓN EN LA FUNDACIÓN DE BLOQUES DE MILITANTES DEL PARTIDO COMUNISTA PROVENIENTES DEL ÁMBITO ARTÍSTICO.
La logística del ejército federal: 1881-1914
Authors: RAMÍREZ RANCAÑO MARIO
Published: March 2019

EN PLENA REVOLUCIÓN MEXICANA OCURRIÓ UN HECHO INSÓLITO. EL LLAMADO "EJÉRCITO FEDERAL", PREPARADO PARA LA GUERRA, FUE DERROTADO POR OTRO, EL "EJÉRCITO REVOLUCIONARIO", SURGIDO AL CALOR DE LA LUCHA ARMADA. QUÉ FUE LO QUE SUCEDIÓ. QUÉ FUE LO QUE FALLÓ. DESDE NUESTRO PUNTO DE VISTA, LO QUE FALLÓ FUE LA LOGÍSTICA MILITAR IMPLEMENTADA POR PORFIRIO DÍAZ Y MANTENIDA POR FRANCISCO I. MADERO. AL ASCENDER AL PODER EN FEBRERO DE 1913, VICTORIANO HUERTA BUSCÓ CORREGIR LAS COSAS, PERO FUE DEMASIADO TARDE. AUMENTÓ EL TAMAÑO DEL EJÉRCITO Y LO DISTRIBUYÓ EN FORMA MÁS RACIONAL POR TODO EL PAÍS, PERO LA REVOLUCIÓN SE HABÍA TORNADO INCONTROLABLE. LOS GENERALES, PROFESIONALES EN EL ARTE DE LA GUERRA, FUERON HUMILLADOS Y SUFRIERON UNA DERROTA TRAS OTRA. POR SU PARTE, LA TROPA ASUMIÓ UNA CONDUCTA INESPERADA. EN LA PRIMERA OPORTUNIDAD DESERTABA. A FINAL DE CUENTAS, EN AGOSTO DE 1914, EL EJÉRCITO FEDERAL CARGÓ CON LA DERROTA Y FUE DISUELTO.

La inestibilidad político-militar durante la primera república central, 1835-1839. La lógica del pronunciamiento en la figura del general José Urrea
Authors: PALOMO GONZÁLEZ GERARDO
Published: March 2019

EL ANÁLISIS DESARROLLADO EN ESTE TRABAJO SE UBICA EN UN BREVE PERIODO DE LA HISTORIA POLÍTICA DEL MÉXICO INDEPENDIENTE (1835-1839) CARACTERIZADO POR UN CAMBIO RADICAL EN LA FORMA DE GOBIERNO, AL PASAR DE LA REPÚBLICA FEDERAL A UN RÉGIMEN CENTRALISTA, Y POR LA OLEADA DE PRONUNCIAMIENTOS EN FAVOR DE LA REPÚBLICA FEDERAL QUE SE MANIFESTÓ ENSEGUIDA. SE TRATA DE UN MOMENTO HISTÓRICO QUE BIEN PODEMOS CARACTERIZAR EN TÉRMINOS DE CRISIS POLÍTICA Y CUYO ANÁLISIS NOS MUESTRA, EN SÍNTESIS, QUE UNA DE LAS PRINCIPALES CAUSAS DEL PRONUNCIAMIENTO COMO PRÁCTICA CONSUETUDINARIA DE LA ÉPOCA FUE LA FALTA DE LEGITIMIDAD POLÍTICA TANTO DE LA FORMA DE GOBIERNO COMO DE LA ADMINISTRACIÓN GUBERNAMENTAL MISMA.

La fundamentación del saber histórico en el siglo XX: inves tigación social, metodología y racionalidad operativa
Authors: Betancourt Martínez Fernando
Published: March 2019

El presente artículo busca mostrar el proceso de transformación de la disciplina histórica a lo largo del siglo XX. Este proceso afectó en dos aspectos al saber histórico: introdujo una pérdida de centralidad teórica que anteriormente defi nía su naturaleza cognitiva y produjo una diversidad de estilos y modalidades de investigación, lo que signifi có una reconversión de su orden metodológico. La tesis que sostiene el autor considera que dicha transformación puede explicarse atendiendo a la relación compleja que la historia entabló con el campo de la investigación social.

El apostolado educativo congregacionista francés y la cons­trucción nacional en México: una aproximación ejemplar a la historia religiosa de las relaciones internacionales
Authors: Foulard Camille
Published: March 2019

Este artículo tiene como objetivo presentar las problemáticas de la implantación misionera congregacionista francesa contemporánea en México, en un momento que no sólo remite a la historia religiosa y misionera tal como pudo ser descrita por la historiografía tradicional europea. Las dificultades a las cuales se enfrentaron las congregaciones especializadas en la docencia para difundir su obra en la primera mitad del siglo xx, también deben ser analizadas a partir de los dos contextos nacionales mexicano y francés caracterizados por el desarrollo de la laicización y de la secularización de la sociedad y en los cuales el tema de la educación se volvió el principal vector para imponer proyectos de sociedad opuestos.

'Amanecer paisano y dormir soldado...' Resistencias frente al reclutamiento y el servicio militar en la ciudad de México (1824-1858)
Authors: Ceja Andrade Claudia
Published: March 2019

A través de la confrontación de sumarios militares por los delitos de abandono de guardia y deserción, hojas de filiación, prensa y demás fuentes primarias, en este artículo se reflexiona sobre algunas de las respuestas que la población masculina llevó a cabo para evadir tanto el reclutamiento como el servicio militar durante las primeras décadas del siglo XIX. En el trabajo se dará cuenta de las ideas y creencias que se tenían sobre la conscripción, especialmente, la forzada. El objetivo específico no sólo es demostrar el tipo de tácticas de resistencia de reclutas y soldados, sino también reflexionar en el hecho de que estos mecanismos implementados “desde abajo” dieron forma a la dinámica militar.
¿De quién es la diplomacia pública? El rol del Departamento Autónomo de Prensa y Publicidad (DAPP) en la propaganda exterior cardenista
Authors: Dümmer Scheel Sylvia
Published: March 2019

El artículo explora el rol que tuvo el Departamento Autónomo de Prensa y Publicidad, creado por Lázaro Cárdenas para unificar todas las labores de propaganda estatal bajo un solo organismo centralizado, sobre la diplomacia pública de México entre 1937 y 1939. Debido a que su creación vino a interrumpir la larga labor que, en ese ámbito, realizaba la Secretaría de Relaciones Exteriores, el análisis se centra en la interrogante de sobre cuál organismo debiera recaer la propaganda exterior de la nación, ¿sobre aquél que se encarga de las comunicaciones del gobierno, o sobre la dependencia responsable de las relacionas internacionales del país? Para ello, se profundiza especialmente en el desafío que representó para el DAPP considerar la mediación cultural que requiere la diplomacia pública, y en los esfuerzos de la SRE por mantener cierto control sobre dicha labor. 
El amargo exilio de Victoriano Huerta y sus seguidores en España: 1914-1920
Authors: Ramírez Racaño Mario
Published: March 2019

A la renuncia de Victoriano Huerta a la Presidencia de la República ocurrida el 15 de julio de 1914, gran parte del personal político y militar salió del país, y se refugió en los Estados Unidos, Cuba, y en menor medida en España y Francia. Huerta se exilió en España, al igual que tres ex secretarios de Guerra y Marina, cinco miembros de su gabinete, y algunos intelectuales de prestigio. Debido a que España fue uno de los países cuyo gobierno reconoció a Huerta, los recién llegados supusieron que recibirían un trato especial, lo cual no fue así. Hubo hostilidad, atribuida a los estragos causados por la revolución mexicana a las propiedades españolas, indiferencia, falta de empleos, sin faltar pugnas entre ellos. Casi al mismo tiempo estalló la primera guerra mundial, lo cual agravó la situación de los exiliados. Su situación llegó al grado de que, a los pocos meses de haber llegado a la madre patria, casi todos la abandonaron y regresaron al nuevo mundo, en especial a los Estados Unidos.
POTASSIUM-INTERCALATED MANGANESE DIOXIDE AS LITHIUM-ION BATTERY CATHODES: A DENSITY FUNCTIONAL THEORY STUDY
Authors: Ismail Agus , Prabowo Herry Agung , Alfaruqi Muhammad Hilmy
Published: March 2019

It is obvious to harness the intermittent renewable energy resources, energy storage applications, such as a lithium-ion battery, are very important. α‒type MnO2 is considered as an attractive cathode material for lithium-ion battery due to its relatively large (2 × 2) tunnel structure, remarkable discharge capacity, low cost, and environmental benignity. However, low intrinsic electronic conductivity of α‒type MnO2 limits its full utilization as a cathode for a lithium-ion battery. Therefore, studies to enhance the α‒type MnO2 properties are undoubted of great interest. While previous computational studies have been focused on pristine α‒type MnO2, in the present report, we present the theoretical research on potassium-intercalated α‒type MnO2 using first principle Density Functional Theory calculations for the first time. Our results showed that potassium-intercalated α‒type MnO2 improved the electronic conductivity which beneficial for energy storage application. The structural transformation of potassium-intercalated α‒type MnO2 upon lithium insertion are also discussed. Our results may open the avenue for further utilization of potassium-intercalated α‒type MnO2 materials for not only the lithium-ion battery but also other type energy storage systems.
¿Se puede “secuestrar” carbono a la vez que se conserva la biodiversidad de los bosques? Revisión de la evidencia científica y recomendaciones
Authors: Vincent Andrea G.
Published: March 2019

Los bosques tropicales almacenan gran parte del carbono terrestre en su biomasa e iniciativas como REDD+ (Reducción de Emisiones por Deforestación y Degradación del Bosque y más) buscan evitar la liberación de este carbono por medio de la protección de los bosques. Sin embargo, no todos los bosques ricos en carbono son ricos en biodiversidad. Aquí, sintetizo la información existente sobre la relación entre la cantidad de carbono almacenado y la biodiversidad de árboles en bosques tropicales, enfatizando la importancia de que REDD+ explícitamente maximice la conservación de la biodiversidad, no solo del carbono.
