Published: February 2020

Objective. To obtain a first indication of the distribution and extent of manganese (Mn) contamination in Mexico City. Mn concentration and load in street dust were analyzed in order to reveal the most contaminated areas. Materials and methods. 482 samples of street dust were analyzed through inductively coupled plasma-optical emission spec­troscopy. The contamination factor (CF), the geoaccumula­tion index (Igeo) and the spatial interpolations of the kriging indicator were calculated. Results. A slight influence of anthropogenic activities is detected on the Mn content of street dust. The highest levels of pollution by concentra­tion (Igeo=uncontaminated to moderately contaminated) are grouped towards the city’s north (industrial) and center (commercial and high traffic) areas. The areas with the high­est Mn load were located towards the east and northwest areas (Igeo=moderately contaminated). Conclusions. These findings will serve as a baseline to assess future variations in Mn content in Mexico City’s environment.

Neutron Log Correction Charts for Borehole Conditions and Bed Thickness
Authors: Dewan J.T.
Published: February 2020

Published in Petroleum Transactions, Volume 207, 1956, pages 50–58.

An experimental setup is described whereby the responses on Neutron logging instruments have been determined opposite formations of different porosities and under various borehole conditions.

The results of these tests are presented in several charts which show how the Neutron log is affected by the following factors: hole diameter, casing, cement, salinity and weight of drilling mud, and position of logging tool with respect to the wall of the hole. The responses in the case of empty holes are also shown.

A chart is furthermore presented which shows the shapes of the Neutron log, as a function of logging speed and time constant, at the boundaries between two formations with different porosities. These were derived mathematically using as a basis laboratory determination of the shape of the curve under static conditions, i.e. at very low logging speed. Corrections for the readings made opposite thin beds are given by these computations. The correction is found negligible under usual logging conditions for beds thicker than about 4 ft.

Introduction

The Neutron log is used in borehole surveys both for the delineation of porous formations and for the quantitative estimation of their porosities.

It is common practice to calibrate the response of the Neutron log in terms of porosity values for each given geological unit by means of empirical comparisons between the deflections of the neutron curve and the porosity values given by the core analysis in a sufficient number of wells.

Usually, the plots of the porosity values vs Neutron log deflections show a definite trend. It is therefore possible to trace an average line across the plotted points. This average line constitutes a calibration curve which can be used to evaluate the porosities from the Neutron logs in the other wells drilled in the same region.
Theory of Dimensionally Scaled Models of Petroleum Reservoirs

Published in PetroleumTransactions, AIME, Volume 207, 1956, pages 118–127.

The dimensionless groups, to which the variables that govern the displacement of oil from reservoirs by liquids can be combined, are derived. Three types of displacement are considered, viz. cold-water drive, hot-water drive and solvent injection.

The derivation of the dimensionless groups is carried out by means of the relevant basic equations (inspectional analysis). The resulting sets of groups are afterwards completed by means of dimensional analysis. The form of the groups is given in such a way that they can be adapted to suit the various boundary conditions that are encountered in practice. The physical meaning of the groups is discussed. They have all been brought together on a chart, from which their mutual relation and their correspondence to related dimensionless groups in common use in other engineering sciences can be read off.

The limitations of dimensionally scaled model experiments as a useful tool for studying liquid flow in porous media, as occurring in oil reservoirs, are discussed.

" The use of models to study fluid mechanics has an appeal for everyone endowed with natural curiosity. What active boy has not played with ship and airplane models, or crude models of dam and drainage systems? Even in the most advanced technical engineering, such models play a fundamental and indispensable role.

" And yet in few departments of the physical sciences is there a wider gap between theory and practice, between scientific knowledge and the state of art, than in the use of models to study hydrodynamic phenomena."

Garrett Birkhoff

Introduction

Laboratory displacement experiments are extensively used to investigate, directly or indirectly, the production behavior of petroleum reservoirs. Such experiments are representative of the reservoirs as a whole, if they are carried out with models that are "properly scaled."
Comparison of Pressure Distributions During Depletion of Tilted and Horizontal Aquifers
Authors: Howard D.S. , Rachford H.H.
Published: February 2020

Published in Petroleum Transactions, Volume 207, 1956, pages 92–98.

In the withdrawal of fluids from tilted aquifers it is of value to be able to predict pressure patterns during the course of the pressure decline. As an example of this, in the displacement of fluids from oil reservoirs being produced by water-drive, prediction of the reservoir pressure is an important factor in fixing production rate. The prediction of pressure patterns in the depletion of an inclined aquifer has conventionally been made by solving the well known flow equations for the pressure patterns in a horizontal aquifer, and correcting these patterns for the pressure difference due to the hydrostatic head associated with the vertical distance between a point in the horizontal aquifer and the corresponding point in the tilted aquifer.

Inasmuch as the equation describing flow in tilted strata is different from that for horizontal flow, there was question as to the validity of the simple corrective procedure currently in use. To examine the magnitude of error made using this procedure, an inclined aquifer was chosen for which the error was expected to be large, and the equation for flow in this tilted stratum was solved numerically. The results of the conventional procedure of correcting the solution of the equation for horizontal flow was compared with the solution of the correct equation by studying the difference between predicted pressures by the two methods. Three forms of the hydrostatic head correction were studied.

The results for all three forms of the head correction are similar. The error in the approximate solution is quite dependent on the position of the horizontal aquifer with respect to the inclined one. The error is greatest at the producing end and increases with amount of fluid withdrawn. The magnitude of the errors is not large if a good choice is made for the position of the horizontal datum. The most satisfactory position for the datum in all cases is near or slightly about the mid-point of the inclined stratum. Use of the best approximate method studied with the best datum tested yielded predicted pressures in error no greater than 7 psi.
Water-Coning Before Breakthrough - An Electronic Analog Treatment
Authors: Karplus Walter J.
Published: February 2020

Published in Petroleum Transactions, AIME, Volume 207, 1956, pages 240–245.

By means of a finite difference expansion a fluid flow field in cylindrical coordinates with axial symmetry, is simulated by a network of electrical resistors. A series of DC analog computing units, connected to the network boundary corresponding to the free surface effectively adjust the network parameters to satisfy simultaneously Laplace's equation and the boundary conditions. The system automatically "relaxes" to the correct boundary shape in a fraction of a second. A detailed application of the method to the water coning problem in oil wells is presented.

Introduction

The water coning problem in petroleum production is a prime example of a class of problems known as free surface problems. A free surface arises in fluid flow regions when the shape of the boundary of a single phase flow region is affected in some manner by the pressure or potential gradients within the region. When there exists an interface of two fluids of different densities, the shape of this interface will be determined by the relative velocities of the two fluids and will therefore comprise a free surface. Other free surface problems of interest to petroleum engineers include the gas coning, water injection, and gravity drainage problems. In each case it is desired to predict the shape of the boundary of the oil zone as a function of the flow rate, the well penetration and the physical parameters and dimensions of the system.

Such problems do not lend themselves to the classical analytical treatments of boundary value problems because in this case the boundary of the potential field and the potential distribution within the field are interdependent and must be calculated simultaneously. A further difficulty arises from geometric considerations. Since the fluid flow is of the radial type in most cases, such effective methods as conformal transformation and the hodograph are not applicable. It is the purpose of this paper to present a method whereby free surface problems of this type may be solved rapidly to the desired order of accuracy by means of a combination of a network of electrical resistors and conventional analog computer units. The water coning problem is treated in some detail. Then the procedure for extending the technique to other free surface problems is indicated.
Scale Limitations in Potentiometric Model Construction

It is an accepted procedure to represent oil field displacement problems in which the pressure is relatively constant by a potentiometric model. Variations in reservoir permeability thickness product are represented in the model by proportional variations in electrolyte depth.

It is shown that significant errors are present wherever these variations are of such magnitude that the consequent differences in the electrolyte depth in the model or any regions therein are appreciable in comparison with their respective horizontal dimensions.

To demonstrate the order of magnitude of this error, a hypothetical linear oil field in which permeability varies linearly with distance was treated both analytically and by potentiometric model. The results obtained from the model are compared with the exact solution for various configurations of linear geometry. Deviations in flow times up to 11 per cent were observed. It is confirmed that these discrepancies can be reduced by increasing the areal scale and/or decreasing the vertical scale of the model.

It is the purpose of this work to assist in the design of potentiometric models by indicating the relationship between this error and the chosen scale factors.

Introduction

The fundamental geometrical criterion which determines whether the pressure distribution in an oil or gas reservoir may be simulated in a conventional potentiometric model is the requirement that all reservoir parameters be constant along any vertical line between its upper and lower boundaries. This situation never obtains exactly; nevertheless, it is usually assumed that there is no permeability stratification within the section of interest, that all wells completely penetrate the sand, that there are no gravitational effects, and that variations in thickness of the sand are small compared to the horizontal extent of the field. In these ways the reservoir problem is reduced to two dimensions in which there is no variation of pressure in the vertical direction within the limits of the sand.
The Use of Barium Hydroxide in Drilling Muds
Authors: Darley H.C.H. , Generes R.A.
Published: February 2020

Published in Petroleum Transactions, AIME, Volume 207, 1956, pages 252–255.

Laboratory tests showed that at elevated temperatures a reaction takes place between all metal hydroxides and clay muds, which results in a thickening or solidifying of the mud, the extent of which depends on the nature of the ingredients. Calcium hydroxide gave the strongest solidification whereas barium hydroxide only caused a mild thickening, indicating that the use of barium hydroxide muds instead of lime muds would be a good way of preventing high-temperature solidification. It was found possible to prepare barium mud in the laboratory with caustic soda and a thinner in the same manner as lime muds, and these barium muds had the same or better toleration of high solids content, resistance to salt contamination, and low gel strengths as the corresponding lime muds.

Three field trials have been made with barium mud. The principal difficulty encountered was in determining the correct proportions of the tourly treatments required to maintain low gel strengths. A satisfactory system was finally developed, and low gels were maintained throughout the third test. The wells on which the trials were made were not carried deep enough to test the resistance to solidification adequately, but oven tests at 350° F were made periodically and no tendency to solidification was noted except immediately after severe cement contamination had introduced excessive amounts of calcium into the system.

Although barium hydroxide costs considerably more than lime, the total mud costs were as low, and on the last well significantly lower, than the average cost of lime mud wells drilled in the vicinity.

Introduction

The advantages of repressing dispersion and hydration of clay cuttings carried in the mud, particularly when drilling through thick clay formations, are well recognized. This repression is generally achieved by the use of lime, and lime muds have in consequence the desirable characteristics of high toleration of solids, low thixotropy, and good resistance to contamination. They have, however, the disadvantage of high-temperature solidification. This phenomenon has been described in detail by Gray et al., who have shown that it is the result of a chemical reaction between the hydroxides and the clay minerals. The work described in this paper was undertaken to find a substitute for lime which would not cause this solidification.

Published: February 2020

Background Problem-based learning (PBL) provides an encouraging learning environment to develop generic, research, and creative thinking skills, which have been identified as essential for facing 21 st century challenges. However, how PBL is implemented into a curriculum can be critical for achieving these outcomes. This study explores the effects of shifting the implementation of PBL from a PBL-module integrated into traditional subjects to full interdisciplinary PBL-courses in undergraduate health sciences students. Methods This study involved 651 participants, with 364 taking the PBL-module and 287 taking the PBL-courses. Students’ and tutors’ perceptions about the acquisition of the skill set as well as their satisfaction with the learning experience were collected through surveys and compared in both models. Results Results showed that in interdisciplinary PBL-courses, both students and teachers had the perception that both skills improvement and PBL usefulness were better, and overall were more satisfied with the course. A strong correlation was observed between the acquisition of generic and research skills and the perception of PBL usefulness and overall satisfaction with the experience. The study also showed how creative skills are developed during the different PBL phases. Conclusions This study provides new evidence on PBL characteristics that favour the development of these skills.

Published: February 2020

Background: The objective of this study was to evaluate and compare the validity and accuracy of the Willems, Demirjian and Nolla methods in predicting chronological age in a Spanish ethnicity population. Methods: A sample of 604 orthopantomographs of Spanish children aged 4 to 14 years was evaluated by two independent evaluators. Descriptive statistics were applied to calculate the chronological age and dental age, presenting the mean and standard deviation. The difference between dental age and chronological age was calculated for each method. A positive result indicated an overestimation and a negative figure indicated an underestimation. The Wilcoxon test for paired data and Spearman's correlation coefficient were applied by age groups and gender to compare the chronological age and dental age of each method (that of Willems, Demirjian and Nolla). Statistical tests were performed at a 95% confidence level. Results: The interexaminer agreement was 0.98 (p = 0.00), and the intraexaminer agreement was 0.99 (p = 0.00). The Willems method significantly overestimated the age of boys (0.35 years (0.93)) and girls (0.17 years (0.88)). The Demirjian method significantly overestimated the age of boys (0.68 years (0.95)) and girls (0.73 years (0.94)). The Nolla method significantly underestimated age in boys (0.44 years (0.93)) and girls (0.82 years (0.98)). Conclusions: In the Spanish population, the use of the Demirjian method for legal and medical purposes is frequent. This study reveals that the Willems method is more appropriate due to its greater precision in estimating dental age.

Published: February 2020

Introduction Psoriatic arthritis (PSA) is a form of immune-mediated inflammatory arthritis. Studying the gut microbiota of PSA patients may offer new insights into the pathophysiology of this inflammatory joint disease. We designed a prospective study to examine gut microbiome from patients with PSA, primarily with enthesitis and dactylitis, and compared the data with undifferentiated arthritis patients (NO PSA), without enthesitis or dactylitis.Methods We enrolled nine PSA patients and 10 NO PSA patients in this study. The fecal samples were investigated by using 16S rRNA amplicon sequencing, followed by bioinformatics and statistical analyses. Results None of the available objective clinical laboratory data could differentiate PSA from the NO PSA subgroup. The microbiota result shows that Family: XIII_AD3011 is significantly higher in NO PSA patients than PSA patients’ stool samples (p=0.039). Megasphaera elsdenii in the PSA was 10000 times higher than in the NO PSA group.Conclusion Our results demonstrated high intra-group homogeneous and high inter-group heterogeneous microbiota. The clinical symptoms of either enthesitis or dactylitis link to the specific microbiota in the current study. In the future, a larger cohort and thorough biochemical study is needed for confirmation.

The general objective of this study is to determine the appropriate corporate development strategy of Johnson Johnson to strengthening the position in the area of infectious diseasese to help the mankind to get the best anti infectious drugs with the affordable price. Infectious diseases is a second leading killer worldwide, it is consist of HIV/ AIDS, TB, Hepatitis C, etc. Infectious diseases have caused an unprecedented global health crisis. The Asia division of Johnson Johnson plans to invest in open innovation through more research partnerships and collaborative efforts that connect the medical and academic communities to its RD centers especially in infectious disease. The data used in this research is data result of observation, literature study and interviews with senior executives and consultants who  handle comparable decision of JohnsonJohnson. The data show that alliance is preferrable. High uncertainty within the environment is the most influencing factor to determine this choice. Due to the industry nature, many RD collaborations in developing particular drugs are established. By defining the proper governance structure the collaboration can limit the risk of losing in the learning race and core competencies spillover while obtaining the knowledge access to the counterparty. The Strategic alliance between Johnson Johnson and Cipla Inc can help them toughen the corporate development strategy. Because of their similarities in the production of anti-infectious drugs, they can cooperate to penetrate emerging markets and do several RD collaborations to create a competitive advantage.

Background:

Hypersensitization to nickel is one of the most common contact allergies in the modern world and it is considered to be a major cause of contact dermatitis, especially for hand eczema.

Objective:

The aim of this paper is to describe many faces of the nickel allergy and to find out different diagnostic, potential strategies for treatment and prevention in hypersensitized patients. A personal clinical experience with practical clinical cases of contact dermatitis to nickel has also been presented.

Methods:

Electronic databases on this topic was carried out using PubMed-Medline.

Results:

The literature review identified many articles reporting for nickel contact allergy and pointing the metal as number one allergen in the frequency of positive skin patch test reactions in a large population worldwide. Herein, a summary of the current understanding and evidence on nickel allergy with practical approach and proposed recommendations to the dermatologist, general practitioner, and the allergist were prepared.

Conclusions:

The prevalence of nickel allergy represents an important socio-economical and health issue. Metal is one of the most common sensitizing agents worldwide. The morbidity due to this metal represents the allergic contact dermatitis and it is constantly growing in many countries. There are also cases of systemic allergic contact dermatitis, where they could be easily misdiagnosed as adverse drug reactions, which lead to delay of the correct diagnosis and inappropriate treatment.
A (Speculative) View on Allicin and Primary Metabolism: An Additional Way to Affect Cell’s Physiology
Authors: Sarfraz Muhammad , Gruhlke Martin C.H.
Published: February 2020

Background:

Allicin from garlic is known for different medical uses for centuries. One important explanation for these effects is the chemical reactivity of allicin as a thiosulfinate towards thiol-groups and the modification of thiol-groups by thioallylation.

Objective:

It has been shown that thioallylation can inhibit the enzymatic function of proteins. In different organisms, the thioallylated proteins upon allicin treatment have been examined. It was found, especially in human T-cell lymphocytes (Jurkat-cells), that the glycolysis is a major target for allicin. Here, we briefly discuss that affecting the primary metabolism is a possible part of allicin’s physiological functions and might be, both from therapeutic and nutraceutical view, of particular interest for the application of allicin as an active principle of freshly damaged garlic.

Conclusion:

This might, in summary, explain a possible further mode of action of allicin on cells by changing the metabolism as the central life process and thus influencing the overall structure of the physiological processes in the cell, which can lead to the multitude of consequences caused by allicin.
Mitología jurídica en nuestra América: resignificar el discurso jurídico para un derecho intercultural
Authors: Fonseca Sandoval Jose Daniel
Published: February 2020

El presente artículo tiene como propósito la crítica del discurso jurídico moderno en Nuestra América, desde la perspectiva de la mitología jurídica. La tesis principal consiste en que la ciencia jurídica, al negar o ignorar su fundamento mítico, encubre las relaciones desiguales de poder y de saber que definen y construyen el discurso del derecho. Desde una posición teórico-crítica nuestroamericana, se revisará, en primer lugar, la concepción del derecho como discurso y campo social, así como la emergencia de las zonas del no-ser. En segundo lugar, se abordará el fundamento mítico de la ciencia jurídica y dos ejemplos de configuraciones míticas del discurso del derecho. Finalmente,  el artículo concluye que, para realizar un derecho intercutural, decolonial y para la emancipación, se necesita una apertura discursiva de mitos y cosmologías, acompañada de la reivindicación de saberes jurídicos y derechos alternativos.

Revisiting the ‘Recognition’ of the Palestinians’ Right to Self-Determination: Peoples as Territories
Authors: Sakran Shadi
Published: February 2020

‘[B]ehind every Palestinian there is a great general fact: that he once – and not so long ago– lived in a land of his own called Palestine, which is now no longer his homeland.’ The question of whether the Palestinian people, as a people, are entitled to exercise the right to external self-determination has been highly controversial over the years. Divided scholarly research, particularly regarding the attitude of the State of Israel which, at time of writing, has not yet explicitly recognized the Palestinian peoples’ right to emerge as an independent State, serves as evidence to this claim. In 2004, the ICJ in the Wall Advisory Opinion observed that the Palestinians’ right to self-determination is no longer in issue. This observation serves as the benchmark for this paper to revisit the identification of a people under international law. This paper critically examines whether constitutive and declaratory theories of recognition in statehood can assist in understanding the concept of a people in the law of self-determination. While concluding that neither theory of recognition is satisfactory, this paper argues that application of the right to self-determonation, within and beyond the colonial context, is inevitably linked to the territory peoples inhabit. Although the relationship between peoples and territories should come as no surprise, the key element in determining a people is not based on the people but on the status of the territory they inhabit.

BACKGROUND

As a critical driving power to promote health care, the health care–related artificial intelligence (AI) literature is growing rapidly.

OBJECTIVE

The purpose of this analysis is to provide a dynamic and longitudinal bibliometric analysis of health care–related AI publications.

METHODS

The Web of Science (Clarivate PLC) was searched to retrieve all existing and highly cited AI-related health care research papers published in English up to December 2019. Based on bibliometric indicators, a search strategy was developed to screen the title for eligibility, using the abstract and full text where needed. The growth rate of publications, characteristics of research activities, publication patterns, and research hotspot tendencies were computed using the HistCite software.

RESULTS

The search identified 5235 hits, of which 1473 publications were included in the analyses. Publication output increased an average of 17.02% per year since 1995, but the growth rate of research papers significantly increased to 45.15% from 2014 to 2019. The major health problems studied in AI research are cancer, depression, Alzheimer disease, heart failure, and diabetes. Artificial neural networks, support vector machines, and convolutional neural networks have the highest impact on health care. Nucleosides, convolutional neural networks, and tumor markers have remained research hotspots through 2019.

CONCLUSIONS

This analysis provides a comprehensive overview of the AI-related research conducted in the field of health care, which helps researchers, policy makers, and practitioners better understand the development of health care–related AI research and possible practice implications. Future AI research should be dedicated to filling in the gaps between AI health care research and clinical applications.
