Városi közösségi kertek Magyarországon
Authors: Bársony Fanni 
Published: February 2020

A városi közösségi kertek („community garden”) külföldön több évtizedes múltra tekintenek vissza, Magyarországon néhány éve terjedtek el. A közjavak (commons) és városi közjavak (urban commons) tudományos irodalma a kerteket az önszerveződő és a megosztás gyakorlatait előtérbe helyező közösségeknek egy új, egyre nagyobb társadalomtudományos érdeklődést kiváltó típusába sorolja. Tanulmányomban elsőként áttekintem, hogyan kapcsolódnak a kortárs közjószágkutatások a közjavakkal kapcsolatos hagyományos elméleti keretekhez és a kertek példáján keresztül megpróbálom igazolni a nemzetközi irodalomban tett megállapításokat. A magyarországi kertekről gyűjtött empirikus tudást a kertekben folytatott terepmunkára és a kertek működtetése kapcsán felmerülő problémákat feltáró csoportos interjúra alapozom. Arra keresem a választ, hogy milyen típusú közjavakként interpretálhatók a városi közösségi kertek, mi jellemzi a közösségeiket az erőforráshoz való viszonyt illetően, pontosan milyen erőforrás áll a közösségi kormányzás fókuszában, és milyen megosztáson alapuló gyakorlatot követnek a kertközösségek. Munkámmal egyik célom betekintést nyújtani a magyarországi kertközösségek működésébe, másik pedig a kertek példáján keresztül reflektálni a városi közjavakról zajló tudományos diskurzusra. A kertek külső, intézményes környezete, valamint a működtetésükkel kapcsolatban felmerülő belső problémák és gyakorlatok jó kiindulópontként szolgálnak a városi közjavakkal kapcsolatos koncepcionális kérdések feltárásához. Terepkutatásom azt igazolja, hogy a városi közjavak esetében nem elég arra koncentrálni, mi a közös erőforrás és mik a hozzáférés feltételei, a közjavakat az őket működtető közösséggel összefüggésben kell vizsgálni, és az erőforrás mibenlétére, a használók és haszonélvezők körére is mint változó kategóriákra érdemes tekinteni. A közjavak nemcsak a jószágok típusaként, hanem társadalmi gyakorlatként is felfoghatók, és a közösségek különbözhetnek abban, mennyire engednek a megosztás gyakorlatainak.
Effectiveness of light emitting diode versus conventional phototherapy in neonatal hyperbilirubinemia: a hospital based observational study
Authors: Purkait Radheshyam , Mondal Manik 
Published: February 2020

Background: The most commonly used light sources in the conventional phototherapy units are compact fluorescent lamp (CFL), halogen spotlights and fiberoptic blankets. Recently light emitting diodes (LED) has emerged as better light source for phototherapy and almost replacing all the available conventional light sources. Comparative studies on the efficacy of LED versus conventional phototherapy are limited from India. That is why; this study was undertaken.Methods: 48 neonates of ≥35 weeks gestational age with hyperbilirubinemia were participated in this study. Among them, 24 neonates received conventional phototherapy and rest of them received LED phototherapy. The rate of fall of bilirubin levels at 6 hours and at completion along with total duration of phototherapy in both groups was measured. Results analysed by standard statistical methods.Results: LED phototherapy units showed higher rate of fall in bilirubin at six hrs (LED group: 0.38±0.05 mg/dl/hr versus conventional group: 0.30±0.04 mg/dl/hr, p<0.05) and after completion of therapy (LED group: 0.32±0.03 mg/dl/hr versus conventional group: 0.26±0.03 mg/dl/hr, p<0.05) compared to conventional group. Significant difference was documented in total duration of phototherapy in LED group (30.8±1.8 hours) when compared to conventional group (34.6±0.7 hours). None of the neonate showed phototherapy failure. Side effects were minimal and comparable in both the groups.Conclusions: The LED phototherapy units are more efficacious in terms of higher rate of fall of bilirubin levels and lesser duration of phototherapy compared to conventional phototherapy units.
Atypical pneumonia in an immunocompromised host
Authors: Shaylika Chauhan , Jawad Noor 
Published: February 2020

Pneumonia is a common complication of patient with lung cancer. Various Pathogens have been reported to cause pneumonia in such patients, commonly involved organisms include bacteria (e.g. S. pneumoniae, Klebsiella spp., P. aeruginosa, S. aureus), virus (e.g. CMV, varicella zoster virus, respiratory syncytial virus, parainfluenza and influenza viruses), fungi (e.g. histoplasmosis, cryptococcosis, pneumocystosis, Aspergillosis), opportunistic infections (e.g. Aspergillus, Pneumocystis jiroveci) and this list is progressively growing. Here authors are going to discuss a rare case of 61-year-old male patient of lung cancer suffering from pneumonia caused by Chryseobacterium gleum, Stenotrophomonas maltophilia and Actinomyces naeslundii and its management. Since these organisms are rarely known to cause pneumonia, so whenever we encounter such patients while authors consider common pathogens, authors should also keep in mind rare organisms especially when the pt fail to respond standard treatment.

Published: February 2020

Background: To evaluate long term efficacy and complications of Mitrofanoffs procedure in patients with bladder dysfunction.Methods: Authors retrospectively reviewed the medical records of 51 patients who underwent construction of a continent catherisable channel (mitrofanoffs and monti) from 2009 till 2019 in our institution. Clinical findings and investigations result along with surgical techniques used were noted for these patients. Postoperative complications along with urinary continence and renal outcome were evaluated.Results: Mean age was 7 years and mean follow up was for 3 years. 27 patients were with neurogenic bladder and 24 with non-neurogenic bladder. The most common type of conduit was appendicovesicostomy (38) followed by illeal monti (12) and ureter (1). The most common stomal site was umbilicus (44) followed by right lower abdominal quadrant (6). Catherterizable conduit complications included stomal leakage in 3, mucosal prolapse at the stoma site in1 and an intra peritoneal leak requiring exploratory laprotomy and revision in1. Relative stomal continence was achieved in 98%. The preoperative serum creatinine & blood urea nitrogen (BUN) at the time of mitrofanoffs procedure at the last follow up after the procedure were sought and compared using Chi square test showed statistically significant improvement (p<0.01). No differences in outcome and complication rates were noted between different types of conduit, sites of implantation, or segments used for augmentation.Conclusions: Mitrofanoff is a safe and reliable procedure in children who are dependent on intermittent catherisation in developing countries. Appendicovesicostomy is our first option followed by yang -monti illeovesicostomy. While stomal continence is excellent patient education, family motivation and cost reduction are important factors for its lasting efficiency.

Technology Focus: Seismic (March 2020)
Authors: Egan Mark S. 
Published: February 2020

Technology Focus
Two years ago, in this column, I focused on new, exciting technology advances that were being made with the seismic method. Unfortunately, 1 year ago, I had to change the theme to the deepening economic downturn that had occurred in the industry. Happily, though, in this past year, we witnessed several examples of marriage between these two themes. In other words, necessity for survival in hard times provided the impetus for innovation.
For example, in one case of land seismic, the acquisition system was redesigned. This started with the stripping down of the nodal geophone, leaving only the very basic functionality that was needed. Ultimately, this led to a much lighter system, not only reducing power requirements but also the labor needed to deploy (and later retrieve) the ground equipment. In turn, this efficiency led to lower costs while still allowing advancement to the denser, spatial sampling enabled by higher channel counts.
In another case, success was achieved not through changes in technology but rather through changes in business strategy. Historically, when downturns occur, one of the first line items to be cut is the acquisition of new seismic programs. However, the strategy reported by one courageous company was to continue with its usual level of advanced seismic acquisition and processing, while saving costs by reducing the exploration drilling. This strategy of protecting the ability to identify future, high-quality prospects is what led to success.
Continued development of seismic applications occurred in many other disciplines, too, including unconventionals, microseismic, and imaging. This often took place through effective use of multidisciplinary teams and machine learning.
That discussion is supported by the three synopsized papers included in this Technology Focus section, as well as the three papers that are recommended for additional reading. Enjoy.

Model Studies for Production-Injection Well Conversion During Line Drive Water Floods

Introduction
In water flooding peripheral, center-to-edge, line-drive or water-encroachment patterns the question has arisen, "when should a producing well be converted to a water-injection well?". It is realized that, if the producing well is shut in when water breakthrough occurs, some oil could be left in an unswept area. Yet, operation to high water-oil ratios may require processing much additional water. If a well is shut in, "where should the unallowable be transferred?". A review of the literature indicates that very few data are available to the engineer to assist him in answering these questions. It is the purpose of this paper to present information which may be of value in selecting the flooding technique and the injection and producing wells and in scheduling injection and production rates.
Certain phases of these problems can be studied in the laboratory. The potentiometric model is well suited for studying many waterflooding problems. This model assumes that steady-state flow exists, that the mobility ratio is equal to one and that gravitational effects are neglected. The three-phase sand model also has been recognized as an effective means for studying certain reservoir problems. Both models were used in making the study reported here. This paper discusses seven cases utilizing various waterflooding techniques. Data for the first five cases were obtained on the potentiometric model. Data for Cases VI and VII were obtained by constructing and flooding an unconsolidated sand pack (a three-fluid-phase system) and by determining the swept area and cumulative oil recovery for various types of operations.

Apparatus and Procedure
The potentiometric model reservoir was 30 in. long X 10 in. wide by about 1/2 in. deep. Four wells were equally spaced in a line array along the lateral center line. (See Fig. 1.) Well No. 1 initially was an injection well for each of the patterns reported. The cases studied with the potentiometric model and sand model are described herein.

Abstract
A miscible displacement pilot using a slug of LPG driven by separator gas was conducted in the Cardium reservoir of the Pembina field. The injection pattern was a 10-acre, inverted, isolated five-spot. Upon completion of the LPG-gas phase, an experiment was conducted using a slug of water followed by gas.
Calculated performance of the pilot is compared with actual performance. Equations are developed to calculate the distribution of LPG into zones of varying permeability, to estimate the progress of the flood at different times in the various zones and to estimate gas rates after breakthrough. The analysis indicates that permeability stratification was a dominant factor in controlling oil recovery and that oil was completely displaced from the swept pore volume.
The results of the pilot indicated that miscible flooding is a practical means of pressure maintenance in this reservoir. The total recovery from the pilot area was good in spite of the early breakthrough of LPG. The effects of stratification were reduced by injecting a slug of water into the partially swept reservoir.

Introduction
The Pembina field, located in Alberta, is the largest oil field in Canada and one of the largest in the North American continent. The reservoir is a stratigraphic trap producing from the Cardium sand. Neither bottom water nor free gas has been found. The recovery of oil by the natural depletion mechanism has been estimated at 12.5 per cent.
Pressure maintenance studies of various areas have indicated that the recovery can be increased 2 1/2 times by water flooding, and a large area of the field is presently under water flood. However, reservoir studies of the North Pembina area indicated that miscible flooding might be competitive with water flooding. A pilot test was conducted to evaluate the performance of a miscible flood.
A Study of Gas-Cap Water Injection in a Peripheral Water Flood

Abstract
Peripheral water injection has been underway in the Sholem Alechem Fault Block "A" Unit, Stephens County, Okla., since 1955. In the engineering planning of the flood, it was recognized that maintenance of pressure in the large, dry gas caps was vitally necessary to prevent the loss of an estimated 27 million bbl of oil through saturation of the gas caps by the oil banks moving updip on the peripheral flood pattern. The development of an abundant, low-cost water supply and the rising cost of makeup-gas purchases indicated that gas-cap control by water injection was desirable from an economic standpoint, provided an effective water barrier could be placed without premature water breakthrough into downdip oil producers.
A laboratory model scaled to the existing reservoir conditions was constructed to evaluate the feasibility of gas-cap water injection. Model studies indicated thatwater injected at the edge of the gas-oil contact would form a continuous barrier between the oil and gas zones, andwater would advance uniformly downdip without segregation due to gravity effects provided a specified, minimum water-injection rate was maintained.
The model test results also indicated that it was not necessary to fill the gas cap completely with water.
Water injection at the edge of one of the gas caps was initiated in March, 1958, to field test gas-cap water injection. Water breakthrough occurred at a downstructure producing well in April, 1959, after approximately 2.5 million bbl of water had been injected into the gas cap. This was the volume calculated to be required to form the barrier between the oil zone and gas cap. This performance indicates that prevention of oil encroachment into dry gas caps in a peripheral water flood by water injection at the gas-oil contact appears practical and that the model studies provided a valid prediction of field performance.

Introduction
The Sholem Alechem Fault Block "A" Sims Sand Unit was one of the first major waterflood projects in Oklahoma to utilize a peripheral injection pattern. Design of control measures to minimize oil encroachment into the large crestal gas caps was one of the greatest single problems during engineering planning of this flood. Engineering studies indicated that saturation of the gas caps with oil displaced by the peripheral water flood could result in a loss of about 27 million bbl of oil, or over one-half the estimated waterflood recovery. This estimate was based on a residual oil saturation after water flooding of 35 per cent pore volume, compared to the negligible oil saturation initially in the gas caps.
Interference Between Oil Fields
Authors: Hurst William 
Published: February 2020

Published in Petroleum Transactions, AIME, Volume 219, 1960, pages 175–192.

Abstract
What is entailed here is the extension of the simplified material balance formulas to encompass interference between oil fields. As previously reported, the explicitness as so revealed for the cumulative pressure drop as a function of all factors contributing to its change in the material balance equation, is now transcribed through the inter-communicating aquifer to effect an increased pressure drop on an adjoining field by interference. Such is performed by mathematical analyses and the application of the Laplace transformations.
What is accomplished is that the reiteration problems previously associated with interference studies are nullified, since volumetric changes for the fluids in situ are automatically adjusted by the explicitness so expressed, and what pertains to the superposition principle applies only to the impeded water drive upon a subject field, which Is likewise incorporated in the over-all pressure drop that results.
The mathematics treats with the rigorous solution of the problem, as well as with methods easily amenable to numerical interpretation by the practicing engineer. In all cases, however, what is deduced for areal extents, reveal interference between wells when time becomes large that further substantiate the analyses.
Probably of equal significance, all variables and formation characteristics are accounted for. This applies to the differences in PVT analyses that occur from field to field and the physical parameters associated with the lithology of the reservoirs. The latter is deduced from a rigorous interpretation of the unsteady-state flow problem for sands of different permeabilities in series. Thus, what purports to be a trial-and-error calculation to include variations in sand conditions within the intercommunicating aquifer to define water drive has little importance compared to the designation of such parameters at the reservoir to constitute the essential criteria.

Introduction
In a recent publication, the reader has been introduced to the simplified material balance formulas. It has been shown that the complexities formerly associated for identifying and determining reservoir pressure in the material balance relationship can be resolved by treating with the Laplace transformations, the inversion of which reveals pressure as an explicit function of all factors contributing to its change.
Liquid-Density Correlation of Hydrocarbon Systems
Authors: Madrazo Aurelio 
Published: February 2020

Published in Petroleum Transactions, AIME, Volume 219, 1960, pages 386–389.

Abstract
The Standing-Katz method for predicting liquid densities of reservoir fluids has been tested using experimental data of 154 bottom-hole or recombined reservoir fluid samples. New pressure- and temperature-correction curves for the Standing-Katz type correction are presented which improve the accuracy of prediction.

Introduction
The present study was undertaken to investigate the known methods of determining liquid densities and to select one of them which might yield a better correlation if additional data were employed. An appropriate correlation would incorporate the following characteristics:ease of handling in the computations,results within engineering accuracy anddata easily accessible.
After careful investigation of the different methods, the Standing-Katz correlation appeared to have these characteristics. The Standing-Katz correlation for liquid densities of hydrocarbon systems is based upon limited data. The original work, which employs apparent densities for methane and ethane, was based on data of 15 saturated crude oils in equilibrium with natural gas. Therefore, if test of the correlation using additional experimental data would serve either to validate the Standing-Katz correlation or to form a basis for corrections if such were necessary.

Procedure and Graphical Solution
The data of 154 bottom-hole or recombined reservoir fluid samples were employed to calculate the densities at 14.7 psia and 60 degrees F by the method described in Table 1. Volume contributions for methane and ethane were assigned from the pseudo liquid density plot (Fig. 1), but volume contributions for N2, CO2 and H2S were not considered. The densities computed at reference conditions of 14.7 psia and 60 degrees F were then elevated to their respective temperatures and pressures by the use of the correction curves proposed by Standing. The percentage differences between the experimental values and the calculated values were determined: these samples were grouped into temperature, pressure and density ranges to determine a possible trend. It appeared that, at temperatures above 160 degrees F, the calculated density values were consistently larger than the experimental density values; however, no obvious trend was found for the density and pressure ranges.

Abstract
Background: The occurrence of perioperative heart failure will affect the quality of medical services and threaten the safety of patients. It is of great significance to improve the quality of medical service and ensure the safety of patients with perioperative heart failure by scientific method. Methods: Firstly, the data of preoperative patients are preprocessed, and the patient data is divided into the structural data of numerical data and the unstructured data of textual data. The numerical data of the patient is constructed by the gradient boosting tree model, and the textual features of the patients are extracted by the topic model of the text-based data. Fusion of textual features and numerical features, and finally through a simple logistic regression to predict the patient critical illness. Results: To evaluate the performance of the proposed method, we made preoperative prediction of critical events of heart failure in perioperative period based on the real operative data of patients from a hospital, and the results showed that the sensitivity and specificity of the model proposed could reach 94% and 97%, thus verifying the feasibility and effectiveness of the model. Conclusions: a novel method of predicting preoperative critical disease is proposed for the properties of medical heterogeneity data in perioperative patients. This work is the first study that integrates the numerical laboratory data and textual diagnostic data of patient for extracting the predictive feature by XGBOOST and LDA model respectively, and builds a low cost, scalable and effective model of predicting preoperative critical disease by using logistic regression. The experimental demonstrate show that it is better to predict whether the patients have heart failure with Numerical and Textual Attributes of patients
