Hospital Access Patterns of Children With Technology Dependence
Authors: Moynihan Katie , França Urbano L. , Casavant David W. , Graham Robert J. , McManus Michael L. 
Published: March 2023

OBJECTIVES
We studied hospital utilization patterns among children with technology dependence (CTD). We hypothesized that increasing pediatric healthcare concentration requires those caring for CTD to selectively navigate healthcare systems and travel greater distances for care.

METHODS
Using 2017 all-encounter datasets from 6 US states, we identified CTD visits defined by presence of a tracheostomy, gastrostomy, or intraventricular shunt. We calculated pediatric Hospital Capability Indices for hospitals and mapped distances between patient residence, nearest hospital, and encounter facility.

RESULTS
Thirty-five percent of hospitals never saw CTD. Of 37 108 CTD encounters within the remaining 543 hospitals, most emergency visits (70.0%) and inpatient admissions (85.3%) occurred within 34 (6.3%) high capability centers. Only 11.7% of visits were to the closest facility, as CTD traveled almost 4 times further to receive care. When CTD bypassed nearer facilities, they were 10 times more likely to travel to high-capability centers (95% confidence interval: 9.43–10.8), but even those accessing low-capability facilities bypassed less capable, geographically closer hospitals. Transfer was more likely in nearest and low-capability facility encounters. CTD with Medicaid insurance, Black race, or from lower socioeconomic communities had lower odds of encounters at high-capability centers and of bypassing a closer institution than those with white race, private insurance, or from advantaged communities.

CONCLUSIONS
Children with technology dependence routinely bypass closer hospitals to access care in facilities with higher pediatric capability. This access behavior leaves many hospitals unfamiliar with CTD, which results in greater travel but less transfers and may be influenced by sociodemographic factors.
Patterns of seismic activity after three great earthquakes in the light of Reid's elastic rebound theory
Authors: Howell B. F. 
Published: March 2023

AbstractReid's elastic rebound theory implies that regional stress should increase in the interval between characteristic earthquakes. Based on this, it is postulated that the size of the largest annual earthquakes should also increase in this interval. To test this, the variability of seismic activity in the New Madrid, Missouri, and the San Francisco and Fort Tejon, California, regions is examined using sequences of magnitudes of largest annual earthquakes. The calculated probability of a magnitude 6.5 or 7.5 earthquake based on past occurrences varies significantly with time. It is currently growing in the New Madrid and San Francisco areas and declining in the Fort Tejon area. The calculated probability frequently increases in the five years before earthquakes 1.5 magnitudes or more greater than the regional average maximum annual magnitude. The center of significant activity is moving northeastward in the New Madrid area.
Seismic ground-motion hazard mapping incorporating site effects for Los Angeles, Orange, and Ventura counties, California: A geographical information system application

Published: March 2023

AbstractThe seismic ground motion hazard with site conditions incorporated is mapped for a 10% probability of exceedance in 50 years for the three counties affected by the 1994 Northridge earthquake (Mw 6.7). The source model of Petersen et al. (1996) was used to calculate peak horizontal acceleration (pga) and 5% damped spectral acceleration (SA) levels at 0.3- and 1-sec periods for alluvium, soft-rock, and hard-rock site conditions. A geologic map that differentiates the three site conditions was produced using shear-wave velocity maps of Tinsley and Fumal (1985) and extended into other areas that were not mapped by Tinsley and Fumal using 1:250,000 scale geologic maps. Ground-motion maps for each site condition were overlaid with the geologic map to produce the resulting hazard maps. The effect of geology on the hazard is observed only slightly in the peak ground acceleration map, more in the 0.3-sec SA map, and significantly more in the 1-sec SA map. The uncertainties for ground motions represented on these three maps ranges from 0.1 to 0.3 g for pga and 0.2 to 1.0 for SA; in general, 95% confidence limits are about ±50% of the mean ground-motion value.
Propagation characteristics of short-periodSnandLgin the Middle East
Authors: Rodgers Arthur J. , Ni James F. , Hearn Thomas M. 
Published: March 2023

AbstractWe present propagation characteristics of the short-period regional seismic phases Sn and Lg for the Middle East. Digital waveform data from the Iranian Long Period Array (ILPA) and the Global Seismic Network (GSN) stations ABKT (Alibek, Turkmenistan), ANTO (Ankara, Turkey), KEG (Kottamya, Egypt), and KIV (Kislovodsk, Georgia) were used in this study. Three-component rotated seismograms were bandpass filtered (0.5 to 5.0 Hz) and examined for the presence and strength (amplitude) of Sn and Lg relative to the Pn and Pg phases. The short-period Sn and Lg waveforms show great variability. Sn propagates efficiently for paths crossing the Mediterranean, Black, and Caspian Seas as well as for paths passing north of the Greater Caucasus, Alborz, and Kopet-Dag Mountains. Generally, Sn is not observed or propagates inefficiently for paths with segments beneath the Turkish plateau and northern Iranian plateau, consistent with a previous study by Kadinsky-Cade et al. (1981). This study finds that the zone of inefficient Sn propagation coincides with a zone of low Pn velocities (&lt;7.9 km/sec) determined by Hearn and Ni (1994) from Pn tomography. Lg is consistently not observed for paths crossing the Mediterranean, Black, and Caspian Seas. Lg propagates efficiently for paths crossing the northern Arabian shield. Generally, Lg propagates efficiently for paths contained within the Turkish-Iranian plateau. Paths in the Middle East greater than about 2000 km consistently show no or little Lg energy.The correspondence of zones of inefficient Sn propagation and low Pn velocities suggests that high temperatures and partial melt lie at shallow depths in the upper mantle beneath the Turkish plateau and northern Iranian plateau. The presence of water, presumably due to subduction of hydrated oceanic crust, lowers the solidus temperature and enhances partial melt. Lg is blocked by oceanic crustal structures as well as by structural and topographic variations associated with tectonic boundaries.
Estrategias de formación de carteras rentables en empresas de energía renovables
Authors: Miralles-Quirós José Luis , Miralles-Quirós María del Mar 
Published: March 2023

Las energías renovables han aumentado su importancia en los últimos años debido al daño que causan los combustibles fósiles al medio ambiente. Por ello, las empresas de energías renovables parecen ser oportunidades de inversión rentables, dado que es probable que obtengan importantes beneficios en el futuro. Sin embargo, las evidencias empíricas hasta la fecha no siempre han coincidido en esta probable rentabilidad. Además, las metodologías empleadas en la literatura empírica existente son complicadas y no son viables para la mayoría de los inversores. Por lo tanto, se propone un enfoque que combina el uso de medidas de performance, reglas de selección o cribado, rendimientos estandarizados y estrategias de cartera, que puede ser fácilmente aplicado por los inversores. Este enfoque da lugar a altos rendimientos acumulados de más del 200% y otros ratios positivos, incluso cuando se tienen en cuenta los costes de transacción. Esto debería animar a los inversores a invertir en estas energías renovables y contribuir a mejorar el medio ambiente.Las energías renovables han aumentado su importancia en los últimos años debido al daño que causan los combustibles fósiles al medio ambiente.

Inversión socialmente responsable: aspectos económicos y psicológicos en la gestión de fondos de inversión
Authors: Boumda Djampou Beatrice Carole 
Published: March 2023

Los datos proporcionados por organismos tanto nacionales como internacionales revelan el interés creciente que los inversores particulares manifiestan hacia los fondos de inversiones sostenibles y responsables (ISR). Si bien desean rentabilidades positivas, dichos inversores esperan de esos fondos una inversión en activos que cumplen criterios ambientales, sociales y de gobierno corporativo (ASG). Estos criterios imponen una clara limitación en las estrategias que los gestores de fondos ISR pueden aplicar. ¿El doble objetivo financiero y ético implica un comportamiento diferencial de los gestores de fondos ISR? El propósito principal de este artículo es proporcionar una visión económica y psicológica de los ISR. Analizaremos desde la revisión bibliográfica si existen diferencias de rentabilidad entre fondos convencionales y fondos ISR e investigaremos la relación entre rentabilidad y flujo de dinero y la existencia del efecto disposición en ISR, con el fin de ofrecer a los gestores y a los inversores una visión global para sus tomas de decisiones financieras.

El presente trabajo tiene como objetivo analizar si la incorporación de una estrategia que incluye criterios ES G en la elaboración de una cartera de inversión, en combinación con los cinco factores propuestos por Fama y French (2015), tiene un impacto significativo en el rendimiento de dicha cartera. Para ello, se ha utilizado un universo de datos corporativos europeos para el periodo de enero de 2008 a diciembre de 2021. Los resultados obtenidos demuestran que el hecho de que los inversores incorporen criterios ES G, a la hora de seleccionar las empresas que conforman sus carteras, tiene un efecto neutro sobre los resultados de éstas.

IMPLEMENTATION OF AN EXCLUSIVE BREASTFEEDING POLICY IN WONOGIRI REGENCY
Authors: Pratiwi Dewi Nur , Ernawaty  
Published: March 2023

Introduction: Breastfeeding is the best intake to fulfill nutrition of babies aged 0-6 months. In Wonogiri Regency, exclusive breastfeeding achievement in 2017 is 53.62% and 25 out of 34 public health centers haven’t reached the target yet. Method: This research was descriptive research type with observational approach and cross-sectional design. Sample was 34 public health centers in Wonogiri Regency, with nutritionist, midwives and health cadres from each public health centers as respondents. The data were collected using interview and questionnaire techniques, and correlation analysis performed using the contingent coefficient method. Result: show that communication factors showed good result for respondent’s knowledge, consistency in obtaining socialization and transmission to carry out further socialization. Resource factors show that availability of nutrition staff isn’t sufficient and funds lack for activities related to exclusive breastfeeding. On disposition factors, respondents disagree with the gift provided from the formula milk distributor because it can inhibit achievement of exclusive breastfeeding purpose. And many public health centers still don’t have exclusive breastfeeding SOP. Conclusion: It can be concluded that training, availability of facilities and infrastructures in lactation room and number of staff positively affect target achievement of exclusive breastfeeding. The effort that can be done is by giving counselling of breastfeeding to workers and healthcare staff, fulfillment of facilities and infrastructure of lactation room to support exclusive breastfeeding, making SOP related to breastfeeding for public health centers.
Turbidity, pH, Direct Gram as Predictors of Symptomatic Urinary Tract Infections in Pregnant Women
Authors: Hattah Dhian Karina Aprilani , Sjahril Rizalinda , Sriwijaya Sriwijaya 
Published: March 2023

Introduction: Urinary tract infections (UTIs) are common in the community, including among pregnant women. This study investigates turbidity, urine pH, and direct gram as predictors of symptomatic urinary tract infection in pregnant women. Methods: A total of 177 pregnant women with suspected UTIs based on clinical and laboratories at the community health center in Makassar were collected from September to December 2021. The Urine sample was assessed for turbidity, urine pH, direct gram, and urine culture. Results: Urine turbidity was found in 108 (75.5%) patients who had positive cultures and PPV of 94.7%. The mean pH of the urine from UTI patients was 6.42 and without UTIs was 6.45. Urine that grows Gram-positive bacteria showed the most alkaline pH (mean pH=6.71) and was significantly less acidic than urine with UTI negative. In contrast, urine with Gram-negative bacteria had the most acidic pH (mean PH=6.30). The gram direct test shows a significant association with UTIs. Conclusions: Turbid urine can predict urinary tract infections in pregnant women that provide clinical symptoms. In addition, leukocytes esterase test further selected the samples. Urine pH showed no significant correlation with UTI. Less acidic urine pH is particularly associated with Gram-positive bacterial infections. Furthermore, direct gram can predict the event of UTI.
Development of Unique, Non-Damaging, Non-Crosslinked Solids Cleanout Fluid System with Enhanced Solids Suspension Capacity
Authors: Busteed John E. , Fragachan Francisco E. 
Published: March 2023

Abstract
Traditional, natural polymer-based fluid systems, used for wellbore cleanout applications have several characteristic limitations related to temperature degradation, solids transport capacity, energized applications foam stability and are always a source or risk if circulation is interrupted, due to lack of static suspension capability. The objective was to create a synthetic polymer-based fluid system which has enhanced properties when compared to the natural polymer based linear gels traditionally employed in wellbore cleaning.
The characteristics of the novel fluid system were investigated through a series of experiments including rheology and suspension testing vs. polymer concentration and with various types, sizes and grades of proppant in both foamed and non-foamed conditions. Fluid performance was subsequently validated via multiple field trials at depths from 800m to 3,000m.
The unique system has significantly enhanced suspension and carrying capacity resulting in reduced cleanup times, material consumption and cost. The new system mitigates any requirement for "viscosified pill" sweeps. The system can be energized and when doing so creates foams which are stable at surface and at BHT (bottom hole temperature). The energized systems remain stable even when created with a very low foam quality and have inherent friction reduction properties. The ECD (equivalent circulation density) across potential loss zones can be readily controlled by adjusting the foam quality and thereby preventing any potential formation damage associated with fluid lost to formation. Furthermore, the fluid is non-crosslinked and non-damaging. The polymer utilized in this novel system is a fast-hydrating polymer which can be mixed "on the fly" or batch mixed. All the above translate to increased wellbore cleaning efficiency.
This unique and innovative non-crosslinked low viscosity system is characterized by its ability to suspend solids even under static conditions at raised temperatures. Typical cleanout linear gels require a minimum rate be maintained to prevent solids fallback and have limited carrying capacity. This novel system greatly reduces such rate and has a greatly increased solids carrying capacity.
Agile Approach to Mitigate Corrosion and Scaling Issues in Unconventional Vaca Muerta Wells

Published: March 2023

AbstractDuring well-work to install artificial lift in unconventional horizontal wells in El Trapial field, scale and corrosion were identified in two different pads. The West pad had been on production for fifth teen (15) months prior the intervention while the East pad had nine (9) months online. An interesting observation during the inspection of the carbon steel tubulars was that most of the corrosion was located on the lower section of the string but chrome (Cr) 1% chemical injection mandrels were not affected. Based on the samples analyzed, the corrosion was associated to high carbon dioxide (CO2) partial pressure and acidized water production while the scale samples confirmed it was barium sulfate (BaSO4). Both conditions are detrimental to the well integrity and productivity, highly impacting the operating cost to resolve them. As the full field development is the next phase under factory execution design, it was critical to rapidly incorporate these learnings and generate an effective mitigation plan.Applying a traditional project management approach would have delivered a working solution but probably not on time and with low tolerance to unanticipated changes. Agile framework is an alternative methodology that initially started in the software development industry and centers around four values: 1) Individuals and interactions over processes and tools 2) Working software over comprehensive documentation 3) Customer collaboration over contract negotiation 4) Responding to change over following a plan. These values promote a mindset that enables transparency within the team and stakeholders, prioritizing value adding work, adaptability, frequent integration of feedback, self-organizing teams, and continuous improvement of the product. Based on recent successful applications of this approach in other projects, the multidisciplinary team decided to work in an Agile framework to accelerate the solution for the upcoming development well’s design.Following adapted Scrum ceremonies, within 5 Sprints of 2 weeks each, the team simulated fluid velocities in different tubing sizes, corrosion rates varying tubing size and metallurgy, modeled drawdown strategies, and assessed materials lead time and incremental costs. Ultimately, the team generated effective short- and long-term solutions despite unexpected deviations along the process: replicate successful drawdown management of appraisal wells to control high initial pressures, change tubular metallurgy from carbon steel to chrome alloy, transition from initial tubing flow to casing flow while well natural capacity allows it, install artificial lift with 2 3/8" tubulars and inject solid scale inhibitors during the initial hydraulic fracturing stimulation of the wells.This paper will cover how the methodology of the Agile process was applied, the technical work generated and final recommendation of this alternative approach to manage a project.
