Published: April 2021

Se analizó de forma perceptual la transferencia de conocimiento en tecnología de la madera en instituciones educativas estatales de Costa Rica. Se realizaron capacitaciones activo-pasivas en temas de secado, preservado y calidad de la madera, llevando a cabo tres evaluaciones de aprendizaje (precurso, postcurso y 30 semanas luego del postcurso). Con estas se valuó la percepción, conocimiento adquirido y limitaciones de los sistemas empleados. Se obtuvo una gran similitud entre las temáticas de secado y preservado con conocimientos previos superiores al 65 %, aprendizajes del 85 % y retenciones de conocimiento del 75 %; caso contrario se evidenció con la temática de calidad, la cual presentó un conocimiento previo del 20 %, aprendizaje del 83.5 % y retención del 75.6 %; los temas de secado y preservado mostraron la mejor percepción, considerados como simples, aplicables, útiles y entendibles; mientras que el tema de calidad se consideró complicado, complejo, inaplicable pero útil. Finalmente, se encontró que el aprendizaje de secado y preservado debe ser una combinación de 50 %-50 % entre teoría-práctica; mientras la calidad debería ser 25 %-75 % teoría-práctica.

Published: April 2021

OBJECTIVES:
To increase the number of essential consult elements (ECEs) included in initial inpatient consultation requests between pediatric residents and fellows through implementation of a novel consult communication tool.

METHODS:
Literature review and previous needs assessment of pediatric residents and fellows were used to identify 4 specific ECEs. From February to June 2018, fellows audited verbal consult requests at a medium-sized, quaternary care children’s hospital to determine the baseline percentage of ECE components within consults. A novel consult communication tool containing all ECEs was then developed by using a modified situation-background-assessment-recommendation (SBAR) format. The SBAR tool was implemented over 3 plan-do-study-act cycles. Adherence to SBAR, inclusion of ECEs, and consult question clarity were tracked via audits of consult requests. A pre- and postintervention survey of residents and fellows was used to examine perceived miscommunication and patient care errors and overall satisfaction.

RESULTS:
The median percentage of consults containing ≥3 ECEs increased from 50% preintervention to 100% postintervention with consult question clarity increasing from 52% to 92% (P &lt; .001). Overall perception of consult miscommunication frequency decreased (52% vs 18%; P &lt; .01), although there was no significant change in resident- or fellow-reported patient errors. SBAR maintained residents’ already high consult satisfaction (96% vs 92%; P = .39) and increased fellows’ consult satisfaction (51% vs 91%; P &lt; .001).

CONCLUSIONS:
Implementation of a standardized consult communication tool resulted in increased inclusion of ECEs. Use of the tool led to greater consult question clarity, decreased perceived miscommunication, and improved overall consult satisfaction.
A vasanyagcsere szabályozása, hepcidinexpresszió fiziológiás és pathológiás körülmények között
Authors: Egyed Miklós 
Published: April 2021

Összefoglaló. A humán szervezetnek az alapvető biokémiai reakcióihoz
vasra és annak biztonságos használatára van szükség. Emberben vasexcretios út
hiányában a vasanyagcsere sarkalatos pontja a duodenális absorptio, amelyet a
májsejtek által termelt hormon, a hepcidin szabályoz. A hepcidin a ferroportin
lisosomalis degradációját okozva blokkolja a vasnak a vérbe való belépését a
duodenális enterocytából, a reticuloendothelialis rendszer (RES) macrophagokból
és a májsejtekből. A reguláló hormon képzését a szervezet vaskészlete mellett az
erythropoiesis, hypoxia és inflammatorikus folyamatok befolyásolják. A
szabályozás kóros eltérései vashiány vagy vasterhelés útján súlyos betegségeket
okozhatnak. A hepcidin képződését befolyásoló folyamatokat illetően ismereteink
jelentősen gyarapodtak, közleményünk célja ezek bemutatása.
Summary. The basic biochemical reactions of the human body require
iron and its safe utilisation. In absence of an iron-excreation pathway in
human, the pivotal point of iron metabolism is duodenal absorption, which is
regulated by a hormone produced by liver cells, the hepcidin. Causing lisosomal
degradation of ferroportin, hepcidin blocks the iron entry into the blood from
duodenal enterocytes, reticuloendothelial system (RES) macrophages, and liver
cells. In addition to the body’s iron stores, the production of the regulatory
hormone is also affected by erythropoiesis, hypoxia and inflammatory processes.
Abnormal regulation can lead to serious illness through iron deficiency or iron
stress. Regarding the processes influencing the formation of hepcidin, our
knowledge has significantly increased and the aim of our paper is to present
them.
Floral development of the myrmecophytic Acacia cornigera (Leguminosae)
Authors: Gómez-Acevedo Sandra Luz 
Published: April 2021

Background: The Neotropical ant-acacias show morphological variations in their vegetative characteristics as a consequence of their relationship with ants. However, there is no information regarding whether floral organs have also undergone any modification that prevents resident ants from approaching the inflorescences in anthesis.
Questions: Are the patterns of floral development affected by the relationship with ants? Is there any floral organ or structure involved in avoiding the presence of ants during the flowering period? At what stage of development do these modifications arise, if at all?
Studied species: Acacia cornigera (L.) Willd.
Study site: Santiago Pinotepa Nacional, Oaxaca and Los Tuxtlas, Veracruz. March and May 2015.
Methods: Dissections of inflorescences in every developmental stage from two populations, were examined using scanning electron microscopy.
Results: The inception patterns of the calyx (irregular), corolla (simultaneous), androecium (acropetally in alternate sectors) and gynoecium (precocious) agree with previous reports for non-myrmecophyic species of the Acacia genus. In mature stages, the presence of stomata is characteristic of bracts and petals.
Conclusions: Floral development is not affected by ant-acacia interactions; however, the occurrence of stomata on bracts and petals could be an important feature indicative of secretory structures to resolve the conflict of interest between ants and pollinators during the flowering period. In this sense, a new approach based on histological analyzes will be necessary in flowers of A . cornigera .
Investigations on Surface Behavior of Electro-Less Nickel Phosphorus Coatings with Nano Additives on Magnesium Alloy Used In Automotive Applications
Authors: Et. al. Motilal Lakavat , 
Published: April 2021

To enhance the damage and corrosion behaviour for alloys, the coating is found because of the maximum fitted technique. Mg-based alloys have a good range of business application. These alloys show a high specific strength but bad attire and corrosion resistance. A standard coating of Cu, Ni & Zn etc. provides a physical barrier against the wear and tear rate and corrosion attack of magnesium substrate. In the recent study, plating Ni-P was thru going on AZ91 composite by immersing samples into Nickel sulphate bath in the existence of surfactants. The study of the mechanism of Ni-P deposits was studied utilizing SEM. Ni-P coating was coated consistently within the existence of surfactants. Result of surfactant and Result of Nano-additives ZnO, Al2O3 and SiO with various quantities were examined. 0.5 g/l Nano Al2O3 additive-enhanced the deposition of Ni-P on AZ91 magnesium composite and hereafter the similar consequences are detected just in case of SiO accumulation. Effect of ZnO was also noticed. So is extremely clear that Ni-P coating is extremely effective to scale back the corrosion and rise the wear and tear behaviour if it's used together with Nano additive and therefore the surfactants.

Ten Urgent Priorities Based on Lessons Learned From More Than a Half Million Known COVID-19 Cases in US Prisons
Authors: Barnert Elizabeth , Kwan Ada , Williams Brie 
Published: April 2021

COVID-19 is ravaging US prisons. Prison residents and staff must be prioritized for vaccination, but a rapidly mutating virus and high rates of continued spread require an urgent, coordinated public health response. Based on knowledge accumulated from the pandemic thus far, we have identified 10 pressing public health priorities for responding to COVID-19 in prisons: (1) accelerate population reduction coupled with community reentry support, (2) improve prison ventilation systems, (3) ensure appropriate mask use, (4) limit transfers between facilities, (5) strengthen partnerships between public health departments and prison leadership, (6) introduce or maintain effective occupational health programs, (7) ensure access to advance care planning processes for incarcerated patients and delineation of patient health care rights, (8) strengthen partnerships between prison leadership and incarcerated people, (9) provide emergency mental health support for prison residents and staff, and (10) commit to public accountability and transparency. Dedicated prison leaders cannot accomplish these public health priorities alone. We must mobilize prison leaders, staff, and residents; public health departments; community advocates; and policymakers to work together to address the pandemic’s outsized impact in US prisons.
Medicaid Expansions and Participation in Supplemental Security Income by Noncitizens
Authors: Muchomba Felix M. , Kaushal Neeraj 
Published: April 2021

Objectives. To estimate the effect of Medicaid expansion on noncitizens’ and citizens’ participation in the Supplemental Security Income (SSI) program. The Affordable Care Act (ACA) expanded Medicaid eligibility to cover low-income nonelderly adults without children, thus delinking their Medicaid participation from participation in the SSI program. Methods. Using data from the Social Security Administration for 2009 through 2018 (n = 1020 state-year observations) and the Current Population Survey for 2009 through 2019 (n = 78 776 respondents), we employed a difference-in-differences approach comparing SSI participation rates in US states that adopted Medicaid expansion with participation rates in nonexpansion states before and after ACA implementation. Results. Medicaid expansion reduced the SSI (disability) participation of nonelderly noncitizens by 12% and of nonelderly citizens by 2%. Estimates remained robust with administrative and survey data. Conclusions. Medicaid expansion caused a substantially larger decline in the SSI participation of noncitizens, who face more restrictive SSI eligibility criteria, than of citizens. Our estimates suggest an annual savings of $619 million in the federal SSI cost because of the decline in SSI participation among noncitizens and citizens.
Maximum entropy-based forest fire likelihood mapping: analysing the trends, distribution, and drivers of forest fires in Sikkim Himalaya.
Authors: Banerjee Polash 
Published: April 2021

Abstract
The recent episodes of forest fires in Brazil and Australia of 2019 are tragic reminders of the hazards of forest fire. Globally incidents of forest fire events are on the rise due to human encroachment into the wilderness and climate change. Sikkim with a forest cover of more than 47%, suffers seasonal instances of frequent forest fire during the dry winter months. To address this issue, a GIS-aided and MaxEnt machine learning-based forest fire prediction map has been prepared using a forest fire inventory database and maps of environmental features. The study indicates that amongst the environmental features, climatic conditions and proximity to roads are the major determinants of forest fires. Model validation criteria like ROC curve, correlation coefficient, and Cohen’s Kappa show a good predictive ability (AUC = 0.95, COR = 0.81, κ = 0.78). The outcomes of this study in the form of a forest fire prediction map can aid the stakeholders of the forest in taking informed mitigation measures.

Published: April 2021

Abstract
Purpose: Streptomyces are familiar with biocontrol activity and producing a broad range of biologically active substances. Our goal was to isolate a local Streptomyces bacteria that can promote plant growth via siderophore, indole acetic acid (IAA) production and phosphate solubilization and biocontrol the phytopathogens to reduce the heavy usage of chemical fertilizers and fungicides.Methods: The designated strains were isolated from local soil samples in Saudi Arabia via the standard serial dilution method, identified morphologically, by scanning electron microscope (SEM) and 16S rDNA sequencing and screened against many soils borne fungi. Siderophore, IAA production and phosphate solubilization were detected and measured.Results: A strain designated Streptomyces tricolor strain HM10 was isolated and showed aerial hyphae in SEM. Selected isolate showed highly homolog revealed to 99.69 % with the type strain Streptomyces tricolor LMG 20328. In vitro experiments showed a growth inhibition of ten phytopathogenes by strain HM10 fermentation broth and production of plant growth promoting compounds such as siderophore, IAA and solubilize phosphate. S. tricolor strain HM10 exhibited high antagonism effect against tested fungi (i.e. Colletotrichum gloeosporides with inhibition zone exceed 18 mm whereas the lowest effect was against Alternaria solani (8 mm)). Furthermore, the highest siderophore production was recorded to strain HM8 followed by strain HM10 with 64 and 22.56 h/c (halo zone area/colony area). With regard to IAA production, Streptomyces strain HM10 was the highest producer with value 273.02 µg/ml.Conclusion: Streptomyces tricolor HM10 is an important biological agent that can be used to promote plant growth and control of phytopathogen.

Dynamic Molding Deposition: The additive manufacturing in partially ordered system
Authors: Marquette Christophe , Courtial Edwin-Joffrey , Colly Arthur 
Published: April 2021

Abstract
Additive manufacturing (AM) is now identified as a powerful bundle of fabrication techniques. Limitations were identified to be mostly related to the availability of reformulated materials compatible with existing AM technologies. What if we were able to dynamically generate sacrificial molds with unlimited architectures and material composition? We have discovered such a process, called Dynamic Molding Deposition (DMD) in partially ordered powder system and demonstrated its capacity to produce highly complex objects with 100 µm resolution, without any building plate or support structures. The DMD compatible materials were shown to be almost infinite, from low to high viscosity, from thermoplastic to elastomers. Our process enables us to build unexpected composite objects made up of injection material and powder grains from the dynamic mold. This feature opens the path to a complete new field of research and applications.

Published: April 2021

Abstract
Several new settlements have been constructed in the desert areas of Egypt. These new settlements are composed of many new types of problematic formations that creating many geological and engineering challenges. One of the most problematic formations is weak sandstones that are characterized by low mechanical strength and bearing capacity as well as high deformability and fracturing. The physico-mechanical characteristics of these sandstones are the most crucial parameters in design and stability evaluation of any surface and underground engineering structures. The determination of these parameters is complicated, difficult and time consuming as well as is required a great accuracy in sample preparation and testing procedure, and is considered as expensive testing. The objective of this study is analyzing the shallow marine weak sandstones to determine the best and significant correlations of petrographic characteristics and physical engineering index properties that may be useful for estimating unconfined compressive strength (UCS), uniaxial pore volume compressibility (mv), compressional P-wave velocity (Vp) and dynamic constrained modulus (Es). As well as predicting the UCS and mv from compressional P-wave velocity test and estimating the petrographic parameters from the physical engineering index parameters. The present study revealed that the studied samples are high to very high porous sandstones with very low to moderate density, and classified as extremely weak to weak rocks with very high deformability and very low wave velocity. In this study, the physical properties form non-significant linear relations with UCS, Vp, and Es as well as there are moderately strong to strong correlations between P-wave velocity, constrained modulus, unconfined compressive strength and compressibility characteristics. Based on the regression analysis, the dolomite cement and matrix contents, quartz and rock fragments contents, packing density and proximity, sorting, roundness, mean grain size, and grain to cement contact exhibited weak to strong statistical correlations with mechanical properties of the studied sandstones. These relationships revealed that due to the mineralogical, textural, and microstructure variations of the studied recycle origin sandstones, the non-significant to significant relations are resulted. In this study, the backward multiple regression was applied to predict the UCS, mv, Vp and Es of the studied sandstones by selecting some physical and petrographic characteristics which exhibit statistically significant correlations with them. The results of this study were presented in the form of predictive models and equations.
