ABSTRACT
Different types of sediment-hosted whole-rock Pb isotope (206Pb/204Pb, 207Pb/204Pb, 208Pb/204Pb) compositions were determined from phyllites, carbonaceous phyllites (&gt;1% TOC), and meta-litharenites belonging to the Serra do Garrote Formation, which is part of the Proterozoic Vazante Group, Brazil. Results were integrated with lithogeochemistry in order to identify the Pb isotopic signature of Zn enrichment (up to 0.24 wt.% Zn) associated with meta-siliciclastic-hosted sulfide mineralization that formed prior to the Brasiliano Orogeny (850 to 550 Ma) in order to (1) understand the nature of siliciclastic sediment sources, (2) identify possible metal sources in pre-orogenic meta-siliciclastic-hosted Zn mineralization, and (3) evaluate the genetic links between the Zn enrichment in the relatively reduced phyllite package, and different styles of syn-orogenic Zn ± Pb mineralization (hypogene Zn-silicate and Zn-Pb sulfide) in overlying dolomitic carbonates throughout the Vazante-Paracatu Zn District, Brazil.
The whole-rock 206Pb/204Pb and 207Pb/204Pb isotope ratios of meta-siliciclastic rocks plot as positively sloping, sub-parallel arrays with radiogenic, upper continental crust compositions, which could represent a detrital contribution from at least two upper continental crust sources. However, the 206Pb/204Pb versus207Pb/204Pb isotope system does not distinguish between Zn-enriched samples and un-mineralized samples. In the whole-rock 206Pb/204Pb–208Pb/204Pb plot, Zn-enriched samples form a flat trend of lower 208Pb/204Pb values (38.3 to 39.5) compared to the Zn-poor ones that follow common upper crustal trends. Zinc-enriched samples have low whole-rock Th/U values (&lt;4) and higher whole-rock U concentrations compared to unmineralized samples. These support the hypothesis that U (± Pb) was added by pre-orogenic metalliferous fluids, which were in turn derived from underlying Paleoproterozoic and Archean basement rocks. Due to U addition, the original whole-rock thorogenic and uranogenic Pb isotope systems were decoupled in mineralized samples. Pre-orogenic metalliferous fluids have similar present-day first-order characteristics, including: (1) relatively high U/Pb and (2) low Th/U values, when compared to galena in the major carbonate-hosted Zn ± Pb deposits (Vazante, Morro Agudo, Ambrosia, Fagundes) in the Vazante Group. These results support the hypothesis that Zn-rich layers and veins in mineralized carbonaceous phyllites could be linked to the same origins as carbonate-hosted mineral deposits throughout the Vazante Basin, but further data are warranted. We suggest that the tectonic evolution of the Vazante Basin saw multiple phases of Zn-rich mineralization over protracted time periods from around 1200 to 550 Ma.

Abstract
Here we provide the most comprehensive determinations of the rest-frame UV luminosity function (LF) available to date with the Hubble Space Telescope (HST) at z ∼ 2–9. Essentially all of the noncluster extragalactic legacy fields are utilized, including the Hubble Ultra Deep Field, the Hubble Frontier Fields parallel fields, and all five CANDELS fields, for a total survey area of 1136 arcmin2. Our determinations include galaxies at z ∼ 2–3 leveraging the deep HDUV, UVUDF, and ERS WFC3/UVIS observations available over an ∼150 arcmin2 area in the GOODS-North and GOODS-South regions. All together, our collective samples include >24,000 sources, >2.3× larger than previous selections with HST. We identify 5766, 6332, 7240, 3449, 1066, 601, 246, and 33 sources at z ∼ 2, 3, 4, 5, 6, 7, 8, and 9, respectively. Combining our results with an earlier z ∼ 10 LF determination by Oesch et al., we quantify the evolution of the UV LF. Our results indicate that there is (1) a smooth flattening of the faint-end slope α from α ∼ −2.4 at z ∼ 10 to α ∼ −1.5 at z ∼ 2, (2) minimal evolution in the characteristic luminosity M* at z ≥ 2.5, and (3) a monotonic increase in the normalization

from z ∼ 10 to 2, which can be well described by a simple second-order polynomial, consistent with an “accelerated” evolution scenario. We find that each of these trends (from z ∼ 10 to 2.5 at least) can be readily explained on the basis of the evolution of the halo mass function and a simple constant star formation efficiency model.
Anisotropic Turbulence in Position–Position–Velocity Space: Probing Three-dimensional Magnetic Fields
Authors: Hu Yue , Lazarian A. , Xu Siyao 
Published: July 2021

Abstract
Direct measurements of three-dimensional magnetic fields in the interstellar medium are not achievable. However, the anisotropic nature of magnetohydrodynamic (MHD) turbulence provides a novel way of tracing the magnetic fields. Guided by the advanced understanding of turbulence’s anisotropy in the position–position–velocity (PPV) space, we extend the structure-function analysis to measure both the three-dimensional magnetic field orientation and Alfvén Mach number M
A, which provides the information on magnetic field strength. Following the theoretical framework developed in Kandel et al., we find that the anisotropy in a given velocity channel is affected by the inclination angle between the three-dimensional magnetic field direction and the line of sight as well as media magnetization. We analyze the synthetic PPV cubes generated by incompressible and compressible MHD simulations. We confirm that the PPV channel’s intensity fluctuations measured in various position angles reveal plane-of-the-sky magnetic field orientation. We show that by varying the channel width, the anisotropies of the intensity fluctuations in PPV space can be used to simultaneously estimate both magnetic field inclination angle and strength of total magnetic fields.
Nurse Practitioner Student Perceptions of a Pilot Simulated Gerontologic Telehealth Visit
Authors: LaManna Jacqueline B. , Eckhoff Dawn O. , Duncan Jodi , Anderson Mindi 
Published: July 2021

Background:
Recently published nurse practitioner (NP) education organization recommendations and telehealth equipment acquisition necessitated integration of telehealth simulation into NP curricula at a large, public university. The COVID-19 pandemic and associated rapid uptake of telehealth accelerated the need for evidence-supported research in tele-health simulation in NP education.

Method:
A formative gerontologic simulation scenario using telehealth robot technology was developed by synthesizing best practice guidelines for simulation and telehealth delivery. The simulated telehealth visit used standardized patients and embedded participants. Primary care NP students' perceptions of simulation effectiveness, situational realism, and telehealth robot usability were evaluated using three quantitative tools.

Results:
Thirty-three primary care Doctor of Nursing Practice students participated in this gerontologic telehealth simulation. Students found the simulation to be effective and realistic, and found the telehealth robot technology to be usable.

Conclusion:

NP students positively evaluated this telehealth simulation experience. Additional research is needed on evidence-based teaching strategies to guide faculty in teaching and evaluating telehealth content.

Published: July 2021

OBJECTIVES:
We aimed to compare the demographic and clinical characteristics between pediatric cardiac arrest patients treated in Gaziantep at South-eastern Anatolian region and Izmir at Aegean Shore.

MATERIALS And METHODS:
We retrospectively reviewed sociodemographic characteristics, laboratory parameters, and clinical outcomes of pediatric patients that underwent cardiopulmonary resuscitation due to prehospital cardiac arrest at two pediatric emergency departments in Izmir Hospital of Health Sciences University and Gaziantep Cengiz Gökçek Kadın Doğum ve Çocuk Hospital of Health Ministry between August 2017 and August 2018.

RESULTS:
The present study included 188 patients (112 patients from Gaziantep and 76 patients from Izmir). All patients arrived at the hospital through emergency medical services. The median age was lower (14 days vs. 15 months; P < 0.001), and the proportion of Syrian refugees was higher in patients from Gaziantep (78.6% vs. 7.9%; P < 0,001). In both centers, respiratory failure was the most common etiology. In patients from Gaziantep, pH levels were lower (median: 7.10 vs. 7.24), and lactate levels were higher (median: 6 mmol/L vs. 3.6 mmol/L; P < 0.001). The mortality rate was higher among patients from Gaziantep (27.7% vs. 7.9%; P = 0.001).

CONCLUSIONS:
The rate of Syrian refugees among children who were brought to emergency department due to pre-hospital cardiac arrest was much higher in Gaziantep compared to Izmir. Syrian children were significantly younger and had more severe tissue hypoxia, resulting in a higher mortality rate.

MULHER E RELIGIÃO
Authors: Santos José Augusto Rodrigues dos 
Published: July 2021

Através da história, a religião tem sido uma força catalisadora para muitas das transformações mais marcantes em todas as sociedades. Como elemento de aculturação, a religião serviu como muleta psicológica e emocional para os espantos e medos que o homem experimentou pela sua incapacidade em entender as transformações do seu envolvimento. O divino emergiu com naturalidade na forma como o homem procurou entender o mundo. A mulher, raramente entrou no encontro do humano com a sua transcendência. Através dos tempos, o papel da mulher foi secundarizado, seja pelas suas particularidades biológicas, seja pelos papeis sociais que lhe estavam cometidos. Para essa segregação social da mulher a religião deu expressivo contributo. Hoje, a luta da mulher ainda passa, em algumas sociedades, pela assunção dos seus direitos fundamentais sonegados pelas regras morais intrínsecas a algumas religiões.

Abstract
Throughout history, religion has been a catalyst for many of the most striking transformations in all societies. As an element of acculturation, religion served as a psychological and emotional crutch for the astonishment and fears that human kind suffered due to his inability to understand the changes in his involvement. The divine emerged naturally in the way man understood the world. The woman rarely entered the human encounter with his transcendence. Throughout the ages, the role of women has become secondary, either because of their biological particularities or because of the social roles that were committed to them. Religion has made a significant contribution to this social segregation of women. Today, the struggle of women still involves, in some societies, the assumption of their fundamental rights withheld by the moral rules intrinsic to some religions.

Published: July 2021

Water deficit is considered the most critical environmental factor for peanut production in Brazil, as it constitutes one of the major constraints to the expansion of its cultivation in the suitable crop zones of the country. Determining crop water demand is fundamental to increasing yield with lower water consumption. The present study aimed to evaluate the effects of full and deficit irrigation levels (L1 = 8%, L2 = 27%, L3 = 63%, L4 = 94% and L5 = 100% replenishment of crop evapotranspiration) on the development, growth and yield of peanut crop sown in two times, February and March. Treatments were distributed in a split-plot randomized complete block design, with four replicates, using a line-source sprinkler system. Irrigation depths from 65 to 314 mm were applied with the levels L1 to L5 during the first and second cropping cycles. Full irrigation with sowing in March was more advantageous due to yield increase of up to 30% compared to sowing in February, but crop cycle was 25 days longer. Water stress caused by deficit irrigation reduced plant height, seed mass and pod yield, while full irrigation (L5) led to yields from 4,141 to 5,102 kg ha-1 for February and March, approximately three times higher than those obtained with the lowest irrigation level (L1).
Highlights

Peanut has great importance in the food and industry of several countries.
The results of this research apply to regions that require irrigation, which is of about 70% of the areas of the globe with this legume.
This paper contributes with information that emphasizes the possibility of cultivation in the drought season, aiming at the expansion of the crop and the production of quality seeds using irrigation.

Published: July 2021

The present work shows the effects of the different agricultural wheels traffic on the soil physical properties on a Typic Argiudoll soil worked under no-tillage cropping system. Soil compaction produced by traffic was quantified through these parameters: a) cone index, b) rut depth and c) soil water content at the traffic moment. Grain chaser, sprayer, harvester combine and tractor equipped with commonly used wheels in the study area were tested. The main results obtained showed that the tyres with the highest inflation pressure and tyre ground pressures produced the highest values of cone index and rut depth. Typic Argiudoll soil worked under continuous no-tillage cropping system is not able to constrain topsoil and subsoil compaction when it is wheeled by tyre with ground pressures greater than 77.6 kPa.
Highlights

Soil compaction causes a reduction in root growth and yield in many crops.
Soil under a no-tillage system does not limit topsoil and subsoil compaction when wheeled by tyres with ground pressures greater than 77.6 kPa
When the machinery load increases on soils with high bearing capacity (soils under a long-term no-tillage system), the subsoil compaction problems increase.
Waste assessment in distribution and marketing logistics of horticultural products: evidence from Brazil
Authors: Mendonça Lima Dag , Ramos de Oliveira Andréa Leda 
Published: July 2021

Worldwide, one-third of the food produced is inconsumable due to marketable quality losses. Parallelly, and given the growing world population, levels of waste have become unacceptable. Supply channels play a fundamental role in establishing strategies for food waste mitigation. The objective of this research was to analyze if good operational practices with different dimensions of distribution and commercialization logistics may contribute to reduce fruit and vegetable waste. The studied dimensions were: logistics, operations, technology, trade and management. Several questionnaires were administered to 83 specialized wholesale merchants from a large supply center in Brazil, for lettuce, potato, orange, papaya and tomato. The results indicated that for papaya and potato, low and high waste generation are associated with a greater number of anti-waste actions (p = 0.0071 and p = 0.0469 respectively). For tomato, lettuce and orange, no significant differences for found. These results represent a first approach to understanding the reasons for food waste at wholesale centers.
Highlights:

Worldwide, one-third of the food produced is inconsumable due to marketable quality losses. In Brazil, about 40 thousand tons of food is wasted per year.
Food waste in the fruit and vegetable supply chain is associated with the following dimensions: logistics, operation, technology, trade and management.
For papaya and potatoes, low levels of residues are associated with a greater number of anti-waste actions such use of a cold chamber and use of promotional pricing, respectively.
For tomato, lettuce and orange, no significant differences was found for high and low levels of waste in relation to the number of actions undertaken in these chains.
