Caminhos da curadoria e o pós-museu
Authors: Brolhani Joanna
Published: June 2021

Na obra Museums and the Interpretation of Visual Culture (2000), Eilean-Hooper-Greenhill discute a cultura da imagem na pedagogia museal, contrastando o modelo do museu modernista com o que ela chama de pós-museu. O presente ensaio busca discutir esse conceito, assim como o conceito de constelação pós-colonial de Okwui Enwezor, para desvelar gestos curatoriais a partir de uma situação específica observada em 2019 no Museu Oscar Niemeyer: um espaço de entressalas que abriga obras de três diferentes instituições (MON, MAC-PR e Bienal de Curitiba), provocando um diálogo sobre fronteiras, compromissos e desafios da prática curatorial e narrativas institucionais. Abstract In the work Museums and the Interpretation of Visual Culture (2000), Eilean Hooper-Greenhill discusses image culture in museum pedagogy, from the modernist museum in contrast to what she calls the post-museum. The present essay aims to discuss this concept, as well as the concept of post-colonial constellation, by Okwui Enwezor, to unfold curatorial gestures from a specific situation observed in 2019 at Oscar Niemeyer Museum: a space among exhibition rooms that hosts three different institutions (MON, MAC-PR and Bienal de Curitiba) and provokes a dialog on borders, commitments and challenges of curatorial practices and institutional narratives.

A série de esculturas Germinares surge no contexto da pandemia do Corona Vírus que determinou a situação de isolamento social. Toda minha investigação escultórica evoca o feminino em sua simbiose com a natureza, traduzido em formas orgânicas, em elementos de volume e vazio, em equilíbrios e desequilíbrios. Aqui, o retorno à origem... A forma, que antes se expandia no espaço, timidamente, e com requinte, apenas ousa germinar, ou quem sabe, retorna para seu interior mais íntimo.Palavras chave AbstractThe Germination sculpture series appears in the context of the Corona Virus Virus pandemic that determined the situation of social isolation. All my sculptural research evokes the feminine in its symbiosis with nature, translated into organic forms, into elements of volume and emptiness, into balances and imbalances.

Debido a la pandemia generada por el COVID-19, países de todo el mundo entraron en cuarentena total, modificando la cotidianidad de las personas drásticamente, una de las poblaciones más afectadas por los cambios son los niños, muchos de ellos con diversidad funcional y trastornos del desarrollo debieron parar sus procesos terapéuticos, es así como el articulo hace un intento en ahondar por los efectos de la cuarentena en dicha población infantil, así mismo, establecer los impactos generados por la virtualidad que ofrecen las sesiones terapéuticas desde esta modalidad. Es por ello que, a través del diseño de un cuestionario dividido en dos momentos, se logró concluir que dentro de los efectos colaterales del covid-19 por la cuarentena, se vieron afectadas en los niños las áreas emocionales, de comportamiento y el sueño, así mismo, el inicio de sesiones virtuales logró impactar de forma positiva, aportando no solo al objetivo propio de cada proceso de intervención sino también a la salud mental de la dinámica familiar.
Movimientos sociales ambientales en América Latina: otros escenarios para los estudios en Comunicación
Authors: Espinel-Rubio Gladys Adriana , Estévez-Lizarazo Jaqueline , Albán-Gallo Eduardo
Published: June 2021

Este artículo identificó los repertorios de confrontación, que desde la comunicación y los medios tradicionales y/o alternativos, han sido objeto de estudio en las investigaciones sobre los movimientos sociales ambientales (MSA) en Colombia, Argentina, Ecuador y Bolivia entre el 2000-2017. Es una investigación cualitativa, documental que utiliza el enfoque bibliográfico. Para ella se identificaron los marcos teóricos y metodológicos, y las temáticas abordadas, especialmente, las vinculadas con Comunicación Social como campo de estudio o disciplina. Se pudo determinar que, aunque existe un corpus relacionado con los MSA en Latinoamérica, especialmente para México y Brasil, los estudios son abordados desde la otras Ciencias Sociales y Humanas; lo comunicativo o lo mediático se toca tangencialmente. Se determinó que frente irrupción y posicionamiento de los movimientos sociales ambientales en el continente, inspirados no solo en la protección de la Madre Tierra o de los territorios cargados de sentidos y cosmogonías, sino por el inminente cambio climático, sumado al posicionamiento de apuestas del pensamiento como el Buen Vivir, es imperativo para las escuelas de comunicación latinoamericanas abrirse a nuevas preguntas sobre las prácticas comunicativas, tácticas y/o estrategias insertas en los repertorios de confrontación de los MSA.

Authors: Contreras-Colmenares Adrián Filiberto , Jiménez-Villamarín Imelda
Published: June 2021

Desde décadas, las Tecnologías de la información y la comunicación (TIC) se conciben como herramientas favorecedoras de los procesos de enseñanza y aprendizaje.  El ser humano con su uso tiene la posibilidad de aprender y relacionarse. Sin embargo, se hacen evidentes las dificultades de los educandos de primaria en las competencias comunicativas, que les impiden avanzar en los procesos de lectura y escritura. Por ello, el propósito del estudio fue identificar el efecto del uso de los recursos tecnológicos en el desarrollo de competencias de lectura y escritura en ambientes de aprendizaje. La metodología seleccionada para realizar el estudio fue la cualitativa bajo investigación-acción con apoyo del paradigma socio-crítico. Se tomaron 18 participantes de un contexto rural en la Escuela Vijagual. Entre otras, se llegó a la siguiente conclusión: Las tareas de lectura y escritura realizadas con uso de TIC fortalecen la interacción entre usuario-máquina y motivan al estudiante a realizar procesos de lectura y escritura de manera activa, participativa; en sus escritos, se evidenció mayor riqueza textual en cuanto a coherencia, sentido y significado.

Authors: Sürmelioğlu Nursel , Demirkan Kutay , Karakoç Emre , Gündüz Murat , Özcengiz Dilek
Published: June 2021

Purpose: This study aimed to identify drug-related problems at treatment
in patients with sepsis and septic shock and to evaluate the
contribution of the clinical pharmacist. Methods: This study was
conducted at intensive care units(ICU) of a university hospital. A study
group in which the clinical pharmacist participated in the treatment
management of septic patients and a control group in which the clinic
did not have a pharmacist was formed. In the treatment of the control
group, interventions were made for drug-related problems detected by the
clinical pharmacist. Study and control group were compared in terms of
length of ICU stay, time to initiation of appropriate antimicrobial
drug(s), appropriateness of antimicrobial dosing, and drug treatment
costs. Results: Total of 65 patients were included in the study group
prospectively in which the intervention of clinical pharmacist provided
for the drug treatments and retrospectively 65 patients in the control
group without any intervention. In the study group, 670 recommendations
were made for 753 problems related to their drug therapy. Between
groups, improvement in appropriateness of antimicrobials in terms of
dose, time to initiation of appropriate antimicrobial therapy, daily
antibiotic costs in all patients and antibiotic costs in patients with
impaired renal function statistically significant difference were found.
Conclusions: As a result of clinical pharmacist involvement in sepsis
management, it has been shown to contribute to the prevention and
management of drug interactions, to start antimicrobial therapies more
quickly, to select the appropriate drug and dose, especially
antimicrobials, and to save the costs of antimicrobial drugs.
Interventions to Enhance Medication Safety in Residential Aged Care Settings: An Umbrella Review
Authors: Alruthea Shadi , Bowman Paula , Tariq Amina , Hinchcliff Reece
Published: June 2021

Aim: To conduct the first systematic synthesis of existing evidence
reviews on interventions to enhance medication safety in RACS, to
establish and compare their effectiveness. Method: This umbrella review
included examination of meta-analyses, scoping and systematic reviews.
Four electronic databases (MEDLINE, EMBASE, CINAHL, and The Cochrane
library database of Systematic Reviews) were explored for eligible
reviews. Those meeting the inclusion criteria were critically appraised
using the JBI Critical Appraisal Instrument for Systematic reviews and
Research Syntheses by two authors. Results: Fourteen reviews covering
166 unique, primary studies were included. Interventions were grouped
according to type: medication review (n= 12); staff education (n= 8);
multidisciplinary team meetings (n= 6); computerised clinical decision
support systems (n= 5); and transferring medicines information between
health care settings (n= 1). Most reviews showed mixed evidence to
support interventions’ effectiveness, due to the significant
heterogeneity between original research studies in respect to sites,
samples sizes and intervention periods. However, in all intervention
categories, pharmacists’ collaboration with other health care
professionals was most beneficial, showing definitive evidence for
improving medication safety and quality of prescribing in RACS. The
evidence suggests that combining two or more interventions is the most
promising approach, despite this presenting implementation barriers in
the resource-limited environments of many RACS, and methodological
challenges in identifying the precise contribution of individual
interventions, when implemented concurrently. Conclusion: Health
stakeholders should explore a combination of at least two interventions,
such as medication review and staff education, to improve medication
safety in RACS.
Fluorescent guided lymph node harvest in laparoscopic Wilms nephroureterectomy - a new technique
Authors: Pachl Maximilian
Published: June 2021

Lymph node harvest is an integral part of Wilms tumor surgery with both
SIOP and COG protocols asking for more than 6 lymph nodes to best
evaluate for nodal spread and a subsequent need for intensification of
treatment. The majority of studies show that in both open and minimally
invasive resections the median number of nodes removed is 4. Indocyanine
green and near infrared fluorescence may be the key to solving this
problem. In adult gynaecology, colorectal and breast cancers, ICG is
used to identify sentinel nodes and facilitate nodal harvest. This
report describes its use in Wilms tumor
Trends of lymph node sampling and metastasis in pediatric patients with clear cell, epithelioid, and synovial sarcomas
Authors: Weller Jennine , Westermann Carly , Patel Palak , Beckman Ross , Pratilas Christine , Morris Carol , Rhee Daniel
Published: June 2021

Background: Clear cell sarcoma (CCS), epithelioid sarcoma, and synovial
sarcoma are rare tumors historically identified as high risk for lymph
node metastasis. Nodal metastasis in adults with these subtypes has been
described. This study investigates incident nodal metastasis and
associated survival in children with these subtypes. Procedure: Using
the National Cancer Database (2004-2015), we created a retrospective
cohort of 1303 patients (aged ≤25 years) who underwent local control
therapy for CCS, epithelioid sarcoma, and synovial sarcoma. Kaplan-Meier
curves estimated overall survival (OS) by subtype. Stratifying on
subtype, Cox regressions assessed OS by lymph node sampling status and
nodal metastasis. Results: There were 103 (7.9%) patients with CCS, 221
(17.0%) with epithelioid sarcoma, and 979 (75.1%) with synovial
sarcoma. Lymph node sampling was more frequent in patients with CCS
(56.3%) and epithelioid sarcoma (52.5%) versus synovial sarcoma
(20.5%, p<0.001). Synovial sarcoma metastasized to lymph
nodes less frequently than CCS or epithelioid sarcoma (2.2% vs. 14.6%
and 15.0%, p<0.001). Across all subtypes, lymph node
metastasis was associated with inferior OS (HR 2.10, CI 1.44-3.07,
p<0.001). Lymph node sampling was associated with improved OS
in CCS (HR 0.35, CI 0.15-0.78, p=0.010), inferior OS in synovial sarcoma
(HR 1.60, CI 1.13- 2.25, p=0.007), and no statistical association with
OS in epithelioid sarcoma. Conclusions: Lymph node metastasis is rare in
children with synovial sarcoma. Lymph node sampling procedures were not
consistently performed for patients with CCS or epithelioid sarcoma, but
improved OS supports routine lymph node sampling in children with CCS.

Published: June 2021

Introduction: The implementation of interdisciplinary care strategies
for the follow-up of patients with asthma has proven to be very
effective in improving the long-term evolution of these children.
Objectives: Describe the clinical, functional and therapeutic
characteristics of patients with a diagnosis of uncontrolled severe
asthma (UCSA), identify the differences in the characteristics in the
management between patients with difficult-to-treat severe asthma (SDCA)
and treatment-resistant severe asthma (STRA Materials: Analytical study
of serial cases, patients were evaluated for 6 months, patients with
UCSA diagnosis were admitted to the Pneumonology Service of the
Pediatric Hospital of Córdoba, with ages between 5 and 15 years old.
Results: 23 patients entered the study. 47.82% were defined as SDCA and
52.17% STRA. During the first 6 months of the program; hospitalizations
were only 4% (p: 0.001). Besides, the number of visits to the emergency
room decreased to 39.13% (p: 0.003). Regarding the Inhalation
technique, 73.9% (n: 17) presented improvement (p: 0.0001). Only 13%
(n = 3) of the patients continued with ACT <20 (p: 0.0001). We
found differences in the use of rescue medication (p: 0.003) and greater
attendance at Emergency Rooms (p: 0.005), during the 6-month evaluation
process, in favor of the group of treatment-resistant asthmatics
Conclusion: Implementing this type of interdisciplinary program allowed
a marked improvement in all modifiable variables of asthma in patients
with SDCA. All this not only leads to improving the management of
patients with UCSA.
Spatial heterogeneity of soil properties and solute transport characteristics and their correlations in degraded wetland soils
Authors: Zhang Yinghu , Zhang Jinchi , Zhang Zhenming , Zhang Mingxiang
Published: June 2021

Soil properties have a significant influence on solutes redistribution
in the soil vadose zones. The aim of this study was to assess the
relevance of soil properties for solute transport characteristics in
degraded wetland soils using 72 undisturbed soil columns from two
experimental fields located in Robinia pseudoacacia (CH) and Tamarix
chinensis (CL) communities. Combining soil column tracer experiments,
all experiments were conducted under the same initial and boundary
conditions using Brilliant Blue FCF as a conservative tracer. Solute
transport characteristics were described by four measures of dye
solution steady infiltration rate of effluents, dye solution
concentration of effluents, soil column dye staining patterns, and
cumulative dye solution leaching. Numerical modeling by the
dual-permeability model in HYDRUS-1D was used to simulate the proportion
of cumulative dye solution leaching from soil macropore flow. This study
showed that basic soil properties exhibited a significant difference at
CH site and at CL site. Dye solution steady infiltration rate of
effluents at CH site decreased with soil depth, but increased at first
and then decreased with soil depth at CL site. Dye solution
concentration of effluents both at CH site and at CL site decreased
nonlinearly with soil depth. Soil column dye staining patterns were
significantly different among different soil locations, indicating the
largest dark blue staining domains from soil depth of 0-10 cm at CH site
and 20-40 cm at CL site. The proportion of cumulative dye solution
leaching from soil macropore flow was from 37.6 to 61.1% at CH site,
whereas from 0 to 99.9% at CL site. Basic soil properties played
inconsistent roles in solute transport characteristics. The
understanding of soil properties and its correlation with solute
transport characteristics is the first step for degraded wetland
restoration and development. Some alternative solutions of wetland
restoration are proposed for managers.

Background: Although changes of the main lymphocyte subsets (T cells, T
helper, T cytotoxic, B cells, NK cells) and lymhocyte activation status
in COVID-19 patients have been reported, the results of the studies
differ each other. Therefore, we aimed to determine lymphocyte subgroups
and activation status of them with flow cytometry at the time of
diagnosis in COVID-19 patients and examine the relation of them with
disease stage and length of hospital stay. Methods: Fourty patients
included in the study were compared with the age and sex matched 40
healthy controls. COVID-19 patients were divided into 2 groups as mild
and severe stage disease. Flow cytometry assay was performed to examine
the numbers of lymphocyte subsets and activation status of them. Total
lymphocyte count was calculated and CD45, CD3, CD4, CD8, CD19, CD27,
CD38, CD56, CD57, IgD were studied on lymphocyte gate. T helper / T
cytotoxic rates and length of hospital stay were recorded. Results: The
patients’ CD3(+)CD4(+) ( T helper) count and CD27 expression on T cells
counts were significantly lower, and CD57 expression on CD3(+)CD8(+) T
cytotoxic cells were significantly higher (p<0.05) than
control gruop. When the patients were divided into mild and severe
stages, it was observed that CD38 expression on T cells were
significantly lower in severe stage patients (p< 0.05) Total
lymphocyte count and CD3(+) T lymphocyte count were negatively
correlated with the lengt of hospital stay as statistically significant
(p <0.05). Conclusion: Our data showed that the SARS-CoV-2
primarly effects on T lymphocytes. It was thought that this effect
occured by impairment of development and activation of T lymphocytes.
There are some discordances among the studies on T lympocytes in the
literature. Studies with more patients are needed to make this
information more reliable.

Published: June 2021

Aim: To evaluate the tendency, knowledge, awareness and behavior
patterns of urology residents training at different institutions in
Turkey about the use of fluoroscopy in operations. Methods: The
13-questioned survey prepared using “Google Forms©” as of 01.03.2021
was shared for four weeks in the “WhatsApp®” application group, which
includes 279 urology residents studying with university hospitals and
training and research hospitals in Turkey. One hundred and thirteen
participants, who completed the questionnaire were included in the
study. Results: Of the 113 urology residents included in the study, 56
(49.6%) were studying in university hospitals and 57 (50.4%) were in
training and research hospitals. 67.3% of the residents stated that
they never hesitated to participate in the operations which fluoroscopy
was used. Additionally, the residents stated that, also 43.4% of the
auxiliary healthcare staff frequently refrain from being involved in
these cases(p <0.001). While 21 (37.5%) of the residents
trained in the university hospital reported that they hesitated from
these cases, this rate was found that 16 (28.2%) of the residents who
were trained in the training and research hospitals and a significant
difference was observed between two groups (p <0.016). Among
residents, the rate of using radioprotective lead apron was 94.7%, and
the rate of thyroid shield use was 98.2%. While the rate of using
radiation protective glasses was 1.8%, it was learned that none of the
residents used radioprotective gloves. Only 5.3% of the residents
stated that they are trained in subjects about the harmful radiation
effect. Conclusion: Urology residents in Turkey do not receive
sufficient training on the harmful effects of fluoroscopy, which they
frequently use in their daily practice. In addition, the residents whom
training in university hospitals are more scared of the radiation
exposure from fluoroscopy than their colleagues working in training and
research hospitals.
Improving pain management in an hospital ward by implementing an educational intervention: A prospective cohort study
Authors: sasson maayan ben , Hagalili Ofir , Schiff Elad , Attias Samuel , Vulfsons Simon
Published: June 2021

Introduction: the Pain management in internal medicine ward is a common
problem. Studies have shown that the evaluation of pain and its
documentation by the medical staff is inaccurate and tends to
underestimate the level of pain reported by patients. In addition,
Physicians often report lack of knowledge and misconceptions regarding
pain management. Objectives: To assess the impact of a structured pain
educational program on knowledge, skills and abilities [KSA’s] of
internal medicine ward physicians in pain management. Methods: Eleven
physicians from Internal medicine ward B at Bnai-Zion Medical Center, a
tertiary academic center in Israel, participated in a pain educational
program. Questioners regarding pain KSA’s, were completed before and
after the educational intervention. Concomitantly, a pain management
protocol was implemented in the department. Results: There was a 55.5%
(P.value = 0.003) improvement in the overall satisfaction of the
physicians regarding pain management in the internal ward on a 1 to 6
Likert scale (1-strongly disagree, 6-strongly agree) .In a modified
KnowPain50 [KP50] questionnaire that assesses physicians KSA, the
average score for all physicians improved by 15.3% (P.value = 0.012)
after the intervention. Conclusion: A targeted educational intervention
on pain management can improve physician’s KSA, and this we belive may
lead to a better treatment for patients suffering from pain in the
hospital scenerio.
Leveraging genetic data to investigate the effects of interleukin-6 receptor signalling on levels of 40 circulating cytokines.
Authors: Rahman Rezbieara , McEwan Lauren , Ryan David , Gill Dipender
Published: June 2021

Abstract Interleukin 6 (IL-6) is a circulating cytokine that is
implicated in a range of inflammatory diseases. However, the broad
effects of IL-6 receptor (IL-6R) signalling on other circulating
cytokines is not known. Using summary-level data from genome-wide
association studies, we leveraged genetic variants that proxy IL-6R
signalling in two-sample Mendelian randomization analyses to investigate
effects on levels of 40 circulating cytokines. Increased genetically
proxied IL-6R signalling was associated with reduced levels of 10
circulating interleukins, chemokines, and growth factors. The findings
from this study support feedback effects of IL-6R signalling on reducing
levels of a range of circulating cytokines and identify compensatory
mechanisms that may be modulating its inflammatory effects. These
results provide novel insight into the mechanisms by which IL-6R
signalling may be contributing to inflammatory and autoimmune diseases.
Global solution to Cauchy problem of fractional drift diffusion system with power-law nonlinearity
Authors: Gu Caihong , Tang Yanbin
Published: June 2021

In this paper we consider the global existence, regularizing-decay rate
and asymptotic behavior of mild solutions to the Cauchy problem of
fractional drift diffusion system with power-law nonlinearity. Using the
properties of fractional heat semigroup and the classical estimates of
fractional heat kernel, we first prove the global-in-time existence and
uniqueness of the mild solutions in the frame of mixed time-space Besov
space with multi-linear continuous mappings. Then we show the asymptotic
behavior and regularizing-decay rate estimates of the solution to
equations with power-law nonlinearity by the method of multi-linear
operator and the classical Hardy-Littlewood-Sobolev inequality.

Authors: Bethke Maria , Varga Georg , Weinhage Toni , Sabharwal Harshana , Mellgren Karin , Randau Gerrit , Rolfing Meike , Wittkowski Helmut , Foell Dirk , Michgehl Ulf , Burkhardt Birgit
Published: June 2021

Background Mature aggressive B-cell lymphoma are heterogenous
malignancies that make up more than half of all diagnosed Non-Hodgkin
lymphoma in children and adolescents. The overall survival rate
increased over the last decades to 80–90%, due to fine tuning of
polychemotherapy. However, new therapeutic implications are needed to
further increase the overall survival. Current clinical trials analyze
the therapeutic effect of rituximab in pediatric patients, while the
mechanism of action in vivo is still not fully understood. Methods
Effector molecules important for tumor defense were analyzed before and
at day five after rituximab treatment via flow cytometry. Serum
rituximab levels were measured with an ELISA. Results We evaluated
patient parameters that may affect treatment response in relation to
rituximab administration and serum rituximab levels. We indeed found a
reduction of FcγRII levels after rituximab treatment in monocyte
subtypes, while FcγRI expression was significantly increased, pointing
to exhaustion of FcγRII mediated B cell depletion and compensation via
FcγRI mediated trogocytosis. Serum levels of proinflammatory marker
proteins S100A8/A9 and S100A12 significantly decreased after treatment
to normal levels from an overall proinflammatory state before treatment.
CD57, perforin and granzyme B expression decreased after treatment,
probably due to exhaustion of NK cells. Conclusion The highlighted
effects of rituximab treatment on patient’s immune response help
understanding the biology behind tumor defense mechanisms and effector
function. After subsequent studies, these novel insights might be
translated into patient care and could contribute to improve treatment
of pediatric patients with mature aggressive B-cell lymphoma.

Effect of Interest Rate on Stock Prices in Ghana
Authors: Arhenful Peter , Yeboah Augustine Kwadwo , Adjei Kofi Sarfo
Published: June 2021

The paper assesses the effect of interest rate on stock prices, with emphases on Ghana Stock Exchange; using monthly time series data from July 2007 to December 2019. The Augmented Dickey-Fuller (ADF) test was employed to establish the stationarity properties of the data or otherwise. Using the Ordinary Least Squares (OLS) estimation technique of Multiple Regression, the results (? = – 0.891, p < 0.05) revealed an indirect association between interest rates and stock prices in the Ghanaian context; which is consistent with the theoretical conclusion that an increase in interest rate results in a decrease in stock prices. Thus, in the light of this finding, it was recommended that policymakers should consider the stock market dynamics due to the significant relationship that exists between the two macroeconomic variables.
Unlocking the Challenging Pathways of Youth Participation in Ghana’s Youth Employment and Entrepreneurial Development Agency
Authors: Brenya Edward , Arthur Dominic Degraft , Nyarko Janet
Published: June 2021

Youth participation in public policies such as the employment policy process has gained prominence in academic and policy literature. Despite this, research on youth participation in the employment policy process has received little attention in Ghana. This paper draws on documentary analysis to unlock the challenging pathways of youth participation in Ghana’s youth employment and entrepreneurial development agency. The paper finds that a web of challenges such as insufficient access to information, over-politicization of GYEEDA, poor level of coordination of stakeholders, and prevalence of diversity and social exclusion are embedded in obstructing the youth participation in GYEEDA. The study recommends that policymakers such as the government and other stakeholders should provide adequate measures to ensure that beneficiaries such as the youths are engaged in the design, formulation, and execution of the youth employment policy process in Ghana.
Timing of pair formation and male acquisition of alternate plumage by three wintering dabbling ducks
Authors: Titman Rodger , Titman Elise , Craik Shawn
Published: June 2021

Pair formation in ducks is thought to be influenced by the acquisition of breeding plumage, the occurrence of courtship display, or both. We examined the frequency of pair formation in Mallard (Anas platyrhynchos), Green-winged Teal (Anas crecca carolinensis), and Northern Shoveler (Spatula clypeata) in the central valley of California in relation to the frequencies of male attainment of breeding plumage and courtship display. Predictions related to two hypotheses are: (1) the timing of pair formation is directly related to the attainment of breeding (definitive alternate) plumage by males, and (2) frequencies of courtship display are highest during pair formation. Most female Mallard were paired by the end of October, with >80% in pairs by early December. Of Northern Shoveler, 90% were paired by early January and 90% of female Green-winged Teal were paired by early February. The highest rates of courtship display by Mallard were observed during October through November, by Northern Shoveler in November, and by Green-winged Teal in November through January. Courtship display was, therefore, relatively frequent at the same time as pair formation for all three species. Northern Shoveler spent less time in courtship display than the other two species. Most (90%) male Mallard had acquired alternate plumage by mid-November, Northern Shoveler by early February, and Green-winged Teal by mid-December. Thus, timing of pair formation coincided with timing of attainment of breeding plumage in Mallard and Green-winged Teal but not Northern Shoveler.

The inventory of lichens, allied fungi, and their parasites in the Ottawa region has grown from 391 in 1988 to 543 today, almost entirely because of the discovery of species overlooked in previous years and the inclusion of fungal parasites. In addition, almost 140 names have changed with reclassifications and re-identifications. These changes are presented here together with a list of synonyms updating the 1988 list. Vouchers are cited for all new records, and notes are presented for many species neither described nor keyed out in easily accessible literature. Reference is made to the new, complete list of lichens and lichenicolous fungi available online. The new checklist includes one species new for North America (Tremella christiansenii); five species and one variety new for Canada (Caloplaca parvula, Caloplaca reptans, Cladonia petrophila, Enchylium tenax var. ceranoides, Leprocaulon adhaerens, and Merismatium peregrinum); four new for Ontario (Caloplaca reptans, Kiliasia tristis, Lempholemma chalazanum, and Rinodina fimbriata); and nine new for Quebec (Arthonia helvola, Arthonia hypobela, Caloplaca parvula, Cladonia petrophila, Lempholemma chalazanum, Leprocaulon adhaerens, Merismatium peregrinum, Rimularia badioatra, and Tremella christiansenii). Although the climate of the region is warming, especially with higher minimum temperatures in winter, the lichen biota has not increased as a result but, in fact, may be threatened by the effects of climate change on the health of the forests and the trees that support lichens. Air quality has improved in recent decades, allowing numerous lichens to again become established in urban areas. Local areas of especially rich lichen diversity can be found on both the Ontario and Quebec sides of the region, and some of these “hot-spots” are mentioned. Other factors influencing the decrease or increase of lichen cover are also discussed.

Background/Aim. Surgical stress itself, as well as hypothermia induced by general anesthesia and low ambient temperature, activates stress hormone response with changes in catecholamines and counter-regulatory hormones. The aim of this study was to investigate the acute hormone stress response in patients who underwent major surgical procedures and the efficiency of external and internal warming methods in alleviating these changes. Methods. The study included a total of 60 patients who underwent major open abdominal surgical procedures and were randomly divided into 4 groups: control non-warmed (C), externally warmed using forced-air warming mattress (W), internally warmed using intravenous amino acids (A), and warmed with a combination of external and internal method (A+W). Esophageal temperature was used as a measure of core temperature. Concentrations of epinephrine, norepinephrine, cortisol, prolactin, and testosterone were measured. Blood samples for hormone measurement were obtained at two time points for catecholamines ? 90 min before and 120 min after finishing the surgery, and at additional two-time points for cortisol, prolactin, and testosterone (24 and 48 hrs after surgery). Results. In the W and A+W groups, the temperatures did not significantly differ between time points but constantly decreased in the C and A groups, with a statistically significant difference between the anesthesia induction and the 120th min (35.61 ? 042 vs. 33.86 ? 0.71?C; p < 0.000 and 35.81 ? 0.54 vs. 34.45 ? 0.41?C; p < 0.000, respectively). Catecholamine concentrations in all groups showed a significant increase during surgery, with the highest values recorded in the non-warmed group (777.07 ? 800.08 after vs. 106.13 ? 89.63 pg/mL before surgery for epinephrine and 1,349.67 ? 984.16 vs. 580.53 ? 465.38 for norepinephrine, p < 0.000). Concentrations of cortisol and prolactin also showed a significant increase at the same time point, with a tendency to normalize after 48 hrs. On the contrary, testosterone concentrations showed a decrease after 120 min without normalization throughout the entire period of observation. Except for testosterone, changes in all stress hormones were attenuated in warmed groups compared to controls. Conclusions. Regarding both features of surgical stress investigated in this study (hypothermia and stress hormone response), the combination of endogenous amino acid-induced thermogenesis and external air warming mattress is most effective in its prevention.

The article presents the study of the bioelectric potential of forest biotopes of Pinus silvestris to evaluate the possibility of their usage as a bioelectricity source. The increase of bioelectric potential in dry soils independent of moisture level was revealed. The positive effect of soil humidity on the generation of bioelectric potential was shown. Insignificant daily and seasonal fluctuations of bioelectric parameters of forest biotopes open their prospects as an important source of renewable energy.

The main approaches to the detection of soil contamination by petroleum products using bioindication were analyzed. Necrosis of leaves of woody plants near sludge accumulators was recorded. To assess the possibility of dendroindication of soil contamination, 3 species of trees distributed on the territory of Bytkiv-Babchensky oil and gas field were selected. According to the results of the Fisher-Snedekor test, the influence of the concentration of oil products in the soil on the necrosis of tree leaves was confirmed, which confirms the possibility of using a dentroindication to detect soil contamination with oil products.

The main sources of soil pollution due to the development of oil and gas fields are analyzed. It is shown that the main sources of oil products entering the soil are sludge accumulators and drilling barns. A new construction of a drilling barn and a scheme of reclamation of the existing ones are proposed. The implementation of such developments will minimize the ingress of oil-containing fluids into the soil and increase the level of environmental safety of oil and gas development processes.

The article provides a detailed review of the problem of deforestation, which in recent years has become uncontrolled. The main causes of forest damage are analyzed, among which the most well-known are climate change, diseases and pests. The losses of forestry as a result of tree diseases, which are large-scale and widespread in other countries, are given. The solution of these problems is possible under the condition of high-quality monitoring with the involvement of automated remote sensing tools and modern methods of image analysis, including artificial intelligence approaches such as neural networks and deep learning. The article proposes an approach to automatic localization and recognition of trees affected by drought, which is of great practical importance for environmental monitoring and forestry. A fully connected convolutional model of deep learning using the tensorflow and keras libraries has been developed for localization and recognition. This model consists of a detector network and a separate classifier network. To train and test the proposed network based on images obtained by remote sensing, a training database containing 8500 images was created. A comparison of the proposed model with the existing methods is based on such characteristics as accuracy and speed. The accuracy and speed of the proposed recognition system were evaluated on a validation sample of images, consisting of 1700 images. The model has been optimized for practical use with CPU and GPU due to pseudo quantization during training. This helps to distribute the values of the weights in the learning process and bring their appearance closer to a uniform distribution law, which in turn allows more efficient application of quantization to the original model. The average operating time of the algorithm is also determined. In the Visual C++ environment, based on the proposed model, an expert program has been created that allows to perform the ecological monitoring and analysis of dry forests in the field in real time. Libraries such as OpenCV and Direct were used in software development, and the code supports object-oriented programming standards. The results of the work and the developed software can be used in remote monitoring and classification systems for environmental monitoring and in applied tasks of forestry.
