Rapid separation and extraction of radioactive analytes onto filters and surfaces
Authors: Gonzáles E. R. , Klingensmith A. L. , Peterson D. S. 
Published: August 2020

Abstract
This paper presents a radiochemical procedure that combines radiochemical sample preparation and analyte separation to provide a rapid sample preparation method. Extractive ligands are prepared in a polymer matrix. This system can be immobilized on a surface or on a filter. Filters allow rapid sample uptake due to the movement of the analyte through the filter material. These approaches offer fast uptake kinetics, high material loading, and good selectivity. These systems have been demonstrated for the rapid extraction of plutonium and americium from solution and their subsequent analysis by alpha spectrometry, with no additional sample preparation required, thus eliminating extensive wet chemical processes that would otherwise be necessary. We have evaluated the extraction efficiency that can be obtained and have shown that these systems can provide for alpha spectrometry peak widths near what can be obtained using traditional techniques such as electroplating. We have also demonstrated Polymer Ligand Films (PLFs) for the selective extraction of plutonium from a solution prepared from a soil digest.
Preparing a laboratory for radioanalytical emergency response

Abstract
As the state of the nation's ability to respond to a radiological event is examined, it has become apparent that both capacity and capability are lacking. Department of Homeland Security National Planning Scenario #11 is designed to address the planning activities for the response to an attack using radiological dispersal devices. The scenario details show that the cleanup activity will take several years, and that there will be between 360000 and 1000000 environmental samples in the first year. Based on existing capacity and capabilities it would take four to six years to analyze the samples generated at the lower end of the sample range.
The Environmental Protection Agency (EPA) has been given responsibility for the remediation activities following a radiological event, and has awarded cooperative agreements to several laboratories to start the process of developing capacity and capabilities. The Connecticut Department of Public Health Laboratory (DPHL) was awarded one of the cooperative agreements. The DPHL has started activities to further those goals by investigating and implementing procedures to ensure that samples with activity higher than normal background can be processed safely, as well as implementing more rapid methods for radiochemical analysis. The DPHL already served as the primacy radiochemistry laboratory for several New England states and thus had a solid foundation to build upon. The DPHL has taken a process flow approach in preparing for radiological emergency response and recommends that radioanalytical laboratories that are reviewing their roles in such a response:

• Ensure that their Nuclear Regulatory Commission licenses allow for appropriate radioisotope types and activities;

• Develop procedures and processes to ensure that samples with higher activities can be processed safely, with due regard for sample screening and aliquanting samples;

• Provide for enhanced radioanalytical contamination control, with careful consideration of sample flow and breaking the laboratory into zones with controlled access;

• Address personnel safety by enhancing training, adding real time dosimetry to exposure monitoring protocols, and reviewing personal protective equipment and hygiene protocols with staff;

• Develop plans for spills and decontamination, as well as for increased monitoring of laboratory areas;

• Plan for secure sample storage;

• Exercise the plan.
Nuclear field shift effect of lead in ligand exchange reaction using a crown ether

Published: August 2020

Abstract
Lead isotopes were fractionated by the liquid-liquid extraction technique between an aqueous phase and a crown ether. After purification by ion-exchange chemistry, the 207Pb/206Pb and 208Pb/206Pb isotopic ratios were measured by multiple-collector inductively coupled plasma mass spectrometry (MC-ICP-MS). Isotope fractionations > 0.05‰ have been found. The conventional equilibrium mass-dependent isotope effect estimated by an ab initio calculation was smaller than the Pb isotope fractionation experimentally obtained. Conventional mass-dependent isotope fractionation is not a valuable explanation for our results. The nuclear field shift effect, which results from the isotopic change in the nuclear size and shape, was also estimated by an ab initio method combined with a finite nucleus model. The nuclear field shift effect calculated was in agreement with our experimental results. Therefore, this study reports the first nuclear field shift effect of Pb in an equilibrium ligand exchange reaction.

Published: August 2020

AbstractTrichogramma brassicae (Bezdenko) are egg parasitoids that are used throughout the world as biological control agents and in laboratories as model species. Despite this ubiquity, few genetic resources exist beyond COI, ITS2, and RAPD markers. Aided by a Wolbachia infection, a wild-caught strain from Germany was reared for low heterozygosity and sequenced in a hybrid de novo strategy, after which several assembling strategies were evaluated. The best assembly, derived from a DBG2OLC-based pipeline, yielded a genome of 235 Mbp made up of 1,572 contigs with an N50 of 556,663 bp. Following a rigorous ab initio-, homology-, and evidence-based annotation, 16,905 genes were annotated and functionally described. As an example of the utility of the genome, a simple ortholog cluster analysis was performed with sister species T. pretiosum, revealing over 6000 shared clusters and under 400 clusters unique to each species. The genome and transcriptome presented here provides an essential resource for comparative genomics of the commercially relevant genus Trichogramma, but also for research into molecular evolution, ecology, and breeding of T. brassicae.
Optimal Detection of Bilinear Dependence in Short Panels of Regression Data
Authors: Lmakri Aziz , Akharif Abdelhadi , Mellouk Amal 
Published: August 2020

In this paper, we propose parametric and nonparametric locally andasymptotically optimal tests for regression models with superdiagonal bilinear time series errors in short panel data (large n, small T). We establish a local asymptotic normality property– with respect to intercept μ, regression coefficient β, the scale parameter σ of the error, and the parameter b of panel superdiagonal bilinear model (which is the parameter of interest)– for a given density f1 of the error terms. Rank-based versions of optimal parametric tests are provided. This result, which allows, by Hájek’s representation theorem, the construction of locally asymptotically optimal rank-based tests for the null hypothesis b = 0 (absence of panel superdiagonal bilinear model). These tests –at specified innovation densities f1– are optimal (most stringent), but remain valid under any actual underlying density. From contiguity, we obtain the limiting distribution of our test statistics under the null and local sequences of alternatives. The asymptotic relative efficiencies, with respect to the pseudo-Gaussian parametric tests, are derived. A Monte Carlo study confirms the good performance of the proposed tests.
Implementación de un Proyecto Pedagógico Productivo (PPP) en el marco de la piscicultura
Authors: Candela Boris , Salazar Jenny Viviana 
Published: August 2020

La enseñanza de la química en la escuela secundaria se ha llevado a cabo desde una perspectiva descontextualizada y focalizada en los contenidos y el profesor, situación que limita la oportunidad a los estudiantes de comprometerse en la construcción de los productos y procesos de la química. Con el ánimo de superar estas restricciones, este estudio se propuso implementar un PPP representado en la piscicultura a fin de asistir a los estudiantes de básica secundaria ciclo II rural, en la comprensión del tópico de las disoluciones junto con el desarrollo de algunas habilidades para la vida. La metodología fue cualitativa e interpretativa por estudios de casos. Esta estuvo configurada por dos fases: planeación e implementación de una secuencia de actividades de aprendizaje, y documentación de los razonamientos y acciones de los estudiantes y el profesor. Los datos provenientes de las diferentes fuentes documentales fueron analizados desde la teoría fundamentada, emergiendo una serie de generalizaciones naturalisticas sustentadas por la afirmación que los PPP de la cría de trucha Arcoíris es una orientación de enseñanza contextualizada, la cual ayudó a los estudiantes a construir no sólo la comprensión del fenómeno de las disoluciones, sino, también, el desarrollo de habilidades como aprender a aprender y el trabajo cooperativo con el objetivo de informar el cultivo de esta clase de peces.
Efecto de la vigilancia Entomológica en la estructuración poblacional de triatoma infestans (hemiptera, reduviidae) de intra y peridomicilio en un área endémica de la Provincia de la Rioja (Argentina).
Authors: Hernández María Laura 
Published: August 2020

Se analiza aquí, la influencia del rociado y vigilancia sobre la estructuración de las poblaciones peri e intradomésticas de T. infestans usando morfología cuantitativa. Las colectas en intra (ID) y peridomicilio (PD) se realizaron sobre una población libre de rociado por 10 años y en poblaciones hasta 8 años post rociado (población con vigilancia y rociado). En pre-rociado, no se observó estructuración poblacional entre ID y PDPost intervención, se detectaron 6 adultos de T. infestans en ID. Estos insectos mostraron similitud morfológica con T. infestans residuales. Los resultados plantean que en presencia de vigilancia entomológica, los ID pueden permanecer libres de T. infestans aún con PD infestados.

Published: August 2020

Artikel ini mencoba menguji keberhasilan peran LSM kepemiluan Komite Independen Sadar Pemilu (KISP) dalam membentuk desa anti politik uang (desa APU) sebagai agenda perlawanan terhadap praktik politik uang di Desa Sardonoharjo, Kecamatan Ngaglik, Kabupaten Sleman, Daerah Istimewa Yogyakarta. Artikel ini menggunakan metode penelitian kualitatif dengan pendekatan deskriptif yang menggunakan instrumen wawancara terhadap informan terkait dan menggunakan instrumen observasi participan pada objek penelitian sebagai data primer, sedangkan data sekunder diperoleh dari studi perpustakaan terkait fokus penelitian seperti buku, jurnal nasional/internasional, laporan, dokumen dan sumber tertulis lainya yang terkait dengan fokus penelitian. Artikel ini mengarahkan kepada 4 kesimpulan pokok: 1.) Peran KISP sebagai konseptor pembentukan Desa APU meliputi deklarasi Desa APU untuk melawan praktik politik uang, pembentukan tim, sosialisasi dan pendidikan tentang bahaya politik uang, hingga pada pembuatan modul Desa APU dan pembuatan stiker keluarga anti politik uang. 2.) Masih ada penolakan oleh masyarakat sekitar terkait gerakan perlawanan politik uang. 3.) Peran KISP dalam pembentukan Desa APU untuk melawan praktik politik kurang efektif mengurangi terjadinya praktik politik uang, meskipun tidak ditemukan laporan mengenai praktik politik uang di Desa Sardonoharjo hal ini tidak mengindikasikan keberhasilan program Desa APU. 4.) Hal ini disebabkan karena politik uang sudah menjadi hal yang biasa dikalangan masyarakat sekitar desa tersebut dan sikap kurang tegas dari pihak perangkat desa, serta kurangnya partisipasi dari pihak Bawaslu Kabupaten Sleman pada tahapan sosialisasi.

The Model of the Family and Family Upbringing Propagated By the Local Press of the Greater Poland Region in the Second Republic of Poland
Authors: Piwowarczyk Mirosław 
Published: August 2020

During the interwar period, local press played a major role in the socio-cultural life of the local communities in the Greater Poland region.
With the high number of periodicals, the local press had a substantial influence on the socio - cultural life and education in the towns and cities of the region. It played a major educational role. It had an educational influence on the local communities, because the periodicals propagated models and forms of social and family life among them. The political and ideological stance of most of the periodicals was clearly defined as Catholic and national, therefore, the models of social activities that they promoted were consistent with this worldview. In consequence, the press propagated educational principles and ideas on upbringing, models of the family, a wife - mother, a husband - father, and children compatible with Catholic Social Teaching and the ideology of National Democratic political parties (Stronnictwo Narodowe [National Party], Narodowa Demokracja [National Democracy]).
The model of the farmers’ families and those of the Middle Class was consistent with the clearly defined National Democratic ideology prevalent among the members of the local communities of Greater Poland, with its deep-rooted Catholicism, and with the experiences (characteristics, qualities) that became established in the times of the Partitions of Poland.
The 21st Century Family in the Context of the Challenges of Modernity – Single Parenthood in Macro, Meso, and Micro Perspective
Authors: Jurczyk - Romanowska Ewa 
Published: August 2020

The purpose of the present paper is to compare three levels of discourse on the subject of the 21st century family. The macro scale is represented by the ideas of the International Year of the Family + 20, the meso scale – by the postulates of the government of Poland aimed at the implementation of international presumptions in Poland. The reality experienced by single parents and its inherent evaluation of the realization of the government’s postulates constitutes the micro scale. Comparison of the three perspectives allows for a discernment of the shortcomings of the government’s postulates as well as the somewhat superficial character of the undertaken actions.

Nowadays modern competetive labor market situation results the diffuculties to adapt to the younger generation rather than the people with other age groups. People who are trying to employ are being asked much more requirements, that‘s why it’s very important to highlight those motives, which are related to the choice of profession. Beause of the motives, it depends every activity and it’s success. Scientists note, that it is very important to know your motives, that you can adjust and control them; because the intensity, direction of the activity and comunicationcan be changed by changing the motives. In the research there were 115 Lithuanian University of Educational Sciences music pedagogy study program students.Research aim – to examine Lithuanian University of Educational Sciences music pedagogy program selection of the motives and their alteration during the study year.Research objective: to identify the students with music pedagogy bachelor study program selection for their profession motives; to reveal the change of students attitude towards their profession during studying year; find out students fulfillment of their studies and their willingness to work in the educational system.Music pedagogical profession selection of the motives research showed students’ professional orientation and the willingness to be the music teacher. The highest value had cognitive and personal motives. For more than two-thirds of patients it is very important to achieve higher education. The least significant motives are other people – friends, parents, relatives and family traditions – influence.Revealed the change of the respondents’ attitude towards their profession during the study year: the impression and experiences towards their profession changed after practice period; the perception, that the teacher profession is connected with patience, occurs; disclose the need to know pedagogical topics better; passion to work with children and self-expression. More than one-third of the respondent noted, that the need to be the music teacher is their main motive, which is not changing and stimulating to study in the university. However the research resultsshowed that there are some students, who lack in professional purposefulness, which comes out in doubts, emergence of the problems and disappointment. Revealed that the strongest professional purposefulness is during the study years, which been influenced by quality of studies, expectation fulfillment, needs satisfaction and benefit of the practice. Established the satisfaction of the studies: future music teachers during their studies finds perspective of their own subject, finds the meaning to do pedagogical work; self-realizing by communicating with children and by implementing their own creative ideas.
