Authors: Ferluga Loredana
Published: May 2019

Resumen. En este artículo se ofrece un marco relativo a la protección de los trabajadores homosexuales en el ámbito comunitario e italiano, poniendo de relieve que la realización del principio de igualdad entre trabajadores se traduce en el problema de la efectividad de las normas. A este respecto, el legislador ha conseguido resultados significativos en términos de igualdad. Sin embargo, podrían lograrse resultados más significativos, tanto en relación con el acceso al mundo laboral como a otros aspectos de la relación laboral, mediante la creación de organismos específicos, la adopción de medidas positivas y el papel que las organizaciones sindicales pueden desempañar, con el fin de reducir las diferencias respecto de los grupos víctimas de tratos discriminatorios.Palabras clave: protección de los trabajadores, discriminación, orientación sexual, régimen probatorio, régimen de sanciones.Abstract. This paper examines the Community and italian national rules on protection of homosexual workers, highlighting how the realization of the principle of equal treatment between workers relates to the effectiveness of the protection. About this, the legislator has achieved significant results; however, others could be obtained through the creation of specific organs, positive actions and trade union organizations that have an important role to reduce differences among the victims of discriminatory treatment groups.Keywords: work protection, discrimination, sexual orientation, probative system, sanction system.

Authors: Chacón Martínez Katherine M.
Published: May 2019

ResumenDurante los últimos 20 años, el desarrollo del paradigma de “diseño urbano inclusivo” ha presentado nuevos retos en la planificación urbana frente a la implementación del componente de accesibilidad universal. Ante ello, Ecuador y España han trabajado en la construcción de  legislaciones específicas, normativas, ordenanzas y herramientas técnicas que han dado paso al establecimiento de parámetros de obligatorio cumplimiento en todos los espacios, más aún en lugares de cohesión social como plazas, calles y parques. Al respecto, la presente investigación se enmarca en el análisis de accesibilidad universal de las plazas del Centro Histórico madrileño a fin de identificar los niveles de esta condición y reconocer si se está cumpliendo con los requisitos mínimos o atendiendo a las diferentes tipologías de discapacidad existentes. Tras realizar un estudio normativo que denota las similitudes en parámetros técnicos entre las legislaciones de Ecuador y España, se recurrió a la “Metodología  Ecuatoriana para la Elaboración de Planes de Accesibilidad Universal” basada en la normativa ISO 21542 de “Accesibilidad al Entorno Construido” para la evaluación de los espacios. Considerando los  resultados obtenidos se establece que existen fallas en el diseño que pueden ser corregidas con el objeto de generar una ciudad más inclusiva.AbstractDuring the last 20 years, the development of the "Inclusive Urban Design" paradigm has presented new challenges in urban planning in regard to the implementation of the universal accessibility component. In response, Ecuador and Spain have worked on the construction of specific legislation, regulations, policies and technical tools that have led to the establishment of mandatory parameters in all spaces, especially in places of social cohesion such as squares, streets and parks. In this regard, this research is framed in the analysis of universal accessibility of the Madrid Downtown Squares in order to identify the levels of this condition and recognize that the fulfillment is based on the minimum requirements or attending the different typologies of the existing disability. After carrying out a normative study that shows the similarities in technical parameters between the legislations of Ecuador and Spain, the "Ecuadorian Methodology for the Elaboration of Universal Accessibility Plans" based on the ISO 21542 standard of "Accessibility to the Built Environment" for the evaluation of the spaces was used. Considering the results of the study, there are flaws in the design which can be improved in order to generate a more inclusivecity.

THE PLACE OF SENSE PERCEPTION IN 13TH-CENTURY ENCYCLOPAEDIAS: TWO DIFFERENT READINGS OF ARISTOTLE?
Authors: Ortuzar Escudero María José
Published: May 2019

Several studies have approached sense perception in the encyclopaedias of Thomas of Cantimpré, Bartholomew the Englishman, and Vincent of Beauvais. A comparative analysis of these encyclopaedias shows that all of them arrange sense perception in accordance with the expositions on the soul and with human and animal anatomy. Yet there are significant differences in how they treat the objects of sensation: Thomas does not refer to them at all, Bartholomew considers them to be “accidents,” and Vincent deals with them separately when discussing the features of the sensible world. These differences, I argue, respond to two different readings of Aristotle.

Bawang merah merupakan salah satu komoditas sayuran yang mempunyai peran strategis bagi perekonomian Indonesia. Untuk meningkatkan produksi bawang merah, petani menggunakan beberapa input produksi. Perubahan harga bawang merah akan berdampak pada penawaran output dan permintaan input. Penelitian bertujuan untuk mengetahui pengaruh perubahan harga output dan harga input terhadap penawaran output dan permintaan input usahatani bawang merah di Kabupaten Demak, Jawa Tengah. Penelitian dilaksanakan di Desa Raji, Kecamatan Demak, Kabupaten Demak pada bulan September – Desember 2016. Penelitian menggunakan data primer yang dikumpulkan melalui metode survey terhadap 30 responden. Data dianalisis dalam bentuk pangsa permintaan input dengan metode Seemingly Unrelated Regression (SUR). Hasil penelitian menunjukkan bahwa penawaran bawang merah elastis terhadap perubahan harga bawang merah dan harga umbi benih, namun kurang elastis terhadap perubahan upah tenaga kerja, serta tidak elastis terhadap perubahan harga pupuk. Permintaan input (umbi benih, pupuk, dan tenaga kerja) bersifat elastis terhadap harga masing-masing input tersebut, dan sebagian besar bersifat inelastis terhadap harga input lainnya. Oleh karena itu untuk meningkatkan penawaran bawang merah, pemerintah seyogyanya mampu menjaga stabilisasi harga bawang merah dan mendorong menggunakan biji bawang merah (true seed shallot) sebagai alternatif untuk mengurangi pemakaian benih umbi bawang merah.

Abstract

Shallot is one of the vegetable crops that have a strategic role for the Indonesian economy. To increase the production of shallot, the farmers using several of input production. Changes of shallot would have an impact to output supply and input demand. This study aimed to determine the effect of changes in input and output prices to output supply and input demand of shallot farming. The study was conducted in Raji Village, Demak Subdistrict, Demak District in September - December 2016.  Primary data was collected through survey method by interviewing 30 respondents. The data was analyzed in the form of input demand share by Seemingly Unrelated Regression (SUR) method.  The results showed that supply of shallot is elastic to the price changes of shallot and price of seed bulbs, but less elastic to changes in labor wages and inelastic to changes in fertilizer prices. Demand for production input is elastic to the price of each input, and are largely inelastic with respect to other input prices. Therefore, to increase the shallot supply, the Government should be able to maintain the stabilization of shallot prices and encourage the use of true seed shallot as an alternative to reduce the use of shallot seeds.

SUPPLY CHAIN ANALYSIS OF MADURA TOBACCO COMMODITIES

 

ABSTRACT

Product of Madura tobacco is one of the plantation commodities which is widely cultivated by Madurese farmers. In fact, though Madura tobacco farmers still could not sell their tobacco at a higher price. This is due to the supply chain of Madura tobacco sales which has a long network. There are several intermediate traders in the supply chain network and each intermediate trader takes sales profits as well. This research aims to analyze and remodel the supply chain mechanism for Madura tobacco sales. This study employed a SWOT analysis and supply chain analysis. Data were obtained by conducting FGDs and interviews. The research results from a new model of the sales supply chain for Madura tobacco by creating a marketplace. It is expected that this work can be useful as an input for further study in designing and building a marketplace.

Background: Anti-CD3 immunotherapy was initially approved for clinical use for renal transplantation rejection prevention. Subsequently, new generations of anti-CD3 antibodies have entered clinical trials for a broader spectrum of therapeutic applications, including cancer and autoimmune diseases. Despite their extensive use, little is known about the exact mechanism of these molecules, except that they are able to activate T cells, inducing an overall immunoregulatory and tolerogenic behavior. To better understand the effects of anti-CD3 antibodies on human T cells, PBMCs were stimulated, and then, we performed RNA-seq assays of enriched T cells to assess changes in their gene expression profiles. In this study, three different anti-CD3 antibodies were used for the stimulation: two recombinant antibody fragments, namely, a humanized and a chimeric FvFc molecule, and the prototype mouse mAb OKT3.
Results: Gene Ontology categories and individual immunoregulatory markers were compared, suggesting a similarity in modulated gene sets, mainly those for immunoregulatory and inflammatory terms. Upregulation of interleukin receptors, such as IL2RA, IL1R, IL12RB2, IL18R1, IL21R and IL23R, and of inhibitory molecules, such as FOXP3, CTLA4, TNFRSF18, LAG3 and PDCD1, were also observed, suggesting an inhibitory and exhausted phenotype.
Conclusions: In conclusion, we used a deep transcriptome sequencing method for comparing three anti-CD3 antibodies in terms of Gene Ontology enrichment and immunological marker expression. The present data showed that both recombinant antibodies induced a compatible expression profile, suggesting that they might be candidates for a closer evaluation with respect to their therapeutic value. Moreover, the proposed methodology is amenable to be more generally applied for molecular comparison of cell receptor dependent antibody therapy.

Published: May 2019

Purpose Flipped classroom is a new teaching model which has received a large amount of attention, but the overall acceptability and effectiveness of this approach in different fields of medical education is still controversial. The purpose of this study was to evaluate the acceptability of the flipped classroom in ophthalmology clerkship teaching.
Methods A learning model of a traditional lecture-based approach was changed to a flipped classroom approach for a group of 5-year Clinical Medicine Program students. The flipped classroom included provided pre-session learning resources and objectives before each weekly session. In-session activities emphasized knowledge application and active learning strategies. Data regarding students’ acceptability of the new approach was obtained by anonymous questionnaires that students filled out immediately after class.
Results Feedback was received from 94/94 (100%) medical students. 62.8%(59/94) of respondents preferred the flipped classroom approach over the traditional approach. Interacting with peers and needing more time/effort for preparation were the aspects liked most and least (respectively) for the flipped classroom by students. Flipped classroom was considered better in helping to train students' ability in clinical problem solving, the search and study of literature, cooperating with others, academic exchange, and self-directed learning when compared with the traditional approach. The flipped classroom approach was thought to be a more effective and inspiring way of teaching (P<0.001). Both males and females thought the flipped classroom was a useful way to help students find and solve problems, consider problems comprehensively, learn from literature, and cooperate with others.
Conlusions The flipped classroom has a good acceptability in ophthalmology clerkship teaching. Further evaluation is needed when it be implemented
Development of domain-specific epistemological beliefs of physiotherapists: A longitudinal study
Authors: Bientzle Martina , Cress Ulrike , Kimmerle Joachim
Published: May 2019

Background

Epistemological beliefs (EBs) and therapeutic health concepts are two important factors of influence that affect how healthcare professionals deal with treatment-relevant medical information. A previous investigation compared physiotherapy students’ EBs and therapeutic health concepts with those of professionals in a cross-sectional study. That study design, however, did not allow for any conclusions about the temporal development of these concepts. This shortcoming has been addressed in the study presented here.

Methods

In a longitudinal study, physiotherapists filled in a questionnaire that measured their personal EBs about physiotherapy and about medicine, as well as their biomedical and biopsychosocial therapeutic health concepts. The participants were first examined during their medical training. The follow-up measure was 3 years later when the participants had become professional physiotherapists. We examined the development of their EBs using paired sample t-tests.

Results

The analysis was based on 41 participants who filled in the questionnaire at both time points and were working as physiotherapists at the time of the second measurement. We found a development of physiotherapy-related and a development of medicine-related EBs: Physiotherapy-related as well as medicine-related EBs were more sophisticated when physiotherapists had already entered the working world than during their physiotherapy training. Due to psychometric problems of the scales, we could not analyze the development of their therapeutic health concepts.

Conclusions

EBs are an important factor for (lifelong)learning. We found that physiotherapy-related and medicine-related EBs developed similarly in both domains. This is an indication that the temporal development of EBs is an expression of professionalization of healthcare personnel in their occupational field. Our findings demonstrate that the development of EBs is not completed at the end of vocational training; it appears to be a continuing development throughout one’s working life.

Published: May 2019

O conforto térmico mantém uma íntima relação com a qualidade de vida e a produtividade de todos os seres vivos, pois está relacionado com o seu grau de satisfação e acomodação com a temperatura ambiente. Assim, o presente artigo objetiva demonstrar como os materiais utilizados em uma construção interferem na variação da temperatura, consequentemente no conforto térmico e na ecoeficiência de um ambiente. Para isto criou-se uma planilha de dados, que mostra a variação da temperatura ao longo de um dia em um cômodo construído de 16 m². Com estes dados é possível obter informações sobre como o tipo de bloco, reboco e materiais isolantes interferem no conforto térmico de um edifício. A análise dos dados não mostrou grandes variações de temperatura para blocos comumente utilizados, contudo, concluiu-se que dependendo do material utilizado na construção pode-se interferir na sua ecoeficiência.

A estrutura do solo desempenha relação com os fatores de crescimento vegetal (água, ar, calor, nutrientes e resistência à penetração de raízes), sendo essencial a manutenção e/ou melhoria dos seus atributos. O presente estudo objetivou avaliar as frações inorgânicas do solo e analisar suas inter-relações com atributos estruturais. A pesquisa ocorreu no período de agosto de 2017 a agosto de 2018, sendo realizada a coleta de amostras de solo com estrutura deformada e indeformada, nas classes de Latossolo, Chernossolo, Cambissolos e Neossolo, no Projeto de Assentamento Terra da Esperança, situado no Município de Governador Dix-Sept Rosado, Região Semiárida do Rio Grande do Norte. Foram determinados os atributos texturais (areia, silte e argila), macroporosidade, microporosidade, porosidade total calculada, porosidade total determinada, porosidade de aeração, densidade do solo, umidade gravimétrica e umidade volumétrica. Os resultados foram interpretados utilizando a técnica da estatística multivariada na distinção dos ambientes. Foram constatadas correlações significativas entre a densidade do solo e as variáveis densidade de partículas, porosidade total determinada, porosidade total calculada, microporosidade, macroporosidade, porosidade de aeração e a fração argila. A porosidade total determinada apresentou correlação com a microporosidade, nos Cambissolos, evidenciando restrições à aeração. A microporosidade e a densidade do solo obtiveram correlação positiva com a fração argila, o que refletiu nos atributos estruturais, para todas as classes estudadas, com exceção do Latossolo. Conclui-se que a fração argila foi eficiente na distinção dos ambientes, apresentando correlações significativas com os atributos densidade do solo, porosidade total determinada, porosidade total calculada, microporosidade, macroporosidade e porosidade de aeração. Os ambientes para as classes de Cambissolos foram discriminados pela fração argila, enquanto o Neossolo, pela porosidade total determinada e o Chernossolo pelo silte, sendo um indicativo de solo jovem, pouco intemperizado e facilmente disperso, susceptível ao processo erosivo. A análise multivariada foi eficiente na distinção dos ambientes, evidenciado as inter-relações entre os atributos estruturais e as frações inorgânicas do solo.

Published: May 2019

A gestão dos resíduos sólidos urbanos (RSU) no Brasil tem evidenciado graves problemas, sendo alvo de muitas críticas. Contudo, poucas iniciativas ou ideias buscando mitigar a problemática têm sido apontadas. O Município de Barra do Mendes, localizado no sertão baiano, apresenta um cenário similar à da maioria dos municípios brasileiros: existe a produção de uma grande quantidade de resíduos e a inexistência de uma gestão eficiente. Para entender melhor a realidade do Município de Barra do Mendes em relação a gestão dos seus resíduos sólidos, realizou-se observações in situ, análise bibliográfica baseada em leis e normas e a aplicação de questionários do tipo autoaplicado. Diversos problemas relacionados ao manejo dos resíduos sólidos puderam ser registrados no município, desde o transporte, despejo, armazenamento e queima de forma inadequada até a localização inapropriada do lixão, circunstâncias que põem em risco a saúde da população e o meio ambiente. Entretanto, verificou-se que pouca atenção vem sendo dada ao assunto no município, bem como existe pouca apropriação por parte dos morados acerca da coleta, transporte e descarte dos resíduos sólidos produzidos. Salienta-se, portanto, que é preciso pensar na questão dos RSU como um caso de saúde pública, que tem como principais entraves a falta de boa vontade política em priorizar a questão e, consequentemente, disponibilizar verbas necessárias para o desenvolvimento de projetos socioambientais direcionados a conscientização dos habitantes e para a criação de um sistema de tratamento adequado para descarte dos resíduos. Assim, esta discussão consiste em uma importante ferramenta para gestão dos RSU no município.

This research has been carried out to determine diversity and abundance of Rotifera in Kadıköy Reservoir. For this purpose, Rotifera and water samples were collected monthly from March 2010 to February 2011 at three different stations in the reservoir. A total of 33 species from Rotifera were determined in the qualitative evaluation of samples taken from the reservoir. The quantitative evaluation of the Rotifera samples revealed presence of an average of 70 472 ind m-3 in Kadıköy Reservoir. The maximum number of Rotifera were recorded at 1st station (81 819 ind m-3); in May (100 901 ind m-3) and in spring season (83 458 ind m-3). Asplanchna priodonta, Brachionus angularis, Filinia terminalis and Keratella cochlearis sampling in all months were found to be the most common species during the study. When we evaluate the species identified in the reservoir, the distribution of the individuals that make up the Rotifera fauna and physical-chemical parameters as a whole, it has been concluded that Kadıköy Reservoir is in meso-eutrophic character in terms of Rotifera.

Bitki materyali olarak Amasya iline bağlı Suluova ilçesinde yetişen ekmeklik buğday çeşidi Ceyhan 99 kullanıldı. Buğday bitkileri çimlendikten sonra saksılara aktarılarak, laboratuvarda 18/6 saat ışık/karanlık rejimi altında yetiştirildi. Buğday fideleri iki gruba ayrılarak birinci gruba 0.10, 0.20, 0.30, 0.50 mM krom çözeltisi, ikinci gruba ise aynı konsantrasyonlarda krom çözeltisi ve 1.5 mg L-1 FA çözeltisi uygulandı. Yapılan çalışmada krom stresi uygulamasına bağlı olarak klorofil a, klorofil b, toplam klorofil ve karotenoid içeriğinde yalnızca krom uygulanan grupta, FA+krom uygulanan gruba göre azalma tespit edilmiştir. Buna karşın yalnızca krom uygulanan grupta, FA+krom uygulanan gruba göre Klorofil a b-1 oranı ve MDA içeriğinde artış belirlenmiştir. Bu çalışma FA’in buğday bitkilerinde krom stresine karşı önemli bir role sahip olduğunu göstermektedir. Elde edilen verilere göre, buğday bitkilerine FA uygulamasının kromun zararlı etkilerini azaltabileceği görülmüştür.

This study includes on the taxonomic evaluation of morphological and anatomical features of seeds belonging to Iris taxa, which are I. suaveolens, I. sintenisii, I. foetidissima and I. germanica scattered in Turkey. Morphological features like dimension, shape, colour, and surface ornamentation types of seeds have studied by light and scanning electron microscopes. The structure and thicknesses of testa and parenchyma layers in seeds have examined anatomically. The obtained results show that the color, shape, testa structure and thickness of the seeds of the examined taxa are different in some respects. Furthermore, the surface ornamentations are somewhat diverse for the studied taxa at the interspecific level. As a result, it has been determined that the examined morphological and anatomical characteristics of the seeds show variations with some exceptions, and this situation has a taxonomic importance.

Metabolic processes in living organisms are closely related to the catalytic activity of enzymes. Inhibition or induction of enzymes leads to toxicities and metabolic interactions. This studyaims to contribute to the growing drug design field by studying PON1-phenolic compound interactions. For this purpose, the paraoxonase-1 enzyme was purified from fresh human serum byusing rapid and different chromatographic techniques. Additionally, it was investigated the inhibitory effects of some phenolic substances on the PON1 and was found that the purified enzyme had themolecular weight of 43 kDa and the specific activity of 3945.15 EU mg-1. These compounds showed potent inhibition against PON1, especially homovanillic acid exhibited a significant inhibition profileagainst PON1 with an IC50 value of 13.84±0.08 mM. Ki constants were 6.10±0.26 mM for homovanillic acid and 16.96±0.76 mM for phloridzin dihydrate. Homovanillic acid had competitiveinhibition while the phloridzin dihydrate inhibited the PON1 as non-competitive. Also, molecular docking computations were performed by using the Glide XP mode. Glide energy of the homovanillicacid determined to be -23.95 kcal mol-1.

The Seebeck coefficient S and the electrical conductivity σ of solid solutions based on bismuth telluride with substitutions in Bi and Te sublattices were studied at pressures up to 12 GPa at room temperature. It is shown that with increasing pressure, the electrical conductivity increases and, despite the decrease in the Seebeck coefficient, an increase in the power factor (S^2)σ is observed in p-Bi0.5Sb1.5Te3 and n-Bi2Te1.65Se0.65S0.7 solid solutions. The maximum increase in the power factor was found for n-Bi2Te1.65Se0.65S0.7 in the pressure range of 3−4 GPa, corresponding to the electronic topological phase transition. The investigated solid solutions were used in the model of a thermoelectric module with adjustable mechanical stress applied to thermoelements.

Abstract
The optical properties of plastically deformed ZnS∙0 single crystals have been studied on the basis of bandanticrossing theory. The difference in oxygen concentration in the surface layer and in the bulk of the sample was found from an analysis of the results of cathodoluminescence and scanning electron microscopy. This made it possible to explain the position of the fundamental absorption edge and exciton spectra. Dynamics of the shift of the self-activated luminescence at deep A-centers bands during deformation recrystallization with increasing concentration of dissolved oxygen is shown. The restriction of the spectral range of the appearance of self-activated luminescence at shallow levels is established. The nature of the emission bands in the wavelength range 336-350and 364-390 nm has been discovered. The results can be used both to refine the energy model of ZnS∙O and in the case of practical use of the structure-sensitive properties of zinc sulphide crystals.

The introduction of CsPbBr3 nanocrystals into the ZnO porous matrix leads to the appearance of a positive photoconductivity response in the visible spectral range. Measurement of the spectral dependences of absorption, photoluminescence and photoconductivity showed that the shape and position of the photoluminescence peak are associated with defects in CsPbBr3. Analysis of the kinetics of photoconductivity relaxation shows the possibility of accelerating the process of recombination of photoexcited charge carriers by more than an order of magnitude. The mechanisms responsible for the effect are discussed.

Asymmetrical double InAs/InAsSb/InAsSbP heterostructures are grown by metalorganic vapor-phase epitaxy. Two types of light–emitting diodes (A and B) were created on basis of grown heterostructures with emission peak at 4.1 µm and 4.7 µm, respectively. The current–voltage and electroluminescent characteristics of light–emitting diodes are investigated at room temperature. When operating at 50 % duty cycle mode (frequency − 512 Hz) with a current of 250 mA, light–emitting diodes A and B produced the optical power of 24 μW and 15 μW, respectively. Under the pulse operation (frequency − 512 Hz, duration − 1 μs) with a current of 2.1 A, the optical power of light–emitting diodes А and B reached the values of 158 μW and 76 μW, respectively. The developed light–emitting diodes can be used as high-effective radiation sources in optical absorption sensors for detection of carbon dioxide and carbon monoxide in the atmosphere.

The work is devoted to the study of the formation features of high-quality closed modes based on total internal reflection effect in rectangular resonators of large (up to thousands wavelengths) size based on InGaAs/GaAs/AlGaAs laser heterostructures. Features of the spectral composition and spatial configurations of closed mode structures are experimentally investigated. The presence of frequency combs in the spectra was demonstrated and their correspondence to separate spatial configurations of closed modes was shown. The effect of a change in pumping and temperature on the mode composition is also considered.

An experimental study of the avalanche breakdown of
the p−n-junction was carried out in order to study the temporal
distribution of microplasma pulses. It was revealed that the
observed appearance microplasma noise is not described in the
existing model processes that occur during avalanche breakdown
of p−n-junction. Using simulation, a computer model was
developed that clarifies the mechanisms of microplasma instability
and takes into account the electrical and temperature dependences
of avalanche breakdown, which is consistent with the results of
experiments.

AbstractFor the first time, comprehensive comparative investigations of ultraviolet photodetectors with Cr Schottky barriers formed on 4 H -SiC epitaxial layers are carried out by the X-ray and optical methods before and after irradiation with 15-MeV protons with fluences in the range of (1–4) × 10^12 cm^–2. When increasing the fluence of proton irradiation, the formation of localized regions with negative deformation is observed along with the unperturbed silicon-carbide matrix. Agreement between the X-ray and optical studies is obtained, which makes it possible to explain the features of the spectral changes in the photosensitivity of detectors in the range of 200–400 nm with an increase in the fluence of proton irradiation. The ultraviolet Cr/4 H -SiC photodetectors withstand irradiation by 15-MeV protons with a fluence of 4 × 10^12 cm^–2 virtually without any changes in the photosensitivity due to the gettering of simple defects by cluster and amorphous formations, which lead to partial structural improvement of the irradiated material.
