Authors: Mondal Anubrata , Ghosh Kamalika
Published: December 2019

In the ever-changing world, cultural heritage, especially through documents, plays an important role in a civilized developing country. The documents specially made of paper are organic products and more prone to bacterial formation. From most of the heritage archives, it has been informed/ observed that bacteria destroys the important documents. The conservations of these articles are essential. From the point of view for good lighting system design, one can utilize a photobiological effect of light, i.e., UV range of the light source is killing bacteria too. Experimentation has been carried out on different paper documents with different intensities of UV contents from light sources. The bacteria content in a sample at the initial stage as well as after UV treatments with different intensities have been noted, analyzed, and furnished in this paper. The process shows a successful result as per expectation. If this methodology can be implemented for the conservation of paper archives, it will give a fruitful result for the conservation of our cultural heritage, which is very much valuable for the development of a society.
Why it is Necessary to Revise the Standards of Exhibition Lighting
Authors: Bogdanov Alexei V. , Smirnov Vladimir A.
Published: December 2019

In the modern world, one of the main functions of museums is to organize the preservation of pieces of art and arrange their presentation to museum visitors. Since the modern exhibition is based on the artificial lighting, it is necessary to properly arrange this lighting; otherwise, it can negatively affect the safety of museum pieces. The article sets out the views on the criteria of professional lighting of works of art, as it is always a compromise between the custodians and the lighting engineers. The authors also attempt to disclose the processes of organizing museum lighting and give a generalized description of the standards and rules, which serve as a basis to realize this lighting. The main reasons for the need to rethink these standards and rules (and even to revise them), in connection with the emergence of new LED sources, have been outlined.

Authors: Aladov Andrei V. , Zakgeim Alexander L. , Chernyakov Anton E.
Published: December 2019

Article overviews prospects of application of adjustable polychrome LED luminaires based on RGB mixture principle for museum lighting. Such light sources allow creating of high-quality lighting systems with capability to adjust luminous flux and chromaticity characteristics with a wide range of correlated colour temperatures between 2800 K and 6500 K and high values of all colour rendering indexes: R1-R14. Application of adjustable LED light sources makes it possible to do artificial museum lighting similar to natural environment at the moment of creating of a piece of art by an artist, hence, to make its perception more precise. Possibility to adjust the correlated colour temperature allows creating individual lighting of paintings in compliance with the genre and subject of a work (a portrait, a landscape, time period, etc.). The article also briefly describes major theoretical, circuit design and software aspects of creation of a dynamically adjustable LED system of museum lighting and gives first examples of its application.

İletişimin
temel aracı olan dilin doğru kullanımı, toplumun önemli bir kesiminde, yalnızca
Türkçe öğretmenleri ile dilcilerin sorunu gibi görülmektedir. Oysa dil, her
alanda ve yaşamın her boyutunda, herkes için, sağlıklı iletişim kurmak
açısından yaşamsal öneme sahiptir. 
Öğrencilerin anlama ve anlatma becerileri anadilleri ile
geliştirildiğinden, doğru ve etkin dil kullanımı genel akademik başarı
açısından da ayrıca büyük önem taşımaktadır. Bu çalışmanın amacı, Türkçe dersi
dışında kalan ders öğretmenlerinin, öğrencilerin anadili yeterlilikleri ile
akademik başarıları arasındaki ilişki konusunda farkındalıklarını ortaya
koymaktır. Çalışma nitel bir çalışma olarak planlanmıştır.  Milli Eğitim Bakanlığı’na bağlı ortaokullarda
görev yapan ve rastgele seçimle belirlenen 5., 6., 7. ve 8. sınıf öğretmenleri
ile 2017- 2018 öğretim yılı güz dönemi içerisinde gerçekleştirilmiştir.  Verilerin toplanmasında esneklik ve sorulara
alınan yanıt oranlarında tamlık sağlanabilmesi amacıyla yarı yapılandırılmış
görüşme yöntemi uygulanmıştır. Öğretmen görüşmelerinden elde edilen veriler
doküman analizi yöntemi ile yorumlanmıştır. Çalışma grubuna uzman görüşü
alınarak hazırlanan 5 soru yöneltilmiştir. Bu sorulara verilen cevaplardan elde
edilen bulgular yorumlandığında, 
öğretmenlerin dilin işlevini ve akademik başarıdaki rolünü belli
sınırlar içinde değerlendirdikleri; dil yeterliliği konusunda okuma, okuduğunu
anlama ve yazma becerilerine odaklandıkları; düşünmenin, fikir üretmenin ve
paylaşmanın dil ile gerçekleştiği konusunda yeterli dikkat ve farkındalığa
sahip olmadıkları görülmüştür. Çalışma sonucunda öğretmenlerin öğrenci
başarısını ölçmede yalnızca doğru cevabı seçip işaretledikleri çoktan seçmeli
test kullanmalarının öğrencilerin metin üretme ve çözümlemesine ortam ve olanak
sağlamadığı belirlenmiştir. Buradan hareketle hem ders sürecinde hem de
öğretilenlerin ölçme ve değerlendirilmesinde, her alanda, söze dayalı dilin kullanımına
özen gösterilmesinin ve öğrencide dil yanlışları konusunda dikkat
uyandırılmasının öğrencinin akademik başarısına olumlu etki edebileceği
değerlendirilmiştir.

Published: December 2019

This study describes the surface deformation in lower Jehlum and eastern Potwar using remotely sensed Shutter Radar Topographic Mission (SRTM) Digital Elevation Model (DEM) to identify regional uplift rates. Mapping of active surface deformations help to predict seismic hazards. DEMs are the fundamental input factors that identify the surface geometry and its belongings. These belongings include stream offset, elevation, and slope breaks within a contributing area. This study provides an evidence of tectonic activity and its impact on regional drainage network using SRTM DEM. Various indices including concavity and steepness were computed using power law in steady state conditions. We prepared the drainage network map of the study site showing uplift rates in mm/year. The deflection in stream network proves the existence of active fault in this region which controls the local drainage network. The results prove the relative uplift along Main Boundary Thurst (MBT) and the impact of active tectonic on evolving young organs.

Multi-server queueing system with reserve servers
Authors: Klimenok Valentina I.
Published: December 2019

In this paper, we investigate a multi-server queueing system with an unlimited buffer, which can be used in the design of energy consumption schemes and as a mathematical model of unreliable real stochastic systems. Customers arrive to the system in a batch Markovian arrival process, the service times are distributed according to the phase law. If the service time of the customer by the server exceeds a certain random value distributed according to the phase law, this server receives assistance from the reserve server from a finite set of reserve servers. In the paper, we calculate the stationary distribution and performance characteristics of the system.

Preparation of ethosome was used hot method (40oC) and cool method (30oC). Characterization of ethosomes includes observation of shape and size of vesicles by microscopic method and the vesicles were fractionated by centrifugation then entrapment efficiency (% EE) were measured by spectrophotometric method. Then optimazed theophylline that entrapped in ethosome. Based on the results, ethosomes preparation by hot method were produced Small Unilamellar Vesicle (SUV), the size were 0,0522-0,100 µm, and the highest value of % EE was 98.95%, while ethosomes preparation by cold method were produced Small Unilamellar Vesicle (SUV), the size were 0.0522-0.100 μm, and the highest value of % EE was 99.80%. The optimum concentration of theophylline was entrapped in etosom was 0.1%. It was concluded that cold method was the appropriate method for preparation of theophylline in ethosome as vesicular carrier.Keywords: Etosome, theophylline, vesicular, transdermal

Soft constraints are quite common in real-life applications. For example, in freight transportation, the fleet size can be enlarged by outsourcing part of the distribution service and some deliveries to customers can be postponed as well; in inventory management, it is possible to consider stock-outs generated by unexpected demands; and in manufacturing processes and project management, it is frequent that some deadlines cannot be met due to delays in critical steps of the supply chain. However, capacity-, size-, and time-related limitations are included in many optimization problems as hard constraints, while it would be usually more realistic to consider them as soft ones, i.e., they can be violated to some extent by incurring a penalty cost. Most of the times, this penalty cost will be nonlinear and even noncontinuous, which might transform the objective function into a non-smooth one. Despite its many practical applications, non-smooth optimization problems are quite challenging, especially when the underlying optimization problem is NP-hard in nature. In this paper, we propose the use of biased-randomized algorithms as an effective methodology to cope with NP-hard and non-smooth optimization problems in many practical applications. Biased-randomized algorithms extend constructive heuristics by introducing a nonuniform randomization pattern into them. Hence, they can be used to explore promising areas of the solution space without the limitations of gradient-based approaches, which assume the existence of smooth objective functions. Moreover, biased-randomized algorithms can be easily parallelized, thus employing short computing times while exploring a large number of promising regions. This paper discusses these concepts in detail, reviews existing work in different application areas, and highlights current trends and open research lines.

The aim of this study was to develop a technique easy to apply in order to induce seed-tuber dormancy breakage. Over a two-year study, more than seven dormancy-breaking treatments were tested through evaluating different temperature effects alone or combined with gibberellins application, cutting in half of seed-tubers, and early haulm killing. Three varieties per year were considered: Spunta and Monalisa (medium and long dormancy) in both years, Europa during the first year and Arinda during the second year (both characterized by a short dormancy period). We found firstly that Europa and Arinda promptly responded to thermal treatments, and secondly to the same thermal treatments in combination with the application of gibberellins. Although not easily applicable, especially when a large volume of seed-tubers has to be handled (seed-tuber producers), the cutting in half of the seed-tubers also had a satisfactory result. Notwithstanding that treatments did not perfectly overlap between the two experiments, results were qualitatively similar. Therefore, these findings allow us to conclude that treatment with post-harvest storage at 20 °C, followed by a treatment with gibberellic acid at 38 days from harvesting, is the most efficient in releasing dormancy, in ensuring a good vegetative growth and productive performance at field-level irrespective of the variety.

Neglected and underutilized fruit species (NUFS) can make an important contribution to the economy, food security and nutrition requirement for Sri Lanka. Identifying suitable areas for cultivation of NUFS is of paramount importance to deal with impending climate change issues. Nevertheless, limited studies have been carried out to assess the impact of climate change on the potential distribution of NUFS. Therefore, we examined the potential range changes of NUFS in a tropical climate using a case study from Sri Lanka. We prioritized and modeled the potentially suitable areas for four NUFS, namely Aegle marmelos, Annona muricata, Limonia acidissima and Tamarindus indica under current and projected climates (RCP 4.5 and RCP 8.5) for 2050 and 2070 using the maximum entropy (Maxent) species distribution modeling (SDM) approach. Potentially suitable areas for NUFS are predicted to decrease in the future under both scenarios. Out of the four NUFS, T. indica appears to be at the highest risk due to reduction in potential areas that are suitable for its growth under both emissions scenarios. The predicted suitable area reductions of this species for 2050 and 2070 are estimated as >75% compared to the current climate. A region of potentially higher climatic suitability was found around mid-county for multiple NUFS, which is also predicted to decrease under projected climate change. Further, the study identified high-potential agro-ecological regions (AERs) located in the mid-country’s wet and intermediate zones as the most suitable areas for promoting the cultivation of NUFS. The findings show the potential for incorporating predictive modeling into the management of NUFS under projected climate change. This study highlights the requirements of climate change adaptation strategies and focused research that can increase the resilience of NUFS to future changes in climate.

The aim of this field experiment was to analyze the influence of different nitrogen and sulfur doses on yield as well as the content and uptake of iron (Fe), manganese (Mn), copper (Cu) and zinc (Zn) by spring rye grain. The study was conducted in south-eastern Poland (2009–2011) on Cambisols (WRB 2015), in conditions of low sulfur content in soil. The experiment included four doses of N fertilization (0, 30, 60 and 90 kg ha−1) and two doses of S supplementation (0 and 40 kg ha−1). The analysis showed that fertilization with N and S had a positive effect on the studied features of spring rye. The highest grain yields were found after use of 90 kg N ha−1. The grain of rye fertilized with these doses of N was characterized by the highest concentration and uptake of tested microelements. The supplementation of sulfur in a dose of 40 kg S ha−1 improved the nitrogen effect, because the rye grain yield and the content and uptake of micronutrients (except Mn) by rye grain dry mass increased. The highest yield of spring rye grain and accumulation of Mn and Zn and intake of Mn, Zn and Cu by grain dry mass (DM) were obtained in the vegetation season of 2011, which was characterized by an optimal rainfall distribution. The highest accumulation of Fe and Cu and intake of Fe were obtained in the vegetation season of 2009. Significant correlations were found also between grain yield and the content and uptake of all studied micronutrients. The supplementation of NPK fertilization with sulfur can be a good means of agronomic biofortification for spring rye in order to increase the content and uptake of Fe, Mn, Zn and Cu.

Recessive resistance against potyviruses, such as Potato virus Y (PVY), relies on mutations in the eukaryotic translation initiation factor 4E (eIF4E) or one of its isoforms. The eIF4E1-S mutants of burley tobacco (Nicotiana tabacum L.) exhibit recessive resistance against PVY strains. Here, we developed a TILLING population of flue-cured tobacco (N. tabacum cv. Yunyan87) using ethyl methanesulfonate (EMS) to identify eIF4E1-S mutants. M3 plants homozygous for a nonsense mutation in exon 1 of the eIF4E1-S gene demonstrated resistance against PVYMN. These M3 plants were backcrossed to ‘Yunyan87’, and BC4F3 plants were screened using derived cleaved amplified polymorphic sequence (dCAPS) markers. BC4F3 plants showing agronomic traits comparable to the recurrent parent ‘Yunyan87’ and resistance against PVYO, PVYN, and PVYNTN strains were identified. These genotypes would provide useful germplasm for future tobacco improvement and would aid in basic research on PVY resistance in flue-cured tobacco.

In this first contribution to the study of virgin olive oils from the area assigned to the Protected Designation of Origin (PDO) “Aceite de la Alcarria” (Spain), both monovarietal oils obtained under ideal conditions in a pilot plant, as well as blend oils made in the oil mills located in the study area, were characterized. Special interest was focused on the influence of the ripening state of the fruits. The oils from the Castellana variety, the main variety found in the study area, were characterized by a high content of tocopherols, medium oxidative stability and high content in palmitic, palmitoleic and linolenic acids. As the ripening process progresses, the oils lose fruitiness, bitterness, pungency, stability, and some organoleptic defects appear, to the point of lowering the category (from extra virgin to virgin) in some of the Castellana samples. Thus, early collection of olives of this variety is recommended.

The quantitative assessment of antimicrobial use (AMU) in food-producing animals contributes to the provision of essential information for developing relevant and effective policies to reduce use and to control antimicrobial resistance. Information on AMU is available mainly for intensive dairy farming systems and specialized high-yielding breeds. The aim of this study is to investigate AMU in different dairy farming systems by comparing the treatment incidence in mountain farms with specialized high-yield dairy breeds or with dual-purpose breeds raised for milk production to the treatment incidence in lowland farms with specialized high-yield dairy breeds or with dual-purpose breeds raised for milk production. Significant differences were found only between the overall treatment incidence, as well as the treatment incidence of highest-priority critically important antimicrobials for human medicine, in lowland farms with high-yielding breeds and mountain farms with dual-purpose breeds. Mountain farms have a generally lower milk production and smaller herd size than lowland farms, provide cows with access to pasture, and limit concentrates in the diet. These management practices and the use of local/dual-purpose breeds could reduce the risk of production diseases and the consequent need for AMU.
