Published: January 2019

U ovom radu prikazani su rezultati etnobotaničkog istraživanja tradicionalnog korištenja samoniklog jestivog bilja na području općine Kršan, provedenog tijekom 2017. i 2018. godine. Ukupno je dokumentirano 107 biljnih vrsta (od toga 17 kultiviranih vrsta), u prosjeku 26 vrsta po jednom intervjuu. Rezultati ovog istraživanja pokazuju da se najveći broj samoniklih biljaka najčešće koristi kao: sirove salate ili kuhano povrće (37 vrsta), sirovo divlje voće (24 vrste), svakodnevni / ili medicinski čajevi (18 vrsti), začinske biljke (4 vrste), a 7 vrsta ima specifičnu medicinsku uporabu.
Pored najčešće spominjane vrste povrća, popularne šparoge (Asparagus acutifolius L.), zanimljiva je i vrlo česta konzumacija šparogama sličnih biljaka čiji se mladi izdanci jedu sirovi, kuhani ili u mješavini s kokošjim jajima: Ruscus aculeatus L., Clematis vitalba L., Tamus communis L. i Humulus lupulus L. Zabilježena je i hrana korištena u
vrijeme velike gladi (za vrijeme 1. i 2. svjetskog rata), primjerice Quercus ilex L. Posebna karakteristika lokalne gastronomije je kiseljenje mladih izbojaka Ruscus aculeatus L., kao i kiseljenje Portulaca oleraceae L. koje koriste kao salatu / prilog mesnim jelima tijekom zime. Uz spomenute vrste najčešće korišteno povrće je: Foeniculum vulgare L., Urtica dioica L., Taraxacum officinale L., Cichorium inthybus L. i Sonchus oleraceus L. Najčešće korišteno divlje voće je: Rubus ulmifolius L., Juniperus oxycedrus L., Cornus mas L., Morus nigra L., M. alba L. i Sorbus domestica L. Upotreba nekultiviranog
povrća duž Mediteranskog dijela Hrvatske još je uvijek relativno česta,
iako je u opadanju, kao i u cijeloj Europi i na globalnoj razini.
Organizational culture in Public Institutions and its effect over the implementation of Total Quality Management Process- Kosovo Case
Authors: Rexhepi Ilir , Qosja Ermira
Published: January 2019

Total Quality management (TQM) is a philosophy management method, the importance of which continuously has been growing after '90. There is relatively short time since Kosovo Public Institutions are practically doing their activity as a part of an independent Country, and as such day by day they are facing with different management challenges which continuously are becoming more rough and tough towards the EU integration process.

Total Quality Management within Public Institutions, is leaded by the phase of establishment and implementation of Quality management Systems based on ISO 9001. In this process, through a deep empiric study in three Kosovo Public Institutions, we have tried to identify the advantage and disadvantage factors towards the successful implementation of quality management system in time, as a consequence of TQM. Moreover, we were focused on the organizational culture. Analyses over norms, trusts, principals that do characterize the organizational culture of Kosovo Institutions, its crossing with the political context and the Public Administration law will serve to model changes that should be projected in order to successfully implement the TQM. In the function of the disadvantage factor analyses, organizational cultural elements, and the changes model, there will be used a number questionnaires and interviews with relevant people.
Urban heat islands (UHI) mitigation in densely urban city of Tirana, Albania: Materials, energy, comfort
Authors: Dervishi Sokol , Lacaj Eltjona , Vathi Regina
Published: January 2019

Urban Heat Island (UHI) is considered as one of the major problems in the 21st century as a result of urbanization and industrialization of human civilization. The urban structures generate a large amount of heat from solar radiations and other sources (i.e. anthropogenic heat). This situation is even worse in cities with high density and large population and extensive economic activities, Tirana, a densely urbanized city, is seriously facing this problem. In this context, the present paper is a review article aiming to present the actual state of the art on the development and the assessment of potential benefits (i.e. materials with high solar reflectance, urban vegetation) as UHI mitigation strategies for buildings and urban structures in Tirana, Albania. The analysis shows that the limited urban vegetation and inner-city neighborhoods structures are those ones in which the hazard potential of the UHI effect is shown to be the greatest. These neighborhoods have limited open space for tree planting and green area and therefore a lower maximum potential benefit. During the warming of the climate these neighborhoods face the greater consequences due to interactions between the UHI effect and global climate change. The results show that implementations of different strategies of urban heat island (UHI) mitigation can reduce negative impacts of hazards in cities, including overheating due to elevated temperatures, air pollution and associated public health effects. Such strategies also can lower the demand for air-conditioning-related energy production; reduce the effects of urban heat island and ultimately living in a better environment.

Published: January 2019

Automation of water flow at plastering machines is a solution which serves the process of plastering, to adhere international standards. Automation of water flow by taking signals from the condition of the material depending on humidity. So its output is used to influence the increase or decrease of the amount of water flow in the valve. Water flow automation is a system which consists of several components in which the already, develop different processes. To release the feedback we need a sensor which is built by piezoelemnt in which we have the phenomenon of the frequency. With which we have to create a variable signal at the entrance of electronic board . This signal varies depending on the moisture condition to the material of the exit of machine. Electronic board which is part of an intelligent system where we have 6 incoming signals and 4 signals at its output. We have an actuator which depending on the orders it receives from electronic board in valve reacts and works to increase and decrease the amount of water that flows. We have a float 1,0,2 (auto, 0, manual) which serves to orient the system in manual or automatic system. Manual system is realized through one potentiometer, while automatic system is implemented by using the sensor. So it comes to obtaining information on the move again while the system operates automatically.

Authors: Brozovsky Jiri , Bodnarova Lenka , Brozovsky jr Jiri
Published: January 2019

This study examines the factors affecting the results of non-destructive testing of high-strength concrete performed on cubes and on cylinders and examines the processing of calibration relations. Tests were performed with both a type N and a type L Schmidt impact hammer (with a standard impact energy of 2.205 Nm and 0.735 Nm respectively). The assessed factors were internal stress in a specimen and the shape of the impact area. Test specimens were loaded by a force corresponding to the stress in specimen 0%, 10%, 20%, 30%, and 50% from the expected compressive strength. Rebound numbers of the unloaded test specimens were significantly lower than those of the loaded specimens. Therefore, calibration relations and/or correction coefficients processed by measurements of unloaded specimens can be assessed as unsuitable. To process calibration relations, we recommend exerting internal stress in amounts of 15% to 20% of the expected compressive strength of the tested HSC samples. During the determination of the effect of the shape of the test area on the cylindrical test specimen, it was assumed that the rebound numbers on the plane and the round test area would be the same. However, the test results revealed that the rebound numbers in the differently shaped test areas were different. For Schmidt impact hammer type N, the rebound numbers in the round test area were lower by 0.7 units on average, and for Schmidt impact hammer type L, the rebound numbers in the round test area were lower by 1.7 units on average compared to the plane test area rebound numbers.

Operation and physics of photovoltaic solar cells: an overview
Authors: Guerra Noemi , Guevara Marco , Palacios Cesar , Crupi Felice
Published: January 2019

Solar energy is considered the primary source of renewable energy on earth; and among them, solar irradiance has both, the energy potential and the duration sufficient to match mankind future energy needs. Nowadays, despite the significant potential of sunlight for supplying energy, solar power provides only a very small fraction (of about 0.5%) of the global energy demand. In order to increase the worldwide installed PV capacity, solar photovoltaic systems must become more efficient, reliable, cost-competitive and responsive to the current demands of the market. In this context, PV industry in view of the forthcoming adoption of more complex architectures requires the improvement of photovoltaic cells in terms of reducing the related loss mechanism, focusing on the optimization of the process design, as well as, reducing manufacturing complexity and cost. Hence a careful choice of materials, a suitable architecture and geometric distribution, passivation techniques and the adoption of a suitable numerical modeling simulation strategy are mandatory. This work is part of a research activity on some advanced technological solutions aimed at enhancing the conversion efficiency of silicon solar cells. In particular, a detailed study on the main concepts related to the physical mechanisms such as generation and recombination process, movement, the collection of charge carriers, and the simple analytical 1D p-n junction model required to properly understand the behavior of solar cell structures. Additionally, the theoretical efficiency limits and the main loss mechanisms that affect the performance of silicon solar cells are explained.
TCAD 2D numerical simulations for increasing efficiency of AlGaAs – GaAs Solar Cells
Authors: Palacios A. César , Guerra Noemi , Guevara Marco , José López María
Published: January 2019

The performance of solar cells has improved quickly in recent years, the latest research focuses on thin cells, multijunction cells, solar cells of the group III-V compounds, Tandem cells, etc. In the present work, numerical simulations are developed, using SENTAURUS TCAD as a tool, in order to obtain a solar cell model based on Galium Arsenide (GaAs). This solar cell corresponds to the so-called "Thin Films" due to the fact that can make layers thinner than we would have if we work with conventional semiconductors, such as; Silicon or Germanium; thus opening the possibility of placing the cell as a top layer within a tandem solar cell configuration with compounds of group III-V. That is why two types of simulations are performed with respect to the contact of the rear contact; one corresponds to the cell with a lower contact equal to the length of the cell and the other with a small contact of 5 μm. In addition, the cell undergoes an optimization process by modifying the geometry and doping of the layers that comprise it, in order to improve its performance. To achieve this objective, the initial conditions and the appropriate simulation parameters must be determined, which have been selected and corroborated with the literature, allowing us to arrive at coherent results and optimal models of solar cell design through numerical simulations.

Published: January 2019

En Panamá, el atún aleta amarilla de la familia Scombridae, es la principal especie de atún capturada en el país, la obtención de dicha especie se rige por diversas regulaciones. La escombroidosis tiene su origen por el consumo de peces de la familia Scombridae, que contiene alta cantidad de histamina, causando un desequilibrio entre la acumulación de histamina y la capacidad del organismo para degradarla. La histamina se produce por la descarboxilación de la histidina, los efectos de la histamina se ejercen mediante la activación de receptores, de los cuales se han identificado cuatro subtipos (H1, H2, H3, H4), que influyen en el reconocimiento a los síntomas de intoxicación por escombroides, tales como el enrojecimiento, el picor y la distermia, también, acciones sobre el sistema cardiovascular. Nuestro país no cuenta con normas que regulen el contenido de histamina, por lo tanto, se espera que este trabajo influya de manera positiva, dando a conocer a la población panameña este tipo de intoxicación alimentaria, la forma como se produce, su prevención, sus efectos y tratamiento.

Se presentan resultados de simulaciones computacionales basadas en los principios de conservación de masa, cantidad de movimiento y leyes de Maxwell, resueltas simultáneamente con la ayuda del software comercial PHOENICS. El modelo predice las propiedades eléctricas de la columna del arco, los patrones de flujo, contornos de temperatura, flujo de calor y potencial eléctrico, al variar la longitud de arco y la corriente aplicada. Al incrementar la corriente, el jet del arco es más intenso, el arco es más caliente y transfiere más calor a la pieza de trabajo, mientras que al incrementar la longitud del arco la temperatura máxima, la velocidad máxima y el flujo de calor no cambian aunque un arco corto focaliza más el calor que un arco largo.

El objetivo de este proyecto es diseñar un sistema que permita contar frutas mediante el uso de tecnología Arduino y sensor de luz. Para la construcción del sistema completo se utilizaron otros componentes como una pantalla LCD y un potenciómetro. En un principio el sistema está formado de dos partes: el sistema contador y la estructura física que contendrá las frutas. La estructura física diseñada con materiales de PVC y metal, será utilizada para el paso de las frutas por medio de una rampa en donde se hará la lectura mediante el sistema contador. El sistema contador que estará formado por la placa Arduino y el sensor de luz, será el encargado de hacer la lectura de la cantidad de frutas que pasen a través de la rampa. Para tener una visualización de la cantidad de frutas que se va contabilizando, el sistema cuenta con una pantalla LCD, cuyo contraste estará regulado por un potenciómetro para una mejor visualización.
TÜRK BASININDA YOL AYRIMINA BİR ÖRNEK: CAVİD ORAL VE HÜRSES GAZETESİ

Siyaset kurumu ile basın kuruluşları
arasında doğrudan bir ilişki bulunmaktadır. Bilhassa da iktidar partisinin
basınla ilişkisi ayrı bir önem taşımaktadır. Bazen iktidar partisinin, yayın organlarıyla ilişkileri olumlu bir
seyir izlerken, zaman zaman da taraflar arasında bir cepheleşme yaşanabilmekte
ve iktidarla basın karşı karşıya gelebilmektedir. DP zamanında basınla iktidar ilişkisi farklılıklar sundu. Örneğin,
yayın hayatına CHP çizgisinde başlayan ve CHP’li bir siyasetçi olan Cavit Oral’ın
sahip olduğu Hürses gazetesi bu kategoridedir. Gazetenin haberlerinde ve Oral’ın
yazılarında ilk iki yıl görülen DP muhalifi ve CHP destekçisi pozisyon iki
yılın sonunda değişmeye başladı ve Oral’ın DP’ye geçmesiyle daha da belirgin
bir hâl aldı. Böylece, Hürses DP çizgisinde, ama kesinlikle bir resmi yayın
organı gibi değil, bir yayın politikası benimsedi.

Bu çalışmada, örnekleriyle Hürses
gazetesinin haberlerindeki kullanılan dilin değişimi ile Cavit Oral’ın
yazılarında kaleme aldığı ifadelerdeki yaklaşımın farklılığı ortaya konarak,
muhalefetten iktidara geçen bir yayın organındaki bu değişim ortaya konmaya
çalışılarak, iktidar-basın ilişkisinde yaşanan “dönüşümün” fotoğrafı
sunulmaktadır.
DİL DEVRİMİNİN HALKÇILIK BOYUTU

Yeni
Türk devletinin ideallerinden biri, halkın yönetime katılması, kendi yararına
davranabilmesiydi. Gerçekleştirilecek kültür devrimi sayesinde halkın ulaşacağı
kültürel ve entelektüel düzey ile bu ideale ulaşılabilirdi. Halkın devletle ve
aydınlarla yakınlaşması, dilde yapılacak devrimle mümkündü. Bu ihtiyaç, Osmanlı
Devleti’nin son yüzyılında açıkça görülmüştü. Ancak bu gereksinimi gideren hareket,
milli uyanışın gerçekleşmesiydi. Dil devriminin özünde halka doğru gitmek, onun
kolayca okuyup yazmasını kolaylaştırmaktı. Bunun için yalnız yazıda Latin
kökenli yeni Türk alfabesinin kabulü yeterli değildi. Hukukta olduğu gibi
halkın hayatının içindeki her noktada dilin kullanabilir ve anlaşılabilir
olması gerekliydi. Gazi Mustafa Kemal Atatürk, Milli Mücadele’nin başından
itibaren olduğu gibi halk için halkla beraber hareket etmiş; dil konusunda bu
tutumunu sürdürmüştü. Kanun önünde olduğu gibi eşit, ayrımsız, ayrıcalıksız bir
toplum için, hayat içinde fırsat eşitliğinin korunmasında toplum fertlerinin
her birinin diğerinin yazdıklarını kolayca okuyup anlayabilmeleri Türk kültür
devriminin bir gereğiydi. Bu yaklaşım bağlamında dil devriminin halkçı bir
tarafının olduğunu söylemek mümkündür.
TÜRK VE RUS KAYNAKLARI IŞIĞINDA 1989 FERGANA OLAYLARI

Sovyetler Birliği döneminde birçok
halk, özellikle Türk soylular, siyasi baskıya uğrayarak vatanlarından
sürülmüşlerdi. Bugüne kadar vatanına geri dönemeyen Türk topluluklarından biri
de Ahıska Türkleridir. Gürcistan’ın yerli halkı olan Ahıskalılar, ülkenin
güneyindeki Akhiska (Meshetia), Ahaltsike, Adigön, Aspindza ve kısmen Javaheti
(Ahılkelek bölgesi)’nin üç bölgesinde asırlar boyu varlıklarını sürdürmüşlerdi.
1944 yılında, Sovyetler tarafından tarihi anavatanlarından Orta Asya
Cumhuriyetlerine sürgün edilmişler, ancak orada da huzur bulamamışlardı. 1989
yılında Ahıska sakinleri Özbekistan SSC’in Fergana bölgesinde “Fergana Olayları”
olarak bilinen kitlesel çatışmalar sonucunda, toplu bir faciaya maruz bırakıldılar.
Bu olaylar sırasında Ahıska Türkleri büyük zararlar gördüler. Dünya kamuoyu ilk
kez Ahıska Türklerini “Turki Meshetintsı” olarak bu kanlı olaydan sonra tanıdı.  Rus basınında “Fergana Olayları” diye geçen
bu elim olayın ardından, Rus hükümeti Fergana ve yakın bölgelerden Ahıska
Türklerini organize bir şekilde SSCB’nin farklı cumhuriyetlerine gönderdi.
Özbekistan’ın neredeyse tüm bölgelerinde yaşayan Türk nüfusu diğer Sovyet
cumhuriyetlerine göç etmeye mecbur kaldılar. Fergana olaylarına daha yakından
bakıldığında, bilinen “çatışma” kavramının çok ötesinde olduğunu görmekteyiz. Bu
nedenle, çalışmamızda Ahıskalılar başına gelen bu acı olayı, Rus basını ışığında
araştırmaya ve değerlendirmeye çalışacağız.
Economic Evaluation of Biodegradable Plastic Films and Paper Mulches Used in Open-Air Grown Pepper (Capsicum annum L.) Crop

Published: January 2019

Black polyethylene (PE) is the most common mulching material used in horticultural crops in the world but its use represents a very serious environmental problem. Biodegradable films and paper mulches are available alternatives but farmers are reluctant to adopt them because of their high market prices. The aim of this paper is to evaluate the economic profitability of eight biodegradable mulching materials available for open-air pepper production. The economic evaluation is based on a four-year trial located in a semi-arid region of Spain. Three scenarios of PE waste management are examined: (i) absence of residues management, (ii) landfill accumulation, and (iii) total recycling. The inclusion of the costs of waste management and recycling under the current Spanish legislation only reduced the final net margin by 0.2%. The results show that an increase in subsidy rates of up to 50.1% on the market price would allow all biodegradable films to be economic alternatives to PE. The study supports the mandatory measures for the farmers to assume the costs of waste management and recycling. Despite savings in field conditioning costs, high market prices of biodegradable materials and papers are not compensated by the current level of subsidies, hampering their adoption in the fields.
Long Term Stable Δ-Σ NDIR Technique Based on Temperature Compensation
Authors: Shen Chih-Hsiung , Yeah Jun-Hong
Published: January 2019

For a fast and long term stable Non Dispersive Infrared (NDIR) technology of gas concentration measurement, the temperature compensation is required. A novel proposed Δ-Σ NDIR system was investigated and built with a closed-loop feedback system to stabilize the signal readings without temperature drift. The modulation of the infrared heater gives a corresponding signal of gas concentration based on our proposed Δ-Σ conversion algorithm that was affected by the drift of temperatures for the infrared sensor. For our study, a new temperature compensation model was built and verified that formulates the relationship between gas concentration and temperature of sensor. The results show that our proposed Δ-Σ can measure efficiently with half of the startup time than our previous design and maintain long term stability.

Published: January 2019

Tensioning is an important process for producing prestressed concrete beams and directly affects bridge performance and driving safety. Active sensing and management of tensioning process data can improve the efficiency of quality monitoring and level of prestressed concrete beams. To realize remote collection and quality monitoring of tensioning process data, a framework for data sensing and processing of tensioning system based on the Internet of Things (IoT) is proposed in this study. Firstly, we investigate the technical framework and techniques of the system and designs a work flow of sensing, transport, and application service layers. The architecture of the tensioning system is presented. Then we propose a data acquisition and preprocessing method for the sensing layer, put forwards the data-pushing mechanism of the transport layer, and designs the function and work flow of the application service layer. After that, .NET platform and Android Studio are used to implement the tensioning system based on Browser/Server (B/S) architecture and mobile terminals. Finally, the case results of the system in seven precast beam fields in the Hubei section of Zhengzhou–Wanzhou high-speed Railway are given, which show that the developed system realizes collection, active pushing, and remote monitoring of tensioning process data.

Published: January 2019

Aiming at solving the multiple fault diagnosis problem as well as the sequence of all the potential multiple faults simultaneously, a new multiple fault diagnosis method based on the dependency model method as well as the knowledge in test results and the prior probability of each fault type is proposed. Firstly, the dependency model of the system can be built and used to formulate the fault-test dependency matrix. Then, the dependency matrix is simplified according to the knowledge in the test results of the system. After that, the logic ‘OR’ operation is performed on the feature vectors of the fault status in the simplified dependency matrix to formulate the multiple fault dependency matrix. Finally, fault diagnosis is based on the multiple fault dependency matrix and the ranking of each fault type calculated basing on the prior probability of each fault status. An illustrative numerical example and a case study are presented to verify the effectiveness and superiority of the proposed method.
