Analysis of hydrogen enriched treble biofuel blended with diesel for performance, emission and combustion characteristics on CI engine
Authors: Md. Fakhruddin H.N. , Ali Mohammed Yousuf , Hussain M. Manzoor
Published: March 2018

The need of the hour is to look forward to alternative fuels to swipe out the dependence on fossil fuels, as biofuels from various feedstocks are being experimented worldwide. However, it is difficult to implement biodiesel from a single feedstock to replace theexisting fossil fuels. It is reliable to obtain biodiesel from local feedstock and to make multiple biodiesel mixtures blended with diesel. The present work relies more on biofuels and acts as a step towards fossil fuel-free engine or at least to snatch the lion’s share ofthe fossil fuels. In this contest, the experiment was carried out by using treble biofuels i.e., WCOBD + PSBD + Bio-hydrogen at different injection pressures (i.e., 200bar, 225bar and 250bar) and compared them with a similar engine that utilised fossil fuel as the stand-alone fuel. The mixture ratios were B10, B20 and B30 and the enrichment of hydrogen was done at 4lpm, 6lpm and 8lpm. The results showed that the brake thermal efficiency of dual biofuel blended diesel decreased as compared to that of the base fuel and increased with hydrogen enriched biodiesel. Hence, the brake specific energy consumption decreased for the hydrogen enriched fuel and the exhaust emissions of CO and CO2 were reduced, however, NOx showed an increasing trend as usual.
Energy saving technologies for urban bus transport
Authors: Hnatov A. , Arhun Shch.
Published: March 2018

Reduction of non-renewable sources of energy and the ecological state of metropolises have become the cause of the search for optimal solutions for introduction of energyefficient and environmentally friendly technologies for urban bus transport, which is thepurpose of this work. A review of environmentally friendly buses has shown that electric buses (electrobuses) are the most perspective. However, rapid replacement of all the buses with electrobuses is impossible because of their high cost. A comparative analysis of theoperating costs of different types of buses of the same destination and class has been carried out in order to choose the optimal variant. Thus, one route of 4.23 km in length was chosen in Kharkiv (Ukraine). Experimental and calculated data showed that aminibus converted into an electrobus is the most acceptable means for urban passenger transportation. Ultra-capacitors are suggested as an energy source. The conceptualdiagram of the model of such a bus  is presented and the technical requirements for itscomponents are determined. The data and proposals are useful for Ukraine and for countries with low economic development that cannot quickly replace old diesel buseswith new, environmentally friendly, electrobuses. The results of this work are the basisfor further research and development.

Authors: Ahmed Shakil , Ahsan Ashraful , Hasan Mahbub
Published: March 2018

Composite materials are materials made from two or more constituent materials with significantly different physical or chemical properties, that when combined will produce a material with characteristics difference from the individual components. Hybridcomposite means a special type of composite which contains more than one fibre material as a reinforcing filler. Multiple fibres reinforced composite gives a wide variety of mechanical properties with respect to single fibre containing composite. The eco-friendlynature, as well as processing advantage, light-weight and low cost, have enhanced attraction and interest of natural fibre reinforced composites. The objective of the present research is to study the mechanical properties of jute-coir fibre reinforced hybridpolyethylene composites. Composites were manufactured by using a hot press machine at three levels of fibre loading (5 wt.%, 10 wt.%, and 15 wt. %). Tensile, flexural, impact, and hardness tests were conducted for mechanical characterisation. Water absorption and scanning electron microscopic analysis were carried out as part of physical evaluation. Tensile test of composite showed a decreased tensile strength trend and increased Young’s modulus trend with the increase in fibre content. During flexural, impact, andhardness tests, the flexural strength, flexural modulus, impact strength, and hardness were increased with increase in fibre loading. Water absorption also increased with increase in fibre loading. Scanning electron microscopic analysis showed the strongest adhesionbetween fibre and matrix in the 15% fibre reinforced composite. Based on the fibre loading used in this study, 15 % fibre reinforced composite resulted in the best set of mechanical properties.
Analysis of a diesel engine fuelled with jojoba blend and coir pith producer gas
Authors: Nayak S. K. , Mishra P. C.
Published: March 2018

The emission characteristics of Jojoba biodiesel and preheated Jojoba oil blends along with producer gas from coir pith, in a dual fuel diesel engine under two different experimental conditions, were measured. The present experiment the emission characteristics of a diesel engine that was operated in dual fuel mode. The producer gas is the main fuel and jojoba biodiesel blends and jojoba preheated oil are the injected fuel. Firstly, diesel, biodiesel blends, and preheated oils with coir pith generated producer gas were examined in both individual and dual fuel mode at a constant gas flow rate of 21.69 kg/hour at various loading conditions. Secondly, the same test fuels were taken at constant load and different gas flow rates at 10 KW in dual mode. An engine test analysis was carried out at varying load conditions (0 kW, 2 kW, 4 kW, 6 kW, 8 kW, and 10 kW) by keeping the producer gas flow rate constant i.e. at 21.69 kg/h. All emissions were seen to be on the higher side for preheated oil as compared to biodiesel producer gas dual fuel mode at all load conditions. The nitrogen oxides and smoke opacity were reduced, whereas carbon dioxide, carbon monoxide and hydrocarbon were increased for all test fuels in dual fuel operation as compared to a single style at different loading conditions. All fuel blends showed better emissions than that of diesel in both ways. Utilising jojoba biodiesel producer gas dual fuel mode, emission parameters like CO2, smoke and NOx are higher as compared to diesel producer gas operation. At optimal load condition, smoke emission for preheated oil producer gas dual fuel operation is 62% higher than the diesel producer gas mode. Diesel savings for diesel producer gas operation fetch up to 83% when correlated with B20 biodiesel producer gas blend up to 81.6%, at optimal load condition. Hence, it might be concluded that jojoba biodiesel producer gas up to 20% blend, i.e. B20, can be utilised as potential fuel for presenting diesel engine without much engine modification. Nevertheless, in the second case, with an increase in gas flow rate, all blended fuels showed better emissions with respect to diesel. The current paper also recommends further investigation to improve fuel properties and in-cylindercombustion phenomena of jojoba biodiesel before its usage in a dual fuel operated diesel engine.

Authors: Al-Dhahebi Adel Mohammed , Junoh Ahmad Kadri , Mohamed Zamri , Wan Muhamad Wan Zuki Azman
Published: March 2018

This paper proposes a Genetic Algorithm (GA) to optimise vehicles’ interior noise and vibration caused by powertrain, tire-road surface interaction and type of car. Toward this end, an experimental design was carried out to obtain the noise and vibration data of threelocal compact-sized cars at stationary and running conditions and varying engine speeds. The acquired data were analysed to obtain sound quality parameters such as loudness and sharpness, sound pressure level and vibration exposures in the interior cabin. Besides that, a K-means clustering algorithm was utilised to cluster the noise and vibration to determine the comfort level in the vehicle’s interior cabin. The overall findings indicate that the comfort level is influenced by the types of road surface, powertrain and vehicle design. The results also indicate that the proposed GA approach is reliable and can be utilised by automotive researchers to identify the optimal Noise, Vibration and Harshness (NVH) values for vehicle refinement and noise control.

Published: March 2018

This paper presents a simulation of the potential cooling effect that can be harvested from the Liquefied Petroleum Gas (LPG) phase change process on the fuel line before being supplied to the combustion chamber. The composition of LPG used was obtained fromthe average test result of the samples taken periodically in the fuel line with a special gas syringe which were then injected into Gas Chromatography-Mass Spectrometry (GCMS). Effect of fluctuations of LPG composition was also analysed on the energy deliveryto the combustion chamber. Furthermore, simulation results showed that the potential cooling that may be harvested from the LPG fuel system on a 2000 cm3 engine was 1.4 kW in the eco-driving mode to be used as a cabin cooler. For a small passenger car thathas a cooling load of 3.5 kW, this means the cooling effect from the fuel system is capable of contributing 40% to the cooling load. In conclusion, this potential is very promising and can be applied to countries that not do have the winter experience.

Authors: Yüksel Serhat
Published: March 2018

The purpose of this study is to identify the effects of research and development expenses on export and economic growth. Within this scope, annual data of 28 European Union member countries for the periods between 1996 and 2014 was taken into the consideration. Additionally, Dumitrescu Hurlin panel causality analysis was used in this study to achieve this objective. First of all, Im, Pesaran and Shin and Levin, Lin & Chu panel unit root tests were used to understand whether the variables are stationary or not. As a result of these tests, it was defined that the variable of economic growth is stationary whereas other two variables (export and R&D) are not. According to the results of Dumitrescu Hurlin causality analysis, it was determined that there is not a significant relationship between economic growth and R&D. On the other hand, it was concluded that there is a causality relationship from export to R&D expenses. This situation shows that EU member countries, which have higher export amount, give more importance to R&D in order to improve themselves.
The Determinants of Individual Taxpayers’ Tax Compliance Behaviour in Peninsular Malaysia
Authors: Kiow Tan Swee , Salleh Mohd Fuad Mohd , Kassim Aza Azlina Bt Md
Published: March 2018

The findings from this review suggested that tax compliance behaviour of individual taxpayers is influenced by ethical perception of individual taxpayers and their ethical perception is affected by public governance and transparency in government operations. Ethical perception plays an important role for individual taxpayers to report their income correctly. Ethical perception varies from an individual to another, which influenced by changes in their surroundings and their experiences when interact with government. Perceptions of how taxpayers’ money is being utilised, benefits they derived from government or others evade to pay tax are considered as possible factors influencing their compliance behaviour. Taxpayers will be more compliance if government use tax monies wisely or when taxpayers get benefits for the taxes paid in terms of public goods and social amenities that they prefer. Transparent surroundings will enhance taxpayers’ confidence in public bodies. Taxpayers are concerned on transparency in public procurement as lack of transparency may cause corruption and reduces public sector efficiency. In contrast, scholars argued that greater degree of transparency could lead to less trust as it will be easier for taxpayers to audit government and they might blame government for small mistakes.

Published: March 2018

The main purpose of this study is to evaluate the causality relationship between energy consumption and economic growth for developed countries. Within this context, annual data of 22 developed countries was examined by using Dumitrescu Hurlin panel causality analysis. As a result, it was determined that that there is a bidirectional relationship between energy consumption and economic improvement for developed countries. This condition provides two different results. Firstly, energy consumption has an influence on economic development for these countries. While considering this result, it can be said that any limitation in energy consumption will restrict economic growth. Moreover, it was also concluded that level of economic growth is the main reason of energy consumption for developed countries. In other words, developed countries tend to have more energy consumption when their economies are growing.

Published: March 2018

This study is set to examine the relationship between working capital management policy and profitability of quoted food and beverages companies in Nigeria. The population comprises a sample of ten (10) food and beverage companies quoted on the Nigerian Stock Exchange. The study used secondary data for a period of ten (10) years (2005-2014) and was analyzed using descriptive and inferential statistics with the aid of Stata version 13. Two research hypotheses were formulated and tested. It was found that, there is no significant relationship between receivable collection period (RCP) policy and profitability of quoted food and beverage companies in Nigeria. However, it was recommended that the management should identify the level of inventory which allows for uninterrupted production but reduces the investment in raw materials and minimizes reordering cost and hence increases profitability. The management should reduce their RCP from 53 days on the average to at most 30 days by instituting adequate control and flexible credit policy.
Comparison analysis of Baso Cellular Carcinoma and Spino Cellular Carcinoma - Protein Kinase D1, Wnt/β-catenin and Epithelial to Mesenchimal Transition (markers)
Authors: Ivanova Petya V. , Maneva Ana I.
Published: March 2018

Understanding cancer biology is crucial to the successful diagnosis and application of  personalized therapies. Skin carcinogenesis is a multi-step process. The first step is the development of potentially malignant disorders (PMDs) known as leukoplakia, erytroplakia, lichen planus, probably trough mutation in the proteins regulated cell cycle (p16INK4A, p21Waf1/Cip1/Sdi1, p27 kip1, Cyclin D1) and, second in p53 (TP53), Ras, hTert, EGFR, will reverse benign phenotype of late precancer lesions (PMDs) into benign cancer lesion. Third mutation probably in PI3K, PKD1 or E-cadherin, will increase malignant potential of SCCs, activating EMTransition, invasion and metastasis, e.g. aggressive phenotype. In BCC mutations of p53 are known to be late events (UV signature), whereas silencing of 14-3-3 takes place early in tumor progression, concomitant with increased activity of Snail. Early increased expression of PKD1 and down-regulation of c-myc mRNA are also events in pathogenesis of BCC. There is no data for detected mutations in PKD1 gene in both cancers, although the kinases is with high expression in BCC and lack of expression in SCC. There is no data concerning PKD1 expression in the PMDs leading to SCCs, nor to BCCs, such data were recently published concerning PKD1 expression in pancreatic oncogenesis. Curently adequate question is whether lack of PKD1 expression in SCCs, despite its PMDs origin, is a consequence of its spinous layer origin, or is a consequense of PKD1 gene mutations (downregulation). Identification of mutations as markers for early malignant transformation could be useful for early diagnosis and treatment of skin head and neck cancers.
Jamesonian Interpretation of Post Postmodernism: David Foster Wallace’s Infinite Jest and The Pale King
Authors: Goudarzi Abdolreza
Published: March 2018

Postmodernism and Post Postmodernism have dominated culture and literature since the late-20th-century and in basic features, they contradict each other. In Postmodernism, or the period known as the late capitalism by Fredric Jameson, some sort of fragmentation rather than totality is intended to control again the life of the people through the same media in a process known as consumerism; However, in Post Postmodernism, a new sort of humanism seems to be emerging by David Foster Wallace who shows not only the pain but also the cure. In fact, the subjectivity of man is given a niche, and also he is given a voice to express his thought, like the opportunity he has gained in the social networks like Facebook and Telegram, having made it paradoxically possible for him to have a sort of sharing among the fragmented individuals. In fact, every fragmented man can be an active agent, communicator, and finally a producer to bring meaning and discipline back to the life rather than a sole passive watcher, reader, and one way communicator controlled by the system as presented in the modern and postmodern works. Focusing on David Foster Wallace’s (1962-2008) novels—Infinite Jest (1996) and The Pale King  (2011), the aim of this article is to study these three novels through the critical gates of the philosopher, Fredric Jameson to open up the concepts of Post Postmodernism.

Published: March 2018

Glycemic Index (GI) is a measure of the effect foods have on blood glucose (i.e., blood sugar). In this study, it was aimed to find out the GI of highbush cranberry juice (HCJ) in four forms of use (juice with no added sugar and juice sweetened with corn syrup, sucrose or honey) based on data from a total of 20 healthy volunteers.

After not eating for 12 hours and consuming the test foods and the reference food, the participants were subject to blood drawing by automatic lancet, 15, 30, 45, 60, 90, and 120 minutes into the application. GI values of HCJ samples were found by calculating incremental areas for each individual. GI of HCJ with no added sugar had the lowest value (40.95), followed by that of the sucrose added HCJ (42.75). GIs of HCJ with corn syrup and honey were found to be similar, 54.16 and 56.98, respectively. Moreover, those with no added sugar and those with sucrose and corn syrup fell into the low GI category, while the GI of HCJ with honey fell into the medium GI category. In conclusion, it is suggested that consuming HCJ with low GI values might be a healthier choice for individuals with chronical illnesses.

Keywords: Glycemic index, highbush cranberry juice, sucrose, corn syrup, honey.

Why do Democracies Experience Antisystem Movements: Statistical Analysis from Interwar Europe (1919-1939)
Authors: Lika Idlir
Published: March 2018

Why do some democracies experience antisystem movements whereas others do not? Enlisting novel cross-national data from Varieties of Democracy (V-Dem) project and empirically focusing on interwar Europe, this article statistically tests widely-accepted theoretical claims in the literature on political authoritarianism. Logistic regression models applied on 22 interwar European democracies reveal that economic crises are a major cause behind antisystem movement emergence whereas the evidence for attributing causal effect to party institutionalization is not strong enough. Furthermore, the results show that in polarized party systems, the support of center-left/right parties is a crucial factor that leads to antisystem movement emergence in democratic polities.

Published: March 2018

Abstract:

Cerebral amyloid angiopathy (CAA) is most commonly recognized by β-amyloid deposition in the small and medium sized vessels of the brain. The 71-year-old female presented with a sudden onset of vertigo and headache. By native computer tomography (CT) examination we found cerebral atrophy and the sign of chronic vascular injury. The complaints of the patient worsened, thus magnetic resonance imaging (MRI) was performed. The MRI scan revealed a bleeding transformation of an ischemic lesion in the right occipital region. On the susceptibility weighted scans we could observe old microbleedings, thus we suspected CAA. The patient later re-presented at the clinic with a sudden onset of right sided hemiplegia. We performed a native CT scan which identified cerebral hemorrhage in atypical position confirming our diagnosis. CAA has many radiological presentations. The most important is the lobar cerebral hemorrhage. On the susceptibility weighted MRI scans, we could identify the microbleeds and the superficial siderosis by the deposition of the hemosiderin. The subarachnoid hemorrhage is a sign of bad outcome. In the white matter, we could detect the change of the related inflammation and the leukoaraiosis. Further, two not specific abnormalities can be important as well, such as extended ischemic lesions and perivascular space dilatation. CAA has various appearances on MRI. Repeated vascular events and dementia in old age patients draw attention to its presence. The correct diagnosis can be made with the right interpretation of the patient’s complaints in combination with the radiological abnormalities. Orv Hetil. 2018; 159(11): 439–444.

Abstract:

Introduction and aim: To report the clinical outcomes of second breast-conserving therapy with perioperative interstitial radiotherapy for the treatment of ipsilateral breast tumor recurrences. Method: Between 1999 and 2015, 33 patients, presenting with an ipsilateral breast tumor recurrence after previous breast conserving therapy, were salvaged by re-excision and perioperative high-dose-rate interstitial brachytherapy. A median of 8 (range: 4–24) catheters were implanted into the tumor bed intraoperatively. A total dose of 22 Gy in 5 fractions of 4.4 Gy was delivered to the tumor bed with a margin of 1–2 cm, on 3 consecutive days. The adjuvant systemic treatments consisted of hormonal therapy for 24 patients (73%) and chemotherapy for 6 patients (18%). The survival results were estimated by the Kaplan–Meier method. Late side effects and cosmetic results were also registered. Results: The median follow-up time following the second breast conserving therapy was 61 months (range: 26–189 months). During the follow-up, 4 patients (12.1%) developed second local recurrence. The five-year actuarial rates of the second local, regional and distant recurrence were 6.3%, 6.1%, and 14.9%, respectively. The five-year probabilities of disease-free, cancer-specific and overall survival were 76.2%, 92.4%, and 89.2%, respectively. Four (12%), 19 (58%), 4 (12%) and 6 (18%) patients had excellent, good, fair and poor cosmetic results, respectively. Grade 2 and 3 fibrosis developed in 9 (27%) and 1 (3%) patients. Asymptomatic fat necrosis was detected in 7 (21%) women. Conclusion: Second breast conserving therapy with perioperative high-dose-rate interstitial brachytherapy is a safe and feasible option for the management of ipsilateral breast tumor recurrences. Interstitial brachytherapy may decrease the risk of second local relapse with acceptable cosmetic results and low rate of late side effects. Hence, in selected cases it can provide a feasible alternative to salvage mastectomy. Orv Hetil. 2018; 159(11): 430–438.

Abstract:

This study summarizes the results of the author’s PhD thesis presenting the research process and the most important findings regarding the situation of Transylvanian healthcare. Our data are based on the knowledge and compliance of pediatric patients’ rights as they are seen by healthcare specialists, parents and children. A number of 751 persons were involved in the research: 200 healthcare specialists, 200 parents, 200 children aged from 7 to 17 years who have been experiencing health services at least three times over the past year and a control group of 151 children who did not have this kind of experience. Based on our data, it was possible to highlight the major problems encountered in children’s healthcare. We found that children are treated by obsolete principles of medical practice despite the fact that the rights of pediatric patients are well known to doctors. Neither the parents nor the children themselves are sufficiently aware of their rights. Healthcare professionals are not prepared to overcome communication difficulties due to the age-specific characteristics of children, so the fundamental rights of children are just partially enforced: children are usually heard, but not properly informed, their medical decisions are usually not taken into account violating the right to self-determination. The chances to access adequate health services are lower for vulnerable children living in poverty. Orv Hetil. 2018; 159(11): 423–429.

Abstract:

The aim of the present review is to provide an up-to-date picture of what we know about the connection between odontogenic foci and non-oral diseases. After a brief historical summary, we give an overview on how the odontogenic focus causes disease in distant areas of the body in general, and then we start the discussion of the particular conditions, such as cardiovascular diseases, pneumonia, diabetes mellitus, metabolic syndrome, rheumatoid arthritis and adverse pregnancy outcomes. The review is centered around the two main odontogenic foci: periodontitis and periapical periodontitis, the latter being a widely recognized but rarely discussed oral focus. Finally, we offer a few considerations that the practicing dentist may find useful when dealing with odontogenic foci. Orv Hetil. 2018; 159(11): 415–422.

Abstract Introduction: Hypertension (HT) and diabetes mellitus (DM) lead to functional and structural changes in target organs such as the kidneys, characterizing the need for preventive actions to avoid Chronic Kidney Disease (CKD). Objective: To verify cardiologists’ and endocrinologists’ knowledge, indications and practices regarding prevention of CKD in patients with HT and DM. Methods: A cross-sectional study with 14 cardiologists and 5 endocrinologists applying a questionnaire about the conduct of these professionals regarding the prevention of CKD in hypertensive and diabetic patients. Results: One hundred percent of the cardiologists and endocrinologists did not request specific tests for CKD screening (albuminuria and glomerular filtration rate (GFR), although 92.9% of the cardiologists and 60.0% of the endocrinologists report referring hypertensive and diabetic patients with impaired renal function to nephrologists. One hundred percent of the interviewees recognize the importance of physical exercise for their patients; however, only 68.6% of cardiologists and 60% of endocrinologists indicated a physiotherapist and/or physical trainer to implement these exercises. Conclusion: The professionals evaluated in this study do not request microalbuminuria and GFR examinations for hypertensive and diabetic patients as a follow-up routine, despite having found cases of renal function impairment in these patients; in contrast to what is proposed in the guidelines for hypertension and diabetes mellitus. They recognize the importance of physical exercise and report indicating their patients to a physiotherapist and/or physical trainer. We suggest continuing the study in order to ascertain the reasons for their not complying with the respective guidelines.
Seismic soil resistance for caisson design in sand
Authors: Biswas Shibayan , Choudhury Deepankar
Published: March 2018

The exact solution of the passive resistance acting on a caisson foundation due to earthquake-induced loading is important for the seismic design of caissons. In this study, the three-dimensional soil–caisson interaction was taken into account in the determination of the ultimate soil resistance by considering the idealised passive wedge developed in front of a rectangular caisson in sand. A simplified analytical formulation of the seismic passive earth pressure coefficient and its distribution along the wedge height was developed by using the limit equilibrium method and a pseudo-static approach. For the same dataset of input parameters, the seismic passive earth pressure coefficient with a horizontal seismic acceleration coefficient value of 0·2 was approximately 62·7% lower than that for a static condition. The present study emphasises the requirement of correct estimation of the mobilised soil–soil interface friction angle and the height of the passive wedge in order to determine soil resistance. Parametric studies were also carried out to understand the effects of horizontal and vertical seismic acceleration coefficients and the soil–soil interface friction angles. The results of the study compare well with the available experimental data. The solutions proposed should be useful for the seismic design of caissons.

Manisa Alaşehir Ovasında 2016 yılında, sofralık
çekirdeksiz üzüm çeşidi kullanılarak yapılan bu araştırmada, damla sulama
sistemi ile uygulanan tam ve kısıntılı sulama programlarının yaş üzüm verimi ve
kalitesi üzerine etkileri incelenmiştir. Deneme, tesadüf blokları deneme
desenine göre üç tekerrürlü olarak kurulmuştur. Denemede iki farklı bitki
gelişme dönemi (sürme-çiçeklenme dönemi; çiçeklenme-ben düşme dönemi) dikkate
alınarak 8 farklı sulama konusu incelenmiştir. Etkili kök bölgesindeki (0-90
cm) nem açığı dikkate alınarak sulama konuları oluşturulmuştur. Çalışmanın
sonucunda, farklı sulama konularının, yaş üzüm verimi ve kaliteleri üzerinde
p<0.01 düzeyinde önemli olduğu belirlenmiştir. En yüksek verim değeri gelişme
dönemi boyunca, tam sulama suyu uygulanan S1 konusundan
3960 kg da-1 olarak elde edilmiştir. Sulama konularına
toplamda 13 sulama uygulaması yapılmıştır. En yüksek verimin elde edildiği S1
konusuna toplam 554.8 mm sulama suyu uygulanmış ve mevsimlik bitki su tüketimi
616.2 mm olarak belirlenmiştir. Sürme-çiçeklenme dönemi için verim tepki
etmeni (ky) 1.21 olarak belirlenirken, çiçeklenme-ben düşme dönemi için 0.85
olarak belirlenmiştir. Mevsimlik ky ise 1.04 olarak tespit edilmiştir. Su
kullanım randımanı (WUE) değerlerinin 5.91-10.68 kg m-3,
sulama suyu kullanım randımanı (IWUE) değerlerinin ise 6.51-9.72 kg m-3
arasında değiştiği görülmüştür. Sonuç olarak, yüksek yaş üzüm verimi ve
kaliteli meyve elde etmek için yetişme mevsimi boyunca sulama suyu ihtiyacının
tam karşılanması (S1 konusu) gerektiği, eğer bölgede su kaynağı kısıtlı
ise bu koşulda da sadece %25 düzeyinde su kısıntısı uygulanan S2
konusunun uygun olacağı sonucuna varılmıştır.
