Smart Home Assistant for Ambient Assisted Living of Elderly People with Dementia
No full textIt is the nature of life that with advancing age human brain cells are damaged and brain functions degrade, which is manifested by memory loss, lack of concentration, reduced judgement abilities as well as speaking problems and even noticeable changes in personality and behavior. When a number of these symptoms collectively detected in a person, he usually diagnosed with dementia. These people have problems in managing their daily activities and shortly become unable to live by themselves. Ways to prolong the independent life of elderly people have drawn the attention of a large scientific community. In this paper, we present an integrated system design that allows collection, recording and transmission through a cloud application of the data from different sensors placed in a house of a person having dementia. The concept of this work is a part of the so-called Internet of Things (IoT) where information from smart things around us can be evaluated and transmitted over the internet
Modelling and experimental performance analysis of solar assisted ground source heat pump system
No full textIn this study, slinky (the slinky-loop configuration is also known as the coiled loop or spiral loop of flexible plastic pipe)type ground heat exchanger (GHE) was established for a solar-assisted ground source heat pump system. System modelling is performed with the data obtained from the experiment. Artificial neural network (ANN) and adaptive neuro-fuzzy inference system (ANFIS) are used in modelling. The slinky pipes have been laid horizontally and vertically in a ditch. The system coefficient of performance (COPsys) and the heat pump coefficient of performance (COPhp) have been calculated as 2.88 and 3.55, respectively, at horizontal slinky-type GHE, while COPsys and COPhp were calculated as 2.34 and 2.91, respectively, at vertical slinky-type GHE. The obtained results showed that the ANFIS is more successful than that of ANN for forecasting performance of a solar ground source heat pump system
Survey of wild food plants for human consumption in Bingöl (Turkey)
No full textThis study focused on the wild plants traditionally used for human consumption in Bingöl and its aim is to present data about the folk botanical knowledge and to give about their development in relation to plant resources and traditionally food culture. The information about the use of wild edible plants was collected from 6 different open-air-markets and 13 villages in the city during two-year period (2012-2013), through unstructured interviews. In this study, a total of 61 wild food plant taxa belonging to 25 families were established and also plant parts used, ethnographic data related to vernacular names, traditional use were recorded. Family Rosaceae is represented by the highest number of taxa (9), followed by Lamiaceae (8), Astaraceae (7), Apiaceae (6), Fabaceae (4) and Polygonaceae (3). The study showed that the plants used are either eaten raw, cooked by boiling in water, frying in oil or baked to be served as dishes such as stew, salad as hot drink. During this ethnobotanical research, it was verified that wild edible plants play an important role in diet in Bingöl. Furthermore, during our study Heracleum pastinacifolium C. Koch, Origanum acutidens (Hand.-Mazz.). Letsw, Prunus kurdica Fenzl ex Fritsch, Quercus petraea subsp. pinnatiloba (K. Koch) Menitsky has been recorded as endemic wild food plant taxa from Bingöl

Materyal ve Metot: Bu çalışma Temmuz-Ağustos 2014 tarihlerinde Boztepe Recai Kutan Baraj Gölü’nden farklı göz açıklıklarına sahip tam ve yarım boy olmak üzere 0,50 donam faktörüne göre donatılmış monofilament sade ağlar kullanılarak yakalanmışlardır. Yakalanan C. umbla bireyleri içi buz kalıpları ile doldurulmuş kapalı taşıma tankları ile Elazığ Su Ürünleri Araştırma Enstitüsü Müdürlüğü laboratuvarına getirilmiştir. Balıkların total boyları (TB) ölçüm tahtasında ±1 mm ve ağırlıkları (A) ±1 g hassasiyetle ölçülüp tartılmıştır. Balıkların eşeylerini belirlemek amacıyla karınları açılarak makroskobik olarak incelenmiş ve cinsiyet ayrımları yapılmıştır. Balıkların sağ ve sol sagittal otolitleri ince uçlu pens yardımıyla çıkarılarak petr kaplarına bırakılmıştır üzerlerinde bulunan dokular iyice temizlendikten sonra kilitli poşetlerde muhafaza edilmişlerdir. Otolitlerin ağırlıkları (OA) Bel Engineering marka hassas terazide ± 0,0001 g hassasiyetle tartılmıştır. Otolitlerin boyutları ise bilgisayar destekli Olympus BX53 marka mikroskop yardımıyla Olympus DP25 Analysis LS Research programı kullanılarak 0,001 mm hassasiyette iki eksen üzerinde ölçülmüştür.
Bulgular ve Tartışma: Malatya Boztepe Recai Kutan Baraj Gölü’nde yaşayan Capoeta umbla (Heckel, 1843) popülasyonuna ait toplam 99 örnekte sagittal otolit büyüklüğü (uzunluk, genişlik ve ağırlık) ile balık boyu (total boy) arasındaki ilişkiler incelendi. Total boy ile otolit boyu arasındaki ilişki y=0,0556x+1,2509 (R2=0,7785), total boy ile otolit genişliği arasındaki ilişki y=0,0399x+0,9683 (R2=0,6708) ve total boy ile otolit ağırlığı arasındaki ilişki y=0,0002x+0,0013 (R2=0,6663) olarak tespit edilmiştir. Yapılan literatür taramasından elde edilen bazı balık türlerindeki balık boyu ile otolit biyometrisi üzerine yapılan çalışmalardan elde edilen verilen ile bu çalışmadan elde edilen veriler karşılaştırıldığında büyük oranda birbirleri ile uyumlu oldukları görülmüştür. Malatya ili Boztepe Recai Kutan Baraj Gölü’nde yaşayan Capoeta umbla balığının balık boyu ve otolit biyometrisi ilişkisi üzerine gerçekleştirdiğimiz bu çalışma bölge hakkında bir fikir edinmemize ve otolit biyometrisi çalışmalarına katkı sağlayacağı düşünülmektedir
Some population parameters of alburnus mossulensis (Heckel, 1843) in Boztepe Recai Kutan Dam Lake (Malatya)
No full textIntroduction: The aim of this study is determine some biological properties of Alburnus mossulensis population and this is first study in the Boztepe Recai Kutan Dam Lake.
Material and Methods: Fish samples were caught from Boztepe Recai Kutan Dam Lake between February-March-April 2014. The fish samples were collected using the gill nets with mesh sizes between 20 and 50 mm and each net was 50 m in length. Total length and weight of the each fish sample were measured and their ages were determined from the scales. To determine sex of fishes were investigated gonads by opened its abdomen. Condition factor was calculated from CF= (W*100)/L3 equation. The length-weight relationship was determined with Le Cren’s W= a*Lb equation and the age-length relationship was determined with the von Bertalanffy’s Lt =L∞*(1-e -K*(t –t 0 ) ) equation.
Results: A total of 84 A. mossulensis samples (35 males and 49 females) were investigated and age distribution of the population were determined between I. and IV. age groups. The mean total length values were determined between 10.37-18.59 cm in males; between 10.64-16.88 cm in females, and the mean weight values were determined between 20.77- 60.15 g in males; between 16.08-60.50 g in females. The equation of total length-weight relationship was found as W= 0.155TL2.576 (r= 0.92) for all individuals. Fish age-total length relationship was found as Lt= 24.82*(1-e -0.216*(t+0.06)) for all individuals. The mean condition factor values were determined between 1.39-1.57 in males; between 1.42-1.36 in females.
Discussion: Age distributions, “b” values, condition factor values and VBG parameters calculated in this study were different from other studies. These differences may result from differences of study areas, catching methods, study times and ecological conditions
Comparison of effective lifelong learning levels of pre-service teachers In terms of various variables
