    Moisture Sorption Isotherm Characteristics of Peppers
    (Elsevier Science Ltd, 2001) Kaymak-Ertekin,F.; Sultanoglu,M.
    Moisture sorption isotherms of green and red peppers were determined at three different temperatures (30 °C, 45 °C and 60 °C) and relative humidities (10-90%), using the standard static, gravimetric method. The GAB, Halsey, Oswin and BET sorption models were tested to fit the experimental data. A nonlinear regression analysis method was used to evaluate the constants of four sorption equations. The Halsey equation gave the best fit to the experimental sorption data for a wide range of water activity while BET gave the best fit for a water activity range of 0.1-0.5. The agreement between experimental and calculated values was found to be satisfactory. The isosteric heats of desorption and adsorption of water were determined from the equilibrium data at different temperatures using the Clasius-Clapeyron equation.

    Modified Wheat Starches Used as Stabilizers in Set-Style Yogurt
    (2001) ÓZKAN,M.; YemenicioǦLU,A.; ÇITAK,B.; CemeroǦLU,B.
    Yogurt was formulated with gelatin; native wheat starch (NWS); and modified wheat starches (MWS) (acetylated cross-linked, hydroxypropylated, or hydroxypropylated cross-linked). Yogurt samples were evaluated for chemical (fat, total solids, pH, titratable acidity); microbiological (yeasts/molds and lactic acid bacteria); and physical (rheological, textural, color, syneresis) properties during 60 days of refrigerated storage. Yogurt formulated with NWS exhibited a significantly greater storage modulus (G') and firmness compared with yogurts prepared with MWS. Minimal syneresis was measured in all yogurt samples. The titratable acidity of yogurt samples increased and pH decreased during storage. Yeasts/molds were not detected while lactic acid bacteria counts decreased ∼ 1 log CFU/g by day 60 in all yogurt samples. This study showed that the characteristics of yogurt formulated with NWS and gelatin were similar, so NWS may be used as an alternative stabilizer. The MWS stabilized yogurts were stable but had different consistencies than gelatin- and NWS-stabilized yogurts.

    Distribution of Elements in Honeys and Effect of a Thermoelectric Power Plant on the Element Contents
    (1998) Üren,A.; Şerifoglu,A.; Sarikahya,Y.
    Lead, cadmium, iron, copper, zinc, manganese, calcium, magnesium and potassium contents of Turkish honeys were investigated. Most of the elements were more abundant in honeydew honeys than in flower honeys. But calcium content of honeydew honeys was smaller than in flower honeys. Considerable temporal fluctuation of elements was observed in honeydew honeys produced in the same area and from the same hives during autumn 1992, 1993 and 1994. Element contents of Turkish honeys showed high coefficients of variation, and the coefficients of variation decreased with increasing amounts of total minerals in honeys. The thermoelectric power plant which was 15-18 km away from the hives did not cause any pollution in honeys. Turkish honeys did not show any contamination of lead, cadmium, iron or zinc, and amounts of these elements were found well below the permitted limits.

    Design, Performance, and Calibration of the Cms Hadron-Outer Calorimeter
    (Springer Verlag, 2008) Karapınar, Güler
    The Outer Hadron Calorimeter (HCAL HO) of the CMS detector is designed to measure the energy that is not contained by the barrel (HCAL HB) and electromagnetic (ECAL EB) calorimeters. Due to space limitation the barrel calorimeters do not contain completely the hadronic shower and an outer calorimeter (HO) was designed, constructed and inserted in the muon system of CMS to measure the energy leakage. Testing and calibration of the HO was carried out in a 300 GeV/c test beam that improved the linearity and resolution. HO will provide a net improvement in missing E T measurements at LHC energies. Information from HO will also be used for the muon trigger in CMS. © 2008 Springer-Verlag / Società Italiana di Fisica.

    Mineral Content of Some Herbs and Herbal Teas by Infusion and Decoction
    (Elsevier Ltd., 2008) Özcan, Mehmet Musa; Ünver, Ahmet; Uçar, Tolga; Arslan, Derya
    Sage (Salvia fruticosa L.), anise (Pimpinella anisum L.), Hawthorn (Crataegus orientalis), rosemary (Rosmarinus officinalis L.), mountain tea (Sideritis spp), basil (Ocimum basilicum L.), lime flower (Tilia cordata), nettle (Urtica dioica L.), thyme (Thymbra spicata), coriander (Coriandrum sativum L.), rosehip (Rosa canina L.), mentha (Mentha piperita L.), balm (Melissa officinalis L.), tea (Camelia sinensis L.) (Black and green), sena leaf (Casia angustifolia), camomile (Matricaria chamomilla), tarragon (Artemisia dracunculus L.), cinnamon (Cinnamomum casia) and fennel (Foeniculum vulgare L.) were used as plant material in this study. Decoction was applied to R. canina, A. dracunculus and C. casia, and infusion was applied to other plant materials. Ten, 15 and 20 min were used as a time parameter for both infusion and decection. Inductive coupled plasma atomic emission spectrometry (ICP-AEs) has been used for the determination of the elements in all infusions, decoctions and plant material. The Fe (1295.65 ppm) and Mg (3178.74 ppm) of M. officinalis, P (12698.05 ppm) and Pb (3.85 ppm) of green tea, Ca (19685.70 ppm) of C. orientalis, K (29167.53 ppm), Cu (12.18 ppm) and Na (2563.86 ppm) of C. casia, Zn (26.00 ppm) of M. chamomille and Se (23.53 ppm) contents of C. sativum were higher than the other plant materials. Ca (28.621 mg/100 ml) was the highest in concentration in the infusion of C. angustifolia for 10, 15 and 20 min. Ca could not be found in black and green teas. K (231.390 mg/100 ml) and P (24.857 mg/100 ml) contents were the highest in A. dracunculus tea. Mg (16.230 mg/100 ml) content of O. basilicum was determined as the highest. In general, the minerals that difuse to the tea at higher concentrations at the 10th minute were Ag, B, Cu, Co, Fe, ln and Zn, at the 15th minute were Ag, B, Cu, Co, K, ln and Zn and at the 20th minute were Ag, B, Cu, Co, ln, Fe and K. As a result, 10 min was the optimum time for getting the minerals into the tea, and it is apparent that plants and teas are good sources of the minerals. © 2007 Elsevier Ltd. All rights reserved.

    The Cms Barrel Calorimeter Response To Particle Beams From 2 To 350 Gev/C
    (Springer Verlag, 2009) CMS HCAL/ECAL Collaborations; Sönmez, Nasuf
    The response of the CMS barrel calorimeter (electromagnetic plus hadronic) to hadrons, electrons and muons over a wide momentum range from 2 to 350 GeV/c has been measured. To our knowledge, this is the widest range of momenta in which any calorimeter system has been studied. These tests, carried out at the H2 beam-line at CERN, provide a wealth of information, especially at low energies. The analysis of the differences in calorimeter response to charged pions, kaons, protons and antiprotons and a detailed discussion of the underlying phenomena are presented. We also show techniques that apply corrections to the signals from the considerably different electromagnetic (EB) and hadronic (HB) barrel calorimeters in reconstructing the energies of hadrons. Above 5 GeV/c, these corrections improve the energy resolution of the combined system where the stochastic term equals 84.7 ± 1.6% and the constant term is 7.4 ± 0.8%. The corrected mean response remains constant within 1.3% rms. © Springer-Verlag / Società Italiana di Fisica 2009.

    Effective Stress Principle for Saturated Fractured Porous Media
    (Wiley-Blackwell, 1995) Tuncay, Kağan; Çorapçıoğlu, M. Yavuz
    An effective stress principle for saturated fractured porous media is proposed based On the double-porosity representation. Both the solid grains and the fractured porous medium are assumed to be linearly elastic materials. The derivation employs volume averaging technique to obtain macroscopic scale expressions. Two parameters, the bulk modulus of the fractured medium and bulk modulus of the porous matrix, are introduced in the formulation. The final expression reduces to the one obtained by Blot and Willis [1957], Skempton [1960], Nur and Byeerle [1971], and Verruijt [1984] when the volume fraction of the fractures vanishes, that is, for a nonfractured porous medium.

    Variation of the Light and Period of the Magnetic Cataclysmic Variable Am Her
    (IOP Publishing, 2008) Kalomeni, Belinda; Yakut, Kadri
    Ground-based, long-term optic variability of AM Her, covering the period between 2003-2008, has been conducted to study the features seen in both low and high states of the system. Low-state analysis shows the presence of short-term, low-amplitude light variations of about 0.02-0.03 mag with a mean power time between 16 s and 226 s. Brightness variations on the order of 0.7-2 mag, which could be due to the stellar activity of the component in the system, are also detected. A total of 30 years' times of minimum light given in the literature are combined with nine times of minima obtained in this study. We represented the (observed-calculated) diagram by a parabolic curve and also by two broken lines. Under the assumption of a parabolic variation, we estimate an increase in period, dP/dt = 7.5(1.2) x 10(-9) days yr(-1), with a mass transfer rate of. M = 8(2) x 10(-9) M(circle dot) yr(-1), in agreement with the previous findings by a different method.

    Evaluation of the Makam Scale Theory of Arel for Music Information Retrieval on Traditional Turkish Art Music
    (Routledge, 2009) Gedik,A.C.; Bozkurt,B.
    Current music information retrieval (MIR) methods are specifically tailored to the needs of western music. Therefore, it is not straightforward to apply these methods to non-western musics such as traditional Turkish art music (TTAM). Western music theory plays a crucial role in MIR studies. The divergence, however, between theory and practice in traditional Turkish art music (TTAM) results in a lack of a reliable theory of TTAM on which MIR techniques can be based. This is particularly true for theories regarding pitch scales and interval structures in TTAM. In this paper, we evaluate the most influential (yet disputable) theory of TTAM, Arel theory, by means of a makam classification task, to understand whether it can provide a basis for MIR studies on TTAM in a similar way western music theory provides a basis for MIR studies on western music. It is shown that Arel theory is overall successful when applied for modality finding in TTAM and that it can be improved if small modifications are introduced following pitch values obtained from musical practice. © 2009, Copyright Taylor & Francis Group, LLC.
