Optimization of the process parameters for the utilization of orange peel to produce polygalacturonase by solid-state fermentation from an Aspergillus sojae mutant strain
The effect of orange peel concentration, HCl concentration, incubation time and temperature, and inoculum size on the spore count and activity of polygalacturonase (PG) enzyme produced from Aspergillus sojae M3 by solidstate fermentation was screened using 2k factorial design. Orange peel and HCl concentrations and incubation time were significant factors affecting the responses. Optimum conditions favoring both PG and spore production from Aspergillus sojae M3 were determined as 2% orange peel and 50 mM HCl concentrations at 22 °C and 4.3 days of incubation. An overlay plot was constructed for use as a practical chart for production of high enzyme activity (>35.0 U/g substrate) and spore count (9.0 × 108 to 2.0 × 109 spore/mL) by superimposing the contours of PG activity and spore count responses. The accuracy and reliability of the constructed models on the responses was validated with the maximum calculated error rate between the predicted and actual activities at 14.1% and 22.4%, respectively. © TÜBİTAK.TUBITAK (Turkey); BMBF (Germany) through the Intensified Cooperation Project of Inten

Approach for siting a support facility for transporting supplies in emergency cases in the Republic of Bulgaria
In this paper, the author determines the most suitable transportation location for intervention in a large scale disaster in the Republic of Bulgaria, by means of the Weber Problem and the Weiszfeld method. The objective is to minimise the cost of transporting emergency supplies across the country by locating a support facility, and thus reaching the area of event at the lowest possible cost. A brief description of the Weiszfeld method is provided in the paper. Further, using recent population data of both provinces and municipalities, the method is applied respectively to obtain the results. They were compared in terms of spatial correspondence and the final facility location was fixed. Erecting the supply site is recommended to help decrease the losses
Levan-based nanocarrier system for peptide and protein drug delivery: Optimization and influence of experimental parameters on the nanoparticle characteristics
Microbial levans are biopolymers produced from sucrose-based substrates by a variety of microorganisms. There is very limited information related to the levan-based drug delivery systems. In this study, bovine serum albumin (BSA) encapsulated-levan nanoparticles were prepared using levan produced by a new Halomonas sp. Effects of polymer and BSA concentrations and rotating speed on in vitro characterization of the nanoparticles were investigated. The size of levan nanoparticles, with the surface charges +4.3 mV to +7.6 mV, changed between 200 nm and 537 nm. The encapsulation capacity of the particles changed between 49.3% and 71.3% depending on the levan concentration used in the formulation. The cumulative in vitro release of protein from the particles was shown to be controlled release of BSA. This study affirmed the suitability of levan by Halomonas sp. to be used as a nanocarrier system for potential delivery of macromolecular drugs such as peptides and proteins. (C) 2010 Elsevier Ltd.

Dilute-acid hydrolysis of apple, orange, apricot and peach pomaces as potential candidates for bioethanol production
Chemical composition of four selected fruit pomaces (agro-industrial wastes) was evaluated. The effect of temperature, time, acid concentration and solid:liquid (S:L) ratio on dilute-acid hydrolysis of selected pomaces were investigated using 24 factorial and central composite design and optimum hydrolysis conditions were determined. A preliminary study was initiated using apple hydrolysate and the fungus Tricoderma harzianum in order to explore and demonstrate their potential uses in bioethanol production. Chemical composition of pomaces was promising as fermentation media. The highest reducing sugar yield from the optimization step was 31%, 49%, 56% and 52% for apple, apricot, orange and peach pomaces, respectively under optimum hydrolysis conditions. Neither furfural nor hydroxmethylfurfural (HMF) were detected in hydrolysates. The highest bioethanol production (1.67 g/L) was obtained in 6 days in a non-static incubator using Tricoderma harzianum pregrown in minimal medium. It was demonstrated that selected pomaces holds potential for bioethanol production and can be eliminated without being potential waste problem to the environment, with economical return. Although, this work is an initial study in showing the potential of these pomaces and T. harzianum in bioethanol production, an extensive study on the optimization of fermentation parameters is recommended for further increase of bioethanol production.

Investigation on drying of brined caper fruits by different methods
Fen Bilimleri Enstitüsü, Gıda Mühendisliği Ana Bilim DalıBu çalışmanın amacı; salamura edilmiş kapari meyvelerinin çeşitli yöntemlerle kurutulmasını incelenmesi ve katma-değeri olan bir ürün geliştirilmesidir. Bu amaçla ilk olarak kaparilerin ultrasonikasyon (US) ile ön işlemesinin uygunluğu tespit edilmiştir. Bunu takiben kırınım pencereli kurutma (KPK), etüvle konveksiyonla kurutma (EKK) ve vakumlu etüvde kurutma (VEK) yöntemlerine ön işlem olarak 10, 20, 30 ve 40 dak US uygulanmış olan örneklerin kinetik verileri elde edilmiş ve matematiksel modellerle ifade edilmiştir. Ayrıca etkin nem difüziviteleri hesaplanmıştır. Kaparilerin kurutulmasında; US işleminin süresi, kurutma sıcaklığı ve kurutma yöntemi faktörlerinin kurutma süresi, toplam renk değişimi, rehidrasyon oranı, sertlik ve spesifik enerji tüketimi değişkenleri üzerine olan etkileri ise deney tasarımı ve yanıt yüzey yöntemi kullanılarak optimize edilmiştir. Belirlenen optimum koşullar her bir kurutma yöntemi için deneysel olarak doğrulanmıştır. Çalışma kapsamında son olarak EKK yöntemi ile dehidrasyon ve rehidrasyon işlemleri esnasında elde edilen görüntüler, görüntü işleme yöntemi ile işlenmiş ve geometride meydana gelen değişimler belirlenmiştir. Mikrotomografi yöntemi ile de kuruma esnasında zamana karşı meydana gelen hacim değişimi ortaya çıkarılmıştır. Bu tez çalışması kapsamında kapari meyvelerinin kurutulmuş bir ürüne dönüştürülmesi için en uygun ön işlem ve kurutma koşulları üç farklı yöntem için sergilenmiştirThe aim of this study is to examine the drying of brined caper fruits by various methods in order to develop a value-added product. For this purpose, firstly, the suitability of pretreatment of capers with ultrasonication (US) was determined. Following this, the kinetic data of the samples, which were applied 10-, 20-, 30- and 40-minutes US as a pretreatment to refractive window drying (RWD), convective drying (CD) and vacuum drying (VD) methods, were obtained and expressed with mathematical models. In addition, effective moisture diffusivities were calculated. In the drying of capers, the effects of US treatment time, drying temperature and drying method factors on drying time, total color change, rehydration rate, hardness and specific energy consumption variables were optimized using experimental design and response surface methodology. The optimum conditions obtained for each drying method were validated experimentally. In the last part of the study, the images obtained during the dehydration and rehydration processes with the CD method were processed with the image processing method and the changes in the geometry were determined. With the microtomography method, the volume change that occurred against time during drying was revealed. Within the scope of this thesis, the most suitable pretreatment and drying conditions for the transformation of caper fruits into a dried product were presented for three different methods
Geç tunç ve demir çağlarında dini bir manifesto olarak Güneydoğu’da Hitit kaya kabartmaları
Cataloged from PDF version of article.Includes bibliographical references (leaves 91-95).The LBA rock reliefs are the works of the last three or four generations of the Hittite Empire. The first appearance of the Hittite rock relief is dated to the reign of Muwatalli II who not only sets up an image on a living rock but also shows his own image on his seals with his tutelary deity, the Storm-god. The ex-urban settings of the LBA rock reliefs and the sacred nature of the religion make the work on this subject harder because it also requires philosophical and theological evaluations. The purpose of this thesis is to evaluate the reasons for executing rock reliefs, understanding the depicted scenes, revealing the subject of the depicted figures, and to interpret the purposes of the rock reliefs in LBA and IA. Furthermore, the meaning behind the visualized religious statements will be investigated. Whether there was a cultural continuity in the IA in the context of iconography, functions, and meanings will be proposed. Various iconographies depicted on the living rock and used on the royal seals reveal that the politico-religious discourse of the Hittite kingship gained a new ideological perspective. The IA rock monuments indicate a Hittite cultural inheritance along with the Assyrian influence. However, IA states also produced a number of inscribed colossal statues and stelae, and rock reliefs. In general, the Hittites were executing rock monuments which carry religious elements as a way of promulgating their political propaganda, and attributing the authority of the king to the mighty god/s.by Hande Köpürlüoğlu
Assessment of abbott architect 25-oh vitamin D assay in different levels of vitamin D
There is increasing requests of Vitamin D test in many clinical settings in recent years. However, immunoassay performance is still a controversial topic. Several diagnostic manufacturers have launched automated 25-hydroxyvitamin D (25-OH D) immunoassays in the past decade. We compared the performance of Abbott Architect 25-OH D Vitamin immunoassay with liquid chromatography-tandem mass spectrometry systems (LC-MS/MS) to evaluate immunoassay performance, especially in deficient groups. Eighty human serum samples were analyzed with Architect 25-OH D vitamin kit (Abbott Diagnostics, Lake Forest, IL, USA) and LC-MS/MS systems (Zivak Technology, Istanbul, Turkey). The results of the immunoassay method were compared with the LC-MS/MS using Passing-Bablok regression analysis, Bland-Altman plots and correlation coefficient analysis. We also evaluated results in four levels of D vitamin as a severe deficiency, deficiency, insufficiency, and sufficiency. Architect showed 9.59% bias from LC-MS/MS with smaller mean. Passing-Bablok regression analysis demonstrated the value of 0.95 slope and had a constant bias with an intercept value of -4.25. Concordance correlation coefficient showed moderate agreement with the value of 0.918 (95% CI 0.878-0.945). Two methods revealed good interrater agreement (kappa = 0.738). While the smallest bias determined in deficiency (9.95%) group, the biggest was in insufficiency (15.15%). Architect 25-OH D vitamin immunoassay can be used in routine measurements but had potential misclassification of vitamin D status in insufficient and deficient groups. Although there are recent standardization attempts in 25-OH D measurements, clinical laboratories must be aware of this method. © 2019 Esin Avci, Süleyman Demir, Diler Aslan, Rukiye Nar, Hande Şenol, published by Sciendo
