(Istanbul Univ-cerrahpasa, 2021) Sudağıdan, Mert; Yurt, Mediha Nur Zafer; Taşbaşı, Behiye Büşra; Acar, Elif Esma; Ömeroğlu, Esra Ersoy; Uçak, Samet; Aydın, Ali
Cheese microbiota may contain various bacterial species due to the use of different types of milk, rennet, and herbs. In this study, the distribution of the dominant bacteria present in the microbiota of herby cheese samples (n = 13) were examined by the next generation sequencing (NGS) technique. DNA was extracted both directly from cheese samples and after pre-enrichment. The metagenomic analysis of the NGS results revealed that Firmicutes were dominant both in DNA directly extracted from herby cheese (KOP), and pre-enriched samples (OP), at the phylum level. At the genus level, Lactobacillus, Lactococcus, and Streptococcus were dominant in the KOP samples, whereas in the OP samples, Enterococcus, Streptococcus, and Bacillus were determined as the dominant bacterial genera. Although Lactococcus raffinolactis and Streptococcus salivarius were dominant in the KOP samples, Enterococcus faecalis and S. salivarius were dominant in the OP samples. The Shannon species diversity index and principal coordinates analysis (PCoA) were used to determine the distribution in KOP and OP samples at the genus level. The PCoA of KOP-10, KOP-11, KOP-2, and KOP-7, KOP-3, and KOP-6 samples showed the wide distribution, whereas KOP-5, KOP-8, KOP-9, and KOP-14 herby cheese samples were closely related. The OP samples, especially OP-7 and OP-14, showed wide distribution in comparison to other OP samples. Finally, the dominant bacterial communities were identified by DNAbased metagenomic analysis, and this is the first report to elucidate the microbiota of herby cheese produced in Turkey using the NGS technique.

Absorption and optical conduction in InSe/ZnSe/InSe thin film transistors
(World Scientific Publ Co Pte Ltd, 2016) Al Garni, S. E.; Qasrawi, A. F.; Department of Electrical & Electronics Engineering
In this work, (n)InSe/(p)ZnSe and (n)InSe/(p)ZnSe/(n)InSe heterojunction thin film transistor (TFT) devices are produced by the thermal evaporation technique. They are characterized by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersion X-ray spectroscopy and optical spectroscopy techniques. While the InSe films are found to be amorphous, the ZnSe and InSe/ZnSe films exhibited polycrystalline nature of crystallization. The optical analysis has shown that these devices exhibit a conduction band offsets of 0.47 and valence band offsets of 0.67 and 0.74 eV, respectively. In addition, while the dielectric spectra of the InSe and ZnSe displayed resonance peaks at 416 and 528 THz, the dielectric spectra of InSe/ZnSe and InSe/ZnSe/InSe layers indicated two additional peaks at 305 and 350 THz, respectively. On the other hand, the optical conductivity analysis and modeling in the light of free carrier absorption theory reflected low values of drift mobilities associated with incident alternating electric fields at terahertz frequencies. The drift mobility of the charge carrier particles at femtoseconds scattering times increased as a result of the ZnSe sandwiching between two InSe layers. The valence band offsets, the dielectric resonance at 305 and 350 THz and the optical conductivity values nominate TFT devices for use in optoelectronics.

Achieving success in supply chain management software by agility
(Springer Verlag, 2007) Mishra,D.; Mishra,A.; Computer Engineering; Software Engineering
Supply chain management is comprehensive software. Due to its scope and unpredictable, complex and unstable requirements, it is not possible to develop it with predictable development process models. Agile methodologies are targeted towards such kind of problems that involves change and uncertainty, and are adaptive rather than predictive. The aim of this paper is to analyze the management and development methodologies used in development of supply chain management software. This paper shows how to overcome risks and handicaps in each development phase of a complex inventive project. It also provides a set of guidelines regarding how the agile methods may be adopted, combined and used in these kinds of projects. © Springer-Verlag Berlin Heidelberg 2007.

(Turkiye Klinikleri, 2021) Bayindir,H.; Baranoğlu,B.; Yazici,A.; Software Engineering; Manufacturing Engineering
An adaptive algorithm for evaluation of singular and near singular integrals in 3D is presented. The algorithm is based on successive adaptive/selective subdivisions of the element until a prescribed error criteria is met. For evaluating the integrals in each subdivision, Gauss quadrature is applied. The method is computationally simple, memory efficient and can be applied for both triangular and quadrilateral elements, including the elements with nonplanar and/or curved surfaces. To assess the method, several examples are discussed. It has shown that the algorithm performs well for singular and near-singular integral examples presented in the paper and evaluates the integrals with very high accuracy. © TÜBİTAK

Adaptive Stimulus Design for Dynamic Recurrent Neural Network Models
(Frontiers Media Sa, 2019) Doruk, R. Ozgur; Zhang, Kechen; Electrical-Electronics Engineering
We present an adaptive stimulus design method for efficiently estimating the parameters of a dynamic recurrent network model with interacting excitatory and inhibitory neuronal populations. Although stimuli that are optimized for model parameter estimation should, in theory, have advantages over nonadaptive random stimuli, in practice it remains unclear in what way and to what extent an optimal design of time-varying stimuli may actually improve parameter estimation for this common type of recurrent network models. Here we specified the time course of each stimulus by a Fourier series whose amplitudes and phases were determined by maximizing a utility function based on the Fisher information matrix. To facilitate the optimization process, we have derived differential equations that govern the time evolution of the gradients of the utility function with respect to the stimulus parameters. The network parameters were estimated by maximum likelihood from the spike train data generated by an inhomogeneous Poisson process from the continuous network state. The adaptive design process was repeated in a closed loop, alternating between optimal stimulus design and parameter estimation from the updated stimulus-response data. Our results confirmed that, compared with random stimuli, optimally designed stimuli elicited responses with significantly better likelihood values for parameter estimation. Furthermore, all individual parameters, including the time constants and the connection weights, were recovered more accurately by the optimal design method. We also examined how the errors of different parameter estimates were correlated, and proposed heuristic formulas to account for the correlation patterns by an approximate parameter-confounding theory. Our results suggest that although adaptive optimal stimulus design incurs considerable computational cost even for the simplest excitatory-inhibitory recurrent network model, it may potentially help save time in experiments by reducing the number of stimuli needed for network parameter estimation.

Amine-functionalized graphene nanosheet-supported PdAuNi alloy nanoparticles: efficient nanocatalyst for formic acid dehydrogenation
(Royal Society of Chemistry, 2018) Bulut,A.; Yurderi,M.; Kaya,M.; Aydemir,M.; Baysal,A.; Durap,F.; Zahmakiran,M.; Chemical Engineering
Formic acid (HCOOH), a major by-product of biomass processing with high energy density, stability and non-toxicity, has a great potential as a safe and a convenient liquid hydrogen (H2) storage material for combustion engines and fuel cell applications. However, high-purity hydrogen release from the catalytic decomposition of aqueous formic acid solution at desirable rates under mild conditions stands as a major challenge that needs to be solved for the practical use of formic acid in on-demand hydrogen generation systems. Described herein is a new nanocatalyst system comprised of 3-aminopropyltriethoxysilane-functionalized graphene nanosheet-supported PdAuNi alloy nanoparticles (PdAuNi/f-GNS), which can reproducibly be prepared by following double solvent method combined with liquid-phase chemical reduction, all at room temperature. PdAuNi/f-GNS selectively catalyzes the decomposition of aqueous formic acid through the dehydrogenation pathway (∼100% H2 selectivity), in the absence of any promoting additives (alkali formates, Brønsted bases, Lewis bases, etc.). PdAuNi/f-GNS nanocatalyst provides CO-free H2 generation with a turnover frequency of 1090 mol H2 mol metal−1 h−1 in the additive-free dehydrogenation of formic acid at almost complete conversion (≥92%) even at room temperature. The catalytic activity provided by PdAuNi/f-GNS nanocatalyst is higher than those obtained with the heterogeneous catalysts reported to date for the additive-free dehydrogenation of formic acid. Moreover, PdAuNi/f-GNS nanoparticles show high durability against sintering, clumping and leaching throughout the catalytic runs, so that the PdAuNi/f-GNS nanocatalyst retains almost its inherent catalytic activity and selectivity at the end of the 10th recycle. © The Royal Society of Chemistry and the Centre National de la Recherche Scientifique.

ANALYSIS OF THE INDUSTRIAL HERITAGE IN ZONGULDAK AND RECOMMENDATIONS FOR ITS REUTILIZATION
(Univ Alexandru Ioan Cuza Iasi, Arheoinvest interdisciplinary Platform, 2021) Fidan, Fuat; Onur, Selahattin; Architecture
Significant changes and transformations took place in the structure of societies and cities with the Industrial Revolution besides technological developments. During this period, industrial cities and industrial societies emerged as a result of the settlements that developed near the mines opened to increase production. A similar process took place in Zonguldak; the coal mines in the region allowed it to be established and developed as a port city in 1849. There are industrial structures and facilities in the city that have remained dysfunctional over time. These industrial values, which gained identity to the city and region where they are located, need to be conserved as a heritage. The aim of the study was to analyze, discuss, and develop recommendations for the current state of this industrial heritage. In this context, first, the industrialization process in the city was examined and the urban effects of the coal industry and its role in the development of other industries were revealed. Then, the status of the industrial heritage and the current ideas and approaches regarding this heritage were determined through different industrial building/facility/campus examples in Zonguldak. At this point, recommendations for conservation and recovery of these values in the city have been made.

The Analysis of the Silhouette Alteration in Ottoman Women's Dresses (Entari) From Classical to Modern Period
(Milli Folklor dergisi, 2019) Cegindir, Nese Yasar; Kuru, Songul; Textile and Fashion Design
The main objective of this article is to review the change of silhouette in women's entari varying from classical to modern period in the Ottoman Empire by use of visual sources. The study is deemed important because it maintains preserves and introduces "the change in the regular wear of women of middle and upper socio-culturalleconomic group in the Ottoman Empire" into the national and international literature, contributes to region-scaled cultural heritage and constitutes a scientific source for those who are interested in this subject. Materials of the descriptive study are as follows: printed and on-line documents regarding clothing culture of the Ottoman Empire, especially from the rise of the Empire forward, itineraries of local and foreign voyagers, engravings, miniatures and photos of clothes in the collections of museums. The samples of the study are eight photos chosen on purpose since they reflect the change of clothing silhouette in the best possible way. Visual materials chosen have been converted into graphical silhouette by use of the Macromedia Free Hand MXa programme. Details of each clothing silhouette were analyzed by comparison with preceding one by use of the visual analysis techniques. The change of silhouettes in comparison with preceding one has been examined within the frame of alphabetic that constitutes the fashion literature and silhouettes of women's clothing. Data acquired from each photograph were sorted chronologically and interpreted by combining with alphabetical silhouettes and graphics which were formed alongside clothing silhouette characteristics. Three-step change in women's entari has been observed as a result of the study. H-shaped silhouette of entari, which is simple, plain and without detail and taken over from the Seljug Empire, interacted with the Europe thanks to improvement of cultural relations with the Europe following the transition to the settled life. In this process, thanks to the technics of new cut, merging, forming and fixating the form, entaris fitting the body all the better have turned into X silhouette. As of the Tanzimat Reform Era, fashion concept was adopted and entari of intellectual Ottoman women transformed into S-silhouette which was formed by Western women by use of artificial tools.

Analyzing two decades of intimate partner femicide-suicides in T?rkiye*
(Elsevier Sci Ltd, 2023) Cavlak, Mehmet; Odabasi, Aysun Balseven; Mutlu, Niluefer Dilara Ar; Erbaydar, Nueket Paksoy
Intimate partner femicide-suicide (IPF-S) is an understudied subgroup of homicide-suicide deaths. Limited research has been conducted on IPF-Ss in the Eastern Mediterranean region. This study thus aimed to evaluate the characteristics of IPF-Ss that occurred in Turkiye between 2000 and 2019. IPF-Ss (n = 226) were extracted from electronic news stories. Data on victims, perpetrators, their relationships, and incidents of murder and suicide were collected. Descriptive statistics were calculated, and logistic regression analysis, mortality rates, and proportion of IPF-S in femicide calculations were conducted, showing that 13.3% of the femicides (n = 1699) were IPF-Ss. The IPF-Ss increased in 5-year intervals and were the highest during the 2015-2019 period (62.5%). Victims were married in 48.2% of the cases and 56% were aged <35 years, while 51.3% of the perpetrators were married and 52.6% were aged >40 years. In 42.0% of the cases, the perpetrator lived with the victim. Most (79.2%) of the cases took place in urban settlements, and the perpetrators used firearms in 84.1% of femicide cases. Firearm use was the most common method in cases where IPF-S was planned (OR = 2.98), when the IPF-S method was the same (OR = 29.6), and when the perpetrator committed suicide (OR = 7.82). In addition, it was found that firearm ownership is an important risk factor for IPF-S in Turkiye. Therefore, we recommend legislation to restrict firearms, as well as new measures to prevent illegal access to weapons.

Anatomical and Clinical Evaluation of Tympanic Tegmen and Mastoid Bone with Multidetector Computed Tomography
(Soc Chilena Anatomia, 2023) Sever, Sinem Nur; Cetin, Huseyin; Caliskan, Selma; Akkasoglu, Sinem; Basic Sciences
Tegmen level and mastoid bone thickness are important parameters of surgical risk in middle ear and mastoid region surgeries. This retrospective cohort study was conducted to provide a risk classification for the mastoid and middle ear regions. The study population comprised of 300 patients who underwent multidetector computed tomography (MDCT) for various indications. Patients with no pathology that disrupted the structure of the temporal region were included in the study. A risk classification was generated by analyzing the data obtained from mastoid and tympanic tegmen depths and the mastoid bone thickness by MDCT. The mastoid and tympanic tegmen were lower on the right side than on the left. In women, the right-sided mastoid bone thickness and mastoid tegmen were lower, and low-level tympanic and mastoid tegmen on the left and thin right mastoid bones were more common. According to the risk classifications for mastoid and middle ear region surgeries, women demonstrated a higher risk than men. In addition, as the thickness of the mastoid bone increased, the levels of the mastoid and tympanic tegmen increased. The present study provides a proper risk classification that may be helpful for preoperative risk assessment prior to middle ear and mastoid region surgery.
