Nitrogen monoxide (NO) and nitrogen dioxide referred as NOx are one of the most important air pollutants in the atmosphere. Biological NOx removal technologies have been developing to reach a cost-effective control method for upcoming stringent NOx emission standards. The BioDeNOx system was seen as a promising biological NOx control technology which is composed of two reactors, one for absorbing of NO in an aqueous Fe(II)EDTA2- solution and the other for subsequent reduction to N2 gas in a biological reactor by the denitrification process. In this study, instead of two discrete reactors, only one jet-loop bioreactor (JLBR) was utilized as both absorption and denitrification unit and no chelate-forming chemicals were added. In other words, the advantage of better mass transfer conditions of jet bioreactor was used instead of Fe(II)EDTA2-. The process was named as Jet-BioDeNOx. The JLBR was operated for the removal of NOx from air streams containing 500-3000 ppm NOx and the results showed that the removal efficiency was between 81% and 94%. The air to liquid flow ratio (Q(G)/Q(RAS)) varied in the range of 0.07-0.12. Mathematical modelling of the system demonstrated that the removal efficiency strongly depends on this ratio. The high mass transfer conditions prevailed in the reactor provided a competitive advantage on removing NO gas without any requirement of chelating chemicals.
Gonca KUZAY DEMİR * ÖZ: 19. yüzyıl sonrasında Alan Dundes'in "Halk kimdir?" başlıklı makalesinin ardından, değişen ve değişirken gelişip genişleyen halk bilimi, 21. yüzyılda artık halkı kırsalda, eğitimsiz veya çok az bir eğitim almış insan gruplarının arasında aramaktan uzaklaşmış durumdadır. Günümüzde halk bilimi araştırmacıları disiplinler arası yaklaşımlarla çevresini sorgulamakta ve insanları bir araya getiren unsurları tespit ederek ekonomik, kültürel ve sosyal açıdan fayda sağlamaya dönük çalışmalar yapmaktadır. Son yüzyıllarda gittikçe artan "kent folkloru" olarak adlandırabileceğimiz, "kenti" ve "kentli" kimliğini sorgulayan çalışmalar, kaynağını yaşanılan zamanda ve mekânda bulmaktadır. Kent kültürünü meydana getiren kentli insanların temel mekânlarından birini pazarlar oluşturmaktadır. Alışveriş ve eğlence mekânlarından olan pazarlar, aynı kentte yaşayan çok sayıda insanın üretim ve tüketim alışkanlıkları doğrultusunda bir araya geldikleri toplumsal mekânlardan biridir. Türk kültüründe pazar, toplumsal bir mekân olmasının ötesinde bir geleneği ifade etmektedir. Bununla birlikte halk biliminde pazarlar ve pazar çevresinde sürdürülen gelenek hakkında bir çalışma bulunmamaktadır. Bu makalede; halk bilimi araştırmalarında çok fazla yer almayan pazarlar, teorik açıdan değerlendirilecektir. Öncelikle pazarlar için kullanılan terminoloji verilecek, daha sonra pazarlar bağlam, yapı, kapsam ve işlev özellikleri bakımından ele alınacaktır. Böylelikle köyden kente gündelik hayatın bir parçası olan pazarlar halk bilimsel açıdan değerlendirilerek, halk biliminde daha önce çalışılmamış bir saha olarak sonraki çalışmalara teklif edilecektir.
Datamatrix which was developed by Japanese Denso firm in 1994 is a type of two-dimensional barcode which can be scanned with the digital camera of mobile devices. Datamatrix application which is based on Near Field Communication/NFC was designed for contactless/fast/secure communication between electronic devices in close distances. Thanks to the datamatrix coding system, every kind of limitless content transfer such as information/message/video etc can be done in a limited area. Recorded images are analyzed and barcode content directs users to internet/e-mail address-telephone number-sms/mms/geographical location information. Through datamatrix technology whose existence and utilizability has been verified in various fields, descriptive information can be encoded rapidly and practically. In musical training and education technology as well as in the material and equipment developing process, musicologists have declared that the datamatrix coding system can be used as visual/auditory alternative transfer or adaptation instrument which fulfills the function of making rapid and active connection and communication between physical reality and virtual reality. Any kind of literary and musical texts as well as voice records of Turkish folk music, which is defined as a kind of verbal/artistic performance, can be encoded in the axis of performance theory which is one of the folklore analysis models and linguistical approaches in ethnomusicology.
In dialectology as a result of researches carried out with local variation method in the axis of linguistic approaches it was emphasized by dialectologists who draw attention to the term dia (every kind of dialogic term/concept/element in the axis of dialogical)-lect (every kind of dialinguistic variant/alternate/range in the axis of dialinguistical) that dialinguistic properties which sustain according to dialinguistic laws, in folklectology as a result of researches carried out with local variation method in the axis of linguistic approaches it was emphasized by folklectologists who draw attention to the term folk (every kind of folkloric term/concept/element in the axis of folklogical)-lect (every kind of folklinguistic variant/alternate/range in the axis of folklinguistical) that folklinguistic properties which sustain according to folklinguistic laws, in musicolectology as a result of researches carried out with local variation method in the axis of linguistic approaches it was emphasized by musicolectologists who draw attention to the term musico (every musicologic term/concept/element in the axis of musicological)-lect (every kind of musicolinguistic variant/alternate/range in the axis of musicolinguistical) that musicolinguistic properties which sustain according to musicolinguistic laws are sustained in the the existence of phonetics/morphology/vocabulary criteria together with local/universal correlations on theorical/executive infrastructure of Turkish folk music literary/musical texts in the axis of performance/execution display theory which is one of the foklore analysis models and linguistical approaches in ethnomusicology. Trasnferrial/adaptation process of dialect-folklect-musicolect properties on Turkish Folk Music Phonetic Notation System Database/TFMPNS D will be carried out in the axis of dialinguistic/folklinguistic/musicolinguistic laws through Urfa region sample.
