TL;DR: Turkce ogretiminin temel araci olan metinler, ulusal ve evrensel kulturun dayandigi degerlerin ogrencilere aktarilmasi icin birer arac olma ozelliginesahiptir as discussed by the authors.
Abstract: Turkce ogretiminin temel araci olan metinler, ulusal ve evrensel kulturun dayandigi degerlerin ogrencilere aktarilmasi icin birer arac olma ozelliginesahiptir. Bu dogrultuda Milli Egitim Bakanligi Yayinlari tarafindan basilan 7.sinif Turkce ders kitabinda yer alan okuma metinlerinin hangi degerleri ilettigini tespit etmek ve bu degerlerin dagilimini belirlemek bu arastirmanin amaciniolusturmaktadir. Ilkogretim 7. sinif Turkce ders kitabindaki okuma metinlerinde degerlere yer verilme durumunu belirlemeye yonelik olarak gerceklestirilenbu calismanin evrenini, incelenen Turkce ders kitabi olusturmaktadir.Arastirmada, evrende bulunan okuma metinleri degerlendirilmistir. Degerlerkonusunda bir liste olusturulmus ve Turkce ders kitabi incelendikce bu listesekillendirilip gelistirilmistir. Calismanin surecinde Turkce ders kitaplari olusturulurken metinlerde degerlere yonelik ogelerin yeterince yer almasi gerektigisonucuna ulasilmistir. Bu acidan calismanin, ders kitabi yazarlarina, bu konudadaha sonra calisma yapacak arastirmacilara ve Turkce egitimi alanina katki saglayacagi ve yardimci olacagi dusunulmektedir
TL;DR: In this article , an ANSYS simulation was used to evaluate the thermal properties of a commercial product block design with an extruder heat block and the results obtained from the simulation were satisfactory when compared with the thermal behavior of a conventional product block.
Abstract: 3D printers are the most common and popular method of additive manufacturing technology and provide fusion of materials using thermal effects. This phenomenon makes that temperature the most important factor affecting printing quality. The temperature is provided by the Aluminium Extruder Heat Block in the extruder and the temperature regime must be constant according to the type of printing material. The objective of this study is to make aluminium Extruder Heat Block designs with high thermal efficiency to keep the temperature regime constant and to analyse the thermal behaviour of new designs with a commercial product block design using ANSYS simulation. The materials of the blocks were chosen the same and the temperature distribution of the blocks and the average heat flux were calculated by determining the boundary conditions. The results obtained from the simulation are satisfactory when compared with the thermal behaviour of a commercial product block.
TL;DR: In this article , changes in mechanical properties, crystallinity index, and DSC characteristics of PLA/coffee grounds with different dosages were analyzed by XRD, DSC, and mechanical property tests.
Abstract: Coffee is one of the most popular beverages in the world. It generates a waste known as coffee grounds. In this work, changes in mechanical properties, crystallinity index, and DSC characteristics of PLA/coffee grounds with different dosages were analyzed by XRD, DSC, and mechanical property tests. Statistical analysis showed that the modulus of rupture of PLA/coffee grounds 3D printing materials was maximal at 109.07 MPa and 3604 MPa when 3% coffee grounds were added. The tensile strength of the untreated PLA complex was 49.99 MPa, and the tensile strength increased from 49.99 MPa to 51.28 MPa after 3% coffee grounds were added. However, there was no significant difference between the PLA complex and PLA/coffee grounds 3D printing materials when the additions were lower than 3%. The statistical analysis showed that when the coffee grounds additions increased from 5% to 7%, the tensile strength of PLA/coffee grounds 3D printing products significantly decreased. For example, the tensile strength decreased from 49.99 MPa to 26.45 MPa with addition of 7% coffee grounds. The difference between the glass transition, cold crystallization, and melting temperatures of PLA coffee grounds 3D printing materials was almost negligible, which indicates that the thermal properties of PLA coffee grounds 3D printing materials are comparable to those of PLA, and that the processing temperature and FDM printing temperature of the PLA filament are suitable for application to the PLA coffee grounds 3D printing material system.

TL;DR: Degerler et al. as mentioned in this paper determined whether the Turkish literature curriculums and text books of Turkish literature have important duties on preserving national and sentimental values in this period and concluded that the most important feature of this period is identity development.
Abstract: OZET: Degerler, uzun zaman sonucunda icinde olustugu toplumun buyuk cogunlugu tarafindan benimsenmis; bireylerin istek, amac ve ihtiyaclarinin olusmasinda basrol oynamis olcutlerdir. Degerler, topluma anlam kazandiran ve onem verdiren olculerdir ve insanlar her zaman yasamlarini bu degerlere gore sekillendirilmis iliskiler icinde surdururler. Bu iliskiler inanc, deger, temayul, kural ve genel olarak iktisadi ve ahlaki iliskilerdir. Toplumda cogunluk tarafindan yasanmaya baslayan degerler, zamanla bireylerin mutlulugunu saglayan ozellik tasidigi icin geleneksel, toplumsal, ahlaki, dini degerler, orf ve âdetler ile milli degerler, evrensel degerler birbiri ile ic ice gecerek butunlesmis ve toplumumuzda zaman ABSTRACT: Values are the criterions that, internalized by the great deal of the society that they are formed in over a long period of time, and play a major role in formation of individuals' wishes, aims, and needs. Values are the standards that add meaning and attach importance to society; and people always maintain their life in relations shaped according to these values. These relations are beliefs, values, tendencies, rules and in general economical and moral relations. Values are lived by the majority of the society at first. But in time, because of having characteristics that obtain happiness for individuals, social, moral, and religious values integrated with the customs, traditions, national and universal values; and begun to used as "national and sentimental values". In adolescence period changes in human life occur intensively. If it is though that the most important feature of this period is identity development, it should be accepted that curriculums and text books of Turkish literature have important duties on preserving national and sentimental values in this period. The aim of this study is to determine whether the Turkish literature curriculums and text books * Bu calisma, 26-28 Mayis 2014 tarihleri arasinda Baku'de duzenlenen "21.
