    Perancangan Dashboard Mobil Pedesaan Multiguna

    Full text link
    Mobil GEA yang merupakan mobil nasional akan dikembangkan menjadi mobil pedesaan multiguna. Salah satu bagian dalam mobil GEA yang menjadi perhatian adalah dashboard. Selama ini dashboard mobil GEA diproduksi secara manual, yaitu menggunakan proses wet lay-up dengan bahan komposit. Rencana ke depan produksi mobil pedesaan multiguna adalah produksi massa. Untuk memenuhi kebutuhan tersebut dirancang proses cetakan injeksi plastik (injection molding) untuk pembuatan dashboard mobil pedesaan multiguna. Dibuat dua buah konsep dashboard, yaitu konsep A dan konsep B yang mengacu pada list of requirements. Simulasi pembebanan dan proses injection molding dengan material acrylonitrile butadiene styrene dilakukan pada kedua konsep tersebut. Beban yang diberikan adalah beban statis sebesar 100 N pada bagian atas dashboard dan 50 N pada masing-masing laci dashboard. Dari hasil perancangan, khususnya proses scoring ditetapkan konsep B sebagai alternatif dashboard untuk mobil pedesaan multiguna. Dari hasil simulasi pembebanan yang dilakukan, didapatkan nilai tegangan maksimal yang terjadi pada dashboard adalah 1.35 MPa dengan defleksi sebesar 0.237 mm. Sedangkan dari hasil simulasi proses injection molding didapatkan waktu produksi tiap dashboard adalah 246 detik (4.1 menit) dengan gaya cekam maksimal 2370 ton

    Blindiadelphus campylopodus, Sphagnum quinquefarium, Gymnomitrion obtusum and Anastrophyllum minutum are reported as new for Turkey and Southwest Asia, following a recent bryological excursion to the Sis Mountain of Turkey. Also, genera Blindiadelphus and Anastrophyllum are given as new record for bryophyte flora of Turkey. Brief descriptions, illustrations, geographic distribution, ecology and comparisons with morphologically similar species are presented

    Grimmia ramondii (Lam and DC.) Margad (Grimmiaceae) is recorded for the second time in Turkey. Additionally it is new to southwestern Asia with the exception of Turkey. The specimen was collected during a botanical field trip in the Hatila Valley National Park (Artvin-Turkey) in 2006. Illustrated descriptions of the species along with a short note on the species and its distribution in and outside Turkey are provided. © 2008 Asian Network for Scientific Information

    WOS: 000377116600011The genus Brotherella Loeske ex Fleisch., B. erythrocaulis (Mitt.) Fleisch. (Sematophyllaceae) and Encalypta pilifera Funck in Sturm (Encalyptaceae) were reported for the first time from Turkey. These are also new records for the Mediterranean, the Middle East and Southwest Asia. The record of B. erythrocaulis is from Artvin region (Turkey), and that of E. pilifera is based on collections from Afyon, Burdur, Igdir and Izmir regions (Turkey). Descriptions, illustrations, geographic distribution, diagnostic characters of the species and comparisons with morphologically similar taxa are presented.TUBITAKTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [111T857, 108T566]This study was supported by TUBITAK (projects 111T857 and 108T566)

    In this work, the essential oils obtained by hydrodistillation from Neckera complanata (Hedw.) Huebener and Neckera crispa Hedw (Neckeraceae) were analyzed by GC-FID and GC-MS. Twenty-one compounds in the oil of N. complanata, representing 71.61 % and forty-two compounds in the oil of N. crispa, representing 82.12 %, were identified. The essential oil of N. crispa was rich in terpenes (58.68 %) with ?-phellandrene (20.00 %), camphene (10.36 %), ?-bisabolene-E (5.51 %) and ?-pinene (3.49 %) as the major components, respectively. 3-Octanone (22.26 %) and limonene (2.97 %) were the major constituents of the essential oil of N. complanata. The antimicrobial activities of the isolated essential oils of the mosses were also investigated. The essential oil of N. complanata showed only moderate antibacterial activities against Staphylococcus aureus, Enterococcus faecalis and Bacillus cereus with 576 ?g/mL (each). But all the oils showed good antimycotic activity against Candida albicans with in the range of 573-576 ?g/mL, respectively. The aim of this work was to characterize the variation in the essential oil composition of N. complanata and N. crispa grown in Turkey and to identify environmental factors associated with differences in essential oil composition as well as to evaluate their antimicrobial activity

    The epiphytic bryophyte flora and vegetation of boraboy and destek forests (Amasya, Turkey)

    In this study, epiphytic bryophyte flora and vegetation were investigated of Boraboy and Destek forests in Amasya province (Turkey). A total of 22 bryophyte taxa (19 mosses, 3 liverworts) were recorded in the research site. As a result of the investigation of 32 sampling releves taken from the trunks by the Braun-Blanquet method, two epiphytic bryophyte associations (Orthotrichetum pallentisand Orthotrichetum striati) belonging to the Ulotion crispaealliance were detected. Among these syntaxa Orthotrichetum pallentiswas recorded for the first time from Turkey. Furthermore, the life forms and life strategies spectrum in syntaxa were analyzed. Analysis result indicates a distinct correlation between life forms, strategies and ecological conditions of the area. Weft and cushion are dominant life forms, Perennial stayers with high sexual reproductive effort is dominant life strategy in the syntaxa. In addition, the ecological characteristics of bryophyte taxa were evaluated. According to these results the largest number of epiphytic bryophytes in the area are mesophytic, sciophyte and subneutrophyte. © 2017, Pakistan Botanical Society. All rights reserved
