Keanekaragaman Laba-Laba ( Arachnida ) Pada Ketinggian Tempat Yang Berbeda Di Taman Nasional Gunung Merbabu Kabupaten Boyolali Tahun 2012

Latar belakang penelitian ini berdasarkan ekosistem yang terdapat di Taman Nasional Gunung Merbabu yaitu ekosistem hutan hujan tropis musim pegunungan bawah (1000-1500 m dpl), hutan hujan tropis musim pegunungan atas (1500-2400 m dpl) dan hutan hujan tropis musim sub-Alpin (2400-3142 m dpl). Selain itu belum ada penelitian mengenai keanekaragaman laba-laba (Arachnida) di Taman Nasional Gunung Merbabu. Tujuan penelitian ini untuk mengetahui keanekaragaman laba-laba (Arachnida) di Taman Nasional Gunung Merbabu Kabupaten Boyolali Tahun 2012. Metode yang digunakan metode kuadrat dengan sistem plot, luas plot setiap stasiun 2700 m2. Dengan lokasi penelitian dibagi menjadi 3 stasiun, yaitu stasiun A (1500 m dpl), stasiun B (1800 m dpl) dan stasiun C (2400 m dpl). Selanjutnya data pengamatan dianalisis dengan Indeks Simpson yang berfungsi untuk mengetahui besar keragaman dan dominasi laba-laba. Keanekaragaman paling tinggi pada stasiun A (1500 m dpl) yaitu ada 9 jenis laba-laba (Arachnida) dengan jumlah total 2334 individu. Laba- laba paling banyak ditemukan dari spesies Lycosa sp. yaitu 2235 individu, sedangkan jumlah laba-laba terkecil yaitu Nephila pilipes yaitu 4 individu. Indeks keragaman paling tinggi terdapat di stasiun A (1500 m dpl) sebesar 0,0826, sedangkan indeks keragaman paling kecil terdapat di stasiun C (2400 m dpl) dengan nilai keragaman 0. Indeks dominasi paling tinggi terdapat di stasiun C (2400 m dpl) sebesar 1, sedangkan indeks dominasi paling kecil terdapat di stasiun A (1500 m dpl) sebesar 0,9173. Berdasarkan hasil penelitian dapat disimpulkan bahwa keragaman laba-laba (Arachnida) di Kawasan Taman Nasional Gunung Merbab termasuk rendah karena indeks diversitas (Ds) lebih kecil dari 0,5 dan semakin naiknya ketinggian suatu tempat jumlah populasi laba-laba (Arachnida) semakin berkurang

Deletion-restriction in toric arrangements

Deletion-restriction is a fundamental tool in the theory of hyperplane arrangements. Various important results in this field have been proved using deletion-restriction. In this paper we use deletion-restriction to identify a class of toric arrangements for which the cohomology algebra of the complement is generated in degree $1$. We also show that for these arrangements the complement is formal in the sense of Sullivan.Comment: v2: typos fixed, 11 pages. Accepted for publication in Journal of Ramanujan Mathematical Societ

Orbit closures of representations of source-sink Dynkin quivers

We use the geometric technique, developed by Weyman, to calculate the resolution of orbit closures of representations of Dynkin quivers with every vertex being source or sink. We use this resolution to derive the normality of such orbit closures. As a consequence we obtain the normality of certain orbit closures of type E.Comment: 11 pages, 3 figure

TEACHER TALK IN TEACHING WRITING INTERACTION OF TECHNICAL ENGINEEERING STUDENTS IN SMK SWASTA TELADAN MEDAN

This present, study focuses on the teacher talk in teaching writing which conducted in a eleventh grade classroom of SMK Swasta Teladan Medan and to describe how the categories teacher talk affect the students’ learning process during the teaching writing to the eleventh grade of SMK Swasta Teladan Medan. In this research, the FLINT is used to identify the categories of teacher talk occur during the learning process. Moreover, this study is conducted on the form of descriptive qualitative research where the researcher as the non-participant observer on the classroom. The subject of this study is a vocational high school English teacher and the eleventh graders of SMK Swasta Teladan Medan. From the data that has been taken, it is obtained that the categories of teacher talk used by the teacher in teaching writing interaction in the eleventh grader of SMK Swasta Teladan Medan are deals with feeling, praises or encourages, jokes, uses ideas of students, repeats students response verbatim, asks question, gives information, corrects without rejection, gives direction, and criticizes student behavior. More over the categories of teacher talk used also have been proven to help the students understand better about the subject and elicit students’ contribution during the learning process. In conclusion, the researcher has found that the teacher who teaches writing in an eleventh grade classroom of SMK Swasta Teladan Medan has performed some categories of the teacher talk from FLINT

Sintering characteristics of red mud compact

Scientific inventions & technological developments has raised the human life to a great height. In last few decades worldwide scientific & technical innovations for processing/development/utilization of new materials (as per the need of the society), is tremendously increasing. But, looking at the other side of the coin also implies the generation of a huge amount of industrial byproducts/wastes which is becoming a client for increasing environmental pollution & generation of a huge amount of unutilized resources. With a view to the above, this research is aimed at finding out utilization of such things/materials/industrial byproducts for value added applications & also helps to solve the environmental problems. The present piece of my research work aims at, to provide a valued input/utilization to industrial byproduct/waste (viz..red mud), being produced in huge quantity from Alumina plants, not bearing any commercial values. From the available research literatures/resources, it’s clearly understood that very little attempts have been made for finding high valued utilization of this material. Considering all these above our investigation are to process red mud for high valued applications. By now search/studies are going on for finding new ways & means available in literature regarding utilization of this material

New formats for affinity selection of human cells

Despite recent advances in stem cell biology, immunotherapy and transplantation, substantial barriers still exist in the large-scale specific separation of a discrete population of human therapeutic cells from a cell suspension. The ideal purification technique should combine high cell purity, yield and function, with fast processing and affordability. Currently, fluorescence-activated cell sorting with flow cytometry (FACS) and magnetic activated cell sorting (MACS®) are the most used methods for cell separation and purification and have been employed extensively in molecular biology, diagnostic and cell sorting applications, because they are considered to be gentle, fast and scalable. However, these methods have several key disadvantages; they are invariably expensive, yield low log cell reduction (LCR) rates, and suffer from drawbacks when applied to niche cell populations, such as those requiring multiple tandem separation steps and/or involving combined positive and negative cell selection steps. To address this challenge, a new cell affinity selection system was developed. The selectivity is based on the reversible monomeric avidin biotin interaction and it is primary designed for positive selection. The initial studies were performed on flat, nonporous, glass coverslips and the technology was then successfully transferred on high grade smooth non-porous glass beads (with a diameter of 79.12 to 118.59 μm). The multi-step layer-by-layer deposition procedure culminating in dextran-coated supports bearing monomeric avidin was rigorously characterized and subsequently employed in packed bed chromatography experiments with human erythrocytes isolated from cord blood and B lymphocytes from cell lines. The developed affinity selection platform was highly selective, efficient and, most importantly, resulted in high yields, cell purity and viability comparable with MACS® technology. Additionally scale up is possible and could be easily transferred to another chromatographic matrix with the appropriate structure
