5 Cara Unik Kuliah

Ada sebuah pertanyaan yang pernah melayang ke Saya (rusli) "mas gimana sih cara bertahan di Jurusan Fisika Fakultas MIPA Unej?" Pertanyaan tersebut Megelitik Juga menjadi menantang Buat ku jawab. Pertama, kenapa pertanyaan ini datang dari mahasiswa semester 2, dan selanjutnya kenapa harus saya yang menjawab. Padahal ada beberapa mahasiswa di tingkat atasnya yang memiliki predikat Cumlaude yang mungkin berpotensi menjawab pertanyaan tersebut (tapi mungkin secara teoritis bukan secara Rusliisme),
Oke Back To topic..
"mas gimana sih cara bertahan di Jurusan Fisika Fakultas MIPA Unej?"
Cara Bertahan Yang saya lakukan agar bertahan ada  cara teoritis dan cara praktiknya

1. Ketahui status, artinya setiap mahasiswa harus mengerti siapakah dirinya dan apakah statusnya. Karena hal inilah yang membedakan antara pendidikan Sekolah dengan Pengajaran Perguruan Tinggi.
2. Cintai Kampus, Jangan Cintai Orangnya  maksudnya adalah dengan mencintai lingkungan kampus, seberapun jahat dan ketatnya persaingan tidak akan menjadi beban dalam dunia perkuliahan.
3. Bertanggung Jawab, Kaidah ini sebenarnya teori umum dalam kehidupan dimana Semua orang pasti tahu dan mengerti beberapa pribahasa, kucing dipegang ekor, manusia dipegang kata-katanya (maksudnya Tanggung JAWAB).
4. Jujur, aspek mencintai kampus akan membuat orang menjadi survive/ bertahan namun yang paling penting dalam benteng Bertahan adalah Jujur, setidaknya Jujur terhadap Diri sendiri.
5. Berkarya, INILAH teori yang mendasari bahwa saya sangat senang di dunia perkuliahan dan Kampus karena tidak ada batasan kreasi serta karya yang menjadikan tolak ukur seorang mahasiswa, berdemo adalah karya dan kreasi jiwa dalam menyuarakan pendapat, namun tidak berdemo dan membuat karya jika expresi jiwa bahwa karya bisa di demonstrasi.

 Untuk mempraktikkanya sebenarnya tergantung dari pembaca budiman. kenapa?? karena Bentuk praktik adalah bentuk expresi kreasi jiwa yang tidak mungkin saya representasikan dengan keadaan yang saya alami di Perkuliahan.
Namun Saran praktikum kehidupan kampus saya adalah, berjuanglah karena menurut EINSTEIN 1% bakat dan 99% adalah kerja Keras. Dan BALASLAH semua kebaikan dan keburukan setiap orang yang bersikap kepada anda.

9 buku Hacking

Okelah para pembaca yang budiman,
kali ini saya akan membagikan sedikit buku (sebenarnya ada 9 ebook) tapi sudah saya compile jadi satu zip. pada nih buku ada beberapa macam cara mengatasi dan mengakali/ nge-Hack bagaimana sistem jaringan berjalan. Dan buku ini saya bagikan gratis, karena prosesi downloadnya yang hanya menggunakan internet akses dirumah (BONYOK yang bayar,, heheheheh ☻) oleh karena itu demi kepentingan belajar bersama cek ini.

semua ini demi kepentingan belajar. Jika nantinya buku ini digunakan dalam kepentingan Jahat ataupun kriminal Mohon maaf sebelumnya, kami tidak akan bertanggung jawab atas kerusakan apapun yang disebabkan dalam praktek dari buku ini. sekian terimakasih

Evidence for Phase Separation in Model Membrane Systems

Liquid-Ordered and Liquid-Disordered Phases

Various model membrane systems have been used by physicists and chemists to study phase separation in lipid mixtures. They are either monolayers or bilayers. Monolayers are either assembled at an air-water interface with the packing density of the lipids being adjusted by applying lateral pressure, or on a supporting lipid monolayer that is fixed to a solid support. Bilayers are used in the supported version as described above, or in the form of vesicles. The most commonly used vesicles are large or giant unilamellar vesicles (LUV or GUV, respectively) composed of only a single bilayer, but also multilamellar vesicles (MLV) are used. The basic principles were first established in simple binary lipid mixtures, but recently

ternary mixtures which more closely mimic the composition of the cell plasma membrane have been used. The mixtures usually contain one lipid with a high melting temperature (Tm), one with a low Tm, and cholesterol. GUVs are probably the system closest to a cell membrane, because artifacts from a support are excluded. Still, cell membranes are asymmetric with different lipid compositions of the outer versus the inner leaflet, while the GUVs used so far were all symmetric.

Since maintaining an asymmetric lipid distribution is energy-consuming, perhaps by reconstituting lipid translocators into liposomes this drawback can be overcome in the future. Although model membrane systems produce very simplified pictures of cell membranes, there are many examples of a close correlation with experimental data obtained in living cells [14]. Ipsen et al. were the first to describe the formation of a liquid-ordered phase by cholesterol and saturated phospholipids [15,16]. This phase can coexist with other lipid phases, and its characteristics are described as follows: the translational order of lipid molecules within the liquid-ordered phase is similar to that in a fluid bilayer state, whereas the configurational order of the hydrocarbon chains compares more to that in a gel state. The formation of the liquid-ordered phase was attributed to the unique chemical nature of cholesterol (for a review, see [17]), but later it was shown that all natural sterols promote domain formation and that also

small amounts of ceramide (3%) can stabilize domains formed in vesicles [18]. Leventis and Silvius showed that the interaction of cholesterol with different lipid species is dependent on the nature of their hydrocarbon chains and, to a lesser extent, also on their headgroup. The interaction preference decreases with SM > PS > PC > PE and with increasing unsaturation of the acyl chains [19]. Whereas the kink in unsaturated hydrocarbon chains is likely to hinder tight packing with the flat sterol ring of cholesterol, the reason for the preferential interaction of cholesterol with SM is still a debated issue.

Deep Vein Thrombosis (scanning tutor)

Introduction

Although not one of the original six American College of Emergency Physicians indicated exams, evaluation for deep vein thrombosis (DVT) is one of the most useful exams for critical care physicians. There are approximately 250,000 new diagnoses of DVT per year and 50,000 deaths from thromboembolic disease annually (1,2). The estimated rate of propagation from DVT to pulmonary embolism ranges from 10% to 50% (1,2). Because the incidence of DVT is so high and because this disease is so prevalent in critical and acute care settings, the ability to rule in or rule out DVT at the bedside is a particularly powerful tool. The simplified compression technique described in this chapter evaluates for DVT at two anatomic sites of the lower extremity venous system. This protocol has been evaluated in multiple randomized controlled studies and has become a well-accepted protocol used for decision making in conjunction with clinical pre-test probability assessments (3–12)

Focused Questions for DVT Ultrasound
The questions for DVT ultrasound are as follows:

1. Does the common femoral vein fully compress?
2. Does the popliteal vein fully compress?

Anatomy
The anatomy of the lower extremity should be reviewed so the DVT compression ultrasound exam can be done properly. The ileac vein becomes the common femoral vein (CFV) as it leaves the pelvis. The most proximal tributary of the CFV is the greater saphenous vein (GSV) (Figure A). The common femoral then splits into the superficial and deep femoral in the proximal thigh – both of these vessels are part of the deep venous system despite their names. At the knee, the superficial femoral becomes the popliteal vein running in the posterior fossa of the knee joint and is joined by its tributaries, the tibial vein and peroneal vein . It is not surprising that clots, as shown by venography studies, seem to cluster at the branch points of the venous system. One common explanation is that the increased turbulent flow at these branch points produces increased wear and tear on the vessel walls, thus making these areas predisposed to clot formation. Data from these venography studies support the use of the simplified compression
technique because identification of clot in the popliteal vein or CFVshould identify any DVTs dentified by venography ; there were no cases in these initial studies where a DVT did not involve the popliteal vein, CFV, or both.

The Physics of Plasmas

The Physics of Plasmas provides a comprehensive introduction to the subject suitable for adoption as a self-contained text for courses at advanced undergraduate and graduate level. The extensive coverage of basic theory is illustrated with examples drawn from fusion, space and astrophysical plasmas. A particular strength of the book is its discussion of the various models used to describe plasma physics including particle orbit theory, fluid equations, ideal and resistive magnetohydrodynamics, wave equations and kinetic theory. The relationships between these distinct approaches are carefully explained giving the reader a firm grounding in the fundamentals, and developing this into an understanding of some of the more specialized topics. Throughout the text, there is an emphasis on the physical interpretation of plasma phenomena and exercises, designed to test the reader’s understanding at a variety of levels, are provided.

Students of physics and astronomy, engineering and applied mathematics will find a clear and rigorous explanation of the fundamental properties of plasmas with minimal mathematical formality. This book will also serve as a reference source for physicists and engineers engaged in research on aspects of fusion and space plasmas.
