GERAKAN 500 MASKER DAN HANDSCOON PEMBERIAN MASKER DAN HANDSCOON UNTUK KLINIK MUHAMMADIYAH CERME DEMI PENGOPTIMALAN PELAYANAN PASIEN DAN PELINDUNGAN DIRI BAGI TENAGA KESEHATAN

Klinik Muhammadiyah Cerme merupakan salah satu klinik satelit RS Muhammadiyah Gresik, yang berada di Desa Ngembung, Cerme Gresik, yang menjadi klinik Pratama bagi warga di Desa Ngembung dan sekitarnya. Klinik ini telah berdiri 3 tahun lebih sejak diresmikan pada 8 Februari 2017. Sampai tahun 2020, Klinik ini telah dilengkapi oleh IGD, laboratorium, Poli Gigi dan Ruang rawat inap. Sebagaimana klinik yang baru awal berdiri, beberapa pembenahan dan sosialisasi perlu dilakukan untuk menarik warga setempat berobat di klinik ini. Namun, sejak pandemi COVID-19 dimulai, klinik ini menjadi semakin sepi. Masyarakat lebih memilih beristirahat di rumah apabila sakit. Hal itu berdampak pada finansial klinik ini. Salah satunya pada penyediaannya perlengkapan APD. Apalagi ditambah dengan stok dan harga APD seperti masker dan handscoon yang terbatas dan semakin mahal. Padahal, masker dan handscoon adalah APD paling utama dalam menangani pasien di tengah pandemi COVID-19 ini. Oleh karena itu, dalam rangka mengimplementasikan salah satu Tri Dharma perguruan tinggi, yaitu pengabdian masyarakat, Tim Fakultas Teknik Universitas Muhammadiyah Gresik (UMG) mengadakan kegiatan pembagian alat pelindung diri, antara lain masker, sarung tangan dan handscoon, untuk tenaga kesehatan di rumah sakit di kecamatan cerme. Pengabdian masyarakat  ini bertujuan untuk mengurangi beban tenaga kesehatan yang diakibatkan COVID-19 dan juga sebagai bentuk kepedulian Fakultas teknik UMG dalam mendukung tenaga kesehatan dalam melayani masyarakat. Pembagian APD ini terdiri dari 500 masker bedah, 500 buah handscoon dan 10 buah face shield. Dan Tema  Pengabdian Masyarakat kali ini adalah “Bersama UMG kita Lawan Covid-19”

Two-dimensional Vesicle dynamics under shear flow: effect of confinement

Dynamics of a single vesicle under shear flow between two parallel plates is studied using two-dimensional lattice-Boltzmann simulations. We first present how we adapted the lattice-Boltzmann method to simulate vesicle dynamics, using an approach known from the immersed boundary method. The fluid flow is computed on an Eulerian regular fixed mesh while the location of the vesicle membrane is tracked by a Lagrangian moving mesh. As benchmarking tests, the known vesicle equilibrium shapes in a fluid at rest are found and the dynamical behavior of a vesicle under simple shear flow is being reproduced. Further, we focus on investigating the effect of the confinement on the dynamics, a question that has received little attention so far. In particular, we study how the vesicle steady inclination angle in the tank-treading regime depends on the degree of confinement. The influence of the confinement on the effective viscosity of the composite fluid is also analyzed. At a given reduced volume (the swelling degree) of a vesicle we find that both the inclination angle, and the membrane tank-treading velocity decrease with increasing confinement. At sufficiently large degree of confinement the tank-treading velocity exhibits a non-monotonous dependence on the reduced volume and the effective viscosity shows a nonlinear behavior.Comment: 12 pages, 8 figure

A quantitative theory of current-induced step bunching on Si(111)

We use a one-dimensional step model to study quantitatively the growth of step bunches on Si(111) surfaces induced by a direct heating current. Parameters in the model are fixed from experimental measurements near 900 deg C under the assumption that there is local mass transport through surface diffusion and that step motion is limited by the attachment rate of adatoms to step edges. The direct heating current is treated as an external driving force acting on each adatom. Numerical calculations show both qualitative and quantitative agreement with experiment. A force in the step down direction will destabilize the uniform step train towards step bunching. The average size of the step bunches grows with electromigration time as t^beta, with beta = 0.5, in agreement with experiment and with an analytical treatment of the steady states. The model is extended to include the effect of direct hopping of adatoms between different terraces. Monte-Carlo simulations of a solid-on-solid model, using physically motivated assumptions about the dynamics of surface diffusion and attachment at step edges, are carried out to study two dimensional features that are left out of the present step model and to test its validity. These simulations give much better agreement with experiment than previous work. We find a new step bending instability when the driving force is along the step edge direction. This instability causes the formation of step bunches and antisteps that is similar to that observed in experiment.Comment: 11 pages, 7 figure

Pharmacogenomics in the UK National Health Service: opportunities and challenges

There is increasing interest in pharmacogenomics. However, it is also widely acknowledged that implementation of pharmacogenomics into clinical practice has been slow. Implementation is being undertaken in many centres in the US, but this is not nationwide and often focused on highly specialised academic centres, driven by champions. To date, there has been no implementation on a whole country basis. The UK National Health Service (NHS) is a single integrated healthcare system, which provides free care to all patients at the point of need. Recently, there has been a drive to implement genomic medicine into the NHS, largely spurred on by the success of the 100,000 genomes project. This represents an unprecedented opportunity to implement pharmacogenomics for over 60 million people. In order to discuss the potential for implementing pharmacogenomics into the NHS, the UK Pharmacogenetics and Stratified Medicine Network, NHS England and Genomics England invited experts from academia, the healthcare sector, industry and patient representatives to come together to discuss the opportunities and challenges1. This report highlights the discussions of the workshop with the aim of providing an overview of the issues that need to be considered to enable pharmacogenomic medicine to become mainstream within the NHS

Micro-Capsules in Shear Flow

This paper deals with flow-induced shape transitions of elastic capsules. The state of the art concerning both theory and experiments is briefly reviewed starting with dynamically induced small deformation of initially spherical capsules and the formation of wrinkles on polymerized membranes. Initially non-spherical capsules show tumbling and tank-treading motion in shear flow. Theoretical descriptions of the transition between these two types of motion assuming a fixed shape are at variance with the full capsule dynamics obtained numerically. To resolve the discrepancy, we expand the exact equations of motion for small deformations and find that shape changes play a dominant role. We classify the dynamical phase transitions and obtain numerical and analytical results for the phase boundaries as a function of viscosity contrast, shear and elongational flow rate. We conclude with perspectives on timedependent flow, on shear-induced unbinding from surfaces, on the role of thermal fluctuations, and on applying the concepts of stochastic thermodynamics to these systems.Comment: 34 pages, 15 figure
