Authors: Kovrigin Artur A. , Slesarev Mikhail Yu. 
Published: July 2021

Introduction. A landfill of solid industrial and domestic waste (LSIDW) is a source of negative impact on the environment. Although landfills have coverings, and they are equipped with engineering systems designated for the capturing and treatment of the biogas, LSIDW landfills still have a negative impact on subsurface and surface waters due to the spread of leachate. The purpose of this work is to obtain predictive data on changes in the hydrogeological characteristics of the territory of Salaryevo landfill, and to develop a simulation model to assess the application of technical solutions in the course of the landfill reclamation.
Materials and methods. Processing Modflow is the software designated for the 3D modeling of filtration and transportation of pollutants. An engineering report based on the engineering and environmental surveys, performed by JSC MosvodokanalNIIproekt in the Salaryevo landfill and its environs in 2017, served as the input data designated for a simulation model.
Results. Processing Modflow software allowed to consider three options of cutoff walls, tailored to this landfill. The installation of cutoff walls on the east and west sides of the landfill, to be performed with regard for the sorption function of the cutoff walls, is the most effective solution. The results have shown that the cutoff walls, installed to prevent the leachate from seeping, can potentially reduce the area, exposed to the impact, by 500 m.
Conclusions. It is recommended to install a cutoff wall in the west and a sorption curtain in the east in the course of recultivating Salaryevo landfill; this solution will ensure the containment of the leachate inside the landfill and prevent its spreading.

Informasi untuk mengetahui lokasi benda atau seseorang merupakan salah satu hal yang penting dalam kehidupan sehari-hari. Selama ini, teknologi Global Positioning System (GPS) dapat diandalkan ketika berada di luar ruangan. Namun, ketika di dalam ruangan, GPS akan sulit menjangkau secara spesifik area bangunan. Dengan memanfaatkan teknologi Light Fidelity (Li-Fi), Indoor Positioning System (IPS) akan lebih mudah dilakukan dan mempunyai keunggulan dari segi akurasi dan efisiensi energi. Tetapi, jika dikaitkan dengan IPS, pemasangan lampu Light Emitting Diode (LED) perlu diperhatikan geometri pemasangannya. Penelitian ini membahas akurasi IPS pada Li-Fi apabila dengan berbagai bentuk geometri dan lokasi pemasangan lampu LED yang berbeda-beda. Teknik positioning Received Signal Strength (RSS) digunakan dengan mengambil kuat daya terima sebagai estimasi suatu jarak. Dengan membandingkan masing-masing bentuk geometri, maka didapatkan data konfigurasi terbaik untuk implementasi IPS. Hasil penelitian menunjukkan bahwa perbedaan jumlah lampu LED dan bentuk geometri akan berpengaruh terhadap akurasi positioning. Hasil menunjukkan bahwa geometri segi enam memiliki rata-rata error yang lebih kecil dibandingkan geometri yang lain, yakni sebesar 1,53×10?05m. Semakin banyak lampu LED atau poin referensi dengan rentang jarak lampu yang lebih rapat, maka dapat menghasilkan positioning yang lebih baik.

В статье обосновывается большое значение копирования произведений монументального искусства Древней Руси. Это позволяет сохранить изображения пусть даже в копиях, а в процессе копирования не только подробно изучить технологические и содержательные стороны фресковых циклов, но и, по мнению автора, формирует мировоззрение, дает возможность целостнее оценить духовный мир мастеров прошлого. Само копирование должно носить не фрагментарный характер, а комплексно охватывать всю систему росписей храма. Высококачественные копии фресок могут быть интересными экспонатами выставок и должны храниться как произведения искусства.
The article substantiates the great importance of copying works of monumental art of Ancient Rus. This allows you to save images even in copies, allows during the copy process, not only to study in detail the technological and content side of fresco cycles, but, according to the author, forms the world, allows integrity to assess spiritual world of the masters of the past. The copy itself must not be fragmented, but to comprehensively cover all of the murals of the temple. High-quality copies of frescoes can be interesting exhibits in exhibitions and should be kept as works of art.

Authors: McDonald Jordanos T. , Trenholm Jill 
Published: July 2021

Background In 2015 alone, 5,9 million children under the age of five died. In an attempt to reduce child mortality in Eritrea, the government implemented community- based child health interventions by community health workers (CHWs). Despite progress, challenges remain. In Eritrea, few studies have examined CHWs and community perceptions of child health interventions. The aim of this study was to explore the perceptions of CHWs regarding benefits and challenges of community-based child health interventions in the Maekel region in Eritrea. Methods An explorative qualitative study was conducted employing focus group discussions. Data was analyzed using qualitative content analysis. Results The CHWs reported positive aspects such as easier access to health services, generated relationships and support and opportunities to give back to the community. Perceived challenges were: constraints in delivering services, resources and supervision, inadequate knowledge and awareness and juggling multiple roles with no pay. The ministry of health (MoH) in Eritrea prioritizes reducing child mortality but, is still in the process of building and stabilizing the healthcare system. The biggest challenge is to incorporate community level Integrated Management of Childhood Illnesses and Case Management (C-IMCI/iCCM), involving communities, families and CHWs into the current system of limited resources. Conclusions This study indicates the importance of focusing on identifying solutions to the challenges the CHWs faces and understanding factors associated with CHWs motivation. This with the hope of better effectiveness and sustainability of the C-IMCI/iCCM program.

Dengan adanya lembaga reksa dana di Indonesia diharapkan dapat menciptakan presepsi baru bahwa untuk berinvestasi di pasar modal sangat mudah dan diperlukan modal yang tidak terlalu besar. Reksa dana merupakan alternatif investasi bagi masyarakat Indonesia yang sebagian besar penduduknya pemeluk agama islam terbanyak di dunia dan kesempatan untuk mendapatkan hasil investasi yang lebih baik dalam jangka waktu tertentu. Reksa dana syariah tidak menginvestasikan saham-saham dari perusahaan yang pengelolaan atau produknya bertentangan dengan syariah Islam seperti alkohol, rokok, perjudian, pornografi, dan hal-hal lainnya yang diharamkan dalam syariat Islam. Hal yang membedakan antara reksa dana konvensional dengan reksa dana syariah adalah adanya proses screening dan cleansing.
