1 Answer

Answer :

The Distribution Antenna System (DAS) is a series of radio heads which is surrounded by the target locations which exists with a cellular coverage, network connections (radio units, donor antenna, bi-directional amplifiers, and antennas nodes) and services (pre and post services) based applications. It is connected wirelessly with carrier, enterprises and neutral-host technology. The main purpose is to provide coverage in the real-time condition, to improve performance and others. The distributed antenna systems (DAS) offer a wide range of applications in public venue, hospitality, healthcare, education, enterprises, retail and airports & transportation. Global distributed antenna system market is expected to reach million by 2026 and is projected to register a healthy CAGR of 10.5% in the forecast period of 2019 to 2026. Competitive Analysis: Global Distributed Antenna System (DAS) Market Some of the major players operating in the Global distributed antenna system market are COMMSCOPE, Corning Incorporated , Cobham Wireless, Comba Telecom Systems Holdings Ltd., SOLiD, ATC IP LLC, AT&T, Boingo Wireless, Inc. , Dali Wireless, Zinwave, Bird Technologies, HUBER+SUHNER, JMA Wireless, Westell Technologies, Inc. , GALTRONICS, BTI wireless, Advanced RF technologies, Betacom Incorporated, CONNECTIVITY WIRELSS SOLUTION and among others.

Answer: e The role of nutritional support in the cancer patient remains an important component of overall therapy. Preoperative nutritional support should be given only to those patients who do not require an emergency operation and who have severe weight loss (> 15% of pre-illness body weight) and a serum albumen < 2.9 mg%. Preoperative nutrition (enteral or parenteral) should not be given for longer than 7 to 10 days. Enteral nutrition is always the preferred route of feeding cancer patients if the GI tract is functional. There are several benefits of using the bowel lumen for nutrient delivery. The trophic effects of enteral feeding on small bowel mucosa have been well described. The integrity of the mucosal lining is maintained and it may provide an effective barrier to intraluminal
