This document summarizes the Bring Your Own Device (BYOD) market trends from 2013 to 2019. Some key points:
- The BYOD market is expected to grow significantly in coming years due to increased productivity from BYOD programs. Smartphones are currently the most widely used BYOD device.
- Adoption of BYOD is higher in emerging markets compared to mature markets, driven by lower corporate device provisioning and a greater comfort with mixing work and personal use.
- The financial services and healthcare sectors have been among the most active adopters of BYOD due to security requirements and productivity benefits.
- Top practices for BYOD policies include defining eligibility criteria, allowed device types, password protection standards,
The document provides an overview of the construction and infrastructure industry in Kenya. It outlines the objective to conduct research on the construction market in Kenya and opportunities in the insurance sector. The methodology involves secondary research using sources like company websites, reports, and news publications. It then covers Kenya's geo-political and macroeconomic environment, key sectors, investment rationale, and segments of the construction market like office, retail, industrial, and residential.
The electric vehicles market in India is currently small but expected to grow substantially over the next decade. Current market share is less than 0.1% but demand is estimated to increase 50 times by 2020 to 5 million units according to industry studies. The market is dominated by electric two-wheelers and led by Mahindra Reva in passenger electric cars. Growth will depend on continued government support through incentives coupled with advances in battery technology and industry investments. However, high prices, lack of charging infrastructure, and customer acceptance remain key challenges.
Dry eye disease, also known as keratoconjunctivitis sicca, is a condition caused by disturbances in the tear film that leads to an unstable tear film when the eye is open. It is a common reason for visits to ophthalmologists and affects about 75% of people over age 65, with the average patient being 54 years old. The disease involves inflammation that disrupts the normal feedback loop controlling tear production. Diagnosis involves tests like tear breakup time and Schirmer tests, and treatment focuses on replacing tears through artificial drops or increasing natural tear production through drugs like cyclosporine drops.
NATIONAL PROGRAMME FOR CONTROL OF BLINDNESSManoj Arockia
The National Programme for Control of Blindness in India was launched in 1976 with the goal of reducing blindness prevalence from 1.4% to 0.3%. Its key activities include expanding eye care services, establishing permanent infrastructure, and intensifying eye health education. It operates through a three-tier system at the peripheral, intermediate, and central levels. At each level it focuses on providing primary, secondary, and tertiary eye care services. It has also adopted strategic plans like 'Vision 2020: Right to Sight' to address specific blinding conditions and achieve its goal of eliminating avoidable blindness by 2020.
Vitamins are organic compounds that are required in small amounts to maintain normal health. The word "vitamin" comes from the Latin word "vita" meaning life. There are two types of vitamins - fat soluble (A, D, E, K) and water soluble (B complex, C). Vitamin A is important for vision, epithelial cell integrity, reproduction, resistance to infection, and bone remodeling. Symptoms of vitamin A deficiency include night blindness, dry eyes, and corneal damage.

jφ (r) • через точное положение частиц
B≠const.Выражения для n(r),
jφ (r) • через сохранение углового момента
Выражение для B`(r),β • через закон Био-Савара

Только частицы, траектории
которых проходят через кольцо

интеграл.
• При данном r максимально
далѐкая точка дающая вклад в
интеграл r0+ρ, и минимальная
r0-ρ.
• Будем считать, если частица
выходит за радиус R, то она
пропадает(абсорбция)
