Phosphorous metabolism involves the following key points:
- Phosphorous makes up 80% of bones and teeth and 10% of muscles in the human body. The daily requirement is 500 mg. Dietary sources include milk, cereals, nuts, and meat.
- Serum phosphorous concentration in adults is normally 3-4 mg/dl and in children is 5-6 mg/dl. Whole blood phosphate is 40 mg/dl. Levels decrease in hyperthyroidism and rickets.
- Phosphorous exists in the body in free ionic form, complexed with other ions, and protein-bound. It is an integral part of biomolecules and is involved in ribonucleotide

Technical communication of automation control system in water treatment planthunypink
This paper presents technical communication of automation industry which describes the technical issues of
automation control system in operation development, improving management level and high efficiency process in water treatment system. Today’s water treatment plants are applied for water conservancy projects, emerged by the technology of automation control system is to ensure safe, continues, high quality water supply to municipal and for multi-purpose usage. Along with automation technology, computer technology, network communication development, advanced water treatment monitoring system is realized in Nantong pengyoa water purification plant. The Nantong pengyoa water purification plant has an important beneficial industry relationship to People’s Republic of China improving living status and environment condition mainly expounds the water supply, to build well-off society, comparatively improving the labor production growth & level of implementation of targets as well as high water quality requirements. In this paper, it develops the task and tells the technical solutions of water treatment plant which has been centralized in fully automated operation in some developed industries since many years. And also append short description of its current practices such as networking, and real-time monitoring control, composition & structure, process flow and automatic process control which are performed in water treatment plants to achieve high efficiency in quality of productivity.
The Mental Leaps @ericsson 3G - Innovative Ways of Working TogetherErik Schön
In this session, I share how we made three very important mental leaps to make the transition to Agile and Lean ”stick” including concrete examples of what we have done at Ericsson 3G.
Leap #1: From Methods & Tools to Principles & Mindset
Tools and methods can work in some contexts and not in others. If you have your own principles and mindset, then you can adapt or create your own methods and tools that fit your context. When realizing this, we made a mental leap from a focus on methods and tools to a focus on principles and mindset.
Leap #2: From Resource Efficiency to Flow Efficiency
With a need reduce both costs and time-to-market we were looking for alternatives to “resource efficiency” focus (keeping people and equipment fully utilized at all times). We realized that our ability to innovate around state-of-the art algorithms for optimizing packet data flow in mobile radio networks is also applicable for our product development processes. We made a mental leap from “resource efficiency” to “flow efficiency”, i e a focus on keeping work items moving through the process without waiting times, delivering value as quickly as possible
Leap #3: From Scattered Experiences to Continuous Innovation
We were solving problems as they occurred using task forces in fire-fighting mode, lacking corporate memory and a common direction. By creating a shared direction and a common purpose around the need to improve, we made the leap from scattered experiences to a culture of continuous innovation.
Ericsson is the driving force behind the Networked Society - a world leader in communications technology and services. Our long-term relationships with every major telecom operator in the world allow people, business and society to fulfill their potential and create a more sustainable future. With approximately 115,000 professionals and customers in 180 countries, we combine global scale with technology and services leadership. We support networks that connect more than 2.5 billion subscribers. Forty percent of the world's mobile traffic is carried over Ericsson networks. Net sales in 2014 were EUR 23.4 billion.

The college has been operating since 1963 and offers qualifications in over 15 fields including hospitality, health care, technology, and construction. It aims to ensure all students can find employment, further education, or rehabilitation through cooperation with local employers and services like its One-Stop Guidance Center for young adults.
- Havukoski School is undergoing renovations from 2018-2019 with a budget of 9.5 million euros to update its 30 year old building.
- The renovations aim to create a more extensive learning environment with open and flexible learning areas to support new pedagogical approaches.
- Teachers, students, and parents have provided input into the planning process through workshops and meetings with architects.
- The renovated school will feature both open learning spaces and traditional classrooms, with an emphasis on technology, well-being, and security.

Latvia is a Baltic country with a long history and rich culture. Some of the most important symbols of Latvia's independence include the Freedom Monument in Riga and the country's flag, one of the oldest in the world. Latvia celebrates its independence day on November 18th. Latvian culture is expressed through traditional folk dresses, Midsummer festivals, song and dance celebrations, and historical sites throughout the country in cities like Riga, Jelgava, and Stāmerienas. Latvia also takes pride in preserving its natural environments and being a center for sports like hockey, basketball, and football.
