Reducing Occupational Sitting Time and Improving Worker Health: The Take-a-Stand Project, 2011
Fortunately, MS Project fixed a lot of these issues by adding inactive tasks to the Microsoft Project release. The inactive tasks feature allows project managers to remove tasks from the schedule while recognizing the task existed in the original plan. The figure below depicts 5 . - [Voiceover] Hi, I'm Bonnie Biafore. Welcome to Project Essential Training. Microsoft Project is one of the most widely used project scheduling and management programs. I'll show you how to get up to speed with this powerful program and how to get the most out of it. We'll explore setting up all kinds of project tasks like work tasks, summary tasks, milestones, and recurring tasks.
In some organizations, encrypting data is mandatory, and as you might mss, it can exact a performance how to set a baseline in ms project 2010. Here is an example of SQL Server error log entry showing what happens if you start the service with an account other than the one used to encrypt the files:.
How much it will affect speed is a tough to measure as there are so many factors to consider. For example:. The tests were repeated five times, with the average figures shown below. No other user or application was running during the tests. The databases were identical in terms of their size, recovery model, collation and other basic settings.
Before beginning the tests, What is bls certification in the medical field tested to be sure that encryption was working.
This can be done by typing the following at the command line:. The results above indicate that encryption is on and that there are two existing files that are encrypted. And before each test, I ran the following code in order to clear out the memory buffer and to force a checkpoint. Your email address will not be published.

Understand the types, formats, and components of Project views
Collecting baseline data may be important if we want to be able to show outcomes or conduct an impact assessment after the conclusion of our project. If we want to show the impact of our project, or the changes in people’s attitudes, behaviors, or competencies, then we may need a baseline to compare to. Note: To subtract seven days from a specified date, the following formula works correctly on Project Professional ProjDateAdd("9/24/", "-7d").However, when you run the same formula on Project Server , the result is 9/24/, not 9/17/ For formulas that work consistently on Project Professional and Project Server , you should avoid negative parameters for the. Project provides different types of views that present project information by using different formats and components, such as tables, filters, groups, and details. It is important to understand the difference between these properties. Types. Project uses three types of views: task views, resource views, and assignment views. Formats.
The Soyuz succeeded the Voskhod spacecraft and was originally built as part of the Soviet crewed lunar programs. The Soyuz is heavily used in the ISS programme. The first Soyuz flight was uncrewed and started on 28 November The first Soyuz mission with a crew, Soyuz 1 , launched on 23 April but ended with a crash due to a parachute failure, killing cosmonaut Vladimir Komarov. The following flight was uncrewed. Soyuz 3 , launched on 26 October , became the program's first successful crewed mission.
The only other flight to suffer a fatal accident, Soyuz 11 , killed its crew of three when the cabin depressurized prematurely just before reentry. At least one Soyuz spacecraft is docked to ISS at all times for use as an escape craft in the event of an emergency. The spacecraft is intended to be replaced by the six-person Orel spacecraft.
The orbital and service modules are single-use and are destroyed upon reentry in the atmosphere. Though this might seem wasteful, it reduces the amount of heat shielding required for reentry, saving mass compared to designs containing all of the living space and life support in a single capsule.
This allows smaller rockets to launch the spacecraft or can be used to increase the habitable space available to the crew 6. The orbital and reentry portions are habitable living space, with the service module containing the fuel, main engines and instrumentation. The Soyuz is not reusable; it is expendable.
A new Soyuz spacecraft must be made for every mission. Soyuz can carry up to three crew members and provide life support for about 30 person days. The atmosphere is regenerated through potassium superoxide KO 2 cylinders, which absorb most of the carbon dioxide CO 2 and water produced by the crew and regenerates the oxygen , and lithium hydroxide LiOH cylinders which absorb leftover CO 2. It has an automatic docking system.
The ship can be operated automatically, or by a pilot independently of ground control. The Vostok spacecraft utilized an ejector seat to bail out the cosmonaut in the event of a low-altitude launch failure, as well as during reentry, however it would probably have been ineffective in the first 20 seconds after liftoff when the altitude would be too low for the parachute to deploy.
This included developing a complex sensing system to monitor various launch vehicle parameters and trigger an abort if a booster malfunction occurred. Based on data from R-7 launches over the years, engineers developed a list of the most likely failure modes for the vehicle and could narrow down abort conditions to premature separation of a strap-on booster, low engine thrust, loss of combustion chamber pressure, or loss of booster guidance.
Since it turned out to be almost impossible to separate the entire payload shroud from the Soyuz service module cleanly, the decision was made to have the shroud split between the service module and descent module during an abort. Four folding stabilizers were added to improve aerodynamic stability during ascent. Two test runs of the SAS were carried out in — The basic design of the SAS has remained almost unchanged in 50 years of use and all Soyuz launches carry it.
The only modification was in when the aerodynamic fairing over the SAS motor nozzles was removed for weight-saving reasons as the redesigned Soyuz 7K-T spacecraft carried extra life support equipment.
The uncrewed Progress resupply ferry has a dummy escape tower and removes the stabilizer fins from the payload shroud. The failure was aborted after escape tower jettison.
In , Soyuz Ta's SAS successfully rescued the cosmonauts from an on-pad fire and explosion of the launch vehicle. It houses all the equipment that will not be needed for reentry, such as experiments, cameras or cargo.
The module also contains a toilet, docking avionics and communications gear. Internal volume is 6 m 3 cu ft , living space 5 m 3 cu ft. On the latest Soyuz versions since Soyuz TM , a small window was introduced, providing the crew with a forward view. A hatch between it and the descent module can be closed so as to isolate it to act as an airlock if needed, crew members exiting through its side port near the descent module. On the launch pad, the crew enter the spacecraft through this port.
This separation also lets the orbital module be customized to the mission with less risk to the life-critical descent module. The convention of orientation in a micro-g environment differs from that of the descent module, as crew members stand or sit with their heads to the docking port.
Also the rescue of the crew whilst on the launch pad or with the SAS system is complicated because of the orbital module. Separation of the orbital module is critical for a safe landing; without separation of the orbital module, it is not possible for the crew to survive landing in the descent module. This is because the orbital module would interfere with proper deployment of the descent module's parachutes, and the extra mass exceeds the capability of the main parachute and braking engines to provide a safe soft landing speed.
In view of this, the orbital module was separated before the ignition of the return engine until the late s. This guaranteed that the descent module and orbital module would be separated before the descent module was placed in a reentry trajectory. However, after the problematic landing of Soyuz TM-5 in September this procedure was changed and the orbital module is now separated after the return maneuver.
This change was made as the TM-5 crew could not deorbit for 24 hours after they jettisoned their orbital module, which contained their sanitation facilities and the docking collar needed to attach to Mir.
The risk of not being able to separate the orbital module is effectively judged to be less than the risk of needing the facilities in it, including the toilet, following a failed deorbit. Half of the descent module is covered by a heat-resistant covering to protect it during reentry ; this half faces forward during reentry. It is slowed initially by the atmosphere, then by a braking parachute, followed by the main parachute which slows the craft for landing.
At one meter above the ground, solid-fuel braking engines mounted behind the heat shield are fired to give a soft landing. One of the design requirements for the descent module was for it to have the highest possible volumetric efficiency internal volume divided by hull area. The best shape for this is a sphere — as the pioneering Vostok spacecraft's descent module used — but such a shape can provide no lift, which results in a purely ballistic reentry.
Ballistic reentries are hard on the occupants due to high deceleration and cannot be steered beyond their initial deorbit burn. That is why it was decided to go with the "headlight" shape that the Soyuz uses — a hemispherical forward area joined by a barely angled seven degrees conical section to a classic spherical section heat shield.
This shape allows a small amount of lift to be generated due to the unequal weight distribution. The nickname was thought up at a time when nearly every headlight was circular. The small dimensions of the descent module led to it having only two-man crews after the death of the Soyuz 11 crew. The later Soyuz T spacecraft solved this issue. Internal volume of Soyuz SA is 4 m 3 cu ft ; 2.
It has a pressurized container shaped like a bulging can instrumentation compartment, priborniy otsek that contains systems for temperature control, electric power supply, long-range radio communications , radio telemetry , and instruments for orientation and control.
A non-pressurized part of the Service Module propulsion compartment, agregatniy otsek contains the main engine and a liquid-fuelled propulsion system for maneuvering in orbit and initiating the descent back to Earth. The ship also has a system of low-thrust engines for orientation, attached to the intermediate compartment perekhodnoi otsek. Outside the Service Module are the sensors for the orientation system and the solar array, which is oriented towards the Sun by rotating the ship.
An incomplete separation between the Service and reentry modules led to emergency situations during Soyuz 5 , Soyuz TMA and Soyuz TMA , which led to an incorrect reentry orientation crew ingress hatch first. The failure of several explosive bolts did not cut the connection between the service and reentry modules on the latter two flights. The Soyuz uses a method similar to the United States Apollo command and service module to deorbit itself.
The spacecraft is turned engine-forward and the main engine is fired for deorbiting on the far side of Earth ahead of its planned landing site. This requires the least propellant for reentry ; the spacecraft travels on an elliptical Hohmann transfer orbit to the entry interface point where atmospheric drag slows it enough to fall out of orbit. Early Soyuz spacecraft would then have the service and orbital modules detach simultaneously from the descent module. As they are connected by tubing and electrical cables to the descent module, this would aid in their separation and avoid having the descent module alter its orientation.
Since the Soyuz TM-5 landing issue, the orbital module is once again detached only after the reentry firing, which led to but did not cause emergency situations of Soyuz TMA and TMA The orbital module cannot remain in orbit as an addition to a space station, as the airlock hatch between the orbital and reentry modules is a part of the reentry module, and the orbital module therefore depressurizes after separation.
Reentry firing is usually done on the "dawn" side of the Earth, so that the spacecraft can be seen by recovery helicopters as it descends in the evening twilight, illuminated by the Sun when it is above the shadow of the Earth.
This is in contrast to the early United States crewed spacecraft, which splashed down in the ocean. The Soyuz spacecraft has been the subject of continuous evolution since the early s. Thus several different versions, proposals and projects exist.
Sergei Korolev initially promoted the Soyuz A-B-V circumlunar complex 7K-9KK concept also known as L1 in which a two-man craft Soyuz 7K would rendezvous with other components 9K and 11K in Earth orbit to assemble a lunar excursion vehicle, the components being delivered by the proven R-7 rocket.
The crewed Soyuz spacecraft can be classified into design generations. Soyuz 1 through Soyuz 11 — were first-generation vehicles, carrying a crew of up to three without spacesuits and distinguished from those following by their bent solar panels and their use of the Igla automatic docking navigation system, which required special radar antennas. The probe and drogue docking system permitted internal transfer of cosmonauts from the Soyuz to the station. The Soyuz 7K-L1 was designed to launch a crew from the Earth to circle the Moon , and was the primary hope for a Soviet circumlunar flight.
It had several test flights in the Zond program from — Zond 4 to Zond 8 , which produced multiple failures in the 7K-L1's reentry systems. The remaining 7K-L1s were scrapped. Soyuz 1 was plagued with technical issues, and cosmonaut Vladimir Komarov was killed when the spacecraft crashed during its return to Earth. This was the first in-flight fatality in the history of spaceflight.
It was designed for space station flights and had a docking port that allowed internal transfer between spacecraft. Soyuz 11 , the second flight, depressurized upon reentry, killing its three-man crew. It was developed out of the military Soyuz concepts studied in previous years and was capable of carrying 2 cosmonauts with Sokol space suits after the Soyuz 11 accident. Several models were planned, but none actually flew in space.
Soyuz 7K-TM was the spacecraft used in the Apollo-Soyuz Test Project in , which saw the first and only docking of a Soyuz spacecraft with an Apollo command and service module. It was also flown in for the Earth-science mission, Soyuz Soyuz 7K-TM served as a technological bridge to the third generation.
It could carry a crew of three, now wearing spacesuits. It is also the first expendable vehicle to feature " glass cockpit " technology. Soyuz-TMA looks identical to a Soyuz-TM spacecraft on the outside, but interior differences allow it to accommodate taller occupants with new adjustable crew couches.
The Soyuz TMA-M was an upgrade of the baseline Soyuz-TMA, using a new computer, digital interior displays, updated docking equipment, and the vehicle's total mass was reduced by 70 kilograms. The mission used a new six-hour rendezvous, faster than the previous Soyuz launches, which had, since , taken two days. Soyuz MS is the final planned upgrade of the Soyuz spacecraft.
Its maiden flight was in July with mission Soyuz MS Major changes include:  .
