A Gantt chart is a type of bar chart that illustrates a project schedule. Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project. Terminal elements and summary elements comprise the work breakdown structure of the project. Some Gantt charts also show the dependency (i.e, precedence network) relationships between activities. Gantt charts can be used to show current schedule status using percent-complete shadings and a vertical "TODAY" line as shown here.

Sample project s Curve
The term S-Curve can also be used to indicate an S shaped chart resulting from a cumulative likelihood distribution. In this function, an S-Curve is a tool of quantitative risk analysis which project management would use to determine the possible dangers of any given course of action.
This term is defined in the 3rd and the 4th edition of the PMBOK.
The S Curve is a well known project management tool and it consists in "a display of cumulative costs, labour hours or other quantities plotted against time".The name derives from the S-like shape of the curve, flatter at the beginning and end and steeper in the middle, because this is the way most of the projects look like.
The S curve can be considered as an indicator and it's used for many applications related to project management such as: target, baseline, cost, time etc. That's why there is a variety of S Curves such as:
-Cost versus Time S Curve;(appropriate for projects that contain labour and non-labour tasks).
-Target S Curve;(This S Curve reflects the ideal progress of the project if all tasks are completed as currently scheduled)
-Value and Percentage S Curves;(Percentage S Curves are useful for calculating the project's actual percentage complete)
-Actual S Curve;(This S Curve reflects the actual progress of the project to date)
In order to be able to generate a S Curve, A Baseline and Production Schedule are necessary because they contain important information for each task: -the Baseline - contains information about Actual Start date and finish date.
-The Baseline - can also contain information about Man Hours and costs.
-The Production Schedule contains information about the actual percentage complete.
There are some software scheduling packages that generate automatically S Curves. For example MS Project does not have this possibility so a third party software application is needed to process the Baseline and Production Schedule data and generate the needed S Curve.( for example S Curve Generator that integrates with MS EXcel to generate S Curves).
It was developed in the 1950s by the Dupont Corporation at about the same time that General Dynamics and the US Navy were developing the Program Evaluation and Review Technique (PERT) Today, it is commonly used with all forms of projects, including construction, software development, research projects, product development, engineering, and plant maintenance, among others. Any project with interdependent activities can apply this method of scheduling.
The essential technique for using CPM is to construct a model of the project that includes the following:
- A list of all activities required to complete the project (also known as Work breakdown structure),
- The time (duration) that each activity will take to completion, and
- The dependencies between the activities.
Using these values, CPM calculates the longest path of planned activities to the end of the project, and the earliest and latest that each activity can start and finish without making the project longer. This process determines which activities are "critical" (i.e., on the longest path) and which have "total float" (i.e., can be delayed without making the project longer). In project management, a critical path is the sequence of project network activities which add up to the longest overall duration. This determines the shortest time possible to complete the project. Any delay of an activity on the critical path directly impacts the planned project completion date (i.e. there is no float on the critical path). A project can have several, parallel, near critical paths. An additional parallel path through the network with the total durations shorter than the critical path is called a sub-critical or non-critical path.
These results allow managers to prioritize activities for the effective management of project completion, and to shorten the planned critical path of a project by pruning critical path activities, by "fast tracking" (i.e., performing more activities in parallel), and/or by "crashing the critical path" (i.e., shortening the durations of critical path activities by adding resources).
A Work Breakdown Structure is a results-oriented family tree that captures all the work of a project in an organized way. It is often portrayed graphically as a hierarchical tree, however, it can also be a tabular list of "element" categories and tasks or the indented task list that appears in your Gantt chart schedule. As a very simple example, Figure 1 shows a WBS for a hypothetical banquet.

In healthy cells and tissue, more than 90% of the total glutathione pool is in the reduced form (GSH) and less than 10% exists in the disulfide form (GSSG). An increased GSSG-to-GSH ratio is considered indicative of oxidative stress.
"Glutathione is a very interesting, very small molecule that's [produced by the body and] found in every cell," says Gustavo Bounous, MD, director of research and development at Immunotec and a retired professor of surgery at McGill University in Montreal, Canada. "It's the [body's] most important antioxidant because it's within the cell."
Antioxidants -- the most well known of which are vitamins C and E -- are important for good health because they neutralize free radicals, which can build up in cells and cause damage. Because glutathione exists within the cells, it is in a prime position to neutralize free radicals. It also has potentially widespread health benefits because it can be found in all types of cells, including the cells of the immune system, whose job is to fight disease.
Glutathione occurs naturally in many foods, and people who eat well probably have enough in their diets, says Dean Jones, PhD, professor of biochemistry and director of nutritional health sciences at Emory University in Atlanta. Those with diets high in fresh fruits and vegetables and freshly prepared meats are most likely just fine. On the other hand, those with poor diets may get too little.

In the morning, one can buy varieties of fish and seafoods at reasonable prices. During low-tides, you will see several fishermen hunting for different types of edible shells, crabs, and octopuses on the parts of the beach where mangrove trees grow abundantly.

The existence of Catanauan as a pueblo (town) was first recorded in the map of Father Pedro Murillo dated on 1734. The petitio dated 1685 of Bishop Andres Gonzales of Nueva Caceres, Naga City requesting the king of Spain to have Masbater and the Pueblo of Catanauan assigned to Recollect Order was reflective of the early creation of Catanauan. The recognized foundation year of the Municipality was 1713 called as NABATASAN.
In the late 18th and 19th century, there were frequent Moro raids. These occurrences prompted the people to construct two small stone forts or watch towers (MAGKATANAWAN) mounted with artillery. Santa Maria watch tower was located at Lot 21 psc-2 near the present wharf is located. Castillo watch tower stood at the intersection of present Rizal and Boncan Street. Hence,the name CATANAUAN was so derived.BoliNg-BoliNg
Umagang Kay Ganda anchor Winne Cordero was in Catanauan and had a live interview with Ms. Malou Baticulon on Uraro Cookies, Mrs. Apura and Mrs. Cadiz regarding facts on Boling-boling Festival and a message from Mayor RamonOrfanel.
The program also featured Catanauan products including wood/bamboo furnitures, agricultual produce, herbal products, uraro cookies, house accessories and banana chips. There was also a short special coverage in a fish sanctuary project under-going at Barangay Ajos which is headed by Mr. Gabriel Tan. The project, if becomes successful, would help the barangay fishermen because they would be able to catch 10-50kgs of maya-maya,lapu-lapu, talimutok and other fishes in the area. Mr. Gabriel Tan is hoping that the project could become a model one in town.
This year's theme of Boling-boling Festival is "Tuklasin sa pusod ng Bondoc Peninsula, Isang Bayan, Isang Kultura, Isang Musika.Watch Catanauan at Umagang Kay Ganda: * Take note that it is only part of the whole program, so please set the playing time to the following to directly access the Catanauan live coverage.
