Project de-escalation refers to closing a project before completion. There exist signs which warn managers on the need for project de-escalation. Foremost is when the project demands more money than the budgeted amount to keep it going. Nonetheless, that is a sign that all may not be well with the implementation of the project and it may lead to huge loss. In such a case, the management may decide to just stop the project. Second is the change in the general mood of the project’s management. When project managers face hurdles which may necessitate de-escalation, they will most ...

Central Issue:

The question to be answered is how Mattel should respond from a strategic standpoint in light of a product recall that involved unsafe toys that were made in China. While the use of offshoring of labor is pervasive in the industry that Mattel works in, there are indeed other options and having “tainted” toys and other products that are used primarily, if not solely, by children is a huge problem for Mattel from a reputation and liability standpoint.

Recommended Course of Action:

Mattel is in a precarious position in that having the toys made in the United States or in other fully developed ...

Heart is one of the most important part of the body. It performs many vital functions that are essential for life. Without the functioning of heart there is no life. Heart is also considered as the pumping organ of the body. The main function of heart is to pump the blood throughout the body ("The Heart (Human Anatomy): Picture, Definition, Location In The Body, And Heart Problems"). Inside the body blood is considered as the most important mean of transport of oxygen ...

Social Module: Venice

1) What is the name of your city, town or village and where did this name come from? Note, there may also be an informal name, that is a name that local people refer to it. You may also discuss any name changes over time and the reasons for these name changes. In that case, if the word Veneti has the Indo-European origin, it means “famous”, but if we consider this word with the pre-Indo origin, it means “foreigners” or “new comers” (nuovi venuti). Perhaps the name of the Veneto is from the word “new comers”. In this case, ...

Fuel Cell Technologies in Passenger Cars

Fuel Cell Technology The last decade is characterized by the rapid development of research activity in the field of fuel cells, thus, creating the conditions for their uptake in electric systems. The basic fuel cells’ operating principle has been known for 150 years. However, a variety of technical and financial problems had kept them on the margins of technological applications (Brandon & Hart, 1999). The basic difference between a fuel cell and batteries is that while batteries store energy, fuel cells directly convert a fuel’s chemical energy into electricity by an electrochemical reaction (i.e. Without requiring combustion or movement ...

Abstract

The choice between breastfeeding and bottle (formula) feeding appears to be one of the fundamental decisions that await both new and expectant parents. Quite a number of health bodies including World Health Organization (WHO), American Academy of Pediatrics (AAP), and also the American Medical Association (AMA), all recommend breastfeeding to be the appropriate choice for infants (Andres, Cleves, Bellando, Pivik, Casey, & Badger, 2012). Breastfeeding assists defend against several chronic conditions, prevent allergies, and protect against infections. The AAP, in particular, recommends that infants be breastfed exclusively for the first six (6) months following their birth. Beyond that, breastfeeding is ...

Discussion question

The heart tissues and muscles are designed in such a way that they continuously pump blood into and out of the heart. This implies that the cells within the heart muscles and tissues have to remain active for the nature lifetime in order to support the delicate mechanism of pumping blood. These cells however may reach a point where they cannot support the pumping of blood enough to sustain the required amount of blood in various parts of the body. In these instances, the heart muscles cannot contract strongly and well enough and this reduces the amount of blood ...

BERNOULLI’S EXPERIMENT

INTRODUCTION This experiment aims to verify Bernoulli’s equation that relates the pressure and the velocity of a fluid. The aims of the experiment are: A venturi meter is a device used in fluid measurements. It uses a converging section of a pipe in order to change fluid velocity or pressure. The venturi meter in this experiment is used several times to estimate flow rates and measure piezometric head values at different points along the venturi meter. The fluid used in this experiment is water. Bernoulli’s equation is a mathematical model for ideal fluids. Because of this, the ...

Sinkholes are a problem across the globe, especially in urban areas. Sinkholes can cause damage to roads, collapse structures, and destroy property. The biggest way to prevent a sink hole is to learn what factors are included in the formation a sinkhole is, how a sinkhole forms, and wheatther or not the sinkhole was naturally formed or if humans created the situation that caused the sinkhole in the first place. While it is not possible to actually prevent natural sinkholes, there are several ways that sinkholes which are created from human activity may be prevented, or at least ...

Abstract

Permanent magnet synchronous motors (PMSM) are a type of motors that have permanent magnets mounted on the rotors instead of the rotor windings. This particular design gives the motor a few advantages over ordinary induction synchronous motors. The magnets attached to the rotor do not require excitation, which reduces the power consumption in PMSM. This gives the motor high operational efficiency and reduces the motor active diameter. PMSM are therefore associated with applications that require high torque but have limited operation space. The permanent magnets suffer from flux leakage and are therefore aligned in a pattern that minimizes flux ...

Water scarcity is a global problem that affects several places and regions around the globe. The phenomenon of water scarcity is hitting drier places hard . The impacts of water scarcity in these places have been severe. For example, impacts of water scarcity include crop failure, lack of food and extended starvation amongst populations and death due to waterborne disease in places where water scarcity forces people to consume dirty water. It is on these backgrounds that several individuals, community based organizations, non-governmental organizations, United Nations agencies and government agencies have put together concerted efforts to address the challenge of ...

Abstract

In most parts of the Arab countries, the limited resources of water pose adverse constraints to both the social and economic development, while also threatening the people’s livelihood. The available surface water keeps on declining, and the ground water over-pumping that goes beyond the natural recharge rates has continued to cause great negative impact in the lowering of water table. Over-pumping of ground water also increases ground water salinity, ground water depletion, and ecological degradation (SCENR 5). The outcome prompted the Qatar government to start regulating its water resources as a measure ...

According to EPA (2016), environmental management involves the development of systems aimed at reducing environmental impacts of various activities. In the Brundtland commission report (WCED), sustainable development has been described as development aimed at meeting the current needs of the present generation. However, as the current generation focuses on meeting their own needs, their activities should not compromise the capability of future generations to also meet their own needs. Available evidence suggests that the future generation would have challenges meeting their own needs if the current generation fails to adopt sustainable practices. The sustainable development incorporates the triple line: ...

Pump Application: Building Water Pump

Pumps are devices used to move fluids from one point to another by creating differences in pressure between the two points. Pumps are powered by a prime mover, which can be either a diesel engine or an electric motor. The pump converts the energy supplied by the prime mover to potential energy by pressurizing the fluid it’s pumping. For example, a diesel pump has an engine that converts chemical energy in the fuel to mechanical energy in the form of torque. The torque from the engine is then picked up and transmitted to the pumping mechanism for fluid ...

I have selected the heart failure condition since I have got interest in learning more about it and have a better understanding of how to provide the required care to patients with this condition. Heart failure is a cardiac condition that occurs when muscles responsible for pumping blood out of the heart are not strong enough to perform this function. The main reasons that may cause the heart not perform its function well include; the coronary arteries are not being wide enough thereby making the heart weak in terms of pumping blood efficiently. Alternatively, the heart cannot fill with ...
