Smoking pathophysiological effects

Pathophysiological Effects There are several pathophysiological effects that are associated with smoking and a majority of smokers are at risk of suffering from one of these effects or the other. Mobascher and Wintere (2008) point out that the pathophysiological effects of smoking are usually brought about by the many harmful chemicals that are contained in tobacco.Advertising We will write a custom research paper sample on Smoking: pathophysiological effects specifically for you for only $16.05 $11/page Learn More According to Mobascher and Wintere (2008) these chemicals have been shown to have adverse effects in the smoker’s body and even those people who are exposed to second hand smoke. The chemicals normally adversely affect most of the body’s principal organs including the heart, lungs, kidneys and brain. Starting with the heart, smoking has been shown to result to damage of the arterial walls. This consequently compromises the arteri es capacity to transfer blood to the heart effectively. This implies that the arteries capacity to supply oxygen to the heart might be compromised with resulting to heart related medical complications such as heart attacks or strokes. In addition to the heart, smoking also might result to adverse effects on the lungs and indeed the entire respiratory system. Mobascher and Wintere (2008) assert that smoking can result in reduction of the lung capacity consequently leading to breathing difficulties. Some of the specific ways through which smoking can result in reduced lung capacity include; reducing the size of airways and increasing the rate of accumulation of mucus material in the lungs. These effects have the impact of increasing the lungs vulnerability to infectious diseases including lung cancer (Mobascher Wintere, 2008). Dependence on Nicotine In addition to the effects of smoking on the various body organs including the heart and lungs, smoking has also been shown to have adve rse effects on the brain resulting to a compromise of the entire nervous system. According to Porth (2010), nicotine, one of the chemicals contained in tobacco, is responsible for the brief â€Å"feel good† feeling that is usually brought about by smoking. This feeling, as pointed out by Porth (2010), is usually directly as a result of stimulation of a specific part of the brain known as the mesolimbic system. It is this stimulation that results to the fell- good effect of nicotine.Advertising Looking for research paper on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More However, Porth (2010) notes that the stimulation and the resultant effect brought about by nicotine is short lived, and this aspect is what is behind the addictive effects of tobacco. This is because, in order to experience this effect the smoker needs to ‘light up’ many times. In doing so, their chances of suffering from one or more of th e aforementioned health effects of smoking, is increased. Moreover, Porth (2010) asserts that as one continues to engage in smoking, their tolerance levels to nicotine and other chemicals contained in tobacco keeps on increasing. Overtime, a person who used to smoke two cigarettes to experience the stimulating effects of nicotine might be required to smoke about five cigarettes, for the same dose of stimulation. Despite the obvious health risks associated with smoking, there are proponents of this risky habit and this group of people has advanced various reasons for their stand. Porth (2010) points out that one of the arguments that is being touted as a benefit of smoking by the proponents of this risky habit touches on the suppressing effects of cigarettes. According to Porth (2010), smoking has been shown to be effective in suppressing the effects of various mental disorders. Thus, many people argue that it can be effective in treating mental illnesses. In addition to that, the su ppression effects of smoking has also been applied in the treatment of various addictions such as alcohol and cocaine addictions whereby the addicts are allowed to use cigarettes to suppress some of the ‘cravings’ that they might have during the rehabilitation exercise. However, this suppression effect, just like any other smoking effect, is temporary. Consequently, many addicts who depend on smoking to help them fight their addictions usually end up relapsing.

Understanding Owner vs. Parent in Delphi Applications

Understanding Owner vs. Parent in Delphi Applications Every time you place a panel on a form and a button on that panel you make an invisible connection. The Form becomes the owner of the Button, and the Panel is set to be its parent. Every Delphi component has an Owner property. The Owner takes care of freeing the owned components when it is being freed. Similar, but different, the Parent property indicates the component that contains the child component. Parent Parent refers to the component that another component is contained in, such as TForm, TGroupBox or a TPanel. If one control (parent) contains others, the contained controls are child controls of the parent. Parent determines how the component is displayed. For example, the Left and Top properties are all relative to the Parent. The Parent property can be assigned and changed during run-time. Not all components have the Parent. Many forms do not have a Parent. For example, forms that appear directly on the Windows desktop have Parent set to nil. A components HasParent method returns a boolean value indicating whether or not the component has been assigned a parent. We use the Parent property to get or set the parent of a control. For example, place two panels (Panel1, Panel2) on a form and place one button (Button1) on the first panel (Panel1). This sets Buttons Parent property to Panel1. Button1.Parent : Panel2; If you place the above code in the OnClick event for the second Panel, when you click Panel2 the button jumps from Panel1 to Panel2: Panel1 is no longer the Parent for the Button. When you want to create a TButton at run-time, it is important that we remember to assign a parent - the control that contains the button. For a component to be visible, it must have a parent to display itself within. ParentThis and ParentThat If you select a button at design time and look at the Object Inspector youll notice several Parent-aware properties. The ParentFont, for example, indicates whether the Font used for the Buttons caption is the same as the one used for the Buttons parent (in the previous example: Panel1). If ParentFont is True for all Buttons on a Panel, changing the panel’s Font property to Bold causes all Buttons caption on the Panel to use that (bold) font. Controls Property All components that share the same Parent are available as part of the Controls property of that Parent. For example, Controls may be used to iterate over all the children of the windowed control. The next piece of code can be used to hide all the contained components on Panel1: for ii : 0 to Panel1.ControlCount - 1 do   Ã‚  Panel1.Controls[ii].Visible : false; Tricking Tricks Windowed controls have three basic characteristics: they can receive the input focus, they use system resources, and they can be parents to other controls. For example, the Button component is a windowed control and cannot be the parent to some other component - you cant place another component on it. The thing is that Delphi hides this feature from us. An example is the hidden possibility for a TStatusBar to have some components like TProgressBar on it. Ownership First, note that a Form is the overall Owner of any components that reside on it (positioned on the form at design-time). This means that when a form is destroyed, all the components on the form are also destroyed. For example, if we have an application with more that one form when we call the Free or Release method for a form object, we do not have to worry about explicitly freeing all of the objects on that form- because the form is the owner of all its components. Every component we create, at design or run time, must be owned by another component. The owner of a component- the value of its Owner property- is determined by a parameter passed to the Create constructor when the component is created. The only other way to re-assign the Owner is using the InsertComponent/RemoveComponent methods during run-time. By default, a form owns all components on it and is in turn owned by the Application. When we use the keyword Self as the parameter for the Create method- the object we are creating is owned by the class that the method is contained in- which is usually a Delphi form. If on the other hand, we make another component (not the form) the owner of the component, then we are making that component responsible for disposing of the object when it is destroyed. As like any other Delphi component, custom made TFindFile component can be created, used and destroyed at run time. To create, use and free a TFindFile component at run, you can use the next code snippet: uses FindFile;...var FFile : TFindFile;procedure TForm1.InitializeData;begin //form (Self) is the Owner of the component   //there is no Parent since this   //is an unvisible component.   FFile : TFindFile.Create(Self) ;   ... end; Note: Since the FFile is created with an owner (Form1), we dont need to do anything to free the component- it will be freed when the owner is destroyed. Components Property All components that share the same Owner are available as part of the Components property of that Owner. The following procedure is used to clear all the Edit components that are on the form: procedure ClearEdits(AForm: TForm) ;var   Ã‚  ii : Integer; begin   Ã‚  for ii : 0 to AForm.ComponentCount-1 do   Ã‚  if (AForm.Components[ii] is TEdit) then TEdit(AForm.Components[ii]).Text : ;end; Orphans Some controls (such as ActiveX controls) are contained in non-VCL windows rather than in a parent control. For these controls, the value of Parent is nil and the ParentWindow property specifies the non-VCL parent window. Setting ParentWindow moves the control so that it is contained in the specified window. ParentWindow is set automatically when a control is created using the CreateParented method. The truth is that in most cases you do not need to care about Parents and Owners, but when it comes to OOP and component development or when you want to take Delphi one step forward the statements in this article will help you to take that step faster.

Mary the Jewess, First Known Alchemist

Mary the Jewess, First Known Alchemist Mary the Jewess (around 0-200 CE) was the first known alchemist in history. She lived in Eygpt and invented processes and apparatuses that were used for centuries after that. Her story became something of a legend in later Arabic and Christian writings. Life and History Occupation: Alchemist, inventor Also known as: Maria Hebraea, Maria Prophetissima, Maria Prophetissa, Maria the Hebrew, Miriam the Prophetess; Mariya the Sage; Mary the Prophetess (16th and 17th centuries) Early source: 4th-century alchemist Zosimos of Panopolis, who called her the sister of Moses Mary the Jewess and her alchemical contributions are documented by Zosimos of Panopolis in his text Peri kaminon kai organon (On Furnaces and Apparatuses), which may be itself based on a text by Mary. He also quotes her extensively in The Coloring of Precious Stones. According to Zosimus and later renderings of Marias writings, alchemy was like sexual reproduction, with different metals being male and female. She described the oxidation of metals and saw in that process the possibility of transforming base metals into gold. The saying credited to Mary the Jewess, Join the male and the female, and you will find what is sought, was used by Carl Jung. Later Writings About Mary the Jewess Variations on the story of Mary are told in sources after Zosimus. The church father Epiphanius, bishop of Salamis, mentions two writings by Mary the Jewess, Great Questions and Small Questions, where he credits her with a vision of Jesus. Marys story is also retold in Arabic writings where she is supposedly both a contemporary of Jesus (having carried the infant Jesus) and Ostanes, a Persian brother-in-law of Xerxes, who lived about 500 BCE. Legacy The name of Mary the Jewess survives in two terms used in chemistry. The water-bath, a term used for both a process and a device, is also called in Romance languages the bain-marie or baà ±o maria. The term is still used in cooking today. The bain-marie uses heat from water in a surrounding vessel to keep a consistent temperature, something like a double boiler. Marys black is also named for Mary the Jewess.  Marys black is a black sulfide coating on metal which is produced using the process of kerotakis. Mary the Jewess also invented and described the alchemical apparatus and process called the kerotakis and another apparatus called the tribokos. Bibliography Raphael Patai.

Library Science - Essay Example Personal records should represent individuals as social agents and produce a proper representation of a character. Most archives have always focused on the collective aspects of individuals while neglecting the personal reflection. Personal archives demand an appraisal approach that differs from organization archives. Archivists should implement several considerations when conceptualizing records. Recording of personal archives involves documenting singular views of people and revealing their individual expression as opposed to group opinions. Archivists implement intimacy when designing personal records. Reflection of the intimacy comes from the organization and content of the records. The appraisal theory of personal archives emphasizes on individual character of creators (Hobbs, 2001). Shifting to personal archives will enable the institutions to provide a good representation of organizations by expressing individual-based views. It is imperative to capture the personality of individuals in archives. Hobbs, 2001, attempts to change views of archival appraisal by encouraging the professionals to value personal opinions in archives rather than inclination on collective expressions. The article describes the criteria that archivists should use in identifying collections. The setting of the project is based in Yale University Library. The article describes a project whose aim is Hyry, Kaplan and Weideman, 2002, propose a rational approach for collection of faculty papers in the university. The article uses Minnesota method to find its effectiveness in the case study. It proposes the need to develop proper approaches of collecting faculty papers by institutions of higher learning. It explains a project that the Yale University Library undertook in Manuscripts and Archives (Hyry, Kaplan & Weideman, 2002). The project involved application of the methodology from Minnesota Historical Society. The article illustrates an

Fundamentals of Decision Support Essay Example | Topics and Well Written Essays - 1000 words

Fundamentals of Decision Support - Essay Example Decisions are required when managers handle a situation with two or more alternative courses of action. To select the right course of action, the manager must analyze all the relevant information available. Information with no monetary figure requires a qualitative decision. Quantitative decisions, like in this scenario, are accompanied by measurable information mostly in financial figures. A quantitative decision problem is made up of six components. Decision problems involving two or more variables are a common occurrence when managing a business. A high number of variables increase the level of complexity of the decision to be made. All variables have to be considered when making such decisions. There are methods used to analyze a decision problem. Common decision problem analysis methods include the simplex method and cost- volume- profit technique. Computer programs have also been developed to aid in the decision-making. The computer decision support software includes DecisionPro and Microsoft Excel (Brandimarte, 2012).  £12 per unit. Product 2 has a profit margin of  £16 per unit. The setup cost for manufacturing facilities required to produce the two products also vary. Product 1 production facility installation cost is  £45000 while for product 2 the setup cost for its production facility is  £76000. The company has two factories capable of producing the two products. The rate of production of the two factories varies. Factory 1 can produce 52 units of product 1 per hour and 38 units of product 2 per hour. Factory 2 can produce 42 units of product 1 per hour and 23 units of product 2 per hour. Factory 1 has 480 hours available for production of the two products. Factory 2 has 720 hours available for production of the two products. The aim of this solution is to optimize the profits the company will derive from producing the two products with the limited resources the company has. The constraints, in

The Monastery Essay Example for Free

The Monastery Essay I am a currently trained in Military Free-Fall, so it would be safe to say that I have knowledge by observation and participation. I have enjoyed watching skydiving competitions on television and in the military. As a kid I can remember wanting to do that when I grew up. When I joined the Special Forces in 1989 I knew my chances were greatly increasing for me to participate in skydiving operations, but it wasnt until 1995 when that final moment would arrive. I enjoy the excitement of participation in a skydiving operation that consists in small numbers of personnel to a mass group. There are several stages a beginner will go though until their first jump without an instructor. First let me tell you about the training that I went though in my quest to fulfill my childhood dreams. Since I had been trained in basic airborne operations (static line jumps) this made an easier to transition into skydiving operations for the instructors. The initial training begins with what we call tabletop drills. An instructor places everyone on a tabletop and talks you though the basic movements techniques that you will perform in the air. This is where you learn basic turns, flips, formations, rolls and other various drills. The next step you learn is how to pack and inspect your parachute in less than five minutes. The vertical wind tunnel is the second phase of training you go though in order to practice you tabletop drills before you actually perform a real jump. Once you have demonstrated your skill to an instructor that you can perform the entire basic task only then will you be allowed to move onto the last phase of training. The last phase of training is jumping out of an aircraft up to 12,500 feet above sea level. Your first jump an instructor hangs on to you while you exit the aircraft to ensure you stabilize yourself in the air. One you have done this he lets go and instructs you to perform the basic task you learned earlier, while grading you on your performance. Wow what a rush of adrenalin you get on your first jump at that height. Now its up to you to complete the rest of the training that you learned earlier during the course. Time management is a very hard concept for me to get a grasp on. This is one subject that everyone has knowledge of by both participation and observation. I have attended lecture from top-level executives on this subject down to basic level training by correspondence with limited success. My daily experiences with time management are quite different from that of a person who has a routine job. With my job changes are made at the last minute. For example, I could be in the process of gathering research for a project to deploying the next day (unannounced) to a remote country to train foreign troops in unconventional warfare all due to shortage of personnel on operational teams. Our job (Special Forced Intelligence Sergeants) has been referred to as the jack-of-all-trades, master of nothing. This stems from out extensive knowledge of all military type operations and training, but not given the time to focus on one specific skill. At times this can be very frustrating job with the constant change that effect a daily scheduled, but rewarding in other aspects due to the various activities that you may encounter along the way. The President of the United States is a subject that I have only knowledge by observation. I have learned a great deal just by watching the man and the office. I learned a small portion about politics in school because it was not a particular interest to me at the time. Now it has a great impact on my job and my future it has become more interesting to me. I listen to each candidate when they run for office to determine which one is the best suited for the job. I have learned a lot about the candidates just by watching them interact with the media during their debates. In the past the Presidency has been a very respectable and well sought out title to hold as a politician. In todays society the Presidency has lost some prestige due to men that held that position and allowed their selves to fall to corruptions and scandals.

The One Child Policy and Gender Inequality Essay -- chinese culture,e

Given the high sex ratio in recent China population report, the abnormally excessive male birth exemplifies the persistence of son preference on women’s fertility behavior. Son preference rooted in Chinese agriculture-based economy and historical feudalism, in consistence with the reliance on laborers and continuing the family line. Older people prefer to depend on their sons to get financial and physical support, while daughters are regarded as property of their husband’s family since the day of marriage. However, the wish of having multiple children, especially boys, was challenged by the strict One Child policy in 1979. The One Child policy, also known as Family Planning policy, was implemented across the country as one of fundamental national policies under the administration of Population and Family Planning Commission. Based on the purpose of lowering fertility rates to ease social pressure and improve living standard, a married couple is only allowed to have one child with some exceptions made for some ethnic minorities and rural families. The majority of citizens are classified by ethnics and occupations to fit the specific regulations of compensations and punishments to prevent them from having a second child (Li, J., & Cooney, R, S. 1993). This proposal eventually triggered a profound introspection which chronically melted patriarchal cultures. The broad topic of how government’s decisions altered social norms is discussed within five sociological studies in my essay in allusion to the impacts of One Child policy on gender inequality.
