...Free radicals are chemical species that contain a singly occupied orbital. They are neutral and tend to be highly reactive and is a species with an odd number of electrons. When a bond is broken both electrons of that bond remained with one of the atoms but for the formation of radicals, one electron of the bond remains with each of the atoms called hemolytic bond cleavage. Our body generates free radicals reactive oxygen species and reactive nitrogen species by various endogenous systems, exposure to different physiochemical conditions or pathological states. A balance between free radicals and antioxidants is necessary for proper physiological function. Free radicals thus adversely alter lipids, proteins, and DNA and trigger a number of human diseases. Formed in the body during oxidation, a normal by-product of metabolism,...

...116. Free radicals (see Problem 115) are also important in many environmentally significant reactions. For example, photochemical smog, which forms as a result of the action of sunlight on air pollutants, is formed in part by the following two steps. The product of this reaction, ozone, is a pollutant in the lower atmosphere. Ozone is an eye and lung irritant and also accelerates the weathering of rubber products. Write Lewis structures for each of the reactants and products in the preceding reactions. Valence electrons: O has 6 and N has 5 Total valence electrons: 1N(5)+2O(6) = 5+12=17 According to the book Nitrogen does not have an octet. NO = 5+6= 11 and O is 6 O(6)+2O(6)=18 O=N-O: ⟶∶N=O: + :O: :O:+:O≡O:⟶:O=O-O: 132. Aerosol cans carry clear warnings against incineration because of the high pressures that can develop upon heating. Suppose a can contains a residual amount of gas at a pressure of 755 mm Hg and a temperature of 25 °C. What would the pressure be if the can were heated to 1155 °C? P1V1/T1 = P2V2/T2 P1=755mm Hg T1=25 °C T2=1155 °C Volume is constant. P_2=(P_1 V_1 T_2)/(T_1 V_2 ) P_2=((755mm Hg)(1)(1155°C))/((25°C)(1)) P2=34881mmHg 104.

Ts-1 was isolated from the fruiting body of a wild Cordyceps sinensis, one of the best known traditional Chinese medicine and health foods. The antioxidant activities of hot-water extracts from cultured mycelia of Tolypocladium sp. were assessed in different in vitro systems. The extracts showed superoxide dismutase (SOD) activity of 35.6 U/mg protein and are effective in scavenging superoxide radical in a concentration dependent fashion with IC50 value of 1.3 mg/mL. As a reinforcement of the action, similar radical scavenging effects of the extracts were also discerned with both site-specific and non site-specific hydroxyl radical using the deoxyribose assay method. 1,1Diphenyl-2-picrylhydracyl (DPPH) radical scavenging activities of the extracts reached more than 75.2% at the concentrations of 3-6 mg/mL. The extracts showed moderate reducing power and ferrous ion chelating activity. Moreover, the protective effects of the extracts against hydrogen peroxide (H2O2)induced lesion to rat PC12 cell (pheochromocytoma cell line) was observed in a dose-dependent manner from 0.25 to 2.0 mg/mL. Our results suggest that the aqueous extract...

Further, I can see others I know well in the field as fitting the description of the tempered radical, at least in some circumstances and at different times. The reviewers, while suggesting changes, as reviewers do, were also very taken with the paper. It is intellectually interesting, and evocative. It provides us with a perspective on organizational issues that is typically glossed. It opens an arena for organizational analysis that is missed in most theoretical frameworks. Tempered radicals, Meyerson and Scully argue, are individuals who identify with and are committed to their organizations and also to a cause, community or ideology that is fundamentally different from, and possibly at odds with, the dominant culture of their organization. Their radicalism stimulates them to challenge the status quo. Their temperedness reflects the way they have been toughened by challenges, angered by what they see as injustices or ineffectiveness, and inclined to seek moderation in their interactions with members closer to the centre of organizational values and orientations. The paper is a scholarly treatment of a complex concept. It is radical in its charge to us to see new possibilities in the study of organization. It is tempered, even hopeful, in its prescriptions for harnessing participants who are often on the margins of organizational life and who have much...

...survivors to hospital discharge, neurologic impairment often remains a lasting morbidity (Becker et al., 1993). A large body of evidence from animal models indicate that hyperthermia (a temperature higher than the threshold value of 37C) due to brain injury or ischemia can exacerbate the degree of permanent neurological damage following cardiac arrest. Each degree Celsius higher than 37C can cause cerebral destruction through increased metabolic expenditure, excitatory neurotransmitters resulting in calcium cellular reflux and accumulation of oxygen free radicals (Busto et al., 1987). To improve the outcome of patients who survive cardiac arrest requires not only reducing the ischemic process as quickly as possible, caused by cardiac arrest, but also preventing post resuscitation syndrome caused from reperfusion (Safar, 1993). Cerebral reperfusion after successful resuscitation can trigger harmful chemical cascades such as oxygen free radical production which can result in multifocal brain damage. Therapeutic hypothermia (TH) is considered as an effective method for reducing the deleterious neurological outcomes in patients who have out-of-hospital cardiac arrest. Clinical and animal studies have shown that TH following cardiac arrest reduces both the cerebral metabolic rate and oxygen demand and it is thought to attenuate reperfusion injury, global inflammation and endothelial dysfunction, all consequences of cerebral ischemia. Over the...

...6 December 2011 Radical Couch Potato. The concept of being radical conjoins up images of out of control extremists seeking to institute drastic change and forcing it upon everyone. The thought of doing nothing also has radical implications. Dose placing the extremist next to the couch potato present an easy contrast to examine or do they share more in common than we would anticipate? It’s hard to determine which course, action or lack of action, is the scariest. The wearing blinders approach is a contributing factor to many social problems that we all face. Our acceptance of these views makes us equal to the ones presenting them. We witness the viewpoints of radicals every day in the news media. They draw the major attention and focus due to the fact they prey upon the emotions and fears of ordinary people. Groups and individuals expressing extreme beliefs sometimes seek a response that may be violent, and that scares us most of the time. That’s why being bystanders produces no action or outcome, which is considered radical, unlike the activist who displays their agenda openly. The media allows these far reaching actions and ideas to consume our narrow view of our world. By taking little or no action against the militants who seek to control the destiny of the majority we become the militant through our inaction. The political process produces differing opinions, which many are considered deep-rooted in their parties. The extreme right verse...

...government, economy, and society have changed in the areas of federal government activism, agriculture, and industry. Events concerning the government were the radical reconstruction that played a great deal in government activism, the Homestead Act that affected agriculture, and J.P. Morgan which practically save the industry from a complete collapse. The economy’s occurrences and people that helped in maintaining economic levels while also bringing them to a downfall were the interstate commerce, Munn V. Illinois, and the Sherman Antitrust fund. Affairs such as the Radical reconstruction was a form of the federal government activism that worked toward enforcing civil and political equality for the ex-slaves which cause neo-confederates in attempt to make congress desolate the act. Radicals called for another reconstruction which was then called the Military Reconstruction Act, which was to begin political reform and to “suppress insurrection, disorder, and violence. The radical reconstruction worked to gain black suffrage and recognizing native born blacks as citizens rather than a just a lower race of the human species. The Military Reconstruction Act exceeded expectations, the act made efforts to disable neo-confederates, and remove any person in government power willing to disagree. With people fighting against the Radical Reconstruction Act, such as President Andrew Johnson (1865-1869), people continued to make ex-slaves suffer. A freedman said “Give us our land and we take...

...Assess the contribution of feminist sociologists to an understanding of family roles and relationships. In this essay I will explore the different schools of feminism such as Marxist, liberal and radical feminism, who share the view that women are oppressed in a patriarchal society but differ in opinion on who benefits from the inequalities. Each school of feminism has their own understanding of family roles and relationships which I will assess through this essay. Firstly one must look at the division of domestic labour and conjugal roles. Conjugal roles refer to the roles performed by men and women in relation to housework, childcare and paid work. Traditionally men had the instrumental ‘bread-winning’ role which the women had the expressive role (childcare and primary socialisation). Feminists say that the traditional division of labour is neither natural nor beneficial to women as their expressive role is unpaid and taken for granted. However different feminist views disagree on who benefits from this unpaid labour. Marxist feminists would argue it is capitalism that benefits most as wives keep their husbands happy and therefore they are left with a content workforce. On the other hand, radical feminists would argue that men are the main people to gain from women’s oppression as we live in a patriarchal society. A functionalist view from Wilmott and Young says that there has been a ‘march of progress’ in which the family has become more symmetrical with more joint conjugal...

...© Guillaume Herbaut © Guillaume Herbaut Feminism & FEMEN Abstract Through feminism protest, women have been trying to get equal rights to men for decades. Different movements have appeared through the years. Radical feminism is one of them. Where does it come from? What differences does it have from “classical” feminism? For a few years now, we can often see in the media pictures of those bare breasts women protesting, the FEMEN. Where do they come from? What are they fighting for, or against? In this paper, we will have a closer look at where from comes their movement and what defines their ideology in order to understand their message and what they protest against. Methodology For this work, I used what the FEMEN movement wrote, its manifesto and different articles, and tried to find feminist theories on radical feminism in order to understand the basis of the FEMEN movement.

...movies, books, and even cartoons feminist are portrayed as angry, unkempt, lesbian “man haters”. They are shown looking down on men and judging women for their attire or life choices. On rare occasions the media actually shines a positive light on feminism and its beliefs only when it can be beneficial to its rating or purpose. The feminist agenda is not about equal rights for women," said Pat Robertson, a television evangelist and former Baptist minister during his GOP convention speech in 1992. "It is about a socialist, anti-family political movement that encourages women to leave their husbands, kill their children, practice witchcraft, destroy capitalism, and become lesbians." Although most misinterpretations of feminism are not so radical, many have degraded feminists or might have discouraged women from joining the feminist movement. In 2004, the...

...expression that corrupts people's behaviour, therefore defending the suppression of pornography because it perpetuates gender stereotypes, as women are reduced to nothing more than sex objects which promotes violence against women and that men are viewed as “naturally” oppressive and violent and they are ruled by their sexual natures. Opponents also believe that even if pornography is viewed as speech it should be treated as a low value form of speech that is not entitled to First Amendment protection. According to the Radical feminist view, men are socialized to have sexual desires and to feel entitled to have those desires met, whereas women are socialized to meet those desires and to internalize accepted definitions of femininity and sexual objectification. As men cling to the masculine idea that their sexuality is an absolute expression of their need and dominance, they prevent women from effecting new attitudes, self-realizations, and behaviours.

...The Union victory in the Civil war in 1865 gave millions of slaves their freedom. Although they were free former slaves had many new challenges to face during the rebuilding of the South. This time period is known as Reconstruction (1865- 1877). The reason this time is called Reconstruction is because this was the period when the federal government restored the seceded states to the Union. During the era of Reconstruction there were massive changes in American culture, economy, and politics. Before the Civil war was over President Abraham Lincoln began to prepare his plan for Reconstruction. Lincoln’s plan for Reconstruction was one of forgiveness, he did not want to punish the southerners. Lincoln’s plan for Reconstruction was that a southern state could be readmitted to the Union once 10 percent of its voters, who voted in the 1860 election, swore an oath of allegiance to the Union, this plan was called the “10 Percent Plan”. Radical Republicans did not agree with President Lincoln’s plan and they came up with their own plan to counter President Lincoln’s. This plan was the “Wade Davis Bill”, which required 50 percent of a states registered voters to swear an ironclad oath of allegiance to the Unites States. President Lincoln was able to block this bill from passing, but unfortunately he was assassinated before he was able to act on his plan for Reconstruction. President Lincoln’s assassination was a major turning point for this time in history. If President Lincoln had...

...Root Of Violence Against Women " Each year an estimated 2 to 4 million women in the United States are abused by their male partners. Many of them are severely assaulted, and thousands are killed" (thehotline.org). Statistics such as these are phenomenal. Domestic abuse does not only appear as physical harm but there is a lot of damage dealt with psychological abuse which is just as bad. Domestic violence is a widespread issue throughout the world, mostly due to fear created by the abuser. This problem is recognized worldwide and many theorists such as Nussbaum, Mackinnon and Dworkin have shared and organized their thoughts as to why such an uproar of violence has been rising within our society against women. In order to understand why violence against women is at such a high percentage we must first take a look at and understand what are the contributing influences and factors which play an active role in causing the abuser to inflict acts/thoughts/desires of violent intent onto a female. I shall analyze and go into depth of the theories coined by the names mentioned above as to what they think the root of violence is. But first we need to understand that violence against women does not only consist of physical/emotional damage, but also violation of their entitled rights as an individual human being. When we begin to treat a person as anything less or begin to expect more we have committed an act of violation on their human rights. "Objectification entails making into...

...Unit I: Essay Exam: Reconstruction & Rise of Industry US History Since 1877 Professor Valdenia Winn February 14, 2013 According to Dictionary.com, radical means: 1. Of or going to the root or origin; fundamental: a radical difference. 2. Thoroughgoing or extreme, especially as regards change from accepted or traditional forms. Historians identified Congressional Reconstruction as “radical” because of how the South tried to elude the Thirteenth Amendment. Because of these extreme circumstances the federal government had to intervene, which at that point made it radical to most historians. The root of the problem was slavery and the problem solver was the Thirteenth, Fourteenth and Fifteenth Amendments. The Thirteenth Amendment prohibited slavery. The Fourteenth Amendment established national citizenship for persons born or naturalized in the United States. It also prohibited the states from depriving citizens of their civil rights or equal protection under the law as well as reduced state representation in the House of Representatives by the percentage of adult male citizens denied the vote. The Fifteenth Amendment forbade states to deny citizens the right to vote on the grounds of race, color, or “previous condition of servitude”. Another problem solver was the establishment of the Freedmen’s Bureau, which was there to aid former slaves get on their feet and supervise “all relief and educational activities relating to refugees and...
