Introduction Chocolate is a sweet delicacy that has gained much popularity among various persons across the world.In particular, chocolate consumption is mainly common among children and ladies with men preferring it mainly during important occasions such as wedding celebrations and anniversaries celebrations (Januszewska & Viaene, 2002). Many people, ladies and children like consuming chocolate owing to its sweet composition. Earlier on, chocolate consumption was shunned due to its high-fat content. Many people associated chocolate consumptions with acne, caries, obesity, coronary artery diseases, high blood pressure as well as other critical illnesses such as diabetes (Macdonald, 2004). As a result, its consumption faced the major set back in its making history. Many physicians, as well as nutritionists, warned their patients against consuming large amounts of chocolate. Recent discoveries on biologically active phenol compounds such as cocoa that are currently used in making chocolate has widely changed the perception of the society about the same. In relation to this recent breakthrough extensive and intensive research has been stimulated into looking at the effects of chocolate consumption on ageing, oxidative stress, blood pressure regulation, and in controlling atherosclerosis (Matsui, Ito, Nishimura al, 2005). This research investigates the association between chocolate consumption and the occurrence of acne among college girls from Oklahoma State University.
Research objective and hypotheses
This research seeks to establish the contributions of chocolate in the occurrence of acne among college girls from Oklahoma State University. The research also seeks to validate the hypothesis that chocolate consumption is the major cause of acne among college girls from Oklahoma State University. The null hypothesis guiding this research is that chocolate consumption is not linked to the occurrence of Acne among college girls from Oklahoma State University.
Research methodology
50 female students were used in this experiment. The population was picked at random and divided into five groups (again at random). Four groups will be subjected to consuming milked chocolate at the rates of 10g, 20g, 30g, and 40g respectively. The fifth group will the control group and will be subjected to 0g of chocolate consumed per day. The experiment will be done mainly during the afternoon hours when most of the students are through with their classes and are relatively willing to consume the food. The relationship between chocolate consumption and the occurrence of acne will be determined by observing the level of sebum in the sample population. According to Macdonald, (2004), clear skins have an average sebum reading of about 200 mg/cm2 while acne skin has an average sebum reading of about 300 mg/cm2. Data analysis and interpretation was conducted using ANOVA and correlation analysis to establish the associations between the dependent and the independent variable in the experiment.
Results and discussion
ANOVA analysis on chocolate amounts consumed by each group and sebum levels recorded indicated a strong significant relation between chocolate consumption and the occurrence of acne with a p- value of 0.002. Regression analysis on the four sets at 95% confidence level and alpha- to- enter and alpha- to remove at 0.15 presented p- values of 0.002, 0.000, 0.000, and 0.000 for groups 1- 4 respectively. Based on the regression results above, it was concluded that there is a strong significant effect of chocolate consumption on the development of acne in ladies thus validating the alternative hypothesis. The mean sebum levels for the groups in each set were recorded as 256.45, 267.56, 274.83, and 285.37 mg/cm2 for groups 1, 2, 3 and 4 respectively. The readings on the control experiment indicated sebum reading of 203 mg/cm2 indicating that they have a clear skin. The null hypothesis was disapproved based on the correlation analysis conducted at a confidence level of 95%. It was, therefore, concluded that consumption of chocolate leads to the occurrence of acne in female students from Oklahoma State University.
Conclusion
In conclusion, it is good to reiterate in this part that chocolate consumption and the development of acne especially among women has raised a lot of concern. Researches have been carried out to try and establish the validity of this argument without specific answers given. This research has plainly established that chocolate consumption has a significant relationship with the occurrence of acne among ladies.

...?Introduction Remote sensing techniques can be used reliably to ify vegetation and to differentiate between vegetation of different kinds. This paper will attempt to analyse the relationship between image characteristics and vegetation cover as well as bio mass. Different techniques such as RVI and NDVI will be utilised. The various sensors used will be Landsat TM, Lansat MSS and NOAA AVHRR. The Landsat TM is used for thematic imaging only and can reveal only a limited amount of information such as the availability or non avialblity of vegetation. On the other hand the Landsat MSS (multi spectral surveillance) can be used to distinguish between various kinds of vegetation too. The NOAA AVHRR sensor is used to estimate the thermal... Remote...

...has to continuously find his way back to the original piece of writing because of the distractions available on the internet. The world of internet has transformed into a “universal medium,” (Carr, Is Google making us stupid?) even when one is not working; he/she is likely to be browsing, looking at emails, reading news articles or watching movies or listening to music. I can easily relate to this problem identified by Carr as being a student we have to make projects and have to work on internet but it is so difficult to focus and I usually end up facebooking rather than completing the project that I am supposed to. “Once I was a scuba diver in the sea of words. Now I zip along the surface like a guy on a jet ski” (Carr)...

.... Laws imposed to promote the recycling of used resources for a sustainable future (Ackerman, 1997). Lately, the government has also provided incentives for families and citizens to recycle. These incentives raised the participation of participants from 7% to 90% (Carless, 1992). There has been strong evidence that recycling brings about negative effects to our ecosystem. Lets us discuss further as to the validity of this claim. Using the means of observation by researchers, recycling has also started taking its toll onto the ecosystem. Further in this paper, I will discuss various viewpoints made based on observations. We will see how recycling, a common practice nowadays, is slowly taking its toll onto our...

On another perspective, the writer might decide to combine their ideas with the ones already documented to come up with a basically new concept. In very...

Responds to Reading and Writing about Research

...Reading and Writing about Research Working with scientific articles requires skills and experience. For the first as for most young and unprepared people, academic language is one of the most obvious obstacles preventing from effective information analysis. The authors of scientific researches got used to the speech saturated with specific terms, definitions, and complicated methods of information presentation. Practice is probably the only way to adjust to this obstacle as reading more and more scientific articles people learn to capture the gist leaving secondary information behind. The terms when once interpreted do not cause...
