Carbon monoxide Content of Exhaust Emissions from Agricultural Tractor Engine...IJAEMSJORNAL
This study aims at contributing to the information buildup required for advocating the need for urgent reduction of environmental pollution by exhaust emissions from fossil fuel powered Engines in Nigeria. It was, concluded from the results obtained from the study that carbon monoxide content of the exhaust emissions of agricultural tractors are approximately forty nine(49) times higher than the recommended maximum level of 0.5 % vol CO (v/v) by the US Environmental Protection Agency (EPA). FIAT 70-666 contributed the largest content of 2.9 % vol of CO (v/v) while MASSEY FERGUSSON MF 375 contributed the least amount of 1.7 % vol of CO(v/v). Only the engine capacity had significant effect on the carbon monoxide content of the exhaust emissions of the agricultural tractors; the model/make selection did not significantly affect the CO content of their exhaust emissions.
Effect of Adding Oxygen Containing Additives to Unleaded Gasoline on Exhaust ...ijiert bestjournal
As world population grew,power plants,factories a nd ever increasing automobiles began to pollute the air to the extent that it was no longer acceptable. During the late 1940s,air pollution as a problem was fir st recognized in the Los Angeles basin in California . Two causes of this were the large population densit y and the natural weather conditions of area. Smoke and other pollutants from many industries and automobiles combined with the fog that was common in this ocean area and smog resulted. By the 1960s emission standards were beginning to be enforced in Californ ia. Then various ways are investigated to reduce em issions from an IC engine. Oxygen containing additives are used to improve gasoline�s performance and reduce exhaust emissions is one of them. The main objectiv e of this work is to find can Dimethyl Carbonate is used to reduce emission? In view of the above,it is decide d to investigate the effect of adding Dimethyl Carb onate to unleaded gasoline on exhaust emission. The experime ntal setup to test blended fuel is prepared with mu lti cylinder four stroke spark ignition engine. The res ults indicate that CO and HC exhaust emissions are lower with the use of Dimethyl carbonate gasoline blended fuels as compared to the use of unleaded gasoline. The effect of above additive on NOx is insignificant.

In Environment there are Different things are effected, in all things "Air Pollution " is to dangerous to Human Wealth. This study of the Present thie Effect of the Air Pollution to human and Natural Resources and Environment.
Outdoor air pollution kills more than 3.5 million people across the world every year, and causes health problems, from asthma to heart disease, for many more. This is costing OECD societies plus China and India an estimated USD 3.5 trillion a year in terms of the value of lives lost and ill health, and the trend is rising. But how much of the cost of those deaths and health problems is due to pollution from cars, trucks and motorcycles on our roads? Initial evidence suggests that in OECD countries, road transport is likely responsible for about half the USD 1.7 trillion total.
Based on extensive new epidemiological evidence since the 2010 Global Burden of Disease study, and OECD estimates of the Value of Statistical Life, The Cost of Air Pollution provides evidence that the health impacts of air pollution are about four times greater than previously estimated and the economic costs much higher than previously thought.
These Highlights outline the key messages in the report.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS
