SBVLC: Secure Barcode-based Visible Light Communication for Smart phonesKamal Spring
As an alternative to NFC technology, 2D barcodes have been increasingly used for security-sensitive applications including payments and personal identification. However, the security of barcode-based communication in mobile applications has not been systematically studied. In this paper, we propose SBVLC - a secure system for barcode-based visible light communication (VLC) between smart phones. We formally analyze the security of SBVLC based on geometric models and propose physical security enhancement mechanisms for barcode communication by manipulating screen view angles and leveraging user-induced motions. We then develop two secure data exchange schemes. These schemes are useful in many security-sensitive mobile applications including private information sharing, secure device pairing, and mobile payment. SBVLC is evaluated through extensive experiments on both Android and I OS smart phones.
In our application we have implemented the idea of QR code as password verification to overcome all the hacking issues. We have two modules as banker and the user. In the user module there will be two categories they are shopping and paying bill. In the shopping section user will shop the product and enter the card and bank details and send request to the banker regarding the transaction purpose. And in turn the banker module there are two categories they are the create OTP and the send OTP details. The banker will check the details of the user request regarding the purchase and all the card and balance details and prepare a password in the form of QR code. The password will be I the form of QR code and will be sent to the user through the mail service to the user personal mail id. In turn the user will pay the bill by loading the QR from the mail and scanning. On scanning the password will generate if the password matches with the banker details the transaction will become successful. Thus password hacking, key logging and eavesdropping issues will be overcome.
This document provides a material safety data sheet for nitrous oxide. Some key points:
1) Nitrous oxide is a colorless, nonflammable gas that can also be liquefied under pressure as a colorless cryogenic liquid. High concentrations can act as an anesthetic or displace oxygen and cause asphyxiation.
2) Inhalation of nitrous oxide can cause dizziness, drowsiness, and nausea at lower concentrations and oxygen deficiency at higher concentrations. Prolonged exposure may damage the nervous system or bone marrow.
3) Contact with the liquefied gas can cause frostbite. The gas may also act as an oxidizer in a fire
Hydrogen Sulfide (H2S)
Hydrogen sulfide is a colorless, flammable, extremely hazardous gas with a “rotten
egg” smell. Some common names for the gas include sewer gas, stink damp,
swamp gas and manure gas. It occurs naturally in crude petroleum, natural gas,
and hot springs. In addition, hydrogen sulfide is produced by bacterial breakdown
of organic materials and human and animal wastes (e.g., sewage).
Industrial activities that can produce the gas include petroleum/natural gas
drilling and refining, wastewater treatment, coke ovens, tanneries, and kraft
paper mills. Hydrogen sulfide can also exist as a liquid compressed gas.
The document discusses the hazards of hydrogen sulfide (H2S) gas exposure, including:
- H2S is extremely toxic and can cause death by inhalation at high concentrations within minutes.
- Even low concentrations can cause symptoms like headaches, dizziness and nausea.
- Detection is difficult as H2S paralyzes the sense of smell, so monitors must be used in its presence.
- Proper protective equipment, emergency procedures, detection methods and safety precautions are outlined to prevent exposure and injury from H2S.
Chronic obstructive pulmonary disease (COPD) refers to a group of lung diseases that block airflow and make breathing difficult. The main cause is tobacco smoking, though indoor air pollution is also a common cause. Symptoms include shortness of breath, wheezing, coughing, and excess mucus. Treatment focuses on medication, lung therapy like oxygen, and smoking cessation. Diagnosis involves pulmonary function tests, chest X-rays, and CT scans to evaluate lung function and rule out other conditions.

CHEMICAL RESEARCH PAPER
1.0 Abstract
Hydrogen sulfide gas has gained a lot of industrial usage in the current times. This has left many people especially those working in such firms to be exposed to the dangers that come with this gas that is largely poisonous hence the need to ensure that the people working in such environments are provided with the personal protective equipment to shield them from the harmful effects of the gas given that their organizational roles keeps them in contact with this gas. This chemical research paper narrows down to the properties of this particular gas, its health hazards for those exposed to it, the common usage of this gas and its regulation by the government within the working environment. This report is very central given that numerous death have resulted from workers being exposed to the toxic effects of this gas hence the need to highlight the core features of this gas and make recommendations that if adopted with the relevant organizations will save lives.
2.0 Introduction
Hydrogen sulfide (H2S) is a gas that naturally occurs in hot springs, crude petroleum, and even natural gas. This gas is usually produced by the breakdown of organic materials commonly found in wastes of human and animals by bacteria. Some of the activities that commonly result to the production of hydrogen sulfide gas include treatment of wastewater, drilling and even refining of petroleum or natural gas (Occupational Safety and Health Administration, 2016).
Aside from being in a form of gas, hydrogen sulfide may also exist as a gas, which is compressed to become a liquid. It is commonly found in places which are enclosed and have poor ventilation because it travels along the ground as a result of its heavier weight than air. Some of the common locations of hydrogen sulfide include basements, and sewer lines (Occupational Safety and Health Administration, 2016).
H2S is becoming public concern, especially because enormous number of industries useH2S in their manufacture. Hence, enormous numbers of workers are exposed to it. In this report I am going to thoroughly explain H2S properties, common use of H2S, health effects, and the government regulation of H2S in .
This document discusses air pollution and smoking. It defines air pollution as the introduction of chemicals, particulate matter, or biological materials into the atmosphere that can harm humans or the environment.

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease characterized by obstructed airflow from the lungs. It is typically caused by long-term exposure to irritating gases or particulate matter from cigarette smoke. The two most common conditions that contribute to COPD are emphysema and chronic bronchitis. Emphysema destroys lung tissue and chronic bronchitis causes inflammation of the bronchial tubes. While COPD is progressive, treatment options can help control symptoms and slow disease progression. Treatment may include quitting smoking, medications like bronchodilators and antibiotics, oxygen therapy, pulmonary rehabilitation, and possibly surgery in severe cases.
This document provides information on oxygen therapy and administration. It outlines 7 learning objectives, including explaining the role of oxygen, identifying those who need supplemental oxygen, describing the respiratory system, and explaining safe oxygen storage and use. It also details 4 groups of patients who may require oxygen therapy, normal breathing rates, signs of low blood oxygen, and appropriate oxygen delivery methods based on patient condition and oxygen saturation levels. Safety precautions for oxygen equipment are emphasized.
Chronic obstructive pulmonary disease (COPD) refers to a group of lung diseases including emphysema and chronic bronchitis that cause airflow blockage and breathing problems. COPD is usually caused by smoking and long-term exposure to other lung irritants. It progressively worsens over time and is characterized by symptoms like shortness of breath, cough, wheezing, and mucus production. While incurable, COPD can be managed through lifestyle changes, medications, oxygen therapy, pulmonary rehabilitation, and sometimes surgery to improve quality of life. Proper treatment aims to control symptoms and prevent exacerbations that can further damage the lungs.
Chronic obstructive pulmonary disease (COPD) refers to chronic conditions like chronic bronchitis and emphysema that obstruct airflow from the lungs. Cigarette smoking is the leading cause of COPD. The document defines COPD and describes its symptoms, risk factors, diagnosis, treatment through medications and surgery, complications, and approaches to managing the disease.

This gas is usually produced by the breakdown of organic materials commonly found in wastes of human and animals by bacteria. Some of the activities that commonly result to the production of hydrogen sulfide gas include treatment of wastewater, drilling and even refining of petroleum or natural gas (Occupational Safety and Health Administration).
Aside from being in a form of gas, hydrogen sulfide may also exist as a gas, which is compressed to become a liquid. It is commonly found in places which are enclosed and hav ...
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease characterized by obstructed airflow from the lungs. It is typically caused by long-term exposure to irritating gases or particulate matter from cigarette smoke. The two most common conditions that contribute to COPD are emphysema and chronic bronchitis. Emphysema destroys lung tissue and chronic bronchitis causes inflammation of the bronchial tubes. While COPD is progressive, treatment options can help control symptoms and slow disease progression. Treatment may include quitting smoking, medications like bronchodilators and antibiotics, oxygen therapy, pulmonary rehabilitation, and possibly surgery in severe cases.
This document provides information on oxygen therapy and administration. It outlines 7 learning objectives, including explaining the role of oxygen, identifying those who need supplemental oxygen, describing the respiratory system, and explaining safe oxygen storage and use. It also details 4 groups of patients who may require oxygen therapy, normal breathing rates, signs of low blood oxygen, and appropriate oxygen delivery methods based on patient condition and oxygen saturation levels. Safety precautions for oxygen equipment are emphasized.
Chronic obstructive pulmonary disease (COPD) refers to a group of lung diseases including emphysema and chronic bronchitis that cause airflow blockage and breathing problems. COPD is usually caused by smoking and long-term exposure to other lung irritants. It progressively worsens over time and is characterized by symptoms like shortness of breath, cough, wheezing, and mucus production. While incurable, COPD can be managed through lifestyle changes, medications, oxygen therapy, pulmonary rehabilitation, and sometimes surgery to improve quality of life. Proper treatment aims to control symptoms and prevent exacerbations that can further damage the lungs.
Chronic obstructive pulmonary disease (COPD) refers to chronic conditions like chronic bronchitis and emphysema that obstruct airflow from the lungs. Cigarette smoking is the leading cause of COPD. The document defines COPD and describes its symptoms, risk factors, diagnosis, treatment through medications and surgery, complications, and approaches to managing the disease.

COPD is a type of obstructive lung disease and related conditions. it is very helpful presentation to you about information of COPD.
It includes all things that is definition, causes, symptoms, pathophysiology, diagnostic evaluation, types, treatment and role of nurses for COPD patient.
Chronic obstructive pulmonary disease (COPD) refers to chronic conditions such as chronic bronchitis and emphysema that obstruct airflow from the lungs. The main causes are cigarette smoking and exposure to air pollutants. Symptoms include shortness of breath, cough, and excess mucus production. Treatment focuses on reducing symptoms through medications like bronchodilators and steroids. For severe cases, surgery or lung transplantation may be options. Managing COPD involves smoking cessation and lifestyle changes to improve lung health.
This document provides information about chronic obstructive pulmonary disease (COPD). It defines COPD as a lung disease characterized by persistent airflow limitation that is usually progressive. COPD often involves a combination of chronic bronchitis and emphysema. Symptoms include a chronic cough, shortness of breath, wheezing and chest tightness. Smoking is the primary cause of COPD. Treatment involves bronchodilators, corticosteroids, vaccines, oxygen therapy, pulmonary rehabilitation and sometimes surgery. The goal of treatment is to reduce symptoms and prevent exacerbations.
COPD - Chronic obstructive pulmonary disease - Aby Aby Thankachan
Obstructive lung diseases are characterized by airway obstruction. Chronic obstructive pulmonary disease (COPD) refers specifically to chronic bronchitis and emphysema, where the airways become narrowed over time due to inflammation and mucus, limiting airflow. The main symptoms of COPD are cough, sputum production, and shortness of breath. A diagnosis of COPD requires respiratory testing showing airflow limitation. While there is no cure, symptoms can be treated through smoking cessation, bronchodilators, pulmonary rehabilitation, oxygen supplementation, and managing exacerbations.
Hydrogen sulfide (H2S) is a colorless, flammable gas with a rotten egg smell that occurs naturally in petroleum and natural gas deposits. It is also produced by bacterial breakdown of organic matter and human/animal wastes. Industrial activities like oil drilling, sewage treatment, and paper mills can release H2S. It is heavier than air, flammable, and toxic even at low levels with prolonged exposure. Inhalation is the primary exposure risk, as it can cause respiratory irritation and is potentially fatal at high concentrations. Proper ventilation and respiratory protection are required when working with or rescuing people from H2S environments.

Industrial activities like oil refining, wastewater treatment, and paper mills can release H2S. The gas is heavier than air, flammable, and toxic even at low concentrations through inhalation of fumes. High concentrations can cause shock or death from a single breath. Proper ventilation and respiratory protection are required when working with or rescuing people from H2S environments.
COPD, or chronic obstructive pulmonary disease, refers to a group of lung diseases that make it difficult to breathe. It is usually caused by long-term exposure to irritating gases and particulate matter, most often from cigarette smoking. The two main conditions that make up COPD are chronic bronchitis and emphysema. COPD is a progressive lung disease that cannot be cured, but early treatment can help manage symptoms and slow its progression. Smoking cessation is critical for COPD patients to prevent further lung damage.

COPD is a set of lung diseases that limit airflow and include chronic bronchitis and emphysema. It is usually progressive and caused by long-term exposure to noxious particles, most commonly from cigarette smoking. Symptoms include shortness of breath, chronic cough, and excess mucus production. Treatment focuses on reducing symptoms and preventing progression through smoking cessation and avoiding further irritants.

2) "The human body is adapted to 21 percent oxygen,
and the blood exiting the lungs already has about 97
percent of the oxygen that it could carry bound to
hemoglobin. Having a higher oxygen fraction in the
lungs serves no purpose, and may actually be
detrimental. The medical profession warns that
individuals with respiratory diseases such as asthma
and emphysema should not inhale too much oxygen.
Higher than normal oxygen partial pressure can also
indirectly cause carbon dioxide narcosis in patients
with chronic obstructive pulmonary disease (COPD). The FDA warns that some flavoring methods
use oils, which if used improperly, and droplets are inhaled, might contribute to an inflammation of
the lungs. Some oxygen bar companies offer safe water-based aromas for flavoring in order to
2. maintain compliance and stay within FDA guidelines.
Also, concentrated oxygen is a flame accelerant which should be kept away from cigarettes and
other sources of ignition. Oxygen may also cause serious side effects at excessive doses. Although
the effects of oxygen toxicity at atmospheric pressure can cause lung damage, the low fraction of
oxygen (30-40%) and relatively brief exposures make pulmonary toxicity unlikely. Nevertheless, due
caution should be exercised when consuming oxygen. In the UK, the Health and Safety Executive
publishes guidance on equipment (including tubing) and on staff training, as well as warning on
potential hazards, and makes several recommendations to ensure safe practice, principally to
minimise fire risks.
Another concern is the improper maintenance of oxygen equipment. Some oxygen concentrators use
clay filters which cause micro-organisms to grow creating an additional danger that can cause lung
infections."
