Forensic Entomology - Insects solving crimes

Fresh Fly

1.What is the main food source for the insect?
Ans.Fruit fly larvae are possible prey of ants staphylinid beetles. Chickens and other fowl may eat fruit fly larvae present on overripe fruits and vegetables and sometimes consume fly pupae found beneath trees. Other common larval and pupal fruit fly predators include predaceous wasps wasps, mites and crickets 

2. How does it help determine the time of death at a crime scene?
Ans. When a suspicious death occurs, a forensic entomologist may be called to assist in processing the crime scene. Insects found on or near the body may reveal important clues about the crime, including the victim's time to death.

3.What is the time length and description of it's life cycle?
Ans. Fruit files undergo three stages of development before emerging as adults: egg, larva and pupa. At room temperature, fruit flies can develop into adults within one to two weeks. The egg and larval stages span approximately eight days, while the pupal stage lasts six days. The adult fruit flies lives for several errks. 

4. Describe what the insect looks like and post a picture of it.
Ans. It's look like exactly honey bee but thios fruit fly could cause a human very easily with dangerous poison.

House Fly

1. .What is the main food source for the insect?

Ans. The main food source of houseflies are milk, sugar, blood, feces, and decaying organic matter such as fruits and vegetables. Houseflies also require a source of water. Larvae also eat paper and textile materials such as wool, cotton and sacing if it is kept moist and at suitable temperatures.

2. How does it help determine the time of death at a crime scene?

Ans. Entomology is the study of insects, and forensic entomologists use insects to provide information about crimes.

3.What is the time length and description of it's life cycle?

Ans. With a day housefly eggs hatch into larvae,also known as maggots. Maggotos are legless white insects that feed from the egg laying site for three to five days

4.Describe what the insect looks like and post a picture of it.
Ans. This looks like a bee. This insect could kill other insects very easily

Fingerprint Assignment

FBI 30 Year Old Murder Solved

The case was officially re opened and assigned to the cold case squad doug herout. working with the laboratory technicians and analysts. FBI solved a big criminal case and it got so popular. They found a guy with using his fingerprints. In 1978 61 year old Carroll Bonnet was stabbed to death in his apartment. Police got successful by using his fingerprints. Everyone got shocked when they find the killer after for like 30 years approximately. He was in his house one day and literally the police came up to his house and caught him. When he murdered officers found that he was trying to clean up the blood but badly he left his fingerprints there. When he came out from that building he went to drive the car but he had blood on his left hand and when he opened the door that door had his fingerprints. The police found his car after so many days and sent it to the lab for testing. Lab testers found fingerprints, blood, a pistol from the back and black jacket. In that jacket there was a knife too.

Hybrid and Electric Cars Web Resources

 Electric cars work

Electric cars are something that show up in the news all the time. There are several reasons for the continuing interest in these vehicles. Electric cars create less pollution than powered cars, so they are an environmentally friendly alternative to gasoline-powered vehicles (especially in cities).

The environmental impacts of electric vehicles.

The electric power system is changing and, especially, the electrical distribution system will meet  new features. One of the large changes is a transformation of the transportation sector with the use of electricity, with introduction of electrical vehicles and Plug-in Electric Vehicles (PEVs). This will pose new challenges and opportunities for the electric distribution companies. This paper analyzes the effects of PEVs charging on the local 400 V and 10 kV electric distribution systems in the city of Gothenburg, Sweden, using steady-state power flow analysis. Two different areas representing residential area and commercial area have been simulated for the worst-case scenario, which is simultaneous charging of all the vehicles during the peak load period.

The advantages and disadvantages of using electric vehicles

Electric traction is one of the most promising technologies that can lead to significant improvements in vehicle performance, energy utilization efficiency, and polluting emissions. Among several technologies, hybrid electric vehicle (HEV) traction is the most promising technology that has the advantages of high performance, high fuel efficiency, low emissions, and long operating range. Moreover, the technologies of all the component hardware are technically and markedly available. 

The major challenges facing implementation of electric vehicle

The battery management system (BMS) is a critical component of electric and hybrid electric vehicles. The purpose of the BMS is to guarantee safe and reliable battery operation.

Paper airplane lab

Our planes were faster than everyone else 

Parachute experiment

Height-5.3m

Time-20s

Velocity-0.265

Questions and Answers 

1. What adjustments/changes did you make to your design after trying it first time?

Ans. At first when we tried it was only in air for like 5.3 seconds but then we put some tape to make it heavier. At the second time it was in the air for like 20 seconds. It worked really well. 

2. What forces acts the parachute?

1. Ans. Once the parachute  is opened, the air resistance overwhelms the downward force of gravity. The net force and the acceleration on the falling skydiver is upward. An upward net force on a downward falling object would cause that object to slow down. The skydiver thus slows down.
   
   
   3. What changes would you make to transport something heavier?
   Ans. Put equal weight on the wings. 
   

   
   

Transparent Airplane coming out in 2050

Transparent Airplane is a great technology which is coming out in 2050. Engineers decided that In 2050 they will call Airbus instead of Airplane. Future aircraft could be using a bionic structure that mimics the bone structure of birds. Bone is both light and strong because its porous interior carries tension only where necessary.

Ocean Acidification

1. What is ocean acidification?
Ans. The process of ocean acidification is surprisingly simple. Carbon dioxide from the burning of fossil fuels accumulates in the atmosphere, where it cause global warming. But it also affects our oceans. Ocean acidification refers to a reduction in pH os the ocean over an extended period time, caused primary by uptake of carbon dioxide (CO2) from the atmosphere.

2. What human activities have caused this problem?
Ans. Human impact on the environment includes on biophysical environmenta and other resources. The term anthropogenic designates an effect or ovject resulting from the human activity.

3. How much has the acidity of the ocean changed?
Ans. As long as there is carbon dioxide in the air the ocean will continue to become more acidic.

4. How does the increased acidity affect animals in the ocean?
Ans. A lot of the fishes and sea creatures are going to extinced, because of the carbon dioxide.

5. How are pink salmon affected?
Ans. The climate change and prove that the oceans are more acidic than ever now. The 15% water imperative increase.

6. How are coal reefs affected?
Ans. Human activities thay reater the coal reeks in many ways corel from US the human variable seasons serve stroms

7. How might ocean acidification affect you?
Ans. Ocean acidification affects US in many reasons some of the things that we drink comes from the ocean.

8. What can you do to decrease CO2 eemissions?
Ans. We can decrease CO2 not that alone because there are 7.8 billion people on this planet and everyone contributes to the pollution of the populations.

Acid Base Neutralization Lab [Part - 2]

In part two {Buffere}

pH paper turned into pink and yellow with the different chemicals. 

Acid Base Neutralization Lab [Part - 1]

First part 

We created neutralization reaction with different concentrations of Hydrochloric acid [HCL] and sodium hydroxide [NaOH] and tested the pH paper. We came up with 5 different colours.

Part second 

In the second part we put cabbage juice into those test tubes to change their colour to purple. 

Third part 

As you can see in the first picture every test tube was in a different coulour. But with the cabbage juice those test tubes turned to kind of purple colour. 

HCL 1.0m was the stronger acid. 

NaOH 1.0m was the stronger bace. 

Acids and bases

I did acids and bases in the lab today. I did everything properly as you can see in that picture. As you can see the chemical A, B, C and D tubes changed into different colours because of the cabbage juice. I had my goggles on. After I done my chemical lab I put everything back on spots.
