Holly has been working at a large construction company for three years. Although an intern, Holly has earned the respect of her peers. Her supervisor (and project manager), along with her coworkers, constantly support her by teaching her new materials and encouraging her to tackle new tasks. For one specific project, her supervisor chose her to visit the job site for the construction of flood retaining walls. Holly is familiar with the protocol required by her company, and her boss trusts her to always wear protective equipment every time she goes into the field. However, when she went to the job site for this project, she heard someone yell, “Be careful not to break a nail!” while she was walking down a particularly steep mud slope. She dismissed the comment at first, but throughout the remainder of the project, different construction workers would make condescending remarks and gestures at her. They would call her ‘Princess’ or hold out their arms as though expecting her to fall, slip, or hurt herself. Holly feels she is being treated disrespectfully because of her gender, but never brings it up to her supervisor as the workers were subcontracted from various companies by the General Contractor. Holly doesn’t feel right getting other people in trouble for such little comments and is worried long term about how her success might be affected if she makes a complaint. Should Holly say something?

What are the current concerns regarding natural gas delivery systems in the United States? What can be done to improve them?Natural gas delivery systems do have issues and concerns. Natural gas in itself mainly consists of methane which is considered a greenhouse gas. This is bad for the environment overall. The storage, transportation, etc contribute to 4 percent of total US methane emissions. Drilling a natural gas well on land may require clearing and leveling an area around the well site. Well drilling activities produce air pollution and may disturb people, wildlife, and water resources. Laying pipelines that transport natural gas from wells usually requires clearing land to bury the pipe. Natural gas production can also produce large volumes of contaminated water. This water requires proper handling, storage, and treatment so that it does not pollute land and other waters. Natural gas wells and pipelines often have engines to run equipment and compressors, which produce air pollutants and noise.Natural gas is often referred to as a ‘bridge’ fuel? What is meant by this, and is this moniker valid?Natural gasadvocates characterize it as abridge fuel.Theimplication is that we will use it now, to achieve short-term greenhousegasreductions by replacing coal-fired power, then reduce or end reliance onnatural gasover some time period to lock in long-term greenhousegasreductions. While at first glance this makes sense but overtime due to leakage the new coal fired plants. There are some periods in the next 30 years when gas will result in more climate impact than new coal plants. If leakage is higher than 4 percent, there are some periods when gas will be worse for the climate than existing coal plants.What are the benefits or consequences involved with liquefying natural gas in order to export gas acquired from the Marcellus and Utica shales?EnvironmentalBenefits ofLNG.Natural gasisthecleanest burning fossilfuel and theincreased useof natural gascan significantly improve local air qualityandpublic heath as well as reduce carbon dioxide (CO2) emissions.The push for exports makes sense for producers who have become the victims of their own success. U.S. Natural gas prices have plummeted in recent years due to increased production in gas plays like theMarcellus Shale. The price of natural gas in the U.S. now hovers around $3.50 per million British thermal units. But in Europe that same amount of gas fetches more than $10. So exports would help producers by reducing domestic supply and increasing prices. The report, conducted for the DOE by the economic consulting firmNERA, says exports make sense as long as there’s a glut of natural gas with low production costs in the U.S. and a high demand overseas. The study concludes that new LNG export terminals would result in just slight increases in the price of natural gas. The consequences of liquefyingnatural gas is air pollution. Cleaner burning than other fossil fuels, the combustion ofnatural gasproduces negligible amounts of sulfur, mercury, and particulates. Burningnatural gasdoes produce nitrogen oxides (NOx), which are precursors to smog, but at lower levels than gasoline and diesel used for motor vehicles.What impact does the discovery of the Marcellus and Utica shales have on US energy policy overall?Federally these discoveries have little impact on the US energy policy. This is mostly up to each state to decide on what they want to do. Currently, Pennsylvania, Ohio, and West Virginia are at the heart of the eastern shale gas leasing and drilling boom, with tens of thousands of wells drilled and permits for thousands more already issued. In December 2014,New York announced it would prohibit high volume hydraulic fracturing in the statedue to growing evidence of damage to the environment and human health. The process has also been on hold inMarylanddue to public opposition and an in-depth review of risks and impacts; however, in November 2014 the state completed that work and issued regulations,signaling the possibility that drilling could move forward. In the meantime, gas production has expanded in Pennsylvania and Ohio—giving rise to plans for a network of new pipelines and compressor stations region-wide to get the gas to market, as well as increasing volumes of waste that must be managed and disposed of.Resourceseia (2020).

please state that my address is 1100 north frio city gate apartments apartment 507 san antonio texas 78207 . i robin pennington is writting you this letter because i have not been able to work for 11 months due to a slip and fall at work on august 21st 2019 and broke my left wrist.i am still on workmans comp and need my stimulus check to help me get back on my feet to pay rent,bills,medication,food And transportation.please help me.thank, sincerely, Robin pennington.

1. Reduce the levels outlined in the table below using the collimation method, apply only the appropriate checks. Point I is a benchmark with a level of 56.174m above datum. Adjust the calculated levels so that the results at I agree with the specified level.If the distance from A to H is 220m calculate the mean gradient between the two points. Outline the practical precautions that must be taken for accurate leveling.

Explain briefly: 1- The effect of metals point on their modulus of elasticity. 2- The effect of heating temperatures on the modulus of elasticity of materials. Give the reason for the following statements : 1- Grey cast iron used in construction of heavy duty machines 2-White cast iron very hard and brittle 3- The mechanical properties of ductile iron and malleable iron approximately the same 4- Ductile iron with pearlite matrix stronger than ductile iron with ferrite matrix. 5- Compact graphite irons (CGIs) is used for manufacturing exhaust manifolds.
