I am wondering if the term "gouge coring" when analysing soils typically refers to a specific hand auguring method? Can gouge coring be conducted via a mechanical method, such as rotary core drilling? What type of equipment can one use for gouge coring?

Many thanks.

I would like to insert the interactive map at the following link directly into a PowerPoint presentation and thus remove the need to open the link during the presentation.

I am wondering if this is possible to do, if so how do it do it.

Many thanks,

When I try to turn on my laptop, I am seeing the following error message:

Intel UNDI, PXE-2.1 (build 083)

Copyright (C) 1997-2000 Intel Corporation

This product is covered by one or more of the following patents: US6,570,884, US6,115,776 and US6, 327, 625

My laptop has a solid state drive (SSD) not a hard disk drive (HDD). I've tried changing the BIOS boot priority but this has not worked. In the BIOS, the hard drive is "not detected.

I use windows 10 operating system. I ran the Lenovo Diagnostics USB tool and got a Final Results Code (U1C3ZWU3R-5PPG79) which I don't know what to do with.

Any help with trying to resolve this issue would be much appreciated.

I need to calculate GHG emissions for a construction project with limited data available. I will definitely need to make assumptions but I don't know what emissions factors to use.

The only information I have is on cubic meters of concrete for certain areas of the project.

Are there any default values I can use for calculating GHGs with only cubic meters of concrete data?

-I will need to make assumption on fuel consumption used by construction equipment

-I will need to make assumptions on electricity consumption used by site offices during construction

-I will need to make assumptions about transport details involved during construction.

Are there any standards or guidelines that I can use for estimating emissions with limited data?

Do I need to include scope 3 emissions?

Your assistance would be greatly appreciated.

I've been tasked at calculating the weight of 65,000 L of refrigerated liquid CO2 (UN Number 2187).

I've asked this question twice now and I've been given 2 different answers, which one is correct?

Here is answer one;

CO2 does not exist as a liquid at 1 atmosphere...

770 kg/m^3 (liquid at 56 atm and 20 °C)...

1 liter = 0.001 m^3...

65,000 liters = 65 m^3...

65 m^3 x 770 kg/m^3 = 50,050 kg = 50.05 metric tons

Here is answer 2;

Important information on environment, health and safety Safety Data Sheet

Carbon dioxide, refrigerated liquid.Molecular weight: 44 g/mol

UN number and proper shipping name UN 2187 Carbon dioxide, refrigerated, liquid

Relative density, liquid: 0,82

Melting point: -56,6 °C

Sublimation point: -78,5 °C

Critical temperature: 31 °C

Autoignition temperature: Not applicable.

Flammability range: Not applicable.

Relative density, gas: 1,52

Solubility mg/l water: 2000 mg/l

Density of liquid CO2 = 0.82 x 62.4lf/ft^3 = 51.168lb/ft^3 x 1 ft^3/28.317 liters = 1.807 pounds per liter

65,000 liters x 1.807 #/liter = 117,455 pounds = 53.277 tonnes

Can you assist in determining which answer is correct, perhaps both are incorrect?

I'm not sure if this can be solved but it would be really great if people could help me with this one.

I've been tasked at calculating the weight of 65,000 L of refrigerated liquid CO2 (UN Number 2187).

Normally I would be able to perform this calculation myself or use an online conversion site.

However, upon researching the properties of refrigerated liquid CO2 (UN Number 2187) I noticed that it is actually considered a compressed gas. I have been given the unit in litres (65,000 L) and then find out that refrigerated liquid CO2 is a gas which should be (m3), hence my confusion. I need the answer in Tonnes, hope you can help.

I've already done this calculation and come up with an answer of 72.7 tonnes CO2. I'd like to see if others get the same answer and to see what conversion standards you used, thanks guys.

We have 95 T8 light bulbs in our office, I had been laid to believe that T5 bulbs were the most suitable alternatives however upon some research I've discovered that it is not a sensible option. What is the best solution and the fastest ROI alternative to T8s?

We have 57, 400 Watt metal halide mercury vapor lamps in our industrial ware house ceiling. Is there an energy efficient alternative to this lighting display.

I am in business and we have a carbon footprint report compiled every year by an environmental solutions company. Sure they inform us of our emissions but what is the advantage of knowing all this info. I'm beginning to wonder if its worth the cost of having the reports compiled.

I am conducting a project on International reporting of fuel usage for marine vessels. The aims of the project are to determine a ships statutory obligations to report its;

1. Fuel Consumption

2. Oil Consumption

3. Carbon Emissions

4. Gas Emissions.

I am wondering do vessels have to report these figures to an international organisation or to a state government body? Are the rules different for each country or is there an international agreement?

Any assistance would be greatly appreciated.
