Hiking Essentials for Your Dog's Backpack
In a previous article, I talked about the Approach™ Pack by Ruffwear, which by the way is an excellent pack. Well, okay you have the pack or may have ordered one, so what goes in the pack.
1.) The obvious of course, is food, water and collapsible plastic bowls for the food and water. These will always be in the pack. Know the weight so you can stay at the 25 percent of body weight. Once you have the weight of the essentials, you can start weighing and adding other items up to the weight limit, so what other items should you have.
2.) Climbing rope will always come in handy because you can never have too much cordage, but the weight will be a problem so you have to pay attention to the rope weight. Accidents happen and your dog may injure itself and may need to be lifted out of a crevice or ravine and you will need climbing rope to do this, not to mention you may need it yourself, and, of course, have quality climbing grade carabiners in the pack.
3.) Next, you can add a first aid kit for your pet that addresses any current needs, such as maintenance medications and then items for any emergencies. An Israeli bandage is ideal because the design allows for a pressure fit over a wound in the event of an animal attack, or for an injury caused by a fall and so on.
4.) Noisemaker to warn bears, yes, to warn bears because they really do not want to come out and greet you. Therefore, you can hang a small bell on your dog's pack so a bear can…
a reinforcing agent in polypropylene (PP) nanocomposites. The logistics of the seminar that was most enjoyable was when the speaker focused on the matter of Nanocelluloses. She provided a lot of information on this topic and I understand how it related to her topics in her research. However, the only part that I did not like about the speaker’s presentation was that there was not enough information on polypropylene nanocomposites. Without the background of the polypropylene provided, I could not…
Fun Facts about Polypropylene:
In 2013, the global market for polypropylene was around 55 million metric tons.
Invented in 1954 by Giulio Natta of Milan, Italy
It can be represented by this symbol:
Objects made of polypropylene
Structure of Polypropylene
Chemical Formula: (C3H6)n
Polypropylene is a polymer* with a crystalline structure.
- For the crystalline region, many monomer propylene will bond together…
Physical properties of PHB:
PHB physical properties similar to polypropylene. However, PHB is perfectly isotactic and does not include any chain branching like, for instance, PE. During processing, it flows easily. It is insoluble in water and soluble in chloroform and other chlorinated hydrocarbons. It exhibits good barrier properties against oxygen and compared to other biopolymers. It possesses better physical properties than polypropylene for food packaging applications. (Chaijamrus &…
L., Budinski-Simendić, J., Gvozdenović, J. J., & Simendić, B., 2010) Thus, the manufacturer has a demand for packaging material that are made of polymer that have a well-defined barrier against unwanted moisture, flavors, and gases. A high obstruction packaging can be comprised of numerous layers and many types of mastics. This provides the advanced material goods for things like extending the shelf life of a food product and the ability for the food packaging to allow certain gases that can…
delivery system. Plastic has been an alternative to glass in prefilled syringes since the early 1990’s. Earliest plastics were, however, made of polypropylene which did not offer the clarity of glass, many of its barrier properties or ease of sterilization. Polypropylene plastics also presented more challenges regards to extractables and leachables than glass due to the lack of historic data.…
The objectives of the experiment are:
• Measurement of creep deformation in 2 materials; lead and polypropylene at room temperature.
• Determine how creep deformation of chosen materials can be affected by stress.
• Recognise that the two classes of materials show differences in creep behaviour.
• Awareness of creep as a design consideration.
Structural materials are often placed in service under a certain applied load at elevated temperatures (eg. wind…
The material such as polypropylene (PP). Polycarbonate, polyethylene terephthalate, High density Polyethylene and silicone were selected based on the literature reviews. Considering the easy availability of the material at affordable cost, flexibility of the material for fabrication, polypropylene was chosen to make outer shell of the vaginal cone. Stainless steel, copper, Brass, Carbide materials were selected for making inner weights of the vaginal cone. Out of these materials stainless steel…
material mentioned above has to be taken into an appropriate ratio to compound the batch sample. Generally, to test the property change in the polymer by the influence of a filler/additive is done by processing several batches with different but gradual loading of the filler/additive.
Here, we have to test the properties of nano Calcium Carbonate in the polymer matrix of polypropylene. For this, 12 batches are prepared by using the different size of filler by loading it at 5%, 10%, 15% and 20%…
excellent tear and chemical resistance. Polyurethane is abbreviated as PU, and is available in a wide range of densities, and hardness levels. Some of the common applications of this polymer are bushings, gaskets, seals, and electronic parts.
• Low Density Polyethylene (LDPE): This is one of the widely used and inexpensive thermoplastic with excellent lubricity. This plastic is soft, easy to fabricate, and is not recommended for applications above 150 oF. This polymer is lightweight, and…
