Resistance may refer to:
Physics
- Electrical resistance The electrical resistance of an object is a measure of its attraction to the passage of a steady electric current. An object of uniform cross section will have a resistance proportional to its length and inversely proportional to its cross-sectional area, and proportional to the resistivity of the material, a measure of the degree to which an object opposes an electric current through it
- Friction Friction is the force resisting the relative lateral motion of solid surfaces, fluid layers, or material elements in contact. Its colloquial opposite is slipperiness. Friction is usually subdivided into several varieties:, the force that opposes (relative) motion
- Drag (physics) In fluid dynamics, drag refers to forces that oppose the relative motion of an object through a fluid (a liquid or gas). Drag forces act in a direction opposite to the oncoming flow velocity. Unlike other resistive forces such as dry friction, which is nearly independent of velocity, drag forces depend on velocity ("air resistance"), fluid or gas forces opposing motion and flow
- Geological resistance, a measure of how well minerals resist erosive factors
- Hydraulic conductivity Hydraulic conductivity, symbolically represented as K, is a property of vascular plants, soil or rock, that describes the ease with which water can move through pore spaces or fractures. It depends on the intrinsic permeability of the material and on the degree of saturation. Saturated hydraulic conductivity, Ksat, describes water movement through, the ease with which water can move through pore spaces or fractures in soil or rock
- Thermal resistance In physics, thermal conductivity, k, is the property of a material that indicates its ability to conduct heat. It appears primarily in Fourier's Law for heat conduction. Thermal conductivity is measured in watt per kelvin per metre . Multiplied by a temperature difference (in Kelvin, K) and an area (in square metres, m2), and divided by a, a measure of difficulty of heat transfer through a substance
- Thermal conductivity In physics, thermal conductivity, k, is the property of a material that indicates its ability to conduct heat. It appears primarily in Fourier's Law for heat conduction. Thermal conductivity is measured in watts per kelvin per metre . Multiplied by a temperature difference (in kelvins, K) and an area (in square metres, m2), and divided by a, how well heat is conducted through a substance
- Thermal resistance in electronics Thermal resistance is the temperature difference across a structure when a unit of heat energy flows through it in unit time. It is the reciprocal of thermal conductance. The SI units of thermal resistance are kelvins per watt, or the equivalent degrees Celsius per watt, heat considerations in electronics design
- In materials science, the term is sometimes used for hardness Hardness is the measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied. Macroscopic hardness is generally characterized by strong intermolecular bonds, however the behavior of solid materials under force is complex, therefore there are different measurements of hardness: scratch hardness,
Biology
- Drug resistance Drug resistance is the reduction in effectiveness of a drug such as an antimicrobial or an antineoplastic in curing a disease or condition. When the drug is not intended to kill or inhibit a pathogen, then the term is equivalent to dosage failure or drug tolerance. More commonly, the term is used in the context of resistance acquired by pathogens
- Antibiotic resistance Antibiotic resistance is a specific type of drug resistance when a microorganism has the ability of withstanding the effects of antibiotics. Antibiotic resistance evolves via natural selection acting upon random mutation, but it can also be engineered by applying an evolutionary stress on a population. Once such a gene is generated, bacteria can, the ability of a microorganism to withstand the effects of antibiotics
- Resistance to antiviral drugs Drug resistance is the reduction in effectiveness of a drug in curing a disease or improving a patient's symptoms. When the drug is not intended to kill or inhibit a pathogen, then the term is equivalent to dosage failure or drug tolerance. More commonly, the term is used in the context of diseases caused by pathogens, the ability of a population of viruses to withstand the effects of an antiviral drug.
- Immune system An immune system is a system of biological structures and processes within an organism that protects against disease by identifying and killing pathogens and tumor cells. It detects a wide variety of agents, from viruses to parasitic worms, and needs to distinguish them from the organism's own healthy cells and tissues in order to function, the system in organisms that provides disease resistance
- Plant disease resistance Plant Disease Resistance is crucial to the reliable production of food, and it provides significant reductions in agricultural use of fuel, water, land and other inputs. There are numerous examples of devastating plant disease impacts as well as recurrent severe plant disease issues (see Rice blast, Soybean cyst nematode, Citrus canker). However,
- Disease resistance in fruit and vegetables There are a number of lines of defence against pests and diseases in the organic garden, principle among these being the practice of good husbandry, creating healthy soil and ensuring high standards of garden hygiene. But no matter how diverse and healthy the garden eco-system may be, there will always be a degree of disease and pest presence. In
- Pesticide resistance Pesticide resistance is the adaptation of pest species targeted by a pesticide resulting in decreased susceptibility to that chemical. In other words, pests develop a resistance to a chemical through selection; after they are exposed to a pesticide for a prolonged period it no longer kills them as effectively. The most resistant organisms are the, resistance of insects, weeds, rodents, and other "pests" to improperly used pesticides
- Systemic acquired resistance In plants, systemic acquired resistance is a "whole-plant" resistance response that occurs following an earlier localized exposure to a pathogen. SAR is analogous to the innate immune system found in animals, and there is evidence that SAR in plants and innate immunity in animals may be evolutionarily conserved. SAR is important for, a response in plants that occurs following exposure to a pathogen
- Vascular resistance Vascular resistance is a term used to define the resistance to flow that must be overcome to push blood through the circulatory system. The resistance offered by the peripheral circulation is known as the systemic vascular resistance , while the resistance offered by the vasculature of the lungs is known as the pulmonary vascular resistance (PVR), the resistance to flow that must be overcome in order for blood to circulate through the body.
- Frost resistance, the resistance to low temperatures in plants
Investing

Honestly if VET.UN could settle into a trading range between $36.00 and $33.00 there would be nothing whatsoever wrong with that.
What are good strenth / resistance training exercises I can do at home to help me run better?
Q. I have recently started running again. I would like to do strength/resistance training to help me become a better runner. What type of exercise can I do at home without buying expensive equipment?

A. There's the obvious stuff like push-ups and crunches. Planks [prop yourself on your elbows/arms and toes. lift one leg at a time, 10 times. Then switch to your side, prop your self on one arm/elbow and one side of a foot. lift the other leg 10 times. flip to the other side. And lastly facing the ceiling have your elbows/arms prop you up and be on your heals, then one at a time raise your leg 10 times]. I'm not sure exactly what you were looking for, but hope this helps!
