			Whereas [[magnetostriction]] characterizes the shape change of a ferromagnetic material during magnetization, the inverse magnetostrictive effect characterizes the change of domain magnetization when a stress is applied to a material. This magnetostriction can be positive (magnetization increased by tension) like in pure [[iron]], or negative (magnetization decreased by tension) like in [[nickel]]. In the case of a single stress <math>\sigma</math> applied on a single magnetic domain, the magnetic strain energy density <math>E_\sigma</math> can be expressed as:<ref>{{cite book
			\| last = Bozorth \| first = R.
			\| title = Ferromagnetism \| publisher = Van Nostrand \| year = 1951
			}}</ref>

			<math>E_\sigma = \frac{3}{2} \lambda_s \sigma \sin^2(\theta)</math>

			where <math>\lambda_s</math> is the magnetostrictive expansion at saturation, and <math>\theta</math> the angle between the saturation magnetization and the stressed direction.
			When <math>\lambda_s</math> and <math>\sigma</math> are both positive (like in iron under tension), the energy is minimum for <math>\theta</math> = 0, i.e. when tension is aligned with the saturation magnetization. Consequently, the magnetization is increased by tension.

			In fact, magnetostriction is more complex and depends on the direction of the crystal axes. In [[iron]], the [100] axes are the directions of easy magnetization, while there is little magnetization along the [111] directions (unless the magnetization becomes close to the saturation magnetization, leading to the change of the domain orientation from [111] to [100]). This [[magnetic anisotropy]] pushed authors to define two independent longitudinal magnetostrictions <math>\lambda_{100}</math> and <math>\lambda_{111}</math>.

			* In [[Cubic crystal system\|cubic]] materials, the magnetostriction along any axis can be defined by a known linear combination of these two constants. For instance, the elongation along [110] is a linear combination of <math>\lambda_{100}</math> and <math>\lambda_{111}</math>.
			* Under assumptions of [[isotropic]] magnetostriction (i.e. [[Magnetic domain\|domain]] magnetization is the same in any crystallographic directions), then <math>\lambda_{100} = \lambda_{111} = \lambda</math> and the linear dependence between the elastic energy and the stress is conserved, <math>E_\sigma = \frac{3}{2} \lambda \sigma (\alpha_1 \gamma_1 +\alpha_2 \gamma_2 + \alpha_3 \gamma_3)^2</math>. Here, <math> \alpha_1 </math>, <math> \alpha_2 </math> and <math> \alpha_3 </math> are the direction cosines of the domain magnetization, and <math> \gamma_1 </math>, <math> \gamma_2 </math>,<math> \gamma_3 </math> those of the bond directions, towards the crystallographic directions.

Not surprisingly, unemployment, disability, depression and anxiety are greatly reduced following bariatric surgery.

With gastric sleeve and [http://tinyurl.com/kecvhhb discount ugg boots] gastric bypass surgery, [http://tinyurl.com/kecvhhb discount ugg boots] diabetes remission or improvement often happens early after surgery - long before there is significant weight reduction. Mobility and Freedom All those extra pounds definitely weigh you down. You don't have the freedom of movement you'd like to have. There are so many things you would enjoy doing but can't because the excess weight makes everything so difficult. One of the requirements of weight loss surgery is the commitment to lifestyle changes which include being more physically active. The more physical you get, the more weight you will lose. As you lose more weight, it will be easier and easier to get out there and do the things you've always wanted to do. Look for activities that are not just good exercise, but fun too. The more fun you have, the less it feels like work and the more it feels like something you want to do! Self love and self esteem Everyone knows what a wonderful person you are except you! You berate and belittle your self based on just one characteristic - your weight. After bariatric surgery, you'll feel good about how you look. Maybe there's an annual party you usually dread because all your clothes make you look fat. Won't it be fun to see everyone and for them to see you in your new clothes that make you look so thin! Sexual desire and fulfillment Let's face it - it's hard to feel sexy when you're overweight. Married people tend to hide their bodies from their partners out of shame and embarrassment. Single people won't put themselves out there because, "who would want me anyway?" Overweight men may experience sexual problems that include erectile dysfunction and shortness of breath during intercourse. Dramatic weight loss achieved with weight loss surgery promotes an increase in testosterone levels, which may yield a better sex life.

They are less likely to avoid sexual situations and more willing to be seen getting undressed. They enjoy sex more and have sex more often. Savings You may not realize just how much those extra pounds are really costing you and not just emotionally, but financially too. The average person struggling with obesity pays: $611/month for medicine associated with obesity $224/month for health care expenses $260/month for non-surgical weight loss programs such as (Jenny Craig, etc.) $150/month in lost wages from missing work $501/month in grocery bills Within the first year of bariatric surgery patients can expect to see the following savings: 60% Reduction in medicine related to obesity 15% Reduction in [http://tinyurl.com/kecvhhb cheap ugg boots] healthcare expenses 100% Reduction in non-surgical weight loss program expenses 28% Reduction in lost wages 60% Reduction in food expenses With so many great reasons [http://tinyurl.com/kecvhhb cheap ugg boots] to have weight loss surgery, what's stopping you?
