For hair that needs extra strength, now there is haircare that’s so gentle, yet so strong. The new EverStrong Sulfate-Free Fortify System™ contains L’Oréal’s patented Bio-Ceramide complex, which strengthens hair after just one wash. EverStrong Hydrate Shampoo gently cleanses and nourishes dry hair to leave it strong and silky. Rich lather and natural aromatic properties from rosemary and juniper help energize and invigorate the senses. How-to’sHair Treatments for PerfectionProtective treatments to strengthen and shineEveryday perils like wind, sun, and styling tools can harm delicate tresses. Discover which treatments can help restore its health and strength, leaving you with beautiful hair in any situation.Brave the WildCold temperatures and wind can break hair, which in turn leads to frizz, static, and dullness. Heavy sun exposure dries out hair, weakening its overall strength and elasticity. Also, free radicals and pollution can damage hair cells. Hair treatments fight these environmental threats by hydrating hair and locking in moisture while bolstering hair strength. Vive Pro treatments are specifically formulated with polymers and advanced complexes that revitalize and protect hair and enhance its flexibility and vibrancy.Triumph Over Styling DamageHeated styling tools zap moisture, while overly enthusiastic brushing can wear away hair’s protective cuticles. Dyes, perms, and relaxers can also damage hair. To combat these harmful effects, choose treatments designed to smooth, strengthen, and moisturize hair, leaving it more manageable and beautiful. Treatments with styling polymers nourish hair while detangling, infusing shine, and adding body.Support Your EffortWith all the shampooing, conditioning, and styling, why would anyone possibly need to do more? Because you’re already doing the work necessary for beautiful, healthy hair, adding weekly treatments to your routine will enhance all your efforts. Advanced complexes and other nourishing technologies take your hair to its optimum level of health for the most supple, lustrous, and beautiful locks that could never be achieved by just sticking to the basics.See for YourselfDiscover how Vive Pro treatments can nourish, protect, and illuminate your locks, leaving you at your most radiant.Vive Pro Color Vive Conditioning TreatmentVive Pro Style & Body Infusing Conditioning TreatmentVive Pro Smooth Intense Conditioning TreatmentVive Pro Nutri Gloss Conditioning TreatmentSulfate-Free Hair CareThe beauty benefits of EverPure & EverStrongEver wonder why your new color fades so soon or why your hair loses its luster barely a day after a wash? Look no further than the label of your favorite shampoo. Sulfates, common detergents in hair care products, can strip color and essential oils leaving hair looking dull and prone to breakage. Here are some important facts every beauty addict should know.Care for Your ColorWant to preserve that just-stepped-out-of-the-salon vibrant color? A sulfate-free hair care regimen is de rigueur. Sulfate-based products do more than cleanse your locks—they wash your shade down the drain. EverPure contains Anti-Fade System and UV filters that shield your color. This complete line of shampoos, conditioners and treatment products leaves hair soft, silky and ever-brilliant.Maintain HydrationEven if you don’t color your hair wind, humidity, pollution and styling products can weaken your locks and cause dryness and breakage. Sulfate-based shampoos and conditioners will only worsen the damage. EverStrong hair care is free of harsh chemicals. It contains an advanced Bio-Ceramide Complex which nourishes hair back to health while strengthening it after just one wash.Lose Sulfates, Not SudsAll sulfate-free products are not created equal. Many shampoos that forego sulfates tend to be lacking in the lather department. Thanks to advanced technology, EverPure’s and EverStrong’s gentle formulas produce rich, luxurious foam infused with a refreshing botanical scent. Your hair—and your senses—will thank you!ArticlesTop 10 Hair Care TipsGet picture-perfect hairTip 1After shampoo and conditioning, be sure to rinse your hair thoroughly. Left-over product dulls hair.Tip 2Distributing conditioner through your hair with a wide-toothed comb will leave your hair shiny and tangle-free.Tip 3Apply conditioner from mid-lengths to ends. Conditioning your roots will weigh your hair down.Tip 4If your hair is really dry, deep-condition at home. Apply conditioner to clean, damp hair; slip on a plastic cap and let your hair absorb for 30 minutes.Tip 5Rubbing your hair with a towel when it’s wet can ruffle the cuticle and cause tangles, so gently squeeze out excess water.Tip 6Before blow drying, protect your hair with a styling product such as a conditioning milk, cream, or serum.Tip 7Move your blow dryer from roots to ends to avoid frizz and shredding your hair cuticles.Tip 8For smooth results, brush as you blow dry in the same direction. It will prevent your cuticle from roughing up.Tip 9Make sure your hair is thoroughly dry before styling with a flat iron or curling iron to avoid frizz.Tip 10For a fuller look, part or style your hair in the opposite direction.Be a Natural BeautyGet-gorgeous lifestyle tipsThe key to looking your best is taking care of yourself. Here are a few tips for getting naturally gorgeous--from the inside out.Take H2O to GoWater is essential. If you feel thirsty, you’re already dehydrated. On average, women are advised to drink about 2.5 liters a day, but depending on your level of activity or climate, you may need more. To increase your water intake, keep a bottle with you. You’ll reach for it more often and quickly reap the benefits. From promoting healthy skin to ridding your body of toxins and impurities, water helps keep you looking good and feeling great.Slather on the SunscreenSkin needs protection from the sun’s rays. The UV index has reached scorching levels—and not just in the summer months—so be sure to wear sunscreen every day. For your face, opt for a lotion or foundation that features SPF 15 to help keep skin protected and wrinkle-free. Remember that SPF allows you to stay in the sun longer without burning, but too much sun exposure can still cause damage—even if you’re using SPF 50. So when in doubt, cover up.Eat Your GreensRaw fruits and vegetables are rich in vitamins and antioxidants, which benefit your body inside and out. If you’re feeling sleepy in the afternoon, reach for a green apple. It delivers a better boost than a cup of coffee, plus it provides a feeling of fullness without the heavy meal. To reduce bloating, try cucumbers. Just as they remove puffiness from around your eyes, they can nix bloating by filtering out excess water and sodium from your body. To improve your immune system, reach for tomatoes and pomegranates. They’re rich in antioxidants, and help to flush out toxins while keeping your immune system strong.Catch Some ZzzzsThere’s a reason your mother called it beauty rest. Not getting enough sleep creates stress for the body, which shows up on your face. The recommended amount of sleep for adults is eight hours. You can increase the possibility of getting a good night’s rest by going to sleep at the same time every night. This creates a rhythm for your body to follow. With proper rest, you’ll not only maintain a healthy appearance, but also improve your memory and alertness during the day.Innovations & IngredientsScience Behind the BeautyEverStrong Fortifying products are 100% vegan and sulfate-free, containing naturally derived cleansing ingredients with no harsh sulfates or salts.

A thermal inertia image has been generated over a part of Gujarat using consecutive day and night NOAA-AVHRR data. Gujarat contains two important rift basins in the western margin of India, namely, Cambay and Kutch basins. Major land covers exist in this region are alluvium, continental sediments, various rocks of Mesozoic and Cenozoic origin followed by Deccan Volcanics, tertiary and quaternary deposits. Validation of thermal inertia parameters with existing values obtained from literature indicates the efficacy of the developed technique. The study indicates that thermal inertia image can be used as a new method for geologic mapping/basin delineation where exposure is less or contrast is negligible between litho-units using traditional photography/sensing techniques.

Description

This digital document is a journal article from Forest Ecology and Management, published by Elsevier in 2005. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser.Description: Jack pine (Pinus banksiana Lamb.) and pitch pine (Pinus rigida Mill.) are two autecologically similar species that occupy generally disjunct ranges in eastern North America. Jack pine is boreal in distribution, while pitch pine occurs at temperate latitudes. The two species co-occur in a small number of stands along a 'tension-zone' that traverses central Maine. These populations provide an opportunity for studying differences between boreal and temperate species in their adaptation to climatic factors. As seedling establishment and early growth are key life-stages governing tree distribution, we experimentally evaluated the influence of seedbed light environment and substrate on the success and early growth of these species. Under similar environments, first-year jack pine seedlings allocated relatively more biomass to roots and pitch pine more to foliage. This might provide pitch pine with an adaptive advantage when soil moisture was not limiting and an advantage to jack pine if substantial moisture stress occurred. Complex ontogenetic shifts in these allocation patterns occurred over second and third years of growth, which resulted in an equalization of interspecific differences in shoot-root ratios by the end of the third growing season. Night temperatures of 4-5^oC above ambient reduced growth of jack pine seedlings, while that of pitch pine was unaffected. However, foliar respiration and respiratory response to temperature were not significantly different between species and did not explain observed differences in temperature response.
