God this show takes me back. Nice to see it again.
Are you threatening me?
Cannot be viewed outside the US. Think the US needs to be embargoed on a few things to even things out.

I See Why They're Critiquing Reality Shows in This Incarnation
by Aquatarkusman
When's the last time MTV played a music video?
can resume playing the Beavis & Butthead laughter every 5 minutes again...
It's still totally hilarious.
Oh well. At least it didn't make me sit through a fucking ad before telling me I can't watch it like a lot of these do.
...and a gringo... LOL....Always loved Cornholio....
What happened? Did Beavis go through reverse puberty? Other than that...awesome.

I thought this was really funny stuff when I was 16 or 17.
by rev_skarekroe
Nowadays, not so much.
But that shit still made me laugh.
Judge has to be pushing 50 and that can't be an easy voice to do. They might be speeding it up.
Only line in that whole clip to make me laugh.
That's pretty funny... I like Beavis and Butthead but the cornholio stuff is kind of played out.
when does this start??????
I know, strange thought, but I'm wondering if Daria ("Diarrhea, cha-cha-cha!") is going to be appearing in these new episodes. Will they be acknowledging the fact that she moved on to her own series ("Daria"), or will they just ignore it and continue to feature her? The latter would work in the sense that "Beavis and Butt-head," unlike "Daria," never acknowledged the passage of time (ala "The Simpsons"), so these new episodes could just be set in the same never-ending period of time as before. Should be interesting to see.
Made Beavis and Butthead 11 years older in this incarnation. Sadly, this just looks like more of the same, which was getting old and stale back in 1997.
Fuck off. Beavis and Butthead rocked back then, and based on the footage, still do. So tired of the Debbie Downer "should have" tards. And thank you, dvdmike, for posting the youtube link!!
Does not top the genius that is Snooki being called a "Hobbit Prostitute".
i collapse into hysterics.
Don't America bash over this. BBC does the same thing on it's sites. Can't view hardly any UK Video in the US for the same foolish copyright/export/rebroadcasting laws

No Hercules, the last time the boys were seen was Jackass 3D
by JackSlater4
I agree, there area few UK channels that do the same thing. With regards to the BBC though, the reason they do it is due to the fact that UK citizens pay a licence fee for the BBC, so basically the BBC can't show there content outside the UK for free, even if they wanted to. There actually setting up a new pay subscription service online so they can legally show content to other countries.
I meant to say there "are a few"
but I think they're doing a live action version ("Awkward") instead.
widescreen would feel so wrong

If what they end up doing is this... making fun of the shit
by MoffatBabies
they air on MTV now.... I'm there. Even though its on MTV. Oh well. Still funny.
That's right, asshole. It doesn't have anything to do with corporate distribution deals and contracts or anything like that - the reason you can't watch a Beavis & Butthead clip is because the arrogant American government, which doesn't have ANYTHING to do with making or distributing Beavis & Butthead on the interwebs, hates you and thinks its better than your backwards mud country. Fucking idiot. Save your banal, reflexive, entirely predictable and completely boring anti-Americanism for something that matters - like, for example, its illegal war in Libya.
America isn't at war with Libya? they have no troops/planes or military action going on in that country now, they support they rebel cause there that's about it. As far as i am aware it's NATO that currently has military action there.
July 22, 2011, 11:20 a.m. CST
So this means that for the fisrt time since Nov. 28, 1997
by BocephusJones
there is a reason to watch MTV again
so it sucks it's on Mtv again, but when the fuck does it start? a minor detail that would be good to know...
This show was better off dead. It's shit!
Beavis, not so much so.
July 22, 2011, 12:15 p.m. CST
So when people knock Family Guy, South Park, or other modern comedies, is this what they consider funny?
by SantiagoAndDunbar
Where the fuck have YOU been?
So is your opinion. So run and go fuck off. Step 1: If someone doesn't find something funny, don't watch it. Step 2: Do not wander into a fucking discussion about it. Step 3: Is to fuck off because comedy is seriously subjective so your "opinion as fact" stance is fucked right in the ass so I say again, run and go fuck off.
I would prefer the majority of it to be about them making fun of MTV shows rather than their adventures though. Man... this really takes me back. I remember back when my mom considered the show to be too vulgar for me to watch.
July 22, 2011, 1:57 p.m. CST
This clip is right up there, with the best of Beavis and Butthead
by jimmy rabbitte
If you don't like the show, then you shouldn't watch it; and you sure as hell shouldn't be wasting your time on a talkback board that is dedicated to said program.
Still gives me ye olde squirt-o-pee laugh.
I hope your monocle falls into your vintage wine glass.
One of the highlights of tuning into Beavis and Butthead was how they made fun of music videos. Hell, if it wasn't form B&B, White Zombie probably would not have become as popular in the '90's! Sure, Mtv long gave up on music videos (what does the M in Mtv even stand for these days?) but bands still produce videos (if not, why does Mtv still have their video music awards?) This could be a good catalyst to bring back videos to Mtv, either that or show B&B on one of the sister stations that still do!
Something good to watch on MTV again. I can't wait to see B&BH make fun of Lady Gaga and Justin Bieber.
THAT is going to be some ripe territory for B&B!!!
July 22, 2011, 5:17 p.m. CST
Fact: Beavis and Butt-Head= the reason you have South Park
by memento108
Deal with it.
Good to know my sense of humor has not progressed since I was 13.

Andrew Keegan claims the ONLY reason he was manhandled by cops at his ill-fated house party Saturday is because they wanted to make an example out of him ... even though he did nothing wrong.
The "10 Things I Hate About You" actor tells TMZ ... the event was more than a raging house party ... it was also a fundraiser for three charities ... adding, "The police chief knew about it ... I employed 5 off-duty officers."
Keegan says ... when cops approached his Marina del Rey home and asked him to turn down the music, he WAS cooperative ... even asking to speak to a sergeant "about how we can work together."
But, Keegan explains, [the sergeant] ordered 'arrest him' while my hands were in my pocket ... but they just wanted to make an example of their 'No Tolerance' Independence Day [policy].
True enough ... cops swarmed Marina del Rey and neighboring Venice, after a spike in violence, including one gang-related fatal shooting.
Keegan wasn't the only one who felt the pinch. Cops made a bunch of arrests over the long weekend ... some say to make a statement and reclaim the beach.
Sleazy little punk. How is it being cooperative when you ask to speak to a sergeant after being requested to turn your music down? You answer "yes sir/ma'am, I am sorry" and go and turn it down! You don't turn on the ooze and ask how you can work together, you just turn down the dam noise!
To all the people putting down Andrew Keegan as a noboby...please tell us what celeb lists are you on???
Thousands & thousands of people try to make it on screen even for 30 second commercials...yet never succeed...
This was a a nice glimpse in to reality of how "real people" get treated by the Police...If you are A list or politically connected.then one set of rules, kid gloves...(paris,lindsay, georgebush jr doing coke, teddy kennedy leaving a lady to drown)
But if you are perceived as just a regular citizen...one move out of line, and you get a knee in your neck... As far as gang activity control....did they think he was Blood?Crip?MS13?.
Glad this came to light. KEEP ON FILMING - only way to keep the blue mafia in check...
While they were beating up this weany actor dude, the gangs were beating,raping and robbing the rest of us.
Nothing says "freedom" like a dozen-plus taxpayer-paid thugs tasing and tackling someone over a noise complaint!!!
These cops' behavior is extremely offensive towards the ideals for which America purports to stand. It amazes me that these cops, as Americans, can actually act like they're proud of what they do. These cops, and their masquerade of authority, would be laughable if they weren't negatively affecting other people's lives and wasting so much taxpayer money.
Police officers are self entitled people with known personality types that make it so easy to abuse their power. They are isolative, prejudiced, suspicious and cynical among others. These are the traits that attract them to the job. It's amazing how many people here are so willing to bequeath them with so much power to violate out liberties. Wake up! This is America, not a police state.
The donut eating waste of tax payers money arrogant I got picked on when I was a kid so now I have a Napoleon complex cops wonder why people don't like them, jus*****ch the video!
wow!! tmz got o.g. footage of rambo with a iphone camera!! awsome job dude! brotherhood codex rules!!
It's all a scam so the cops can split the bail with the bondsman. Ask Officer Webber of the Pacific Division.
What a wanker, yep the cops chose you out of how many hundreds of people all over the neighborhood to make an example of, I bet if you asked most of the cops if they knew who you "think" you are none of them would know or care who you are
let the cops do their job, but let the media do theirs. why won't they let him film what is going on? its public record, and if it was a "crime scene" where was the yellow tape? I see two people walking by and the cops said NOTHING to them, just the one guy who is trying to catch it on tape. If the police wasn't doing anything wrong, why did they have to hide their behavior? Let the media film it as further evidence against the person you are arresting, unless you have something to hide?
I had to google him to find out who he is or of what importance he is? And for once google couldn't answer my question. Who is he?
.....He wanted to speak with the SGT, to see if they could work together??...apparently he thought his " actor " status would get him something. So, if your party is for multiple charities, that excuses you from obeying the law!...He could had been issued a ciation and released....believe me, he opened his mouth, became verbally/physically aggressive. along with others at that party or else, not that many officers would had responded.....
it's time for andrew's 10 things i hate about cops:
1. i hate it when u cuff me.
2. i hate when u shuv me.
3. i hate the way u dress, in only black
4. i hate when u grab my a$$
5. i hate it when u don't call the next day
6. i hate u never use the pink fuzzy handcuffs
7. i hate authority
8. i hate racist cops
9. i love wait i mean hate the buzz of taizers
10. but most of all i hate F%$#^ing you

U1a operates as a low-noise microphone preamp. Its gain is only about 3.9 because the high output impedance of the drain of the FET inside the electret microphone causes U1as effective input resistor to be about 12.2K. C2 has a fairly high value in order to pass very low frequency (about 20 to 30Hz) heartbeat sounds.

The 60 Watt linear amplifier is simple all solid state circuit using power mosfet IRF840. The IRF series of power transistors are available in various voltage and power ratings. A single IRF840 can handle maximum power output of 125 watts.

As a keen cyclist I am always looking for ways to be seen at night. I wanted something that was a novelty and would catch the motorists eye. So looking around at my fellow cyclists rear lights, I came up with the idea of 'NITE-RIDER'. NINE extra bright LED's running from left to right and right to left continuously. It could be constructed with red LEDs for use on the rear of the bike or white LED's for an extra eye catcher on the front of the bike.

1) IC1D is a CMOS Schmitt trigger oscillator at about 2KHz. It starts and continues to oscillate with a supply down to 1.24V (the lowest output voltage of my LM317 variable power supply) or less.
2) IC1A is an inverter.
3) IC1B is a Schmitt trigger NAND gate. Its output is low only when both inputs are at, or higher than the upper Schmitt trigger threshold voltage.

This circuit controls a load (in this case a dc brushless fan) based on a temperature compared with a setpoint. THe transduced is a diode in the forward polarization regime. In fact when forward biased, the forward voltage drop accross a diode has a temperature dependance, in particular has a negative linear(ish) slope. This because of the boltzmann distribuition, causing electrons to pass to the conduction band thermically, lowering the voltage drop accross the diode.

Multi-spark ignition is very useful especially in the case of startings at low temperature and at low rpm range. Basic idea, is to apply to spark plugs instead of only one spark, a spark-burst having big energy. In this case, combustion of air/fuel mixture is much better and the emissions are more reduced. In addition, through burning improvement, the consumption of fuel can be reduced.

If you own a motorcycle, a motor home, a caravan, a lawn mover, a day cruiser or maybe a vintage car you must at some point had to write off a lead acid battery. When a battery is improperly charged or allowed to self-discharge as occurs during non-use, sulphate crystals build up on the battery's plates.

This circuit was created for digital cameras. It's known the digital cameras have considerable power consumption. For example my camera Minolta E223 requires approximately 800 mA. In practice a mains power supply or high capacity NiMH accumulators (batteries) can satisfy this demand.

This circuit is a Logic Probe. It indicates the logic state of the node of any TTL logic circuit. To do that, we have to supply the probe with the same power of the circuit that we want to analyse: same Vcc and same GND. To check the logic level, we must connect the "Test" wire of the probe to the desired node of the circuit that we want to check.

US 3867175 A Abstract A non-fogging, abrasion resistant material is provided by applying a transparent, non-fogging coating to a normally fogging, transparent or reflecting substrate. The non-fogging, abrasion resistant coating comprises a highly cross-linked alkylene imine polymer. The polyalkylene imine may be further modified by an adhesion promoter through reaction with the amine hydrogens of the polyimine.

BACKGROUND OF THE INVENTION When a surface is at a temperature on or below the dew point of the prevailing atmosphere. water condenses on the surface in the form of small droplets. When the condensation is on transparent or reflecting surfaces it is referred to as fogging". This problem of fogging is critical for some applications and at least troublesome for many others. Substrates of plastic, glass, and metal surfaces all fog without some modification. Many attempts have been made to reduce or eliminate the fogging problem particularly for automobile Windshields and safety goggles. Early attempts included the application of films containing glycerol and more recently coatings based on hydroxy substituted acrylic polymers have been offered; see U. S. Pat. No. 3,488,215 to Shephered et al. Other coatings offered to reduce the fogging of surfaces include films containing surfactants and more recently U. S. Pat. No. 3,411,945 to Chao describes the incorporation of surfactants in the thermoplastic polymer substrate to reduce the tendency towards fogging of the surface. Accordingly, it is an object of the present invention to provide a non-fogging surface that does not interfere with the transparency or reflectance of the substrate material. An additionalobject is to provide a transparent, non-fogging coating with improved permanence, of the anti-fogging protection, increased adhesion to the substrate, improved scratch and abrasion resistance. improved durability of the adhesion to the substrate and improved durability of the surface of the coating. An additional object is to provide a transparent coating that will reduce the fogging characteristics for transparent or reflecting surfaces that may be easily applied to the surfaces to provide consistent results. A more specific object is to prepare a transparent, nonfogging coating for transparent or reflecting surfaces of glass, plastic or metal. An object is to provide nonfog ging eye lenses and protective shields, windows and mirrors. An additional object is to provide a transparent nonfogging coating for transparent substrates, particularly polycarbonate, with improved permanence'and abrasion resistance. SUMMARY OF THE INVENTION The present invention is a substrate having on at least one surface thereof a non-fogging, abrasion resistant coating comprising a polyalkylene imine (eg. polyethylene imine) cross-linked with a compound having at least two reactive groups capable of reacting with the amine hydrogen or yielding a covalent linkage to form a quaternary amine salt, to form a hard, durable, hydrophilic coating. For most substrates, the degree of crosslinking is preferably high, such that sufficient crosslinking functional compound is added capable of crosslinking the film to attain water insolubility. For certain substrates pendant reactive groups are optionally reacted to the amine hydrogens of the polyalkylene imine, the pendant groups being highly polar to promote adhesion to the substrate. The coated surface of this invention is hard and resistant to abrasion. The coating absorbs up to 50% water on the weight of the coating without optical distortion or loss of adhesion to the substrate. BRIEF DESCRIPTION OF THE DRAWINGS FIG.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The substrates most useful in this invention that are normally subject to fogging include organic polymers. particularly polycarbonate. This polymer is commonly used for shields and goggles for industrial application where fogging can constitute a safety hazard. The coated polycarbonate substrate of this invention not only offers anti-fogging characteristics but also improved abrasion resistance and mechanical properties. The non-fogging materials of this invention are normally transparent although they may be tinted such colors as amber for ski goggles. Thepolyalkylene imine useful in this invention is a well recognized class of compounds available commercially with the following repeating unit structural formula I: wherein R is substituted or unsubstituted alkylene group and n is an integer from about 2 to about 3,000. When the backbone alkylene group is ethylene, the structural formula of the repeating unit takes the form of formula II: wherein R through R are chosen from the group consisting of hydrogen and lower alkyl and n is as hereinabove. It is preferred that R through R be chosen from the group consisting of hydrogen or methyl. Particularly preferred is polyethylene imine that is prepared by polymerizing ethylene imine in acid medium. One skilled in the art will readily recognize that both formulas I and II are simplifications of the structural formula of polyalkylene imines. It is well known that this class of polymers generally forms a highly branchedrather than a linear polymer structure. As a consequence, a typical structure of polyethylene imine contains a ratio of primary to secondary to tertiary nitrogens in the polymer of approximately 112:1. This branching does not interfere with the purposes of this invention and in fact this ratio is quite satisfactory. The formulas I and Il may be considered as roughly average structures of the polymer particularly at higher molecular weights. Although the molecular weight of the polyethylene imine polymer is-not critical to the invention, the lower molecular weight range is preferred, primarily for ease of processing, handling and applying the solution to the substrate before cross-linking. The number average molecular weight (Mfi) of commercially available polyethylene imine commonly ranges from about 60 (dimer) to about 120,000, and includes dipropylenetriamine, tetraethylenepentamine, etc. Preferred are polymers with average molecular weights in the range of 300 to 60,000 and most preferred is the range of 400 to 1,000. With the higher molecular weight polyimine, the number of amine hydrogens per nitrogen atom approaches one. Theoretically, each nitrogen atom can also form a quaternary salt so that the maximum number of reactive sites per repeating unit approaches two as the molecular weight of the polyimine is increased. For the preferred lower molecular weight range the terminal groups significantly affect the number of reactive sites available for either cross-linking or attachment of pendant groups. For example, polyimine with an average molecular weight of 300 has about seven repeating units and about 9 amine hydrogens for an average of about 1.3 amine hydrogens per repeating unit. Including the quaternary salt reaction capability brings the average number of reactive sites per repeating unit to about 2.3. The coating of this invention is cross-linked by reaction with the amine hydrogens and/or through bonding to the nitrogen to form a quaternary ionic salt. The poly-functional compounds capable of cross-linking the imine polymer contain at least two groups capable of reacting with either the amine hydrogen or the nitrogen atom. Thus the compound may contain (l) at least two functional groups that react only with amine by hydrogens, e.g. divinyl benzene, (2) at least two functional groups capable of reacting with either the amine hydrogen or the nitrogen to form a quaternary salt, e.g. methylene chloride, (3) at least one functional group capable of reacting with the amine hydrogen and at least one group capable of reacting with the nitrogen to form a quaternary salt, e.g. epichlorohydrin, or (4) at least one functional group capable of reacting with the amine hydrogen to form during the reaction a secondary functional group that in turn will react with the polyimine or with another group of like type, e.g. formaldehyde. It is common to provide both cross-linking mechanisms in the same coating compositions, and it is also common to employ cross-linking compounds of more than one of the above groups. For example, the compounds of group (1) are particularly useful for chain extension reactions while the coating is in solution without gelling the product. Because of the branched nature of the polyalkylene imine polymers and the combination of cross-linking reactions taking place it is not known in which proportions the types of crosslinking reactions are taking place. The critical factor in the chemical compositions capable of cross-linking the polyalkylene imine polymers is that they contain at least two functional groups capable of either reacting with amine hydrogens or forming a covalent bond to a quaternary salt. References in the specification to amine hydrogens" include both the primary and secondary nitrogen substituted hydrogen. As a typical example, epichlorohydrin is preferred cross-linked compounds chosen from group (3) above. In this instance the cross-linking compound contains both expoxy and halogen functionality, each of which have the ability to react with the amine hydrogens on the polyalkylene imine polymers. if in the composition there are insufficient amine hydrogens to react with both the epoxy group and the halogen, the halogen can still react with the nitrogen group through the forma tion of a quaternary salt. The class of functional groups capable of these reactions is well known to those skilled in the art and includes nonaromatic ethylenic unsaturation (activated unsaturation) like vinyl, vinylene, allyl. and hutylene in such compounds as ethylene glycol, diacrylate and dimethacrylate, glycidyl methacrylate, divinyl benzene. diallyl phthalate, triallyl cyanurate, butylene glycol di acrylate, polypropylene fumarate, allyl chloride. glycidyl methacrylate, maleic anhydride. fumaric acid dichloromaleic anhydride, N,N-methylene bisacrylamide, methacrylic acid, acrylic acid, 2-chloroethyl methacrylate and the like; epoxy and epihalo in such compounds as diepoxides, epihalohydrin, particularly epichlorohydrin, glycidyl methacrylate, glycidol, low molecular weight epoxy resins such as the reaction product of epichlorohydrin and bisphenol-A, and the like; halo such as alkylene halide and aicd halide like chloro, bromo and fluoro in such compounds as methylene chloride, methylene bromide, l,2-dichloroethane, bis (2-chlorethyl) ether, epichlorohydrin, dichloromaleic anhydride, allyl chloride, 2-chloroethyl methacrylate, adipyl chloride; formyl and carbonyl in aldehydes and ketones in such compounds benzaldehyde, formaldehyde, 5,5-dimethyl-l,3-cyclohexadione, 2,5- hexanedione, dipentene dioxide and the like; carboxy and anhydride in such compounds as phthalic acids and anhydride, polyacrylic acid, glutaric acid, pyromellitic anhydride, methacrylic acid, acrylic acid, maleic anhydride, ethylene/maleic anhydride copolymers, and the like; isocyanato and isothiocyanato in such compounds as methylene bis(4-phenyl isocyanate and isothiocya nate); acidic hydroxy including phenolic hydroxy in such compounds as bisphenol-A and the like; and other functional groups that react directly or through intermediate reactions with either the amine hydrogens or the nitrogen atoms to form quaternary salts. The intermediate reactions possible are numerous in that many of the cross-linking compounds form additional functional group during the reaction with the polyimine. Some of these secondarily formed functional groups may in turn react with a polyimine or more likely react with the reaction product of another reaction with the polyiminev As an example, the reaction of glycidol with the polyimine is believed to first attach through an addition reaction of the epoxy with the amine hydrogen. A secondary reaction between two of these reaction products (each containing two hydroxyl groups) to yield a cross-link between the polyimine chains is possible, although this theory has not yet been clearly demonstrated. The term polyfunctional in describing the cross-linking compounds also includes those chemical compounds that through the reaction with the polyimine, form an additional functional group that reacts with the polyimine or the same functional group to form another site. An example of this type of polyfunctional compound is formaldehyde with which the reaction with the amine hydrogen forms a methylol group splitting out water to cross-link the imine polymerv Preferred are those cross-linking compounds containing two functional groups of at least one chosen from the group consisting of epoxy, ethylenic unsaturation and halo. The compounds containing a combination of epoxy and halogen functionality, as represented by chemical structure depicted in formula III, are particularly effective and epichlorohydrin is particularly preferred. R3124 2 1 III. Rcc-R-X where R is C, to C alkylene, R to R are each hydrogen or lower alkyl and X is halogen. The amount of cross-linking compound reacted with the polyalkylene imine depends to a degree on the choice of cross-linking compound and the particular qualities desired in addition to the anti-fog characteristics obtained through the invention. The amount of cross-linking compound generally useful to provide a durable coating is that amount necessary to effectively provide a water insoluble film coating. A preferred effective amount of cross-linking compound is that amount necessary to yield a cured coating that gains less than l007c by weight of water on the weight of the film upon immersion to equilibrium. It is commonly desirable to react all of the amine hydrogens with either the cross-linking compound above or in combination with optional pendant mono-functional groups. in fact, it is not uncommon to provide sufficient amount of cross-linking and mono-functional compounds to react not only with all of the amine hydrogens in the polyimine but provide an excess which will copolymerize or homopolymerize with the cross-linking compounds. As an example, an effective coating is that in which approximately half of the amine hydrogens on the polyimine are first reacted with acrylonitrile followed by a cross-linking reaction in which there is present not only sufficient functional groups to react with all of the amine hydrogens but an excess to react with the nitrogen to form a quaternary salt. In general, the amount of cross-linking compound is present in amounts of 0.3 to 2.5 moles per equivalent weight of the alkylene imine repeating unit in the polyimine. Preferred is an amount of,0.4 to 2.0 moles cross-linking compound per imine repeating unit in the. polymer. An amount 0.5 to 0.9 moler per imine repeating unit in the polymer is more preferred. With some substrates, it is optional to react monofunctional compounds onto the polyalkylene imine polymers that do not effectively cross-link the polymer, or alternatively, to react additional polyfunctional compounds containing at least two functional groups for reacting with the imine polymer. The preferred mono-functional compounds and polyfunctional compounds react with polyimine to form groups that are generally pendant and may be particularly effective in promoting adhesion to the substrate. These adhesion promoters are preferably reacted onto the polyalkylene imine before any reaction with the compounds functioning solely as cross-linking compounds. Of particular preference are highly polar functional groups which promote adhesion to polymeric substrates such as polycarbonate resins, acrylic polymers, and the like. These highly polar functional groups may be attached in the form of mono-functional compounds or they may be present in polyfunctional compounds which may also function as cross-linking compounds. These highly polar groups may be attached by any of the functional groups effective in the cross-linking compounds with the criticality being that at least one of the functional groups be capable of reacting with the amine hydrogens of the polyimine. For some applications, it may be preferred that the highly polar pendant groups do not react with the amine hydrogen so as not to further cross-link the polymer, but in other cases. it may be preferred to increase the hardness and mar-resistance of the coating which can be achieved by attaching the highly polar functional group in the form ofa polyfunctional compound which also acts as a cross-linking agent. The pendant polar groups include cyano, amido. acetyl, and aryl. Typical mono-functional compounds which may be reacted with the polyalkylene imine acrylonitrile, acrylamide, methacrylamide, N-alkyl acrylamides, methyl methacrylate, methyl acrylate and styrene compounds. Acrylonitrile is particularly preferred. Representative polyfunctional compounds which contain highly polar functional groups for promoting adhesion include glycidyl methacrylate and methylene-bisacrylamide. The amount of pendant polar groups reacted onto the imine polymer should still have at least about 20 mole percent of the amine hydrogens still available for cross-linking for best results. Thus, the amount of polar groups added to the composition ranges from 0 to about 80 mole percent of the alkylene imine equivalent weight of repeating unit. An excess charge ofthe modifier is possible when the reactive group has a tendancy to homopolymerize thus providing an inefficient reaction to form the polar pendant groups. A particularly effective embodiment for use on polymeric substrates contains l0 to mole percent pendant reactant per equivalent weight of imine repeating unit in the poly mer, more preferably 0.20 to 0.65 mole percent. Additional ingredients. added in minor quantities. may be included in the coating composition. These include dyes, leveling agents, and colorants which are ei ther soluble in the polymer or are dispersed in such small particle size so as not to introduce significant haze in the coating. Other typical ingredients which may be included are ultra-violet stabilizers, heat stabilizers and the like. The method of application of the coating to the substrate is not critical to the invention. It may be applied by dip coating, spray coating or roller coating. The coating composition prior to application may be prepared by any known method but best results are obtained when the solution is prepared by the scheme depicted in FIG. 7. In this method of providing fogging protection the polyalkylene imine is placed into solution, such as in water, alcohol. or water-alcohol mixture (PAI solution). Water-lower alcohol mixtures are effective and mixtures containing 1 to 25% lower alcohols are preferred. 2-propanol is most effective in the aqueous solution. If the optional adhesion promoters (polar reactant-PR), either mono-functional or polyfunctional, are to be reacted with the polyalkylene imine, it is preferred to add them to the solution before the addition of the cross-linking compounds and allow them to react with the amine hydrogens (to form PAl- PR polymer FIG. 7). Generally, as in the case of acrylonitrile, the reaction occurs spontaneously with the evolution of heat and it is only necessary to control the temperature to prevent exotherm runaway. The crosslinking chemical compounds (CL) are then added to the solution after which the substrate may be directly coated with the solution. For ease of handling, stability and best results it is preferred to allow or cause the cross-linking compound to react with the polyalkylene imine primarily as a chain extender (to form CL-PAl- PR polymer) such that it does not sufficiently cross-link the polymer to cause gel or precipitation of the polymer, preferably in the range of-about 60 to 90C for one-fourth to one-half hour. For these initial reactions the chain extension reaction is most easily carried out with low molecular weight polyalkylene imine and CL capable of reacting onlywith amine hydrogens. With the lower molecular polyimine the molecular weight of the extended polymer is more easily controlled to prevent gel. After the initial reaction with the cross-linking compound, the solution stabilizes and no further reaction takes place to gel or precipitate the polymer for a number of days. Refrigeration extends the life of the solution. After the substrate surface is coated with the solution, the coated surface (CL-PAl-PR polymer) may be immediately heated but it is preferred that most of the solvent be allowed to evaporate before heating. Temperatures to 130C, generally 60 to 120C, preferably 7090C, are used to fully Cross-link the imine polymer (PAl-PR polymer crosslinked by CL). The lower the temperature and the shorter the time the better the color of the cure coating. A nitrogen atmosphere for curing also reduces color formation. Generally to 60 minutes provides sufficient cure at the above temperature ranges. The hardness ofthe coating is controlled to a degree by the amount of heating. For many substrates only cleaning is necessary to provide good adhesion of the anti-fogging coating. However, when the substrate is particularly hydrophobic, it has been found effective to etch the surface before the coating is applied. In the case of glass the etching may be accomplished by dilute hydrofluoricc acid. With polymeric substrates, such as polycarbonate, an acid wash, which tends to oxidize and/or sulfonate the surface. is particularly effective. A solution of l to 3% by weight chromic acid in concentrated sulfuric acid gives excellent results. For example, the treatment of polycarbonate appears to make the surface hydrophilic after only a few minutes exposure. The degree of fogging protection provided by the coating is approximately proportional to the thickness of the coating. Good results are obtained when the coating is 0.5 to 3 mils or thicker, but for some uses thickness may range well outside these limits. The following examples are provided for illustration and are not intended to limit the scope of the invention. All parts and percentages are by weight unless otherwise noted. The following abbreviations are used in the examples: MM methyl methacrylate ECH epichlorohydrin PEl (numbers) polyethylene imine (approximate number average molecular weight) EO ethylene oxide AN acrylonitrilc MBA N.N-methylene bisacrylamide GM glycidyl methacrylate G glycidol S styrene lPA isopropyl acrylamide The following test procedures are used in the examples: FOGGING Qualitative determinations of resistance to fogging are made by breathing on the surface for at least ten seconds and observing whether water condenses on the surface. A plus indicates that no significant condensa tion formed on the surface. A minus indicates that condensation forms readily. Quantitative determination as indicated by Fogging Time in seconds is determined by exposure of the surface to air at 40C saturated with water vapor. The sample is conditioned for 24 hours at 50 percent relative humidity, 250C. The water saturated air is passed through a 1 /2 inch diameter tube at 1,100 cc. per minute. At the end ofthe glass tube are 1/32 inch high projections so that the sample surface can be-held against the end of the tube and still provide sufficient air flow across the surface. The Fogging Time is the time from the placement of the sample against the projections until 50 percent of the exposed circular area displays fogging. As a bench-mark, uncoated polycarbonate fogs a1- most instaneously in this test to yield a value of l or 2 seconds. A commercial anti-fogging coating offered under the HYDRON trademark by Woodstream Hydron Corporation of Litiz. Pennsylvania, believed to be described in Example 1 to IV of US. Pat No. 3,488,315 to Shepherd et a1, yields a fogging time of about 30 seconds. HARDNESS Hardness is a qualitative measure of the thumbnail hardness and general abrasion resistance of the coating. A plus indicates that the surface cannot be scratched with the finger nail and is generally abrasion resistant to handling and general use. A minus indicates that the surface can be scratched and is most applications would be abraded easily. A plus/minus indicates marginal results in some compositions. Pencil hardness commonly ranges from 2H to 4H. ADHESlON Adhesion of the coating to the substrate is determined by scribing sets of horizontal and vertical lines one-eighth inch apart to yield a grid on the surface with a razor blade, applying a piece of pressure sensitive ad hesive tape to the surface and quickly removing it. The quantitative measurement is the precent coating within the grid area lifted off. DETERGENT STABILITY The coated surface is immersed for sixteen hours in a 0.2% detergent solution at room temperature and wiped with a facial tissue. The surface quality is observed and in some instances adhesion tests are performed on the exposed samples. EXAMPLEI A lens from a safety goggle of commercially available polycarbonate resin in the shape pictured in FIG. 1 is washed in hot detergent solution, rinsed and'dried, hot washed with trichloro-trifluoroethane and dried. A coating formulation is prepared by dissolving 100 parts (2.3 equivalent weights) polyethylene imine (Mn of 600; 500-250O cps at 25C; at least 99% C H N') in ethylene glycol monoethyl ether/mixture of l-and 2- propanol (1/1) at about concentration. A charge of 55 parts AN (1 mole) is added to the solution and allowed to react. An exotherm of approximately 10C is observed. After the solution is allowed to cool to room temperature, 17 parts (0.1 mole) MBA ia added. The mixture may be heated to bring it into solution. After the solution is allowed to cool, 1 11 parts ECH (1.2 moles) are added. After the exotherm is disipated the solution is heated to 85C. After cooling and filtering the solution is clear and stable for more than 24 hours at 25C and for at least a week at 0C. The lens 2 is dipped into the solution, allowed to dry and cured in an oven at 90C for 15 to 60 minutes. The coating 3 is apparently fully cured at minutes and significant yellowing does not occur until sixty minutes. The detergent stability of the coated goggle pictured in FIGS. 1 and 2 is good with Fog Times ranging from to seconds. After detergent exposure the Fog Time is to 120 seconds with Adhesion rated adequate. EXAMPLE 2 The procedure of Example is repeated except that heat.

The AN reaction yields a temperature rise of about 12C. The solution is heated to C after the ETCH is added and after filtering a surfactant, nonyl phenyl polyethylene glycol ether, is added. The lens is etched as in Example 2 and dipped in -the coating solution. The coated lens is dried and cured for 15 to 60 minutes at C. The coatings are colorless and exhibit excellent detergent resistance. The Fog Time is 25 to 30 seconds and adhesion is 0% lift. When the etching of the lens is skipped, the surface was slightly mottled suggesting poor wetting by coating solution.

PEl (75.000) is a viscous liquid with a Brookfield viscosity of l5.000 to 25.000 cps. at 25C. While this uncross-linked imine polymer can be solution-coated on polycarbonate it is not permanent and only superficial anti-fogging characteristics are obtained. When compounds such as acrylonitrile are reacted onto the polymet, some improvement in the physical characteristics A solution of l00 parts PEl in 500 parts water is prepared. A charge of parts acrylonitrile is added and allowed to react with the attendant temperature increase. While the solution is still warm. l6 parts methylene bisacrylamide is added after which the solution is cooled to 22C. An amount of l 10 parts epichlorohydrin is added incrementally over a period of one-half hour to control the temperature rise. After the entire amount is added the solution is heated to C., then immediately cooled to 22C and filtered. The viscosity of the coating solution may be increased by reacting at 80C for 15 to 60 minutes. The solution is stable. An abrasion resistant sheet of an interpolymer of allyl diglycol carbonate/vinyl acetate/methyl methacrylate is etched with chromic acid for 90 seconds at 22C. The sheet is dipped in the coating solution prepared as above, dried and cured at 90C in air for one hour. The Fog Time is 20 seconds and the Adhesion is excellent in that there is lift in the tape tests both before and after immersion in detergent solution for 16 hours. EXAMPLE 8 The procedure of Example 1 is repeated except that the 100 parts PE1(600) is placed in solution in a mixture of water/2-propanol (8/1) before reaction with the other components. A polycarbonate lens is etched with chromic acid, rinsed, dried, and dipped into the solution. After drying the coated lens is cured at 90C for 15-60 minutes in nitrogen atmosphere, A hard, colorless coating isobtained with excellent detergent stability. At all cure times the Adhesion isexcellent. The average coating weight on the lens is 0.23 grams per lens such that a coating of approximately one mil is obtained. The equilibrium absorption of the coating at 50% relative humidity is about 15%. At 80% relative humidity the equilibrium water absorption is about 25 to 45%. At 100% relative humidity the water absorption of the coating is almost 50% without affecting the adhesion of the coating or its utility as on anti-fog coatmg. After the coating is allowed to'reach equilibrium at 50% relativehumidity and 22C, the Fog Time ranges from 50 to 70 seconds depending on the cure time. After the part is immersed in detergent solution at 22C for 16 hours and dried for one-half hour at 22C, the Fog Time is 95 to greater than 120 seconds. Even after the lens is brought to equilibrium at 80% relative humidity and 22C, the Fogging Time is still in the range of 30 to 45 seconds. The coating is unaffected after 16 hours at 60C and 78C. EXAMPLE 9 Plate glass with mirror surface quality in the shape of FIG. 3 is spray coated with the composition of Example 1. After cure at 90C., for 30 minutes a durable, fogresistant'mirror 5 obtained as pictured in FIGS. 3 and 4. The surface 6 is optically transparent and resistant to repeated washings without losing its anti-fogging property. EXAMPLE 10 A lens molded of polymethyl methacrylate of a molec ular weight of about 100,000 in the shape of FIG. 5 is dip coated in the solution as prepared under Example 1. After the coating is dried and cured for 30 minutes at 90C, an abrasion resistant, anti-fogging lens as pictured in FIGS. 5 and 6 is obtained. EXAMPLE 11 spraying application. After curing a good anti-fog coating is obtained. EXAMPLE [2 The procedure of Example 8 is repeated except that the following components are used in the coating: EXAMPLE 1 3 A solution of an uncured resinous composition is prepared by dissolving 13.6 parts PE1(600) in 25 parts distilled water. A charge of 0.6 parts MBA is then dissolved in the solution followed by the gradual addition of 7.2 parts GM during which time the solution exotherms to about 60C. While maintaining the solution at about 60C, 4.0 parts ECH is added followed by the addition of4.0 parts 2-propanol. The solution is heated to 68C for 30 minutes and then immediately cooled to 25C over a period of 30 minutes. The solution is stable at ambient temperatures for at least 6 months. The solution is dip-coated on substrates including polycarbonate, glass and a sheet of an interpolymer of allyl diglycol carbonate/vinyl acetate/methyl methacrylate and then cured for 30 to 60 minutes at C in a hot air oven. The coatings are all resistant to fogging and yield 0% lift in the adhesion test after detergent solution soaking.

Watch Out: Barbarians At The Gate For Palo Alto Networks (PANW)
Editor's Note: Any reference to TheStreet Ratings and its underlying recommendation does not reflect the opinion of TheStreet, Inc. or any of its contributors including Jim Cramer or Stephanie Link.Trade-Ideas LLC identified Palo Alto Networks (PANW) as a "barbarian at the gate" (strong stocks crossing above resistance with today's range greater than 200%) candidate. In addition to specific proprietary factors, Trade-Ideas identified Palo Alto Networks as such a stock due to the following factors:
- PANW has an average dollar-volume (as measured by average daily share volume multiplied by share price) of $34.5 million.
- PANW has traded 1.6 million shares today.
- PANW traded in a range 289.8% of the normal price range with a price range of $3.07.
- PANW traded above its daily resistance level (quality: 30 days, meaning that the stock is crossing a resistance level set by the last 30 calendar days. The resistance price is defined by the Price - $0.01 at the time of the signal).
Stocks matching the 'Barbarian at the Gate' criteria are worthwhile stocks to watch for a variety of factors including historical back testing and volatility. Trade-Ideas targets these opportunities because the stock is exhibiting an unusual behavior while displaying positive price action. In this case, the stock crossed an important inflection point; namely, 'resistance' while at the same time the range of the stock's movement in price is more than twice its normal size. This large range foreshadows a possible continuation as the stock moves higher.EXCLUSIVE OFFER: Get the inside scoop on opportunities in PANW with the Ticky from Trade-Ideas.

Learn more.TheStreetRatings.com Analysis:TheStreet Quant Ratings rates Palo Alto Networks as a sell. The company's weaknesses can be seen in multiple areas, such as its deteriorating net income, generally disappointing historical performance in the stock itself and feeble growth in its earnings per share.Highlights from the ratings report include:
- The company, on the basis of change in net income from the same quarter one year ago, has significantly underperformed when compared to that of the S&P 500 and the Communications Equipment industry. The net income has significantly decreased by 244.3% when compared to the same quarter one year ago, falling from -$4.60 million to -$15.84 million.
- The share price of PALO ALTO NETWORKS INC has not done very well: it is down 23.40% and has underperformed the S&P 500, in part reflecting the company's sharply declining earnings per share when compared to the year-earlier quarter. The fact that the stock is now selling for less than others in its industry in relation to its current earnings is not reason enough to justify a buy rating at this time.
- PALO ALTO NETWORKS INC has experienced a steep decline in earnings per share in the most recent quarter in comparison to its performance from the same quarter a year ago. The company has reported a trend of declining earnings per share over the past year. However, the consensus estimate suggests that this trend should reverse in the coming year. During the past fiscal year, PALO ALTO NETWORKS INC reported poor results of -$0.41 versus -$0.06 in the prior year. This year, the market expects an improvement in earnings ($0.42 versus -$0.41).
- Compared to other companies in the Communications Equipment industry and the overall market, PALO ALTO NETWORKS INC's return on equity significantly trails that of both the industry average and the S&P 500.
- The gross profit margin for PALO ALTO NETWORKS INC is currently very high, coming in at 75.45%. It has increased from the same quarter the previous year. Regardless of the strong results of the gross profit margin, the net profit margin of -14.09% is in-line with the industry average.

The environmental Kuzents Curve and the role of coal consumption in India: cointegration and causality analysis in an open economy
This study investigates the dynamic relationship between coal consumption, economic growth, trade openness and CO2 emissions for Indian economy. In doing so, Narayan and Pop structural break unit test is applied to test the order of integration of the variables. Long run relationship between the variables is tested by applying ARDL bounds testing approach to cointegration developed by Pesaran et al. (2001). The results confirm the existence of cointegration for long run between coal consumption, economic growth, trade openness and CO2 emissions. Our empirical exercise indicates the presence of Environmental Kuznets Curve (EKC) long run as well as short run. Coal consumption as well as trade openness contributes to CO2 emissions. The causality results report the feedback hypothesis between economic growth and CO2 emissions and same inference is drawn between coal consumption and CO2 emissions. Moreover, trade openness Granger causes economic growth, coal consumption and CO2 emissions.Download Info
