Shrimp and Artichoke With Pasta
Recipe by cookiedog
This is wonderful served with a green salad and some french bread. Using peeled shrimp cuts down on the prep time. Don't be afraid to add a good sized pinch of the cayenne- it rounds out the flavors. I was originally going to submit this to RSC 11. This recipe is a result of NcMysteryShopper's great ingredient list.
Top Review by CabinKat
I made this in hopes that it would be simular to the shrimp & artichoke pasta served at Side Tracks in Burlington, NC. However, it was not. My BH just loved it nonetheless. I personally felt it was missing something. A bit more spice perhaps or a suggestion of adding sundried tomatoes in step 3. I will say that it was easy and I may consider it again with an add-in of my own taste. Thanks for posting cookiedog!

Englemere Pond
Englemere Pond Nature Reserve covers an area of 27.6 Ha (68.2 acres) and consists of a shallow acidic lake offering a wide range of habitats that are important for wildlife. The site, which is located off Swinley road in Ascot, is extremely popular with dog-walkers, ramblers and nature lovers.
Englemere Pond is featured in the Great Places for Circular Walks booklet.
Facilities and key features
- a site noticeboard containing general site/wildlife information and temporary notices
- a circular marked nature trail that starts and ends at the car park
- a bench near the pond which serves as an excellent bird observation point
For much of its recorded history the site has been part of a great Royal Hunting Forest that surrounded Windsor Castle and today it is still part of the Crown Estate.
The site is designated a Site of Special Scientific Interest (SSSI) and a Local Nature Reserve (LNR) for its important range of habitats and associated species. Open water and marshes are surrounded by commercial forest and heathland areas, each of which provide their own variety of plant species and a home for many birds, insects and animals.
The reed bed and shallow lake is important for many specialised birds and insects including grass snakes and the boggy areas are important for round-leaved sundew, a plant listed in the borough's Biodiversity Action Plan.
Englemere Pond is managed under a licence agreement by Bracknell Forest Council.
The site is being enhanced as a Suitable Alternative Natural Greenspace (SANGs) in order to create an enjoyable natural environment for recreation, away from the Thames Basin Heath Special Protection Area.
The Scots pine woodland is managed as a timber crop by The Crown Estate. Oak, mountain ash, willow and silver birch are also to be found here and alder trees are a favourite haunt of wintering migrant birds, such as siskins and redpolls who feed on the seeds.
How to get there
Located in Ascot, and in the parish of Winkfield the site can be accessed via Englemere car park, Swinley road, Winkfield, SL5 8BA. Grid reference SU905685.
If you are on foot you can access the park from Swinley Road, along the London Road by the traffic lights at the junction with Fernbank Road and further along the London Road towards Ascot via a narrow gap beside a locked metal field gate.
Sleeper bridges and boardwalks have been installed and surfacing has been provided in particularly wet areas of the trail.

Ben or anyone on the list,
Hi, I have been lurking for quite a while. I have enjoyed all of the
information and the games, too.
I, too, saw the show on HGTV last Saturday on Ed Skrocki and his
semps. I have tried to find out if he sells plants mail order or through any
mail order nurseries, but cannot find any information on him. I tried
www.google.com and found references to his plants, but nothing on him. I
tried www.qwestdex.com (our local phone company online directory) and put in
his name, city and state and found nothing. I think the show was a couple of
years old. Is he still alive? Is he still active in the semp community? I
would really like to buy some of his plants. (especially the orange one! If
he has any available) Any help would be greatly appreciated.

A Teaspoon
Soooooo, i think about food alot...
Frosting. You can't detect the malevolence of frosting when you're a child. There's nothing appalling about it, the way, conversely, a raspberry can make you pucker. In the rawness of it, nothing is yet pacified. And so, you play the purist all those years, accepting the sourness of it as a small shortcoming to an otherwise perfect piece of fruit.
And then with frosting, every inch of it is pacified, tamed, so that it doesn't scare you the way a brave hunk of woody, unripe plum can. You know that feeling. It's the same dread of waking up to the fluorescent light, the acridity of coffee in the morning. Straddling the toilet seat in the dead of winter for fear of that cruel shock.
Frosting was a place where none of that existed. I loved the tender sweetness of it, the sheer comfort, and the liberal way they loaded it on a cupcake. Best of all, I loved watching its swirling transformation from white to robin's egg blue or buttercup yellow when spotted with a teaspoon of colouring. It didn't take much to make it so, and yet the effect was striking.
It seemed too good to be true, at the time. I used to imagine the global shortage of butter cream frosting, poor children sitting down to English tea, a stingy cupcake upon a saucer, because I had hoarded it all. But I didn't lose any sleep over it. I adored frosting…
Until now, whereupon the sight turns my stomach. When you're little, you're too stupid to feel it killing you, or perhaps you're stronger. I can't tell which. All I know is that the sentiment towards confection is not what it was following the first decade and a half of my life, and I began to taste something ironic in it. The sick sweetness is all wrong- the powdery backdrop, ghostly.
And ghosts, I've had it with ghosts. Not the phantom of Grandad striding out of my closet. The ghost between what someone says and what they mean to say.
Maude: "I hear the French like to blanch their peaches. The skins peel easier, dontcha know?"
Ghost Maude: "That's how you skin a peach. Give me that."
Maude is from my Sunday Bake Exchange, if you want to know. It's what we do when our Johns and Walters and Billys are out at some buddy's pad, a scotch in hand, and they're playing Rummoli. The women seem to enjoy it. To me, it seems more like an I don't need you statement. Proof that I also have people in my life, though friends might be stretching it. Sunday saves me from lulling into insanity.
We take turns each week as the hostess of the exchange. I like to be the hostess because that way, I get to show off my fine china and my Blue Willow set, and nobody says a word. Silence, here, means that I've impressed them all- a satisfying feat.
First, we allow something close to ten minutes for any latecomers. Beth is always late.
"Well good afterNOOOON ladies, I'm sure sorry for bein' late an all, caught myself dusting the vacuum. Some things have just GOT to be done, you know how it is."
Last week she told us she'd been vacuuming the dust.
Second, the hostess sets up coffee and tea and the ladies distribute plates and dessert forks while, one by one, they give a short description about the dish they made. Not everyone brings something, which is good for various reasons. It's a real nuisance when two ladies bring the same item. Then we get into superiority issues (Example: Cake A had a tighter crumb, but Cake B had a prettier piping job). Another thing is, I get a little sick of sugary treats, especially nanaimo bars, which usually find themselves squashed in a napkin (discreetly) rather than in my stomach. Once, the buttery parcel exploded in my handbag, and I had to toss it out, it was so sticky. I guess it served me right. It's refreshing when someone brings something savoury, like a loaf of artisan bread, instead of sweetmeats and cake. Then I don't have to worry about hiding it in my lap like a child would do.
Third, a volunteer stands at the head of the table and leads grace. This one's easy, but I've always found it a shade embarrassing, because our improvised compositions usually go a little something like this:
"Lord, we give you thanks and praise, as we gather here in May's fine abode, and we proclaim our gratefulness for providing us with these plentiful ingredients. Lord, the St. Augustine Sunday Bake Exchange Group is blessed by your salvation. Amen."
And fourth, we dish out the confections, and we temper it with threads of small talk and weak conversation topics.
"Oh, May! You got that new 2- quart KitchenAid stand mixer, beauty!"
I watch Estelle's beehive sway up and down, side to side, half wishing it would unravel into a sandy heap around her neck. It's tight with bobby pins, though, and the hairspray holds it snug like stiff Italian meringue.
"I was at an auction last month, you know, for the United Way volunteers, and I had my eye on a beaut, just like yours, only a 5-quart, and it was this delicious avocado green. Had to have it." I'm transfixed by the red circle of her mouth, contracting and fluctuating as she speaks. "Oh, but that plain white is just swell, make no mistake. Simple is best, yunno?"
"Oh, Estelle! Did you not read that article in The Baker's Digest? They said the dye for that avocado colour is defective. There's an ingredient in it, I don't know the specifics, but there's some sort of cancer-causing agent in it. No guff! It's out in the open, and it becomes airborne, and ugh, I hate to even think of it. You're gonna want to say farewell to that thing PDQ!"
The other draft of my retort was better, but I didn't use it: Oh, Estelle? Why don't you bring over your big beautiful KitchenAid so ours can have a pissing contest?
"Mmm," she scrunches her nose. "I wouldn't know it. I'm on to Chops Weekly, now. I find the articles slightly more sophisticated."
"Do you."
I sense it's time to end this before it gets hairy.
Ghosts are everywhere. These are the ones I'm talking about. A room full of women at a baking exchange is really a room full of ghosts. We wade knee deep in pride, and our sole aim is to rise up through the mush of silly women as the cleverest, baking-est woman of all. It's not about the food or the sharing of the food or the company of the sharing of the food. It's not about keeping family traditions alive. It's about proving resourcefulness as a woman, how well mother taught you. It's about streamlining technique to get the most out of as little as possible. Finding the single most efficient stroke that binds the mess together in one clean 'whup'. It's about relishing in the victory of showing them all how. Climbing up the invisible ladder. Raking in the virtual points. It's about developing the cleverest culinary tips and calling them your own.
At least, of course, if you ask me.
Anyway, I have a notebook full of these culinary shortcuts. They're the fruits of my labour in the kitchen. Hours upon hours have been invested, measuring quarts shattered in frustration. I think I've broken three so far, but I'm not sure. I'm like a researcher looking for the cure for AIDS, only this time I'm doctoring flour, molasses and lard. It's what women do all day at home when their Arthurs and Eliots and Franks are at work.
Here are some examples:
-Save the aluminium wrapping from the butter block, and use it to smear it all over the baking dish for an even, non-stick coating. For even better non-stick, drop a spoonful of flour into the buttered dish, and give it a good shake about until it clings to all sides.
-If you run out of brown sugar, all you have to do is add a tablespoon of molasses to plain white sugar and give it a good strong mix. Or, if your brown sugar goes dry and brittle, stick a slice of bread into the container. By tomorrow, it will be moist and supple like new.
-If you run out of buttermilk, add a teaspoon of lemon juice or white vinegar to regular milk, and it will curdle.
-Use cornflakes instead of breadcrumbs for fried poultry. It costs less, contains less sodium, and makes a nice crunchy texture.
-Use an ice cream scoop for drop cookie dough. It dispenses consistently and efficiently.
-If a large bag of marshmallows have already been opened, freeze them. Otherwise, they dry and shrivel over time.
-Prepare the lattice for a pie on a baking sheet. Freeze it, and then place it over the pie for trouble-free transfer.
-Use a serrated knife for chopping baker's chocolate. That way, it stays stationary when you cut it, and doesn't end up on the floor.
-To prevent the unsightly green tinge that a hardboiled egg gets prior to cooling, immerse the eggs in an ice-water bath once they're out of the boiling water.
The embarrassing ones, I don't write down. I keep them in my head. Like the way I'll add half the box of Betty Crocker's yellow cake mix to the batter I'd been making from scratch. That way, it tastes professional and chemically modified the way it should. That's what we're all aiming for, anyway. It's a weasel trick, but I gain virtual points.
"May, this is fantastic! Is this really from scratch? You little devil, it's from the box!"
"Cross my heart and hope to die."
"Well I'll be."
Then I laugh my favourite, melodic laugh so Estelle can hear me.
This week, I've really outdone myself. I spent hours last night making an Ancient Egypt themed cake, and it looks incredible, like one of those custom-made cakes you only order for a bar mitzfa or a chic New York after party. The icing on top is the colour of sand, and an even stream of blue gelatin that is supposed to be the Nile meanders all over the top. Then the three great pyramids stand together at one end, and they're made of soft Werthers Toffee cut into rough cubes because they have the right colour. I even made a sphinx in the centre out of marzipan, which costs a small fortune if you make it from scratch like I did. And in places that were bare, I piped (very steadily) pictures of Isis and Orisis, and hieroglyphics where it made sense. For this, I had to visit the library for books on Ancient Egypt.
This time, I used my half-and-half weasel trick again, where I add half the store-bought mix. I'm scared that Estelle will point this out to everyone. She always finds a way to dampen my glory, but I'm doing my best not to give her that chance, because my Ancient Egypt inspired cake is almost flawless.
Lulu the Korean lady helps me haul it to the middle of the table, and all the ladies erupt into praise. I smile so much my jaw aches, but I can't help it.
"Ohhh mmmmyyy…" "Loook at thaaaaaaat…" "Ohh, Maaaaaaay…"
"Oh lord, look at that piping job… just flawless…"
"Is that… marzipan? From scratch? Get out of town! Marsha, remember we made marzipan? Organic peanut butter is what it tasted like. Ha!"
"And she's a sculptor! Just look at the detail of her sphinx."
"You made that out of gelatin? How on earth-?"
"The Pyramids of Giza! How cute!"
Praise is lovely, but it makes me a little uncomfortable.
"Oh, stop it…" I say to retain some modesty.
"May, how long did this take you?"
"Oh, two to three hours. Not terribly long."
Meanwhile, I'm keeping an eye on Estelle. She hasn't said a word yet, but there's a faint smirk on her face. I'm scared at whatever she's doing that for. What've I done wrong? It's not my piping, it's perfect.
"I couldn't bear to cut the thing!"
"Oh, I know, it's a work of art! Who's gonna do it?"
My sphinx is the masterpiece, and it shimmers a little because I dusted some of that golden powder on it that the big chefs use for decoration.
"Maybe if we try to avoid the sphinx and the Pyramids, and go for the flat bits…"
"Oh! I'll run and get my Kodak. It's only across the street, I won't keep you."
Is it the navy blue icing on the sides? Did I choose a dumb colour? I knew I should've kept it simple…
"Alright, ladies, let's get some plates going." They're cutting it into squares and passing it down, taking in the aroma, and Estelle is sitting straight now and expressionless with all the ambivalence of a judge. What if she finds out about my cake batter cheat?
"Tastes as good as it looks, Mayflower." I can handle Lulu.
Everyone gets a piece now. Estelle gets one too, and I watch her chew it slowly and thoughtfully. She's looking at my three pyramids, side to side, and then she smiles.
"You used Werthers Toffees, and then you stacked them. How charming, May."
So it wasn't the batter, and it wasn't the navy blue. It was the pyramids. What I say next comes without thinking, and I splutter, wild-eyed, like a maniac.
"Yeah, well you must think I'm stupid if you use store-bought frosting, you dirty cheater. Everyone knows."
The chatter stops immediately, and the ladies look from myself, to Estelle, to myself again. To my amazement, Estelle looks almost hurt, staring at me, her eyebrows inverted. She looks down in her lap, and Lulu pipes up.
"What did you say this time, Stella?"
More silence. I realize my fist has been on the table all along, and my lip curled. I withdraw from both and stare at the plaster ceiling. He doesn't have anything to say, either. I wonder what my husband is doing right now.
"Hey, now, Stella was just bein' gentle," a lady offers.
I figure that out now.
I hear the droplets from the sink strike the porcelain, offering a cheer up melody.
The ladies are trying to patch up where they left off.
"Well anyways, May, this is just darling. You could start a baking career on this sort of thing."
"You know that shop down by the lakeshore, run by the old English woman? She designed a medieval cake for my son's birthday."
"Oh, I know the one! She's still going? I reckoned she was on her last legs!"
I'm still concentrated on the ceiling, trying to think about cake. Salty tears sting my eyelids at first, and then more come and roll down my face and into my ears because I'm looking up.
"She makes a fortune, too. That business has been going strong since I moved here fifteen years ago."
"I'll bet she does! Maybe our May here could be her assistant! How about it May?"
Suddenly, a great, horrible sob breaks loose, and I sound like Kathleen Turner, the way I'm wailing. I cannot stop, and I'm sure I look like a red baby.
"Oh, May…" Lulu puts a hand on mine, but I pull away and walk to the kitchen doorway.
It's silent again, until Estelle says "Well, I'd best be on my way."
A murmur of agreement follows, and one by one, I watch the ladies abandon my partially eaten Ancient Egypt themed cake and exit through the front door as I continue to sob. When they're all gone, I sink down to the floor and feel that the tile is sticky because it's a hot summer day. From the floor, I glance at my cake with disgust, and then turn away.
Sometimes, you're off by a little, and it makes all the difference. Even by the margin of a teaspoon.
Crying into my ears and my hair, I fall asleep on the tile floor.

The role of two volatile sesquiterpenes, (E)-beta-farnesene and (-)-beta-caryophyllene, in the chemical ecology of the multicolored Asian lady beetle, Harmonia axyridis Pallas, was investigated by using both electrophysiological and behavioral techniques. (E)-beta-Farnesene is the major component of the alarm pheromone of most aphid species, which are preyed on by H. axyridis. (-)-beta-Caryophyllene was previously isolated from the headspace volatiles above overwintering and aggregated H. axyridis females. These sesquiterpenes elicited significant electroantennogram (EAG) activity from both H. axyridis male and female antennae. In a four-arm olfactometer, male and female H. axyridis were highly attracted toward (E)-beta-farnesene, whereas only males were attracted to (-)-beta-caryophyllene. In a bioassay technique that used a passively ventilated plastic box, both male and female H. axyridis aggregated in the (-)-beta-caryophyllene-treated side of the box. These results support the potential usefulness of (E)-beta-farnesene and (-)-beta-caryophyllene in push-pull strategies that use H. axyridis as a biological control agent in aphid-infested sites or to control this new urban pest in residential structures.

Soon after death, carcasses release volatile chemicals that attract carrion insects including Silphidae. Nevertheless, it is not known which chemical cues are involved in the attractiveness of the carcass. So far, little information is available on the chemical ecology of carrion beetles, particularly concerning the subfamily of Silphinae. The biological role of selected cadaveric volatile organic compounds including: dimethyldisulfide (DMDS), butan-1-ol, n-butanoic acid, indole, phenol, p-cresol, putrescine, and cadaverine on the silphine species, Thanatophilus sinuatus Fabricius, was investigated by using both electrophysiological and behavioural techniques. Among the tested cadaveric compounds, butan-1-ol and DMDS elicited the strongest EAG from both T. sinuatus male and female antennae. In a two-arm olfactometer, males and females were significantly attracted to dimethyldisulfide (DMDS) for both tested doses, whereas only males were attracted to p-cresol at 100 ng. Putrescine was repellent to males at the dose of 1 µg [less ▲]Detailed reference viewed: 214 (28 ULg)

We have recently shown that the alkaloid methyl-laudanosine blocks SK channel-mediated afterhyperpolarizations (AHPs) in midbrain dopaminergic neurones. However, the relative potency of the compound on the SK channel subtypes and its ability to block AHPs of other neurones were unknown. Using whole-cell patch-clamp experiments in transfected cell lines, we found that the compound blocks SK1, SK2 and SK3 currents with equal potency: its mean IC(50)s were 1.2, 0.8 and 1.8 microM, respectively. IK currents were unaffected. In rat brain slices, methyl-laudanosine blocked apamin-sensitive AHPs in serotonergic neurones of the dorsal raphe and noradrenergic neurones of the locus coeruleus with IC(50)s of 21 and 19 microM, as compared to 15 microM in dopaminergic neurones. However, at 100 microM, methyl-laudanosine elicited a constant hyperpolarization of serotonergic neurones of about 9 mV, which was inconsistently (i.e. not in a reproducible manner) antagonized by atropine and hence partly due to the activation of muscarinic receptors. While exploring the pharmacology of related compounds, we found that methyl-noscapine also blocked SK channels. In cell lines, methyl-noscapine blocked SK1, SK2 and SK3 currents with mean IC(50)s of 5.9, 5.6 and 3.9 microM, respectively. It also did not block IK currents. Methyl-noscapine was slightly less potent than methyl-laudanosine in blocking AHPs in brain slices, its IC(50)s being 42, 37 and 29 microM in dopaminergic, serotonergic and noradrenergic neurones, respectively. Interestingly, no significant non-SK effects were observed with methyl-noscapine in slices. At a concentration of 300 microM, methyl-noscapine elicited the same changes in excitability in the three neuronal types than did a supramaximal concentration of apamin (300 nM). Methyl-laudanosine and methyl-noscapine produced a rapidly reversible blockade of SK channels as compared with apamin. The difference between the IC(50)s of apamin (0.45 nM) and methyl-laudanosine (1.8 microM) in SK3 cells was essentially due to a major difference in their k(-1) (0.028 s(-1) for apamin and >or=20 s(-1) for methyl-laudanosine). These experiments demonstrate that both methyl-laudanosine and methyl-noscapine are medium potency, quickly dissociating, SK channel blockers with a similar potency on the three SK subtypes. Methyl-noscapine may be superior in terms of specificity for the SK channels. [less ▲]Detailed reference viewed: 133 (32 ULg)

The existence of normal sleep in patients in a vegetative state is still a matter of debate. Previous electrophysiological sleep studies in patients with disorders of consciousness did not differentiate patients in a vegetative state from patients in a minimally conscious state. Using high-density electroencephalographic sleep recordings, 11 patients with disorders of consciousness (six in a minimally conscious state, five in a vegetative state) were studied to correlate the electrophysiological changes associated with sleep to behavioural changes in vigilance (sustained eye closure and muscle inactivity). All minimally conscious patients showed clear electroencephalographic changes associated with decreases in behavioural vigilance. In the five minimally conscious patients showing sustained behavioural sleep periods, we identified several electrophysiological characteristics typical of normal sleep. In particular, all minimally conscious patients showed an alternating non-rapid eye movement/rapid eye movement sleep pattern and a homoeostatic decline of electroencephalographic slow wave activity through the night. In contrast, for most patients in a vegetative state, while preserved behavioural sleep was observed, the electroencephalographic patterns remained virtually unchanged during periods with the eyes closed compared to periods of behavioural wakefulness (eyes open and muscle activity). No slow wave sleep or rapid eye movement sleep stages could be identified and no homoeostatic regulation of sleep-related slow wave activity was observed over the night-time period. In conclusion, we observed behavioural, but no electrophysiological, sleep wake patterns in patients in a vegetative state, while there were near-to-normal patterns of sleep in patients in a minimally conscious state. These results shed light on the relationship between sleep electrophysiology and the level of consciousness in severely brain-damaged patients. We suggest that the study of sleep and homoeostatic regulation of slow wave activity may provide a complementary tool for the assessment of brain function in minimally conscious state and vegetative state patients.

Monoaminergic neurons have been shown to play a role in both the intoxicating and chronic effects of ethanol. We present here the results of a study about the acute effects of ethanol on serotonergic raphe nucleus, noradrenergic locus coeruleus, and dopaminergic ventral tegmental area. These nuclei were investigated electrophysiologically by recording the spontaneous firing rate of single neurons using glass microelectrodes, both in vivo in chloral hydrate anesthetized rats and in vitro in brain slices. Ethanol was perfused intravenously at a rate ranging from 0.2 mg/kg/min to 0.2 g/kg/min in vivo, and at concentrations between 10(-8) M and 1 M in vitro. We observed that each monoaminergic nucleus had its own pattern of responses to acute ethanol perfusion, and that high and low concentrations have different actions, suggesting a biphasic effect. For example, in slices, ethanol concentrations higher than 10 mM induce an excitation in most raphe and ventral tegmental area neurons, and an inhibition of firing in locus coeruleus neurons. The results were comparable in the in vivo model, but much more heterogenous. We conclude that the effect of ethanol on the monoaminergic neurons is specific of the type of neuron, and that a biphasic effect is commonly found. [less ▲]Detailed reference viewed: 21 (3 ULg)

Electroencephalographic activity in the context of disorders of consciousness is a swiss knife like tool that can evaluate different aspects of cognitive residual function, detect consciousness and provide a mean to communicate with the outside world without using muscular channels. Standard recordings in the neurological department offer a first global view of the electrogenesis of a patient and can spot abnormal epileptiform activity and therefore guide treatment. Although visual patterns have a prognosis value, they are not sufficient to provide a diagnosis between vegetative state/unresponsive wakefulness syndrome (VS/UWS) and minimally conscious state (MCS) patients. Quantitative electroencephalography (qEEG) processes the data and retrieves features, not visible on the raw traces, which can then be classified. Current results using qEEG show that MCS can be differentiated from VS/UWS patients at the group level. Event Related Potentials (ERP) are triggered by varying stimuli and reflect the time course of information processing related to the stimuli from low-level peripheral receptive structures to high-order associative cortices. It is hence possible to assess auditory, visual, or emotive pathways. Different stimuli elicit positive or negative components with different time signatures. The presence of these components when observed in passive paradigms is usually a sign of good prognosis but it cannot differentiate VS/UWS and MCS patients. Recently, researchers have developed active paradigms showing that the amplitude of the component is modulated when the subject's attention is focused on a task during stimulus presentation. Hence significant differences between ERPs of a patient in a passive compared to an active paradigm can be a proof of consciousness. An EEG-based brain-computer interface (BCI) can then be tested to provide the patient with a communication tool. BCIs have considerably improved the past two decades. However they are not easily adaptable to comatose patients as they can have visual or auditory impairments or different lesions affecting their EEG signal. Future progress will require large databases of resting state-EEG and ERPs experiment of patients of different etiologies. This will allow the identification of specific patterns related to the diagnostic of consciousness. Standardized procedures in the use of BCIs will also be needed to find the most suited technique for each individual patient. [less ▲]Detailed reference viewed: 334 (7 ULg)

Migraine is an ictal disorder characterised by a particular vulnerability of patients to sensory overload, both during and outside of the attack. Central nervous system dysfunctions are supposed to play a pivotal role in migraine. Electroneurophysiological methods, which aim to investigate sensory processing, seem thus particularly appropriate to study the pathophysiology of migraine. We have thus reviewed evoked potential studies performed in migraine patients. Although results are in part contradictory, these studies nonetheless demonstrate an interictal dysfunction of sensory cortices, and possibly of subcortical structures, in migraine with and without aura. The predominant abnormality is a deficient habituation of evoked responses to repeated stimuli, probably due to cortical, and possibly widespread neural, "dysexcitability".

Electrophysiological methods may help to unravel some of the pathophysiological mechanisms of migraine. Lack of habituation is the principal and most reproducible interictal abnormality in sensory processing in migraineurs. It is found in evoked potential (EP) studies for every stimulation modality including nociceptive stimuli, and it is likely to be responsible for the increased intensity dependence of EP. We have hypothesized that deficient EP habituation in migraine could be due to a reduced preactivation level of sensory cortices because of hypofunctioning subcortico-cortical aminergic pathways. This is not in keeping with simple hyperexcitability of the cortex, which has been suggested by some, but not all, studies of transcranial magnetic stimulation (TMS). A recent study of the effects of repetitive TMS on visual EP strongly supports the hypothesis that migraine is characterized by interictal cortical hypoexcitability. With regard to pain mechanisms in migraine, electrophysiological studies of trigeminal pathways using nociceptive blink and corneal reflexes have confirmed that sensitization of central trigeminal nociceptors occurs during migraine attacks.

Death and CircumstanceMature
I almost forgot my purpose. I wondered if she really saw me, or if her eyes had simply wandered in my direction.
"Where are you taking him?" Her voice was free of all emotion and of all reason. "I mean, where is he going?"
That's the question I imagined they would ask if they could.
And I'm nearly never wrong.
I couldn't answer her. They don't tell us things like that, if you're wondering.
Her face remained resolute as she stroked the face of Andre's soul. "This is the second one you've taken from me." Her voice was rough but quiet.
Ashamed, I turned away from her. My job here was done.
My job is done. My job is done.
I refused to look into her eyes again.
They say that Death is heartless.
That may be, but Jeff has a heart, indeed.

Gale explains why international negotiations have not produced a sustainable solution to tropical rainforest degredation. Using an innovative, critical approach to international regimes, the author analyzes the structure and operation of the International Tropical Timber Organization (ITTO). He shows how the timber industry and producing- and consuming-country governments created a blocking alliance that favoured developmentalist interests and ideas. The ITTO bolstered this alliance by permitting environmentalists merely to voice, but not to negotiate, their concerns.

rely upon a second entity to execute a set of actions and/or make a set of assertions about a set of subjects and/or scopes" - WS-Trust Specification Specification released December 2002 by Microsoft, IBM, Verisign, and RSA Security In order to secure a communication between 2 parties, the 2 parties must exchange security credentials (either directly or indirectly) However, each party needs to determine if they can "trust" the asserted credentials of the other party 33 A "Trust Engine" is a conceptual component of a Web service that evaluations the security-related aspects of a message A Trust Engine performs the following functions: Verifies that the claims in the token are sufficient to comply with the policy and that the message conforms to the policy Verifies that the attributes of the claimant are proven by the signatures Verifies that the issuers of the security tokens are trusted to issue the claims they have made 34 A "Security Token Service" is a Web service that issues security tokens based on trust Transmission using Trust Engine and Secure Token Service: Sender Trust Engine Receiver Trust Engine Security Token Service 35 Some XML Examples Requesting/returning a

Specification: http://msdn.microsoft.com/ws/2002/12/ws-trust 37 Potential E-Government Applicability May have applicability to E-Government initiatives (such as Federal Asset Sales) for issuance of security tokens to users based on trust requirements Ex: State Agencies for Surplus Property (SASP) that receive donated property 38 WS-Routing 39 WS-Routing is a simple, stateless, protocol for routing SOAP messages over a variety of transports such as TCP, UDP, and HTTP Entire path for a SOAP message (as well as its return path) can be described directly within the SOAP envelope Specification released October 2001 by Microsoft Protocols such as HTTP and SMTP define their own message path models and message exchange patterns that differ from the SOAP message model Not possible to use these protocol bindings alone to describe the exchange of a SOAP message from one point to another SOAP Router – a SOAP node that exposes SOAP message relaying as a Web service, either as a standalone service or in combination with other services 40 An XML Example Specifying intermediaries: Messages from A to D will pass through B and C <SOAP-ENV:Header> <wsrp:path> <wsrp:action>http://www.im.org/chat</wsrp:action> <wsrp:to>soap://D.com/some/endpoint</wsrp:to> <wsrp:fwd> <wsrp:via>soap://B.com</wsrp:via> <wsrp:via>soap://C.com</wsrp:via> </wsrp:fwd> <wsrp:from>soap://A.com/some/endpoint</wsrp:from> <wsrp:id>uuid:84b9f5d0-33fb-4a81-b02b5b760641c1d6</wsrp:id> </wsrp:path> </SOAP-ENV:Header> Specification: http://msdn.microsoft.com/library/default.asp?url=/library/enus/dnglobspec/html/ws-routing.asp 41 WS-Referral 42 WS-Referral is a stateless protocol for inserting, deleting, and querying routing entries in a SOAP router Enables dynamic route configuration Specification released October 2001 by Microsoft While WS-Routing defines a message path ("send message from A to C via B"), WS-Referral enables route configuration – i.e. how does A know about B? 43 A Referral Statement is an XML-based structure that describes a routing entry along with a set of conditions under which the statement is satisfied Each Referral Statement contains 5 parts: A set of SOAP actors for which a statement is intended A set of conditions that have to be met for a statement to be satisfied Descriptive information A statement identifier A set of SOAP routers that a statement is referring to as part of the delegation 44 Some XML Examples Referral Statement: <r:ref xmlns:r="http://schemas.xmlsoap.org/ws/ 2001/10/referral"> <r:for> <r:prefix>soap://b.org</r:prefix> </r:for> <r:if> <r:ttl>43200000</r:ttl> </r:if> <r:go> <r:via>soap://c.org</r:via> </r:go> <r:refId>mid:email@example.com</r:refId> </r:ref> For any SOAP actor starting with the specified prefix, if the referral is less than 12 hours old, then go via "soap://c:org" 45 Dynamic Routing: WS-Referral Referral query/response: <S:Body> <wsr:query> <wsr:for> <wsr:prefix>soap://a.org</wsr:prefix> </wsr:for> </wsr:query> </S:Body> <S:Body> <wsr:queryResponse> <wsr:ref> …referral statement appears here… </wsr:ref> </wsr:queryResponse> </S:Body> Request referral statement for "soap://a.org" Response with referral statement 46 WS-Referral can be useful in multiple cases For example: "DNS-like" services To notify other Web services that a Web service's network address has changed Load balancing A SOAP router is too busy to handle the message – can reroute Message path optimization A "better" path suddenly exists Delegation/message forwarding Specification: http://msdn.microsoft.com/webservices/understanding/gxa/default.aspx?pull =/library/en-us/dnglobspec/html/ws-referral.asp 47 Potential E-Government Applicability May have applicability to E-Government initiatives (such as E-Travel) for load balancing Ex: Can automatically/seamlessly reroute users to another SOAP node when necessary for load balancing purposes 48 WS-Transaction 49 WS-Transaction specifies transactional properties of Web services Specification released August 2002 by Microsoft, IBM and BEA Systems Utilizes 2 Coordination Types: Atomic Transaction Business Activity Atomic Transaction – used to coordinate activities having a short duration and executed within limited trust Has an "all or nothing" property Business Activity – used to coordinate activities that are long in duration and desire to apply business logic to handle business exceptions Actions are applied immediately and are permanent because the long duration prohibits locking data resources 50 A Web services application can include both Atomic Transactions and Business Activities Each Coordination Type can have multiple Coordination Protocols Each is intended to coordinate a different role that a Web service plays in the activity Examples of Coordination Protocols: Completion – a single participant tells the Coordinator to either try to commit the transaction or force a rollback 2PC (2 Phase Commit) – a participant such as a resource manager (ex: database) registers for this, so that the Coordinator can manage a commit/abort decision across all resource managers PhaseZero – Coordinator notifies a participant just before a 2PC protocol begins May need to write cached updates to a database prior to 2PC 51 A "Coordination Service" propagates/coordindates activities between services Messages exchanged between parties carry a Coordination Context Contains information necessary to link the various activities Example of Coordination Context: The CoordinationType "wstx" denotes an Atomic Transaction. The Registration Service will be discussed shortly. <S:Header> <wscoor:CoordinationContext> <wsu:Expires> 2002-06-30T13:20:00.000-05:00 </wsu:Expires> <wsu:Identifier> http://abc.com </wsu:Identifier> <wscoor:CoordinationType> http://schemas.xmlsoap.org/ws/2002/08/wstx </wscoor:CoordinationType> <wscoor:RegistrationService> <wsu:Address> http://xyzregistrationservice.com </wsu:Address> </wscoor:RegistrationService> </wscoor:CoordinationContext> ..... </S:Header> 52 A Coordination Service consists of several components Coordination Service consists of: Activation Service – allows a Coordination Context to be created Registration Service – allows a Web service to register to participate in a Coordination Protocol A set of Coordination Protocol Services for each supported Coordination Type (Completion, 2PC, etc.) 53 Abbreviated Example – Atomic Transaction Process App1 sends a CreateCoordinationContext message to its local Activation Service to create an Atomic Transaction App1 receives a Coordination Context containing the following information: Transaction Identifier Coordination Type Coordinator Port Reference App1 registers with the Coordinator for the "Completion" Coordination Protocol App1 sends a message to App2 containing the Coordination Context 54 Abbreviated Example – Atomic Transaction Process App2 is an application that caches data – it registers with the Coordinator for the "PhaseZero" Coordination Protocol App2 sends a message to App3 containing the Coordination Context App3 is a resource manager – it registers with the Coordinator for the "2PC" Coordination Protocol At this point the Coordinator knows all the participants and what Coordination Protocols they expect to use Specification: http://msdn.microsoft.com/webservices/understanding/gxa/default.aspx?pull =/library/en-us/dnglobspec/html/ws-transaction.asp 55 Potential E-Government Applicability May have applicability to E-Government initiatives (such as Pay.gov) for transactional processing Ex: Ensure that activities (such as payments) are carried out in an atomic ("all-or-nothing") manner 56 Remaining Specifications 57 Remaining Specifications WS-Coordination: Defines Coordination Types used in WS-Transaction Specification: http://msdn.microsoft.com/webservices/understanding/gxa/default.asp x?pull=/library/en-us/dnglobspec/html/ws-coordination.asp WS-Inspection: Defines a Web Services Inspection Language for inspecting a Web site for available services Specification: http://msdn.microsoft.com/library/default.asp?url=/library/enus/dnglobspec/html/ws-inspection.asp 58 Remaining Specifications WS-SecureConversation: Defines mechanisms for establishing security context using session keys, derived keys, and per-message keys Specification: http://msdn.microsoft.com/ws/2002/12/ws-secure-conversation/ DIME (Direct Internet Message Encapsulation): Defines a binary packaging format for SOAP messages with attachments Specification: http://www.ietf.org/internet-drafts/draft-nielsen-dime-02.txt 59 Remaining Specifications WS-Attachments: Defines how DIME packaging can be used to provide the attachment capabilities needed by Web services Specification: http://www.ietf.org/internet-drafts/draft-nielsen-dime-soap-01.txt WS-Privacy (Pending) WS-Federation (Pending) WS-Authorization (Pending) 60 Conclusions The Global XML Web Services Architecture is poised to play a major role in advancing the adoption of Web services through its robust specification of mechanisms for Web services such as security, policy, coordination, federation, and routing. Several GXA specifications (WS-Transaction, WSCoordination) appear to be plausible likely candidates for inclusion in W3C's upcoming Web Services Choreography Language Specification. 61 QUESTIONS? 62 Contact Information Joseph M.

With an intriguing premise, which enabled the author to walk the length of the Pennines without ever getting his feet wet, this book sets out to follow Britain's watershed. As Andrew Bibby explains in The Backbone of England (Frances Lincoln, 20), this is the high point that divides water that will flow west, into the Irish Sea, from that trickling east, towards the North Sea: a course not influenced, by man-made roads or boundaries. With photography, by John Morrison, which brings out the unique, slaty beauty of this particular landscape, Bibby is keen to point out how the activities of man here do impact on the area and the world's climate. The carbon-setting properties of peat, the right to roam and the politics of killing crows all come into it.

I have two networks running Sp1.5 both use the same
email address to make routing of reports and alerts
centralized. One net is in Chicago the other in Scottsdale.
I recieved a "Weekly Spiceworks Report" from chicago
6/4 and scottsdale 6/11. Is there a setting somewhere
for these summary reports to be turned on or off? Ever since I turned on the scottsdale net I receive no Weekly Summary Report for chicago or are these reports only
generated when there are changes?

Release 1.6 added the ability to change the time that these reports go out. Each Spiceworks user who has the 'receive notifications' check box checked should get the email. If you don't want the email, you can uncheck this box.

From an afternoon press conference to the opening night festivities, the actor basically stole the show with high-fives, laughter and even a little dancing at the top of the steps outside the Palais. When this year's Cannes jury roster was announced, there was really only one head scratcher in the bunch: Will Smith.
At first glance, the actor might've seemed an odd choice to serve under president Pedro Almodovar for the 70th annual event, considering that none of the 40 films he's made in his career have screened at Cannes, the most prestigious, and perhaps most discerning, film festival in the world.
But Smith, 48, who for years ranked as the biggest box-office star in the business, silenced snarky film snobs on Wednesday in the most fun way possible: Killing 'em with charisma.
He clearly didn't forget to pack his movie star charm, showing up to a series of events to kick off the film festival and winning over press, cinephiles and adoring fans everywhere he went.
Nobody is having more fun on #Cannes70 opening night than @willsmith who is loving fans, saying hi to security, posing for pics. #Cannes2017 pic.twitter.com/wMCMCGhcZv

One might dare to say that Smith even stole the show on opening night at the Palais where the festival opened with Arnaud Desplechin's Ismael's Ghosts.
After getting out of his car, Smith was seen posing for photos with fans against the barricades on the Croisette, high-fiving others, and saying hello to security guards in the street before making his red-carpet debut to join his fellow jury members for a group photo.

HALF-BAKED warnings on the dangers of eating bread don't have a grain of
truth, a study shows.
Consumption has fallen after two decades of claims that bread causes bloating,
sparks weight gain — and that wheat allergies are on the rise.
But most of the alerts are just myths, experts say. And people are missing out
on vital vitamins and minerals by removing it from their daily diet.
Furthermore, despite now eating less bread than any other European country,
our nation has the biggest obesity problem, doctors said.
The research was carried out by nutrition scientist Dr Aine O'Connor, based at
the British Nutrition Foundation in central London.
It found standard sliced white bread had been unfairly "demonised" by health
campaigners and TV nutritionists.
Dr O'Connor found genuine wheat allergies were not up, only the number of
people who incorrectly diagnosed one themselves.
She said: "Health professionals need to dispel the myths. Bread is an
important source of nutrition."
By ALEX JAMES, Sun Food Columnist
BREAD is a terrible thing to have to deny yourself.
Bread and butter is so simple but so good — and who can resist hot buttered
In France they buy a fresh baguette every day, and the French have the lowest
obesity rate in Europe.
That's because the French eat sensibly and spend money on buying good food and
good ingredients — quality over quantity.
Bread isn't completely blameless though, and swapping from white to wholemeal
is a good idea. Wholemeal will make you feel fuller for longer.
