 Home restaurant busted in Freehold
Jeffrey Palatini, who is the principal registered environmental health specialist with the Freehold Area Health Department, said that although Hernandes and Borst were both given notices of violation on Aug. 30, a second summons was served by Palatini on Sept. 15 to Hernandes, which was received by her sister, Rosabla.
Palatini said he had observed the exterior of the property in the beginning of September and did not see any evidence to indicate that the home was again being used as a restaurant.
Palatini said he told Borst his responsibility did not end with those actions, but that as the owner of the home he would still be responsible to monitor the property.

  The physics of isolated horizons
The crucial point of the definition is that it is possible to add a surface term to the usual bulk action of general relativity, possibly coupled with suitable matter fields like Maxwell and scalar fields such that the action is differentiable within the corresponding class of spacetimes.
This is analogous to the usual addition of a surface term to the bulk action of general relativity on manifolds with boundary formulated in terms of the spacetime metric in such a way that it becomes differentiable on the class of spacetimes with a fixed value of the metric on the manifold boundary.
The fact that such a differentiable action exists seems to depend completely on the choice of the physical boundary conditions and not so much on the choice of variables, as long as the action is a first order action as in the Palatini formulation.

Zoom Broom, Margie Palatini's over-the-top sequel to the immensely popular Piggie Pie, is as smart-alecky and fast-paced as they come, and Howard Fine's colorful, action-packed, almost grotesquely intense illustrations are perfect for this wild and witchy ride.
Palatini loads the story with off-hand references to such witchy standbys as "Hansel and Gretel," The Wizard of Oz and the TV series Bewitched and pokes fun at the stereotypically sleazy salesguy.

 Anatomy of the Swallow
The palatoglossal and the levator veli palatini both raise the velum.
The latest research on swallowing suggests that the action of the pharyngeal constrictor muscles is not the most critical factor in the movement of food down the pharynx.
This action also aids in the relaxation and opening of the cricopharyngeus muscle.

Opening the eustachian tube occurs by coordinating action of the two palatal muscles (levator and tensor palatini).
The normal action that opens the eustachian tube and causes this are swallowing and yawning.
Some patients are bothered by the clicking sound in the ear which accompanies the action of swallowing and some patients can produce these sounds voluntarily and elicit this type of noise.

 2.3 The Chern-Simons formulation
The formalism of geometric structures provides an elegant description of vacuum spacetimes in 2+1 dimensions, but it is rather remote from the usual physicist’s approach.
In particular, the Einstein-Hilbert action is nowhere in sight, and even the metric makes only a limited appearance.
The first-order action allows us an additional step that was unavailable in the geometric structure formalism - we can compute the symplectic structure on the space of solutions.

 eMedicine - Snoring and Obstructive Sleep Apnea, Physiologic Approach : Article by John M Truelson, MD, FACS
The levator palatini muscles originate at the apex of the petrous bone and the cartilaginous portion of the eustachian tubes and extend obliquely into the posterior superior palate, where they blend at the midline into the palatal aponeurosis.
If the tensor palatini muscles are relaxed during the contraction of levator palatini muscles, 2 dimples appear on the oral surface of the palate.
The tensor veli palatini arises from the pterygoid plate, the sphenoid bone, and the cartilaginous eustachian tube and extends downward, passes under the hamulus, then passes medially and inserts into the palatal aponeurosis.

 Einstein-Hilbert action - Wikipedia, the free encyclopedia
The Einstein-Hilbert action is a mathematical object (an action) that is used to derive Einstein's field equations of general relativity.
In general relativity, the action is assumed to be a functional only of the metric, i.e.
Some extensions of general relativity assume the metric and connection to be independent, however, and vary with respect to both independently.

The action for the theory then becomes the Chern-Simons action, as noted by Witten.
The classic action principle for general relativity is the Einstein-Hilbert action: the Ricci scalar times the volume form associated to the metric.
More recently, Plebanski invented an action using the self-dual part of the connection and a tetrad field; this turns out to be closely related to an action naturally associated with the Ashtekar "new variables" (a self-dual connection and tetrad field), although this was realized only subsequently by Capovilla, Dell, and Jacobson.

 Pharmacy Pearl 29 September 2004
C. In 8 healthy volunteers (Palatini et al, 1993) and in 10 alcoholic patients treated with oral sodium oxybate 25 mg/kg, renal excretion was less than 1% (Ferrara et al, 1992).
In an animal model of myoclonus induced by intraperitoneal injection of the GABA-agonist muscimol, the effect was reduced by sodium oxybate in a manner similar to baclofen (Menon, 1981).
Sodium oxybate may produce anesthesia by a general suppressant action on the entire cerebrospinal axis, and muscular relaxation by an action on the spinal cord rather than a direct action on the neuromuscular junction (Doherty et al, 1975).

(1) During swallowing, the lumen of the eustachian tube opens, and the toms tubarius elevates as a result of the combined action of three muscles: the tensor veil palatini, the levator veli palatini, and the superior constrictor.
(2) The tensor veli palatini is the most functionally significant muscle that actively opens the eustachian tube.
The eustachian tube has at least three physiologic functions with respect to the middle ear: (1) it provides ventilation, (2) it protects against nasopharyngeal sound pressure and secretions, and (3) it drains and clears middle ear secretions.

 Trigeminal Pharyngioplasty
Dysfunction of the tensor palatini and tensor tympani muscles can be due to referred pain from facial, neck, shoulder, pectoralis, soleus, and even metatarsal muscles, causing secondary myofascial pain in these two forgotten accessory muscles of mastication, causing trigger points and shortening of these muscles (83-85).
A functional tensor veli palatini muscle causes the torus tubarius to be soft and fleshy, while a dysfunctional tensor veli palatini muscle causes the torus tubarius to be hard and seemingly unpliable.
The treatment of these accessory muscles of mastication, the tensor veli palatini and tensor tympani muscles, has shown to improve orofacial, temporomandibular joint, cervical, and shoulder pain complaints; and has also shown to be associated with the relief of ear pain, ear pressure, tinnitus, vertigo, and/or hearing impairment or hearing loss.

Caesar, during his conquest of Gaul, was given many opportunities of seeing the Gallic horsemen in action and it is hardly surprising that he was soon recruiting them, taking a large contingent with him to fight against Pompey.
The numbers of the new troops he originally raised, the palatini, are not known.
But by the end of the fourth century this new imperial guard mustered twenty four vexillations of cavalry (five hundred each), twenty-five legions (a thousand each) and one hundred and eight auxiliary troops (five hundred each), stationed all around the empire at the major cities.

This is called the "Palatini" action - and actually I'm going to describe a slight variation on it, that is conceptually simpler, and apparently appears for the first time in Ashtekar's book.
In the Palatini approach one thinks of general relativity not as being a theory of a metric, but of a "tetrad" and an "so(3,1) connection".
So the Palatini trick is to rewrite the Einstein-Hilbert action in terms of the curvature of the so(1,3) connection and the tetrad field.

We consider the Palatini formalism of gravity with cosmological constant Λ coupled to a scalar field φ in n-dimensions.
It turns out that both Palatini action and Hilbert action lead to the same geometric dynamics in the presence of Λ and φ.
While, the n-dimensional Palatini action could not give a connection dynamics formalism directly.

We consider theories of gravity where the Lagrangian is a nonlinear function of the Ricci scalar, in the Palatini variational formalism where the connection and metric are independent.
We show that such theories are equivalent to scalar-tensor theories in which the scalar field kinetic energy term is absent from the action.
By integrating out the scalar field, the theory can be recast as general relativity coupled to a modified matter action.

 Generalization of the Hilbert-Palatini Action in Four-Dimensional Gravity
The generalized two-parametric Hilbert-Palatini action is constructed, which not only includes the well-known Hilbert-Palatini and Ashtekar gravitational theory as special cases, but also gives new results.
In Hamiltonian formulation, the phase space variables and the corresponding Hamiltonian constraints can be obtained, including the Ashtekar and Barbero type constraints.
Moreover, the results of this action are the same as those given by the parametric canonical transformations, although these two methods are completely different.
