A surgical stapling apparatus includes a staple cartridge and an anvil member. The staple cartridge includes a plurality of surgical fasteners disposed in rows of retention slots. The staple cartridge may have an annular or linear configuration of retention slots. The tissue contacting surface of the staple cartridge may be tapered or stepped. The anvil member has a tissue contacting surface that includes a number of pockets arranged for substantially aligning with the retention slots. In addition, the tissue contacting surface of the anvil member may complement the tissue contacting surface of the staple cartridge.

The invention is directed to a surgical instrument comprising an elongate tube extending along an axis including a camming rod and an actuation mechanism operably connected to the camming rod, the camming rod having a camming pin and a camming projection; a first jaw spine having a first cam slot, a first interior camming surface, and a first exterior camming surface; and a second jaw spine having a second cam slot, a second interior camming surface, and a second exterior camming surface, the second jaw spine pivotally connected to the first jaw spine at a common pivot pin operably connected to the elongate tube to open and close the jaw spines in response to movement of the actuation mechanism. The camming pin rides along the first and second interior camming surfaces and operates to close the jaw spines when the camming rod is moved proximally. When the camming rod moves distally, the camming projection rides on the first and second exterior camming surfaces formed on the proximal sides of the respective first and second jaw spines and operates to open the jaw spines. A feature of the invention is one camming surface on each jaw spine can facilitate closing the jaw spines while the other camming surface on each jaw spine can facilitate opening the jaw spines. These two camming surfaces on each jaw spine can be widely separated. The jaw spines can be formed of a metallic material and are overmolded with an atraumatic plastic material. By overmolding the plastic onto the metal spine, an atraumatic outer surface can be formed of the plastic material along with a high degree of detail.

Soft, durable and bulky tissue products comprising non-wood fibers and more particularly high yield hesperaloe pulp fibers are disclosed. The tissue products preferably comprise at least about 5 percent, by weight of the product, high yield hesperaloe pulp fiber and have relatively modest tensile strengths, such as a geometric mean tensile (GMT) less than about 1,000 g / 3″, and improved durability and cross-machine direction (CD) properties, such as a CD Stretch greater than about 10 percent. Additionally, at the foregoing tensile strengths the products are not overly stiff. For example the tissue products may have a Stiffness Index less than about 10.0.

An efficient, low-loss, low sidelobe, high dynamic range phased-array radar antenna system is disclosed that uses metamaterials, which are manmade composite materials having a negative index of refraction, to create a biconcave lens architecture (instead of the aforementioned biconvex lens) for focusing the microwaves transmitted by the antenna. Accordingly, the sidelobes of the antenna are reduced. Attenuation across microstrip transmission lines may be reduced by using low loss transmission lines that are suspended above a ground plane a predetermined distance in a way such they are not in contact with a solid substrate. By suspending the microstrip transmission lines in this manner, dielectric signal loss is reduced significantly, thus resulting in a less-attenuated signal at its destination.

A method wherein lignocellulosic biomass materials are converted into combustible fuel products. In particular, the method is a continuous process, involving wet oxidation or steam explosion, for fermentatively converting such biomass materials into ethanol using a process design that permits all or part of the process water from the ethanol fermentation process to be recycled to reduce the consumption of process water. The effluent from the ethanol fermentation step may be subjected to an anaerobic fermentation step generating methane and a water effluent in which the amount of potentially inhibitory substances is at a sub-inhibitory level, which in turn permits all or part of the effluent water from the anaerobic fermentation step to be recycled into the process.

A construction of thin strain-relaxed SiGe layers and method for fabricating the same is provided. The construction includes a semiconductor substrate, a SiGe buffer layer formed on the semiconductor substrate, a Si(C) layer formed on the SiGe buffer layer, and an relaxed SiGe epitaxial layer formed on the Si(C) layer. The Si(C) layer is employed to change the strain-relaxed mechanism of the relaxed SiGe epitaxial layer formed on the Si(C) layer. Therefore, a thin relaxed SiGe epitaxial layer with low threading dislocation density, smooth surface is available. The fabricating time for fabricating the strain-relaxed SiGe layers is greatly reduced and the surface roughness is also improved.

The invention relates to a light source comprising a light-emitting element, which emits light in a first spectral region, and comprising a luminophore, which comes from the group of alkaline-earth orthosilicates and which absorbs a portion of the light emitted by the light source and emits light in another spectral region. According to the invention, the luminophore is an alkaline-earth orthosilicate, which is activated with bivalent europium and whose composition consists of: (2-x-y)SrOx(Ba, Ca)O(1-a-b-c-d)SiO2aP2O5bAl2O3cB2O3dGeO2:yEu<2+> and / or (2-x-y)BaOx((Sr, Ca)O(1-a-b-c-d)SiO2aP2O5bAl2O3cB2O3dGeO2:yEu<2+>. The desired color (color temperature) can be easily adjusted by using a luminophore of the aforementioned type. The light source can contain an additional luminophore selected from the group of alkaline-earth aluminates, activated with bivalent europium and / or manganese, and / or can contain an additional red-emitting luminophore selected from the group Y(V, P, Si)O4:Eu or can contain alkaline-earth magnesium disilicate.
