摘要:
A portable basketball goal support system having a base, a ballast tank, and an arm for supporting a basketball goal support pole can be assembled in a compact configuration for shipping or storage and an expanded configuration for use. The support pole is mounted at a rear portion of the base and angled forward in the expanded configuration. In the expanded configuration, the ballast tank extends at least partially behind the support pole, while in the compact configuration, the ballast tank may be nested within portion of the base, thereby occupying less space. The support pole may be formed with a generally "pear"-shaped cross section defined by large and small curved portions connected by relatively straight sections, such that the large curved portion readily adapts to existing mounting hardware. One or more of the base, ballast tank, and support arm may be formed from plastic with a printed graphics sheet integrally molded therewith.
摘要:
A method of packing a portable basketball goal support system having a base, a ballast tank, and an arm for supporting a basketball goal support pole which can be assembled in an expanded configuration for use and a compact configuration for shipping or storage. In the expanded configuration, the ballast tank extends at least partially behind the support pole providing stability for the base, while in the compact configuration, the ballast tank may be nested within a portion of the base, thereby occupying less space. The overall length, height, and thickness of the support assembly are thus reduced for storage, thus occupying less space when shipped or stored than would be possible in previous conventional designs providing comparable performance.

Zeolite SSZ-33 containing titanium in its framework is prepared by post-synthesis treatment with titanium tetrachloride. The titanium-containing SSZ-33 is useful as a catalyst in oxidation reactions.
摘要:
Supported phase catalysts in which the support phase, is non-aqueous and highly polar, such as a primary alcohol, and most preferably ethylene glycol, are. disclosed. An organometallic compound, preferably a metal complex of chiral sulfonated 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl is dissolved in the ethylene glycol. Such supported phase catalysts are useful for asymmetric synthesis of optically active compounds, such as the preparation of dehydronaproxen.

A method and recording for use in achieving Alpha and Theta brain wave states and effecting positive emotional states in humans to enhance learning and self-improvement, is provided which includes a medium having a musical composition recorded thereon with an initial tempo decreasing to a final tempo and verbal phrases, comprising between approximately 4 and approximately 8 words, recorded in synchrony with the decreasing initial tempo.
摘要:
A substantially nitrate-free solution for milling products of refractory metals, especially titanium, which milling solution comprises: (a) about 20-100 g/l hydrofluoric acid; (b) a hydrogen inhibitor selected from the group comprising of: about 55-650 g/l of sodium chlorate, about 180-650 g/l of ammonium peroxysulfate, and at least about 10 g/l of hydrogen peroxide; and (c) a balance of water and impurities. A method for chemically milling, etching and/or pickling metal products, such as titanium alloy forgings, with the aforementioned solution is also disclosed.
摘要:
A process for the hydroformylation of alkenes and other olefinically unsaturated reactants by reaction with carbon monoxide and hydrogen in the presence of a heterogeneous catalyst comprising a solid surface having immobilized thereon a solution of one or more rhodium complexes which is essentially immiscible with the organic reactant. Catalyst is subsequently recovered from the resulting hydroformylation product by one or more solid-liquid separation techniques.
摘要:
The present invention relates to novel compositions of therapeutic cyclodextrin containing polymeric compounds designed as a carrier for small molecule therapeutics delivery and pharmaceutical compositions thereof. These cyclodextrin-containing polymers improve drug stability and solubility, and reduce toxicity of the small molecule therapeutic when used in vivo. Furthermore, by selecting from a variety of linker groups and targeting ligands the polymers present methods for controlled delivery of the therapeutic agents. The invention also relates to methods of treating subjects with the therapeutic compositions described herein. The invention further relates to methods for conducting pharmaceutical business comprising manufacturing, licensing, or distributing kits containing or relating to the polymeric compounds described herein.
摘要:
Micro-cavity resonant sensors have outer surfaces that are functionalized using click chemistry, e.g., involving a cycloaddition reaction of an alkyne functional group and an azide functional group. A first polymer linking element binds to an outer surface of the micro-cavity and has an azide functional group, which bonds to an alkyne functional group of a second polymer linking element as a result of a cycloaddition reaction. A functionalization element such as an antibody, antigen or protein for sensing a target molecule is bound to the second linking element.
摘要:
The invention provides a composition containing particulate composite of a polymer and a therapeutic agent. The composition also contains a complexing agent. The polymer interacts with the complexing agent in a host-guest or a guest-host interaction to form an inclusion complex. Both the polymer of the particulate composite and the complexing agent may be used to introduce functionality into the therapeutic composition. A therapeutic composition of the invention may be used to deliver the therapeutic agent and to treat various disorders. The invention also relates to a method of preparing a composition of the present disclosure. The invention further relates to a method of delivering a therapeutic agent, using the composition of the present disclosure, where a therapeutically effective amount of a therapeutic composition of the invention may be administered to a mammal (e.g. person or animal) in recognized need of the therapeutic.
