Z-2 Architecture Description and Requirements Verification Results
(46th International Conference on Environmental Systems, 2016-07-10)The Z-2 Prototype Planetary Extravehicular Space Suit Assembly is a continuation of NASA’s Z series of spacesuits. The Z-2 is another step in NASA’s technology development roadmap leading to human exploration of the Martian ... -
Z-2 Prototype Space Suit Development
(44th International Conference on Environmental Systems, 2014-07-13)NASA’s Z-2 prototype space suit is the highest fidelity pressure garment from both hardware and systems design perspectives since the Space Shuttle Extravehicular Mobility Unit (EMU) was developed in the late 1970’s. Upon ... -
Z-2 Space Suit: A Case Study in Human Spaceflight Public Outreach
(46th International Conference on Environmental Systems, 2016-07-10)NASA Johnson Space Center’s Z-series of planetary space suit prototypes is an iterative development platform with a Mars-forward design philosophy, targeting a Mars surface mission in the mid-2030s. The first space suit ... -
Z-2 Threaded Insert Design and Testing
(46th International Conference on Environmental Systems, 2016-07-10)NASA’s Z-2 prototype space suit contains several components fabricated from an advanced hybrid composite laminate consisting of IM10 carbon fiber and fiber glass. One requirement was to have removable, replaceable helicoil ... -

The Zen of Ionesco: A production
(2001-12)In my mind's eye, there are many facets to the Texas Tech production of Victims of Duty which lend themselves to in-depth study and explanation. My goal in this thesis is to focus on only one such facet- a thread which ... -
Zeolite Degradation: An Investigation of CO2 Capacity Loss of 13x Sorbent
(47th International Conference on Environmental Systems, 2017-07-16)System testing of the Carbon Dioxide Removal and Compression System (CRCS) has revealed that sufficient CO2 removal capability was not achieved with the designed system. Subsystem component analysis of the zeolite bed ... -
The Zero Gravity Mass Measurement Device
(45th International Conference on Environmental Systems, 2015-07-12)The Zero Gravity Mass Measurement Device (ZGMMD) provides the ability to quantify the mass of objects, including live animal specimens, in a microgravity environment. There are currently no mass measurement devices available ... -
Zero voltage switching resonant converter using 0.6μm technology
(2016-05)There has been a rapid advancement in the technology for the development of high performance DC-DC converters. Resonant switching buck converter is one such power conversion topology and is designed to achieve maximum ... -
Zero-cost sustainable design for residential building: A study in energy-efficient design for residential properties
(2008-12)Through the use of passive energy design, combined with efficient technologies, it is possible to design a home that will have a lesser impact on the environment, and use less energy than a typical home without increasing ... -
Zero-norm optimization: Models and applications
(2010-12)A zero-norm optimization model is a mathematical program in which one either minimizes or restricts the number of certain sets of variables to being non-zero. Zero-norm optimization arises in various applications, such as ... -

Zilker Zoological Park: a zoo for Central Texas, Austin, Texas
(Texas Tech University, 1990-05)The creation of uncandid architecture, architecture that at first glance appears simple in form and in design, but with further investigation becomes more complex and complicated and bridges the dichotomous relationship ... -
Zilpaterol Hydrochloride affects Cellular Muscle Metabolism and Lipid Components of 10 Different Muscles in Feedlot Heifers
(2017)This study determined if zilpaterol hydrochloride (ZH) altered muscle metabolism and lipid components of 10 muscles. Crossbred heifers were either supplemented with ZH (n = 9) or not (Control; n = 10). Muscle tissue was ... -
Zilpaterol hydrochloride alters abundance of β-adrenergic receptors in bovine muscle cells but has little effect on de novo fatty acid biosynthesis in bovine subcutaneous adipose tissue explants
(2012)We predicted that zilpaterol hydrochloride (ZH), a β-adrenergic receptor (AR) agonist, would depress mRNA and protein abundance of β-AR in bovine satellite cells. We also predicted that ZH would decrease total lipid synthesis ...
