Direct‐Seeding Techniques for Guayule Stand Establishment in West Texas (1992)

A major limiting factor in the commercialization of guayule ( Parthenium argentatum Gray) is the high cost of stand establishment. Presently, guayule stands must be established by transplanting seedlings from a greenhouse. Production costs could be lowered considerably by the development of direct seeding techniques. The objective of this study was to examine the effects of seed conditioning, planting depth, and mulch on guayule stand establishment by direct seeding in west Texas. Experiments were initiated on a Delnorte very gravelly loam (loamy‐skeletal, mixed, thermic Typic Paleorthids) during July, August, September, and October of 1988 and 1989 at the Texas Agricultural Experiment Station Guayule Research Site near Ft. Stockton. Conditioned and raw seed were planted on raised beds at 25 seeds/ft, with a Gaspardo (Gaspardo, Tagiamento, Pordenone, Italy) SV255 pneumatic planter. Planting depths and methods included: (i) 0.4 in. deep followed by the planter presswheel, (ii) 0.4 in. deep followed by the presswheel and drag chain, and (iii) on the soil surface. Coarse vermiculite and bare soil comprised mulch treatments. The plots were sprinkler irrigated and kept moist during germination and emergence. The greatest amount of water (52–100%) was applied during the first 30 d after planting. Seedling density was greatest when conditioned seed was planted 0.4 in. deep. Vermiculite mulch was beneficial only with surface planting when rainfall occurred immediately after planting. Successful seeding in west Texas required planting conditioned seed at least 0.4 in. deep during late spring and summer.
Vortex Induced Flutter in Compliant Plate Seals (2012)

This paper investigates the possibility of vortex induced flutter in GE compliant plate seals (CPS). The CPS consists of a ring of slotted compliant plates attached circumferentially around the rotor, with an intermediate plate seated in the slot. Experiments show that the compliant plates vibrate in the flow field with amplitude that is a function of the differential pressure applied across the seal. The vibrations are caused by potentially multiple flow induced vibration mechanisms operating during different flow regimes. This work focuses on the dynamic instabilities that may be caused by the vortices shed by individual compliant plates and the intermediate plate. We model the compliant plate seal as a ring of a large number of locally coupled oscillators, with nonlinear stiffness arising from hydrostatic feedback. A two-way coupling exists between the structural and wake dynamics, leading to the phenomenon of “lock-in” between the wake and successive modes of seal vibration as the flow velocity is increased. Using eigenvalue analysis, we obtain the transition boundaries that divide the parameter space into sets of regions with positive and negative damping, corresponding to boundaries of onset and end of vortex induced flutter. Based on averaged equations, the amplitude of the limit cycles of the structure and wake dynamics and the phase between them is determined. It is found that the nonlinearities in seal stiffness and the nature of coupling between the compliant plates have a significant effect on the stability boundaries.

Comparison of the galactopoietic response to pituitary-derived and recombinant-derived variants of bovine growth hormone (1992)

Two studies were designed to examine the differences in galactopoietic potency of molecular variants of pituitary- and recombinant-derived bovine GH (bGH). The recombinant bGH molecules included amino-terminal and position-127 amino acid substitutions which are representative of two of the four natural pituitary variants or of partially degraded bGH molecules. Amino-terminal variants of bGH included methionine (Met1), alanine (Ala1), serine (Ser1) or deletion of four amino acids (delta 1-4). The delta 1-4 variants were representative of degradation products previously isolated in pituitary bGH preparations. In the first study, 54 lactating Holstein cows received i.m. injections of a buffer solution (control), pituitary-derived bGH, or recombinant-derived [Met1,Leu127]-bGH, [Met1,Val127]-bGH, [Ala1,Leu127]-bGH, or [Ala1,Val127]-bGH. Cows received 25 mg bGH/day for 21 days. Substitution of the amino-terminal alanyl residue with methionine did not affect milk response. GH variants with Val127 elicited a greater milk response (8.5 kg/day) than Leu127 bGH variants (6.5 kg/day). The average milk response to the four recombinant bGH variants was 7.5 kg/day greater than controls compared with 4.4 kg/day for pituitary-derived bGH. In contrast, blood bGH concentrations were equivalent for pituitary and recombinant bGH treatments, approximately 20 micrograms/l more than control levels at 3 h after injection. Blood free fatty acid concentrations were increased, but insulin and glucose levels were unaffected by bGH treatment. In the second study, 54 lactating Holstein cows received i.m. injections of a buffer control solution or recombinant-derived [Met1,Leu127]-bGH, [Ser1,Leu127]-bGH, [Ser1,Val127]-bGH, [delta 1-4,Leu127]-bGH or [delta 1-4,Val127]-bGH. Cows received 25 mg bGH/day for 28 days. The milk response to full-length bGH variants was 6.6 kg/day greater than the response to the amino-terminal deletion variants (P less than 0.05). Substitution of valine for leucine did not affect milk response to either the deletion (delta 1-4) or full-length (Met1 or Ser1) bGH molecules. In conclusion, the lowered galactopoietic potency of pituitary bGH preparations was demonstrated, at least in part, to be due to the presence of amino-terminal amino acid deletions rather than differences in amino acid sequences of recombinant bGH. Ala1 bGH variants with valine at position 127 elicited a greater milk response than Leu127 variants.
Biodegradability of Polyethylene terephthalate Copolymers with Polyethylene glycols and Polytetramethylene glycol (1996)

Poly(ethylene terephthalate) copolymers were prepared by melt polycondensation of dimethyl terephthalate and excess ethylene glycol with 10–40mol% (in feed) of poly(ethylene glycol) (E) and poly(tetramethylene glycol) (B), with molecular weight (MW) of E and B 200–7500 and 1000, respectively. The reduced specific viscosity of copolymers increased with increasing MW and content of polyglycol comonomer. The temperature of melting (Tm), cold crystallization and glass transition (Tg) decreased with the copolymerization. Tm depression of copolymers suggested that the E series copolymers are the block type at higher content of the comonomer. Tg was decreased below room temperature by the copolymerization, which affected the crystallinity and the density of copolymer films. Water absorption increased with increasing content of comonomer, and the increase was much higher for E1000 series films than B1000 series films. The biodegradability was estimated by weight loss of copolymer films in buffer solution with and without a lipase at 37°C. The weight loss was enhanced a little by the presence of a lipase, and increased abruptly at higher comonomer content, which was correlated to the water absorption and the concentration of ester linkages between PET and PEG segments. The weight loss of B series films was much lower than that of E series films. The abrupt increase of the weight loss by alkaline hydrolysis is almost consistent with that by biodegradation.
Agrin Can Mediate Acetylcholine Receptor Gene Expression in Muscle by Aggregation of Muscle-derived Neuregulins (1998)

The neural isoforms of agrin can stimulate transcription of the acetylcholine receptor (AChR) epsilon subunit gene in electrically active muscle fibers, as does the motor neuron upon the formation of a neuromuscular junction. It is not clear, however, whether this induction involves neuregulins (NRGs), which stimulate AChR subunit gene transcription in vitro by activating ErbB receptors. In this study, we show that agrin- induced induction of AChR epsilon subunit gene transcription is inhibited in cultured myotubes overexpressing an inactive mutant of the ErbB2 receptor, demonstrating involvement of the NRG/ErbB pathway in agrin- induced AChR expression. Furthermore, salt extracts from the surface of cultured myotubes induce tyrosine phosphorylation of ErbB2 receptors, indicating that muscle cells express biological NRG-like activity on their surface. We further demonstrate by RT-PCR analysis that muscle NRGs have Ig-like domains required for their immobilization at heparan sulfate proteoglycans (HSPGs) of the extracellular matrix. In extrasynaptic regions of innervated muscle fibers in vivo, ectopically expressed neural agrin induces the colocalized accumulation of AChRs, muscle-derived NRGs, and HSPGs. By using overlay and radioligand-binding assays we show that the Ig domain of NRGs bind to the HSPGs agrin and perlecan. These findings show that neural agrin can induce AChR subunit gene transcription by aggregating muscle HSPGs on the muscle fiber surface that then serve as a local sink for focal binding of muscle-derived NRGs to regulate AChR gene expression at the neuromuscular junction.

A 1-Gb/s/pin 512-Mb DDRII SDRAM using a digital DLL and a slew-rate-controlled output buffer (2002)

We developed a 1-Gb/s/pin 512-Mb DDRII SDRAM composed of a digital delay-locked loop (DLL) and a slew-rate controlled output buffer. The digital DLL has a frequency divider for the DLL input, which performs at a operating frequency of up to 500 MHz at 1.6 V, and it provides internal clocking with 50% duty-cycle correction. The DLL has a current-mirror-type interpolator, which enables a resolution as high as 14 ps, is standby-current-free, and can operate at voltages as low as 0.8 V. The slew-rate impedance-controlled output buffer circuit reduces the output skew from 107 to 10 ps. This SDRAM was tested using a 0.13-/spl mu/m 126.5 mm/sup 2/ 512 Mb device.
On the Crushing Mechanics of Thin-Walled Structures (1983)

A self-consistent theory is presented which describes the crushing behavior of a class of thin-walled structures. Assuming a rigid-plastic material and using the condition of kinematic continuity on the boundaries between rigid and deformable zones, a basic folding mechanism is constructed. This mechanism closely reproduces all the main features of folds and wrinkles actually observed on typical crumpled sheet metal structures. Calculations based on the energy balance postulate show that two-thirds of the plastic energy is always dissipated through inextensional deformations at stationary and moving plastic hinge lines. The extensional deformations are confined to relatively small sections of the shell surface but they account for the remaining one-third of the dissipated energy. The theory is illustrated by application to the problem of progressive folding of thin-walled rectangular columns. A good correlation is obtained with existing experimental data as far as the mean crushing force and the geometry of the local collapse mode is concerned.
Performance Evaluation Process of the Content Management System: Case Study of Kau Marz System (2012)

Abstract: The selection and implementation process of a content management system (CMS) represents one of the largest information technology (IT) projects tackled by many organizations specially the academic institutions that have a huge volume of data needed to be managed well. A content management system can be defined as software that is used to support the creating, updating, publishing, translating archiving and retiring of digital information. A traditional software evaluation process involves approximately seven steps: requirements gathering, literature and industry research review, candidate selection and request for proposal, vendor demonstration, formal evaluation and software selection. Evaluating content management systems can be an overwhelming task because there are tons of them to choose from. However, with a structured approach to our evaluation, things can be much easier and less intimidating. So, the goal of the evaluation process is to determine which software can be used to support which website goals. The main interest of this paper is to use some trend data from research organizations to form evaluation criteria that can be used for analyzing the performance of the CMS that is developed in King Abdul-Aziz University (KAU) named MARZ. Also, we check whether these criteria are sufficient and adopted for evaluation process or need further enhancement and modifications. Key words: IT CMS WCM KAU SSMM MARZ RLO ECM HTML FTP and DAM
Native Chemical Ligation at Glutamine (2012)

The desulfurization reaction introduced by Yan and Dawson as a postnative chemical ligation step greatly expanded the scope of ligation chemistry beyond Xaa-Cys (Xaa is any amino acid) by making ligation at Xaa-Phe, Xaa-Val, Xaa-Lys, Xaa-Leu, Xaa-Thr, and Xaa-Pro junctions accessible in the synthesis of functional proteins. A new ligation site based on Xaa-Gln utilizing γ-mercaptoglutamine is reported, and several examples on the efficiency of ligation coupled with desulfurization are provided.
ABL kinases promote breast cancer osteolytic metastasis by modulating tumor-bone interactions through TAZ and STAT5 signaling (2016)

Bone metastases occur in up to 70% of advanced breast cancer. For most patients with breast cancer, bone metastases are predominantly osteolytic. Interactions between tumor cells and stromal cells in the bone microenvironment drive osteolytic bone metastasis, a process that requires the activation of osteoclasts, cells that break down bone. We report that ABL kinases promoted metastasis of breast cancer cells to bone by regulating the crosstalk between tumor cells and the bone microenvironment. ABL kinases protected tumor cells from apoptosis induced by TRAIL (TNF-related apoptosis-inducing ligand), activated the transcription factor STAT5, and promoted osteolysis through the STAT5-dependent expression of genes encoding the osteoclast-activating factors interleukin-6 (IL-6) and matrix metalloproteinase 1 (MMP1). Furthermore, in breast cancer cells, ABL kinases increased the abundance of the Hippo pathway mediator TAZ and the expression of TAZ-dependent target genes that promote bone metastasis. Knockdown of ABL kinases or treatment with ABL-specific allosteric inhibitor impaired osteolytic metastasis of breast cancer cells in mice. These findings revealed a role for ABL kinases in regulating tumor-bone interactions and provide a rationale for using ABL-specific inhibitors to limit breast cancer metastasis to bone.

Serotonin via 5‐HT<sub>7</sub> receptors activates p38 mitogen‐activated protein kinase and protein kinase C ɛ resulting in interleukin‐6 synthesis in human U373 MG astrocytoma cells (2005)

Serotonin [5-hydroxytryptamine (5-HT)] is a widely distributed neurotransmitter which is involved in neuroimmunomodulatory processes. Previously, it has been demonstrated that 5-HT may induce interleukin (IL)-6 expression in primary rat hippocampal astrocytes. The present study was undertaken to investigate the molecular pathways underlying this induction of IL-6 synthesis. As a model system, we used the human astrocytoma cell line U373 MG, which synthesizes IL-6 upon stimulation with various inducers. 5-HT dose- and time-dependently induced IL-6 protein synthesis. We identified several 5-HT receptors to be expressed on U373 MG cells, including the 5-HT1D, 5-HT2A, 5-HT3 and 5-HT7 receptors. In this report, we show that the 5-HT-induced IL-6 release is mediated by the 5-HT7 receptor based on several agonist/antagonists that were used. 5-HT-induced IL-6 synthesis is inhibited by the partially selective 5-HT7 receptor antagonist, pimozide, and the selective antagonist SB269970. Furthermore, IL-6 synthesis was induced by the 5-HT7 receptor agonist carboxamidotryptamin. In addition, we found p38 MAPKs and protein kinase C (PKC) epsilon to be involved in 5-HT-induced IL-6 synthesis as specific inhibitors of these enzymes (SB202190 and RO-31-8425, respectively) blocked 5-HT-induced IL-6 synthesis. Furthermore, 5-HT mediated the phosphorylation of both p38 MAPK as well as the PKC epsilon isoform. The p42/44 MAPKs, however, were not involved in 5-HT-induced IL-6 synthesis. This study shows, for the first time, a central role of 5-HT7 receptor linked to p38 MAPK and PKC epsilon for the induction of cytokine synthesis in astrocytic cells.
The particle properties and luminescence properties of Gd2O3:Eu using solution-combustion with various Eu content were analysis (2008)

In this study, the particle properties and luminescence properties of Gd2O3 nano powder with various Eu content were studied. Gd2O3:Eu nano powder was fabricated using special solvent which mixed the alcohol and the distilled water at specific ratio. This solvent by the solution method showed short fabrication time because solution time of Gd and Eu was reduced. From this experiment with Gd2O3:Eu, the particle properties og nano powder phosphor way analysed using SEM (scanning electron microscope) and EDX(Energy Dispersive X-ray). Also the luminescence properties of nano powder was measured using PL(Photoluminescence) and CL (CathodeLuminescence). The size of powder was 30nm~40nm. The magnitude of powder showed the best peak at 620nm. Among 1,3,5wt% of Eu content, the more Eu content was added in powder, the more photons wre generated. Also it shows luminescence efficiency was improved adding 5% of Eu content.
Resilient and Trustworthy Dynamic Data-driven Application Systems (DDDAS) Services for Crisis Management Environments (2015)

Future crisis management systems needresilient and trustworthy infrastructures to quickly develop reliable applications and processes, andensure end-to-end security, trust, and privacy. Due to the multiplicity and diversity of involved actors, volumes of data, and heterogeneity of shared information;crisis management systems tend to be highly vulnerable and subjectto unforeseen incidents. As a result, the dependability of crisis management systems can be at risk. This paper presents a cloud-based resilient and trustworthy infrastructure (known as rDaaS) to quickly develop securecrisis management systems. The rDaaSintegrates the Dynamic Data-DrivenApplication Systems (DDDAS) paradigm into a service-oriented architectureover cloud technology andprovidesa set of resilient DDDAS-As-A Service (rDaaS)components to build secure and trusted adaptable crisis processes. The rDaaSalso ensures resilience and security by obfuscating the execution environment andapplying Behavior Software Encryption and Moving Technique Defense. A simulation environment for a nuclear plant crisis managementcase study is illustrated to build resilient and trusted crisis response processes.
Unconventional microfluidics: expanding the discipline (2013)

Since its inception, the discipline of microfluidics has been harnessed for innovations in the biomedicine/chemistry fields-and to great effect. This success has had the natural side-effect of stereotyping microfluidics as a platform for medical diagnostics and miniaturized lab processes. But microfluidics has more to offer. And very recently, some researchers have successfully applied microfluidics to fields outside its traditional domains. In this Focus article, we highlight notable examples of such "unconventional" microfluidics applications (e.g., robotics, electronics). It is our hope that these early successes in unconventional microfluidics prompt further creativity, and inspire readers to expand the microfluidics discipline.

Classification of human motion using radar micro-Doppler signatures with hidden Markov models (2016)

One of the desirable features in a ground surveillance radar is to provide information about what a detected person is doing. This would give a law enforcement organization ability to detect suspicious activities remotely and act accordingly. Previously, micro-Doppler radar signatures from humans were shown to have the necessary features to make that distinction. Typically, micro-Doppler signal spectrograms are used to obtain features to classify what the person is doing. However, most of these techniques treat the spectrogram as an image, and obtain features through some image processing techniques. In this work, we propose the use of hidden Markov models as an alternative method to statistically model both instantaneous and correlated long-term variations within the micro-Doppler signal to classify a motion. In addition, we propose use of principle component analysis (PCA) as a data driven feature extraction approach that captures vital statistics of the input at a much reduced dimension. Experiments show that with the proposed methods, perfect classification of four different motions can be attained when training and testing set both contains data from same people, and 90% accuracy is obtained when training and testing set has data from different people.
