Indispensible Replication Restart Helicase PriA Aids Bacterial Survival: A SMART Team Story (2013)

Approximately one disruption in DNA replication occur every cell cycle in bacteria leading to partially duplicated chromosomes. Since unfinished replication can result in genome instability and cell death, bacteria need a mechanism to reload the replication machinery onto the genome. Known as the replication restart primosome (RRP), several proteins function to reload the replicative helicase onto abandoned replication forks, restarting DNA replication. PriA is the most conserved member of the RRP, initiating the dominant replication restart pathway. A helicase, PriA remodels collapsed forks and serves as a platform for binding of other primosomal proteins. The Madison West High School Students Modeling a Research Topic (SMART) Team modeled PriA using 3D printing technology. PriA is a multi‐domain protein and residues important for DNA binding, ATP hydrolysis, and helicase activity are modeled. Since DNA replication restart pathways are essential in preserving genomic integrity and cell viability in bacteria, studies of PriA offer an approach to developing novel antibacterial compounds.

Suppressing oxidization of hydrogen silsesquioxane films by using H/sub 2/O plasma in ashing process (2002)

We have found that H/sub 2/O plasma is very effective in suppressing degradation of HSQ (hydrogen silsesquioxane) films when removing photoresist from their surfaces. H/sub 2/O plasma treatment causes little Si-H oxidization in HSQ films. Increases in the dielectric constant and leakage current of HSQ films treated by H/sub 2/O plasma is much smaller than those of films treated by O/sub 2/ plasma.
ZnO nanowires and PbS quantum dots for third-generation solar cells (2014)

Nanowires and quantum dots hold promising potency to enhance the performance of solar cells by improving light absorption, light trapping, exciton generation, and photoexcited-carrier collection. Quantum dot sensitized solar cells consist of three components: semiconductor quantum dots, one dimensional metal oxide n-type and hole-transport layer materials. In this paper, we present the synthesis and characterization of ZnO nanowires (as an electron acceptor) decorated with lead sulfide (PbS) quantum dots (as an electron donor unit) for photovoltaic applications. In addition to this, the electron injection rate from PbS quantum dots to ZnO nanowires will be discussed
Transformation of the Bricker to a continent urinary reservoir to eliminate severe complications of uretero-ileostomy performed in eight patients among 200 Bricker. (1995)

Between 1969 and 1994 urinary diversion via the ileal loop (Bricker's operation) was performed in 200 patients. After introduction of methods of continent urinary diversion into clinical practice, some of young patients operated in childhood for congenital lower urinary tract malformations demanded the conversion of the primary diversion. The decision was influenced, however, not only by subjective complaints but also by severe complications having relation to the long-lasting presence of stoma. A modified Mainz pouch I, with a catheterizable stoma was constructed in 6 patients with primary uretero-ileostomy made 7 to 22 years prior to conversion because of exstrophy of the urinary bladder or a neurogenic bladder with total urine incontinence. The ileal loop used for uretero-ileostomy was detubularized or combined with additional segments of ileum and colon. The ileal stoma was connected to the umbilicus. In other two patients suffering from a neurogenic bladder the uretero-ileostomy was converted to an orthotopic ileal pouch. The authors present long-term results (1.5 to 7 years) of follow-up with urodynamic and radiological evaluation. The results both compensate the urologist's efforts and enhance the patient's quality of life.
Real time holographic recording materials (1974)

Abstract : A number of high-quality, dry-working recording materials were evaluated to determine their suitability for holographic data storage and optical data processing applications. Sensitometric, holographic, and systems data were generated. With the RADC-sponsored HRMR system a frame of reference, several film/systems studies were completed that have an important practical impact. In particular, the feasibility of making high-quality fiche replications using straightforward contact copying techniques was demonstrated. The overall conclusion of the study was that some dry-working recording materials could become systems qualified in the near-term.
Immunohistochemical expression of 14‐3‐3 sigma protein in human urological and gynecological tumors using a multi‐tumor microarray analysis (2005)

14-3-3 sigma is an exclusive epithelial marker and data on its expression in different malignancies are very scarce. The aims of the present study are to screen its expression in the most common neoplasms occurring in the urological and gynecological tract and to evaluate its use as a diagnostic marker. A tissue microarray was constructed using 350 samples from 13 different neoplasms. Immunohistochemical analysis using a polyclonal 14-3-3 sigma antibody was performed. Overall, this protein was positive in 141 and negative in 209 tumors. The most frequent expression was seen in squamous cell carcinoma of the cervix and urothelial bladder carcinoma, followed by prostatic and endometrial adenocarcinoma. 14-3-3 sigma was able to distinguish prostate adenocarcinoma from urothelial bladder carcinoma, with an odds ratio of 0.028 (P = 0.001; 95% CI, 0.0003-0.222), and distinguish seminoma from embryonal carcinoma of the testis, with an odds ratio of 0.061 (P = 0.009; 95% CI, 0.007-0.5014). It also has a good value in differentiating renal clear cell carcinoma from papillary carcinoma, with an odds ratio 0.470 (P < 0.001; 95% CI, 0.008-0.261). 14-3-3 sigma seems to have good potential use as an epithelial marker, after confirmation with further targeted studies. Finally, as with all immunohistochemical markers, we can optimize the utility of this protein to distinguish tumor mimics by including it in an appropriate immunohistochemical panel.
DNA-binding Properties of the p53 Tumor Suppressor Protein (1994)

The p53 tumor suppressor gene product plays a pivotal role in cells by transmitting a signal from damaged DNA to genes that regulate the cell cycle and apoptosis (Donehower and Bradley 1993; Levine 1993; Prives and Manfredi 1993). Central to its function in this capacity is its ability to bind specifically to DNA (Vogelstein and Kinzler 1992). p53 activates transcription from promoters that contain p53-binding sites (Vogelstein and Kinzler 1992). Identified genes that contain such p53 response elements, which are activated in cells upon DNA damage and subsequent accumulation of p53, include GADD45 (Kastan et al. 1992), mdm2 (Wu et al. 1993), and WAF1/p21 (El-Deiry et al. 1993). The interest in p53 that stems from its unique and critical role in a DNA damage signal transduction pathway is reinforced by, and indeed possibly subsidiary to, the fact that mutation of the p53 coding sequence occurs with extraordinarily high frequency in...
Spectral Analysis in Walking Balance by Elderly Subjects (2006)

Elderly people lose their rhythm of walking balance, because their body alignment and standing balance become less stable through aging. The fluctuations of both hips movement while walking were measured using a portable measurement system with two accelerometers. Before they have had physical exercise and when walking without shoe insoles, the fluctuations of the hip movement, having back and knee pain, was not rhythmic, and also not proportional to 1/f (f=frequency) fluctuation, their walking was unstable. After physical exercise and walking with insoles, their walking became rhythmic and was approximately close to proportional to 1/f fluctuation, and their walking improved. This study provides useful information for the improvement of walking.
Intermodal and intramodal dispersion measurements on 1.3 μm single-mode fibre for use at 0.85 μm (1988)

Intermodal dispersion at 0.85 μm, and intramodal dispersion in the range 0.75 to 1.5 μm has been measured on single-mode fibres for use at 1.3 μm. Results in good agreement with theoretical predictions show the fibres to be under-compensated at 0.85 μm. The pulse spreading at 0.85 μm in such fibres owing to intramodal dispersion is 0.24 ns/km for a 3 nm linewidth source.
Fiber Optic Pressure Sensing Array. (1994)

Abstract : An optical pressure sensing array is provided for sensing a high-frequency acoustic energy profile. The array is coupled to a reflector that is responsive to high-frequency acoustic pressure variations. The array transmits and receives light energy to and from the reflector. The received light energy is modulated by the movement of the reflector because of the acoustic field. Each element in the optical array is a closely packed geometrical configuration utilizing a single transmit optical fiber surrounded by six receive fibers, all having the same radius. In this configuration, the receive fibers receive light energy only from their associated transmit fiber resulting in a high-resolution acoustic profile. Furthermore, the geometric configuration permits a center-to-center element spacing that optimally is one-half the wavelength of the ultrasonic beam providing the acoustic energy at the operational frequency.
Chronic cough and its association with TB-HIV co-infection: factors affecting help-seeking behaviour in Harare, Zimbabwe (2010)

Some individuals remain reluctant to be investigated for chronic cough even when provided with community-level services, with fear of the connotations of being diagnosed with TB and an aversion to contact with health providers among the dominant themes. In men, deferred acceptance that a chronic cough should be investigated may be related to concepts of masculinity, especially when symptoms are mild.
[Treatment of chronic osteomyelitis in Africa with plaster implants impregnated with antibiotics]. (1989)

Nineteen African patients with osteomyelitis were treated by curettage of the lesions and packing of the bone cavities with plaster of Paris pellets containing antibiotics (Fucidin and Amoxycillin). Of 18 patients followed, 16 showed wound healing in an average of 3 to 6 weeks. Eight patients had regular roentgenographic examinations during a minimum of two months. In six of these patients, healing of the lesions and a significant osteogenic reaction were observed. The plaster pellets were resorbed in 3 to 6 weeks in all patients, and no signs of rejection were noted. In spite of insufficient follow-up due to medical conditions in Africa (Zaire), the study confirms the advantages of this simple treatment of osteomyelitis in underdeveloped countries.
Meridian Hill Park: The making of an American Neoclassical Landscape (2002)

The neoclassical design was the dominant design movement in landscape architecture at the turn of the last century, dictating the form and design of public parks for most of the first half of the twentieth century. Meridian Hill Park, located just north of the White ouse in Washington, DC, is considered the most ambitious neoclassical park ever conceived in the United States. The paper provides an overview of the design development of the park, illustrating how classical design precedents were used to create a contemporary neo-classical park.

We also quantify the increase in annual yield that arises when accounting for indirect light at three example sites with different climates, finding it to be ∼30% lower for a bifacial system than a monofacial system; the gain was 0.8%–1.5% for bifacial systems and 1.1%–2.1% for monofacial systems, where the highest gain was attained in the cloudiest climate.
Chemical Composition, Antioxidant and Antimicrobial Activity of Essential Oil and Extracts of Tragopogon graminifolius, a Medicinal Herb from Iran (2014)

Tragopogon graminifolius DC., family Compositae, is widely consumed as a green vegetable in the west of Iran and for the treatment of gastrointestinal and hepatic ailments. In this study, the chemical composition of the essential oil from T. graminifolius aerial parts was evaluated by gas chromatography and gas chromatography mass spectrometry. Moreover, antioxidant and antimicrobial activity of the essential oil and various extracts of T. graminifolius were determined. Fifty-eight compounds representing 87.2% of the essential oil were identified. The main components were n-hexadecanoic acid (22.0%), beta-caryophyllene (7.5%), heneicosane (6.6%), and nonanal (5.2%). The essential oil demonstrated the highest DPPH radical scavenging activity (56.6 +/- 8.8 ug/mL) and the 80% ethanolic extract the highest ferric reducing antioxidant activity (908.2 +/- 79.5 mmol Fe2+ ion/g extract). The total phenolic content of the 80% ethanolic extract from the aerial parts was the highest (560.7 +/- 18.8 mg/g gallic acid equivalent). In the antimicrobial test, Shigella dysenteriae was the most vulnerable microorganism, followed by Proteus vulgaris, and the essential oil exhibited the highest antibacterial activity among the samples. The results indicated that the essential oil and extracts of T. graminifolius could be consumed as a natural herbal preservative or complementary supplement in the food and pharmaceutical industries.

A Digital Rights Management scheme based on rational share content (2010)

In the traditional DRM(Digital Rights Management) scheme, each user must buy a license for a digital content, and can not share this content with his friends. But,with the development of digital content industry, this model can not promote the development of digital content industry chain effectively, people have come to realize that rational sharing could raise the benefit of multiple parties of the digital content industrial chain, and achieve a all-win development. This paper presents a new DRM scheme based on rational share, we employ a security policy based on tamper-proof hardware, with this policy, the content provider can know and control the upper limit of the number of the share users, but the content provider do not know who buy the content, and how many users share the content. Meanwhile, in our scheme, the digital content which the user brought is portable, the users can access his digital content in any of his devices. This paper focuses on the security policy based on tamper-proof hardware and share scheme,some applications of our scheme is discussed also. With rational applications, our scheme can heighten both the benefits of users and content providers by supporting flexible rational sharing mechanism and privacy protection.
Algorithms for accuracy enhancement in a hardware logic simulator (1989)

In this paper, we describe a hardware multiple delay logic simulator that incorporates efficient timing analyses algorithms for event cancellations, spike and race analyses and oscillation detection. The algorithms are implemented on a set of reconfigurable processors, arranged in a pipelined configuration. Spike analysis is accomplished by dynamic pulse width measurement. Both zero and non-zero delay oscillations are detected. Results of simulating industrial VLSI chips are presented to illustrate the effectiveness of the algorithms with minimal performance penalty.
Particle segregation in spouted beds (1983)

Abstract Particle segregation in spouted beds is shown to result from different trajectories of heavy and light particles in the fountain region, lighter particles tending to scatter more in the radial direction than heavier ones. Some desegregation occurred due to rolling along the inclined annulus surface and due to mixing processes in the spout. Segregation is less severe for overdeveloped fountains, where the particles bounce off the outer wall, and for low bed depths, where the fountain is dilute. Segregation can also be countered by a conical baffle which deflects particles outwards from the core of the fountain.
Shear Strength of Jumunjin Sand according to Relative Density (2008)

The properties of sands pertaining to shear strength have been studied extensively by plane strain and triaxial tests for relative densities above 40%. Unfortunately, properties of sand have not been comprehensively studied for relative density below 40%. An experimental investigation of the shear strength of Jumunjin sand was carried out using a plane strain, triaxial and direct shear apparatus according to relative density ranges from 0 to 100%. Because of the complexity of the shear tests on coarse materials, correlations were developed that would be useful for practical purposes. This article presents a comparison of strength properties' results and their correlation with relative density.
A Multipath Sparse Beamfroming Method (2013)

A novel formulation of beamforming is proposed for acquisition of the signals in reverberant acoustic clutter of interferences and noise. We derive the beamforming methods which incorporate the sparsity structure pertained to the acoustic source distribution and multipath propagation model. The quantitative assessments demonstrate that sparse beamforming enables effective beampattern steering from far fewer samples than the conventional beamformers. In addition, linear constraint on the desired channel rather than the desired direction improves the signal estimation performance in reverberant enclosures.
