New Results Improve Fracture Cleanup Characterization and Damage Mitigation (2006)

Abstract It is well documented in the literature that hydraulic fracture treatments, although successful, often underperform: Frac and Pack completions exhibit positive skin values, and traditional hydraulic fracture completions show discrepancies between the placed propped length and the effective production fracture length. Ineffective fracture clean-up is often cited as a likely culprit. This paper presents some of the results of an investigation of fracture clean-up mechanisms. This investigation was undertaken under a Joint Industry Project (JIP) active since the year 2002. The data discussed builds on the initial results published in early 2006, which indicated that the polymer concentrates only in the filter cake and that flow along the fracture encounters significant yield stress when the filter cake cumulative thickness dominates the width of the fracture. The new results presented here demonstrate successful strategies that mitigate the effects of excessive filter cake thickness. Experimental data demonstrate that flow along the fracture would encounter lower yield stress when the breaker is delivered directly to the filter cake as opposed to randomly distributed. The data also indicate that a smaller breaker amount delivered directly into the filter cake is more effective at reducing the yield stress effects than a larger breaker amount delivered randomly in the slurry. Alternative breaker materials are explored and additional data are also presented to estimate the yield stress effect for fluid flow across the filter cake from the reservoir into the fracture.
Developing a long-term surviving piglet model of neonatal hypoxic-ischemic encephalopathy (2005)

When subjected to acute hypoxia-ischemia, piglets were likely to survive only if they were given such supportive measures as anesthesia and mechanical ventilation. Even with hypoxic-ischemic injury sufficient to produce acute signs of neurological dysfunctions, longterm, stable survival with no evident brain histopathological abnormalities was possible.
Molecular Diversity of Tonghaosu: Synthesis of Lactam-Containing Tonghaosu Analogs (2003)

A new type of tonghaosu analogs containing spiroketal and lactam functionality was synthesized from methyl 2-furoate and amino alcohols. The stereoselective control of spiroketal chirality was also explored.
A simple TMS320C31 DSP-PC bus interface circuit (2002)

This paper describes a specific 8-bit data interface circuit for the digital signal microprocessor TMSC320C31 from Texas Instruments. This DSP can be connected to any bus through a similar interface discussed here. The interface's simplicity and functionality are the key for such usage in the Telecommunications Institute-Pole of Coimbra. The low cost interface only consists of four ICs, a 2K/spl times/8 dual-port static RAM, two 20-pin PALs and a 20-pin data transceiver circuit. It has firstly been part of an H.261 video encoder board and then used in other PC boards such as an ISDN, an 11.261 video decoder and a QCIF video codec, all on an ISA bus. This interface is now being implemented on a PCI bus in our laboratories.
Investigation in Wireless Power Transmission for UAV Charging (2015)

This paper proposes application of wireless power transfer for charging of electric-powered Unmanned Air Vehicles (UAV)s. Multi-rotor systems, such as quadrotors, are light-weight and easy to operate. They are available in different sizes and with the wide range of capabilities. The main limitation of electric-powered UAVs is their range and endurance, due the limited battery capacity. Increasing battery system size is not a viable solution as its weight becomes a limiting factor. Supercapacitors are not an option, because of their low energy density. An alternative is to recharge UAV on the job, using wireless energy transfer (WET). WET was originally investigated by Nikola Tesla in the beginning of the 20th century. His patents are now common ground for any power transmission technology research, both wired and wireless. Investigations in resonance-based wireless energy transfer promise efficient wireless power transmission over several meters. This offers an ability to recharge moving vehicles, such as cars, trains and UAVs, wirelessly. For example, this technology can be applied to extend the range of UAVs used for the inspection of power transmission lines and towers. Presented project investigate capabilities and limitations of the wireless power transmission, for particular UAV application, i.e. for the infrastructure inspections.

Polarity detection in ultrasound current source density imaging (2016)

Modulating the electric dipole field with ultrasound pulse, ultrasound current source density imaging (UCSDI) can detect current direction and form spatial 3D imaging of dipole changing in one period of treatment. As ultrasound pulse passes through the conductive media, it convolves/correlates with the inner product of the electric field of a dipole and lead field of a pair of detectors, making the shifting frequency of polarity lower than the center frequency of the ultrasound pulse. After acoustoelectric (AE) signal is shifted to base band, the AE voltage is positive at anode and negative at cathode. In the simulation, the lead fields of detectors and electric field of dipole were calculated by the finite element (FE) method; the convolution and correlation in the computation of AE signal were accelerated using 3-D fast Fourier transforms. The current direction and amplitude are encoded in the phase and amplitude of the AE signal. Based on the analysis of polarity algorithms on the simulated and in-vitro ultrasound current source density images, it is concluded that the cross-correlation method is significantly better than the autocorrelation method to extract the frequency shift for high pulse bandwidth.

Gastrointestinal motility enhancing effect of ginger and its active constituents. (1990)

The effect of ginger root (Zingiberis Rhizoma) on gastrointestinal motility was examined based on its ability to enhance charcoal meal transport in mice. Oral administrations of the acetone extract of ginger (which contains volatile oils and bitter substances) at 75 mg/kg, [6]-shogaol at 2.5 mg/kg, or a [6]-, [8]- or [10]-gingerol at 5 mg/kg enhanced the transport of a charcoal meal. The effects of these substances were similar to or slightly weaker than those of metoclopramide and donperidone.
Different Molecular Events Result in Low Protein Levels of Mannan-Binding Lectin in Populations from Southeast Africa and South America (1998)

Previous studies have shown that three point mutations in exon 1 and a particular promoter haplotype of the mannan-binding lectin (MBL) gene lead to a dramatic decrease in the serum concentration of MBL. In this study, MBL genotypes and serum concentrations were determined in unrelated individuals in a population from Mozambique (n = 154) and in two native Indian tribes from Argentina (i.e., the Chiriguanos (n = 43) and the Mapuches (n = 25)). In both populations, the MBL concentrations were low compared with those found in Eskimo, Asian, and European populations. In Africans, the low serum concentrations were due to a high allele frequency (0.24) of the codon 57 (C) variant, which resulted in a high frequency of individuals with MBL deficiency (0.06), and were also due to the effect of a relatively high frequency (0.13) of low-producing promoter haplotypes. The low concentrations in the South American populations were primarily due to an extremely high allele frequency of the codon 54 (B) variant in both the Chiriguanos (0.42) and the Mapuches (0.46), resulting in high frequencies of individuals with MBL deficiency (0.14 and 0.16, respectively). In the search for additional genetic variants, we found five new promoter mutations that might help to elucidate the evolution of the MBL gene. Taken together, the results of this study show that different molecular mechanisms are the basis for low MBL levels on the two continents.
Neonatal chest wall suspension splint: A novel and noninvasive method for support of lung volume (2005)

Surfactant and musculoskeletal immaturity results in lower compliance of the lung relative to the chest wall, with clinical manifestations of low lung volume, marked chest wall retractions (CWR), and thoracoabdominal asynchrony. Inspiratory efforts are dissipated on distorting the chest wall inward rather than recruiting lung volumes. The current study tests the hypothesis that a novel neonatal chest wall suspension splint (SP), designed to provide stability to the compliant chest wall, would reduce inspiratory chest wall retractions and improve lung volumes. Nine preterm infants (29 +/- 1 SE weeks of gestation; 1.59 +/- 0.27 SE kg study weight) were studied at 16 +/- 5 SE days of life at baseline (BL) and following application of the front plate (FP) and the full SP (Hug n Snug Neonatal Chest Splint, Respironics, Inc.). Phase angle of thoracoabdominal motion, CWR, functional residual capacity (FRC), and pulmonary function were evaluated during spontaneous breathing. Compared to BL, there was a significant decrease in anterior CWR (2.21 +/- 0.91 SE vs. 0.25 +/- 0.09 SE mm; P < 0.05), an increase in FRC (16.6 +/- 2.8 SE vs. 27.8 +/- 5.5 SE ml/kg; P < 0.05) and tidal volume (4.8 +/- 1.5 SE vs. 7.3 +/- 1.4 SE ml/kg; P < 0.05), minimal effect on pulmonary compliance (1.98 +/- 0.50 SE vs. 1.72 +/- 0.30 SE ml/cmH2O/kg), and a trend for a decrease in phase angle (128.4 +/- 10.9 SE vs. 111.8 +/- 19.3 SE) with the application of the splint. FRC correlated inversely with severity of CWR across all conditions (P < 0.05, r = -0.68). Phase angle was directly correlated to anterior CWR (r = 0.72; P < 0.05) and correlated inversely with FRC (P < 0.005; r = -0.56). We speculate that by improving CW stability, the use of this splint may reduce the energetic requirements of breathing and, potentially, the need for more invasive ventilatory support in the neonate.
Smart Routing: A Novel Application of Collaborative Path-Finding to Smart Parking Systems (2014)

We utilise collaborative path-finding to improve efficiency of smart parking systems and therefore reduce traffic congestion in metropolitan environments, while increasing efficiency and profitability of parking garages. A significant portion of traffic in urban areas is accounted for by drivers searching for an available parking space. Many cities have adopted a parking guidance and information system to try to alleviate this traffic congestion. Typically these systems entail informing the driver of the whereabouts of an available space, reserving that space for the specific driver, and providing directions to reach the destination. Little or no account is taken of how much congestion will be caused by multiple drivers being directed to the same car-park concurrently. We introduce the concept of collaborative path-finding to the problem. We simulate a smart parking system for an urban environment, and show that a novel approach to collaboratively planning paths for multiple agents can lead to reduced traffic congestion on routes toward busy parking areas, while reducing the amount of time when parking spaces are vacant, thereby increasing the revenue earned.
A Double-blind Study of the Effectiveness of Cyclosporine in Amyotrophic Lateral Sclerosis (1988)

In a double-blind placebo-controlled trial of cyclosporine in amyotrophic lateral sclerosis, no differences were observed in the monthly rate of progression or the relative risk of progression in comparing 38 patients randomized to the placebo group and 36 patients randomized to the cyclosporine group. In comparing three subgroups of patients, cyclosporine appeared to benefit men who entered the study within 18 months of the onset of first symptoms, whereas it was of no value to women or to men who entered later than 18 months. For the men with recent onset of disease, the relative risk of progression was 0.403; the monthly rate of progression was 5.2 +/- 1.1 points with placebo and 3.5 +/- 0.7 points with cyclosporine. These provocative results support the need for a full study of cyclosporine in men with recent onset of disease.
Long synthetic peptides encompassing thePlasmodium falciparum LSA3 are the target of human B and T cells and are potent inducers of B helper, T helper and cytolytic T cell responses in mice (2001)

We synthesized 17 long synthetic peptides (LSP) spanning the whole 200-kDa Plasmodium falciparum liver stage antigen-3 (LSA3), an antigen that induces protection in chimpanzee, and analyzed their immunogenicity in BALB/c mice and their antigenicity in individuals living in a hyper-endemic malaria area. Our findings show that both specific antibodies and T cell proliferation against most LSA3-LSP develop in malaria-exposed adults. All individuals studied had detectable antibodies against a minimum of 6 and a maximum of 15 polypeptides. It is noteworthy that antibody prevalence and titers were as high against non-repeat as repeat regions. Although the extent of T cell reactivity was lower than that observed for B cells, most of the sequences contained at least one T helper epitope, indicating that the majority of LSA3-LSP contain both B and T cell epitopes within the same sequence. Injection of LSA3-LSP with SBSA2 adjuvant in mice, showed strong immunogenicity for most of them, eliciting both T cell responses and specific antibody production. While all the peptides were immunogenic for B cells, different patterns of T cell responses were induced. These peptides were thus classified in three sets according to the levels of the T cell proliferative and of the IFN-γ-specific responses. Importantly, antibodies and T cells against some of the LSP were able to recognize LSA3 native protein on P. falciparum sporozoites. Additionally, some LSP (44–119, 1026–1095, 1601–1712) also contained epitopes recognized by H-2d class I-restricted T cells. These results led to the identification of numerous domains that are highly antigenic and immunogenic within the LSA3 protein, and underline the value of the LSP approach for vaccine development.

CARD-Bcl10-Malt1 Signalosomes: Missing Link to NF-κB (2007)

CARD11 (CARMA1), Bcl10, and Malt1 are required for nuclear factor NF-kappaB activation in response to antigen recognition. Initially, gene disruption experiments in mice pointed to a lymphocyte-specific role for CARD11-Bcl10-Malt1 complexes. However, strong evidence suggesting that conserved Bcl10-Malt1 complexes interact with different CARD scaffolds to connect various receptors in different cell types to NF-kappaB signaling has emerged more recently. The CARD10 (CARMA3)-Bcl10-Malt1 signalosome functions as a link between G protein-coupled receptor (GPCR) signaling and proinflammatory NF-kappaB activation. Further, Dectin-1-induced antifungal responses to NF-kappaB in dendritic cells depend on CARD9-Bcl10-Malt1. These results identify CARD-Bcl10-Malt1 signalosomes as pivotal regulators that link not only innate and adaptive immune responses, but also GPCR signaling, to the canonical NF-kappaB pathway.
Combination of two anti‐<scp>CD</scp>5 monoclonal antibodies synergistically induces complement‐dependent cytotoxicity of chronic lymphocytic leukaemia cells (2013)

The treatment of chronic lymphocytic leukaemia (CLL) has been improved by introduction of monoclonal antibodies (mAbs) that exert their effect through secondary effector mechanisms. CLL cells are characterized by expression of CD5 and CD23 along with CD19 and CD20, hence anti-CD5 Abs that engage secondary effector functions represent an attractive opportunity for CLL treatment. Here, a repertoire of mAbs against human CD5 was generated and tested for ability to induce complement-dependent cytotoxicity (CDC) and antibody-dependent cell-mediated cytotoxicity (ADCC) both as single mAbs and combinations of two mAbs against non-overlapping epitopes on human CD5. The results demonstrated that combinations of two mAbs significantly increased the level of CDC compared to the single mAbs, while no enhancement of ADCC was seen with anti-CD5 mAb combinations. High levels of CDC and ADCC correlated with low levels of Ab-induced CD5 internalization and degradation. Importantly, an anti-CD5 mAb combination enhanced CDC of CLL cells when combined with the anti-CD20 mAbs rituximab and ofatumumab as well as with the anti-CD52 mAb alemtuzumab. These results suggest that an anti-CD5 mAb combination inducing CDC and ADCC may be effective alone, in combination with mAbs against other targets or combined with chemotherapy for CLL and other CD5-expressing haematological or lymphoid malignancies.
Cellulose Nanofiber Composite Substrates for Flexible Electronics (2012)

Flexible electronics have a large number of potential applications including malleable displays and wearable computers. The current research into high‐speed, flexible electronic substrates employs the use of plastics for the flexible substrate, but these plastics typically have drawbacks, such as high thermal expansion coefficients. Transparent films made from cellulose nanofibers have low thermal expansion and thus the potential to serve as substrates for flexible electronics. Here we present the results of using a cellulose nanofiber composite substrate for flexible electronics. While the initial processing procedures need improvement to reduce the film surface roughness and composite thermal expansion coefficient, a working prototype was built and is reported here.
Topical Use of Mechlorethamine in the Treatment of Psoriasis (1972)

We have presented the results of treatment of 57 patients with psoriasis with topically applied mechlorethamine. Attempts to induce immunological tolerance to this chemical in 12 patients were unsuccessful. Although this is a useful treatment for psoriasis the high incidence of sensitization precludes its use until some method can be devised to prevent this complication.
High-Gain Transimpedance Amplifier With DC Photodiode Current Rejection (2005)

This master's thesis deals with the design of a differential high-gain transimpedance amplifier in TSMC's 0.18 um mixed signal process that utilizes a DC photodiode current cancellation loop and a switching automatic gain control (AGC) with a bilinear gain curve. The amplifier is designed to satisfy the demands of Optical Coherence Tomography applications where the receiver is expected to measure the envelope power of an amplitude modulated sinusoidal optical signal that incorporates a large DC component. Methods of increasing dynamic range and gain linearity through the use of DC photodiode current cancellation and bilinear gain are explored. Effects of changing DC photodiode current on the overall system response is also demonstrated.
Circulating FSH isoform patterns during recurrent increases in FSH throughout the oestrous cycle of heifers (1997)

Blood samples were collected from heifers (n = 6; 450 +/- 7.7 kg) 2-4 times a day during the first and second follicular waves, and during the gonadotrophin surge to determine whether changes in circulating FSH isoforms occur during cyclic quantitative changes in FSH throughout the oestrous cycle. Serum was assayed for FSH, LH, oestradiol and progesterone. Selected samples collected during the first (samples 1-3) and second (samples 4-6) postovulatory recurrent FSH increase and during the subsequent gonadotrophin surge (samples 7 and 8) were analysed for FSH isoforms by chromatofocusing. No change (P > 0.05) in isoform profile occurred during the first or second recurrent FSH increase, when oestradiol concentrations were 0.6 +/- 0.07 and 0.6 +/- 0.09 pg ml-1 and progesterone concentrations were 0.03 +/- 0.01 and 2.4 +/- 0.19 ng ml-1, respectively. The percentage of FSH eluting in the pH range 7.4-7.0 increased (P < 0.05) from 14.2 +/- 2.2 during the luteal phase (samples 1-6) to 20.2 +/- 2.3 (sample 7) and 31.4 +/- 3.4% (sample 8) during the preovulatory gonadotrophin surge, while oestradiol concentrations were higher (P < 0.05; 4.9 +/- 0.39 pg ml-1) than in the luteal phase of the cycle. In summary, FSH isoform patterns did not change during the cyclic quantitative changes in FSH associated with emergence of the first or second follicular wave. However, during the gonadotrophin surge, in association with increased oestradiol concentrations, an increase in the amount of less acidic isoforms of FSH was observed. Therefore, qualitative changes in FSH are not important in the physiological regulation of follicle turnover during the luteal phase of the oestrous cycle of heifers.
