Technique for Considering Fluid Compressibility and Temperature Changes in Mini-Frac Analysis (1986)

Abstract An analytical technique has been developed to consider fluid compressibility and temperature changes when making mini-frac analyses. Mini-frac tests in which the effects of compressibility and changing temperatures are ignored can produce results that are as much as 75% in error. However, techniques for mini-frac analysis presented in current petroleum engineering literature are based on the assumption that fracturing fluid is incompressible and isothermal in nature. This paper examines the effects that fluid compressibility and temperature changes have on mini-frac analysis by presenting field cases analyzed by the method developed. The analysis was performed using both PK and CZ models as presented in literature. An example analysis using the PK model showed that when both temperature and compressibility effects are ignored, errors of 300% in calculated fluid loss coefficient and 75% in calculated fracture length are encountered. The same example using CZ models gave 200% and 33% errors in fluid loss coefficient and fracture length, respectively. Correcting for temperature and compressibility effects is considered through the use of "effective pressure drop," or pressure drop the mini-frac would have exhibited if ideal conditions had prevailed. Developing this concept allows the use of already developed type curves. The approach is analogous to pseudo pressure in well testing. When only compressibility effect is considered, only the magnitude and not the shape of ΔP versus dimensionless time graph is changed. Correcting for both temperature change and compressibility changed both shape and magnitude of the curve. It has been observed that a better match was obtained after such correction.

Über intramolekulare Donator-Akzeptor-Wechselwirkungen in N,N′-Dimethylharnstoff-Derivaten des Phosphors / Intramolecular Donor-Acceptor Interactions in N,N′-Dimethylurea Derivatives of Phosphorus (1989)

The reaction of 1 with N, N′-dimethyl-N, N′-bis(trimethyIsilyl)urea, 2 has furnished the compound Me 2 NCH 2 CH 2 N(Me)P(NMe) 2 C(:O), 3. Following oxidation o f phosphorus in 3 through several reagents, intramolecular donor-acceptor interactions were observed when an electronegative group was bonded to phosphorus; this group, activating the phosphorus atom, should be well polarizable in solution and should readily depart from the molecule as an anion. The unusual spirophosphoranes 8, 11 and 12 could thus be synthesized. The reaction of equimolar quantities of MeOCH 2 CH 2 OPCl 2 , 15 with 2 has furnished 16 which is related to 3. Reaction of 15 with excess 2 constitutes a new mode o f formation of the previously reported diphosphorus compound 17.

Effect of D-propanolol on growth and motility of flagellate protozoa (1987)

Propranolol inhibits sperm motility and has been considered as a spermicide contraceptive. In view of the inhibitory effects of D-propranolol on sperm flagellar activity, we have investigated its effect on motility and growth of two human flagellate, protozoan parasites. D-propranolol had a dose-dependant inhibitory effect on motility of Giardia lamblia and Trichomonas vaginalis with ED50s of 0.38 and 0.66 mmol/l respectively, D-propranolol also inhibited growth of both parasites with ED50s of 0.18 and 0.23 mmol/l for Giardia and Trichomonas respectively. D-propranolol, unlike DL-propranolol is devoid of the unwanted effects of beta-blockade, and thus may be a useful antiprotozoal drug particularly after vaginal placement when it is concentrated in vaginal mucus.
New Antifungal Compounds from Aspergillus terreus Isolated from Desert Soil (2012)

Two new butyrolactone I derivatives: 3-[3-hydroxy-4-(3-methyl-but-2-enyl)-phenyl]-5-(-4-hydroxybenzyl)-4-methyl-dihydrofuran-2(3H)-one (1) and (Z)-3-[3-hydroxy-4-(3-methyl-but-2-enyl)-phenyl]-5-(-4-hydroxybenzylidene)-4-methyl-dihydrofuran-2(3H)-one (2), in addition to the previously described (S)-methyl-4-hydroxy-2-[4-hydroxy-3-(3-methyl-but-2-enyl)-benzyl]-3-(4-hydroxy-phenyl)-5-oxo-2,5-dihydro-furan-2-carboxylic acid methyl ester (3), were identified from a strain of Aspergillus terreus Thom (Trichocomaceae) isolated from desert soil. The antifungal activities of both intra- and extracellular metabolites of A. terreus grown on yeast extract sucrose and malt extract media were determined. Only the secondary metabolites of A. terreus grown on yeast extract sucrose medium were active against Aspergillus fumigatus RCMB 002008. The antifungal activity of A. terreus was attributed to the presence of the compounds (1) and (2), whose minimum inhibitory concentrations (MIC) against A. fumigatus were found to be 32.00 and 16.00 µg/mL respectively. Structure elucidation was carried out using UV spectrometry, electrospray ionization mass spectrometry (ESIMS), high resolution electron impact (HREIMS) spectrometry, (1)H- and (13) C-NMR, proton-proton correlation spectroscopy ((1)H-(1)H Cosy), distortionless enhancement by polarization transfer (DEPT), heteronuclear single quantum coherence (HSQC) and heteronuclear multiple bond correlations (HMBC) spectroscopy.

Robot learning of everyday object manipulations via human demonstration (2010)

We deal with the problem of teaching a robot to manipulate everyday objects through human demonstration. We first design a task descriptor which encapsulates important elements of a task. The design originates from observations that manipulations involved in many everyday object tasks can be considered as a series of sequential rotations and translations, which we call manipulation primitives. We then propose a method that enables a robot to decompose a demonstrated task into sequential manipulation primitives and construct a task descriptor. We also show how to transfer a task descriptor learned from one object to similar objects. In the end, we argue that this framework is highly generic. Particularly, it can be used to construct a robot task database that serves as a manipulation knowledge base for a robot to succeed in manipulating everyday objects.
IR-HARQ vs. Joint Channel-Network coding for Cooperative Wireless Communication (2011)

Abstract—Wireless communication systems demand the use of many coding techniques for data retransmission between sending and receiving end points to achieve the required system capacity over variant channel conditions. Different developed techniques are introduced such as channel coding, network coding and joint coding to achieve this target. As an improvement for wireless communication systems, cooperative wireless communication is illustrated to increase system throughput and enhance system capacity. This paper investigates different data retransmission schemes in cooperative wireless communication systems scenario. More specifically, two considered techniques are compared, Incremental redundancy Hybrid Automatic repeat Request (IR-HARQ) and joint Channel Network coding (NC-HARQ) from throughput and complexity perceptions. The system throughput is derived in both cases to compare the advantages and disadvantages for each technique. Simulations are conducted for different number of end-point receivers to confirm obtained results persistence and trends. Both simulations and theoretical analysis confirm the advantages of the IR-HARQ over the NC-HARQ. Higher throughput and better system capacity is introduced using IR-HARQ when it is compared with NC-HARQ, in addition to decreasing retransmission complexity.
A sparse-coding based approach to clothing image retrieval (2012)

In this paper, we present a sparse-coding based clothing image retrieval method. Our proposed method utilizes multiple types of low and high-level features such as clothing type, color, and appearance to describe an input clothing image. Based on the recent success of sparse representation, we advance a locality-sensitive sparse coding framework on the derived features for retrieving relevant instances from a clothing image collection. Compared with prior image retrieval or recommendation methods which either aimed at determining a proper similarity measure or required the knowledge or preference of prior users, our sparse-coding based approach is able to identify the most similar data instances based on its content information. From our experimental results on a real-world commercial clothing image dataset, we not only verify the effectiveness of our proposed framework, we also confirm that our approach outperforms baseline and state-of-the-art clothing image retrieval methods.
Criminal forensic: An application to EEG (2015)

In the recent years, especially during the last decade electroencephalography (EEG) based brain computer interface (BCI) have become a prevailing study of neuroscience, machine learning and rehabilitation. A BCI provides an arena for a human brain to communicate with a computer directly without the normal neurophysiologic pathways. The electrical signals of the brain, with their fast responsivity with cognitive processes are most suitable as non-motor control mediation between the human and a computer. This can serve as a communication and control channel for various applications. One of the most intriguing uses of EEG is in forensic investigation, used as a tool in lie detection. Lie detection technology has been applied increasingly to investigate and solve criminal cases. Though the contributions of neurobiological research to forensic technology remain largely hypothetical, the evidences appear promising and further research is both feasible and warranted. The brain based lie detection may veritably give solution to many complicated investigation. This paper explores the evolvement of lie detection technology, their working principles, the latest development, and the prospect of their application in forensic science.
Febrile seizures are associated with mutation of seizure‐related (SEZ) 6, a brain‐specific gene (2006)

Genetic factors contribute significantly to the etiology of febrile seizures (FS), the most common type of seizures in childhood. However, in most patients with FS, the causative gene is unknown. The purpose of this study was to explore the relationship between human brain-specific gene SEZ-6 and FS. Through amplification of genomic DNA by PCR and sequencing of the resulting products, we screened 75 subjects for mutations in the coding region (17 exons) of the SEZ-6 gene. Fifteen subjects were healthy individuals and 60 subjects had FS. Patients with FS could be divided into sub-groups based on seizure type (42 simple and 18 complex) and family history (41 had a positive family history). All patients have been followed to date to evaluate seizure recurrence and the development of epilepsy. No mutations were found in healthy controls, but 21 of the patients with FS had mutations in SEZ-6, and the most common type of mutation was a heterozygous, cytosine insertion (frame shift mutation) at position 1435 of the cDNA. The mutation incidence was significantly higher in patients with complex FS (vs. simple FS) and in patients with a positive family history. Sixteen of 42 patients with simple FS experienced seizure recurrence during the 1-5-year follow-up period. Fifteen of 18 patients with complex FS also experienced a recurrence during this period. Among these patients with recurrences, five patients with simple FS and six patients with complex FS have developed epilepsy. The mutation incidence among these epileptic patients is 72.7%. The human SEZ-6 gene is related to the occurrence and development of FS and may be a novel candidate gene for epilepsy. Screening for mutations in SEZ-6 may be valuable in predicting FS recurrence or the development of epilepsy.
The Chemical Behavior of Low Valence Sulfur Compounds. V. Decomposition and Oxidation of Tetrathionate in Aqueous Ammonia Solution (1970)

Abstract The decomposition and oxygen oxidation of tetrathionate in aqueous ammonia solution have been investigated. In the decomposition, thiosulfate, sulfate and sulfamate were formed through penta- and trithionate as intermediate compounds. The molar ratio of the products (SO42−+SO3NH2−)/S2O32− was roughly equal to 2/7, where 0.1n ammonia solution was used. The deficient use of ammonia made the solution neutral or weakly acidic and the precipitation of sulfur and the formation of higher polythionates were observed. The polythionate was detected by means of TLC (Thin Layer Chromatography). In the oxidation, tetrathionate was supposed to go through the following three sequent steps. 1) Decomposition of tetrathionate to form thiosulfate, tri- and pentathionate, and further decomposition of pentathionate to thiosulfate. 2) Oxidation of thiosulfate to tetrathionate and partly to sulfate. 3) Decomposition of trithionate to form sulfate, sulfamate and thiosulfate.
Compatibility Assessment of Crude Oil Blends Using Different Methods (2017)

Today, opportunity crude oils and their blends have attracted the attention of oil companies looking to increase their cross refinery margin. However, when crude oils are blended in the wrong proportions or even the wrong order, they can precipitate asphaltenes (called incompatibility). Once precipitated, it is difficult to re-dissolve asphaltenes quickly. Meanwhile, asphaltenes precipitation is a common problem for oil production companies and refiners and can cause foul preheats exchangers, and catastrophic coking of distillation furnace tubes. If this happens, refineries can lose more than the advantage of purchasing the crude. This paper focused on possibility of transporting crude oil blends (Sarir, Messla, Nafoura and Amna) through 34 inch Sarir pipeline about 512 km to Hariqha Seaport, prior to blending the crude oils have to be compatible in order to avoid phase out and precipitation of asphaltenes. This work discusses the compatibility of Libyan crude oils as a model system. Various simple techniques were investigated to the determination of insolubility number (IN) and solubility blending number (SBN) and the prediction of a compatibility scale for two blends. Effect of colloidal instability based on asphaltenes precipitation and SARA composition on fouling was also discussed.
Two dimensional numerical modeling of a silicon solar cell with selective emitter configuration (2010)

This paper reports the design of a two dimensional numerical model for silicon solar cells to study a selective emitter configuration. The solar cell model has an n <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> p p <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> structure with a measured doping profile in the emitter and uniformly doped back surface field. The carrier flow pattern in the solar cell was analyzed by solving the diffusion equations using appropriate boundary conditions. The numerical model was developed in COMSOL by solving the Poisson equation; the current density equation and the continuity equation in each region. This model uses Fermi Dirac statistics to determine carrier densities in heavily doped regions. The simulation results indicate that if the surface doping density under the selective emitter is very high compared to the field (non-selective) region, then the width of the selective emitter fingers strongly influences V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">oc</sub> . But if the surface doping density under the selective emitter is only slightly high compared to the field region, then the influence on V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">oc</sub> is modest. This model can be used as a tool for understanding and optimizing the selective emitter configuration in the emitter region. Solar cells were fabricated with selective emitter configurations with various doping densities. Validation of the 2D model was done by comparing the simulation results with experimental results.
O008/#283 Combination therapy with topotecan, paclitaxel, and bevacizumab improves progression-free survival in patients with recurrent high-grade neuroendocrine carcinoma of the cervix: a nectur study (2022)

<h3>Objectives</h3> The objective of this study was to evaluate the efficacy of the three-drug regimen topotecan, paclitaxel, and bevacizumab (TPB) in women with recurrent high-grade neuroendocrine cervical cancer (HGNECC). <h3>Methods</h3> This retrospective cohort study used data from the Neuroendocrine Cervical Tumor Registry (NeCTuR). The study compared women with recurrent HGNECC who received TPB as first- or second-line therapy for recurrence and women with recurrent HGNECC who received chemotherapy but not TPB. Progression-free survival from the start of treatment for recurrence to the next recurrence or death, overall survival from first recurrence, and response rates were evaluated. <h3>Results</h3> The study included 57 patients who received TPB as first- or second-line treatment for recurrence and 48 patients who received chemotherapy but not TPB for recurrence. Median progression-free survival was 8.2 months in the TPBgroup compared to 3.1 months in the non-TPBgroup, with a hazard ratio for progression of 0.23 (95% CI 0.14–0.40; P &lt; 0.0001). In the TPB group, 16% had stable disease, 38% had a partial response, and 16% had a complete response. Significantly more patients in the TPB group than in the non-TPB group remained on treatment at 6 months (67% vs. 25%, P = 0.0002) and 1 year (24% vs. 6%, P = 0.03). Median overall survival was 16.9 months in the TPBgroup compared to 14.0 months in the non-TPB group, with a hazard ratio for death of 0.89 (95% CI 0.55–1.45). <h3>Conclusions</h3> TPB is an active regimen in women with recurrent HGNECC and improves progression-free survival while decreasing the hazard ratio for progression.
1H NMR assignment corrections and 1H, 13C, 15N NMR coordination shifts structural correlations in Fe(II), Ru(II) and Os(II) cationic complexes with 2,2′‐bipyridine and 1,10‐phenanthroline (2010)

(1)H, (13)C and (15)N NMR studies of iron(II), ruthenium(II) and osmium(II) tris-chelated cationic complexes with 2,2'-bipyridine and 1,10-phenanthroline of the general formula [M(LL)(3)](2+) (M = Fe, Ru, Os; LL = bpy, phen) were performed. Inconsistent literature (1)H signal assignments were corrected. Significant shielding of nitrogen-adjacent protons [H(6) in bpy, H(2) in phen] and metal-bonded nitrogens was observed, being enhanced in the series Ru(II) --> Os(II) --> Fe(II) for (1)H, Fe(II) --> Ru(II) --> Os(II) for (15)N and bpy --> phen for both nuclei. The carbons are deshielded, the effect increasing in the order Ru(II) --> Os(II) --> Fe(II).
