Sperm-associated oocyte-activating factor is released from the spermatozoon within 30 minutes after injection as a result of the sperm- oocyte interaction (1997)

We have previously shown that sperm plasma membrane damage makes the sperm plasma membrane permeable and the sperm nucleus accessible for low molecular weight molecules such as eosin and dithiothreitol. In the present study, we investigated whether this damage is associated with a passive release of the sperm-associated oocyte activating factor (SAOAF) from the spermatozoon and, if so, its time sequence. In a first study, human oocytes remaining unfertilized after conventional in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) and freshly ovulated mouse oocytes were injected with a whole spermatozoon or a sperm head respectively. They were randomly allocated to one of three groups: oocytes in group 1 were injected with a spermatozoon immobilized or sperm head detached immediately prior to the injection; oocytes in group 2 were injected with a spermatozoon immobilized or sperm head detached 2-4 h before injection; oocytes in group 3 were injected with a spermatozoon or sperm head that had been subjected to heat treatment. The activation rate of oocytes injected with a spermatozoon or sperm head was the same for groups 1 and 2, and significantly higher than in group 3 (P < 0.001). In a second series of experiments, human oocytes remaining unfertilized after IVF or ICSI were injected with a sperm head that was subsequently removed from the ooplasm 20-30 min after injection. The activation rates were compared to that of oocytes injected with heat-treated spermatozoa which subsequently were removed from the ooplasm. We found that the removal of the spermatozoon 30 min after injection did not prevent oocyte activation. Our data indicate that the initial damage to the sperm plasma membrane induced at immobilization, although essential for the onset of sperm nuclear swelling after ICSI, does not by itself lead to the release of SAOAF from the spermatozoon. We postulate, however, that SAOAF is released during the sperm nuclear swelling phase, which is induced by the so-called sperm nucleus decondensing factor (SNDF) of the oocyte.
Definition of an Optimal Cytotoxic T Lymphocyte Epitope in the Latently Expressed Kaposi's Sarcoma–Associated Herpesvirus Kaposin Protein (2001)

Cytotoxic T lymphocytes (CTL) recognize and kill virus-infected cells and contribute to immunologic control of viral replication. For many herpesviruses (e.g., Epstein-Barr and cytomegalovirus), virus-specific CTL responses can be readily detected in infected persons, but CTL responses against Kaposi's sarcoma-associated herpesvirus (KSHV) appear to be weak and remain poorly characterized. Using a human leukocyte antigen (HLA) binding motif-based epitope prediction algorithm, we identified 37 HLA-A*0201 binding peptides from 8 KSHV open-reading frames (ORFs). After in vitro stimulation of peripheral blood mononuclear cells from KSHV-infected persons, CTL responses against 1 peptide in the KSHV kaposin protein (ORF K12) were detected in 2 HLA-A*0201-positive subjects. The optimal CTL epitope was identified by HLA restriction analysis and peptide titration assays. These data describe a latent phase viral gene product targeted by CTL that may be relevant for KSHV immunopathogenesis.
Expectation and SAA Models and Algorithms for Scheduling of Multiple Earth Observation Satellites Under the Impact of Clouds (2020)

In the explosively increased number of applications of earth observation satellites (EOSs), scheduling is a significative issue to satisfy more requests and obtain a high observation efficiency. This article investigates the scheduling of multiple EOSs under the impact of clouds. First, we formulate the presences of clouds as stochastic events, and propose an expectation model. Afterwards, for the first time, a branch-and-price algorithm based on Dantzig-Wolfe decomposition is devised to solve the model optimally and efficiently. In order to obtain initial columns for column generation, a dynamic programming algorithm and a heuristic algorithm are suggested, respectively. Furthermore, we discuss the impact of clouds in the case of joint probabilities, and establish a sample average approximation (SAA) model accordingly. With respect to the expectation model, numerical experiment results demonstrate the relative dominance of the proposed branch-and-price algorithm in terms of solution time compared to CPLEX. In addition, the solution of the proposed SAA model is proven to be more robust than that of the expectation model.
Application of Relative Permeability Modifiers to Control Water Cut Following Hydraulic Fracturing in Western Siberia Oilfields—Russian Case History Study (2006)

Abstract Due to geological characteristics and low permeability of Western Siberia hydrocarbon reservoirs, hydraulic fracturing is the most effective method for improving hydrocarbon production. During recent years the massive fracturing treatments in this area have led to a reduction of well candidates for this type of production enhancement technique. Currently the majority of selected wells for fracture stimulation are considered "risky" because of significant water cut increase after stimulation. The question arises - How to reduce water production while enhancing oil production? This paper reviews 26 case histories exemplifying the use of Relatively Permeability Modifiers (RPM) in hydraulic fracturing to enhance oil recovery and control water production. Also results of laboratory studies are included to support the RPM-fracturing concept and placement techniques.
Full Automatic sorting lithium health detection means (2020)

In today's era where lithium batteries are the main energy storage, a fully automatic lithium battery health status sorting device is designed for better, more standardized and faster sorting and recycling of waste lithium batteries. The system includes lithium battery transport unit and sorting mechanism; the hardware part is composed of main control module, motion control module, lithium battery health detection module and human-computer interaction module. STM32F1C8T6 is used as the main control module; the software uses MATLAB to fit the lithium battery resistance and lithium battery health status SOH, and quickly sort the battery health status according to the fit curve. The test results show that the automatic lithium battery health sorting device can quickly detect the lithium battery health status and sort the lithium battery according to the actual situation by manually inputting the battery model, sorting specification and battery number after a certain level of training. The system has a clear structure, with the benefits of accurate and fast health status detection and rapid lithium battery sorting.
Cranberry Juice Composition (1986)

Abstract Eight samples of cranberries (Vaccinium macrocarpon) representing the major varieties and principal commercial growing regions in the United States were processed into juice. Four of the 8 samples were concentrated to 50° Brix. Liquid chromatography (LC) was used to determine nonvolatile organic acid, anthocyanidin pigment, and sugar profiles. Ultraviolet-visible spectral methods were used to determine anthocyanin concentration, polymeric color, and percent polymeric color. Other data presented include stable isotope carbon ratios, degree Brix, pH, and Hunter color parameters. These data are presented to serve as an authentic data base for use in detection of adulterated cranberry juice.
Characterization, Compositional Studies, Antioxidant and Antibacterial Activities of Seeds of Abutilon indicum and Abutilon muticum Grown Wild in Pakistan (2009)

The Physicochemical properties, macro and micro elements (Al, Cd, Ca,Fe, Pb, Mg, P, K, and Zn), fatty acids, total phenolic content, antioxidant and antibacterial activities of oil from seeds of two Abutilon species, grown wild in Pakistan were investigated. Abutilon indicum L. (Malvaceae) and Abutilon muticum DC. (Malvaceae) were found to contain 5.9 and 6.3% moisture, 25.1 and 28.3% crude fiber, 22.4 and 23.5% crude protein, 2.3 and 3.4% ash and 33.1 and 25.6% carbohydrate respectively. Seed total lipids were extracted, characterized by chromatographic techniques and analyzed by mass spectrometry. The oils were found to be rich in neutral lipids (95.2 and 94.7% of total lipids) and low in polar lipids (3.7 and 3.6% of total lipids) for A. indicum and A. muticum respectively. GC-MS data showed that the main fatty acid was linoleic acid in both the species. Total phenolic compounds in each sample were determined according to Follin-Ciocalteu’s method as, 13.770 and 38.815 mg/g of oil, respectively. Total antioxidant activity of both oils was checked by ABTS, FRAP, DPPH and oleic acid peroxidation methods. These methods indicated the presence of both the slow reacting and fast reacting components in the seed oils of both the herbs. The seed oil of Abutilon indicum and Abutilon muticum showed broad spectrum activity as they were active against Gram-positive and Gram-negative bacteria. The findings reveal seeds of Abutilon species, indigenous to Pakistan to be potentially valuable herb for oil production, delivery of drugs and cosmetic active ingredients.
Fluorene‐Based Oligomers for Highly Efficient and Stable Organic Blue‐Light‐Emitting Diodes (2009)

Highly efficient and stable blue-light-emitting materials consisting of oligofluorenyl blocks and charge transporting segments are synthesized. The external quantum efficiencies of the solution-processed light-emitting diodes were of up to 6.1% and 8.6% for undoped and doped devices, respectively. The exceedingly high efficiency and excellent stability of these devices suggest that these new developed materials are very promising for deep-blue-light OLEDs.
Selected recombinant <i>Aspergillus fumigatus</i> allergens bind specifically to IgE in ABPA (2000)

The results demonstrate that Asp f 2, f 4, and f 6 can be used in the serodiagnosis of ABPA, while IgE antibody binding to Asp f 1 and f 3 was not specific.
Intraosseous Infusion of Hypertonic Glucose and Dopamine (1988)

Intraosseous infusion of drugs for resuscitation and of fluids has been advocated as an alternate emergency technique to intravenous infusion. The reliability of intraosseous infusion of many substances has not been established. Glucose and dopamine hydrochloride are two commonly used emergency drugs in pediatric practice that have not been carefully studied when administered into the bone marrow. In an animal model, we compared the response of an intraosseous injection of hypertonic glucose with that of an intravenous injection of hypertonic glucose. Serum glucose measurements following the injection revealed both routes of administration to be effective. A dopamine infusion was then administered through the bone marrow for 20 minutes. A statistically significant rise in blood pressure was observed two minutes after initiation of the infusion. Intraosseous infusion of hypertonic glucose and dopamine is an effective route by which to administer these medications and is potentially useful in emergency situations in which intravascular access is delayed.
터치스크린 GUI의 효과적인 표현에 관한 연구 - 터치스크린 기반의 모바일 폰 메인 화면 디자인을 중심으로 - (2009)

디지털 사회가 발전함에 따라 점차 표현 할 수 있는 미디어의 기능과 그에 따른 환경, 기술이 급속도로 변화하고 있다. 커다란 핸드폰에 단색의 스크린으로 겨우 문자정도나 구분 할 수 있었던 시절에서 지금은 텍스트에서부터 이미지는 물론 애니메이션과 플래시, 3D 게임까지 눈이 부시도록 빠르게 성장하였다. 현재는 터치스크린(Touch Screen)을 기반으로 한 모바일 폰이 등장했고 심미적인 측면과 기술적인 측면에서 GUI가 중요하게 부각되고 있다. 이런 터치스크린 기반의 모바일 폰 GUI는 단지 유저에게 향상된 기술력의 결과물로써가 아닌 기존 아날로그의 감성을 표현함으로써 그 주목도가 점점 상승되고 있다. 하지만 이런 발전이 장점만 존재하지는 않는다. 환경과 표현방식이 달라짐에 따른 단점과 약점들은 GUI를 개발하는 디자이너들의 과제로 남게 되었다. 디자이너들은 작은 모바일 스크린 속에 더 많은 정보와 기술들을 간단하고 편리하게 보여줄 수 있도록 끊임없는 연구와 노력을 하고 있는데, 이에 우리는 이 논문을 통하여 디자이너가 GUI에서 표현해야할 요소들을 유저들의 설문을 통해 논리적으로 추출하여 추후 터치스크린 기반의 모바일 폰에 대한 메인 화면 GUI의 방식과 나아갈 방향을 제시하고, 디자이너들의 고민을 덜어 주고자 한다.
Introduction: Decolonizing domestic service: introducing a new agenda (2015)

What is the relationship between domestic service and colonization, historically and into the present? How does domestic service connect and intersect with the experiences of dispossession, displacement and expropriation, and the social and cultural upheavals that such processes generate? This collection of essays represents a concerted effort to map out the ongoing significance of colonization for shaping the patterns of domestic service. It is an undertaking that seems timely now. We have witnessed a resurgence in domestic labor on a global scale in recent years, only growing in strength and intensity, that has produced an explosion of literature reflecting on domestic work. The triumvirate of race, class and gender categories of analysis has fundamentally reoriented perspectives within multiple disciplines in the last three or four decades. Scholars now routinely acknowledge and address the significance of the lives of women, working people and people of color (domestic workers often belonging to all three categories), as well as recognizing the importance of structural relations these categories entail, in themselves and in combination. Add to this the vibrant dynamic of postcolonial or 'new imperial' studies, attending to the domestic and the intimate as sites of power in colonial, postcolonial and neocolonial projects, and we have all the ingredients for a new way of approaching domestic service.
Novosphingobium pentaromativorans sp. nov., a high-molecular-mass polycyclic aromatic hydrocarbon-degrading bacterium isolated from estuarine sediment (2004)

A Gram-negative, yellow-pigmented, halophilic bacterial strain US6-1T, which degrades high-molecular-mass polycyclic aromatic hydrocarbons of two to five rings, was isolated from muddy sediment of Ulsan Bay, Republic of Korea. The 16S rRNA gene of the isolate showed high sequence similarity to Novosphingobium subarcticum (96.23 %) and Sphingopyxis alaskensis (96.18 %); however, the isolate formed a distinct phyletic line within the genus Novosphingobium. DNA-DNA relatedness between US6-1T and the closest strain N. subarcticum revealed that strain US6-1T was independent from this species. Isolate US6-1T had ubiquinone 10 and a DNA G + C ratio of 61.1 mol%. Major fatty acids were octadecanoic acid (18 : 1omega7), hexadecanoic acid (16 : 1omega7) and 2-hydroxy-myristic acid (14 : 0 2-OH). On the basis of polyphasic taxonomic evidence, strain US6-1T is proposed to represent a novel species in the genus Novosphingobium for which the name Novosphingobium pentaromativorans sp. nov. is proposed. The type strain is US6-1T (= KCTC 10454T = JCM 12182T).
A Structurally Durable EHC for the Exhaust Manifold (1994)

<div class="htmlview paragraph">It is well known that an EHC (Electrically Heated Catalyst) is very effective in reducing cold start HC emissions. However, the large electric power consumption of the EHC is a major technical issue. When installed in the exhaust manifold, the EHC can take advantage of exhaust heat to warm up faster, resulting in a reduced electric power demand. Therefore, a structurally durable EHC which can withstand the severe manifold conditions is desirable.</div> <div class="htmlview paragraph">Through the use of a extruded monolithic metal substrate, with a flexible hexagonal cell structure and a special canning method, we have succeeded in developing a structurally durable EHC.</div> <div class="htmlview paragraph">This new EHC installed in the exhaust manifold with a light-off catalyst directly behind it demonstrated a drastic reduction in FTP (Federal Test Procedure) Total HC emissions. Even after severe engine aging equivalent to 50,000 miles (850 °C x 100 Hours with a fuel cut mode), emissions continued to be reduced by more than 50 %, with less than 2kw of post heat, when tested in a 2 liter engine car.</div> <div class="htmlview paragraph">This low wattage and durable EHC can be a practical solution to meet LEV/ULEV regulations.</div>
Affinity labelling of the allosteric site of the L-lactate dehydrogenase of Lactobacillus casei (1983)

Kinetic investigations employing the substrate analogues 2-oxoglutarate and phospho(enol)pyruvate indicate that the allosteric L-lactate dehydrogenase (EC 1.1.1.27) of Lactobacillus casei has a non-catalytic pyruvate-binding site to which, in addition to pyruvate, the allosteric effector fructose 1,6-bisphosphate can also be found. A modification using the 14C-labelled substrate analogue 3-bromopyruvate induces a loss of regulation by fructose 1,6-bisphosphate. The histidine residue labelled by 3-bromopyruvate is homologous to histidine-188 which is part of the anion-binding site of the non-allosteric vertebrate L-lactate dehydrogenases. Thus, the allosteric site of the allosteric L-lactate dehydrogenases corresponds to the anion-binding site of the non-allosteric vertebrate enzymes.
Coupled metallic antenna nanorod arrays (2007)

We investigate coupling effects in arrays of gold nanorods, studying both strongly and weakly coupled regimes, with the ultimate goal of incorporating these arrays onto a compact fiber device.
The PRISM System: A Key to Organizational Effectiveness at Federal Express Corporation (1992)

This paper examines a new type of information system rarely described in the MIS literature, probably because very few such systems exist today. The system, which we have labelled as an organizational effectiveness system (OES), is designed to ensure the health and well-being of an organization in an increasingly complex and turbulent world. Its purpose and net effect are to allow the organization to be flexible and responsive. PRISM, a system developed at Federal Express Corporation, is an imitable example of such a system. As an advanced multi-technology system, it includes core personnel functions, expanded personnel and organizational functions, and extensive external interface features. The PRISM system permits significant and constant interactions with all managers and all employees. This paper describes PRISM in considerable detail, as well as its impact and benefits. By extrapolating from the Federal Express experience, critical success factors are derived for the development and implementation of organizational effectiveness systems in other organizations.
Neurofuzzy networks applied to settlement of shallow foundations on granular soils (2003)

In recent years, artificial neural networks (ANNs) have been applied successfully to many as- pects of geotechnical engineering and its related fields. In the majority of these applications, multi-layer per- ceptrons (MLPs) that are trained with the back-propagation algorithm are used. This can be attributed to the fact that MLPs trained with back-propagation have a high capability of data mapping. However, one short- coming of this type of ANN is that knowledge acquired during training is stored in the connection weights in a complex manner that is often difficult to interpret. Consequently, the rules governing the relationships be- tween the network input/output variables are difficult to quantify, and thus ANNs are often criticized for be- ing black boxes. One way to overcome this problem is to use neurofuzzy networks. Neurofuzzy networks combine the explicit knowledge representation of fuzzy systems with the potential power of ANN learning algorithms. Neurofuzzy networks can be trained by processing data samples to perform input/output map- pings, similar to the way MLPs do, with the additional benefit of being able to translate the acquired knowl- edge into a set of transparent fuzzy rules that clearly describe the model input/output relationships. A review of the literature indicates that neurofuzzy networks are new tools in the field of geotechnical engineering. In this paper, the feasibility of using neurofuzzy networks in the field of geotechnical engineering is investigated for a case study of predicting settlement of shallow foundations on granular soils. The type of neurofuzzy network that is used in this work is a B-spline network, which uses the adaptive spline modeling of observa- tion data (ASMOD) algorithm to automatically optimize the model structure and the number of model inputs. The results indicate that neurofuzzy networks are a useful technique that are: (i) capable of accurately pre- dicting the settlement of shallow foundations on granular soils, and (ii) able to provide a transparent under- standing of the relationship between settlement and the factors affecting it.
Bubble generation by microwaves: Analytical (1984)

Our previous numerical simulation of the response of a magnetic bubble film to strong localized microwave fields revealed a susceptibility instability at high microwave powers. For a circularly-polarized excitation, this instability can ultimately lead to the reversal of the magnetization (i.e., bubble generation). We introduce here an analytical derivation of the instability region and compare this with the flipover conditions obtained by numerical simulation. The calculation of the natural response of the system to small deviations from the steady state in the absence of damping yields three poles, all located on the imaginary axis of the complex frequency plane. In the presence of finite damping, if rf excitation conditions are appropriate, these poles will move into the right (unstable solution) half of the s plane. The frequency and magnitude of excitation necessary for instability are independent of the Gilbert damping parameter α provided α≪1.
Average-current-mode control of two-input buck postregulators used in power-factor correctors (1999)

The use of the average-current-mode control in the two-input buck postregulator is studied in this paper. Using this type of control, the attenuation of the input voltage ripple (100-120 Hz) increases in relation to the one obtained when a conventional voltage-mode control (with or without feedforward) is used and, therefore, lower bulk capacitors can be used to obtain a very low voltage ripple at the output, which is very important when a battery is connected at the output. This is very common in distributed power supply systems.
An integrated neurocomputing system (2002)

The design of a comprehensive neurocomputing system is discussed. This system comprises two distinct neural network environments: programming and execution. The programming environment is Pygmalion. An execution environment is proposed that extends Pygmalion by providing a range of target hardware, from conventional machines to parallel neurocomputers and specialized chips generated by silicon compilation. The authors present their view of the neurocomputing system in three stages. First, they describe the Pygmalion programming environment, then the integrated system, and finally the neurocomputer architecture. They discuss the design of neural chips for the neurocomputer, introducing their basic architectures and presenting the system's silicon compiler.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Current Understanding of the Circadian Clock and the Clinical Implications for Neurological Disorders (2001)

The changes in behavior that occur on a 24-hour basis to match the 24-hour changes in the physical environment due to the rotation of the earth on its axis are a hallmark of life on the planet Earth. The nervous system of both lower and higher organisms has evolved over millions of years to meet the demands of the dramatic changes in the physical environment that occur in relation to the changes in the light-dark cycle, optimizing the survival and reproductive success of the organism. During the past 50 years, it has been clearly established that the 24-hour nature of life was not simply a response to the 24-hour changes in the physical environment imposed by celestial mechanics, but instead was due to an internal time-keeping system in the brain. Many neurological disorders are associated with abnormal 24-hour rhythms, including the sleep-wake cycle. The recent discovery of the molecular basis of the neural clock in animals offers neurologists new avenues for studying the pathophysiology of neurological disorders.
