RIVER BANK FILTRATION FOR WASTEWATER REUSE IN IRRIGATION: ADAPTATION TO CLIMATE CHANGE (2022)

In the context of adaptation of the water resources sector to climate change, water reuse is widely proposed and encouraged especially in arid and semi-arid areas like the Middle East. We consider riverbank filtration (RBF) an appropriate technology that efficiently and dependably procure quality water from Zarqa River thus making a contribution to protect Jordan�s remaining surface and ground water resources. The river is contaminated with treated domestic and industrial wastewater principally from the city of Amman, but still serves as a main source for irrigation water. Since 2007, a riverbank filtration (RBF) well field consisting of six wells was installed along the Zarqa river, Jordan. Salt tracers were released to the hyporheic zone and were detected in a RBF well (5 m distance from the river) during subsequent pumping. From the tracer test data (pumping rate: 10 m3/h), rapid travel times were approximated (14 m/min). Additional sampling demonstrated that fecal indicator bacteria and bacteriophages were removed from river water by RBF at the Zarqa River field site by up to 4.2 log10, which is a significant improvement of the river water quality. This implies that public health risks from exposure to riverbank filtrated water, like consumption of raw vegetables that are irrigated with this water, may be reduced by 2000 to 2500 times as compared to using river water directly. These results suggest that riverbank filtration is an appropriate technology which can enhance the safe reuse of treated wastewater.

A giant chip multigate transistor ROM circuit design (1986)

Defect-tolerant techniques based on memory-cell duplication with address dispersion, fail-safe operation, and defect-tolerable combination decoding were developed to improve the fabrication yield of a large-chip-size mask-programmable read-only memory (ROM). These techniques have features of automatic inspection, detection, and selection. A multigate transistor ROM (MUGROM) cell and a high-sensitivity charge-transfer sense amplifier appropriate to this MUGROM have been developed which achieve high packing density and low power dissipation. Using these techniques and n-well CMOS technology, a 4-Mb ROM with an internal I/O port on a 34/spl times/21-mm/SUP 2/ size chip has been realized. It enables the ROM to be connected to the microprocessor data bus without peripheral interface LSI. The I/O port was designed to have two READ modes: a block data access mode for reading continuous data up to 1-kbit with fast cycle time, and a random access mode. Operating under a 1-MHz block data READ cycle, the device has a typical power dissipation of 20 mW with an access time of 7 /spl mu/s.
Enantiomerically Enriched Tetrahydropyridine Allyl Chlorides (2019)

Enantiomerically enriched allyl halides are rare due to their configurational lability. Here we report stable piperidine-based allyl chloride enantiomers. These allyl chlorides can be produced via resolution, and undergo highly enantiospecific catalyst-free substitution reactions with C, N, O and S-based nucleophiles. Deuterium-labelled chloro-tetrahydropyridine, selectively prepared using the H/D primary kinetic isotope effect, and DFT calculations were used to investigate the mechanisms of the reactions. The allyl chlorides may also serve as valuable mechanistic tools for probing stereoselective reaction pathways.

Arm-Leg Blood Pressure Gradient in Clinic to Predict Arch Hemodynamics and Ventricular Size after Coarctation Repair (2020)

Objective: Patients with successfully repaired coarctation of the aorta (CoA) need continued follow-up due to risks of restenosis and abnormal arterial compliance, causing early onset hypertension/coronary artery disease. We hypothesize that subtle hemodynamic and structural abnormalities can be predicted in the clinic by an abnormal arm-leg blood pressure (BP) gradient (i.e. arm &gt; leg systolic BP). Design: Uncomplicated CoA patients repaired between 1990 and 2007 with follow-up clinic visits documenting right arm and leg systolic BPs, along with a recent echocardiogram, were studied. Data included the Doppler peak instantaneous (PeakV) and mean velocities (MeanV) in the descending aorta along with measures of the proximal transverse arch (TA) diameter and left ventricular wall (LVPWd) thickness. Measurements were indexed by Z-scores. Patients were grouped by higher systolic BP in the leg (Group 1) or arm (Group 2). Results: Eighty-one patients met the criteria with 52 in Group 1 (median 12.5 years follow-up) and 29 in Group 2 (median 12 years follow-up). Group 2 group had significantly increased arm systolic BP Z-scores (p &lt;0.01), PeakV (p &lt;10-4 ), MeanV (p &lt;10-6 ), and LVPWd (p &lt;0.01) compared to Group 1. There was no difference, however, in arm diastolic BP (p =0.7) or TA diameter (p =0.5). These relationships held true even in otherwise “silent” patients without clinical hypertension. Conclusion: Abnormal arm-leg blood pressure gradients accurately identified CoA patients with elevated arch velocities and increased ventricular wall thickness years after repair. The arm-leg pressure measurements could more accurately select patients in need of further imaging studies and therapeutic interventions.
A novel calix[6]arene-based mononuclear copper(I) complex that exhibits chirality at low temperature (1998)

A calix[6]arene functionalized in alternate positions at the lower rim with three picolyl groups acts as a biomimetic N3 ligand with cuprous ion. The stable C3 symmetrical complex derived from CuCl exists as a pair of helical enantiomers. A low temperature 1H NMR study revealed that the chirality is transmitted to the calixarene skeleton, thereby providing a chiral cavity around the apical binding site of the metal center.
Nucleation of Nickel Disilicide Precipitates in Float‐Zone Silicon: The Role of Vacancies (2022)

Nickel Disilicide Precipitates Nickel is an important metal impurity in float-zone silicon and has to be controlled tightly in device production. Its precipitation into NiSi2 particles is well understood except for the initial stages. It is shown that substitutional nickel species, whose concentration are steered by excess vacancies stored in nitrogen-vacancy complexes, serve as nucleation sites, which is explained by a microscopic model in article number 2200220 by Michael Seibt and co-workers, published as part of the GADEST 2022 Special Issue.

Birefringence in rapidly rotating glass disks (1998)

Centripetal forces modify the optical properties of a rotating glass disk, thus creating a circularly symmetric distortion in the refractive index. This centripetal birefringence has a strong radial dependency and increases with the square of the spin speed. The effect on a polarized beam transmitted through the glass may be reduced mathematically to that of an effective wave plate whose retardance and orientation may be calculated from knowledge of the stress distribution in the disk. Alternatively, one can directly measure the Jones-matrix elements that correspond to the effective wave plate by use of polarization phase measurements at two or more locations on the disk. This direct measurement compensates the centripetal birefringence in the instrumentation employed by the data-storage industry to measure the flying height of read–write heads.
Ethylene-Propylene-Diene Terpolymer/Polyacetylene and Styrene-Diene Triblock Copolymer/Polyacetylene Blends (1984)

Two different blends, EPDM/polyacetylene and Kraton/polyacetylene have been prepared by various blending techniques. The characterization of two blends have been carried out by IR, X-ray and electron microscopic studies. Upon doping of the blends with various electron accepting agents, such as I2 and FeCl3, conductivities of the blends were found to be in the range of 10 - 100Ω-1cm-1. The conductivity stabilities of the blends have also been studied.
In-vitro secretion of proinflammatory cytokines by human amniochorion carrying hyper-responsive gene polymorphisms of tumour necrosis factor- and interleukin-1 (2003)

The identification of polymorphisms in genes encoding proinflammatory cytokines that affect transcription or the secretion rate has opened new ways to understand the variation in responses to infection during pregnancy. In this study, human amniochorion carrying hyper-responsive alleles of tumour necrosis factor-alpha (TNF-alpha: TNF*2 at -308) and interleukin-1beta (IL-1beta: IL-1*2 at +3953) were stimulated in vitro with bacterial lipopolysaccharide (LPS) and compared with tissues carrying the common alleles (TNF*1 and IL-1*1). Fetal membranes carrying the TNF*1 allele displayed an identical dose-response pattern to tissues carrying a TNF*2 allele, except at the highest dose of LPS tested (50 ng/ml) there was a significantly greater production of TNF-alpha in the presence of a TNF*2 allele. Membranes carrying the IL-1*2 polymorphism secreted IL-1beta in a dose-response curve that was different from IL-1* tissues when challenged with 5, 10 and 50 ng/ml LPS. These observations support the hypothesis that reproductive tissues carrying hyper-responsive proinflammatory cytokine genes may over-respond to intrauterine infection secreting higher amounts of cytokines, which in turn, may lead to adverse pregnancy outcomes.
Improvement of nitrogen retained dose using ammonia as a precursor in nitrogen plasma immersion ion implantation of silicon (2005)

The low nitrogen retained dose due to competition from oxygen coimplantation diminishes the efficacy of nitrogen plasma immersion ion implantation in silicon. In this work, we aim at improving the nitrogen retained dose by using ammonia as a precursor. Ammonia is introduced into the nitrogen plasma during plasma immersion ion implantation of silicon to improve the nitrogen reactivity and reduce the competition from oxygen in the residual vacuum. Our x-ray photoelectron spectroscopy and Fourier-transform infrared spectroscopy results indicate that the ammonia precursor can indeed improve the N retained dose effectively, and the hydrophilic properties of the surface change with different ammonia to nitrogen ratios.

Prefetching in an Intelligent Memory Architecture Using a Helper Thread (2001)

Data prefetching is a popular technique for tolerating long memory access latencies. In this paper, we introduce a novel type of prefetching: memory-side correlation prefetching implemented in a user-level thread. The prefetching thread runs on a general-purpose processor embedded in the main memory. By allocating the correlation table in main memory, we can afford the large space required by the table. In addition, the scheme can be supported with few modifications to the L2 cache and no modification to the main processor core. We introduce a new organization of the correlation table and a new prefetching algorithm that enable fast and accurate farahead prefetching with high coverage. Overall, our evaluation shows that the algorithm effectively prefetches irregular applications, speeding up three applications by an average of 1.28. Furthermore, our scheme can work synergistically with a conventional processor-side prefetcher to deliver an average speedup of 1.36. 1

Mechanical Properties of Sputter‐Deposited Titanium‐Silicon‐Carbon Films (2001)

The effect of SiC additions on the mechanical properties of TiC films was investigated. Ti‐Si‐C films with varying SiC content were deposited using dual‐cathode radio‐frequency magnetron sputtering. The nanoindentation hardness of these films increased with SiC content to a maximum of 20–22 GPa for films in the range of 15–30 at.% SiC. The elastic modulus was also measured, and the hardness to modulus ratio ( H / E ) increased with SiC content, indicating that hardness increases were due to microstructural effects. The residual stress was measured in several films, but was low in magnitude, indicating that hardness measurements were not influenced by residual stress. TEM examination of several films revealed that the SiC additions altered the film microstructure in a manner that could account for the observed hardness increases.
Cervical cancer in South Africa : challenges and opportunities (2013)

South Africa has a high burden of cervical cancer despite the existence of a national programme that focuses on this disease. The implementation of a national human papillomavirus (HPV) vaccination strategy that uses the service delivery platform of the integrated school health programme is an integral part of a comprehensive cervical cancer control policy for the country. There will be challenges in implementing such a programme. Lessons learned from the successful implementation of the HPV vaccine through national programmes and demonstration projects will guide all stakeholders in ensuring the efficient equitable and safe delivery of the vaccine to the target population. This chapter discusses the burden of disease from cervical cancer HPV vaccines the relevant national policies and the opportunities and challenges associated with the implementation of HPV vaccination. This content is a summary of information from sources considered pertinent to the implementation of the HPV vaccine and is not intended to be a systematic review.
Role of Wax Ester Synthase/Acyl Coenzyme A:Diacylglycerol Acyltransferase in Oleaginous Streptomyces sp. Strain G25 (2016)

A novel Streptomyces strain was isolated from desert soil, which represents an extreme environment with high temperatures, frequent drought, and nutrient scarcity. We believe that these harsh conditions promoted the development of the capacity for this strain to accumulate extraordinarily large amounts of lipids. In this study, we present the analysis of its draft genome sequence with a special focus on enzymes potentially involved in its lipid storage. Furthermore, the activity and importance of the detected acyltransferase were studied. As discussed in this paper, and in contrast to many other bacteria, streptomycetes seem to possess a complex metabolic network to synthesize lipids, whereof crucial steps are still largely unknown. This paper therefore provides insights into a range of topics, including extremophile bacteria, the physiology of lipid accumulation, and the biotechnological production of bacterial lipids.
Perturbation analysis of gas-surface diffractive selective adsorption resonance states (1989)

It is shown on the basis of infinite order perturbation theory that narrow resonances, which are obtained when the corrugation amplitude is sufficiently high, are not revealed by an effective one-dimensional potential surface, and it is not possible to derive an optimum adiabatic factorization which is independent of the distance from the surface.
Comment on “Reduced T-Dependent Humoral Immunity in CD20-Deficient Mice” (2013)

CD20 was the first B cell surface Ag identified as a regulator of B cell function in 1985 ([1][1]) and the anti-CD20 Ab rituximab was the first therapeutic Ab approved for the treatment of B cell neoplasia. Yet the precise functions of CD20 and its Abs are still controversial issues ([2][2]). The
Cutaneous Merkel cells of the rat contain both dynorphin A and vesicular monoamine transporter type 1 (VMAT1) immunoreactivity (1998)

To delineate fully opioid peptide function in cutaneous inflammatory and nociceptive responses, it is necessary to know first which opioid peptides are present in the skin and which cellular elements in the skin store and secrete them. Merkel cells are cutaneous neuroendocrine cells, which may derive from the neural crest or from undifferentiated keratinocytes with stem cell character. The neuroendocrine character of Merkel cells is supported by their immunoreactivity for chromogranin A (CGA) and a variety of neuropeptides, among them the opioid peptide [Met]enkephalin as shown in guinea-pig and mouse. This study investigates in the rat whether the preprodynorphin derived opioid peptide dynorphin A is expressed in cutaneous Merkel cells and possibly related to an aminergic phenotype. Light microscopic immunohistochemistry revealed dynorphin A immunoreactivity in Merkel cells to be codistributed with immunoreactivity for calcitonin gene-related peptide (CGRP) and CGA, two well-established merker peptides of mammalian Merkel cells. Vibrissal Merkel cells stained for the neuroendocrine vesicular monoamine transporter isoform 1 (VMAT1) but not for the predominantly neuronal isoform 2 (VMAT2). Merkel cell staining for dynorphin A, VMAT1, CGA, and CGRP was unaffected by experimental denervation. Dynorphin A and a still unidentified monoamine, possibly serotonin, may cofunction as autocrine or paracrine mediators in the mechanosensory Merkel cell--axon complex and are potentially involved in peripheral analgesia.

Lymphoma‐associated mutations in autoreactive memory B cells of patients with Sjögren's syndrome (2022)

We recently demonstrated that normal memory B lymphocytes carry a substantial number of de novo mutations in the genome. Here, we performed exome-wide somatic mutation analyses of bona fide autoreactive rheumatoid factor (RF)-expressing memory B cells retrieved from patients with Sjӧgren's syndrome (SS). The amount and repertoire of the de novo exome mutations of RF B cells were found to be essentially different from those detected in healthy donor memory B cells. In contrast to the mutation spectra of normal B cells, which appeared random and non-selected, the mutations of the RF B cells were greater in number and enriched for mutations in genes also found mutated in B-cell non-Hodgkin lymphomas. During the study, one of the SS patients developed a diffuse large B-cell lymphoma (DLBCL) out of an RF clone that was identified 2 years earlier in an inflamed salivary gland biopsy. The successive oncogenic events in the RF precursor clone and the DLBCL were assessed. In conclusion, our findings of enhanced and selected genomic damage in growth-regulating genes in RF memory B cells of SS patients together with the documented transformation of an RF-precursor clone into DLBCL provide unique novel insight into the earliest stages of B-cell derailment and lymphomagenesis. © 2022 The Authors.
