Anomalies in the US precipitation extremes and their association with different modes of climate variability

ABSTRACT In this study, we investigate the temporal oscillations of precipitation extremes in different climate regions of the United States. We apply quantile perturbation analysis to average daily precipitation and, to 1041 weather stations with high-quality data from 1900 to 2016. Moreover, we explore the relationship between the extreme precipitation and different well-known cyclical climate modes. Overall, the analysis of average daily precipitation identifies a drier condition in the middle decades of the twentieth century and, a wetter climate in the early century and recent decades. Moreover, the in situ analysis reveals a significant anomaly, mainly prevalent in the Central and Southern regions of the United States. We applied a finite set of linear regression models with different combinations of cyclical climate modes to inform the variability of anomalies with best performing models. Our results highlight the dominant effect of ENSO and NAO in the wide area of the United States.
Psychiatric Conditions Prevalent Among Adults With Down Syndrome

The authors assessed available prevalence information regarding neuropsychiatric conditions among adults with Down syndrome (DS) and compared these findings among adults with other intellectual disability (non-DS). The study entailed a survey of 291 adults with DS living in Ohio (USA). Twenty-three percent of adults with DS reported having a co-occurring psychiatric disorder, a smaller than the reported occurrence of such conditions in the general adult intellectual disability population. Depression, anxiety disorders, and dementia or Alzheimer's disease were the most frequently reported neuropsychiatric disorders by adults with DS. The likelihood of experiencing a psychiatric disorder increased with age but did not vary by sex among adults with DS. Lower rates of problem behavior were reported in adults with DS compared to adults with intellectual disability (non-DS). The authors' findings indicate that adults with DS may present different rates and types of co-occurring psychiatric disorders than the larger population of adults with other intellectual disability. These findings warrant additional research and could provide critical information for planning and intervention.

Physicochemical assessment of tailor made fibrous polyurethane scaffolds incorporated with turmeric oil for wound healing applications

Abstract Nanofibrous scaffold holds a great potential in remodeling of the damaged tissue. This work attempts to fabricate a fibrous wound dressing scaffold based on polyurethane (PU) mats reinforced with turmeric oil via electrospinning technique. The field emission electron microscopy (FESEM) depicted the smaller fiber diameter of nanocomposites compared to polyurethane. Fourier transform infrared spectroscopy (FTIR) and thermal analyses insinuated the existence of turmeric in the PU matrix by the formation of hydrogen bond and reduced weight loss for composite scaffold. Contact angle of the PU scaffold showed a hydrophobic behavior while turmeric oil incorporation resulted in the hydrophilic nature. Atomic force microscopy (AFM) analysis showed a decrease in surface roughness of PU with the addition of turmeric oil. In blood compatibility results, the coagulation times were observed to the higher for PU/turmeric oil than PU. The developed nanocomposites showed a less percentage of lysis of red blood cells suggesting better blood compatibility than PU. Further, cell viability assay depicted enhanced proliferation of fibroblast cells in the developed composites than PU. Overall, it was concluded that fabricated novel scaffold having better physicochemical and good biocompatibility characteristics for wound dressing.
Synergistic effects of halloysite and carbon nanotubes (HNTs + CNTs) on the mechanical properties of epoxy nanocomposites

The synergistic effects of halloysite nanotubes (HNTs) and carbon nanotubes (CNTs) on the mechanical properties of epoxy nanocomposites were investigated. The addition of hybrid nanofillers (0.5 wt% HNTs–0.5 wt% CNTs) has significantly increased the storage modulus, flexural strength, tensile strength, fracture toughness (K1C), critical strain energy release rate (G1C), and microhardness of the nanocomposites. The tensile strength and Young’s modulus increased up to approximately 45% and 49%, respectively. The flexural strength and modulus increased up to approximately 46% and 17%, respectively. K1C, G1C, and microhardness recorded improvements of up to approximately 125%, 134%, and 11%, respectively. The formation of a large number of microcracks (emanated radially) and the increase in fracture surface area (due to crack deflection) were the major toughening mechanisms in the hybrid nanocomposites. SEM images revealed that the hybrid nanofillers were uniformly dispersed in the epoxy matrix and the fracture surface was coarser than that of neat epoxy, suggesting a semi-ductile fracture. This study has shown that the synergistic effects of HNTs–CNTs hybrid nanocomposites at low content (0.5 wt% HNTs–0.5 wt% CNTs) have significantly enhanced the mechanical properties of epoxy nanocomposites.
Suppression of Delay-induced Instabilities of Digital Piezoelectric Vibration Absorbers

Abstract. Digital piezoelectric vibration absorbers synthesizing passive shunt circuits may be subject to instabilities. This work investigates the cause for these instabilities, and highlights the role of sampling delays in their onset. If for practical reasons the sampling frequency cannot be increased, a stabilization procedure which anticipates the sampling delays is proposed. The theoretical developments in this work are experimentally validated on a piezoelectric beam.

The aim of our study consisted in obtaining, phytochemical and antioxidant activity evaluation of two selective dry extracts from the leaves of Ficus elastica Roxb. ex Hornem and Raphanus sativus L. , with potential use in metabolic diseases. The results of the phytochemical assessment of the two hydroethanolic dry extracts (the employed hydroethanolic mixture were: 70% ethanol (v/v) for Fici elastici folium and 50% ethanol (v/v) for Raphani sativi folium) indicated the following: Fici elastici extractum (FEE) 3.6140±0.4000 g% flavonoids expressed as hyperoside, 5.950 ± 0.3800 g% phenolcarboxylic acids expressed as chlorogenic acid, 13.3299 ± 0.1583 g% total phenolic compounds expressed as tannic acid; 2. Raphani sativi extractum (RSE) 6.7300 ± 0.6600 g% flavonoid expressed as hyperoside, 3.1263 ± 0.1500 g% phenolcarboxylic acids expressed as chlorogenic acid, 21.4175 ± 0.9454 g% total phenolic compounds expressed as tannic acid. The HPLC analysis confirmed the presence of apigenin-7-glucoside in Raphani sativi extractum. Evaluation of the antiradicalar activity of the dry extracts was determined by scavenger activity of free radicals, 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2’-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS•+) and by ferric reducing power method. The antioxidant activity was expressed as EC50 mg/mL. The following results were obtained: EC50DPPH = 6.4166 ± 0.3329 mg/mL, EC50ABTS = 0.0768 ± 0.0020 mg/mL, EC50ferric reducing power = 0.4027 ± 0.0016 mg/mL (for FEE); EC50DPPH = 7.5100 ± 0.1414 mg/mL, EC50ABTS = 0.2611 ± 0.1893 mg/mL, EC50ferric reducing power =1.3935 ± 0.0111 mg/mL (for RSE).
Near-Infrared- and Magnetic-Field-Responsive NaYF4:Er3+/Yb3+@SiO2@AuNP@Fe3O4 Nanocomposites for Hyperthermia Applications Induced by Fluorescence Resonance Energy Transfer and Surface Plasmon Absorption

Monodispersed upconversion nanoparticles NaYF4:Er3+/Yb3+ (UCNPs) have been synthesized via the thermolysis method. Forster or fluorescence resonance energy transfer (FRET) dynamics from NaYF4:Er3+/Yb3+ (UCNPs) to gold nanoparticles (AuNPs) are well understood. However, only FRET-based heating (negligible heating from fluorophore or gold) is not much known so far in such systems under near-infrared (NIR) photon excitation. NIR-to-visible upconversion (UC) has already proven its utility in bioassays. Ultrasensitive FRET responsible surface plasmon resonance (SPR) induced hyperthermia has been estimated through water-dispersible monodispersed hybrid UCNP@SiO2@AuNPs via 980 nm NIR laser excitation. The trivial amount of heating for UCNPs and AuNPs are tested under continuous wave (CW) laser excitation. At ∼600 mW laser input power, a temperature increase to ∼43 °C has been noted within 15 min upon CW 980 nm laser excitation. The time-dependent magnetic field study performed with Fe3O4 and hybrid UCNP@SiO2@AuN.
Co-Crystal with Unusual High Z′ and Z′′ Values Derived from Hexamethylenetetramine and 4-fluorophenol (1/1)

The title co-crystal, 1,3,5,7-tetraazatricyclo[3.3. 1.13,7]decane (HMTA, 1)–4-fluorophenol (4-FP) (1/1), C6H12N4·C6H5FO, shows an unusual asymmetric unit that comprises eight independent molecules (Z′′ = 8), four for each component, with four formula units per asymmetric unit (Z′ = 4). In the molecular packing, each HMTA molecule bridges one 4-FP molecule via an O−H···N hydrogen bond to form a two-molecule aggregate. Differences can be observed between the bond lengths and angles of the independent HMTA and 4-FP molecules and those of the molecules in the aggregate. The C−N bonds exhibit different bond lengths in the tetrahedral cage-like structure of the HMTA molecules, but the largest differences between the molecular aggregates are in the bond lengths in the 4-fluorophenol ring. In the crystal, the HMTA and 4-FP molecules form two hydrogen-bonded (O−H···N, C−H···F and C−H···O) dimers of HMTA and 4-FP molecules, A···D and B···C inversion dimers, which generate enlarged R88(34) ring motifs in both supramolecular structures. In both structures, the crystal packing also features additional C−H···F and C−H···O interactions. The A···D and B···C dimers are linked by additional C−H···F and C−H···O hydrogen bonds, forming columns along the a and b axes, respectively. The importance of the C−H···F interaction to the structure and crystal packing has been demonstrated.
High molecular weight carboxymethyl cellulose binder to enhance integrity of silicon anodes for Li-ion batteries

Today, considerable interest for eco-friendly and renewable energy systems has been increased toward. Among sustainable energy systems, lithium-ion batteries have been treated as a promising energy device for high-energy batteries. Among anode materials, silicon has attracted attention as a promising candidate for high-energy LIBs due to its high theoretical capacity. However, electrochemical reactions of silicon materials normally result in electrode failure, which cause cell degradation due to massive volume changes upon cycling. To resolve problems, many researchers have studied outstanding binders, which are efficient to sustain the mechanical integrity of electrodes and electrical conductivity, leading to improved electrochemical performances. Herein, we discuss recent works and main issues for functional binders and provide binding mechanisms in terms of chemical and physical features. The relationship between chain lengths of CMC binders and enhanced electrochemical performances of silicon-graphite composite anodes is discussed in detail.

A High Count-Rate and Depth-of-Interaction Resolving Single-Layered One-Side Readout Pixelated Scintillator Crystal Array for PET Applications

Organ-specific, targeted field-of-view (FoV) positron emission tomography (PET)/magnetic resonance imaging (MRI) inserts are viable solutions for a number of imaging tasks where whole-body PET/MRI systems lack the necessary sensitivity and resolution. To meet the required PET detector performance of these systems, high count-rates and effective spatial resolutions on the order of a few mm, a novel two-axis patterned reflector foil pixelated scintillator crystal array design is developed and its proof-of-concept illustrated in-silico with the Monte Carlo radiation transport modeling toolkit Geant4. It is shown that the crystal surface roughness and phased open reflector cross-sectional patterns could be optimized to maximize either the PET radiation detector’s effective spatial resolution, or count rate before event pile up. In addition, it was illustrated that these two parameters had minimal impact on the energy and time resolution of the proposed PET radiation detector design. Finally, it is shown that a PET radiation detector with balance performance could be constructed using ground crystals and phased open reflector cross-sectional pattern corresponding to the middle of the tested range.
Are Pediatric Emergency Care Applied Research Network Rules (PECARN) Sufficient for Computed Cranial Tomography Decision in Pediatric Patients with Mild Head Trauma? Hafif Kafa Travmali Pediyatrik Hastalarda Bilgisayarli Beyin Tomografisi Karari İçin PECARN Kurallari Yeterli midir?

Objective: In this study we aimed to investigate the applicability of Pediatric Emergency Care Applied Research Network (PECARN) rules for decision to perform computed cranial tomography (CCT) in pediatric patients with minor head trauma (MHT). Methods: 317 pediatric patients who underwent CCT for mild head trauma were evaluated retrospectively. The patients were classified in two groups according to PECARN rules: below 2 years old, above 2 years old and then, these patient groups were classified into two subgroups accord ing to the compatibility with PECARN rules. The patients requiring CCT according to PECARN rules were classified as PECARN compatible (PECARN +), the patients who underwent CCT without the need of CCT according to PECARN were classified as PECARN incompatible (PECARN -). Results: Approximately 20% patients in PECARN (+) group had abnormalities leading to prolonged hospitalization and only 3.8% patients of PECARN (-) group had abnormalities. However, none of PECARN (-) group patients required follow-up longer than 48 hours in the hospital. The most common symptoms necessitate CCT in PECARN (+) group were scalp swelling, scalp hematoma and vomiting. In PECARN (-) group the most common signs were cuts in the scalp and dermal abrasions. The incidence of fracture in CCT was significantly higher in PECARN (+) group. Conclusion: Because CCT poses serious radiation exposure, neurological examination and clinical follow-up should be preferred in the evaluation of children with MHT. In conclusion, PECARN rules were sufficient for CCT decision in pediatric patients with MHT. J Clin Exp Invest 2016; 7 (1): 35-40
Carbonation Induced Corrosion in Reinforced Concrete Structures - A Review

: Carbonation a major reason for corrosion is one of the most critical problems that impair the durability of RC structures and is caused due to decrease in P H of concrete, relative humidity, temperature and carbon dioxide percentage. The cracking and spalling in concrete due to expanding corrosion products and the reduction in the cross-sectional area of rebar jeopardize the safety and serviceability of RC structures.
Mechanical Properties of Submicron Glass Fiber Reinforced Vinyl Ester Composite

Vinyl ester (VE) resin inherently has intrinsic brittleness due to its high cross-link density. To improve mechanical performance, micro/nano fillers are widely used to modify this matrix. In present study, glass fiber in submicron scale at low contents was added into VE to prepare submicron composite (sMC). The impact resistance of un-notched sMC degraded with the increase of sGF content while that of notched-sMC remained the unchanged. Flexural properties of sMCs also were the same with that of neat resin. The results of Dynamic mechanical analysis (DMA) test showed the slight increase of storage modulus and the decrease of tan delta value in the case of sMC compared to those of un-filled matrix. However, the Mode I fracture toughness of sMC improved up to 26% and 61% corresponding to 0.3 and 0.6 wt% glass fiber used. The compact tension sample test suggests that there is the delay of crack propagation under tensile cyclic load in resin reinforced by submicron glass fiber. The number of failure cycle enlarged proportionally with the increment of sGF content in matrix.
Molecular Dynamics Study on Transmission Mechanism of Torsional Deformation in Cellulose Nanofibers with Hierarchical Structure

Cellulose nanofiber (CNF) is a fibrous and nano-sized substance produced by decomposition of bulk-type cellulose which is a main component of plants. It has high strength comparable to steel, and it shows low environmental load during a cycle of production and disposal. Besides it has many excellent properties and functions such as high rigidity, light-weight, flexibility and shape memory effect, so it is expected as a next-generation new material. Usually it is composed of many cellulose micro fibrils (CMFs) in which molecular chains of cellulose are aggregated in a crystal structure, the knowledge of mechanical properties for each CMF unit is important. Since actual fibrils are complicatedly intertwined, it is also crucial to elucidate the transmission mechanism of force and deformation not only in one fibril but also in between fibrils. How the dynamic and hierarchical structure composed of CMFs responds to bending or torsion is an interesting issue. However, little is known on torsional characteristics (shear modulus, torsional rigidity, etc.) concerning CMF. In general, in a wire-like structure, it is difficult to enhance torsional rigidity and strength, compared with tensile ones. Therefore, in this study, we try to build a hierarchical model of CNF by multiplying CMF fibers and to conduct molecular dynamics simulation for torsional deformation, by using hybrid model between all-atom and united-atoms model. First, shear modulus was estimated for one CMF fibril and it showed a value close to the experimental values. Also, we assume a state in which two CMFs are ideally arranged in parallel, and create a hierarchical structure. We evaluate the dependence on the temperature for the bond strength and toughness in the hierarchical structures. Furthermore, we mentioned the transmission mechanism between components of a hierarchical structure.
Effects of an Infant-Focused Relationship-Based Hospital and Home Visiting Intervention on Reducing Symptoms of Postpartum Maternal Depression: A Pilot Study

Relationship-based interventions are an effective means for reducing postpartum depression (PPD), but few cost-effective tools that can be administered efficiently in medical and home settings are available or well-studied. This study examines the efficacy of the Newborn Behavioral Observations (NBO), an infant-centered relationship-based intervention, in reducing levels of postnatal maternal depression. First-time mothers and their infants were recruited in the postpartum units of 2 New England hospitals and randomized into intervention and control groups. A total of 106 mothers participated in this study. At 1 month postpartum, symptoms of PPD were assessed using the Edinburgh Postnatal Depression Scale (EPDS). Ten of the 106 mothers reported elevated levels of depressive symptoms (EPDS score >12), with 4% in the intervention group and 16% in the control group. Results indicated that the NBO was associated with lowering the odds of depressive symptomatology by approximately 75%. These findings suggest that the NBO conducted in hospital and home settings may be an efficient, cost-effective, relationship-based method for reducing the likelihood of PPD.
