Decay Spectroscopy of Neutron-rich 129 Cd with the GRIFFIN Spectrometer

Nuclei around doubly magic 132Sn are of particular interest in nuclear structure as well as nuclear astrophysics. Their properties provide important input for the r-process as waiting-point nuclei. For example, their shell structure and half-lives affect the shape of the second r-process abundance peak at A∼130. In terms of nuclear structure, the evolution of single-particle levels near shell closures is ideal for testing the current nuclear models far from stability. There have been two studies on the decay of 129Cd, however, the level schemes of 129In have large discrepancies. Also, many of the spins of the excited states remain unclear. Therefore, the main purpose of the present study is to resolve the disagreements in the reported level schemes and to determine the properties of the energy states. The experiment was performed at the ISAC facility of TRIUMF, Canada. A 480 MeV proton beam, which was accelerated by the main cyclotron at TRIUMF, was impinged on an uranium carbide target to produce radioactive isotopes. 129Cd was extracted using the Ion Guide Laser Ion Source (IG-LIS). γ-rays following the decays of 129Cd were detected with the GRIFFIN spectrometer comprising of 16 high-purity germanium (HPGe) clover type detectors, along with the β -particles detected with SCEPTAR. The high statistics and the high sensitivity of the detectors allowed us to perform detailed and precise spectroscopy. A theoretical calculation was conducted using the shell model code NuShellX @MSU, employing the realistic residual interaction model jj45pna. The results of the analysis, including 29 new transitions and 5 new excited states, will be discussed and compared to the theoretical calculations.
The effect of cow manure and cow rumen fluid on biogas production using Oscillatoria sp. biomass

In order to meet the growing demand for energy and to reduce the dependency on non-renewable energy sources, a renewable alternative energy source is needed. Oscillatoria sp. biomass has the potential to be processed into a renewable energy source because it can be produced continuously in sufficient quantities, environmentally friendly, and does not disrupt agricultural land. This study was conducted to identify the ability of microbes contained in cow manure and rumen fluid to produce biogas from Oscillatoria sp. biomass and optimize the concentration of these microbial sources. Cow manure and rumen fluid were utilized as a source of inoculum and the concentration was further optimized through central composite design (CCD) using a response surface methodological (RSM) approach. The results showed that cow manure had a more significant effect on biogas production compared to cow rumen fluid. In addition, fluctuations in pH values appear to affect biogas production activity. According to the model developed, the amount of optimum biogas produced was estimated can reach around 324 mL with the content of cow manure and rumen fluid are 128.03 mL and 21.97 mL respectively. The results of the validation experiments show that the cumulative biogas production reaches 350.33 mL or 8.12% more than the predicted biogas production from the regression model produced.
Tensile Strength Evaluation of Glulam Connection with Screw Fasteners

Multiple knife plate and external steel plate deep-beam glulam connections were investigated in a series of destructive tests within the Infrastructure Testing and Applied Research laboratory at Portland State University. The goal of these tests was to better understand the failure mode and ultimate load capacity of the large-scale glulam moment connections. Two different types of tests were performed on each connection; one with axial loading, and another loaded in flexure. The first, smaller, axial tests were conducted to inform the later, much larger, bending tests. The results of these tests helped to develop future designs as well as provide adequate proof of concept for an ongoing project. Each of the failure types were cataloged and the ultimate loads of each tested connection were compared to estimated design capacities. Block shear and shear type splitting were the most observed failure types. The results demonstrated the knife plate connection consistently failing before the expected load was reached, whereas the external steel plate connection regularly exceeding the expected loads.
A prospective analysis of 1518 laparoscopic cholecystectomies.

BACKGROUND AND METHODS The Southern Surgeons Club conducted a prospective study of 1518 patients who underwent laparoscopic cholecystectomy for treatment of gallbladder disease in order to evaluate the safety of this procedure. RESULTS Seven hundred fifty-eight operations (49.9 percent) were performed at academic hospitals, and 760 (50.1 percent) at private hospitals. In 72 patients (4.7 percent) the operation was converted to conventional open cholecystectomy; the most common reason for the change was the inability to identify the anatomy of the gallbladder as a result of inflammation in the region of this organ. A total of 82 complications occurred in 78 (5.1 percent) of the patients; this is comparable with the rates of 6 to 21 percent that have been reported for conventional cholecystectomy. Overall, the most common complication was superficial infection of the site of insertion of the umbilical trocar. A total of seven injuries to the common bile duct or the hepatic duct occurred during the operation, for a rate of 0.5 percent. Four of the seven injuries were simple lacerations, which were repaired after conversion to conventional cholecystectomy. The incidence of bile-duct injury in the first 13 patients operated on by each surgical group was 2.2 percent, as compared with 0.1 percent for subsequent patients. No complications were attributed directly to either cautery or laser-surgical technique, and similar numbers of complications occurred in academic and private hospitals. The mean hospital stay for the entire group was 1.2 days (range, 6 hours to 30 days). CONCLUSIONS The results of laparoscopic cholecystectomy compare favorably with those of conventional cholecystectomy with respect to mortality, complications, and length of hospital stay. A slightly higher incidence of biliary injury with the laparoscopic procedure is probably offset by the low incidence of other complications.
Rational Design of Hierarchically Open‐Porous Spherical Hybrid Architectures for Lithium‐Ion Batteries

Controlling the internal microstructure and overall morphology of building blocks used to form hybrid materials is crucial for the realization of deterministically designed architectures with desirable properties. Here, integrative spray‐frozen (SF) assembly is demonstrated for forming hierarchically structured open‐porous microspheres (hpMSs) composed of Fe3O4 and reduced graphene oxide (rGO). The SF process drives the formation of a radially aligned microstructure within the sprayed colloidal droplets and also controls the overall microsphere morphology. The spherical Fe3O4/rGO hpMSs contain interconnected open pores, which, when used as a lithium‐ion battery anode, enables them to provide gravimetric and volumetric capacities of 1069.7 mAh g−1 and 686.7 mAh cm−3, much greater than those of samples with similar composition and different morphologies. The hpMSs have good rate and cycling performance, retaining 78.5% capacity from 100 to 1000 mA g−1 and 74.6% capacity over 300 cycles. Using in situ synchrotron X‐ray absorption spectroscopy, the reaction pathway and phase evolution of the hpMSs are monitored enabling observation of the very small domain size and highly disordered nature of FexOy. The reduced capacity fade relative to other conversion systems is due to the good electrical contact between the pulverized FexOy particles and rGO, the overall structural integrity of the hpMSs, and the interconnected open porosity.
Bounded Synthesis of Resilient Supervisors

In this paper, we investigate the problem of synthesizing resilient supervisors against combined actuator and sensor attacks, for the subclass of cyber-physical systems that can be modelled as discrete-event systems. We assume that the attackers can carry out actuator enablement and disablement attacks as well as sensor replacement attacks. We consider both risky attackers and covert attackers in the setup where the (partial-observation) attackers may or may not eavesdrop the control commands (issued by the supervisor). A constraint-based approach for the bounded synthesis of resilient supervisors is developed, by reducing the problem to the Quantified Boolean Formulas (QBF) problem. The bounded synthesis problem can then be solved either with a QBF solver or with repeated calls to a propositional satisfiability (SAT) solver, by employing maximally permissive attackers, which can be synthesized with the existing partial-observation supervisor synthesis procedures, as counter examples in the counter example guided inductive synthesis loop.
Continuous-Flow Process for the Synthesis of 5-Nitro-1,4-dihydro-1,4-methanonaphthalene

In this article, we describe a safe and practical process for the synthesis of 5-nitro-1,4-dihydro-1,4-methanonaphthalene (1) via a continuous-flow reactor. The primary procedures in this process involved not merely the production of isoamyl nitrite but also the temperature-programmed Diels–Alder reaction of an aryne (derived from 2-amino-6-nitrobenzoic acid) with cyclopentadiene in the series flow reactor. The continuous-flow process minimized the accumulation of dangerous isoamyl nitrite and the energetic diazonium salt, and the entire reaction time was held down to 250 s.
Evaluation of the carbon isotope ratios of selected volatiles determined in several citrus authentic petitgrain oils. Bigarade (C. aurantium) petitgrain oil’s first case report

ABSTRACT Selected volatile components were analyzed by gas chromatography (GC) coupled to a combustion-isotope ratio mass spectrometer to assess their δ13C values in authentic citrus leaf oils. In particular were analyzed lemon, mandarin and bitter orange petitgrain oils industrially produced by a local factory. All the samples were then analyzed by gas chromatography mass spectrometry and gas chromatography-flame ionization detection and enantio-GC for the quality assessment of each petitgrain. These values were then compared and genuineness of each sample was defined based on all the different parameters detected. The results show good agreement between the different analytical approaches. In addition in this article are reported for the first time the δ13C values relative to genuine bitter orange petitgrain oil, useful for the quality assessment of this niche product of great economical importance.
Optimization and kinetic modeling of an enhanced bio‐hydrogen fermentation with the addition of synergistic biochar and nickel nanoparticle

The improvement of hydrogen production was achieved by the addition of biochar (BC) and metal co‐factor nanoparticle Ni0 during the dark fermentation. A new hybrid approach by combing the artificial neural networks with the response surface methodology was applied to optimize the hydrogen production. The effects of operating conditions, ie, BC, metal cofactor Ni0, pH, and dosage of microbes, upon the hydrogen production together with the concentrations of other metabolites such as the acetic acid, propionic acid, butyric acid, and ethanol were extensively investigated. From kinetic study of the major metabolites, the acetate pathway was found to be apparently enhanced by the addition of synergistic factors. The modified anaerobic digestion model with the consideration of inhabitation factor was found to best represent the kinetics of hydrogen production and the formation of major metabolites.
Surgical outcomes of arthroscopic rotator cuff repair with modified Mason-Allen suture technique combined with microfracture procedure at the attachment site

Background: Rotator Cuff Tear (RCT) is a lesion that cannot be reversed, usually requiring surgery. Several techniques have been introduced to repair RCT. In general, the purposes of these techniques are aimed at restoring the mechanical strength of the tendons, reducing the rate of tendon re-tear and increasing the rate of tendon healing, thereby increasing functional outcomes after surgery. Material and Methods: This prospective longitudinal followup study included 60 patients of full-thickness RCT who underwent arthroscopic rotator cuff repair with modified Mason-Allen suture technique combined with microfracture procedure at the attachment site between January 2019 and March 2020. The patients were evaluated functional results after surgery based on ASES score and UCLA score. Tendon healing was assessed based on MRI according to Sugaya classification. The average ASES scores before and after surgery were 28.02 ± 15.36 and 96.35 ± 4.57, respectively. The average UCLA score after surgery was 33.07 ± 1.83. Forty-one out of 60 patients had postoperative MRI, showing type I, type II, type III, type IV, and type V tendon healing respectively in 23 patients (56.1%), 9 patients (22.0%), 4 patients (9.8%), 2 patients (4.9%), and 3 patients (7.3%). Conclusions: The arthroscopic modified Mason Allen suture technique combined with microfracture procedure at the attachment site for the treatment of rotator cuff tear had good postoperative results, especially in patients with small and moderate tears in terms of the rate of tendon healing and postoperative shoulder function.

Listening to what trust in news means to users: qualitative evidence from four countries

This report details findings from an inductive, qualitative study of news audiences across four countries, examining varying ways people define the construct of trust in news, how they differentiate between sources, and the role played by digital platforms in how news outlets get evaluated in daily life. Drawing on both focus group discussions and one-on-one in-depth interviews with 132 individuals in Brazil, India, the United Kingdom, and the United States, the report argues that many people focus surprisingly little on the specific journalistic practices employed by news organisations when assessing trustworthiness. Instead, many news consumers fall back on shortcuts involving impressions of brands’ reputations and stylistic differences in the way news gets presented. For those lacking strong trusting relationships to particular news outlets, the experience of navigating information online often reinforced tendencies toward generalised scepticism toward all news—making it that much more challenging for news organizations to build trust with digital audiences.
Deeper Insights into Conformational Analysis of cis-Butene and 1-Alkenes as Monomers and Dimers: QTAIM, NCI, and DFT Approach

A few theoretical and experimental studies have been done so far about the properties and the conformational analysis of alkenes as monomers and dimers. Deeper insights into the conformational analysis of monomers and dimers of alkenes and the relation with boiling point are done in this work. In low-lying cis-butene, there is no repulsive interaction between methyl groups but there is an attractive hydrogen-hydrogen bonding. In monomers of 1-alkenes, the most stable conformer has bent-inward geometry which favors the π bond interaction with methyl/methylene hydrogen/carbon atoms. Conversely, each alkene’s molecule in the corresponding most stable alkene’s dimer has a straight, zig-zag geometry. Two straight, zig-zag alkene’s molecules in the corresponding most stable dimer have only one type of intermolecular interaction (hydrogen-hydrogen bonding). As a consequence, very good linear relationships between a physical property (such as boiling point) and theoretical parameters are obtained.
Selected physical and viscoelastic properties of strawberries as a function of heated-air drying conditions

Abstract The effect of drying conditions on physical and viscoelastic properties of strawberries was investigated. Drying followed falling rate drying period, indicating that internal resistances limited the water transport within the matrix. Increasing drying temperature and duration led to lower color values, moisture content, and volumes. Strawberries presented linear viscoelastic behavior up to 2.5% strain. Drying caused lower relaxation and higher creep due to the loss of stiffness and structural deformation. Burger’s and three-element Maxwell models were well-fitted to describe creep (R2 = 0.971–0.989) and relaxation (R2 ≥ 0.999) behaviors of strawberries, respectively. The first Maxwell element demonstrated the viscoelastic behavior of strawberries ( = 0.54–1.51), while the second and the third elements exhibited the viscous behavior ( = 0.069–0.205, = 0.009–0.047). Strawberries presented solid-like behavior since tan delta (G″/G′) was lower than one for all samples.
Estimation of heritabilities and gene number in the production of provitamin A in carrots.

Broad sense heritabilities and estimates of the number of factors or genes involved in the productjon of phytoene, -carotene, -carotene, a-carotene, Iycopene and total carotenoids were estimated in two different crosses of carrot (Daucus carota L.) with different backgrounds. F2 plants segregating for absence of a-carotene were identified in the cross B493 x QAL. HPLC chromatograms revealed that most of the increase of total carotenoids in high intensity mass selection (HCM), cycle 13, was due to jncrease of a-carotene content than {3-carotene. Broad sense heritabilities values were around or greater than 50% for {3- carotene, -carotene, Iycopene, phytoene and total carotenoid and around 35% for a- carotene in the cross Brasilia x HCM. In the cross orange x white the heritabifities were around or greater than 90%. The estimated number of factors was 4 for a-carotene, 3 for f3- carotene and total carotenes and one for -carotene, Iycopene and phytoene in the orange x dark orange cross, and 4 for a-carotene, 1-2 for Iycopene and total carotenes and 1 for the other carotenes in the orange x white cross.
The Effect of Collagen Activation on Platelet Rich Plasma for Proliferation of Periodontal Ligament Fibroblasts

BACKGROUND: Regenerative procedure in periodontal surgery aims to improve the structure and function of the periodontium to be strong enough to support the teeth. Growth factor is essential in the process of tissue regeneration; it can be generated from the activation of Platelet-Rich Plasma (PRP). In this study, collagen was used as PRP activator. PRP release growth factor from the granules when activated. The aim of this study was to evaluate the effect of collagen on PRP activation and the collagen-activated PRP storage to fibroblast proliferation of periodontal ligament (PDL). METHODS: Fibroblasts of PDL were obtained from extracted premolar. PRP were obtained from 100 mL of blood donors using double centrifugation methods. PRP were activated by collagen and subsequently incubated for 24, 48, 72 and 168 hours; after which the lysate was taken. Fibroblasts were divided into 7 groups, which consisted of one unstimulated group as negative control, one group stimulated by PRP lysate, and five groups stimulated with PRP-collagen lysates that had been incubated for 24, 48, 72 and 168 hours. MTT assay was then performed after 1 and 3 days.RESULTS: The proliferation rate of fibroblasts group stimulated by PRP-collagen lysate was higher than the group stimulated by PRP. The storage of collagen-activated PRP for 7 days at 4°C could increase the proliferation rate.CONCLUSION: The activation of collagen on PRP and the stored collaged-activated PRP could increase the fibroblasts proliferation rate of PDL.KEYWORDS: collagen, platelet-rich plasma, fibroblasts proliferation

Mechanism of adsorption of cadmium and lead ions by iron-activated biochar

Heavy metal removal from aqueous matrices may help reduce disease and cancer incidences. In this study, reed biochar (RBC) and RBC modified by ferrous ammonium sulfate addition (1 mol Fe L-1) were compared for potential Cd and Pb removal from varying pH aqueous solutions. Surface functional groups were identified using Fourier transform infrared (FTIR) analysis, and their surface physicochemical structure was observed using scanning electron microscopy-energy dispersive spectrometry (SEM-EDS). Batch experiments showed that the modified-reed biochar (MRBC) had greater Cd and Pb removal capacities over a wide pH range (1 to 8), as well as greater metal sorption capacities compared to RBC. Metal reaction kinetics occurred relatively quickly (i.e., within 60 min), and Langmuir modeling suggested that Cd and Pb removal by MRBC was maximized at 2.97 mg g−1 and 17.5 mg g−1 at 45 °C, respectively. The MRBC effectively sorbed Cd and Pb likely due to associations with functional groups modified by the Fe addition. In the future, MRBC may be used as an efficient and eco-friendly adsorbent for Cd and Pb removal from aqueous solutions and may help reduce water-borne issues associated with metal contamination.
