Knowledge management implementation in small and micro KIBS: A categorization
Authors: Bolisani Ettore , Scarso Enrico , Ceccato Riccardo , Zieba Malgorzata 
Published: July 2022

AbstractThe main goal of the paper is to provide a statistical categorization of small and micro knowledge‐intensive business service (KIBS) companies, based on their knowledge management (KM) attitude. Since knowledge is the main production factor and output of these companies, it is essential to achieve a better understanding of how they manage this resource. A questionnaire‐based survey was conducted on a sample of Polish small and micro KIBS operating in various service sectors. A cluster analysis of the data was performed, to categorize the sample according to the KM attitude of the companies. Three main groups of companies were identified, varying in terms of their levels of “knowledge needs”, “intensity of use” of KM practices and “perceived barriers to KM implementation”. This classification is shown to characterize attitudes towards KM to a higher level of statistical significance than do structural characteristics. The survey was based on a single country sample. On the one hand, this provides consistency to the analysis. On the other hand, further insights can be obtained by a multi‐national study. In addition, cluster analysis is exploratory in nature. The results provide useful insights for policy makers (to formulate policies for facilitating KM implementation in small KIBS) and managers (to reflect on the KM attitudes of their company). The statistical categorization of small and micro KIBS in terms of their KM attitude has been very rarely undertaken. Even the most recent investigations of KM issues used samples from large companies.

Published: July 2022

ObjectiveTo objectively identify and quantitate presenting nasal symptoms in patients with a septal perforation using the validated NOSE‐Perf scale.Study DesignCase series retrospective review.MethodsThe medical records from August 2018 through January 2022 of patients at a tertiary care academic center with a septal perforation, and who completed the NOSE‐Perf questionnaire, were reviewed. Perforation symptoms were identified and quantified using the 12‐item NOSE‐Perf scale (score range 0–48). NOSE‐Perf findings were correlated to patient demographics, perforation etiology, and perforation length. NOSE‐Perf scores of patients who pursued treatment were compared with those who did not.ResultsNOSE‐Perf data were collected from 202 patients. Nasal crusting was noted in 94.1% of patients and was the most severe symptom reported (mean 2.9 of 4.0). Nasal congestion, difficulty breathing, and nasal obstruction followed in prevalence and severity. The mean total NOSE‐Perf score was 23.7. Linear regression analysis demonstrated a weakly negative association of NOSE‐Perf score with patient age and weakly positive association with increasing perforation length. NOSE‐Perf scores were significantly higher in women and in patients pursuing treatment.ConclusionThis is the first study to use the validated NOSE‐Perf scale to objectively characterize and establish baseline septal perforation symptomatology. The NOSE‐Perf scale can play a role in the standardization of perforation evaluation and treatment outcomes assessment. Laryngoscope, 133:1315–1320, 2023
The role of internal nitrogen loading in supportingnon‐N‐fixing harmful cyanobacterial blooms in the water column of a large eutrophic lake

Published: July 2022

AbstractWestern Lake Erie cyanobacterial harmful algal blooms (cyanoHABs) occur every summer as a result of anthropogenic nutrient loading. Although the physiological importance of nitrogen (N) in supporting bloom biomass and toxin production is established, the role of internal N recycling in the water column to support bloom maintenance is not as well understood. Over three field seasons (2015–2017), we collected water from western Lake Erie and employed bottle incubations with15N‐ammonium () enrichments to determine regeneration and potential uptake rates in the water column. Potential uptake rates followed spatial and seasonal patterns, with greatest rates measured nearest the Maumee River inflow and during peak bloom months (August and September). Regeneration followed a similar spatial pattern but was greatest in early summer (June and July) and supported ~ 20–60% of potential demand during the height of the bloom. Basin‐wide internal regeneration during the April–October period could supply at 60–200% of annual external N loading to the western basin. These results help explain how non‐N‐fixing cyanoHABs in Lake Erie and other large, eutrophic lakes continue producing biomass and N‐rich toxins long after spring nutrient loads are exhausted or transported to other areas. Internal N loads are ultimately driven by external N loads; in low precipitation years, external nutrient loads result in smaller blooms, producing less substrate for subsequent internal N loads. Overall, these findings, along with others, confirm that both internal and external N loading must be considered when evaluating cyanoHAB management strategies.

AbstractBackgroundDue to the precise vaporization of the novel 450 nm blue diode laser in soft tissues (i.e., bladder and colon) in our previous studies, porcine stomach tissues were applied here to certify its efficacy in endoscopic mucosal resection (ESR)/endoscopic submucosal dissection (ESD) for hypothetical lesions ex vivo and in vivo.Materials and MethodsIn an ex vivo study of ESR, 20 pieces of tissues (8 cm × 6 cm) from 7 fresh stomachs after spraying saline were vaporized with a three‐dimensional scanning system using the blue diode laser at a maximum of 30 W, a different treatment speed and working distance (WD). In ex vivo ESD, 18 pieces of tissues from 6 fresh stomachs were used and the same laser parameters were used to perform the procedure. The depth, width, and coagulation of the laser vaporization were measured. Furthermore, the large scales (2.0 cm × 1.5 cm) for 18 hypothetical lesions of the gastric mucosa and submucosa of the 6 fresh stomachs were also resected with a modified flexible endoscope. In vivo, six hypothetical lesions of six porcine were vaporized by the novel blue laser, and the resultant lesions at the acute and chronic stages were assessed by the naked eye and hematoxylin and eosin staining.ResultsIn the contact mode, more tissue was vaporized, and the thickness of the coagulation was stable when the WD was 0−2 mm, whose value varied from 0.33 to 1.73 mm. In the gastroscopy model, the mean thickness of coagulation from the mucosa was 0.67 mm, and a significant carbonization zone was not observed. In vivo, the laser beam could accurately act on the hypothetical target. No bleeding and clear vision were present in the procedure. After 3 weeks, tissue healing was well recovered after laser coagulation, resection, and submucosal dissection.ConclusionsIn the present study, the novel 450 nm blue diode laser exhibited ideal vaporization and thinner coagulation thickness in the porcine stomach, which indicated that it could be alternately used as a new device for stomach lesions.

AbstractObjectiveTo examine the effects of the selective 5‐HT1A receptor agonist, NLX‐112, on urethral function in streptozotocin‐induced diabetic rats.Materials and MethodsFemale Sprague–Dawley rats (n = 32) were divided into two groups: rats with type 1 diabetes mellitus (T1DM) and age‐matched normal control rats (NC). T1DM was induced by intraperitoneal injection of streptozotocin (65 mg/kg). Isovolumetric cystometry and urethral perfusion pressure (UPP) were evaluated 10 weeks postinjection in rats (n = 9 per group). The selective 5‐HT1A receptor antagonist, WAY‐100635 maleate salt, was administered after NLX‐112 hydrochloride dose–response curve was generated (intravenously). The remaining rats were used for immunofluorescence and Western blot assays.ResultsCompared to controls, type 1 diabetic rats (T1D rats) had lower maximal intravesical pressure (IP max) and UPP changes. In T1D rats, NLX‐112 hydrochloride (0.003–1.0 mg/kg) induced dose‐dependent decreases in UPP nadir, IP max, high‐frequency oscillations (HFOs) rate; and increases in UPP change and HFOs amplitude. WAY‐100635 maleate salt (0.3 mg/kg) partially or completely reversed the NLX‐112‐induced changes. Immunofluorescence revealed that 5‐HT1A receptors were found in the L6‐S1 spinal cord dorsolateral nucleus, but the expression was significantly higher in the T1D rats. Additionally, Western blot showed there were significantly more 5‐HT1A receptors in the ventral L6‐S1 spinal cord of T1D rats.ConclusionsUrethral dysfunction in T1D rats was improved by NLX‐112. 5‐HT1A receptors were upregulated in the dorsolateral nucleus of L6‐S1 spinal cord in T1D rats. These findings suggest that NLX‐112 may constitute a novel therapeutic strategy to treat diabetic urethral dysfunction.
Effect of lamellae thickness on bubble dissolution in rotomoulding

AbstractThis paper is devoted to the study of bubble dissolution of the melted polymer in rotomoulding process. Two types of linear low‐density polyethylene (LLDPE) having the same properties, that is, melt index, melting point, crystallinity, viscosity, comonomer type, but different lamellae thickness were investigated. The results showed that bubbles in rotomoulded parts impaired the low‐temperature impact and LLDPE with thicker lamellae showed better bubble dissolution. Furthermore, as the annealing treatment was applied to the LLDPE powders, lamellae thickness distribution derived from Thomson–Gibbs equation coincided with bubble observation, suggesting that the improvement in bubble dissolution is reasonably attributable to annealing which makes the lamellae of treated LLDPE thick. In addition, the rheological measurements showed that modulus was built‐up with time indicating intermediate disentanglements are formed. Correlation between lamellae thickness distribution derived from differential scanning calorimetry data and experimental rheological result suggests that thicker lamellae is related to enhancing bubble dissolution. Consequently, it is reasonable to consider that the thicker lamellae is quite benefit for bubble dissolution, which could be well explained by the free volume according to free volume theory. LLDPE having thicker lamellae contains more free volume resulting in better bubble dissolution.

AbstractFully conjugated polyazomethines (PAZs) exhibit large amounts of micropores among their many short branches in relatively planar structures based on their fully conjugated configuration. However, these fully conjugated structures cause insolubility and non‐processability of the PAZs because they may have strong stacking interactions due to their planar structures. In this paper, to overcome this problem, three short lengths of oligodimethylsiloxane (ODMS) grafts (x = 9, 18 and 39) were introduced by end‐capping reaction of aldehydes at the end of insoluble PAZs with amino‐terminated ODMSs as end‐capping agents. As a result, the insoluble PAZs became almost soluble (solubility > 95–100%) and their molecular weight could be estimated using gel permeation chromatography (Mw = 15.9 × 103 g mol−1). PAZ‐embedded mixed‐matrix membranes (MMMs) were fabricated using blend solutions containing only small amounts (1.0 wt%) of the solubilized PAZs with ODMS grafts and crosslinked polydimethylsiloxane (PDMS). The PAZs/PDMS MMMs showed ultrahigh permeability to oxygen which achieved 8600 barrer without a decrease of the original permselectivity of PDMS. The excellent oxygen permeability of the PAZs/PDMS MMMs may be caused by an effective increase of porosity based on the fully conjugated PAZ nanosheet. © 2022 Society of Industrial Chemistry.

Published: July 2022

AbstractThis research aims to examine the self‐regulation of students with different achievement levels toward science learning based on Zimmerman's model including three phases: forethought, performance, and self‐reflection. The research was conducted based on the case study from the qualitative research method. The study group consisted of 12 students who have different academic achievement levels and are studying at different levels of a middle school in Kayseri province, Turkey. The data of the research were collected through semistructured interviews and analyzed using content analysis. It was determined that each phase of self‐regulation was not compatible with academic achievement, and individual differences came to the fore in students' self‐regulation. The authors concluded that a student's level in all subdimensions of self‐regulation was not the same. They also found that not only academic achievement affected the subdimensions of self‐regulation, but also individual factors and differences.
Registration of two oilseed sunflower germplasms, HA‐R18 and HA‐R19, resistant to sunflower rust

Published: July 2022

AbstractSunflower rust, incited by the fungus Puccinia helianthi Schwein., is a serious fungal disease in the sunflower (Helianthus annuus L.) growing areas worldwide, with an increasing importance in North America in recent years due to the frequent evolution of new pathogen races. HA‐R18 (Reg. no. GP‐377, PI 698197) and HA‐R19 (Reg. no. GP‐378, PI 698198) are rust‐resistant germplasm lines that were developed and released cooperatively in 2020 by the USDA‐ARS, Sunflower and Plant Biology Research Unit and the Agricultural Experiment Station of North Dakota State University. The rust resistance in HA‐R18 and HA‐R19 originated from KP193 and KP199, respectively, which were identified segregating for rust resistance after screening of 58 sunflower lines introduced from South Africa. Rust evaluation of HA‐R18 and HA‐R19 with 11 P. helianthi races indicated that both lines exhibited resistance to the most rust races tested including the most predominant and the most virulent races currently identified in the United States. HA‐R18 and HA‐R19 possess the new rust resistance genes R17 and R18, respectively, both of which have been mapped to sunflower chromosome 13. The two new lines will diversify the pool of rust resistance genes and should serve as useful sources of rust resistance in sunflower.
An atmospheric pressure glow discharge in air stabilized by a magnetic field and its application on nitrogen fixation
Authors: Li ZhiYu , Nie LanLan , Liu DaWei , Lu XinPei 
Published: July 2022

AbstractAn atmospheric pressure glow discharge in air stabilized by a magnetic field is reported. The plasma is fixed at a position when the direction of the Lorentz force and the direction of the air flow is opposite. Under such condition, a stable glow discharge can be achieved and the plasma parameters can be independently controlled by the applied voltage, the magnetic field and the air flow rate, which is not the case for the widely used gliding arc (GA) discharge. For applied voltage of 6.5 kV, air flow rate of 2 L min−1, and magnetic field of 0.11 T perpendicular to the paper pointing outward, the discharge voltage (Vdis) and discharge current (Idis) are 1.2 kV and 49.7 mA, respectively. The rotational and vibrational temperature is about 3420 K and 4550 K, respectively. The electron density is on the order of 1014 cm−3 and the reduced electric field of plasma is about 36.9 Td, which is favorable for vibrational excitation of N2 to promote the production of NOx. As the plasma is fixed at a position, all the gas has to pass the plasma region and treated by the plasma when they are flowing, which is not the case for GA discharge where only a little percentage of gas is actually treated by the plasma. The energy cost of NOx production for the plasma stabilized by magnetic field of 0.19 T pointing outward is about 2.65 MJ mol−1, which is 41% lower than the GA discharge.

AbstractWhile care models adapt to the COVID‐19 pandemic with virtual and hybrid visits, clinical factors associated with treatment changes among ambulatory pediatric pulmonary arterial hypertension (PAH) patients are not well characterized. To understand which data critically altered treatment recommendations, we conducted a retrospective review among ambulatory children with Group 1 PAH to determine optimal visit and diagnostic strategies. Changes in management included: unplanned new treatments, dose modifications of vasodilators or diuretics, unscheduled hospitalizations, or changes to activity recommendations, catheterization schedule, or other testing. Factors prompting management changes were classified as symptoms, exam findings, or diagnostic tests. Across 398 ambulatory visits by 48 patients, 38 patients (79%) at 88 visits (22%) required change in management, most commonly in targeted PH medication. Changes were driven by symptoms alone (15%), diagnostic testing alone (47%), exam only (2%), symptoms and exam (2%), combination of testing and symptoms or testing and exam (25%), and other reasons (9%). Patients with World Health Organization functional Class IV (odds ratio [OR] 9.04 vs. Class I, p = 0.014) or Class III (OR 2.08 vs. Class I, p = 0.050) were more likely to undergo change in management. However, among Class I patients, 18% of visits generated changes in management because of test findings. While multiple factors affect management in ambulatory pediatric PH, neither symptoms nor exam was sufficient for identifying patients warranting clinical change in management. Testing accounted for most changes. Thus, in‐person or hybrid surveillance including history, exam, and diagnostic testing remains essential for optimal management of pediatric PAH.
Ion–shift reagent binding energy and the mass–mobility shift correlation in ion mobility spectrometry
Authors: Fernandez‐Maestre Roberto , Tabrizchi Mahmoud , Meza‐Morelos Dairo 
Published: July 2022

RationaleIon mobility spectrometry (IMS) detects illegal substances and explosives in airports, ports, and customs. This is complicated by false positives caused by overlapping peaks. Shift reagents selectively change ion mobilities through adduction with analyte ions. This discriminates false positives because interferents and illegal substances respond differently to shift reagents.MethodsWe introduced five different shift reagents using electrospray ionization–IMS–mass spectrometry to study the effect of interaction energy, intermolecular bonds, and analyte size on ion mobility shifts. Analyte ion–shift reagent interactions were calculated using Gaussian.ResultsThe mobility shifts showed a decreasing trend as the molecular weight increased for a series of ten compounds. The shift in drift time better reflected the pure effect of shift reagents. Valinol was an exception to this trend because it had a low binding energy interaction with all shift reagents and, consequently, its clusters were short‐lived. This produced fewer collisions against the buffer gas and a shorter drift time, compared to ions of similar molecular weight.ConclusionsThe results of this investigation are important for understanding the behavior of shift reagents in resolving overlapping peaks that cause interferences. The suppression of false positives eases the transit of passengers and cargos, increases the confiscation of illicit substances, and saves money and distress due to needless delays in customs and airports.
Biosphere‐based sustainability in local governments: Sustainable development goal interactions and indicators for policymaking
Authors: Nerland Rita , Nilsen Heidi Rapp , Andersen Bjørn 
Published: July 2022

AbstractKnowledge on sustainable development goals (SDGs) interactions has a bias toward global perspectives and lacks regional or country‐specific differentiation. This paper takes a biosphere‐based sustainability approach and assesses SDG interactions in a local governmental context. We start by addressing how the SDGs promote a biosphere‐based sustainability. Here, we find a range of opinions and we settle on a set of SDGs. Second, we explore how a set of sustainability indicators are connected to the SDGs and biosphere‐based sustainability. We conduct a case study and develop an SDG interaction model, and further compare global and local level interactions. We find that the local level has some differences compared to global level findings. However, the distribution among synergies and trade‐offs was found to be quite coherent. Our SDG interaction model connects sectors both within a single government and between governmental levels and can as such facilitate policy coherence. The main contribution of this study is our unique approach of conducting a local level assessment which aligns an existing sustainability measurement system with interaction research.

AbstractAryl halides containing electron‐withdrawing substituent(s) at ortho and para position undergoes aromatic nucleophilic substitution reaction with sulfur nucleophile present in dithiocarbamate anions at room temperature. In the present study, several cyclic and acyclic secondary amines reacted in situ with carbon disulfide to form dithiocarbamate anions, which then react with different haloarenes resulting in the formation of aryldithiocarbamates. A series of aryldithiocarbamates are obtained in high yields by this procedure.

Published: July 2022

AbstractOptical rectennas extend the electromagnetic wave rectification process into the visible regime and provide a route toward high‐performance photodetection and energy harvesting. Here, the promise of 2D materials toward on‐chip optical rectennas is demonstrated. A self‐aligned patterning process yields lateral MIM structures where a nanometer‐sized air gap separates a 2D material contact from a metal electrode. This device can be scalably produced in large arrays using established microfabrication techniques. Different from previous approaches, the performance of the 2D rectenna can be adjusted through electrostatic gating. Optimization of the band alignment leads to strong rectification at wavelengths around 500 nm and clear polarization control. Comparison of wavelength‐dependent rectenna performance with a photon‐assisted tunneling model reveals a tenfold increase in photon‐electron coupling over nanotube‐based rectennas. The results highlight the potential of 2D material‐based rectennas for future quantum computing applications.
