Friction and wear of radiofrequency-sputtered borides, silicides, and carbides

Field: Materials Science (Physical Sciences)

The friction and wear properties of several refractory compound coatings were examined. These compounds were applied to 440 C bearing steel surfaces by radiofrequency (RF) sputtering. The refractory compounds were the titanium and molybdenum borides, the titanium and molybdenum silicides, and the titanium, molybdenum, and boron carbides. Friction testing was done with a pin-on-disk wear apparatus at loads from 0.1 to 5.0 newtons. Generally, the best wear properties were obtained when the coatings were bias sputtered onto 440 C disks that had been preoxidized. Adherence was improved because of the better bonding of the coatings to the iron oxide formed during preoxidation. As a class the carbides provided wear protection to the highest loads. Titanium boride coatings provided low friction and good wear properties to moderate loads.

Prevention of transfusion-associated cytomegalovirus infection: defining the method of preparation for leukocyte-reduced blood products [letter; comment]

Field: Medicine (Health Sciences)

Bowden et al' recently reported on a prospective, randomized trial comparing leukocyte-reduced and cytomegalovirus (CMV)-seronegative blood products for the prevention of transfusion-associated CMV infection in which filtration was selected as the means of leukocyte-reduction.They concluded that "filtration is an effective alternative to the use of seronegative blood products for prevention of transfusion-associated CMV infection in marrow transplant patients."This conclusion seems to suggest or may be interpreted as
Mutagenicity and chemical analysis of airborne particulates from a rural area in italy

Field: Environmental Science (Physical Sciences)

Abstract Mutagenic activities of a sample of characterized airborne particulates collected in a rural location near Ispra (Italy) during the summer of 1980 were detected by the Ames test using TA 1537, TA 1538, TA 98, and TA 100 Salmonella strains. Eight chemical classes fractionated from the CH 2 Cl 2 extract of the particulates were bioassayed, and their mutagenicities (TA 98 plus S9) were as follows: organic bases I > polar neutrals > insolubles in cyclohexane > organic acid II > aerosol “in toto” > intermediate neutrals > polycyclic aromatic hydrocarbons > organic acids I > nonpolar neutrals. Periodical samples were taken in the same location from March to December 1981, extracted in dimethyl sulfoxide (DMSO), and directly tested with TA 1537, TA 98, and TA 100 Salmonella strains. For all the strains the mutagenicity varied markedly according to the season, the cold‐month samples being much more mutagenic than the summer‐month samples. The additional of S9 increased the mutagenicity (twofold) of the cold‐month samples. The higher mutagenicity of the samples collected during the cold months could be due to greater amounts of mutagens produced by the combustion processes of domestic heating.
Association of Chest Pain with Rate Pressure Product and ST-segment Changes after Sub Arachnoid Block in Caesarean Section.

Field: Medicine (Health Sciences)

When healthy women undergo caesarean section (CS) under sub arachnoid anaesthesia, transient electrocardiographic changes, such as ST-segment depression and T-wave abnormalities, are observed. During an elective caesarean section under sub arachnoid anaesthesia, about one-third of healthy parturient experience chest pain and ECG changes suggestive of myocardial ischemia. To assess the ST-segment and Rate Pressure Product changes with chest pain in patients with elective caesarean section under subarachnoid block. The Department of Anesthesia, Analgesia and Intensive Care Medicine at Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh was the site of this prospective observational study. The study included 86 healthy women between the ages of 20 and 35 who needed an elective caesarean section under a single shot sub arachnoid block and who visited the Department of Anesthesia, Analgesia, and Intensive Care Medicine at BSMMU in Shahbagh, Dhaka from January 2019 to June 2019. In comparison to the no chest pain group, ST-segment changes among the chest pain group at delivery, 5 minute, 10 minute after delivery and at the end of the surgery were highly significant (p=0.001). Comparatively, Rate Pressure Product changes were found to be significantly higher in the group with chest pain than in the group without chest pain (p=0.001). It is concluded that there is a substantial association of chest pain with rate pressure product and ST-segment changes after subarachroid block in caesarean section.

A 245 Mb/s EPR4 read/write channel with digital timing recovery

Field: Engineering (Physical Sciences)

Modern read/write channels employ discrete-time signal processing techniques to process the signal from the read head. Such systems usually rely on a variable frequency oscillator (VFO) to synchronously sample the data. This read/write channel uses an all-digital PLL (DPLL) to perform timing recovery. The DPLL eliminates the VFO, thus removing the contributions of VFO mismatch and process variations due to sampling frequency error. The only frequency error present in the read data is the spin frequency variation of the disk. To account for spin speed variation, the read signal is oversampled by a small amount. The 18.09 mm/sup 2/ (step and repeat size) chip, uses 0.35 /spl mu/m, 3.3 V single-poly triple-metal CMOS. Apart from the AC coupling capacitors, only one external resistor is required.
EFFECT OF VARIOUS SOURCES OF SULFUR ON YIELD AND SULFUR CONCENTRATION OF CEREALS AND FORAGES

Field: Agricultural and Biological Sciences (Life Sciences)

Field experiments were conducted at three locations in Prince Edward Island to determine the effects of various sources of S (Agri-Sul, gypsum, and Urea-Sul) on S concentration of tissue and yields of forages and cereals. Gypsum was effective in increasing the S concentration in plant tissues. Agri-Sul at 10–80 kg S∙ha −1 was generally ineffective in increasing the S concentration of forages and cereals. In the absence of added S (check treatments), the plant tissue S concentrations in alfalfa (Medicago sativa L.) and timothy (Phleum pratense L.) ranged from 0.18 to 0.39 and from 0.14 to 0.27%, respectively. In wheat (Triticum aestivum L.) and barley (Hordeum distichon L.), the S concentrations varied from 0.12 to 0.26 and from 0.13 to 0.20% in the boot stage tissue and grain, respectively, in the check treatments. In general, the S concentration was higher in the boot stage tissue than in the grain. Pea (Pisum sativum L.) seeds and vegetative material from the check treatments contained 0.19–0.24% and 0.17–0.36% S, respectively. Gypsum or Urea-Sul did not increase the yields of forages or cereals. In one instance Agri-Sul slightly increased the alfalfa yield (5–8.5%), but this was not associated with tissue S increases. Plant tissue S levels as low as 0.12–0.18% appeared to be adequate for barley, wheat, timothy, peas, and alfalfa. Key words: Sources of sulfur, tissue S, yields, cereals, forages
Studies on buffalo calf mortality in Jabalpur district of Madhya Pradesh

Field: Veterinary (Health Sciences)

The Jabalpur region of Madhya Pradesh comprises of six tehsils namely Patan, Kundam, Majholi, Sihora, Panagar and Shahpura which cover densely buffalo populated area. Patan, Kundam and Majholi Tehsils are one of them. The data on mortality of buffalo calves was collected by random survey methods from 60 farmers (10 farmers of each villages) of 06 villages of 03 Tehsils of Jabalpur District MP. The data was based on the interview schedule. The morality data were categorized based on the sex and age group during the last one year. The result of the present study indicated that overall buffalo calf mortality in and around Jabalpur district was 42.11%. Mortality was higher in male calf than the female calves due to the negligence towards male calf. Highest mortality was recorded in the age group of calves below three months. It was also found that significantly (P>0.05) higher mortality was observed in male calf compared to female calves (60.47% vs. 23.53%).

Cross-Sectional Study on Relationships Among FoMO, Social Influence, Positive Outcome Expectancy, Refusal Self-Efficacy and SNS Usage

Field: Psychology (Social Sciences)

Objectives: Use of social networking sites (SNS; i.e., Facebook or Instagram) is common, and people use SNS to communicate and share information. Literature indicates the extent of SNS usage could be influenced by fear of missing out (FoMO). FoMO means a process of appraisal and psychological need for SNS use. This study proposes a model that integrates three determinants of social cognitive theory (SCT) to explain the impact of FoMO on SNS usage. Design: A cross-sectional study was conducted using data from 259 participants recruited from a website. Main Outcome Measures: The analysis focused on FoMO, social influence, positive outcome expectancy, refusal self-efficacy, and SNS-related behavior cloud-based sites. Data are examined using descriptive analysis and structural equation modeling. Results: The proposed model reported proper goodness of fit. FoMO did not directly or indirectly impact SNS usage through the determinants of SCT. However, social influence and refusal self-efficacy had a direct effect. Conclusions: The roles of the three determinants of SCT vary by stage of SNS usage. FoMO and refusal self-efficacy are more strongly related with SNS addiction. Further research, particularly longitudinal and intervention studies, is needed to examine the effects of specific factors on SNS addiction.
Does Cannabis Dependence Add on to the Neurocognitive Impairment Among Patients With Opioid Dependence? A Cross‐Sectional Comparative Study

Field: Psychology (Social Sciences)

Background and Objectives Chronic opioid exposure has been linked with neurocognitive impairments. Evidence of residual impairment with cannabis use is less consistent. We investigated whether patients with opioid and cannabis dependence perform poorly compared with those with opioid dependence alone. Methods We recruited three groups of participants aged 18 to 55 years: opioid and cannabis dependence (OCaD; n = 21), only opioid dependence (OD; n = 19), and a control group (HC; n = 20). Subjects with other substance use, human immunodeficiency virus, head injury, epilepsy, and severe mental illness were excluded. Cognitive tests, performed after at least 1 week of abstinence, consisted of the Wisconsin card sorting test (WCST), Iowa gambling task (IGT), trail making tests A and B (TMT‐A and B), verbal and visual N‐back test (NBT), and standard progressive matrices for intelligence quotient (IQ). The general linear model was used to compare the groups with age and years of education as covariates. Results IQ and severity of opioid dependence were comparable in the three groups. The mean duration of cannabis use was 76.2 (±39.4) months. Compared with the HC, both OD and OCaD had significant impairment on the IGT, WCST, TMTs, and NBT. No significant group difference was observed between the OD and OCaD groups. Discussion and Conclusions Opioid dependence is associated with impairments in decision making, executive function, working memory, and attention. Co‐morbid cannabis dependence had similar profiles of cognitive impairments. Scientific Significance Co‐morbid cannabis dependence might not add on to the existing cognitive dysfunction in opioid dependence. Further studies should be done with a larger sample.

Operationalising Ambidexterity: The Role of "Better" Management Practices in High-Variety, Low-Volume Manufacturing

Field: Business, Management and Accounting (Social Sciences)

Innovation and change are fundamental to the long-term sustainability of any organisation. Whilst it is important to improve operating efficiency in the bid to become more cost competitive, there is still an underlying need to venture out of the norm and explore new opportunities. Though a great deal of research has emerged regarding the achievement of ambidexterity, there remains a gap in understanding how this is actually operationalised in organisations. This paper takes aim at this problem in the context of SME manufacturers that produce a high variety of customised products at low volumes (HVLV). Under such circumstances, ambidexterity appears intuitively easier to achieve given the manufacturer is designed to be as flexible as possible in the first place - though, it would seem this may be to their detriment. Based on a literature review and drawing from ambidexterity and organisational theory, our contribution is geared towards investigating the underlying mechanisms that make HVLV manufacturers ambidextrous in the first place. In particular, we concern ourselves with exploring how ambidexterity is enacted through what are deemed "better" management practices that result in innovative organisations. By better understanding the more latent characteristics of HVLV manufacturers, we shed some light on the interactions between external and internal influences affecting the impact of ambidexterity under such an environment. Further theoretical and managerial implications are discussed.
Sensitivity analysis and shape optimization for preform design in thermo-mechanical coupled analysis

Field: Engineering (Physical Sciences)

In complex forging processes, it is essential to find the optimal deformation path and the optimal preform shape that will lead to the desired final shape and service properties. A sensitivity analysis and optimization for preform billet shape in thermo-mechanical coupled simulation is developed in this work. Non-linear sensitivity analysis of temperatures, flow-stresses, strains and strain-rates are presented with respect to design variables. Both analytical and finite-difference gradients are employed to validate the effectiveness of sensitivity analysis developed in this work. Numerous iterations of coupled thermo-mechanical analysis are performed to determine an optimum preform shape based on a given criterion of minimizing the objective function on effective strain variance within the final forging. The design constraints are imposed on die underfill, material scrap, folding defects and temperatures. In addition, a method for material data processing is given in order to determine the flow stress and its derivatives. The shape optimization scheme is demonstrated with the preform designs of an axisymmetric disk and a plane strain problem. Copyright © 1999 John Wiley & Sons, Ltd.
The effect of melt temperature treatment on the microstructure of Al-25%Si alloy

Field: Materials Science (Physical Sciences)

The effect of melt temperature treatment on the microstructure of Al 25%Si alloy has been studied in this paper. It is found that melt temperature treatment can make the primary crystal grains of Al 25%Si alloy be fined considerably. The size of the primary crystal grains in Al 25%Si alloy is decreased from 100 μm to 15 μm. The efficiency of melt temperature treatment on Al 25%Si alloy dependents on the degrees of the temperature at which the higher and lower temperature melts are mixed. The primary crystal grains of Al 25%Si alloy decrease as the temperature of the higher temperature melts increases. On condition that the temperature of the lower temperature melts is constant, the primary crystal grains of Al 25%Si alloy first decrease as the temperature of the lower temperature melts increases; then, the primary crystals grains of Al 25%Si alloy increase with the temperature of the lower temperature melts when the temperature of the lower temperature melts exceeds 630 ℃.
Research on Packaging Design of Take-Out Food Oriented Towards the Usability Enhancement

Field: Engineering (Physical Sciences)

Usability enhancement of take-out food packaging in its whole life circle was analyzed in this paper from the standpoint of businesses, shop assistants, consumer and environment, respectively. Results indicated that usability enhancement of take-out food packaging can be achieved by taking following measures: producing universal packages as soon as possible, reducing packaging decoration design, decreasing space occupation by using foldable packages, designing self-sealing and auto end-locked structure to facilitate enclosing and opening of packages, reducing quantity of packaging materials. These results provide packaging designers (or more broadly, design decision makers) with more advanced design concepts in the process of take-out food packaging design.

P-989. Respiratory virus infections and symptoms for mothers of infants with acute respiratory infection

Field: Medicine (Health Sciences)

Abstract Background It is recommended that women receive 4 vaccines (influenza, SARS-CoV-2, respiratory syncytial virus (RSV), Tdap) during pregnancy. Among infants with acute respiratory infection (ARI), limited data exist on the burden of viral infections in their mothers. The objective of this study was to describe ARI symptoms and viral infections in the biologic mothers of infants with ARI. Methods Symptomatic infants &lt; 12 months of age with ≥1 ARI symptom for &lt; 7 days enrolled in the New Vaccine Surveillance Network (NVSN) in Pittsburgh, Pennsylvania were recruited along with their biologic mothers to a sub-study during 3 consecutive influenza seasons from 2021 to 2024. Infant ARI symptoms and mid-turbinate (MT) nasal swabs were collected through NVSN. For mothers, we collected presence/absence of ARI symptoms in the preceding 7 days and MT nasal swabs. All MT swabs were tested with the same in-house RT-PCR for 18 viruses/subtypes. Cycle threshold (CT) was compared between mothers and infants using Student’s T-test, where higher CT indicates lower viral load.Figure 1.Maternal and Infant Respiratory Virus Infections at Time of Presentation for Infant’s Acute Respiratory Infection. Results From 124 mother-infant pairs, 100% (N=124) of infants vs. 37% (N=46) of women reported ≥ 1 ARI symptom in the preceding 7 days. 53% (N=66) of women had no detectable virus (Fig 1). 68% (N=45) of those women had no symptoms, while 32% (N=21) had ≥ 1 symptom (Table 1). From the 47% (N=58) of women with detectable virus, 45% (N=56) had one virus, 2% (N=2) had two (Fig 1). 97% (56/58) had the same virus as their infant. Vaccine preventable infections occurred in 17% of women (SARS-CoV-2 N=4, influenza N=2, RSV N=15; 20/21 were unvaccinated for that pathogen) and 39% of infants (SARS-CoV-2 N=6, influenza N=5, RSV N=25). CT for RSV and coronaviruses was higher (i.e. lower viral load) for women compared to infants (Fig 2). Among women with detectable virus, 57% (N=33) had no symptoms, while 43% (N=25) had symptoms (Table 1).Figure 2.Maternal and Infant Semi-Quantitative Viral Load Conclusion Concordant viral infection occurs in half of mothers who have an infant with ARI. However, semi-quantitative viral load is similar or lower in mothers, possibly due to prior infection or vaccine. Additionally, the majority of maternal infections are asymptomatic. Pregnancy vaccines are likely to further reduce detectable and symptomatic vaccine-preventable infections in mothers, which may further enhance infant protection.
