One‐Pot Synthesis of Lanthanum‐Doped Carbon Dots From Fumaroyldiglycine With Antioxidant and Antimicrobial Activities

Field: Chemistry (Physical Sciences)

ABSTRACT This study presents a novel and simplified method for generating lanthanum‐nitrogen‐enriched carbon dots (La‐NCDs) in a single step, using 2,2'‐(fumaroylbis(azanediyl))diacetic acid (FDG) as a starting material. The resulting lanthanum‐nitrogen‐carbon dots were carefully analyzed for their consistent structure, optical properties, and size, all of which indicated successful activation. The research then explored the antimicrobial potential of both La‐NCDs and FDG against common pathogens such as Staphylococcus aureus, Escherichia coli , and Candida albicans . La‐NCDs inhibit microbes greatly, demonstrating inhibition zones of up to 41 mm and minimum inhibitory concentrations (MICs) of 500–2000 µg/mL depending on the microbe. In contrast, FDG displays weak antimicrobial activity. The 1,1‐diphenyl‐2‐picrylhydrazyl/2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) free radical scavenging assay was used to estimate the antioxidant properties of the materials. La‐NCDs were more efficient as antioxidants than FDG and inhibited free radicals with an IC 50 of 121.88 µg/mL. This indicates that La‐NCDs antioxidants may find their place in biomedical applications concerning microbial infection and oxidative stress treatment.
Dominator color class dominating sets in triangular ladder and mobius ladder graphs

Field: Mathematics (Physical Sciences)

Let $G=(V,E)$ be a graph. Let $\C= \{ \C_1, \C_2, \dots, \C_{\chi}\}$ be a proper coloring of $G$. $\C$ is called dominator color class dominating set of $G$ if each vertex $v$ in $G$ is dominated by a color class $\C_i\in \C$ and each $\C_i\in \C$ is dominated by a vertex $v$ in $G$. The dominator color class domination number is the minimum cardinality taken over all dominator color class dominating sets in $G$ is denoted by $\gamma_\chi^{d}(G)$. In this paper we obtain $\gamma_\chi^{d}(G)$ for triangular ladder graph and mobius ladder graph.
Bus IC Card Swiping Behavior Recognition Based on Multivariate Data Fusion and Venn Diagram

Field: Computer Science (Physical Sciences)

In view of the problem that bus IC card data cannot be identified and separated due to cross-section card swiping, substituted swiping and missing swiping, this paper proposes a special algorithm of bus IC card swiping behavior recognition based on multivariate data fusion and Venn diagram. It is based on the existing data of swiping card of a single passenger on the bus at the same time, data of regular bus operation information, data of regular bus stop and data of boarding stations for passengers who swipe their card. Firstly, the data is preprocessed to delete the noise data in the source data which is caused by GPS missing due to weather and the card reader fault that causes the same card to be swiped many times. And data matching is based on the card swiping data of the same card number, transaction date and the same train number within the specified time threshold are matched with the data of boarding, and the time difference threshold of transaction time is set as 30 seconds. Secondly, through this process, the cross-section card swiping, generation card swiping and missed card swiping population are identified and separated, and the number of population and IC card number are counted. Using the Venn diagram, we can clearly demonstrate the structural relationship between cross-section card swiping, substituted swiping and missing swiping. Finally, the data of passengers on and off the bus are completed to obtain correct passenger flow analysis and prediction data, and the revenue analysis is carried out. After identifying 8,163,017 IC card swiping data of cross-section buses in Xiamen city in November 2018 according to the method in this paper, a total of 5,123,694 people used IC card to take cross-section buses, and 1,503,237 people were found to have swiped card across sections, 506,284 people were swiped on behalf of others, and 289,550 people missed data.
Extracellular enzymes: gene regulation and structure function relationship studies.

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

The first conclusion that one could make from the literature covered in this section is that most single mutations in subtilisin BPN'n do not cause major structural alterations. Even multiple mutations, though they may cause local minor perturbations at each of the altered sites, do not affect the overall structure to a large degree. Bott and Ultsch (1986) observed that the subtilisin BPN' structure is very tolerant of single mutations, and this tolerance may have been necessary for survival of the enzyme during the course of evolution. This structural tolerance is not all that surprising if one considers that the structure of subtilisin Carlsberg is very similar to that of subtilisin BPN' while the protein sequences differ by 31%. A superposition of the 274 alpha-carbon atoms of the two enzymes gives a root mean square (rms) deviation of 0.053 nm, a value indicating significant structural similarity (McPhalen and James 1988). Furthermore, the fungal enzyme proteinase K, which is classified as part of the subtilisin family, has approximately 38-40% sequence homology with bacilli subtilisins, particularly in the catalytic site and substrate-binding regions (Betzel et al. 1988). For these sequence-homology regions there is also a structural similarity indicated by a least squares superposition of alpha-carbons giving an rms deviation of 0.11 nm (Betzel et al. 1988). Thermitase, also a member of the subtilisin family, has 47% sequence homology to subtilisin BPN' (Gros et al. 1989). If the best 203 alpha-carbon atoms are superposed, then an rms deviation of 0.05 nm is obtained (Gros et al. 1989). Apparently a significant amount of sequence variation still allows for overall structural similarities in the subtilisin family of enzymes. Though the overall structure of subtilisin is not easily perturbed by single or even multiple mutations, it is clear from the evidence reviewed here that single mutations can lead to very significant effects on the catalytic efficiency, substrate preference, and stability of the enzyme. Analyzing the structural alterations in subtilisin mutants will lead to an understanding of the molecular effects of the mutations at the atomic level. This understanding enables investigators to model and predict the effects of other substitutions, and allows them to focus their efforts on those mutants that are most likely to have the desired properties.(ABSTRACT TRUNCATED AT 400 WORDS)
DEVELOPMENT AND UTILIZATION OF NITROGEN FROM SUNN HEMP AND AMMONIUM SULFATE BY SUGAR CANE RATOON

Field: Agricultural and Biological Sciences (Life Sciences)

The utilization of nitrogen by sugar cane (Saccharum officinarum L.) fertilized with sunn hemp (Crotalaria juncea L.) as green manure and ammonia sulfate and its residual effect during two cuts were evaluated using 15N tracer technique. The amounts of 195.8 kg and 70 kg of N by hectare were added respectively as sunn hemp (SH) and ammonium sulfate (AS), in the following treatments: Control; AS-15N; SH-15N + AS; SH-15N; AS-15N + SH. Five samples of +3 leaves were collected and two meters of the sugar cane plants were cut to estimate the productivity. The experiments were set in randomized blocks design with four replicates. The cane stalk yields in the first cut were higher in the treatment with two both N sources (organic and mineral), however not differing between them. The highest fertilizer contributions on nitrogen to sugarcane crop were observed eight months after sugarcane planting for treatments containing green manure without mineral N, and green manure with mineral N. The largest nitrogen recovery was observed during the first harvest, 18 months after planting: 34.4% in the treatment containing mineral fertilizer and 40.0% in the mineral N plus green manure N treatment. It more nitrogen in the sugar cane ratoon was originated from the green manure treatment 4.8%, while only 1.7% was observed in mineral N source. The presence of green manure crop and mineral N applied together promoting increases in Ca and Mg contents, Sum of Bases, pH, and Base Saturation, with a decline in potential acidity.
Increased Susceptibility to,-Lactam Antibiotics and Porin Content Caused by envB Mutations of Salmonella typhimurium Decreased

Field: Immunology and Microbiology (Life Sciences)

Isogenic derivatives carrying envB6, envB9, or envB+ alleles were obtained from a strain of Salmonella typhimurium that was partially resistant to mecillinam, a I-lactam antibiotic specific for penicillin-binding protein 2 (PBP 2). Testing of the isogenic strains with several antibacterial agents demonstrated that envB mutations either increased resistance (mecillinam) or did not affect the response (imipemen) to,B-lactams that act primarily on PBP 2, while susceptibilities to P-lactams that act on PBP 1B, PBP 3, or both were increased. Furthermore, the susceptibilities of envB sttains to hydrophobic compounds such as rifampin, novobiocin, or chloramphenicol were not modified, even though their susceptibilities to deoxycholate and crystal violet were enhanced. Outer cell membranes ofenvB mutants presented a 50 % reduction in protein content compared with that of the isogenic envB+ strains, and OmpF and OmpD porins were particularly affected by the reduction. No alteration in the amount or pattern of periplagmic proteins was noticed, and lipopolysaccharides from envB mutants appeared to be normal by sodium dodecyl sulfate-urea-polyacrylamide gel electrophoresis. By using derivatives that produced a plasmid-encoded,B-lactamase, it was demonstrated that envB cells are slightly less permeable to cephalothin than envB+ bacteria are. It is concluded that the high susceptibility of envB mutants to j-lactams is due to the increased effectiveness of the antibiotics on PBP 1B, PBP 3, or both. The action of 3-lactam antibiotics on enterobacteria is
Addenda from pre-Meninski transcription texts to Stanisław Stachowski’s “Osmanlı Türkçesinde Yeni Farsça Alıntılar Sözlüğü”. Part V

Field: Arts and Humanities (Social Sciences)

Stanisław Stachowski wrote a series of articles devoted to studies on the New Persian loanwords in Ottoman-Turkish, which were published in ‘Folia Orientalia’ in the 1970s and later republished in 1998 as a single volume. Since then, however, a good number of editions of new Ottoman texts have appeared, especially transcription texts dating from before Meninski’s Thesaurus (1680), which provide much new lexical material. Within this material there are many Persianisms ‒ predictaby enough where Ottoman-Turkish is concerned. This paper aims to supplement Stachowski’s work with words of Persian origin taken from pre-Meninski transcription texts. It is divided into two parts, the first including data to be added to entries already recorded by Stachowski (eight articles), the second containing data that constitute new entries (three articles). A short historical-etymological note on the words dealt with also features at the end of each entry.
A journey's notes

Field: Arts and Humanities (Social Sciences)

Wilfred Bion first landed in our midst in 1967, invited by Frank Philips, one of the founders of the Sao Paulo Society, who had earlier trained in London and undergone analysis with both Klein and Bion. Our colleagues are unanimous in describing the profound impression this British psychoanalyst had upon our analytic milieu and the deep impact of his thought on the Brazilian Psychoanalytic Society of São Paulo. Almost immediately, his work came to predominate over the classical Kleinianism that had preceded it, offering a breath of innovation and stimulating ever deeper studies into the psyche and the analytic process. This situation lasted to the end of the 1980s, when its supremacy began to be questioned and was followed by an opening to other schools of thought and to a renewed interest in Freud's work. Bion, however, never ceased to be studied—and I believe it is no exaggeration to assert that to date his writings are one of the identifying marks of the São Paulo Society. The work of a great author instigates new intellectual adventures for those who investigate it—and this book bears witness to one of the products of this shared trajectory.
Assessment of the Doppler Effect on Transmission Characteristics in LEO Satellite Networks

Field: Computer Science (Physical Sciences)

Laser-based inter-satellite links for LEO satellite networking are a promising technique for future 6G networks. However, the variable high-speed relative motion of LEO satellites results in time-variable Doppler shifts at different locations. In this paper, we derive and simulate the Doppler shifts in detail at different locations within the LEO satellite network and analyze their effects on the network characteristics.
The Performance Evaluation of SMA Spring as Actuator for Gripping Manipulation

Field: Engineering (Physical Sciences)

This paper is to present the evaluation of a TiNi Shape Memory Alloy (SMA) spring as actuator for the gripping manipulation.The SMA spring employed was a TiNi tensile spring which has a diameter of 50 mm wire and 350 gram hanging mass.The gripper fabricated consists of two fingers and each finger is actuated by the SMA spring.The total angular displacement of the gripper is 30 0 .The power consumptions, the movements and force generations experimentations have been conducted.The DC signal and PWM signal with 12, 12Hz, 25Hz, 125Hz, 250Hz and the 1150Hz have been employed for driving the SMA.The experimental results indicated that the 125Hz of PWM signal was likely to be had a better performance than the other signals.The 125Hz PWM signal generated faster movement, lower power consumption, and constant rate of force.In this study, closed-loop control for gripping manipulation was also conducted.The close loop controller used is PID controller.The Ziegler-Nichols method has been used to predict the optimal gain of the controller, but the best performance was determined by experimentally tuning of the gains.The experimental results indicated that the PID controller is likely to be reliable controller for gripping manipulation of the SMA spring.To obtain the better performance, it is important to consider the SMA cooling responses and the long time of retain in certain position of the gripper.
Stability of texture and shape of circular domains of Langmuir monolayers

Field: Physics and Astronomy (Physical Sciences)

Finite domains of a Langmuir monolayer in a phase with tilted molecules can\nbe modeled by a simple elastic free energy of an XY order parameter with\nisotropic and anisotropic line tension terms. The domains can and often do\ncontain nontrivial textures, which in turn influence the shape of the domains.\nHerein we investigate the properties of a simplified isotropic model with a\nsingle elastic constant. For circular domains a first-order phase transition is\nfound between two distinct textures: an exterior defect (or ``virtual boojum'')\ntexture, and an interior defect texture. Starting with a circular domain and\neither of these two textures as a ground state, we find shape instabilities\ndevelop that depend on the elastic constants and line tensions in the\nsimplified model. In both cases a necessary but not sufficient condition for\nthe onset of shape instabilities is the possibility for a local negative\neffective line tension to develop from the anisotropic line tension term.\n
Cephalic Phase of Insulin Secretion in Obese Women

Field: Medicine (Health Sciences)

The cephalic phase of reflex insulin secretion was studied in normoglycemic and normoinsulinemic female patients, obese (more than 30% over IBW) and normal subjects. After an overnight fasting, at the sight of breakfast food, the obese group did not present a cephalic response. Their glycemia and insulinemia levels remained at base levels. One minute after visual and olfactory stimulation, a statistically significant rise in immunoreactive insulin levels which was maintained throughout the test, was observed in the control group.

Abstract Objective: to analyze the frequency and associated risk factors for COVID-19 infection and the availability of Personal Protective Equipment used by primary healthcare workers. Method: a cross-sectional study was conducted over six months in Rio Grande do Sul. Descriptive analysis was performed, with the comparison of independent samples using Pearson’s Chi-square test and Fisher’s Exact test (p<.05). Results: the study included 206 (27%) healthcare workers who presented COVID-19 symptoms. There was a statistical association for the following variables: availability of surgical masks (p=.003), seeking information on the correct use of personal protective equipment (p=.045), having attended people with flu-like syndrome (p=.024), and believing that the highest risk of contamination is when attending a patient positive for coronavirus disease (p=.001). Conclusion: the availability of personal protective equipment is indispensable for COVID-19 prevention, with special emphasis on the use of surgical masks. Furthermore, the study highlighted the importance of providing Personal Protective Equipment in conjunction with guidance on its use.
Novel Coupled-Inductor Multi-phase VRs

Field: Engineering (Physical Sciences)

Coupling the output inductors of the multi-phase Buck can reduce the steady-state current ripple while maintaining the same transient response. The conduction losses in the switches can thus be reduced. Furthermore, using coupled inductor can greatly improve the dynamic performance with smaller inductance during the transient. Magnetic fundamentals of the existing coupled inductor multi-phase Buck converters will be revealed in this paper firstly. With the insight gained, novel coupled inductor circuitries will be disclosed. They feature flexibility, symmetric magnetic path, short winding length, and light load efficiency enhancement. Finally, theoretical analysis, design guideline and experimental verification are included.
Addressing Body Image After Reconstructive Surgery in Adult Patients with Cancer

Field: Nursing (Health Sciences)

Body image or how a person views their body and the way it functions ultimately influences their quality of life and functional well-being in their daily environments. The changes to appearance or to body structures and functions that occur as a result of cancer and its treatment can cause individuals to become dissatisfied with their body image where maladaptive emotions, thought processes, and behaviors develop and may lead to deleterious consequences including social avoidance and isolation. Although reconstructive surgery is restorative in nature, it does not guarantee the mitigation of body image dissatisfaction when treating adults with cancer. The majority of adults who undergo reconstructive surgery for the treatment of cancer demonstrate some level of body image dissatisfaction during or after the reconstructive process. Therefore, a need exists for nurses and other oncological team members to recognize and address body image dissatisfaction and the detrimental emotional and behavioral consequences associated with it. This article provides guidance for nurses to address body image by understanding the effects of cancer and its treatment on body image, by recognizing the impact of reconstructive surgery on body image when treating cancer in adults, and by integrating body image assessment and interventions into practice.
Food Safety Knowledge and Attitudes: A Cross-Sectional Study among Saudi Consumers from Food Trucks Owned by Productive Families

Field: Health Professions (Health Sciences)

Food businesses, such as food trucks (FTs) and family producers have grown rapidly and become popular with people in Saudi Arabia. As foodborne diseases are still a public health concern in the country, consumers should be aware of the safety of foods sold by food trucks. Since there is a dearth of literature, this study aimed to assess the knowledge and attitudes of consumers of food from FTs owned by family producers regarding food safety and foodborne disease. A cross-sectional study was conducted among 921 consumers of food from FTs from two cities in the southern region of Saudi Arabia. Data were collected using an online questionnaire from September to November 2021. Finally, multiple linear regression and a logistic regression model were used to identify the predictors of knowledge and attitude regarding food safety and foodborne illness, respectively. Overall, respondents had moderate knowledge and higher positive attitudes regarding food safety and foodborne illness. Respondents’ knowledge about the potential harm and attitudes towards the safety of foods sold by FTs were significantly associated with marital status, education level, and monthly family income. The findings of this study highlight the need to improve the knowledge, awareness, and attitudes of Saudi consumers of food from FTs owned by family producers on food safety and foodborne illness through intervention programs, particularly targeting consumers with lower educational attainments and income status, to control foodborne diseases.
Molecular genetics and the transformation of clinical chemistry.

Field: Medicine (Health Sciences)

Abstract Clinical chemistry is going through an identity crisis, squeezed between automation (de-skilling) on the service side and molecular genetics in research. Automated routine estimations are now carried out and interpreted by machines; the skilled staff members required are more likely to have degrees in electronics than medicine or biochemistry. The role of molecular genetics is more ambiguous; it is inherently reductionist, in that it attempts to explain most clinical phenomena in terms of DNA sequence alone. This has been remarkably successful for single-gene defects (such as those causing Duchenne muscular dystrophy, hemoglobinopathies, cystic fibrosis, and ataxias) and may well prove equally so for Alzheimer's disease, cancer, heart disease, and schizophrenia. DNA diagnosis is not yet routine, but because of technical advances such as gene amplification ("PCR") and high-sensitivity gene-detection assays, it may soon become so, not only in major centers but also in local pathology laboratories and general practice. Clinical chemists must decide whether they wish to respond to this new and stimulating challenge by retooling and retraining. Should anyone be permitted into clinical chemistry during the 1990s without knowledge of both electronics and molecular genetics? Will there be a clinical chemistry in the twenty-first century other than through molecular genetics? This article is a personal response to these questions.
Modal Test and Model Modification of the Rotating Parts of a Self-propelled Antiaircraft Gun

Field: Engineering (Physical Sciences)

Abstract The rotating parts of a self-propelled antiaircraft gun is taken as the research object, the single point excitation and multi-point response frequency response function method were used to test the experimental mode. At the same time, the finite element simulation model is established, and the frequency and mode of vibration are obtained. Combined with the modal test and analysis of the rotating parts, the stiffness of the connection between the rotating parts and the turret is selected as the optimization parameter. The numerical simulation model was optimized and modified by comparing the experimental and simulation modes and combining with the sensitivity analysis of the connection parameters, the correction variable with the higher sensitivity of the parameters to the results was selected. After optimization, the error between the first order calculation frequency and the test frequency is reduced from 8.61% to 1.13%, it is shown that the simulation model optimized by parameters can better reflect the physical characteristics of the real structure.
