Abstract
In this paper, a design methodology for a miniaturized millimeter-wave bandpass filter (BPF) on-chip is presented. The introduced method is based on quasi-lumped elements, which consist of a resonator with a meander transmission line and metal-insulator-metal (MIM) capacitors. In this technique, the conventional large-size coil is replaced by a compact transmission line and MIM capacitor, where the filter is equivalent to the large coil and the associated capacitors. Four implementations of simplified LC-equivalent circuit layouts are carried out in order to fully explain the introduced technique. The four introduced designs are first-order Butterworth BPF, second-order Butterworth BPF, third-order Butterworth BPF, and fourth-order Butterworth BPF. All these four designs are simulated in 0.13-µm BiCMOS technology. Each of the first design BPF and the second BPF has one meander line and MIM capacitors (one capacitor in first design and two capacitors in second design). The simulation results for the first design BPF show an insertion loss of 2.3 dB at the frequency center of 54.2 GHz of this filter, and the return loss range from 10 dB to 28.3 dB in the band of frequencies of 48.9 to 58.9 GHz. The chip size of the first design BPF is 0.055 × 0.074 mm2. The simulation results for the second design BPF show an insertion loss of 2.37 dB at the frequency center of 47.5 GHz of this filter, and the return loss range from 10 dB to 23 dB in the band of frequencies of 44 to 53 GHz. The chip size of the second design BPF is 0.092 × 0.074 mm2. The third design BPF and the fourth design BPF include two meander lines and MIM capacitors (three capacitors in third design and four capacitors in fourth design), which has a very low insertion loss of 1.19 dB at the frequency center of 49 GHz. The return loss ranges from 10 dB to 45.3 dB at frequencies 41 GHz to 59 GHz. The chip size of the third design BPF is 0.098 × 0.19 mm2. The simulated results for the fourth-design BPF show an insertion loss of 1.25 dB at the center frequency of 50 GHz, and the return loss ranges from 10 dB to 50 dB at frequencies from 43 GHz to 58 GHz. The chip size of the fourth BPF is 0.098 × 0.25 mm2. The bandwidth range for each of the four designs is 48.2 GHz to 59.3 GHz for the first BPF, 44 GHz to 53 GHz for the second BPF, 35 GHz to 65 GHz for the third BPF, and 38.5 GHz to 64 GHz for the fourth BPF.

Abstract
Low-load resistance training with blood flow restriction (LL-BFR) has been shown to be an effective method for increasing strength and muscle size like high-load exercise (HL); however, perceptual and affective responses to LL-BFR with different arterial occlusion pressure (AOP) have rarely been investigated. The study aimed to investigate the effects of manipulation of restriction pressure with LL-BFR on psychophysiological responses and to compare with HL. Twenty-two resistance-trained men performed LL-BFR at 20% 1RM with 40% (20/40), 80% (20/80) and 120% (20/120) AOP and 70% 1RM in a crossover design. Participants performed 20/40, 20/80 and 20/120 protocols in four sets of 15 repetitions of unilateral elbow flexion exercise, with 1-min rest, with a pressure cuff placed around the proximal region of the dominant arm, while 70/0 was performed in four sets of 10 repetitions, with 90 s rest. The rating of perceived exertion (RPE) and perceived pain (PP) were assessed at the end of each set, while perceived affect (PA) was assessed immediately after the exercise session. The RPE in 70/0 (ES: 1.6) was significantly higher than all protocols in the first set (p<.0001) and similar to 20/120 in the 2, 3, and 4 sets (ES: 5.4) (p>0.05). RPE increased dose‒response with BFR: 20/40 ES: 1.2, and 20/80 ES: 1.9 (p<.0001). Protocols 20/120 and 20/80 significantly induced greater PP and lower PA compared to the 20/40 and 70/0 protocols (p<.0001). Higher levels of restriction pressure promote a greater sensation of pain and exertion, which can impair adherence for new participants. Keywords:

Abstract
In February 2023, seedlings of wax gourd (Benincasa hispida (Thunb.) Cogn.) developed water-soaked rot on hypocotyls in the seedling period in Japan. The diseased seedlings eventually displayed damping-off. A Pythium sp. was isolated from the hypocotyls and was identified as Pythium aphanidermatum based on the morphological characteristics and internal transcribed spacers region of DNA sequences. The same symptoms were observed when seedlings were inoculated with the isolated fungus. Moreover, the same fungus was reisolated from the damping-off seedlings. This is the first report of damping-off in wax gourd seedlings caused by P. aphanidermatum during the seedling period in Japan.
The City as a Metaphor for Order: The Prohibition on the Sale of Alcoholic Beverages at Night as a Means of Purifying Public Space
Authors: Vukićević Jelena 
Published: July 2023

This paper discusses a segment of a study that took place between 2012 and 2015, which examined the then-existing ban on the sale of alcoholic beverages in commercial establishments at night in several Serbian cities, including Belgrade, Kragujevac, Novi Sad, Šabac, and Zrenjanin. The research also looked at how the media represented the ban from 2006 to 2013 and analysed data obtained through a questionnaire completed by 22 individuals from Belgrade in 2023.
The study examined various aspects of the ban, including its role in the context of spatial power operation, which is discussed in this paper. The researcher began with the assumption that the ban on the sale of alcoholic beverages at night in commercial establishments could be interpreted as a way of purifying public space, through which one social group establishes dominance over others in society by controlling public space. This is achieved not only by excluding members of specific social groups from the specified place, but also by excluding socially inappropriate practices deemed typical for those groups. The ultimate goal is to organise public space so that it reflects dominant societal values and achieves dominance for the group that tends to represent those values.
The restriction was seen to be targeted at preventing members of the lower classes and young people, as members of the aforementioned classes, from occupying public space. It also had the broader aim of prohibiting the purchase and problematic use of alcoholic beverages late at night, a practice identified in the aforementioned socioeconomic strata, where it was perceived as a possible source of disruption, violence, and a threat to upper-class citizens. The decision was an attempt to increase the safety of the higher classes by limiting the ability of members of the lower classes and youth to purchase alcoholic beverages at night, as well as through spatial segregation. Although not explicitly stated, one of the effects sought by this decision was the prohibition of alcohol consumption in public places among the aforementioned social groups.
The purpose was to instil a sense of security in the community and to project an image of moral order in society. It represented a mechanism for the higher classes to assert their authority in society and to establish their class identity by spatially separating themselves from the classes with which they were placed in a relationship of opposition. Thus, public space was created to reflect the values advocated by upper-class citizens, such as order, self-control, moderation, and decency, which aided their dominance in society.
Correlation between Si-Al disorder and hydrogen-bonding distance variation in ussingite (Na2AlSi3O8OH) revealed by one- and two-dimensional multi-nuclear NMR and first-principles calculation
Authors: Xue Xianyu , Kanzaki Masami 
Published: July 2023

Abstract
Ussingite (Na2AlSi3O8OH) is a mineral with a unique interrupted framework structure and strong hydrogen bonding. It contains 4-, 6-, and 8-membered tetrahedral rings resembling feldspars, but, unlike the latter, is partially depolymerized. There are four crystallographically distinct tetrahedral (T) sites, two of which (T1, T2) are Q4 [i.e., having 4 next nearest neighbor (NNN) T sites], and the other two (T3, T4) are Q3 (i.e., having 3 NNN T sites), each with NNN (in brackets) of T1(1T2, 1T3, 2T4), T2(1T1, 2T3, 1T4), T3(1T1, 2T2), and T4(2T1, 1T2). There is one unique OH site in the T4-O8-H···O2-T3 configuration, where O8 and O2 are nonbridging O atoms (NBO). In the ordered structure, T1 is fully occupied by Al, and the other three T sites by Si. Previous X-ray and neutron diffraction and 1H and 29Si NMR studies gave contradictory conclusions regarding Si-Al disorder. In this study, we were able to unambiguously clarify the issue via comprehensive one- and two-dimensional 1H, 29Si, 27Al, and 23Na NMR and first-principles calculation. It was revealed that there is ~3% Si-Al disorder that occurs between neighboring T1-(O)-T2 sites, such that the formation of Al-O-Al linkage and Al(Q3) are avoided. The disorder was found to result in the development of Si(Q3) sites with various NNN, including 3Al and 3Si, and neighboring OH sites having significantly shorter and longer hydrogen-bonding distances than in the ordered structure, with 1H chemical shifts near 15~16 ppm and 11 ppm, in addition to a main peak near 13.9 ppm. Good correlation was found between 1H chemical shift, hydrogen-bonding (O-H, H···O, and O···O) distances, and Si-O distances in the Si-O-H···O-Si linkage. This suggests that Si-Al disorder is correlated with variation in hydrogen-bonding distances via through-bond transmission of bond valence variations. This could be a universal phenomenon also applicable to other hydrous minerals. The revelation of preferential partition of Al in Q4 over Q3 sites to avoid the formation of Al-OH and Al-NBO provides insight into their behavior in other partially depolymerized hydrous aluminosilicate systems, such as glasses and melts.

Abstract

Treatment of tunnel wash runoff water and road runoff water before it reaches the environment is recommended to limit the negative consequences of traffic-related pollution. The efficiency of existing water treatment systems to remove traffic-related microplastic (MP) has not been sufficiently documented. Expanding the knowledge about traffic-related MP and documenting the treatment efficiency of MP in road tunnel wash water (TWW) and road runoff (RRW) treatment systems were the objectives of the presented project. TWW from the Tåsen tunnel, Norway, and RRW from the Fossbekken sedimentation pond were investigated in summer and winter situations. Six commonly available polymer types, tire rubber tread particles (TRP), and road marking paints (RMP) were analyzed in the selected samples. About 0.12 and 0.26 μg/L of polymers were identified in winter and summer TWWs. Significantly higher tire rubber and road marking paint concentrations were identified in the winter sample compared to summer sample. Suspended particle concentration in the Fossbekken RRW treatment pond effluent was lower in the summer than in the winter sample. About 0.002 and 0.0008 μg/L polymer masses were identified in winter and summer samples, respectively. TRP in the winter and summer samples were 0.7 and 0.2 μg7/L, and 13.4 μg/L RMP was found in the winter sample, while it was only 0.008 μg/L in the summer sample.

Abstract

Urban cloudburst management may include the intentional temporary storage of flood water in green recreational areas. In cities with combined sewers, this will expose the population visiting the area to sewage and increase the risk of diarrhoeal disease. We present a unique approach to estimate the risk of diarrhoeal disease after urban flooding. The exposure scenario was: rainwater mixed with sewage flows into a park; sewage with pathogens deposit on the grass; after discharge, a baby plays on the grass and is exposed to the pathogens in the deposited sewage by hand-to-mouth transfer. The work included modelling the transport of sewage into four parks intended to be flooded during future cloudbursts. A flood simulation experiment was conducted to estimate the deposition of pathogens from sewage to grass and transfer from grass to hand. Hand-to-mouth transfer, based on literature values, was used to estimate the ingested dose of pathogens. The probability of illness was estimated by QMRA. The estimated average probability of illness varied between 0.03 and 17%. If the probability of illness is considered unacceptable, the cloudburst plans should be changed, or interventions, e.g. informing the public about the risk or restricting access to the flooded area, should be implemented.

Published: July 2023

Background:
In recent times, modifying dietary habits to control cardiovascular risk factors has
gained significant attention. However, previous studies have yielded inconsistent results regarding the effects of
lycopene and tomato consumption on cardiovascular risk factors.

Objective:
The objective of this study was to assess the impact of consuming lycopene and tomatoes on various
cardiovascular risks factors such as lipid profile, glycemic control markers, blood pressure, inflammation, oxidative
stress, and body weight.

Methods:
A systematic literature search was carried out using electronic databases, including PubMed, Web of
Science, and Scopus, up to November 2022 to identify eligible Randomized Control Trials (RCTs) evaluating
the effect of lycopene and tomato consumption on cardiovascular risk factors. Heterogeneity tests of the selected
trials were performed using the I2 statistic. Random effects models were assessed based on the heterogeneity
tests, and pooled data were determined as the weighted mean difference (WMD) with a 95% confidence interval
(CI).

Results:
Out of 27,438 records initially identified, a total of 34 studies met the eligibility criteria and were included
in this meta-analysis. The results showed that lycopene consumption was associated with a significant
reduction in malondialdehyde (MDA) levels, indicating a potential benefit in reducing oxidative stress. However,
lycopene and tomato consumption did not have significant effects on other cardiovascular risk factors such
as triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein
cholesterol (HDL-C), fasting blood glucose (FBG), systolic blood pressure (SBP), diastolic blood pressure
(DBP), Intercellular Adhesion Molecule 1 (ICAM-1), c-reactive protein (CRP), interleukin 6 (IL-6), tumor necrosis
factor α (TNF-α), body weight, and body mass index (BMI).

Conclusion:
Overall, the findings showed that lycopene and tomato consumption did not affect cardiovascular
risk factors. However, lycopene supplementation may result in a significant improvement in MDA levels. With
the view to confirming these results, further studies with long-term duration and different doses are needed.

Published: July 2023

Background:
A lot of work has been done by many researchers to develop a system that is
targeted at a specific site. Nanosponges are one of the systems that serve this purpose and have several
advantages over other methods.

Objective:
The article’s strategy is to provide access to data regarding the nanosponges system, including
its preparation, evaluation, and advantages in various fields, such as the transportation of proteins,
vaccines, biocatalysts, and drugs with enhanced bioavailability. Nanosponges also contribute
significantly to the treatment of breast cancer, lung cancer, fungal infection, water treatment, and topical
application than other approaches.

Method:
Nanosponges contain a solid, porous system in which hydrophilic or lipophilic drugs are
loaded at their core in the nanocavity. All the information provided in this article was collected after
analysing various reports on nanosponges available on Google Scholar, PubMed, Scopus, Web of Science,
and Science Direct. It is concluded that the nanosponges have excellent aqueous solubility properties.
Therefore, they can be used as carriers for drugs with poor water solubility. Moreover, greater
bioavailability can be achieved by using the nanosponge approach.

Conclusion:
Nanosponges possess various outstanding properties that form the unique system of this
approach. Nanosponges provide an effective carrier system for enzymes, proteins, vaccines, and therapeutic
fields. This review provides a broad overview of the development of nanosponges, their evaluation,
and the uses of nanosponges based on cyclodextrin for drug delivery.
Alumina Crucibles from Free Dispersant Suspensions: A Useful Labware
to form Advanced Powders for Radiation Dosimetry
Authors: S.C. Santos , A.S. Martins , T.L. Araújo , O. Rodrigues Jr , L.L. Campos 
Published: July 2023

Background:
Powder technology provides conditions to control particle-particle interactions
that drive the formation of final-component/material, which also includes the crystalline
structure, microstructure and features. Alumina (Al2O3) is the most studied ceramic based material
due to its useful properties, disposal, competitive price, and wide technological applicability.
This work aims to produce alumina crucibles with controlled size and shape from free dispensant
suspensions. These crucibles will be used as containers for the synthesis of new materials for radiation
dosimetry.

Methods:
The Al2O3 powders were characterized by XRD, SEM, PCS, and EPR. The stability of
alumina particles in aqueous solvent was evaluated by zeta potential determination as a function
of pH. Alumina suspensions with 30 vol% were shaped by slip casting in plaster molds, followed
by sintering at 1600oC for 2 h in an air atmosphere. Alumina based crucibles were characterized
by SEM and XRD.

Results:
ɑ-Al2O3 powders exhibited a mean particle diameter size (d50) of 983nm. Besides, the
stability of particles in aqueous solvent was achieved at a range of pH from 2.0-6.0, and from
8.5-11.0. EPR spectra revealed two resonance peaks P1 and P2, with g-values of 2.0004 and
2.0022, respectively. The as-sintered ɑ-alumina based crucibles presented uniform shape and
controlled size with no apparent defects. In addition, the final microstructure driven by solid-state
sintering revealed a dense surface and uniform distribution of grains.

Conclusion:
The ɑ-Al2O3 crucibles obtained by slip casting of free dispensant alumina suspensions,
followed by sintering, exhibited mechanical strength, and controlled shape and size. These
crucibles will be useful labwares for the synthesis of new materials for radiation dosimetry.

Background Antibody-based serological tests which target households and communities can estimate the true extent of infection in a population. It minimizes the biases of facility-based selective testing and generates scientific data on disease transmission through household asymptomatic cases. The objective of this study was to determine the seroprevalence and trend of SARS-CoV-2 in a densely populated urban community of Karachi. Methods Three serial cross-sectional surveys were conducted in November 2020, February 2021, and December 2021 in Karachi’s District East. Households were selected to provide serum samples for Elecsys® immunoassay for the detection of SARS-CoV-2 antibodies. All household members were eligible to participate regardless of age and infection status. Bayesian regression was used to adjust for assay performance and estimate seroprevalence. Results We enrolled 1506 participants from 501 households. In November 2020, adjusted seroprevalence was estimated as 24.0% (95% confidence interval, CI=18.0-31.0), compared to 53.9% (95% CI=45.5-63.2) in February. In December 2021, it increased to 84.9% (95% CI=78.5-92.3). The conditional risk of infection was 41% (95% CI=29.9-51.6), 56.7% (95% CI=50.4–62.6) and 77.8% (95% CI=73.0-81.7) in surveys 4, 5, and 6 respectively. Only 18.7% of participants who had reactive antibodies for COVID-19 were symptomatic. Conclusions An increase in seroprevalence estimates in Karachi’s District East was observed over time. Community-based seroprevalence studies help to estimate the true proportion of the population that has been infected and predicts the spread of the disease in similar settings.
