Changes in pH and Total Acidity of Sweetpotatoes Exposed to Wet, Cold Soil Conditions Before Harvest1
Authors: Kushman L. J. , Pope D. T.
Published: August 2022

Changes in pH and total acidity, comparable to those that occur in chilled roots during storage, take place in the field while the roots are still in the ground if wet, cold, soil conditions develop.
Evaluation of Activated Carbon Root Dichlobenil Toxicity Dips for Control of in Nursery Plantings1
Authors: MacCubbin Thomas J. , Link Conrad B.
Published: August 2022

Field studies conducted during 1967 and 1968 evaluated activated carbon as an adsorbent for the reduction of dichlobenil (2, 6-dichlorobenzitrile) plant toxicity occurring in newly established nursery plantings. Eight lb. per acre of dichlobenil was a critical level for plant toxicity control through root dips of activated carbon since visual injury was often pronounced where dichlobenil was increased above this rate. Increases in the activated carbon dip concn did not enhance plant protection. Activated carbon dips are most effective where herbicide injury is expected to be marginal and when residues will rapidly dissipate from the soil immediately surrounding a plant’s developing root system.
2-Chloroethylphosphonic Acid as an Aid to Mechanical Harvesting of English Walnuts1,2
Authors: Martin George C.
Published: August 2022

Spray application of 2-chloroethylphosphonic acid (ethephon) to walnut trees caused dehiscence of hulls and enabled complete nut removal with a single mechanical shaking operation as much as 3 weeks earlier than normal. Walnuts were hullable and the quality was generally superior to that of the controls. In some instances considerable leaf fall resulted from the treatment.
Cross-Feeding of Applied Fertilizer by Potato Plants from Adjacent Rows1
Authors: Emmond G. S.
Published: August 2022

Soil NO3-N levels and root distribution patterns suggested that cross-feeding of NO3-N by potatoes in adjacent rows may occur at row spacings of 3 and even 4 feet under irrigated conditions. Yields showed that sufficient cross-feeding occurred to significantly increase yields at a row spacing of 2 feet when low or medium amounts of fertilizer were applied and at a row spacing of 3 feet when a high amount of fertilizer was applied. Cross-feeding of phosphate fertilizer was limited to a row spacing of one foot.
Production of Ethanol, Acetaldehyde, and Methanol by Intact Oranges During and After Nitrogen Storage1
Authors: Norman S. M. , Craft C. C.
Published: August 2022

Endogenous volatiles emanating from intact navel oranges were measured by gas chromatography during and after N2 storage. The longer the oranges were held in N2 the greater was the rate of volatile production, both in N2 and after the fruit were returned to air. Ethanol was the predominant volatile emanating from oranges during N2 storage. The rate of ethanol production progressively increased in N2 storage and decreased when the oranges were returned to air. The rate of acetaldehyde production increased slightly in N2 storage and increased markedly to a maximum 2 to 4 hr after the oranges were returned to air, and then rapidly declined. The rate of methanol production increased in N2 storage and declined slightly when the oranges were returned to air. Oranges held 2 hr in N2 returned to pre-treatment volatile production rates after several days in air but those held for longer periods in N2 did not return to pre-treatment rates. All oranges held in N2 20 hr at 38° C or 3 or more days at 20° developed rind injury after the fruits were returned to air.
Growth Responses of Ground Cover Plants to Varied pH in Nutrient Culture1
Authors: Eggens J. L. , Hilton R. J.
Published: August 2022

Rooted cuttings of Anthemis nobilis, Arctostaphylos uva-ursi; Veronica officinalis and Houttuynia cordata were grown in the greenhouse and in nutrient solutions differing only in pH. The levels of pH were adjusted to 3 to 9 for A. nobilis and A. uva-ursi, to pH 4 to 9 for V. officinalis and to pH 4 to 6 for H. cordata. A. nobilis grew well at pH 4 to 7 but best growth was near pH 5. Arctostaphylos uva-ursi made best growth at pH 4 but not significantly better than at pH 5 to 7. V. officinalis grew well over a wide pH range (4 to 7 inclusive) and plants died gradually at pH 9. For the H. cordata trial a limited number of plants was available and at the imposed pH levels (4, 5 and 6) all plants grew uniformly and well.
Effects of Solar Radiation, Carbon Dioxide, and Soil Fertilization on Rosa hybrida1
Authors: Mattson Richard H. , Widmer Richard E.
Published: August 2022

Cut flower yield of four greenhouse rose cultivars was primarily influenced by solar radiation, while atmospheric CO2, air temperature, and soil nutrient levels were of lesser importance. Cultivars responded differently to atmospheric CO2 level and soil fertilization method. Roses fertilized with 20-20-20 in solution produced equivalent or greater flower yields than roses fertilized with 10-10-10 in dry form. Roses grown in CO2 enriched atmospheres did not require additional soil fertilization.

Regression coefficients and yield prediction equations were determined using nine environmental parameters. Monthly yield predictions were generally reliable, but cropping cycles and cultural practices decreased accuracy.
Year ‘Round Effects of Carbon Dioxide Supplemented Atmospheres on Greenhouse Rose (Rosa hybrida) Production1
Authors: Mattson Richard H. , Widmer Richard E.
Published: August 2022

Four Rosa hybrida cultivars were grown in 100 to 500, 700 to 1300, and 1500 to 2500 ppm CO2 atmospheres for at least half the daylight hours from November to May. Production was studied continually for 24 months.

Numbers of flowering stems and lateral buds, fresh weight, and stem length were greater in CO2 supplemented atmospheres on hybrid tea and floribunda roses. Non-flowering percentages were lower for floribundas in CO2 enriched atmospheres. Greater leaf abscission and less root development were noted for hybrid tea and floribunda roses in 1500 to 2500 ppm CO2. Higher yields in non-CO2 supplementation periods (May to October) largely reflected growing conditions rather than CO2 effects.
The Nutritive Composition of Pea and Sweet Corn Seeds as Influenced by s-Triazine Compounds1,2
Authors: Salunkhe D. K. , Wu M. T. , Singh B.
Published: August 2022

The results of 2 years’ field trials indicate that application to the soil of s-triazines, including simazine, propazine, igran, and ametryne, at low concentrations (0.125 and 0.5 lb./A) increased the protein content of pea (Pisum sativum L., cv. Perfected Freezer) seeds. Relatively higher concentrations (1 and 4 lb./A) of simazine, atrazine, prometone, igran, or ametryne were needed to increase the protein content of sweet corn (Zea mays L., cv. Iochief) seeds. Both quantitative and qualitative changes were noted in the pattern of amino acids in the seeds from the treated plants.
Flowering and Fertility Changes in Six Generations of Open Pollinated Sweetpotatoes1
Authors: Martin Franklin W. , Jones Alfred
Published: August 2022

The fertility of 6 successive generations of open pollinated sweetpotatoes was studied in each of 4 months. Breeding by open pollination increased the percentages of plants in flower, the number of flowers per plant, and total seed production. Both capsule and seed numbers per flower were higher in the first and last generations than in intervening generations. Self-compatibility, when determined by numbers of pollen tubes per stigma, was not affected by the breeding procedure. Mean numbers of pollen tubes per flower following cross pollination were higher in the later generations. Month to month effects were important in the case of all measurements. Flowering was most profuse in the middle of the season; seed set was highest early in the season; and pollen germination after selfing or crossing was highest at the beginning and end of the season.
Rest Period Reduction in Non-Stored Onion (Allium cepa L.) Sets
Authors: Hopen H. J. , Dedolph R. R. , Whiteside W. F. , Chorney W.
Published: August 2022

Rest period reduction in non-stored onion (Allium cepa L.) sets is favored by post-harvest temperatures of 5° and 25°C for periods of 1 to 10 days. A short-term post-harvest temperature of 45°C favored rest period reduction, but periods over 24 hr at 45° did not reduce the rest period. Reduction of sprouting attributable to the 45° storage was more pronounced with the White Portugal cultivar than with Yellow Ebenezer. Zero to 800 rad gamma irradiation (of freshly harvested sets) did not influence time of sprouting but doses from 1,600 to 12,800 rad decreased sprouting. Potassium gibberellate (A3)(applied as a dip treatment on sets) increased weights of plants grown from sets stored at 5°C for 72 hr before planting. High post-harvest storage temperatures (45°) negated the subsequent growth promoting effects of GA. Application of these findings has resulted in commercial shipments of freshly harvested onion sets under refrigeration.
Heating Seedlings of Normal, Cytosterile and Restored-Sterile Corn and its Effect on Pollen Production1
Authors: Lachman W. H.
Published: August 2022

Plants of sweet corn from germinated seeds treated at sub-lethal temperatures were less vigorous and shorter than their controls. The pollen shedding patterns of plants from normal Cl3, T-sterile Cl3 and restored-sterile sweet corn inbreds were not altered by the heat treatments. Pollen shedding patterns among several commercial sweet and field corn hybrids were also unaffected by the treatments. If a virus is responsible for cytoplasmic male sterility in corn it appears to be less sensitive to heat treatment than do the seedlings.
Floral Initiation, Development, and Associated Phenomena of Dianthus caryophyllus L. Part I - Effect of Photoperiod1
Authors: Cheng L. H. , Langhans R. W.
Published: August 2022

Dianthus caryophyllus L., a quantitative long day plant, was used for studies of the effect of photoperiod on the different stages of plant development. The anatomical structure of the vegetative shoot apex and the changes during floral transformation are described. These stages were not affected by the various photoperiod lengths, i.e., 9, 13, and 18 hr.

The developmental cycle of D. caryophyllus may be divided into 3 stages: vegetative, floral initiation, and floral development. The influence of photoperiod on the duration of each of the 3 stages was different. The length of the vegetative stage was inversely related to the length of the photoperiod (the longer the photoperiod, the shorter the vegetative stage). Daylength had no effect on the period of floral initiation, but did affect the period of floral development (i.e., the longer the photoperiod, the longer the developmental stage). The rate of stem elongation under all treatments increased exponentially until the floral initiation state, and then the plants grown under photoperiods of 13 hr or longer elongated significantly faster than those under the 9-hr photoperiod. After flower initiation was completed, the rate of stem elongation suddenly increased linearly until the flower opened. In contrast to the vegetative shoot, the rate of stem elongation of flowering plants was completely independent of photoperiod, and the rate was the same in the 9, 13, and 18 hr photoperiods.
Improved Methods for Breaking Rest in the Peach and Other Deciduous Fruit Species1
Authors: Erez A. , Lavee S. , Samish R. M.
Published: August 2022

The rest period of peach buds was broken by application of several compounds. DNOC-mineral oil, thiourea, aqueous DNOC, KNO3, gibberellic acid and kinetin were found to be active. Combinations of active compounds found to be most efficient were: DNOC-mineral oil + thiourea; DNOC-mineral oil + gibberellic acid; and KNO3 + thiourea. Potassium nitrate and kinetin mainly advanced flower bud opening, while thiourea had a more pronounced effect on leaf bud opening. Combinations of pairs of the 3 compounds, DNOC-mineral oil, thiourea and KNO3 were best for commercial use.

Authors: Lampe Craig , Watada Alley E.
Published: August 2022

The ripening rate of tomato fruit with high pigment and/or crimson characteristic was about the same as that with normal pigment; however, the lycopene content of the former fruit was much greater. Shelf life of fruit containing high pigment and crimson characteristic was significantly greater than that of other fruit. All fruit exhibited a typical climacteric in the respiration pattern.

Authors: Belov S. A. , Grigoryuk А. А.
Published: August 2022

The objective: to study the efficiency and effectiveness of various non-resection ways of pulmonary bleeding control in patients with disseminated fibrous cavernous pulmonary tuberculosis.Subjects and Methods. A retrospective non-randomized study of complex treatment of 68 patients with fibrous cavernous pulmonary tuberculosis was performed. All the patients received treatment from 2012 to 2020 and the course of their disease was complicated by grade 1 pulmonary bleeding.Results. The patients were divided into three groups depending on the treatment used. Patients in Group 1 (n = 16) underwent upper posterior thoracoplasty with a mesh implant; all patients (100%) had good results: hemostasis was stable, cavities were healed and there were positive changes in the course of tuberculosis. In Group 2 (n = 15) with valve bronchial block, good results were observed in 86.7% of patients. Patients in Group 3 (n = 37) received conservative treatment supplemented with pneumoperitoneum; a good result was noted in 43.2% of patients.

Published: August 2022

The objective: to identify promising directions for prevention of HIV incidence mortality on the basis of analysis of changes in HIV situation assessing the effectiveness of interventions in penitentiary units.HIV infection has traditionally been a critical issue for the penitentiary system worldwide and in Russia particularly. Recently, Russia has managed to achieve positive changes in the epidemic situation: by 2020, HIV incidence reduced to 852.8 per 100,000 (including 2,433.6 in remand prisons and 122.8 in correctional institutions); HIV prevalence was 10,512.8 per 100,000; HIV mortality was 98.3 per 100,000; HIV lethality was 0.9 per 100,000 people living with HIV.The proportion of HIV infection as a cause of death decreased from 32.0 in 2016 to 20.5 in 2020. The positive changes developed faster compared to civilian health care and occurred during the growing coverage with antiretroviral therapy which increased from 21.7% in 2014 to 89.6% in 2020. The following problems persist: high prevalence of HIV infection among female inmates (19,275.0 versus 9,769.2 among male inmates per 100,000), the high proportion of HIV/hepatitis C co-infection (49.0%; 95% CI 48.6-49.5), and the low coverage with hepatitis C treatment (0.5% of the total number of persons with co-infection). Promising directions for the prevention of HIV incidence and mortality are related to stable supply of antiretroviral drugs, improved patient adherence to treatment, and expanding treatment for HIV/hepatitis C co-infection.
Tuberculosis Situation in the Years of the COVID-19 Pandemic – 2020-2021
Authors: Vasilyeva I. A. , Testov V. V. , Sterlikov S. A.
Published: August 2022

The article presents the analysis of changes in preliminary and estimated epidemiological rates: tuberculosis (TB) incidence, TB mortality, and clinical and social structure of new TB cases. It has been found that against the background of continuing improvement of the epidemic situation (reduction of TB incidence and mortality), the clinical structure of TB cases detected in 2020-2021 deteriorated compared to 2015-2019 which was manifested by higher frequency of pulmonary tissue destruction, massive bacterial excretion (by smear), and fibrous cavernous pulmonary TB. The number of TB cases detected post mortem has increased, as well as one-year mortality. These changes indicate low detection of TB cases in 2020. Changes in the incidence of TB/HIV co-infection and the number of new cases with bacterial excretion and multiple drug resistant TB essentially repeat the changes in TB incidence in the resident population during this period.

Published: August 2022

Background: A dedicated trauma operation theatre (TOT) and a trauma intensive care unit (TICU) within the same block as the emergency department (ED) can facilitate immediate management and surgery of patients suffering from traumatic brain injury (TBI). The present study compared the effectiveness and outcomes of TBI management between the TOT-TICU and general OT (GOT) and neuro-ICU (NICU) setups. Methods: This was a retrospective cohort study involving 120 patients with TBI who were divided into the GOT-NICU (n = 63) and TOT-TICU (n = 57) groups. Data were obtained from patients’ admission and medical records. Demographic data, durations of specific management phases and outcomes of patients were documented. Results: In the TOT-TICU group, the duration of transportation from ED to OT [15 (standard deviation [SD] = 15) min versus 45 (SD = 15) min; P < 0.001], duration of arrival in OT to incision [50 (SD = 30) versus 70 (SD = 23) min; P = 0.005] and duration of transportation from OT to ICU [40 (SD = 17) versus 48 (SD = 30); P = 0.005] were significantly shorter than those in the GOT-NICU group. However, the duration of mechanical ventilation, duration of ICU stays, Glasgow Outcome Scale (GOS) upon discharge and GOS at 3-month post-discharge were comparable between both groups. Conclusion: The TOT-TICU setup shortened the duration of transportation from ED to OT, duration of arrival in OT to incision and duration of transportation from OT to ICU compared with the GOT-NICU setup. Hence, the availability of OT and ICU within the trauma block managed to provide immediate management to TBI patients.

Authors: Vandelli Matteo , Kaufmann Josef , El-Nabulsi Mohammed , Harkov Viktor , Lichtenstein Alexander , Stepanov Evgeny
Published: August 2022

We present the multi-band dual triply irreducible local expansion (D-TRILEX) approach to interacting electronic systems and discuss its numerical implementation.
This method is designed for a self-consistent description of multi-orbital systems that can also have several atoms in the unit cell.
The current implementation of the D-TRILEX approach is able to account for the frequency- and channel-dependent long-ranged electronic interactions.
We show that our method is accurate when applied to small multi-band systems such as the Hubbard-Kanamori dimer.
Calculations for the extended Hubbard, the two-orbital Hubbard-Kanamori, and the bilayer Hubbard models are also discussed.

Published: August 2022

Aims:

The present paper focused on compare the PID-5 mean score levels across two matched community and clinical samples of Portugal and the UAE.

Background:

The generalizability and universality of the Alternative Model of Personality Disorders has been thoroughly studied through the Personality Inventory for DSM-5 (PID-5) across countries and languages. However, studies comparing Western and Middle Eastern countries are still limited, in particular those who assess the PID-5 measurement invariance.

Objectives:

We examined measurement invariance of the PID-5 scales across matched Emirati and Portuguese clinical and nonclinical groups, as well as compare and contrast the PID-5 mean score levels across both countries and samples.

Methods:

The Arabic and the Portuguese versions of the PID-5 was administered to Emirati community participants (N = 300, 80% women and 20% men, Mage = 27.95) which were matched with Portuguese community participants (N = 300, 80.3% women and 19.7% men, Mage = 28.96), as well as clinical participants of the UAE (N = 150, 61.3% women and 38.7% men, Mage = 31.29) and Portugal (N = 150, 52% men and 48% women, Mage = 44.97). We examined measurement invariance through an unrestricted Factor Analysis based program, and mean scores levels were compared and analyzed.

Results:

Our findings supported the PID-5 measurement invariance across the Emirati and Portuguese clinical samples pointing to the universality and generalizability of the Alternative Model of Personality Disorders. The Emirati psychiatric sample exhibited somehow higher results than the Portuguese psychiatric participants, albeit the small effect size for most of the PID-5 scales.

Conclusion:

Further research is needed to examine the applicability of the PID-5 across non-clinical representative samples of Portugal and the UAE, and other Middle Eastern countries.

Published: August 2022

Background:

Most commonly reported clinical manifestations are fever, fatigue and dry cough.
Interestingly, a small percentage of patients experience GI symptoms, with the most common being anorexia,
diarrhea, nausea and vomiting. We aimed to conduct a comparative study on COVID-19 patients
with or without gastrointestinal patients (GI).

Aims:

The pandemic of coronavirus disease 2019 (COVID-19) has emerged as a dire health problem,
causing a massive crisis for global health.

Methods:

Collective data of clinical manifestations and laboratory reports of patients admitted to Razi
Hospital, Ahvaz, Khuzestan, Iran, for two weeks were analyzed.

Results:

Our results showed that GI symptoms are not statistically significant criteria to be predictive or
prognostic factors in COVID-19 patients, although they are probably related to the acute or non-acute
phase of the disease. Moreover, non-specific GI symptoms seem to result from cytokine storm that occurred
during the disease.

Conclusion:

Therefore, our results did not support GI tract involvement as a common route of COVID-
19 infection. Maybe future research will shed light on why and how the gastrointestinal system becomes
infected by COVID-19.
Clay-derived Synthesis of Supported α-Fe2O3 Nanoparticles: Shape,
Adsorption, and Photo-catalysis
Authors: Su Xintai , Li Xue , Meng Linrong , Hao Tao , Wang Guofeng
Published: August 2022

Background:

This paper reports a versatile bentonite clay-mediated growth method for
selectively synthesizing zero-dimensional α-Fe2O3 nanoparticles and one-dimensional α-Fe2O3 nanorods.

Method:

In such a growth process without any other surfactant or additive, the bentonite clay is not
only used as the supporter, but also as a shape mediator for α-Fe2O3 nanocrystals. The products
were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM).

Results:

The as-prepared products were used to investigate their promising adsorptive and photocatalytic
applications in water treatment. According to the Langmuir equation, the maximum adsorption
capacity of the α-Fe2O3/bentonite composite for Congo red (CR) is calculated to be 96.9
mg·g-1. Furthermore, the α-Fe2O3/bentonite nanocomposites also show an excellent photocatalytic
property in the degradation of methyl orange (MO).

Conclusion:

This facile and novel synthesis method has the potential to be applied to prepare the
low-cost α-Fe2O3/bentonite nanocomposite for the removal of CR and MO.
Development of Copper Nanoparticle Conjugated Chitosan Microparticle
as a Stable Source of 2nm Copper Nanoparticle Effective against Methicillin-
resistant Staphylococcus aureus
Authors: Dastidar Debabrata Ghosh , Singh Prabhakar , Bhattacharjee Romit , Ghosh Dipanjan , Banerjee Malabika , Biswas Samik , Mukherjee Samir Kumar , Mandal Supratim
Published: August 2022

Background:

Copper nanoparticle (CuNP) has well-established antimicrobial activity. Instability
in an aqueous medium due to aggregation into larger particles, conversion into metal ions,
and oxidation into metal oxides are the major limitations of its practical use against bacterial infections.

Objective:

Development of CuNP Conjugated Chitosan Microparticles as a reservoir that will release
CuNP effective against notorious bacteria like Methicillin-resistant Staphylococcus aureus.

Methods:

CuNP conjugated chitosan microparticles (CNCCM) were synthesized using a simple twostep
process. In the first step, a solution of chitosan in 2% (w/v) ascorbic acid was added dropwise in
copper sulphate solution to prepare Cu ion conjugated chitosan beads. In the second step, these beads
were soaked in sodium hydroxide solution to get the CNCCM. The dried CNCCM were characterized
thoroughly for surface conjugation of CuNP, and the release of CuNP in a suitable medium. The physicochemical
properties of release CuNP were further verified with the in silico modelled CuNP. The
Antimicrobial and antibiofilm activities of released CuNp were evaluated against methicillin-resistant
Staphylococcus aureus (MRSA).

Result:

2% (w/v) ascorbic acid solution (pH 3.5) was the optimum medium for the release of ~2 nm
CuNP from CNCCM. The CuNP had an optical band gap of ~ 2 eV. It inhibited the cell wall synthesis
of MRSA. The minimum inhibitory concentration was 200 nM. At 100 nM dose, the CuNP caused
∼73% reduction in biofilm development after 24 h of growth. The cytotoxic effect of CuNP on the
human cell line (HEK 293) was significantly less than that on MRSA. The 48 h IC50 value against
HEK 293 was 3.45-fold higher than the MIC value against MRSA after 24 h treatment.

Conclusion:

CuNP Conjugated Chitosan Microparticle has been developed. It works as a stable reservoir
of ~2 nm CuNP. The CuNP is released in an aqueous medium containing 2% (w/v) ascorbic acid
(pH 3.5). The released CuNP has a bacteriostatic effect against MRSA at a concentration safe for human
cells.

increasingly explored in nanotechnology owing to their chemophysical properties, self-assembly,
and low toxicity.

Introduction:

CNCs can be isolated from various cellulosic biomass sources. Textiles which are
mostly made of cotton, are under-utilized biomass that after their lifetime is either burned or
dumped into landfills.

Method:

In this study, cotton-based textiles are studied as a source of CNCs. CNCs were extracted
from textiles with and without bleaching before the acid hydrolysis step, and further comparing
them with the properties of industrial microcrystalline cellulose-derived CNCs. Nanocrystals were
synthesized from the three different sources and their morphology, thermal properties, and colloidal
stability were compared.

Results:

The result show similar thermal properties and morphological characteristics for the three
synthesized CNCs, and similar colloidal stability between the two textile-based CNC dispersions,
suggesting that the dyes on CNCs do not impact the quality of the product. Removing the bleaching
pre-treatment -a water-demanding and toxically harmful step- before CNC extraction provides cost
and environmental benefits without compromising on the CNC quality.

Conclusion:

This project seeks to streamline the CNC synthesis process with the long-term goal of
eventually facilitating the textile recycling industry.

Published: August 2022

Leaf blight Phytophthora colocasiae is one of the main diseases in taro plants which can reduce production yield significantly. Weather is one of the main factors supporting the epidemic of leaf blight. Weather changes will affect the development of pathogens and affect the development of disease in the field. This research aimed to find out the effect of weather elements (air temperature, humidity, sunlight intensity, rainfall, number of rainy days) on the intensity of the taro leaf blight attack. The results showed that weather elements had a significant correlation with the intensity of taro leaf blight disease. Air temperature and sunlight intensity showed negative correlations while air humidity, rainfall and the number of rainy days were positively correlated with the disease intensity. The results of this path analysis showed that air humidity had the most significant effect of the weather elements on the intensity of taro leaf blight both directly and indirectly.

Published: August 2022

Background

Health care utilization after coronary artery bypass graft (CABG) surgery is high and is partly of an unplanned nature. eHealth applications have been proposed to reduce care consumption, which involve and assist patients in their recovery. In this way, health care expenses could be reduced and quality of care could be improved.

Objective

The aim of this study was to evaluate if an eHealth program can reduce unplanned health care utilization and improve mental and physical health in the first 6 weeks after CABG surgery.

Methods

A single-blind randomized controlled trial was performed, in which patients scheduled for nonacute CABG surgery were included from a single center in the Netherlands between February 2020 and October 2021. Participants in the intervention group had, alongside standard care, access to an eHealth program consisting of online education videos and video consultations developed in conjunction with the Dutch Heart Foundation. The control group received standard care. The primary outcome was the volume and costs of a composite of unplanned health care utilization, including emergency department visits, outpatient clinic visits, rehospitalization, patient-initiated telephone consultations, and visits to a general practitioner, measured using the Medical Technology Assessment Medical Consumption Questionnaire. Patient-reported anxiety and recovery were also assessed. Intention-to-treat and “users-only” analyses were used.

Results

During the study period, 280 patients were enrolled and randomly allocated at a 1:1 ratio to the intervention or control group. The intention-to-treat analysis consisted of 136 and 135 patients in the intervention and control group, respectively. At 6 weeks, the primary endpoint had occurred in 43 of 136 (31.6%) patients in the intervention group and in 61 of 135 (45.2%) patients in the control group (hazard ratio 0.56, 95% CI 0.34-0.92). Recovery was faster in the intervention group, whereas anxiety was similar between study groups. “Users-only” analysis yielded similar results.

Conclusions

An eHealth strategy comprising educational videos and video consultations can reduce unplanned health care utilization and can aid in faster patient-reported recovery in patients following CABG surgery.

Authors: Yabumoto Megan , Miller Emily G , Rao Anoushka , Tabor Holly , Ormond Kelly , Halley Meghan
Published: August 2022

BACKGROUND

Social media provides a potential avenue for genetic counselors (GCs) to address gaps in access to reliable genetics information for rare disease communities, but little research has examined patient and family attitudes toward online engagement. Our study assessed the attitudes of members of rare disease social media groups regarding such engagement, characteristics associated with greater interest in engagement, and the benefits and potential pitfalls of various approaches to engaging with GCs through social media.

OBJECTIVE

This study used an innovative sampling methodology to obtain a diverse, systematic sample of rare disease social media support groups. We aimed to use this large sample to elicit group members' perspectives on the type of support services that genomics professionals may uniquely be able to provide in an online setting.

METHODS

We conducted a mixed-methods survey of patients and family members recruited from a systematic sample of rare disease Facebook groups. Patient characteristics and their association with interest in engagement with GCs were evaluated using univariate and bivariate statistics. Open-ended responses were analyzed using thematic content analysis.

RESULTS

One-thousand and fifty-three individuals from 103 rare disease groups participated. Median overall interest in engaging with GCs on social media was moderately high at 7.0 (IQR=4.0-9.0, range 0-10). No past experience with a GC was associated with greater interest in engaging online (µ=6.5 vs. 6.0, P=0.04). Participants expressed greatest interest (median=9.0, IQR=5.0-10.0) in engagement models allowing direct communication with GCs, including individualized support, but also expressed concerns regarding privacy.

CONCLUSIONS

Patients and family members in rare disease social media groups appear interested in engaging with GCs online, particularly for individualized support. While encouraging, concerns regarding privacy and feasibility require further consideration, pointing to the need for professional guidelines in this area.

Authors: Mittmann Gloria , Zehetner Vanessa , Hoehl Stefanie , Schrank Beate , Barnard Adam , Woodcock Kate
Published: August 2022

BACKGROUND

Augmented reality (AR) has emerged as a promising technology in educational settings owing to its engaging nature. However, apart from applications aimed at the autism spectrum disorder population, the potential of AR in social-emotional learning has received less attention.

OBJECTIVE

This scoping review aims to map the range of AR applications that improve social skills and map the characteristics of such applications.

METHODS

In total, 2 independent researchers screened 2748 records derived from 3 databases in December 2021—PubMed, IEEE Xplore, and ACM Guide to Computing Literature. In addition, the reference lists of all the included records and existing reviews were screened. Records that had developed a prototype with the main outcome of improving social skills were included in the scoping review. Included records were narratively described for their content regarding AR and social skills, their target populations, and their outcomes. Evaluation studies were assessed for methodological quality.

RESULTS

A total of 17 records met the inclusion criteria for this study. Overall, 10 records describe applications for children with autism, primarily teaching about reading emotions in facial expressions; 7 records describe applications for a general population, targeting both children and adults, with a diverse range of outcome goals. The methodological quality of evaluation studies was found to be weak.

CONCLUSIONS

Most applications are designed to be used alone, although AR is well suited to facilitating real-world interactions during a digital experience, including interactions with other people. Therefore, future AR applications could endorse social skills in a general population in more complex group settings.

Published: August 2022

In a close future, in which cultural heritage will represent a path with historical value and will be studied by the aesthetic, ethnological or anthropological point of view, the urban rehabilitation will appear as a commitment between the past and the present (future) and the sustainable, inclusive and intelligent development. Linking all these elements with all of different characteristics, from an objective point of view, the investigation will not seek miraculous solutions to old difficulties of spatial planning or rapid resolution of emerging problems, because more than expanding the generalist field of knowledge or giving a new academic precision to an empirical approach, the research aims to deepen scientific knowledge about the fishing settlements located on the border line provided by the sea line, and about the rural settlements delimited by the plow wake that once furrowed the land, with resilient particularities achieved in an unique and shared ambience because we will support the investigation in this “living-lab” and reply this research as a model on similar large-scale environments on Earth.
El Señor de los Rayos. Nuevas formas para una antigua iconología
Authors: López García Jesús
Published: August 2022

En la década de los cincuenta del siglo XX, años antes del Concilio Vaticano II, comenzó en Aguascalientes, México, una nueva era de edificación religiosa, en la que se emplearon medios constructivos actuales y mecanismos de significación plástica modernos; con ello, en materia arquitectónica, en la diócesis se estableció un nuevo paradigma: geometrías y configuraciones novedosas. Dentro del acervo resultante, el templo del Señor de los Rayos tiene una connotación especial por desapegarse de la tendencia sin ornamentos iconográficos; por el contrario, apeló a la iconología a través de una portada que, aún apartada de la composición tradicional de cuerpos y calles, remite directamente a imágenes ancestrales del repertorio cristiano en una composición escultórica sobrepuesta, resultando en un edificio desconcertante y único en Aguascalientes, rupturista y paradójicamente tradicional también.

An Experimental Investigation on Banana Fibre Concrete with Nano Silica
Authors: Chandramouli Dr. K. , Chaitanya J. Sree Naga , Abdullah Mohammad
Published: August 2022

Abstract: The combined impact of using banana fibres (BF) and nano-silica (NS) on the mechanical properties of hardened concrete is examined in this study. In order to partially replace cement, NS has been used in amounts of 0, 2, 2.5, 3, 3.5, 4, and 4.5% by weight, and BF has been used in amounts of 1, 2, 3, 4, and 6% by volume. Banana fibres measuring 40 mm in length were used in the current experiment. A variety of NS and BF combinations are used to calculate the test values for compression strength, split tensile strength, and pulse velocity. Due to its tiny particle size, nano-silica can change the properties of concrete by changing its microstructure. Because of NS's high pozzolanic activity, which supports the generation of more C-S-H gel in the presence of nanoparticles, a noticeable improvement in the strength qualities of concrete is shown when NS is utilised. The strength and longevity of the concrete will be greatly enhanced by the use of NS. On the other hand, the inclusion of banana fibres to the concrete gradually reduces permeability and improves crack resistance.

Published: August 2022

Abstract: In this study, silica fume, which is finer than cement and used to substitute cement, gave concrete structures more strength and longevity. Steel fibres are utilised to improve the ductility and strength of concrete. 50% of the coarse aggregate was replaced with the 50% demolition waste aggregate. Cement with varying amounts of silica fume added (5, 10, 15, and 20%). For hardened concrete, strength tests are carried out at 7 and 28 days to assess the strength, such as compressive and split tensile. Increasing the strength parameters was made possible by the partial replacements of 10-15% of the combined use of silica fume and fly ash.
