Data Genocide: Are Minority Opinions Being Murdered Online?
Authors: Davis Rose
Published: May 2021

With the advent of the internet in 1983, many people believed it offered the chance for humanity to evolve as a civilization, no longer needing to resort to war, genocide, and violence as a way for power and control. The internet brought freedom, a new way of communication, sharing information, connecting people globally, and moving data. Few at the time likely anticipated that it would quickly become a digital wild west where laws were scarce and the ability to manipulate, influence, control, and ultimately dominate would become powerful forces of change impacting society well beyond the digital realm. From its early days to today an unimaginable amount of data and information has been created containing secrets and indications of every participant in this arena. The rights of the individual to own their data were seemingly lost to the legal constructs of internet companies through crafty terms of service, license agreements, and sophisticated collection mechanisms. Tech giants like Facebook, Amazon, Alphabet, Netflix, and Google, known as the FAANG’s, are examples of those that collect untold amounts of information on every user of their services. While they are not alone in their pursuit of data, they are clear examples of successful companies who recognized this unclaimed territory and quickly took advantage to create their own empires. Today, they have built something that we could have never imagined existing back in 1983—a digital empire where we can instantly connect with each other across the globe, quickly access extraordinary amounts of information, and conveniently complete many tasks for ourselves. While this all seems like pleasantries, what lies underneath is a group of Big Tech companies clawing their way to the top and destroying new competitors in their path for means of power and control. The benefits we “receive” are a facade for their true motivation of gaining total power and control of many forms of information. Voices have been silenced for expressing their beliefs, for sharing opposing opinions to the common narrative, and becoming competitive threats. Meanwhile, we continue to scroll, click, upload, and share our lives and information again and again. What is worse, is how easy it is for them to do it in the absence of strong oversite and accountability. Rather, society at large has let them self-govern and freely push forward their own agendas. These tech giants are now making up the rules as they go, while we, as a world, have ignored the signs and warnings from countless scholars on the dangers of self-regulation and feigned moral authority. What we are experiencing now is a threat to everyone’s free speech, individual rights over their data, online identity, and as this paper will set forth, perhaps even our digital lives if not, in certain circumstances, our physical lives as well; something everybody should be worried about.

Objective: To evaluate the impact of surgical experience on the outcomes of retrograde intrarenal surgery (RIRS) to treat kidney stones.

Material and Method: Retrospective chart review of patients who underwent RIRS between November 1st, 2014 and January 11th, 2017; the outcomes were divided into 2 groups. Group 1 was the less experienced surgeons (fewer than 30 cases for each surgeon) whereas group 2 was the highly experienced surgeon (more than 300 cases). The surgical outcomes, including operative time, stone-free rates, complications and scope damage, were compared between the 2 groups.

Results: There were 6 surgeons in group 1 and a single surgeon in group 2. Seventy-four procedures were performed by group 1. Group 2 included the first 30 procedures after the surgeon had passed the learning curve. Patient demographic data, including age, sex and location of the stone, were not different between group 1 and group 2. Group 1 had a smaller stone size than group 2 (1.59 cm vs. 2.34 cm; p=0.006). The outcomes of group 2 were better than group 1, including operative time (80.48 minutes vs. 43.50 minutes; p<0.001) and stone-free rates (52.05% vs. 90%; p<0.001). Serious complications were determined to be sepsis or a high degree of ureter injury that required surgical correction. Sepsis occurred in 6 patients in group 1 (8.10%), whereas no sepsis was found in group 2 (p=0.013). There was no high degree of ureteric injury in either group. Three scopes were damaged in group 1 whereas no scope damage occurred in group 2 (p=0.045).

Conclusion: RIRS is a popular procedure for the treatment of kidney stones. Surgical experience is mandatory to achieve excellent outcomes.Keywords: retrograde intrarenalsurgery, kidney stone, surgical experience
The Recovery of Traditional Cultural Values in Rural Area in North Vietnam in the Doi Moi Period
Authors: Huan Do Danh
Published: May 2021

Due to the lingering impacts of the Vietnam war and the difficulties that Vietnam has been confronting in the post-war period, traditional cultural values in rural areas in North Vietnam were neglected. Since Đổi mới (in 1986), the Communist Party of Vietnam and the Vietnamese government have drawn more concern and been thoroughly aware of the role of culture on Vietnam’s developing path of the country. In addition, the remarkable growth of Vietnam’s economy recently paves the way for Vietnamese residents to rebuild and renew their spiritual lifeas well as enjoy benefits created based on traditional cultural values. This research elucidates the resilience of conventional cultural values in rural areas in North Vietnam in the Đổi mới period, particularly emphasizing the following aspects: Inhabitants’ contributions to build and rebuild temples and pagodas; reinstating conventional rituals and festivals; restoring family customs, and compiling village convention.

Published: May 2021

A partir de 2013, os Hospitais Universitários federais foram incentivados a aderir à Empresa Brasileira de Serviços Hospitalares (EBSERH). Ao final de 2017 apenas quatro Instituições Federais de Ensino Superior não aderiram a essa empresa. O artigo propõe identificar e discutir mudanças dos HUs, sejam eles contratualizados ou não com a EBSERH, com a finalidade de compreender e discutir o papel dos modelos de gestão sobre recursos físicos, humanos, produção e ocupação hospitalar no período entre 2012 e 2017, em que a maioria dos contratos foram estabelecidos. Trata-se de um estudo ecológico exploratório descritivo, analítico e retrospectivo, utilizando dados secundários de bancos oficiais públicos do Sistema Único de Saúde (SUS). Em ambos os modelos, verificou-se que houve um crescimento dos leitos complementares e número de trabalhadores e residentes junto a redução dos leitos hospitalares.  Foi destacável o crescimento das internações e da taxa de ocupação em ambos os modelos de gestão. Não houve significância estatística nas médias de variação de todas as variáveis estudadas em ambos os modelos. Apenas foi verificada uma correlação negativa e significativa entre a variação da taxa de ocupação e os leitos hospitalares no conjunto dos hospitais contratualizados com a EBSERH, evidenciando que o crescimento das internações desses hospitais pode ser explicado por uma maior utilização de um menor número de leitos.
Impact of surgery in otosclerosis on the non-operated ear
Authors: Wiatr Agnieszka , Job Katarzyna , Składzień Jacek , Wiatr Maciej
Published: May 2021

Backgrounds
Otosclerosis is an underlying disease of the bony labyrinth. The hearing loss is most often of conductive nature, in some cases the involvement of the bony part of the cochlea results in mixed hearing loss.
Aims:
The aim of the analysis was to answer the question whether a surgery on one of the ears affects the state of the other ear in the course of otosclerosis.
Methods
The analysis included 140 patients hospitalized and operated on between 2010 - 2016.
Only patients who had not had a surgical operation within the middle ear due to otosclerosis prior to the study were included in it.
An audiological assessment was performed with the use of pure tone threshold audiometry taking into account.
Results
In the group of patients with no Carhart's notch, the mean threshold of bone conduction was statistically lower than before the procedure for the frequencies of 500, 1000 Hz and statistically equal for the frequency of 2000 Hz. The same analysis in the group of patients with Carhart's notch present in the pre-surgical tonal audiogram of the non-operated ear showed a statistically significant lower value of the post-surgical threshold bone conduction value.
Conclusion
It was confirmed the possibility of improving the hearing of the non-operated ear after the stapedotomy of the opposite ear, in the author's own studies by an average of 5 dB in the low-frequency range.
Breast fibroadenomas: a review in the light of current
literature
Authors: Salati Sajad Ahmad
Published: May 2021

Introduction: Fibroadenomas are one of the most common benign tumors of the breast in the adolescent females accounting for about 2/3rd of all the breast lumps and more than half of all the biopsied breast lesions. They come into being due to overgrowth of glandular tissue under the influence of hormonal changes that the girls undergo at the time of puberty. Due to the wide prevalence of fibroadenomas and the psychosocial morbidity associated with the finding of a breast mass, it is imperative for physicians treating adolescent patients to be thoroughly familiar and updated with this disease.
Aim: The article aims at providing a brief review of the classification, presentation, diagnosis, and update on the management of breast fibroadenomas on the basis of recent literature.
Outcomes of Endoscopic Totally Extraperitoneal (TEP) Hernia Repair for Clinically Occult Inguinal Hernia Diagnosed With Ultrasonography
Authors: kebabci eyup , Ozturk Safak , Unver Mutlu
Published: May 2021

Background: Inguinal hernias are generally presented by groin mass and pain. An inguinal hernia can be diagnosed clinically in most cases but patients without a groin lump constitutes a diagnostic challenge. The firstline diagnostic imaging tool for these patients is ultrasound (US) and the recommended surgical procedure is laparoscopic-endoscopic repair. The aim of this retrospective study is to evaluate the postoperative results and complication rates of TEP technique in patients with contralateral occult hernias diagnosed with US and clinically diagnosed hernias.
Methods: A retrospective study was conducted to evaluate the outcomes of TEP procedure in patients with radiologically diagnosed contralateral occult hernias and clinically diagnosed patients. All the defects were repaired by TEP technique and covered with a mesh that was placed extraperitoneally.Demographics, patient characteristics and perioperative data were obtained by reviewing the records.
Results: A total of 109 patients were enrolled in the study. Most of patients were male and the mean age was 48.9 ± 14.6. The hernias of 56 patients were repaired unilaterally and the rest bilaterally. Right-sided hernias were more common than left-sided hernias. The morbidity rate was 7.1% in unilateral repair and 3.8% in bilateral repair. The recurrence rate was 3.6% in unilateral repair and 5.7% in bilateral repair.
Conclusion: The reported incidence of clinical contralateral groin hernia after primary unilateral surgery is approximately 10% in some studies. If the contralateral side could be diagnosed before primary surgery, the risk of a second operation could be avoided. Laparoscopic surgery enables bilateral hernia repair without any additional incision with similar morbidity rates. There was no significant difference between unilateral and bilateral TEP repair for intraoperative and postoperative surgical complications. These results suggest that laparoscopic inguinal hernia repair is safe and effective surgical technique for both unilaterally and bilaterally. To prevent a second operation, all patients with suspected inguinal hernia should have an ultrasound before surgery.

Background: Acne vulgaris occurs most often in young people and can significantly decrease the quality of life. Properly selected dermatological therapy and cosmetic procedures can effectively improve the skin condition of acne patients.
Aim of the study: The aim of this study was to examine how various cosmetics treatments affect facial sebum levels, skin hydration, and desquamation in young women with acne vulgaris.

Material and Methods: 101 women with acne aged 19–29 (M = 22.5 years, SD = 2.3 years) were included in the study. The following cosmetic treatments were used over a 12-week period: intensive pulsing light, alpha-hydroxy acids, cavitation peeling, non-needle mesotherapy, diamond microdermabrasion, and sonophoresis. Skin parameters, including oily skin level, desquamation level, and moisture level were analyzed twice (at baseline and after 12 weeks) using a Nati skin analyzer.
Results: The series of cosmetic procedures significantly improved skin lubrication (p<0.0001), hydration in the T zone (p<0.0001), and desquamation (p< 0.0001).
Conclusions: The use of modern cosmetic devices in the beauty studio can be very effective for the treatment of acne lesions.
Poznavanje izabranih radnih prava među maturantima srednjih strukovnih škola u Hrvatskoj
Authors: Jeknić Ranka , Čop Branka
Published: May 2021

U radu se analiziraju rezultati anketnog istraživanja o poznavanju izabranih radnih prava među maturantima srednjih strukovnih škola u Hrvatskoj. Istraživanje je provedeno tijekom 2019. u okviru EU projekta Znanjem do prava na uzorku od 1 102 maturanta iz 54 srednje strukovne škole različitih trogodišnjih, četverogodišnjih i petogodišnjih programa. Primjenom deskriptivne statistike i regresijske analize, u radu se nastoji ustanoviti postoje li razlike u pokazanom znanju o radnim pravima i povezanost sociodemografskih i obrazovanih karakteristika ispitanika s razinom pravne pismenosti. Rezultati upućuju na njihovo relativno slabo poznavanje i nisku razinu pravne pismenosti iz područja izabranih radnih prava te povezanost sociodemografskih i obrazovnih obilježja ispitanika s indeksom ukupnog znanja o izabranim radnim pravima. Regresijska analiza pokazuje kako varijabla spola ima najveći utjecaj na razinu pravne pismenosti među ispitanim maturantima srednjih strukovnih škola. Osim u sagledavanju aktualnog stanja u pogledu znanja ispitanih maturanata srednjih strukovnih škola o izabranim radnim pravima, te poticanju akademskih i javnih rasprava, nalazi ovog istraživanja mogu imati aplikativnu vrijednost pri izradama plana i programa građanskog odgoja i obrazovanja na različitim obrazovnim razinama, kao i za razvoj i planiranje sindikalnog djelovanja u Hrvatskoj u pogledu regrutacije novog članstva. Istraživački nalazi potencijalno pridonose i kod nas nedovoljno istraženim temama pravnog znanja, pravne pismenosti, pravne kulture i pravne socijalizacije putem koje se ta znanja usvajaju.
"Ženski sport nije pravi sport": negativni stereotipi prema sportašicama i doživljaj rodne neravnopravnosti u rukometu u Hrvatskoj
Authors: Greblo Jurakić Zrinka , Ljubičić Višnja , Bojić-Ćaćić Lidija
Published: May 2021

Osnovni cilj istraživanja bio je utvrditi koliko se često mladi rukometaši i rukometašice susreću s negativnim stereotipima prema sportašicama. Osim spomenutoga, ispitali smo razlikuju li se sportašice koje su u različitom stupnju izložene negativnim stereotipima u doživljaju rodne neravnopravnosti koja se očituje u nejednakim uvjetima treniranja i nejednakom načinu vrednovanja sportskih postignuća mladića i djevojaka koji treniraju u njihovom sportskom klubu. U istraživanju je sudjelovalo 522 rukometaša/ica (289 mladića i 233 djevojaka) čiji se raspon dobi kretao od 14 do 17 godina (M=14,75; SD=0,96). Prema dobivenim rezultatima, s negativnim se stereotipima prema sportašicama i/ili sportu u kojem sudjeluju djevojke susrelo 94,5% mladića i 95,6% djevojaka. Mlade su sportašice češće izložene stavu prema kojem sport nije aktivnost namijenjena djevojkama (U=28188,00, p<0,05), odnosno stavu koji podrazumijeva da sport u kojem sudjeluju žene nije atraktivan (U=28111,00, p<0,05). Djevojke koje se češće susreću s negativnim stereotipima prema sportašicama statistički značajno češće navode da sportaši i sportašice u njihovom klubu ne treniraju u jednakim uvjetima (U=3551,000, p<0,001) te da se njihovi sportski uspjesi ne vrednuju na isti način (U=3353,500, p<0,001). Dobiveni rezultati upućuju na potrebu za poduzimanjem mjera s ciljem suzbijanja negativnih stereotipa prema sportašicama te omogućavanja jednakih uvjeta treniranja i vrednovanja sportskih rezultata sportaša i sportašica.

In Istoria cunoasterii lor, hormonii au trecut de la statutul de ingeri si demoni misteriosi ai organismului nostru, la una dintre cele mai dezbatute si explorate specialitati medicale. Este dovedit faptul ca hormonii controleaza (aproape) totul: cresterea, metabolismul, comportamentul, sexul si reproducerea, lactatia, ciclurile somn-veghe, schimbarile de dispozitie, stresul, durerea, sistemul imunitar, lupta si abandonul... Ceea ce ii face sa fie atat de remarcabili – in comparatie cu toate celelalte biomolecule – este modul aparent magic in care ei functioneaza: ei „excita” receptorii unor celule-tinta, apasand pe „intrerupatoare” ce declanseaza sau stopeaza procesele biochimice. Studiul hormonilor este fascinant deoarece el integreaza biochimia, anatomia, fiziologia si patologia...Cele mai noi descoperiri in biologia celulara si moleculara, in imunologie si genetica, explica in prezent mecanismele secretiei si actiunii hormonilor, si mecanismele bolilor endocrine, deci au o aplicabilitate si un impact major in elaborarea unor tratamente vitale.

Objectives: The present study aimed at evaluating the prevalence of posttraumatic stress disorder (PTSD) following childbirth and its sociodemographic and obstetrics predictors. Methods: The current cross sectional study was conducted from April to November 2017 by the random sampling method on 365 women aged 18 - 35 years whose last childbirth occurred within 38 - 42 weeks of gestation and gave birth 10 - 16 weeks before the initiation of the study, in Baneh City, Kurdistan Province, Iran. The research tools included a sociodemographic and obstetrics characteristics questionnaire and a checklist of PTSD for DSM-IV. For data analysis, independent t-test, one-way ANOVA, and multiple linear regression with backward stepwise selection were employed. Results: The prevalence of PTSD following childbirth was 47.7%. The mean ± standard deviation of PTSD following childbirth was 13.6 ± 10.9, out of the attainable score of 0 - 51. The variables, including income status, number of children, desired route of delivery, and the type of recent delivery, were identified as predictors and accounted for 34% of the variance of PTSD adjusted for other variables. Conclusions: Considering the high prevalence of PTSD following childbirth, to improve the childbirth experience, well-adjusted interventions should be planned to prevent PTSD after delivery.
On ant-like Synemosyna Hentz, 1846 spiders from Bolivia, with indirect evidence for polymorphic mimicry complexes (Araneae: Salticidae: Simonellini)

Three species of Synemosyna Hentz, 1846 were recorded during a survey in five Bolivian forest ecoregions: S. aurantiaca (Mello-Leitão, 1917), S. myrmeciaeformis (Taczanowski, 1871) and S. nicaraguaensis Cutler, 1993. Synemosyna aurantiaca and S. nicaraguaensis are recorded for Bolivia for the first time and the previously unknown male of S. nicaraguaensis is described and illustrated. The habitus and the genitalia of the female of S. myrmeciaeformis are illustrated for the first time. Synemosyna aurantiaca occurs in semi-deciduous forests south of 18° S and S. myrmeciaeformis in the Bolivian Yungas forest and ecoregions of the Amazon biome north of 16° S. Synemosyna nicaraguaensis is possibly an Andean species that enters into the moist Isthmian forests of Central America. Several potential mimicry complexes with two broad patterns were observed: sex-specific polychromatic mimicry (S. nicaraguaensis), and transformational mimicry involving smaller orange and larger brown to dark-brown forms (S. aurantiaca and S. myrmeciaeformis).

The use of composite materials is increasingly present not only in several industrial areas but also in daily life. With the escalating environmental concern, it is necessary the search for materials that prove to be ecologically sustainable and economically viable. Vegetable fibers have been presenting themselves as an excellent alternative, however, because their disadvantage of having a high moisture absorption capacity, the introduction of synthetic fibers, forming hybrid composites, is a good solution since it combines the characteristics of both types of reinforcements. The present research aims to carry out a comparative study between two types of laminated polymer composites, one reinforced with Jute fibers and the other hybrid, composed of Jute and E-glass fibers. The mechanical performances of the composites submitted to the Uniaxial Tensile, Three-point Flexural and Shear tests were evaluated, as well as fracture analyzes. A comparative study to analyze the influence of hybridization on moisture absorption was carried out. The results showed that the hybridized composite showed an increase in the elastic modulus, as well as in its resistance to flexion and shear, which shows the formation of a more rigid material. Hybridization also changed the moisture content of the composite.

Bio-filler from eggshells as reinforcement of bio-based polymers are based on their benefits as adequate strength and stiffness, besides friendly, degradable and renewable environment. Eggshell is an agricultural waste considered as garbage, contributing to pollution; nevertheless, it can be transformed into bio-calcium carbonate, acquiring new values. As biodegradable polymers, there were chosen PLA (poly-lactic-acid) and PBAT (butylene adipate co-terephthalate), thermoplastics capable to be processed via conventional methods. PLA is a linear, aliphatic thermoplastic polyester, high in strength and modulus, but brittle. PBAT is a synthetic polymer, very flexible, based on fossil resources with high elongation at break, but low strength. It will be required the use of compatibilizers, for reducing interfacial tension exhibited by PLA/PBAT immiscible blend, considering their extreme glass transition temperatures: 62 o C for PLA and – 30 o C for PBAT. Herein it was used ionizing radiation for inducing compatibilization by free radicals, improving dispersion and adhesion of blend phases, without using chemical additives, at room temperature. PLA, acting as compatibilizer, was previously e-beam and gamma radiated, at 150 kGy. PBAT/PLA 50/50 blend with 15 phr of bio-filler from avian eggs 125 µm particle size and both compatibilizers were homogeneized in a co-rotating twin-screw extruder, within a temperature profile 120 to 145 o C, from hopper to die. Characterization involved: Differential Scanning Calorimeter, Thermogravimetric Analyses, Fourier Transform Infrared Spectroscopy, Wide Angle X-Ray Diffraction, Tensile Strength and Elongation at Break.

The presented work shows the synthesis and characterization of Zn/Ti layered double hydroxide (LDH) intercalated with carbonate and dodecyl sulfate ions following its application as a functional filler in LDPE in order to improve the thermal properties and resistance degradation in UV-Vis radiation. X-ray diffractogram patterns of Zn/Ti LDH-CO3 and Zn/Ti LDH-DDS present basal spacing value in the order of 6.81 Å and 38.09 Å, respectively, indicating success in layered compound synthesis. LDPE nanocomposite containing hydrophobic and hydrophilic LDH presented a very well dispersed nanocomposite, as demonstrated in XRD and DSC results. The addition of only 1 % of LDH as filler into LDPE causes an increase of 5.43 oC in the thermal property. Zn/Ti LDH-DDS absorbs more light compared to the Zn/Ti LDH-CO3 due to the enhanced interlayer distance in the presence of DDS in the basal space of LDH, which further the intercalation process of polymer chains within the interlayer regions of LDH.
Histoire des grèves d’élèves du secondaire au Québec : démocratie et conflictualité1
Authors: Dupuis-Déri Francis
Published: May 2021

Les élèves pratiquent la grève depuis plus d’un siècle, au Québec et ailleurs sur la planète. Une recherche dans les archives de la presse québécoise et 68 entretiens semi-dirigés ont permis de brosser un portrait − certes incomplet − des grèves d’élèves au Québec, d’en identifier les causes, les formes et surtout leur signification politique du point de vue des élèves. L’expérience de la grève leur permet d’évaluer l’intérêt politique des actions collectives autonomes et souvent de questionner le discours officiel qui réduit la « démocratie » aux élections et aux conseils d’élèves, comme le répètent en choeur le ministère de l’Éducation, l’Assemblée nationale, Élections Québec et plusieurs universitaires spécialistes de l’éducation à la citoyenneté.

The LRR-TM protein PAN-1 interacts with MYRF to promote its nuclear translocation in synaptic remodeling

Published: May 2021

Neural circuits develop through a plastic phase orchestrated by genetic programs and environmental signals. We have identified a leucine-rich-repeat domain transmembrane protein PAN-1 as a factor required for synaptic rewiring in C. elegans. PAN-1 localizes on cell membrane and binds with MYRF, a membrane-bound transcription factor indispensable for promoting synaptic rewiring. Full-length MYRF was known to undergo self-cleavage on ER membrane and release its transcriptional N-terminal fragment in cultured cells. We surprisingly find that MYRF trafficking to cell membrane before cleavage is pivotal for C. elegans development and the timing of N-MYRF release coincides with the onset of synaptic rewiring. On cell membrane PAN-1 and MYRF interact with each other via their extracellular regions. Loss of PAN-1 abolishes MYRF cell membrane localization, consequently blocking myrf-dependent neuronal rewiring process. Thus, through interactions with a cooperating factor on the cell membrane, MYRF may link cell surface activities to transcriptional cascades required for development.
Assessing anthropogenic heat flux of public cloud data centers: current and future trends
Authors: Baniata Hamza , Mahmood Sami , Kertesz Attila
Published: May 2021

Global average temperature had been significantly increasing during the past century, mainly due to the growing rates of greenhouse gas (GHG) emissions, leading to a global warming problem. Many research works indicated other causes of this problem, such as the anthropogenic heat flux (AHF). Cloud computing (CC) data centers (DCs), for example, perform massive computational tasks for end users, leading to emit huge amounts of waste heat towards the surrounding (local) atmosphere in the form of AHF. Out of the total power consumption of a public cloud DC, nearly 10% is wasted in the form of heat. In this paper, we quantitatively and qualitatively analyze the current state of AHF emissions of the top three cloud service providers (i.e., Google, Azure and Amazon) according to their average energy consumption and the global distribution of their DCs. In this study, we found that Microsoft Azure DCs emit the highest amounts of AHF, followed by Amazon and Google, respectively. We also found that Europe is the most negatively affected by AHF of public DCs, due to its small area relative to other continents and the large number of cloud DCs within. Accordingly, we present mean estimations of continental AHF density per square meter. Following our results, we found that the top three clouds (with waste heat at a rate of 1,720.512 MW) contribute an average of more than 2.8% out of averaged continental AHF emissions. Using this percentage, we provide future trends estimations of AHF densities in the period [2020–2100]. In one of the presented scenarios, our estimations predict that by 2100, AHF of public clouds DCs will reach 0.01 Wm−2.
Comparison of ultrafiltration and iron chloride flocculation in the preparation of aquatic viromes from contrasting sample types

Published: May 2021

Viral metagenomes (viromes) are a valuable untargeted tool for studying viral diversity and the central roles viruses play in host disease, ecology, and evolution. Establishing effective methods to concentrate and purify viral genomes prior to sequencing is essential for high quality viromes. Using virus spike-and-recovery experiments, we stepwise compared two common approaches for virus concentration, ultrafiltration and iron chloride flocculation, across diverse matrices: wastewater influent, wastewater secondary effluent, river water, and seawater. Viral DNA was purified by removing cellular DNA via chloroform cell lysis, filtration, and enzymatic degradation of extra-viral DNA. We found that viral genomes were concentrated 1-2 orders of magnitude more with ultrafiltration than iron chloride flocculation for all matrices and resulted in higher quality DNA suitable for amplification-free and long-read sequencing. Given its widespread use and utility as an inexpensive field method for virome sampling, we nonetheless sought to optimize iron flocculation. We found viruses were best concentrated in seawater with five-fold higher iron concentrations than the standard used, inhibition of DNase activity reduced purification effectiveness, and five-fold more iron was needed to flocculate viruses from freshwater than seawater—critical knowledge for those seeking to apply this broadly used method to freshwater virome samples. Overall, our results demonstrated that ultrafiltration and purification performed better than iron chloride flocculation and purification in the tested matrices. Given that the method performance depended on the solids content and salinity of the samples, we suggest spike-and-recovery experiments be applied when concentrating and purifying sample types that diverge from those tested here.
