Biocarbón de cascarilla de arroz como sustrato en el crecimiento de plántulas de pepino

El biocarbon es un material rico en carbono derivado de residuos vegetales y que se obtiene mediante tecnicas termoquimicas en un ambiente limitado de oxigeno o en ausencia de este. El objetivo fue evaluar las propiedades fisicas de mezclas de biocarbon de cascarilla de arroz como componente de sustrato y su efecto en el crecimiento de plantulas de pepino. Los tratamientos fueron: biocarbon de cascarilla de arroz (BC) y turba comercial (T; Sunshine mix 3), asi como mezclas de ambos en diferentes proporciones (20:80, 40:60, 60:40 y 80:20 %, respectivamente). Para la caracterizacion fisica se evaluo la granulometria, la densidad aparente, la porosidad total, la porosidad de aireacion y la porosidad de humedad. Adicionalmente, se determino la concentracion nutrimental. Para evaluar el efecto del biocarbon en el crecimiento de plantulas de pepino se considero la longitud de tallo, el peso fresco de biomasa aerea y de raiz, el area foliar, el peso seco de biomasa aerea y de raiz, y el contenido relativo de clorofila (lecturas SPAD). Se encontro que la adicion de hasta 40 % de BC al medio de crecimiento universal (turba) no altera las propiedades fisicas de porosidad total, porosidad de aireacion y porosidad de retencion de humedad; ademas, el crecimiento de plantulas de pepino en mezcla de BC al 20 % es similar en longitud de tallo, biomasa fresca, biomasa seca y area foliar a las plantulas cultivadas con 100 % de turba.

Local delivery of tetracycline group of drugs as adjuncts to mechanical debridement in peri-implantitis: a systematic review and meta-analysis

Peri-implantitis is associated with bone loss around a dental implant. Apart from mechanical factors, microbial etiology with gram-negative anaerobic infection is implied. The condition can have a favorable prognosis with timely control of infection, implant surface detoxification, and bone regeneration. Further, since it is site-specific, there is a potential for targeted form of antimicrobial therapy. Tetracycline has been the conventional choice for local delivery agents. The present review systematically assessed the randomized and controlled clinical trials, evaluating the efficacy of local delivery of the tetracycline group of drugs adjunctive to non-surgical peri-implant debridement in the management of mild to moderate cases of peri-implantitis. We explored databases of PubMed, Cochrane Library, and Scopus electronically to include research papers published in English till the end of May 2019. In the first stage of assortment, we screened titles and abstracts and in the second stage, the selected papers were evaluated independently by three reviewers. From the initial search, we included 810 related titles and abstracts. Around seven articles were selected for rigorous evaluation after screening. Finally, only three papers met the inclusion criteria and were selected for the final review and meta-analysis. Based on our analysis, we found scant evidence to support the tetracycline group of drugs in mild to moderate peri-implantitis. Research in this area is limited and warrants further investigation through longitudinal, randomized, and controlled clinical trials.
State of the Art and Latest Advances in Exploring Business Models for Nature-Based Solutions

Nature-based solutions (NBS) offer multiple solutions to urban challenges simultaneously, but realising funding for NBS remains a challenge. When the concept of NBS for societal challenges was first defined by the EC in 2017, financing was recognised as one of the major challenges to its mainstreaming. The complexity of NBS finance has its origin in the multiple benefits/stakeholders involved, which obscures the argument for both public and private sector investment. Since 2017, subsequent waves of EU research- and innovation-funded projects have substantially contributed to the knowledge base of funding and business models for NBS, particularly in the urban context. Collaborating and sharing knowledge through an EU Task Force, this first set of EU projects laid important knowledge foundations, reviewing existing literature, and compiling empirical evidence of different financing approaches and the business models that underpinned them. The second set of EU innovation actions advanced this knowledge base, developing and testing new implementation models, business model tools, and approaches. This paper presents the findings of these projects from a business model perspective to improve our understanding of the value propositions of NBS to support their mainstreaming.
"TRANSFORMATIONAL LEADERSHIP AND ITS IMPACT ON EMPLOYEE PERFORMANCE: FOCUS ON PUBLIC EMPLOYEES IN AFGHANISTAN"

"This study examines the relationship between transformational leadership and employee performance based on a survey conducted on 150 employees in low and middle level management positions in the Ministry of Public Works in Kabul, Afghanistan. The survey questionnaire consisted of questions about employee performance, transformational leadership (6 dimensions), pay satisfaction, job security, and demographic control variables. The result of OLS regression analysis concludes that two dimensions of transformational leadership – identifying and articulating a vision, and intellectual stimulation – are statistically significant and positively related to employee performance. In addition, job security is highly significant and related to employee performance. "
Knowledge, Attitude and Practices Regarding Nutrition among Adolescent Girls in Dhaka City: A Cross-sectional Study

Nutrition knowledge and positive attitude are known to influence dietary practices. Poor dietary practices are major contributors to the development of chronic non-communicable diseases. The aim of this study to explore the basic nutritional knowledge, attitude, and practices (KAP) among adolescent girls in Dhaka City. It was a cross-sectional study using a quantitative approach. A total of 500 adolescent girls (aged 10-19 yrs) from four schools and colleges were included in this study. The early adolescent and late adolescent girls’ age [yrs, (Mean ± SD)] was 12±1 and 17±1 respectively. About 31% of early adolescent girls were underweight according to different BMI categories (adapted from WHO guidelines-2004). The early adolescent girls’ 65% took breakfast before going to school but 43% skip to take lunch in school. And the late adolescent girl shows about 46% took breakfast before going to school but 30% skip to take lunch in school individually. The early adolescent girls’ nutritional knowledge score shows about 61.5% moderate, 86.5% remain positive attitude and 21.2% had good practices. Whereas late-adolescent girls’ nutritional knowledge score shows about 57.1% moderate, 90.1% remain positive attitude and 11.3% had good practices. Among the early adolescent girls shows the significant association of nutritional knowledge with attitude and practices (p=<0.001, p=0.005). Nevertheless, the late adolescent girls show only a significant association of nutritional knowledge with attitude (p=0.002). The results of the study revealed that adolescent girls having good knowledge, remain positive attitudes regarding nutrition, but practices were deficient in some aspects.
A prospective evaluation of retinopathy in diabetes patients with coexisting hypothyroidism

Background: Diabetes is the cause of 2.6% of global blindness which occur due to diabetic retinopathy caused by long term accumulated damage of small blood vessels in the retina. Hypothyroidism is common endocrine disorders that coexist with diabetes mellitus. Concurrent hypothyroidism, treated with thyroxin, appears to have a sparing effect on the risk of developing retinopathy among patients with type 2 diabetes.Material and method: This is a prospective observational study conducted in the department of ophthalmology. During our study period we have enrolled 240 patients with diabetes mellitus based on selection criteria and evaluated for diabetic retinopathy and hypothyroidism. A standard diagnostic criterion was followed for diagnosis of diabetes mellitus and all patients were assessed by two senior ophthalmologists for detection of retinopathy. Classification of diabetic retinopathy was based on the early treatment of diabetic retinopathy study (ETDRS). Result: Diabetic retinopathy was present in 12(30%) patients in type 2 diabetes mellitus group and 18(45%) patients in type 2 DM plus hypothyroidism group. In DM plus hypothyroidism patients, Mild nonproliferative retinopathy present in 4 (22.22%) patients, Moderate nonproliferative retinopathy 8(44.44%) patients, severe nonproliferative retinopathy 1(5.5%) patients, Early proliferative retinopathy 4(22.22%) patients and High-risk proliferative retinopathy 1(5.5%) patients.Discussion and conclusion: From present study we can conclude that that prevalence of hypothyroidism was higher among type 2DM mellitus patients in comparison to general population without type 2 DM. Diabetic retinopathy was more common on type 2 DM plus hypothyroidism group then type 2 diabetes mellitus group. We have observed that Moderate nonproliferative retinopathy is more common in both group but early proliferative retinopathy is more common in type 2 DM plus hypothyroidism group then yrs type 2 diabetes mellitus group.
A Study of Point Laser for Automatic Local Road Condition Assessment: Feasibility, Challenges, and Limitations

Road condition assessment plays an important role in maintaining the integrity of mature and fast-expanding road networks. Such assessments provide invaluable information for local authorities that enable them to deliver timely preventative road network maintenance. To enable the best use of scarce maintenance resources, it is necessary to assess the condition of the roads periodically. In this article, we present the Point Laser (PL) system as an alternative approach for automatic road assessment. Compared to current systems, ground penetrating radar and the mobile laser scanning system, the PL system has the advantages of low hardware cost, low computational requirements, and fewer environmental restrictions in relation to its use. The article first outlines the principle of the PL system including a low-complexity signal processing approach. Afterward, the feasibility, challenges, and limitations of the PL system are discussed based on its use in a real environment. A visual-based road survey is used as a ground truth to determine the PL’s performance in relation to the requirements of road condition assessment at various levels of road management. The results of the comparison demonstrate that the PL system is an ideal candidate for the automatic assessment of the condition of local road networks, especially those that require frequent assessment for road asset management.
Dispositifs hyperfréquences et antennes périodiques reconfigurables à base de films minces ferroélectriques des systèmes KTN-KNN

Ce travail concerne la realisation et la caracterisation de dispositifs hyperfrequences agiles en frequence a base du materiau ferroelectrique KTa1-xNbxO3 (KTN) depose en couche mince. Dote d'une permittivite dielectrique elevee (er = 700 a 10 GHz et Ebias = 0 kV/cm), KTN est un candidat prometteur pour la reconfigurabilite et la miniaturisation des dispositifs hyperfrequences. Ses pertes restent neanmoins consequentes (tanδr = 0,3 a 10 GHz et Ebias = 0 kV/cm) et sont en partie a l'origine des pertes globales des dispositifs hyperfrequences realises. Afin de limiter ces pertes, une double approche a ete engagee : (1) reduction des pertes dielectriques par le dopage du materiau KTN par un oxyde a faibles pertes : MgO a 3% et 6% en moles et (2) reduction des pertes globales par le confinement du materiau KTN dope dans les zones actives des dispositifs hyperfrequences. Les couches minces de KTN non dope et dope d'epaisseur ~ 600 nm ont ete deposees sur substrats de saphir oriente R par ablation laser pulse (PLD). Deux compositions differentes (KTa0,5Nb0,5O3 et KTa0,65Nb0,35O3) ont ete selectionnees pour cette etude. Des dispositifs coplanaires imprimes sur les films ferroelectriques ont ete realises et caracterises dans la bande d'interet 1 GHz-20 GHz. Le dopage a 6% assure le meilleur compromis pertes / agilite avec une reduction significative des pertes globales de 0,73 a 0,20 (facteur ~ 4) du dispositif resonant imprime sur KTa0,5Nb0,5O3 apres son confinement par microgravure laser. Une agilite en frequence de 8% est obtenue sous Ebias ≈ 75 kV/cm. L'etude d'une antenne a ondes de fuite reconfigurable en bande Ku a ensuite ete mise en oeuvre. Les couches minces de KTa0,5Nb0,5O3 d'epaisseur ~ 600 nm ont ete deposees par PLD sur substrats de saphir R, puis le materiau ferroelectrique a ete localise par microgravure laser dans les 6 zones actives de l'antenne (constituee de 6 troncons). L’evolution du coefficient de reflexion sous Ebias ≈ 85 kV/cm montre une agilite en frequence egale a 2%. Un gain maximal de 6,7 dBi a ete mesure a f = 17 GHz et Ebias = 0 kV/cm, conformement aux resultats de simulation.
The Influence of Anthropomorphism on Giving Personal Names to Objects

Some people give a proper name to an owned individual object, such as a car or a computer. The study examined whether giving a proper name to a specific object is associated with object personification, and more specifically, whether object personification is a prerequisite to name giving. The latter question was assessed by asking 130 participants whether, in their adult life, they had ever given a personal name to an object, and if so, whether they had attributed psychological characteristics to that named object. The general relationship between personal name giving and personification was assessed by evaluating whether the scores from a questionnaire on anthropomorphism differed in participants who reported having given a specific name to at least one personal object, compared with those who reported not doing so (Mann-Whitney’s U test). Results showed that the scores from the questionnaire on anthropomorphism were significantly higher for participants who had given specific names to objects than for participants who had not done so. However, object personification was not found to be a prerequisite to name giving. Indeed, about 40 percent of people who reported giving personal names to objects did not attribute psychological qualities to these objects.
The influence of technological savviness and home internet access on student decisions to use print or digital course materials

The purpose of this survey research study was to examine Tennessee community college student decisions and experiences with print and digital course material formats. Analysis considered which format students prefer between print or digital, the reasons behind those preferences, and whether those preferences significantly differed based upon demographic characteristics, perceived levels of technological savviness, and/or the availability of home internet access. Students enrolled for the fall 2019 semester at community colleges across the Tennessee Board of Regents system were surveyed using both open-and closed-ended questions ( n = 1,912). Results showed that most students (63.6%) preferred to use print materials, with no significant connections based on demographic characteristics (non-White, low income, age) or home internet access. Student voices woven throughout provided an additional layer of insight for educational leaders seeking to establish policies and practices that optimize the student experience.
Approximation algorithm with constant ratio for stochastic prize-collecting Steiner tree problem

Steiner tree problem is a typical NP-hard problem, which has vast application background and has been an active research topic in recent years. Stochastic optimization problem is an important branch in the field of optimization. Compared with deterministic optimization problem, it is an optimization problem with random factors, and requires the use of tools such as probability and statistics, stochastic process and stochastic analysis. In this paper, we study a two-stage finite-scenario stochastic prize-collecting Steiner tree problem, where the goal is to minimize the sum of the first stage cost, the expected second stage cost and the expected penalty cost. Our main contribution is to present a primal-dual 3-approximation algorithm for this problem.
Please, Do Not Interrupt Me: Work–Family Balance and Segmentation Behavior as Mediators of Boundary Violations and Teleworkers’ Burnout and Flourishing

The lockdown, in the COVID-19 pandemic, is considered an external crisis that evokes innumerous changes in individuals lives. One of the changes is the work and family dynamics. Based on boundary theory we examine the mediated role of work and family balance and boundary segmentation behavior in the relationship between boundary violations and teleworkers’ stress and well-being. However, because women and men live their work and family differently, gender may condition the way teleworkers lead with boundary violations and boundary segmentation. Hypotheses were tested through moderated mediation modeling using data collected of 456 teleworkers during lockdown. In line with our expectations, teleworkers who have suffered most boundary violations were those with least boundary segmentation behaviors and with least work-family balance which, in turn was related to higher burnout and lower flourishing. Furthermore, gender was found to moderate the relationship between boundary violations from work-to-family and segmentation behavior in the same direction and this relationship was stronger for females than for males. We discuss implications for future research and for managing teleworkers, creating sustainability, both during a crise and stable days.
Phase transitions of titanite CaTiSiO 5 from density functional perturbation theory

Phonon dispersion of titanite ${\mathrm{CaTiSiO}}_{5}$ has been calculated using the variational density functional perturbation theory. The experimentally known out-of-center distortion of the Ti atom is confirmed. The distortion is associated with a ${B}_{u}$ mode that is unstable for wave vectors normal to the octahedral chain direction of the $C2/c$ aristotype structure. The layer of wave vectors with imaginary mode frequencies also comprises the Brillouin zone boundary point $Y$ $(0,1,0)$, which is critical for the transition to the $P{2}_{1}/c$ ground-state structure. The phonon branch equivalent to the imaginary branch of the titanite aristotype is found to be stable in malayaite ${\mathrm{CaSnSiO}}_{5}$. The unstable phonon mode in titanite leads to the formation of transoriented short and long Ti-O1 bonds. The Ti as well as the connecting O1 atom exhibit strongly anomalous Born effective charges along the octahedral chain direction [001], indicative of the strong covalency in this direction. Accordingly and in contrast to malayaite, LO-TO splitting is very large in titanite. In the $C2/c$ phase of titanite, the Ti-O1-Ti distortion chain is disordered with respect to neighboring distortion chains, as all chain configurations are equally unstable along the phonon branch. This result is in agreement with diffuse x-ray scattering in layers normal to the chain direction that is observed at temperatures close to the $P{2}_{1}/c$ to $C2/c$ transition temperature and above. The resulting dynamic chains of correlated Ti displacements are expected to order in two dimensions to yield the $P{2}_{1}/c$ ground-state structure of titanite.
The fruit metric trait characterization of scarlet eggplant using the high-throughput tomato analyzer software

Scarlet eggplant (Solanum aethiopicum [L.]) is an indigenous, underutilized fruit vegetable in Africa. Preference for fruit shape and size is high among growers and consumers. Fruit metric traits are important for yield improvement. Fruit metric descriptors are important contributors to variation, phenotypic and genotypic variation, and heritability. However, the measurement of these traits is cumbersome and subjective. Forty-three accessions were evaluated in 2016 and 2017. At maturity, 5 fruits were randomly harvested from each accession, digitalized and processed using the Tomato Analyzer software. Sixteen fruit metric traits were automatically generated and submitted for analysis of variance and multivariate analysis. The accessions differed over fruit size and shape due to genetic make-up. Fruit metric trait variation among S. aethiopicum groups was less influenced by the environment. The cv. Gilo group has oblong fruits, the cv. Shum group fruits are circular and ovoid; the cv. Kumba group fruits are less circular, lobed and flattened. AE/113 (C3), FUO 1 (C1) and FUO 5 (C2) Gilo groups are promising for fruit size. There were phenotypic plasticity and overlapping for fruit metric traits between the Gilo and Shum groups due to a common genome. The Tomato Analyzer software was able to discriminate accessions based on fruit phenomic traits, and the information could be used to establish commonalities between groups.
Cobalt oxide nanosheets anchored onto nitrogen‐doped carbon nanotubes as dual purpose electrodes for lithium‐ion batteries and oxygen evolution reaction

Transition metal oxides (TMOs) have been extensively explored as promising electrode materials for electrochemical energy storage and catalysis. However, TMOs intrinsically have low electronic conductivity and suffer severe volume change during electrochemical cycling. In this study, we develop an effective strategy to enhance conductivity and buffer volume changes of TMOs, in which networked nitrogen‐doped carbon nanotubes (N‐CNTs) are incorporated into Co3O4 nanosheets system. Based on the whole mass of Co3O4 and N‐CNT, the composites can maintain a stable discharge capacity of ~590 mAh g−1 after 80 cycles at a current density of 0.5 A g−1. Moreover, the composites also exhibit greatly enhanced catalysis ability towards oxygen evolution reaction (OER), ie, small Tafel slope of 84 mV dec−1, low overpotential of 310 mV at a current density of 10 mA cm−2, and almost no activity decay throughout 30‐hour continuous operation. This study lays a new route for smartly designing advanced electrode materials for energy storage and electrochemical catalysis.
