Published: July 2022

Objectives:

Delay in the diagnosis of pulmonary tuberculosis (TB) is reportedly common in Nigeria. This results in delayed initiation of treatment and increased spread of the disease. This study assessed diagnostic delay and its influencing factors among pulmonary TB patients who were attending directly observed treatment clinics in Osogbo, Nigeria.

Materials and Methods:

This descriptive cross-sectional study was carried out from August to October 2019 in 10 directly observed treatment clinics in Olorunda Local Government Area, Osogbo, Osun State, Nigeria. Multistage random sampling was used to select 280 registered TB patients. Data were collected using an interviewer-administered semi-structured questionnaire and analyzed with Statistical Package for the Social Sciences version 23.

Results:

Most respondents, that is, 220 (80.3%) were Yoruba, 69 (25.2%) had tertiary education, and 53 (19.3%) had no education at all. Only 135 (49.3%) respondents had good knowledge of pulmonary TB. We found that 157 (57.3%) respondents had patient-related diagnostic delays, while 135 (49.3%) had health system-related delays. Median patient-related delay was 1 month, while median health system-related delay was 3 weeks. There was no significant association between patient-related delay and any sociodemographic characteristic, knowledge about TB, or perceived attitude of health care workers. A significant difference in health-system-related delay was found concerning the attitude of health care workers toward patients (P = 0.043) and patients’ religion (P = 0.030), and level of education (P = 0.001).

Conclusion:

While pulmonary TB is common in the lower socioeconomic class, health workers should be open-minded while evaluating all patients to ensure correct and prompt diagnosis. A good attitude of health workers towards patients is important for preventing diagnostic delays.

Interfaces are key elements that define electronic properties of the final device. Inevitably, the active interfaces of III-V semiconductor devices are buried and it is therefore not straightforward to characterize them. The Tapered Cross-Section Photoelectron Spectroscopy (TCS-PES) approach is a promising method to address such a challenge. For the first time, we demonstrate the TCS-PES on III-V architectures. A MULTIPREPTM polishing system that enables controlling the angle between the sample holder and the polishing plate has been employed to improve reproducibility of the polishing procedure. With such equipment, we demonstrate that preparing the TCS of III-V semiconductor devices with tapering angles lower than 0.02° is possible. The TCS-PES provides then information about the buried interfaces of Ge|GaInP and GaAs|GaInP layer stacks, prepared by metalorganic chemical vapor deposition (MOCVD). Both, chemical and electronic properties have been measured by PES. It evidences that the preparation of the TCSs under an uncontrolled atmosphere modifies the pristine properties of the critical buried heterointerfaces. Surface states and reaction layers are created on the TCS surface, which restrict unambiguous conclusions on buried interface energetics.

Published: July 2022

The representation of molecular structures is crucial for molecular machine learning strategies. Although graph representations are highly versatile and show their broad applicability, they lack information about the quantum-chemical properties of molecular structures. This work proposes a new way to infuse such information into molecular graphs, using a supervised learning method. As a result, the model is able to predict essential higher-order interactions between electron-rich and electron-deficient localized orbitals. The learned interactions are then used as a representation for the prediction of downstream tasks, improving over QM9 baselines.
A dual-role halogen-bonding-assisted EDA-SET/HAT photoreaction system with phenol catalyst and aryl iodide: Visible-light-driven carbon–carbon bond formation
Authors: Uchikura Tatsuhiro , Tsubono Kazushi , Hara Yurina , Akiyama Takahiko
Published: July 2022

Electron donor–acceptor (EDA) complex-mediated single-electron transfer (SET) is a crucial method for generating carbon radicals. Hydrogen atom transfer (HAT) enables the direct generation of alkyl radicals from alkanes. We report a dual-role EDA-SET/HAT photoreaction system for carbon–carbon bond formation using a phenol catalyst and aryl iodide. This system facilitates a Minisci-type addition of alkyl radicals to arenes. Mechanistic studies revealed that EDA complex formation is mediated by halogen bonding between phenoxide and aryl iodide. Irradiation of the EDA complex with visible light generates an aryl radical, which abstracts a hydrogen atom from an alkane to form an alkyl radical.

Herein, we provide an approach towards a Lewis acid-containing analogue of the bulky diphosphine, 1,2-bis(di-tert-butylphosphino)ethane that contains a single boron moiety. The coordination chemistry of this ligand and its allyl precursor have been explored using nickel(0).
Affinity for Anions Developed in Charcoal by Acid Treatment
Authors: Long Leonel Andrés , Arnal Pablo Maximiliano
Published: July 2022

In this study, we report a two-step method that creates at the surface of charcoal acidic groups that remove nitrate from an aqueous solution. The process used in this work with charcoal includes first an acid treatment followed by a heat treatment in a non-oxidizing atmosphere —a simple method to perform this treatment in a standard laboratory furnace is additionally presented—. As a control group, we use a process that omits the acid treatment and includes only the heat treatment. The precursors and products of the investigated processes were characterized in terms of (a) surface chemistry (zero charge point, Boehm titration), (b) structure (scanning electron microscopy, X-ray diffraction, nitrogen adsorption, Hg porosimetry), and (c) composition (CHN elemental analysis, thermal gravimetric analysis, Energy Dispersive X-ray Fluorescence). Acid-thermal treatment of charcoal creates Lewis acid groups that remove nitrate anions from an aqueous solution. The nitrate-removing Lewis acid groups were absent in the starting material as well as in the material obtained in the control group. The creation of these surface groups occurs without significant damage to the macropore structure of the charcoal particles. A simple process can generate chemical groups with an affinity for anions in an aqueous solution on the charcoal surface.
tained glass from the research of the Dubrovnik cathedral | Slikano steklo odkrito med raziskavami dubrovniške katedrale
Authors: Nikolina Topić
Published: July 2022

The Dubrovnik Republic maintained its own glass production in the late Middle Ages, including records of window glass manufacturing. This paper will contribute to the study of stained glass in the Balkan region. It will outline late medieval stained-glass fragments (mid-14th to the first half of the 15th century) excavated from the Dubrovnik cathedral during the renewal of the building after a large earthquake in 1979 and are extremely rare in the Balkan region. Analogous examples of Dubrovnik archaeological material can be found among Western European stained-glass windows. These finds indicate that Dubrovnik was influenced by Western European technology through trade or that this way of making stained glass began to be applied in local workshops.

The Anti-Cancer Effect of Strained Photoactivatable Polypyridyl Ruthenium(II) Complexes on Non-Small-Cell Lung Cancer and Triple Negative Breast Cancer Cells. (c2020)
Authors:   ,   Lebanese American University, Fayad Christelle
Published: July 2022

Ruthenium complexes have been recently reported as potential chemotherapeutic agents that offer tumor selectivity and low tumor resistance. Photoactivated chemotherapy consists of introducing a ‘prodrug’ that dissociates into toxic molecules upon light activation. The present study investigates the effect of four synthesized photoactivatable ruthenium II complexes on lung cancer (A549) and breast cancer (MDA-MB-231) cells. These compounds are [Ru(bpy)2dmbpy]Cl2 (C1), [Ru(phen)2dmbpy]Cl2 (C2), [Ru(BP)2dmbpy]Cl2 (C3) and [Ru(BPS)2dmbpy]Na2 (C4). Cultured cancer cells were treated with the above complexes for 12 h and then irradiated with blue light for 30 min. Cell viability was then evaluated using WST-1, 72 hours post treatment. The cellular uptake of various complexes at different time points was assessed using LC-MS/MS. Results showed that upon photoactivation, C3 exhibited the highest cytotoxicity (MDA-MB-231, IC50 = 0.73μM; A549, IC50 = 1.26 μM) which correlated with the high cellular uptake. The phototoxicity indices (IC50 dark/IC50 light) of C3 were 6.56 and 4.64 for MDA-MB-230 and A549 respectively. Determination of the octanol-water partition coefficient (log P) of the various complexes revealed that C3 is the most lipophilic which justifies its high cellular uptake and high cytotoxicity. ROS detection by DCFDA staining showed that upon treatment with C3 and C4, MDA-MB-231 produced high ROS levels that could have initiated cell death. Cytotoxicity against mesenchymal stem cells (MSCs) was assessed on the most effective compound C3 which exhibited minimal toxicity on MSCs in dark (IC50=74 μM vs 4.72 and 6.03 in A549 and MDA-MB-231 respectively) but comparable toxicity to cancer cells in light (0.9 μM). Flow cytometry using Annexin/PI staining revealed a significant increase in early and late apoptotic MDA-MB-231 cells upon treatment with C3. Western blot analysis on MDA-MB-231 cells treated with C3 showed a significant increase in BAX/Bcl2 ratio with no significant effect on Pro-caspase-3 expression. In conclusion, C3 was shown to be a potential selective photoactivatable chemotherapeutic complex that induces apoptosis through a caspase-3 independent intrinsic pathway.

This paper analyses sport passion as a possible determinant for sport consumption. The purpose of this research, after defining the concept of passion for cycling, is to understand the existing relations between the latter and the costs incurred to practice this sport at an amateur level. This research is exploratory in nature and uses a qualitative mix-method approach. Given the need to isolate individual dynamics of cyclists from socio-cultural influences, the interviewees were selected from a restricted and homogeneous geographical area: the Umbria Region (Italy). The study is structured in two phases: in the first phase 22 in-depth interviews were carried out; in the second phase a group interview was preferred. In order to guarantee transparency e verifiability of the results, the answers were handled with the help of a word processing software (NVIVO). The results of this research suggest that cyclists’ consumption models are instrumentally influenced by the passion for cycling, more than other characteristics previously studied in sport management literature. This study provides useful indications on how to develop new forms of market segmentation. It also offers an approach for the operationalization of the level of passion for cycling, which enriches the current equipment of sports management researchers, who can also use the work in other contexts of free time consumption. This work highlights the key role of passion as a determinant for sport consumption and represents an original connection between psychological studies on sport passion and economic studies on sport consumption.

Equine-facilitated activities (EFA) are generally considered to be an alternative treatment method by using the natural body form, gait and behavior of horses. EFA have been used for many years to treat and to improve the living conditions of people with disorders or disabilities such as autism, cerebral palsy (CP), arthritis, multiple sclerosis, stroke, spinal cord injury, behavioral and psychiatric disorders. This study aims to examine the effects of adaptive riding (AR), which is a subdiscipline under EFA, on anxiety, empathy, aggression, and emotional regulation of children diagnosed with cerebral palsy. Maternal depression and anxiety level measurements were also included in the study. Twenty children with CP, between 7 and 10 years old and their mothers participated in the study. They were randomly assigned to one of two groups (intervention and control) consisting of 10 participants. Pre and post measurements were implemented at the beginning and at the end of 8 weeks of AR intervention. The Screen for Anxiety Related Emotional Disorders, Bryant Index of Empathy Measurement for Children and Adolescents, Buss-Perry Aggression Questionnaire, Beck Depression Inventory, The State-Trait Anxiety Inventory were used to measure the psychological and emotional status of the participants and depression, anxiety levels of mothers. Aggression, anxiety, and maternal depression decreased; empathy and emotional regulation improved in the intervention group. No significant differences found in the control group. This study provides strong evidence that an 8-week AR intervention has positive effects on children with cerebral palsy. Significant improvements regarding both maternal and children’s psychological and emotional aspects showed how an alternative therapy with animals can be constructive.

Since all activities in handball should be performed as fast and as powerful as possible, power is involved in almost all players’ movements. There is an evident lack of studies that monitored this ability during matches. The study aimed to determine the situational differences in power among playing positions in top-level female handball. Variables included: body height, average game time, fastest shot, fastest sprint, and highest jump. Subjects were 227 female handball players that participated in the European handball championship 2020. Analysis of variance with the post-hoc Scheffe test was calculated. Results showed significant differences among playing positions in body height, fastest sprint and highest jump performed in real game situations. The largest differences were noticed in anthropometrics, with significant differences between back- and pivot-players on one side, and wing-players on the other. The fastest sprinting was recorded for wingers (26.5±1.12 km/h), who were significantly faster than other players. Jumping performance was most diverse among playing positions, with back-players being superior in this performance (47.24±17.61 cm, 48.44±20.71 cm, and 50.35±16.76 cm for centre-backs, leftbacks, and right-backs, respectively). Evidenced differences are explainable knowing the specific positions’ roles and typical game situations which players encounter during the match.

This study aimed to examine the effect of high protein from chicken breast products during resistance exercise training on muscle mass and strength in healthy Thai male volunteers. In this study was double-blind randomized placebo-controlled study. This study assessed changes in muscle mass and strength of 60 healthy men aged 20-35 years with normal BMI (23.04±2.52 kg/m2). Participants were randomly divided into three groups receiving controlled placebo tablet (CG, n=18, lactose-based containing 12.0 g lactose/day), chicken tablet (CT27, n=18, 27.0 g protein/day), and chicken chip (CC36, n=19, 36.8 g protein/day) during 69-day period. In addition, all groups were instructed to perform the same resistance training program (4 times per week). Body composition (BIA), anthropometry (AMC, CMC), and muscle strength were measured. After 9 weeks of the study, CC36 group had a statistically significant increase (p<0.05) in the percentage of skeletal muscle from baseline when compared other two groups. Additionally, a significant increase (p<0.01) in arm muscle circumference, back-leg extension, and hand grip strength were observed in both groups receiving chicken protein products. The same result was also detected in the placebo group but at a much slower rate. Resistance training exercise along with intake of the chicken protein products could increase muscle mass and strength.

Sprint is essential for successful sport performance. Acceleration is necessary for every position in football. The ability to successfully accelerate is also an important determinant for more carried gaming activities. The eccen- tric strength of the hamstrings is an important task in sprint. The aim of our study was to test the correlation between the 30 m sprint and the eccentric strength of the hamstring by NordBord. The sample consisted of 48 professional football players (23.15±4.78 yr.; 180.5±5.42 cm; 76.5±7.94 kg) of the highest Slovak football league. The correlation between 30 m performance and average eccentric hamstring strength has been -0.0826. The correlation suggests that the sprint speed and eccentric strength of the hamstrings have not been associated 0 (t=-0.5619; df=46; p=0.5769). Correlation between 30 m performance and AVG/kg was -0.1317, indicating that the correlation between average weight and speed was not been significant. The eccentric strength has not been associated with a higher speed in the 30-m sprint test. However, more intervention studies are warranted.

一种隧道初支仰拱拱架与下台阶拱架连接方式探讨——以中 条山隧道施工为例
Authors: 海刚 王
Published: July 2022

传统的初支仰拱拱架和下台阶的连接方式，存在下台阶拱脚处开挖困难，难以按照设计轮廓线开挖成型，超挖严重；封闭成环后，拱脚处已不是受力主要部位，受力主要集中在连接处的螺栓上，易造成断裂；且连接处以下的拱架和脚板冗余，易造成喷浆不密实。隧道初支仰拱拱架与下台阶拱架连接方式将连接位置由下台阶侧面改进到下台阶底部，开挖轮廓变成圆弧形，有利于超欠挖控制；受力均匀分布在拱架上，避免应力集中造成连接处断裂，提高了初支的稳定性；减少连接处冗余的拱架和脚板，既节约了成本，又有利于喷浆密实度控制。

La Gran Recesión y el Pensamiento Económico Heterodoxo: Un Debate Abierto
Authors: Orozco-Suárez Christian Rafael
Published: July 2022

En 2008 Estados Unidos se convirtió en el epicentro de una de las mayores crisis económicas que se recuerdan desde la Gran Depresión de los años treinta del siglo XX. Múltiples y variadas fueron las interpretaciones económicas que se plantearon para intentar explicarla. En esta investigación se presentan las principales aportaciones que desde las distintas escuelas de pensamiento económico heterodoxo se han formulado, a saber: corrientes marxista, poskeynesina y regulacionista. La metodología aplicada para ello consiste en un análisis pormenorizado de la obra: Radical Economic Theories of the Current Economic Crisis (Preparada para la Conferencia URPE-Occupy Summer, en Agosto de 2012). En este sentido, este artículo considera que existen tres tipos de explicaciones a la crisis desde las escuelas heterodoxas, vinculadas específicamente con: i) el comportamiento del sector financiero; ii) la desigualdad económica y social; y, iii) el comportamiento del sector productivo.

La diversidad de pensamientos relacionados con el saber teórico y las prácticas políticas económicas, los descubrimientos en el campo del análisis económico, la intervención de la nuevas tecnologías, la estadística, y las nuevas técnicas para seguimiento de las economías, no han lograron que las discrepancias se eliminen; en la actualidad existen grandes fallos en el mercado. Los gobernantes en Ecuador fueron y son elegidos por simpatía, la mayoría de los votantes no analizan el plan de gobierno que cada elector debe presentar durante su candidatura e inicio del primer año de gestión. Por otro lado, el continuo cambio de ideologías, iniciando cuando el Estado no debe intervenir en el mercado suponiendo que las cosas se mejorarían por sí solas (política neoliberal); y posteriormente, cuando el Estado decide intervenir en el mercado, creando una economía artificial (política neokeynesiana). Este estudio se fundamentó en una investigación analítica de base documental, usamos como método de investigación el inductivo, analítico y de síntesis. Obteniendo como conclusión que en el Ecuador no se observa una política definida, lo que diríamos que esta se aplica según la conveniencia de las autoridades nominadas.
El Financiamiento de las Pymes, Rubro Centros Turísticos Recreacionales, Sullana, Piura-Perú, 2016
Authors: Jurado-Rosas Adolfo Antenor
Published: July 2022

La presente investigación tiene como objetivo determinar y describir el financiamiento de las micro y pequeñas empresas del rubro centros recreacionales, de la ciudad de Sullana, a partir del desconocimiento de los propietarios de las fuentes y facilidades para acceder al financiamiento. El método utilizado es de carácter descriptivo, con un enfoque cuantitativo de corte transversal de tipo no experimental. A modo de conclusión, debido a los factores climáticos que se presentan en la región norte del Perú como es el fenómeno de El Niño, los empresarios son reacios a asumir riesgos inherentes al financiamiento a largo plazo, debido a las experiencias de periodos anteriores y en que sus ingresos se vieron afectados de manera importante, ya que este fenómeno se presenta entre los meses de octubre y abril, periodo en el cual por ser verano en la región existe una mayor demanda del servicio ofrecido. Debido a ello se afectarían los flujos de caja, los cuales elevarían el costo financiero ante el incumplimiento de los cronogramas de pago en caso que se acceda a un crédito por parte de una entidad bancaria o caja de ahorro a largo plazo.

Published: July 2022

A havannai USA nagykövetségen dolgozók között 2016-ban újszerű, furcsa panaszok jelentkeztek. A dolgozók egy része erős fejfájásra, hányingerre, vibráló érzésre panaszkodott, amelyet egy igen erős hangingert követően észleltek. A tünetek enyhültek ugyan helyzetváltoztatásra, másik szobába történő áthaladásra, de az akut tünetek után krónikus panaszok jelentkeztek. A sokszor állandósuló fejfájás mellé memóriazavar, hallás- és látásproblémák, kognitív és pszichés zavarok társultak. Részletes kivizsgálásuk repatriálásukat követően az USA egyetemi kórházaiban zajlottak, ahol neurológiai, neuropszichológiai elváltozások voltak rögzíthetők, amelyet képalkotó vizsgálatok is megerősítettek. A tünetegyüttest Havanna szindrómának nevezték el, azóta azonban Kínában, az USA felségterületén, és legutóbb Ausztriában is előfordultak ilyen panaszok a diplomaták és a hírszerző közösség tagjai között. A tünetek hátterének felderítésére széleskörű egészségügyi, igazságügyi és hírszerző vizsgálat indult. Az Amerikai Egyesült Államok Külügyminisztériuma megbízásából az esetekről összefoglaló jelentést készített az Amerikai Mérnöki, Tudományos és Orvosi Akadémia tagjaiból álló munkacsoport. Megállapításuk alapján a tüneteket legvalószínűbben egy fókuszált, alacsony energiájú, pulzatilis rádiófrekvenciás besugárzás, szándékolt támadás okozhatta. A sugárzás okozta egészségügyi következményeket, a lehetséges egészségügyi és átfogó jellegű beavatkozásokat ismertetem a cikkben.

Authors: Faihan Basma Abdulsahib , Al-Dahan Ziad , Alzubeidy Hussein
Published: July 2022

Non-dispersive near-infrared technique is widely used nowadays for the detection of gases, especially in harsh environments. In this study, an optical gas cell was designed for oxygenator exhaust capnometry. A computer-based simulation was used for the analysis of air flows for model selection. ANSYS Discovery 2020 R2 was used for model simulation. The gas flow cells were tested using a custom-made gas rig to measure the fraction absorbance of carbon dioxide gas at the detector. Two gases were used, nitrogen gas as a reference gas (0%) and 9% carbon dioxide. Three gas cells with the following optical path lengths were tested: 31mm, 36mm, and 40mm. The results showed that all gas flow cells produced laminar flow and small pressure drop across the inlet and outlet of the cell (11~12 Pa). Further, the minimum velocity is obtained in the 40mm gas flow sensor and it is located at the gas outlet path away from the effective optical gas path. The simulation and experimental results indicate that the gas flow cell of 40mm optical path length is more suitable for the intended application as it offers a maximum effective absorption path compared to the stagnation areas, and as a result, it provides the maximum fraction absorbance.
