Functionalized moso bamboo powder adsorbent for Cd(II) complexes with citric acid/tartrate acid: characterization, adsorptive performance, and mechanism
Authors: Sun Qinju , Lin Shaohua , Liu Guohua , Xuan Yue , Gao Liping , Li Pingping
Published: November 2021

A new amine group functionalized moso bamboo powder adsorbent (AMBP) was prepared using a facile procedure to remove Cd(II) complexes with citric acid (CA) and tartrate acid (TA). The properties of the AMBP were characterized using SEM, FTIR, XPS, BET, and an elemental analysis. The adsorptive performances of the AMBP toward Cd(II)-CA/TA were investigated. The results indicated that amine group was successfully introduced, and the AMBP with a BET specific surface area of 0.463 m2/g was effective in adsorbing Cd(II)-CA/TA under pH 4.0–10.0. The removal of Cd(II) increased significantly when the Cd(II)/ligand molar ratio changed from 1:0.5 to 1:2. The adsorption processes of Cd(II)-CA/TA were endothermic and fit well with the pseudo-second-order kinetic model (R2 > 0.999). The Langmuir model (qmax of 14.41 and 7.58 mg/g for Cd(II)-CA and Cd(II)-TA, respectively) fit the isotherms better than the Freundlich model. The AMBP could be regenerated by HCl and reused at least 4 times. The uptake mechanisms of Cd(II)-CA/TA were proposed to be physisorption and the chemisorption of the coordination between –NH2/–NH and the Cd(II). This work shows that the AMBP is an adsorbent with high practical value to remove Cd(II) in water or wastewater containing CA/TA.
High Efficient Resonant DC-DC Converter for Automotive LED Driver Applications using Phase Shift Control Strategy
Authors: Syed Simran.K, Md.Anwar, Dr.Sharan Reddy and Santosh.B.M
Published: November 2021

A high frequency DC-DC converter operating in the MHz range is proposed, which can achieve unbiased load current even
while maintaining high performance over a wide range of load voltages. Due to these functions, the provided transformer is
suitable for LED driver applications, which require different types of LEDs to operate with controlled current. The proposed
transformer satisfies the uncontrolled load current using the LCL-T resonance community and achieves high efficiency using a
predetermined switching frequency. The LCL-T resonance transformer also works effectively in controlling its output to the
required rating using phase shift control. The overall performance of the LCL-T Echo transducer was evaluated and compared
with the LC3L controlled echo transducer. Simulation work is done using the MATLAB / Simulink program.

Study of Modulation Schemes over a Multipath Fading Channels
Authors: Allanki Sanyasi Rao and Kallepelli Srikanth Karthik Kumar Vaigandla,
Published: November 2021

Communications systems concerted over wireless channels depend on the environment. Communications system can be more
reliable and efficient by properly analyzing wireless channels. Today's most important features are a high data rate and reliable
performance to exploiting viable networks during this new information age. The channel is not time-invariant in wireless
communication, so the received signal exhibits amplitude, phase, and angle variations due to multipath fading. Increasing data
rates and reducing bandwidth make Orthogonal Frequency Division Multiplexing (OFDM) an important component of wireless
communication systems. The OFDM technique uses many carriers very efficiently. With this scheme, interference is robustly
reduced, and fading scenarios are easily accommodated. Analyzing digital modulation schemes requires evaluating link
performance with fading channels. The paper compares channel performance over varying fading environments using a variety
of modulation schemes. We study the BER and SNR properties of the AWGN, Rician fading and Rayleigh fading channels
modulated with BPSK, QPSK, and M-ary QAM.

better survival? A systematic review
Authors: Lee Kai-Yin , Lau Jerrald , Siew Bei-En , Chua Yong-Kang , Lim Yi-Xuan , Lim Xin-Yi , Chong Choon-Seng , Tan Ker-Kan
Published: November 2021

ABSTRACT
Introduction: Surgical resection of the primary and metastatic tumour is increasingly recommended
in suitable patients with metastatic colorectal cancer (CRC). While the role of metastasectomy is well
studied and established in colorectal liver metastasis, evidence remains limited in pulmonary metastases.
This systematic review was conducted to examine the current evidence on the role of lung metastasectomy
(LUM) in CRC.
Methods: Three databases were systematically searched, to identify studies that compared survival
outcomes of LUM, and factors that affected decision for LUM.
Results: From a total of 5,477 records, 6 studies were eventually identified. Two papers reported
findings from one randomised controlled trial and 4 were retrospective reviews. There was no clear survival
benefit in patients who underwent LUM compared to those who did not. When compared against patients
who underwent liver metastasectomy, there was also no clear survival benefit. Patients who underwent
LUM were also more likely to have a single pulmonary tumour, and metachronous disease.
Conclusion: The evidence suggests a role for LUM, but is limited by inherent selection bias in retrospective
reviews, and the single randomised clinical trial performed was not completed. More prospective studies
are required to understand the true effect of LUM on outcomes in metastatic CRC.

The Influence of Digital Money on Economic Growth in Kenya
Authors:   Post Graduate Student, School of Business, Jomo Kenyatta University of Agriculture and Technology, Kenya., Ramos Patrick Kioko
Published: November 2021

The growth of the economy is a concern to many because it has an influence on the progress of a country and its citizens. It is expected that an economy with a highly advanced digital money system should also experience high economic growth. However, statistics indicate that the economic growth rate in Kenya has been fluctuating and has failed to grow consistently despite numerous policy interventions. This study sought to establish the influence of digital money on Economic Growth in Kenya. The study incorporated a descriptive research technique and a time series approach to analyse the relationship between digital money and economic growth using Kenyan quarterly data from 2011 to 2020. Four variables were used as proxies to measure digital money: - the value of mobile money transactions, the value of cards money transactions, the value of internet banking (EFTs) transactions and agency banking. The findings revealed that all relationships that were tested were positive and significant each with p-Value that was less than 0.05. Further analysis showed F-Calculated (1, 38; α=0.05) was 32.909 (card transactions), 247.029 (EFT transactions), 297.118 (mobile transfer), and 571.417 (active agents). Therefore, the study recommended that there is need for an intensified campaign to sensitize the public on the importance of digital money owing to their flexibility and improved security as compared to carrying physical cash especially in the wake of the COVID-19 pandemic. To the policy makers, the findings suggest that there is need to solidify and enforce strong digital/ICT policy that promotes cashless payments.

Genital-pelvic pain / penetration disorder (DGPP) includes vaginismus, dyspareunia and vulvodynia, where the following symptoms are present: Presence of fear or anxiety related to vulvovaginal or pelvic pain in anticipation, during or as a result of vaginal penetration, in addition to the presence of tension or hardening of the pelvic floor muscles during the attempt of vaginal penetration. Adequate sexual function is considered an important factor for quality of life, being recognized by WHO (World Health Organization) regarding the presence of sexual dysfunction as a public health problem, recommending its investigation for causing important changes in quality of life and in the relationship with your partner. It is identified that the role of the physiotherapist becomes relevant in the process of identification and rehabilitation of genito-pelvic pain, justifying the importance of studies on this topic. In order to analyze the role of the physiotherapist in the treatment of pelvic genital pain / penetration with a focus on the approach of manual therapy in women at menacme, a narrative review of the literature was carried out, where 17 articles were used as a basis for research and data collection. During the analysis of the articles, it was defined that DSFs tend to appear in the female fertile phase, causing pain and discomfort. In the reviews covered in this study, it was analyzed that DGPP is a complex syndrome in which the sensation and intensity of pain are felt in different places. With this the diagnosis becomes difficult taking into account the shame and / or blocking of the woman in reporting a sexual complaint. Through a physical therapy assessment, in order to check the tone and function of the pelvic floor muscles, the existence and location of tender points, as well as the understanding of voluntary contractions and rests of these muscles, a therapeutic planning with the use of interventions is outlined. specific measures in self-relaxation and anxiety control techniques, improving body awareness. It is concluded that there is effectiveness in exploring self-knowledge to improve the quality of life of women who suffer from this problem, providing positive results in a short period, thus contributing to the improvement of the sexual function of women with DSFs (Female Sexual Dysfunctions).

Published: November 2021

The United States’ Farm-To-School Program (F2SP) is a competitive grant program that targets participants of the National School Lunch Program and School Breakfast Program with the aim of increasing the quantity and frequency of locally sourced fruits and vegetables offered to children during the school year. This narrative review aims to summarize the outcomes of the F2SP’s interventions on child health and wellness using the research available to date and provide points to consider when implementing the F2SP outside of the United States, particularly in Egypt and Morocco. Analysis of the existing literature showed that both Egypt and Morocco have been beneficiaries of their aid and have seen improvements in the number of children receiving meals at school. With its centralized school meals system, and with support from the World Food Programme (WFP), Egypt has the infrastructure to set up and sustain a long term F2SP that will enrich local communities, grow local economies, and support the health of the next generation. As the WFP continues its work in Morocco, the focus should be maintained on developing a strong school meals system and addressing immediate food insecurity. The viability of such a program being implemented should be reassessed once outcomes from current hunger relief efforts become available. Additional research is needed to continue to study the feasibility, applicability, and impact of this program, especially as it would be applied in areas with no centralized school meals programs across North Africa.

Laboratory instruments are commonly equipped with communication interfaces (e.g., GPIB, USB or LAN port) for data acquisition or control through a computer. However, such interface might not be available on handheld equipment, e.g., multi-meters, where readings have to be taken manually by operators during calibration. To improve efficiency and reduce possible human errors, SCL has developed an automatic meter reading system for seven segment displays using deep learning techniques.
Development of a Universal Measurement Process Framework
Authors:   Fluke Corporation, Brown Michael
Published: November 2021

Calibration software has largely been developed with a direct measurement comparison method at the forefront. While adequate for many routine calibration processes, over time this approach becomes insufficient for more complex calibrations and often leads to the creation of special tests, add-ons, and various types of workarounds which are neither ideal nor sustainable over the long term. In some cases, these inadequacies initiate the development of a completely new and separate calibration software designed to specifically address a single calibration discipline or measurement problem. This paper discusses a complete and universal measurement process framework which is not only capable of accommodating routine and complex calibration scenarios alike, but also allows the use of various comparisons such as direct, indirect, ratio, differential, transfer, and substitution measurement comparison techniques. Additionally, the framework generates a comprehensive set of records to include; all original observations, calculations, corrections, conversions, environmental factors, and measurement results, allowing for step-by-step auditing of every measurement performed. Although primarily intended for use within calibration software which can facilitate automated, semi-automated, and manual calibrations - this approach may also be utilized entirely outside of software in any calibration scenario
Industrial Solar Simulator Calibrator based on special solar module
Authors:   CENAM, Garcia Gonzalez Alexis
Published: November 2021

Mexico is currently emerging in the photovoltaic manufacturing market due to favorable geographical conditions like 5.5 hours of sun every day (5000W/m2) and a strategic commercial partner (USA) for exportation of photovoltaic products, therefore a gradual advance in the photovoltaic field as a source of clean energy generation in Mexico is inevitable, this causes a need to classify solar simulators located in photovoltaic manufacturing facilities across the whole country. The construction of a standard for the classification of large area solar simulators in non- uniformity irradiance (MMNU) was achieved, considering specifications of the international standards IEC90604-9 and IEC90604-2. The procedure for using this MMNU substantially improves the classification time of a large area solar simulation and its versatility of use in an industrial environment, resulting in suitable on-site measurements. The MMNU is composed of six electronic reading circuits and 36 cells which are connected individually, it can generate an irradiance map up to 72 regions and the measurement uncertainty within the operating temperature conditions of 29 C to 31 C was 1.1 % using the mathematical expression for non-uniformity in the standard IEC90604-9. Various strategies have been outlined to reduce the measurement uncertainty of the entire system, like reducing its thermal drift during measurement and improving the measurement uncertainty in electrical voltage by creating a new electronic reading module that would include a more robust microcontroller and A/D converter with higher resolution.

Sandia’s Uncertainty Calculator: A Case Study in the Graded Approach to Software Quality Assurance
Authors:   Sandia National Laboratories, Delker Collin
Published: November 2021

Where practicable, the total end-to-end test-and-calibration program cost would serve as the ultimate measurement quality metric (MQM). Total cost includes both the capitalization and ongoing costs that support product quality (sometimes called cost of quality) and the consequence costs (sometimes called cost of poor quality) that result from imperfect measurement and products. End-to-end means capturing costs from the entire traceability chain: from measurement standards to end products. Minimizing this MQM, total end-toend cost (TETEC), equates to optimizing measurement quality assurance (MQA). Lacking easily available measurement and performance data automatically fed to modeling software, organizations have found cost metrics unimaginable or impracticable, so their measurement programs instead target more easily computed MQMs, such as false-accept risk or simpler proxies thereof, setting minimum, but sub-optimal, quality levels. However, modern computing systems and software, such as laboratory management systems with testpoint- level traceability, rapidly approach the point at which the TETEC MQM will become practicable. Preparing for this eventuality, the NCSLI 173 Metrology Practices Committee has developed models that relate costs to measurement program information such as product specifications, test and measurement uncertainties, calibration intervals and reliability targets. Applications include optimizing overall program MQA, but also estimating the value of metrology and return on equipment investments, selecting instruments, designing test and calibration processes, designing products. This paper applies the cost models to case studies and examples to illustrate some applications.

Abstract. Ocean mass change is one of the main drivers of present-day sea-level change (SLC). Also known as barystatic SLC, it is driven by the exchange of freshwater between the land and the ocean, such as melting of continental ice from glaciers and ice sheets, and variations in land water storage. While many studies have quantified the present-day barystatic contribution to global mean SLC, fewer works have looked into regional changes. This study provides a comprehensive analysis of regional barystatic SLC trends since 1993 (the satellite altimetry era), with a focus on the uncertainty budget. We consider three types of uncertainties: intrinsic (the uncertainty from the data/model itself); temporal (related to the temporal variability in the time series); and spatial-structural (related to the location/distribution of the mass change sources). We collect a range of estimates for the individual freshwater sources, which are used to compute regional patterns (fingerprints) of barystatic SLC and analyse the different types of uncertainty. When all the contributions are combined, we find that the barystatic sea-level trends regionally ranges from −0.43 to 2.55 mm year−1 for 2003–2016, and from −0.39 to 2.00 mm year−1 for 1993–2016, depending on the choice of dataset. When all types of uncertainties from all contributions are combined, the total barystatic uncertainties regionally range from 0.62 to 1.29 mm year−1 for 2003–2016, and from 0.35 to 0.90 mm year−1 for 1993–2016, also depending on the dataset choice. We find that the temporal uncertainty dominates the budget, although the spatial-structural also has a significant contribution. On average, the intrinsic uncertainty is almost negligible. The main source of uncertainty is the temporal uncertainty from the land water storage contribution, which is responsible for at least 50 % of the total uncertainty, depending on the region of interest. The second main contributions come from the spatial-structural uncertainty from Antarctica and land water storage, which show that different locations of mass change can lead to trend deviations larger than 20 %. As the barystatic SLC contribution and its uncertainty vary significantly from region to region, better insights into regional SLC are important for local management and adaptation planning.

Питання психологічної готовності майбутнього рятувальника й досі залишається актуальним незважаючи на те, що багато науковців займалися розробкою цієї проблеми – на сьогодні виділено понад 35 різних компонентів психологічної готовності до діяльності в ризиконебезпечних умовах надзвичайної ситуації. Їх можна представити в чотирьох базових: мотиваційний, вольовий, комунікативний та моральний компонент. Рівень психологічної готовності фахівця ДСНС до екстремального виду діяльності залежить від достатньої розвиненості та вираженості базових компонентів готовності.

В межах професійної підготовки майбутніх рятувальників до екстремального виду діяльності фахівцями навчально-наукової лабораторії екстремальної та кризової психології НУЦЗУ був розроблений соціально-психологічний тренінг. Програма тренінгу складена таким чином, що активізує роботу базових компонентів психологічної готовності та надає можливість практичними навичками відпрацювати кожний з них.

Встановлено, що курсанти, які проходили соціально-психологічний тренінг при вирішенні проблемних професійних ситуативних задач значно частіше обирали: активні дії щодо порятунку себе та інших ніж курсанти, які не брали участі в тренінгу; були більш спокійними та врівноваженими; демонстрували більшу зібраність та організованість; значно краще виконували керівну функцію (надавали чіткі команди у відповідному алгоритмі); значно частіше використовують конструктивний діалог при вирішені конфліктних ситуації та демонстрували потребу у професійному самовдосконаленню. При вирішенні професійних ситуативних задач курсанти, які брали участь у тренінгу показали достовірно кращі результати у швидкості вирішення ситуативних задач та були більш впевнені у своїх діях, ніж ті курсанти, які не брали участі у тренінгу.
