The library is the most important part of an institution because the library is very far from the ancient system with now, so the use of this library is very urgent in the world of education in ...general and in the world of students in particular. With a library system that is used in a professional way, superior and outstanding students will be formed. This study focuses on how the model of student empowerment in reading, library management in increasing reading interest, supporting and inhibiting factors of library management in increasing students' interest in reading at MTs Salafiyah Syafi'iyah Bandung Diwek Jombang. This research is qualitative research. While the data collection techniques using observation, interviews, and documentation. The data analysis technique uses data reduction, data display, and data verification. The model of empowering students in reading at MTs Salafiyah Syafi'iyah Diwek Jombang can be simulated with several points, namely programming for reading, motivating, and coaching the reader. In the management of the library at MTs Salafiyah Syafi'iyah Diwek Jombang there are several things that are carried out as functions of management, namely planning, organizing, implementing, and supervising. The inhibiting factor for library management in increasing students' reading interest is that it can be influenced by several factors, namely management management is still not carried out optimally, collections of books or library materials have not been maximized, human resources or librarian staff, and facilities and infrastructure.
The COVID-19 pandemic has forced the rapid adoption of remote teaching modalities including “hyflex” where students attend some class sessions in person and some online. Managing the hyflex course ...requires faculty to quickly generate several reports and to update these reports rapidly when the authorities adjust the rules, students add/drop, or the number of course sessions is changed. The creation of these reports is tedious and error-prone, so they need to be automated. However, the nature of the task precludes traditional Excel programming approaches. We use Excel’s new “dynamic array” capabilities (which are available only in Excel 365) to automate the creation and updating of the reports needed to manage the hyflex course. We show how to program the reports, and we discuss the importance of taking an iterative approach to creating effective, error-free cell formulas. To help the reader acquire genuine access to the dynamic array functions, we provide a practical tutorial on the principles and new concepts of dynamic arrays, explain how they relate to legacy array functions, and present selected dynamic array functions including SEQUENCE, FILTER, and XLOOKUP.
Microsoft Excel skills are imperative in today’s competitive market and the skill is highly demanded by businesses. The MOS Excel Expert Certification (MO-201) validates the competency that one ...should build to meet employers’ expectations. The paper addresses the statistical mean rank difference in four skill groups of the certification test. Results of the four groups of the test were compared, using the Kruskal-Wallis’s test. The null hypothesis of the equality of the means for different groups was rejected at the 5% level of significance. Because the null hypothesis was rejected, the Conover post hoc test was applied for multiple pairwise comparisons, to discern which of the sample pair combinations were significantly different. The paper examines some of the concepts of groups 2 and 3 questions where students struggled the most and rendered insights to overcome those hurdles.

Spreadsheets are widely used software tools for data entry, storage, analysis, and visualization. Focusing on the data entry and storage aspects, this article offers practical recommendations for ...organizing spreadsheet data to reduce errors and ease later analyses. The basic principles are: be consistent, write dates like YYYY-MM-DD, do not leave any cells empty, put just one thing in a cell, organize the data as a single rectangle (with subjects as rows and variables as columns, and with a single header row), create a data dictionary, do not include calculations in the raw data files, do not use font color or highlighting as data, choose good names for things, make backups, use data validation to avoid data entry errors, and save the data in plain text files.
Introduzione: La visualizzazione soggettiva delle reazioni utilizzate per l’identificazione e la quantificazione delle sostanze presenti nel calcolo urinario presentano notevoli problemi. Metodi: ...Viene descritta una nuova procedura per la determinazione del calcolo urinario. La rilevazione dei carbonati e le concentrazioni di calcio, fosforo, magnesio, ammonio, acido urico (dosaggi quantitativi su analizzatore COBAS 6000 ditta Roche) ed ossalato e cistina (determinazioni adattate su Viva E ditta Siemens) si inseriscono in un foglio Excel per ottenere i possibili principali calcoli urinari (calcio ossalato, acido urico, urato di ammonio, cistina, struvite, brushite, apatite, carbonato apatite) e più in generale “calcio fosfato”. Le determinazioni di chimica clinica sono simili a quelle utilizzate effettuate per lo studio metabolico sulle urine delle 24h in cui il dosaggio fotometrico della cistina all’acido fosfotungstico, non essendo commercializzato, è stato costruito ed adattato su analizzatore Viva E. Particolarmente utile risulta l’uso del rapido metodo quantitativo al ferro-solfosalicilico, non commercializzato e costruito nel nostro laboratorio, per la determinazione dell’ossalato nel calcolo. Risultati: Il software proposto converte le concentrazioni degli analiti in mmoli/dL e, partendo dalla struvite, definisce successivamente l’eventuale presenza di calcio ossalato, urato di ammonio ed i diversi calcio fosfato, determinati a seconda del rapporto Ca/P. La conversione finale in concentrazione delle diverse componenti presenti nel calcolo, assieme ad un eventuale residuo inorganico, da la presentazione dei dati in percentuale. Conclusioni: I dati ottenuti, specie se riferiti a concrezioni formate da più componenti, evidenziano buoni risultati se confrontati con la tecnica di riferimento FTIR suggerendo una metodica di laboratorio pratica, rapida ed affidabile. A new laboratory procedure is described for the determination of urinary calculus. The detection of carbonates (production of carbon dioxide with the use of concentrated sulfuric acid) and the concentrations of calcium, phosphorus, magnesium, ammonium, uric acid (quantitative dosages carried out on COBAS 6000 analyzer of the Roche company) and oxalate and cystine (determinations adapted by us on the Siemens Viva E instrument) they are inserted in an Excel sheet created by us in order to obtain the main possible urinary calculations (calcium oxalate, uric acid, ammonium urate, cystine, struvite, brushite, apatite, carbonate apatite and more generally "calcium phosphate." The clinical chemistry determinations are similar to those used for the metabolic study carried out on the urine of 24 hours in which the photometric dosage of cystine with phosphotungstic acid, not being marketed, was built by us and adapted on Viva E analyzer. The use of the rapid quantitative method, with non-commercial sulfosalicylic acid, is particularly useful zato and then built in our laboratory, for the determination of oxalate in the calculation. The software proposed by us converts all the concentrations of the above mentioned analytes to mmoles / dL and, starting from struvite (molecular ratios: 1P - 1Mg - 1NH4), the possible presence of calcium oxalate is subsequently defined (molecular ratios: 1Ca - 1Ox ), that of ammonium urate and the different calcium phosphate (brushite, apatite / carbonate apatite and "calcium phosphate"), the latter determined according to the Ca / P ratio (brushite: <1.155; 1.155≥ "calcium phosphate" <1 , 45; apatite ≥1.45). The final conversion into concentration of the various components present in the calculation, together with any inorganic residue, determines the presentation of the data as a percentage. The data obtained, especially if referring to concretions formed by several components, show good results when compared with the FTIR reference technique.
•The connection capabilities of Aspen Hysys are analyzed, and four automation approaches proposed for testing.•The performance of these strategies is tested with the tools Microsoft Excel, Matlab, ...Python and Unity.•Experiments show spreadsheet connection to be the only approach reliably functional in the four programs.•The code is made available for use.
Researchers often find the need to integrate commercial process simulators such as Aspen Hysys, Aspen Plus, PRO/II or others with their own applications. However, despite the relevance of these tools, the authors have found no systematic research on connection methodologies, a gap in literature that they aim to address with this work. The authors will study the connection methodologies of the popular process simulator Aspen Hysys with four tools that hold current or potential use for chemical engineering researchers: Microsoft Excel (VBA), Matlab, Python and Unity (C#). Four different communication approaches are presented (direct communication, indirect communication, internal spreadsheets, and data tables), with results being compared in terms of accuracy of communication, time of exchange, and deviation in the results. The code used in the experiments is made available to the readers.
Although the popularity of the Bayesian approach to statistics has been growing for years, many still think of it as somewhat esoteric, not focused on practical issues, or generally too difficult to ...understand.Bayesian Analysis Made Simple is aimed at those who wish to apply Bayesian methods but either are not experts or do not have the time to cre
