Preliminary frameworks and models for telework maturity within organisations
This paper is a preliminary step to assess the feasibility of telework for any given organisation. We posit two qualitative frames of telework to define the additional, digital referential platforms that exist with regard to work today: abstraction and conceptualisation. To communicate research within this field we utilise a language taxonomy derived out of a review of the relevant literature. Furthermore, we
propose a transformer model to serve as a means to i) interpret quantitative aspects of telework such as metrics and KPIs and ii) inform stakeholder decisions with regard to appropriate telework configurations for their respective company

Dvali-Gabadadze-Porrati Cosmology in Bianchi I brane
The dynamics of Dvali-Gabadadze-Porrati Cosmology (DGP) braneworld with an
anisotropic brane is studied. The Friedmann equations and their solutions are
obtained for two branches of anisotropic DGP model. The late time behavior in
DGP cosmology is examined in the presence of anisotropy which shows that
universe enters a self-accelerating phase much later compared to the isotropic
case. The acceleration conditions and slow-roll conditions for inflation are
obtained
Farmakokinetika ceftazidima u bivolske teladi s vruÄicom uzrokovanom lipopolisaharidom bakterije E. coli.
The pharmacokinetic properties of ceftazidime, a third generation cephalosporin, were investigated in experimentally induced febrile buffalo calves (n=5) after a single intravenous administration at a dose rate of 10 mg/kg body weight. The fever was induced by a single/repeated intravenous injection of E. coli lipopolysaccaride (1 ÎŒg/kg). Ceftazidime concentrations in the plasma and urine were determined by microbiological assay. Ceftazidime disposition was best fitted by a bi-compartmental open model with first-order elimination. At 2.5 min, the concentration of ceftazidime in the plasma of the febrile animals was 152.3 ± 6.77 ÎŒg/mL and the drug was detected up to 14 h. The elimination half-life and volume of distribution were 3.73 ± 0.42 h and 0.26 ± 0.05 L/kg, respectively. The distribution half-life, AUC and total body clearance (ClB) were 0.24 ± 0.03 h, 217.3 ± 23.4 ÎŒg/mL.h and 47.9 ± 4.57 mL/kg/h, respectively. Urinary excretion of ceftazidime was less than 28 percent after 32 h of administration of the drug in the febrile animals. An efficacy predictor, measured as the time over which the active drug exceeds the bacteria minimum inhibitory concentration (T>MIC), was calculated. T>MIC was 73% of the recommended dosing interval (8h) for bacteria with a MIC90â€4 ÎŒg/mL.FarmakokinetiÄka svojstva ceftazidima, cefalosporinskog antibiotika treÄe generacije, istraĆŸena su u febrilne bivolske teladi (n=5) nakon njegove jednokratne intravenske primjene u dozi od 10 mg/kg tjelesne mase. VruÄica je u teladi bila pokusno izazvana jednokratnim odnosno ponovljenim intravenskim davanjem
lipopolisaharida bakterije E. coli u dozi od 1 mg/kg. Koncentracija ceftazidima u plazmi i mokraÄi odreÄena je mikrobioloĆĄkim postupkom. FarmakokinetiÄko ponaĆĄanje ceftazidima u febrilnih ĆŸivotija opisano je u dva modela. Za 2,5 minuta koncentracija ceftazidima u plazmi febrilnih ĆŸivotinja iznosila je 152,3 ± 6,77 ÎŒg/mL, a lijek se mogao dokazati sve do 14 sati nakon primjene. Poluvrijeme njegova izluÄivanja iznosilo je 3,73 ± 0,42 h, a koliÄina raspodjele 0,26 ± 0,05 L/kg. Poluvrijeme njegove raspodjele bilo je 0,24 ± 0,03 h, povrĆĄine ispod koncentracijske krivulje u plazmi 217,3 ± 23,4 ÎŒg/mL.h, a ukupni klirens iz organizma 47,9 ± 4,57 mL/kg/h. IzluÄivanje ceftazidima mokraÄom bilo je manje od 28% nakon 32 sata od primjene. PredviÄena uÄinkovitost lijeka, izmjerena kao vrijeme u kojem je aktivna supstancija bila iznad minimalne inhibicijske koncentracije (T>MIC), bila je 73% od preporuÄenog razmaka primjene (8h) za bakterije s MIC90â€4 ÎŒg/mL
Performance Comparison of New Heuristic With Genetic Algorithm in Parallel Flow Line Set Up
A new heuristic has been developed to solve the problem in parallel flow line scheduling. It involves the minimization of the makespan by the optimal allocation of a finite number of jobs to finite number of lines in the first phase and the optimal sequencing of allocated jobs in each line in the second phase. Here new heuristic and genetic algorithm for analyzing the parallel flow line scheduling are discussed and executed on a set of randomly generated problems. The results obtained for the test problems suggest that the developed new heuristic can be used successfully to solve large scale parallel flow line scheduling problems
Continuous user authentication featuring keystroke dynamics based on robust recurrent confidence model and ensemble learning approach
User authentication is considered to be an important aspect of any cybersecurity program. However, one-time validation of userâs identity is not strong to provide resilient security throughout the user session. In this aspect, continuous monitoring of session is necessary to ensure that only legitimate user is accessing the system resources for entire session. In this paper, a true continuous user authentication system featuring keystroke dynamics behavioural biometric modality has been proposed and implemented. A novel method of authenticating the user on each action has been presented which decides the legitimacy of current user based on the confidence in the genuineness of each action. The 2-phase methodology, consisting of ensemble learning and robust recurrent confidence model(R-RCM), has been designed which employs a novel perception of two thresholds i.e., alert and final threshold. Proposed methodology classifies each action based on the probability score of ensemble classifier which is afterwards used along with hyperparameters of R-RCM to compute the current confidence in the genuineness of user. System decides if user can continue using the system or not based on new confidence value and final threshold. However, it tends to lock out imposter user more quickly if it reaches the alert threshold. Moreover, system has been validated with two different experimental settings and results are reported in terms of mean average number of genuine actions (ANGA) and average number of imposter actions(ANIA), whereby achieving the lowest mean ANIA with experimental setting II
Water-pipe smoking and albuminuria: new dog with old tricks
Water-pipe (WP) smoking is on rise worldwide for the past few years, particularly among younger individuals. Growing evidence indicates that WP smoking is as harmful as cigarette smoking. To date, most of the research has focused on acute health effects of WP smoking, and evidence remains limited when it comes to chronic health effects in relation to long-term WP smoking. Therefore, the aim of this study was to examine the association between WP smoking and albuminuria in apparently healthy individuals. This analysis was conducted on data of a population-based cross-sectional studyâthe Urban Rural Chronic Diseases Study (URCDS). The study sample was recruited from three sites in Pakistan. Trained nurses carried out individual interviews and obtained the information on demographics, lifestyle factors, and past and current medical history. Measurements of complete blood count, lipid profile, fasting glucose level, and 24-hour albuminuria were also made by using blood and urine samples. Albumin excretion was classified into three categories using standard cut-offs: normal excretion, high-normal excretion and microalbuminuria. Multiple logistic regression models were used to examine the relationship between WP smoking and albuminuria. The final analysis included data from 1,626 health individuals, of which 829 (51.0%) were males and 797 (49.0%) females. Of 1,626 individuals, 267 (16.4%) were current WP smokers and 1,359 (83.6%) were non-WP smokers. WP smoking was significantly associated with high-normal albuminuria (OR = 2.33, 95% CI 1.68-3.22, p-value <0.001) and microalbuminuria (OR = 1.75, 95% CI 1.18-2.58, p-value 0.005) after adjustment for age, sex, BMI, social class, hypertension, and diabetes mellitus. WP smoking was significantly associated with high-normal albuminuria and microalbuminuria when analysis was stratified on hypertension and diabetes mellitus categories. WP smoking has a strong association with albuminuria in apparently healthy individuals. More research is warranted to evaluate the temporality of this association between WP smoking and albuminuria
Pengujian Kinerja Couple Thermoelektrik sebagai Pendingin Prosesor
Thermoelektrik merupakan piranti elektronik yang bekerja berdasarkan Seebeck Effect yakni apabila ada arus searah/ Dirrect Current yang mengalir pada thermoelektrik maka menimbulkan perbedaan suhu pada kedua keping semikonduktornya. Thermoelektrik juga berlaku sebagai generator ketika terjadi perbedaan suhu pada kedua sisi semikonduktornya maka menghasilkan arus searah / Dirrect Current. Kedua prinsip kerja ini apabila diterapkan pada prosesor pada suhu tinggi maka panas dari prosesor akan diserap oleh thermoelektrik pertama yang menghasilkan tegangan dan arus untuk disalurkan thermoelektrik yang kedua sehingga memberikan Cooling Effect pada prosessor. Percobaan ini menggunakan 2 thermoelektrik, satu sebagai sumber arus dan satunya lagi sebagai pendingin dengan variasi perbedaan suhu dan tegangan pada pemanas/heater sebagai sumber panas. Variasi perbedaan suhu dilakukan dengan nilai antara 21-50 oC, sementara untuk variasi tegangan dengan nilai 1,5 V, 3V, 7,5V, 9V, dan 12V. Hasil percobaan menyakatakan bahwa dengan perbedaan suhu 45-50 oC menghasilkan tegangan 3,27 Volt untuk dialirkan pada thermoelektrik kedua dengan nilai suhu minimum 24,25 oC, sehingga suhu prosesor akan turun sebesar menurun 24,88 oC menjadi 49,13 oC. Dengan demikian maka efektivitas maksimum dari pendingin prosesor couple thermoelektrik ini adalah 64,68%
