The main theme of this paper is to implement the mobility model in the Cooja simulator and to investigate the impact of mobility on the performance of Routing Protocol over Low power Lossy networks (RPL) in the IoT environment. In the real world, mobility occurs frequently. Therefore in this paper, a frequently used mobility model - Random Way Point (RWP) is used for analysis. RWP can be readily applied to many existing applications. By default, the Cooja simulator does not support mobility models. For this, the Bonn Motion is introduced into Cooja as a plugin. As IoT deals with the resource-constrained environment, a comparison is done between the static environment and the mobile environment in terms of power consumption. As expected, the results indicate that mobility affects the RPL in terms of Power Consumption
The kidney contains mineral deposits in various phases of calcium salts, such as calcium oxalate and calcium phosphate. Calcium hydrogen phosphate dihydrate (CaHPO4.2H2O) / brushite is a stable form of calcium phosphate, which exists in the form of kidney and bladder stones. The study aimed to explore the possible morphological features of brushite crystals. The study was carried out on a glass slide under a microscope to observe the growth patterns of these crystals. For this purpose, a drop of gel medium (sodium meta silicate solution + 1M orthophosphoric acid solution) at pH 4.99-5.09 was placed in the middle of a glass slide and converted into a gel. A 1M calcium chloride drop was added to form the gel adequately. The glass slide was observed under a microscope till it was completely dried. Calcium hydrogen phosphate dihydrate was formed as elementary needles, needle clusters, an assemblage of needles with platy crystals, plates with spatial branches, radiating assemblage of platy crystals, star shape crystals and tetragonal bipyramidal. The Current study provides brushite crystallisation phases on glass slides for the first time. It may also be used as a model to evaluate prophylactic management against renal stones through in vitro assessment of crystal growth and aggregation inhibition and modulation of developing or developed crystals by using different natural products. However, it was a preliminary study with no quantitative or statistical analysis.
A medication error is any preventable event that may cause or lead to inappropriate use of drugs or patient harm if it is not under the control of the health care professional. Despite the fact that healthcare professionals take the responsibility very seriously, it has been estimated that 250 000 Americans die annually due to medication errors. Although, estimates show that one in ten patients worldwide is affected by medication errors while receiving hospital care, the harm can be caused by a range of incidents or adverse events. The exact incidence of medication errors in the neonatal intensive care unit (NICU) is unknown. In neonates especially premature infants, the immaturity of developing body systems affects the absorption, distribution, metabolism and excretion of drugs and therefore an exponential risk for medication errors is present. The risk of medication errors in children are much greater than adults.

The study aims to explore the possible morphological features of calcium hydrogen phosphate dihydrate (brushite) crystals on a glass slide. The study was conducted on a glass slide under a microscope to observe the growth patterns. As a result, needle, platy, star shape, and tetragonal bipyramidal crystals were observed. Different patterns of platy crystals, like plates with spatial branches and radiating assemblages of platy crystals, were also found.
Background and Objectives: Research by medical students in Yemen is limited both in terms of quantity and quality. In this light, the early recruitment of medical students into research activities can encourage them to become academically adept and professionally renowned physicians. Therefore, the aim of this study was to evaluate the knowledge, attitudes, and obstacles regarding medical research among medical undergraduates in the Faculty of Medicine and Health Sciences, Ibb University, Yemen. Materials and Methods: For the purpose of this study, a cross-sectional survey was conducted among medical students at the Faculty of Medicine and Health Sciences, Ibb University, Yemen. This survey involved medical students at their 3rd, 4th, 5th, and 6th academic years, who participated in this study from August 01, 2022, to September 30, 2022. The permission to conduct the survey was obtained from the Dean of the Faculty of Medicine and Health Sciences, Ibb University. The data gathered from the survey were analyzed using descriptive statistics. Results: About 174 (92.6%) respondents completed the survey questionnaire. The mean age of these respondents was 23.34 years. Notably, most of them demonstrated low levels of concomitant knowledge despite having positive attitudes toward medical research. Only a few students agreed with the following statements in the questionnaire: there is allotted time to pursue research (14.9% agreed); there is adequate training in research methodology (12.1% agreed); there are sufficient reward/motivations for participation in research (9.2% agreed); there is adequate training on writing a manuscript (9.2% agreed); there is adequate training on the performance of simple statistical analysis (10.4% agreed); research mentors are readily available (16.6% agreed); and it is easy to obtain a permit to conduct research from an institution (20.7% agreed). In addition, less than half of the respondents agreed with the statement that adequate medical research facilities exist in Yemen (39.1%). Conclusion: Most of the respondents in this study showed low levels of knowledge regarding research, despite having positive attitudes toward it. The primary barriers hindering research practices were the following: lack of allotted time to pursue research, lack of adequate training on writing a manuscript, and lack of training on the performance of simple statistical analysis. Moreover, the survey respondents noted a lack of research mentors and difficulties in getting approval for conducting research from their institution.
Accurate diagnosis of the cause of acute or chronic kidney dysfunction may require a percutaneous kidney biopsy (PKB). Unfortunately, the invasive nature of the procedure can lead to potential complications that may discourage the KBs. Lack of appropriate communication skills, experienced personnel and equipment, and high procedure costs can negatively impact complication rates and the frequency of conducted KBs. This nonsystematic review assesses KB procedures, indications, contraindications, complications, post-KB monitoring time, and cost. We looked for reviews and original articles published between January 2010 and Jan 2025 on Google, Google Scholar, and PubMed. Different keywords, phrases, and sentences include PKB, renal biopsy, native PKB, ultrasound guide, CT-guided, PKB, allograft PKB, and PKB procedures. KB makes histopathological and immunohistological diagnosis possible, which are necessary for diagnosis and treatment. It is often used despite the known complications. KB and other biochemical assays have tracked transplant rejection and antirejection drugs. Automatic gun spiral needles sizes 14 and 16 capture enough samples with fewer complications than gauge sizes 18 and 20. KB cost is another issue, especially in low-income areas, and deserves additional study.
In this article, we form the exact wave solutions of the Jimbo-Miwa equation and the Calogero-Bogoyavlenskii-Schiff equation by applying the new generalized (G'/G)-expansion method. We explained the new generalized (G'/G)-expansion method to look for more general traveling wave solutions of the above mentioned equations. The traveling wave solutions attained by this method are in terms of hyperbolic, trigonometric and rational functions. The graphical representation of the obtained solutions is kink soliton, singular kink soliton, singular soliton and singular periodic solution. This method is very significant for extracting exact solutions of NLEEs which habitually occur in mathematical physics, engineering sciences and applied mathematics.
For banking employees around the globe, stress on the job can be a challenge; stress can be sometimes positive and sometimes negative. Positive stress leads to productivity and negative stress leads to loss for the organization. There is already a certain level of stress in Banking employees work life and then encounter even more stress arising from the work pressure that Banking employees face on the job. Many employees cannot cope with such rapid changes taking place in the jobs. Role conflict, Service for customer, contribution, rapid technological change, lack of customer response is the great transaction of stress for the banking workers. The aim of this research is to understand roots and outcomes of job stress on the employee performance in banking sector.
The dominant sequence transduction models are based on complex recurrent or convolutional neural networks that include an encoder and a decoder. The best performing models also connect the encoder and decoder through an attention mechanism. We propose a new simple network architecture, the Transformer, based solely on attention mechanisms, dispensing with recurrence and convolutions entirely. Experiments on two machine translation tasks show these models to be superior in quality while being more parallelizable and requiring significantly less time to train. Our model achieves 28.4 BLEU on the WMT 2014 Englishto-German translation task, improving over the existing best results, including ensembles, by over 2 BLEU. On the WMT 2014 English-to-French translation task, our model establishes a new single-model state-of-the-art BLEU score of 41.0 after training for 3.5 days on eight GPUs, a small fraction of the training costs of the best models from the literature.
Marketing refers to the actions that elevate customer value by motivating them to purchase the organisation's products or services (Kusumadewi, 2019). An organisation with strong capabilities must exhibit strong marketing capacities to effectively introduce its offerings to new markets (Lee and Falahat, 2019). Marketing strategies are part of an organisation's corporate strategy, which refers to the set of choices an organisation makes to develop and capture value across its business over time. As corporate strategy essentially drives financial performance (Sull et al., 2018), effective marketing strategies must be selected to ensure the organisation's attainment of objectives and long-term success.
The study examined psychological predictors and mediators of teacher subjective well-being. Participants included 174 teachers from urban middle and highschools. The first objective was to explore the psychological correlates of the teacher SWB: self-esteem, general self-efficacy (core self-evaluation), teacher self-efficacy, optimism (cognitive trait related to the psychological well-being), and perceived social support (psychosocial trait related to the psychological wellbeing. The second objective was to investigate the mediating role of self-efficacy in the association between optimism and subjective well-being. The third objective was to explore the mediating role of teacher self-efficacy in the relation between perceived social support and teacher subjective well-being. Correlation, linear regression and mediation model analyses through the Sobel test were computed. Results confirmed the research assumptions. The findings of this study enhance the understanding of personal factors associated with teacher subjective wellbeing. The constructs linked to subjective well-being (predictors and mediators) could be target of school psychologists’ interventions, in order to have more engaged and performing teachers in schools. The findings were discussed in the context of designing the interventions for enhancement of the subjective wellbeing among teachers.
The purpose of this research was to investigate the relationship between affective tendencies in embarrassing situations and cheating behavior in a sample of adolescents. Two objectives were addressed: first, exploring the relationship between cheating behavior and shame-proneness, guilt-proneness, externalization, and detachment; second, analyzing the mediating role of detachment in the relationship between externalization and cheating behavior. The results showed positive correlations between the cheating behavior and externalization and detachment, a negative correlation with guilt, and no relation with shame. It was confirmed the mediating role of detachment. Implications for educators were discussed, emphasizing the importance of stimulation of students’ moral rules understanding.
Background: Scabies is characterized by the presence of burrows, erythematous papules, and generalized pruritus which is usually worse at night. Recently an upsurge in the incidence of scabies has been reported in many settings, including the area of the study. The study aimed to determine if there is a nexus between scabies and climate change as a risk factor. Methods: This was a case-control study carried out in a Cottage Hospital. Case files of 18, 000 patients who attended the hospital between 2016 and 2019 were reviewed. The diagnosis was mainly clinical, i.e. based on the presence of itching in the typical scabies locations, presence of scabies burrows and history of similar itching in the other members of the patient’s household. 112 cases of scabies were diagnosed within this period. Results: From 2016 to 2019, the incidence of scabies rose from 3 to 50. Prevalence among males was 59.8%, and in females 40.2%, although the difference was not significant (p=0.0.53). Compared to other age groups, prevalence was highest in the 6-17 years age group (37.5%), but the difference among the age groups was also not significant (p=0.84). Conclusions: Within four years (2016-2019), the incidence of scabies had risen from 3 to 50 in the area of the study, being higher in males (59.8%) than females (40.2%), and in children less than 18 years (37.5%). Community survey, prompt diagnosis, adequate treatment and avoidance of overcrowding might help to stem the observed rising incidence of the disease.
To the editor, On April 24, 2025, the World Health Organization (WHO) issued an urgent call to reinvigorate global action to end malaria, releasing updated guidelines that reflect both progress and persisting challenges in combating this deadly disease. [1] This renewed guidance arrives at a critical juncture: global malaria cases have plateaued, progress is faltering, and health systems in endemic regions face increasing strain from drug resistance, climate change, and funding shortfalls.
The microbiological quality of purified water is a crucial aspect in the healthcare industry to ensure safety for different applications and uses. Understanding the trend and forecasting would be of prime importance to take proactive control and protective measures before catastrophic excursions might occur leading financial and health casualties. This study analyzes microbial density, a key metric for monitoring water purification system efficacy in healthcare facilities. The objective was to transform irregular, cumulative data into a regular time series and identify the optimal ARIMA model for forecasting to support predictive maintenance and regulatory compliance. Preliminary modeling attempts were conducted using simpler approaches such as linear, exponential and Holt-Winters methods without showing promising outcomes. Descriptive statistics and distribution analysis, including the Johnson Transformation for normality, were performed. ARIMA models with differencing orders d=0, d=1, and d=2 were fitted to the Aggregated cumulative logarithmically transformed data series, with the best model at each order selected based on minimum AICc. Model adequacy was assessed through parameter significance and residual diagnostics (Ljung-Box test). Descriptive statistics showed the aggregated series non-normal (p<0 d=0) AICc=319.39) d=2) AICc=258.98)>0.5). The ARIMA(2, 1, 2) model (d=1) was optimal (AICc=256.91), with all significant parameters and white noise residuals (p>0.3), effectively addressing non-stationarity. Forecasts from ARIMA(2, 1, 2) predict stable future growth. The ARIMA(2, 1, 2) model with first-order differencing is the most appropriate and robust model for forecasting data trends. Its strong statistical fit and reliable residual properties make it a valuable tool for predictive maintenance, optimizing resources, and enhancing patient safety in healthcare water systems, provided model performance is continuously monitored. Addressing data limitations and processing requires monitoring and exploring alternative models for future improvement.

In the name of Allah, Most Gracious, Most Merciful. Blessed be He in Whose hands is Dominion; and He over all things hath Power;- He Who created Death and Life, that He may try which of you is best in deed: and He is the Exalted in Might, Oft-Forgiving;- He Who created the seven heavens one above another: No want of proportion wilt thou see in the Creation of (Allah) Most Gracious. So turn thy vision again: seest thou any flaw? Again turn thy vision a second time: (thy) vision will come back to thee dull and discomfited, in a state worn out. And we have, (from of old), adorned the lowest heaven with Lamps, and We have made such (Lamps) (as) missiles to drive away the Evil Ones, and have prepared for them the Penalty of the Blazing Fire. For those who reject their Lord (and Cherisher) is the Penalty of Hell: and evil is (such), Destination. When they are cast therein, they will hear the (terrible) drawing in of its breath even as it blazes forth, Almost bursting with fury: Every time a Group is cast therein, its Keepers will ask, “Did no Warner come to you?” They will say: “Yes indeed; a Warner did come to us, but we rejected him and said, ´Allah never sent down any (Message): ye are nothing but an egregious delusion!´” They will further say: “Had we but listened or used our intelligence, we should not (now) be among the Companions of the Blazing Fire!” They will then confess their sins: but far will be (Forgiveness) from the Companions of the Blazing Fire! As for those who fear their Lord unseen, for them is Forgiveness and a great Reward. And whether ye hide your word or publish it, He certainly has (full) knowledge, of the secrets of (all) hearts. Should He not know,- He that created? and He is the One that understands the finest mysteries (and) is well-acquainted (with them). It is He Who has made the earth manageable for you, so traverse ye through its tracts and enjoy of the Sustenance which He furnishes: but unto Him is the Resurrection. Do ye feel secure that He Who is in heaven will not cause you to be swallowed up by the earth when it shakes (as in an earthquake)? Or do ye feel secure that He Who is in Heaven will not send against you a violent tornado (with showers of stones), so that ye shall know how (terrible) was My warning? But indeed men before them rejected (My warning): then how (terrible) was My rejection (of them)? Do they not observe the birds above them, spreading their wings and folding them in? None can uphold them except (Allah) Most Gracious: Truly (Allah) Most Gracious: Truly it is He that watches over all things. Nay, who is there that can help you, (even as) an army, besides (Allah) Most Merciful? In nothing but delusion are the Unbelievers. Or who is there that can provide you with Sustenance if He were to withhold His provision? Nay, they obstinately persist in insolent impiety and flight (from the Truth). Is then one who walks headlong, with his face grovelling, better guided,- or one who walks evenly on a Straight Way? Say: “It is He Who has created you (and made you grow), and made for you the faculties of hearing, seeing, feeling and understanding: little thanks it is ye give. Say: “It is He Who has multiplied you through the earth, and to Him shall ye be gathered together.” They ask: When will this promise be (fulfilled)? – If ye are telling the truth. Say: “As to the knowledge of the time, it is with Allah alone: I am (sent) only to warn plainly in public.” At length, when they see it close at hand, grieved will be the faces of the Unbelievers, and it will be said (to them): “This is (the promise fulfilled), which ye were calling for!” Say: “See ye?- If Allah were to destroy me, and those with me, or if He bestows His Mercy on us,- yet who can deliver the Unbelievers from a grievous Penalty?” Say: “He is (Allah) Most Gracious: We have believed in Him, and on Him have we put our trust: So, soon will ye know which (of us) it is that is in manifest error.” Say: See ye?- If your stream be some morning lost (in the underground earth), who then can supply you with clear-flowing water?
Background: Hyoscine N-butylbromide (HBB; Buscopan) is commonly used in obstetric practice to accelerate labor and facilitate cervical dilation, yet variability in knowledge, attitude, and clinical usage persists among practitioners. This study assessed the knowledge, attitude, and usage patterns of HBB among medical practitioners at Abia State University Teaching Hospital (ABSUTH), Aba, Nigeria. Methods: A descriptive cross-sectional survey was conducted between August 2024 and April 2025 among 102 medical practitioners directly involved in labor care at ABSUTH. A structured, self-administered questionnaire, validated through expert review and pilot testing (Cronbach’s α = 0.78), was used to collect data on demographics, knowledge, attitude, and usage patterns. Descriptive and inferential statistics, including Chi-square tests and Pearson correlations, were performed using SPSS v. 25.0. Significance was set at p < 0.05. Results: Among 102 respondents, 93.1% had heard of HBB, and 70.6% correctly identified it as an antispasmodic. While 69.6% recognized its primary mechanism as cervical relaxation, 48% were aware of contraindications. The majority agreed that it is effective (mean = 4.12) and improves maternal outcomes (mean = 4.01). About 85.3% had administered it during labor, mostly in the active phase (64.7%), with the intravenous route being most preferred (56.9%). Statistically significant associations were observed between knowledge and attitude (χ² = 18.442, p = 0.001), specialty and frequency of use (χ² = 12.695, p = 0.048), and formal training with dosage knowledge (χ² = 15.210, p = 0.002). Knowledge, attitude, and usage scores were significantly correlated (p < 0.01). Conclusions: While the majority of practitioners at ABSUTH are familiar with and frequently use HBB in labor management, knowledge gaps and variations in practice remain. Strengthening formal training and incorporating standardized protocols could improve evidence-based usage and maternal outcomes.
