Development of Cost Efficient Solar Powered System for Rural Areas
Authors: Ahmad Habibu , Abdulsalam Mahmud 
Published: August 2023

We proposed a cost efficient, environmentally friendly commercial solar powered phone charging station for application in rural areas. Sun energy is tapped using photovoltaic solar panel (PV), the system converts the tapped energy into electricity, charge controller regulates the generated energy, part of the generated electricity is used during the day and part stored in a battery to be used at period where there is less shun shine or absent. Cost analysis of the developed system suggested its almost free and noiseless when compared with the conventional generator powered system.
Histoplasmosis: Laboratory Diagnosis
Authors: Dumea Elena , Dantes Elena 
Published: August 2023

The diagnosis of histoplasmosis is based on clinical, imaging, and laboratory evidence of the disease. The gold standards of laboratory diagnosis are the presence of the fungus in the pathological examination of tissues and its isolation (direct microscopy, histopathology, cytopathology) in mycological culture (4–6 weeks required) by clinical specimens. The antibody test, sometimes negative in immunocompromised patients, must be performed at least four weeks after acute infection to be positive. The antibody test is most useful in subacute and chronic forms of histoplasmosis. The antigen test is the most common method for establishing the diagnosis of acute pulmonary histoplasmosis or progressive disseminated histoplasmosis. The antigen test in urine or serum has good sensitivity, better in bronchoalveolar lavage fluid. There are skin sensitivity tests with low sensitivity that are used only for epidemiologic studies and are not recommended for diagnosis. Molecular diagnosis has improved the sensitivity of clinical specimens. Laboratory PCR assays with different molecular targets have been developed. Currently, the main procedure for molecular diagnosis of histoplasmosis is the application of a rapid DNA probe on a fungus isolated from a culture. This chapter summarizes the currently available tools for the laboratory diagnosis of histoplasmosis, focusing on the complexity of the assays and their performance in different clinical contexts.
Examining the Critical Need for Tailored Adolescent Opioid Education: A National Study
Authors: Abraham Olufunmilola , Szela Lisa , Rosenberger Claire , Birstler Jen , Li Jenny , Hetzel Scott 
Published: August 2023

OBJECTIVE
Prescription opioid education can be a preventative measure for opioid misuse. However, most research focuses on adult perspectives rather than adolescents. This study aimed to understand adolescents’ attitudes, perceptions, knowledge about prescription opioids, and preferences and prior educational exposure to opioid safety.

METHODS
Data were collected from November to December 2020. Quota sampling through Qualtrics was used to recruit a national sample of 13- to 18-year-old adolescents who lived in the United States and could understand English.

RESULTS
A total of 774 responses were analyzed. The most frequently reported source of opioid information was speaking with parents (72%). More than half (54.7%) of participants preferred technology-based education. Participants with a personal history of opioid prescription scored no differently on safe handling and storage of opioids. There was a strong relationship between participants who reported prior knowledge of what opioids are and stopping their friend from using an opioid medication for non-medical purposes (χ2 (1, N = 684) = 3.5; p = 0.042). Participants with prior education on opioid disposal did not know that ­returning opioids to the pharmacy was correct (χ2 (1, N = 425) = 3.8; p = 0.254).

CONCLUSIONS
Participants were less knowledgeable about safe storage and disposal of opioids, preferred technology-based education, and were extremely likely to talk to their parents about opioid information. Findings reaffirm the significance of opioid safety education and communication between adolescents and parents. Adolescent demographic characteristics, preferences, and prior knowledge should be considered when providing opioid safety education.
High-Cost Drug Policies in Canadian Children’s Hospitals: An Exploratory Study
Authors: Pucchio Aidan , Rieder Michael 
Published: August 2023

OBJECTIVE
Over the past decade a number of effective but costly drugs have entered the therapeutic arena. Ethical and logistical challenges associated with including children in research and policy have produced variability in public policy on funding pediatric drugs, with inconsistent coverage across Canada. The purpose of this study was to explore the processes for funding high-cost pediatric drugs in Canadian children’s hospitals.

METHODS
We conducted a cross-sectional, text-based survey of all 19 chairs of Canadian departments of pediatrics about the funding and accessibility of high-cost drugs. Thematic qualitative analysis was performed to organize, sort, and code verbatim written responses and follow-up correspondence.

RESULTS
Responses were received from all 19 Canadian departments of pediatrics surveyed (100% response rate). Three major themes emerged about pediatric high-cost drug policies: inconsistency between funding processes, variability in funding sources, and frustration with the current system. In aggregate, a clear concern emerged that current funding options were heterogenous and inadequate to meet patient needs.

CONCLUSIONS
There was widespread consensus from respondents that current options for funding pediatric high-cost drugs were inadequate and that there was need for urgent action to address this problem. Policy changes are needed to sustain and improve access to high-cost drugs for Canadian children. We propose 3 solutions, including the creation of a national framework for funding high-cost pediatric drugs, increased incorporation of pediatric considerations in drug research and development, and a multidisciplinary drug summit on pediatric therapeutics.

Authors: Lingle Abby , Baker Bethany , Williams Kristi , Lee Brian , Wright S. Margaret , Yoder Alannah 
Published: August 2023

OBJECTIVE
The purpose of this study is to evaluate the effects of pharmacy integration into care transitions for children with medical complexity. These children are at a higher risk for medication errors and adverse effects because of their complex medication regimens. In addition, care transitions increase the risk for medication errors, especially during hospital-to-home transitions.

METHODS
This was a retrospective chart review of patients enrolled in a complex care clinic who were discharged between September 1, 2021, and December 31, 2021, and who had received a discharge medication evaluation. Intervention categories were predetermined (medication reconciliation and clinical interventions) and documented. The primary outcome was to quantify and characterize the types of interventions made by the pharmacist. Descriptive statistics were used for data analysis. Continuous data were analyzed using Wilcoxon rank sum test, and correlation was measured using Spearman correlation values.

RESULTS
A total of 92 clinic encounters for 60 patients were included, with a median patient age of 7 years (IQR, 5–12.3), median length of stay of 3.2 days (IQR, 1.2–5.7), and a median number of 18 discharge medications (IQR, 14.8–25). A total of 283 interventions were made, consisting of 192 (68%) clinical interventions and 91 (32%) medication reconciliation interventions. In addition, 82 (89%) of the clinic encounters had at least one pharmacist intervention.

CONCLUSIONS
Pharmacist evaluation of a patient’s discharge medication regimen clarifies and better optimizes the patient’s medication regimen.

Dynamics of flocking models with two species
Authors: Zhao Qingjian , Shi Shaoyun , Li Wenlei 
Published: August 2023

This article studies the flocking behavior of self-organized agents in two species. First, referring to the work of Olfati-Saber and the classical Cucker-Smale model, we establish a discrete system describing the flocking dynamic of the agents in two species. Second, by using the LaSalle's invariance principle, we show that the system with global interaction will achieve unconditional time-asymptotic flocking, and thesystem with local interaction has a time-asymptotic flocking under certain assumptions.Moreover, we investigate the local asymptotic stability of a class of flocking solutions. Finally, some numerical simulations and qualitative results are presented.

Published: August 2023

In this article we consider the class \(\mathrm{CSL}_7^{4s\infty}\) of non-degenerate real planar cubic vector fields possessing four distinctreal infinite singularities and invariant straight lines, including the line at infinity of total multiplicity 7. We prove that there are exactly 93 distinct configurations of invariant straight lines for this class, and present corresponding examples for the realization of each one of the detected configurations.

Bresse systems with localized Kelvin-Voigt dissipation
Authors: Aguilera Contreras Gabriel , Munoz-Rivera Jaime E. 
Published: August 2023

We study the effect of localized viscoelastic dissipation for curved beams. We consider a circular beam with three components, two of them viscous with constitutive laws of Kelvin-Voigt type, one continuous and the other discontinuous. The third component is elastic without any dissipative mechanism. Our main result is that the rate of decay depends on the position of each component. More precisely, we prove that the model is exponentially stable if and only if the viscous component with discontinuous constitutive law is not in the center of the beam. We prove that when there is no exponential stability, the solution decays polynomially.

Monotone solutions of first order nonlinear differential systems
Authors: Wang Lianwen , Mubarak Abdulrahman 
Published: August 2023

This article concerns the classification, continuablity, boundedness, and existence of solutions for a system of first order nonlinear differential equations. First, we prove that all solutions of the system are eventually monotonic and can be separated into two classes. Then we discuss the continuability of solutions. After that we establish necessary and sufficient conditions for the boundedness of all solutions. Also, we study the existence of monotone solutions in certain classes.

“The floods of the Neva, XVIII century”. Database
Authors: Malova T. I. 
Published: August 2023

The problem of systematizing information about the historical floods of the Neva seems to be extremely urgent today. The construction of predictive models, the feasibility of building new hydraulic structures, planning of engineering, economic, environmental, social and cultural activities are impossible without a comprehensive analysis of information about floods. The official catalogs available to researchers, unfortunately, are not informative enough and are full of distortions. Working with a large array of numerical values characterizing the flood heights of the Neva of different eras, the inconsistency of these values, even within the framework of individual events, the importance of clarifying them in order to preserve all information aspects — all this led to the need to form the Database of floods. The main task of its creation is information support of research related to the restoration of distorted rows (or individual historical floods of the Neva).
Recent Climatic Change Research in the Chukchi and Beaufort Seas Based on Numerical Simulation
Authors: Iakshina D. F. , Golubeva E. N. 
Published: August 2023

This study analyses climatic changes in the Chukchi Sea and the Beaufort Sea based on numerical modeling using a regional ice-ocean model. Numerical experiments were carried out for the period 2000–2019. NCEP/NCAR reanalysis data were used to determine the ocean and sea ice surface fluxes. The temperature, salinity, and transport of Pacific waters entering the Arctic Ocean were specified as boundary conditions in the Bering Strait. Three types of boundary values were used for the experiments: a) monthly average climate data averaged over the period 1990–2003; b) monthly average climate data averaged over the period 2003–2015; c) average monthly measurement data since 2016 to 2019. The sensitivity of the model to the variability of the transport and temperature of the incoming Pacific waters was studied, and the effect on the ocean heat content, the volume and sea ice extent was analyzed.Numerical experiments simulate the transport of warm Pacific water across the Chukchi shelf in the north direction and onto the Beaufort Sea shelf, the process of warm water sinking on the continental slope in the autumn-winter period. In recent years, at the points on the boundary of the shelf and deep-water areas, the amplitude of seasonal temperature fluctuations in the surfacelayer increases and the temperature rises significantly at a depth of 100 m.The simulation results demonstrate an increase in the ocean heat content and decrease in the ice volume in the Beaufort and Chukchi Seas, caused by an increase in atmospheric temperature. We also showed that the increase in temperature and transport of the Pacific water, which began after 2003, contributed to an additional increase in the ocean heat content of both seas, a reduction in the ice cover area, and a delay in the ice formation in the Chukchi Sea.
