Authors: Sa’adu L. , Yusuf Y. , Abdullahi I , Muhammad S. B. , Isah A. B. 
Published: January 2023

Buck converter is a unidirectional DC-DC power converter that primarily steps down potential difference (PD) of the power bank of batteries or supercapacitors. Electric vehicles usually operate on higher voltage ranging from 45 to 72 volts. However, the electrical accessories of automobiles such as horns, trafficators, radio/players and brake or parking lights were designed to operate on 12 V DC voltage. This necessitates the use of buck converter for stepping down the voltage values to 12 volts. Nonetheless, replacing the converter when the need arises is indeed financially challenging, thus, in such a situation, the vehicles are mostly operated during the day time. Herein, we designed a buck converter using Proteus software and then constructed it with the aim of stepping down the voltage values to 12 volts at a reduced price. The design materials and the construction components used are readily available in most of the electronics shops. An outstanding performance was achieved and results indicated that the designed converter is suitable for use in electric vehicles.

Ghair Munqot art and Litrature is an unique type of literature. This literature is only linked with the languages of East i.e. Arabic, Perscian, Urdu and Punjabi languages.In this type of literature, those letter of language is used in writtings which are free from “Noqta / dot”. This field of art is known as Sanat e Mahmila or Aatila. It is not very easy so it is very important that writers and poets must have a big range of vocaboulary in concerned language and synonums are used that are free from Noqta or dots. Many writers and poets imparted to produce their contribution in this field. Likewise, most of them wrote Ghair Munqot literature on Quran’s translation, tafsir, Seerah, Naat. This research deals with the study of the those books of Seerah those were written under this art.
Parental Level of Education and its Implications of their Expectations towards their Children Academic Performance
Authors: Tantoh Mengwi Claudine 
Published: January 2023

Purpose: This study was carried out to investigate the effects of parental level of education and the type of expectations they have for their children’s academic achievement.
Methodology: This study made use of descriptive survey design. The sample was made up of 100 randomly selected lower sixth students of Government Bilingual High School (GBHS) Down Town and GBHS Ntamulung and 50 conveniently selected parents. The instruments used for data collection were questionnaire and interview guide. In data processing, a pre-designed EpiData Version 3.1 database which has in-built consistency and validation checks was used to enter the data. Further, consistency, data range and validation checks were also performed in SPSS version 21.0. The data were presented using frequency counts, graphs, percentages and the Pearson Product Moment Correlation coefficient was used to test hypotheses.
Findings: The findings indicated that there was a significant relationship between the level of education of parents and set expectations for children’s academic achievement.
Recommendations: This study recommend parents to obtain a clearer understanding of their beliefs and expectations concerning their children. For example, while many parents may be setting very high academic expectations for their children, they should understand how those expectations play out in terms of student performance. Also parents should realize that parental expectations may be unrelated to students’ prior performance, and they should be aware that parental expectations may not be linked to students' perception about their academic competence. Also, parents are discouraged from expectations based on their SES background, and encouraged to become sensitive to the children’s abilities and interests. The counselling implications for this study reveals that the guidance counsellors should be able to know when a student needs help so as to intervene with appropriate counselling programs to help the student out of a stressful situation by coming up with inclusive programs for parents, teachers and students during which educational dynamics are exposed to the stakeholders of education.

Context.—
Discrete submucosal necrotic nodules may rarely manifest as colon polyps.

Objective.—
To characterize the clinical and pathologic features of this lesion, which has been under-studied in the literature.

Design.—
We conducted an international search to compile a series. For each potential case, photomicrographs were centrally reviewed to confirm the diagnosis. We gathered clinical and pathologic information on each confirmed case.

Results.—
The final cohort included 25 patients, with 23 having 1 lesion and 2 having several (31 lesions total). Mean patient age was 62 years; 13 patients (52%) were male. Symptoms were nonspecific, although 4 patients (16%) had blood in stool; 14 patients were asymptomatic. Patient history and medications appeared noncontributory. Most cases were located in the right colon (n = 18; 58%). Mean lesion size was 0.4 cm (range, 0.1–1.7 cm). Histology typically showed a centrally necrotic nodule with peripheral fibrosis, chronic inflammation, and sometimes palisading granulomatous inflammation. Percent necrosis ranged from 5% to 95% (average, 70%), and percent fibrosis ranged from 3% to 70% (average, 25%). In 3 cases, degenerated parasitic structures consistent with Anisakis could be seen on hematoxylin-eosin and trichrome special stain. No patient experienced disease recurrence.

Conclusions.—
Submucosal necrotic nodules can present as colon polyps. Most cases are unifocal, and patients do well on follow-up. At least some examples appear to be caused by Anisakis, implicating patient diet. Patients are often asymptomatic, and many cases show no histologic evidence of the causative agent.

Published: January 2023

Teenage pregnancy is one of the most pressing issues in our society today, especially among Filipino women. The purpose of this research study is to describe the patterns and relationships between family communication and the chances of teenage pregnancy among young Filipino women. Parents play a crucial part in the growth and development of their children hence, they also influence the sexual behavior of adolescents. However, conservatism in Filipino families, rooted in religious beliefs, affects the information process of sex.
Through the case study conducted using a phenomenological approach among six teenage mothers, the researchers presented the experiences and stories of teenage pregnancy of selected teenage mothers. From this, the researchers identified the common themes among Filipino families, and their implications on teenage pregnancy. Drawing from the Family Communication Pattern Theory, this research study explores how lack of parental communication within the family affects the chances of teenage pregnancy among Filipino youth. By capturing the experiences and perspectives of teenage mothers living in Region IV-A, the researchers present an informed understanding of the previously scrutinized analyses on the causes and effects of teenage pregnancy.

Published: January 2023

This paper examines social work needs for transnational families within their local areas, based on the results of a research conducted on communities with connections to Afghanistan and Sri Lankan who live in Chiba Prefecture, Japan.
The research focused on speakers of three languages which are not covered by the multilingual services of the local governments despite their presence. The impact on their economic situations and daily lives due to Covid-19 arose from constraints and barriers in their surrounding environments from five primary factors, and the complex intertwining thereof: language; daily life customs/norms; residency status; employment, housing environment and community; and separation from family/relatives.
We conclude that it is crucial to position transnational families within community social work along with to develop multicultural and integrated communities in order to provide transnational social work services across borders in future.

Published: January 2023

Background: Harvest of hematopoietic progenitor cells via leukapheresis is being used increasingly for autologous transplantation. Adequate yield of cells per kilogram body weight of recipient is required for a successful engraftment. Collection efficiency (CE) is a useful parameter to assess quality of peripheral blood stem cell (PBSC) collection program. In this study, we report a 25-year experience in a tertiary care Hospital in Italy.
Patients and Methods: 1,026 consecutives autologous PBSC collection procedure, performed in 763 patients, from January 1996 to December 2020 were retrospectively considered. Data regarding patients, Blood Cells Separators (BCS) , apheresis procedures and PBSC products were collected in our database. In these 25 years different BCS were adopted in our Apheresis Unit (AU). In the first period (1996-1999) we used Fresenius Com. Tec, in the central period (2000-2013) we used Cobe Spectra and in the last period (2014-2020) Spectra Optia.
Results: As regards the evaluation of patients before leukapheresis, the most significant data was the increasing number of CD34+ cells. Considering the PBSC collection procedure, there was a progressive increase in the processed blood volume with a shorter apheresis duration. Data related to the PBSC collection demonstrated an increasing CD34+ cell yield and efficiency a raise in CE that was 43% using Fresenius COM-TEC BCS, 49% using Cobe Spectra BCS and 53% using Spectra Optia BCS. .
Conclusions: These results were observed considering a 25-year period, thus a great number of factors likely contributing to the observed results, including technological improvement of the instrumentation for leukapheresis, increased experience of the team operating in the Apheresis Unit, improved mobilization protocols, better criteria for patients’ selection. Focusing our attention on CE we observed quite satisfactory results with a median which rose from 43% to 53% with an increase of 10% in the observation period.

ImportanceTranscanal endoscopic ear surgery (TEES) provides minimally invasive transcanal access to the middle ear and improves middle ear visibility during cholesteatoma resection. However, the literature on outcomes following TEES alone for the removal of congenital cholesteatoma (CC) is lacking and limited to small series.ObjectiveTo assess outcomes of TEES for CC limited to the middle ear and/or mastoid antrum and to explore the risk factors associated with recidivism (ie, recurrent and/or residual cholesteatoma).Design, Setting, and ParticipantsThis cohort study evaluated retrospective, multicenter data for 271 children with CC who underwent TEES at 9 tertiary referral hospitals in South Korea between January 1, 2013, and December 31, 2021, and had a follow-up of at least 6 months after surgery.Main Outcomes and MeasuresOutcomes included the incidence of residual cholesteatoma and audiometric data after TEES. A multivariable analysis using Cox proportional hazards regression models was used to assess associations between cholesteatoma characteristics and recidivism, with hazard ratios (HRs) and 95% CIs reported.ResultsOf the 271 patients (mean [SD] age, 3.5 [2.9] years; 194 [71.6%] boys, 77 [28.4%] girls), 190 had Potsic stage I CC (70.1%), 21 (7.7%) had stage II, 57 (21.0%) had stage III, and 3 (1.1%) had stage IV. Thirty-six patients (13.3%) with residual cholesteatoma were found, including 15 (7.9%) with Potsic stage I, 3 (14.3%) with stage II, and 18 (31.6%) with stage III. In the multivariable analysis, invasion of the malleus (HR, 2.257; 95% CI, 1.074-4.743) and posterosuperior quadrant location (HR, 3.078; 95% CI, 1.540-6.151) were associated with the incidence of recidivism. Overall, hearing loss (&amp;gt;25 dB on auditory behavioral test or &amp;gt;30 dB of auditory evoked responses) decreased from 24.4% to 17.7% after TEES.Conclusions and RelevanceThis cohort study involved the largest known population to date of CC removed by TEES. The findings suggest that TEES may be feasible and effective for the removal of CC limited to the middle ear and/or mastoid antrum in children.
A field test of R package GPSeqClus: For establishing animal location clusters
Authors: Cluff H. Dean , Mech L. David 
Published: January 2023

Abstract

The ability to track animals with Global Positioning System (GPS) collars opened an enormous potential for studying animal movements and behaviour in their natural environment. One such endeavour is to identify clusters of GPS locations as a way to estimate predator kill rate. Clapp et al. (2021) developed an R package (GPSeqClus) to assess a location dataset based on user‐defined parameters to identify clusters and their characteristics. These characteristics can then help to distinguish resting‐site clusters from kill sites of their large (>50 kg) prey.

We identified location clusters of an adult male wolf Canis lupus on Ellesmere Island, Nunavut, Canada in July 2009 and tracked him until he died in April 2010. Identifying location clusters was challenging because the collar only obtained two GPS locations per day (12 h apart). In July 2010, we searched 30 of 52 location‐clusters we identified as kill/scavenge sites and found 17 of them as such, given they had muskox Ovibos moschatus or caribou Rangifer tarandus pearyi remains nearby. We also documented five wolf rendezvous sites, two den sites, and the wolf's death site to total 60 location‐clusters in all.

We used a two‐step process in testing the R Package GPSeqClus (hereafter GPSeqClus): (1) compare the number of clusters our method discerned with the number identified by the new algorithm, and (2) compare the number of biologically significant clusters (e.g. den sites, kill/feeding sites) we found with the number the new algorithm located. We made these tests with GPSeqClus by varying the search radius, number of days at a site, and minimum number of locations required for a cluster.

GPSeqClus compared well to our technique, with the best sub‐algorithm among the 25 we tested only missing three of our identified clusters and yielding six additional clusters. GPSeqClus identified 16 of the 17 confirmed sites of remains, all wolf home sites, and the wolf's carcass site. Identifying clusters using a 500‐m search radius, a 1.5‐day window, and a minimum of two GPS locations per cluster was suitable for a coarse GPS acquisition rate of two locations per day when prey are large, such as muskox or caribou.

Given that GPSeqClus performed well with our coarse location dataset, we expect it will also perform even better with a collar acquiring more than two locations per day. Having a field‐tested utility such as GPSeqClus will enhance carnivore predation studies elsewhere.

AbstractHigh Li+ conductivity, good interfacial compatibility and high mechanical strength are desirable for practical utilization of all‐solid‐state electrolytes. In this study, by introducing Li6.4La3Zr1.4Ta0.6O12 (LLZTO) with surface defects into poly(ethylene oxide) (PEO), a composite solid electrolyte (OV‐LLZTO/PEO) is prepared. The surface defects serve as anchoring points for oxygen atoms of PEO chains, forming a firmly bonded polymer‐ceramic interface. This bonding effect effectively prevents the agglomeration of LLZTO particles and crystallization of PEO domains, forming a homogeneous electrolyte membrane exhibiting high mechanical strength, reduced interfacial resistance with electrodes as well as improved Li+ conductivity. Owing to these favorable properties, OV‐LLZTO/PEO can be operated under a high current density (0.7 mA cm−2) in a Li–Li symmetric cell without short circuit. Above all, solid‐state full‐cells employing OV‐LLZTO/PEO deliver state‐of‐the‐art rate capability (8 C), power density and capacity retention. As a final proof of concept study, flexible pouch cells are assembled and tested, exhibiting high cycle stability under 5 C and excellent safety feature under abusive working conditions. Through manipulating the interfacial interactions between polymer and inorganic electrolytes, this study points out a new direction to optimizing the performance of all‐solid‐state batteries.
Orthogonal Photochemistry toward Direct Encryption of a 3D‐Printed Hydrogel

Published: January 2023

AbstractEncryption technologies are essential for information security and product anti‐counterfeiting, but they are typically restricted to planar surfaces. Encryption on complex 3D objects offers great potential to further improve security. However, it is rarely achieved owing to the lack of encoding strategies for nonplanar surfaces. Here, an approach is reported to directly encrypt on a 3D‐printed object employing orthogonal photochemistry. In this system, visible light photochemistry is used for 3D printing of a hydrogel, and ultraviolet light is subsequently employed to activate its geometrically complex surface through the dissociation of ortho‐nitrobenzyl ester units in a spatioselective manner for information coding. This approach offers a new way for more reliable encryption, and the underlying orthogonal photochemistry can be extended toward functional modification of 3D‐printed products beyond information protection.
