Authors: Udoekanem Namnso Bassey , Nagya Umar
Published: September 2022

Land is a major factor of production and a vital asset in the socio-economic development of any country or society. Due to the continuous increase in urban population, resulting in rapid urbanisation,  access to urban land has become a challenge in Minna. This paper examines the factors that influence access to urban land for private housing development in the city. The study adopted descriptive and causal research designs. Data for the study were obtained from field survey through structured questionnaire administered to private housing developers in the study area using simple random sampling technique. Descriptive and inferential statistical techniques were used to analyse the data. The study found that titling and locational factors, socio-economic factors, procedural bottlenecks, land condition and accessibility are the significant factors that drive access to land for private housing development in the city. It recommends that stakeholders in land administration and management in the city should consider these factors in the land administration system to facilitate private developers’ access to land for private housing development in the city.

This study aimed to compare the applicability of three methods of filling gaps in rainfall and temperature data from thirteen automatic weather stations (AWS) in the state of Pernambuco, from January to December 2019. The methods used were arithmetic mean, regional weighting, and simple linear regression. The data estimated by filling techniques have been subjected to comparison using R² and descriptive statistical analysis. The estimated data of air temperature presented R2 equal or very close to 1 for the three methods. On the other hand, the estimated data of rainfall showed values similar or closer to the real data only to regional weighting (R² = 1) and linear regression (R² = 0.99) methods. The smallest values ​​of standard deviation (1.70) for temperature were obtained with linear regression. The regional weighting method and unfilled data showed greater uniformity for precipitation. The analyzed methods to estimate the climatic variables, air temperature, and precipitation, on a monthly scale, were efficient to fill in missing data in the evaluated AWS. The simple linear regression method is more efficient and adequate, followed by regional weighting, to fill in missing data in climate databases.

Published: September 2022

This research study aims to develop a new blend of clay bricks using varying percentages of recycled glass fines and recycled plastics in masonry bricks at low curing temperatures. Alkaline-activated solutions used in this research study were sodium hydroxide and sodium silicate. Having tried various percentages of alkaline activators, the suitable amount of alkaline activator was set at 20%. Brick samples were placed in an oven at a heating temperature of 50°C for 24 h (to reduce the moisture content), followed by a temperature of 155°C for 48 h. Earlier findings demonstrated that the moisture curing for the sample was 50°C for 48 h, and the heating temperature increased to 155°C for 24 h. A series of laboratory tests on the brick samples such as compressive strength, water absorption, linear shrinkage and scanning electron microscopy characterisation were carried out in this study. The examined curing conditions were 7 and 28 days. The results from the experiment revealed that the relationship between water absorption and curing conditions satisfied the minimum requirement of masonry bricks using recycled glass fines and plastics.

On the problem of reduction in the dynamics of a gyrostat
Authors: Makeev Nikolay
Published: September 2022

We consider the motion relative to the fixed pole of the gyrostat, which occurs in the automatic control mode according to R. Grammel. The gyrostat is acted upon by a system of specified non-stationary forces caused by the influence of the external environment. A description is given to the procedure for reducing the dynamic system of the gyrostat, for which there must be a first integral linear in the components of the angular sorption of its carrier. The reduction is realized as a result of constructing a nonlinear integro-differential equation that determines the dependence of one of the components of the absolute angular velocity vector of the gyrostat carrier. Some special cases of reduction associated with the structural and dynamic features of the gyrostat and the types of a given analytical dependence of the components of the gyrostat moment vector are considered.

Purpose: This study aimed to determine the prevalence and length of the anterior loop (AL) of the inferior alveolar nerve, and evaluate the emergence direction of the mental nerve and the location of mental foramen in a group of Iranian patients. Material and Methods: This study was carried out on CBCT scans of 150 patients (57 males and 93 females; mean age 40.8 ±14.33 years). The presence and extent of the AL was determined in reconstructed images. The emergence path of the mental nerve was classified into three groups: anteriorly directed emergence, right-angled pattern of emergence, and posteriorly directed emergence. The location of mental foramen relative to adjacent premolars was determined. Results: AL was identified in 14.7% of the cases with a mean length of 1.39± 0.91 mm (range 0.25 to 3.50 mm). No significant differences were observed in the prevalence and extent of the AL between genders (p>0.05). The right-angled pattern of emergence was more dominant (43.7%). The most prevalent location of mental foramen was between the first and second premolars (68.3%). There was no significant association between the presence of AL with the path of emergence of the mental nerve (p=0.627) or the location of the mental foramen (p=0.100). Conclusion: The prevalence of anterior loop was relatively low in the present sample (14.7%) with a length range of 0.25 to 3.5 mm. Due to the importance of this anatomic variation in implant surgery, it is suggested to carefully assess CBCT images before the surgical procedure to avoid neurosensory complications.

Aim: To determine the type and frequency of sequelae in permanent teeth as a result of traumatic dental injuries in primary teeth in pediatric patients attended to at the Hospital Base Valdivia, between 2007 and 2012. Material and Methods: A descriptive study was conducted. The medical records of pediatric patients who were affected by traumatic dental injuries in primary teeth and went to the Sub-department of Dentistry of the Hospital Base Valdivia, Chile, were selected according to inclusion and exclusion criteria. The recorded data was: age of the child at the time of the accident, gender, affected primary tooth, type of traumatic dental injuries, and diagnosis of the permanent successor tooth. Descriptive statistics were performed. A chi-square test was used to establish differences between type of traumatic dental injuries and condition of the permanent tooth. Results: The most frequent diagnosis of traumatic dental injuries in primary dentition was subluxation. The primary tooth with the highest frequency of traumatic dental injuries was the right maxillary central incisor; 58.2% of the permanent successors presented some developmental disturbances. The most frequent sequelae observed in permanent teeth were chronological alterations of the eruption. Conclusion: There is a high frequency of sequelae in permanent dentition as a result of trauma in primary dentition. The most frequent sequel observed was chronological alteration of the eruption. It is fundamental to inform parents about the possible consequences that could arise and emphasize the importance of attending periodic follow up in order to prevent or minimize possible sequelae in permanent teeth.

Introduction: The aim of this study was to assess the agreement between oral and maxillofacial radiologists (OMFR) and oral and maxillofacial surgeons (OMFS) for the detection of bifid mandibular canal (BMC) and accessory mental foramen (AMF) using cone-beam computed tomography (CBCT). Material and Methods: This retrospective study involved 22 examiners (11 OMFR and 11 OMFS) who independently assessed 30 CBCT volumes from patients (n = 60 hemi-mandibles) under preoperative radiographic evaluation for implant placement. The examiners scored the presence of BMC and AMF in each hemimandible. The interexaminer agreements were assessed using Fleiss' kappa statistics. Results: For intra-examiner agreement, 40% of the sample was reevaluated. The interexaminer agreement between OMFR and OMFS was slight (0.12) for the detection of BMC and fair (0.24) for AMF. The agreement among OMFR for detection of BMC was fair (0.22), and it was slight among OMFS (0.15). The agreement among OMFR for detection of AMF was substantial (0.61), and among OMFS it was fair (0.22). Agreements between OMFR and OMFS were slight for BMC and fair for AMF, independently of the years of experience. Intraexaminer agreement ranged from 60% to 90% among OMFR and from 55% to 90% among OMFS. Conclusion: A slight and a fair agreement between OMFR and OMFS was found for the detection of BMC and AMF, respectively. In general, OMFR obtained higher agreement among themselves, mainly for detection of AMF.

The Concept of Relationship Between Debt and Receivable: Evidence on Basic Industrial Companies in Indonesia
Authors: Darmawan Darmawan , Jufri Achmad
Published: September 2022

The study's purpose was to determine whether there is a two-way influence between debt and receivables, the response of a variable to sShocks that occur in other variables and the contribution of each variable to other variables. Debt and receivable data are taken from 48 of the 91 companies in the basic industrial sector listed on the IDX. The statistical model used in this study is the Vector Autoregression Model, which aims to test the direction of influence between two variables. The results show that debt affects receivables, while accounts receivable do not affect debt. So there is only a one-way relationship between debt to receivables. This finding reinforced that the debt response to the shock in receivables did not find a significant response. Meanwhile, the response of receivables variable shock to itself since period 1 has fluctuated and has been stable since period 6. The receivables response to the shock in debt began to respond in the second period and was stable from period 6. The contribution of the receivable variable to itself had a negative trend. In contrast, the contribution of the variable debt to receivables shows a positive direction.

Authors: Trang Le Thi Huyen , Kolleck Nina
Published: September 2022

Volunteering plays a central role in cultural and arts education in rural areas in Germany. However, a decrease in the number of volunteers in structurally weak regions can be observed in recent years. This poses existential challenges for cultural and arts education. The promotion of social networks and regional cooperation, as well as a sense of place, can counteract this decline. This article aims to explore how sense of place influence cooperation and thus social networks between actors of different institutions in the context of cultural and arts education in rural areas. A total of 34 interviews and egocentric network maps were conducted with different local actors (e.g., volunteers in the theatre association, mayors, etc.) in four municipalities. The data were analysed using qualitative content analysis. Our results show that, through active participation in cultural events and associations, new cooperation is created and maintained, which also expands the social network. This active participation can be positively influenced by the existing attachment to the region and cultural places.

Purpose: This present study aimed to share experiences in the diagnosis and management of brain death (BD) and cadaveric donation cases, detected in a research hospital during the COVID-19 pandemic.

Materials and Methods: BD cases diagnosed between 15/03/2020-15/05/2021 in our intensive care units (ICU) were retrospectively evaluated. Patients’ demographic characteristics, primary diagnoses, ICU admission time, and length of hospital stay were analyzed. Clinical suspicion, diagnosis, declaration, and donation or cardiac arrest times and supplementary tests to support the clinical judgment performed were also evaluated.

Results: 37 cases, were included in the study. Intracranial hemorrhage was the most common (54.1%) diagnosis in ICU admissions. Apnea tests could be performed only in 27 patients (73%). Cerebral CT-angiography was used as a supplementarytary test in 27 (73%) cases. Family consent for organ donation was obtained from 10 patients (27%), and 70% (n= 7) of them became donors. The time between ICU admission and BD diagnosis time was 114±92.8 (11-360) hours, the time between clinical suspicion and diagnosis was 32±15.1 (4-78) hours, the time between diagnosis and cardiac arrest of non-donors was 24±15.2 (5-72) hours, and the time between diagnosis and donation was 23±7.6 (15-35) hours.

Conclusion: Occupancy in ICUs due to COVID-19 has reduced the admission of patients who may be donors to ICUs, and there has been a decrease in the number of BD detection, family approval, and organ donation in our hospital.

Published: September 2022

Purpose: There are few studies comparing the effectiveness of anti-osteoporotic drugs among elderly population. In this study, we aimed to compare the effectiveness of alendronate, zoledronic acid, and denosumab in older adults.

Materials and Methods: A total of 350 older adults with osteoporosis, aged 65 and over were included in this retrospective study. The number of patients receiving alendronate, zoledronic acid, and denosumab was 111, 121, and 118, respectively. Bone mineral density (BMD) was measured at baseline and 24th month by performing dual-energy x-ray absorptiometry (DXA) scans.

Results: The age, comorbidities, and laboratory analysis results of the patients were similar. While there was no statistically significant difference in BMD response at the femoral neck between the treatment groups (Baseline BMDs for alendronate, zoledronic acid, and denosumab were 0.61, 0.59, and 0.58, respectively, while 24th month BMDs were 0.62, 0.60, and 0.59, respectively), alendronate and zoledronic acid improved lumbar spine BMD more than denosumab (Baseline BMDs for alendronate, zoledronic acid, and denosumab were 0.74, 0.74, and 0.71, respectively, while 24th month BMDs were 0.77, 0.78, and 0.73).

Conclusion: This study has shown that, like parenteral antiresorptive agents, alendronate can elicit a desirable BMD response in older osteoporotic adults. The results of our study may guide osteoporosis treatment in older individuals.

A prospective comparative study on knee preservation surgeries in patients with osteoarthritis based on detailed evaluation of radiological parameters pre and post intervention
Authors: Bhushan Anand , Chaubey Shruti , Goel Rajesh , Vijay Akshat
Published: September 2022

Knee osteoarthritis is a common joint disease, with an incidence of 30% of the population older than 60 years. The current belief is that the load is distributed along the mechanical axis, which is generally medial to the centre of the knee. Osteotomies to change the mechanical axis has been long described as a treatment of medial compartment OA, and proximal fibular osteotomy being the recent addition. The authors aimed to evaluate the change in radiological parameters of the knee alignment and asses its statistical significance. It is a hospital based prospective pre and post interventional study done at New Hospital Medical College Kota. The Sample size was calculated to be 34 subjects at α-error 0.05 and study power 80%. Radiological parameters were assessed in terms of Femorotibial angle, Mechanical axis deviation and Lateral joint space under standard magnification. Radiological parameters depicting the change in knee alignment were found to be statistically significant. Also, it correlates well with that described in other established studies.
Evaluating probable predictors for fall related wrist fracture among the elderly population in a tertiary care hospital, Bhubaneswar

Published: September 2022

Wrist fractures are one among the common injuries of the elderly leading to reduced quality of life and impaired functionality, if not treated and restored adequately. Factors like asymmetry of vestibular function, decreased plantar sensation, unstable posture and functional disability have been more commonly associated with fall related wrist fractures among the geriatric population. Since wrist fractures are considered as an indicator for fracture incidence in the future specially for hip fractures, preventive measures like improving balance, function of the balance system in the inner ear and feeling in people’s feet can be timely adopted which in addition might be helpful in rehabilitation of patients with fractured wrist.

To determine effect of multi sensory training (MST) on posture (muscle strength), vestibular function, vibration perception, tactile sensation and functional ability compared to wrist stabilization training (WT) among elderly with fall related wrist fractures.

Experimental research design was adopted for the study among the 130 follow up cases of wrist fracture where 88 participants were randomized to Multi Sensory Training and 42 received Wrist stabilization Training. The training period was 12 weeks, with 4 supervised sessions by a physiotherapist and home exercises for both groups. Pre and post training measurements included Head Shake Test (HST), Semmes–Weinstein Monofilaments (SWM), Vibration perception Test, 10m Walk Test (10MWT), Five Times Sit to Stand Test (FTSTS), Activities Specific Balance Confidence (ABC) and Dizziness Handicap Inventory Scales (DHI).

FTSTS, ABC, DHI were found to be statistically significant between the 2 groups. In contrast to wrist stabilization training, MST was more helpful in improving HST (p=0.001).

Vestibular function among the cases of wrist fracture was better with Multi Sensory Training. It may be applied as a routine training intervention post fracture treatment. A robust sample size can be taken up to generalize its effectiveness.

This investigation on strain hardening, densification and workability of the Sintered aluminium- Chromium Carbide composition of (Al-Cr3C2 of 2, 4 and 6%) preforms subjected to upsetting were investigated in this research. Industrial practitioners needed the workability data and densification mechanisms to plan and envisage the failure strains. In the current study, under triaxial stress state conditions Al-Cr3C2 preform with primary preform densities and various aspect ratios were compressed. Strain hardening, densification behaviors of aluminium- Chromium Carbide be investigated by gradually increasing the load till the fracture occurs. The outcome of adding Cr3C2 to Al and the impact of aspect ratio on formability was also extensively investigated. We looked at the parameters of stress ratio, instant varying strain rate, work hardening exponent, instantaneous density coefficient and densification attained.
Assessment of Polyethylene Geomembrane Properties after Accelerated Thermal Ageing

Application temperatures and exposure environments are among the causes of premature antioxidant loss in polymer geomembranes. Therefore, over the long term, polymer degradation takes place which is reflected in geomembrane properties. In this work, accelerated thermal ageing of polyethylene geomembrane was carried out in a climatic chamber at 70℃ with 21% oxygen. The evolution of tensile properties, puncture resistance, and shore D hardness with exposure time was assessed. Changes in chemical and crystalline structure and melt flow index were made. According to the findings, geomembrane surface oxidation takes place in the polyethylene matrix after 9 months of exposure. This fact is confirmed by evaluating carbonyl, vinyl, and hydroxyl indexes. Uniaxial tensile properties, puncture resistance, and shore D hardness indicated slight changes after one year of exposure. While the crystallinity index, determined by XRD measurement, has shown an increase with exposure. Further, melt flow index measurements confirmed the absence of chain scission during the early exposure periods. However, for longer periods, chain scission reactions occurred and MI values increased moderately after five months of accelerated aging. All results indicated no significant bulk degradation while maintaining a certain mechanical resistance with applications under a temperature of 70℃. This temperature value is relevant in a waste storage center, but the studied geomembrane is not recommended for this case.

The high proportion of the immigrants from Russia characterized by the ethnic and religious diversity actualizes the economic and socio-cultural integration of immigrants to ensure the security and stability of society. To develop migrant integration programs in Russia at the national and regional levels and evaluate their effectiveness, it is important to analyze the experience of Spain, a country with the similar structure of migration flows and regional aspects of integration. The article presents the results of the analysis of the migrant integration policy in Spain. The key issues are: the assessment of migration flows to Spain and identification of the regional features of integration; the review of the measurement methods for evaluating the results of integration policies based on the system of indicators and indices. Particular attention is paid to investigating the possibility of using the Spanish experience of the integration in Russia. The empirical basis for the analysis includes the results of the 2010 Zaragoza Declaration, as well as the results of the Spanish investigations is to monitor the integration of migrants, statistical data from the Eurostat agency and the National Institute of Statistics of Spain. The study of the possibility of using the innovative measurement system regarding the integration of immigrants in Spain and its regions proposed by the team of authors led by D. Godenau was revealed. This proposal is relevant especially for the assess of the integration of migrants in Russia, especially in the field of labor relations, which is the most sensitive area of integration, due to the most pronounced discrimination in it.

The Language of Propaganda in Governance: the Nigerian Situation
Authors: Nwosu-Okoli Ifeoma , Anyachonkey Ngozi
Published: September 2022

Language is a unique gift to humanity by the Omniscient God. By means of language, we build or end a relationship, forge alliance, build bridges of unity and cooperation among peoples and groups. By means of language, also, we find a viable instrument to achieve participation and exclusion in political and diplomatic maneuvering. Formal or informal discourse may be achieved through vocal utterance, written medium or even paralinguistic features. Language, in effect, plays inestimable role in all aspects of life. This paper, in a special way, examines the impact of language in governance. Since English is Nigeria’s official language, the essay has, by purposeful random sampling, chosen the meta language of English, of all the myriads of languages spoken in Nigeria, to engage our discourse and to ascertain the impact of language in governance. Again, since charity, they say, begins at home (but should not end there), the essay has chosen Nigeria to query the impact of the English language in (political) governance. The paper upholds the platitude which holds that much is expected from the one to whom much is given. In view of this, the study asserts that political governance in Nigeria is hard work for the fact that Nigeria is a conglomerate of peoples, national groups and tongues yoked together by the Lugardian amalgamation of January 1, 1914. The salient index that wields the fragile nation state together is diversity, amidst mutual suspicion among the diverse ethnic groups. The essay uses literary or library research to probe into the recesses of language and language theories for recommending to the political leaders in governance how they should manage language so that our beloved nation is not set ablaze as a result of language mismanagement.
