Uncemented total hip replacement with impaction bone grafting in protrusio acetabuli
Authors: Agrawal Aman 
Published: January 2023

Protrusio acetabuli is a central acetabular defect resulting from migration of femoral head medial to Kohler’s line. Idiopathic central displacement of femoral head within the acetabulum is quite rare. However, it may be seen in arthritic hips secondary to rheumatoid arthritis, ankylosing spondylitis, previous trauma, osteomalacia, etc. Primary Total Hip Replacement (THR) in such cases is difficult because of the deficient medial bone, decreased peripheral bony support to the acetabular component and proximal and medial migration of the joint centre. Several techniques described previously in the surgical management of protrusio acetabuli include cemented acetabular components with cement alone or in association with morselized bone graft to reconstruct the acetabulum. However, cement has high rates of migration and loosening of cemented acetabular components in young patients leads to more revision surgeries within the first decade of implantation. The purpose of the study is to describe the technique and results of using impacted morselized bone graft with a porous coated cementless acetabular component in patients with protrusio acetabuli.A total of 20 primary THR’s (10 unilateral and 5 bilateral) in 15 patients (8 females and 7 males) with protrusio acetabuli were performed between 2018 and 2021, out of which 4 had mild,7 had moderate and 9 had a severe grade of protrusion. A total of 10 hips were affected by rheumatoid arthritis,3 by ankylosing spondylitis and 7 had unknown etiology. After the surgery, all bone grafts had united by the sixth month with no perceptible change in acetabular component position in any case. The mean preoperative Harris Hip Score was 48 which improved to 82 at the latest follow-up. 45% had excellent,33% had good, and 22% had fair results. There was no dislocation. The use of impacted morselized autograft with a cementless porous acetabular component is a good technique of restoration of hip biomechanics and sound fixation in cases of protrusio acetabuli.

Authors: Govil Gaurav , Tomar Lavindra 
Published: January 2023

The Covid-19 pandemic has affected the health in myriad ways. The direct affection may lead to respiratory infection. An indirect effect of Covid-19 has manifestations on the physical, mental and behavioural attributes in majority of the age groups. The forced restrictions, limited activities, and changed lifestyle have aggravated the deleterious effects of the sedentary lifestyles. The management of the physical activity for all age groups especially pre-adolescents took a relative back-seat during the Covid-19 restrictions with no immediate suggestions for an active treatment protocol strategy. The clinicians in general, emphasised on the conservative measures to manage the increased incidence of vitamin deficiency and osteopenia majorly with consultations based on telecommunication without clinical evaluation. The subsequent delayed assessment showed a profound negative impact amongst the pre-adolescents with significant progression of knee deformation and increased outpatient clinic presentation of genu valgus for management in later phase of pandemic. This has posed a unique Covid-19 post-pandemic manifestation of concern.The trilogy of Covid-19 restrictions induced poor physical activity, vitamin-D deficiency, and deformation of knees to valgus angulation have crippling effect in the pre-adolescent age-group. The delay in timely identification and medical management for the pre-adolescents has aggravated the joint deformation compromising the functional outcomes. The orthopaedic surgeons are now challenged and burdened to manage pre-adolescents knee deformity for corrective medical and surgical measures. On literature review, the guidelines are sparse for the paediatric orthopaedic management. The silent worsening with increased morbidity presents a matter of substantial concerns.An individualized management strategy for pre-adolescents is strongly recommended to manage this “silent” morbidity.

Published: January 2023

Chronic musculoskeletal pains are multifaceted, and Central sensitization is a potential pathophysiological mechanism underlying a group of chronic musculoskeletal pain disorders. Neurophysiology of pain education knowledge and patient satisfaction levels of chronic musculoskeletal pain subjects may contribute to central nervous system sensitization. Hence, the aim of the study was to evaluate the impact of neurophysiology of pain education knowledge and patient satisfaction levels on central sensitization in large population of patient with chronic musculoskeletal pain. The study included 200 chronic musculoskeletal pain subjects that persisted more than 3 months with average age of 43.93±13.62. A cross-sectional study used non probability sampling. Neurophysiology of pain Questionnaire (NPQ) to know the conceptualization of pain, mood rating scale(MRS) to measure patient’s mood fluctuation because of pain, pain disability scale (PDS) for evaluating patients ability to perform certain activity, central sensitization inventory(CSI) to measure nervous system sensitization and patients satisfaction scale(PSS) to understand patient’s satisfaction towards the treatment and health care provider were used. Descriptive and correlation analyses were used for analysis. The correlation analyses showed that patient disability scale negatively correlated with mood scale and positively correlated with the age, duration of the condition, impact of pain on ADL and central sensitization. And there was a positive correlation between patient satisfaction and impact of pain on ADL. The age, mood, duration of the condition and pain disability were the factors behind central sensitization in patients with chronic musculoskeletal pain. And the neuro physiology of pain knowledge had impact on pain disability and patient satisfaction.

Upper Body Posture Investigation in Young Track and Field Athletes
Authors: Radu Liliana Elisabeta , Petrea Renato-Gabriel 
Published: January 2023

Based on previous researches, it was identified how physical activity brings effects on the posture and physical development of a young body. The posture of the athletes is a large interest subject for the physical education and sports research field, mostly for the researchers who discovered that physical training affects body posture, even if there is no consensus on the direction of this effect. The main scope of the case study is to evaluate the anthropometrics variables and to evaluate the upper body posture using the APECS Pro version 6.2.0 developed by New Body Technology in young track and field athletes. The analysed group consisted of fourteen minor athletes (7 girls and 7 boys) with age between 11-13 years old. A minimum of two years of participation in athletics training, a frequency of 3 times/week training sessions, and participation on track and field contest at regional events, were criteria for inclusion in this study. Were assess anthropometric measurements (6 variables) and posture investigation (upper body posture in frontal plane – back view and sagittal plane, side view respectively). The results were performed by means, SD, and Independent Sample T-Test. Also, relationships between anthropometric variables and angular values of upper body posture in frontal and sagittal plane were analysed with Pearson correlation. Data analysis revealed asymmetry at the body alignment, head-neck, shoulder, scapulae, and axillae. It’s recommended to perform exercise sets during the session training or individually to improve the strength and the balance of strength to be able to keep the best posture daily life.
The anatomy of parasitism in financialised capitalism: Entitlement and the destructive nature of permissive neoliberalism
Authors: Leaman Jeremy 
Published: January 2023

This paper seeks to contribute to debates about the negative consequences of inequality, by examining the resilience of the failed and damaging doctrines of neoliberal supply-sidism in terms of the powerful hegemony of economic and political interests allied to the financial services sector, focussing the role of the UK in facilitating that hegemony. It deploys the concept “permissive neoliberalism”, signifying both the formal embedding of property rights over financial assets as the legal encoding of the short-term predatory hunt for “yield”, and the political toleration of criminal and criminogenic activity. The description of some of the most egregious examples of predatory financialisation illuminates the sanctification by the neoliberal state of ruthless value-extraction and the toleration of an increasingly chronic dependence on of the UK political economy on the City of London and its archipelago of secrecy jurisdictions.
The shorter second part of the paper charts the growth of a mindset of entitlement on the part of economic and political elites and the role of psychopathic narcissism in crafting a legitimating narrative of their hegemony. The chronic disorder in the allocation of humanity’s material and financial resources invites a strong conclusion that financialised capitalism is not simply “killing the host” qua sustainable economic order, but is threatening the very survival of humanity’s biosphere by blocking the deployment of financial and human capital at sufficient scale to rescue the world’s climate from catastrophe.
Ways of “showing love” in an intimate relationship – similarities and differences between women’s and men’s interactions
Authors: Czernecka Julita 
Published: January 2023

The aim of the article is to present the results of qualitative research into the ways women and men show love in heterosexual relationships and to indicate gender similarities and differences in this area. The analysis is based on references to traditional and modern models of femininity and masculinity. The respondents’ opinions were divided into two main areas – widely defined communication (gestures of tenderness, emotional support, behavior during misunderstandings) and specific activities (helping perform household duties or other activities for the partner, buying gifts, organizing free time, initiating sex). The analysis of the empirical material showed the interpenetration of patriarchal and modern models of femininity and masculinity in how women and men behave lovingly towards their partners. Both men and women draw inspiration from the repertoire of behaviors, as well as from traditional masculinity and femininity, evolving towards a modern model of femininity and masculinity that becomes more androgynous. In this way, they definitely expand the ways they show love, combining the more emotional, feminine ways with the more active, more traditionally “masculine” ones.

Published: January 2023

School reforms aim to achieve lasting knowledge for pupils. Some researchers have shown that lasting knowledge can be achieved through a cognitive-constructivist model of instruction, as pupils discover concepts themselves and are active in the classroom. In this paper, we aimed at investigating whether pupils who are exposed to a cognitive-constructivist model of instruction are more successful in solving mathematical tasks than those who are not exposed to a cognitive-constructivist model of instruction. For this purpose, we have designed an experiment involving 252 pupils of the 3rd grade of primary school: of these, 100 were included in the experimental group receiving constructivist mathematics instruction, while the remaining 152 pupils constituted the control group. The study showed that the experimental group performed better in solving mathematical problems which involve all three taxonomic levels according to Gagné.

Study and development of methods for predicting the physical and mechanical properties of thin wire and metal cord
Authors: Eltsova E. S. , Bobarikin Yu. L. , Martyanov Yu. V. 
Published: January 2023

Predicting the physical and mechanical properties of thin wire and metal cord will ensure an increase in the quality of latuned thin wire, a reduction in the number and time of technological pauses, and increase the manufacturability of metal cord twisting. Considering that the deformation manifests anisotropy of the properties of thin wire, the prediction of physical and mechanical properties and the degree of unevenness of deformation becomes an urgent task.The paper studies that an increase in the drawing speed of a thin wire leads to the acquisition of a more uniform and fine‑grained structure. The dependences of the physico‑mechanical properties of thin latuned wire after the metal cord is twisted on the speed of fine drawing are developed. The effect of the deformation rate on the microhardness of a thin steel wire is investigated. It is determined that in order to increase the productivity of metal cord twisting, it is necessary to bring the dependence of the increase in hardness and equivalent stresses in metal cord wires to a linear form by changing the speed of the twisting at its individual stages. For practical use, the dependences of the mechanical properties of a thin wire of strength class HT on the drawing speed are derived.During the analysis, the results were obtained, which are applicable in the design of new or modification of existing routes for drawing thin wire, as well as in the design of new metal cord structures.

ABSTRACTMicrofaunal assemblages of benthic foraminifera, ostracods, and tintinnids from two marine sediment cores retrieved from the Herschel Basin of the Canadian Beaufort Sea shelf document relationships with environmental parameters such as salinity, sea-ice cover, and turbulence. Cores YC18-HB-GC01 and PG2303-1 were collected at 18 and 32 m water depth, respectively. At these sites, sediment accumulation rates range between 0.6 and 1.7 cm yr–1 allowing a near-annual temporal resolution over the last 50 years. Multivariate analyses indicate that benthic foraminiferal assemblages respond primarily to food supply. Dissimilarities between the microfaunal assemblages of the two cores are mainly the result of bottom water salinity levels linked to water depth. High abundance of the benthic foraminiferal species Elphidium clavatum and occurrences of Elphidium bartletti point to varying, but relatively low, salinities at the shallow core site YC18-HB-GC01, which may be affected by variations in the summer halocline depth. Higher species diversity and more abundant Cassidulina reniforme and Stainforthia feylingi characterize the deeper core PG2303-1, which might reflect more stable conditions and higher bottom-water salinities throughout the studied time interval. The most important microfaunal shift of the last 50 years, observed in the shallower longer core YC18-HB-GC01, occurred at the turn of the 21st century. Prior to ∼2000 CE, the presence of Islandiella norcrossi indicates more stable and saline conditions. Since ∼2000 CE, increased abundances of Haynesina nivea and of the ciliate Tintinnopsis fimbriata suggest decreased salinity and increased turbidity. An increased abundance of Eoeponidella pulchella after ∼2000 CE suggests a concurrent increase in productivity in the last two decades. This shift is nearly synchronous with a decrease in mean summer sea-ice concentration, which can play an important role in bottom water stability on the shelf. Easterly winds can induce a reduction in the sea-ice cover, but also foster a westward spreading of the Mackenzie River plume and the upwelling of nutrient-rich Pacific waters onto the shelf. Both factors would explain the increased freshening and productivity of the Herschel Basin. The last two decades were also marked by a decrease in ostracod abundance that may relate to higher water turbidity. This study shows that combining information from benthic foraminifera, ostracods, and tintinnids provides a comprehensive insight into recent hydrographic/climatic changes in nearshore Arctic habitats, where productivity is critical for the food security of local communities.
Foraminifera Associated With Swirled Spartina Patens Beds on Perched Marshes Along the Rocky Coastline of Lunenburg County, Nova Scotia
Authors: Wilson Brent , Hayek Lee-Ann C. 
Published: January 2023

ABSTRACT
Perched marshes in Lunenburg County differ in exposure to prevailing waves (from most to least exposed: Crescent Beach, Blue Rocks, Feltzen South). We sampled the middle marsh, recording replicates’ dried masses. In picking stage 1 (PS1), the first 400 foraminifera, whether agglutinated or calcareous-walled, were picked and identified. From these data we calculated the Shannon Function H and compared the between-locale signals of benthic foraminifera using a relative-dominance index, ACW, for agglutinated and calcareous-walled foraminifera. Crescent Beach was a distinct locale with much medium-grained quartz sand and abundant allochthonous calcareous foraminifera (hence ACW &lt; 1). The other sites’ ACWs ranged from ∼50–100. There was a significant negative ACW:residue mass correlation. In picking stage 2 (PS2), the remaining agglutinated foraminifera were picked. The Feltzen South perched marsh yielded only Miliammina fusca, perhaps reflecting high %N and %C. Meanwhile, Trochammina inflata was abundant at Crescent Beach and Blue Rocks.

Abstract
—The study area is located within the Chernyshev Ridge, a fold–thrust structure, which is a promising area for oil and gas exploration in the Timan–Pechora province. Petroleum source rocks of Paleozoic (from Upper Ordovician to lower Carboniferous) deposits stripped by the Vorgamusyurskaya-1 well in the Tal’bei block of the Chernyshev Ridge were studied by lithological, petrographic, organic-petrology, and organic-geochemistry methods. Most of the section is characterized by low values of Corg (&lt;0.5%), genetic potential (S1 + S2 &lt; 0.5 mg HC/g rock), and hydrogen index (HI &lt; 100 mg HC/g Corg). Petroleum source rocks with elevated values of Corg (up to 0.9%), S1 + S2 (up to 2.1 mg HC/g rock), and HI (up to 277 mg HC/g Corg) were identified at different stratigraphic levels of the section: Upper Devonian (D3tm–sr), upper Silurian (S2gj), and Upper Ordovician (O3mt). The maceral composition of organic matter (OM) and the distribution of hydrocarbons in the saturated fraction of bitumens indicate that petroleum source rocks include only marine OM (type II kerogen). The degree of catagenesis of OM was estimated based on the bituminite reflectance (RVeq), Rock-Eval pyrolysis (Tmax), and conodont color alteration index (CAI). The available RVeq (0.63–0.84%), Tmax (430–443 °C), and CAI (1.5–2.0) data indicate that the entire Paleozoic well section is in the oil window (MC1–MC3). The new data refined the catagenetic zoning of the sedimentary section, according to which the OM reached the following gradations: MC1 in the lower Carboniferous and Famennian deposits, MC2 in the interval from the Frasnian to the upper part of the lower Silurian, and MC3 in the lower part of the lower Silurian and in the Upper Ordovician. The results of the study of petroleum source rocks and the type and maturity of OM will be the basis for basin modeling, which will increase the reliability of reconstructions of oil and gas formation at the Chernyshev Ridge.
