Context.—
It is known that a subset of cases of classic Hodgkin lymphoma (CHL) with B-cell–rich nodules (lymphocyte-rich CHL) exhibits morphologic and immunophenotypic features that overlap with nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL), raising diagnostic difficulties that can be resolved in most cases by performing an adequate battery of immunohistochemical studies.

Objective.—
To fully characterize cases of T-cell–rich Hodgkin lymphoma where a specific diagnosis of NLPHL (ie, pattern D) or CHL could not be made even after complete immunophenotypic investigation.

Design.—
The clinical, immunomorphologic, and molecular (when applicable) presentation of 3 cases of T-cell–rich Hodgkin lymphoma was thoroughly investigated.

Results.—
These 3 cases harbored lymphocyte-predominant–like and Hodgkin and Reed-Sternberg–like cells that partially expressed B-cell and CHL markers and were negative for Epstein-Barr virus–encoded small RNA, in a T-cell–rich background with residual follicular dendritic cell meshworks; 1 case had frequent and the other 2 cases scant/absent eosinophils and plasma cells. Two patients with advanced-stage (III or IV) disease presented with axillary and supraclavicular lymphadenopathy, respectively, and without B symptoms. These patients underwent NLPHL-like therapeutic management with 6 cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin hydrochloride [hydroxydaunorubicin], vincristine sulfate [Oncovin], and prednisone) chemotherapy; both are in complete remission 7 years posttherapy. One patient presented with stage I disease involving an internal mammary lymph node without B-symptoms and was treated with surgical excision alone; this patient is also in complete remission 1 year later.

Conclusions.—
These cases illustrate overlapping features of T-cell–rich NLPHL and CHL with neoplastic cells expressing both B-cell program and CHL markers. This underrecognized overlap has not been fully illustrated in the literature, although it portrays a therapeutic challenge. These neoplasms may deserve in-depth investigation in the future that may bring up diagnostic or theragnostic implications.

Authors: Li Xiao , Xie Hongyu , Fu Yunfeng , Zhang Xiaofei , Dong Xiaohui , Ji Ying , Lu Weiguo , Wang Xinyu 
Published: December 2023

Context.—
Noninvasive self-sampling is a convenient option that may be highly accepted by women for home-based detection, which could increase the screening rate for cervical cancer (CC) and reduce its incidence and mortality.

Objective.—
To compare the distribution of high-risk human papillomavirus (hr-HPV) between the vulva and cervix and to explore the clinical value of vulvar HPV detection in CC screening.

Design.—
The study was nested within a clinical trial on a recombinant HPV 9–valent vaccine for women ages 20 to 45 years. Women with paired vulvar and cervical specimens were included and underwent cytology and HPV detection. The consistency of HPV detection between vulvar and cervical specimens was evaluated using Cohen κ statistics. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were used to evaluate the diagnostic accuracy of primary CC screening. The primary end points were cervical intraepithelial neoplasia (CIN) grade 2/3 or worse (CIN2+/3+).

Results.—
A total of 7999 women were enrolled, and 83/33 cases were diagnosed as CIN2+/CIN3+. The HPV-positive rate in vulvar specimens (1785 of 7999; 22.32%) was higher than that in cervical specimens (1390 of 7999; 17.38%), and there were no significant differences in the distribution of hr-HPV genotypes between the vulva and cervix in patients with CIN2+/CIN3+. Vulva-based HPV primary screening showed sensitivity, specificity, PPV, and NPV comparable to those for cervix-based HPV primary CC screening in the detection of CIN3+.

Conclusions.—
The distribution of vulvar and cervical HPV was similar in patients with CIN2+/CIN3+. Vulva-based HPV primary CC screening had acceptable diagnostic efficacy and might be used as a modality for primary CC screening.

Published: December 2023

In the n+(p+)−p(n) crystalline (X≡ CdTe or CdSe)-junction solar cells at 300K, due to the effects of impurity size, temperature, heavy doping, and photovoltaic conversion, we show that, with an increasing donor (acceptor)-radius rd(a), both the relative dielectric constant and photovoltaic conversion factor decrease, and the intrinsic band gap (IBG) increases, according to the increase in photovoltaic efficiency, as observed in Tables 1-5, being in good accordance with an important result obtained by Shockley and Queisser (1961), stating that for an increasing IBG the photovoltaic efficiency increases. Further, for highest values of rd(a), the limiting highest efficiencies are found to be given in Tables 4, 6, as: 26.55 %, and 23.69 %, obtained in such n+(p+)−p(n) crystalline (CdTe, or CdSe)-junction solar cells at the open circuit voltage Voc=0.82 V, and 0.89 V, respectively, and at T=300 K. Furthermore, from the well-known Carnot-efficiency theorem, as given in Eq. (46), being obtained from the second principle of the thermodynamics, and from the above results of limiting highest efficiencies, the corresponding highest hot reservoir temperatures, TH=408.4 K, and 393.1 K, respectively. Thus, as noted above, ηmax. and TH both increase with an increasing IBG, for each (X≡ CdTe, or CdSe)- crystal at T=300 K≡TC.

Published: December 2023

Background: Paramedical staff are essential to healthcare services and often encounter negative life events that can influence their psychological well-being. This research aimed to elucidate the connection between negative life events and the psychological well-being of paramedical personnel in Multan City, Punjab, Pakistan.
Methods: The study utilized a correlational research approach and involved a purposive sample of 196 paramedical staff from multiple medical institutions. The Negative Life Events Scale (Wills et al., 1992) and the Psychological Well-being Scale (Ryff & Keyes, 1995) were used as study instruments. Pearson's correlation coefficient was used to evaluate the relationship between the specified variables.
Results: The analysis revealed a significant negative relationship between negative life events and psychological well-being (r = -0.48, p < 0.01). Negative life events were found to be a significant predictor of psychological well-being, explaining 23% of the variance in well-being assessments. The paramedical staff who experienced a higher frequency of negative life events reported lower levels of psychological well-being.
Conclusion: The results of this study shed light on the importance of addressing the negative impact of life events on the psychological well-being of paramedical staff. These findings serve as a call to action for the development of specialized interventions and support structures that can help these healthcare professionals cope with the effects of these events. By proactively addressing these concerns, institutions can create a more supportive environment for staff and improve their overall well-being. These insights have the potential to inform institutional policies, support mechanisms for staff, and future research into mental health considerations in healthcare environments.
Review of Technological Advances in High Temperature Overhead Line Composite Conductors

Published: December 2023

ACSR (Aluminium Conductor Steel Reinforced) conductors consisting of pure aluminum wires helically stranded around a core of high strength galvanized steel core wires are widely used in overhead transmission line applications. While the steel wires provides the required strength, the outer aluminium serves as electricity conducting member. The thermal rating or ampacity of conductors is the maximum current that a circuit can carry within the temperature limits as dictated by the allowable conductor sag or by the annealing onset temperature of the conductor, whichever is lower. On a continuous basis, ACSR may be operated at temperatures up to 100°C without any significant change in the conductor’s physical properties. Above 100°C, aluminum wires loses tensile strength over time and becomes "fully annealed" giving rise to increased thermal expansion of the conductor; this causes excessive sagging reducing the clearance between the ground and the energized conductors.
While, the electric utilities are posed with increased challenges of production of additional capacities and building new transmission circuits to meet the ever growing demand and the high cost and environmental restrictions of constructing new lines, methods are being explored to increase their capacity with minimum changes in the existing towers. Replacement of the existing conductor with a advanced high temperature composite (HTC) conductors operating upto temperatures of 200°C with reduced sagging characteristics have been attempted and an increase in capacity of 30-80%, can be achieved through application of these composite conductors.
The advanced HTC conductors with varied combinations of core material and outer conducting wires are being tried so as to achieve wide ranging properties. In general, HTC conductors features the combinations of either soft aluminum wires with ultra high strength steel or temperature resistant aluminium with or fiber reinforced metal/polymer matrix composites as the core. Both the alumina fiber reinforced temperature resistant aluminium metal matrix composite and the carbon fiber reinforced high temperature polymer resin composite wires as the core material appears to have favorable applications. The comparative performance of the HTC depends on the degree to which both outer aluminum strand and reinforcing core’s physical properties are stable at high temperature and on the elastic, plastic, and thermal elongation of the combined HTC.
The summary of various developments realized in the area of composite conductors and their relative merits and demerits have been discussed in detail.

This paper presents the approach for qualification of indigenously developed compressor impeller for aero engine application. Indigenisation is understood to be the most important tool for effective technical empowerment of a developing nation. Indigenisation philosophy is adopted by several countries in various fields such as power, infrastructure, aerospace, military equipments and etc. Indigenous development fills the technical, financial and time frame gap between imports and ab-initio design and development. Hence, for a healthy technical growth of any developing nation, Indigenous development activities should go along with ab-initio design activities. Indigenous development has become an integral process of activities of Defence sectors due to its potential benefits. Indian defence imports stands at staggering 65 % of the total defence acquisition. In order to make the best use of indigenization opportunities in the defence sector, conservative figures would suggest an amount more than 100,000 crores. This gives an indication of the potential and benefits of indigenous development in defence sectors.
In this paper a methodology for indigenous development of a military turboshaft engine compressor impeller is discussed. This activity has enabled uninterrupted supply of the component and a substantial Foreign Exchange savings. This paper specifies the various tests conducted over the forging. It also brings out the results of cyclic spin test on the component for 22500 cycles as life substantiation, 15% and 22% over speed test as structural integrity substantiation and 150 hours type test on engine for quality and assembly substantiation.
This indigenous development procedure described in this paper can be readily extended to suitable critical aero engine component.

Authors: Vinayaravi R. , Kumaresan D. , Asraff A. K. , Muthukumar R. 
Published: December 2023

Vibration plays a vital role in many structural elements. Excessive vibration can cause failure due to resonance and fatigue, malfunctioning of critical components, etc. Vibration can be controlled using passive, active and hybrid control systems. This paper presents the experimental studies carried out on the behaviour of impact dampers, which belong to the category of passive vibration control devices that are used to attenuate vibration of discrete and continuous systems. Impact damping is a technique for improving damping of a dynamic system by means of dissipation of energy due to collision of a free mass on the main mass.
Experimental studies are carried out for forced vibration conditions by giving sinusoidal varying forcing function to the cantilever beam system using an exciter system and the time/frequency response function is determined. Impact mass is placed at free end of cantilever beam and the system is given constant base excitation and the damping of the system is studied by varying the frequency. Experiments are conducted for various mass ratios with different impact mass materials and the results are compared with theoretical predictions.

В статье приведены результаты исследований влияния бурового шлама на свойства цементной пенобетонной смеси и пенобетона естественного твердения. Для обустройства и строительства объектов нефтегазовых месторождений предложено использовать буровой шлам (побочный продукт нефтедобычи) в качестве мелкого заполнителя при изготовлении конструкционно­теплоизоляционного пенобетона. Замена кремнеземистого песка на такой шлам позволит решить проблемы ресурсного обеспечения неавтоклавного пенобетона каче ственным мелким заполнителем на местах обустройства месторождений, а также утилизировать буровой шлам как отход. Час тичная или полная замена песка на буровой шлам в технологии приготовления неавтоклавного пенобетона позволяет увеличить прочность последнего на сжатие в возрасте 28 сут. Исследования проведены в аккредитованной испытательной лаборатории «Стромтест» Томского государственного архитектурно­строи тельного университета. Разработанный состав цементного пенобетона рекомендован для строительства монолитных стен на строительной площадке или при изготовлении в заводских условиях стеновых блоков для индивидуального жилищного строительства.
The article presents the results of drill cuttings effect upon the properties of cement foam concrete mix and naturally cured foam concrete. Drilling cuttings (a by-product of oil extraction) are suggested to be used as a fine aggregate for constructive and heatinsulating foam concrete for the development and construction of oil and gas fields. The replacement of silica sand with cuttings will address the problem of resources for producing non-autoclaved foam concrete with high-quality fine aggregate at field development sites, and also utilize drilling cuttings as a waste product. Partial or complete replacement of sand with drill cuttings in the technology of non-autoclaved foam concrete allows to increase the compressive strength of the latter at the age of 28 days. The research was carried out in the accredited Stromtest testing laboratory of the Tomsk State University of Architecture and Civil Engineering. The developed composition of cement foam concrete is recommended for the construction of cast-in-situ walls at the construction site or for the manufacture of prefabricated wall blocks for individual housing construction.
