Authors: Kashayi-Chowdojirao Sreekanth , Khazi Syed Asif Hussain , Boddeda Sandeep , Patnala Chandrasekhar
Published: December 2022

Context:

Total hip arthroplasty (THA) is commonly performed through a posterior or a direct lateral (Hardinge) approach, and each one has merits and demerits.

Aims:

The purpose of this study was to examine the difference between the lateral and posterior approaches with respect to functional outcome, component positioning, intraoperative blood loss, and patient satisfaction.

Settings and Design:

This is a prospective comparative study of short- to mid-term outcome of cementless THA using two approaches.

Subjects and Methods:

Seventy hips satisfying our inclusion criteria were selected, of which 21 hips operated by lateral approach in supine position were included in lateral approach group (LAG), and 49 hips operated by posterior approach in lateral position were included in posterior approach group (PAG). Functional assessment was performed 1 day before surgery, 1 year after surgery, and at the latest follow-up using Harris Hip score (HHS). Component positioning of acetabular cup and femoral stem was assessed in plain radiographs at the latest follow-up. Generic satisfaction questionnaire was used to measure satisfaction after THA at the latest follow-up. Radiographic measurements (cup inclination, cup version, and femoral stem tip position) were performed postoperatively using low-centered pelvic anteroposterior and cross-table lateral hip radiographs.

Results:

At an average of 3 years and 6 months of follow-up, the mean HHSs were 88.05 and 90.32, respectively, in LAG and PAG; the difference was not significant (P = 0.178). The average inclination of the cup in LAG was 37.9° and in PAG was 45.02° with a significant difference (P = 0.00027), both of which are in the normal range. The cups were significantly (P ≤ 0.0001) more anteverted in the PAG (average angle of 27.69° vs. 16.14°). The mean blood loss was significantly more in PAG (510 ml vs. 436.67 ml; P = 0.04). Majority of femoral stems in lateral approach had their tips directed posterior. Nineteen out of 21 LAG patients and 45 out of 49 PAG were very satisfied/satisfied with their outcomes after THA.

Statistical Analysis Used:

Data were collected using prestructured data forms and analyzed with unpaired Student's t-test with 95% confidence interval.

Conclusions:

There was no significant difference in functional outcome and patient satisfaction at short- to mid-term follow-up between both approaches. The cup anteversion was significantly more in PAG. For better conclusions, other factors (i.e. immediate postoperative pain, and long-term survival), combined anteversion and spinopelvic parameters, have to be included in the study with a larger sample size.
Antibiotic-Impregnated Cement-Coated Intramedullary Nail in Primary Fixation of Compound Fractures of Tibial Shaft – A Comparative Study with External Fixator in Terms of Infection Control
Authors: Verma Rahul , Sharma Saurabh , Solanki Chetan , Prasad Ankit , Rao Mundalapati Gopala , Tandon Suneet
Published: December 2022

Introduction:

Compound tibial shaft fractures are conventionally managed by debridement and primary stabilization by external fixators, followed by definitive fixation after the wound healing; however, many problems such as infection, difficult soft tissue reconstruction, and psychosocial effects encountered. Hence, a technique of antibiotic-impregnated cement-coated intramedullary nailing has been advocated.

Aims:

The aim of the study is to compare functional and biological outcomes of antibiotic-impregnated cement-coated nail with external fixators.

Settings and Design:

This was a prospective interventional study.

Subjects and Methods:

A total of 20 patients with Compound Grade 3A and 3B (Gustilo and Anderson) tibial shaft fractures who met the inclusion and exclusion criteria from January 2020 to June 2021 were selected. Group 1 was operated with antibiotic-impregnated cement-coated nails. Group 2 was operated with external fixators. Clinical and laboratory parameters were used to evaluate infection control. Final follow-up was taken at 6 weeks.

Results:

The infection rate after nailing was 10% in Group 1 (1/10) and 50% in Group 2 (5/10). Intraoperative time taken for soft tissue reconstruction procedures after primary fixation such as flap cover and skin grafting was comparatively less in Group 1 (mean time – 32 min ± 6.23) compared to Group 2 (51 min ± 5.83). Duration between primary and definite fixation was comparably less in Group 1 (mean duration 5.7 weeks ± 0.45) compared to Group 2 (6.3 weeks ± 1.004).

Conclusions:

Primary antibiotic-impregnated cement-coated nail is better than external fixator in terms of infection control and providing stability in compound fractures of shaft of tibia.

Published: December 2022

Introduction:

Bone and joint infections are very common in eastern India. Due to the lack of authentic data on the type of bacteriology in our region, this study was planned.

Materials and Methods:

After ethical clearance, retrospective data of 2 years from 2019 to 2021 were collected. Out of 115 patients, 77 patients were included in the study whereas 38 were excluded due to nonbacterial infections and incomplete data.

Results:

The average age of patients was 21.14 years. Pediatric patients were 58.66%. The common clinical condition was chronic osteomyelitis, followed by septic arthritis. The most common bone affected was femur, followed by tibia. The most common organism noted was methicillin-resistant Staphylococcus aureus (MRSA) and coagulase-negative Staphylococcus aureus (CNSA). Gram-negative infections were also noted.

Conclusions:

Eastern India has a high incidence of bone and joint infection. MRSA followed by CNSA is the most common isolate affecting large bones such as femur and tibia.
Bone Names and “ization” in Orthopedics
Authors: Dharmshaktu Ganesh Singh
Published: December 2022

Various terms in orthopedics are formed using or incorporating the name of native bones and these terms then describe a clinical entity or a procedure. The term thus created, however, may or may not be directly related to the bone associated. There are a few interesting examples of such terms that are encountered in the orthopedic literature. A short recollection of those few notable terms that have the name of a known bone within their terminology is described here for general reading and knowledge.

Authors: Patel Ishani , Amin Tarkik K. , Makwana Vipul R. , Prajapati Mrudul M. , Patel Amit Virabhai , Modi Dhaval R. , Kavi Shivam K.
Published: December 2022

Introduction:

Distal humerus fractures are uncommon injuries that account for fewer than 2% of all adult fractures. The complex shape of the elbow joint, the adjacent neurovascular structures, and the soft-tissue envelope combine to make these fractures difficult to treat. The treatment usually consists of determining the injury mechanism and developing a treatment algorithm to regain full mobility of the joint.

Materials and Methods:

This is a prospective study of 20 cases of distal humerus intra-articular fracture treated by open reduction and internal fixation at our institute during 2017–2019. All the patients in this study were above 18 years of age. These patients were treated with open reduction and internal fixation either by paratricipital approach for fractures with minimal intra-articular comminution or by olecranon osteotomy approach for fractures with more intra-articular comminution.

Results:

In this study of 20 patients with distal humerus fracture treated with open reduction and internal fixation with ages ranging from 18–65 years, 13 (65%) were male patients and 7 (35%) were female patients. 12 (60%) patients had fracture on the left side, and 8 (40%) patients had fracture on the right side. 11 (55%) patients sustained fractures following the fall from height, and 9 (45%) patients had fracture due to a road traffic accident. Postoperatively, 2 (10%) patients had superficial infection; both patients recovered with antibiotics. In our study, 17 (85%) patients had excellent results, and 3 (15%) patients had a good result according to the Mayo Elbow Performance Score.

Conclusion:

Distal humerus intra-articular fractures require anatomical reduction of intra-articular components. Vigorous, active physiotherapy is a must for good results. Rigid internal fixation is best accomplished by low-profile anatomical plate fixation, which provides an optimal biomechanical stability; hence, early mobilization can be started, and a good functional outcome can be achieved with a low complication rate.
Functional Outcome of Volar Variable Angle Locking Compression Plate in Distal end Radius Fractures
Authors: Pawan Kumar K. M. , Hawaldar Sangamesh V. , Patil Manjunath
Published: December 2022

Background:

Distal end-of-radius fractures are one of the most common fractures seen worldwide, accounting for approximately one-sixth of all fractures. Closed reduction and cast immobilization have been the mainstay of treatment, but recently open reduction and plating with conventional plates have gained importance as they can be of great value in treating distal end radius fractures. This study is based on the latest innovation in this regard, the effectiveness of the volar variable angle locking compression plate in treating distal end radius fractures.

Aim and Objectives:

To evaluate the functional outcome associated with volar variable angle locking compression plate for distal end radius fractures and also to study the efficacy of the plate in capturing the fracture fragments.

Materials and Methods:

A retrospective study involving 30 patients with distal end radius fractures who were treated with open reduction and internal fixation using a volar variable angle locking compression plate. Patients admitted between November 2018 and November 2019 were included in this study. Clinical, functional, and radiological outcomes were used to assess the efficacy of the plate. Results were calculated using the Disabilities of the Arm, Shoulder and Hand (DASH) score questionnaire at the end of 1-year postsurgery. Follow-up data for all patients for 1 year were available in our medical records. The extent of the range of motion (ROM) at the wrist joint was noted.

Results:

53.3% of patients had excellent results, 36.7% of patients had good results, while 10% of patients had fair results. Almost all the patients had good ROM postoperatively except two patients. One of them developed wrist stiffness and another patient had reduced ROM due to noncompliance to the treating doctor's advice.

Conclusion:

Our study signifies the importance fragment specific fixation of distal end radius fractures. Patients were mobilized sooner than other accepted modalities of treatment. We conclude that volar variable angle locking compression plates are superior to the other accepted modalities of treatment for distal end radius fractures.

Authors: Babu Surapaneni Suresh , Velagapudi Nanda Gopal , Gani Shaik Abdul , Surapaneni Suprabha
Published: December 2022

Background:

Distal femur fractures are one of the most frequent fractures seen in high-velocity trauma, and they are associated with substantial morbidity if not treated properly. Stiffness, secondary arthritis, shortening, and disturbance in the activity of daily living can occur as a result of this fracture. Open reduction and internal fixation with locking compression plates (LCPs) is the preferred treatment. The anatomic contoured LCP for the distal femur has been found to provide one of the best outcomes in terms of anatomical reduction with joint congruity, soft-tissue healing, fracture union, and functional ability. This study was done to evaluate the functional outcome of distal femur fractures managed with LCP.

Materials and Methods:

Thirty patients with distal femur fractures were treated at our institute using LCP were analyzed for the outcome in terms of clinical, radiological union, and functional results.

Results:

Twenty-one patients were male and nine were female. The average age was 41.55 years with a range of 21–60 years. In 22 patients, cause of fracture was road traffic accidents and in eight were fall at various occasions. Twenty-one patients had right-side fractures. The average time for radiological union was 14.2 weeks. The average flexion of the knee was 107.16°. Functional outcome was assessed using Sanders' Functional Evolution Scale. The outcome was excellent in 30%, good in 40%, fair in 17%, and poor in 13%.

Conclusion:

Locking compression plating is an excellent internal fixation option for both extra- articular and intra-articular distal femur fractures, and it is particularly helpful in osteoporotic metaphyseal fractures.
Predictability of Degenerative Disc Disease by Lumbar Sagittal Alignment on Conventional Radiograph in Comparison with Cross-Sectional Magnetic Resonance Imaging
Authors: Madhuchandra P. , Pawankumar K. M. , Santhosh G. Sunil , Raju K. P.
Published: December 2022

Background:

Degenerative disc disease (DDD) affects approximately 80% of the population. Changes in the magnitude of lumbar lordosis significantly change the weight-bearing patterns in lumbar facet joints and intervertebral discs. It is essential to understand the contribution of hypo and hyperlordosis toward the development of disc degeneration disease.

Materials and Methods:

A retrospective study of X-ray and magnetic resonance imaging (MRI) of the lumbosacral spine of 200 patients with chronic low back ache. The lumbar lordotic angle was measured in a standing lateral radiograph using Cobb's method (between the lines drawn along the inferior end plate of D12 and the superior end plate of S1 vertebrae). DDD was assessed on MRI based on the Pfirrmann grading system. The correlation between the lordosis measured on the radiograph and DDD on MRI was assessed.

Results:

We analyzed the lumbar sagittal alignment effect on the degree of disc degenerative disease. Out of 200 patients, 70 had no disc degenerative disease (Grade I, II) whose Cobb's angle was 45°–75°. The remaining 130 patients showed disc changes (Grades III-V) on MRI and had Cobb's angle <45° or >75°. There was a statistically significant difference between Cobb's angle in normal and DDD patients with P = 0.009 (P < 0.05).

Conclusion:

DDD correlated with deviation from an optimal lumbar lordotic angle (Cobb's angle) of 45° to 75°. Deviation from optimal values would compromise the optimal weight-bearing conditions on the lumbar spine resulting in DDD. These results may well have implications for the diagnosis, prevention, treatment, and rehabilitation of DDD.

Published: December 2022

Pediatric rectal adenocarcinoma is a rare disease with an incidence of 1.3 cases per million children; these numbers have been on the rise in the past two decades. Standard management guidelines are yet to be established because of their rarity and complex range of issues that need to be simultaneously addressed. Here, we demonstrate the treatment approach in a 10-year-old girl who presented with bleeding per rectum and was diagnosed with low rectal cancer; the histopathology was moderately differentiated adenocarcinoma. After discussions by a multidisciplinary team, she underwent laparoscopic bilateral ovarian transposition followed by neoadjuvant concurrent chemoradiation therapy. On follow-up, she achieved a complete clinical response that was evaluated by triple assessment (clinical examination, pelvic magnetic resonance imaging, and colonoscopy). For the past three years, the patient is being followed up using the watch and wait strategy, which is not standard in pediatric patients, and has remained disease-free. We believe that this novel perspective will enable the future development of individualized yet standardized management protocols; thus, it may help in minimizing morbidities. We discuss the complexity involved in treating pediatric rectal cancers by quoting the current case, being the first of its kind, to the best of our knowledge.
Evaluation of the accessibility and its equity of the national public-private mix program for tuberculosis in Korea: a multilevel analysis
Authors: Son Hyunjin , Kim Changhoon
Published: December 2022

OBJECTIVES: To examine the effect of individual and area-level characteristics on the probability of public-private mix (PPM) support (PPM coverage) for tuberculosis (TB).METHODS: This study is a retrospective cohort design using TB reporting and treatment management data in Korea. We analyzed PPM coverage through multilevel logistic regression and empirical Bayesian estimation according to individual and area-level characteristics and their interaction.RESULTS: Patients aged 0-29 years, women, of Korean nationality, treated at a general hospital, a one-time reporting, urban areas, and the lowest deprivation index (DI) showed higher PPM coverage. Due to the cross-level interaction, PPM coverage in the urban areas (slope=-0.048, p<0.001) had a higher level but a steeper negative deprivation gradient than in rural areas (slope= -0.015, p<0.001). For a general hospital, the PPM coverage in urban is high but more significantly decreased than in rural areas with the higher DI (urban: slope=-0.047, p<0.001; rural: slope=-0.031, p<0.001). For clinics and hospitals, the effect of DI did not appear in urban areas, but in rural areas, the higher the DI, the higher the PPM coverage with a slope of 0.046 (p<0.001) and 0.063 (p<0.001), respectively.CONCLUSIONS: The PPM program created a significant disparity in PPM coverage between urban-rural areas and type of healthcare provider according to DI. Considering the high risk of TB incidence in areas with higher DI, institutional improvement and program redesign are needed to improve accessibility and equity.

OBJECTIVES: Vaccination is one of the most important strategies to contain the spread of coronavirus disease 2019 (COVID-19). Vaccination in children is dependent on their parents, making it important to understand parents’ awareness and attitudes toward vaccines in order to devise strategies to raise vaccination rates in children.METHODS: A web-based nationwide survey was conducted among Korean parents of 7-year-old to 18-year-old children in August 2021 to estimate parents’ intention to vaccinate their children against COVID-19 and identify key factors affecting parental acceptance and hesitancy through regression analysis.RESULTS: Approximately 56.4% (575/1,019) were willing to vaccinate their children against COVID-19. Contributing factors to COVID-19 vaccine hesitancy were being a mother (adjusted odds ratio [aOR], 0.36; 95% confidence interval [CI], 0.25 to 0.52), a lower education level (aOR, 0.83; 95% CI, 0.70 to 0.97), hesitancy to other childhood vaccines (aOR, 0.78; 95% CI, 0.64 to 0.96), and refusal to vaccinate themselves (aOR, 0.08; 95% CI, 0.02 to 0.20). Having older children (aOR, 1.20; 95% CI, 1.13 to 1.28), trusting the child’s doctor (aOR, 1.19; 95% CI, 1.07 to 1.32), positive perceptions of the COVID-19 vaccine’s effectiveness (aOR, 2.60; 95% CI, 1.90 to 3.57) and perceiving the COVID-19 vaccine as low-risk (aOR, 1.68; 95% CI, 1.27 to 2.24) were associated with COVID-19 vaccine acceptance. Concerns about adverse reactions were the most common cause of hesitancy.CONCLUSIONS: Providing parents with accurate and reliable information on vaccine effectiveness and safety is important to increase COVID-19 vaccine uptake in children. Differential or targeted approaches to parents according to gender, age, and their children’s age are necessary for effective communication about vaccination in children.

Antigen detected in urine for the diagnosis of opisthorchiasis has a low daily variation; however, the longer term variability in antigen concentrations is unknown. In this study, we prospectively monitored Opisthorchis viverrini antigen concentrations for 30 consecutive days and at subsequent monthly intervals in a cohort of opisthorchiasis-positive individuals. On the basis of the monoclonal antibody–based ELISA, the profiles of antigen-positive rate and antigen concentration exhibited no significant change over 30 days with a mean proportion positive of 87.1% (range 73.7%–100%), and the average antigen concentration was 29.7 ± 2.2 ng/mL (mean ± SE). The urine antigen concentration at baseline was similar to the subsequent measurements at 2, 4, 6, and 10 months in the follow-up study (P > 0.05). The consistency and low daily and long-term fluctuation of O. viverrini antigen in urine demonstrates the reliability of urine assay for diagnosis of opisthorchiasis.
Hybrid Capacitive Deionization with Ag-coated Activated Carbon Electrodes for Nickel Treatment
Authors: Yoon Hongsik , Min Taijin , Lee Gunhee , Jeon Minkyu , Oh Minsub , Kim Areum
Published: December 2022

Nickel (Ni) is an essential resource in many industries. However, as the industrial use of Ni increases, its impact as an environmental pollutant has also increased. Accordingly, effective Ni treatment processes are required. In this study, hybrid capacitive deionization (HCDI) with an Ag-coated activated carbon (AC) electrode was proposed as a Ni treatment. The deionization capacity of the HCDI system with Ag coating was 66% higher than that of the membrane capacitive deionization system. In addition, as the applied potential increased from 0.5 V to 1.1 V, the deionization capacity also increased from 10 mg/g to 18 mg/g, although the charge efficiency decreased from 84.6% to 77.2%. However, when the applied potential was 0.9 V or more, the pH of the effluent exceeded the drinking water range, which appeared to be caused by the electron transfer reaction of Ni ions under a high applied potential (0.9 V or more). In terms of energy consumption, HCDI with Ag-coated electrodes achieved 0.24 Wh/g-NiCl2 as a minimum value. The results of this study demonstrate the potential of capacitive deionization (CDI) for Ni treatment.
Estimating Biological Reference Points of the Pink Shrimp, Farfantepenaeus notialis (Perez-Farfante, 1967) Targeted by Shrimp Trawlers in Sierra Leone
Authors: KONOYİMA Komba Jossie , SHOWERS Percival Arthur Timothy
Published: December 2022

Time series of catch and effort data for Farfantepenaeus notialis were analysed in ‘R’ using a data limited state-space Bayesian Catch-maximum Sustainbale Yield (CMSY) method for stock assessment from catch (tonnes) and abundance data (t/day). The study categorically compared the status of F.notialis in two periods (1981-1996) and (2008-2018) denoted as periods I and II, respectively. Results for management based on Bayesian Schaefer model (BSM) analysis for Period I gave (Prior relative biomass (B/k) = 0.06; MSY = 2.25t , 95% CL = 1.98 - 2.56; Fmsy = 0.379 yr-1 , 95% CL = 0.29 - 0.495; Bmsy = 5.94t , 95% CL = 4.69 - 7.51; Biomass = 4.78t; B/Bmsy = 0.806; Fishing mortality = 0.583yr-1 and Exploitation rate, F/Fmsy = 1.54) while that of Period II showed (Prior relative biomass (B/k) = 0.35; MSY = 0.662t, 95% CL = 0.567 - 0.773; Fmsy = 0.421yr-1 , 95% CL = 0.314 - 0.563; Bmsy = 1.58t , 95% CL = 1.22 - 2.04; Biomass = 1.09t; B/Bmsy = 0.69; Fishing mortality = 0.532yr-1 and Exploitation rate, F/Fmsy = 1.27). By implications, all estimated biological reference points portrayed an overfished status of F.notialis in 1989-1996 and in 2008-2018. Stock recovery measures are strongly advised for the stock in Sierra Leone.

Authors: QARANJIKI Abdolsaleh , KIRKAĞAÇ Mine
Published: December 2022

In this study, Artemia parthenogenetica was fed with either Spirulina (S), yeast (Y), rice bran (R), oat (O) or their combinations in 10 experimental groups in triplicate for 20 days in laboratory conditions and growth, biomass, feed conversion rate (FCR), specific growth rate (SGR), survival rate, crude protein, crude lipid contents were determined. The highest average body length obtained at the end of the experiment was 2.805±0.003 mm in treatments (S) and (SYR), and the highest average individual dry weight was 23.057 µg in treatment (S). The mean biomass changed between 167.2±0.003 mg and 115.7±0.012 mg. The highest biomass value was 20.9 g/m3 in treatment (S), followed by 20.5 g/m3 in treatment (SYR). The highest FCR was found to be similar in (S) and (Y) with 1.14±0.02. SGR was 1.01±0.001 in all experimental groups. The highest survival rate was in treatment (S), and overall it ranged between 78.22±1.78 - 90.64±0.06%. The highest crude protein contents of Artemia were found in (SR) and (S) and the highest lipid content was found in treatment (O). As a result, it is thought that combinations of by-products such as rice bran and yeast together with microalgae will be economical in the cultivation of Artemia parthenogenetica.
Review of the Monograph “Women and Family Life in Early Modern German Literature” by Elisabeth W. Nivre
Authors: Lebedeva Irena V.
Published: December 2022

This paper reviews a monograph by the Swedish Germanist Elisabeth Waghall Nivre, “Women and Family Life in Early Modern German Literature”. The monograph is published by Camdan House, edited by James Hardin, 2004. ISBN: 1-57113-197-3. My interest in the monograph stems from its unique area of research: the representation of gender roles in sixteenth-century German-language fiction. Despite the popularity of gender studies and the extensive corpus of works on the history of gender, there are few scholarly works in this particular area. A glance at E. Nivre's monograph allows to argue that although the monograph was published almost twenty years ago, its main observations and conclusions are still relevant today.

Energy transition implies a larger share of the intermittent renewable energy sources connected to the power grid. These utilities can change their production within a short period of time, thus, significantly affecting the voltage conditions and load flows in the grid. This adds to the complexity in achieving required reliability and stability of the system. Proper and timely insight into the grid parameters plays an important role in regulation of such power system. Implementation of Phasor Measurement Units (PMUs) provides information about electrical parameters of the grid with as much as microsecond precision. Therefore, possible occurring dynamical processes could also be observed and regulated in a proper manner. Considering PMU can give information regarding voltage phasor as well as currents of adjacent branches, the observability of the system can be achieved even if some nodes are not equipped with their own PMU. Furthermore, installation of PMU in every node is not economical solution considering the size of the power grid and the number of PMUs accordingly. One should assess the sufficient number of PMUs cautiously and locate them carefully in order to maintain observability, but also to reduce expenses as much as possible. In the grid topology with a vast number of nodes and branches, the usage of metaheuristic optimization algorithms with adequate criteria function and limiting conditions could reduce the computing time compared to the linear and non-linear programming algorithms. In addition, the quality of such solution is also preserved. In this paper, the usage of genetic algorithm is proposed in order to determine the number and position of PMUs for several different grid samples.

Published: December 2022

The design of the modular plasma guns of an erosion type that operate in the pulse-periodic mode has been described. The injection of the electrode and dielectric materials occurs due to the combination of many processes initiated by the high-voltage surface discharge. The guns with the dielectrics of (C2H4)n and (C2F4)n types have been
compared. Optical spectrograms of discharges for a (C2F4)n dielectric have been obtained. The radial and axial spread of sprayed components that are the part of plasma guns has been specified and the composition of the sediments deposited on the targets has been defined.

Published: December 2022

Peculiarities of the time dependence of the plasma parameters of a pulsed discharge with a hollow cathode in low-pressure argon were experimentally determined when using two types of pulsed high-voltage power sources – voltage and current sources (pulse duration up to 10 ms, voltage up to 10 kV). It is shown that the use of pulsed current sources provides significantly more stable discharge glow in the working range of argon pressure
variations (2.5…10)10-4 Torr. At the same time, the temperature of plasma electrons of the discharge which was powered by a voltage source, was several times higher and could reach 40 eV.

Authors: Awan Khurram Zafar , Abdullah Muhammad Ibrahim , Usman Muhammad
Published: December 2022

Globalization trends have been increasing all over the world and firms are overly emphasizing advanced technologies in the business world for gaining competitive advantages. While disruptive innovation is also a trigger for these firms to adapt and capture lower-end markets. This is a big challenge for the top managers of organizations to derive disruptive innovation by encouraging their subordinates for utilizing the knowledge process capabilities and creating novel ideas. The purpose of this study was to examine the relationship of knowledge process capabilities with disruptive innovation of the manufacturer and service sector small and medium enterprises. Data was collected from 194 senior managers of manufacturer and service sector SMEs in Pakistan (N = 194) and valid scales were used for measuring all constructs of this study model. SPSS and AMOS programs were used for analyzing the CFA of the measurement model and SEM of the study model. The study results indicated significant and positive relationships between knowledge process capabilities and subordinate creativity and disruptive innovation. Furthermore, subordinate creativity was completely mediated in the relationship between knowledge process capabilities and disruptive innovation. This study contributed to the literature on knowledge management and innovations. This is a cross-sectional study and can guide SMEs to adopt disruptive innovation for capturing low-end markets where lower-stream customers are demanding cheap products/services. Through practicing this study model, practitioners, researchers, and CEOs of SMEs can foster disruptive innovation.

Authors: Khalid Aliya , Ashraf Samina , Aleem Arishmah
Published: December 2022

Social Inclusion is an important and extremely desirable phenomenon for persons with disabilities(PWDs). It is the gateway to creating the sense and opportunities for PWDs by recognizing being as integral and potential human resources and a responsible segment of society.  In addition to the lack of research and policies that have been formulated from time to time to emphasize the concept and importance of the Social Inclusion of PWDs’, the traditional response of the community towards PWDs has deterred the social inclusion of PWDs.  The basic theme of this research study was to explore the efforts made by community members for the social inclusion of PWDs in the Community Care context.  A qualitative research method was used to conduct the study. At first, the document -analysis of previous research studies was made to explore the efforts made by the Government and policymakers for the social inclusion of PWDs in the COVID-19 endemic scenario. The open-ended interviews were conducted with the 20 professionals related to special education and social welfare fields to explore the efforts made by the community stakeholders as an element of community care to deal with social restrictions for PWDs and foster their social inclusion to make them productive members of society. The content -analysis reflected that no significant effort has been made at the governmental level for the social inclusion of PWDs d. Finally, the study suggested two Social Inclusion models; 1) Personal Social Services Model (PSSM) and 2) the Social-Ecological Model (SEM) of Social Inclusion which deals with the Individual, Interpersonal, Organizational, Community, and Socio-Political Factors of Society.

Published: December 2022

Herd management and nutrition strategies against increasing negative effects of global warming on farm animals have been the subject of significant debates in recent years. The fact that the changes in the environmental conditions are directly related to the habitats of the animals and the conditions inside the barn can affect the farm animals negatively. Although effects of heat stress differ according to species, especially high-yielding dairy cattle exposed to heat stress, respond with various interactive mechanism such as physiological, biochemical, immunological, anatomical and behavioral. Therefore, with the selection practices that have been going on for many years to improve the yield characteristics of the animals significantly increased. In this respect, the increased heat load in the body of dairy cattle due to the high productivity decreases their tolerance to environmental conditions. This situation adversely affects the productivity of cows with high breeding value. Yield losses, varying according to some factors about heat stress, can be partially explained by decreasing feed intake as a result of a series of hormonal responses affecting appetite center. However, the physiological requirements of cattle must be defined in order to develop appropriate strategies to reduce or eliminate the negative effects of heat stress. In this review, the variations in physiological, biochemical and behavioral mechanisms originating from heat stress in dairy cattle and the care, nutrition and herd management strategies that can be applied to eliminate or reduce the negative effects were discussed.

P L Powar and GRK Sahu [14] noticed that the fixed point may not exist for some self maps T defined on a set X. To deal with such cases the idea of Serendipity fixed point had been introduced by P L Powar in 2015. Considering the lighter concept of completeness viz. weak completeness, the existence and uniqueness of Serendipity fixed point had been established under contraction condition. In this paper we established the result for existence of serendipity fixed point under the PGA contraction [15] defined by Akhilesh Pathak in 2018. This idea may be useful in solving or simplifying the problems which are totally based on fixed point theory.
