Published: January 2025

Cultural imperialism refers to the dominance of media content from developed countries, often characterized by technological and economic superiority, which influences the culture of developing countries and leads to a preference for foreign cultures. This study analyses the cultural influence of Western cable television channels on Nigerian audiences, focusing on viewer perceptions and behavioural changes. Specifically, the research examines how channels such as DSTV, GOTV, and Star Times shape viewers' cultural preferences and behaviours. Employing a mixed-method approach, the study combines quantitative data from surveys and qualitative insights from interviews. Respondents were selected through purposive and random sampling, targeting individuals with access to cable television. The relevance of cultural imperialism theory is evaluated in the context of Western television's influence on Nigerian audiences. Findings reveal that while Western television channels are accessible, their influence on Nigerian viewers is limited. Instead, viewers strongly prefer local cultural elements such as music, language, dress, and locally relevant information. Observed behavioural changes, such as shifts in entertainment choices and social practices, also indicate a selective adoption of foreign content, often filtered through a local lens. Additionally, the study identifies erratic power supply as a significant factor limiting the impact of cultural imperialism in Nigeria. These findings challenge the assumption of Western media dominance and suggest that local culture remains resilient despite global media influences. The study's implications highlight the need for policies that support local content production and cultural preservation in the face of globalization.

Sustainability and livestock: a doable combination
Authors: Chiariotti Antonella
Published: January 2025

Sustainable development means meeting the needs of the present while ensuring future generations can meet their own needs (European Commission). Rapid urbanization, increased purchasing power, and dietary change drive demand for richer diets and animal-origin proteins, leaving more than 868 million undernourished citizens worldwide and 850 million living in developing countries. Food security could be granted to large populations by reducing food waste, which accounts for 1.3 billion tons per year, or implementing livestock farming and promoting a sustainable food demand. With economic progress and the world’s growing population, estimated to reach more than 9 billion people in 2050, animal proteins will increase as meat and milk demand. Nevertheless, ruminants produce methane, which accounts for most of the agricultural sector emissions (5.8% of the total anthropogenic), raising concerns about their production. If ruminant livestock increase, methane production increases, accelerating global warming inevitably. Depending on resource quality, environmental factors, and social and economic contexts, various types of livestock production systems may vary considerably in sustainability. These livestock systems include extensive grassland, intensive landless, mixed, and family farming systems. Massive worldwide research has investigated the effect of various mitigation strategies. None- theless, the under-representation of certain strategies, geographic regions, the calculation’s robustness, and long-term studies are the main limitations in providing an accurate quantitative estimation of the respective mitigation potential under diverse animal production systems. Ruminant livestock is important not only for producing nutrient-dense meat and milk for human diets but also for providing hides, fiber, manure, and animal power for farming and transportation in many countries and contributing to biodiversity. To obtain this, they eat grass and legume plants that would be inedible to humans or live on land unsuitable for cultivation. Livestock also contributes to muchneeded income for family farmers in developing countries. The buffalo (Bubalus bubalis), represented by a total of 204 million head (3.9 % increase in the last ten years), could play a strategic role due to its peculiar characteristics: the high ability to convert fiber into energy, the longevity, and the adaptation in extreme areas with cold or hot-humid climate where other ruminants cannot thrive. Moreover, it contributes to the sustenance of many people living in rural areas. A multidisciplinary approach considering the environment, animal health and welfare, and social and economic contexts is requested to increase the sustainability of livestock.

The growth of the world population that will occur in the next 30 years will be responsible for an increase in animal-derived food and proteins of animal origin. The livestock sector will be obliged to face new challenges, such as the reduction of environmental impact, the improvement of animal-derived food quality and safety, the reduction of antibiotics, and the increase in efficiency. One of the strategies that could be adopted is Precision Livestock Farming (PLF), recognized as the most sustainable tool to improve farm sustainability. It can be defined as “the continuous, automated, and real-time monitoring of production, reproduction, health, and welfare through the application of advanced information and communication technologies (ICT)”. In this new farm concept, animals, environment, machinery, and processes become “information objects” to enhance data; farm management and animals are defined as CITD systems: they are Complex, Individually different, Time- variant, and Dynamic. Several PLF technologies have been recently applied to buffalo species, improving some critical points of the farm, such as milking, nutrition, reproduction, and management. This short review reports some experiences carried out in buffalo species.
Evaluation of genetic trend in milk production of buffalo cattle in Colombia

Published: January 2025

Assessing genetic trends in livestock is pivotal for comprehending how populations have evolved over time. This provides valuable insights into the direction and magnitude of genetic change, which is crucial for evaluating the outcomes of selection processes within herds. This study aimed to evaluate the genetic trend in milk production of buffalo cattle in Colombia. The study used the productive database of purebred Murrah Buffaloes recorded by the Colombian Buffalo Breeders Association (ACB), encompassing productive and genealogical records of 774 animals born between 2008 and 2017. A GAMS model was applied to assess genetic values, considering the birth year of the animal. The mean genetic value in the evaluated population was 45.42 ± 85.31 kg, with minimum and maximum values of -160.54 and 377.34 kg, respectively. When analyzing genetic values by year, the highest value was observed in 2014 (56.26 kg), while the lowest was recorded in 2017 (32.65 kg). The GAMS model estimated an intercept of 45.42 kg (p<0.001), with an explained variance of 63%. The genetic trend showed stable values from 2008 to 2011, but from that point onwards, a decline was evident, becoming more pronounced from 2014 onward. The results indicate a decrease in genetic values for the milk production trait in the evaluated population. This decrease is attributed to the limited use of high-genetic-value sires in biotechnological programs and low selection intensity. To achieve favorable genetic progress, it is important to conduct selection processes based on genetic evaluations undertaken in the country, increase selection intensity by the widespread use of sires with positive genetic values, and restrict the use of animals with negative genetic values. In 2015, Agudelo et al. also estimated similar genetic trends without significant increases in the genetic trend for milk production. Strategies should be developed to allow the introduction of new animals or genetic lines through the purchase or exchange of sires with positive genetic values. Those strategies can enhance genetic diversity and provide new opportunities for improvement by expanding the range of selection possibilities. Additionally, the use of biotechnological tools such as artificial insemination and embryo transfer should be promoted to expedite the dissemination of genetically superior animals.

The buffalo herds in Venezuela are characterized by a high phenotypic polymorphism, showing high diversity among individuals. The leading cause is the great mixture of breeds involved in the crossbreeding programs, such as Murrah, Mediterranean, Nili Ravi, Jafarabadi, and Carabao. Morphometric measurements assist in racial characterization by comparing genetic groups (within and between) and establishing the relationship between the conformation and functional traits, eliminating undesirable characters, and helping in the selection process for the identification of morphologically superior animals. The morphometry study consists of the search for a functional animal. These traits also contribute to the selection process in identifying the morphologically superior animals and eliminating the unwanted characters. This phenotypic characterization of buffaloes comprised quantitative and qualitative traits of 157 female buffaloes aged 24 to 48 months and 21 males aged 18 to 36 months. There were measurements on 24 traits, 18 quantitative (cm) variables considered as morphometric: (i) wither height (HW), (ii) rump length (RL), (iii) rump angle (RA), (iv) hip length (HL), (v) rump width (RW), (vi) hip width (WH), (vii) heel depth (HD), (viii) shoulder width (SW), (ix) chest depth (CD), (x) heart girth (HG), (xi) body length (BL), (xii) tail length (TL) and six qualitative traits, a) loin strength (LS), b) hock angle (HA), c) foot angle (FA) and d) dairy form (DF); and only for females (xiii) fore udder attachment (FUA), (xiv) rear udder height (RUH), (xv) rear udder width (UW), (xvi) udder depth (UD), (xvii) udder cleft (UC), (xviii) teat length (LT) and e) Nipple direction (ND) and f) Nipple position (NP). The data were subjected to descriptive and ANOVA analysis for breed predominance and sex. No difference was found between the predominant breed (p>0.05) means ± SE were: for HW (132.41±0.82), RL (44.86±0.67), RA (10.68±1.45), HL (56.26±0.98), RW (26.76±0.80), WH (50.5±0.97), HD (2.8±0.10), HG (201.42±2.60), TL (88.09±1.50); except SW 41.69±0.73 vs 44.31±0.70 (p<0.002); CD 72.68±1.45 vs 76.03±1.40 (p< 0.01) and BL 136.7±2.06 vs 142.02±1.98 cm (p<0.04) for Mediterranean vs Murrah predominance, respectively. The sex affects only the variables for rump RL, HL, RW, 45.5±0.42 vs. 42.7±1.05 (p<0.01), 59.42±0.59 vs. 53.42±1.49 (p<0.001), and 28.99±0.48 vs. 22.97±1.20 cm, (p<0.001), for females and males, respectively. On all qualitative measurements, there were no significant differences. The results could suggest that the body morphometric traits could be incorporated in designing selection programs for buffalo breeding in Venezuela. This information would include the genetic evaluation using the BLUP methodology and the morphological characterization of the breeds present in Venezuela, constituting a starting point in the genetic programs.
Influence of type traits on stayability in the Ital- ian Mediterranean buffalo

Published: January 2025

The selection schemes adopted over the past 20 years for the Italian Mediterranean Buffalo, together with the marked improvement in farm management techniques and the systematic application of AI in an increasing number of subjects, have resulted in a sharp improvement in the quantities of milk produced per lactation. Experiences from dairy cows suggest that such an improvement could reduce the average productive life span of breeding females and, therefore, their longevity. Animal longevity has a multifactorial etiology where physiology and morphology, in close correlation with each other, cross their effects to enable animals to continue to produce efficiently on the farm. In the past, the selection of the Italian Mediterranean buffalo has mainly focused on increasing milk production, which has had an unfavorable impact on the average farm life of the IMB. This trend needs to be reversed as this inevitably leads to an increase in production costs due to the increase in the replacement rate. There are many ways to assess longevity, both quantitatively, such as age at culling and parity at culling, and qualitatively, such as in the case of stayability, where it is evaluated as a binary variable where 1 and 0 indicate the ability to stay or be culled at a given time, respectively. In a recent study, we evaluated the genetic aspects of stayability in IMB, and the results suggest the possibility of using it in the selection process. This study aimed to correlate stayability with the linear type traits measured by the ANASB for IMB and with the merit score values for body conformation, limbs, feet, and udder. Data from 276.415 buffalo cows registered in the ANASB studbook starting from 1989 were extracted and merged with the official milk test-day recording datasets from the Italian Breeder’s Association (AIA). The stayability from parity one up to 10 was assessed assigning a value of 1 if a calving date was present or 0 otherwise. Investigating the relationship between some morphological traits and longevity would give them the proper em-phasis in formulating genetic indexes or creating specific aggregated indexes to make the selection process more efficient.

Published: January 2025

In the dynamic landscape of organizational operations, effective communication is a cornerstone for fostering stakeholder trust and maintaining a positive reputation. However, communication barriers—ranging from cultural and linguistic differences to misinformation and technological disparities—can impede the seamless flow of information, jeopardizing an organization’s reputation. This study explores the strategic integration of media and public relations (PR) as a unified approach to overcome these barriers and enhance organizational reputation management. By leveraging media platforms for widespread dissemination and utilizing PR strategies to foster authentic stakeholder engagement, organizations can create cohesive narratives that align with their values and objectives. The paper examines key components of this integration, including the role of digital transformation in media practices, the importance of cultural sensitivity in messaging, and the application of crisis communication strategies. It highlights case studies where the synergistic use of media and PR effectively mitigated communication challenges and restored organizational credibility during crises. Furthermore, the study investigates how emerging technologies such as artificial intelligence (AI) and data analytics are reshaping media and PR practices, enabling real-time monitoring and adaptive communication strategies. Findings reveal that organizations adopting an integrated media-PR framework achieve higher stakeholder trust, improved message clarity, and resilience in reputation management. The study concludes with recommendations for organizations to invest in cross-functional teams, continuous training, and technology adoption to enhance their communication strategies. By addressing communication barriers proactively, organizations can strengthen their reputational capital, ensuring long-term success in a competitive and rapidly evolving global environment.

Authors: Jinyoung Hwang
Published: January 2025

This cross-national, multi-case study dissertation utilizes mixed methods to examine innovation models underlying digital transformations within European social service agencies. The research draws on data from secondary sources, semi-structured interviews and focus groups with over 100 participants from human services departments across 10 European countries representing contrasting domain contexts. Initial analysis of secondary data on recent technology deployments categorizes country and domain-level patterns in adoption rates and tools prioritized based on a conceptual framework integrating technology acceptance, e-government, and public administration scholarship. Countries and domains are clustered based on common innovation trajectories reflected through automated indicators like number of new digital tools introduced annually and service functions shifted online. Further qualitative insights into transformation motivators, mechanisms and outcomes are garnered through 30 in-depth interviews with leaders from agencies representing varied adoption levels. Eight multi-stakeholder focus groups across four countries delve deeper into digitization experiences across domains to highlight change catalysts, capabilities and barriers. A comparative analysis framework maps domains and countries to contrasting innovation models based on internal and external change stimuli which shape pathways for overcoming common hurdles and progressing technology assimilation. Implications are derived for policymakers and practitioners seeking to advance context-appropriate, sustainable digitization of European social safety nets.

Published: January 2025

Introduction: Acute idiopathic scrotal edema (AISE) is a rare, self-limiting condition of uncertain etiology, predominantly affecting children. It is characterized by sudden scrotal swelling and erythema without involvement of the testes or paratesticular structures. While benign, it can mimic more severe conditions like testicular torsion, requiring careful differentiation to avoid unnecessary surgical interventions.

Case Report: We report the case of an 8-year-old boy in Saudi Arabia who presented with acute onset bilateral scrotal swelling, mild erythema, and tenderness, predominantly on the right side. There were no associated fever, trauma, or urinary symptoms. A similar episode two weeks earlier was resolved without medical intervention. Examination revealed generalized scrotal swelling with skin thickening, palpable testicles with normal position and size, and intact cremasteric reflexes. Laboratory results were unremarkable except for mild leukocytosis. Doppler ultrasound showed preserved vascularity of both testicles with characteristic edematous scrotal wall thickening and the “fountain sign,” confirming the diagnosis of AISE. Management and outcome: The patient was managed conservatively with non-steroidal anti-inflammatory drugs (NSAIDs) and intravenous (IV) ceftazidime. The symptoms resolved completely within 48 hours, and he was discharged in good condition with a short course of oral antibiotics. A two-week follow-up showed no recurrence or residual symptoms.

Conclusion: This case underscores the importance of recognizing AISE in pediatric acute scrotum presentations to avoid unnecessary surgery. Clinical evaluation and Doppler ultrasound, highlighting the “fountain sign,” are pivotal for diagnosis. Conservative treatment ensures a rapid and favorable outcome, as demonstrated in this case.

Published: January 2025

Aims: Pancreatic cancer is a major disease to fatalities worldwide. To understand its molecular mechanisms is crucial for improving diagnosis and treatment. We aim to identify key biomarkers and biological pathways associated with pancreatic adenocarcinoma using RNA sequencing data from The Cancer Genome Atlas (TCGA). To analyze differentially expressed genes in pancreatic cancer, performed enrichment analysis to uncover crucial biological processes and cellular components, evaluated the impact of identified genes on patient survival and prognosis.

Methods: We examined RNA sequencing data from TCGA to identify differentially expressed genes (DEGs), crucial biological processes, and cellular components associated with pancreatic cancer. Enrichment analysis was conducted to pinpoint significant genes involved in various pathways, and survival analysis was performed to assess the impact of these genes on patient outcomes.

Results: Our analysis identified several significant genes linked to pancreatic cancer, including EDN1, KDM1A, KDM5D, KDM6A, NLGN4Y, RASGRP, SQLE, TMSB4Y, TNF, USP9Y, 1UTY, and ZRSR2. Notably, Ras guanyl nucleotide-releasing protein (RASGRP), tumor necrosis factor (TNF), and ZRSR2 showed lower expression levels than normal tissues, while KDM1A and KDM3A were significantly overexpressed, correlating with poor prognostic outcomes. Survival analysis indicated that EDN1, KDM1A, RASGRP, and squalene epoxidase (SQLE) are associated with mortality risk or disease recurrence.

Conclusion: Our findings highlight key biomarkers and pathways involved in pancreatic cancer, emphasizing the potential of KDM1A and KDM3A as therapeutic targets. By identifying these biomarkers, we aim to contribute to developing targeted therapies that could enhance patient prognoses and improve treatment strategies for pancreatic cancer.
A shear effect in a bending non-standard I-beam under uniformly distributed load
Authors: Magnucka-Blandzi Ewa Magdalena , Magnucki Krzysztof
Published: January 2025

The paper is devoted to the analytical study of the bending problem of a simply supported or clamped non-standard I-beam under a uniformly distributed load. The cross-sectional shape of this beam, as a three-part structure, is analytically described. The purpose of this research is to present a detailed analytical model of this beam, considering the shear effect and its influence on the beam's deflection. This model is formulated according to linear elastic theory, and the deformation of a planar cross-section after the bending of this beam due to the shear effect is determined. Based on the principle of stationary potential energy, two differential equations of equilibrium are obtained. These equations are analytically solved, and the dimensionless shear effect function and the relative deflection of this beam are derived. Consequently, the maximum dimensionless relative deflection and the dimensionless coefficient of the shear effect are determined. Exemplary calculations are carried out for three selected non-standard I-beams of different lengths, demonstrating a significant influence of the shear effect on the deflections of short beams, especially clamped beams.

Climate change is felt very influential in the wet tropics as in Indonesia. The impacts of climate change that felt much were floods and landslides during the rainy season and drought during the dry season. The occurrence of landslides in mountain slopes is mostly caused by soil, topography, geology, hydrology and climate. The purpose of the study is to determine the areas prone to landslides in the Samin River Basin area on the western slopes of Lawu mountain, and management efforts through mitigation areas prone to landslides in order to anticipate the impacts of climate change. The research method is overlapping topography map, land map, land use map, climate map, geological map and earth map as base map. Besides, field survey was conducted to observe the morphology of soil landslide events and in-depth interviews. The results showed that the research area of 6,797.06 ha consisted of very prone to landslides (73.64%), prone to landslide 26.25%, and slightly prone to landslide 0.11%. The most influential factors in the landslide are topography, rainfall and land cover. Landslide type that occurs mostly is slump landslide, followed by rockfall and landslide. Soil sensitive type of landslide are Andosol and Latosol. Land use that is very prone to landslides is the land tha are used for vegetable cultivation and land conversion functions for road construction. Management efforts to mitigate landslides among others are landslide reforestation potential landslides, and land use systems with an intercropping system of annual crops with agro forestry on cultivated land.

Published: January 2025

In this study, the assessment of the outdoor Background Radiation levels in Lafia Metropolis, Nasarawa State, Nigeria has been conducted. An in-situ measurement of outdoor background exposure rate count per minute for 20 locations was done using a well calibrated portable halogen-quenched Geiger Muller (GM) detector (Inspector alert Nuclear radiation monitor SN:3544) at an elevation of 1.0m above ground level with a geographical positioning system(GPS) for geographical location. Using an established radiological relations, the radiological health hazards and radiation effective doses to different body organs were evaluated using the measured outdoor background exposure rates. The values obtained were compared with recommended permissible limits to ascertain the radiological hazard status of the environment. The mean values of the outdoor background exposure levels (0.021 mRh-1), absorbed dose rates (184.875 nGyh-1) and excess lifetime cancer risk (0.794×10-3) are higher than their recommended safe limits of 0.013 mRh-1, 84.0 nGyh-1, 0.29×10-3respectively as recommended by UNSCEAR and ICRP. The mean annual effective dose equivalent (AEDE) (0.227 mSvy-1) is below recommended permissible limits of 1.00 mSvy-1 for general public exposure and also the effective doses to different body organs are all below the recommended limits of 1.0 mSvy-1. Generally, the study shows that Lafia Metroplis is relatively safe radiologically with little contamination which could be attributed to the geological formation and partly due to human activity in the area. However, the contamination will not pose any immediate radiological health effect on resident of the area but there is tendency for long –term health hazards in the future such as cancer due to doses accumulated.

Kazakhstan ranks second in the world in terms of natural uranium reserves and dominates in its production. Hydrometallurgical processing of uranium-containing raw materials generate a large amount of liquid technogenic waste, which are waste solutions requiring disposal. Sorption methods fall under the group of the most effective methods for purifying liquids from contamination with radionuclides. Synthetic sorbents are expensive, and the natural ones have low sorption capacity, which represents a disadvantage in their usage. Obtaining modified ion-exchange materials based on their combination is an urgent problem faced by the nuclear industry.

The paper discusses a modifying method applicable to natural coal and mineral raw materials in Kazakhstan. The Koksu deposit shungite was selected for the research. Source raw materials were subjected to flotation. The paper introduces data obtained from physical and chemical studies of the source raw materials and the derived concentrate. A modified sorbent was derived based on the concentrate, and its sorption capacity was studied.

Malaria was declared an emergency in Nigeria and strategies for the control of Malaria in Nigeria were adopted to reduce its prevalence to a level at which the disease will no longer constitute public health problems. In this work, we presented a deterministic (Ross–Macdonald model susceptible, expose/ infected, infectious and recovered) model incorporating the method of control adopted by national Malaria and leprosy control program. We established the disease free and the endemic equilibrium states and carried out the stability analysis of the disease. Free and the equilibrium state. We also carried out numerical simulation of the model to have an insight into the dynamics of the model. We found out that the disease free equilibrium state is stable. The feedback dynamics from mosquito to human and back to mosquito involve considerable time due to the incubation periods of the parasites. In this paper, taking explicit account of the incubation periods of parasites within the human and the mosquito, we first propose a Ross–Macdonald model. The Jacobiant results showed that it would be very difficult to completely eradicate Malaria from Nigeria using the method adopted by national Malaria and leprosy control program.

Electrocardiogram (ECG) examination is of great importance in medical diagnosis of the cardiac disease, but wrong interpretation due to noise interference in the signal could be dangerous as this may lead to wrong diagnoses of patient’s heart condition. De-noising helps to reduce the noise level for a better interpretation of the signals. In this study, an analysis of Savitzky-Golay (S-G) filter for ECG de-noising using Daubechies wavelets has been carried out using MATLAB version 2015a. Noisy ECG signals downloaded from physionet.org under MIT-BIH arrhythmia database was de-noised using S-G filter of polynomial order 9 to data frames of length 21 displayed in both time and frequency domains while a quantitative evaluation was carried out to check the performance of the filter under signal-to-noise ratio (SNR), mean square error (MSE) and signal-to-interference ratio (SIR). Results show that de-noising using S-G filter for SNR, MSE, and SIR gives an average value of 32.78dB, 0.0001 and 1852.358dB respectively. This implies that the S-G filter helps eliminates the background noise as well as maintaining a good fit for our data, and also do not allows co-channel interference from other radio transmitters, which makes it an excellent filter for ECG signal de-noising. Hospitals management and cardiac health centers most understand the importance of these parameters in the selection of de-noising filters for good quality ECG in diagnosis and treatment of cardiac patients.

Geophysical investigation has been carried using Vertical Electrical Sounding (VES) at site in Kukwaba District, Abuja to examine the geophysical parameters that can be used to evaluate the structural competence of the subsurface for foundation. The Schlumberger array configuration was used for the Acquisition of the data. The electrical resistivity data were processed and interpreted using IP12win software package and Surfer 12. A total of 15 VES point was carried out with a maximum current electrode spacing (AB/2) of 100m. The results revealed maximum of five layer, the topsoil, the laterite, weathered layer, fractured basement and fresh basement. The resistivity value of the topsoil ranges between 85.1Ωm to 2416Ωm which is typical clay, clayed, sand, sandy clay and laterite with laterite being the most competent and clay being lest competent. From Geoelectric section, it is observed that the top layer resistivity of VES point 3, 11 and 15 with resistivity value less than 100Ωm are characterized by clay with high moisture content and therefore not competent, while VES point 12 and 14 are lateritic in nature; thus very competent and good for high rising building, while VES point 1, 2, 4, 5, 6, 7, 8, 9, 10, and 13 are moderately competent and can with stand small engineering construction.

We proposed a so-called Beta Kumaraswamy Burr Type X distribution which gives the extension of the Kumaraswamy-G class of family distribution. Some properties of this proposed model were provided, like the expansion of densities and quantile function. We considered the Bayes and maximum likelihood methods to estimate the parameters and also simulate the model parameters to validate the methods based on different set of true values. Some real data sets were employed to show the usefulness and flexibility of the model which serves as generalization to many sub-models in the fields of engineering, medical, survival and reliability analysis.

This study explores the potency of Technologically Enhanced Jigsaw Method (TEJM) in breaking the barriers to meaningful learning of biology concepts. The explanatory sequential design was employed. A total of 102 secondary school (II) students from two randomly selected schools in Lagos State Education District V participated in the study. The Nervous Coordination Achievement Test (NCAT) which had a reliability coefficient of 0.76 was the instrument used to collect the quantitative data. Treatment lasted Four weeks after the conduct of the pretest, the experimental group was taught using Technologically Enhanced Jigsaw Method and the control group was taught using the conventional lecture method. One-way ANCOVA was employed to analyse the data. The students in the experimental group taught using Technologically Enhanced Jigsaw Method performed significantly better than their control group counterparts. Also, the students had a positive view towards the effectiveness of the Technologically Enhanced Jigsaw Method. Within the limitations of the study, we concluded that Technologically Enhanced Jigsaw Method is capable of promoting meaningful learning in biology. Based on the findings of this study, we recommended that the teachers should employ Technologically Enhanced Jigsaw Method for promoting meaningful learning of biology in contemporary and technology-driven societies. Implications of the study were highlighted.

In this study, photon shielding properties of standard concrete (SC), concrete doped ferro boron (CFB), concrete doped boron carbide (CBC), concrete doped galena (CG) and concrete doped ilmenite (CI) were investigated. A theoretical study of the mass attenuation coefficients (MAC) of standard concrete and concrete doped materials were determined by a winXCOM computer program. The radiation shielding parameters such as mass attenuation coefficient (MAC), linear attenuation coefficient (LAC), half value layer (HVL), tenth value layer (TVL) and mean free path (MFP) of the mixture were calculated in the photon energy range of 0.01-10.0 MeV. The MAC values showed a sharp decline as the energy increases to a certain extent and reduces smoothly after that for all the materials investigated. The maximum (minimum) MAC values were 10.88 (0.023), 34.90 (0.024), 15.80 (0.022), 39. 20 (0.027), and 34.50 (0.023) cm2/g for SC, CFB, CBC, CG and CI respectively. The maximum value of LAC was obtained at 0.010 MeV with value of 44.10, 81.22, 20.40, 16.90 and 99.20 cm-1 for SC, CFB, CBC, CG and CI respectively. The MAC and LAC value are in the order of CG > CI> CFB > SC > CBC. The HVL, TVL, and MFP show similar pattern and are in the order of CBC > CI > SC > CFB > CG. The results indicate that adding galena compound into concrete mixture can significantly enhance the photon shielding capability.
