Authors: Mustafa Ahmed W. , Saied Adil A. Mohamed , Sadiq Hajer A.
Published: June 2022

The effect of a semi-circular cylinders in a two dimensional channel on heat transfer byforced convection from two heat sources with a constant temperature has been studiednumerically. Each channel contains two heat sources; one on the upper surface of thechannel and the other on the lower surface of the channel. There is semi-circular cylinderunder the source in upper surface and there is semi-circular cylinder above the source inlower surface. The location of the second heat source with its semi-cylinder has beenchanged and keeps the first source with its semi- cylinder at the same location. The flowand temperature field are studied numerically with different values of Reynolds numbersand for different spacing between the centers of the semi-cylinders. The laminar flow fieldis analyzed numerically by solving the steady forms of the two-dimensional incompressibleNavier- Stokes and energy equations. The Cartesian velocity components and pressure on acollocated (non-staggered) grid are used as dependent variables in the momentumequations, which discretized by finite volume method, body fitted coordinates are used torepresent the complex channel geometry accurately, and grid generation technique based onelliptic partial differential equations is employed. SIMPLE algorithm is used to adjust thevelocity field to satisfy the conservation of mass. The range of Reynolds number is (Re=100 – 800) and the range of the spacing between the semi-cylinders is(1-4) and the Prandtlnumber is 0.7.The results showed that increasing the spacing between the semi-cylinders increases theaverage of Nusselt number of the first heat source for all Reynolds numbers. As well as theresults show that the best case among the cases studied to enhance the heat transfer is whenthe second heat source and its semi-cylinder located on at the distance (S=1.5) from thefirst half of the cylinder and the Reynolds number is greater than (Re ≥ 400) because of theseparation behind of the first semi-cylinder where it works to reduce the area of sectionflow, and this is leading to increase the speed and thus increases the rate of heat transfer. Acomparison of numerical results agrees well with published results.

Improved FHT Algorithms for Fast Computation of the Discrete Hartley Transform
Authors: Hamood Mounir Taha
Published: June 2022

In this paper, by using the symmetrical properties of the discrete Hartley transform (DHT), an improved radix-2 fast Hartley transform (FHT) algorithm with arithmetic complexity comparable to that of the real-valued fast Fourier transform (RFFT) is developed. It has a simple and regular butterfly structure and possesses the in-place computation property. Furthermore, using the same principles, the development can be extended to more efficient radix-based FHT algorithms. An example for the improved radix-4 FHT algorithm is given to show the validity of the presented method. The arithmetic complexity for the new algorithms are computed and then compared with the existing FHT algorithms. The results of these comparisons have shown that the developed algorithms reduce the number of multiplications and additions considerably.

Authors: Ali Mohamed Burhan
Published: June 2022

In this research, the ability of effective microorganisms (EM) to remove nitrate from groundwater had been studied. Many samples were taken and tested from several wells in Tikrit University. The tests showed that the samples of groundwater contained a few nitrate concentrations (less than 1 mg/l) so that the wastewater was a synthetic solution by adding potassium nitrate (KNO3) to the groundwater as a nitrate source within the range of (50–150) mg/l. the ratios of EM were used in the experiments ranged between (1:250) to (1:5000). While the hydraulic retention times 24 and 48 were used in the experiments. The result showed that the removal efficiency of nitrate was increased by increasing the ratio of EM in the processing unit and the maximum nitrate removal was 82% when the nitrate concentration and EM ratio were 150 mg/l and (1:250) respectively and HRT was 48 hr.

Published: June 2022

In steam power plants, and high pressure high temperature water flow, phase change takes place resulting in bubbly flow. Such flow causes vibration and noise in the conduits. The present study emphasized on cavitations during a dual phase flow (water- vapor) with a variation of velocities at different conditions in converge-divergence nozzle. The investigation was carried out experimentally and numerically, by CFD simulation. A transparent material is used of PMMA in order to visualize the various regions of the flow. Furthermore, the effect of flow velocities on vibration and noise was evolved in the experimental measurements. The CFD simulation model of this problem is defining a dual compressible viscous flow with k-epsilon model for the turbulence modeling. The analyses of the simulation results and the experimental observation have been seen to be comparatively conscionable in the cavitation zone and the estimation of the throat pressure cavitations during a dual phase flow with a variation of mass transfer conditions. A model were combined with a linear viscous turbulent model for the mixed fluids in the computational fluid dynamics software. A CFD Code with modified user intervention is used to simulate steady cavitation. Some of the models were also tested using a three dimensional -CFD code in configurations of cavitation on three-dimensional a converge-diverge sections. The pressure distributions and volume fractions of vapor at different cavitation numbers were simulated, which agreed well with experimental data.

Authors: Nua’man Muhammed Muthanna
Published: June 2022

Water quality degradation in the Tigris River would occur in the last two decades since pollutant loads from agriculture drainages, municipal wastewaters, and industrial wastewaters are not envisaged to be handled effectively. This will face the problems of water quality status which is used for multiple purposes, and drinking is one of these. This study used the Bhargava Water Quality Index (WQI) method as a tool to assess the water quality status of Tigris River as a source of raw water for water treatment plants within Salah-Alddin Province. For this purpose, six sectors along the mainstream were chosen to take water samples from January 2010 until December 2010. The study had shown that the stream WQI lies between 2nd class (good -84.31) to 5th class (poor – 39.73). Decline of WQI values had appeared in all sectors in (January and February 2010) and improved after February 2010. The median values of WQI for Balad sector were the lowest in comparison with other sectors due to the effect of human, animal and agricultural activities, whereas, the median values of WQI for Al-dour sector was the highest because the strong hydraulic mix in addition to high water velocity.

Mechanical Properties of Fiberous Recycled Aggregate Concrete
Authors: Hameed Sarab A.
Published: June 2022

Conservation of natural resources and rapid urbanization has prompted growing demand for natural aggregate by construction industry. This demand is compounded by considerable decline in the availability of good quality natural aggregate and enormous increase in quantities of demolished concrete. This report presents a study of mechanical properties of concrete made by using the demolished concrete as coarse aggregate in addition to steel fibers.. In the concrete mixes the ratios of concrete aggregate range from 0% to 100% with the increment of 25% the ratio of steel fiber was 6% of whole mix volume. Three concrete mixes have been prepared with proportion of 1:2:4, the water cement ratio was 0.5. The essential mix was control mix without steel fiber for comparison, the other mixes with or without steel fibers with different proportion of recycle concrete aggregate. The mixes were casted in standard specimens, cylinders and cubes and tested under static loading The specimens were tested for compression strength and splitting tensile strength. This research shows that increasing recycle concrete aggregate will decrease the compressive strength and splitting tensile strength but adding steel fibers will increase these strengths. The recycled concrete aggregate with steel fiber are found to make a good quality concrete therefore recycle concrete aggregate can be used successfully for structural concrete instead of natural aggregate .

The Temperature Dependence of the Linear-in-Density Thermal Conductivity Coefficient Arising from the Lennard-Jones (12-6) Potential
Authors: Laesecke Arno
Published: June 2022

Results of the modified Rainwater-Friend theory for the initial density dependence of the thermal conductivity arising from the Lennard-Jones (12-6) potential in the range of reduced temperature 0.5 ≤ T*≤ 100 have been correlated. Informed by theory, a collection of 41 functional temperature terms was narrowed to the eight most significant terms by structural optimization. The new formulation is the first that extrapolates correctly beyond the data range to reduced temperatures of 0.01 and 150. It contributes significantly to an improved understanding of thermal conductivities of gases at low densities and low temperatures where measurements are rare.

Published: June 2022

Classical molecular dynamics (MD) simulations represent a very popular and powerful tool for materials modeling and design. The predictive power of MD hinges on the ability of the interatomic potential to capture the underlying physics and chemistry. There have been decades of seminal work on developing interatomic potentials albeit with a focus predominantly on capturing the properties of bulk materials. Such physics-based models, while extensively deployed for predicting dynamics and properties of nanoscale systems over the past two decades, tend to perform poorly in predicting nanoscale potential energy surface when compared to high-fidelity first-principles calculations. These limitations stem from the lack of flexibility in such models, which rely on a pre-defined functional form. Machine learning models and approaches have emerged as a viable alternative to capture the diverse size-dependent cluster geometries, nanoscale dynamics and the complex nanoscale potential energy surfaces (PES), without sacrificing the bulk properties. Here, we introduce an ML workflow that combines transfer and active learning strategies to develop high-dimensional neural networks (NN) for capturing cluster and bulk properties for several different transition metals with applications in catalysis, microelectronics, and energy storage to name a few. Our NN first learns the bulk PES from the high-quality physics-based models in literature and subsequently augments this learning via retraining with a higher fidelity first-principles training dataset to concurrently capture both the nanoscale and bulk PES. Our workflow departs from status-quo in its ability to learn from a sparsely sampled dataset that nonetheless covers a diverse range of cluster configurations from near-equilibrium to highly non-equilibrium as well as learning strategies that iteratively improves the fingerprinting depending on model fidelity. All the developed models are rigorously tested against an extensive first-principles dataset of energies and forces of cluster configurations as well as several properties of bulk configurations for 10 different transition metals. Our approach is material agnostic and provides a methodology to transfer and build upon the learnings from decades of seminal work in molecular simulations on to a new generation of ML trained potentials to accelerate materials discovery and design.

The cation exchanger Letm1, circadian rhythms, and NAD(H) levels interconnect in diurnal zebrafish
Authors: Dao Pauline , Hajny Stefan , Mekis Ronald , Orel Lukas , Dinhopl Nora , Tessmar-Raible Kristin , Nowikovsky Karin
Published: June 2022

Mitochondria are fundamental for life and require balanced ion exchange to maintain proper functioning. The mitochondrial cation exchanger LETM1 sparks interest because of its pathophysiological role in seizures in the Wolf Hirschhorn Syndrome (WHS). Despite observation of sleep disorganization in epileptic WHS patients, and growing studies linking mitochondria and epilepsy to circadian rhythms, LETM1 has not been studied from the chronobiological perspective. Here we established a viable letm1 knock-out, using the diurnal vertebrate Danio rerio to study the metabolic and chronobiological consequences of letm1 deficiency. We report diurnal rhythms of Letm1 protein levels in wild-type fish. We show that mitochondrial nucleotide metabolism is deregulated in letm1−/− mutant fish, the rate-limiting enzyme of NAD+ production is up-regulated, while NAD+ and NADH pools are reduced. These changes were associated with increased expression amplitude of circadian core clock genes in letm1−/− compared with wild-type under light/dark conditions, suggesting decreased NAD(H) levels as a possible mechanism for circadian system perturbation in Letm1 deficiency. Replenishing NAD pool may ameliorate WHS-associated sleep and neurological disorders.
An Examination of Community Attitudes towards Individuals with Mental Illness who have Criminally Offended compared to Individuals with Mental Illness and Individuals who have Criminally Offended
Authors:   , Sutton Heath
Published: June 2022

Negative community attitudes can have a significant impact upon recovery, reintegration, and desistance of individuals with mental illness and those who have criminally offended. Despite sharing characteristics with individuals with mental illness (IMI) and individuals who have criminally offended (ICO) that are independently stigmatising, no study has investigated whether individuals with mental illness who have criminally offended (IMICO) experience more, less, or similar levels of stigma as IMI and ICO. This research aimed to compare and examine community attitudes towards these three groups. An online experiment was conducted with an Aotearoa New Zealand adult community sample, with participants completing a survey and being randomly assigned to answer questions about their perceptions and affective, cognitive, and behavioural attitudes towards either IMI, ICO, or IMICO.

Familiarity with mental illness and criminal offending were included as independent variables, whilst media scepticism and empathy were also measured as key demographic influences. Results indicated that attitudes were significantly more positive towards IMI, with no significant difference between ICO and IMICO across attitudinal domains. The influence of familiarity was limited to behavioural attitudes only, with an interaction effect for mental illness and a main effect for criminal offending; media scepticism was partially correlated with attitudes towards IMI (perceptions/affective domains) and IMICO (cognitive domain); whilst empathy, with the exception of personal distress, was consistently related to more positive attitudes across groups. These findings extend previous research and theory regarding how IMI, ICO, and IMICO are viewed by the community, with implications and directions for future research discussed.
Spanish University Students' Use of Authentic Videos and their Motives for Engaging in this Informal Activity: A Study with EFL Learners of Different Proficiency Levels
Authors: Sinyashina Ekaterina
Published: June 2022

This paper examines informal learning practices of Spanish university EFL learners of different proficiency levels with authentic videos in English and the reasons for engaging in this activity. For this purpose, one hundred and fifty-six students of mixed proficiency levels completed a questionnaire. The general percentages revealed that the majority of them are exposed to authentic videos with very high or considerably high frequency, they normally undertake this activity alone using their computers, laptops or mobile phones, and they tend to watch authentic videos with captions/subtitles either in English or in Spanish. The Internet and streaming services were identified as the two most commonly used sources. Furthermore, many of the respondents enjoy this activity and find it particularly useful for developing their listening skills and lexis. A statistical analysis of the results revealed a clear impact of the proficiency level on the frequency of exposure, the use of subtitles/captions, the sources and reasons for doing this informal activity.
W.F. Deacon and his Revision of Romanticism in Warreniana through Literary Parody and Advertising Campaigns to Promote Blacking
Authors: Ramos Ramos María Rocío
Published: June 2022

This study aims to reassess William Frederick Deacon (1799-1845) and his work Warreniana (1824) by demonstrating that although it is a work of textual parody, its apparent triviality conceals a sophisticated exercise in literary criticism, constituting a valuable contemporary commentary on Romanticism. The collection presents a witty and sophisticated exercise in criticism of the literature and style of its period, being composed of texts attributed to a selection of Romantic authors supposedly promoting a very trivial product: Warren’s blacking (shoe polish). Deacon thus acts as another Romantic critic, albeit a more original and unconventional one. Due to space constraints, this paper will focus only on the parody of the poetic style of British romantic authors. The parody of their journal style will be analysed in another article.
Hilary Mantel’s Re-appropriation of Whig Historiography: A Reading of The Wolf Hall Trilogy in the Context of Brexit
Authors: Prieto Arranz José I.
Published: June 2022

This article analyses Hilary Mantel’s critically-acclaimed Tudor novel series (Wolf Hall, 2009; Bring Up the Bodies, 2012; The Mirror & the Light, 2020) in the context of Brexit. Even though Mantel has dismissed any possible analogy between the Reformation and Brexit, this research builds on the hypothesis that the past and the present interact in historical fiction, a genre that has contributed to both feeding and questioning the myths upon which nations are constructed. More specifically, I focus on the trilogy’s protagonist, Thomas Cromwell, to argue that he is presented as the architect of what Whig historiography has understood as the pillars of Englishness (and, by extension, Britishness), often evoked in the discursive context surrounding Brexit. However, although the narrative’s portrayal of Cromwell undoubtedly fosters the reader’s sympathy with the character, a deeper analysis of Mantel’s characterisation and narrative techniques —and, more specifically, Cromwell’s status as a flawed human being presented through the lens of what turns out to be an unreliable narrator— suggests that Mantel’s portrayal of Cromwell cannot be reduced to a simple vindication of the Whiggish notion of Englishness, subtly questioning instead the myths upon which the latter is built.

Introduction: As young healthcare professionals (HCPs) enter the workforce, they find challenges adapting as academic training and workplace settings often do not mirror each other. Mentorship is a possible solution to help bridge this transition. The aim of this study was to gather information from HCPs with regards to their views towards mentorship as a strategy to help in the transition of newly qualified HCPs from study to work. Methods: Two 3-hour interactive workshops entitled “Bridging the Study-Work Chasm” were organised, and participants were invited to complete a survey voluntarily after the workshop. The survey comprised questions regarding the benefits of mentorship, qualification of mentors, time commitment for mentoring, elements of an effective mentorship programme, and barriers to its effectiveness. The anonymised responses were analysed descriptively. Results: Fifty-two out of 62 participants from various healthcare backgrounds completed the survey. 96.2% of respondents felt a study-work chasm exists in the healthcare workplace with 90.4% indicating that a mentorship programme would help to bridge the chasm. More than 70% of participants agreed or strongly agreed that mentoring would boost confidence, reduce anxiety, and aid in study-work transition. It was identified that to produce a more effective mentorship programme, time commitment, training, and proper organisation of the programme would be necessary. Conclusion: It was perceived that a mentorship programme can help to bridge the study-work chasm in the healthcare landscape in Singapore, and will best serve mentors and mentees by committing the proper time and training to ensure its effectiveness.

Introduction: In paediatric practice, healthcare professionals are required to connect with the child and interact at his/her level. However, it can be very difficult for medical students to put themselves in the shoes of the young child, to empathize and understand how a child actually feels while being treated. The Teddy Bear Hospital (TBH) can serve as a platform for medical students to learn how to communicate and empathise with children. Additionally, virtual reality (VR) can be used to portray a child’s viewpoint. This study aims to assess how TBH and VR can improve learning outcomes for medical students. Methods: A cohort study was conducted on 20 first-year medical students taking part in TBH sessions. The medical students did a Pre-, Post- and 1-year Post-intervention Jefferson Scale of Empathy to assess their empathy levels. They also completed a 1-year Post-intervention quantitative and qualitative survey on their experience. Results: There was a significant increase in Jefferson score compared to Pre-intervention (116.95 ± 8.19) for both Post-intervention (121.65 ± 11.03) and 1-year Post-intervention (123.31 ± 8.86). More than 80% believed that participating in TBH improved their confidence and ability to interact with children, while 50% felt that VR scenarios helped prepare them for the TBH. Thematic analysis of qualitative responses described (1) Personal development, (2) Insights into interacting with children, and (3) Structure and curriculum. Conclusion: TBH improved empathy and communication with children among pre-clinical medical students and the use of VR can be used to augment sessions.

Introduction: Nurturing preventive-minded dental students has been a fundamental goal of dental education. However, students still struggle to regularly implement preventive concepts such as caries risk assessment into their clinical practice. The objective of this study was to identify areas in the cariology curriculum that could be revised to help address this. Methods: A total of 10 individuals participated and were divided into two focus group discussions. Thematic analysis was conducted, and key themes were identified based on their frequency of being cited before the final report was produced. Results: Three major themes emerged: (1) Greater need for integration between the pre-clinical and clinical components of cariology; (2) Limited time and low priority that the clinical phase allows for practising caries prevention; and (3) Differing personal beliefs about the value and effectiveness of caries risk assessment and prevention. Participants cited that while didactics were helpful in providing a foundation, they found it difficult to link the concepts taught to their clinical practice. Furthermore, participants felt that they lacked support from their clinical supervisors, and patients were not always interested in taking action to prevent caries. There was also heterogeneity amongst students with regards to their overall opinion of the effectiveness of preventive concepts. Conclusion: Nurturing preventive-mindedness amongst dental students may be limited by the current curriculum schedule, the prioritisation of procedural competencies, the lack of buy-in from clinical supervisors, and a perceived lack of relevance of the caries risk assessment protocol and should be addressed through curriculum reviews.

The study investigated the direction of causality between population variables and economic growth in Nigeria between 1986 and 2020 using VAR Granger Causality/Block Exogeneity Wald Tests. The results of the findings revealed the existence of feedback effects among economic growth, death rate, birth rate and secondary school enrollments. The results further showed that population growth and per capita GDP growth are completely independent and that higher population growth rate did not translate to higher economic growth in Nigeria. The study concluded that an average population growth rate in Nigeria was not seen as being productive as it did not translate to economic growth.

In accelerating spatial planning, an effective instrument is needed in planning so that the implementation of space utilization is in accordance with the expected goals, so that resources remain efficient, investment calculations become more real, and environmental balance in sustainable urban development is maintained. Housing development is often delayed (planning delay) due to the inefficient land provision process. On the other hand, the housing backlog is increasing to 800,000 units per year, thus it is necessary to investigate the effectiveness of planning, especially in the housing sector that has been running in Indonesia. Econometry as a quantitative approach with various variances of analysis techniques has many benefits but has not been widely integrated in planning, especially in calculating the effectiveness of instruments in achieving spatial planning goals. This article aims to examine the effectiveness of planning, especially related to land value and housing development through an econometric model approach by taking samples in Surabaya. The technique used is multiple regression analysis which shows the level of influence between six independent variables, namely land area, building area, land value, land price increases, property prices, and property taxes on the dependent variable, namely the effectiveness of planning indicated in the form of time required to implement the plan. The results show that there are 3 variables of the 6 independent variables that are proven to have an influence based on their significance value, namely land area, land value, and the percentage of increase in land value. Based on the regression results, it takes an average of -0.274 years to be constant, if other variables are considered absent, or it is interpreted that the phenomenon of housing development tends to precede or independent of housing planning in the sectoral plans and spatial plans.

Kerajinan merupakan kegiatan yang berkaitan dengan barang yang dihasilkan melalui keterampilan tangan manusia. Karena kerajinan ini dapat menghasilkan hiasan atau barang seni yang dapat dipakai serta dapat mengahasilkan nilai jual yang tinggi. Membuat kerajian tidak hanya memerlukan barang yang baru tetapi dapat juga memanfaatkan barang-barang bekas seperti handuk bekas dan pita satin bekas. Tujuan dari pengabdian ini adalah memberikan wawasan terhadap masyarakat dalam memanfaatkan barang-barang bekas khususnya pita dan handuk yang sudah tidak dipakai untuk diolah menjadi barang yang bernilai. Metode pelaksanaan dalam pengabdian ini dilakukan dengan melalui sosialisasi, demo tentang pembuatan bunga dari pita satin bekas dan pembuatan vas dari handuk bekas. Kegiatan ini dilakukan Bersama-sama dengan Ibu-ibu PKK, pemuda dan pemudi karangtaruna serta masyarakat penggerak UKM desa Pengulu Kecamatan Sidayu, Kabupaten Gresik. Hasil dari pengabdian ini menunjukkan bahwa masyarakat merespon dan menerima kegiatan dalam pembuatan vas bunga dari handuk bekas dan bunga dari kain satin bekas. Bahkan hasil olahan barang bekas ini dapat dijadikan sebagai bisnis baru. Karena barang-barang olahan ini bisa menjadi sector UKM yang dapat meningkatkan perekonomian keluarga di Desa Pengulu. Namun, salah satu kendala yang ditemukan adalah kurangnya metode pemasaran yang dilakukan masyarakat Pengulu, mereka hanya menunggu dan mengirimnya pada satu tempat pengelola yakni KOBE (Koperasi Usaha Bersama) Sukses Sejahtera di Kecamatan Sidayu yang selama ini sudah dilakukan. Selain itu, kurangnya wawasan dan jaringan untuk penjualan ke berbagai tempat, alasannya masih minim ptoduk-produk yang dihasilkan. Oleh sebab itu perlu mendapat dukungan dari tim PPM untuk bekerjasama dalam sosialisasi dan pengembangan untuk lebih maju.

Sicurezza integrata e welfare di comunità
Authors: Arcuri Alberto
Published: June 2022

Il volume affronta il rapporto tra la sicurezza integrata (intesa come l’insieme degli interventi assicurati dai diversi livelli territoriali di governo, al fine di concorrere, alla promozione e all’attuazione di un sistema unitario e integrato di sicurezza per il benessere delle comunità territoriali) e il welfare di comunità (inteso come l’insieme delle azioni che istituzioni e comunità territoriali realizzano per creare un senso condiviso di benessere e una maggiore inclusione sociale). L’obiettivo è quello di offrire un contributo alla riflessione che, negli ultimi tempi, si va sviluppando intorno all’evoluzione che ha aperto la nozione giuridica di sicurezza oltre il nucleo primigenio della tutela all’integrità fisica delle persone e dei loro beni, per agganciarla alla questione sociale e ai temi del welfare, con un approccio integrato non solo a livello istituzionale, ma anche sociale, grazie all’apporto di quella “capillare” rete di prossimità fatta di singoli cittadini, enti e associazioni del c.d. privato sociale. I diversi contributi ospitati, in questo senso, offrono uno sguardo, interdisciplinare e teorico-pratico, su alcune delle principali manifestazioni di tale complesso rapporto. Infatti, se la sicurezza integrata deve essere intesa come una richiesta di protezione complessiva, allora essa non può prescindere né dai meccanismi attraverso cui la Repubblica garantisce i diritti e redistribuisce risorse e oneri, né dalla partecipazione attiva dei cittadini e delle comunità, le cui energie possono (e devono) essere valorizzate non solo nella realizzazione di specifici interventi, ma anche nella loro ideazione e programmazione, in conformità con le recenti previsioni del Codice del Terzo settore.

This study was carried out to investigate external and internal egg quality traits of different quail lines housed in a multitier cage system. The study was performed on eggs of three different lines of quail as wild type, recessive white and black cross-line stock raised for commercial production. All flocks in the experiment were housed in same environmental conditions for quail and fed same diets during the experiment. A total of 60 eggs from each quail lines were used to determine internal and external egg quality traits. Quail eggs were examined for both internal and external quality characteristics. The eggs from cross-line black coloured quails had significantly greater weight (P<0.01) and it needs more force to crack significantly than the other eggs to break (P<0.012). The black line of quails had significantly greater egg shell thickness than the other line quails (P<0.001). The white line quail eggs had significantly lowest egg length and highest shape index values (P<0.001, P<0.001). The egg yolk of white lines had a significantly lighter yellow than wild and black lines (P<0.003). In conclusion, it seems that the eggs of black coloured lines were relatively superior to wild and white coloured quail groups.
