Counting Everyone: PMM, a Model for Electoral Reform in Canada
Authors: Osberg Brendan
Published: October 2019

Declining voter participation, strategic-voting campaigns, public opinion polls, and myriad other signals highlight the need to improve Canada's current first-past-the-post electoral system. How the system ought to be changed, however, remains unclear. This paper briefly reviews candidate models for electoral reform from other nations, before putting forward the parsimonious mixed-member (PMM) model. This model was inspired by the mixed-member (MM) proportional representation system, as currently used in, for example, Germany. It is 'parsimonious', however, in the sense that the number of additional MPs brought into parliament to reach proportionality is minimized. Like traditional MM, PMM preserves the individual relationship between every voter and an MP, and it eliminates under-representation of parties. Unlike traditional MM, however, it also preserves the incentive for parties to win local races, it avoids unnecessary dilution of constituency representatives, and it avoids misattributing spoiled ballots to major parties. As such, it can be thought of as an optimization of MM. A key feature of this model is conservatism -it modifies our existing system with the minimal set of changes necessary to resolve the most obvious problems in the current system, without creating new ones. It fixes only what is broken.
Comparative Study of Treatment Response and Toxicity of Four Field Box Technique Versus Two Field Technique External Beam Radiotherapy in Locally Advanced Carcinoma Cervix
Authors: Shrestha Roshani , Acharya Bibek
Published: October 2019

Introduction: External beam radiotherapy plays a pivotal role in locally advanced carcinoma cervix. EBRT treats the whole pelvis including the primary tumor along with the regional lymph nodes. Conventionally, EBRT planning is based on standard bony landmarks using X-rays and can be delivered by anterior–posterior and posterior–anterior (AP-PA) parallel opposed fields or the four field box technique. AP-PA field technique provides good coverage to the target volume. Four field box technique with parallel opposed AP-PA fields and two lateral opposed fields although has better dose distribution and decrease normal tissue toxicity, is time consuming. EBRT by AP-PA two field technique is generally used in our center due to less manpower and resources and huge load of patients. But, pelvic radiotherapy by 4 field portals has been proven by the trials that it has better tumor response. So, the objective of this study was to compare the tumor response and acute hematological and non- hematological toxicities between the two techniques.

Methods: One hundred and twenty patients with diagnosis of carcinoma cervix were enrolled in this study, sixty assigned in each group. Group A received radiation by AP-PA two field technique and Group B by 4 field box technique. Chemotherapy regimen was the same for the two groups. Treatment response and toxicities were evaluated after the completion of treatment and compared between two groups.

Results: All enrolled patients received planned treatment. The total duration of treatment in both the groups was 23 days. Loco-regional control with complete remission was 63.3 % in group A Vs. 73.3% in group B (p= 0.405). Acute toxicities of grade 1 and grade 2 were seen more in group A compared to group B, nausea (63.3% vs. 56.7% p=0.141), vomiting (13.3% vs. 20% p=0.234), diarrhea (10% vs. 6.7%), radiation dermatitis (3.3% vs. 0%). Hematological toxicities like anemia, thrombocytopenia and leucopenia were observed more ingroup A than group B.

Conclusion: Both two and four field box techniques are equally effective and feasible as statistically insignificant difference in the response rate and acute toxicities was observed in the two groups.

Published: October 2019

Introduction: This study aims to analyze the clinical presentation and management outcomes carcinoma of vulva managed B. P. Koirala Memorial Cancer Hospital.

Methods: A descriptive study was conducted of all carcinoma of vulva cases managed at B. P. Koirala Memorial Cancer Hospital from 1999 to 2009. The case record of all women diagnosed to have carcinoma of vulva were retrieved and socio-demographic characteristics, clinical presentations, histological type, treatment modalities and outcome were obtained and analyzed.

Results: There were 5152 gynecological malignancies and vulvar cancer accounted for 87, giving a prevalence of 1.7%. The ages ranged from 17 to 86 years (mean of 48.6 years). Parity was 0-10. Vulva wound and pruritus were the most frequent clinical features with presentations in stage I -8%, stage II- 28%, stage III – 52 % and stage IV -12%. Squamous cell carcinoma (93%) predominated and 62% were grade I. Among the 87 cases, 32% were treated primarily with surgery, 34% primarily with concurrent chemo-radiation and 28% with combined modality. Clinical follow-up of one to five years showed that 26 (30%) cases had local recurrence and 22 (25%) died of disease.

Conclusion: Carcinoma of the vulva is a rare gynecological malignancy in Nepal. Surgery and radiotherapy remain to be the mainstay of treatment. Delayed presentation still results in greater morbidity and mortality rates.
Teachers' Perception on Postmethod Pedagogy in EFL Classes of Nepal
Authors: Paudel Pitambar
Published: October 2019

Discussion on the use of method and postmethod in teaching English has become a debatable issue in Nepal. Many methods emerged as reaction to others claiming each of them as the best one but questions of their practicality and utility led to the development of postmethod pedagogy. This pedagogy empowers teachers' autonomy in the classroom and encourages them to design the best alternative way from the choices on the basis of their experience, knowledge and the context. However, the inclination to method is also on the rise. Supports claim that no practice will be method free. In this context, this study attempts to explore the teachers' perception on postmethod pedagogy in English as Foreign Language (EFL) classes of Nepal. In order to achieve the designated objective, the descriptive phenomenological research design was used and 12 teachers who are teaching English at different schools in Pokhara were purposively selected. The data revealed that teachers have a positive and hopeful experience towards postmethod pedagogy and want to open quality changes in English language teaching, developing context and culture sensitive pedagogy.
“Sorry Not Sorry”: Apologizing in the Wake of #MeToo
Authors: MacArthur Michelle
Published: October 2019

This article explores what it means to apologize for misconduct in the #MeToo era through three examples from the Canadian theatre industry: a private apology (Randolph College for the Performing Arts), a public apology (Citadel Theatre), and an absent apology (Soulpepper Theatre). Understanding a public apology as a performative utterance meant to restore a community’s trust, this article suggests the importance of examining the paratexts generated by and around it that help it achieve its function. From policy revisions, to media interviews, to public forums, these materials and events are crucial in the meaning-making process in which a #MeToo apology is engaged, especially when the theatre community’s access to the apology itself is limited. The article concludes by situating its case studies in relation to issues of misconduct in theatre education and training institutions.

Published: October 2019

Graphene oxide (GO) is a carbon-based filler which possesses superior properties for the preparation of polypropylene (PP) nanocomposites. The homogeneous dispersion of nanofiller in a polymer matrix involves a compatibility between base and matrix. This research work analyzes the behavior of GO and its distribution in PP as well as the morphological, physical and mechanical properties of prepared nanocomposites. Since PP is non-polar and GO is polar, there may be a compatibility mismatch between filler and matrix, which may not lead to homogeneous distribution due to poor chemical interaction. Maleic-anhydride grafted polypropylene (MA-g-PP) was selected as a suitable compatibilizer in order to disperse filler into the matrix. X-ray diffraction (XRD) reveals an increase in intergallery spacing which confirms the formation of GO. Scanning electron microscopy (SEM) shows the improved distribution of GO sheets in the PP matrix for the compatibilized system. Tensile strength and modulus of elasticity are improved for the compatibilized PP nanocomposites when compared to the uncompatibilized and to the pure system. Moreover, an enhancement of storage modulus was evidenced for compatibilized nanocomposites. Polar-polar interaction between GO and compatibilizer leads to the homogeneous distribution of filler into the matrix which is clearly responsible for an improvement in the technical properties of polymer.
Influence of the moisture state of recycled fine aggregate on the impermeability of concrete
Authors: Zhuang Yizhou , Liang Yongning , Nabizadeh Azam , Ng Zhen , Ji Tao
Published: October 2019

The impermeability of recycled fine aggregate concrete (RFAC) with different contents of recycled fine aggregate (RFA) was tested according to the standard test method of ASTM C1202. The moisture states of RFA were controlled at air-dried (AD), oven-dried (OD) and saturated surface-dried (SSD) states. Both the interfacial structure and the pore structure of RFAC were analyzed. Research results show that, for the same total water-cement (TWC) ratio and the same content of RFA, the interfacial transition region of RFAC became denser by increasing the moisture amount of RFA from oven-dried, air-dried to a saturated surface-dried state; meanwhile, the density and porosity of hardened cement paste (HCP) improved as well, which resulted in the higher impermeability of RFAC. Whereas by contrast, for the same moisture state and by increasing the RFA content, both the interfacial transition region and the property of the interface structure of RFAC became weaker. Also, the decreasing density and porosity of HCP resulted in lower impermeability of RFAC.

Published: October 2019

The current paper describes material from Medvezhyi Klyk Cave Late Pleistocene–Holocene deposits that represented mostly by isolated teeth. The morphology and size variation of the first lower teeth (n = 542) were studied. There are Alexandromysfortis, A. cf. maximowiczii, A. cf. oeconomus, A. cf. mongolicus determined in the material. We could not determine the taxa due to uncertainty in a spatial variation of the species ranges during Late Pleistocene and Holocene, a broad variety of the m1 anteroconid shape among medium-sized species of voles, and supposed presence “archaic” and “deviant” morphotypes of m1. Geometric morphometrics methods were shown the broad variety of the m1 anteroconid shape without strict species-relation, i.e., each tooth shows proper anteroconid shape, which can repeat within limits in populations in and among species.
Un sous-groupe de cancer gastrique positif au virus d’Epstein-Barr (EBV) identifié pour sa sensibilité à l’immunothérapie
Authors: Grazziotin-Soares D. , Lotz J.-P.
Published: October 2019

Plusieurs études ont montré une association entre l’infection par le virus d’Epstein-Barr (EBV) et la survenue de nombreux cancers chez l’homme, dont certains carcinomes gastriques. Le potentiel oncogénique de l’EBV a été largement exploré, mais les mécanismes précis de la carcinogenèse ne sont pas complètement compris. Les protéines virales codées par EBV sont connues pour notamment déréguler des voies de signalisation de la réponse aux dommages de l’ADN (DDR). Cette inactivation du DDR entraîne alors un accroissement de l’instabilité génomique qui favoriserait la transformation cellulaire pour générer des cellules malignes. Dans un article récemment publié dans la revueNature Medicine, une caractérisation moléculaire des tissus tumoraux et de l’ADN tumoral circulant (ADNtc) provenant de patients non sélectionnés atteints de cancer gastrique métastatique, traités par pembrolizumab, a été réalisée. Ces travaux ont montré que, dans la cohorte étudiée, une forte corrélation pouvait être établie entre la positivité de PD-L1, EBV(+) et MSI-H. Ces résultats suggèrent que le cancer gastrique EBV(+) pourrait être, à l’instar des tumeurs MSI-H, une cible à fort potentiel pour observer un bénéfice clinique de l’immunothérapie. Ainsi, le statut EBV pourrait servir, en clinique, de biomarqueur pour identifier les patients atteints de cancer gastrique, pouvant bénéficier ou non d’une immunothérapie. Au-delà de leur intérêt clinique, ces travaux ouvrent également la voie vers une meilleure caractérisation des mécanismes moléculaires sous-tendant ce phénomène.
The Changing Portrayal of Dancers in Egyptian Films
Authors: Bracco Carolina
Published: October 2019

This article examines the projected image of dancers in Egyptian cinema. The historical background includes the last period of the Farouk monarchy, the revolution of the Free Officers Movement and the Nasser regime, ending with Nasser’s death in 1970, when a new social and political era started blossoming. I consider the socio-political changes and their cultural repercussions as part of a dialectic relationship that affects the portrayal of dancers in three films: The Lady’s Puppet (1946), My Dark Darling (1958) and Pay Attention to Zuzu (1972). By examining Carioca’s roles in these films, I argue socio-political changes in Egypt have been projected on the image of the dancer while also changing it: she is first seen as a working woman, then as an evil woman and finally as a marginalised woman.
Why Draw Flowers?
Authors: Marnin-Distelfeld Shahar , Gorney Edna
Published: October 2019

Botanical art and illustration, presented alongside scientific descriptions, were at the heart of Jewish national projects during the British Mandate in Palestine-Israel and following the establishment of the state of Israel in 1948. Looking back, we recognised three prominent women artists who contributed widely to many such botanical projects: Ruth Koppel, Esther Huber and Bracha Avigad. This study aims to investigate the plant images these three artists have created. We will do so by using the approach of visual anthropology while focusing on two main aspects: the connection between botanical illustration and national identity, and the link between botanical art and gender. This study is the first to demonstrate that botanical art in Israeli culture has been gendered, with women doing most of the work, in agreement with findings from Western culture.
A Film Never Completed
Authors: Nathansohn Regev
Published: October 2019

This is a story and analysis of a film production that has never materialised. The case study features a group of neighbourhood residents who wished to produce a film representing their experiences of living in a mixed neighbourhood in the northern Israeli city of Haifa, where Jews and Arabs live together. The ethnography of their work documents the incommensurability between the social interactions within the group and the content of the film’s script. While the group dynamic reflected the mixing atmosphere of the neighbourhood, their script succumbed to the hegemonic discourse of separation in Israel and to steering away from ambiguities. The group’s aspiration to create a realistic representation required a political and visual language that was not available as an objective possibility and thus was challenging to imagine.

Published: October 2019

OBJECTIVE

Nonunion is a common complication of spinal fusion surgeries. Electrical stimulation technologies (ESTs)—namely, direct current stimulation (DCS), capacitive coupling stimulation (CCS), and inductive coupling stimulation (ICS)—have been suggested to improve fusion rates. However, the evidence to support their use is based solely on small trials. Here, the authors report the results of meta-analyses of the preclinical and clinical data from the literature to provide estimates of the overall effect of these therapies at large and in subgroups.

METHODS

A systematic review of the English-language literature was performed using PubMed, Embase, and Web of Science databases. The query of these databases was designed to include all preclinical and clinical studies examining ESTs for spinal fusion. The primary endpoint was the fusion rate at the last follow-up. Meta-analyses were performed using a Freeman-Tukey double arcsine transformation followed by random-effects modeling.

RESULTS

A total of 33 articles (17 preclinical, 16 clinical) were identified, of which 11 preclinical studies (257 animals) and 13 clinical studies (2144 patients) were included in the meta-analysis. Among preclinical studies, the mean fusion rates were higher among EST-treated animals (OR 4.79, p < 0.001). Clinical studies similarly showed ESTs to increase fusion rates (OR 2.26, p < 0.001). Of EST modalities, only DCS improved fusion rates in both preclinical (OR 5.64, p < 0.001) and clinical (OR 2.13, p = 0.03) populations; ICS improved fusion in clinical studies only (OR 2.45, p = 0.014). CCS was not effective at increasing fusion, although only one clinical study was identified. A subanalysis of the clinical studies found that ESTs increased fusion rates in the following populations: patients with difficult-to-fuse spines, those who smoke, and those who underwent multilevel fusions.

CONCLUSIONS

The authors found that electrical stimulation devices may produce clinically significant increases in arthrodesis rates among patients undergoing spinal fusion. They also found that the pro-arthrodesis effects seen in preclinical studies are also found in clinical populations, suggesting that findings in animal studies are translatable. Additional research is needed to analyze the cost-effectiveness of these devices.

The influence of roughness in the equilibrium problem in lubrication with imposed load
Authors: Ciuperca I. , Jai M. , Tello J.I.
Published: October 2019

In this article we study a lubricated system consisting on a slider moving over a smooth surface and a known external force (the load) applied upon the slider. The slider moves at constant velocity and close proximity to the surface and the gap is filled by an incompressible fluid (the lubricant). At the equilibrium, the position of the slider presents one degree of freedom to be determined by the balance of forces acting on the system: the load and the total force exerted by the pressure of the lubricant. The pressure distribution is described by a variational inequality of elliptic type known as Swift–Stieber model and based on Reynolds equation. The distance h between the surfaces in a two dimensional domain Ω is given by [Formula: see text] where [Formula: see text] for [Formula: see text] and [Formula: see text] for y being the homogenization variable.

The main result of the article quantify the influence of the roughness in the load capacity of the mechanism in the following way: [Formula: see text] then, the mechanism presents finite load capacity, i.e. [Formula: see text]. Infinite load capacity is obtained for [Formula: see text] and [Formula: see text]. A one dimensional particular case is given for [Formula: see text] with infinite load capacity.
Force performance investigation of linear induction motor for low-speed Maglev train with an improved equivalent circuit model
Authors: He Yunfeng , Zhan Jiawen , Lu Qinfen
Published: October 2019

In order to fast calculate the thrust force and normal force of linear induction motor (LIM) for low-speed maglev train under overall conditions including traction and braking, this paper proposes an improved equivalent circuit (EC) method. Firstly, the improved equivalent circuit model is proposed based on the traditional one by adopting a precision correction factor, which can accurately consider the transverse edge effect of cap-shape secondary conducting sheet. Moreover, the permeability of back-iron and magnetic inductance are amended considering the saturation effect. The corresponding calculation procedure is given out. Then, the precise correction factor is investigated based on 2D finite element (FE) model. By comparison with the traditional Russell and Norsworthy correction factor (RNF), the precision correction factor is proved to be more suitable to LIM with wide-range slip frequency. Finally, the thrust force and normal force of LIM with different slip frequency are predicted under braking and traction conditions by improved EC method. The predicted results and the proposed method are validated by 3D FE method and experiment results.

Published: October 2019

The following study aims to evaluate the changes in profile of selected sugars and content of polyols in the apple tissue after osmotic dehydration. What makes this research innovative is the use, in the osmotic pre-treatment, of solutions which have hitherto not been commonly used in fruit processing by researchers worldwide. Selected substances from the polyols group (erythritol, xylitol, and maltitol) were used as osmotic agents in 30 % concentrated solutions. The ideal osmotic pressure, as well as efficiency of the process, was calculated, and these parameters were the highest in the case of erythritol. It was confirmed that type of osmotic solution and time of the process have significant influence on discussed parameters. Osmotic dehydration in polyols solutions resulted in increasing the content of these compounds during the process and minor changes in sugars profile of apple tissue. Color changes caused by pre-treatment were small, but still they could be noticed by an inexperienced observer.

Strawberry is an accessory fruit stimulated by cold weather as a berry, reported to constitute, phenolic acid, ellagic acid and its derivatives EA-4-arabiniside, EA-4-acetylarabinoside, EA-4-acetylxyloside, β-carotenoids (Lutein, β-carotene), omega-3 fatty acids and derivatives. Fruits especially berries/soft fruits have combination of antioxidants and phytochemicals. the phenolic compounds present in strawberries are responsible for antioxidant properties rather than to vitamin C and these dietary antioxidants prevent or limit the potential cancer-inducing oxidative damage.  These compounds play a synergistic and cumulative role in health promotion. The risk of persistent diseases and oxidative damage to the cellular system can also be prohibited or lowered by these antioxidant compounds (phytochemicals), such as phenolics and carotenoids Strawberries enhance the palatableness of a cholesterol-dropping food whereas it maintains the serum lipid reductions of the food consumed. Cognitive and motor functions are age-related declines that are slowed by strawberry intake and it also has cancer fighting constituents, it also has a potential of decreasing the risk of heart diseases, the females with high strawberry ingestion have reduced levels of an inflammatory marker in their blood. Strawberry extract was found to decrease the activity of transcription factors involved in tumor promotion and there is a need to consume sufficient amounts of antioxidants avoid or reduce the oxidative stress stimulated by free radicals

Metabolic engineering of the biofuel-producing Zymomonas mobilis is necessary if we are to unlock the metabolic potential present in this non-model microbe. Manipulation of such organisms can be challenging because of the limited genetic tools for iterative genome modification. Here, we have developed an efficient method for generating markerless genomic deletions or additions in Z. mobilis. This is a two-step process that involves homologous recombination of an engineered suicide plasmid bearing Z. mobilis targeting sequences and a subsequent recombination event that leads to loss of the suicide plasmid and a genome modification. A key feature of this strategy is that GFP expressed from the suicide plasmid allows easy identification of cells that have lost the plasmid by using a fluorescence activated cell sorter. Using this method, we demonstrated deletion of the gene encoding lactate dehydrogenase (ldh) and the operon for cellulose synthase (bcsABC). In addition, by modifying the plasmid design, we demonstrated targeted insertion of the crtIBE operon encoding a neurosporene biosynthetic pathway into the Z. mobilis genome without addition of any antibiotic resistance genes. We propose this approach will provide an efficient and flexible platform for improved genetic engineering of Z. mobilis.

This study aimed to determine the effect of irrigation amount and irrigation frequency on drip-irrigated flue-cured tobacco evapotranspiration (ETa), yield, and water use efficiency. Four irrigation treatment levels were imposed: 100% IRT (fully irrigated treatment, no stress), 85% IRT, 70% IRT, RFT (rainfed treatment), and high, medium, and low irrigation frequencies were set. The relationship between irrigation volume and yield is a quadratic curve. The evapotranspiration had a positive relationship with the irrigation amount. The yield of flue-cured tobacco was the highest in 2016 (wet year), and the corresponding ETa was the smallest. The irrigation water use efficiency (IWUE) in the driest year, 2017, was lower than IWUE in the wet years 2015 and 2016, and the crop water use efficiency (CWUE) had similar results for the three years. IWUE increased with irrigation amount. The effect of irrigation frequency on CWUE was not significant. The CWUE had a positive relationship with yield. No significant differences due to irrigation frequency were found for yield.

Nitrogen (N) in soybean (Glycine max L.) plants derived from biological nitrogen fixation was shown to be a sustainable N resource to substitute for N fertilizer. However, the limited water supply in sandy soil is a critical factor for soybean nodulation and crop growth. This study investigated the potential mechanism of the effect of biochar and irrigation on the soybean-Rhizobium symbiotic performance and soil biological activity in a field trial. In the absence of N fertilizer, 10 t ha−1 of black cherry wood-derived biochar were applied under irrigated and rainfed conditions on an experimental, sandy field site. The plant biomass, plant nutrient concentrations, nodule number, nodule leghemoglobin content, soil enzyme activities, and soil-available nutrients were examined. Our results show that biochar application caused a significant increase in the nodule number by 35% in the irrigated condition. Shoot biomass and soil fluorescein diacetate hydrolytic activity were significantly increased by irrigation in comparison to the rainfed condition. The activity of soil protease reduced significantly, by 8%, with the biochar application in the irrigated condition. Further, a linear correlation analysis and redundancy analysis performed on the plant, nodule, and soil variables suggested that the biochar application may affect soybean N uptake in the sandy field. Nodulation was enhanced with biochar addition, however, the plant N concentration and nodule Lb content remained unaffected.

Monitoring plant water status is relevant for the sustainable management of irrigation under water deficit conditions. Two treatments were applied to an early-maturing nectarine orchard: control (well irrigated) and precise deficit irrigation (PDI, based on soil water content thresholds). Moderate water deficits generated by PDI were assessed by comparing terrestrial: stem water potential (Ψstem) and gas exchange parameters, with remote: canopy temperature, normalized difference vegetation (NDVI), and soil adjusted vegetation index (SAVI), plant water status indicators. The Ψstem was the only indicator that showed significant differences between treatments. NDVI and SAVI at the postharvest period were appropriate indexes for estimating winter pruning, although they did not serve well as plant stress indicator. Vapor pressure deficit along with Ψstem values were able to predict remote sensing data. Ψstem and canopy to air temperature difference values registered the highest signal intensity and NDVI the highest sensitivity for detecting water deficit situations. The results suggest that care should be taken when using instantaneous remote indicators to evaluate moderate water deficits in deciduous fruit trees; more severe/longer water stress conditions are probably needed. The proposed PDI strategy promoted water saving while maintaining yield, and could be considered a promising tool for semi-arid agrosystems.

The study evaluated the anti-colibacteriosis efficacy of herbs in experimental infection by rabbit pathogenic strain of E. coli O103 eae+. It also studied the effects of herbal mixture added to feed or water on blood parameters. This animal model was used since some E. coli strains pathogenic for rabbits are similar to the strains that are pathogenic to humans. The components of herbal extracts were Rumex crispus, Pontentilla anserine, and Polygonum aviculare. Supplementation was carried out in water (ExpW group) or feed (ExpF group), and four weeks later the animals were infected with the E. coli O103 eae+ strain. The administration of herbs increased the mean concentration of total protein and serum albumin (p < 0.01) without causing disturbances of electrolyte and acid-base balance. The highest total antioxidant capacity (TAS) value (p < 0.01) was observed in the ExpF group. The administration of a mixture of herbs and feed caused more reduction in the number of E. coli in cecum than supplementation into water after an experimental infection. The herbs applied in rabbits did not harm the secretory functions of liver, electrolyte, and acid-base balance of the blood. The application of the tested herbal mixtures can control the activity of the intestinal microbial community.

Carcass parameters and meat quality in lambs that consumed diets having layer hen litter (LL) were evaluated in a complete randomized study. Forty-two lambs were allocated equally (14 lambs/treatment diet) into one of three iso-nitrogenous diets for 75 days. To partially replace soybean meal and barley, LL was given at 0 (LL0), 150 (LL150), or 300 g/kg (LL300) of dietary dry matter (DM). At the termination of the trial, the characteristics of carcasses (hot and cold carcass weight, dressing percentage, and carcass cuts) and meat quality (Musculus longissimus linear dimensions, ultimate pH, cooking loss, water holding capacity (WHC), shear force (SF), color coordinates) were measured after slaughtering all lambs. Longissimus muscle weight was greatest (p < 0.05) for the LL150. For the dissected loin, intermuscular fat content was lowest for the LL0 diet. However, subcutaneous fat content was lower (p < 0.05) in the LL300 diet than LL0 and LL150 diets. Rib fat depth and Musculus longissimus area were greater (p < 0.05) for LL150 than L0. No differences were found in meat pH or color parameters among treatments but WHC and SF were lower in L0 lambs than in lambs fed LL containing diets. Cooking loss was greater for the LL300 diet than the LL0 diet. In summary, quality of meat and carcasses data indicate the possibility of inclusion of LL up to 300 g/kg DM to growing Awassi lambs.
