Impacts of Human Modifications on Material Transport in Deltas
Authors: Hariharan Jayaram , Wright Kyle , Moodie Andrew , Tull Nelson , Passalacqua Paola
Published: December 2022

Abstract. As humans continue to inhabit and modify river deltas, the natural processes governing material transport through these landscapes are altered. Two common engineering projects undertaken on deltas are the dredging of channels to enable shipping and the construction of embankments to reduce flooding. While the impact of these topographic modifications has been studied at a local-level for specific sites, there is a gap in our generalized understanding of how these landscape modifications impact material transport. To narrow this gap, we conduct exploratory numerical modeling to develop deltaic landscapes with different input sediment compositions, modify their topography to mimic dredging and embankments, simulate different flow conditions, and then model the transport of passive particles. We find that human modification of topography lowers hydrological connectivity by reducing the area visited by fluvial inputs. The amount of time particles spend within the delta is reduced by the construction of polders and is lengthened by dredging. Material buoyancy has a greater impact on nourishment areas and exposure times than flow regime or topographic modification, with positively-buoyant particles spending longer and visiting a greater area of the delta than neutral and negatively-buoyant material. The results of this study can help guide the design of future engineering projects by providing estimates of their likely impact on transport processes.
Insights into the interaction of a shale with CO2
Authors: Stavropoulou Eleni , Laloui Lyesse
Published: December 2022

Abstract. Caprock formations, such as shales, play a key role in safe underground CO2 storage since they serve as a hydromechanical barrier that prevents migration of the injected CO2 to the surface. While their hydromechanical response is important to ensure their sealing capacity, interaction with the injected CO2 involves additional thermo–hydro–chemo–mechanical (THCM) phenomena that may threaten the long-term integrity of the caprock. The low-transport properties of shales make them a suitable caprock material, but at the same time challenging to study due to the very long timescales (months/years) that are required for the various THCM processes to manifest. In this work, the long-term multiphysical interaction of the Opalinus Clay shale with liquid and supercritical CO2 is studied in 3D with live X-ray tomography. Three-dimensional analysis reveals the localised response of the coupled THCM processes that is often indistinguishable with conventional lab testing protocols. To improve spatial and temporal resolution while applying field-representative pressure and temperature conditions, small-sized samples are studied. Long-term injection of liquid CO2 resulted in significant fissuring of calcite-rich zones that were for the first time visualised and quantified from the X-ray images. Additionally, a re-arrangement of the pre-existing micro-fissures in the clay matrix was observed. The volumetric response during direct exposure of an Opalinus Clay sample to supercritical CO2 revealed an initial swelling at pre-fissured zones and initiation of new micro-fissures at areas of direct contact with the anhydrous CO2 due to pore water evaporation. Advanced 3D image analysis showed an increasing CO2 uptake in the caprock material with time, suggesting potential CO2 trapping in the material.

Abstract. Permafrost has been warming and thawing globally, with subsequent
effects on the climate, hydrology, and the ecosystem. However, the permafrost
thermal state variation in the northern lower limit of the permafrost zone
(Xidatan) on the Qinghai–Tibet Plateau (QTP) is unclear. This study
attempts to explore the changes and variability in this permafrost using
historical (1970–2019) and future projection datasets from remote-sensing-based land surface temperature product (LST) and climate
projections from Earth system model (ESM) outputs of the Coupled Model
Intercomparison Project Phase 5 and 6 (CMIP5, CMIP6). Our model considers
phase-change processes of soil pore water, thermal-property differences
between frozen and unfrozen soil, geothermal flux flow, and the ground ice
effect. Our model can consistently reproduce the vertical ground temperature
profiles and active layer thickness (ALT), recognizing permafrost
boundaries, and capture the evolution of the permafrost thermal regime. The
spatial distribution of permafrost and its thermal conditions over the study
area were controlled by elevation with a strong influence of slope
orientation. From 1970 to 2019, the mean annual ground temperature (MAGT) in
the region warmed by 0.49 ∘C in the continuous permafrost zone and
0.40 ∘C in the discontinuous permafrost zone. The lowest elevation
of the permafrost boundary (on the north-facing slopes) rose approximately
47 m, and the northern boundary of discontinuous permafrost retreated
southwards by approximately 1–2 km, while the lowest elevation
of the permafrost boundary remained unchanged for the continuous permafrost
zone. The warming rate in MAGT is projected to be more pronounced under
shared socioeconomic pathways (SSPs) than under representative
concentration pathways (RCPs), but there are no distinct discrepancies in the areal
extent of the continuous and discontinuous permafrost and seasonally frozen
ground among SSP and RCP scenarios. This study highlights the slow delaying
process of the response of permafrost in the QTP to a warming climate,
especially in terms of the areal extent of permafrost distribution.
Evidence of chronic undernutrition in late 19th century German infants of all social classes
Authors: Hermanussen Michael , Scheffler Christiane
Published: December 2022

125 years ago, European infants grew differently from modern infants. We show weight gains of 20 healthy children weighed longitudinally from birth to age 1 year, published by Camerer in 1882. The data illustrate the historically prevalent concepts of infant nutrition practiced by German civil servants, lawyers, merchants, university professors, physicians, foresters and farmers. Breastfeeding by the mother was not truly appreciated in those days; children were often breastfed by wet nurses or received bottled milk. Bottle feeding mainly used diluted cow’s milk with some added carbohydrates, without evidence that appropriate amounts of oil, butter or other fatty components were added. French children from 1914 showed similar weight gain patterns suggesting similar feeding practices. The historical data suggest that energy deficient infant formula was fed regularly in the late 19th and early 20th century Europe, regardless of wealth and social class. The data question current concerns that temporarily feeding energy deficient infant formula may warrant serious anxieties regarding long-term cognitive, social and emotional behavioral development.

Narratividade e intertextualidade nas paráfrases operísticas de Franz Liszt (1811–1886) sobre as óperas de Vincenzo Bellini (1801–1835)
Authors: Plaça Teixeira Thiago
Published: December 2022

O presente artigo trata da relação de Liszt com a Ópera Italiana do século XIX e propõe um modelo analítico para uma abordagem de suas paráfrases operísticas para piano. Toma-se como parâmetros teóricos: (1) as categorias de intertextualidade musical identificadas em diferentes musicólogos; (2) as tipologias temáticas identificadas por Grabócz nas obras pianísticas de Liszt; e (3) o conceito de narratividade em sua relação com a estruturação da forma musical. Aplicando-se tais premissas a um estudo de caso específico, a fantasia de Liszt sobre La Sonnambula de Bellini, procurou-se mostrar a utilidade de tal abordagem dentro do processo de entendimento da obra para fins de performance.

Authors: Francisco Elaine M. , Hermosa Jherwin P. , Ofrin Darwin D.
Published: December 2022

This study aims to determine the relationship between personal motivational factors and job-related factors as measure of employee satisfaction in the workplace. Through descriptive-correlational research design, a total of 100 teaching and non-teaching personnel of a state university were surveyed to determine their personal motivational factors and the job-related factors they consider to stay in their job. The result showed a positive relationship between various motivational factors such as health and wellness, rewards and recognition, peer support, work-life balance and work environment and the working environment factors including the workload and job description. In addition, the organization's role induces high level of motivation to the individual employees. It also shows that all of the motivation factors as well as the job-related factors truly motivate employees to work with satisfaction. The significant relationship exists on the input and output variables showed that health and wellness, rewards and recognition, fear, peer support, work life balance and work environment greatly help the respondents to understand better their roles performed in the organization.

Authors:   Education Leadership Consultancy, Budgell Phil
Published: December 2022

A major reform of the Mathematics curriculum was published in England in 2016, implemented in 2017 and examined in 2019. In Bulgaria, the analogous reform was published in 2018, will be implemented in 2020 and examined in 2022. This paper takes the framework developed by Budgell and Kunchev (2019) and seeks to interpret the new curricula in terms of the Students, the State and the Curriculum with an introduction to Assessment. In terms of the Curriculum, the paper examines, at the highest level, General and Specific Objectives; followed by Overarching Themes; then the Topics covered and finally the Detailed Content Statements for each topic. The paper concludes that the real differences between the teaching of Mathematics in England and Bulgaria lie not in the Mathematics itself but in the overall curriculum and assessment frameworks within which Mathematics is taught.

Засоление почв является серьезной проблемой Республики Казахстан. Один из путей повышения толерантности сельскохозяйственных культур к солевому стрессу – использование сообществ эндофитных микроорганизмов, повышающих устойчивость растений к различным повреждающим воздействиям. В данной работе показано влияние эндофитов растений, произрастающих в засушливых условиях, на способность проростков пшеницы противостоять солевому стрессу. Наилучшие результаты на синтетической среде показала ассоциация из растения Erigeron canadensis в сочетании с эндофитным актиномицетом пшеницы, отнесенным к виду Streptomyces curacoi. Влияние предварительной адаптации эндофитных микроорганизмов к хлориду натрия на устойчивость растения-хозяина к засолению было показано нами впервые.

Soil salinization is a serious problem in the Republic of Kazakhstan. One of the ways to increase the tolerance of agricultural crops to salt stress is the use of communities of endophytic microorganisms, which increase the resistance of plants to various damaging effects. This work shows the influence of endophytes of plants growing in arid conditions on the ability of wheat seedlings to withstand salt stress. The best results on a synthetic medium were shown by an association from the plant Erigeron canadensis in combination with an endophytic wheat actinomycete assigned to the species Streptomyces curacoi. The influence of the preliminary adaptation of endophytic microorganisms to sodium chloride on the resistance of the host plant to salinity was shown by us for the first time.

Published: December 2022

Educational resources and facilities cost money. The government and families mostly cover these expenditures. Kenya has spent considerably in education to improve access and participation. Despite these attempts, many students enroll in secondary school in form one, but the numbers drop as they advance to form four. Some are unsuccessful in the four-year course. The study's main goal was to determine the effect of direct educational costs on the transition rates of students in public boarding secondary schools in Uasin Gishu County. This research employed a Convergent Parallel Mixed Methods Design. 34 principals and 3,917 parents were targeted. The sample includes all the 34 principals and 362 parents purposively and Yamane's Simplified formula-selected respectively. Proportional random sampling aided in the choice of parents. Interviews, questionnaires, and archive content analysis collected data. Thematic analysis helped interpret qualitative data while inferential and descriptive statistics interpreted quantitative data. The findings indicated that, in public boarding secondary schools, student transition is highly connected with direct educational expenses. Direct educational expenditures predict public boarding secondary school students’ grade to grade transition rate. They explain 81.8% of the variation with repairs, maintenance and improvement cost accounting for the highest (34.7%) and school meals was responsible for 0.1% of the variance. The study concluded that, direct costs of education affect students’ grade to grade transition. It recommends the government to: review and increase student capitation so as to cover boarding expenses, diversify funding sources to fully cushion the needy students and fully fund school projects and programmes in order to relieve parents/guardians of the cost burden and thus increase student participation in Public Boarding Secondary schools.

Published: December 2022

Zinc oxide nanoparticles (ZnO NPs) have recently been studied as a multi-functional and multi-target nanomedicine for cancer treatment. They can be used not only as a nanocarrier for delivery of the chemotherapy drug but also as an antiradical agent due to their photo-catalytic and photo-oxidizing abilities. Our previous work showed a potential use of commercial-available ZnO NPs without and with carboplatin for the treatment of retinoblastoma. The aim of this work was to synthesize ZnO NPs having smaller particle size than the commercial ones, i.e., 100 nm average diameter, in order to improve the reaction time. ZnO NPs were prepared by a sol-gel technique and calcined with different calcination conditions. The structure and particle size of ZnO powders were characterized using an x-ray diffractometer and a particle size analyzer. Average nanoparticle sizes of 16.32 ± 1.64 nm were achieved at a calcination temperature of 300 degree Celsius and 1 hour holding time. The antiradical activity of prepared ZnO NPs in cooperation with ultraviolet irradiation was assessed using a putative model of cancer cells, i.e., 2,2(diphenyl-1-picryhydrazyl) radicals (DPPH*). An optical spectroscopy was used to detect the decrease in peak absorbance of the antiradical solution at a wavelength of 515 nm, which in turn can be used to calculate the percent remaining of DPPH*. The disappearance of DPPH* with respect to the reaction time revealed that prepared ZnO NPs (16.32 ± 1.64 nm) improved response time as compared with ZnO NPs (100 nm). Moreover, the effective ZnO concentrations to reduce the initial DPPH* concentration by 50%, also known as the EC50 value in the present study, is lower indicating the improvement of anti-proliferative activity when compared to the commercial ZnO NPs.

Published: December 2022

An essential aspect of a diagnostic radiology quality assurance program is X-ray image repeat analysis, a systematic process to record rejected or repeated images to determine the cause so we can minimize that image repetition in the future. Some of the disadvantages caused by repeated X-ray photo examinations are giving additional doses to patients (unnecessary exposure), ineffective time for radiology staff and patients (wasting time), and financial losses due to electricity for the X-ray machine and the DR system (unit costs). In January 2021, at the Radiology Installation of Indriati Hospital, repeated X-Ray photos analysis was chosen as one of the quality indicators by Decree No. 031/PER-RSIND/2021. The goal is to look for improvements to minimize repeated X-ray photos occurrence and prevent unnecessary exposure. Monitoring is carried out daily through SISMADAK V5.0.3 and is reported monthly to the KMRS committee. The step for selecting quality indicators for X-ray photo examination repetition has greatly impacted the aspects of radiation protection and safety because it can reduce the number of X-ray photo inspection repetitions by 0.6% from 2020. The continuous improvement step based on the root cause of the fishbone method is with the supervision of a radiographer intensively with OPPE assessment and credentials in the hope of minimizing the repetition of X-ray photos. It can become a fundamental aspect of radiation protection and culture safety, especially in the radiology installation of Indriati-Solobaru Hospital, Sukoharjo, Central Java. Keywords: X-ray photo repetition, quality indicators, fishbone method, radiation safety culture.

The necessary measures taken to limit the effects of the COVID-19 pandemic have had an unfortunate negative effect on the mental well-being of people across the world. The pandemic affected the service delivery of mental health services in Turkey. Unlike many countries, that made use of digital health services and of telephone helplines to respond to increased need for information and support, Turkey had no prior experience with national mental health helplines. It established a national-wide helpline in a short time and responded to calls for information and support. This study looks at the helpline establishment, support given, reasons for calls and referrals, for a period of 12 months. Top reasons for calls included COVID-19 infection or loss of relative, anxiety and need for information. The helplines were essential at the beginning of the pandemic to respond to the need for information and support.

Published: December 2022

In order to solve the problems of time-consuming, poor repeatability and inability to directly reflect the pore structure of the core by traditional experimental methods to obtain the reservoir parameters, a method was proposed to study the pore structure of inner core using digital core and pore network model. Firstly, the core CT scan image is processed by filtering and denoising, threshold segmentation and pore-throat network skeleton extraction. Then, the digital core and pore network model are constructed by digital image technology and maximum sphere algorithm, and the core physical parameters are statistically analyzed. Finally, a digital core pore network model is used to simulate oil-water two-phase flow. The results show that the digital core pore network model can better reflect the real core pore space characteristics and accurately reflect the pore throat distribution and morphology characteristics. Through practical application, the 3D pore network model of a digital core can accurately reflect the core's microporosity and throat structure and fully understand the mechanism of fluid flow in porous media, which has high application value. In addition, the method can be repeated many times, which is time-consuming and controllable and makes up for the limitations of conventional physical experiments.

Significant Challenges in Digital Payments with Reference to Digitalization of Small Retail Stores in Indian Context - A Theoretical Assimilation
Authors: Guddad Daneshwari , Kodaganur Pushparaj
Published: December 2022

Due to the entry of huge supermarket chains and internet merchants, the traditional business model of small retail convenience businesses in India is coming under growing pressure. The digitalization of small retail establishments was examined in this study utilizing a qualitative technique and the Technology-OrganizationEnvironment framework as the theoretical underpinning. Our analysis indicated a high reliance on low value cash and credit-based transactions and low levels of adoption of digital technologies for managing supply-side and customers-side activities. Small retail establishments' capacity to go digital is being hampered by ineffective procedures, shoddy physical infrastructure, inadequate access to and unreliability of digital technologies, and costs. The current digital era is characterized by a significant amount of continuing, ICT-led technological progress and ever-increasing rivalry. New and late entrants are concerned about their future in the face of fierce rivalry, while established enterprises and early entrants are concerned about rising competition and shrinking profit margins. Digital disruption has reduced the lifecycles of company models, making business model innovation essential to attaining financial success. Small retailers' inability to comprehend the changes and resources needed to meet the challenges is evidenced by their expressed ambiguity and inherent contradictions regarding the advantages of transparency, perceived sense of control, tax implications, and mistrust of external regulations in the context of digital commerce.
İnsan Bir Makinedir Savının Dinamik Sistem Kuramı Bağlamında Değerlendirilmesi
Authors: USLU POOYANI Ayşe
Published: December 2022

Bu makale, “insan bir makinedir” iddiasının temel aldığı makine metaforunu, materyalist bir biliş anlayışı perspektifinden sınamayı hedefler. Bu amaçla, bilişselliği modellemek için kullanılan makine metaforlarını bir araya getirip karşılaştırmasını sunar. Buna göre, öz-örgütlenişe sahip canlı sistemlerin bilişsel etkinlik alanını materyalist bir perspektiften bakarak açıklamak için, etkinleşimci yaklaşım berimsel modelin sağladığı kavramsal çerçeveden daha uygundur. Etkinleşimci yaklaşımın en büyük avantajı, Dinamik Sistemler Kuramının sağladığı kavramsal çerçeveyi kullanarak, bilişsellik ve yaşam, biliş ve beden, zaman ve maddesel örgütleniş arasındaki bağı yitirmeden yaşayan sistemlerin temel hareketini materyalist bir zeminde anlamaya izin veriyor oluşudur. Bu bağlamda, bu metnin birinci bölümünde, La Mettrie’in “insan bir makinedir” iddiası, materyalist bir beden ve bilişsel etkinlik anlayışına örnek olarak gösterilmiştir. İkinci bölümde, kullanılan diğer zihin metaforları tarihsel olarak incelenmiş ve günümüz baskın görüşü olan berimsel model mercek altına alınmıştır. Üçüncü bölümde, berimsel modelin problemli yanlarını aşmaya dönük etkinleşimci eleştirisine yer verilmiş ve etkinleşimcilik bedenin bilişsel hareketini anlamaya dönük alternatif bir düşünme biçimi olarak sunulmuştur. Etkinleşimci bağlamda allopoietik ve otopoietik makine kavramları arasında ayrım yapılmış ve otopoietik sistemler olan canlı bedenlerin öz-örgütlenişe sahip, kimlik ve anlamlı eylem örüntüleri yaratma amaçlılığı taşıyan bir yönelimsellikle çevreleriyle eşlenik ilişkiler kuran dinamik sistemler olduğu belirtilmiştir. Son bölümde, bu türden otonom sistemleri anlamak için Dinamik Sistem Kuramı’nın en uygun kavramsal çerçeveyi sunduğu verilen örneklerle gösterilmiştir.
Siyasi ve Askeri Bir Lider Olarak Mustafa Kemal Atatürk ve Yönetim Felsefesi
Authors: SAYGILI Zafer
Published: December 2022

Sosyal oluşumların var olduğu her yerde liderlikte vardır. Bu sebepledir ki, toplumlarda ve örgütlerde liderlik insanlık tarihi boyunca önemli bir konu olmuştur. Mustafa Kemal Atatürk ise yirminci yüzyılın en önemli siyasi ve askeri liderlerinden birisi olarak kabul edilmiştir. Millî mücadele dönemlerinde milli birliği sağlayan bir lider, savaş alanlarında bir komutan ve modern Türk devletini kuran siyasi bir şahsiyettir. Atatürk’ün hem siyasi hem askeri lider olması onun çok boyutlu zekasının açık bir göstergesidir. Atatürk’ün, siyasi liderliğinin kaynağını Türk milletinden ve askeri liderliğinin kaynağını ise milli mücadele ruhundan almaktadır. Türk milletine savaş ve barış zamanlarında askeri ve siyasi kişiliği ile damga vurmuş bir liderdir. Komutan olarak askerlerine savaş alanlarında motivasyon ve siyasi kişi olarak milletine tam bağımsızlık yolunda esin kaynağı olmuştur. Onu öteki liderlerden ayıran en önemli özelliği hem eylem ve hem de fikir adamı olmasıdır. O, halkının tarihini değiştirecek yetenekleri sayesinde, memleketini siyasi ve askeri zaferlerle uçurumun kenarından almıştır. Sonuç olarak, Atatürk çağının ötesine uzanan etkileriyle karizmatik, vizyoner ve insanlık idealine bağlı büyük bir lider olduğu konusunda tarihçiler, düşünürler ve diğer devlet adamları arasında yoğun bir uzlaşım vardır. Bu çalışmanın amacı, tarihi olaylardan hareketle, Atatürk’ün askeri ve siyasi liderlik özelliklerini tartışarak liderlik tarzı çerçevesinde geliştirdiği yönetim felsefesini ortaya koymaktır.

Published: December 2022

Durante as leituras feitas a respeito do respectivo tema percebeu-se que a liberdade de expressão no Brasil ela ganha uma outra proporção com a expansão da internet, preconceitos antigos ganham os ares cibernéticos e devido a este fato o Direito teve que se reinventar através da implementação do Marco Civil da Internet, foi refletindo esta questão que optou-se por tentar entender estes fenômenos que utilizou-se a partir de aspectos histórico-jurídicos, para fundamentá-los foi utilizado livros, artigos e sites informativos, estes foram importantes por fornecer dados relativos aos casos de racismo sofridos pela Taís Araújo, a Jornalista Maju Coutinho e o Cantor Seu Jorge, percebeu-se que a penalização de tais crimes ainda tem muito que evoluir, não há rigidez na penalização quando se trata de crimes fundamentados pelo ódio a raça, a gênero, sexualidade e região.

The purpose of this study was to explore similarities and differences between special educator preparation in Ontario and in Mauritius through a comparative case study methodology. The cases are two practicing and experienced special educational needs (SEN) educators, one from each country, who are experts in special education teacher training programs in their respective country. Data were collected through semi-structured interviews and thematic analysis was used to analyse the qualitative data through deductive and inductive coding. Findings indicate major differences in teacher training opportunities, practicum aspects, and key challenges. On the other hand, limited technology integration and unsuccessful responses to COVID-19 disruption are similar features. Recommendations are provided including a call for increased efforts to develop and study emerging technologies to support special education training. The results of the study have implications for stakeholders and policy makers.

Authors: Majeed Zahid , Ul-Qayyam Zia
Published: December 2022

In Pakistan less than 1% of total differently able population have access to education and only 0.2% are in higher education. The reasons are many because of policies, accessibility, exclusion, facilities, equal opportunities, infrastructure and skilled faculty at the universities. In Pakistan Allama Iqbal Open University is the only university providing open and equal educational opportunities to all the disabled in Pakistan. Because of the blessing of Covid-19 higher education institutions of Pakistan are more open, accommodative and inclusive and providing opportunities to disabled students too. In this study the researchers interviewed more than 200 students graduated from AIOU and formal universities. The aim of this qualitative research was to determine their experiences of online education at AIOU and formal universities. Also, their perceptions of the relationship between inclusive educational environments and academic performance. The sample of the study was included students with hearing impairment, visual impairment and physically disabilities. The participants of the study indicated that disabilities presented concentration and scheduling challenges, the flexibility of online learning as well as participants' skills at self-accommodation and self-advocacy were instrumental in their academic performance/success. The study recommended that the online education at formal universities should be more supportive and accommodative online education environment. They further recommended formal universities with the help of AIOU should develop eContent (usability and accessibility), eAssessment and trained faculty to teach the disabled on online learning management system

Yeast and its derivatives are extensively utilized as feed additives in poultry industry owing to their desirable health and growth promoting effects. Exhaustive number of studies had reported positive effects of yeast based additives on growth, meat quality, immunity, antioxidant status, and gastrointestinal functions in poultry birds. Owing to their prebiotic/probiotic properties, they also play significant role in gut development and modulation of gut microbiome by favouring beneficial microbes while reducing colonization of pathogenic microbes by competitive exclusion. They also possess effective potential for binding of dietary toxins in addition to improving digestion and utilization of nutrients. Moreover, yeast based additives have exhibited desirable effects on humoral immunity by increasing serum immunoglobulin (Ig) A levels. These additives have been also used as immune adjuvants to boost innate immune response under any pathogenic challenges in birds. Due to their diverse biological activities, yeast products are potentially capable for immune hemostasis by mediating balance between pro- and anti-inflammatory activities. These unique properties of yeast based products make them promising feed additive to promote health and productivity leading to efficient poultry production. Yeast can be supplemented in poultry diets @ 5.0–10.0 g/kg of feed. Numerous studies had reported significant improvement in body weight gain (3 to 8%) and FCR (1.6 to 12%) in broilers in response to supplementation of yeast based additives. Moreover, yeast supplementation also improved hemoglobin (Hb g/dl) levels up to 2.59 to 6.62%, total protein (>0.69%) while reducing serum cholesterol (mg/dl) up to 3.68 to 13.38%. Despite the potential properties and beneficial effects, use of yeast and its derivatives as feed additives in poultry industry is not matching its inherent potential due to many reasons. This review aims to highlight the importance and potential role of yeast and its products as natural growth promoter to replace in feed antibiotics to address the issues of antibiotic residues and microbial resistance. This article provides insights on functional role of yeast based additives in poultry diets and their importance as commercially viable alternatives of antibiotic growth promoters in poultry feed industry.
