Arctic aquatic graminoid tundra responses to nutrient availability
Authors: Andresen Christian G. , Lougheed Vanessa L.
Published: April 2021

Abstract. Unraveling the environmental controls influencing Arctic tundra
productivity is paramount for advancing our predictive understanding of the
causes and consequences of warming in tundra ecosystems and associated
land–atmosphere feedbacks. This study focuses on aquatic emergent tundra
plants, which dominate productivity and methane fluxes in the Arctic coastal
plain of Alaska. In particular, we assessed how environmental nutrient
availability influences production of biomass and greenness in the dominant
aquatic tundra species: Arctophila fulva and Carex aquatilis. We sampled a total of 17 sites distributed across
the Barrow Peninsula and Atqasuk, Alaska, following a nutrient gradient that
ranged from sites with thermokarst slumping or urban runoff to sites with
relatively low nutrient inputs. Employing a multivariate analysis, we
explained the relationship of soil and water nutrients to plant leaf macro-
and micro-nutrients. Specifically, we identified soil phosphorus as the main
limiting nutrient factor given that it was the principal driver of
aboveground biomass (R2=0.34, p=0.002) and normalized difference
vegetation index (NDVI) (R2=0.47, p=0.002) in both species.
Plot-level spectral NDVI was a good predictor of leaf P content for both
species. We found long-term increases in N, P and Ca in C. aquatilis based on historical
leaf nutrient data from the 1970s of our study area. This study highlights the
importance of nutrient pools and mobilization between terrestrial–aquatic
systems and their potential influence on productivity and land–atmosphere
carbon balance. In addition, aquatic plant NDVI spectral responses to
nutrients can serve as landscape hot-spot and hot-moment indicators of
landscape biogeochemical heterogeneity associated with permafrost
degradation, nutrient leaching and availability.
Identification of wind turbine main shaft torsional loads from SCADA measurements using an inverse problem approach
Authors: Remigius W. Dheelibun , Natarajan Anand
Published: April 2021

Abstract. To assess the structural health and remaining useful life of a wind turbine within wind farms one would require site-specific dynamic quantities such as structural response and modal parameters. In this regard, a novel inverse problem-based methodology is proposed here to identify the dynamic quantities of the drive train main shaft, i.e., torsional displacement and coupled stiffness. As a model-based approach, an inverse problem of a mathematical model concerning the coupled shaft torsional dynamics with SCADA measurements as input is solved. It involves Tikhonov regularisation to smoothen the measurement noise and irregularities on the shaft torsional displacement obtained from measured rotor and generator speed. Subsequently, the regularised torsional displacement along with necessary SCADA measurements is used as an input for the mathematical model and a model-based system identification method called the collage method is employed to estimate the coupled torsional stiffness. It is also demonstrated that the estimated shaft torsional displacement and coupled stiffness can be used to identify the site-specific main shaft torsional loads. It is shown that the torsional loads estimated by the proposed methodology is in good agreement with the aeroelastic simulations of the Vestas V52 wind turbine. Upon successful verification, the proposed methodology is applied to the V52 turbine SCADA measurements to identify the site-specific main shaft torsional loads and damage equivalent load. Since the proposed methodology does not require a design basis or additional measurement sensors, it can be directly applied to wind turbines within a wind farm irrespective of their age.
Barriers to Adopting Electronic Commerce for Small and Medium-sized Enterprises in Emerging Economies
Authors: Nazir Muhammad Arsalan , Roomi Muhammad Azam
Published: April 2021

With the availability of the Internet as an Information and Communication Technology (ICT) tool, electronic commerce (e-commerce) has received much attention in many Western and developed countries. However, it has been given little attention in emerging economies, and therefore e-commerce adoption has been particularly difficult for Small and Medium-sized Enterprises (SMEs). The purpose of this review paper is to explore several types of barriers that influence the adoption of e-commerce by SMEs in emerging economies. An exhaustive review of the literature was conducted on the subject. It further evaluates and extends Tornatzky and Fleischer’s (1990) Technology-Organization-Environment (TOE) framework by adding a micro-level context - that of the ‘entrepreneurial (individual) characteristics of owner-managers’ to examine various contextual challenges SMEs face in adopting e-commerce in emerging economies. The paper examines a number of new dynamic and contextual barriers identified in the study, grouping them into four themes: technological, organizational, environmental and extended ‘entrepreneurial (individual) characteristics of owner-managers’. The paper sets up a new conceptual framework and has established a holistic view of contextual barrier themes for the coming years. In addition, this theoretical model provides us with the new barriers related to ‘entrepreneurial (individual) characteristics of owners/managers’ and ‘local business institutions in supporting e-commerce’ that influences the adoption of e-commerce by SMEs in emerging economies. Based on this extended framework, future areas of research can be determined, and owner-managers of SMEs, new entrepreneurs and government authorities in emerging economies will be able to identify emerging concepts in e-commerce.
Territorial expression of urban fear: the spread of gated communities in Lithuania
Authors: Balčaitė Simona
Published: April 2021

This article presents the analysis of the spread of gated communities in Lithuania considering the theoretical basis and the impact of ‘culture of fear’. The ‘urban fear’ is considered as a complex of anxieties that involves fear of changes, instability and disorder as well as non-acceptance of differences, diversity and the ‘others’. Those fears and the need for social control create the model of gated living, in which not only gated communities but also gated mentality plays an important role. Thus gated communities appear to be both the consequence and the reason of mental ‘gatedness’ as well as unsustainable development of modern cities, in which the demand for gating is produced by fear-creating media and real estate developers.
The study was made in suburban areas of three main Lithuanian cities, identifying gated communities and other fenced (but not guarded) neighbourhoods and housing developments. The features of their physical enclosure, security measures and community building were recorded. A total of 129 suburban gated communities and nearly 390 other fenced neighbourhoods were identified. The analysis of gated communities` spread revealed changes not only in the amount and territorial distribution but also in ‘gatedness’ of gated communities in Lithuania.

Published: April 2021

Observations and initial analysis of interplanetary scintillation data are briefly described in the framework of the program for the solar wind monitoring with the modernized LPI LPA radio telescope that started in 2014. The examples of detecting interplanetary coronal mass injections (ICME) and co-rotating interaction regions (СIR) of different-speed flows are presented. It is shown that in the first case, enhancements in the scintillation level in extended sounded regions of solar wind are observed 20–30 hours before the arrival of the disturbances to the Earth; in the second case, the evening and night scintillation level decrease is observed several days before the compressed region of disturbances comes to the Earth. These features are considered as a base of using interplanetary scintillation monitoring data for short-time space weather forecasting.

Authors: Ferone Georges , Crinon Jacques
Published: April 2021

Les réseaux connectés d’enseignants se sont fortement développés ces dernières années et ils se définissent aujourd’hui comme contribuant à la formation et du développement professionnel de leurs membres. Leurs effets diffèrent toutefois fortement selon le type de collectif et selon les individus. Cette étude concerne le réseau Twictée qui regroupe plusieurs centaines d’enseignants francophones de l’élémentaire et du collège mettant en œuvre un dispositif innovant d’enseignement de l’orthographe et échangeant à distance sur cet enseignement. L’analyse porte sur des entretiens menés avec dix-neuf enseignants sur deux années scolaires. Elle montre que le réseau Twictée peut être défini comme une communauté d’apprentissage professionnelle et elle met en évidence quatre profils de participants selon la nature et l’intensité de leur engagement. Les dynamiques de changement, quand elles existent, touchent surtout aux modes d’organisation pédagogique et à l’intégration du numérique dans les pratiques d’enseignement. Des changements identitaires se produisent chez les acteurs les plus engagés de la communauté.

Le quartier de Castro à San Francisco comme utopie contemporaine. “Somewhere over the rainbow”
Authors: Basural Idil
Published: April 2021

In search of a utopia in a real place, in which groups marginalized by society recreate a space, this article offers an analysis of the Castro neighborhood in San Francisco. This neighborhood inhabited by sexual minorities is an example not only of a utopian counter-space, but also of a resident identity based on an urban space, of an international LGBTQ+ community. First, a micro-history of Castro and the imaginary construction of the neighborhood through images, narratives, words, everything visual and discursive will show, the infrapolitics, the invisible structure of this resistance. In a second phase, the promises and conditions of the neighborhood will be examined in order to discuss the accessibility and credibility of this utopia. Based on Foucault’s concept of heterotopias, the principle of "a system of opening and closing" of this utopian space will be questioned through testimonies of the current inhabitants during the San Francisco Pride of 2019. This analysis of the history, structure and semiology of the neighborhood and its relationship to the outside world will allow us to question the possibility of a utopia that is feasible or achieved in today’s world.
Correlation of legal regulations on evidence and proof procedures with article 6 of the european convention on the protection of human rights and fundamental freedoms
Authors:   University of European Studies of Moldova, Cuciurcă Angela
Published: April 2021

Evidence and evidence are of particular importance in criminal proceedings, as, together with evidence, they are closely linked to the realization of the principle of finding out the truth, as well as to the fact that in most criminal cases there are problems related to evidence and means of proof. The legality of the evidence depends on the issuance of a decision to convict or acquit the person in a criminal trial. Legal regulations are closely correlated with the provisions of the Convention for the Protection of Human Rights and Fundamental Freedoms, in particular Article 6, the right to a fair trial. In this context, a criterion of applicability of this article in criminal matters lies in the nature of the procedure; the text refers to the right to be tried by a court, in the sense of court, which must decide on the merits of any accusation in this matter criminal law, and the merits of an accusation are based on conclusive, pertinent and useful evidence administered by means of evidence and evidence procedures provided by law.
Normative models for criminalizing the crime of falsifying evidence in the legislation of different states
Authors:   Ștefan cel Mare Police Academy, Piterschi Eugeniu
Published: April 2021

Crimes against justice established in the Criminal Code of the Republic of Moldova are the group of socially dangerous facts, which have negative consequences in court proceedings. One of these is the illegal action of falsifying the evidence, dislocated in two typical normative variants at art.310 of the Criminal Law of the Republic of Moldova. However, notwithstanding the fact that art.310 of the Criminal Code of the Republic of Moldova criminalizes the subject directly nominated in the normative manner, the latter is instituted succinctly and allows illegal actions in the category of false evidence to go unpunished. In this sense, we propose as a desideratum the realization of some comparative studies and the initiation of a rigorous proposal, in order to adjust the local normative framework in co-relation with the socially dangerous facts committed in the objective reality.

In the Republic of Moldova, the Internet has become the main information resource. This, we can appreciate that in comparison with providing a person with many advantages and opportunities, the Internet generates more and more legal problems. The main reason for this is violation of fundamental human rights, violation of the interests of society and the state. The articles provide arguments about the need to regulate the Internet, starting with the Constitution of the Republic of Moldova and ending with the current legislation. In the opinion of the authors, the right to the Internet should also be enshrined in a special law, which would provide for the conditions for access to the Internet, the obligations of service operators and users, restrictions and guarantees of responsible use of the Internet.

Published: April 2021

Four-dimensional education is a profound strategic dialogue about education. By questioning the often tacit and outdated agreement on what should be learned in school / university, the authors clearly demonstrate the systemic limitations that make up the curriculum. The analytical researches of the professional training curriculum indicate that the trainings must be within the established standards or exceed the limits in the direction of modernization, formation of the creative, innovative spirit. Four-dimensional training encourages both innovative ways of thinking. Disciplinary curricula should be based on the study of complex phenomena / processes, creating opportunities for interdisciplinary and trans disciplinary uses, as well as modern teaching methods, using the advantages of digital educational environments. The purpose of the investigation is to substantiate the priorities, objectives and educational principles advanced in terms of compliance with the structure and quality of professional graduates in accordance with the requirements of employers and the future labor market.

The importance of time management in the leading activity of educational institutions
Authors:   University of European Studies of Moldova, Cojocaru Aurelia
Published: April 2021

Among the revolutions that took place in the twentieth century, one of the most important was the managerial revolution. It was during this period that management became a separate field, developing intensely even today. Currently, in all developed countries, more attention is paid to the training of professional managers, because "the task of the leader is to be more and more efficient". The need to professionalize managerial activity in the field of education was realized in the West in the 60s and 70s of the twentieth century [1]. In the Republic of Moldova, this problem began to be addressed only in the 90s. Almost a hundred years ago, the author who founded the scientific management, Frederick Taylor, postulated the principle "Strict record of time and standardization of work" making a huge step towards increasing efficiency in the organization. Management means efficient and effective management of an activity. From this perspective, the manager cannot ensure the efficiency for the institution for which he is responsible if he does not know how to manage the resources efficiently. In addition, time is a precious, pretentious and irreversible economic resource: time is the rarest resource being irreplaceable but at the same time "unlimited", it is expensive, but it cannot be bought, stored, multiplied, and its loss cannot be assured either. By the largest insurance company in the world, so it cannot be "compensated", a source that can increase efficiency and profit, so that its good management is an essential skill [2].

Published: April 2021

The research aimed to study the correlation between the organizational climate and the job satisfaction of teachers. The link between climate and satisfaction is vital for success in teaching. The organizational climate is considered to be a relatively persistent set of perceptions of an organization's members about its internal environment and that influence their behavior. Job satisfaction is a positive emotional state that results from the employee's personal opinion of his work or work climate, a state of balance that the individual reaches when he responds to conscious or unconscious expectations and certain needs. The research results showed that teachers in the group of teachers-educators show high scores in terms of organizational climate in general and performance in particular. Teachers-educators are more performance-oriented, evaluated according to the achievement of objectives, cost reduction compared to other teachers. Psycho-pedagogical teachers are more satisfied with the quality of relations between employees, with reference to professional communication and collaboration, remuneration and promotion and have a higher degree of overall satisfaction. The organizational climate correlates with job satisfaction, so that the more favorable the organizational climate in the educational environment, the more satisfied the teachers will be.

Published: April 2021

This experiments conducted in 2019, to evaluate yield response of Okra (Abelmoschus esculentus, (L.) Moench) to attractiveness of colour sticky traps in relation to other population sampling methods and bio-pesticidal effects of Aqueous delonix seed extract on the flea beetles, Podagrica Spp. (Coleoptera: Chrysomelidae) in the Southern Guinea Savanna zone of Nigeria. Experimental design uses six coloured sticky traps as treatments in Randomized Complete Block Design (RCBD) and replicated three times. The design for efficacies of Bio-pesticides also in RCBD had four replications and five application rates, including a positive check and zero control as treatments. Yellow colour traps gave higher mean Podagrica Spp., catches but damage was higher in the white and purple traps, indicating other contributive factors affecting beetles feeding on Okra fruits. Higher precision was observed in hitting methods, when combined with colour reflectance. Yield of Okra fruits was optimum in all treatments, being higher in purple and least in white traps plants. Heavier fruits and least yield losses were in the least infected navy-blue treated plots. Agronomic performance was better in bio-pesticide treated Okra plants, but were not significant across different application rates with 57.30cm2 peak leave area at 20g/l, while mean fruit yield of 1007.00 was recorded at 15g/l Aqueous delonix seed application rate. Control had lowest mean fruit yield (780.00) with the highest fruits damage (11.33) per plot but heavier fruits recorded in the treated plants at 30g/l (66.75kg) over Cypermethrin (61.05kg). Pest population census showed significant (P < 0.05) decrease with increased application rates of the bio-pesticides. Hitting as sampling method was superior over sweep netting and was significantly different (P < 0.05) across the bio-pesticides application rates.
The Impact of the Covid-19 Pandemic on Akan Dying, Death and Mourning Rites
Authors: Boaheng Isaac
Published: April 2021

This study examines how the COVID-19 pandemic has affected Akan traditional rites related to dying, death and mourning. The study used a qualitative research approach (based on both primary and secondary sources) to examine Akan dying, death and mourning rites and selected critical issues arising due to the COVID-19 pandemic. Primary data were obtained from semi-structured interviews and participant observa¬tion whiles secondary data were obtained from books, journal articles and others. The study found that though COVID-19 health protocols have changed many Akan traditional rites related to dying, death and mourning, the Akan people still maintain their traditional beliefs about dying, death and mourning. Therefore, there is a high probability that changes that have taken place will be discarded as soon as the pandemic is over.

All thermal spray coatings are finally deposited on a rough and active grit-blasted surface of the job. But, available literatures are reporting splat and flattening behavior on a polished surface. There is a gap in thermal spraying to understand actual solidification on a rough surface. Therefore, in the present work an attempt has been made to study of splat formation of thermally sprayed copper onto grit-blasted rough surface. An optimization study is done to collect rounded/semi-rounded disk like splats to set spray parameters. Optimized parameters were also tested at four different gun traverse speeds to fabricate thin Cu coatings (30-50µm).

Products used in industry and marine applications are exposed to extreme environments like high heat, humidity, acidic or alkaline or hyper saline environment, UV and IR radiation. Metals with good corrosion and oxidation resistance may be used but are restricted to Ni and Cr alloys, titanium and super alloys etc., which are costly and have their limitations. Hence ceramic coatings on low cost metals may be an answer to this problem. Ceramics are inherently chemically inert, high temperature resistant, corrosion and oxidation resistant. Flame spraying of ceramics is a good and reliable method for applying ceramic coatings on metallic substrates with good bond strength (> 80 MPa) and 1% porosity. In this work, HVOF technique is applied to obtain 100 microns thick mullite coatings on MS substrates with a NiCr bond coat. Mullite has a high oxidation and corrosion resistance. It is chemically inert. It has high temperature resistance even at 2000 C. These properties are ideal for industrial components exposed to salty environments. Characterization studies like XRD, SEM/EDS, Corrosion tests using polarization technique, coating thickness and surface roughness have been studied and reported. A corrosion rate of 1.55 mm/ year has been achieved in a sea water environment.

Este trabalho investiga a trajetória das relações regionais que levaram à criação de blocos regionais como a UNASUL e a ALBA a partir dos anos 2000, e, sucessivamente, o impacto da mudança política regional em sua dinâmica. Tendo início a partir dos anos 2000, essas organizações internacionais se inserem na esteira do regionalismo chamado de Pós-hegemônico e da chamada “Onda Rosa”, buscando serem uma alternativa dos blocos anteriores por meio de uma integração também no âmbito social. Considerando que, em muitos momentos, também há um realinhamento dessas organizações tidas como alternativas à modelos regionais hegemônicos, assim como a capacidade de blocos reconhecidos até então como meramente econômicos, caso do Mercosul, também priorizarem em um certo momento uma agenda social, busca-se neste trabalho analisar os tipos de regionalismos na América do Sul, concomitante, ao espectro político de guinada à esquerda. Tem-se como pressuposto a ideia de que ciclos políticos influenciam o modelo de regionalismo a ser exercido. Para cumprir tais objetivos, será utilizada a técnica documental com pressuposto bibliográfico em torno da literatura das Relações Internacionais sobre regionalismo latino-americano e, na Ciência Política, a literatura sobre a “Onda Rosa” na América do Sul.
PERCEPÇÃO MACROECONÔMICA, FELICIDADE E IDEOLOGIA: UM ESTUDO DE CASO DO BRASIL (2010-2016)
Authors: Henrique Anderson
Published: April 2021

Qual é o efeito da percepção macroeconômica de inflação e desemprego sobre o nível de felicidade? O argumento principal deste trabalho é de que o efeito da percepção da inflação e do desemprego sobre o nível felicidade depende da ideologia política no Brasil. Portanto, testarei duas hipóteses de pesquisa: (1) quanto mais à esquerda estão os indivíduos, quando há percepção de desemprego, menor será o grau de felicidade dos eleitores e (2) quanto mais à direita estão os indivíduos, juntamente com a percepção de inflação, menor será o nível de felicidade. Metodologicamente, o desenho de pesquisa utiliza de estatística descritiva e Regressão Logística para analisar dados secundários do Latin American Public Opinion Project (LAPOP), no período de 2010 a 2016. Os resultados concluem que não há efeito estatisticamente significativo da percepção macroeconômica de inflação e desemprego, condicionado à ideologia, sobre o nível de felicidade dos eleitores no Brasil. Todavia, este estudo corrobora com os achados de opinião pública sobre a insuficiência da ideologia como balizador das escolhas e comportamentos políticos.

O presente trabalho parte da premissa de que a política fiscal é o ponto decisivo do Estado democrático capitalista, isto é, o exame das fontes de arrecadação tributária e a definição da alocação de tais recursos proporciona a compreensão realística do Estado -– inclusive de seus aspectos culturais e sociais. Partindo da premissa de que o pacote da austeridade pode reduzir direitos sociais, a presente pesquisa busca verificar a efetividade dos direitos constitucionalmente assegurados em tempos de austeridade. Para tanto, inicia-se pelo reconhecimento de que todos os direitos implicam um custo estatal para sua implementação. Evidenciando que a alocação de recursos, pelo Estado, compreende despesas públicas, tributação e concessão subsídios fiscais. Desse modo, indicam a aplicação de um programa de governo e revelam suas escolhas e prioridades. Logo após, passa-se ao exame da austeridade, sua estrutura, acoplamentos, fundamentos e objetivos. Por fim, examina-se em que medida o ajuste fiscal aplicado no Brasil se relaciona iniquidades de gênero, verificando seus impactos, no Brasil atual.
Work-Life Balance and Role Conflict among Academic Staff in the Middle East: A Review of Literature
Authors: Asfahani Ahmed M.
Published: April 2021

Family and work are fundamental aspects of life, and an individual must find a balance between both. Prioritizing one over the other can cause distress in one’s life. Every individual plays an important role in their work and non-work/personal life with the aim of fulfilling their needs, but it’s not always easy to find a balance, which may cause a conflict. The reasons behind this conflict vary according to different professional constraints such as working hours, work environment, nature of job, and interpersonal relations. Non-work and personal factors such as: marital status, number of children, home environment, age, gender, and location may also contribute. This paper aims to study the importance of work-life balance in reducing role conflict among academic staff in the Middle Eastern region.

Sheep farming is of great importance in generating income to smallholders in semi-arid areas worldwide. Gastrointestinal helminths cause important damage to the animals with poor welfare conditions, impacting in local economies. The objective of this work was to evaluate the FAMACHA method (FMC) in a herd of 60 Santa Inês from Paraíba, Brazil, and to compare the data from previous production years. In order to determine anemic sheep, FMC chart was used in biweekly evaluations for 12 months by trained personnel. Blood and fecal samples were collected monthly to determine packed cell volume (PCV), and parasite fecal egg count (FEC), respectively. The animals were divided into: dry, pregnant and lactating ewes, lambs and rams. Haemonchus was the predominant helminth genus (94.7%) during the whole year. There were up to 97% of success on the interpretation of FMC with 90 to 100% efficacy in the treatment decision. Among the 1356 evaluations, in only 40 (3%) were required deworming, being 27 during the rainy season and 13 during the long dry season. A statistically significant correlation (P < 0.01) was observed between FEC and PCV for the dry, lactating, and pregnant categories. The data reports a 94% reduction in deworming, with a greater need for anthelmintic use in lambs and lactating ewes (P < 0.05). Our data validates the use of FMC in Santa Inês sheep, which is considered a local resilient breed in the semi-arid region of Brazil. We recommend that animals should be examined during the rainy season to prevent most of the clinical problems.

This study was carried out in a randomized block design in a 2 x 2 factorial arrangement with the aim of evaluating the short-term changes in the plasma and milk fatty acid (FA) profiles of Holstein x Gyr cows (444±84 kg; 75±31 days in milk; 15.4±4.8 kg day-1 of milk) fed 600 g kg-1 DM chopped elephant grass-based diets supplemented with 45 g kg-1 DM sunflower oil (SO) for 21 days. Two types of SO were evaluated: high oleic/low linoleic acid (HO) and medium oleic/medium linoleic acid (MO). The concentrates containing SO were supplied separately from forage twice a day (TAD) or as part of a total mixed ration (TMR). Temporal changes were analyzed by mixed models (P < 0.05) using six, four and seven repeated measures over time for FA intake and the plasma and milk FA compositions, respectively. There was higher oleic acid intake in HO SO-fed cows, while higher linoleic and α-linolenic acid intake were observed in MO SO-fed cows. TADfed cows had a higher plasma vaccenic acid content than TMR-fed cows, while MO SO-fed cows had higher plasma vaccenic and rumenic acid contents than HO SO-fed cows. As a function of day, there were linear increases in oleic and linoleic acid intake; plasma contents of oleic, vaccenic and linoleic acids; and the milk fat content of linoleic acid, while quadratic effects were adjusted for the milk fat contents of palmitic, oleic, vaccenic and rumenic acids. In comparison with TMR-fed cows, the milk fat of TAD-fed cows produced between days 13 and 17 showed an FA profile that was more nutritionally desirable for human health, with lower contents of hypercholesterolemic FAs and higher contents of oleic, rumenic and vaccenic acids. Between days 15 and 16, the vaccenic and rumenic acid contents in the milk fat of MO SO-fed cows were 81% higher than those obtained from HO SO-fed cows, which on the 14th day had a 14% higher oleic acid content in milk fat. Lower milk fat levels of hypercholesterolemic FAs were produced between days 13 and 14 by cows fed both types of SO.
