Error Propagation and Control in 2D and 3D Hybrid Seismic Wave Simulations for Box Tomography
Authors: Lyu Chao , Zhao Liang , Capdeville Yann , Wei Zigen
Published: April 2024

To enhance the local resolution of global waveform tomography models, particularly in areas of interest within the Earth’s deep structures, a higher resolution localized tomography approach (referred to as “box tomography”) is crucial for a more detailed understanding of the Earth’s internal structure and geodynamics. Because the small-scale features targeted by box tomography are finer than those in global reference models, distinct spatial meshes are necessary for global and local (hybrid) forward simulations. Within the spectral element method (SEM) framework, we employ the intrinsic Lagrangian spatial interpolation to compute and store hybrid inputs (displacement/potential) in the global numerical simulation. These hybrid inputs are subsequently imposed into the localized domain during the iterative box tomography. However, inaccurate spatial Lagrange interpolation can lead to imprecise hybrid inputs, and this error can propagate from the global simulation to the hybrid simulation. It is essential to quantitatively analyze this error propagation and control it to ensure the credibility of box tomography. We introduce a unique spatial window function into the conventional “direct discrete differentiation” hybrid method. When the local mesh and structure align with those in the global simulation, the synthetic hybrid waveforms match the global ones, serving as a reference for quantitatively assessing error propagation stemming from changes in the local spatial mesh during hybrid simulation. Significantly, the relative waveform error arising due to spatial Lagrange interpolation is around 5% when employing the traditional SEM with five Gauss–Lobatto–Legendre points per minimum wavelength in the 3D global simulation through SPECFEM3D_GLOBE. Ultimately, we achieve hybrid waveforms with an accuracy of about 1.5% by increasing the spectral elements by about 1.5 times in the standard global simulation.
Imaging the Sedimentary and Crustal Structure of the Luoyang Basin, Central China, Using a Dense Nodal Seismic Array
Authors: Wei Yunhao , Tian Xiaobo , Duan Yonghong , Wang Fuyun
Published: April 2024

The Luoyang basin lies in the southern margin of the North China block, separating the trans-North China orogen to the north and the Qinling-Dabie orogen to the south. Determining how the basin formed is important for understanding the history of the North China block and its evolution during the Mesozoic and Cenozoic times. Based on the teleseismic data recorded by a dense nodal seismic array, we used the receiver function method to image the sedimentary and crustal structures in the Luoyang basin. Common conversion point stacking images show that the Moho is at a depth of ∼35 km on the south and west sides and slightly uplifted to ∼30 km below the northeastern basin. Two sets of P-to-S conversions are imaged in the shallow crust, separating the near-surface sediments into consolidated, semiconsolidated, and unconsolidated layers. The top of the consolidated sedimentary layer is close to the surface at the southern basin and present at a depth of ∼2 km beneath the central basin, then deepens to a depth of ∼3 km below the northern basin. The discontinuous interface in the sediments indicates that the sedimentary layer was truncated by some blind north-dipping normal faults. The northeastward thinning crust, thickening sedimentary layers, and dipping normal faults together indicate that the Luoyang basin evolved in association with the deep crustal extension response to the lithospheric thinning of the North China block. By superimposing the deep crustal extension, we propose that the present-day landform of the Luoyang basin was also shaped by fluvial erosion at the surface, which was accompanied by the expansion of Yihe and Luohe riverbeds during the Quaternary.

Study of Intercultural-Intertextuality of Urban Linguistic Landscape—A Case Study of Jiahuifang in Xi’an
Authors: Zhang Kexin
Published: April 2024

Since China stepped into a new era, Xi’an has continuously built an open, modern and dynamic city image. In this background, the study of linguistic landscape, which is closely related to urban image building, has gradually attracted extensive attention. Taking Jiahuifang in Xi’an as an example, this paper analyzes the intercultural-intertextuality phenomena of Jiahuifang and explores the functions of linguistic landscape in urban space. It is found that there are more direct intertextuality and creative intertextuality signs, which reflects the high tolerance and openness of intercultural intertextuality; Nongovernmental intercultural intertextuality signs are more common, showing that shops are better at using foreign cultural symbols to participate in discourse space. Specifically, direct intertextuality realizes the recontextualization of different culture and foreign texts. Creative intertextuality creates new texts by mixing different codes to set up fashionable modern images. Interdiscursivity and multimodal intertextuality are less frequent, but the combination of various genres and nonlinguistic symbols is the exploration of multicultural integration. Accordingly, there are three major functions of intercultural intertextuality of linguistic landscape: realizing commercial value, uniting social groups and expressing the aspiration of internationalization. The suggestions for linguistic landscape construction lies in the balances between global and local, between government and non-government, and between tradition and modernity.
Maternal Diet and Foetal Growth: A Bio-Cultural Exploration
Authors: Nawathe Dr. Aarti Prasanna
Published: April 2024

Nutrition is influenced by biological and cultural factors. This study attempts to explore and evaluate dietary practices from a biocultural standpoint which aims to ascertain the nutritional pattern of expectant mothers. The foetus in the uterus is completely dependent on the nutrition provided by its mother. This nutrition is thought to be the most important intrauterine environmental element that modifies the expression of the foetal DNA, resulting in lifetime repercussions. The behaviour is known as "foetal programming," which has given rise to the contemporary notion of "foetal origin of adult disease." Women require a nutritious and safe diet not only during pregnancy, but also during their adolescence or prior to pregnancy, in order to build appropriate reserves for pregnancy. The goal here is to investigate nutrition in relation to its social setting. Nutritional anthropology seeks to understand the interplay of biological and social variables that influence the use of available food and the nutritional health of individuals 
and populations.

Fungal infections are now becoming more prevalent than bacterial in causing opportunistic and nosocomial infections. are among the most common invasive fungi that are seen in most patients with predisposing co-morbidities such as diabetes and hypertension. Therefore; identification of the species and antifungal susceptibility testing is essential for proper patient management as various species respond differently to antifungals and for the prevention of emergence of drug resistance.

isolated from different specimens were included in the study, speciation of the isolates was achieved by Vitek 2 automated machine and also with corn meal agar inoculation (CMA). The comparison of antifungal susceptibility testing was done by three different methods which included Vitek 2 systems, disk diffusion, and Micro-broth dilution methods. The antifungal susceptibility was tested for fluconazole and Amphotericin B.

A total of 50 isolates were randomly selected and speciated. Species-wise distribution showed s to be the most common one accounting for 34 (69%) followed by 12(24%) and 4 (12%) of them were . The overall resistance among these isolates was as follows: by micro –broth dilution fluconazole resistance to was 6% and to Amphotericin B was 8%. By disc diffusion, fluconazole resistance was 10%, Amphotericin B was 14%. With the Vitek 2 system, fluconazole and Amphotericin B showed resistance of 10% and 6% respectively.

Speciation and Antifungal susceptibility testing of solates are of great significance regardless of the specimen isolated from, which helps in the management and knowing the epidemiology of the susceptibility pattern of the . For this to become a reality a reliable, easy, and sensitive method of antifungal susceptibility needs to be used in every Microbiology laboratory as a routine practice.

Primitive neuroectodermal tumor of the prostate in a 64 years old man: An unusually late presentation
Authors: Singhai Atin , Sharma Akanksha , Mondal Diparati
Published: April 2024

Primitive neuroectodermal tumors (PNETs) are uncommon tumors that primarily affect young males. They are rarely seen in the prostate and occurence in an old age group is uncommon. We present a case of a 64-year-old male who presented with complaints of difficulty in passing urine for 1-year duration and on contrast-enhanced computed tomography showed an enlarged mass in the prostate with hypoattenuating areas. Serum prostatic specific antigen was mildly raised. Transurethral resection of prostate was done and histology showed clusters of round cells that expressed CD99. The patient underwent radical surgery for tumor resection. PNETs are tumors of soft tissue origin and generally affect the young age group. This case of PNET in the prostate is unusual for its site and age of presentation. In conclusion, while making a diverse diagnostic evaluation of aggressive prostate cancers, PNET should be taken into account.
Crystal associated colitis

Published: April 2024

Cation exchange resins such as sodium polystyrene sulfonate (Kayexalate) are used to treat life threatening hyperkalaemia caused due to electrolyte imbalances. These are usually administered as an enema, orally or via nasogastric tube along with a hypertonic mixture of sorbitol to prevent constipation. Although effective, it might lead to development of rare, but serious consequences involving the gastrointestinal tract. There is a need for awareness of the rare potential adverse effects associated with its widespread use. Here, we report 2 cases of colitis induced by the administration of sodium polystyrene sulfonate which were evidenced by luminal and impacted/adherent crystals of kayexalate causing mucosal injury.
Massive edema and fibromatosis of ovary: A rare case report
Authors: Johnson Thanka , Lakshmi K Abhishri
Published: April 2024

Ovarian lesions composed of spindle cells comprise a heterogeneous group; most are neoplastic, but several non-neoplastic lesions may be composed of spindle cells, including massive edema and fibromatosis and ovarian fibroma. Herein we discuss both these non- neoplastic entities as a differential diagnosis for our case of benign spindle cell lesion of ovary.

57-year-old post-menopausal female presented with abdominal pain, vomiting, constipation. Computed tomography showed, features of ovarian torsion. Staging laparotomy was done and a specimen of hysterectomy with bilateral salpingoophorectomy, was sent for histopathological examination. Sections from right ovary showed proliferation of spindle cells resembling stromal fibroblasts with large areas of edema and haemorrhage. Masson's trichrome show increased collagen deposition. The tube also shows changes secondary to torsion in the wall. Based on the above features, we made a diagnosis of benign spindle cell lesion of ovary with the differential diagnosis including massive edema and fibromatosis and fibroma of ovary. IHC for Inhibin was ordered which came negative. This confirmed the diagnosis of massive edema and fibromatosis.
Assessing the Effect of Fiscal Policies on the Gender Income Gap in Central America, Panama and the Dominican Republic

Published: April 2024

Persistent gender economic differences have led to an extensive amount of literature devoted to the gender wage gap. However, wages are only one component of income for women and men, and self-employment income, non-labour income, taxes, pensions, and benefits are mostly omitted from the analysis. In this paper we contribute to the small but growing literature of gendered fiscal incidence by studying the effect of taxes, social insurance contributions and benefits on the gender gaps in disposable income for five Central American countries: El Salvador, Costa Rica, Guatemala, Panama, and Dominican Republic. Our analysis makes use of tax-benefit microsimulation models based on representative household surveys for each country. We compare results for 2019 and for a year afterwards for each country to determine if there are differences due to the COVID-19 pandemic. Three sets of findings are worth highlighting. Firstly, the tax-benefit systems of Panama and Costa Rica have the largest redistributive effect measured by the size of taxes and benefits at the upper and lower part of the disposable income distribution respectively. Second, Costa Rica is the country that close the gender income gap the most, while in the other countries the tax benefit system does not have an important effect in this regard. Thirdly decomposition of the raw disposable income gender gap indicates that a) labour income is the biggest contributor to the gap in all countries and periods analyzed with a very minor role for tax-benefit instruments. b) almost half of the gap is explained by differences in attributes such as education, age, or geographical location, so a significant gap remains unexplained c) differences in employment rates between genders are less important than differences in remunerations.

Jubileusz 30-lecia istnienia czasopisma naukowego to okazja do podsumowania, przyjrzenia się rozwojowi i „dorastaniu” periodyku teologicznego, a także do spojrzenia z nadzieją na przyszłość. W artykule przedstawiono najpierw genezę czasopisma, zwracając uwagę na dwa czynniki, które się do niego przyczyniły, a więc funkcjonowania w Koszalinie Wyższego Seminarium Duchownego oraz Wyższego Instytutu Wiedzy Religijnej. Następnie przeglądowo opisane zostały zmiany wprowadzane na przestrzeni minionego trzydziestolecia. Były one związane ze zmianami w kolegium redakcyjnym, zmianami organizacyjnymi i zmianami afiliacji akademickich czy też dostosowywaniem czasopisma do ewoluujących standardów i oczekiwań wobec czasopism naukowych. W trzecim punkcie określone zostały podstawowe kierunki rozwoju czasopisma, a więc przede wszystkim dalsze umiędzynaradawianie czasopisma oraz jego aplikacja do ogólnoświatowych baz indeksujących, takich jak Web of Science czy Scopus.
The role of scientific journals in creating a scientific community

Published: April 2024

W perspektywie rozwoju nauki znaczenie mają nie tylko fakty naukowe, ale także środowisko, w którym dokonuje się przyrost wiedzy. Jednym z przejawów społecznego kontekstu uprawiania nauki jest istnienie czasopism naukowych, które powstawały jako reprezentacja potencjału konkretnego środowiska naukowego. Aktualne zmiany, zmierzające do próby wypracowania obiektywnych kryteriów oceny pracy naukowej, dotykają także procesu tworzenia czasopism naukowych. Związane są z tym szanse w postaci m.in. większego otwarcia na współpracę z innymi ośrodkami czy większej obiektywności oceny pracy naukowej. Towarzyszą temu jednak także zagrożenia, takie jak utrata lokalnej specyfiki danego czasopisma oraz depersonalizacja procesu wydawniczego.

Development of a mathematical model of the internal structure of a granular heat accumulator for launching a mono-fuel gas generator
Authors: Zrelov V. A. , Lykin A. Yu.
Published: April 2024

The issue of improving energy-mass characteristics is one of the most important ones in the development of gas generators for various purposes. In this regard, as part of the search for ways to use promising types of fuels, experimental studies of gas generators operating on composite mono-fuel based on nitrate esters were carried out. As a device initiating the combustion reaction, a granular self-heating heat accumulator was used, which was placed in a cylindrical combustion chamber. Experimental studies made it possible to reveal the features of a complex and multi-stage process of mono-fuel conversion occurring in the pore space of the gas generator combustion chamber on the surfaces of the granules and inside a complex system of channels consisting of elementary cells formed by these granules. In this case, the pore space of the heat accumulator is granular filling of mono-dispersed granules of a disordered structure. The task of the work described in the article was to create a mathematical description of granular filling of a disordered structure, solved in a two-dimensional formulation. The article proposes a method of transition from hexagonal stacking to conditionally ordered one that combines the compactness of hexagonal stacking and the ease of description of cubic stacking. The resulting stacking makes it possible to represent half of the frontal section of the granular heat accumulator in the form of a vertical flat layer with a given structure determined by porosity, granule diameter and dimensions of the combustion chamber – its length and diameter. The proposed approach for the transition from a disordered filling structure to a conditionally ordered structure made it possible to develop a mathematical model that describes the internal structure of the launch heat accumulator and determine the coordinates of the heat accumulator zones in which various stages of monopropellant conversion take place. This will allow us to proceed to the formation of a description of the working process of gas generators with a granular self-heating heat launch accumulator.

Published: April 2024

A generalized kinematic scheme of the installation of quadcopter motors is presented and its main advantages are described. In accordance with the scheme, a mathematical model of the kinematics of the quadcopter was developed. The model was implemented in the MatLab software environment. The presented mathematical expressions are used to calculate kinematic characteristics, such as the values of the thrust of the motors and the reverse effect of the motors on the body of the quadcopter. The comparison of the obtained data with the experimental characteristics showed a 5% deviation of the magnitude of the dependence of the thrust on the average value of the voltage on the motors and a 30% deviation of the magnitude of the dependence of the motor action on the thrust magnitude.
Affordances of Outdoor Risky Play in a Traditional and a Forest Kindergarten
Authors: Parczewska Teresa
Published: April 2024

The article aims to qualitatively examine the affordances of children’s risky play in two different Polish kindergartens, based on Gibson’s (1979) theory of affordances and extended work on this theory by other researchers (Heft,1988; Kyttä, 2002, 2004). Observations of risky play were made in a traditional facility, where children played in a traditional playground, and in a forest facility playground, where children played in nature, in an adventure forest playground (Bubble, 2002; Lee, 1999). The research methods included observation, semi-structured interviews with children, interviews with staff, and visual methods (video recordings using KB 176 mini personal recorders attached to children’s clothing in the forest kindergarten and the traditional kindergarten). The data showed the current affordances of risky play and its limitations. I found that the studied play environments (traditional and forest kindergarten) allow children to engage in risky activities, and the degree of staff permission to move freely is an important factor in actualizing the affordances. I have recognized that differences in the quality and characteristics of the two environments have important implications for the affordances of risky play. The natural playground in the forest facility provided a significantly higher degree of risk in children’s play activities.
Development and production of curly and iceberg lettuce under the influence of different types of mulch
Authors: Vialle Lucas , Coelho Evando Luiz , Eloi de Almeida Alves Rafaela
Published: April 2024

Lettuce is a plant that develops and is produced under the influence of climatic conditions, competition with weeds, pests, and diseases. One way of minimizing these effects on the crop is to use mulch, which can be of plastic or vegetable origin. This study aimed to evaluate the development and production of lettuce subjected to different types of mulch. The experimental design used was randomized blocks, with a factorial of 2×4 and four replications, with two cultivars—“Vera” for curly lettuce and “Delícia Americana” for iceberg lettuce—and four treatments—mulch with coffee husks, grass straw, black plastic and the control (no mulch)—, totaling 32 plots. Each experimental plot consisted of 20 plants, and only the six central plants were evaluated. The highest temperatures were recorded when using black plastic for covering, which also resulted in better weed suppression and higher means for plant height, number of healthy leaves, stem fresh mass, stem diameter, and commercial fresh mass. It was concluded that the Delícia Americana cultivar and the black plastic mulch provided the best growing conditions for the crop, with the best means for the variables studied.

Результаты. Эволюция использования искусственного интеллекта в образовании представлена как последовательность сменяющих друг друга трех моделей. В первой модели искусственный интеллект управляет когнитивным обучением, обучающиеся являются получателями его услуг; во второй модели обучающийся действует как партнер, искусственный интеллект используется для поддержки обучения; в третьей модели, обучающийся является лидером процесса, искусственный интеллект расширяет возможности обучения. Обосновано, что искусственный интеллект способствует персонализации обучения, созданию умных кампусов, установлению справедливости в образовании, расширяет возможности преподавателей, снижая их нагрузку. Выявлен ряд барьеров внедрения искусственного интеллекта в образование. Большинство разработок для обучения на базе искусственного интеллекта созданы без участия педагогов и используют бихевиористскую модель обучения. Педагоги не уделяют должного внимания потенциалу искусственного интеллекта, видят в нем угрозу своей занятости.

Внедрение инновационных технологий в индустрии гостеприимства приводит к трансформации методов работы гостиниц и других объектов размещения. Эти изменения связаны с необходимостью глубокого анализа гостиничных процессов и их оценки для осуществления на их базе процессной оптимизации. Применение инновационных подходов является путем к поддержанию высокого уровня сервиса и конкурентных преимуществ. Одним из способов достижения этих целей является концепция управления бизнес-процессами, которая широко используется и в других отраслях. В центре внимания этого управленческого подхода находятся бизнес-процессы, наборы скоординированных действий, выполняемых пользователями для достижения интеллектуальных целей и задач компании и их нотации, моделирование процессов. Основной целью данного исследования является изучение возможностей использования технологии BPM и реинжиниринга бизнес-процессов в гостинице и оценка их возможного влияния на организацию, предоставляющую услуги с интенсивным и динамичным взаимодействием человека с человеком. В статье описано моделирование бизнес-процессов и использование реинжиниринга в индустрии гостеприимства с акцентом на улучшение прямых телефонных продаж за счет применения CRM-системы. После моделирования текущего состояния выбранного процесса с использованием методологии ARIS тот же процесс был подвержен реинжинирингу посредством применения CRM-системы. Это внедрение сократило весь процесс (в основном – количество действий, необходимых для выполнения) и позволило сотруднику фронт-офиса быть более ориентированным на клиента. Автоматизация трудоемких процессов может сократить количество ошибок, вызванных человеческим фактором, и повысить конвертируемость запросов на бронирование и их общую ценность.

This study aims to identify the characteristics of effecive leadership and it influence on school effectiveness in the era of independent learning. To achieve these objectives, this study used an exploratory sequential mixed method. The initial phase on the research used qualitative methods, then the scond phase developed and subtantiated the initial findings widely using quantitative methods. A purposive sampling of 25 teachers was used to collect qualitative data. In the quantitative phase, a survey was conducted among 304 teachers in 59 public junior high schools in North Sumatra Province, Indonesia. The qualitative and quantitative research findings prove and support that transformational leadership is a force to realize school effectiveness in the era of independent learning. These characteristics of transformational leadership are (1) idealized influence, (2) inspirational motivation, (3) intellectual stimulation, and (4) individualized consideration. The idealized influence variable is the variable that most strongly influences school effectiveness by 41.1%; Individualized conciderance is the second most powerful variable affecting school effectiveness by 38.56%; inspiration motivation is the third most powerful variable affecting school effectiveness at 31.36%; intellectual stimulation is the fourth most powerful variable affecting school effectiveness by 17.22%.
Workshop on Open Access Publishing

The African Journal of Food, Agriculture, Nutrition and Development (AJFAND), is among the very few internationally renowned peer reviewed journals published in Africa. It was launched in August 2001, as the African Journal of Food and Nutritional Sciences (AJFNS) as a pilot project of the Rural Outreach Programme (ROP) by Hon Prof. Ruth Oniang’o. Its aim was to provide a platform, through which food and nutrition issues and information concerning Africa, and its unique problems could be effectively addressed and disseminated. A second objective of the journal was to provide a capacity building facility in scholarly publishing for budding African scholars. It became evident that these issues were also very closely linked to agriculture and human development in Africa. In recognition of this close linkage, the name of the journal was changed to African Journal of Food, Agriculture, Nutrition and Development (AJFAND).

An experiment of 35 days’ duration was designed using Completely Randomized Design to study broiler chicken growth rate in three different nocturnal lighting regimes, comprising, continuous darkness (0L: 12D), light (12:0D) and extended light (6L; 6D). The study was carried out at the Teaching and Research Farm of the Rivers State University of Science and Technology, Port Harcourt- Nigeria. A total of ninety unsexed broiler chickens were randomly distributed into the three lighting treatments at the end of three weeks of age. Each treatment replicated twice with 15 chickens per replicate. The broiler chickens were brooded together for 3 weeks on deep litter in an open-sided brooding house. Three 200 watts incandescent bulbs were used to provide a brooding temperature of 34-39°C. Black polythene sheets were used in covering the brooding pens to conserve heat and to maintain a uniform temperature. There was no light restriction during the brooding period. At the end of the third week, the birds were randomly distributed into three different lighting treatments of two replicates each with 15 birds per replicate. The three different lighting regimes were administered using a fluorescent tube between the hours of 6.00pm and 6.00am as follows: continuous light (12:0D), extended light (6L: 6D) and continuous darkness (0L: 12D). Black polythene materials were used to prevent light penetration from adjoining treatments during the night. Artificial light was provided by a 40 watt 'day light' fluorescent tube in each of the treatments. The parameters measured included body weight, body weight gain, daily feed consumption and feed conversion efficiency. The results obtained showed that there was no significant differences (P>0.05) in the weekly body weight and body weight gain in all the treatments. Also, feed conversion efficiency was not significantly different (P>5.0) in all the treatments. It was, therefore, concluded that since varying photoperiod has no significant effect on broiler growth rate, it will be wasteful for broiler farmers to incur additional cost of providing and /or extending the duration of light under similar geographical zones of this experiment. Therefore, artificial light is not recommended for a profitable broiler production.
Compositional and bacteriological quality of heat treated milk marketed in Namibia

Production of fresh farm milk in Namibia is low due to the arid climate that prevails in the country, low pasture availability and a high milk demand. This scenario has forced Namibia to import dairy products to meet its needs from neighbouring South Africa, South America and Europe. Namibia imports different brands of fresh full cream milk including Parmalat, Clover, Super milk to add on to its own brands such as Namdairies, UNAM milk and others from private and commercial farms in bulk or in plastic sachets and bottles. Generally, milk quality is determined by its safety, shelf life and nutrition. The presence of different brands of milk makes it difficult for milk consumers in Namibia to choose the brand they would prefer including assessing their value for money. The aim of the project was to determine the quality of full cream milk brands marketed in Namibia by assessing their proximate composition, titratable acidity, pH, protein stability, total plate count and Coliform bacteria as indicator bacteria for the presence of pathogens, using standard dairy procedures and AOAC methods. The results of the study indicated that all imported brands of pasteurised full cream milk in Namibia were not significantly different from each other and were safe and stable, and nutritionally of good quality. They were practically the same in composition and bacteriological quality. Butterfat ranged from 3.4 to 3.7%, density from 1.029 to 1.032g/cm3 , total solids from 12.3 to 13.0%, solids-not-fat from 8.6 to 9.7%, moisture content from 87.10 to 87.70%, acidity as lactic acid from 0.15 to 0.17% and pH from 6.4 to 6.7. The total plate count (TPC) ranged from 0 to 40 cfu/cm3 and there were no Coliform bacteria found in all the brands. The local products were not statistically different in composition from imported brands, with fat ranging from 3.3 to 3.7%, density from 1.029-1.032g/cm3 , TS from 12.3-12.9% and SNF from 8.6-9.4% though they were not standardized but heat treated. The total aerobic counts and Coliforms were the same as those of imported milk brands. The statistical analysis showed that there were no significant differences at p<0.05 among the brands and between the brands of the imported and local milk in Namibia as they were all within the South African Standard Specifications. All the brands were, however, regarded as good, stable and safe for consumption.
