1 - On Student Access and Equity in a Reforming University: Makerere in the 1990s and Beyond
Authors: C.Kwesiga Joy , Ahikire Josephine
Published: July 2023

This paper examines issues of access and equity in the context of the far-ranging reforms that have been taking place at Makerere University and in the Ugandan higher education system generally since the early 1990s. The analysis attempts to map out the contours of student access over time, outlining the major fault lines in student diversities which include, among others, location, class and gender, as well as the state (university) response to these diversities in the context of market based reforms. We argue that key to the reform programme was a reduction in the state’s financial commitment in higher education and the implementation of alternative financial strategies especially relating to the introduction of the private sponsorship programme in 1992. Private sponsorship greatly expanded the intake of fee-paying students, and the total number of students in higher education in Uganda has ex- panded enormously. However, these apparent gains in terms of access to higher education have been offset by lack of necessary investment in facilities, with result- ing problems of over-crowding, excessive teaching loads, large classes and falling standards. The analysis also interrogates the ways in which government/private dynamic plays out in the context of a highly fractured education system, dominated by urban-based schools, particularly located in the south of the country, and how the various affirmative actions measures have in a way, reproduced social and class privilege.
2 - The University as a Site of Knowledge: The Role of Basic Research
Authors: Chachage Chachage Seithy L.
Published: July 2023

This paper extrapolates from the tensions between the University of Dar es Salaam Academic Staff Assembly (UDASA) and the university administration to make a case for academic freedom in Tanzania in particular and Africa in general. It draws on two key statements on academic freedom in Africa – the Dar es Salaam Declara- tion on Academic Freedom and Social Responsibility of Academics (1990) and the Kampala Declaration on Intellectual Freedom and Social Responsibility (1991), to discuss the role of basic research in the university as a site for knowledge produc- tion. The paper argues that the quest for academic freedom is only meaningful if universities renew their commitment to the public good. Only by fulfilling the pub- lic trust as weavers of the social fabric and upholders of the highest ethical dimen- sions of human life can universities reclaim their position in society and the world at large.

Abstract
1 - Developing Contradictions: Diversity and the Future of the South African University
Authors: Kotecha Piyushi
Published: July 2023

The manner in which the contemporary university is represented evokes an ‘either/ or’ conceptualisation of the university as either staying loyal to the fundamentals of teaching, research and outreach, or a wholehearted participation in the neoliberalisation of higher education. This paper begins by questioning whether this dichotomy is as clear-cut as is suggested. It proceeds to examine the idea of a market-driven university as an Organisation for Economic Co-operation and De- velopment (OECD) construct in an attempt to highlight the very different context and challenges faced by a developing country like South Africa. At the most obvi- ous level, the objectives of the White Paper (1997) and the National Plan for Higher Education (2001) pointed to achieving both equity and efficiency simultaneously by increasing access to address apartheid’s legacy and increasing cost savings and streamlined functioning. This dual imperative placed on the South African univer- sity has the benefit of opening up the institution to a range of possibilities that are neither exclusively ivory tower nor entrepreneurial. The remainder of the paper intends to unpack what these roles, functions and identities could be for the future South African university.
3 - The Role of African Universities in the Intellectualisation of African Languages
Authors: Alexander Neville
Published: July 2023

Neo-colonial language policies deriving from decolonisation have entrenched not merely the dominance but, fatefully, the hegemony of the languages of the Euro- pean colonial powers, especially that of English, which is also driven by contempo- rary globalisation processes. The intellectual and political leadership of the conti- nent has succumbed, with very few exceptions, to the forces that prevail in the linguistic markets and is reaping what Bourdieu (1984) refers to as ‘the profits of distinction’. African poverty and economic inequality are to be eradicated, or even reduced, during the twenty-first century. One of the central but least discussed is- sues that have to be addressed is the language question which is linked to the im- peratives of the democratisation of modern African states, of increasing effi- ciency and labour productivity for economic development, and of promoting individual and social equilibrium, including the enhancement of self-confidence and creativity. A general policy of promoting language equity in multilingual Afri- can societies and of developing (‘modernising’ or elaborating) African languages in the context of overall national development policies will have to be followed sys- tematically over a period of at least two generations. In this paper, the author con- siders the historical and social dynamics of African languages in high status func- tions and proposes a series of steps that will facilitate the realisation for the updated and revised Language Plan of Action for Africa, formulated and adopted by the OAU almost twenty years ago. The essay gives pride of place in this process to the African Academy of Languages (ACALAN), which is fast becoming the major point of reference in the domain of language policies for the continent.
6 - Excess Beyond Excellence: The University Beyond the Balance Sheet
Authors: Kistner Ulrike
Published: July 2023

This paper argues that there is an excess beyond the talk of excellence, that the University in its present drive for commodification and corporatisation cannot com- prehend. In outlining the conditions and effects of this excess, I will look at the non- symmetrical relation that plays itself out in teaching and learning as one of the sites of ethical practices. The notions adduced to analyse this core relation are those of charisma, transference and sublimation. I will outline the forms of exchange at work in the sites of this relation and analyse their differentiations and transformations. In as much as the teaching–learning relation encapsulates what is demanded psycho- logically and politically of a modern subject in a democratic order, jeopardising it in the name of efficiency, cost-cutting and an instrumentalised relationship to la- bour and commodity markets, means striking not only at the core of university education, but at the psychic and political foundations of a democratic order itself.
3 - Private Provision, National Regulatory Systems and Quality Assurance: A Case Study of Transnational Providers in South Africa
Authors: Singh Mala , Lange Lis , Naidoo Prem
Published: July 2023

This paper looks into the emergence of transnational provision in South Africa in the context of the expansion of private higher education since the mid-1990s, and of the development of a national policy and regulatory framework that defines the role of higher education in the construction of a democratic society. The article analyses the characteristics of private and transnational provision of higher edu- cation and their impact in South Africa. It concludes with a reflection on the issues which developing countries may (need to) consider when constructing regu- latory frameworks for transnational provision.
4 - The Debate on Quality and the Private Surge: A Status Review of Private Universities and Colleges in Tanzania
Authors: Ishengoma Johnson M
Published: July 2023

While enrolments in private universities is still low in Tanzania, their number, however, is surging at an alarming rate raising critical questions about their aca- demic quality in terms of their course offerings and the qualifications of the aca- demic staff involved in teaching these programmes. Despite this surge in the sheer number of Tanzania private universities, public universities remain dominant in terms of enrolment. This paper (i) documents the hitherto-lacking critical infor- mation about private universities and university colleges in Tanzania, (ii) dis- cusses the implications of the surge and (iii) discusses the related issues of aca- demic quality.
9 - A Recent Echo: African Private Higher Education in an International Perspective
Authors: Levy Daniel C.
Published: July 2023

Africa is a very recent arrival to the world scene of rapidly growing private higher education but it strongly echoes historical and contemporary patterns elsewhere. This is evident in each major category of analysis that merits our attention. It is evident in causes of growth, forms of growth, types of institutions, finance, gov- ernance, status, and roles played. Of course, such a broad generalization must not obscure significant differences and variation. Regions have their own salient char- acteristics and Africa is no exception. However, one does not adequately under- stand African private higher education without seeing it in a global context. In turn, the understanding of global context is enriched by incorporating Africa in the analysis.

6 - The Private Higher Education Sector in Africa: Current Trends and Themes in Six Country Studies
Authors: Thaver Beverley
Published: July 2023

In Africa, the phenomenon of access to public higher education is under much pres- sure, and is harnessed by (among others) two privatization forces. These refer to the retreat of the state in terms of the provisioning of public higher education and the global economic rush which have culminated in both an increase in the number and to some extent the range of private higher education institutional types offering diverse course offerings. Although still small in scale and not representing a domi- nant share of higher education enrolment, their existence signals that they are meet- ing a social function of access in Africa, albeit limited. In light of this, there are traces of course offerings that suggest a small alignment with the economic and social needs of a modern society. Caught between the interstices of global eco- nomic capital and national societal functions, these institutions’ mandates and iden- tities are beginning to be stretched to meet modern imperatives. But, in this vortex, they are simultaneously hamstrung by certain sustainable systemic elements that go against the grain of the requirements for traditional higher education. Following this line of argument, the article begins with an overview of six country studies in Africa, including an outline of some of the discursive trends. It concludes by pro- viding a snapshot glimpse into the private higher education sector in South Africa.

Cet article ambitionne d’analyser les contestations des étudiants de l’Université de Ngaoundéré (de 1999 à 2002), la gestion de ces mouvements d’humeur et de revendications par les autorités administratives et leurs incidences sur la circula- tion des personnes et de leurs biens sur la route dite nationale n°1 qui dessert non seulement les provinces septentrionales du Nord Cameroun, mais aussi deux pays enclavés de la sous-région d’Afrique centrale, à savoir le Tchad et la République Centrafricaine. Deux contestations d’envergure ont eu lieu dans cette institution universitaire dont la gestion par les pouvoirs publics a entraîné des débordements d’étudiants qui ont érigé des barricades sur la nationale n°1 bloquant ainsi toute communication entre les provinces du Nord, de l’Extrême Nord du pays et les deux pays précités.

Can the Bologna Process Make the Move Faster towards the Development of an International Space for Higher Education where Africa would find its place?
Authors: Jean-Émile Charlier  , Sarah Croché
Published: July 2023

The Bologna Process is presented to the political and academic officials of Southern countries as the bearer of form constraints – the division of higher education studies into three main cycles (a bachelor’s, master’s and doctorate degree in respectively three, five, and eight years after the completion of upper secondary education) – and the calculation of the relative importance of subjects according to a credit mechanism. As unmenacing as it may look to decision-makers, reality is more complex. Form constraints soon turn into structural constraints that are only gradually revealed – mobility implies the transnational harmonization of academic timetables, the division of teachings and assessments into semesters, etc. The implementation of the ‘Bologna spirit’ also calls for interdependent universities whereas previously each only had to comply with their national constraints. In Africa, this interdependence is a strong asset for academic officials when they have to negotiate with their authorities. As it was the case in Europe, the solution to national problems will probably entail striking international agreements whose binding force will derive precisely from their international character.
Functional interdependence may enhance dialogue between academic officials. African universities should seize the opportunity of the call for dialogue as ex- pressed during the London summit in 2007 to have their qualifications certified according to international standards and thus weigh on the definition of quality that will bind the international space for higher education in the near future.

A Neglected Impediment to True Africanisation of African Higher Education Curricula: Same Agenda, Differential Fee Regimes
Authors: Chinedu. I. O. Okeke
Published: July 2023

This paper focuses on various international fee regimes within African universities and aims to sensitize debates around this highly neglected issue. My primary goal is not only to challenge arbitrary policy, but also to produce a useful sociological framework capable of enabling Africans to participate in their own educational development wherever they may choose to study. This paper targets African curriculum policy-makers and stakeholders and by focusing on the differential fee regimes, it is possible to show how such policy impinges upon current discourse on the Africanisation of higher education curriculum in very complex and subtle ways. Without disregarding recent efforts, however, I want to suggest that promoting an all-inclusive higher education environment within Africa without a single unified tuition policy negates all efforts toward an African curriculum agenda. An example is drawn from the thinking of the Bologna Process and the challenges such development presents to the African continent. The paper concludes that until differential policy regimes within African tertiary institutions are included on the agenda of various efforts toward the harmonization of African higher education, the journey towards a true Africanised, decolonized and all- inclusive education curricula for Africans may remain a mirage.
Liberté académique en question : contribution à la problématisation d’une notion à partir du cas estudiantin au Sénégal
Authors: Abdoulaye Guèye
Published: July 2023

La question de la liberté académique traverse l’histoire de l’institution universitaire. Elle se pose même encore aujourd’hui dans des pays de tradi- tion universitaire pluriséculaire, suscitant ainsi la production d’une littérature non négligeable. La caractéristique principale de cette production réside dans ce que j’appelle son « approche externaliste et politique ». Par cela, j’entends l’idée que, pour la majorité des chercheurs, poser la question de la liberté académique, c’est signifier une confrontation entre un groupe, la communauté des chercheurs et enseignants [academics], d’une part, et un autre extérieur à l’espace universitaire, et souvent défini par une identité politique : les autorités politiques nationales ou régionales. Ainsi les emprisonnements et les assassinats d’universitaires par des dirigeants nationaux ou des groupements politiques d’opposition (e.g. le FIS et le GIA en Algérie) sont suffisamment documentés. Cette approche est cependant un peu réductrice, bien qu’elle se justifie par la caractéristique autoritariste des régimes gouvernementaux qui voient le jour en Afrique. Telle quelle, cette approche offre une vision homogène de l’institution académique. Or, comme tout champ, l’institution universitaire se caractérise par une forte diversité, tant par les caractéristiques des acteurs qu’elle englobe que par les enjeux qui la traversent. Je voudrais dans cet article analyser la liberté académique du point de vue et à partir de l’expérience des étudiants.
Biosynthesis of Silver Nanoparticles and Their Applications
Authors: Nleonua Emmanuel Chile , Ben Amor Ilham , Zeghoud Soumeia , Hemmami Hadia
Published: July 2023

Recent developments in nanotechnology and nanoscience have improved methods for treating, preventing, and diagnosing a wide range of illnesses in many parts of living beings. Silver nanoparticles (Ag NPs) are among the most significant and intriguing metallic nanoparticles employed in several biological applications. To create Ag NPs, biomolecules from diverse microbial species and plant components have been researched as possible agents. Due to their physical orientation characteristics, and small size, these Ag NPs are widely employed and are said to have an impact on the performance of any other material that comes into touch with them. In addition, straightforward biological, physical, and chemical methods may be used to create Ag NPs. Due to their enhanced responsiveness to environmentally friendly technology for quantifiable synthesis, several developed nations have seen significant growth in the biosynthesis of Ag NPs. The biological method, however, is the approach to preparation that is most in demand since it is quicker, safer, less expensive, and more environmentally friendly than other techniques. In addition, the importance of Ag NPs is extensively examined in light of their numerous bioapplications, including those for antifungal, anti-inflammatory, antibacterial, Antiviral activity, Catalytic Activity, and anticancer medicines

Mesmo com a relevância na história da Computação, as mulheres ainda são minoria em cursos de graduação na área, consequentemente no mercado de trabalho e na academia. Nesse sentido, uma hipótese para o caso consiste no baixo índice de professoras que atuam na formação das discentes desses cursos nas universidades. O objetivo deste trabalho consiste em desenvolver um panorama da relação entre os gêneros dos professores da Área de Tecnologia da Informação (TI) que atuam nas Universidades Federais (UFs) da Região Centro-Oeste do Brasil. Nesse sentido, foram utilizados recursos de análise de dados e visualizações gráficas para coletar e avaliar as informações dos docentes, como: sexo biológico, titulação e universidade de atuação. Resultados indicam uma ampla diferença, cerca de três vezes maior, entre os homens e mulheres que atuam em cursos de TI nas UFs da região examinada.

Published: July 2023

Sr0.2Zn0.8TiO3 (SZT) ternary nanopowders of perovskite structure samples were prepared by conventional solid state reaction technique using ultra-pure metal oxide powders. SrCO3, ZnO and TiO2 powders were used as a source of Strontium, Zinc, and Titanium. The calcination temperature of the samples is 820 °C and sintered at different temperatures ranging from 850 °C to 1000 °C in conventional and microwave furnaces for 2 hours and 30 min., respectively. The synthesized nano-powders were characterized using XRD, SEM, XPS and their dielectric properties were studied by temperature dependent LCR meter. The dielectric constant increases with an increase in sintering temperature until 950 °C and it decreases with a further increase of frequency.
Aportación a la generación de umbrales adaptativos a partir de envolventes de sistemas con modelos aproximados : aplicación a la detección y diagnosis robusta de fallos en procesos industriales
Authors:   , Puig Cayuela Vicenç
Published: July 2023

El objetivo de la presente tesis es desarrollar un nuevo método de generación de umbrales adaptativos mediante la obtención de las respuestas temporales máxima y mínima a cada instante de tiempo, denominadas envolventes, a partir del modelo de un sistema con incertidumbre parmétrica de tipo intercalar en los parámetros. El nuevo algoritmo para la generación de envolventes presentado en esta tesis está basado en una ventana temporal deslizante y optimización. Una vez obtenidas las envolventes a partir del nuevo algoritmo de generación, se utilizarán para la detección robusta de fallos en procesos industriales.

La generación de envolventes para su posterior utilización como un umbral adaptativo en un método de detección y diagnóstico de fallo es todavía hoy un problema abierto. Se han propuesto muchos algoritmos para su generación pero ninguno de ellos consigue
garantizar la obtención de las envolventes correctas, entendiendo como correctas aquellas envolventes debidas a la incertidumbre presente en los parámetros del sistema y a la incertidumbre sobre los estados iniciales.

El método de generación de envolventes propuesto en esta tesis consigue generar las envolventes con la precisión deseada y con la incertidumbre acumulada por el proceso de generación de las envolventes acotada.

Los resultados y aportaciones más significativas que se han obtenido en esta tesis se enumeran a continuación:

. Nuevo algoritmo para la generación de envolventes basado en optimización y en el paradigma de las ventanas deslizantes.

. Determinación analítica y mediante simulaciones de la longitud de ventana óptima para obtener unas envolventes correctas.

. Demostración de que el nuevo algoritmo evita los problemas que padecen la mayoría de algoritmos de generación de envolventes: wrapping, multiincidencias, problemas de óptimos locales y el problema de propagación de la incertidumbre.
Pembersihan Sumur Gas Pada Produksi Gas Alam

Published: July 2023

Natural gas is an alternative energy source in current industrial development, so the demand for natural gas is increasing. The purpose of this research is to activate the function of the well so that it can resume production. The healthy cleaning method used is the clean-up method. This method is a method of removing pressure shut-off fluid in wells by using chokes of various sizes. The type of choke used is a fixed choke. The completeness of the data used is in the form of well testing data on the well, gas composition, and the amount of dead liquid included as a comparison. From the results of research on each well, it is known that in the Walanga#1 well, with 30 barrels of liquid raised and a pressure of 1,080 psi, Walanga#2, with 14 barrels of liquid lifted and a force of 1,080 psi, Walanga#3 with 38 barrels of liquid lifted and a pressure of 1,078 psi, Sampi-sampi # 1 with 80 barrels of liquid raised and a pressure of 1,050 psi. Therefore, based on the results of this study, it can be concluded that the dead liquid was not lifted to its maximum. Still, the pressure in the wells had reached its maximum value and returned to normal conditions so that the four wells could resume production.
Adaptive technologies in ultrasonic testing

Published: July 2023

The industry is continuously increasing the complexity of material geometries as a natural

outcome of innovation. This trend has been accompanied by the development of adaptive

inspection technologies that can overcome the inspection of irregular shapes. Latest advances

in electronic and software technologies have introduced a new paradigm in the Ultrasound

Testing (UT) method, going from a beamforming approach by mechanical and electronic

means (conventional UT and Phased-Array UT, respectively) to the generation of highresolution ultrasonic images in real-time by the so-called Full Matrix Capture (FMC) process

and its derived methods. This article focuses on the fundamentals of one of them, called

Adaptive Total Focusing Method (ATFM), used to solve the “last mile” in terms of ultrasonic

coupling and image quality in front of uncontrolled and complex surface variations.

"The focus of the contribution is the question of how the mode of fiction in the moderates emergence in the contact zone of games and narrative. In this zone - the residuum of the ambiguous, the non-actual, depragmatised - effects occur that assert themselves in paradoxes of understanding, action and evaluation. Ludic fiction - as play in narrative and narrative in play - confronts this problem through a cooperative 'modality management' that organises reality references through the principle of 'shared control'. In this way, the emergence of the of playful narration and narrated play becomes the task of interaction. "

Based on source material of approximately 200 medieval and early modern Bulgarian verbal charms, the study exmines the human agency in the belief system and practice of verbal charming. First, the article analyses the ritual performance, with its instructions, actions, paraphernalia, settings, human actors and proxemics. Then, the study deals with verbal amulets as major application and manifestation of verbal magic. Finally, the article investigates the ellusive figure of the charmer, via thorough collection of all data available, and offers synthesis of the various charming systems.
NORTHERN ENCOUNTERS: THE RUSSO-FINNISH BORDER AT THE BEGINNING OF THE TWENTIETH CENTURY IN A CROSS-REGIONAL COMPARATIVE PERSPECTIVE
Authors:   Independent Researcher, ERMOLAEVA OKSANA
Published: July 2023

This paper explores the connection between border making and order making projects and informal transborder practices and experiences in the geopolitically important sectors along contested Russian imperial/Soviet borders in the early twentieth century. In particular, the study examines how borders and controls were locally co-constructed at two different border strips of the Russo-Finnish border in the 1920s, while also conceptualizing the border as a site of informality and resistance. Findings, based on an array of previously unused historical sources, reveal that the cooperation patterns and rivalry between economic and military-political border control agencies in the early Soviet context differed in various regional frameworks, depending on the multiplicity of local factors. Civil, economic measures of border protection finally failed due to its inherent incompatibility with the increasing state pressures in a new, highly politicized context and a lack of financial and human resources. The paper demonstrates that the disintegration of the Russian empire was accompanied by enlivening of not only economic, but also generating new unique social and cultural exchanges at formerly ‘transparent’ borders. Novel cross-border networks and practices emerged around Soviet borders after 1917 in a radically transformed postimperial space, were all geared toward illicit transborder trade, but had their own unique specificity.
WAR AS AN EMBODIED AND EMOTIONAL EXPERIENCE: STORIES OF INTERNALLY DISPLACED WOMEN FROM ABKHAZIA
Authors:   Department of Social and Political Sciences, Tbilisi State University, Georgia, ARJEVANIDZE NARGIZA
Published: July 2023

This chapter focuses on the experiences of war and forced displacement in the stories of women internally displaced within Georgia, as a result of the armed conflict at the beginning of 1990s in Abkhazia. Based on the ethnographic research and life-story interviews with internally displaced women, this analysis seeks to understand how the IDPs have experienced the violent event, as well as its aftermath. Being consistent with scholars who reject the mind-body dichotomy and acknowledge embodied subjectivities of individuals affected by wars, this chapter argues that dramatic turning points in the lives of individuals affected by armed conflicts are experienced through emotions and feelings, as well as through bodies and bodily sensations reciprocally and in relation to each other.
Strange Vocations
Authors: Richards Amy Gilbert ,   Philosophy Documentation Center
Published: July 2023

Every vision of education relies on an inchoate anthropology—an implicit understanding of what it is to be human. This article seeks to bring the anthropologies implicit in modern and classical visions of education to light. Uncovering their respective understandings of freedom and disability reveals why we should accept the anthropology implicit in a classical vision of education. This understanding of anthropology through the lens of disability leads us to the heart of classical education by illuminating the strange vocations both of persons with disabilities and of classical educators. Further, it has important implications for the practices of classical schools in welcoming students with disabilities and learning differences.
An Epistemological Rationale for Classical Education
Authors: Fennell Jon , Simpson Timothy L. ,   Philosophy Documentation Center
Published: July 2023

The primary aim of this study is to fortify classical education against influential but dangerously constricted conceptions of assessment and accountability. This effort is supported by the strikingly insightful defender of liberal arts education, Harry S. Broudy, a preeminent voice in philosophy of education during the mid to late twentieth century. The article explores Broudy’s call for general or liberal education, highlighting the seminal epistemology of Michael Polanyi, upon which Broudy’s call stands. Exploration of Broudy’s epistemological rationale for classical education offers an occasion for reflection on the sort of person formed by such activity. The article will show that at the heart of comprehensive discussion of the ends, content, and methods of classical education, and manifest in the educational theory of Polanyi and Broudy, is a focus on shaping the moral imagination. Such shaping constitutes the character formation that is the fundamental objective of classical education.

Local governments in big cities of the Punjab (Pakistan) have moved animals out of cities in order to avoid severe difficulties of congestion, hygiene, safety and traffic. This move resulted in development of dairy colonies in the peri-urban areas of big urban centers. Peri-urban dairy colonies provide an important link between peripheries of big cities and urban centers through provision of milk and meat. This important peri-urban production system needs to be studied in detail in terms of collecting basic data about its economic viability, ascertaining major constraints and suggesting policy options for its improvement. Keeping the above in view, the present research investigated peri-urban dairy production system in third largest city of Pakistan i.e., Faisalabad during the year 2021. About sixty respondents from seven different peripheries of Faisalabad were chosen purposively and interviewed. The data collected from peri-urban milk producers was analyzed using descriptive statistics such as frequency distribution, percentages, averages, mean values and cross-tabulation. The study revealed that net income from livestock farming on overall basis was Rs.1108 per day while net income on farm size categories wise were Rs. 170, Rs. 910 and Rs. 2005 for small, medium and large livestock owners respectively. Major proportion of farmers (about 38 percent) from all three categories consider ed costly inputs as a major issue in peri-urban livestock farming followed by poor veterinary services (about 16 percent). Peri-urban dairy production system needs improvement in the form of various key factors such as proper feeding, availability of quality veterinary services, improved marketing of milk etc.

Agroforestry is a viable land-use option for utilizing salt affected soils which ensures the remunerative use of this valuable resource. A two years pot study was performed during 2018 to 2020 at Soil Salinity Research Institute, Pinid Bhattian to evaluate salinity tolerance of sapodilla fruit plant against different levels of salinity and sodicity. Treatments included were: T1 (control) = ECe , 1.32 dS/m + SAR 11.32, T2 = ECe , 8 dS/m + SAR 20 , T3 = ECe , 8 dS/m + SAR 25, T4 = ECe , 8 dS/m + SAR 30, T5 = ECe , 12 dS/m + SAR 20, T6 = ECe , 12 dS/m + SAR 25, T7 = ECe , 12 dS/m + SAR 30, T8 = ECe , 16 dS/m + SAR 20, T9 = ECe , 16 dS/m + SAR 25, T10 = ECe , 16 dS/m + SAR 30. No mortality was observed after one year of transplantation in any treatment. However, in second year it was observed that plants failed at higher level of salinity and sodicity in T9 (ECe 16 + SAR 30) and T10 (ECe 16 + SAR 35). Increasing levels of salinity and sodicity arrested the growth of sapodilla seedling and reduction of 62.31% in plant height, 59.70% in stem girth, 46.69% in leaves and 53.84% in branches over control was observed in T8 (ECe 16 dS/m + SAR 20. So, it was concluded that sapodilla seedlings can grow successfully at salinity and sodicity level of (ECe 16 dS/m + SAR 20).
Hydatid Cyst in Proximal Femur: A Case Report
Authors: Riaz Baloch Shahzaib
Published: July 2023

Hydatid cysts, caused by the larval stage of the tapeworm Echinococcus Granulosus, are rare in the musculoskeletal system. We present a unique case of a hydatid cyst found in the proximal femur / hip joint of a patient with an implanted hip prosthesis. A 75-years old male with a history of cemented Hemi-arthroplasty (Thompson prosthesis) presented with hip pain and limited (painful) range of motion of the hip. Radiologically osteolysis was appreciated, suggestive of implant loosening. Surgical intervention was done. Per-operative cystic lesions were found. Clinical diagnosis of Hydatid disease was made and the cysts were successfully treated with Hypertonic saline and albendazole. Histopathological examination confirmed the diagnosis of Hydatid cyst. This case highlights the importance of considering Hydatid cyst as a rare, differential diagnosis in patients even with a prosthetic joint, residing especially in endemic regions of the world, which would require multidisciplinary approach for their management.
Evolution equations on time-dependent Lebesgue spaces with variable exponents
Authors: Simsen Jacson
Published: July 2023

We extend the results in Kloeden-Simsen [CPAA 2014] to \(p(x,t)\)-Laplacian problems on time-dependent Lebesgue spaces withvariable exponents. We study the equation $$\displaylines{  \frac{\partial u_\lambda}{\partial t}(t)-\operatorname{div}\big(D_\lambda(t,x)|\nabla u_\lambda(t)|^{p(x,t)-2}\nabla  _\lambda(t)\big)+|u_\lambda(t)|^{p(x,t)-2}u_\lambda(t)  =B(t,u_\lambda(t)) }$$on a bounded smooth domain \(\Omega\) in \(\mathbb{R}^n\),\(n\geq 1\), with a homogeneous Neumann boundary condition, where the exponent \(p(\cdot)\in C(\bar{\Omega}\times [\tau,T],\mathbb{R}^+)\) satisfies \(\min p(x,t)>2\), and \(\lambda\in [0,\infty)\) is a parameter.
