Religious Tourism in Lahore: Case Study of Mosque Architecture under the Mughals
Authors: Ramzan Saira
Published: May 2024

The city of Lahore is well known for both its magnificent architecture and rich cultural legacy. Lahore saw a dramatic transition under the Mughal rule with the building of several famous mosques that continue to draw religious travelers from all over the world. This case study examines the possibilities for religious tourism keeping in view the Mughal era mosques of Lahore, while emphasizing their spiritual appeal and architectural value. The architectural integrity and beauty of these mosques require ongoing preservation and restoration efforts. Religious tourism in Lahore can boost the local economy by creating jobs, generating business revenue, and promoting cultural exchange, thus fostering interfaith dialogue and showcasing the Mughal mosque architecture. On the other hand, sustainable tourism practices, such as waste reduction, water and energy conservation, and responsible tourism behavior can mitigate the negative environmental and community impacts of religious tourism. The study highlights how crucial it is to protect and promote these locations in order to respect the Mughal architectural heritage, maintain religious customs, and improve the city's standing as a center for religious tourism.

Objectives. The aim of the study was to confirm the compliance of the mechanical and thermophysical properties of titanate-zirconate mineral-like matrices intended for immobilization of the rare-earth-actinide fraction of high-level waste (HLW) with pyrochlore structures (Nd2ZrTiO7) and orthorhombic titanate of rare earth elements (Nd4Ti9O24+TiO2) with the Russian requirements for the final forms of radioactive waste sent for disposal. With regard to fractionated radioactive waste, this type of matrix is preferable when compared with conservative aluminophosphate and borosilicate glasses. This is due to larger capacity, and a better level of chemical, thermal, and radiation resistance.

Methods. The synthesis of mineral-like matrices was carried out by remelting a granular precursor consisting of mineral-forming metal oxides and a solution imitating the rare earth-actinide fraction of HLW in an induction furnace with a cold crucible. The thermal diffusivity was determined by the laser flash method. The heat capacity of the matrix samples was measured by differential scanning calorimetry. Ultimate flexural and compressive strengths were determined using universal test machines. The elastic moduli (Young’s) were measured by the acoustic method. The temperature coefficients of linear expansion were determined using a high-temperature dilatometer.

Results. The ultimate strength of the matrices (Nd2ZrTiO7) and (Nd4Ti9O24+TiO2) was found to be 150–179 and 20.6–57.8 MPa in compression and bending respectively. Young’s moduli vary from 3.7 ∙ 107 to 2.15 ∙ 108 kN/m2. With an increase in temperature from 50 to 500°C, the values of thermal conductivity have a pronounced tendency to decrease from 1.71 to 0.91 W/(m∙K). The temperature coefficients of linear expansion increase from 6.96 ∙ 10−6 to 1.01 ∙ 10−5 K−1 in the same temperature range.

Conclusions. Comprehensive studies of titanate-zirconate mineral-like matrices show that their mechanical and thermal properties in certain cases significantly exceed the minimum requirements of regulatory documentation for the final forms of HLW.

The Brookfield relative viscosity method was used to evaluate the rheological properties of the resulting suspensions. The density of the resulting suspensions was measured by the hanging method using a calibrated pycnometer.

Results. The dependencies of the change in the particle size distribution after grinding in a bead mill were established. The viscosity of the suspensions was observed to increase following grinding. Common regularities of changes in the density of the considered suspensions were established.

Conclusions. The conducted studies showed that the physical and mechanical properties of suspensions are affected by the type and the filling ratio of the grinding media; the residence time of the suspension in the grinding chamber; the number of grinding operations; mill designs.
Trends in Malaysian Adolescents’ Mathematics Performance Across Two Decades: What Factors Matter?
Authors: Mohammadpour Ebrahim , Liou Pey-Yan , Ahmadi Parviz
Published: May 2024

Adolescents’ mathematics performance and its explanatory factors have been a crucial issue. However, literature focusing on adolescents in Malaysia is missing. Thus, this study investigates what individual and school factors have been associated with adolescents’ mathematics achievement over the last two decades. We examined six-wave data of Malaysia from the Trends in International Mathematics and Science Study (TIMSS). Multilevel modeling technique was employed for data composed of 5557, 5314, 4466, 5733, 9726, and 7065 eighth-grade students participating in 1999, 2003, 2007, 2011, 2015, and 2019, respectively. The results showed that 65.17%, 57.44%, 65.89%, 73.00%, 43.16%, and 61.69% of the total variance in mathematics achievement was due to school differences in these years. The findings also indicated that students with higher mathematics motivational beliefs scored higher. Students who more frequently spoke the language of the test at home achieved lower scores in the four waves of TIMSS; however, this trend changed in 2015 and 2019. Student educational aspiration emerged as a positive predictor of mathematics achievement in the last two assessments of TIMSS. Home educational resources and book ownership also significantly correlated with mathematics achievement. At the school level, teacher gender was negatively associated with achievement in all TIMSS waves except 2019. Students whom female teachers taught outperformed those whom male teachers taught. This longitudinal monitoring study of Malaysian students’ mathematics performance provides empirical evidence for local practices and advances literature based internationally.
Some issues on the Morphology of Yoruba comparatives and superlatives
Authors: Okebiorun Foluso Mary
Published: May 2024

Abstract
This paper provides a descriptive analysis of some issues concerning the morphology of Yorùbá comparatives and superlatives. Data were obtained from the researcher who is a native speaker of the language as well as from two adults (A man and a woman) in their fifties who are also native speakers of the language. I was able to describe and translate the data using my intuition as a native speaker of the language. The data were grouped into three categories, monosyllabic, disyllabic and trisyllabic adjectives. The implication of the analysis shows that in Yoruba, tone is a distinct marker of the comparative and the superlative. Also, the comparative and the superlative suffix reflects inflectional morphology, and can attach to any tone pattern of base adjectives that are monosyllabic, disyllabic, or trisyllabic. In addition, within the framework of construction morphology, the study provides a word construction schema to account for the comparative and the superlative forms.
medio-passive in Moroccan Arabic
Authors: Ech-Charfi Ahmed
Published: May 2024

This paper provides a preliminary semantic description of the verbal category referred to in modern grammar books of Moroccan Arabic as the “medio-passive” (e.g. Harrell 1962). This category is distinguished by the medio-passive marker ‘t-’ that is prefixed to a verb stem to express a variety of grammatical meanings. The origin of this prefix can be traced back to a similar morpheme in Forms V, VI and VII of the verb in Classical Arabic associated with reflexive, reciprocal, resultative and similar meanings. Most of these meanings still survive in the MA medio-passive form, which is also used to express the passive. Following the classification suggested by Kemmer (1993), this paper discusses four major uses of the medio-passive in MA. These are the passive (e.g. t-hǝrrǝs ‘to be broken’), the reciprocal (e.g. t-fahǝm ‘to get to mutual understanding’), the reflexive (e.g. t-ʕǝllǝm ‘to learn/teach oneself), and the middle (e.g. t-ʕǝʒʒǝb ‘to be surprised’) uses. The description is intended to serve as a basis for future comparison of the medio-passive in MA with its counterparts in other languages and the role diachronic change plays in shaping this grammatical category.
On Current Relevance in perfect and past constructions in Akan: The pragmatics
Authors: Ofori Seth Antwi
Published: May 2024

Abstract
This paper has the primary objective of establishing the pragmatic basis for concluding on a present perfect sentence as currently or continuously relevant and the simple past sentence as currently not relevant. This is an attempt to make the concept current relevance as used in relation to present perfect and simple past sentences in Akan determinate for Akan. Three to four formal tests were conducted to reach the following conclusions: The one primary focus or motivation for making a simple past or present perfect sentence in Akan is to indicate the validity/persistence or non-validity/non-persistence of a past event context as at the moment of speech; context is defined here as non-temporal in the form of some evidence of a past event in some space, and/or as temporal such as the period of time within which an event remains/is valid. In summary, in Akan a past event is currently relevant when context(s) of it in focus is/are current (i.e. persists or is valid as at the moment of speech) - present perfect; and currently not relevant when context(s) of it in focus is/are non-current (i.e. not persistent or valid as at the moment of speech) – simple past.

Published: May 2024

This article offers the first comprehensive study of relative constructions among the membersof the Western Serengeti (WS) group, a group of closely related Great Lakes Bantu languagevarieties spoken in the Mara region in northern Tanzania.The study has both a synchronic and a diachronic angle. First, we offer a systematicdescription of the various relativization types found in these varieties with regard to thephonological (prosodic) and (morpho-)syntactic traits of both subject and non-subjectrelativization. Next, we situate our findings within a historical-comparative framework, withparticular reference to Van de Velde’s (2021, forthcoming) Bantu Relative Agreement (BRA)Cycle. Linking the source of the main relative marker to the proximal demonstrative, we offera fine-grained reconstruction of its development into a relativizer.We propose that the WS relative constructions instantiate Stage 1b of the BRA cycle whilesimultaneously showing remnants of what is either the direct reflex of the relativeconstruction reconstructed for Proto-Bantu (Van de Velde forthcoming) or the final Stage 3bof an earlier cycle. In this endeavor we are able to zoom in to the processes at play at theturning point where an old and a new relative cycle intersect.
Solution of a Cauchy type problem for an integral equation of Volterra type with singular kernels, when the roots of the characteristic equations are complex conjugate
Authors: Rajabova Lutfya Nusratovna , Ahmadov Farvariddin Mufazalovich
Published: May 2024

In this paper, we study a two-dimensional Volterra type integral equation with a singularity and a logarithmic singularity for one variable and a strong singularity for another variable. The solution of an integral equation with special kernels in the case when the coefficients of the equation are interconnected is reduced to solving one-dimensional Volterra-type integral equations with special kernels. Using the connection of the considered integral equations with ordinary differential equations with singular coefficients, depending on the sign of the coefficients of the equation, explicit solutions of the studied two-dimensional integral equation are obtained. Depending on the roots of the characteristic equations and the sign of the equation parameters, explicit solutions of this integral equation are obtained. If the characteristic equation has complex conjugate roots, then the integral equation under study with special kernels has a single solution or explicit solutions contain two or four arbitrary functions. In the latter cases, the correct formulation has been clarified and explicit solutions of Cauchy-type problems have been obtained.

Provinsi Riau tercatat menempati urutan keenam terbawah dari 34 Provinsi di Indonesia berdasarkan nilai Indeks Ketahanan Pangan (IKP) tahun 2022. Meskipun nilai IKP Provinsi Riau rendah, tetapi Provinsi Riau memiliki peningkatan nilai IKP yang stabil tiap tahunnya. Ketahanan pangan dapat dilihat dari dua indikator yaitu akses fisik dan ekonomi yang berkaitan dengan Sustainable Development Goals (SDGs) yaitu pada tujuan ke-2. Tujuan penelitian ini adalah untuk melihat wilayah-wilayah yang memiliki nilai ketahanan pangan yang optimal dan tidak optimal berdasarkan kondisi akses fisik dan ekonomi. Penelitian ini menggunakan teknik analisis keberlanjutan yaitu Qualitative Comparative Analysis (QCA) dengan dibantu oleh perangkat lunak Tosmana. Populasi penelitian ini adalah 12 Kabupaten/Kota di Provinsi Riau. Hasil penelitian menunjukkan terdapat enam wilayah dengan ketahanan pangan optimal yaitu Dumai, Kepulauan Meranti, Kuantan Singingi, Pelalawan, Siak, dan Indragiri Hilir. Sementara itu, terdapat empat wilayah dengan ketahanan pangan tidak optimal yaitu Indragiri Hulu, Kampar, Rokan Hulu, dan Rokan Hilir. Kondisi tersebut disebabkan oleh perbedaan dari masing-masing wilayah yang memiliki aspek ketersediaan, aksesibilitas, dan kebermanfaatan yang direpresentasikan melalui indikator akses fisik dan ekonomi. Ketiga aspek tersebut menentukan kemampuan masyarakat untuk memperoleh dan memanfaatkan pangan secara cukup, aman, dan bergizi. Di sisi lain, program pemerintah daerah yang telah sukses dan belum efektif dalam implementasi peningkatan ketahanan pangan juga penyebab terhadap kondisi optimal dan tidak optimal.

Introduction. Silicon nitride is a highly promising material for fabrication of photonic integrated circuits (PICs). Plasma-enhanced chemical vapor deposition is a prospective method for large-scale industrial production of silicon nitride-based PICs. The disadvantage of this method, which limits its practical application, consists in high insertion losses in the telecommunication frequency band due to absorption on the Si–H and N–H bonds remaining from the film growth process. Thermal annealing is the most common method for breaking these bonds and reducing losses. Therefore, investigation of the impact of annealing on the optical properties of photonic integrated waveguides is an important research task.

Aim. To investigate the effect of annealing treatment on the optical properties of PICs based on the silicon nitride films with different thicknesses obtained by plasma-enhanced chemical vapor deposition.

Materials and methods. The work investigates the effect of annealing treatment on the optical properties of PICs based on the silicon nitride films with thicknesses of 200, 400 and 700 nm. To that end, the transmission characteristics of a set of test elements were measured using a high-definition component analyzer in the frequency range of 185…196 THz.

Results. Frequency dependencies of loss and coupling coefficients, as well as the group index before and after annealing were extracted from the measured transmission characteristics of the test elements. It was found that waveguides on a 200-nm-thick film exhibited higher losses in comparison with the waveguides on thicker films. The waveguides with cross sections of 900 × 400 and 900 × 700 nm2 demonstrate the losses below 5 dB in the frequency range of 185…190 THz. A rapid increase in losses due to absorption on the N–H bonds was observed at the frequencies above 190 THz. The work shows that thermal annealing reduces insertion losses across the frequency range from 185 to 196 THz. The adequacy of extracted optical parameters is confirmed by comparing theoretical and experimental transmission characteristics of the ring resonator.

Conclusion. The obtained results demonstrate that silicon nitride waveguides fabricated by the method of plasma-enhanced chemical vapor deposition require the stage of thermal annealing. Vacuum annealing at 600 °C for 30 min reduces insertion losses in the waveguides with cross sections of 900 × 400 and 900 × 700 nm2 down to 4 dB/cm in the frequency band from 185 to 196 THz.

The optimization of our wearable assist system (AS) to monitor isolated patients on isolation wards. A wearable chest patch and finger-worn pulse oximeter were used to estimate and transmit continuous temp, Heart Rate (HR), and peripheral blood Oxygen Saturation (SpO2) data from ambulatory patients on these isolation wards to nurse bays remote from these patients, with a view to minimizing the risk of infection for nursing staff. Our virtual High-Dependency Unit system used a secure web-based architecture and protocols to transmit the vital-sign data in real time from wireless Android tablet devices, operating as patient data collection devices by the bedside in the isolation rooms, into the clinician dashboard interface Available nremotely via any modern web- browser. Although Internet of Things buttons have seen some success as consumer products, little has been reported on their application in hospital systems. The system can be used to check the health condition of the patient by using three sensor such as heart beat sensor, temperature sensor and pressure sensor and also to monitor the saline droplet condition of patients in each patient’s bed in rural public hospital. Therefore, a particular interest is focused on continuous monitoring techniques. For continuous monitoring, Atmega328 microcontroller is used. In this case several sensor unit is considered. the sensed value is equal to normal value, it stops further process. Otherwise it sends control signals to patient via Actuator.

Published: May 2024

Introduction.  Torticollis, also known as crooked neck, is a contraction or contracture of the neck muscles that causes the head to tilt to one side. This is accompanied by rotation of the chin to the opposite side with flexion. The congenital form of torticollis usually appears within a few weeks of birth. The basis of diagnosis is clinical examination findings, and the mainstay of treatment is physical therapy. Surgical management is an option only when medical and physical treatments are not producing the desired results or for cosmetic reasons.
Case Report. A-11 year young girl came with a chief complaints of a tilted head to the right, she also had difficulty shaking her head and nodding and had an asymmetrical face. This has been experienced since birth.
Result. The patient underwent bipolar removal of the lower end of the sternocleidomastoideus muscle (SCM). The patient’s neck was extended with a sandbag, and then the patient’s head was turned toward the shoulder on the opposite, uninvolved side. First, the distal portion of the SCM was released by making a skin incision 3 to 5 cm long on the medial end of the clavicle, with consideration given to palpable fibrous bands, and then deepening the incision to the tendons of the sternal and clavicular attachments of the SCM. The tight band and muscle tendon were dissected to pass a right angle instrument posterior to the tendons and were then resected by electrocautery near the insertion site to the clavicle. The SCM was then carefully dissected and released near the bone, while checking the nearby nerves and vessels. Outcomes were assessed using the cervicalmandibular angle (CMA), calculated using the radiological head tilt, which was defined as the angle between the line crossing the upper border of the C7 vertebral body and another line connecting the lower border of the mandibular angle.
Conclusion. Release of the bipolar CMT in the patient in this study increased head tilt, leading to a better quality of life since surgery, and the patient adapted fairly well to her new neck position.

Semakin berkurangnya bahan bakar minyak menyebabkan timbulnya berbagai pemikiran bagaimana mengatasi permasalahan ini. Super fuel merupakan salah satu bahan bakar alternatif yang dapat digunakan pada berbagai mesin, salah satunya adalah mesin bensin pada generator set 4-langkah. Penelitian dilakukan dengan variasi jumlah bola lampu dan variasi bahan bakar. Bola lampu yang digunakan untuk pengujian yaitu lampu 100 Watt dengan variasi jumlah lampunya 2; 4; 6; 8; 10 dan 12. Sedangkan variasi bahan bakar untuk pengujian yaitu 100% premium; 95% premium + 5% super fuel; 90% premium + 10% super fuel; 85% premium + 15% super fuel. Berdasarkan analisis, diketahui bahwa performansi campuran super fuel mengalami penurunan torsi dan Specific Fuel Consumption (SFC). Tetapi emisi gas buang yang dihasilkan dengan menggunakan campuran super fuel, mampu mereduksi kandungan emisi gas buang beracun seperti karbon monoksida (CO), dan hidrokarbon (HC). Kadar sisa oksigen (O2) dari campuran super fuel mengalami penurunan sedangkan kadar karbon dioksida (CO2) mengalami peningkatan dibanding premium 100%.
