Authors: Belokonev Sergei Yu. , Kapshina Anna V.
Published: July 2022

The purpose of this article is to identify the attitude of social media users to the elections to the State Duma in 2021. The research is based on the approaches of leading researchers of political behavior (M. Olson, M. Lipset, Ch. Tilly), as well as domestic scientists who described the trends of political development of modern societies in the context of digital transformation (V.D. Nechaev, S.Yu. Belokonev). The authors applied structural and functional approaches, as well as the method of frames (I.A. Hoffman) and techniques of social-media predictive analytics. The authors conclude that research of the attitude of social media users to elections is quite relevant, especially in the context of the influence of the Internet space on the course and results of election campaigns. The proposed methodology for assessing the degree of public confidence in elections requires further research.
Structural and Semiotic Features of the Virtual Narrative in Immersive RIA.Lab Projects
Authors: Samartsev Oleg R. , Latenkova Vera M. , Sleptsov Nikolai A.
Published: July 2022

The article examines the semiotic features of the virtual narrative in the projects of RIA.Lab platform of the leading Russian news agency “Russia Today”. The aim is to analyze the structural, linguistic and iconic elements of the virtual narrative in relation to the projects of immersive journalism, highlighting their features, taking into account the multimodal nature of virtual reality and the simulative aspect of the sign system of immersive works. Virtual space is not only a narrative environment with special topos, chronotope and other narrative elements, but is itself a semiotic element, participating in the process of semiosis, the space of virtual “language game”. The thesis is put forward that VR, being an element of the multimodal information and communication universe, contains in its structure other modalities (TV, radio, cinema, print formats), and is multidimensional, a kind of “modus in modus”. The thesis on the priority of the modeling approach to the creation of immersive mass-media content over the simulative one and the necessity of observing the balance between modeling and simulation in immersive journalism are discussed. The specifics of conventional conditions of interpretation of simulacra signs in virtual space, which depend on the degree of their identity to the signs of real reality and the “rules of the virtual game”, set by the authors, are outlined. The directions of increasing the pragmatic efficiency of virtual narrative through the variability of its affords, the use of emphases, haptics (tactile experience) and other means of VR are outlined.

Syed Muhammad Naquib al-Attas’ Exposition on the Concept of Ethics
Authors: Hidayatullah Elit Ave , Arif Syamsuddin
Published: July 2022

Syed Muhammad Naquib al-Attas, is a prominent Malay thinker who has promoted Islamization of present-day knowledge as a solution for the dilemma of Muslims. With that, he has also developed his original thought in various fields. His thought in the field of ethics, the content of adab, the central concept in his system of thought, and the essential teaching of Islam, is hardly elaborated. Thanks to that, it seems crucial to look into his view on ethical norms – its basis and principles – in such a way that his Islamization of ethics by means of infusing worldview of Islam into universal concept of ethics – a concept whose definition is universal, because its element can be found in any specific definition belonging to any worldview – can be known subsequently. Theory of Islamization of present-day knowledge – isolation and infusion process – is used for analyzing al-Attas’ view on ethical norms and theory of transparent worldview is applied also for analyzing his Islamization of ethics. Finally, according to al-Attas, the basis of ethics is religion approved by sound reason, knowledge, and the freedom of the will, whereas its principles are self-perfection, freedom, true faith and knowledge, happiness, and individual contract. As for his Islamized concept of ethics, it is a permanent attitude, action, assertion, and consideration belonging to spiritual aspect of man in his relation to his self, God, society, and state.
The Existence and the Challenges of Sufi Literature in Indonesia
Authors: iraj Fuad Mahbub , Arif Ridwan , Syadli M. , Amril Amril
Published: July 2022

The article is aimed at elaborating on the challenges of Sufi literature in Indonesia. This research is library research using a historical approach to obtain data and conducting content analysis. This research shows that Sufi literary treasures are the largest and most important part of the Islamic literature treasury. Sufi poets are not only pioneers in the revival of national literature in their countries, but they are also pioneers of the rise of the Islamic world. Sufis did not write mystical and transcendental works which are individualistic in nature. Their works are also associated with a social life that appeared in political allegory and literary whit history patterns. Sufism has influenced Indonesian literature since the early era of the spread of Islam in the Archipelago, i.e., in the 13th century. The emergence and development of Sufi literature in Indonesia is a direct impact on the swift process of Islamization, in which among the main actors are saints, scholars, teachers, and Sufi scholars. The works of the 16th-18th centuries have their position in the overall history of Islamic intellectuals in Indonesia. There are many important aspects in these works, especially those related to the way of life, the picture of the world (weltanschauung), and the value system of society. Even these Sufi works influence modern Indonesian literature. The existence of Sufi literature in Indonesia in this modern era is being challenged. The technical issues such as difficulty in obtaining theory and material resources, as well as references for Islamic aesthetics, literature, and culture, were often propounded as a reason for the less attention to the study of Sufi literature. In reality, the real reason is not purely technical; it is caused by the domination of Western theory in their minds, especially from the philosophy of neo-positivism also there is an assumption that non-Western theory has never grown the relevant theory of literary and aesthetics.

Authors: (Corresponding Author) Azlizan Mat Enh , Mansor Suffian , Abd. Razak Mohamad Rodzi
Published: July 2022

The intervention of the great powers in the Bosnian-Herzegovina conflict of 1875-1878 led the Turkish government to sign the Treaty of Berlin of 1878. One of the terms of the Treaty of Berlin was to put the administration of Bosnian-Herzegovina under the auspices of the mandate of the Austrian-Hungarian government. From this point onwards, the migration process in Bosnia-Herzegovina is reflected in its population, especially Muslims. This article examines the implications of the Treaty of Berlin on issues that led to the emigration of Muslims from Bosnia-Herzegovina to other regions of the Turkish Empire before the outbreak of World War 1. The analysis of primary data was used on the British records from its embassy in Bosnia- Herzegovina. The study found that religious issue was a crucial factor in the migration process happened in Bosnia-Herzegovina. The migration process intensified after Bosnia-Herzegovina was formally announced to be put under the Austrian-Hungarian administration in 1908.
Predicament of English Translation Dilemma in Academia: An Analysis on Selected Scriptures and Traditional Books
Authors: Yaacob Solehah
Published: July 2022

Translation is a tool of knowledge transferring an original language to another language. In other words, it is the process of converting the written word from one language into another language in a way that is culturally and linguistically appropriate so it can be understood. There are, however, challenges in translation which include knowing about a variety of features such as the language structure which differs between languages. The combination between the meaning and the written words in the original text has to be interpreted carefully in order to be translated accurately. Unfortunately, some translated works do not comply with the original one. Therefore, to address the problem above, the research attempts to highlight two types of critical translations in the academia: The Scriptures and the Traditional Arabic books through analytic and critical approaches. This paper focuses on an analytical study on some translations from the Bible and Arabic Traditional books with attempt to review and revisit some issues which are related to religion and beliefs as a starting point to the dilemma of translation.

Authors: Mohamad Noor Mohamad Muzammil
Published: July 2022

This article discusses scholars’ views on Muhammad Natsir’s thoughts. He was one of the prominent political figures and thinkers since the colonial period in Indonesia. As an Indonesia nationalist and political-religious activist, he did not cooperate with the Dutch in pursuit of Indonesia’s independence. Research papers on Natsir’s thoughts and struggles are often penned by local scholars and political-religious writers from that country, including Malaysian authors. This research utilized qualitative approach by conducting analysis through the libraries in Indonesia and Malaysia. Most of the article reviews was conducted through academic study of and general reading on Natsir, especially by Mestika Zed, Deliar Noer and Nurcholis Madjid. Besides that, writing on Natsir’s thoughts and activism was also written by Malaysian scholars such as Anwar Ibrahim, Siddiq Fadhil, Fadhlullah Jamil and Sidek Baba. Hence, the findings of this article attempts to identify the views of these scholars on Natsir’s thoughts and struggles in the political-religious and Indonesian nationalism against the colonial power. This paper also discusses scholars’ views on the contradiction of his political thoughts with Sukarno.

Authors: Lemos Jr Urbano , Gosciola Vicente
Published: July 2022

O estudo parte do uso dos sinos na China no ano 3000 a.C. e mostra como eles foram sendo incorporados à civilização europeia ainda na Idade Média. A partir do livro A História do Mundo em 100 Objetos, de Neil MacGregor, diretor do British Museum, o artigo objetiva mostrar a presença dos sinos e dos sineiros em significativos momentos da história. Em solo brasileiro, a pesquisa retrata a utilização do sino a partir da colonização do país, além de debater as influências culturais na execução dos sons dos sinos ao longo do tempo. O artigo se ampara nos historiadores Le Goff (2016) e Reis (2006), além de recorrer ao sociólogo Halbwachs (1990) para tratar sobre memória coletiva. Ao final, conclui-se que a representatividade dos sinos estão presentes em diversos momentos históricos. Na atualidade, eles se fazem presente pela importância cultural e relevância em manter essa tradição de forma coletiva.

Narrativas Visuais de Lunara: Fotografia, Arte e Relações Culturais no Início Século XX
Authors: Bujes Stumvoll Denise
Published: July 2022

Este artigo aborda as aproximações da fotografia com a arte em Porto Alegre na transição para o século XX, tendo como foco a “fotografia artística” de Luiz doNascimento Ramos (1864 - 1937), Lunara, fotógrafo amador da Belle Époque. O ponto principal da análise proposta é o álbum intitulado Vistas de Porto Alegre -Photographias Artísticas, produzido pelos Editores Krahe & Cia, provavelmente na década de 1900, com 20 imagens originais assinadas por Lunara. O álbum propõe narrativas visuais singulares sobre a cidade, ao refletir a trajetória poética de Lunara tanto na escritura, como na produção de suas imagens, nas quais somos conduzidos por um olhar sensível às transformações do seu tempo. Assim como aos lugares e às pessoas que ali viviam como se interessasse produzir uma metáfora da marginalidade social e cultural revelando o que geralmente ficava à sombra da memória visual da modernidade na paisagem urbana.
Corpos e existências: vidas não passíveis de luto
Authors: Mantovani Giovanna Liz Oliveira , Da Silva Vanilson Oliveira , Bernardes Anita Guazzelli
Published: July 2022

O objetivo deste artigo é refletir sobre a relação entre políticas sociais e performances dos corpos em termos de governo das vidas. O que interessa a esta discussão é percorrer um campo de problematização dessa articulação – políticas sociais e corpos – a partir da emergência da atual crise sanitária, causada pela pandemia de COVID-19. Essa problematização focaliza os efeitos sociais nas relações de governo dos corpos dentro de uma racionalidade de colonialidade e de racismo, ou seja, queremos pensar certas linhas de governo das vidas que se intensificam em formas de abandono, tornando-as não passíveis de luto. Para tanto, tomaremos duas performances de corpos em nossa atualidade – mulheres em situação de violência e usuários de drogas em situação de rua –, na medida em que ambas indicam mecanismos distintos de regulação de corpos e formas de abandono das vidas.

Presentación del Dossier de Historia Ambiental
Authors: Victoria Mena Carlos , Mora Pacheco Katherinne
Published: July 2022

En 1989 Augusto Ángel Maya uno de los pioneros de los estudios ambientales en Colombia, advertía sobre el retardo del método histórico para dejarse interrogar por la problemática ambiental. Al abogar por la “necesidad de una historia ambiental” criticaba que la vieja racionalidad desligaba el acontecer social de sus entornosnaturales y que el paisaje significa la raíz explicativa de la actividad social y simbólica. Desde entonces sus reflexiones se han tranformado en tierra fértil para una disciplina que sin mayores aspavientos ha venido labrando un nuevo escenario de estudios y reflexiones sobre las relaciones críticas pasado-presente-futuro en el contexto de unas condiciones socioambientales cada vez más apremiantes para la humanidad y en especial para los sectores más vulnerables de la sociedad.
Este dossier se inscribe justamente en la respuesta a las demandas y reclamos de Ángel Maya en la medida en que presenta a los lectores los resultados de investigaciones en el campo de la historia ambiental desde el punto de vista temático y metodológico, como la prueba que su acogida no es una moda ni un capricho aupado por las amenazas del Cambio Climático ni del Covid 19. Por el contrario, es la prueba que hoy la historia ambiental tiene un lugar cada vez más acertivo en medio de las nuevas historiografías que irrumpen en el ambito académico y ciudadano, como acicate de las desventuras del progreso, los conflictos y las enseñanzas de generaciones pretéritas. No solo se trata de la “narrativa que emerge de la naturaleza vencida”, como afirma uno de los autores, es tan bien la posibilidad de traer al presente los arreglos que distintas sociedades pactaron para sobrevivir.

Genome scan of landrace populations of the self-fertilizing crop species rice, collected across time, revealed climate changes' selective footprints in the genes network regulating flowering time.
Authors: AHMADI Nourollah , Barry Mamadou , Frouin Julien , Navascués Miguel , Touré Mamadou
Published: July 2022

Analysis of the genetic bases of adaptation to climate changes are often
conducted on natural populations. We report here on a study based on
diachronic sampling (1980 & 2010) of the self-fertilising crop species,
Oryza sativa (Asian rice) and Oryza glaberrima (African rice), in the
tropical forest and the Sudanian savannah of West Africa. First, using
historical meteorological data we confirmed changes in temperatures
(+1°C on average) and rainfall regime (less predictable and reduced
amount) in the target area. Second, phenotyping the populations for
phenology, we observed significantly earlier heading time (up to 10
days) in the 2010 samples. Third, we implemented two genome-scan
methods, one of which specially developed for selfing species, and
detected 31 independent selection footprints. These loci showed
significant enrichment in genes involved in reproductive processes and
bore known heading time QTLs and genes, including OsGI, Hd1 and OsphyB.
This rapid adaptive evolution, originated from subtle changes in the
standing variation in genetic network regulating heading time, did not
translate into predominance of multilocus genotypes, as it is often the
case in selfing plants, and into notable selective sweeps. We argue that
this high adaptive potential results from the multiline genetic
structure of the rice landraces, and the rather large and imbricated
genetic diversity of the rice meta-population at the farm, the village
and the region levels, that hosted the adaptive variants in multiple
genetic backgrounds well before the advent of the environmental
selective pressure. The complex selection footprints observed in this
empirical study calls for further model development on genetic bases of
plant adaptation to environmental changes.
Analysis of temporal and spatial changes of soil erosion under LULCC based on CSLE in the typical watershed on the Loess Plateau
Authors: Zhang Biao , Chen Ziyu , Shi Xuejin , Wu Dr. Shufang , Feng Hao , Gao Xiaodong , Siddique K
Published: July 2022

Extreme meteorological events occur frequently, and changes in the
spatial pattern of land use have greatly affected the soil erosion
process in the hilly and gully region of the Loess Plateau. As a typical
governance watershed in the hilly and gully area of the Loess Plateau,
the Jiuyuangou watershed has experienced significant changes in land use
and land cover (LULCC) in the past ten years due to the conversion of
farmland to forests, economic construction, and abandonment of
cultivated land. However, the evolution process of soil erosion under
LULCC in the watershed is unclear. This study uses satellite images to
extract information on LULCC in the watershed and the Chinese soil loss
equation (CSLE) model to evaluate the temporal and spatial evolution of
soil erosion in the watershed from 2010 to 2020. The main results showed
that: (1) The continuous vegetation restoration project in the watershed
reduced soil erosion from 2010 to 2015; however, the frequency of
extreme rainfall events after 2015 reduced its impact. The annual
average soil erosion modulus decreased from 10.85 t ha
yr in 2010 to 8.03 t ha
yr in 2015, but then
increased to 10.57 t ha yr in
2020; (2) The main LULC type in the Jiuyuangou watershed is grassland,
accounting for 62.23% of the total area of the watershed, followed by
forest land (28.41%), cropland (6.77%), building (2.49%), and water
(0.09%). The multi-year average soil erosion modulus for land use type
is cropland > grassland > building
> forest land; (3) Significant spatial correlations between
soil erosion change and LULCC for common ‘no change’ and common ‘gain’
occurred in the settlements, roads, valleys, and areas near the human
influences with good soil and water conservation, but not other regions
due to the influence of climatic factors (heavy rain events). This study
provides a scientific reference for planning and managing water and soil
conservation and ecological environment construction in the basin.
Effects of straw returning and nitrogen addition on soil quality and physicochemical characteristics of coastal saline soil: A field study of 4 consecutive wheat-maize cycles

Published: July 2022

The effects of different straw returning and nitrogen addition levels on
soil quality are important for proper coastal saline soil remediation.
Two maize/wheat straw returning levels (1.0 × 10 kg
ha (2S) and 5.0 × 10 kg ha
(S)) and three inorganic nitrogen addition levels
(300 kg ha (N2), 150 kg ha (N)
and 75 kg ha (N1/2))—were studied, with 150 kg ha
inorganic nitrogen and without straw addition
treatment as the control (CK), to elucidate the response of soil
physical and chemical properties to the two factors. Dry-sieving
technique was applied to fractionate the soils into silt-plus-clay
particles (< 0.053 mm, CS), microaggregates (0.053–0.25 mm,
MI), small macroaggregates (0.25–2.0 mm, SM), and large macroaggregates
(> 2 mm, LM). After four consecutive wheat-maize cycles,
different straw and N fertilizer treatments obviously decreased the
salinity contents, increased the total nutrient contents, and optimized
the soil structure of the saline soil. The saline soil reclamation
effects showed significant distinctions among the different straw and N
fertilizer treatments. The 2SN2 treatment displayed the greatest effects
in regard to decreasing salinity, increasing the total soil nutrient
contents and optimizing the soil structure, which resulted in the best
remediation effect. Straw returning play a major role in decreasing soil
salinity and enhancing saline soil aggregate formation. N fertilizer
addition supplies rich nutrients for straw decomposition, and promotes
soil microbial growth and reproduction, which brought about C
sequestration in coastal saline soil. During the coastal saline soil
remediation process in the Yellow River Delta, it is suggested to
prioritize straw returning and moderate N fertilizer addition, and live
together with moderate P fertilizer application.
Accuracy of The Single Beat Method for Assessment of Mitral Valve Stenosis Severity in Atrial Fibrillation
Authors: Ardini Tengku , Soesanto Amiliana , Ariani Rina , Rudiktyo Estu , Kuncoro Ario
Published: July 2022

Purpose: In mitral stenosis (MS) patients, determining stenosis
severity in atrial fibrillation (AF) is time-consuming by averaging
measurement by multiple cardiac cycles. Whether a single beat method can
be used to measure the mitral valve area (MVA) and transmitral gradient
for stenosis severity assessment in AF is still uncertain.
Methods: Forty-eight MS patients with AF (mean age 46.8+8.6
years) underwent routine echocardiographic study. The MVA by pressure
half time (PHT) and transmitral mean gradient were measured by four
methods: the standard approach (averaging multiple beats), single short
R-R cycle, single long R-R cycle, and single beat RRp/RRpp = 1. 2D and
3D planimetry MVA were measured at the mitral orifice. Results:
The single beat RRp/RRpp = 1 showed no significant difference in MVA PHT
measurement compared with standard approach (0.8 (0.3 – 2.7 vs 0.9 +
0.3 cm ) cm , P = 0.472),
whereas there was a significant difference in MVA by PHT when short R-R
cycle (1.0 (0.4 – 2.7) cm , P = 0.0001) and
long R-R cycle (0.8 (0.3 – 1.7) cm , P =
0.013) were selected. There was a significant difference in mean MVG
measurement when short R-R cycle (12.1 + 3.9 mmHg, P = 0.001) ,
long R-R cycle (10.1 + 4.0 mmHg, P = 0.007), and single beat
RRp/RRpp = 1 (12.2 + 4.4 mmHg, P = 0.0001) were selected.
Correlation coefficients for MVA PHT calculated by single beat RRp/RRpp
= 1 compared with MVA PHT measured by standard approach are r =
0.87 ( P < 0.001). There is weak correlation in
measurement MVA between PHT single beat RRp/RRpp = 1 and 3D planimetry (
r = 0.316, P = 0.044). Conclusion: In AF, the
single beat method RRp/RRpp = 1 for measurement MVA by PHT in MS has a
high correlation with the current standard approach by averaging
multiple beats. Compared with MVA by 3D planimetry as the reference
measurement of MVA, measurement of MVA by PHT standard approach and
single beat RRp/RRpp = 1 have a weak correlation in AF patients. MVA by
planimetry especially 3D planimetry, is considered as a reference
measurement, but MVA by PHT single beat RRp/RRpp =1 can be an
alternative, especially when MVA by planimetry is not feasible.
Automatic Tracking of Surgical Instruments with A Continuum Laparoscope Using Data-driven Control in Robotic Surgery

Published: July 2022

In existing surgery process, surgeons need to manually adjust the
laparoscopes to provide a better field of view during operation, which
may distract surgeons and slow down the surgery process. This paper
presents a data-driven control method that uses a continuum laparoscope
to adjust the field of view by tracking the surgical instruments. A
Koopman-based system identification method is firstly applied to
linearize the nonlinear system. Shifted Chebyshev polynomials are used
to construct observation functions that transfer low-dimension
observations to high-dimension ones. The Koopman operator is
approximated using a finite-dimensional estimation method. An optimal
controller is further developed according to the trained linear model.
Furthermore, a learning-based pose estimation framework is designed to
detect keypoints on surgical instruments and provide visual feedback for
adjusting the laparoscope. Compared with other detection methods, the
proposed scheme achieves a higher detection precision and provides more
optional keypoints for tracking. Simulation and experiments validate the
feasibility of the proposed control method. Experiment results show that
the proposed method can automatically adjust the field of continuum
laparoscope through tracking surgical instruments in a timely manner and
the number of surgical tools is not limited.
The Mechanics of Diurnal Thermal Stratification in River Pools: Implications for Water Management and Species Conservation

Published: July 2022

We examined conditions that form or prevent thermal stratification in
river pools using field measurements and statistical and
three-dimensional (3D) computational fluid dynamics (CFD) modeling. Our
motivation is to identify variables that control stratification for
exploitation to enhance or prevent thermal gradients as needed to
benefit species in rivers. One study pool (UT) is above water storage
reservoirs and receives natural flows, and the other pool (PT) is
regulated and receives unnaturally high, cold water in summer on the
Trinity River, California. Thermal stratification formed in UT pool in
spring at a critical flow of 1.01 m /s, peaked at 8.1
C in summer, and exhibited diurnal formation and
destruction under sub-critical flows until fall. At PT pool, the 14.2 m
/s baseflow caused mixing that prevented
stratification and formed a spatially homogenous thermal environment.
Statistical modeling indicated the daily range in air and inlet water
temperature at UT pool best correlated with the occurrence and strength
of stratification but were progressively irrelevant as flows increased
above the critical value. The 3D CFD model was verified by predicting
the observed critical flow and dynamics of stratification at UT pool and
isohytes observed at PT pool. The 3D model was then used to explore the
thermal stratification process. Results confirmed low flows are the main
variable for stratification to form, and the daily range in inlet water
temperature drives the strength of the thermal gradient. The model
estimated a critical discharge at PT pool of 2.0 m
/s, twice that for UT pool owing to its 2.6-times
larger area, suggesting critical flows scale with pool size. Results
show that releasing critical and lower flows in summer on regulated
streams may conserve water and provide thermal gradients that benefit
poikilothermic species; alternately, higher than critical flows can
prevent stratification where needed to improve water quality.

Published: July 2022

Classification of natural flow regimes of non-perennial rivers and
streams (NPRS) is an incipient field of research. NPRS represent
approximately 70% of the total Mediterranean rivers and are expected to
increase in the next decades as a result of climate change. Due to the
ecological importance of NPRS and the need to improve national
ecological assessment methods within the scope of the Water Framework
Directive (WFD), this paper aims to classify the hydrological regime of
69 non-regulated streams, testing several hydrological indices related
to the frequency, duration, timing, and rate of change in periods of
flow cessation. Using daily flow records, a total of 315 indices were
calculated and their relationships were examined with Principal
Component Analysis (PCA) for different thresholds used to define
zero-flow condition set at 0, 1, 2, and 5 l/s. Redundancy analysis
identified five indices that better describe the patterns of
hydrological variability in Mediterranean NPRS: number of days per year
without flow, annual percentage of months without flow, mean daily of
annual flows, coefficient of variation of Julian date of the annual
start of zero flow and annual rise rate. Using these indices, a
self-organizing map (SOM) was trained in order to categorize the NPRS
into three groups with similar hydrological features. The results of
this study provide a statistically-based hydrological classification of
NPRS in Mediterranean environments. We expect that this classification
will provide useful insights to water authorities to improve the
assessments of the ecological status in this set of water bodies.

In this study we have designed and fabricated a household solar water desalination unit for the arid regions of rural areas of Sindh like Tharparkar district. Drought conditions, shortage of drinking water and relying on saline water in arid regions of Sindh is a serious problem. In areas under these tracts, it is difficult to obtain drinkable water. This study focuses on the development of a cost effective and affordable desalination unit having simple construction, easy to use, repair, maintain and can be operated by an unskilled man. The solar desalination unit comprises of a solar oven, condenser, and collector pot. In this research various water samples were collected from three arid regions of Tharparkar district i.e., Islamkot, Diplo and Mithi. The performance of solar water desalination unit was assessed by analysing the Total Dissolve Solids (TDS), pH and Electrical Conductivity (EC) of all samples. The sample collected, before treatment had maximum TDS, conductivity, and pH values as 10421 mg/L, 20842 μS/cm and 8 respectively. Those sample after treatment reduced to TDS of 230 mg/L, conductivity of 460 μS/cm and pH of 7.4. This portable solar desalination unit showed remarkable results and found as effective in the removal of TDS from all water samples. The efficiency of unit was calculated as 35.2% with maximum daily output of 5 litres. This unit was constructed at very low cost of PAKPKR 4500/- and its complete rely on solar energy which makes it quite affordable for those which cannot afford expensive treatment techniques. This unit has very minimal maintenance cost and does not require electricity. The values for pH, TDS, and EC achieved from this unit are satisfying the World Health Organization (WHO) guidelines for drinking water quality.

Telecom service providers are on a relentless task of development and upgradation of their networks to support increasing requirements of internet users. FTTX landline connections serves multiple users connected on a single line hence need more robust and high data rate capabilities. In FTTX network, link capacity allocation for a service node to aggregating node requires statistical study of usage patterns of customers of the service areas. Different service areas have different usage patterns hence their statistical distributions are different. In this article we have acquired a yearlong data of peak hour utilizations from customers of the largest FTTX service provider in Pakistan to develop a statistical model. We developed an empirical distribution of peak hours of the customers mapped on day clock. This distribution has been used in Monte Carlo computation to find maximum data rate requirements on aggregation nodes in comparison to subscribed data rates of all users on a service node. Further a forecasting model has been used to predict the growth in subscriber demands in different demographic segments for coming years. A combination of maximum possible data rate requirement at aggregation node and forecasted subscriber data rates led to develop a forecast of data rate requirement for next five years in different demographic segments.

Published: July 2022

The satisfaction of electricity customers and environmental constraints
imposed have made the trend towards renewable energies more essential given
its advantages such as reducing power losses and enhancing voltage profiles.
This study addresses the optimal sizing and setting of Photovoltaic
Distributed Generator (PVDG) connected to Radial Distribution Network (RDN)
using various novel optimization algorithms. These algorithms are
implemented to minimize the Multi-Objective Function (MOF), which devoted to
optimize the Total Active Power Loss (TAPL), the Total Voltage Deviation
(TVD), and the overcurrent protection relays (OCRs)?s Total Operation Time
(TOT). The effectiveness of the proposed algorithms is validated on the test
system standard IEEE 33-bus RDN. In this paper is presented a recent
meta-heuristic optimization algorithm of the Slime Mould Algorithm (SMA),
where the results reveal its effectiveness and robustness among all the
applied optimization algorithms, in identifying the optimal allocation
(locate and size) of the PVDG units into RDN for mitigating the power
losses, enhance the RDN system's voltage profiles and improve the
overcurrent protection system. Accordingly, the SMA approach can be a very
favorable algorithm to cope with the optimal PVDG allocation problem.
