Published: December 2021

Suroboyo Bus merupakan salah satu moda transportasi umum yang disediakan oleh pemerintah Kota Surabaya. Suroboyo Bus memberikan fasilitas penukaran tiket dengan sampah botol plastik yang dibawa oleh penumpang. Botol – botol plastik yang sudah tidak terpakai dapat disimpan dan digunakan sebagai alat tukar pembelian tiket Suroboyo Bus. Selain moda tranportasi umum yang nyaman, untuk menarik animo penumpang diperlukan suatu sistem penukaran tiket yang atraktif dan mudah digunakan. Untuk itu penelitian ini berfokus pada pengembangan sistem penukaran tiket Suroboyo Bus melalui digitalisasi penukaran tiket. Tanpa merubah esensi dari kehadiran Suroboyo Bus itu sendiri, proses penukaran sampah menjadi tiket dapat dilakukan dengan aturan penukaran yang sudah ada. Jika penukaran sampah botol plastik biasanya dilakukan di Halte Bungurasih, Halte Rajawali, dan di dalam Suroboyo Bus, penelitian kali ini membuat sebuah prototype sistem penukaran tiket menggunakan layanan operator pada halte yang ditentukan. Operator bertugas untuk mengkonversi jumlah sampah yang ditukar dengan sejumlah tiket melalui web. Web terhubung dengan database server sehingga jumlah tiket yang diperoleh dapat ditampilkan pada aplikasi android milik penumpang. Tiket elektronik yang terdapat pada aplikasi android dapat digunakan untuk naik Suroboyo Bus ketika penumpang telah melakukan scan kode QR yang terdapat pada Suroboyo Bus. Kode QR digunakan sebagai alat validasi tiket. Dengan kemudahan akses dan cara kerja yang sederhana diharapkan semakin banyak warga yang menggunakan Suroboyo Bus sebagai alat transportasi penunjang mobilitas sehingga  dapat memberikan dampak yang signifikan terhadap kemacetan.

Authors: Thenata Angelina Pramana
Published: December 2021

Era sekarang jumlah berita dari berbagai media sosial yang tersebar dalam waktu singkat dan kebutuhan masyarakat untuk mengkonsumsi berita dalam berbagai referensi dapat mempengaruhi kehidupan masyarakat. Hal ini menyebabkan data yang tersebar dapat dikumpulkan dan dimanfaatkan oleh pemerintah, pengusaha, analisis, ataupun peneliti untuk mengidentifikasi tren, mengembangkan bisnis, memprediksi perilaku pelanggan dan lain sebagainya. Pengumpulan data berita dari media sosial tersebut dapat menggunakan text mining yang melibatkan algoritma yakni Naive Bayes, K-NN, dan SVM. Namun, penggunaan algoritma pada studi kasus yang tidak sesuai dapat memberikan hasil yang tidak optimal. Oleh karena itu, penelitian ini akan menganalisis algoritma text mining yang diimplementasikan pada media sosial berbahasa Indonesia dengan memakai metode systematic literature review. Metode ini dimulai dengan melakukan tahap planning yang menetapkan pertanyaan penelitian, kata pencarian, sumber literatur digital, dan standard literatur. Dilanjutkan dengan tahap conducting yang memilih dan mencocokan standard literatur, serta ekstraksi data. Kemudian tahap reporting yang melakukan analisis hasil ekstraksi data sehingga bisa menemumkan informasi dan pengetahuan. Tolak ukur yang menjadi acuan untuk perbandingan yakni pengujian confusion matrix berupa accuracy, precision, dan recall. Adapun hasil dari penelitian ini ditemukan algoritma Naive Bayes memberikan hasil yang stabil tapi kurang optimal jika diterapkan pada studi kasus media sosial berbahasa Indonesia. Sedangkan algortima K-NN dan SVM ditemukan memberikan hasil yang optimal jika diterapkan pada studi kasus media sosial berbahasa Indonesia yang dibuktikan dengan accuracy (50%-98.13%), precision (58.22%-98.48%), dan recall (21.05%-98%).

Moving Mountains: Reshaping the Activity Volcano of Electrocatalysis with Fluxional Subnano Clusters
Authors: Zhang Zisheng , Zandkarimi Borna , Munarriz Julen , Dickerson Claire , Alexandrova Anastassia N.
Published: December 2021

The activity volcano derived from Sabatier analysis provides intuitive guide for catalyst design, but it also imposes fundamental limitations on the maximal activity and the pool of high-performance elements. Here we show that the activity volcano for oxygen reduction reaction (ORR) can be shifted and reshaped in the subnano regime. The fluxional behavior of subnano clusters, in both isolated and graphite-supported forms, not only breaks the linear scaling relationships but also causes an overall strengthening in adsorbate binding. The metals with optimal adsorbate binding in the bulk form (Pt/Pd) thus suffer over-binding issues, while the metals that under-bind in the bulk form (Ag/Au) gain optimal reaction energetics. In addition, the potential-dependence of isomer energies differ, causing non-linear reaction free energy-potential relations and enabling population-tuning of specific isomers, thereby surpassing the apex of the activity volcano. The shift of the volcano that puts under-binding elements closer to the top is likely general in fluxional cluster catalysis, and can be used for cluster catalyst design.

Published: December 2021

We report a facile method of synthesizing grain-boundary(GB)-rich platinum nanoparticle assembly. GBs are formed between platinum nanoparticles during their random collision and attachment in solution driven by water electrolysis. The GB-rich nanoparticle assembly exhibits ~400-fold higher catalytic hydrogen oxidation rate than platinum nanoparticles before assembly, enabling catalytic hydrogen sensing at room temperature without external heating. Our sensor also demonstrates fast response/recovery (~7 s at >1% H2), nearly no signal variation during a 280-hour-long stability test, and high selectivity toward hydrogen over 36 interference gases. Furthermore, this sensor can be easily fabricated from commercial thermometers at a low cost (< $5 per unit). Theoretical calculation results reveal that the high performance of GB-rich platinum nanoparticle assembly arises from tensile strain at the GBs.
Determinantes sociales de la salud mental: políticas públicas desde el modelo biopsicosocial en países latinoamericanos
Authors: Leiva- Peña Varinia , Rubí-González Patricia , Vicente-Parada Benjamin
Published: December 2021

En este artículo se expone la evidencia sobre la implementación de políticas públicas en salud mental, con el objetivo de describir los avances y los desafíos para poner en marcha el modelo biopsicosocial y comunitario principalmente en Latinoamérica. Se realizó una revisión teórica de artículos indexados en Web Of Science, Scopus, PubMed y SciELO. Se incorporaron informes y programas gubernamentales. Los determinantes sociales impactan a la salud mental, la pobreza aumenta significativamente el riesgo de desarrollar una psicopatología. Por ello, la Organización Mundial de la Salud insiste en la necesidad de adoptar un paradigma biopsicosocial para enfrentar los desafíos de salud mental. Alrededor de un tercio de los países, todavía no cuenta con una política nacional de salud mental y existen grandes disparidades de financiamiento y cobertura para la población entre países de ingresos altos y bajos. Particularmente de Latinoamérica, los resultados ilustran un avance en países de ingresos medios y bajos, en elaborar programas de salud mental desde un enfoque comunitario y biopsicosocial. Sin embargo, presentan desafíos en su operacionalización, financiamiento y adaptación a sus realidades socioculturales. La evidencia indica que para avanzar desde un paradigma biomédico hacia uno que incorpore los determinantes sociales de la salud, no se deberían mantener idénticas estrategias en comunidades distintas, puesto que las necesidades de países de ingresos bajos y medios difieren a las de países de ingresos altos. Por ello, resulta fundamental aumentar la investigación local para generar evidencia que refleje las necesidades nacionales en materia de políticas públicas en salud mental.
Evaluating mitigation translocations for better biodiversity outcomes
Authors:   , Dean Sydney
Published: December 2021

The expansion of urban areas and associated loss of natural areas due to development are greatly contributing to global biodiversity loss. Furthermore, development produces direct harm to wildlife and their habitat. In New Zealand, lizards and their habitat are legally protected and damage due to development of a natural area must be avoided or mitigated whenever possible. Mitigation translocations, the intentional relocation of individuals from the site to be developed to a receptor site, have become commonly used to meet legal obligations; however, mitigation translocations do not guarantee survival of individuals or population success at the receptor site. I aimed to evaluate the success of a mitigation translocation case study, proactively plan receptor sites for a mitigation translocation, and develop a framework for selecting and preparing receptor sites to provide better mitigation translocation outcomes, particularly for herpetofauna. I evaluated the short-term success of a mitigation translocation case study using results from post-release monitoring at receptor sites. This is one of the first studies to provide multiple post-release monitoring sessions and detail recapture rates and body condition changes of lizards at receptor sites with and without resident populations following mitigation translocation. I expanded upon commonly used receptor site selection criteria and translocation data management systems by proactively studying and preparing receptor sites in regional parks, including conducting pilot surveys to evaluate resident populations. Recapture rates were similar between receptor sites (9% and 11.8%) and the limited number of recaptured individuals showed an increase in body condition from the time of salvage to intervals of one- and two-years post-release. Presence of residents was not found to have an effect on recapture rates or body condition changes. Implementation of enhanced site selection criteria resulted in approval of six sites within three protected areas for future mitigation translocations. These sites had low numbers of resident lizards present, if at all. A geodatabase was developed to store results from receptor site evaluations before and after translocation. Together, the improved criteria and geodatabase fit into a framework for selecting and preparing receptor sites to improve outcomes of mitigation translocations of herpetofauna. The framework produced has potential to be used at a national level, in collaboration with ecologists, iwi, and community groups, and for a variety of species. Mitigation translocations should be re-evaluated as the go-to method to mitigate damage to lizards due to development; however, if they must continue, it is essential that best practices are used, and results are published so that outcomes can improve for biodiversity.
Determination of the optimum ball radius for researching materials using ball indenting
Authors: Avtonomov N. N. , Tololo A. V.
Published: December 2021

The article discusses the study of the effect of a change in the radius of the ball in the injecting of the sample on the curve in the coordinates «load – indentation depth», the deviation of the indentation depth during elastoplastic indentation from the indentation depth with the elastic indentation and the amount of the axial deformation of the ball. The study was conducted using the Ansys Mechanical APDL program implementing the fenite element method. In the process of the study, it was found that with a change in the radius of the ball, there is no obvious change in the behavior of the sample material, and the deviation of the indentation depth during the elastoplastic indulgence from the indentation depth during the elastic indentation is not dependent on the size of the ball radius. There was also an effect of changing the radius of the ball on the size of the axial deformation of the ball and proposed a formula for determining the size of the axial deformation of the ball for the ball of any diameter, which will determine the actual depth of the ball into the ball when using the balls of different radius.
Wave theory of the laminated plates with approximate consideration of the transverse shear
Authors: Sibiryakov A. V.
Published: December 2021

Composite materials are widely used in the production of aircraft for various purposes. Having several unique properties, composites, due to their heterogeneous structure, are poorly resistant to shock loads. Impulse action spreads inside the material in the form of stress waves, which are reflected on internal inhomogeneities, can overlap, and create very significant bursts of stress. This often leads to the well-known types of failure – spalling and delamination. Practice shows that these fractures occur almost immediately after the loading impulse. To verify the spalling strength, it is necessary to consider the initial unsteady phase of the response to the external impulse. There are sufficiently reliable theories to verify this strength; usually, they do not take transverse shear into account, otherwise the solution becomes unnecessarily cumbersome and poorly observable. Nevertheless, attempts are often made to refine the calculations by approximate consideration of transverse shear. This article presents the wave theory of laminated plates with approximate consideration of transverse shear. The possibility of specifying the calculation of impulse-loaded plates is considered. The inconsistency of the resulting model is proved.

Nature connection through film
Authors: Breden Andreas
Published: December 2021

These notes accompany two films that I have made. They are an attempt to punctuate why my connection to nature is so important to me and try to find a way to share this. I write attempt because I believe that we as human beings are ever-evolving, ever-revealing and ever-growing, and so is our relationship and connection to nature. It’s not a circular movement, but more like a spiraling one which adds one more dimension. We come back to places that are familiar but slightly different.

Deep Dive Into The Mesozoic Play Potential Beneath The Batui Thrust: A Case Study in The Offshore Matindok, The Eastern Arm of Sulawesi
Authors: Bahesti F.
Published: December 2021

This article summarized the exploration ideas and methods for a closer look at the Mesozoic hydrocarbon potential in the Banggai Basin, offshore Matindok, Eastern Arm of Sulawesi. The area is one of the Pertamina EP’s working area which located in the frontier basin that has an acreage exceeding 10,000 sqkm. A major portion of the Mesozoic play in the basin is still under explored, whilst/whereas the existence of an active Cenozoic petroleum system in the offshore Matindok has been confirmed by Tiaka Producing Field. The main challenge in exploring the Mesozoic section in the Matindok Block is imaging it below the ophiolite complex / ultra-mafic layer of the Batui thrust, as well as the thick Neogene carbonate. These barriers inhibit the penetration of seismic energy that resulted in low-quality seismic data beneath the thrust. In order to generate its play concept, massive exploration efforts have been conducted in the Matindok Block since 2017. It consists of onshore geological fieldwork, high-resolution satellite data processing, and the new acquisition of shallow-marine transition 2D seismic data. Potential mature source rocks of the Triassic Tokala marine shale was found in the outcrops nearby the Batui thrust. In the seismic interpretation, the equivalent Jurassic to Cretaceous outcrops that dominated by the fluvio-deltaic sandstones, have been interpreted as pinched-out features along the margin of half graben structures. This area was compressed during the Late Miocene to Plio-Pleistocene shortening events, and intensively imbricated the Cenozoic to present-day sediments on the Batui thrust, but put the Paleozoic - Mesozoic half-grabens beneath the Batui thrust decollement. Finally, the finding of this study is able to demonstrate the petroleum-system risks assessment of the Mesozoic hydrocarbon potential.
Mature field Development to Periphery Area: Tambora West Flank development
Authors: Priastomo Y. S
Published: December 2021

Tambora gas field, discovered in 1974 is located in a swamp area at the apex of Mahakam Delta, and it is adjacent to Nilam field, which is operated by another operator. Geologically, the Tambora and Nilam Fields have the same anticline structure that originates from the sediment provenance west of Kalimantan as reflected in present day Mahakam Delta. Therefore, this study aims to analyze the challenges to unlock the potential of the west flank area of Tambora Fields. The geological synthesis of both Tambora and Nilam fields shows similar net sand and pay distribution in lateral and vertical proportions. Most developments in the Tambora Anticline area are in the crest and the distances between wells are ~100-200m. Challenges to unlock potential in flank areas are derived from the limitation of wells and seismic data. Based on data and knowledge of the flank areas in both fields, the west flank has better productivity compared to the east. Therefore, geological synthesis is conducted in the west flank area to define hydrocarbon and reservoir properties. Furthermore, channel models were made from 2D seismic scouring, controlled by the continuation of well log channel facies in the anticline crest area. Based on the preliminary approach, 3 wells were proposed to unlock west flank Tambora potential and were integrated into the plan of development. Primarily, dynamic uncertainty affects the potential of the west flank since production in the anticline crest area is enormous, and the uncertainty was analyzed by drilling one recent well. The result shows that hydrocarbon in the flank is not fully connected with the anticline crest area and has proven the sidebar heterogeneity concept. These gave more confidence to seek further positive results and develop west flank Tambora to sustain Mahakam production in the future.
Characterizing the Seismic Response of Naturally Fractured Basement Reservoir in Sumatra Area: Towards an Efficient Seismic Exploration Strategy
Authors: Wardaya P. D.
Published: December 2021

Although only contributes few to the total oil and gas production, fractured basement reservoir is one of the important unconventional reservoirs in Indonesia. It was estimated that the gas reserve in basement in South Sumatra is about 6 TCF (trillion cubic feet). Most of the existing geophysical methods is not intended to explore events within the basement. In fact, majority of basement reservoir discovery was coincident. Despite its significant contribution to Indonesia’s gas production, the exploration success story in the fractured basement play is still poorly documented. The challenges and difficulties in their characterization are higher than the conventional reservoir. This study presents an integrated geological and geophysical approach to improve the outcome of seismic imaging of the fractured basement reservoir. A comprehensive geological study and geophysical modelling were conducted to provide an efficient strategy for designing an optimum seismic survey in imaging the fractures within the basement. Both surface and subsurface data were thoroughly analyzed to yield a reliable representation of the subsurface fracture model at basement level. Outcrop sample analysis combined with aerial remote sensing analysis were performed as input to digital outcrop modelling. The modelling was intended to provide information about fracture orientation, length, and density. This will provide a fracture property in the surface which is related to the fracture properties in subsurface. The resulting fracture properties was then used as an input to evaluate the seismic wave response during its propagation in the reservoir. Seismic modelling has been done using a 2D finite-difference full wavefield approach in a Graphics Processing Unit (GPU) accelerated computing system. We observe how fracture properties affect the propagating seismic wavefield. Wave scattering is observed more prominently around the fracture tip when the fracture plane is orthogonal to wavefield direction.
Mid-crustal detachment beneath southern Timor-Leste: seismic evidence for Australian basement in the Timor collision complex (and implications for prospectivity)
Authors: Charlton T. R.
Published: December 2021

Seismic data originally acquired over SW Timor-Leste in 1994 shows two consistent seismic reflectors mappable across the study area. The shallower ‘red’ reflector (0.4-1s twt) deepens southward, although with a block-faulted morphology. The normal faults cutting the red marker tend to merge downward into the deeper ‘blue’ marker horizon (0.5-2.8s twt), which also deepens southward. Drilling intersections in the Matai petroleum exploration wells demonstrate that the red marker horizon corresponds to the top of metamorphic basement (Lolotoi Complex), while the blue marker horizon has the geometry of a mid-crustal extensional detachment. We see no indications for thrusting on the seismic sections below the red marker horizon, consistent with studies of the Lolotoi Complex at outcrop. However, surficial geology over much of the seismic survey area comprises a thin-skinned fold and thrust belt, established in 8 wells to overlie the Lolotoi Complex. We interpret the fold and thrust belt as the primary expression of Neogene arc-continent collisional orogeny, while the Lolotoi Complex represents Australian continental basement underthrust beneath the collision complex. In the seismic data the basal décollement to the thrust belt dips southward beneath the synorogenic Suai Basin on the south coast of Timor, and presumably continues southward beneath the offshore fold and thrust belt, linking into the northward-dipping décollement that emerges at the Timor Trough deformation front. The same seismic dataset has been interpreted by Bucknill et al. (2019) in terms of emplacement of an Asian allochthon on top of an imbricated Australian passive margin succession. These authors further interpreted a subthrust anticlinal exploration prospect beneath the allochthon, which Timor Resources plan to drill in 2021. This well (Lafaek) will have enormous significance not only commercially, but potentially also in resolving the long-standing allochthon controversy in Timor: i.e., does the Lolotoi Complex represent ‘Australian’ or ‘Asian’ basement?

Published: December 2021

One of the alternatives to reduce waste in Indonesia is the establishment of a Waste Bank. The role of waste bank actors is not the same as collectors or scavengers, they are expected to have entrepreneurial and personal characteristics. The purpose of this study is to analyze the forming factors of entrepreneurial activity in waste banks that contribute to the growth of a sustainable waste processing business. This research was conducted in Sawangan Depok. The first research stage collected primary data using a questionnaire on 111 active waste bank actors using the purposive sampling technique, then analyzed the data using Structural Equation Modeling (SEM). The results showed that the goodness fit criteria were met and the measurement variables in the model had good reliability (CR≥0,70, VE≥0,50). The entrepreneurial activities of waste bank actors are most influenced by entrepreneurial characteristics (γ = 0,70) and resources (γ = 0,63). The entrepreneurial characteristics of the waste bank actors are well shaped by motivation (λ = 0,40), risk (λ = 0,49), and innovation (λ = 1,00). The implication is that to grow a sustainable waste bank requires an innovative character for the waste bank actors.

A elaboração do questionário caracteriza-se pelo delineamento qualitativo-exploratório, por conseguinte a elaboração e encaminhamento da entrevista foram realizados com uso do Google Forms e os dados da pesquisa foram obtidos remotamente. Os resultados evidenciam a sobrecarga emocional e dificuldade em acompanhar/conciliar deveres acadêmicos e vida pessoal durante a quarentena, outro fator é a insegurança e as incertezas diante de uma nova realidade na qual tudo é realizado remotamente em razão da pandemia. Ao analisar os resultados, conclui-se que o acesso à internet tem dois eixos, o primeiro eixo pode facilitar a comunicação e acessibilidade, contudo o segundo eixo pode dificultar o ensino, caso o aluno não tenha os recursos necessários ou acesso à internet de qualidade para acompanhar o ensino remoto. Constatou-se que o ensino remoto pode vir a causar um impacto psicológico negativo causado pela ausência de contato humano no cotidiano, considerando que as relações sociais e convívio podem influenciar, ou até mesmo amparar os indivíduos em momentos de uma crise de saúde mundial.
Os cristãos frente ao desafio da diversidade religiosa
Authors: Carrara Paulo Sérgio
Published: December 2021

A globalização aproximou as religiões, gerando a necessidade do diálogo inter-religioso como dispositivo para a paz e a fraternidade mundiais. O Vaticano II abordou o tema da diversidade religiosa alargando o conceito de salvação cristã e reconhecendo as religiões como legítimos caminhos históricos para a salvação. O pluralismo religioso atual acentua a necessidade do diálogo e da coloração mútua entre as tradições religiosas. O presente artigo sintetiza o ensinamento do Vaticano II e do magistério posterior. Apresenta as razões teológicas para o diálogo inter-religioso a partir da contribuição de dois renomados teólogos atuais, Andrés Torres Queiruga e Luis Francisco Ladaria. Reforça aspectos do magistério do Papa Francisco sobre a importância do diálogo e da colaboração entre as religiões em vista da urgência da paz mundial. O artigo busca, ainda, oferecer aos cristãos fundamentos teológicos basilares que os ajudem a promover o diálogo, evitando a intolerância e o fundamentalismo.

Yersiniosis is a zoonotic disease which infects many animal species. A preliminary study was done to detect the incidence of Yersinia enterocolitica in sheep. One thousand and two hundred fecal samples were collected randomly from sheep in four governorates in the southern region of Iraq: Thi-Qar, Al-Muthana, Messan and Basrah, in the period from July 2016 to June-2017. Enrichment Yersinia broth at 4°C for 48 hours was used for isolation of Yersinia enterocolitica. Selective Cefsulodin Irgasan Novobiocin and non selective media were used for bacterial culture. The identification of Yersinia enterocolitica was based on colony morphology and biochemical characters, API 20E and VITEK2 compact systems were used for the same purpose also. Data were analyzed by using SAS, Version 9-1. Chi- square test was used for comparison. The total isolation rate of Y. enterocolitica was 5.16% (62). High and low rates of isolation were recorded in Al-Muthana (6. 01%) and Basrah (3.86%). Similarly a significant high isolation rate was recorded in diarrheic sheep (17.4%), moreover the infection rate increased significantly (9.5%) in the young sheep (1day to 6 month's age). Furthermore, the recovery rate of Y. enterocolitica  increased significantly during the cold months (12%) as compared with temperate and hot months (spring and summer), at the same instance, non significant variation among sex difference was detected. Fever, diarrhea and mild to moderate degree of dehydration were the most common clinical manifestations observed on the infected animals. Conclusively sheep were considered a source of infection to other species including human being, and the spread of microorganism increased markedly in the cold and wet environment.

One hundred and fifty stool sampling were collected from clinical sources responsible of causing diarrhea in adults as well as children. The identification of Aeromonas hydrophila isolates depended on common methods of identification dependent on biochemical characteristics and culture, then vitek2 compact system was used. Eight Aeromonas hydrophila isolates were gained and revealed various productivity of metalloprotease; the isolate number 8 was the maximum effective in metalloprotease production. The eight isolates were examined with Polymerase Chain Reaction to prove enzyme gene presence, the results revealed that all isolates were positive for ahMP genes; metalloprotease was completely purified via a number of steps, which included ammonium sulphate precipitation, dialysis, ion exchange and gel chromatography. Cytotoxicity effect of metalloprotease studies on cancer and normal cell lines, The results showed the purified metalloprotease as effective cytotoxic effect on liver hepatocellular cancer cells (HepG2) compared with no effect on normal liver cell line (WRL-68) indicating less cytotoxic effect.

Velogenic Newcastle Disease Virus was isolated from broiler chickens in Northern Iraq. An inactivated vaccine was manufactured locally using as seed virus ELD50/ml109 and then compared with commercial inactivated vaccine in an experimental study which included 120 broiler chicks divided into three groups (G1 unvaccinated control, G2 for commercial vaccine and G3 for local vaccine). The chicks were injected subcutaneously at 3 days old followed by booster Lasota live vaccine eye drop. Indirect ELISA technique was used to estimate the antibody titer from the collected sera of chicks at age 7, 17 and 27 days (pre-challenge) and challenged at 31 days old with the same virus. The results indicated that there were significant differences (P<0.05) between vaccinated group G2 and G3 at 27th day old and showed a high antibody level with high protection percentage compared with the control. G1 which shown no survival, 100% mortality and severe histopathological lesions, while in G2 and G3 was 43% and 87% respectively. Post-challenge antibody titers of survival chicks showed in G3 significantly over the G2 with less severe histopathological lesions. This study concluded that vaccine failure could occur due to factors of the immune status of the host, improper storage of vaccine, improper vaccination and variant pathogenic virus strain. More epidemiological surveillances are required to decide the actual impact of the disease in poultry farms and   matching the vaccines.

Authors: Khalaf Ahmed Saadi , Aldoori Atheer
Published: December 2021

A total of 50 fecal samples were collected from buffalo calves ages between 3 days to 4 months, in middle area of Iraq (Baghdad, Salahaldden, Babylon, Diyala, and Wasit) between July 2016 to June 2017. All samples were examined by Immuno-chromatographic rapid tests for detection of buffalo rotavirus, twenty samples were positive. Enzyme-Linked Immunosorbent Assay. test was also used and  revealed only 8  positive samples, the later samples   were used for viral isolation on  fetal bovine kidney cell culture for detection the cytopathogenic  effects of the virus. The cytopathogenic effects of virus were induced rounded cells and gaps; as a result of rupture of these infected cells by rotavirus. Moreover Enzyme-Linked Immunosorbent Assay  test used again for detection of rotavirus cytopathogenic effect in fetal bovine kidney cell culture for more confirmation. The TCID 50 was estimated for rotavirus on fetal bovine kidney cells 104.5 virus/0.05 ml

Due to the visibility of soot in the environment of the Niger Delta especially Rivers State that has led to the increase of  espiratory Tract Infections (RTIs) in the region, this study was undertaken to determine the relationship between Particulate Matter (PM2.5) concentration and the incident of Respiratory Tract Infections (RTIs) in selected urban centres of the Niger Delta. Data on RTIs were collected from the Hospital Management Boards of the Ministries of Health of Rivers, Bayelsa and Delta States and the data for PM2.5 were remotely sensed from 2016 to 2019, and subsequently analyzed with ANOVA and Spearman’s rank correlation statistics. The findings of this study revealed that there was significant variation in the occurrence of PM2.5 across the selected urban centres in the Niger Delta Region. The PM2.5 for the reviewed years was far above the World Health Organization (WHO) annual permissible limit of 10 µg/m3 thereby exacerbating Respiratory Tract Infections (RTIs).The epidemiology of the RTIs showed that there are basically four (4) prominent RTI diseases: Asthma, Tuberculosis, Pneumonia and Chronic Obstructive Pulmonary Disease (COPD). The result of this study showed that the concentration of PM2.5 varies in all the selected cities, and the mean monthly variation (2016-2019) showed that Port Harcourt had 47.27 µg/m3 for January while Yenagoa and Asaba had 46 µg/m3 and 47.51 µg/m3 respectively for January; while the lowest mean value in the cities were seen within the month of September and October, which also had a strong seasonal influence on the concentration of PM2.5. The concentration of PM2.5 and the numbers of RTIs also gradually increases in the study areas from 2016 to 2019. The study recommends that the necessary regulatory bodies should closely monitor the activities of the companies likely to cause such pollution; guild them through their operations and give prompt sanctions and heavy fines to defaulters of the accepted standards.
Ekohyvinvointivaltion katveessa

Inkontinenssi, eli virtsan- tai ulosteenkarkailu, on yleinen vaiva. Kehon vuodoista ja vuotojen hallitsemiseen käytettävistä vaipoista, eli inkontinenssisuojista, kuitenkin vaietaan. Jätteiden tavoin ne ovat hyvinvointivaltiossa hyvinvoinnin katveessa. Erilaiset yhteiskunnan rakenteet ja käyttäytymisen normistot sulkevat vaipat hallinnollisen kielen ulkopuolelle ja tekevät niistä näkymätöntä ja jotain, minkä ei kuuluisi häiritä. Vaippajäte on siis kaksinkertaisesti katveessa, vaikka toisaalta läsnä kaikkialla. Tällaiset hyvinvoinnin vaietuimmat nurkat tulisi ottaa tarkasteluun visioitaessa ekohyvinvointivaltiota, jossa ekologisesti kestävä, hyvä elämä on voitava taata kaikenlaisille kehoille, myös pidätyskyvyttömille. Analysoimme suomalaista vaippataloutta kartoittavia havainto- ja haastatteluaineistoja yhdistäen monipaikkaisen etnografian menetelmiä feministiseen tieteenteknologiaan ja derridalaiseen dekonstruktion tutkimusperinteeseen. Piirrämme artikkelissamme ekohyvinvointivaltion suuntaviivoja inkontinenssin ja vaippatalouden näkökulmasta. Väitämme, että ekohyvinvointivaltion on oltava vuotaville kehoille suunniteltu hyvinvointivaltio: kyse on esimerkiksi hoitoketjuista, ennaltaehkäisystä ja kuntoutuksesta, julkisen tilan ja hoivarakentamisen suunnittelusta sekä terveysturvallisesta sanitaatiosta, jota viemäröinti ei yksin ratkaise.
