IPHAS J025827.88+635234.9 and IPHAS J051814.33+294113.0: Two probable eclipsing intermediate polars
Authors: Joshi Arti , Pandey Jeewan Chandra
Published: January 2022

We present photometry in the R-band and linear polarimetry of two cataclysmic variables, namely IPHAS J025827.88 + 635234.9 and IPHAS J051814.33 + 294113.0. The data were obtained from 1-m class tele-scopes of the Aryabhatta Research Institute of Observational Sciences (ARIES; Nainital, India). In addition to the deep eclipse, strong short-period oscillations are also found. We derived a pulse period of (1203 ± 25) s for IPHAS J025827.88 + 635234.9 and (3277 ± 81) s for IPHAS J051814.33 + 294113.0. The presence of both orbital and spin modulations in these systems indicate that they belong to a class of intermediate polars. The full width at half depth of the eclipse is also found to be variable from epoch to epoch for IPHAS J025827.88 + 635234.9. The presence of a variable linear polarization of high value in these two sources indicates that these systems possess a strong magnetic field.
X-ray observations of the colliding wind binary WR 25
Authors: Arora Bharti , Pandey Jeewan Chandra
Published: January 2022

Using the archival data obtained from Chandra and Suzaku spanning over '8 years, we present an analysis of a WN6h+O4f Wolf-Rayet binary, WR 25. The X-ray light curves folded over a period of '208 d in the 0.3 - 10.0 keV energy band showed phase-locked variability where the count rates were found to be maximum near the periastron passage. The X-ray spectra of WR 25 were well explained by a two-temperature plasma model with temperatures of 0.64 ± 0.01 and 2.96 ± 0.05 keV and are consistent with previous results. The orbital phase dependent local hydrogen column density was found to be maximum just after the periastron passage, when the WN type star is in front of the O star. The hard (2.0 - 10.0 keV) X-ray luminosity was linearly dependent on the inverse of binary separation which confirms that WR 25 is a colliding wind binary.

Published: January 2022

We present the results of an analysis of photometric time-series observations for NGC 2126 acquired at the Thai National Observatory (TNO) in Thailand and the Mount Lemmon Optical Astronomy Observatory (LOAO) in USA during the years 2004, 2013 and 2015. The main purpose is to search for new variable stars and to study the light curves of binary systems as well as the oscillation spectra of pulsating stars. NGC 2126 is an intermediate-age open cluster which has a population of stars inside the  Scuti instability strip. Several variable stars are reported including three eclipsing binary stars, one of which is an eclipsing binary star with a pulsating component (V551 Aur). The Wilson-Devinney technique was used to analyze its light curves and to determine a new set of the system’s parameters. A frequency analysis of the eclipse-subtracted light curve was also performed. Eclipsing binaries which are members of open clusters are capable of delivering strong constraints on the cluster’s properties which are in turn useful for a pulsational analysis of their pulsating components. Therefore, high-resolution, high-quality spectra will be needed to derive accurate component radial velocities of the faint eclipsing binaries which are located in the field of NGC 2126. The new Devasthal Optical Telescope, suitably equipped, could in principle do this.

Published: January 2022

We have made UBV I CCD observations for the open clusters Teutsch 1, Riddle 4 and Czernik 6 using 1.04-m Sampurnanand telescope located at the ARIES observatory (Manora peak, Nainital, India). We have used 2MASS JHKS data for the clusters Teutsch 126, Teutsch 54 and Czernik 3. For the estimation of fundamental parameters, we have plotted radial density profiles, colour-magnitude and colour-colour diagrams. Using these inputs, we have studied the structure of Milky Way Galaxy in the second Galactic quadrant. We have considered the open clusters that are younger than 1 Gyrs and lay in the longitude range from 90 to 180 deg. Our study shows that up to 3.5 Kpc, the Galactic disc bends towards the southern hemisphere while after 3.5 Kpc it bends towards the northern hemisphere. The distribution of reddening with longitude and age shows a decreasing trend with the longitude and age of the clusters. Our study also indicates that younger clusters have more reddening than older ones.
Gravitational Lensing and Microlensing in Clusters: Clusters as Dark Matter Telescopes
Authors: Safonova Margarita
Published: January 2022

Gravitational lensing is brightening of background objects due to deflection of light by foreground sources. Rich clusters of galaxies are very effective lenses because they are centrally concentrated. Such natural Gravitational Telescopes provide us with strongly magnified galaxies at high redshifts otherwise too faint to be detected or analyzed. With a lensing boost, we can study galaxies shining at the end of the “Dark Ages”. We propose to exploit the opportunity provided by the large field of view and depth, to search for sources magnified by foreground clusters in the vicinity of the cluster critical curves, where enhancements can be of several tens in brightness. Another aspect is microlensing (ML), where we would like to continue our survey of a number of Galactic globular clusters over time-scales of weeks to years to search for ML events from planets to hypothesized central intermediate-mass black holes (IMBH).
Temporal variations on chlorophyll concentration in Riñihue lake (39° S, Patagonia, Chile) and its relation with satellite Landsat ETM+ spectral data.
Authors: De los Rios Patricio , Acevedo Patricio , Castro Manuel
Published: January 2022

The Chilean north Patagonian lakes formerly called “Araucanian lakes” (38oS-41° S), were described originally as oligotrophic, nevertheless since 1978, a transition from oligotrophy to mesotrophy has been reported in some bays due to human intervention, such as towns and industrial activities. The aim of the present study was to analyze the temporal variations between five years in a north Patagonian lake comparing chlorophyll concentration with spectral properties based on LANDSAT ETM+ sensor. The results revealed significant direct correlation between chlorophyll concentrations with B2, B3. B4, B5 and B7 reflection bands. The multiple regression analysis revealed a direct association between chlorophyll concentrations with B4, and inverse with B5.  The obtained results agree with observations for other Chilean north Patagonian lakes about chlorophyll increase in determined bays with human intervention, and the use of remote sensing techniques would be an optimal tool for study changes.

Les moustiques ont un rôle épidémiologique en tant que vecteur de plusieurs agents pathogènes capables d’affecter l’homme. L’inventaire des Culicidés durant la période de janvier à mai 2017 nous a permis de connaître leurs répartitions spatio-temporelles dans plusieurs stations de la région de Bousaâda (M’Sila).  Les échantillonnages larvaires de moustiques ont été effectuées par d’une louche, dans les milieux urbain et rurale dans quatre localités situées dans différentes altitudes. Les résultats d’identification montrent l’existence de 11 espèces dans la région étudiée (Culiseta longiareolata, Culiseta subochrea, Culex pipiens, Culex deserticola, Culex theileri, Culex laticinctus, Culex brumpti, Culex perexiguus, Anopheles cinereus, Anopheles multicolor, Uranotaeniaunguiculata). Cet inventaire est complété par une analyse physico-chimique de l’eau pour étudier la corrélation entre la densité larvaire des moustiques et la qualité de gîte.
Light Curve Parameters of Cepheid and RR Lyrae Variables at Multiple Wavelengths − Models vs. Observations
Authors: Singh Harinder Pal , Das Susmita , Bhardwaj Anupam , Kanbur Shashi , Marconi Marcella
Published: January 2022

We present results from a comparative study of light curves of Cepheid and RR Lyrae stars in the Galaxy and the Magellanic Clouds with their theoretical models generated from the stellar pulsation codes. Fourier decomposition method is used to analyse the theoretical and the observed light curves at multiple wavelengths. In case of RR Lyrae stars, the amplitude and Fourier parameters from the models are consistent with observations in most period bins except for low metal-abundances (Z < 0.004). In case of Cepheid variables, we observe a greater offset between models and observations for both the amplitude and Fourier parameters. The theoretical amplitude parameters are typically larger than those from observations, except close to the period of 10 days. We find that these discrepancies between models and observations can be reduced if a higher convective efficiency is adopted in the pulsation codes. Our results suggest that a quantitative comparison of light curve structure is very useful to provide constraints for the input physics to the stellar pulsation models.
Asteroseismology in the BINA context
Authors: Mazumdar Anwesh , Mookerjea Bhaswati , Ranadive Pritesh
Published: January 2022

The scope of asteroseismic studies within the Belgo-Indian Network for Astronomy and astrophysics (BINA) is explored. The main strands of current research in asteroseismology of solar-type stars are outlined. While it is obvious that it would be difficult to match the quality of the space-based seismic data on such stars with ground-based telescopes, the possibility of contribution to supplemental non-seismic data is considered. New calibrations of colour-temperature relations using archival data are presented. It is proposed that with similar calibrations with BINA-based photometric data in the future, it would be possible to provide accurate estimates of effective temperatures of solar-type stars that would be useful in asteroseismology of such stars.
Detecting Outliers in SDSS using Convolutional Neural Network
Authors: Sharma Kaushal , Kembhavi Ajit , Kembhavi Aniruddha , Sivarani Thirupathi , Abraham Sheelu
Published: January 2022

We propose an automated algorithm based on Convolutional Neural Network (CNN) for the detection of peculiar objects in large databases using their spectral observations. A convolutional neural network is a class of deep-learning algorithms which allows the detection of significant features/patterns in sequential data like images, audio, time-series etc. by applying convolutional neurons (kernels) along the sequence. For detecting unusual spectra, we use eight-layer deep convolutional network with autoencoder architecture on ~ 60,000 spectra collected from the Sloan Digital Sky Survey. The training of the network is done in an unsupervised manner. We show that the trained network is able to retrieve the spectra of rare objects from a large collection of spectra. Such algorithms can easily be rescaled to other surveys and therefore can serve as a potential component of the data reduction pipelines for automatically detecting spectra with unusual features and recovering defective spectra.

We present here I-band time-series photometric studies of a few very low-mass stars (VLMs) and brown dwarfs (BDs) in the young (age of 2-3 Myr) IC348 star-forming region in the Perseus Molecular Cloud. Our main aim is to explore the fast rotating (of time scale of a few hours) BDs and VLMs in the I-band. From our preliminary results, we find significant variability in the young M5 dwarf 2MASS J03443896+3203196 with a rotation period of 16.037 hours.
Le potentiel de la géothermie peu profonde dans la transition énergétique
Authors: Dassargues Alain
Published: January 2022

Traditionnellement, seule la géothermie profonde était envisagée. Actuellement, les différentes formes de géothermies peu profondes et de faible enthalpie sont plus accessibles car elles présentent moins de risques financiers et environnementaux. Leur multiplication, notamment pour couvrir les besoins énergétiques de (gros ou nombreux) bâtiments, permet à ces systèmes de participer pleinement à la transition énergétique en cours. Ces systèmes géothermiques peu profonds ne requièrent aucune anomalie du gradient géothermique local. Néanmoins, lorsque des pompages et réinjections sont envisagés dans des aquifères peu profonds, les conditions hydrogéologiques influencent fortement l’efficacité (rendement) et la durabilité des systèmes installés mais aussi leur éventuel impact sur la quantité et la qualité des ressources en eaux souterraines. Les différents types de systèmes géothermiques peu profonds sont brièvement présentés, puis l’accent est mis sur les systèmes par doublets en aquifère et sur les anciennes mines.
Transport of angular momentum by waves in stars
Authors: Belkacem Kevin
Published: January 2022

Transport of angular momentum is a long-standing problem in stellar physics which recently became more acute thanks to the observations of the space-borne mission Kepler. Indeed, the need for an efficient mechanism able to explain the rotation profile of low-mass stars has been emphasized by asteroseimology and waves are among the potential candidates to do so. In this article, our objective is not to review all the literature related to the transport of angular momentum by waves but rather to emphasize the way it is to be computed in stellar models. We stress that to model wave transport of angular momentum is a non-trivial issue that requires to properly account for interactions between meridional circulation and waves. Also, while many authors only considered the effect of the wave momentum flux in the mean momentum equation, we show that this is an incomplete picture that prevents from grasping the main physics of the problem. We thus present the Transform Eulerian Formalism (TEM) which enable to properly address the problem.
Atomic diffusion across the HR diagram
Authors: Richard Olivier
Published: January 2022

It is clear that in order to explain many observed stellar phenomena, atomic diffusion must be included in stellar models. The effects of atomic diffusion are not limited to the surface abundances as we will see, it occurs in stars from the surface to the center and even if these effects are reduced in the external layers by other transport processes it remains in the center. We will also see that the induced chemical stratification has a strong impact on the stellar opacity.
Probing core overshooting using asteroseismology
Authors: Deheuvels Sébastien
Published: January 2022

Modeling properly the interface between convective cores and radiative interiors is one the most challenging and important open questions in modern stellar physics. The rapid development of asteroseismology, with the advent of space missions partly dedicated to this discipline, has provided new constraints to progress on this issue. We here give an overview of the information that can be obtained from pressure modes, gravity modes and mixed modes. We also review some of the most recent constraints obtained from space-based asteroseismology on the nature and the amount of mixing beyond convective cores.
Polymer-based nanoinsecticides: current developments, environmental risks and future challenges. A review
Authors: Sun Changjiao , Zeng Zhanghua , Cui Haixin , Verheggen François
Published: January 2022

Introduction. The rapid development of the nanotechnology industry opens new perspectives for modern crop protection strategies. This review summarizes and discusses the use of polymers as nanocarriers of insecticides. They are expected to ensure a higher level of protection for humans and the environment, while ensuring good efficacy of the active ingredient. Literature. Some of the synthetic polymers (including polyethylene glycol, polylactic acid, polycaprolactone and polyhydroxybutyrate), which are widely used in pharmaceutical or cosmetic areas, can be employed as insecticide carriers. But natural polymers (including chitosan, alginate, cellulose, starch and cyclodextrins) are receiving increasing attention because of their environment-friendly properties. The polymeric materials can be prepared in various types of tridimensional structures, among which nanocapsule, nanosphere, micelle, nanogel and nanofiber are the most common for the delivery of the active ingredient. The environmental risks of polymer-based nanoinsecticides are highlighted, together with the main challenges that must be solved before future marketing. These challenges include the reduction of their production cost and assessment of their performance, especially at the field level. New protocols for characterizing, detecting and quantifying are also urgently required. Conclusions. Polymer-based nanoformulations appear to be promising for target release of active ingredients while reducing excess runoff. In order to facilitate the development of new beneficial products, collaboration among countries around the world is required.

Description of the subject. Cheese is a vector of Listeria monocytogenes. By default, European Commission imposes its absence in cheese before sales, but fixes pH and water activity thresholds below which it cannot grow. Objectives. To study pH and water activity of Belgian cheeses and the prevalence of L. monocytogenes in these products. Method. Salt content, pH and water activity of 134 cheeses were determined. Absence of L. monocytogenes in 25 g of cheese was also checked. Results. Three samples had pH or water activity under threshold values from regulation. Nevertheless, all unripened cheeses were acid in comparison with data from foreign countries. Listeria monocytogenes was isolated from 1.49% of the samples. Conclusions. Belgian artisanal cheeses could allow the growth of L. monocytogenes, and the bacterium was isolated from two samples. Further experiments should be performed to understand the fate of the pathogen in these products.

Published: January 2022

Description of the subject. Commercialization requires the storage of meat for a period of time according to the distribution and supply chain, usually under refrigeration and vacuum packaging. During this stage, many biochemical reactions can modify the sensory and physicochemical properties of meat. Proteolysis is one of the most important of these reactions as proteins are the building blocks of muscle, and their degradation affects tenderness. Objectives. The objectives of this study were to use multiple factorial analyses to correlate the physicochemical, sensory, and proteolytic changes in ovine meat during refrigeration. Method. Each loin was separated and randomly assigned to day 3, 5, or 14. Sensory panel evaluated the meat for appearance, odor and texture parameters. Warner-Bratzler shear force and texture profile analysis were evaluated. Similarly, protease activity was evaluated. Samples for 2D-electrophoresis and western blotting were collected at days 3, 5, and 14 post mortem. The results were analyzed by multiple factorial analyses. Results. The relative protein levels of desmin, vinculin, and myosin were found to decrease with time. Multiple factor analysis showed that the Warner-Bratzler shear force (WBSF) was highly correlated with the relative desmin concentration, the relative vinculin concentration, and acidic protease activity. The activities of acidic and neutral proteases were positively correlated with myosin level on day 3, but were negatively correlated with manual tenderness and myosin level on days 5 and 14. Conclusions. Therefore, desmin, myosin and vinculin, which correlate with sensory and physicochemical parameters during refrigerated storage, may prove useful as markers for tenderness.

Published: January 2022

Description of the subject. Despite the importance of tomato in Central Africa, little is known about the weed flora occurring in tomato crops in this part of the world. Objectives. We aimed to provide a comprehensive description of the weed flora found in tomato crops in the mountainous region of South Kivu, DR Congo. Method. Floristic inventories were made in four cultivation zones of the Kabare territory, South Kivu. Results. In total, 79 species (belonging to 64 genera and 31 families) were recorded. The most species-rich families were Asteraceae and Poaceae. Therophytes and geophytes were the dominant life forms. Weed diversity was not significantly different between sites but species composition varied considerably, likely in relation to soil type. Based on the frequency and the abundance, the most problematic weeds were Commelina benghalensis, Galinsoga quadriradiata, Commelina diffusa, Galinsoga parviflora, Bidens pilosa, Oxalis debilis and Digitaria velutina. Conclusions. The weed flora in tomato fields of the mountainous regions of DR Congo is diversified, but only a few cosmopolitan species are problematic.

Description du sujet. La baisse et l’irrégularité des pluies modifient considérablement les saisons culturales, ce qui oblige les paysans à une restructuration du calendrier agricole en s’appuyant sur les savoirs locaux. Objectifs. L’objectif de cette étude est de valoriser les savoirs locaux utilisés par les paysans dans la gestion du calendrier agricole. Les objectifs spécifiques sont, d’une part, d’inventorier les indicateurs biophysiques utilisés dans la définition des calendriers culturaux et, d’autre part, de déterminer les espèces végétales repères communes aux trois zones écologiques étudiées. Méthode. Ce but fut atteint grâce à des interviews semi-directes individuelles et via des focus groups auprès d’un échantillon de 689 agriculteurs répartis dans 65 localités. Résultats. Il ressort que la totalité des paysans enquêtés utilisent des marqueurs temporels dans la définition des calendriers culturaux, surtout dans la reconnaissance des débuts de saison pluvieuse (période de semis) et de saison sèche (période de récolte). Il s’agit principalement des indicateurs biologiques tels que la phénologie des plantes (en saison sèche : Triumfetta rhomboidea Jacq. [floraison], Spathodea campanulata P.Beauv. [floraison], Vitellaria paradoxa C.F.Gaertn. [fructification] et en saison pluvieuse : Millettia thonningii (Schum. & Thonn.) Baker [floraison], V. paradoxa [floraison], Delonix regia (Hook.) Raf. [floraison], Ceiba pentandra (L.) Gaertn. [éclatement du fruit]). Au total, 67 espèces végétales ont été recensées comme indicateurs des variations des saisons agricoles. Outre les espèces végétales, la migration saisonnière des oiseaux (73 %), l’apparition des insectes (48 %), mais aussi des indicateurs abiotiques comme le sens du vent (100 %), les observations des étoiles (82 %) et le déplacement des nuages (69 %) sont utilisés comme repères dans la gestion des périodes agricoles. Conclusions. La connaissance de ces signaux permet aux paysans d’anticiper sur d’éventuelles variabilités climatiques et suivre, diriger et adapter leurs activités culturales. Ces savoirs locaux constituent dès lors une aubaine pour l’adaptation aux changements climatiques.

Background: The 2019 Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) was initially declared as a health emergency by the World Health Organization, which eventually progressed to a pandemic. To date, more than 213,752,662 people worldwide have been infected by SARS-CoV-2, resulting in 4,459,381 deaths. Various clinical characteristics and studies have been described regarding SARS-CoV-2. Case Presentation: There are very few reports about cases of patients with a COVID-19 infection accompanied by cerebral infarction. In this report, we present the case of a 74-year-old patient who was infected with SARS-CoV-2 in late January and later developed a cerebral infarction. Following appropriate treatment, the patient recovered and was discharged from hospital on April 3, 2020. Follow-up after 10 months revealed that the patient was living a normal life without any obvious sequelae. Conclusions: This paper presents the management and treatment of an elderly patient who suffered from COVID-19 associated with a cerebral infarction. Following discharge from Huangshi Central Hospital, the patient lived a normal life without any clinical sequelae. We believe that the early introduction of traditional Chinese medicine played an important role in the treatment of COVID-19. We aim to spread awareness on COVID-19 and to suggest a therapy for COVID-19 patients with a concomitant cerebral infarction.

Proline metabolism plays an essential role in tumor development; however, its underlying mechanism in CRC remains elusive. B7-H3, an immune checkpoint member of the B7 immunoregulatory family, is aberrantly overexpressed in a wide variety of malignancies and is associated with a poor prognosis. In this study, we found that overexpression of B7-H3 effectively enhanced proline consumption rate and reduced glutamate production, while knockout of B7-H3 had inverse effects. Moreover, we also identified that B7-H3 increased proline consumption and decreased glutamate production by promoting the expression of Pyrroline- 5-carboxylate reductase 1 (PYCR1) in CRC cells and that PYCR1 is a crucial mediator of B7-H3-induced CRC proliferation and migration. Overexpression of PYCR1 or treatment of cells with PYCR1 inhibitors could reverse B7-H3-induced proline metabolism and B7-H3-induced tumor cell proliferation and migration. Furthermore, we confirmed the positive correlation between B7-H3 and PYCR1 expression in tumor tissues of CRC patients. Collectively, the present study highlighted a previously unrecognized mechanism of B7-H3-mediated rewiring of proline metabolism through increased expression of PYCR1 in CRC cells. These findings suggested that B7-H3 may serve as a novel prognostic factor and a promising therapeutic target for CRC.

As a case study, the paper was planned and applied in order to identify nutrition characteristics of children with moderate and severe intellectual disability, some nutrition habits, and food consumption frequencies and treatments of families towards their nutrition. The sample of this research is included by 82 children and their parents at the age of 5-18 with moderate and severe intellectual disability who continue their education at Aksaray. Data of the research were collected between January-February 2018 from mothers by using questionnaires in face to face interview and some of the questionnaires were distributed and collected after making necessary explanations to some of them. Descriptive statistical analyzes such as percentage (%) and frequency (n) were made by SPSS package program. Chi-square (χ2) significance test was used for the statistical evaluation of the data collected of this search. In evaluating the food consumption frequency, a scoring system was used, using the formula T = 5T1 + 4T2 + 3T3 + 2T4 + 1T5. In order to compare foods with each other in terms of frequency of consumption, the percentage is calculated between the total score set for each food item and the highest total score that if this food consume every day. 73.2% of the participants were male and 26.8% were female. Age of the children ranged from 4 to 18, with an average of 10.71 ± 0.52 years. In the study, 46.3% of mothers stated that they can eat their own meal when they were asked "how does your child consume their meals?” 46.3% of them pointed that they sometimes eat with support of someone else, 7.4% stressed that they eat sometimes themselves and sometimes with the support of others. Mothers of 44 children who were unable to feed themselves stated that they can’t reach the independent nutrition stage. 39.1 % of them told that they polluted the environment, 37.0 % indicated that they cannot keep the spoon, and 23.9% complained that it took too much time for them.

Accounting for Justice: Citizen Public Debt Audits and the Case of Puerto Rico
Authors: Wiedenhoft Murphy Wendy
Published: January 2022

A Citizen Public Debt Audit (CPDA) is an emancipatory praxis that can mobilize citizens to make legible public debt that has been accrued in their name. Ideally, it should hold creditors accountable for debt that is determined to be odious. This study examines the public debt crisis in Puerto Rico to illustrate the historically unjust circumstances under which public debt was accumulated on the island in the context of US federal taxation and economic policies. It explains how citizens are mobilizing via a CPDA to make these circumstances legible and argues that citizens should not be obliged to service debt that was accrued contrary to their own welfare, especially if conditions of repayment threaten their current and future well-being.
The Mystery of National Identity of Chinese International Students amid the COVID-19 Pandemic: The Role of Western Neo-racism and Chinese Nationalism
Authors: Long Fei
Published: January 2022

The research aims to explore the changes of national identity among Chinese international students in the odd social context of the global pandemic. By conducting semi-structured interviews with 10 Chinese undergraduate and postgraduate students in a prestigious university located in London, UK, the study provides evidence of Western neo-racism against Chinese students and the rise of Chinese nationalism. More significantly, it is found that Western neo-racism and Chinese nationalism have a push and pull effect on the national identity enhancement of Chinese international students. The participants revealed that bottom-up popular nationalism is more than a shadow of top-down state nationalism in China, and is more influential on students’ national identity formation. The research also discusses the implications of these findings, limitations and future research directions.

Abundant low-cost oil palm mesocarp fibre could serve as a potential feedstock for the
production of oligosaccharides which may have prebiotic properties. Thus, a study was
carried out to determine the ability of saccharified oil palm mesocarp fibre (OPMF) to
support the growth of a probiotic microorganism (Lactobacillus rhamnosus GR-1). The
saccharified OPMF was produced using different saccharification times (1, 3 and 6 hrs)
while fermentation of the saccharified OPMF with L. rhamnosus GR-1 was carried out for
0, 12 and 24 hrs. Growth of L. rhamnosus GR-1 was measured based on OD600 using a
UV-spectrophotometer along with the pH of the growth media. The results showed a
significantly higher (p<0.05) growth of L. rhamnosus GR-1 with increasing
saccharification time and fermentation time. Increased saccharification time of up to 6 hrs
also resulted in a higher variety of oligosaccharides compared to 1 hour and significantly
reduced (p<0.05) pH of the growth media. The use of saccharified OPMF produced
comparable growth of L. rhamnosus GR-1 with significantly lower (p<0.05) pH compared
to using fructooligosaccharide in the growth media. The results showed the ability of
saccharified OPMF to support the growth of probiotic L. rhamnosus GR-1.
The Peterson Case and its Impact on the Rules in Ben Nevis
Authors: Coleman James
Published: January 2022

This article revisits and builds upon Professor Prebble's 2006 book chapter "The Peterson Case and its Impact on the Rules in BNZ Investments Ltd and Cecil Bros", considering the ways in which the Peterson case has influenced the leading 2009 New Zealand tax avoidance case of Ben Nevis. The article argues that Ben Nevis actually follows Peterson in two ways. First, it adopts the analysis of both the majority and the minority judgments in Peterson to the effect that the general anti-avoidance provision only applies when the purpose of the particular provision has been thwarted. Secondly, it uses the minority's less judicial approach in considering whether the purpose of the specific provision has been complied with or not. The minority allowed a greater sweep of material to be relevant and inform that decision than the majority did. The majority looked only to the contractual rights and obligations created.

Authors: Winaryati Eny , Munsarif Muhamad , Mardiana Mardiana , Suwahono Suwahono
Published: January 2022

This article discuss about the RD&D stages that will be used to develop the MESp digital platform. This RD&D stage is done in stages and cyclically. Each phase is evaluated, with the hope that a valid, practical and effective product will be produced, and has been tested. The development of the MESp digital platform uses the RD&D method, using the literature review method. The RD&D phases consist of: Research (Analysis, Define), Development (Design, Demonstration, Development), Diffusion (Delivery, Diffusion, Adoption). Each phase is equipped with sub-activities that must be done. Each phase evaluates PAI (Purphose, Activities, Interim Product). Users are allowed to move to the next phase, when an evaluation has been produced that can answer: the achievement of its objectives, the activities that have been done, and the temporary products produced. Users are given the freedom to add sub-activities from each phase, if that necessary and for a clear reason.
