Evapotranspiration (ET) estimation is essential for adequate management of water resources. The main ways to quantify ET are based on the use of field sensors, class A tanks, Bowen's ratio method, turbulent vortex correlation analysis, use of lysimeters, and through Remote Sensing (RS), which allows estimating biophysical parameters based on satellite images. The objective of the research was to determine the effective evapotranspiration (ETe) of cotton plantations irrigated with a centre pivot, using the Surface Energy Balance Algorithm for Land (SEBAL), Mapping Evapotranspiration at High Resolution and with Internalized Calibration (METRIC) and Simple Algorithm for Evapotranspiration Retrieving (SAFER) methods. Comparisons were made for three agricultural years, using the R², RMSE, MAE, MBE and R statistics. The best performances in the crops were obtained with the SEBAL vs. SAFER models, which presented mean values of 0.54, -0.30 and 0.31 mm d-1 in RMSE, MBE and MAE, respectively. The data obtained by all three models can be applied to estimate ETe in irrigated cotton plantations and, consequently, their results can assist in irrigation management and in crop treatments

Detasseling is an essential practice in maize seed production to obtain hybrids. Due the difficulty in carrying out the detasseling in a standardized way, the objective of this study was to evaluate the yield and physiological quality of maize seeds after using detasseling techniques in two cropping seasons. The experiment was carried out in Pitangueiras - PR, using corn progenitors of the commercial hybrid Balu 761. The experimental design was randomized blocks with 4 replications. The factorial scheme was 6 × 2, with 6 detasseling techniques: removal of the tassel only (D0); tassel removal + 1 sheet (D1); tassel removal + 2 leaves (D2); tassel removal + 3 leaves (D3); tassel removal + 4 leaves (D4); and tassel removal + 5 leaves (D5), and 2 cropping seasons: cropping season 1 (2014) and cropping season 2 (2015). The variables analyzed were: seed yield (kg ha-1), germination (%) and seed vigor from the accelerated aging (%) and cold test (%). The results showed that detasseling of maize progenitors of the Balu 761 hybrid must be carried out with the removal of the tassel only, considering that the removal of leaves during this practice is capable of reducing seed yield by up to 25%. The removal of the tassel with up to five leaves does not affect the physiological quality of the maize seeds. The cropping season influenced the seed yield, as well as seed germination and vigor from the cold test

Published: July 2023

The decline in soil fertility and productivity has been a problem in cassava cultivation. The plant biomass transported from cassava fields at harvest losses several nutrients. This study aimed to determine the nitrogen (N), phosphorous (P), and potassium (K) nutrient content of plant parts of cassava and the nutrient balance. The cassava varieties of UK1 Agritan, Malang 4, Barokah, UJ-5, and Mangu were grown in 3 replications using a completely randomized design. Two harvesting methods, the farmer’s harvest method (FHM) and the harvest method introduced (HMI) were applied. The FHM transported all tuber and other plant parts biomass, and the HMI transported all tuber and 60% of the stem from the cassava field. Each replication was one row of plants 20 m long and a spacing of 1 m. The cassava fertilized at 169 kg N, 84 kg P, and 170 kg K per hectare in grooves around the plant. The leaves of the five varieties contain higher N, P, and K than the petiole, stem, and tuber. At harvest, the N and P nutrients were mainly transported from the leaves, and K nutrients from the tubers. For a yield of 40 tons ha-1 fresh tubers, the FMI resulted in an average nutrient balance for N (-222 kg ha-1) and K (-103 kg ha-1) and P (48 kg ha-1), the HMI resulted in an average nutrient balance of 305 kg N, 56 kg P, and 82 kg K per hectare. The HMI is recommended for sustainable soil fertility and high productivity of the cassava field

Published: July 2023

This study evaluated responses of modern and local Thai rices to find varieties that are suitable for growing in water-limited areas under aerobic and anaerobic soils. Nine rice varieties and two soil water conditions were arranged as a factorial design in a completely random design (CRD) with three replications. The agronomic traits that were measured consisted of 50% flowering date, plant height, yield components, harvest index (HI), and grain yield plant-1. Growing rice under aerobic soil significantly reduced plant height, yield components and grain yield, compared with anaerobic soil. However, the reduction differed depending on the variety. The modern rice varieties tend to be more adapted to the aerobic soils, compared to local. Modern rice varieties, RD29, RD49, and RD57, and a local rice variety, Chiang Phatthalung, tend to be better adapted under aerobic soil. These were clearly indicated by the smallest reduction in some agronomic traits under aerobic compared to anaerobic conditions. The plant height of RD57 was 107.93/ 104.53 cm in anaerobic and aerobic, respectively. The tiller number plant -1 in RD57 was 15.2/ 8.8; panicle number plant -1 in RD57 was 14.67/8.7 and in RD29 12.6/7.7; spikelet number plant -1 in RD57 was 188/203 and RD49 was 185/189; filled grain plant -1 in RD57 was 166.8/161; empty grain plant -1 in Chiang Phatthalung was 76.6/45.87; filled grain (%) in Chiang Phatthalung was 57.3/62.1. A highly significant correlation was found between grain yield and the number of panicle plants-1 (R=0.75; P<0.001) under non-flooded conditions, which indicated that grain yields under aerobic soil largely depended on panicle initiation. Therefore, the panicle initiation stage should first be concentrated under water shortage. Thailand comprises a wide diversity of rice. Therefore, more varieties of both modern and local Thai rice should be studied further

Intensive breeding and artificial selection of the desired traits in maize landraces through domestication have created modern maize, which needs a great technological contribution for optimal productive development. However, the narrowing of the genetic bases of maize made it difficult for traditional farmers to access productive genetic material that maintains the genotypic and phenotypic diversity capable of ensuring productive sustainability. Thus, objective of the study was to evaluate the variability and production gain in morphoagronomic characters of Nawa Sheki landraces maize after two mass selection cycles. The work was carried out in the experimental area of the Federal University of Acre, where two cycles of mass selection were applied on variety Nawa Sheki, in periods 2018/2019 and 2019/2020. The characteristics evaluated were: plant height, ear insertion height, ear length, ear diameter, number of rows of grains, number of grains per row, ear mass and grain mass. Data were submitted to descriptive analysis, with presentation of the histogram of frequency, asymmetry, kurtosis and Shapiro-Wilk test for the general population in both cycles. For the selected population, the following were obtained: mean, coefficient of variation, amplitude, minimum and maximum values and population variance in each cycle. The genetic parameters were selection differential for both cycles, production gain with selection and realized heritability of the first cycle. The choice of individuals in both cycles of mass selection was based on the ranking of the best values of the evaluated characteristics. The two cycles of mass selection provided high variability in the traits with the presence of superior phenotypes. Still, mass selection stabilized values for plant height, ear insertion height, followed by production gains for number of grains per row and ear mass.

A wash-free ER marker to monitor micropolarity during ER stress and visualize ER- Golgi transport
Authors: Dutta Tanoy , Nigam Aditya , Minocha Shilpi , Koner Apurba Lal
Published: July 2023

Cellular stress plays a key role to regulate and maintain organismal as well as microenvironmental homeostasis. The stress-induced response is also reflected in the micropolarity of any specific cellular compartment, which is essential to be quantified for early disease diagnosis. Alongside, coming up with a biocompatible small-molecule fluorophore NBD-Oct for exclusive endoplasmic reticulum (ER) localization simply driven by its hydrophobicity, in this contribution, we present a quantitative study of micropolarity alteration inside the ER during G1/S and G2/M phases. The cell cycle arrests caused by the induced ER stress led to the enhancement of the ER micropolarity in cells. NBD-Oct is selected among a series of analogous probes based on its fastest diffusion properties demonstrated by fluorescence recovery after the photobleaching experiment. The probe is a versatile staining agent as it could efficiently stain the ER in live/fixed mammalian cells, isolated ER, Caenorhabditis elegans, and mice tissues. Finally, a well-known biological event, ER to Golgi transport is also visualized by live-cell fluorescence microscopy using this probe. We believe this exhaustive investigation of micropolarity using NBD-based dye provides a new avenue to study ER stress that may unravel a deeper understanding of proteostasis in model systems and potentially even fixed patient samples.

Authors: M R Ranju , D Kesavan
Published: July 2023

This paper aims to study the effect of shot peening on the Rolling Contact Fatigue (RCF) life of EN 31 Steel subjected to a pure rolling condition. Tests were carried out under lubricated contact conditions using a two-disc on-cylinder test rig. The orthogonal stress distributions and depth of deformation zones under static loading conditions were calculated using an elastic model by Finite Element Analysis (FEA) method. Shot peening increased the surface hardness by 20 % and imparted residual stress, which resulted in a 2-fold improvement of life. The depth of origin of the crack from the sub-surface was found to be in good agreement with the depth of maximum shear region obtained from the finite element model.

SELP (CD62P) is a differentially expressed gene in brain metastatic human breast cancer.
Authors: Mamoor Shahan
Published: July 2023

Metastasis to the brain occurs in a significant fraction of patients with breast cancer (1-3). We mined published RNA-sequencing and microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that selectin P, encoded by SELP, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. SELP mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of SELP in primary tumors was correlated with overall and recurrence-free survival. Thus, P-selectin, L-selectin (6) and E-selectin (7) are each among the genes whose expression is most different in the brain metastasis of patients with breast cancer. Selectin down-regulation is likely a requisite step during metastasis to the central nervous system in human breast cancer.

HUMAN TRAFFICKING IN INDONESIA BETWEEN BUSINESS AND HUMANITARIAN CRIME
Authors: naryono endang
Published: July 2023

The crime of human trafficking during the 2018-2022 period is very worrying and endangers national security, the policies taken by the government are not very significant for cases of human trafficking. The high number of unemployed, limited employment opportunities resulting in an increasing poverty rate is one of the factors that has resulted in high public interest in working abroad even though they work in the non-formal sector without having high knowledge or sufficient competence to work abroad. This condition is exploited by perpetrators of human trafficking crimes by giving lures or promises to get high salaries while working abroad so that they can improve their economic life. Low education causes them to be deceived by perpetrators of human trafficking crimes, the fact is that when they arrive, many are not employed. humane, unpaid work, even made into women commercial sex workers which is not surprising that many illegal migrant workers end up dying. The increasing prevalence and intensity of human trafficking crimes is caused by the still weak resources owned by the government and it is then suspected that there are law enforcement officials involved in supporting human trafficking crimes in Indonesia.
SLAMF2 is differentially expressed in central nervous system metastasis.
Authors: Mamoor Shahan
Published: July 2023

Metastasis to the brain occurs in a significant fraction of patients with breast cancer and lung cancer (1-3). We mined published RNA-sequencing and multiplexed gene expression data (4, 5), comparing primary and brain metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the CNS. We found that SLAMF2, encoded by CD48, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. Multiplexed gene expression data (5) revealed conserved differential expression of CD48 in CNS metastasis in patients with lung cancer. CD48 mRNA was present at decreased quantities in metastasis to the brain in humans with breast cancer. Expression of CD48 in primary tumors of the breast was correlated with overall and recurrence-free survival. Modulation of CD48 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with cancer of the lung and breast.

Authors: Ermiş Seda , Demirci Murat
Published: July 2023

In this study, various Rectangular Microstrip Antenna (RMA) designs operating at 28 GHz frequency for 5G-communication system are performed. All designs are generated and analyzed using a 3D electromagnetic simulation program, ANSYS HFSS (High-Frequency Structure Simulator). Single and array type RMA designs are constructed by using non-contact inset-fed feeding technique. Subsequently, the bandwidth of RMAs is increased by slotting on the ground surface, and adding a parasitic element to the antenna structure. Because of these analyses, for single type RMA, the bandwidth increases from 2.09 GHz to 3.45 GHz. Moreover, for 1 × 2 and 1 × 4 array type RMAs, very wide bandwidths of 7.53 GHz and 4.53 GHz, respectively, are obtained by applying bandwidth enhancement techniques. The success of the study has been demonstrated by comparing outputs of the designs with the some similar, experimental or simulation studies published in the literature.

This paper aims to describe the role of teachers in providing protection to children from the point of view of drug law policy by formulating the problem of how the protection is by teachers children who abuse drugs. This study uses a qualitative research methodology. This type of research is under the umbrella of library research, namely research conducted through library research. The findings of this study are used to guide efforts to transfer children from the formal criminal justice system to non-formal criminal justice systems in order to keep them from becoming addicted to drugs. One of the distinctive aspects of this diversion technique is the participation of multiple stakeholders. Diversion differs from mediation in that it involves more than just the parties to the conflict; that mediation only involves conflicting parties, diversion also involves other parties such as community leaders, parents (children of perpetrators), religious leaders, law enforcement officers, and teachers. But among all those involved, the instructor was the one who had a significant impact. Because teachers function as surrogate parents, have more time with children than other adults, and help shape children's personalities.

Surah 5 of the Qurʾān: The Parting of the Ways?
Authors: Lindstedt Ilkka
Published: July 2023

Was an Islamic identity, shared by the in-group members and distinct from other religious categorisations, operative already during the time of the Prophet Muḥammad (d. 632)? This article looks at surah 5 of the Qurʾān, titled al-Māʾida, as a locus where the discourse of ‘the parting of the ways’ might be found. If a reified group of Muslims, with their religion Islam, distinct from Jews and Christians, can be supposed to have existed during the time of the Prophet, it is in al-Māʾida where this should be the easiest to perceive, but, I argue, this is not the case.

The development of cost-effective, biocompatible soft wound dressings is highly desirable; however, conventional dressings are only designed for flat wounds, which creates difficulty with promising healing efficiency in complex practical conditions. Herein, we developed a tough, adhesive biomimetic hyaluronic acid methacryloyl hydrogels composed of chemically crosslinked hyaluronic acid methacryloyl (HAMA) network and poly(N-hydroxyethyl acrylamide) (PHEAA) network rich in multiple hydrogen bonding. Due to the multiple chemical crosslinking sites (acrylamide groups) of HAMA; the bulk HEMA/PHEAA hydrogels presented significant enhancements in mechanical properties (∼0.45 MPa) than common hyaluronic acid hydrogels (<0.1 MPa). The abundant hydrogen bonding also endowed the resultant hydrogels with extremely high adhesiveness on many nonporous substrates, including glass and biological tissues (e.g., heart, liver, lung, kidney, stomach, and muscle), with a considerable interfacial toughness of ∼1432 J m−2. Accordingly, since both natural hyaluronic acid derivative polymers and hydrophilic PHEAA networks are highly biocompatible, the hydrogel matrix possesses good blood compatibility (<5% of hemolysis ratio) and satisfies the general dressing requirements (>99% of cell viability). Based on these physicochemical features, we have demonstrated that this adhesive hydrogel, administered in the form of a designed patch, could be applied to wound tissue healing by promoting epithelialization, angiogenesis, and collagen deposition. We believe that our proposed biomimetic hydrogel design holds great potential for wound repair and our developed HAMA/PHEAA hydrogels are extremely promising for the next-generation tissue healings in emergency situations.
The effects of P2Y12 adenosine receptors’ inhibitors on central and peripheral chemoreflexes

Published: July 2023

Introduction: The most common side effect of ticagrelor is dyspnea, which leads to premature withdrawal of this life-saving medication in 6.5% of patients. Increased chemoreceptors’ sensitivity was suggested as a possible pathophysiological explanation of this phenomenon; however, the link between oversensitization of peripheral and/or central chemosensory areas and ticagrelor intake has not been conclusively proved.

Methods: We measured peripheral chemoreceptors’ sensitivity using hypoxic ventilatory response (HVR), central chemoreceptors’ sensitivity using hypercapnic hyperoxic ventilatory response (HCVR), and dyspnea severity before and 4 ± 1 weeks following ticagrelor initiation in 11 subjects with chronic coronary syndrome undergoing percutaneous coronary intervention (PCI). The same tests were performed in 11 age-, sex-, and BMI-matched patients treated with clopidogrel. The study is registered at ClinicalTrials.com at NCT05080478.

Results: Ticagrelor significantly increased both HVR (0.52 ± 0.46 vs. 0.84 ± 0.69 L min-1 %−1; p < 0.01) and HCVR (1.05 ± 0.64 vs. 1.75 ± 1.04 L min−1 mmHg−1; p < 0.01). The absolute change in HVR correlated with the change in HCVR. Clopidogrel administration did not significantly influence HVR (0.63 ± 0.32 vs. 0.58 ± 0.33 L min-1%−1; p = 0.53) and HCVR (1.22 ± 0.67 vs. 1.2 ± 0.64 L min−1 mmHg−1; p = 0.79). Drug-related dyspnea was reported by three subjects in the ticagrelor group and by none in the clopidogrel group. These patients were characterized by either high baseline HVR and HCVR or excessive increase in HVR following ticagrelor initiation.

Discussion: Ticagrelor, contrary to clopidogrel, sensitizes both peripheral and central facets of chemodetection. Two potential mechanisms of ticagrelor-induced dyspnea have been identified: 1) high baseline HVR and HCVR or 2) excessive increase in HVR or HVR and HCVR. Whether other patterns of changes in chemosensitivities play a role in the pathogenesis of this phenomenon needs to be further investigated.

Tous les instruments internationaux relatifs aux droits des peuples autochtones font référence à la relation spéciale qui existe entre les peuples autochtones et la terre. Afin de reconnaître les particularités et les besoins des autochtones, la Cour interaméricaine des droits de l’Homme a interprété l’article 21 sur le droit de propriété en y intégrant les caractéristiques de la propriété telle que conçue par les peuples autochtones. La Cour a enrichi son contenu et développé des obligations concrètes que l’État doit satisfaire pour se conformer à la Convention américaine relative aux droits de l’Homme et rendre effectif le droit à la propriété pour ces groupes.
La dénaturation manifeste du statut de forêt de protection par le décret du 6 avril 2018
Authors: Schmit Laura
Published: July 2023

Le statut de forêt de protection de 1922 symbolise l’accomplissement d’un régime forestier spécial strict et uniquement protecteur et conservateur des massifs forestiers classés. La logique originelle du classement était liée à la protection de l’Homme par les forêts situées en montagne, le long du littoral et des fleuves, contre les aléas naturels tels que l’érosion, les avalanches et glissements de terrain. La vision du statut de forêt de protection a cependant évolué à la suite de la création, en 1976, de nouveaux motifs permettant de classer en forêts de protection des forêts dites périurbaines, modifiant ainsi sensiblement l’application de la loi relative aux forêts de protection. Cette évolution du statut a de ce fait entraîné une confusion entre les deux objets concernés par la loi que sont les forêts de montagne et les forêts périurbaines, ouvrant ainsi la voie à des transformations plus profondes du régime forestier spécial. C’est alors, par le récent décret du 6 avril 2018, que la logique économique s’est définitivement implantée au sein de ce régime, assouplissant la rigidité de ce dernier au détriment de l’efficacité de la fonction de protection de ce statut.
Immigrant Entrepreneurship in Côte d'Ivoire: Socio-demographic Profile and Specific Characteristics of Nigerian and Nigerian Immigrant Entrepreneurs in Yopougon (Côte d'Ivoire)
Authors: Antoine Kobena Kouadio
Published: July 2023

The socio-economic development of Côte d'Ivoire thanks to the coffee-cocoa pairing in the 1980s led to an increase in the flow of immigrants throughout the country. Unfortunately, this economic and social growth could not be sustained over a long period. The economic crisis that hit the country was immediately accompanied by austerity policies steered by international financial institutions such as the World Bank and the International Monetary Fund (IMF). The immediate consequence of the country's economic constraints has been the destructuring of the labour market, particularly in terms of supply and demand. As a result, the majority of immigrant populations are affected in the same way as nationals by the precariousness of their jobs. Faced with this "unexpected" situation, private or individual initiatives have been taken by immigrant populations to escape and also to seize existing opportunities. Yopougon, Abidjan's largest commune, has seen its commercial spaces "invaded" by Nigerians who have set up micro-businesses. The aim of this article is to establish the socio-demographic profile of 150 immigrant entrepreneurs based in commercial spaces and to identify the specific characteristics of immigrant entrepreneurship in these communities in Yopougon. The study shows that the majority of entrepreneurs are creators from scratch, aged 40 and over, and that this type of entrepreneurship is male-dominated. It should be noted that economic activities are segmented by field and by ethnic group, with the majority of players being Islamic. The location of the economic activity obeys various logics without forgetting that the experiential factor plays an important role in the choice of entrepreneurship as a professional career for Nigerian and Nigerian immigrants.

Objective: Immune plasma therapy, a method employed for passive immunization, has been utilized as a treatment modality based on historical precedents during the Covid-19 pandemic, a global crisis resulting in the unfortunate demise of countless individuals. The objective of this study is to investigate the impact of immune plasma therapy on laboratory parameters and the overall survival rate in patients with Covid-19 pneumonia.
Material and Methods: Our study was designed as a retrospective analysis, conducted at a tertiary healthcare institution from April 1, 2020, to December 31, 2020. The study population comprised individuals aged 18 and above, presenting with pulmonary involvement, and diagnosed with Covid-19 using the polymerase chain reaction (PCR) method at our hospital. The inclusion criteria encompassed patients who received immune plasma therapy, as well as a control group matched for age, gender, and admission date, who did not undergo immune plasma therapy. Exclusion criteria involved patients with low serum IgA levels, those who did not provide consent for immune plasma therapy, and individuals below the age of 18.
Results: The study comprised a total of 72 patients who received immune plasma therapy and 72 patients in the control group, matched for age and gender, all diagnosed with Covid-19. The median age of the patients was 70 years, ranging from 19 to 91, and 56.9% (41) of them were female. When comparing the immune plasma group with the control group, several significant differences were observed (p<0.05). These included elevated levels of leukocytes, neutrophils, neutrophil-lymphocyte ratio (NLR), glucose, aspartate aminotransferase (AST), sedimentation rate, C-reactive protein (CRP), ferritin, fibrinogen, d-dimer, and low levels of platelets and lymphocytes in the control group. Furthermore, in the immune plasma therapy group, significant associations were found between mortality and lymphocyte count, NLR, AST, CRP, and d-dimer elevation after treatment (p<0.05). Additionally, pre- and post-treatment measurements of troponin, procalcitonin, and ferritin were significantly correlated with mortality (p<0.05).
Conclusion: The administration of immune plasma therapy, involving the transfer of neutralizing antibodies, has demonstrated a favorable impact on laboratory parameters and overall survival in severe cases of Covid-19 pneumonia, particularly during the early stages of the disease.

Authors: Shalganov T. , Stoyanov M. , Traykov V.
Published: July 2023

This study presents data from the national electronic registry BG-EPHY on electrophysiologic (EP) cardiac ablations in 2022. Material and methods: This is a retrospective study of a full one-year sample of the BG-EPHY registry. Sex and age distribution of the patients, number of ablations, use of electroanatomic mapping (EAM), irrigated and cryoablations, distribution of different types of arrhythmias, acute procedural success and complications are presented. Results: In 2022 seven EP centers performed 1369 ablations in 872 men (63.7%) and 497 women (57% increase compared to previous year), incl. 15 ablations in pediatric patients (1.1%). EAM was used in 746 procedures (54.5%), irrigated-tip catheter – in 814 (59.5%), cryoballoon catheter – in 130 (9.5%), and intracardiac echocardiography – in 33 (2.4%). The most frequently performed ablation was pulmonary vein isolation (40.2%), followed by ablation for AV nodal reentrant tachycardia (18.6%) and typical atrial fl utter (16.6%). The acute success was over 98%, while intraprocedural complications were less than 2%. Conclusion: The national registry of electrophysiology collects systematically and continuously basic data on all ablations of cardiac arrhythmias performed in the country. In 2022, during a subsiding COVID-19 pandemic and with the inclusion of new centers the number of ablations increased compared to 2021. Distribution of EP procedure types was similar to previous years. Acute success was very high, while intraprocedural complications were rare.
A Critical Look at Ban-the-Box Policies and Their Unintended Consequences
Authors: Renfro Jayme Neiman
Published: July 2023

Ban-the-box policies were passed to help people with criminal backgrounds get jobs. These policies were developed after it became clear that large swaths of the population, primarily men of color, were being systematically disadvantaged and unable to obtain work. While initial research showed that these policies were successful, subsequent, more critical studies indicate that while ban-the-box policies help ex-felons obtain work generally, they may actually do more to hurt minority populations than they do to help. This happens because employers, lacking the information from “the box,” may be using other information, including statistical discrimination to determine who to hire. This chapter discusses this unintended consequence including its link with the race-neutrality of the policy and suggestions to fix it.

Published: July 2023

Univentricular dextrocardia is a rare complex congenital cyanotic heart disease. With the improvement of medical and surgical care, a greater number of women with complex congenital heart diseases have survived up to the childbearing age. Pregnancy with univentricular dextrocardia and Fontan circulation increases maternal and fetal mortality and morbidity. We report a case of successful management of two pregnancies in a woman with Fontan repaired dextrocardiac univentricular heart.

Published: July 2023

Lubricant additives are the main means to improve the performance of lubricants.
In this article, green and inexpensive layered kaolin were selected as lubricant
additives, and the effects of the type of modifier, concentration, particle size
of kaolin additives, and working temperatures on the tribological performance of
lubricants were investigated. The results showed that the Span80 modifier can
effectively improve the dispersibility and friction reduction effects of kaolin
oil samples. Compared with kaolin oil samples without the modifier, the modified
kaolin oil can reduce the friction coefficient by 40.9% and the wear spot
diameter of the steel balls by 43.8%. The layered kaolin additive can
significantly reduce the friction coefficient and wear of steel balls in
lubrication, and the friction coefficient showed a trend of decreasing and then
increasing with increasing kaolin additive concentration and particle size. The
optimal added concentration and particle size of kaolin are 5 wt% and 2 μm,
respectively, which can reduce the friction coefficient by 41.9% and 65.63% and
the wear spot diameter by 12.31% and 50.72%, respectively, compared with the
base oil. At five temperatures, compared with the base oil, the kaolin oil
samples all showed better friction reduction and anti-wear properties. The micro
and nano size of the kaolin additive, the layered structure, and the chemically
reactive film generated on the surface are the main reasons for its good
lubrication performance.
The application of the principle of precautions to cyber operations
Authors: Gül Yunus Emre
Published: July 2023

The interconnected nature of cyberspace hardens the application of the principle of precautions to cyber operations. Despite the fact that the principle of precautions falls behind the other two principles that regulate the conduct of hostilities (i.e., the principles of distinction and proportionality), its practical importance renders it as significant as those latter principles. However, in order to truly apply the principle of precautions in this complex environment, it should be applied by tilting it towards humanity rather than seeking to balance humanity with military necessity.
Autonomous systems, superior orders and manifest unlawfulness: is there a duty to disobey?
Authors: Walker-Munro Brendan
Published: July 2023

The recent development of the next generation of ‘drones’ featuring some form of artificial intelligence or machine learning – the autonomous military system or AMS – has fuelled speculation about who the law ought to hold responsible for any negligence or malfeasance in their use. In a scenario recently posted by the Australian War College, an Air Force pilot relies on sensor information and artificial intelligence assessments provided by AMS which led to an (ultimately unlawful) order to attack a target. If that story played out in real life, what disciplinary liability should that ADF member face for their actions: do AMS fundamentally challenge the circumstances in which Defence Force members should disobey unlawful orders? Would disciplinary liability be assigned differently if the pilot was from another host jurisdiction? This article comparatively examines the superior orders defence in the domestic law, with a view to identifying the application of the duty to disobey in relation to orders involving AMS.

Published: July 2023

Investigaciones previas han mostrado que la competencia docente mirar profesionalmente la enseñanza de las matemáticas se puede desarrollar en los programas de formación inicial a través de entornos de aprendizaje que permitan desarrollar las destrezas de reconocer e interpretar aspectos relevantes de la enseñanza de las matemáticas y decidir cómo continuar la enseñanza. Con el objetivo de identificar herramientas que ayuden a desarrollar esta competencia durante el período de prácticas, se solicitó a 19 estudiantes para maestro que escribieran narrativas sobre las situaciones de enseñanza de las matemáticas observadas durante este período. En estas narrativas tenían que describir una situación de enseñanza-aprendizaje donde se identificara que los estudiantes de primaria estaban desarrollando su competencia en Matemáticas, interpretarla (usando la teoría aprendida en las asignaturas de Didáctica de las Matemáticas), y proponer decisiones de enseñanza para favorecer el aprendizaje de los estudiantes. Tras la escritura de una primera narrativa los estudiantes para maestro la compartieron en un foro virtual donde podían recibir retroalimentación de sus compañeros y del tutor/a para, posteriormente, escribir una segunda narrativa. Los resultados de este estudio muestran que la escritura de narrativas y la retroalimentación en los foros virtuales favorecieron el desarrollo de esta competencia durante su período de prácticas.
