Published: June 2022

The current research aims to explore the effects of Body condition score (BCS) reduction on some reproductive factors such as re-pregnancy rate, number of inseminations per pregnancy, clinical endometritis, and ovarian activity in Holstein cows and also the effects of number of calving and its difficulty, on changes in the BCS. Data analysis with spss 21 software shows that with a further decrease in BCS first month after delivery, the percentage of non-pregnant cases in the herd and the number of cows with inactive ovaries increases significantly. The rate of endometritis significantly increases by increasing negative changes in BCS by 0.5 units or more. The number of inseminations necessary for creating pregnancy in two groups of decrease in BCS was different with a statistically significant difference. The odds ratios of developing clinical endometritis and also inactive ovaries in cows with BCS changes< 0.5 were significantly greater. In addition, odds ratios of pregnancy with finally 3 inseminations in cows with changes in BCS ≤ 0.5 were significantly different from cows with higher BCS changes. BCS changes of cows in second calving were not significantly different from cows in first calving, while the changes in calving 3 and 4 were significantly different. Easy parturition and parturition with some help was not different in BCS changes but dystocia but dystocia has been associated with significant BCs changes (P<0.05). According to these results, it can be concluded that a further reduction in BCS was associated with a reduction in the reproductive performance.

Authors: Matur Erdal , Keten Mehmet
Published: June 2022

This experiment was performed to investigate the effect of flaxseed oil and sunflower oil supplementation on the production performance, egg quality, and egg sensory characteristics in laying hens under density stress. A totaly of 144 Atak-S hens were used. The animals were assigned into 2 groups as stressed and unstressed. These were allocated into three subgroups as those who were fed with basal diet, diets containing 2% sunflower oil, and 2% flaxseed oil. Density stress was applied to those in the stress group by providing an area of 357 cm2 per hen. Egg production performance, average egg weight and egg mass, eggshell weight, eggshell thickness, eggshell strength, Haugh unit, albumen height, yolk color and sensory carateristics of the eggs were measured. Flaxseed oil reduced egg production and egg mass in those who are unstressed. On the contrary, it increased egg production and egg mass in the stressed groups. Sunflower oil was found to increase the average egg weight and egg mass in all groups. It was observed that when sunflower oil was added to the diets of the stressed chickens, the yolk color index decreased. In addition, it was determined that the eggs of the nostressed hens taste better than the stressed chickens. It was determined that flaxseed oil added to the diets increased the sensory quality of the eggs in both stressed and non-stressed groups. Therefore, incorporation of flaxseed and sunflower oil into the diets of layer hens can be recommended.

Published: June 2022

This study was carried out to determine the association between milk production characteristics at the start of lactation (the first three month of lactation) and the performance of reproduction within dairy cows of Algeria. Data were collected from Holstein cows (n=920) that calved between October 2017 and October 2019. Reproductive parameters included in the study were: calving to first-service interval (CFSI, days), calving to conception interval (CCI, days), services per conception (SPC), and conception rate at ﬁrst-service (CRFS %). Milk parameters such as peak milk yield, cumulative milk yield in the first 30 days (Milk30), 60 days (Milk60) and 100 days (Milk100) postpartum of the cows. The milk composition traits analyzed were milk fat concentration (MF %) and milk protein concentration (MP %). These variables were used to calculate fat to protein ratio (FPR) for each stage of lactation (stage 1: 15–30 days, stage 2: 45–60 days and stage 3: 75–90 days postpartum). Pearson’s correlation analysis was used to determine the correlation between reproductive parameters and milk production variables.The obtained results showed that peak milk yield, cumulative milk yield in the first 60 days (Milk60) and 100 days (Milk100) were significantly and positively (P<0.05) correlated with all the measured fertility parameters. Furthermore, fat to protein ratio (FPR) and milk fat content correlated significantly and negatively (P<0.05) with CFSI, CCI and SPC in the first two stages. The correlation between milk protein content with CFSI, CCI and SPC were negative and significant in the all three stages. Further research is required to identify the cause of this association.

Published: June 2022

Rheumatoid arthritis (RA) is a great concern across the globe. It is characterized as an autoimmune disease, where the body's immune system mistakenly attacks bone joints causing them to erode which leads to deformity in structure. Thus, the present study was conducted to elucidate the effect of Lidang Tang (LDT) decoction, a traditional Chinese medicine against rheumatoid arthritis. The rheumatoid arthritis was induced in Sprague-Dawley albino rats by intradermal injection of bovine collagen II type at the tail. Results suggested that LDT reduces paw swelling and arthritic scores in rats. The protective effect of LDT against RA was further substantiated by histopathological analysis of synovial tissue of rats, where LDT improves the architecture of the tissues as compared to CIA rats. It also reduces oxidative stress and inflammation in CIA rats as compared to the disease model group. The serum level of anti-collagen II-specific immunoglobulins (IgG1 and IgG2a) was reduced significantly in LDT treated group. In a western blot analysis, LDT treated group showed a significant reduction in the expression of NF-ĸB and COX-2 as compared to CIA rats. Collectively, our study for the first time demonstrated the protective effect of Lidang Tang decoction against rheumatoid arthritis.
Influence of lavender essential oil (Lavandula angustifolia) and oxytetracycline in nutrition of honey bees, prevention of American foulbrood and overall welfare
Authors: Puvača Nikola
Published: June 2022

Recently, there has been an increasing demand for natural, healthy, and safe products without residual antibiotics for human consumption, particularly bee products. Beekeepers have been struggling with this problem many years, having in mind often occurrence of American foulbrood, which is one of the most severe honey bee brood diseases, and till now have been successfully eradicated with heavy usage of antibiotics. Such controlled, or mostly uncontrolled usage of antibiotics in fighting against American foulbrood lead to a residual quantity of antibiotic in honey. To overcome this problem, this research aimed to investigate the influence of single essential oil (Lavandula angustifolia) compared to antibiotics in honey bee production on the prevention of American foulbrood. Totally three treatments were formed artificially infected with P. larvae spore suspension, at concentration 2×109 spore/ml. The course of the disease was regularly monitored. Treatment one (T1) did not receive antibiotic therapy. Treatment two (T2) was given lavender essential oil at a concentration of 0.1% of sugar syrup. The treatment was applied for 30 days, at 48h intervals. Treatment three (T3) received antibiotics in the sugar syrup at a concentration of 0.1%, respectively. Clinical and laboratory examinations were performed on days 10, 20, 40 and 60, respectively. Besides, L. angustifolia essential oil rich in Ethanol, 2-(2-ethoxyethoxy)- (13.05%), linalool (10.71%), α-Terpinyl acetate (10.93%) and linalool acetate (9.60%), showed its positive effects against antibiotics in combat of American foulbrood, further research with a specifically designed qualitative and quantitative mixture of essential oils are more than necessary because single essential oil is not enough and didn’t show expected results.

Authors: Kanbur Gülşah , Parlat Sinan Sefa
Published: June 2022

This study was designed to determine the effects of a single dose of dietary Cysteamine (Cys) on growth and laying performance, meat properties, hatchability, and plasma glucose, cholesterol, and sex hormone levels of quail in two experiments that followed each other. Trial 1 (T1): A total of two hundred, 1-d old quail (Coturnix coturnix japonica) chicks were randomly allocated to 1 of two treatment groups with 5 replicates, either a control group (basal diet) or a treatment group that contain 90 mg Cys per kg basal diet. During the 5 weeks growth period performance data regarding the growth period were collected. At the end of T1, a total of 30 quail were slaughtered, and color values, pH, and meat macronutrients were determined of breast meat. Data from T1 showed that the inclusion of 90 mg Cys in the diet did affect neither growth performance nor breast meat parameters of quail. Trial 2 (T2): At the end of T1, 40 from each treatment and a total of 80, six-weeks-old quail were selected randomly to use in the laying period experiment. Feeding with Cys added (90 mg/kg basal diet) and control (Basal) diets have been lasted in two treatment groups for 10 weeks for laying period. Laying and hatching performance data collected during T2, at the end of the trial, a total of 20 quails were sacrificed and plasma glucose, cholesterol, and sex hormone levels detected. Results of T2 displayed that 90 mg /kg feed dietary Cys increased egg mass (P< 0.05), however, it was ineffective on other laying and hatching performance parameters. Whereas plasma glucose level was not altered, plasma cholesterol level significantly decreased with the presence of Cys in the diet (P< 0.05). Moreover, dietary Cys significantly increased plasma sex hormones levels in both sexes. Concluded, 90 mg dietary Cys did not show an improving or depressing effect on the growth, laying, or hatching performance of quails however, its cholesterol-lowering impact and boosting effects on plasma sex hormones are noteworthy.

Published: June 2022

The present study evaluated supplementation of zinc from different sources during chicken semen cryopreservation on post-thaw semen quality and fertility. Adult White Leghorn chicken semen was cryopreserved using 4% dimethyl sulfoxide (DMSO) in Sasaki diluent (SD). In the semen cryomixture zinc oxide (6.25 and 12.5 µM) and zinc sulphate (100 and 200 µM) was added and cryopreserved. The plastic semen straws were thawed at 5°C for 100 sec and samples were evaluated for sperm motility, live, abnormal and acrosome intact sperm. The lipid peroxidation in the seminal plasma was evaluated. The semen cryopreservation and evaluation were repeated on six occasions. Fertility of the zinc supplemented semen was evaluated by inseminating into White Leghorn hens. Zinc supplementation did not affect any of the post-thaw sperm parameters. The lipid peroxidation and fertility were similar between the treatments.  In conclusion, supplementation of zinc as zinc oxide or zinc sulphate during chicken semen cryopreservation does not affect post-thaw semen parameters or fertility.

Published: June 2022

Background: Bionic hand prosthesis helps restore the original hand function. A survey on prosthetic users concluded that 79% thought that their devices were "too heavy". Therefore, the weight of the prosthesis is a major cause of user discomfort and fatigue. This research was aimed at the reduction of hand mass bionic prosthesis by optimizing the structure of the fingers with generative design methods. 

Methods: The materials used were Acrylonitrile butadiene styrene plastic and Nylon 6, and the manufacturing method used Additive Manufacturing. The prosthesis was designed with a lighter finger structure with a max displacement of 2 mm and a maximum safety factor of 4. 

Results: Generative design produced more than 80 designs. The selection of the best design was based on the status of design solutions, research limitations, visual aesthetics, recommendation values, and validation of mechanical performances.  The best is the SS-2. This design has an 80% lighter mass with the highest safety factor of 3.79, the lowest stress of 5.26 MPa, and the maximum displacement of 0.61 mm. 

Conclusion: Based on the exploration scheme, the generative design could produce more than 80 design solutions. The selection of the best design was based on the status of design solutions, research limitations, visual aesthetics, recommendation values, and validation of mechanical performances in the design. Design validation was carried out by simulating finite element analysis with static stress study methods in selected design candidates with input study cases similar to generative design exploration schemes. Finally, SS – 2 design was the best design produced by the generative design method with the highest factor of safety value of 3.79. Also gives an advantage to a stress value of at least 5.26 MPa in cases of segment loading, as well as the maximum displacement value of 0.61 mm.

The development of conceptual models of a digital city poses numerous challenges for developers. The public sector concept model has become one of the most difficult models to use. When developing algorithms to find a solution, the multidirectional interests of businesses and public institutions are combined. This type of model reflects the most acute and urgent problems faced by megapolises with regard to combining numerous localized services provided to the community in a limited territory. The administrations of both cities and regions (the scale of the smart territories) must make decisions concerning overcoming the barriers existing between the profits of commercial structures, the negative externalities generated by their activities, and the social benefits to the population in the territory under their control. It is necessary to solve this problem to achieve the effective management of enterprises belonging to the segment of long-term participants in various business activities, interacting with the surrounding social and business environment in a complex. This study takes into account the complex structures of the economic processes characteristic of megacities. The periodicity of economic processes is also taken into account. When choosing an optimization criterion, functions reflecting the level of internalization of responsibility for external effects were considered. The authors propose a mathematical model that can be used as part of the management decision support systems software, aiming at taking into account the externalities of a wide range of national, institutional, business, and social activities.

Background: The mitigation of unfair and avoidable differences in health is an increasing global priority. Observational studies including cohort, cross-sectional and case-control studies tend to report social determinants of health which could inform evidence syntheses on health equity and social justice. However, the extent of reporting and analysis of equity in equity-relevant observational studies is unknown.

Methods: We define studies which report outcomes for populations at risk of experiencing inequities as “equity-relevant”. Using a random sampling technique we will identify 320 equity-relevant observational studies published between 1 January 2020 to 27 April 2022 by searching the MEDLINE database. We will stratify sampling by 1) studies in high-income countries (HIC) and low- and middle-income countries (LMIC) according to the World Bank classification, 2) studies focused on COVID and those which are not, 3) studies focused on populations at risk of experiencing inequities and those on general populations that stratify their analyses. We will use the PROGRESS framework which stands for place of residence, race or ethnicity, occupation, gender or sex, religion, education, socioeconomic status, social capital, to identify dimensions where inequities may exist. Using a previously developed data extraction form we will pilot-test on eligible studies and revise as applicable.

Conclusions: The proposed methodological assessment of reporting will allow us to systematically understand the current reporting and analysis practices for health equity in observational studies. The findings of this study will help inform the development of the equity extension for the STROBE (Strengthening the Reporting of Observational studies in Epidemiology) reporting guidelines.

Published: June 2022

Background: In the last decade, there has been much interest in the area of solid polymer electrolyte (SPE) to address the issues of electrolyte leakage and evaporation in electrochromic devices (ECD). ECD is a state-of-the-art technology having the ability to change from transparent state to opaque state under the influence of a small applied voltage for energy saving applications.

Methods: In this work, tungsten oxide (WO3) films were fabricated via the sol-gel spin-coating method. Subsequently, ECDs were assembled based on SPE and liquid polymer electrolyte (LPE), respectively using indium doped tin oxide (ITO) coated glass as conducting electrodes and WO3 films as working electrode.

Results: Cyclic voltammetry (CV) results revealed reduced ionic conductivity of conducting ions in SPE based ECD (SECD) owing to increased viscosity by addition of PMMA. However, lesser time was required for the colouration process. LPE based ECD (LECD) showed higher colouration efficiency (CE) compared to its SECD counterpart. This is attributed to its larger optical modulation.

Conclusions: This work presents a comparison between the performance of LECD and SECD in terms of electrochromic (EC) and optical properties. They were analysed through CV, chronoamperometry (CA) and ultraviolet-visible (UV-Vis) spectrophotometer. Furthermore, this work provides an insight on the employment of solid-state electrolytes in ECDs in view of the persistent leakage and evaporation problems in ECD implementation.

Published: June 2022

Background: South African adolescents experience disproportionally high rates of violence, with lifelong health, social and economic impacts. Few papers present risk factors associated with experiences of adolescent violence.

Methods: A baseline cross-sectional survey was done (April 2017 – Sept 2018) with 3432 grade 8 learners in the Girls Achieve Power (GAP Year) trial from 26 high schools in three townships (Soweto and Tembisa, Gauteng and Khayelitsha, Western Cape). Collected data on lifetime experiences of different types of violence, perpetrators, and place of violence. Descriptive statistics and logistic regression were used to enumerate experiences of, and factors associated with violence.

Results: A total of 2383 respondents are included. Most (63.1%) were girls, 81.5% aged 12-14. In total 25.9% had ever experienced violence, higher among boys (p=<0.001). Physical violence was most common (35.7%), then psychological (21.8%), sexual (13.1%), neglect (10.6%), cyberbullying (7.6%), corporal punishment (6.5%) and economic abuse (4.8%). Boys experienced more physical violence (36.0%); girls experienced more psychological violence (22.2%). Gauteng had double the reports of sexual violence (18.4% vs 7.6%, p<0.001). Violence happened most at school (27.4%), followed by the park (19.8%) or their friends’ home (12.9%).

Multivariate analysis showed that boys (aOR 1.57; 95% CV 1.27-1.94; p=0.000), those aged 15-17 years (aOR 1.41; 95% CV 1.07-1.84; p=0.013), those who ever used substances (aOR 1.92; 95% CI 1.54-2.37; p=0.000), and those who sometimes feel worthless (aOR 1.35; 95% CI 1.10-1.64, p=0.003) were at higher odds of ever experiencing violence. Those who had never had sex were less likely to have ever experienced violence (aOR 0.66; 95% CI 0.51-0.83; p=0.001).

Conclusion: Urgently need wider adoption, scaling, and sustaining of evidence-based primary violence prevention and structural interventions are required to reduce the high burden of adolescent violence. Stakeholders across the ecological model are needed to tackle harmful cultural norms that perpetuate violence.

Published: June 2022

Background: Livestock are key sources of livelihood among pastoral communities. Livestock productivity is chiefly constrained by pests and diseases. Due to inadequate disease surveillance in northern Kenya, little is known about pathogens circulating within livestock and the role of livestock-associated biting keds (genus Hippobosca) in disease transmission. We aimed to identify the prevalence of selected hemopathogens in livestock and their associated blood-feeding keds.

Methods: We randomly collected 389 blood samples from goats (245), sheep (108), and donkeys (36), as well as 235 keds from both goats and sheep (116), donkeys (11), and dogs (108) in Laisamis, Marsabit County, northern Kenya. We screened all samples for selected hemopathogens by high-resolution melting (HRM) analysis and sequencing of PCR products amplified using primers specific to the genera: Anaplasma, Trypanosoma, Clostridium, Ehrlichia, Brucella, Theileria, and Babesia.

Results: In goats, we detected Anaplasma ovis (84.5%), a novel Anaplasma sp. (11.8%), Trypanosoma vivax (7.3%), Ehrlichia canis (66.1%), and Theileria ovis (0.8%). We also detected A. ovis (93.5%), E. canis (22.2%), and T. ovis (38.9%) in sheep. In donkeys, we detected ‘Candidatus Anaplasma camelii’ (11.1%), T. vivax (22.2%), E. canis (25%), and Theileria equi (13.9%). In addition, keds carried the following pathogens; goat/sheep keds - T. vivax (29.3%), Trypanosoma evansi (0.86%), Trypanosoma godfreyi (0.86%), and E. canis (51.7%); donkey keds - T. vivax (18.2%) and E. canis (63.6%); and dog keds - T. vivax (15.7%), T. evansi (0.9%), Trypanosoma simiae (0.9%), E. canis (76%), Clostridium perfringens (46.3%), Bartonella schoenbuchensis (76%), and Brucella abortus (5.6%).

Conclusions: We found that livestock and their associated ectoparasitic biting keds carry a number of infectious hemopathogens, including the zoonotic B. abortus. Dog keds harbored the most pathogens, suggesting dogs, which closely interact with livestock and humans, as key reservoirs of diseases in Laisamis. These findings can guide policy makers in disease control.

Zastosowanie Special Drawing Rights w omawianym obszarze uregulowań wpływa nie tylko na dochody budżetu państwa z tych kar, ale także może mieć znaczenie przy ustalaniu stopnia oddziaływania represyjnego na ukaranego i jego sytuację finansową. Wprowadzający charakter ma rozdział dotyczący miejsca administracyjnych kar pieniężnych w katalogu środków publicznych, jak i omówienie zakresu wykorzystania SDR w polskim prawie morskim. Umożliwiło to skoncentrowanie się w dalszej części artykułu na analizie szczegółowej art. 126 ustawy o bezpieczeństwie morskim oraz jego praktycznego zastosowania w latach 2014–2019. W ostatniej części przeanalizowano bowiem dane statystyczne, które uzyskano z Urzędu Morskiego w Gdyni i Urzędu Morskiego w Szczecinie.W opracowaniu zastosowano przede wszystkim dogmatycznoprawną oraz analityczną (statystyczną) metodę badawczą, przy czym ostatnią z metod ograniczono do lat 2014–2019, co podyktowane było sytuacją pandemiczną, która miała miejsce w 2020 r. i kolejnych latach. Stan epidemii oddziaływał na stan finansów publicznych Polski, a chcąc zachować porównywalność danych (w okresie relatywnie stabilnej sytuacji finansowej państwa), zawężenie ram czasowych uznano za potrzebne. Metody powyższe wykorzystano w odniesieniu do polskiego porządku prawnego, weryfikacji poglądów wyrażonych w literaturze przedmiotu (krajowej i zagranicznej) oraz przy omówieniu danych uzyskanych przez autora w trybie dostępu do informacji publicznej. W opracowaniu oparto się na stanie prawnym obowiązującym w dniu 28 marca 2022 r.
Samuel Bogumił Linde w Lipsku i Wiedniu. Wokół genezy Słownika języka polskiego
Authors: Dybaś Bogusław
Published: June 2022

Pochodzący z osiadłej w Toruniu szwedzkiej rodziny Samuel Bogumił Linde (1771-1847) jest znany przede wszystkim jako twórca sześciotomowego Słownika języka polskiego, opublikowanego po raz pierwszy w latach 1807-1814. Linde uczył się najpierw w Toruniu, następnie studiował od 1789 r.w Lipsku, szczególnie interesując się językoznawstwem, uzyskując z czasem stanowisko lektora języka polskiego na Uniwersytecie Lipskim. W czasie studiów, a także w efekcie kontaktów z polską emigracją polityczną po klęsce w wojnie polsko-rosyjskiej w 1792 r., zrodziła się idea opracowania słownika języka polskiego. W zasadniczej części została ona zrealizowana podczas dziewięcioletniej pracy w Wiedniu w charakterze bibliotekarza w prywatnej bibliotece Józefa Maksymiliana Ossolińskiego (późniejszej Bibliotece Ossolineum).

Dynamic Stochastic Matching Under Limited Time
Authors: Aouad Ali , Sarıtaç Ömer
Published: June 2022

In “Dynamic Stochastic Matching Under Limited Time,” Aouad and Sarıtaç analyze the design of matching policies in dynamic markets such as carpooling platforms and kidney exchange schemes. A crucial distinction with previous literature is that the agents’ arrivals and departures are fully dynamic. The demand and supply side are constantly replenished; each market participant remains available for potential matches during a limited period of time. Specifically, the authors formulate a general dynamic matching model over edge-weighted graphs, where the agents' arrivals and abandonments are stochastic and heterogeneous. The platform controls how long each agent waits and whom s/he is matched with. These decisions are subject to a fundamental tradeoff between increasing market thickness and mitigating the risk of abandonments from certain participants. The authors’ main contribution is to devise simple matching algorithms with strong performance guarantees for a broad class of networks. In contrast, they show that widely used batching algorithms have an arbitrary bad performance on certain graph-theoretic structures. Their analysis involves novel techniques including linear programming benchmarks, value function approximations, and proxies for continuous-time Markov chains, which may be of broader interest. Extensive simulations on real-world taxi demand data demonstrate that the newly developed algorithms can significantly improve cost efficiency against batching algorithms.
Primary school teachers’ awareness on STEAM learning: A starting point to develop STEAM-CB textbook

Published: June 2022

STEAM learning is an approach which integrates multidisciplinary knowledge while enriching students' skills to explore, try, ask, find, and build innovation, namely science, technology, engineering, art, and mathematics. We found that the learning resources of STEAM in Yogyakarta is very limited due to lack of knowledge about it. On the other hand, using local contexts as the starting point of learning is also important to foster character building.  This preliminary research aims to provide insight on the teachers’ awareness on STEAM learning and textbook, as well as the design we figured out after discussing it with the teachers. It was a descriptive qualitative research involving 214 primary school teachers. We collected the data through questionnaire and focus group discussion. The results suggest that STEAM is quite a new concept for most of primary school teachers in Yogyakarta. Not many teachers used to or have developed the STEAM learning resources, especially the one integrated with the character building. Therefore, a STEAM textbook needs to be developed to fulfill the need. Furthermore, the design of the textbook could have the characteristics of integrating all components of STEAM (science, technology, engineering, art, mathematics), starting from local context to develop characters, improving creative and critical thinking, having knowledge and skill assessment, and using project-based learning model.

Biopolitics, control and pandemic policing in Victoria, Australia
Authors: Ryan Emma , Warren Ian , Carlton Bree
Published: June 2022

The state of Victoria experienced the most far-reaching of Australia’s COVID-19 control strategies in 2020. While an initial lockdown resulted in a temporary abatement of reported infections, this was followed by an extensive resurgence of cases resulting in a 112-day lockdown from the end of winter through most of spring 2020. The ongoing social and economic costs of these measures are yet to be determined. However, our contribution proposes that the links between Foucauldian biopolitics and the Deleuzian society of control offer important insights into the impacts of the Victorian lockdowns on routine police work. Specifically, we argue that the evolution of pandemic policing, within a framework seeking to promote biopolitical control of Victoria’s population, unduly extended police powers and perpetuated many preexisting forms of bias and social injustice, which ultimately compromised public health.

In building on the work of Arrigo et al (2020), we document the theoretical relationships between biopolitics, control and the broad idea of pandemic policing. We suggest emerging forms of preemptive control are inextricably tied to a pre-crime securitisation logic that sought to curtail the spread of COVID-19 throughout both urban and regional communities in Victoria. We frame our discussion in light of the Victorian Ombudsman’s inquiry into Operation Benessere, which involved a sudden, hard lockdown in nine high-rise public housing estates in North-West Melbourne. Our analysis of this inquiry highlights the controversies of emergency pandemic enforcement and their implications for police organisational accountability. This case study reveals that biopolitical notions of control strengthened formal police powers under a state of emergency that targeted the urban poor, while immunising police from conventional forms of public accountability. We argue that these forms of biopolitical control associated with pandemic policing are characterised by the same sorts of selectivity, bias, and lack of formal accountability evident in many recent Victorian policing initiatives.

cladding, is proposed for spherical surface testing. The WG-SWS is used to overcome the drawbacks of the existing spherical wave sources, which can generate high accuracy and high numerical aperture spherical reference wave. In this paper, the theory of the WG-PDI is described, and the possible errors introduced by the device are analyzed. In addition, the lateral deviation between the curvature center of the test wave and the curvature center of the reference wave cannot be eliminated in the reflected configuration of the pinhole diffraction interferometer. After analyzing the influence of the systematic error introduced by the lateral deviation, the semi-reflective film was coated on the output facet of the waveguide spherical wave source to realize point diffraction interference without lateral deviation. Finally, the surface error of a spherical surface was measured by WG-PDI. The experimental results agree well with those measured by the ZYGO interferometer.
Flexible and wide-range tuning of liquid crystal polarization grating period based on single and interference-free exposure

Published: June 2022

We propose a period control method of liquid crystal polarization grating (LCPG) based on an nterference-free and single exposure process. By adjusting three parameters of exposure setup, including incident angle of exposure beam, wedge angle of birefringent prism and tilt angle of the sample, polarization distribution of the exposure beam is changed. The spatially variant polarization of the exposure beam is transferred to liquid crystal (LC) molecules by an azo-dye photo-sensitive layer. Consequently, the LCPG with the target period is obtained. The proposed method has high flexibility and a wide range of period adjustment covering several microns to more than thousands of microns according to calculated results. Experimental results fit well with calculations. The LCPGs with different values of period from 4.5µm to more than 200µm have been realized experimentally. The proposed interference-free method would accelerate the application of LCPGs with a robust and simple fabrication process.

Published: June 2022

We designed and optimized ultra-thin single junction InAlGaAs photonic power converters (PPC) with integrated back reflectors (BR) for operation at the telecommunications wavelength of 1310 nm and numerically studied the light trapping capability of three BR types: planar, cubic nano-textured, and pyramidal nano-textured. The PPC and BR geometries were optimized to absorb a fixed percentage of the incident light at the target wavelength by coupling finite difference time-domain (FDTD) calculations with a particle swarm optimization. With 90% absorptance, opto-electrical simulations revealed that ultra-thin PPCs with 5.6- to 8.4-fold thinner absorber layers can have open circuit voltages (Voc) that are 9-12% larger and power conversion efficiencies (PCE) that are 9-10% (relative) larger than conventional thick PPCs. Compared to a thick PPC with 98% absorptance, these ultra-thin designs reduce the absorber layer thickness by 9.5-14.2 times while improving theVocby 12-14% and resulting in a relative PCE enhancement of 3-4%. Of the studied BR designs, pyramidal BRs exhibit the highest performance for ultra-thin designs, reaching an efficiency of 43.2% with 90% absorptance, demonstrating the superior light trapping capability relative to planar and cubic nano-textured BRs.
