Staphylococcus aureus Induced Wound Infections Which Antimicrobial Resistance, Methicillin- and Vancomycin-Resistant: Assessment of Emergence and Cross Sectional Study.

Wound infection is a prevalent concern in the medical field, being is a multi-step process involving several biological processes. Methicillin-resistant S. aureus (MRSA) and vancomycin-resistant S. aureus (VRSA) infections often occur in areas of damaged skin, such as abrasions and open wounds. This research aims to light the incidence of MRSA and VRSA in wound swabs, the antimicrobial susceptibility configuration of isolated S. aureus patterns in pus/wound samples collected from Saudi Arabian tertiary hospital. The cross section study, β- lactamase detection, VRSA genotyping, MAR index, D-test and VRSA genotyping are methods, which used for completed this research. Patients of several ages and genders delivered specimens from two hospitals in the Al jouf area, in the northern province of Saudi Arabia. S. aureus was found in 188 (34.7%) of the 542 wounds. The traumatized wounds provided 71 isolates (38.8%), surgical wound provided 49 isolates (26.8%) and abscess were represented 16 by isolates (8.7%). In the study, 123 (65.4%) out of 188 were MRSA, 60 (31.9%) were MSSA, and five (2.7%) were VRSA. Linezolid and rifampin were found to be the most effective antimicrobials with 100% in vitro antibacterial activity against S. aureus isolates. The Multiple antimicrobials resistance (MAR) index revealed 73 isolates (38.9%) with a MAR index greater than 0.2, and 115 (61.1%) less than 0.2. The D-test showed that of MLSb phenotypes among S. aureus, 22 (11.7%) strains were D-test positive (MLSbi phenotype), 53 (28.2%) strains were constitutive MLSc phenotypes, and 17 (9%) strains were shown to have MSb phenotypes. All VRSA isolates (n=5) were found to be positive for vanA, and no vanB positive isolates were detected in the study. Regular monitoring and an antimicrobials stewardship program should be in place to provide critical information that can be utilized for empirical therapy and future prevention strategies.

Water security, participatory governance, and dialogue spaces for change in Northern Sri Lanka

AbstractWater Security through Participatory Action Research in the Northern Province (WASPAR) is a project driven by the University of Jaffna, Sri Lanka, since March 2020. The project itself and some of the significant outcomes over the 3‐year first phase of research are outlined here. WASPAR took inspiration from two emerging fields of study: Sociohydrology and Environmental Communication. Socio‐hydrology is envisaged as a science underpinning water governance, which engages with changes in both hydrology and society, not one or the other. Environmental Communication applied here works on the premise that how well we communicated with each other about water determined how well we addressed the ecological crisis. Communicating is synonymous to learning across multiple perspectives held by the many actors, often actors with competing interests and conflicting values. WASPAR acknowledged the limitations of existing institutional and social structures and their fragmented ways of water management. Instead, it put forward the search for a holistic, trans‐disciplinary, and multistakeholder approach for water security. Work to date on the project presented here reflect quantitative data gathered through empirical research within the project and in the field. Reflective analysis of qualitative data obtained from the participatory research processes are to be published later. Altogether, WASPAR project has made preliminary but promising steps in progressing towards informing, influencing and educating stakeholders, domain experts and decision‐makers on the need for and merits of participatory decision‐making, generating a sense of community, and the development of institutional infrastructure. Continuation of these efforts with increased participation of the research community in the universities during the next phase of this project needs to foster the governance approach and ensure the legitimacy and influence of the Northern Water Dialogue Forum in place for planning a water secure future for the Province.

With the rising trend of prostate cancer, where does northern Sri Lanka stand? A cohort study from a tertiary care centre.

Introduction: Prostate cancer is the second most common cancer among males all over the world in 2020. As per the global cancer observatory 1, 414, 259 (7.3%) cases were diagnosed in 2020 worldwide. The study aims to analyse the variations in demographic and clinico-pathological characteristics of prostate cancer in the Northern Province.
 Methods: This is a cross-sectional descriptive institution-based study that recruited all the prostate cancer patients who were treated at the Teaching hospital, Jaffna from August 2019 to August 2022. Data were extracted retrospectively from the clinic records of the patients as well as histopathology documents.
 Results: A total of 141 diagnosed patients at Teaching Hospital Jaffna were analysed. The mean age of the sample was 70.11± 8.43 years. Out of 141 patients, 30.49% were diagnosed to have localized disease and 26.24% and 43.26% with locally advanced and metastatic disease respectively. Out of those who had localized disease 68.5% were managed with radiotherapy, 23.25% with active surveillance and 11.6% with radical prostatectomy. The mean value of PSA was 70.11±8.4. The majority 97.2% had small acinar adeno carcinoma as histology. As per the D’Amico classification system for prostate cancer, 2.83% belonged to low-risk category and 80.1% belonged to high-risk category.
 Conclusion: There is a rising trend in the incidence of prostate cancer in Sri Lanka over the recent past. Most of the cases are advanced at the initial presentation. It implies the need for screening programmes with PSA in near future to detect cancer at early stages, implementation of cancer awareness programmes as practised in Western countries and strict adherence to national guidelines on management and referral pathways.

Analysis of the information ability of nurses in county hospitals in northern Henan province: a survey

ObjectiveTo investigate the status quo of nursing information ability of nurses in county-level hospitals and analyze its influencing factors.MethodsIn June 2022, a total of 303 on-the-job clinical nurses from 3 county-level hospitals in Hebi City, Henan Province were selected as subjects by convenience sampling method. General data questionnaire and self-rating nursing information ability scale were used to investigate them.ResultsThe total score of nursing information ability of 303 nurses in county hospitals of Hebi City, Henan Province was (77.72 ± 18.76). There were statistically significant differences in the scores of nursing information ability among different ages, working years, positions, education, marriage, monthly income, whether they had learned computer-related knowledge and skills, and whether they had participated in the learning or training of nursing information system (all p < 0.05).Multiple linear regression analysis showed that age, years, position, monthly income and whether they had learned computer-related knowledge and skills were the main influencing factors of nursing information ability of county-level nurses (all p < 0.05).ConclusionsThe nursing information ability of nurses in county-level hospitals in northern Henan is at a medium level. The government or society should provide training and guidance on nursing information ability, so as to provide more opportunities for nurses in county-level hospitals to participate in and learn nursing information technology to improve their ability.

Epidemiological survey of hypertension among middle-aged and elderly adults in Anhui Province.

To understand and analyze the prevalence and treatment of hypertension among residents aged 45 years and older in northern and southern Anhui Province to provide an opportunity to improve awareness, taking into account and standardizing hypertension management. Using a stratified cluster random sampling method, Anhui Province was divided into northern and southern Anhui regions using the Yangtze River as the boundary. The prevalence rate, awareness rate, treatment rate, control rate, related risk factors and complications of hypertension in the community population aged ≥ 45 years in Anhui Province were investigated using a questionnaire survey and a physical examination. The chi-square test was used to analyze the regional differences in hypertension prevalence, awareness, treatment and control rates. Weighted logistic regression was used to analyze the risk factors for hypertension. A total of 1331 residents aged ≥ 45 years were included. The results showed that the overall prevalence of hypertension in the Anhui Province population aged ≥ 45 years was 47.48% (50.73% in northern Anhui and 43.21% in southern Anhui), and the prevalence of hypertension in northern Anhui was higher than that in southern Anhui. The survey showed that the overall hypertension awareness rate in Anhui Province was 59.67%, the hypertension treatment rate was 44.46%, and the hypertension control rate was 30.70%. The differences between the 2 regions was statistically significant. The hypertension awareness, treatment and control rates in southern Anhui were higher than those in northern Anhui (P < .05). The risk factors for hypertension were older age, rural residence, male, obesity, low education level, high salt diet, smoking, excessive drinking, poor sleep, insufficient exercise, a family history of hypertension, a history of diabetes, and a history of hyperlipidemia. The most common complication of hypertension in middle-aged and elderly people in Anhui Province was cerebrovascular disease, followed by cardiovascular disease. Calcium channel blockers were the most commonly used antihypertensive drugs in middle-aged and elderly people in Anhui Province, followed by angiotensin converting enzyme inhibitor or angiotensin receptor blocker receptor antagonists.

Optimizing the structure of food production in China to improve the sustainability of water resources

The conflict between the growing demand for food and limited water resources is intensifying. To further elucidate the relationship between food and water, we construct a water footprint life cycle assessment framework for food products and propose a modified algorithm for measuring a food's water footprint to assess the virtual water transfer between grain crops and animal products. To address the mismatch between regional water resources and food production, we propose a novel optimization model for food production structure, with both reducing water use and maintaining food security as its objectives. Using 2020 as an example, the analysis proposes an adjusted food production structure for China at national, regional, and provincial scales. The results show that 24.9 % of water consumed by grain crops is transferred to animal products through feed grain. The total water footprint of food production in China is 820.8 billion m3, with the blue water footprint accounting for 32.9 % of that total. The blue water footprint for food production in northern China is 161.8 billion m3, which is much larger than 108.2 billion m3 in southern China. Water scarcity is also greater in northern regions, which produce the majority of grain and animal products. Our optimization shows that a reasonable food production structure can balance water resources and food security by remarkably reducing China's total blue water footprint and increasing food production in the south while reducing production in certain northern provinces to ensure sustainable regional development.

Evaluation of integrated waste management by using of Waste Reduction Model (WARM)- (Case study of Amol-Noor region, Iran)

Lack of proper municipal solid management in the Northern provinces of Iran has led to damages to the natural resources, health, environment, social and economic conditions. Construction of solid waste processing plants such as compost and incineration, ignoring essential elements in waste management, cannot be as a successful strategy to solve the solid waste problems. Integrated management as a suitable and well-proved solution in many developed countries was proposed for Mazandaran province as a more reliable strategy to replace the existing conditions. In this paper, the results of study conducted for Amol and Noor region have been analyzed. Minimizing waste production, maximizing recycling and reuse, processing organic waste through digestion or composting process, producing refusing derived fuel (RDF) and using it in the waste incineration plants or Neka cement plant and finally disposing less than 10% of the waste in landfill is the proposed solution to improve the existing waste conditions. Implementing the proposed integrated management over a period of 20 years will lead to preventing from economic and environmental damages due to the loss of valuable natural resources and the release of various pollutants from landfills which is evaluated to be equivalent of about 28 billion dollars also, saving resources and energy estimated to be about 38 billion dollars.

Genetic Variability and Molecular Evolution of Tomato Mosaic Virus Populations in Three Northern China Provinces.

RNA viruses tend to mutate during transmission and host infection, which is critical to viral adaptation and evolution. Tomato mosaic virus (ToMV) is a member of the genus Tobamovirus (family Virgaviridae) and an economically important virus with detrimental effects on tomatoes worldwide. Although the ToMV gene sequences have been completed in China, their genetic diversity and population structure remain unclear. We collected 425 tomato samples from tomato-growing areas in three northern Chinese provinces 2016. Reverse transcription PCR results showed that the average incidence of the virus in the field samples was 67.15%, and ToMV was detected in all test areas. The analysis of ToMV single nucleotide polymorphisms in China showed that ToMV was evolutionarily conserved, and the variation in the whole genome was uneven. Pairwise identity analysis showed significant variability in genome sequences among ToMV strains with genomic nucleotide identities of 73.2-99.6%. The ToMV population in the northern Chinese provinces had purification and selection functions, which were beneficial in the evolution of the ToMV population. Although there has been some distribution of ToMV strains in China, the virus was generally stabilized as a uniform strain under the pressure of purification selection. Our findings show how to monitor the prevalent strains of ToMV and their virulence in China and provide useful information for its prevention and control.

Continued Circulation of Highly Pathogenic H5 Influenza Viruses in Vietnamese Live Bird Markets in 2018-2021.

We isolated 77 highly pathogenic avian influenza viruses during routine surveillance in live poultry markets in northern provinces of Vietnam from 2018 to 2021. These viruses are of the H5N6 subtype and belong to HA clades 2.3.4.4g and 2.3.4.4h. Interestingly, we did not detect viruses of clade 2.3.4.4b, which in recent years have dominated in different parts of the world. The viruses isolated in this current study do not encode major determinants of mammalian adaptation (e.g., PB2-E627K or PB1-D701N) but possess amino acid substitutions that may affect viral receptor-binding, replication, or the responses to human antiviral factors. Several of the highly pathogenic H5N6 virus samples contained other influenza viruses, providing an opportunity for reassortment. Collectively, our study demonstrates that the highly pathogenic H5 viruses circulating in Vietnam in 2018-2021 were different from those in other parts of the world, and that the Vietnamese H5 viruses continue to evolve through mutations and reassortment.

Risk mapping for Taenia solium: Applying multicriteria decision analysis in Lao PDR.

Taenia solium is ranked the most significant global foodborne parasite and the leading cause of epilepsy in low and middle-income countries. Diagnostic challenges have hampered disease control efforts to date and WHO has called for the development of risk mapping tools to assist endemic countries. This study describes the application of multicriteria decision analysis to map the risk of T. solium in Lao PDR and acts as a case study for other endemic countries. Multicriteria decision analysis was completed using census data on relevant risk factors in Lao PDR. Factors were weighted using an analytical hierarchy process. Village risk scores were calculated using a weighted linear combination and categorised using the Fisher-Jenks algorithm into low, medium, and high risk. District risk scores and categories were calculated using the mean village risk score for a district. Sensitivity analysis was completed by doubling and halving risk factor weights, one at a time, and assessing the standard deviation of scores and categories across all scenarios. A total of 2017 (23.7%) villages were classified as high risk, with 3312 (39.0%) medium and 3170 (37.3%) low risk. This resulted in 21 (14.2%) high-risk districts, 83 (56.1%) medium and 44 (29.7%) low-risk districts. The risk maps highlight two areas of interest which are high risk and low variation. The first is the northern province of Phongsaly, which is consistent with literature and anecdotal reports. The second is the southern Salavan and Xekong provinces, which have yet to be investigated in detail. Multicriteria decision analysis has provided a simple, rapid, and flexible approach to mapping the risk of T. solium in Lao PDR. The nature of the method means that it can be completed in any endemic country with available and appropriate risk factor data.

Ethno-regional favoritism and the political economy of school test scores

The northern provinces of Burundi have suffered from subordination in the education system since independence. This paper shows that the post-war, northern-led regime has chosen a drastic way to reverse that subordination. The national test (Concours National) at the end of primary school is at the heart of the matter. Using the universe of individual test score data which can be used to construct a school-level panel and applying difference-in-differences analysis, the paper shows strong improvements in test scores in northern versus southern schools since the ruling party won an absolute majority in the 2010 elections. Right after, schools situated in very poor, rural areas in the north score as high as schools in non-poor areas of the capital. The paper finds that increased success rates, improved mean test scores and decreased standard deviations are explained by the % of votes at the municipality level obtained by the ruling party in the 2010 parliamentary elections. Controlling for school budget per capita does not change the results. The latter are interpreted in the political economy of education reform in Burundi and considered as a case of ethno-regional favoritism in Africa.

Water quality in Northern Province of Sri Lanka: A bibliometric analysis of publications 1960–2021

AbstractGroundwater contamination derived from human activities including farming is a serious problem threatening water security in the Northern Province (NP) of Sri Lanka. Gathering all existing research knowledge on the province's water resource base to create a digital repository is a key action in the 3‐year action research project on water security. Papers gathered in the repository showed that water quality, particularly salinity in groundwater and its contamination, was a prominent theme in research over the past two decades. Thus, the scope of this bibliometric study is restricted to published work on water quality pertaining to the North during 1969–2021. Publications listed in four electronic databases, namely, Scopus, PubMed, Web of Science, and Google Scholar yielded 118 scholarly publications. This paper provides an overview of the publication types and distribution, titles of journals and conferences, authorship, institutions, countries, themes, and keywords used. Final 20 years of study period saw a substantial growth in publication rate of water quality papers in the NP with journal articles and conference papers being the dominant types at 63% and 35%, respectively. Authors from 52 different institutions contributed to production of these publications, 93% of whom represented public sector institutions in Sri Lanka. University of Jaffna was in the lead position in numeric terms (n = 82), followed by the University of Peradeniya (n = 28). A significant 81% of the papers accounted for studies on water contamination, some indication of the degree of concern for this aspect among the research community. Around 65% of papers have been published in a wide range of international journals, some of which are less well established. This tendency has implications for the scientific output in terms of its quality, peer review process, and in turn also for usefulness of the work in the local context and in policy making.

Obstacles and Challenges in Implementing STEM Education in High Schools: A Case Study in the Northern Mountains of Vietnam

&lt;p style="text-align:justify"&gt;Science, technology, engineering, and mathematics (STEM) education has been successfully implemented in many countries around the world, including Vietnam. Admittedly, it appears that Vietnamese teachers are encountering several obstacles and challenges as they adopt STEM education in their classrooms. The purpose of this study was to use the Delphi method to figure out the obstacles and challenges that teachers in six northern mountainous provinces of Vietnam encounter when teaching STEM education. As per research findings, teachers confront 11 obstacles and challenges when integrating STEM education in their classrooms, including: Teacher competency, time consumption in lesson planning and guiding students to produce STEM products, teachers' beliefs regarding STEM education, inflexible programs, insufficient facilities, examination pressures, lack of timely rewards and encouragement for effective teachers, teachers’ self-funding teaching STEM, students’ competence, students’ cultural, economic and social background, and disagreements from student’s parents. These findings assist administrators and teachers in developing future strategies for successfully implementing STEM education in Vietnam.&lt;/p&gt;

Prevalence of Chronic Hepatitis B Virus Infection in Sierra Leone, 1997-2022: A Systematic Review and Meta-Analysis.

Hepatitis B virus (HBV) infection is a major public health problem in Sierra Leone, yet reliable estimates of cases are lacking. This study aimed to provide an estimate of the national prevalence of chronic HBV infection in the general population and select groups in Sierra Leone. We used the electronic databases PubMed/MEDLINE, Embase, Scopus, ScienceDirect, Web of Science, Google Scholar, and African Journals Online to systematically review articles reporting hepatitis B infection surface antigen seroprevalence estimates in Sierra Leone during 1997-2022. We estimated pooled HBV seroprevalence rates and assessed potential sources of heterogeneity. Of 546 publications screened, 22 studies with a total sample size of 107,186 people were included in the systematic review and meta-analysis. The pooled prevalence of chronic HBV infection was 13.0% (95% CI, 10.0-16.0) (I2 = 99%; Pheterogeneity < 0.01). During the study period, the HBV prevalence rates were as follows: 17.9% (95% CI, 6.7-39.8) before 2015, 13.3% (95% CI, 10.4-16.9) during 2015-2019, and 10.7% (95% CI, 7.5-14.9) during 2020-2022. The use of the 2020-2022 HBV prevalence estimates corresponded to 870,000 cases of chronic HBV infection (uncertainty interval, 610,000-1,213,000), or approximately one in nine people. The highest HBV seroprevalence estimates were among adolescents aged 10-17 years (17.0%; 95% CI, 8.8-30.5), Ebola survivors (36.8%; 95% CI, 26.2-48.8), people living with HIV (15.9%; 95% CI, 10.6-23.0), and those in the Northern Province (19.0%; 95% CI, 6.4-44.7) and Southern Province (19.7%; 95% CI, 10.9-32.8) regions. These findings may help inform national HBV program implementation in Sierra Leone.

Multi-scale estimation of poverty rate using night-time light imagery

Explicit poverty data are critical for policymaking and targeting humanitarian aid. Poverty rate is the most widely accepted definition of a poverty status. However, poverty rate data are commonly available at country-level. Here, we proposed an approach that estimates the poverty rate at different spatial scales with a consistent standard within a country. We first trained the model based on household survey data and publicly available remote sensing data to derive a wealth index map, and then we developed the relationship between the wealth index and the poverty rate at country-level. The relationship finally was applied to estimate the multi-spatial scale poverty rates in the study area. We made validation between the estimated and statistical province-level poverty rates using relative error and R-Square. A case study was carried out in Mozambique. The results showed that the proposed model has a good ability to estimate poverty rate with an overall accuracy of 85.21%, as well as an R-Square of 0.94. There was a huge gap within Mozambique, with the Northern Provinces holding high poverty rates and the Southern Provinces holding low poverty rates. The district-level poverty rate map might reflect the negative impact of climate disasters, as well as the positive influence of economic and trade exchange. Given that the data we use are publicly available, the proposed methodology can be applied to other countries to estimate poverty rates at various spatial scales.

Intestinal helminth infections and associated risk factors among adults in the Lao People’s Democratic Republic

BackgroundHelminthiases are highly endemic in Southeast Asia, including the Lao People's Democratic Republic (Lao PDR). This study aimed to assess the current intestinal helminth infections and the associated risk factors among adults across the Lao PDR.MethodsA cross-sectional survey was conducted in 165 villages across 17 provinces and the Vientiane Capital, Lao PDR. A multi-stage sampling method was employed to select the adult study participants (≥ 18 years). Data collection included (1) interview of the study participants, (2) physical measurements, and (3) a five gram of stool sample from each study participant was collected and preserved in 10% formalin solution for intestinal helminth detection using formalin-ether concentration technique (FECT). Descriptive analysis was used to describe the socio-demographic characteristics of study participants and the prevalence of intestinal helminth infections. Logistic regressions were applied to test the association between intestinal helminth infection and individual risk factors. A P-value below 0.05 was considered statistically significant.ResultsA total of 2800 study participants were enrolled. Their average age was 46.0 years; 57.8% were female. Overall, 30.9%, 8.6% and 1.5% of study participants were infected with one, two, or three different intestinal helminth species, respectively. Among the study participants 21.6% were infected with hookworm, 18.8% with Opisthorchis viverrini-like (Ov-like) infection, 4.8% with Strongyloides stercoralis, 2.3% with Ascaris lumbricoides, 1.5% with Trichuris trichiura, and 3.3% with Taenia spp. Ov-like infection was of high prevalence in the southern (28.8%) and central (21.3%) provinces, while hookworm (26.3%), A. lumbricoides (7.3%), T. trichiura (3.1%), and Taenia spp. (4.2%) were prevalent in the northern provinces. Risk analysis showed that men were more likely to be infected with hookworm [adjusted odds ratio (aOR) = 1.2, P = 0.019]. The Lao-Tai ethnic group had a 5.2-times (P < 0.001) higher chance of having Ov-like infection than the minorities. Possession of toilet facility at home was associated with reduced odds for Ov-like (aOR = 0.4, P < 0.001) and hookworm (aOR = 0.6, P < 0.001) infections.ConclusionsOur study provides a nationwide update of the intestinal helminth prevalence among adults in Lao PDR. To the best of our knowledge, this is the first Lao nationwide survey on intestinal helminth infections and risk factors in adults. It provides crucial information for national control programs for intestinal helminth infections in Lao PDR.Graphical abstract

Revision of the enigmatic South African Cryptolaryngini (Coleoptera, Curculionidae), with description of a new genus and twenty-two new species

The weevil genus Cryptolarynx Van Schalkwyk, 1966 is endemic to the Northern and Western Cape provinces of South Africa. The two previously known species of the genus, C. vitis (Marshall, 1957) and C. estriatus (Marshall, 1957), have an aberrant globular body and head shape, which has made it difficult to place the genus into the classification systems of the Curculionoidea. This paper presents the description of 21 new species of Cryptolarynx from South Africa (C. subglaber Haran sp. nov., C. squamulatus Haran sp. nov., C. muellerae Haran sp. nov., C. hirtulus Haran sp. nov., C. robustus Haran sp. nov., C. namaquanus Haran sp. nov., C. carinatus Haran sp. nov., C. variabilis Haran sp. nov., C. pyrophilus Haran sp. nov., C. pilipes Haran sp. nov., C. armatus Haran sp. nov., C. falciformis Haran sp. nov., C. oberprieleri Haran sp. nov., C. spinicornis Haran sp. nov., C. cederbergensis Haran sp. nov., C. homaroides Haran sp. nov., C. marshalli Haran sp. nov., C. endroedyi Haran sp. nov., C. oberlanderi Haran sp. nov., C. san Haran sp. nov., and C. luteipennis Haran sp. nov.) and of one new genus and species, Hadrocryptolarynx major Haran gen. et sp. nov., also from South Africa. A redescription of the genus Cryptolarynx is provided to incorporate the characters of the new species. The plant genus Oxalis (Oxalidaceae) is recorded as larval host for several species of Cryptolarynx and for Hadrocryptolarynx Haran gen. nov., as their larvae develop in the subterranean bulbs of members of the genus, and the egg, larva and pupa of C. variabilis are described. The characters of the Cryptolarynx larva confirm that Cryptolaryngini are an early-diverging group of Curculionidae, with a placement among taxa currently classified in the subfamily Brachycerinae sensu lato, and although their exact taxonomic position remains unresolved, some larval characters, and also pupal ones, suggest a close relationship between Cryptolaryngini and Stenopelmus Schoenherr. Potential use of species of Cryptolarynx in the biological control of weedy South African species of Oxalis is discussed.

VI. Freedom of Testation in the Revolutionary and Napoleonic Legislation

Summary Contrary to what one could have deduced from art. 2 and 17 of the Déclaration des droits de l’homme et du citoyen, where property had been elevated as a natural right, imprescriptible, inviolable, and sacred, and art. 537 and 544 of the Code civil, where the owners had been given the right to use in the most absolute way and dispose freely of their property, neither the Revolutionary nor the Napoleonic lawmakers thought of the right of disposing freely of one’s property upon death as self-evident. Although there had been a long tradition of testamentary succession in the South of France, the right to dispose freely of one’s properties by testament led to tensions as to its articulation with the pro-intestate customs of the Northern provinces – in 1789–1804 French private law(s) had indeed not yet been unified and the unification process had given rise to several rearguard arguments in favour of local idiosyncrasies –, but most importantly, it led to tensions as to its articulation with the institution of family, one of the pillars, along with property, of the new social order that had emerged from the ruins of the Ancien Régime: the bourgeois society.

“Oriental affairs secretary” Semyon Avramov

The article examines the missions of the Russian consul in Iran, Semyon Avramov, based on archival documents. The former serf came to Iran in 1717 as a translator of the Ambassador Artemy Volynsky. He proved himself a skilled diplomat, was appointed consul and for several years carried out the tasks of Peter I, his successors and the commander of the Russian troops in Iran, General V.Ya. Levashov. Avramov accompanied Persian envoys to Russia, obtained information about the resources and trade of the Caspian provinces of Iran, negotiated with the rulers of the country and for several years sought to ratify the St. Petersburg Treaty of 1723, according to which Iran ceded the northern provinces to Russia in exchange for military assistance.
