Published: March 2023

Abstract. The working fluid of a condensation particle counter (CPC) is one of its essential characteristics. Butanol is commonly used as the working fluid in alcohol-based CPCs due to its proven performance in various applications and a wide range of working conditions over the past almost five decades. At the same time, butanol has several disadvantages including its strong, unpleasant odour, negative effects when inhaled over prolonged periods, and flammability, making it troublesome to use in all places with strict safety regulations. We are proposing to address these negative issues by replacing it with dimethyl-sulfoxide (DMSO), a substance that has not been used as the working fluid in a CPC up to now. DMSO is an odourless, non-flammable, non-toxic substance that is easily accessible and inexpensive. During thorough experiments, this new substitute working fluid has proven to be stable in its performance in CPC and storage. We could show that DMSO behaves equivalent to butanol when used to operate a CPC in terms of the instrument's counting efficiency, D50 cut-off diameter and concentration linearity. In addition, we have demonstrated this for operating pressures ranging from ambient down to 200 hPa without the need for any safety precautions. Our new working fluid was tested on three CPC units representing two different models, almost always in side-by-side measurements. So far, we have achieved the best results with operating temperatures of 40 °C for the CPC’s saturator and 5 °C for its condenser. To address a less desirable property of DMSO, it could be mixed with a slight amount of water to decrease its freezing point significantly. When mixed accordingly, the substance stays liquid even in work environments with temperatures ≤ −10 °C and without any impact on the CPC's counting efficiency performance.

Abstract. This paper studies the impact of land use and land-cover change (LULCC) on the climate around 2 500 years ago (2.5 ka), a period of rapid transitions across the European landscape. One global climate model was used to force two regional climate models (RCMs). The RCMs used two land cover descriptions. The first was from a dynamical vegetation model representing potential land cover; the second a land cover description reconstructed from pollen data by statistical interpolation. The two different land covers enable us to study the impact of land cover on climate conditions. Since the difference in landscape openness between potential and reconstructed land cover is mostly due to LULCC, this can be taken as a measure of early anthropogenic effects on climate. The use of two RCMs enables us to study how sensitive climate models can be to land-cover changes. The results show that the simulated 2.5 ka climate was warmer than the simulated pre-industrial (PI) climate. The largest differences are seen in northern Europe, where the 2.5 ka climate is 2–4 °C warmer than PI. In summer, the difference between the simulated 2.5 ka and PI climates is smaller (0–3 °C), with the smallest differences in southern Europe. Differences in seasonal precipitation are mostly within ±10 %. In parts of northern Europe, the 2.5 ka climate is up to 30 % wetter in winter than that of PI. In summer there is a tendency for the 2.5 ka climate to be drier than PI in the Mediterranean region. The results also suggest that LULCC at 2.5 ka significantly impacted the climate in parts of Europe. Simulations including reconstructed LULCC (i.e. those using pollen-derived land cover descriptions) give up to 1 °C higher temperature in parts of northern Europe in winter and up to 1.5 °C warmer in southern Europe in summer than simulations with potential land cover. This relatively strong response implies that anthropogenic land cover changes that had occurred by the late prehistoric period may have already affected the European climate by 2.5 ka.

Published: March 2023

Abstract. We report a comprehensive data set characterizing and
quantifying the geometrically necessary dislocation (GND) density in the
crystallographic frame (ραc) and disclination density
(ρθ) in fine-grained polycrystalline olivine deformed in
uniaxial compression or torsion, at 1000 and 1200 ∘C, under a confining pressure of 300 MPa. Finite strains range from 0.11 up
to 8.6 %, and stresses reach up to 1073 MPa. The data set is a selection
of 19 electron backscatter diffraction maps acquired with conventional
angular resolution (0.5∘) but at high spatial resolution (step
size ranging between 0.05 and 0.1 µm). Thanks to analytical
improvement for data acquisition and treatment, notably with the use of ATEX (Analysis Tools for Electron and X-ray diffraction)
software, we report the spatial distribution of both GND and disclination
densities. Areas with the highest GND densities define sub-grain boundaries.
The type of GND densities involved also indicates that most olivine sub-grain
boundaries have a mixed character. Moreover, the strategy for visualization also
permits identifying minor GND that is not well organized as sub-grain boundaries
yet. A low-temperature and high-stress sample displays a higher but less organized GND density than in a sample deformed at high temperature for a similar
finite strain, grain size, and identical strain rate, confirming the action
of dislocation creep in these samples, even for micrometric grains (2 µm). Furthermore, disclination dipoles along grain boundaries are identified
in every undeformed and deformed electron backscatter diffraction (EBSD) map, mostly at the junction of a
grain boundary with a sub-grain but also along sub-grain boundaries and at
sub-grain boundary tips. Nevertheless, for the range of experimental
parameters investigated, there is no notable correlation of the disclination
density with stress, strain, or temperature. However, a broad positive
correlation between average disclination density and average GND density per
grain is found, confirming their similar role as defects producing
intragranular misorientation. Furthermore, a broad negative correlation
between the disclination density and the grain size or perimeter is found,
providing a first rule of thumb on the distribution of disclinations. Field
dislocation and disclination mechanics (FDDM) of the elastic fields due to
experimentally measured dislocations and disclinations (e.g., strains/rotations and stresses) provides further evidence of the interplay
between both types of defects. At last, our results also support that
disclinations act as a plastic deformation mechanism, by allowing rotation
of a very small crystal volume.
Decadal Growth in Emission Load of Major Air Pollutants in Delhi
Authors: Sahu Saroj Kumar , Mangaraj Poonam , Beig Gufran
Published: March 2023

Abstract. Indian capital megacity Delhi is reeling under deteriorating air quality and control measures are not yielding any significant changes mainly due to a poor understanding of sources of emissions, hence priority option in mitigation planning is lacking. In this paper, we have made an attempt to develop a spatially resolved technological high-resolution gridded (~0.4 km × 0.4 km) emission inventory for eight major pollutants of the Delhi region where high-resolution activity data of all possible major and unattended minor sources are generated by organizing a mega campaign involving 100s of volunteers. It is for the first time that we are able to estimate the decadal growth in emissions of various pollutants by comparing newly developed 2020 emissions with SAFAR emissions of 2010 using the identical methodology and quantum of activity data. The estimated annual emission for PM2.5, PM10, CO, NOx, VOC, SO2, BC and OC over Delhi-NCR are estimated to be 123.8 Gg/yr, 243.6 Gg/yr, 799.0 Gg/yr, 488.9 Gg/yr, 730.0 Gg/yr, 425.8 Gg/yr, 33.6 Gg/yr, and 20.3 Gg/yr respectively for the year 2020. The decadal growth (2010–2020) in PM2.5 and PM10 are found to be marginal 31 % and 3 % respectively. The maximum growth is found to be in the transport sector followed by the industrial and other sectors. Maximum decadal growth found for pollutants BC, OC and NOx is 57 %, 34 % and 91 % respectively. The decadal shift of sectorial emissions with changing policies is examined. The complete dataset is available on Zenodo at https://doi.org/10.5281/zenodo.7715595 (Sahu et al., 2023).
Mapping Antarctic Crevasses and their Evolution with Deep Learning Applied to Satellite Radar Imagery

Published: March 2023

Abstract. The fracturing of glaciers and ice shelves in Antarctica influences their dynamics, and may introduce as-yet poorly understood feedbacks and hysteresis into the ice sheet system. Therefore, data on the evolving distribution of crevasses is required to better understand the evolution of the ice sheet, though such data has traditionally been difficult and time consuming to generate. Here, we present an automated method of mapping crevasses on grounded and floating ice with the application of convolutional neural networks to Sentinel-1 synthetic aperture radar backscatter images acquired between 2015 and 2022. We apply this method across Antarctica to produce a 7-and-a-half year record of composite fracture maps at monthly intervals and 50 m spatial resolution, showing the distribution of crevasses around the majority of the ice sheet margin. We develop a method of quantifying changes to the density of ice shelf fractures using the timeseries of crevasse maps, and show increases in crevassing on the Thwaites and Pine Island ice shelves over the observational period, with observed changes elsewhere in the Amundsen Sea dominated by the advection of existing crevasses. Using stress fields computed using the BISICLES ice sheet model, we show that much of this structural change has occurred in strongly buttressing regions of these ice shelves, indicating a recent and ongoing link between fracturing and the developing dynamics of the Amundsen Sea Sector.
The Association of Blood Banks per City with Mortality Due to Traumatic Hemorrhagic Shock in Colombia: A Population-Based Analysis
Authors: Munoz-Valencia Alejandro , Bonilla-Escobar Francisco J. , Puyana Juan C.
Published: March 2023

Background: Hemorrhagic shock is the second leading cause of death for injured people and disproportionately affects low resource economies. The potential role of spatial allocation of blood banks and the unmet transfusion needs of patients are yet to be characterized. We aimed to estimate the effect of the number of blood banks in mortality due to traumatic hemorrhagic shock (THS) in Colombia.
Methods: We performed a population-based cross-sectional study using secondary data from the Colombian Government: including annual reports from the Blood Bank Network, mortality, and population estimates for 2015-2016. International Classification of Disease 10th code T79.4 identified THS as the primary cause of death. A city-clustered multivariate negative binomial regression, weighted by violent deaths rate, was used to obtain incidence rate ratios (IRR) of death due to THS with 95% confidence intervals (95%CI).
Results: Of the 59,030 violent deaths in Colombia in 2015-2016, 36.76% were due to THS. Only 3.13% of Colombian municipalities had a blood bank. THS incidence decreased as the number of blood banks in a city increased, and the lowest incidence was observed at ten banks (IRR:0.18, 95%CI:0.15-0.22). Receiving medical care in a city with blood banks had a more substantial impact on THS (IRR:0.85; 95%CI:0.76-0.96).
Conclusion: The number of blood banks per city was associated with lower incidence of THS deaths. These findings may highlight the inequitable distribution of blood systems and their association with preventable deaths. Further studies with more focused clinical and geographical data might clarify the geographic determinants of blood products’ availability.

Published: March 2023

Pembangkit Listrik Tenaga Uap (PLTU) merupakan pembangkit listrik yang menghasilkan energi panas dalam jumlah yang sangat besar. Oleh karena itu dalam sebuah pembangkit listrik harus memiliki alat yang berfungsi sebagai pendingin atau biasa disebut coolling system. Sistem pendingin dapat bersumber dari beberapa media, salah satu media yang biasa digunakan adalah air laut. Namun, penggunaan air laut secara terus menerus sebagai media colling system pada pembangkit listrik ini dapat memberikan dampak negatif apabila air keluaran sistem pendingin memiliki suhu panas melebihi ketentuan. Hal ini akan mengakibatkan terganggunya biota laut di sekitar pembuangan sistem colling keluaran air atau biasa disebut kanal hilir. Masalah ini sebenarnya sudah diantisipasi sejak awal berdirinya PLTU dengan membuat saluran kanal yang panjang dan berliku sehingga suhu sistem colling keluaran air bisa turun menyesuaikan suhu air laut, namun caranya tidak dilengkapi dengan alat untuk memantau suhu air di hilir kanal sebagai pembanding dengan sensor suhu di outlet kondensor. Dengan permasalahan ini, teknologi berbasis internet of things (IoT) dirancang
Laparoscopic selection for surgery in epithelial ovarian cancer. A short review
Authors: Ghirardi V , Fagotti A , Scambia G
Published: March 2023

The role of laparoscopy as a treatment selection method in ovarian cancer patients is receiving growing attention in surgical practice in both early and advanced-stage disease. When the disease is confined to the ovary, intraoperative laparoscopic assessment of the tumour features is needed to select the best surgical approach in order to prevent intraoperative spillage of cancer cells which would negatively impact patient prognosis. The role of laparoscopy as a disease distribution assessment tool in cases of advanced-stage disease is now accepted by current guidelines as an effective treatment strategy selection. Indeed, a published and validated laparoscopic scoring system, based on laparoscopic assessed intra-abdominal disease dissemination features have been demonstrated to be a reliable predictor of optimal cytoreduction achievement. This subsequently reduces the exploratory laparotomy rate in both primary and interval debulking surgery setting.

Furthermore, in cases of recurrent disease, the use of laparoscopy to predict whether complete tumour resection can be achieved is accepted by available guidelines. In this setting, the combination of laparoscopy and imaging techniques to manage platinum sensitive recurrent ovarian cancer cases showed a high accuracy in appropriately selected patients for secondary cytoreductive surgery.

In this article we describe the role of laparoscopy in the treatment selection-process in ovarian cancer patients.
The revival of vaginal surgery in the era of endoscopy: V-NOTES initial experience with a series of 32 patients
Authors: Raquet J , Namèche L , Nisolle M , Closon F
Published: March 2023

Background: Transvaginal natural orifice transluminal endoscopic surgery (V-NOTES) is an emerging surgical technique in the evolution of minimally invasive surgery. This technique allows different types of surgical procedures to be performed by vaginal access with endoscopic control. The combination of vaginal surgery and laparoscopy brings many advantages, especially the absence of incisions in the abdominal wall and better visualization of the abdominal cavity.

Objectives: In this retrospective study we report our initial experience of V-NOTES in benign gynaecologic surgery by describing our first consecutive 32 surgeries.

Materials and Methods: From June 2020 to January 2022, 32 gynaecological procedures were performed by V-NOTES by the same surgeon in a university hospital. Perioperative outcomes were evaluated retrospectively.

Main outcomes measures: Conversion to laparoscopy or laparotomy and peri-operative and post-operative complications.

Results: None of the 32 V-NOTES procedures required conversion to conventional laparoscopy or laparotomy. We observed 2 intraoperative complications managed by V-NOTES and 2 post-operative complications (Clavien-Dindo Grade 2).

Conclusion: Our results are similar to studies previously published about this subject and are promising concerning the techniques efficacy and safety. We do believe that a short training allows to reach benefits safely. However, further prospective multicentre randomized trials comparing V-NOTES to totally laparoscopic hysterectomy and to vaginal hysterectomy are needed to strengthen the validity of this new approach.

What’s new? V-NOTES widens the indications of vaginal hysterectomies by removing limitations such as large uterus, absence of prolapse, and history of caesarean. Moreover, this technique allows adnexal surgery to be performed by vaginal access.
Transformation of Coca to Cocaine: An Overview of Traditional Drug Use and Modern Drug Abuse
Authors: Toyne Marla
Published: March 2023

This research paper briefly reviews the complex relationship between traditional use of coca and the consumption of the recreational drug, cocaine. A review of the history of coca production and utilization in the Andean region of South American illustrates the bio-social evolution of this plant. Coca leaves also have long played a significant role in the local economy and ritual practice. Alternatively, cocaine’s history and modern position as an illegal narcotic has a different impact on individuals, society, and the global economy. This paper reviews the role that both “drugs” play in terms of the health and lifestyle effects on the respective consumers.
Multiple Histories: The Archaeology, Ethnohistory, Oral History, and National History of Iximche', Guatemala
Authors: Metcalfe Jessica
Published: March 2023

This article calls for the use of multiple histories to reconstruct the past. More specifically, it argues that Indigenous histories should figure prominently in archaeological discourse. Although the word ‘decolonization’ and its derivatives are never used in the article, it argues for what would today be recognized as a decolonizing approach: foregrounding Indigenous voices, conducting research with benefits for Indigenous communities, changing language that legitimizes Eurocentric views, and ‘braiding’ different ways of knowing about the past. Drawing on ethnohistoric sources, Maya oral histories, archaeological reports, and national histories told by Ladino authorities, this paper examines several historical themes in relation to the Maya site of Iximche’: its origins, conflict and ethnic relations, politics, religion, and identity. This case study shows that combining multiple historical perspectives has the potential to highlight the dynamic, changing, and sometimes contradictory histories of Iximche’s people, and to assert the relevance of Iximche’ and the Maya to Guatemala’s past, present, and future. More generally, bringing together ‘multiple histories’ is a way for archaeologists to build respectful partnerships with Indigenous peoples and act as allies in revitalizing Indigenous identities and cultures.

This article, deals the momentum of the country's forest reserve area, the distribution of forest reserve lands, the dynamics of forest reserve lands by regions and the percentage share of forestry institutions by territory. The current period of economic development is characterized by the escalation of the environmental crisis, the creation of new post-industrial civilization bases, the concept of sustainable development, the change of socio-economic relations in the direction of the creation of various property forms and their implementation, and the strengthening of integration processes. International agreements have declared the need for the world community to move towards sustainable development. The purpose of the sustainable development strategy is to effectively solve the social and economic tasks of the current and future generations, as well as the preservation of natural resource potential. Forest is an important strategic resource of Kazakhstan. It plays a big role in human life. As the main component of the regulation of the natural environment and its processes, the forest ensures the vital activity of humanity, and it also occupies a special place in the socio-economic development of society. Observance of the principle of continuous use of forests in a non-depleting manner by all participants in forest relations is considered the basis for preserving and increasing the ecological and resource potential of forests. Also, reproduction of renewable forest resources is the use of resources in such a way as to maintain the stability of the forest as an ecological system

На фоне быстро развивающихся и внедряющихся в практику сельского хозяйства цифровых технологий, начиная от координатного отбора почвенных образцов и заканчивая составлением, на этой основе, конкретных карт заданий для дифференцированного внесения удобрений, существующие группировки почв не в полной мере обеспечивают информативность пространственной вариабельности обследуемых территорий. А некоторые ее составляющие требуют определенной корректировки. Для условий юга и юго-востока Казахстана предложены эффективные уровни обеспеченности почв гумусом и подвижным фосфором, позволяющие повысить точность установления фактической пространственной вариабельности их содержания, исключить непродуктивное применение удобрений на основе диференцированного внесения туков. Еще одной очень важной проблемой для условий юга и юго-востока Казахстана является отсутствие результативных методов определения соединений азота в почве для установления потребности растений в азотных удобрениях. Содержание азота нитратов, которое очень часто используется для этих целей, не дает желаемых результатов в виду их высокой подвижности. Так как изменяется под воздействием температуры, аэрации, влажности и т.д. и актуально только на момент отбора почвенного образца и не позволяют судить о количестве доступного азота в почве в течение вегетационного периода. Кроме того, большая продолжительность периода положительных температур в годовом цикле еще больше усложняет диагностирование обеспеченности растений почвенным азотом. Для установления потребности полевых культур в азотных удобрениях, предлагается использовать показатели содержание щелочно-гидролизуемого азота в почве. Азотные удобрения должны применяются из расчета бездефицитного баланса на фоне учета структуры используемой пашни

The article presents data on the effect of soil mixtures on tomato seedlings of two varieties: «Novichok» and «Velmozha», since the right choice of components in the composition of soil mixtures will depend on obtaining healthy, properly formed tomato seedlings. Field soil with addition of peat, biohumus and horse mulch in different ratios was used as the main component in all the variants. According to the data obtained, the greatest biometric indicators tomato seedlings of the two varieties form in the variants with field soil and biohumus (1:1), field soil and horse mulch (2:1). These soils contribute to better growth and development of seedlings, the formation of its more ramified powerful root system, which provides the most favorable conditions for nutrient, water and air conditions, the photosynthetic activity of plants when transplanted into the open field, leading to an increase in productivity by 1,3–2,2 times, depending on the variety. In the variant with peat the tomato seedlings were stunted (4,6–4,9 cm) with a weak root system (1,6–2,2 cm); they were not transplanted to the open ground.

В данной статье представлены результаты селекционных исследований по зернобобовым культурам в ТОО «НПЦЗХ им. А.И. Бараева» за 2020-2021 годы. Целью наших исследований было сортоиспытание трех сортов чечевицы и трех гороха селекции ТОО «НПЦЗХ им. А.И. Бараева», выявление лучших сортов для возделывания в стрессовых погодных условиях Акмолинской области. Подготовка поля и закладка полевых опытов проводилась по рекомендациям ТОО «НПЦЗХ им. А.И. Бараева», по чистому пару. Оценка и результаты испытаний в условиях 2020-2021 гг свидетельствуют, что сравнительно высокой засухоустойчивостью и урожайностью обладают сорта гороха с усатым типом листа и сорта крупносеменной тарелочной чечевицы. Как видно из наблюдений 2020-2021 гг. отличались незначительными осадками, но их распределение по фазам развития растений сортов чечевицы и гороха ТОО «НПЦЗХ им. А.И. Бараева» были различными, температурный режим также отличался, в связи с чем урожайность 2021 г. по сравнению с урожайностью 2020 г. была выше. В период посева запаса влаги в почве было достаточно, но май был сухой и жаркий, испарение было максимальное, осадки в мае отсутствовали - именно с этим связано и уменьшение полевой всхожести в 2020 году, и уменьшение крупности полученных семян у гороха и чечевицы. Исходя из полученных данных за изучаемый период 2020-2021 наибольшей технологичностью, а именно: устойчивостью к полеганию, высотой растения и высотой прикрепления нижнего боба обладали: сорт гороха – КАСИБ и сорт чечевицы – Шырайлы.

В Республике Казахстан имеются огромные заросли водно-болотных растений. Наибольшую ценность представляет тростник южный.Тростник – самый урожайный из всех кормовых и промышленных растений Кызылординской области. Это позволяет использовать его заросли как сырьевую базу целлюлозно-бумажной промышленности и кормовую базу животноводства.Продуктивность и урожайность естественных тростниковых лугов и в Кызылординской области снижается с каждым годом. Причиной этого является неправильный уход за ними и использование, что приводит к уменьшению основного кормового растения - тростника - засорению участка вейником (Calamagrostis epigeios), солянками (Salsola crassa, S. sp.), шведками (Suaeda altissima, S. microphylla), ядовитыми растениями – гармалой (Peganum harmala), парнолистником (Zygophellum fabago, Gobelia alopecuroides) и различными сорными.

Published: March 2023

Purpose: To investigate the effect of detrusor overactivity (DO) on the urethral expression of caveolin (CAV)-1, -2, and -3 of urethra in an animal model of cyclophosphamide (CYP)-induced cystitis rat.Methods: Female Sprague-Dawley rats were divided into the control group (n=20) and the cystitis group (n=20). Cystitis was induced by intraperitoneal injection of CYP (200 mg/kg). An urodynamic study was done 3 days after the CYP injection to measure functional change of the urinary bladder and urethra. Cellular localization and expression of CAV-1, -2, and -3 in the rat urethra were determined by immunohistochemistry (IHC) and Western blot.Results: Urodynamic experiments demonstrated a decreased contraction interval in the cystitis group compared to the control (3.9±1.0 minutes vs. 6.6±1.2 minutes, P<0.05). Conversely, contraction pressure increased significantly in the cystitis group compared to the control (22.4±0.7 mmHg vs. 11.5±0.4 mmHg, P<0.05). The urethral pressure was decreased in the cystitis group compared to the control (4.05 ±2.5 mmHg vs. 5.8 ±2.8 mmHg, P <0.05). The IHC and Western blot data showed that CAV-1, -2, and -3 expression decreased significantly in the cystitis group compared control group (P<0.05).Conclusions: The decreased urethral CAV-1, -2, and -3 in the DO rats suggests that CAVs might be related with the functional change of urethra in association with DO of urinay bladder.

Aspal Buton (Asbuton) adalah  aspal  alam  yang  terkandung  dalam  deposit  batuan  yang  terdapat di pulau Buton dan sekitarnya. Dengan jumlah deposit Asbuton yang mencapai 650 juta ton, menjadikan Indonesia sebagai negara penghasil aspal alam terbesar di dunia. Kadar aspal yang  terkandung  dalam  Asbuton bervariasi, antara 10-40%. Ini merupakan kadar aspal  yang  cukup  besar  dibandingkan  dengan  kadar aspal alam negara-negara  lain  seperti  Amerika (12-15%)  dan  Prancis (6-10%).  Aspal Buton  merupakan satu-satunya aspal di Indonesia yang terbaik dan terbesar di dunia. Sejak 2015, pemerintah RI juga mengarahkan untuk mengoptimalkan penggunaan aspal Buton untuk pembangunan jalan. Adapun tujuan dilakukannya Kajian struktur biaya produksi aspal buton untuk kebutuhan insfrastruktur sebagai substitusi impor adalah tersedianya data dan informasi potensi bahan baku dan bahan penolong industri aspal buton dan tersedianya data industri bahan galian non logam untuk industri aspal buton. Tantangan terbesar pertama adalah bagaimana mengedukasi pelaku bisnis konstruksi jalan dalam menyerap dan mengimplementasikan teknologi dan konstruksi aspal Buton dengan cepat. Kedua, mendorong pembangunan pabrik aspal Buton di daerah-daerah terdekat dengan bahan baku untuk menekan biaya transportasi sehingga harga jual aspal Buton bisa bersaing di pasaran. Ketiga, melakukan upaya-upaya lainnya untuk memperkenalkan aspal buton kepada masyarakat. Pada 2018 penggunaan asbuton dilakukan pada jalan sepanjang 709 kilometer (km) yang tersebar pada ruas jalan di berbagai provinsi. Jumlah asbuton yang dibutuhkan sebesar 58.879 ton. Dari perhitungan merujuk pada kekuatan hotmix yg dinilai dg parameter Marshall Stability (MS) dari segi kualitas umur jalan, apabila memakai hotmix, aspal minyak, aspal buton hasilnya adalah MS hotmix dg aspal minyak 800 kg sedangkan MS hotmix dg aspal buton 1000 kg. Dengan metoda analisa komponen, bisa ditetapkan nilai Structural Number dari setiap tipe tsb, yg merujuk pada ketebalan lapisan dan/atau umur konstruksi. Makin besar MS, makin tipis atau makin panjang umur.

Published: March 2023

Urinary tract infections (UTI) constitute the most common morbidity during pregnancy resulting in severe complications and fatality. This study aimed to determine the prevalence and antibiotic susceptibility pattern of urinary tract infection among pregnant women attending Antenatal Care Clinic (ANC), at Dambam, Bauchi State. A total of 290 pregnant women aged 15 – 40 years (Mean age, 23.4 SD± 2.1 years) were screened for bacteriuria using standard microbiological method. Antimicrobial sensitivity pattern of the bacterial isolates was determined by Modified Kirby-Bauer disc diffusion method. Questionnaires were used to obtain information on biodata and socio-demographic characteristics of the study population. The prevalence of urinary tract infection among pregnant women screened was 17.24% (n = 50). Pseudomonas aeruginosa constitutes the most prevalent organism, 15 (5.17%) cultured, followed by Klebsiella spp 12, (4.14%) while Staphylococcus aureus, Staphylococcus saprophyticus and Enterococcus spp constitute the least isolates (1.38%) each. The study revealed a significant association (P_ < 0.05, P = 0.000) between the frequency of bacterial isolates and marital status while other demographic characteristics such as educational status, age and occupation of the subjects did not indicate any significant relationship. Majority of the bacterial isolates were resistant to Cefalexin, Levofloxacin, and Clindamycin but were however, sensitive to Ciprofloxacin, Ceftriaxone and Amoxicillin-clavulanic acid. Considering the significant bacterial isolates from pregnant women investigated expressing some resistance against commonly used antibiotics, hence there is need for educational campaign to enlighten women about UTIs during pregnancy and useful prevention/control measures to checkmate associated complications and fatality.

Analysis of large-scale droughts in the energy field by using mathematical programming: The case of the Paraná River basin
Authors: Alvarez Gonzalo E.
Published: March 2023

Effects of climate change can already be observed in many regions of the world. The basin of the Paraná River, in South America, has been suffering an important drought since 2019 in the whole region. The extension of the crisis has increased the risks in the flora and fauna, losses in logistics of navigation, besides the problems of urban water cleansing. In this regard, the novel proposal presents a new mathematical model to study the impact of this crisis. Besides the traditional constraints of the literature for hydraulic systems, this paper enhances inventory constraints, connections with electric systems, and other considerations as the head effects in electricity generation. Because several equations related to electricity generation are nonlinear (which the subsequent computational effort impacts), this proposal applies linearization techniques to reduce CPU times. The core is related to hydropower production, and the consequences of the water crisis in the regional markets. The mathematical model analyzes the interrelationships between reservoirs and water flows of the basin. To study the effectiveness of the novel proposal, the reported situation of the basin of the Paraná River is studied by considering two scenarios (normal conditions of the river flow and the conditions related to the drought). Results show that the crisis implies daily net economic losses of about 7 million USD for the operators of the power plants. Other problems (different from the ones related to the energy field) are also mentioned and analyzed.
