National Park Service beach nourishment guidance (second edition)
Authors: Hart Kate , Lejeune Jodi , Beavers Rebecca , Whitin Sam , Overcash Christopher , LaFrance Bartley Monique , Boltz Suzie
Published: May 2023

Sandy coastal areas (including coastal dunes, beaches, and submerged intertidal and nearshore areas) are naturally dynamic ecosystems. These areas experience accretion, erosion, dune and island migration, overwash, and other processes as sediments are transported by the wind, waves, tides, and currents. If these natural physical processes are disrupted, the beach ecosystem may transform, become unstable, or disappear completely over time. Human development of coastal areas, sea level rise, and increasing frequency and intensity of coastal storms are examples of coastal change that interfere with sediment transport and therefore threaten the stability of coastal ecosystems. Beach nourishment is a nature-based engineering strategy that artificially delivers sand (a size of sediment) to a coastal ecosystem to lessen the disruption of sediment supply. Generally, beach nourishment is intended to mitigate erosion, protect infrastructure and buildings, and/or to restore habitat. The National Park Service (NPS) has produced an updated guidance manual that provides a consistent approach to beach nourishment based on sound coastal science and engineering. The goal of this updated guidance is to provide information on this method to protect and preserve the beaches and associated resources of the National Park System.

Published: May 2023

Purpose: The aim of this study was to compare the effects of scapular stabilization exercise with and without cognitive functional therapy (CFT) on disability and scapular kinematics in people suffering from chronic neck pain. Methods: A total of 72 patients with chronic non-specific neck pain were randomized into scapular stabilization exercise alone, n = 24, combined (scapular stabilization exercise + CFT), n = 24, and a control group, n = 24. Scapular kinematic and disability were measured at baseline and after the intervention. Results: Statistically significant differences in neck pain and disability scale (NPAD) were found when the multimodal physiotherapy group including a cognitive functional approach was compared with stabilization exercises group at 6 weeks (effect size (95%CI) = –1.63 (–2.55, –.71); P = 0.019). Regarding the neck disability index (NDI), a significant between-group difference was observed at six-week (effect size (95%CI) = –2.69 (–3.80, –1.58); P = 0.007), with the superiority of effect in multimodal physiotherapy group. A significant between-group difference was observed in the scapular upward rotation and scapular osterior tilt at 30°, 60°, 90° and 120° of shoulder adduction. Conclusions: A group-based multimodal rehabilitation program including scapular stabilization exercise plus cognitive functional therapy was superior to group-based stabilization exercises alone for decreasing disability and, improving scapular kinematic in patients with chronic neck pain

Published: May 2023

In the presented study, a PGS prepolymer (pPGS) was synthesized utilizing polycondensation technique (equimolar sebacic acid:glycerol ratio, 130 °C, 24 h). Subsequently, the pPGS was thermally cross-linked in vacuum oven in 130 °C for 84 and 168 h. The cylindrical and dumbbell-shaped samples were subjected for physico-chemical and thorough mechanical analysis including tensile and compressive strength evaluation as well as dynamic mechanical thermal analysis (DMTA). The study allowed for the investigation of alteration of PGS properties during cross-linking and decay of elastomeric properties over prolonged cross-linking time. Moreover, a deconvolution in FTIR analysis allowed to glimpse into the hydrogen bonding structure of the materials which weakens during the cross-linking. The obtained results can be utilized during designing PGS-based bulk materials for biomedical application where bearing mechanical loads and tuned chemical character is of vital importance.

Pada penelitian ini Meisterstadt Batam merencanakan limpasan air hujan dari luar kawasan tidak akan masuk ke dalam kawasan, sehingga daerah tangkapan air yang direncanakan pada awalnya tetap seluas 4,7 Ha seperti perencanaan awal. Berdasarkan luas daerah tangkapan air, perencanaan drainase menggunakan debit banjir 5 tahun. Analisis curah hujan menggunakan data curah hujan selama 10 tahun terakhir, dari tahun 2009 - 2019 yang bersumber dari satu stasiun hujan yaitu Stasiun Meteorologi Hang Nadim. Ada 3 jenis metode yang biasa digunakan dalam menghitung curah hujan rata-rata untuk pembangunan infrastruktur drainase, yaitu menghitung rata-ra aljabar, poligon thiessen, dan isohyet. Untuk proyek Pollux Meisterstadt Batam menggunakan metode rata-rata aljabar karena metode ini menjumlahkan semua hasil tingkat curah hujan pada semua stasiun dan membaginya dengan jumlah stasiun yang ada, maka perhitungan curah hujan sangat berpengaruh pada perencanaan sistem drainase karena itu dapat menentukan kapasitas air maksimum dari drainase. Dari hasil penelitian yang telah dilakukan diperoleh debit curah hujan yang sesuai tata letak drainase adalah 0,01 m³ / detik. Berdasarkan hasil dari perhitungan dimensi saluran yang diperlukan untuk Q5 adalah B = 0,40 m, h = 0,20, A = 0,08 m², P = 0,80 m, R = 0,10 m, v = 0,48 m/detik. Maka, Q = 0,04 m³/s, dengan tinggi jagaan 0,20 m. Lalu koefisien pengaliran sebesar 0,70.

Authors: Aprilia Dinda , Decroli Eva , Kam Alexander , Putra Robby Satria
Published: May 2023

Background: Gestational diabetes mellitus (GDM) is defined as a condition of glucose intolerance that is found during pregnancy. In pregnant women, urinary tract infection (UTI) is one of the most common bacterial infections that can be found. The infection can be worsened by diabetes as it was shown that the risk of UTI in pregnant women with diabetes (27.6%) is higher than those without diabetes (3%-10.1%). This study aimed to present a case of gestational diabetes mellitus and urinary tract infection.

Case presentation: A pregnant woman aged 38 years old with a 15-16 weeks gestational age was admitted with gestational diabetes mellitus and urinary tract infection. The patient was treated with an intravenous insulin drip and antibiotic. The patient was discharged after there was a clinical improvement.

Conclusion: There are many risk factors that can contribute to the development of UTI in pregnant women, with one of those being inadequate glycemic control. The treatment of UTI in pregnant women with GDM is generally the same as in those without GDM.
Inconsistency in the Definition of Small Fishermen within the Indonesian Legal Framework: A Comparative Study of Legislation
Authors: Bima Muhammad Rinaldy
Published: May 2023

This study aims to examine and analyze the norm conflict regarding the definition of small fishermen in legislation at the same hierarchical level. This study uses normative legal research with the statute, conceptual, and comparative approaches. The collected legal material is then qualitatively analyzed to describe the problem and answer study purposes. The results show that there is a conflict of norms between Law Number 45 of 2009 with Law Number 7 of 2016 in defining small fishermen. Law Number 45 of 2009 refers to fishermen with a maximum vessel size of 5 GT, while Law Number 7 of 2016 refers to fishermen who use their own or others’ vessels with a maximum size of 10 GT. On the other hand, GT is a unit of measure agreed upon as the provisions of the Convention on the International Tonnage Measurement of 1969 in determining the vessel category. To eliminate norm conflict concerning the definition of small fishermen, the Government enacted the GR in Lieu of Law Number 2 of 2022. Fatally, GR in Lieu of Law Number 2 of 2022 raises ambiguity which shows the definition of small fishermen is increasingly unclear. Therefore, it is recommended that the House of Representatives initiate amendments to Law Number 7 of 2016 and GR in Lieu of Law Number 2 of 2022. These amendments must accommodate a more specific indicator regarding vessel size, aligned with the provisions in Law Number 45 of 2009. These steps are expected to create greater legal clarity and certainty for small fishermen and provide improved guidance for all stakeholders in the maritime and fisheries sector.

In the paper the formation of zinc orthosilicate polymorphic modifications, namely, β-Zn2SiO4 and -Zn2SiO4, has been investigated during the heat treatment of the intermediants precipitated via the interaction between hydrosilica gel which is derived from serpentine minerals (Mg(Fe))6[Si4O10](OH)8, sodium hydroxide NaOH and zinc chloride ZnCl2 in aqueous medium. It has been revealed that the crystallization of β-Zn2SiO4 and -Zn2SiO4 in the formed intermediates proceeds differently depending on the conditions of the initial reagents stirring performed in air at ambient pressure.

During long-term storage of wet fine zirconium metal powder under certain conditions the process of particles aggregation may start, which leads to powder transformation into a solid lumpy material, which significantly limits its application range. The purpose of this work was to establish the probable causes leading to the aggregation of zirconium powder particles during long-term storage, and to assess the possibility of transferring the lumpy material to its initial powdery state while preserving its basic physical and chemical properties. Particles aggregation most likely happens due to participation of zirconium atoms of the metal layers in formation of oxo-bridging bonds in acidic medium. Lumpy material formed in the process of storage of sodium-thermal zirconium metal powder (PZrN-A) was used as an example for testing the method of particles disaggregation by means of sodium hydroxide solution treatment, which makes it possible to transform the lumpy material into a stable powdery state typical for standard powder. The mechanism of alkaline treatment consists in the irreversible rupture of oxo-bridging bonds in the material, and the formation of hydroxyl groups on the surface of zirconium particles, which is accompanied by the destruction of aggregates and their disintegration into individual particles. Treatment with sodium hydroxide solution of different concentration demonstrates no significant changes in chemical composition of particles surface layers and makes it possible to maintain the main physical and chemical characteristics of zirconium powder. Samples of zirconium powder were studied by scanning electron microscopy, X-ray spectral microanalysis. The content of total and active zirconium, the value of the specific surface area of the powders was determined. Their sensitivity to friction and electric spark is evaluated.

The research results are presented of sorption extraction of cesium from alkaline high-level waste solutions stored in Mayak tanks using the resorcinol-formaldehyde resin RFS-i and modified nickel ferrocyanide-based inorganic sorbent Fersal. It is shown that the overall sorption performance of the Fersal exceeds that of the RFS-i. However, unlike the Fersal, the RFS-i remains stable during repeated cycles. A preliminary conclusion has been drawn on the prospects of use of both sorption materials for decontamination of Mayak real alkaline HLW.
