It is necessary to know various basic agronomic information about sorghum, especially the growth and yield of ratoon so that a sustainable and profitable crop cultivation package can be prepared. This research aimed to assess the vegetative and generative potentital of the Bioguma 1 sorghum variety as ratoon. This research was conducted at the research garden, Faculty of Agriculture, Universitas Sriwijaya, Indralaya from February 2023 until August 2023. The methodology used was non-experimental.  Sampling was carried out randomly for 80 plants from a population of 1600 plants. The research results showed that there was a decrease in vegetative and generative growth of ratoon sorghum compared to its parent. Decreases occurred in stem length (21%), number of leaves (50%), shoot dry weight (59%), panicle weight (61%), and number of seeds (22%). The decrease in generative components was greater than vegetative in ratoon sorghum plants

Halimi, E.S., Zaidan, Z., Susilawati, S., Adriansyah, F., Cahyani, A.I., Panjaitan, M.S., Agustina, P., & Nuraini, H. (2023). Growth yield and segregation of several f3 generation of pepper accessions selected from the cross of curly and cayenne peppers. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang  21 Oktober 2023. (pp. 358-369). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Suboptimal land, in general,  refers to condition of the land not prefectly suitable for cultivation, including those containing propagul caused disease infestation. On pepper cultivation, very often occurs disease infestation such as antracnose desease. Crossing curly and cayenne peppers was intended to obtain accessions of curly pepper having fruit position upward such as in cayenne pepper that capable of avoiding  several diseases infestation.  The F3-seeds were  prepared 3 years prior to this research with selection to choose plant genotypes having fruit position upward. Research was done in-cooperation with farmer at Kecamatan Gunung Megang, Muaraenim on December 2022 to May 2023 based on Randomized Block Design with  two accessions and three blocks with 10-15 plants per plot. Research  indicated that both accessions showed good growth and yield with relatively similar harvesting period and yield potential. Interestingly, we observed several recombinat plants having fruit shape identical to curly peppers with fruit position upward.  The plants of CK3(2)xCR3(6) accession, however had more slender fruit shape as compared to CK6(8)xCR6(4) accession. Furthermore observation indicated the presence of segregation of this character. Accession of CK3(2)xCR3(6) showed higher segregation value of 50% than CK6(8)xCR6(4) accession  with segregation value of  25%

Seawater desalination transforming the Gaza Strip

There are no easy conventional solution to Gaza’s chronic water crisis and impending environmental catastrophe. Seawater desalination is one of the key transformative interventions strategically considered to address both these issues. UNICEF, with European Union funding, therefore initiated the implementation of a seawater desalination programme in late 2012. The first phase of the seawater desalination plant producing 6,000 m3/d, is the largest to be completed in Gaza and is to be extended to produce 20,000 m3/d to ultimately serve a population of 250,000 people. Seawater desalination remaining an energy intensive process, focus has been on identifying innovative means of generating and conserving energy to tackle the energy-water nexus, given the limited availability of electricity within Gaza. Advance renewable energy and energy recovery technologies have been incorporated to maximise the plant’s viability. Such transformative technologies is essential to ensure that Gaza remains a liveable place in the years to come

Эффективность in vitro инактивации бактерий Bacillus subtilis и Escherichia coli в стерилизаторах с использованием облучения в фиолетовой области

Bacteria are inactivated using a technique called photodynamic inactivation, which combines light with a photosensitizer with the right spectrum. The objective of this study is to ascertain the e­ciency of purple LEDs for photoinactivating Bacillus subtilis and Escherichia coli bacteria as well as the ideal purple LED exposure energy density. This study technique involves exposing bacteria to purple LED radiation. Two elements of variation are used during irradiation. The first variation is the illumination variation at distances of 3 cm, 6 cm, 9 cm, and 12 cm. The second variation involves changing the amount of radiation for 30, 60, 90, and 120 minutes. The Total Plate Count (TPC) method was used to count the number of colonies. Statistical tests were utilized in data analysis, namely the One Way Anova test (analysis of variance). The results of this study indicated that 395 nm purple LED irradiation caused a decrease in Log CFU/mL of Bacillus subtilis and Escherichia coli bacteria. Inactivation of Bacillus subtilis bacteria showed a higher mortality percentage than Escherichia coli bacteria. Changes in other irradiation distances also showed a higher percentage of death for Bacillus subtilis bacteria than Escherichia coli bacteria. The highest percentage of death was 98.5% for Bacillus subtilis bacteria and 94.3% for Escherichia coli bacteria at position C with an irradiation distance of 3 cm and an energy density of 524 J/cm2 with an LED exposure time of 120 minutes. This shows that the percentage of death of bacteria Bacillus subtilis and Escherichia coli increased with increasing doses of LED energy with the greatest percentage of death in Gram-positive bacteria Bacillus subtilis.Инактивация бактерий может быть выполнена с использованием метода, называемого фотодинамической инактивацией, в основе которого лежит активация фотосенсибилизатора светом определенного спектра. Целью данного исследования является определение эффективности светодиодов с излучением в фиолетовой области спектра для фотоинактивации бактерий Bacillus subtilis и Escherichia coli, а также определение оптимальной плотности энергии воздействия. При облучении были использованы два изменяемых параметра. Первый параметр – это расстояние от источника облучения до облучаемой поверхности (3 см, 6 см, 9 см и 12 см). Второй параметр – время облучения (30, 60, 90 и 120 мин). Для подсчета количества колоний использовали метод общего подсчета чашек (Total Plate Count). При анализе данных использовали статистические тесты, а именно тест One Way Anova (дисперсионный анализ). Результаты этого исследования показали, что светодиодное излучение в фиолетовой области спектра с длиной волны 395 нм вызывало снижение log КОЕ/мл бактерий Bacillus subtilis и Escherichia coli. Воздействие на бактерии Bacillus subtilis показало более высокий процент смертности, чем для бактерий Escherichia coli. Лучшие результаты были получены при расстоянии до источника облучения 3 см, плотности энергии 524 Дж/см2, и времени воздействия светодиода 120 мин. В этом режиме было инактивировано 98,5% бактерий Bacillus subtilis и 94,3% бактерий Escherichia coli

Evaluation of the Electronic Structure Resulting from ab-initio Calculations on Simple Molecules Using the Molecular Orbital Theory

Hartree Fock (HF) and Density Functional Theory (DFT) have been commonly used to model chemical problems. This study uses the Molecular Orbital Theory (MOT) to evaluate the electronic structure of five diatomic molecules generated by HF and DFT calculations. The evaluation provides an explanation of how the orbitals of a molecule come to be and how this affects the calculation of the physical quantities of the molecule. The evaluation is obtained after comparing the orbital wave functions calculated by MOT, HF, and DFT. This study found that the nature of the Highest Occupied Molecular Orbital (HOMO) of a molecule is determined by the valence orbital properties of the constituent atoms. This HOMO property greatly influences the precision of calculating the molecular electric dipole moment. This shows the importance of understanding the orbital properties of a molecule formed from the HF and DFT calculation

Using a Frontline Staff Intervention to Improve Cervical Cancer Screening in a Large Academic Internal Medicine Clinic

BACKGROUND: Cervical cancer is the third most common malignancy affecting women. Screening with Papanicolaou (Pap) tests effectively identifies precancerous lesions and early-stage cervical cancer. While the nationwide rate of cervical cancer screening (CCS) is 84%, our urban general internal medicine (GIM) clinic population had a CCS rate of 70% in 2016. OBJECTIVE: To improve our clinic\u27s CCS rate to match or exceed the national average within 18 months by identifying barriers and testing solutions. DESIGN: A quality improvement project led by a multidisciplinary group of healthcare providers. PARTICIPANTS: Our GIM clinic includes 16 attending physicians, 116 resident physicians, and 20 medical assistants (MAs) with an insured and underserved patient population. INTERVENTION: Phase 1 lasted 9 months and implemented CCS patient outreach, patient financial incentives, and clinic staff education. Phase 2 lasted 9 months and involved a workflow change in which MAs identified candidates for CCS during patient check-in. Feedback spanned the entire study period. MAIN MEASURES: Our primary outcome was the number of Pap tests completed per month during the 2 study phases. Our secondary outcome was the clinic population\u27s CCS rate for all eligible clinic patients. KEY RESULTS: After interventions, the average number of monthly Pap tests increased from 35 to 56 in phase 1 and to 75 in phase 2. Of 385 patients contacted in phase 1, 283 scheduled a Pap test and 115 (41%) completed it. Compared to baseline, both interventions improved cervical cancer screening (phase 1 relative risk, 1.86; 95% CI, 1.64-2.10; P \u3c 0.001; phase 2 relative risk, 2.70; 95% CI, 2.40-3.02; P \u3c 0.001). Our clinic\u27s CCS rate improved from 70% to 75% after the 18-month intervention. CONCLUSIONS: The rate of CCS increased by 5% after a systematic 2-phase organizational intervention that empowered MAs to remind, identify, and prepare candidates during check-in for CCS

A fragment-based approach to assess the ligandability of ArgB, ArgC, ArgD and ArgF in the L-arginine biosynthetic pathway of Mycobacterium tuberculosis.

The L-arginine biosynthesis pathway consists of eight enzymes that catalyse the conversion of L-glutamate to L-arginine. Arginine auxotrophs (argB/argF deletion mutants) of Mycobacterium tuberculosis are rapidly sterilised in mice, while inhibition of ArgJ with Pranlukast was found to clear chronic M. tuberculosis infection in a mouse model. Enzymes in the arginine biosynthetic pathway have therefore emerged as promising targets for anti-tuberculosis drug discovery. In this work, the ligandability of four enzymes of the pathway ArgB, ArgC, ArgD and ArgF is assessed using a fragment-based approach. We identify several hits against these enzymes validated with biochemical and biophysical assays, as well as X-ray crystallographic data, which in the case of ArgB were further confirmed to have on-target activity against M. tuberculosis. These results demonstrate the potential for more enzymes in this pathway to be targeted with dedicated drug discovery programmes

Optimization of phenol degradation and its derivatives using photo-Fenton and application industrial

In industrial effluent are common persistent organic pollutants found that even low concentrations have a high potential carcinogenic and/or mutagenic, such as phenol and derivatives thereof, which poses risks to the environment. This work has identified and measured through high-performance liquid chromatography (HPLC) and its phenol formed as intermediate and also the amount of total organic carbon (TOC). Degradation was evaluated using the same process of photo-Fenton treatment (Fe2+/H2O2/UV) applying annular reactor and a kinetic study was carried out in terms of TOC. The experimental design was the type central composite. In the process used a photochemical reactor annular counter optimized in the following conditions: [Fe2+]=14.15 mg L-1, [H2O2]=1663.40 mgL-1 at pH 3 for 126.18 minutes, obtaining a mineralization 99.89% TOC and [Fe2+]=15 mgL-1 [H2O2]=1800 mgL-1 in 120 minutes a percentage of 100% phenol degradation, respectively. The kinetic model adopted (Lumped Kinetic Model) allowed satisfactory way of representing (R2=0.9892). The photo-Fenton process proved to be efficient for degradation of phenol and intermediates can be incorporated as part of the effluent treatment systems, making it an effective alternative to the complete degradation of the pollutants thereby relieving the impact on water resources and reducing contamination by-products end of the process.
