Berdasarkan letak astronomi Indonesia yang terletak pada garis khatulistiwa, maka sangat pantas atau layak jika Indonesia mengembangkan PLTS sebagai teknologi dalam mengimbangi tuntutan manusia terhadap ketergantungan akan listrik. Indonesia juga memiliki iklim tropis (terdiri dari 2 musim, panas dan hujan), sehingga penyinaran matahari di wilayah Indonesia (± 12 jam) cukup untuk menjadikan PLTS sebagai solusi untuk tuntutan kebutuhan akan listrik. Salah satu teknologi yang digunakan dalam PLTS tersebut adalah panel surya. Panel surya mampu mengkonversi cahaya matahari menjadi listrik secara langsung. kinerja panel surya dipengaruhi oleh beberapa faktor ialah radiasi matahari, suhu dan kecepatan angin. Perhitungan dan analisis terhadap hasil pengukuran memperlihatkan bahwa kualitas kinerja sel surya tidak terlalu baik, yaitu sebesar 0,143 untuk sel surya tanpa reflektor, 0,156 untuk sel surya dengan reflektor atap galvalum dan 0,157 untuk sel surya dengan reflektor aluminium foil. Dan efisiensi pada sel surya tanpa reflektor sebesar 7,48 %, untuk sel surya dengan atap galvalum sebesar 8,75 %, dan untuk sel surya dengan aluminium foil sebesar 9,72 %

Scottish Northerners in Alba Amicorum, c. 1540–c. 1720
Authors: Brochard Thomas 
Published: November 2023

The present article draws together two seemingly irreconcilable threads: firstly, the perceived and stereotyped violent, retrograde and inward-looking northern Scot and, secondly, the lettered world of humanist Europeans on the move as encapsulated in the tradition of alba amicorum (friendship albums). By reconciling these seemingly antinomic worlds of northern Scotland and humanist, scholarly culture, alba help redefine and nuance these Highlanders' and northern Scots' identity, culture, and character, which are more in line with these qualities associated with the world of alba, attesting to this group of Scottish northerners' integration into the intellectual and humanist networks then present in Europe. For these individuals, theirs was a Gaelic and/or Scots culture and its appreciation which was complemented with an awareness of and a thirst for a Latinate and Classical culture and an openness to a European and word culture, by playing tourist on the Continent and being receptive to this new and foreign environment. Far from being impervious to other cultures, they opened themselves to these and welcomed foreign visitors. The roles were reversed and, in turn, they acted as guides to these tourists visiting Scotland and their communities. Through alba, it is possible to gain a better understanding of early tourism in Scotland and of tourist sites in northern Scotland, putting them not only in a national context but also an international framework.

The territories once occupied by the Ottoman Empire, replete with cultural abundance, have perennially captivated the attention of explorers. Bursa stands as a quintessential city, epitomizing the cultural opulence of the Ottoman heritage. With this value, Bursa has attracted the attention of foreign travelers for centuriesand travelers have visited this city for various reasons. Visits began in the 15th century, increased in the 19th centuryand many diplomats, merchantsand scientists came to the city. Most of the travelers who came also explored and researched the Hisar District, the historical center of Bursa.
When looking at the 19th century, it becomes evident that, just as in previous centuries, the Hisar District, in addition to the city's overall social life and cultural wealth, has garnered the interest of travelers. Within the societal urban structure of Hisar, historical edifices, its architectural fabric, monumental structures, the fort's layout, religious establishmentsand other social constructs have amplified this interest. For this reason, the district is deemed significant by these travelers. They have articulated their perspectives about the Hisar District in their travelogues. Furthermore, travelers have elaborated on the Hisar District's physical structures, its history, architectureand artistic attributes in their writings.

Background: Currently, the mechanism(s) underlying corticogenesis is still under characterization.Methods: We curated the most comprehensive single-cell RNA-seq (scRNA-seq) datasets from mouse and human fetal cortexes for data analysis and confirmed the findings with co-immunostaining experiments.Results: By analyzing the developmental trajectories with scRNA-seq datasets in mice, we identified a specific developmental sub-path contributed by a cell-population expressing both deep- and upper-layer neurons (DLNs and ULNs) specific markers, which occurred on E13.5 but was absent in adults. In this cell-population, the percentages of cells expressing DLN and ULN markers decreased and increased, respectively, during the development suggesting direct neuronal transition (namely D-T-U). Whilst genes significantly highly/uniquely expressed in D-T-U cell population were significantly enriched in PTN/MDK signaling pathways related to cell migration. Both findings were further confirmed by co-immunostaining with DLNs, ULNs and D-T-U specific markers across different timepoints. Furthermore, six genes (co-expressed with D-T-U specific markers in mice) showing a potential opposite temporal expression between human and mouse during fetal cortical development were associated with neuronal migration and cognitive functions. In adult prefrontal cortexes (PFC), D-T-U specific genes were expressed in neurons from different layers between humans and mice.Conclusion: Our study characterizes a specific cell population D-T-U showing direct DLNs to ULNs neuronal transition and migration during fetal cortical development in mice. It is potentially associated with the difference of cortical development in humans and mice.

AimsRecent studies have shown that mineralocorticoid receptor antagonists (MRAs) can decrease mortality in patients with heart failure; however, the application of MRAs in current clinical practice is limited because of adverse effects such as hyperkalemia that occur with treatment. Therefore, this meta-analysis used the number needed to treat (NNT) to assess the efficacy and safety of MRAs in patients with chronic heart failure.MethodsWe meta-analysed randomized controlled trials (RCTs) which contrasted the impacts of MRAs with placebo. As of March 2023, all articles are published in English. The primary outcome was major adverse cardiovascular events (MACE), and secondary outcomes included all-cause mortality, cardiovascular death, myocardial infarction (MI), stroke, and adverse events.ResultsWe incorporated seven studies with a total of 9,056 patients, 4,512 of whom received MRAs and 4,544 of whom received a placebo, with a mean follow-up period of 2.1 years. MACE, all-cause mortality, and cardiovascular mortality were all reduced by MRAs, with corresponding numbers needed to treat for benefit (NNTB) of 37, 28, and 34; as well as no impact on MI or stroke. MRAs increased the incidence of hyperkalemia and gynecomastia, with the corresponding mean number needed to treat for harm (NNTH) of 18 and 52.ConclusionsThis study showed that enabling one patient with HF to avoid MACE required treating 37 patients with MRAs for 2.1 years. MRAs reduce MACE, all-cause mortality, and cardiovascular death; however, they increase the risk of hyperkalemia and gynecomastia.

BackgroundUltrasound-guided percutaneous device closure of perimembranous ventricular septal defects (PmVSD) is a minimally invasive recent treatment approach. Perventricular PmVSD device closure is an emerging radiation-free intervention, yet it comes with certain limitations. No studies compared both of these treatment approaches.MethodsWe performed a retrospective institutional data comparison of percutaneous (PCP Group, n = 138) and perventricular (PVP Group, n = 67) ultrasound-guided device closure procedures in 205 patients with PmVSD between March 2017 and December 2022.ResultsPatients of the PCP and PVP groups had a median age of 4.9 years (IQR, 3.1–14.0) and 5.3 years (IQR, 3.4–13.1) respectively. The median PmVSD diameter in the PCP Group was 4.0 mm (IQR, 3.3–5.3) and 5.2 mm (IQR, 4.0–7.0) in the PVP Group (p = 0.001). There was no significant difference in success rates between the PCP and PVP Groups (intention-to-treat population, 88.4% vs. 92.5%, p = 0.36; as-treated population, 88.4% vs. 89.3%, p = 0.84). 5/8 failed percutaneous cases that were shifted to the perventricular approach were successful. Compared to the PVP Group, patients of the PCP group experienced a significant decrease in ventilation time, drainage volume, and postoperative hospital stay (p &lt; 0.001). The median follow-up period was 24 months (IQR, 6–42) for the PCP group and 61 months (IQR, 53–65) for the PVP group. The overall severe adverse event rate was 0% in the PCP group and 3.0% in the PVP group.ConclusionsPerventricular and percutaneous ultrasound-guided device closure of PmVSD are both effective and safe treatment options. The percutaneous approach offers less trauma and faster recovery and may be the preferred approach in selected patients.
Environmental conditions predetermine quality, germination, and innate antioxidants pool in sea oat (Uniola paniculata L.) seeds
Authors: Egesa Andrew Ogolla , Pérez Héctor E. , Begcy Kevin 
Published: November 2023

Secondary metabolites such as antioxidants are critical components that protect seeds from stress damage during seed development, desiccation, and ex-situ storage. Antioxidants are essential determinants of seed quality, longevity, and persistence. Understanding the environmental factors that regulate the accumulation, content, and function of antioxidant pools in sea oat seeds is critical for gene banking and understanding the environmental impacts on seed quality. Germination, viability, and Trolox Equivalent Antioxidant Capacity (TEAC) were analyzed on seeds from 18 sea oat populations from the US Atlantic and Gulf of Mexico coasts. We first assessed baseline TEAC, followed by TEAC performed on imbibed seeds for 36 h at 35/25°C during the day and night, respectively. Then, we analyzed the relationship of the antioxidant pools from these 18 sea oat populations to sampling site environmental classifications. Higher baseline antioxidants were common in regions with extreme environmental conditions corresponding to sea oat populations growing at latitudinal extremes characterized by warmer and colder temperatures. Baseline antioxidants did not correlate with prevailing seed germination. However, higher concentrations of antioxidants following imbibition were associated with poor seed germination in warmer conditions. Our results indicate that climatic conditions and environmental components associated with temperatures and precipitation may largely influence the innate pool of antioxidants in sea oat seeds. Also, a high amount of antioxidants following sea oat seed imbibition suggest seed damage or poor viability influenced by environmental stress conditions during seed development.
Internet perceptions among older adults in Sweden
Authors: Bergström Annika 
Published: November 2023

IntroductionThe digital inequality is still present after decades of development and diffusion of digital media. Age is one of the most important factors predicting access, use, skills, and outcomes, which is somewhat paradoxical as information and communication technologies can create opportunities for older adults to sustain independent living. To increase understanding of older adults' online engagement, this study focuses on perceptions of the internet usage and how it can be a useful tool in everyday life.MethodA representative survey (n = 841).ResultsAnalyses point to decreasing support for the internet with increasing age - also within the group of 66 to 85 years old. There are significant correlations between perceptions and internet experience, whereas sociodemographic factors have weak explanatory power. Interestingly, large shares of older adults do not have any opinion of the internet, which could partly explain the persistence of the digital divide and difficulties to increase digital literacy.DiscussionOnline experience and level of anxiety overrule socio-demographics in explanatory power to perceptions. The internet is perceived useful, but also interferes with common habits, the view of digital technology in everyday life and computer anxiety. The findings could affect policy implementation, where it would be useful to implement the idea of the Internet and create an awareness that might precede an intention to advance one's use.
Modulation of optical absorption and electrical properties in Mn-Co-Ni-O-based high-entropy thin films
Authors: Ma Chao 
Published: November 2023

High-entropy thin films of Mn0.6Co0.6Ni0.6Mg0.6Cu0.6O4, Mn0.6Co0.6Ni0.6Mg0.6 Zn0.6O4, and Mn0.6Co0.6Ni0.6Cu0.6Zn0.6O4 (MCNMC, MCNMZ, and MCNCZ) with equiatomic proportions were synthesized using chemical solution deposition on silicon substrates. Structural analysis confirmed a consistent face-centered cubic spinel structure, while significant differences in surface morphology were observed. Quantification of the valence states of Mn ions revealed an inverse variation in the concentrations of Mn4+ and Mn2+ ions. The heightened infrared light absorption of the MCNMC thin film was assigned to Cu-induced Jahn-Teller distortion and highly polarized Mg-O bonds. All samples exhibited negative temperature coefficient behaviors in their electrical properties. Additionally, the MCNMC thin film demonstrated the lowest resistance due to its denser microstructure, close proximity of Mn3+/Mn4+ ion concentrations, and additional Cu+/Cu2+ ion pairs, enhancing small polaron hopping conductivity. In contrast, the MCNMZ thin film showed moderate resistance but boasted the highest thermal constant (B25/50) of 3768 K, attributed to its distinctive grain chain structure, facilitating carrier transport while introducing migration barriers.

PurposeAlthough corticosteroids are recommended in the 2021 Surviving Sepsis Campaign (SSC) guidelines, evidence with respect to their effects on short-term mortality remains conflicting. We conducted this study to identify whether corticosteroids alter 28-day mortality in septic shock patients with gram-negative bacterial infection.Materials and methodsA total of 621 patients with septic shock and gram-negative bacterial culture results were identified from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. Propensity score matching (PSM) was performed, and Kaplan–Meier survival curve analyses with log-rank tests were used to determine the relationship between corticosteroid use and the risk of 28-day mortality. Subgroup analyses were conducted to assess whether the conclusions were stable and reliable.ResultsCorticosteroid administration was associated with increased 28-day mortality in septic shock patients with gram-negative bacterial infection (log-rank test P = 0.028). The incidence of Stage 2 or 3 AKI and the rate of hospital mortality were higher among patients who received corticosteroids. The incidence of Stage 2 or 3 AKI in the early period significantly mediated the relationship between corticosteroid use and 28-day mortality [P =0.046 for the average causal mediation effect (ACME)]. Interaction tests indicated that the effect of corticosteroid use was maintained in patients with a neutrophil-to-lymphocyte ratio (NLR) of &lt;20 (P-value for interaction = 0.027).ConclusionSystemic corticosteroid use could be harmful in septic shock patients with gram-negative bacterial infection, especially in patients with relatively low NLR.
