Grinding is generally carried out in wet conditions, but issues regarding water conservation and high-water treatment costs encourage the application of grinding in dry conditions. Both produce products with certain characteristics that affect the success of the next process. Grinding of P100 6 mesh (3.36 mm) ore was performed using steel ball media with dry and wet grinding with 33.33% solids for 5, 10, 15, 20, 25, and 30 minutes. Particle size distribution of the grinding product was obtained from the wet sieving process and the -200 mesh (-75µm) ore particles were analyzed using a laser diffraction particle size analyzer. The Alyavdin grinding kinetics equation model was used to study the kinetics of ore grinding behavior and the particle size distribution and its characteristics consisting of uniformity index, size modulus and fractal dimension were studied using the logistic, Rosin-Rammler (RR) and Gates-Gaudin-Schuhmann (GGS) equation model. Equivalent particle size (EPS) and specific surface area (SSA) observations were carried out on the -200 mesh (-75µm) grinding product. Grinding in dry condition is more effective in reducing the size of complex galena-sphalerite sulphide ore, indicated by high grinding rate with the highest K value of 0,135/minute, high cummulative % undersize, low size modulus, high uniformity index, high fine particle and high SSA compared to wet grinding. Alyavdin's kinetics model can describe the grinding kinetics of galena sphalerite complex sulfide ore, while the particle size distribution follows the logistic equation model.

Colostrum induced passive immune transfer in lambs
Authors: ÖVET Caner
Published: August 2023

During last decades, the production and consumption of small ruminant milk have been increased. As a result of this, sheep and goat farming have been developing and scientists are focused on clinical and feeding strategy researches on these animals. By the evolutionary challenges and adaptations, colostrum has a crucial role in immune complementation for litter. As a result of these challenges and adaptations neonatal life is more important especially in ruminants due to its lifetime effect and the future of livestock. The passive immune transfer is the main mechanism explained by biological evolution between the dam and lamb which is influenced by certain factors related to both dam and litter. Today the importance of passive immune transfer is well known for the future of livestock economy and animal welfare. In the literature, researchers are focused on correlation between colostrum quality (especially immunoglobulin concentration) and blood serum levels of immunoglobulin levels in newborns. The aims of the present review are to discuss data of recent studies and how passive immune transfer occurred in lambs as well as effecting factors and to supply new ideas to researchers.
An Analysis of the Changes in International Grain Prices on the Domestic Pig Industry and Farm Management
Authors:   Korean Association of Agricultural and Food Policy, Kim Taewoo , Park Dongjoo , Jeon Sanggon
Published: August 2023

This paper analyzes the impact of rising international grain prices on the domestic pig industry and pig farmers. Recently, due to the rise in international grain prices, the increase in feed costs, a major factor in the production costs of domestic pig farms, has pressured the management situation of farmers. Higher production costs due to higher grain prices will reduce the supply of pork, thereby increasing market prices and decreasing market transactions. Accordingly, consumer welfare and producer welfare also decrease. Furthermore, the increase in production costs has a different effect on the degree of productivity of farmers. In particular, the lower the productivity of farmers, the greater the burden of increasing production costs. In this paper, we also analyzed how the effect of increasing production costs varies depending on the degree of productivity of farmers.

Democracy, Decentralization and Political Dynasty: A Case Study of Banten
Authors: Romli Lili , Noor Firman , Rohman
Published: August 2023

Democracy and political decentralization policies aim to enhance and strengthen democracy at the local level in Indonesia. As part of strengthening democratization and decentralization, direct regional head elections were organized and held. However, in several cases the regional head election gave the opportunity for political dynasties to rise and perpetuate the power. In other words, through the election of regional heads, political dynasties enter and survive. The political dynasties have hijacked local democracy through the electoral arena. Such conditions occur in Banten, both at the provincial and district or city levels. The political dynasties in Banten emerged and won the electoral competition. There are several factors that contribute to the emergence and survival of political dynasties in Banten. First, the support of political parties. Second, the weak political elite’s counter. Third, the weakness of civil society power and mass media control. Fourth, the weak of political culture of the society. As an analytical tool, this study uses the theory of decentralization, political dynasties and political culture. The research approach is qualitative by using data collection techniques through in-depth interviews and literature study.

Background: The management and control of gonorrhea are hampered by the widespread resistance to the diverse strains of Neisseria gonorrhea. Resistance to sulfonamides, penicillins, tetracyclines, macrolides, fluoroquinolones, and early cephalosporins has emerged rapidly. Purpose: This systematic review aimed to assess what antibiotics can be used as an alternative therapy for gonorrhea infections that are resistant to antibiotics. Methods: The study was conducted using the Web of Science, PubMed, Embase, and CENTRAL databases, following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement guidelines. Risk of Bias for Randomized Trials (RoB2) was utilized to evaluate study quality. Results: This review included 28 articles from randomized controlled trials between 2013 and 2023, distributed across five nations. The studies included 2.380 patients and clinical isolates from men and women diagnosed with gonorrhea infection at various sites. Sample testing by treatment with alternative antibiotics. Discussion: Zoliflodacin, tigecycline, and ertapenem in single or dual therapy with ceftriaxone could be considered as a potential option in treating gonorrhea resistant to antibiotics. Gentamicin cannot be recommended to replace ceftriaxone as first-line therapy. Gepotidacin is effective for the Gyr A A92T mutation in gonorrhea infection. Summary: The effectiveness of these antibiotics, zoliflodacin, ceftriaxone, gentamicin, gepotidacin, solithromycin, tigecycline, and ertapenem is considered a solution to gonorrhea resistance. Researchers should study how to provide antibiotics with intervening multidrug efflux pumps to overcome gonococcal antimicrobial resistance.

A proxy implementation of thermal pressurization for earthquake cycle modeling on rate-and-state faults

Published: August 2023

The reduction of effective normal stress during earthquake slip due to thermal pressurization of fault pore fluids is a significant fault weakening mechanism. Explicit incorporation of this process into frictional fault models involves solving the diffusion equations for fluid pressure and temperature outside the fault at each time step, which significantly increases the computational complexity. Here, we propose a proxy for thermal pressurization implemented through a modification of the rate-and-state friction law. This approach is designed to emulate the fault weakening and the relationship between fracture energy and slip resulting from thermal pressurization and is appropriate for fully-dynamic simulations of multiple earthquake cycles. It preserves the computational efficiency of conventional rate-and-state friction models, which in turn can enable systematic studies to advance our understanding of the effects of fault weakening on earthquake mechanics. In 2.5D simulations of pulse-like ruptures on faults with finite seismogenic depth, we find that the spatial distribution of slip velocity near the rupture front is consistent with the conventional square-root singularity, despite continued slip-weakening within the pulse, once the rupture has propagated a distance larger than the rupture width. An unconventional singularity appears only at shorter rupture distances. We further derive and validate numerically a theoretical estimate of the fracture energy dissipated by thermal pressurization in earthquake cycles. These results support the use of fracture mechanics theory to understand the propagation and arrest of very large earthquakes.

Background: Personality disorders (PDs) are often comorbid with obsessive-compulsive disorder (OCD) which may influence symptom presentation and course. This investigation sought to examine the impact of comorbid PDs on clinical presentation and symptom chronicity in a large, prospective longitudinal OCD study. Methods: Participants (n=263) were treatment-seeking adults with a primary diagnosis of OCD separated into two groups: individuals with and without a co-occurring PD. We conducted two-tailed t-tests to compare symptom severity, functioning, and quality of life between the OCD + PD group (n=117) and the OCD w/o PD group (n=146). Chronicity analyses were conducted to compare the amount of time in-episode for OCD and major depressive disorder (MDD) between the two groups. Results: The OCD + PD group reported greater OCD and depression severity, lower levels of psychosocial functioning and worse quality of life than the OCD w/o PD group. The OCD + PD group exhibited greater OCD and MDD symptom chronicity; over 5 years the OCD + PD group spent 16.2% weeks longer at full criteria for OCD and three times as many weeks in episode for MDD than the OCD w/o PD group. Limitations: Focusing on PDs as a group limited our ability to make observations about specific PDs. Further, the participants in our sample were predominantly White and all were treatment seeking which limits the generalizability of our findings.Conclusions: Our results suggest that those with OCD and comorbid PDs present with greater overall impairment and may require additional considerations during treatment conceptualization and planning.

Misinformation remains a serious problem and continues to be a major focus of intervention efforts. Psychological inoculation - a popular intervention approach wherein people are taught to identify manipulation techniques - is being adopted at scale around the globe by technology companies in an effort to combat misinformation. Yet the efficacy of this approach for increasing belief accuracy remains unclear, as prior work has largely focused on technique identification - rather than accuracy judgments - using synthetic materials that do not contain claims of truth or falsity. To address this issue, we conducted 5 studies with 7,286 online participants using a set of news headlines based on real-world false and true content in which we systematically varied the presence or absence of emotional manipulation. Although an emotional manipulation inoculation video did help participants identify emotional manipulation (replicating past work), there was no carry-over effect to improving participants’ ability to tell truth from falsehood (i.e. no effect on truth discernment). Encouragingly, however, when the emotional inoculation was paired with an accuracy prompt - i.e., an intervention intended to draw people’s attention to the concept of accuracy when they are receiving the inoculation intervention - the combined intervention did successfully improve truth discernment by increasing belief in true content. These results generate new insights regarding inoculation, and provide evidence for a key synergy between two popular psychological interventions against misinformation.
Fast and frequent corrections of saccadic decisions underlie a satisficing strategy when searching everyday scenes

It remains unclear how and how much visual mechanisms integrate visual information across fixations. We analyze three large eye-movement datasets from human observers free-viewing or searching for category-defined targets in photographs of everyday scenes (COCO-Search18, COCO-FreeView and 900 Scenes). During goal-directed search, fixation periods with strikingly short duration (< 125 ms) form over a third of all fixations after the first saccade. Visual information obtained during these short-duration fixations cannot influence the following short?latency saccade, which therefore has to be executed based on target identity and location information carried over from previous fixations. Short-latency saccades are goal-directed: they foveate the search-target more often than other (regular-latency) saccades. Active searching and search-target salience increase the frequency of short-duration fixations. Human searchers use a satisficing strategy based on information transfer across saccades that aids minimizing the cost of making additional saccades to non-target stimuli.

Research on causal beliefs about mental illness—the beliefs people hold about what causes a particular mental illness, or mental illnesses in general—is split across a number of areas, including research on the common-sense model of self-regulation, explanatory models, mental health literacy, biogenetic causal beliefs, and more. Although research on this subject has provided a number of insights and practical applications, the diversity of theories, disciplines, and keywords makes it challenging for a new reader to gain a comprehensive understanding. We conducted a two-stage systematic review of the literature on causal beliefs for mental illness, including a narrow search using terms referring specifically to causal beliefs (864 included articles) and a follow-up search using a comprehensive set of terms relevant to research on causal beliefs (3,830 included articles). We provide a comprehensive summary of these literatures in terms of their history, typical research questions and study design, findings, and practical applications. We conclude by making recommendations for future research on causal beliefs for mental illness, as well as whether and how this research might inform effective public health campaigns and clinical practice.

Springs are the major sources of water in Nepal, but the springs are drying up fast due to, among others, climate change, ill-engineered infrastructure and associated disasters. A huge sum of money is invested in water supply projects and a significant percentage of those have become nonfunctional due to source drying. Most of the projects consider the supply side only- not sustainability. By that, the scarce public investment is wasted. Hydrogeological aspects including climate change, and source conservation were never been realized. Once the sources dry up, projects become redundant. People look for alternative sources requiring scarce public investment. Therefore, the Government of Nepal and development partners like Renewable World (RW) concluded that the sustainability of water projects is crucial and must be considered in the initial phases of project development. It can be assisted and achieved by hydrogeological evidence-based water source conservation planning. To implement it, an interdisciplinary research team of Nepal Water Conservation Foundation and RW conducted a hydrogeological study including the climate impacts and participatory planning applying different sets of tools and methods applied in social and natural sciences such as hydrogeological study, key informant interviews, focused group discussions and policy assessment. Consequently, 10 site-specific source protection and conservation plans for solar MUS schemes were developed. The study found four types of variables: (i) Precipitation and temperature: There was no significant impact of climate change in terms of rise in temperature and precipitation; (ii) Problems related to conservation: The major problems included drying up and displacement of springs by flood, landslide and road constructions; pollution through agricultural runoff, livestock grazing, and contamination by pesticides and chemical fertilizers; disappearance or conversion of traditional wallowing/recharge ponds; contamination and damage by flood; (iii) Innovation: Even a small innovation like Solar MUS can contribute in people’s life significantly through lifting water from downhill sources; (iv) Planning: Source protection and conservation plan can be formulated democratically and owned by local government and water user groups and implemented jointly.
