Failure-mode index

Search what already failed

A searchable index of real negative results, null findings, and replication failures from the published literature — so you can learn what didn't work before repeating it.

WASTE indexes published research — it does not host or republish full papers. Each entry is a metadata record (title, authors, DOI) compiled from open scholarly databases, with the abstract shown in full only where the paper is openly licensed (e.g. Creative Commons); otherwise a short excerpt is shown for reference under fair use. WASTE classifies each work by failure type; classifications are automated and approximate.

Muhammad Abba Isah Audu, Yusuf Idris, Muhammad Liman Muhammad et al. · 2022 · Botanica

The nutritional attributes of sesame, Sesamum indicum, vary substantially and are primarily influenced by the plant’s genetic makeup. This investigation accessed the biochemical composition of sesame mutants from two generations. Seeds of eleven M3 lines were planted in a Randomized Complete Block Design (RCBD) to raise M4 lines, which were advanced to M5 generation. The seeds were harvested at maturity, and their biochemical compositions were quantitatively determined following standard procedures. Results revealed significant differences (p 0.05) was observed in ash content of M4 and M5 muta

An extended research of crossmodal correspondence between color and sound in psychology and cognitive ergonomics

Xiuwen Sun, Xiaoling Li, Lingyu Ji et al. · 2018 · PeerJ

Based on the existing research on sound symbolism and crossmodal correspondence, this study proposed an extended research on cross-modal correspondence between various sound attributes and color properties in a group of non-synesthetes. In Experiment 1, we assessed the associations between each property of sounds and colors. Twenty sounds with five auditory properties (pitch, roughness, sharpness, tempo and discontinuity), each varied in four levels, were used as the sound stimuli. Forty-nine colors with different hues, saturation and brightness were used to match to those sounds. Result revea

QIAN Ren-dong, WANG Lian-sheng, LUO Qiao-hua et al. · 2023 · Siliao yanjiu

The purpose of the study was to investigate the effects of wheat gluten replacing fish meal on growth performance, serum biochemistry, liver antioxidant and intestinal digestive enzyme activities of Cyprinus carpio . A total of 180 healthy Cyprinus carpio with an initial body weight of (9.16±0.03) g were selected and divided into three experimental groups, with three replicates in each group and 20 fish in each replicate. The control group (CW) was with 5% fish meal, and the experimental groups were with 50% (WA) and 100% (WB) fish meal replaced by wheat gluten. The experiment lasted for 56 d.

Resistance of High-Volume Fly Ash Self-Compacting Concrete to Internal Sulfate Attack

Tareq Al-Attar, Ahmed Taha · 2018 · Engineering and Technology Journal

This paper investigates the durability of high-volume Fly ash self-compacting concrete, HVFASCC that exposed to internal sulfate attack. At the present work, HVFASCC was produced with two Fly ash replacements: 50 and 60% by weight of Portland cement. The internal sulfate attack was simulated by adding natural gypsum (CaSO4) that contain ion (SO3-2) to fine aggregate by two weight percentages: 1 and 2%. Limestone dust was used as filler with a content of 100 kg/m3. The cementitious materials, cement and Fly ash, content was 400 kg/m3 and the water to powder ratio for the studied mixes was 0.34
